sPEcIrIcATIoN forming part ofrneaes raient No. 738,684," daten september s, 190e. Application met July 17,1902. serial No. 115.997. (No man.)

.To all whom/,it may concern:

Be it known that I, GEORGE S. INGLE, a citizen of theUnited States, residing at Indianapolis, in the county of Marion and State of YIndiana,have invented a new and useful Driv-i ing-Belt', of which the following is a specification. y

This invention'relates to driving-belts of that class employed in transmitting power Various embodiments of the invention are`l illustrated in the accompanyingidrawings Aand described in the following speciiication,

and itwill be seen upon an inspection of the claims heretoappended that the invention is open to changes and modifications. It willl also be observed that features are embodied in the present case whichu are illustrated and claimed in a copending application iiled by me on July 16, 1902, serial No. II 5,825,101@ no` claim is made herein to any of these features.

In the drawings, Figure 1 is a top plan view `of a portion of a driving-belt constructed in accordance with the present invention.` Fig. 2 is a horizontal sectional view through a portion of the same. Fig. 3 is a vertical longitudinal section. Fig. 4 is a transversefsection taken on the line 4 4 of Fig. 42. Fig.` 5 is a similar section taken on the line of Fig.

2. Figs. 6 and 7 are also transverse sectional i views taken, respectively, on the lines 6 6 and employed for shortening and lengthening the belt. Fig. 9 is a detail sectional View through y, portion of the above-mentioned means. Fig.

l0 is a cross-sectional view more clearly illus-` trating the guides for the belt. Fig. l1 is a detail sectional view of a portion of the beltadjusting means.

Similar numerals of reference designate corresponding parts in all the gures of the drawings.

In the embodiment of the invention as shown a pair of continuous cables 10 are employed, preferably though not necessarily constructed of wire rope and arranged in parallel relation. These cables are connected at suitable intervals by abutments 11, preferably in the form of metallic blocks having long'itudinal parallel bores therethrough through which the cable passes. These bores each have an intermediate portion 12 of larger diameter than the diameters of the cables, while the end portions of said bores are contracted, as shownat 13, to the size of the cables, which therefore snuglypass through the same. The terminals 14 of the bores, however, are flared, as shown. The intermediate enlarged portions 12 are iilled with suitable metal (preferably babbitt) 15, which is poured while in a molten state through openings 16, formed in the walls of the abutments, said babbitt filling said openings and forming lugs 17, which interlock with the abutments. The metal also interlocks with the cables, and thus said abutments are held against relative movement upon the cables. The advantages for the particular construction of the bores with their Iiaring ends and the filling of metal has been fully explained in the above-mentioned application` and it is believed to be unnecessary to reiterate it in this specification.

Between the various abutments 11 each cae ble is surrounded and inclosed by a sleeve 18, said sleeves being entirely independent of each other and having their ends spaced a slight distance from the adjacent ends of the abutment. The bores through these sleeves are constructed exactly the 'same as those above described, and indeed the sleeves are similar in all respects to those set `forth in the copending application." Theyconstitute protecting devices for the "cablesA and being spaced apart in the manner shown do not interfere with the insertion of the teeth bca of use for various purposes, but in Figs. 8 to 11, inclusive, there is shown a structure `designed especially for hauling cars in coal and other mines. vIn this structure guideways 19 are' formed on opposite sides of the belt by means of spaced sets of strips 20, and outstanding fingers 2l, carried by certain of the abutments, project into and are movable in said guideways. These fingers preferably extend entirely across and embrace the abutment, being welded or otherwise secured in place. An upright stem or standard 22, also carried by the abutment, passes through the same and through the fingers, thus securely fastening them together. This standard is arranged to engage a car, which is thus carried along with the belt.

In order to slacken and tighten the cable as may be necessary the following mechanism is employed: The terminals of each cable are iitted in socketed heads 23, being held in place byBabbitt metal 24, poured therein and said heads are arranged in opposing relation. They are connected by turnbuckles comprising threaded shanks 25, having eyes 26 at their outer ends through which are passed pins 27, that are fastened to the heads. The shanks in turn are connected by the buckles 28, so that by turning said buckles the ends of the cables may be drawn toward each other. This mechanism takes the place of one of the abutments, and it is therefore necessary to provide bearings for the teeth of the sprocketwheels. These bearings are shown in the form of metallic plates 29,' which are located in rear of the heads 23 and extend across the space between the cables, as shown in Fig. 8p

It will be apparent to those skilled in the art that this belt can be used with the Wellknown forms of sprocket-wheelsI the teeth of which pass between the cables and engage the ends of the abutments. The structure is exceedingly strong, and the amount of exposed cable is suficient to permit the belt passing around the sprocket-wheels without straining or injuring it. The cables do away with the necessity of pivoted joints, in which there is necessarily a great amount of wear, and, furthermore, they are protected to a great extent by the inclosed sleeves and abutments. The guiding mechanism employed serves to prevent twisting of the belt, so that the standards always maintain their upright positions, and thus their engagements with the cars are assured.

. From the foregoing it is thought that the construction, operation, and many advantages ofthe 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-

l. In a belt of the class described, the combination with an abutment having bores, the intermediate portions of which are enlarged, the end portions being flared, of cables passing through the bores of the abutment, and fillings of metal cast within the enlarged portions of the bores and engaging the cables, said cables being laterally movable in the iared ends of the bores.V

2. In a belt of the class described, the combination with longitudinally-disposed cables, of spaced abutments connecting the cables and extending across the same at separated points, and protecting devices located on each= cable between the abutments and leaving a other.,

bination with lon gitudinally-disposed cables, of spaced abutments connecting the cables at separated points, and separate spaced sleeves lsurrounding each cable between the abutments.
