This improved sheet assembling machine has a casing I formed of metal and supported in vertical spaced relation to a base 2 by struts 3. The casing l is drum shaped and within it is mounted a drum 4 which isalso formed of sheet metal and has its peripheral wall covered by a facing 5 of rubber. The shaft 6 of the drum is journaled through side walls of the casing and may be turned through the medium of a crank handle I or driven from a motor 8 mounted externally of the casing and having its shaft provided with a worm 9 which meshes with a worm gear l0 carried by the shaft. The handle I may be removed when the shaft is driven by the motor.

Sheet holders in the form of boxes II, I! and it, are spaced from each other circumferentially of the casing, the box ll being mounted on the base i and the boxes li'and I3 being mounted outwardly of the casing by brackets Na and Ma fixed to and extending from the peripheral wall of the casing. By this arrangement, blank checks may be stacked in box H, carbon sheets in box l2, and record sheets in box i3. It will be understood that this is merely one type of sheets which may be assembled by the sheet assembling machine and that the machine may be used for assembling other sheets in regular order. It will also be understood that the machine is not limited to three boxes and that the number may be increased in accordance with the number which the dimensions of the casing will accommodate.

Each box is formed as shown in Figs. 3 and 4, and referring to these figures, it will beseen that the box has top or inner wall sections it and. I5 spaced from each other to provide an opening it through which sheets of paper are to be discharged from a stack ll of paper mounted withthe line 8-8 of in the box. The stack 11 rests on a'backing' plate" which fits loosely within the box and is formed with side tongues l8 engaged through slots 28 formed in side walls of the box. A spring 2| urges the stack of sheets toward the wall sections I4 and I 5 and the tongues guide movement of the backing plate. Openings 22 are formed in side walls of the box near the discharge end of the box, to accommodate rubber rollers 23 carried by shafts 24 which are mounted in ears '25 projecting from side walls of the box. A spring clip 28 yieldably resists turning of each shaft 24, but since the shafts and their rollers 23 are rotatable, the sheets may be shifted from under the wall section i4 for delivery to the drum. A lip 21 extends from the wall section I4 toward the casing and is curved so that when an end portion of a sheet is detached from the stack and lands upon the lip, it will be directed toward the casing and into engagement with a roller 28. The rollers are opposite openings 29, 30 and 3| formed in the peripheral wall of the casing, and each roller is urged toward the casing for engagement with an exposed portion of the drum by a spring 32 coiled about the stem 23 of a yoke 34 by means of which the roller is rotatably mounted. The stems of the yokes pass through ears 35 which project; from the end wall of the box near which the rollers 23 are located, and, as a detached end portion of a sheet slides along the lip 21 toward the casing, it will be engaged by the cooperating roller 28 and pressed against the rubber facing 5 of the drum. Each of the sheets is detached from its stack in this manner and applied to the drum or gatherer 4 and it will be understood that as the gatherer rotates, the sheets will be successively extracted from the boxes and deposited, one upon another, to provide collected or assembled sheets which are three in number in the illustrated embodiment of the invention.

In order that the sheets may be extracted from the boxes, they must have end portions withdrawn from under the walls sections l4 of the boxes. To accomplish this, there have been provided shoes 38 which are mounted adjacent ends of the openings 29, 38 and 3| of the casing. Each shoe is carried by a rod or shaft 31 which is journaled through the casing transversely thereof, as shown in Fig.' 7. An arm 38 is secured upon each shaft 31 by a set screw 38, and since the arm is adJustably carried by the shaft, it may be shifted along the shaft into and out of position for engagement by the abutment pin 40 protruding from a side of the drum. Springs 4| which have their ends anchored to the casing, and the arms 38, yieldably hold the shoes out of position to engage the sheets, but as the drum turns the abutment pin will successively engage the arms and cause the shafts and the shoes carried thereby to be rocked in a direction to swing the shoes to the position indicated by dotted lines in Fig. 3. During this movement, a shoe will engage a sheet of a stack of sheets exposed through the opening l8 of a box, and the end portion of the sheet wihch is engaged under the wall section l4, will'be kicked loose, as indicated by dotted lines in Fig. 3. The abutment pin or finger then moves out of engagement with the arm and the spring returns the arm and shoe to the initial position which permits the sheet to slide forwardly over the lip 2! of the box and into engagement with the applying roller 28 which presses the sheet against the rubber facing of the rotating drum and causes the sheet to be withdrawn from the box. This operation is repeated at each box and the sheets will be assembled in sets, there being three sheets to each set in the present instance.

In order to receive the assembled sheets or sets of sheets, there have been provided trays or receptacles 42, 43 and 44. These receptacles are arranged in a vertical tier and supported upon a bracket 45 fixed to the peripheral wall of the casing l. A door 46 which is hinged at its lower end, as shown at 41, constitutes a closure for the outer ends of the receptacles and is releasably held in raised or closed position by clips 48 at opposite sides of the upper receptacle.

Chutes 48, 58 and 5| extend from the inner ends of the receptacles and converge toward their free ends. As assembled sheets are discharged from the upper end of the receptacle by the roller 28 of the upper box I3, they pass over a platform 52 onto a shelf 53 which has its inner end pivoted to the platform, and this shelf is of such length that by tflting it vertically, it may be moved into position to direct the assembled sheets onto the chutes for delivery into the receptacles. A tongue 54 extends from a side of the shelf and rests on the upper end of a rod 55 which is slidable vertically in the casing through a bearing sleeve 56 carried by a side wall of the casing. This rod has its lower end resting on a cam disk 51 which is fixed to a gear 58 by a suitable number of rivets 59. The gear and the cam disk are secured on a shaft 60 by a key 6|, the shaft being rotatably mounted in brackets 52 and the gear 58 meshing with a smaller gear or pinion 63 fixed to the drum shaft 8. By this arrangement, the shaft 60 and the cam disk will be turned in time relation to the drum and, as the segments of the cam disk move into engagement with the lower end of the rod 55, the rod will be reciprccated vertically and the platform moved from one chute to another. Therefore, the assembled sheets will be successively delivered to the receptacles 42, 43 and 44. As the assembled sheets accumulate in the receptacles, the door 46 will be opened and stacks of assembled sheets removed from the receptacles. A clip 64 is slidably mounted against the under face of the chute 50 and,-from an inspection of Fig. 5, it will be seen that when the clip is shifted outwardly, the platform 53 will be prevented from tilting downwardly below the chute 50 and assembled sheets will only be delivered to the receptacles 42 and 43. Such an arrangement will usually be made use 'of when sheets are only stacked in the boxes l2 and I3, but it is to be understood that delivery of assembled sheets to the lower receptacle may be eliminated whenever desired.

This machine is particularly adapted for manufacturing companies doing a large business and having a very large number of invoices and bills to send to their customers. Many companies send duplicate bills or invoices so that the customer can attach his check to the one being paid and this greatly aids the manufacturer in keeping accurate accounts as he can tell at a glance which invoice or bill a check received is to cover. When the duplicate invoices or bills are sent out to a customer, one is an original and the other a carbon copy and from an inspection of Fig. 1, it will be readily understood that by placing bill heads in the boxes I l and I3 and sheets of carbon paper in the box [2, the machine can then be operated and each group discharged will consist of two bill heads and a sheet of carbon paper therebetween. After the bills have been typed it is necessary to separate the carbon papers from the bills. This is accomplished by placing the assembled sheets in one box and then operating the machine to successively discharge the bills and the sheetsof carbon paper onto the platform 53. This platform is tilted vertically by. the rod 55 to successively move it into cooperating relation to the chutes 49, 50 and SI, and the bills and carbon papers will be separate from each other,
