K. PARKE. ERASER HOLDER.

No. 407,607. Patented July 23, 1889.

KATE PARKE, OF CHICAGO, ILLINOIS.

ERASER-HOLDER.

SPECIFICATION forming part of Letters Patent No. 407,607, dated July 23, 1889.

Application filed April 13, 1889. Serial No. 307,138. (No model.)

To all whom it may concern:

Be it known that I, KATE PARKE, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and usef ul Improvements in Eraser-Holders, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates more particularly to an improved holder for rubber erasers and improved means whereby a suitable brush may be connected with said holder for con veniently removing from the surface of the paper the loose particles of rubber and paper incident to the use of the eraser.

To this end my invention consists in the various novel features of construction hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

Figure l is a plan view of the blank from which the holder will be formed. Fig. 2 is a plan View of the movable jaw-blank. Fig. 3 is a perspective View of my improved holder. Fig. 4 is a view in vertical section on line 4 4 of Fig. 3. Fig. 5 is a view in horizontal sec tion on line 5 5 of Fig. 4.. i

A designates the main body of the eraserholder, this body being formed of sheet metal cut, preferably, to form a blank having the portions aand a, that will constitute the sides of the holder, the portion a adapted, when properly folded, to form the top of the holder, and the portion o adapted to overlap the sides a and be suitably united thereto by solder or otherwise. The portion a of the blank from which the holder is to be formed is preferably out, as at ed, to form the division-plate (6 that will be turned downward and constitute the base of the socket Within which the butt of the brush B will be retained. I11 piece with the body A will be formed the extended fixed jaw A, which will cooperate with the movable jaw A as a means for clamping the rubber eraser C, and by preference the front edges of the jaws are serrated and inwardly bent to better grip the rubber. The movable jaw A is preferably formed with the inwardly-bent flanges a,

which will be pivotally connected to the sides a and a of the holder by means of a suitable pivot-bar D. This pivot-bar D by preference extends from side to side of the holder, and upon this bar is fixed a reaction-spring E, one end of which will bear against the rear portion of the movable clamp-jaw A while the opposite end of this spring will engage with the fixed portion of the holder.

It will be readily understood that the precise means for pivotally connecting the jaws of the holder may be varied, and any other suitable form of reaction-spring may be employed instead of that shown.

From the foregoing description it will be seen that in one end of the holder is formed a socket, within which may be fixed the brush B, this brush being held in place within thesocket in any convenient manner-as, for example, by indenting the surface of the metal or by suitable rivets. WVhen it is desired to insert a rubber eraser within the jaws of the holder, it is only necessary to depress the rear end of the movable clamp jaw A against the 7 5 force of the reaction-spring E, thereby causing the jaws to open to receive the rubber. When the pressure upon the rear end of the movable jaw is released, the reaction-spring E will cause the serrated ends of the jaws to firmly bind upon the rubber and securely hold it in place, while at the same time the side edges or walls of the jaws will guard the rubber against lateral movement while in use.

It will thus be seen that as the rubber be- 8 5 comes worn it can from time to time be projected from the jaws of the holder, and when exhausted a new rubber can be readily inserted in the jaws. It will be seen that by my present invention a simple, cheap, and ef- 9o fective means for clamping the rubber is secured, and at the same time a convenient means is providedfor holding a brush by which the particles of rubber and paper may be readily removed from the surface upon which the eraser has been used.

Having th us described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. An eraser-holder having a sheet-metal body out and bent to form a brush-socket in one end, and having a set of movable jaws at shown, to form upturned flanges, with an overlapping top and inturned end to e0nstitute a brush-socket, of the loose jaw having turned ears or lugs joined pivotally to said flanges of the base-plate and the coil-spring reacting to force the clam pi11g;j. uvs normally together, substantially as described.

KATE PARKE.
