CURVE FOR CABLE RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 396,054, dated January 8, 1889.

Application filed March '7, 1888.

To all 1071,0122, it may concern:

Be it known that 1, CHARLES L. SNYDER, of Kansas City, in the county of Jackson and State of Missouri, have invented certain new 5 and useful Improvements in Curves for'Cable Railways; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Hy invention relates to an improvement in cable-railway curves.

The object is to provide means for carrying both thecable and the grip around the curve without subjecting either to frictional wear. I

A further object is to provide carrying mechanism which shall be free from liability to get out of order and in which the wearing 2o friction of the movable parts shall be reduced to a minimum. lVith these ends in view my invention consists in certain features of construction and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the curve in perspective. Fig. 2 is partial top plan view. Fig.3 is a vertical transverse section 011 line 5c of Fig. 2. Fig. 4 is a vertical transverse section on line y y of Fig. 2. Fig. 5 is a detail view of one of the links, and Fig. 6 is a detail view of one of the end spindles and guide-plates.

A represents one of a series of skeleton brackets such as are commonly employed to I support the tracks and form a conduitfor the cable and its supporting-pulleys B. l The brackets herein shown are so arranged as to form a curve corresponding to an angle at the center of about ninety degrees, such as would be employed in turning from one street into another street at right angles thereto. My invention, however, contemplates curveturning mechanism equally well adapted to curves of all the different angles required.

The slot-irons are represented by a, between which is located the slot for the passage of the grip, as is usual.

The cable-supporting pulleys B are located at the base of the conduit, one at each end of Serial No. 266,406. (No model.)

the curve, as shown. Between the two supporting-pulleys B the cable C is supported in a curved position corresponding to the curved slot between the slot-irons by an endless carrier constructed and mounted as follows: An 5 5 endless series of travelers, each consisting of a pair of flanged wheels, D, secured to the ends of a vertical axle, (1,18 disposed along the inside portion of the curve, the travelers: being held against lateral displacement by curved tracks E E and E and E bolted or' otherwise secured to the brackets or to suitable supports attached to the brackets. The tracks E form an upper and a lower guide and support for the inner faces of the outer line of travelers, the annular flanges d of which overlap the upper edges of the said tracks, while the peripheries of the wheels of the travelers engage the outside faces of the tracks. The track E forms a lower guide and support for the outer line of travelers,. and is located along the outer faces of the lower wheels on the travelers. The tracks E form an upper and a lower guide and support for the inner faces of the inner line or returnline of travelers, and the track E an upper guide and support for the outer faces of the inner line of travelers.

In order to prevent any possible cramping at the ends of the advance and return lines of travelers, and at the same time to prevent any unnecessary frictional wear, a pair of traveler-carrying spindles, F, is journaled one at each end of the endless series of travelers, and provided with scalloped-edged disks f at their ends in position to receive the peripheries of the wheels of the travelers as they begin to sweep around from the advance. to the return line, or viceversa, each scallop f being constructed to receive and retain with a loose fit about one-third of the periphery of the. wheel and carry them around into position to engage the tracks on the other line. The tracks stop short just before they reach the end spindles.

The spindles F are journaled at their upper and lower ends in bridge-trees G, secured be-. tween two consecutive brackets, as shown, and provided with journal-boxes g, adapted to be adjusted lengthwise of the bridge-trees, 199

preferably in slots y, formed in the bridge trees.

The travelers are connected bylinksll, the central portions of which loosely embrace the axles of the travelers, the ends ol. two consecutive links being so connected as to admit of the links being turned freely in the plane of their longittulinal axes. The particular construction ot the hinge-joint between the links is immaterial, so that they are allowed the required flexibility. In the present instance one of two adjacent ends is bifurcated to admit the end ot the adjacent link, and the ends are perforated to receive a pintle to lock the parts together. The central pols tions of the links are provided on their outer faces with tlat seats It to receive the backs of bearing-blocks K, and are provided, further, with flanges 71, perforated to receive tastenings to secure the said blocks in position.

The blocks h are preferably made olj' wood, and their outer faces, /r, are intended to lie in a curved plane slightly inward ot the vertical plane of the slot between the slot irons, and the cable (I is intended to rest in extended contact with their outer t'accs.

As the travelers leave the ends ot a set of tracks and are carried around into position to engage the ends of the other set otf tracks, there is a slight tendency of the travelers to sag, so that the flange ot' the wheel ot' the traveler would be liable to enter behind the track instead of on its upper mlge, as is intended. In orderto el'tectually guard against any injurious results from such a tendency, a circular guide-plate, L, is provided. It; is preferably formed skeleton, as shown, to render it lighter, its radial arms Z being provided on their ends with upturned flanges I, through which the plate is secured to the lower face of the scallop-edged disk f at the lower end of the spindle l. The rim ot' the plate L projects beyond the et'lge ot' the disk fl and its upper side forms a rest t'orthc lower wheels on the travelers as they are being-carried around by the spindle l and delivers them without any possible displaccment with their flanges resting ontheuppcrcdges ot the tracks. As thus constructed the cable has an extended contact with each one of the Mocks K as they are presented along the curved track within the condnit,a-nd the bearlug-faces of the blocks and travelmrs to which they are attached are caused to travel along with the cable, the extended. bearing of the cable wit h the blocks ellectually preventing the least tendency of the cable toslide on the blocks, and hence the said bearitig-taces become essentially fixed relat ively to the cable.

It plain that thebloeks must; necessarily present their broad faces to the cable, since their connection with the links is rigid, while the axles of the travelers are free to rotatein their bearings in the links. Asthe grip comes along it in turn rests in contact with the faces of the blocks and is carried without anyslid- 111g friction whatever {dong the length of the endless carrier from one end spindle to the other. The wear on the pulleys (which in the ordinary construction are either very soon out through themselves or cut; the cable) is thus avoided, as well as the loss ol' powerand wear on, the grip caused bytheguarda'ail. As the travelers leave the cable and turn the end, and as they turn the opposite end to engage the cable, they are carried bodily by the end spindles and sulter no t'rictional wear.

It is evident thatthe travelers mightbe disconnected and held in position solely by the tracks and the meeting edgeot' the blocks jlv', and that numerous slight changes in the form and arrangcnni-nt ot' the several parts might be resorted to without departing .l'rom the spirit and scope of my invention, and hence I do not wish tolimitmyselt. strictly to the construction herein set forth; but,-

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

In a cable railway, the cotnbination, with a cable, of an endless carrier composed of a plurality of wheeled travelers lforcarrying the cable or grip, the cable or grip bearing faces ol? the travelers being substantially tixed in a plane parallel to the path ot the travelers, sub stantially as set lorth.
