Description

"'NITED STATES PATE1\TT OFFICH CHARLES HOAG, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN LINE-FASTENERS.
Specification forming part of Letters Patent No. 180,343, dated July 25, 1876; application filed April 29, 1876.
T0 all whom t may concern Be it known that I, CHARLES HOAG, of Chicago, in the county of Cook and State of Illinois, have inrented a new and valuable Improvement in Clothes-Line Holders; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had tothe annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of a front elevation of my line-holder, and Fig. 2 is a longitudinal vertical sectional view thereof.
This invention has relation to clothes-line holders and the nature of my invention consists in a plate, which is constructed with tubular hearings, adapted to receive and afiord support for a serrated griping-dog and a halfsheave, and which is also constructed With an annular elevation, that forms, with a concavity in the periphery of the sheave, a channel, which is adapted to receive the clothesline, and-prevent the same from binding in the joint.
.In the annexed drawings, A desiguates a plate, which I prefer to make of malleable iron, of skeleton-form, and which is constructed with thimbles or tubular beariugs a a. To the thimhle or upper bearing a is pvoted a serrated dog, B, and which is held in place by means of a screw, o. By these means the dog is allowed to vibrate freely about its tubular post a. C designates a sheave, which rotates about the lower bearin g a, and is held in place on said bearing by means of a screw, e, and a washer, e. This sheave has a concave periphery, and represents one-halfof an annulargrooved pulley; It impinges against an annular elevation, f, forfned on the plate A.
It will be observed, from the above description that, when the clothes-line is drawn into the bite between the dog and the sheave, the annular elevation of the plate A will throw it upon the oonoave portion of said sheave, and prevent it from binding in the joint.
I am aware that a clothes-line holder having a cam, a lever,-a connecting-bar, and pulley, as-shown inLetters Patent granted to H. 0gborn, dated Iul5* 6,l869,nnmbered 92,206, has heretofore been employed, and I therefore lay no claim to said invention.
What I claiuas new, and desire to secure by Letters Patent,is
In a clothes-line holder, the plate A, having the annular elevation f and tubular bearings a a, in combination With the serrated dog B and half-rotary sheave C, all constructed and operating in the manner and for the purpose set forth.
In testimony that I claim the above I have hereunto subscribcd my name in the presence of two witnesses.
CHARLES HOAG.
