DRIVING-CABLE.

. SPECFICATION forming part of Letters Patent No. 734,068, dated July 21, 1903.

Application filed July 16, 1902.

To all whom it may concern.-

Beit known that I, GEORGE S. INGLE, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Driving-Cable, of which the'following is a specification.

The present invention relates to drivingcables; and the object thereof is to provide a structure thatcan be both easily and cheaply constructed and is very strong, yet sufliciently yielding and pliable to permit its passage around sheave-pulleys Without straining or injuring it.

While the invention was devised with especial reference to haulage mechanism in coal-mines and similar stations, it will be evident that it is capable ot' use in various places where belts and driving-chains are now commonly employed.

The preferred embodimentot the invention is fully shown in the accompanying drawings and described in the following specification, though it will be evident upon an inspection ot the claims hereto appended that the structure shown is open to various changes and modifications.

In the drawings, Figure l is a side elevation of one form of construction. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a cross-section taken on the line X X of Fig. 2. Fig. 4 is a detail perspective view of one of the caps. Fig. 5 is a longitudinal sectional -view of a slightly-different form ot construction. A

Similar numerals of reference designate corresponding parts in all the figures ofthe d rawings.

In the practical embodiment of the invention a cable lO is employed, which can beconstructed of a single piece or several sections 4and may be in the form of a rope or chain,

though in the embodiment illustrated a Wire cable is employed. A plurality of spaced abutments 1l are arranged upon the cable at Serial No. 115,825. (No model.)

the cable. Caps 13 are fitted in the ends of the sleeve, said caps being in the form of collars, having openings I4 therein through which the cable passes. The openings are centrally arranged and taper toward their inner ends, the diameter of said inner ends being equal to the diameter of the cable, while the walls are preferably rounded, as clearly shown in Fig. 2. The collars, furthermore, have outstanding lianges l5, which abut against the ends of the sleeve l2 and are of equal thickness therewith. The caps are held in place by rivets 16, passed through the ends of the sleeve andsaid raps on opposite sides of the cable. The space or chamber formed between the sleeve and the cable is filled with suitable material, as 17, preferably Babbitt metal, that engages both the cable and the sleeve to hold them against relative movement. It furthermore bears against the inner ends of the'caps, which constitute stopshoulders for this purpose. This metal is cast within the sleeve, and to this end said `sleeve is provided with openings 18, arranged in opposite portions, through which the metal is poured, said metal filling the openings and forming l ugs 1),.that interlock with the sleeve. The portions of the metal surrounding the cable will engage in the grooves formed by the adjacent twisted strands of the same, and thus said metal Will positively tie the two elements against relative movement.

In the embodiment of the invention illustrated in Fig. 5 the construction is very similar, except that the caps in this instance are constructed integral with the sleeve, or, in

other words, the bore'at the ends of said constructed of one piece, though theother isv entirely practicable and may be advantageously employed, as sections of .ordinary pipe, otherwise valueless, can be utilized. As a result of this construction a power or driving cable is provided which can be manufactured at small cost and is very strong,

though sufficiently pliable to pass around sprocket-wheels or sheave-pulleys. Vhile the distance between the adjacent ends of the abutmeuts is comparatively small, the free portions of the cable are comparatively long, as said portions extend from the inner end of one cap to the inner end of the adjacent cap. This advantage will be apparent when it is considered that in these haulagecables as now constructed the distance from the center of one joint to the center of the next joint is twelve inches, while the distance between the adjacent ends of the abutments is two inches. The thickness of each cap is one inch, and therefore the exposed or free portion of the cable that can be bent at each joint is four inches, or double the distance between the abutments. rlhis length of four inches will permit a wire cable having a diameter of one inch to pass around an ordi nary-sized sheave without straining it to any appreciable extent.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a cable, of a sleeve surrounding the cable, and afilling interposed between the sleeve and cable and engaging both to hold them against relative movement, said filling terminating short of the ends of the sleeve to permit lateral movement of the cable in said ends.

2. The combination with a cable, of an abutment having a bore through which the cable passes, the intermediate portion of the bore having a greater diameter than the diameter of the cable, the end portions of said bore being contracted to form interior annular shoulders, and a metallic filling cast within the enlarged portion of the bore and engaging the abutment and the cable.

3. The combination with acable, of a sleeve surrounding the cable and having a bore of greater diameter than the same, a cap fitted in one end of the sleeve and surrounding the cable, and a metallic filling cast within the sleeve and engaging it and the cable.

4. The combination with a cable, of a sleeve surrounding the cable and having a bore of greater diameter than the same, a cap fitted in one end of the sleeve and projecting beyond the same toL form a bearing, and a tilling interposed between the sleeve and the cable.

5. The combination witha cable, of a sleeve surrounding the cable and having a bore of greater diameter than the same, a cap fitted in one end of the sleeve and projecting beyond the same to form a bearing, said projecting end having a flange that abuts against the end ofy the sleeve, and a filling arrangedv in one end of the sleeve and projecting beyond the same to form a bearing, said cap being provided with a central opening that tapers toward its inner end and through which the cable passes.

8. The combination with acable, Otan abutment having a bore through which the cable passes, the intermediate portion of the bore having a greater diameter than the diameter of the cable, the end portions of said bore being contracted to substantially the diameter of the cable forming shoulders, and filling arranged in the enlarged portion of the bore and abutting against. the shoulders thus formed.

9. The combination with a cable, of an abutment having a bore through which the cable passes, the intermediate portion of the bore having a greater diameter than the diameter of the cable, the end portions of said bore being contracted to substantially the diameter of the cable, and a metallic filling cast in the enlarged portion of the bore and terminating at the reduced portions thereof, the terminals of said bore being flared to the ends of the abutment, and the walls thereof being free of the cable.

10. The combination with an abutment having an enlarged interior bore and reduced oppositely-arranged openings leading from the ends of the bore, a cable passing through the abutment, and a metallic filling cast Within the bore and engaging the cable and the abutment.

11. The combination with a cable,ofa sleeve surrounding the cable, caps fitted in the opposite ends of the sleeve, and a filling arranged within the sleeve between the caps, said lling engaging the cable.

12. The combination with a cable,of a sleeve surrounding the cable, caps fitted in the 4opposite ends of the sleeve, rivets passing through the sleeve and caps, and a filling arranged within the sleeve between the caps and engaging the cable.

In testimony that I claim the foregoing as my own I have hereto afixed my signature in the presence of two witnesses.

GEORGE S. INGLE.
