The present invention relates to a sheet assembly device and has for its principal object the provision of means whereby a multiplicity of sheets can be assembled manually into overlapped relation so that each one of the sheets has a portion thereof along one edge exposed when the group is assembled. The invention contemplates means for securing the sheets together so that they may be handled as a unit for use in duplicating work where it is desired, for example, to take oli' on separate sheets the several lines of a single record. One application of the unit strips is in the making out of checks from a payroll sheet. The checks are printed up and the information fmm'the payroll sheet is applied by making a master sheet and then applying this master sheet tov the several checks arranged in overlapped relation.

One purpose of the present invention is to provide a novel sheet guide and holding device in combination with a glue applying mechanism adapted to apply an adhesive at spaced points along one edge of a sheet.

It is also a purpose of the invention to provide a novel sheet arranging device by means of which several sheets can be positioned in overlapped relation with uniform spacing.

The detailed purposes and advantages of the invention will appear more fully from the following description, reference being had to the accompanying drawings wherein a preferred form of the invention is shown. It should be understood however that the drawings and description are illustrative only and are not to be taken as limiting the invention except insofar as it is limited by the claims.

Figure 8 is a sectional view taken on the line 8-8 of Figure '1.

Referring now in detail to the drawings, the present invention comprises means for assembling a plurality of sheets I0 together in overlapped relation as shown in Figure 2 of the drawings so that each sheet has one edge Il exposed when viewed from the top. Sheet assemblies of this type are generally referred to as unit strip assemblies and have a. variety of uses in the making and keeping of records by duplicating processes such as hectograph duplicating and liquid or wet process duplicating'. The advantage of the assembled units lies in the fact that they may be used together for the purpose of taking informa tion individually to each sheet of the unit from a single master copy having thereon a line of individual information for each of the sheets. In order for the unit strip assemblies to function properly the overlapping, to provide the portions ll must be very accurate otherwise the information will not be properly placed on each sheet when the unit assembly is brought in contact with the master copy. It is likewise essential that the several sheets be secured together with sumcient permanence to enable them to retain their overlapped position during the duplicating operation. Likewise it is essential that the sheets be readily separable after the duplicating operation so that each sheet may be used individually. The securing means which has been found to be most elective comprises small spaced spots l2 of adhesive along one side edge of -each sheet or where desirable along both side edges.

For the purpose of assembling and adhering the sheets together I provide on a suitable support Il an adhesive applying device AI4 and an assembling device l5 on which the sheets areassembled in proper alignment after the adhesive is applied thereto. These two devices, although physically independent. cooperate to provide the sheet asgrooves being equally spaced. In each groove a bar 2D is mounted. The bars 20 have a portion 2l fitted in the groove and firmly securedV therein, for example, by gluing. Also, each bar has a flange 22 extending at right angles to the portion 2l and parallel to the plate I 8 but spaced above the plate suiliciently to readily receive the side edge of a sheet between it and the plate. Immediately above the upper bar 28 a flat. thin strip 23 is mounted on the plate I8.

In order to provide an adjustable side guide for the sheets I8 the plate I8 has two

angle irons

24 and 25 secured thereto, one of the angle irons being secured at the upper edge of the plate I8 and the other one being secured at the lower edge of the plate. These angle irons project slightly above the plate and are provided with

slots

28 and 21 extending almost full length thereof. A side guide 28, also in the form of an angle iron, extends from one of the slots 28 to the other slot 21. The side guide is adjustable and maybe clamped in any desired position along the

slots

28 and 21 by

suitable clamping devices

29 and 30. These clamping devices are alike and a description of one will sufllce for both. An aperture is provided in the horizontal flange of the member 28. A bolt 3| is supported upon a sleeve 32 and passes through the horizontal flange of the member 28 and through the slot in the

corresponding angle iron

24 or 25. The bolt threads into a block 33 beneath the horizontal flange of the associated angle iron, and has a flattened head as shown so that it can be tightened or loosened by hand. The side guide 28 is provided with a plurality of depending lugs 34 to extend down between the spaced members 20 and prevent sheets from getting caught beneath the side guide 28.

The manner in which the sheets are assembled in overlapped relation is indicated in Figure 3. The first sheet of a group has its edge stuck underneath the upper one of the members 20. The next sheet is positioned with one edge under the next lower member 20 and the sheets are stacked in this fashion until the desired number for the unit to be made have been arranged in overlapped relation. When the sheets are placed in -position they are pressed down against the sheets already in place and are adhered to them by means of the spots of adhesive.

Referring now to Figures 1, 6, 'l and 8, the adhesive applying device I4 is shown as mounted on an auxiliary base 35 immediately alongside the assembly frame. This base has two

angle irons

36 and 31 fastened thereon and the angle irons carry a bracket 38 which is of inverted U-shape. On the top of the bracket 38 two

flat bars

39 and 48 are fastened and the two flat bars have secured thereto a sheet 4I which is provided with an elongated slot 42 about midway between its side edges. The sheet 4I may desirably be welded to the

bars

39 and 40 and to the brackets 38. An edge guide for the sheets to which the adhesive is to be applied is made up of a flat strip 43 which is provided with elongated slots 44 and 45 at its opposite ends and a narrow thicker strip 46 which is fastened to the underside of the strip 43 by screws 41. Two

screws

48 and 49 which pass through the slots 44 and 45 and are threaded in the bracket 38 and the

bars

39 and 40 serve to adjustably secure the sheet guide in place.

An adhesive container 50 is of such size that it may slide readily between the flanges of the

angle irons

36 and 31 and engage against the bracket 38. This container 50 is held in position by a set screw 5I that is threaded into the flange of the angle iron 31. The end of the container adjacent the angle iron 36 has a pin 52 projecting outwardly near its upper edge and adjacent the rear wall of the container. The container has a shaft 53 journaled therein extending between the two end walls and lying adjacent the front wall. This shaft has two

hand levers

54 and 55 fixed thereon. The hand lever 55 is also a position limiting lever as it has an extension 56 that is tapered at its end as indicated at 51 so that when the shaft is in the position shown in Figure 6 the end 51 rests on the horizontal flange of the angle iron 28. When the shaft is turned counterclockwise the portion 56 engages the pin 52 to thus limit the movement of the shaft. A series of spring ngers 58 are mounted by means of adjustable collars 58 on the shaft 53. These ngers are adapted. when lowered, to dip into a. quantity of adhesive 68 in the container 5|! and when raised their upturned tips 6| pass through the slot 42 to engage the strip 43.

In order to apply adhesive to a sheet by means of the fingers 58 the sheet is inserted, as shown in Figure 6, between the strip 43 and the plate 4| so as to extend over the slot 42. Then one of the hand levers is pressed down to cause the fingers to engage the undersurface ofthe sheet. If it is desired the sheet can be reversed and adhesive can be applied to the other end in the same fashion. For many purposes, however, applying the adhesive spots I2 by means of the fingers 58 to one end edge of a sheet will provide suilicient adherence for the sheet assembly to be used as a unit. As soon as the adhesive has been applied the sheet is positioned on the plate I8 with the adhesive carrying edge against the side guide 28. Since the adhesive is applied on the underside of the sheet the bottom sheet, that is, the first one applied to the plate I8, need not have any adhesive thereon, but the second sheet, when laid over the rst sheet, ls pressed down so as to cause the adhesive spots to secure the two sheets together. The operator continues to apply adhesive and assemble the sheets in this fashion until he has the desired number for a group. Normally the adhesive dries fast enough that when the group is completed it can be removed without disturbing the alignment of the several sheets.

From the foregoing description it is believed that the nature and advantages of the present invention will be readily apparent to those skilled in this art.
