L. F. M CARTHY SUPPORT OR STAND FOR STATIONERY" Original Filed July 5, 1928 Patented Jan. 12, 1932 Lno izl iuctmnfrrrY' or!rHrLAmanrrrm, PENNSYLVANIA p FSU PPOBj'l on swam) son STATIONERY Application filed July 3, 1928, Serial No. 290,140. Renewed November 21, 1930..

\The invention relates to devices intended t-ohold many sheets of stationery which are to be removed one sheet at atime.

The purpose of myinventionis to reduce the friction bet-ween the front sheet and the front holding mechanism by a spring-pressed roller.

A further purpose is to provide for manufacture of the frame for a single holder conveniently and cheaply from sheet material.

A further purpose is tofacilitate application of a number of holders for stationery to a single base or frame.

Further purposes will appear in the specification and in the claims. V

I have preferred to show but one general form with a slight variation to accommodate an additional holder for a second group of sheets of stationery, selecting a form which is practical, efficient, convenient and inexpensive and which at the same time well illustrates the principles of my invention.

Figure l is a perspective View showing the single holder form.

Figure 2 is a top plan view of theform shown in Figure 1.

Figure 3 is a section taken upon line 33 of Figure 2.

Figure 4 1s a. perspective showing two holding devices upon a single base.

Figures 5 and 6 are fragmentary sections corresponding generally in positlon with Figure 3 but showing slight. modification of the form shown. V

In .many locations where a number of cards, forms, slips or sheets of stationery of any character, all herein regarded as sheets, are to be held for copying, successive display or dispensing, it isdesirable to hold the entire pack, set or lot together initially and remove them'one at a time from the front. Each sheet in turn becomes the front. My inv vention is designed'to serve this purpose simply, conveniently and effectively. A'few of the uses are, upon or beside typewriters to hold cards for copying and upon desks or tables, in windows,'etc. where cards, forms,

- etc. are to be displayed or dispensed.

In all of these locations and uses, easy removal of the front card, slip or sheet of stationery with reliable retention of'the others until it is desirable to remove them, one at a time, are important. v v

y The base 5 is made of a plate of sheetmaterial bent upwardly and backwardly along parsQ sTA Es ATENT OFFICE the line 6 to providev a baok 7 and havingearsr 8 reversely bent from the sheet at 9 to support and guide the pins 10 which pivotroller in slots 12 but are drawn resiliently toward the back by spring 13 engaging-the fixed ears 14 at one end ofeaeh and their other ends are folded or bent forwardly, leaving. a corresponding opening for the rest whiehopening 1 comes preferably but not necessarily along a 1 line 19 in line with bend 6. J

The inward curve 20 in the rear edge of the base nearly corresponds with the upwardly projecting central edge 2l of theba-ck to fit '11. The pins. are adapted to move laterally withinthis curve in the uncut sheet, en

hlibllllgifl, larger number of. the strands or supportsto be cut from a given length of sheet material than would otherwise be the case.

{The weight of the sheets extending wardly at an angle tends to hold thesheets in the position shown inFigure 1 and resists the tendency ofthe adjoining. sheetst o fol: low the withdrawal movement ofthe front sheets :At the sametimeithe frictional-resistanceagainstthe backof the front sheet tending to prevent its withdrawal is greatly reduced by the use of the roller and by en gagement of the roller with the lower ends of the sheets. The spring tension upon; the

roller 11 is substantially uniform, no matter what the number of sheets withinthe holder. he structure in Figure 4 isidentical vwith that shown in the other figures except that the base is extended farenough for reception of a secondback 7, rest 17 roller'll and set of connections for resiliently mounting the roller in position. They are fastened upon the base through the. rest. Obviously the number of these additional backs is depend- The roll front support at the bottom of the set of sheets ofiers very little resistance to withdrawal of the front sheet. The friction of the back of the front sheet against the front of the next sheet is considerably greater and has a tendency to withdraw the other sheets with the front sheet. his tendency is offset by the friction of the backs of adjoining sheets against the front faces of the next sheets and finally against the back 7. The weight of the entire set or group resists withdrawal and this retention of the remainder of the set or group may be assisted by various means.

In the second back of the Figure 4 form I have shown a slight roughening of the lower part of the back immediately above the roll as at 22. This roughening can be obtained in any of a great number of ways, of which I have suggested one in the downwardly directed sharp projections shown at 22. These must be sufficiently sharp to tear the back of the adjoining sheet and are less likely to have this effect if they be not eX- tended down as far as the level of the roller. Another way of assisting in the retention of the remaining sheets in front of the plane of the lower part of the back is by bringing the top of the back forward far enough to necessitate or encourage the pulling forward of the front sheet slightly as it is withdrawn or to mechanically spring the remaining sheets forward so as to bring additional pres- Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a holder for sheets, a base, a back bent upwardly and rearwardly from the front edges of the base, slotted ears forwardly projecting from the ends of the back, a rest forwardly projecting at the lower end of the back, a roller across the front of the back above the rest, pivots for the roller extending through the slots of the ears and springs fixed at one end each and engaging the pivots to resiliently press the roller toward the back.

2. In a holder for sheets, a base, a back for the sheets extending upwardly from the base and terminating in forwardly extending slotted ears and a spring-pressed holder for engaging the lower part of the front of the sheets and guided within the slots in the ears.

sure between the back of one sheet and the front of the next throughout the set or group. Though abrupt forward turning of the back of the top above the groups or sets of sheets would serve one of these purposes I prefer to turn the back forward gradually as at 7 in Figure 5 because it performs both of the functions. It so far prevents easy withdrawal of the sheets without pulling them forward as to encourage if not require the bending forward of the front sheet as it is withdrawn and at the same time brings pressure to bear upon the upper parts of the sheets as to increase the friction between the sheets that are left.

In the form shown in Figure 6 I have firmly attached a friction-producing surface far as they fall Within the reasonable spirit and scope of my invention.
