v SHEET HOLDER.
I Application filed March 4., 1924. Serial No. 696,879.
The objects of my invention are to provide means adapted to enable the user of hold the same; to provide means adapted to enable a user of the device to quickly install thereon and remove therefrom the material intended for use; and to provide a sheet holder adapted to minimize the waste of such materials as may be used thereon.
My invention consists in providing a block having rounded ends and having a clasp secured adjacent each of said ends and on top of said block; in providing conveniently operated clasps each of which comprises a pair of spaced apart pointed pins extending outwardly and longitudinally of said block and having their ends adjacent one of said rounded ends; in providing a metal base plate between said pins andcombinedly fixed to said pins and said block; in providing a clamping frame comprising a pair of spaced apart rods extending longitudinally of said block and slightly curved outwardly and having their inner and outer ends bent inwardly and connected with spaced apart in-v ner and outer rods integral therewith and extending transversely of said block and means for linking said inner transverse rod of said frame with the inner ends of said pins; in providing a metal band connecting said longitudinal rods and slidablethereon and means for securing said clasp in closed position comprising an outwardly extending lug having an ear integral therewith and extending at right angles thereto, said lug fixed to said base plate and adapted to be engaged by said metal band.
My invention further consists in the parts and in the combination and arrangement of p t a herein Set f rth an cl im d.

In the preferred construction of my invention as illustrated I provide block 1 having rounded ends 1. At each end of the block is fixed a buckle or clasp 2 having a pair of equal distanced spaced apart pins 3 extending longitudinally of. said block and having points 4 projecting outwardly. The pins are secured in position bybase plate 5 having ends 6 bentthere-around and secured to the block by screws 7. For securely maintaining the pinsagainst movement relative to plate 5 I prefer to solder them to the plate.
Clamping frame 8 has spaced apart rods 9. curved outwardly from block 1 and extending longitudinally thereof and has inner and outer ends 10 and 11, respectively, bent downwardly and slightly inwardly. Rods 13 and 14 integral. with rods 9, respectively, connect ends 10-10 and 11-11 and extend transversely of block 1.
by forming the clamping frame from a single bar. Inner end 13 has lunged con- 18, respectively, bent around inner rod 13 of clamping frame 8 and connecting nection with rod15 extending transversely with rounded end l of block 1.
21 is then slid longitudinally inwardly and &
pins 3 may have suitable length for providing proper adjustment of outer rod 14 relative to points 4 of pins 3 when clasp 2 is in closed position.
Base plate 5 also has integral therewith lug 19 extending outwardly and having car 20 bent at right angles thereto and extending outwardly for the purpose of engaging metal band 21 looped around and connect ing longitudinal rods 9 thereby maintaining the clasp in closed position as shown in Figs. 1, 2, 3, 6 and 10.
Longitudinal rods 9 are curved outwardly to provide sufficient spring in clamping I frame 8 for the purpose of retaining outer 7 rod 14 in tension engagement with points 4 when the clamp is in, closed position.
The operation of the mechanism of my in vention is as follows:
Assume the clasp is in open position as shown in Fig. 1 and that it is desired to securea shoe polishing cloth thereto. One end 22 of cloth 23 is pierced by ends 4 of pins 3 whereafter clamping frame 8 is closed by first lowering outer rod 1 1 downwardly and in engagement with the cloth and beneath points at of the pins. Inner rod 13 of the clasp is then lowered in engagement with the block whereupon the lever action of connecting plate 16 connected to inner rod 13 integral with frame 8' and rod 15 integral with the inner endof pins 3, causes.
outer I'Od 14c of frame 8 to tightly grip the cloth and hold it securely in engagement Metal band in engagementwith' ear 20 of lug 19 the shy retaining inner rod 13 of the clasp against upward movement and locking the clasp in closed position, as shown in Fig. 10. The other end 24 of the strip of cloth 23 is then tightly drawn around the under side 25 of block 1 andplaced in position in the clasp fixed to the other end of the block by the same method asemployed' for securing end 22 mths clasp as described.
I have, therefore, invented an extremely.
simple, efficient, efiective economical: and serviceable device for the purposes intended;
An advantage of'my invention is; that a layer of cloth, sand paper or other similar material may be clamped thereon and the complete strip excepting the small portions at the end in engagement with the clasp may be utilized without waste. 7
The usual method of manually sanding surfaces is to place a strip of sand paper upon a rectangular block and hold the sides or ends of the sand paper against the sides of the block by. the use of the thumb and fingers. This operation is not only verytiresome but. also involves considerable waste of sand paper inasmuch as it is im possible to retain the. paper in close contact with the block and when sanding the surface the and paper sometimes becomes crumpled and broken thereby rendering the same unfit for use as well as producing a marred or rough surface on the article being sanded. It is then usually necessary to discard the strip of sand paper and substitute therefor a new piece.
By the use of my sheet holder many 1naterials may be securely held in position for various purposes. I
Another advantage of my invention is that my clasp is so constructed that it will securely retain materials of various width and without regard to the width of the clasp itself. v
My invention is capable of some modification without departing from its scope or spirit as defined in the claims.
VVhatI claim as new and desire to secure by Letters Patent is:'
