Jan. 24, 1939. w. L. WOLFORD SHEET HOLDING DEVICE Filed March 24, 1937 r/n-A/ Sta te Mire/*4. h alfara ATTORNEYS Patented Jan. 24, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to sheet holding devices and has for an object to provide a device of this character that will promote ease and rap-ichty of withdrawal and replenishing sheets, and will promote economies in filler costs by the elimination of perforations, stapling, and the like, while at the same time will hold the sheets in presentable form for writing thereon.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure l is a front elevation of a sheet holding device constructed in accordance with the invention and showing a pad of order sheets assembled therewith.

Figure 2 is a side elevation of the parts shown in Figure l.

Figure 3 is a cross sectional View taken on the line 3-3 of Figure 1.

Figure 4 is a detail view in elevation showing a pad of sheets particularly well adapted for use in connection with the sheet holder.

Figure 5 is a detail view in side elevation of the pad of sheets shown in Figure 4.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, the sheet holder is shown to comprise a substantially rectangular back plate l5 preferably formed of sheet metal and having lateral wings ll of the general shape shown in Figure 2 bent to extend parallel with each other at opposite longitudinal edges of the back plate adjacent to the top longitudinal edge of the back plate. The top of the plate is provided with a tab 12 which is bent forwardly to bridge the wings H at the upper edges of the wings and form a stop which butts against the upper end edges of sheets l3 assembled as a pad. The side edges of the sheets at the same time butt the wings ll so that the sheets are held assembled in a neat compact pad.

As best shown in Figure 2. slots M are formed in the Wings H at the upper end edges thereof and near the back plate [0, to produce resilient tongues 35 from which substantially semi-cylindrical ribs l6 are struck inwardly at about midway between the ends of the tongues. These ribs engage in correspondingly shaped notches ll formed in the side edges of the sheets. The purpose of the ribbed resilient tongues is to grip the sheets and reinforce the same against accidental dislodgment under severe conditions of service.

A leaf spring clamp N3 of the general shape shown in Figure 3 extends transversely across the back plate parallel with the end stop l2. One

. end IQ of the clamp is deformed to extend at an angle to the clamp and is clamped against the indented rib IB of one of the spring tongues l 5 by a plate 20 which extends longitudinally of the tongue and is secured at the ends to the tongue by screws 2|.

The pad of sheets I3 preferably is of the type disclosed in my co-pending application filed March 15, 1937, Serial No. 131,031 and entitled Strip gum padding so that in this application it will be merely stated that strips 22 of an adhesive medium are secured to the side edges of the sheets directly opposite toeach other and adjacent to the notches I! of the sheets. These strips assemble the sheets as a unit and maintain the sheets in presentable form so that to detach a sheet it is merely necessary to lift the sheet at an angle from the underlying sheets until the sheet is stripped from the adhesive medium 22 and then pull forwardly upon the detached sheet until it passes from underneath the leaf spring clamp l8.

From the above description it is thought that the construction and operation of the invention will be fully understood Without further explana-tion.

What is claimed is:

A writing pad holder comprising a base plate, wings on the longitudinal edges of the plate forming stops for engaging the edges of a pad which may be supported on the plate, there being slots formed in the wings at one end thereof adjacent to the plate to provide resilient tongues at the ends 'of the wings, and oppositely disposed locking ribs on the tongues adapted to be engaged in notches in the longitudinal edges of the pad for yieldably retaining the pad in place on the base plate.
