COMBINATION SPLIT-RIM TOOL AND LONG JACK.

Specification of Letters Patent. Patented Feb, 14, 1922,

Application filed November 22, 1920. Serial No. 425,827.

\ To all whom it may concern.

Be it known that I, HERRMANN B. TOBIAS, a citizen of the United States of America, and a resident of the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a new and Improved Combination Split-Rim Tool and Long Jack, and do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawin s, forming a part of the specifications, an to the reference numbers marked thereon.

My present invention relates to a tool intended to facilitate the separation of any split rim from the tire it supports and thereplacement of same, and also to facilitate the jacking up of an automobile or the extraction of such vehicle out of a roadhole.

The main object of the invention is to provide a tool that is simple to operate and of sufiicient strength to perform the aforesaid operations, with the maximum saving of time and labor.

, In carrying out my invention I provide two members held in sliding contact, having means at one of their ends for gripping .the rim, and means for bearing on the ground and supporting the load, and an operating device with control mechanism for varying the relative position of the two sliding members.

Figure 1 shows the tool in the vertical position as used for jacking up an automobile.

Figure 2 shows the outside view of the control or operating box, taken on line 2-2 of Figure 12, looking in the direction of arrows.

Figure 3 is a top view of the control box taken on line 3-3 of Figure 2, looking in the direction of the arrows.

Flgure 4 1s a cross section through the control box,- taken on line 1 of Figure 2 box on line 6- 10 of Figure 12 looking in the direction of the arrows and showing the tool in one position for expansion release.

Figure 8 1s a section through the control box on line 610 of Figure 12 looking in the direction of the arrows, and showing the tool in another position for expansion release.

Figure 9 is a section through control box on line 6--10 of Figure 12, looking in the direction of the arrows, and showing the tool in one position for contraction release.

Figure 10 is a section through control box taken on line 6-10 of Figure 12, looking in the direction of the arrows, and showing the tool in another position for contraction release.

Figure 11 is a cross section of the two sliding members taken on line 11-11 of Figure 10 looking in the direction of the arrows.

Figure 12 is cross section, through the control box taken on line 12 -12 of Figure 2, looking in the direction ofthe arrows.

Figure 13 is a cross section through the control box taken on line 13-13 of Figure 10, looking in the direction of the arrows.

This tool, as a combination split rim tool, towing jack and lifting jack, is designed to perform different functions, -the first being the expansion which lengthens the tool; the second being the expansion release which reduces the length of the tool when under expansive load; the third being the contraction which shortens the length of the tool from any chosen extended position, and the fourth being the contraction release which lengthens the tool when under contracting load.

A further fuction is to enable the closing of this tool when not in use.

A main frame 14 is provided having at one end a hook 15 intended to grip the edge of a split rim for contraction purposes, and a push lug 16 intended to engage the inner face of a split rim for expansion purposes; also a bearing end 17 for resting the tool on the ground when in a vertical position.

. This main frame is for the present purpose shown in the form of an H and so arranged as to receive within it the sliding member 18. v

This sliding member 18 is provided at one end with a hook 19 for gripping the edge of a split rim for contraction purposes, and a pushlug '20 for engaging the inner surface u b c of the mm for expansion purposes and 1s also provided with a saddle 21 at the end to receive the load imposed upon it when used in the vertical position as a jack, or in any other position for pushing purposes.

The sliding member 18 is further provided on top of its H section with integral lugs 22 equally spaced throughout most of its length and intended to be engaged by the operating device as will be hereinafter described.

The control box of this tool is secured to the end of the main member 14, opposite the gripping means 15 and 16 above described, and is formed of two cover plates 23 and 24 held together by the rivets 25 passing through said main frame 14, housing therein the controlling and operating mechanism as hereinafter described.

Integral with the cover plates 23 and 24' are bearing flanges 26 and 27 which support through a rivet 28, the operating handle 29 and the double ratchets 30 and 31.

These two double-ratchets are so arranged and linked, as will be noted, that while the tool is in operation they are free to act independently of one another, andwhen the action of the tool is to be reversed from the expansion as shown in Figure 5 to the contraction as shown in Figure 6, the swinging of either one of the double ratchets .through the fork of the operating handle,

would pull along the other ratchet.

Ratchet 30 is supported by pin 28 through hub 32 with which it is integral and slides freely between the side arms 33 and 34 of the ratchet 31.

Lugs 35 and 36 are provided on the ratchet 30 and serve to engage the side arms 33 and 34 of ratchet 31 when reversion takes place from contraction to expansion positions.

The lugs 36 are longer than lugs 35 so as to also en age the releasing mechanism.

Similar y lugs 37 are provided integral with ratchet 31 and on the same side with the lugs 36 of ratchet 30, and of such length as to engage the releasing mechanism.

The points of the ratchets are mainta ned in engagement with the lugs 22 by springs 38 engaging the extensions 39 integral with hub 32 of ratchet 30 and by spring 40 engaging the extensions 41 integral with hub 42 of ratchet 31. These springs, as will be noted, are so arranged that through all cycles of operation they will maintain the points of these ratchets in contact with lugs 22, except at such time as the releasing mechanism prevents it.

The ratchet 31 is supported by forking arms 43 and 44 of the operating lever 29 through the bosses 45 and 46 engaging perforations in said forking arms, said bosses being integral respectively with the hubs 42 and 47 which in turn are a part of the supporting side arms 33 and 34 of ratchet 31.

It will be notedthat there is no connection between the hubs 47 and 42, thus allowing a space through which the body of the ratchet 30 can swing when reversion from expansion to contraction takes place.

The operating arm is limited in its swing through the are 48, by extensions 49 at the end of forked arm 43, which engages the checking plate 50, sliding between the walls 51 and 52 integral with the control box cover plate 23.

This checking plate is held in this position, as shown in Figure 15, through all the four main operations aforementioned by cam 53, which is integral with control button 54.

This control button supports in addition, two other earns: 55, which acts *upon the expansion releasing dog 56 and cam 57 which acts upon the contraction releasing dog 58.

The controlling button is supported in bearing 59 of the cover plate 23 and is held in position by the sliding checking plate 50.

For operating purposes a lug 60 is provided on the outside of the operating button formed like an arrow, the direction of said arrow indicating the desired action of the tool and the releasing mechanism.

It will therefore be understood that when the arrow points as in Figure 2 towards the legend Closed it will allow the checking plate 50 to be pushed within the control box and withdraw its obstruction to extensions 49 of the operating handle 29 allowing said handle to be folded for closing the tool as in Figure 2.

This controlling button and the cams integral therewith have four phases of operation: first in the position shown in Figure 2, which allows the tool to be closed; second, when pointed toward the legend Expansion release it operates on the releasing mechanism for expansion through the releasing dog 56; third, when pointed toward legend Neutral it allows the ratchets to work freely for expansion or contraction, and fourth, when pointing toward legend Contraction release it operates on the releasing mechanism for contraction through the releasing dog 58, all as will be noted by its various positions in Figures 5 to 10 inclusive.

The releasing dogs 56 and 58 are supported through the hubs 61 and 62 by bosses 63 and 64 integral with cover late 23.

' The releasing dogs are provi ed with lugs 65 and 66 to be engaged by springs 67 and 68, which springs are coiled around the hubs 61 and 62 and held in position thereby.

The ends of the releasing dogs opposite to the hubs are provided with an irregular formed edge havlng a curved surface 69 and a depression 70 intended to be engaged respectively by the lugs 37 and 36 of the ratchets 31 and 30 during the releasing action.

To hold the sliding member 18 in-contact with the main frame 14, hearing lugs 71 and 72 are provided inte ral with the cover plate 23, and lugs 73 and 4 are provided integral with the cover plate 24, all four being of such a length as to penetrate through corresponding perforations in the enlarged flanges, 75 and 76 of the main frame 14 and frictionally engage flanges 77 and 78 of the sliding member 18.

The operation of the jack and rim tool can be easily understood by following through, the positions shown in Figures 2 and 5 tov 10 inclusive, assuming the tool is used in the Vertical position as a jack, all. as follows:

In Figure 2, the tool is in a closed position with the holding ratchet 30 and propelling ratchet 31 folded within the forks 43 and 44 of the operating arm 29, the checking plate being pushed in against the fiat end of the cam 53 by the projection 49 in the fork of the operating handle.

To expand the tool the two ratchets are placed as in position shown in Figure 5 and the control button 54 is turned with the arrow pointing towards Neutral, which acts through the triple four-function cam by pushing the checking plate 50 out to limit the travel of the operating handle.

In this position the cams 55 and 57 hearing against the release dogs 56 and 58 hold them in an inactive position against the expansive energy of the springs 67 and 68 allowing the vertical movements of the operating handle to lift gradually the sliding member 18 in relation to the main frame 14.

In Figure 6 the tool is set for Contraction by swinging the ratchets through the fork of the operating handle to the position shown, and maintaining the control button 54 in the same position, pointing toward Neutral, the arrows 80 showing the direc tion of the force against which the tool is operating; the releasing mechanism being held in the same position as shown in Figure 5.

Figure 7 shows the tool in position for Expansion release in which case the contro'l button 54 is turned with the arrow pointing towards the-legend Releaseon the Expansion side of control box, which action allows the spring 67 through its expansion to push the release dog 56 outward into active position while the releasing dog 58 is held in the inactive position, the releasing action being as follows:

In Figure 7, the propelling ratchet 31, instead of engaging recess 81 as would be the case for expansion, is forced to slide over same by the edge 69 of the releasing dog and engage the higher recess 82 when the operatin handle is moved upward.

when this handle reaches its limit of upward movement as shown in Figure 8, the

propelling ratchet 31 assumes the load exerted by the force 80 and allows spring 67 to push the release dog 56 out the necessarydistance required to allow recess of the release dog to engage the holding ratchet 30 and lift it out of engagement with the lugs 22 of the sliding member 18 holding it in this position until lug 37, of the ratchet 31, coming down under the action of force 80, bears against the edge 69, of the release dog 56, forcing it within the control box after the recess 83 has passed by, the engaging edge of the holding ratchet 30, allowing said ratchet 30 to assume the load by engaging the recess 81 by the time the operating handle has reached its downward limit of travel. .Upon the upward move of the o crating handle the releasing operation wou d be repeated.

- The final stages in the sequence of release are shown in Figures 9 and 10, but in the reversed positions for the Contraction release.

The releasing operation for the fContraction release is similar to that for Expansion release, after the control button 54 has been turned with the arrow 60 pointing toward the Release mark on the Contraction side of the control box, in which case, the release dog 56 is held inactive while the release dog 58 is forced into active position by the expansion of thespring 68.

The releasing action heretofore described, is possible because springs 67 and 68 have greater expansive force than the action of the springs 38 and 40, upon ratchets 30 and 31.

The releasing dogs 56 and 58 are forced into the control box by the load upon the sliding member 18, looking through the .lugs 22, the engagement point of the ratchets 30 and 31 and through said action exerting a greater force upon the release dogs than that of the springs 67 and 68.

The action of the tool in a horizontal position is the same.

Its use as a rim tool is shown in Figure 1, where the rim 85 is shown in its position for contraction at which time the tool is assumed to be in a horizontal position.

After the air is discharged from the tire and the lock ofthe split rim is released, the hooks 19 and 15 engage the flanges of the rim as shown by dotted lines 85 and with the ratchets in the position shown in Figure 6 the movement of the operating handle 29 throu h the are 48 coils the split the ratchet in the position'as shown in said figure and also in Figure 5, under which condition the movement of the operating handle 29 through the are 48 will force the rim, by the expansion of the tool, to its normal circumference and position on the tire, ready for locking. 7

Used as a jack the base 17 of the main frame 14 rests on the ground while the saddle end 21 engages and supports the load that it is to lift or push.

It will be noted that the construction of this tool and its double action allows it to be built of a length as shown and can therefore be used when a wheel is caught in a deep road depression to lift same out to the road level by placing this tool against the said wheel in an oblique position and expanding it, or it can be used for towing purposes when in a horizontal position with the ratchets in position shown in Figure6 and the hooks 15 and 19 engaging some towing material such as ropes or chains, etc.

It is evident from the above description that a great force can be exerted by the leverage of the operating handle and the ratchet, changing the relative position of the sliding members in two directions with their accompanying release, thereby serving the purpose of this invention.

Although this tool is illustrated as manufactured of malleable iron it is evident that it is also adapted to be constructed from stamped or wrought metal with slight variations in details of parts, without affecting the purpose of the invention.

I therefore do not wish to be restricted to the exact details of construction or sections shown or described for, as has been indicated, it is obvious that a combination of a split rim tool and long jack with slight modification from the above, but comprising two sliding members held in engagement, their ends equipped to engage a tire rim or chains and further equipped to enga e loads for lifting or pushing purposes and t e relation of said sliding members to each other controlled through a lever by linked and reversible propelling ratchets so as to act both in an expansive and contractive direction for the purpose of exerting a great pull or push, and their corresponding releases and control will come within the scope of my invention.
