Application filed November 18, 1909. Serial No. 528,777.

for use in connection with sand paper sheets,

the same being efficient in operation to securely hold a strip or strips of sand paper in a manner which will render it convenient for the carpenter to work the sand paper over the surface to be dressed. With this and other. objects in view as will more fully appear as the description roceeds, the invention consists, essentially, in a sand paper block so formed as to constitute an easy and convenient hand-hold and provided with spring clamps that are designed to securely engage the ends of a sniper strips of sand paper, while at the same time the lower fiat face of the block forms a proper backingforsaid strips,'and the invention also consists in certain constructions and arrangements of the parts that I shall hereinafter fully describe and claim. I

For a full understanding Or the invention, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a perspective yiew 'of a sand paper block em oodying my invention; Fig. 2 is a longitudinal sectional view thereor; and, Fig. 3 is a perspective view of one of the clasps. V v

- Corresponding Li lCl like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

My improved sand paper holder comprises a block 1 which may be formed of any de sired substance or material, either solid or holl w, (the former in the present instance} and which may be 015 any desired shape or design, although preferably being formed with finger and thumb grooves 12 at opposite sidesand a flat palm rest 3, the, upper surface of said block preferably tapering from said palm rest, whereby to form proper engagement'surfacesfor, say, the fore-finger the sand paper strip 5,

of the operators hand when the device is held therein. ii

The lower face of the block 1 is preferably plane or fiat, as indicated at 4, and a 6i! strip of sand paper, as indicated at 5, is designed to be applied to such face, the ends of the strip being turned up into engagement with the ends of the block and held at such points by clamping plates 6. These plates are hinged at their upper edges t0 the ends of the block, as by staples or the like, as clearly illustrated in the drawing, and they are formed on their inner faces and preferably at'their lower edges with roughened or serrated surfaces 7, whereby they may be more securely engaged and'hold the ends ot' In order to hold these clamping plates 6 in firm engagement with the ends of the sand paper strip 5,

the block 1 is formed with a longitudinal bore 8 and a coil spring9 is mounted in said bore. Hooks 10 are secured to the ends of the contractile spring 9 andare intended for engagement in eyes 1i which are secured in Q the respective clamping plates 6. in the preterred construct on, the ends of the eyes 11 are passed outwardly through openings formed in the respectiveclamping plates 6 and are engaged or bent outwardly against the outer faces of the plates, as shown.

The releasing means for the plates'ti in the v present embodiment of my invention com prises handles 12 formed at their free ends with finger pieces 13 and lying in recesses 1% formed in the upper face of the block 1. These handles 12 are formed with angularly disposed outer ends 15 which are secured to the upper edges of the respective clamping plates 6 by screw bolts and nuts or similar 9 fastening devices and the lower extremities of these angularly disposed port-ions 15 of 1 the handles are iormed with apertures 16 through which the respective eyes 11 extend,

said eyes thereby serving the function of fastening devices for the handles as well as keepers or engaging devices for the hooks or" the contractile spring9. Obviously, the inner ends of the recesses 14 are enlarged, as

indicated at to accommodate the finger pieces 13 of the handle. I

From the foregoing description in connection with the accompanying drawing, the 7 operation of my improved 4 sand. paper holder will be apparent.-

number of stripsof sand paper, as 5, are

In the practical use of the device, one or any other desired applied to the face at of the block 1, their ends being slipped in between the roughened faces of the clamping plates (3 and the ends or" the block, the finger pieces 13 being tapered so as to swing the plates outwardly to permit of, this insertion and being then released, whereupon the plates will securely clamp the strip or strips and the parts will be thus assembled in readiness for the surface dressing operation. When one strip has become worn out it may be readily replaced by another or removed and the next strip underneath used. if the strips be superposed one upon the other on the holder. It will be seen that. I have provided a very simple, durable and etlicient construction of sand paper holder which is composed of con1paratively few parts that may be cheaply manufactured and easily assembled and which will nhti be liable to get out of order.

Vhile the accompanying drawing illustrates one embodiment of my invention, it is to be understood that my invention is not limited thereto, but that 'arious changes may be made in the construction, arrangement and proportions of the parts without departing from the scope of the invention as defined in the appended claims.

Having thus described the in cntioinwhat is claimed new is:

1. A sand paper holder, comprising a block, clamping plates hingedly connected to the ends of said block, the block being formed with a longitudinal bore extending thcrethrough, and a contractile spring located in said here and connected to said plates.

2. A sand paper holder, com 'irising a block formed with a longitudinal bore a spring mounted in said bore, clamping plates hingedly connected to the ends of said block eyes secured to said plates and projecting inwardlytherefrom, hooks connecting the spring to the eyes of the respective plates, and releasing handles, said handles being formed with angular portions, the extremities of which are provided with apertures through which the eyes pass, as and For the purpose set forth. I

In testimony whereof I atiiy my signature in presence. of two witnesses.
