`TRACE.

,. Patented Oct. 23,1906.

Application filed November. 28, 1904:. `Serial No. 284,495.

To all whom it may concern:

Be it known that I, SHERMAN SHIsLER, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, State of Ohio, have invented a new and useful Improvement in Traces, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to ltraces forming part of shafteharnesses, its` object being to construct a trace which will be of reat strength and durability and economica in construction.

The invention consists of means hereinafter fully described, and particularly set forth in the claims.

The annexed drawing and the following description set forth in detail certain means embodying the invention, such disclosed means constituting but one of various forms in which the principle of the invention may be used.

In said annexed drawing the figure represents a trace embodying my invention, the same being shown as broken and one end being shown in elevation, the opposite end being shown in axial section with the exception of the center cable.

My improved trace consists of a central steel-wire cable A, to each end of which is secured a metal eye B B, the cable intermediate of such eye being covered by a rubber covering C. Each eye B has formed near its inner end a nipple t, formed with superficial corrugations b', said nipples being of a reduced cross-section whereby there are formed shoulders b2 in plane intersecting the cable-axis and the corrugations b being formed with sharp engaging faces on the sides directed toward such shoulders, as clearly shown in the drawing. An opening b3 in the body of the eye is made of conical form, as shown, and is formed in continuation of the bore b4, passing centrally through the nipple. The cable end passes through bore b4 into the conical opening b3, its strands being separated,so as to fill said opening, and the spaces between the strands being iilled with a suitable metal, such as solder. It will be seen that in this manner the cable is securely fixed to the eye. Molded and vulcanized upon the cable and: surrounding the nipple b is an integral rubber lcovering C, whose extremities respectively abut the shoulder b2, forming a Water-tight joint therewith and with the nipples b. The said covering is vpreferably made of uniform diameter, as shown, which should be great enough to bring the outer surface of the covering flush with that of the eye proper, It will thus be seen that the cable is thoroughly protected against any deterioration which may be 'effected by moisture. I have found that while it is not absolutely necessary to provide the corrugations b it is preferable, since by reason of their use the rubber covering is caused to more firmly and strictly adhere to and engage with the nip les t. The outer end of each eye is forme with a removable portion B', which is held in place by means of a rivet b5. This feature of the eye is, however, separately described and claimed in application for United States Letters Patent,

serial No. 223,514, filed september c, 1904,'

and need not hence be herein described.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the means herein disclosed, provided the means stated by any one of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention- 1. A trace consisting ofthe combination of a iiexible steel cable, a metal eye secured to each end of the latter, and formed with a reduced portion having an outer corrugated surface and forming a shoulder, the corrugations on each such surface being formed 'with sharp engaging faces on'the sides directed toward such shoulder; and a rubber covering molded upon said cable and reduced portion and abutting said shoulder; each eye provided with a conical opening in which the corresponding cable end is expanded and secured.

2. A trace comprising the combination of a flexible steel cable; a metal eye secured to each end of the same, each sucheye being provided with a projecting superiicially corrugated nipple of smaller cross-section than the eye proper so as to form a shoulder, said cable passing through such nipple and a rubber covering molded upon said cable and IOO Such 'nipple and abutting said shoulder, the l ed toward such shoulder; and a rubber covouter surface of said covering bein substanl tially flush With the outer surface o the main portion of said eye.

3. lA trace comprising the combination of a flexible steel cable; a metal eye secured to each end of the same, each such eye being provided With a projecting supercially corrugated nipple of smaller cross-section than the eye proper so as to form a shoulder, seidv cable passing throu h such nipple and the corrugetions on suc nipple being formed With sharp engaging faces on the sides directering molded upon said cable and such nipple i 5 and abutting said shoulder,y the outer surface of said covering being substantially flush With the outer surface of the main portion of said eye.

Signed by me this 12th day of November, 2o 1904.

SHERMAN SHISLER.
