ERASER HOLDER Filed May 31, 1930 ATTORNEY Patented June 30, 1931 UNITED STATES PATENT- OFFICE THOMAS H. JONES, F ROANOKE, VIRGINIA, ASSIGNOR OF'TWO-THIRDSTO PAUL B.

CULP, 011 ROANOKE, VIRGINIA mmsmz. rionmm Application filed May a1, 1931 Serial No. 458,747.

This invention relates to improvements in eraser holders and has as its primary object to provide a novel compact device for holding a pencil eraser and which devlce will be so constructed that the eraser may be replaced by a new one when it becomes too worn for further use.

Another object of the invention is to provide a holder for an eraser so constructed that the eraser will be very firmly and securely held in place sothat there will be no likel1- hood of the same being disarranged, when in use, nor any likelihood-of the eraser being separated from the holder. 1

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings, and specifically understood of course that minor changes may be made so long as they fall within the scope of the claim.

In describing my invention in detail, reference will be had tothe accompanying drawings, wherein like characters denote like or corresponding parts throughout the several Views, and in which:

Figure 1 is a View in side elevation of the holder embodying the invention, the component parts of the holder being illustrated in the positions which they will occupy when the eraser to be held is introduced into the device or is tobe removed therefrom.

Figure 2 is a longitudinal sectional view illustrating the relative positions assumed by the parts of the holder when the eraser is gripped by the holder.

Figure 3 is a view similar to Figure 2 illustrating a modification of the invention.

Figure 4: is a view in end elevation of the eraser holder, the same being in the condition shown in Figure 1, and the eraser being in place in one element of the holder.

'The holder embodying the invention comprises a pair of tubular members one of which is indicated by the numeral 1 and the other by the numeral 2, and these members are preferably of resilient sheet metal and of cylindrical form. The member 1 is telescopipointed out in the appended claim, it being embodiment ofthe invention shown in Figures 1 and 2 of the drawings, is closed at one end by a semi-spherical end portion3. The

member 1 at its other end is formed with longitudinal incisions 4 providing a plurality of clamping portions 5 which are so formed as to be relatively spread outwardly with respect to one another, and it is within the bounds of these members that the eraser, 0 0 which is indicated by the numeral 6, is to be fitted. v

The member 2 is of hollow cylindrical form and is slidable upon the member 1 and the member 1 is formed with two diametrically, I oppositely located and longitudinally extending slots 7 and headed studs 8 are mounted upon the inner side of the section 2, and in one position of sliding movement of the member 2 on the member 1 is limited and, in one position of sliding movement of the member 2, the clamping portions 5 will be relatively spread and, in the opposite or other position, the members will be constricted by the riding of one end of the member 2 over the said members, the elasticity of the eraser permitting of this inward shifting or dis placement of the said clamping portion and the eraser being in this manner securely gripped by the said portions. 30 In order that the eraser may be held with certainty within the bounds of the portions 5, each of the said portions is formed with a stamped out spur 9, which spur is directed inwardly so as to become embedded in the eraser 6 when the eraser is inserted into the respective end of the member 1. The embodiment shown in Figure 3 is identical with that shown in Figures 1, 2 and 4 of the drawings except that in place of the semi-cylindrical closed end 3 of the member 1, this end of the said member is formed with a hollow threaded socket 10 into which one end of a. lead pencil 11 may be threaded, the threads of the socket entering, of course, into the wood body of the pencil. Parts in this figure, corresponding to parts in Figures 1 and 2 are indicated by the same reference numerals, primed.

What I claim is:

An eraser holder comprising telescopic tubular members adapted to receive the eraser, the inner tubular member having incisions leading in from its end and dividing said end into eraser clamping portions, said inner member being provided at opposite sides with parallel slots, and studs attached to the outer tubular member and slidably received in the slots and having heads extending into the inner member, the parts being so arranged and proportioned that the outer tubular member holds the studs in contact with the eraser and contracts the clamping portions of the inner member against the sides ofthe eraser when the same is projected beyond the ends of both of the tubular members.

In testimony whereof I afiix my signature.

THOMAS H. JONES.
