SAFETY SAW-GUARD.'-

Be it knownthat I, GEORGE II. ADAM, a citizen of the United States, resident of Cineinnati, in the county-of I-I-amilton and State of Ohio, have made a certain newand useful Invention .in Saw-Guards; and I declare the ,following to" be a full, clear, and exact description of the same, such as will enable others skilled inthe art to which it appertains to make and use the. invention, reference being had to the accompanying drawings, and to letters 'or figures of reference marked thereon, which form a part of thisspeciication.

` Figure 1 'is a side view ofthe invention as applied.4 Fig. 2 is an end viewof the same.- Fig. 3 is a plan view'of the invention. j

y .The-invention has relation to 'saw'guarda` .having for itsobjectI to provide a guard which will be equally useful when .the table isA level, and when it is tilted -to a high angle. Other objects and advantages will herein'- after appear.` f

The invention consists in the novel" con-v struction and combinations of parts, as here -inafter set forth.

In the accompanylngdrawings, illustrating the invention, the numeral 1 designates the saw, 2 the' sawtable, and 3 the support-l ing frame',l the saw being arranged at one side of the table, so that the table may be tilted to the-desired angle in the usual manner. Overlying'the saw vis the'top guard 4,

' preferably pivoted at its .rear Aend at. 5 to the standard 6, located inthe rear of the saw, the yoke 6 of said standard being bolted to the frame 3 vin the usual manner..

The top guard is preferably provided at its rear end with a vertical slot', in which fits the plate-form upper end portion- 8 .of said standard, to -prevent"any lateral .movement of the guard, the pivot pin passing. through the branches of the rear endof the guard at the sides of the slot land through the` standard. The forward end 'of the top guard is bent downwardly at 9 toward Athe saw table, and is provided 'with van uptu'rjned or cam end 10, a ro']ler 11 being carried by' -the forward end of the guardE and resting normally upontlle saw table,'.reducing friction when the wood ispassed to the saw loe-v tween the roller andthe table, the top guard being lifted upon its. pivot in this operation.

At each sidepf thetop guard is provided a( lateral-shield or guard 12, pivoted at its' infront end tothe 'front elfld of the top guard Specification of Letters Patent. Pia'gtmtedl Jun@ 3Q), 1914i; nemica-tion ala June 27, 191e. serial No. 776,195.

at'13, just in the rear of the cam end and plicate at Ithe sides of the'tcp guard to ac*- commodate the twolateral guards.. The lateral guards have sliding adjustment in the slots 14 when'the'y are .raised upon-their pivots, and are limited in their .downward movement by stop projections 16, engaging the upper surface of the top guard. The lateral projections or lugs 15 of the top guard being extended downwardly below the upper plate part of this guard, and the slots 14 being likewise extended, lthe lateral guards will be held accurately to movement in a vertical plane.

Should it be required to tilt thesaw table to a. high angle as great as degr.ees,'the inner of the lateral hinged guards will be automatically 4,adjusted to still-,guard the saw in proper manner, being raised upon its forward hinge -by Contact with the upper surface ofthe table. Theouter of the lateral guards will, in the tilted position of the table, and in its normal position, still guard the saw at this side. Either of the lateral guards maybe raised upon its pivot to inspect the saw' or the wood.

-movement or kickof the wood very dangerousfto the operator. A

-"lll1e/ blade standard 6, is sharpened to' a knife edge in front, land is preferably itemovably fitted in a'slot .17, of the yoke 6',

the standard having a vnotch 18, in its bot- 100, edge, of the standard bearing against a pin tom engaging 'a pin 19,0f the yoke, the rear 20, of the yoke.' WhatI claim is :f 1. Ina saw guard, a supporting member,

'and a normally substantially horizontal side guard ateach side carried by said supporting member both side guards being .loose 'and independently movable with relation to each other,-whereby they are' capable ,'ofas..'y 110- sumng simultaneously dierent inclinations, '2. In asaw guard, asupporting-member pivoted in rear, anda normally substantially hqrizontalside guard at each side pivoted 4in front to said supporting member both side guards being loose and independently .movable pon their pivots with vI'elation'toI each other, whereby they are capable of assuming simultaneously different inclinations. y

3. In a saw guard, a top gard pivotedin `rear and having-lateral guides, ya normally both side guards Working in rear in said rear substantially horizontal side guardai: eachside pivoted in front to said top guard,

guidesand being loose 'and independently movable upon their pivots With respect to each other,whereby they are capable'of as,-

su'ming simultaneously dierent inclinations. 15 l VIn testimony'yvhereof I aixgmy signature, in presence ofutw-owitnesses. n
