(No Model.) Y O. W. BOMAN. RUBBER TI]? ATTACHMENT FOR PENGILS 0R OTHER-ARTICLES. .No. 368,509. Patented Aug. 16, 1887.
ll'iNiTnn TATE OLAES WM. BOMAN, OF NEW YORK, N. Y., ASSIGNOR TO THE EAGLE PENCIL COMPANY, OF SAME PLACE.
RUBBER-TIP ATTACHMENT FOR PENCILS AND OTHER ARTICLES.
SPECIFICATION forming part of Letters Patent No. 368,509, dated August 16, 1887.
Application filed J uno 30, 1-987.
characterized by rubbergrasping jaws and jaws or a tube to receive the end of the pencil or like article to which the attachment may be applied,in combination with a clamping-sleeve distinct and separate from both sets of jaws and encircling the rubber-grasping jaws, said sleeve and last-named jaws being provided the one with projections and the other with openings or recesses, whereby the bite of the jaws upon the rubber can be relaxed or tightened, according as the said projections are in or out of register with said openings or recesses.
The rubber-grasping jaws are formed in one with the split tube or jaws in which the end of the pencil is received.
The nature of my improvement will be readily understood by reference to the accompanying drawings, in which- Figure 1 is a perspective View of the two parts of the device separated from each other. Fig. 2 is alongitudinal axial section of the device provided with a rubber block and fitted to the end of a pencil.
The jaw portion'A of the device is struck up from a properlyshaped blank of sheet brass or other suitable metal to form the split tube a, which fits upon the end of the pencil P, the serrated jaws proper, b, and the cylindrical neck a, which is the seat for the rotatable clamping ring or sleeve B. This ring is held from longitudinal movement by any suitable means-in this instance by the projecting edges of the rubber block R on one side and l on the other side by the shoulder d, which lat ter also serves to limit the extent to which the Serial No. 242,079. (No model.)
comprises the shanks of the jaws, and on each of these shanks is an external swell or protuberance, e. In the clamping ring or sleeve B are corresponding openings, f. When the sleeve is rotated to bring its openings into register with the protuberances e, the latter enter said openings, and thus by allowing the jaws to spread apart loosen their grasp upon the rubber. When, however, the sleeve is turned so as to remove the openings from over the protuberances e, the latter are pressed upon by the sleeve, and consequently cause the jaws to close and tighten their hold upon the rubber.
I do not broadly claim the combination, in a rubber-tip attachment for pencils and the like, of rubber-grasping jaws with an encircling sleeve, the two being rotatable with relation to each other, and provided the one with swells or protuberances and the other with openings or recesses, which may be brought into or out of register with said swells by rotating the one part in or upon the other; but,
Having described my improvement and the best way known to me of carrying the same into effect, what I claim as new and of my own invention is-- A rubber-tip attachment for pencils and like'articles, comprising jaws or a tube to receive the end of the pencil formed in one with rubber-grasping jaws, and a clamping sleeve or ring encircling and rotatable upon the lastmentioned jaws, said rubbergrasping jaws and sleeve being provided the one with openings or recesses and the other with swells or protuberances, which may be brought into and out of register with said openings or recesses by turning the sleeve, substantially as and for the purposes hereinbefore set forth.
In testimony whereof I have hereunto set my hand this 13th day of June, A. D. 1887.
