CARD OR PAMPHLET HOLDING DEVICE.

Application filed August 5, 1925.

This invention relates tov improvements in card or pamphlet holding mechanism. More particularly, the invention relates to devices of that character designed especially for use in connection with bread wrapping machines for the purpose of delivering cards, or pain-- phlets, into the wrapping machine for enclosure within the wrapped loaves of bread.

It is the principal object of the present invention to provide a device that is an improvement over the device disclosed in my co-pending application filed February 24, 19%, under Serial Number 695,751, and by means of which cards, or pamphlets, may be delivered, one at a time, onto the loaves of bread just prior to their being wrapped in that it may be filled from the top and is designed for mounting outside of the wrapping machine whereas the other was inside.

Other objects of the invention reside in the various details of construction and combination of parts as will hereinafter be described which produces a more efficient and more easily handled mechanism.

In accomplishing the objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wh-erein Figure 1 is a side elevation of a card or pamphlet feeding device embodied by the present invention.

Figure 2 is a horizontal scc'ional view of the same taken on the line 2-2 in Figure 1.

l igurc is a view of the device from the front end.

Figure 4: is a vertical section through the feeding device taken on the line 4-4 in Figure 1, showing the feed rollers and the adjustable card stack supporting means.

The present device differs from the device of the co-pending application, above mentioned, in that it is designed to feed the cards or pamphlets fromthe bottom of the stack instead of from the top. The advantage of this resides in the fact that it may be refilled while the wrapping machine is in motion and not requiring any stopping of the bread feeding or wrapping mechanism as was necessary in the use of the other device.

The device, in its present construction, comprises a frame structure consisting of four vertical posts 1 that are joined rigidly in spaced relation by horizontal pieces 2 pro- Serial No. 48,235.

which two. parallel, spaced apart feed shafts 5 and 6 are rotatably extended. The stack 3 is supported at its opposite edges just above these feed shafts by means of the inturned end portions 8 of vertical bars 9 that are located at opposite sides of the hopper and are adjustably fastened by set screws 10 to the horizontal pieces 2 so, that they may be adjusted to lower or raise the stack for the purpose of varying its distance above the feed rollers. The set screws extend through vertical slots 10 in the pieces 2 and are fixed at their inner ends in the bars 9.

The feed shafts 5 and 6 are each equipped with a pair of feed rollers 11 having flexible lingers 12 extended so as to wipe the lower end of the stack as the rollers revolve to thereby deliver the, pamphlets therefrom into a downwardly inclined chute 13 that is supported in the lower end of the frame. At their forward ends the two feed shafts are equipped, as shown in Figure 3, with int-ermeshing gears 15 and 16 of equal size so that the shafts are caused to rotate at the same rate and in opposite directions. The shaft 5 is extended at one end, as shown in Figures 1 .and 2, and is operatively connected through gear sets 17 and 18 and shafts 19 and 20 with a gear 21 which operates in mesh with a gear 22 that is fixed to a rotatable part of the wrapping mechanism with which the device is used. Through this mechanism the device is synchronized with the wrapping machine so that it will deliver one pamphlet or card for each loaf of bread delivered into the machine. The wrapping machine has not been illustrated, but the loaves are delivered thereto, as shown in Figure 4, beneath the end of the chute 13.

The driving of the shafts 5 and 6 is such that the feed rollers turn toward each other at the top and the feed fingers 12 engage the bottom pamphlet of the stack so as to draw its ends from the supports 8 and fold it downwardly between the feed rollers and shafts as shown in Figure 4.

In order to time the delivery of the pamphlets to the loaves of bread, as the latter are delivered into the wrapping; machine beneath the discharge end of the chute 13, I have provided the stop or release lever 25 which is pivotally supported by a pin 26 from a cross piece at and extends horizontally over the shaft 5 and is then turned laterally and has a down-turned end 27 extended into the chute in. position to catch and retain the pamphlets delivered thereinto. A cam 29 is mounted on the shaft 5 and this operates the shaft revolves to engage with the lever to cause it to he lifted at the proper time to release the pamphlet or ird so that it will drop onto the loaf as the loaf passes beneath the lower end of the delivery chute.

it is to he understood that the card feeding device may be mounted on the wrapping machine in any suitable manner and may be driven by any suitable mechanism, it being important only that the two machines be synchronized so that the pamphlets will be delivered into the wrapping machine at the same rate as the articles to be wrapped are delivered.

rtssuming that the device is so constructed and that it is attached properly to the wrapping macl'iine for use, it is first tilled with a supply of cards or pamphlets which are stacked within the hopper and are supported by the ends 8 of the bars 9; the latter being adjusted vertically so as to support the lower end of the stack at the proper distance from the feed rollers. lVhen the machine is in operation, the fingers 12 of the feed rollers engage the lower card of the stack with each revolution and cause them to be fed into the hopper one at a time where they are retained temporarily by the end of the lever. The cam 9.8 is properly set on the shaft 5 to engage and lift the lever to release the pamphlets as the loaves are delivered beneath the end of the chute so that a card will be delivered onto each loaf just before the wrapper is applied.

The device may be easily filled and does not require that the machine be stopped for this purpose.

Having thus described my invention, what I claim as new therein and desire to secure by Letters-Patent, is:

1. A device of the character described, comprising a frame structure provided at its lower end with a delivery chute, a pair of feed shafts extended in parallel relation and in the same horizontal plane through said frame, friction feed rollers on said shafts, a pair of vertically adjustable bars within the frame at opposite sides and having inturned ends adapted to support a stack of pamphlets from their opposite edges just aeove the shafts, and means for rotating the shafts at the same rate and in opposite directions to cause the feed rollers to engage with the bottom of the stack to feed the pamphlets therefrom down ardly between the shafts into the chute.

2. A device as in claim 1 provided with means operable by the rotation of one of the feed shafts for timing the delivery of the pamphlets from the chute.

A. device of the character described, comprising a frame structure provided at its lower end with a delivery chute, a pair of feed shafts extended in parallel relation and in the same horizontal plane through said frame, friction feed rollers on said shafts, a pair of vertically adjustable bars within the frame at opposite sides and having int-urned ends a stack of pamphlets edges just above the shafts, and means for rotating the shafts at the same rate and in opposite directions to cause the feed rollers to engage with the bottom of the stack to feed the pamphlets therefrom downwardly between the shafts into the chute, a lever pivotally fixed to the frame overlying one of the feed shafts and having an end portion extended in the path of delivery of pamphlets from the chute and a cam on the shaft operable to lift the lever to release the pamphlets for delivery.
