To provide for releasing the trip latch, its lower end is provided with a foot piece 55, engaged by an arm 56, Figures 2 and 3, carried by a rock shaft5'l having a short arm 58 in the path of the short arm 59 of a lever, which is pivoted at 60 to the floor of the cabinet and has an operating arm BI extending through a slot in the floor to a point substantially underneath the paper exit slot l5. The lever 5! is preferably a wide plate, having a lower end portion over which the delivered paper may be fed, and after a delivered section has been severed this wide flat arm of the lever will be exposed.
Until the delivered portion of the web has been severed on the tear-off knife, the manually operable arm SI of the releasing lever is not merely concealed from view but is rendered relatively inaccessible by the portion of the web depending below the cabinet from the dispensing slot 55.
Thus, while the severance of the projecting portion of the web on the tear-off knife I4 is not absolutely prerequisite to the release of the detent to permit another operation of the feed roll, the tearing of the projecting sheet portion of the web is nevertheless a usual preliminary to the actuation of the release mechanism.
If the arm 6| is pulled forwardly by the operator its motion will be transmitted through its short arm 59, arm 58 of rock shaft 51, and its longer arm 55 to depress the trip latch 42 and release the slide 35. Thereupon the slide 35 will be restored to its normal position by its spring 48, and its finger 36 will drop by gravity from the top 52 of the cam gear to its full line position as shown in Figure 3. All of the parts will then have been restored to normal position ready for the release of another sheet section by pressure upon the handle or pin 39 to again retract the controlling slide 35.
The upward urge of the trip latch 42 may be varied by varying the tension of'its spring 45. To accomplish this, a spring tensioning lever 65 is employed. The spring 45 is attached to the inner arm of this lever. The other arm of this lever extends through a slot in the control box and is provided with a detent, .as indicated at 68, to engage teeth 6! formed in one wall of the slot. Downward movement of the protruding end of the lever, including lateral movement to release it from the engaged tooth Bl, will increase the tension of the spring 45, whereas a reverse movement will decrease its tension.
From the foregoing description it will be understood that the improved cabinet has its outfeeding slot flanked on one side by a severing blade and on the other side by the exposed arm of a setting lever permitting operation of interior feed control mechanism. After adjusting the same lever to permit operation of the feed con- 7 trol mechanism, slide 35 returns to normal posiexposed operating piece 39'.
Also, that when such adjustment is made, an outfeeding mechanism can be operated to a limited extent to feed through the slot a portion of the paper strip of predetermined length, whereupon the above described cycle of operations must be repeated before the feeding of another measured strip can be accomplished.
The feature of organization, which locates the latch releasing lever behind the discharging sheet or section of the strip, is important. While the latch releasing arm 6| is normally in plain view, it is concealed as soon as the discharging paper moves down in front of it, and the operator will not be tempted to reach around the paper strip and pull the lever forwardly simply for the purpose of enabling him to continue the delivery by again pushing on the arm or pin 39 as soon as the outfeeding operation is stopped by the cam gear.
Therefore, each sheet will ordinarily be torn away when the feeding stops, and if another sheet is desired, the lever M will then be pulled forwardly to renew the cycle of operations.
We claim: 1
l. The combination of a dispensing cabinet for rolled paper strips, said cabinet having an outfeeding slot and a manually movable releasing member behind the path of paper delivered through the slot, normally locked feeding mechanism within the cabinet adapted, when unlocked, to be manually actuated to deliver a measured portion of the strip through said slot, a one-way operable unlocking device, a trip for preventing return of the unlocking device to normal position, and means for transmitting movement of the releasing lever to retract the trip and allow the unlocking device to return to normal position for a succeeding unlocking movement.
2. In a slotted cabinet provided with means for supporting a rolled paper strip and outfeeding mechanism for delivery of the strip in successive sheets through the slot in the cabinet Wall, the combination with such outfeeding means of locking mechanism normally preventing its operation, an unlocking slide cooperative with the locking mechanism to limit the extent of each outfeeding operation, an automatically actuated latch for preventing a return of the unlocking slide for a succeeding unlocking operation, and oscillatory means operable from the exterior of the cabinet to release said latch and permit such return.
3. A dispensing cabinet for rolledpaper strips, having an outfeeding slot and a normally locked interior outfeeding roller, a control slide within the cabinet and associated means for unlocking the roller for limited feeding movement, means for manually operating the control slide in one direction from the exterior, an interior trip for automatically preventing retraction of the control I pensing a web from a roll, said mechanism comprising feeding means and measuring mechanism for limiting each operation of said feeding means to the delivery of a predetermined length of said web, of a detent requiring release prerequisite to each operation of said feeding means, a tear-off knife disposed forwardly of the path of web delivery and a manually operable member in operative connection with said detent for the release thereof, said member being disposed behind the path of delivery of said web by said feeding means, whereby to be inoperable by said web during severance of a delivered length thereof and positioned to be materially obscured from view by the delivered portion of the web prior to its severance.
5. The combination with means for supporting a roll and feeding a web therefrom, of measuring mechanism in operative connection with said means comprising a stop actuated by said means and engageable with said means after a predetermined actuation to restrict said means against delivery of more than a given portion of web from said roll in a single operation, and mechanism for controlling the resetting of said stop to permit a further operation of said means, said mechanism comprising a manually operable trip disposed behind the path of advance of a web delivered by said means and operatively connected to move forwardly in its resetting of said stop, whereby said trip will be inoperable by pressure of said web and materially concealed by said web pending the severance of the concealing portion of said web from the remainder thereof.
6. The combination with web feeding and measuring mechanism provided with a detent for limiting the operation of said mechanism for the control of the length of web dispensed in each operation thereof, of a trip requiring resetting prerequisite to the release of said detent and disposed at the rear of the path of material delivered from said mechanism and operatively connected to move forwardly in its resetting of said stop, whereby to be inoperable by pressure of said web and materially concealed by the deliv- 40 ered web pending the removal thereof.
said slot for the delivery of a web therethrough,
said mechanism comprising a releasable detent for restricting the operation of said mechanism to the delivery of a predetermined length of web, and a trip operatively connected with said detent for the release thereof and comprising a lever pivoted to said first means behind said slot and having a manually operable portion movable toward the path of web delivery through said slot in the course of its trip releasing movement, and said portion being positioned to be substantially obscured by the delivered web pending the removal thereof.
8. The combination with a dispensing cabinet for a paper web, said cabinet having a downwardly opening transversely extending outfeeding slot and provided at one side of said slot with a sheet severing blade andat the other side with a manually movable releasing lever pivoted to said cabinet for forward movement from a normally retracted position toward the path of a web dispensed through said slot and positioned to be substantially concealed by a web portion delivered from the slot, of interior feeding mechanism adapted to deliver a measured portion of web through said slot, a latch requiring retraction prerequisite to the operation of the feeding mechanism, and latch retracting connections between said manually operable releasing lever and the latch and subject to actuation in a latch releasing direction upon a forward movement of the lever upon its fulcrum respecting said cabinet after the web is cut off by said sheet severing blade.
