W. SHEMPP. SANDPAPBR HOLDER.

69/14/66. mrmeyp" WILLIAM SHEMPP, OF
ATENT FFIQE.
BUFFALO, NEW YORK.
SAND-PAPER HOLDER.
SPECIFICATION forming part of Letters Fatent No. 470,794, dated March 15, 1892.
Application filed September 14, 1891. Serial No. 405,582. (No model.)
To all? whom it may concern:
Be it known that I, WILLIAM SHEMPP, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New the work has been heretofore employed, the
sand-paper being folded over the working edge of the block and held in place by the hand. While such a block is serviceable for the purpose, it can be used only in connection with the particular work to which its edge is conformed, so that different blocks are required for different styles of molding orother work.
The object of my invention is the produc tion of an adjustable backing block or holder whose working edge can be readily varied to fit the contour of moldings or other Woodwork of different designs, thus obviating the necessity of providing a separate backingblock for each kind of work.
In the accompanying drawings, Figure 1 is a perspective View of my improved holder. Fig. 2 is a longitudinal section thereof. Fig. 3 is a transverse central section of the same. Fig. 4 is a perspective view of a slightly-modified form of the holder. Fig. 5 is a longitudinal section of a modified form of such holder.
Like letters of reference refer to like parts in the several figures.
' The holder consists, essentially, of a number of thin plates or layers A, of any suitable material, which are i'novably clamped together side by side, so that the several plates or layers may be adjusted in the holder to cause their plain working edges to collectively conform to the surface to be smoothed or polished,and thus serve as a backing for a sheet of sand-paper. The layers A are preferably constructed of rubber or other flexible material, so as to form a yielding backing for the sand-paper placed over the same, and thereby cause the sand-paper to wear longer; The flexible layers are clamped between two boards or plates B by a screw or bolt 0 passing through transverse slots a, formed in the layers, and openings 1), formed in the clamping boards. The clamping-boards are narrower than the layers A, so that the longitudinal edges of the latter project beyond the boards. Sheets of pasteboard e are preferably interposed between the outermost layers A and the clamping-boards to stiffen such layers and prevent the same from being deflected outward under the pressure exerted upon the holder. F are retaining-strips connecting the ends of the clamping-boards B, and which hold the layers A against lengthwise displacement. Each retaining-strip is preferably secured at one end to one of the clamping-boards and extends over the adjacent end of the other board, the two strips overlapping each other and being provided in their lapped portions with longitudinal slots f, through which the clamping-bolt 0 passes. This construction permits the thickness of the block to be varied by inserting a greater or less number of layers between the clamping-boards. Theslots in the strips F permit the latter to be moved inwardly or outwardly in moving the clampingboards toward and from each other for increasing or reducing the thickness of the holder.
In adjusting the holder to molding or other wood-work the clamping-bolt O is loosened and the loose layers are firmly pressed against the surface to be polished, so as to cause the plain edges ofall of the layers to bear against the same, the edges of those layers which bear against the depressions of the work being projected, while those bearing against the elevations are caused to recede, as shown in Fig. 3, thus giving the laminated holder an irregular edge, which is the reversed counterpart of the work to be polished. The transverse slots of the layers permit the latter to slide upon each other in adjusting them. After adjusting the layers they are clamped in position by tightening the bolt 0. A sheet of sand-paper is then placed over the working edge of the holder and held against its sides,
as shown by dotted lines in Fig. 3. The holder thus forms ayielding backing for the sandpaper, whose edgeis readily adjusted to moldings or curved surfaces of various shapes. If the block is not desired to be adjustable with reference to its thickness, the ends of the clamping-boards B may be connected by short strips F, which extend only across the ends of the holder, as represented in Figs. 4.- and 5.
If desired, the fiat side of the clampingboard, in which the head of the connectingbolt 0 is seated, maybe used as abacking for polishing flat surfaces. For this purpose said facing g of rubber or other soft material.
Instead of being raised, as shown in Figs.
1, 2, and3, the thumb-nut of the clampinging material, consisting of anumber of plates or layers provided with transverse slots, boards between which the layers are arranged, a clamping-bolt connecting said boards, and retaining-strips secured to one of the boards and extending over the ends of the other board and providedin their adjacent ends with slots th rough which saidclamping-bolt passes, substantially as set forth.
bolt may be countersunk and bear against a dished plate I-I, securediu arecess in the adjacent clamping-board, as shown in Fig. 4. If preferred, the nut may be held against turning and the bolt be turned in the same in clamping the parts together, in which case the headof the bolt is nicked to receive a screw-driver, as represented in Fig. 5.
I claim as my invention- 1. A holder or backing-block for a sheet'of ber, 1891.
