Application December 13, 1947, Serial No. 791,535

,of one face of the stack incidental to forming scratch and like writing pads.

One of the primary objects of my invention is to provide a padding rack which will be durable and efiicient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

Another salient object of my invention is to provide a padding rack embodying top and bottom compression plates between which sheets are stacked in alignment with means for engaging the opposite sides of the stack and for uniting the plates together and for normally urging the plates toward one another, the device permitting the gluing of one side of the stack and the handling and the laying aside of the stack until the glue has set.

A further important object of my invention is to provide a padding rack embodying a base plate carrying springs and locking straps for receiving the stack of sheets and a top compression plate for engaging the upper end of the stack having novel means for receiving and holding the straps in a desired, set, adjusted position with the springs under the desired tension;

With these and other objects in View, the-inin the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a side elevational view of my padding rack showing the same in use, parts of the figure being shown broken away and in section.

Figure 2 is a front elevational view of my padding rack showing the same in use, parts of the figure being shown in section, the part in section being taken substantially on the line 2-2 of Figure 3, looking in the direction of the arrows.

Figure 3 is a horizontal, sectional view taken onthe line 3--3 of Figure 2, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter R generally indicates my novel padding rack and the same includes a pair of like compression plates 5 and 6. These plates can be formed from any desired material, such as wood, composition, or the like, and can be of any desired size and shape suitable for receiving a stack of paper sheets 1 therebetween.

The plate 5 has pivotally connected thereto coil springs 8 on the opposite sides thereof. As

1 Claim. (Cl. 11-1) illustrated, the plate 5 carries staples or eyes 9 and the springs 8 are hooked through said eyes. The opposite ends of the springs have hooked thereto the rigid adjustment straps I0. The straps II] are provided with spaced openings H, the purpose of which will later appear.

The plate 6 has its opposite sides slotted as at l2 for receiving the straps l0, and the slots are so disposed and are of such a. size as to embrace the straps and hold the straps against lateral shifting. Openings 13 are formed in the front edge of the plate 6, and these openings bisect the slots 12 and detachably receive latch pins I4. The latch pins are each connected by a short length of chain I5 to the plate 6, so as to prevent loss of these pins.

In use of my novel padding rack, the sheets are stacked one upon the other with one edge thereof in the same plane, and after the sheets are placed in position, the plates 5 and 6 are placed over the stack. The straps Ill are then inserted in the slots [2, and the straps are pulled to place the springs 8 under tension after which the latch pins are inserted in the openings [3 and through selected openings II. This will hold the stack of sheets under compression, and one side of the sheets can be coated with the desired adhesive. The padding rack R. with the sheets can now be placed and moved to the desired point until the adhesive has dried.

Changes in details may be made without departing from the spirit or the scope of this invention, but what I claim as new is:

A padding rack comprising a pair of compression plates for receiving a stack of sheets therebetween, tension coil springs pivotally carried by one plate, the other plate having slots in the side edges thereof, and keeper openings bisecting said slots, rigid straps carried by the said springs adapted to snugly fit in the slots, said straps having a series of adjustment openings therein for selective alignment with the keeper openings, and keeper pins loosely carried by the plate having the slots and keeper openings,

said pins being removably fitted in the keeper openings for engaging selected openings in the straps.
