JERSEY.

OF PATERSON, NEW JERSEY, A CORPORATION OF NEW MACHINE FOR USE IN HANDLING BLANKS.

Application filed March 31, 1919. Serial No. 286,615.

T 0 all whom it may concern:

Be it known that I, LEWISJ. BAZZONI, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Use in Handling Blanks, of which the following description, in connection with the accompanying drawings, is a specification, like referonce characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in handling blanks and is herein illustrated as embodied in a machine for use in handling uppers of shoes.

It is customary in some shoe factories to tie the uppers in bundles of a given number--commonly thirty-six-after they have been finished by the vamper preparatory to taking them to the assembler. Hitherto the vamper has been accustomed to pile the finished blanks one by'one beside her on the bench which supports her sewing machine as fast as she has finished them and then to tie them in bundles of the required number.

Inasmuch, however, as it isdiflicult for her to keep track at all times of the number of finished uppers in the pile, she almost invariably recounts them before tying them up. In fact, the partly completed piles are often counted several times at different stages owing to interruptions in the work of the operator which causeher to forget how many uppers the piles contain.

One object of this invention is to relieve the operator of the necessity of counting the blanks which are being handled, thus avoiding inaccuracy and insuring against interruption and delay in the progress of the work such as that resulting more or less frequently from necessary recounting of the blanks.

WVith this object in view, one'feature of the invention consists in the provision of a support constructed and arranged to sink as blanks are piled upon it one by one, an indicator, and means independent of the support and arranged to be actuated by the blanks as theyare moved toward the pile for operating the indicator. In the illustrative machine the support is vertically movable and balanced so that it may gradually sink as the pile 'of blanks increases. This support is placed at the side of the vamper and has overhanging it an end of an actuator in the form of a lever, downward movement of the overhanging end of which operates the indicator With such a construction the vamper, by wiping each upper across the end of the lever as the upper is being placed upon the pile, operates the indicator which will then show at any time just how many blanks the pile contains.

Uppers of shoes are bulky and do not lend themselves readily to the formation of a stable pile. According to another feature of the invention there is provided a presser which normally rests upon the top of the pile but is withdrawn when the actuator is moved. In the illustrative machine the presser is connected with the actuator, both members being held in their normal positions by means of a weight. When the actuator is moved by engagement with a moving blank in the hand of the operator, the presser is withdrawn from the pile to permit the blank to be added to the pile. By this time the actuator has been released, and the presser is returned by the action of the weight to engagement with the top of the pile.

These and other features of the invention, including certain details of construction and combinations of parts, will be described as embodied in an illustrative machine and pointed out in the appended claims.

Referring now to the accompanying draw- 1ngs,

Fig. l is a perspective of a machine in which the present invention is embodied;

Fig. 2 is a cross-section showing the actuator depressed and the presser withdrawn from the pile, and

Fig. 3 is a cross-section showing the actuator and the presser in their normal positions. In this figure a partly finished pile of uppers is also shown.

The machine may conveniently be mounted upon a bench 5 at the side of the vamper, the bench being the same one upon which the sewing machine (not shown) of the manipulation of the actuator for moving the presser.

5. A machine for use in handling blanks, having in combination, a support upon which blanks may be piled, a presser normally in position adjacent the support, an actuator therefor, means responsive to movement of the actuator for moving the presser away from the support, and means operating when the actuator isreleased to return the actuator and the presser to their normal positions.

6. A machine for use in handling blanks, having in combination, a support upon which blanks may be piled, a presser capable of being withdrawn from and returned to engagement with the pile, and an actuator arranged to be engaged by a blank as: it is being added to the pile for operating the presser to permit the addition of the blank and to hold it after it has been added.

7. A machine for use in handling blanks, having in combination, a movable support upon which blanks may be piled, a presser normally in engagement with the pile, an

actuator, and means whereby movement of the actuator in one direction withdraws the presser from the pile and in the other direction returns the presser to engagement with the pile.

8. A machine for use in handling blanks, having in combination, a movable support upon which blanks may be piled, a presser normally in engagement with the pile, an

actuator, and means whereby movement of the actuator in one direction withdraws the presser from the pile and release of the actuaton permits return of the presser to engagement with the pile.

9. A machine for use in handling blanks, having in combination, a support on which blanks may be piled, a presser normally in position adjacent the support, an actuator therefor normally in a position more remote from the support than is the presser, and means responsive to movement of the actuator toward the support for moving the presser away from it.

10. A machine for use in handling blanks, having in combination, a support on which blanks may be piled, said support being movable and balanced so that the top of the pile may remain always approximately in the same plane as blanks are added to it, a presser normally in position adjacent the support, an actuator therefor normally in a position more remote from the support than is the presser, and means responsive to movement of the actuator toward the support for moving the presser away from it.

11. A machine for use in handling blanks, having in combination, a support upon Which blanks may be piled, an actuator arranged normally in position to be engaged and moved by each blank as it is being placed upon the support, means for returning the actuator to its normal position when its engagement with the blank ceases, a presser normally held in contact with the pile, and connecting means between the presser and the actuator constructed and arranged to withdraw the presser to permit each blank to be added to the pile, and then to return the presser to normal position.

12. A machine for use in handling blanks,

having in combination, a vertically-movable, balanced support upon which blanks may be piled, a presser movable into and out of engagement with the pile, an indicator, and means pivo-tally connected to the. presser for opearting the indicator.

14. A machine for use in handling blanks having, in combination, a. balanced support constructed and arranged to descend as blanks are piled upon it one by one, an actuator adapted to be engaged and moved by each blank as it is being added to the pile, a presser adapted to engage the uppermost blank in the pile, connecting means between the presser and the actuator constructed and arranged to withdraw the presser when the actuator is moved by a blank to permit the blank to be added to the pile, a fixed stop operating through said connecting means to determine the normal position of the actuator and the presser, and a weight operating through said connecting means to return the actuator and the presser to their respective normal positions after each blank has been added to the pile.

15. A machine for use in handling blanks, having in combination, a support upon which blanks may be piled and counted, an actuator arranged norm-ally in position to be engaged and moved by each blank as it is being added to the pile, means for re turning the actuator to its normal position when its engagement with the blank ceases, a presser normally held in contact with the pile, and connecting means between the presser and the actuator constructed and arranged to withdraw the presser to permit each blank to be added to the pile and then to return the presser to normal position.
