CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 306,909, dated October 21, 1884.

Application filed May 17, 1834. (No model.)

To a/ZZ whom t may concern.-

Be it known that we, LEONARD B. Easines- 'roiv and PARCEL BRrNKnRHorr, citizens of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvementsin Cable Railways; and we do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l ofthe drawings isa side elevation of our invention; Fig. 2, a top plan View thereof, and Fig. 3 a longitudinal central section.

The present invention has relation to certain new and useful improvements in cable railways; and it consists in the details of construction, substantially as showniu the drawings, and hereinafter described and claimed.

ln the accompanying drawings, A represents the truck of a car, provided with the usual ilanged wheels, B, supported bythe rails a of the track. The rails c are connected in any suitable manner to the side stringers, b, which are supported by suitable posts, c` connected by braces d. rlhe truck'A has a grooved drum, C, rigidly secured to a transverse revolving or rotary shaft, e, receiving its motion by steam or other power, as found most convenient. A cable, D, passes around the drum C in the groove, the cable being brought down under the drum, the ends crossing each other, extending in opposite directions to the ends ofthe road and suitably fastened thereto.

At the ends of the truck A are groovcd pulleys E adj ustably connected thereto, over which passes the cable D, the vertical adjustment ofthe pulleys tightening the cable when the pulleys are raised, this being of importance when the cable becomes too loose to properly act in connection with the drum.

To the sides ofthe truck A, near each end, are securedhangers F, to the lower ends of which are journaled horizontal friction-rollers G, to bear against the sides of the stringers Z` and keep the truck from jumping the track.

lIt should be understood that the friction-rollers G have a vertical play or motion on the stringers.

hangers F, to adapt them to any up-and-down motion of the truck or any irregularities in the surface of the stringers, and thus prevent therollers from binding.

To the sides of the truck A are adj ustabl y x secured hangers H, of sufticient length to extend on a plane below that of the stringers b, the ends being bent at an angle inwardly under the stringers to forni journals for frictionrollers I, which vertically revolve, their peripheries bearing against the under side of the These rollers keep the truck in position when it attempts to j ump the track, and it should be understood that the peripheries of the rollers are only brought in contact with the stringers to revolve when the truck attempts to jump the track. The adjustment of the hangers is to adapt the rollers l to the varying widths of the stringers used.

Any suitable power may be used inimparting motion to the grooved drum, and the stringers may be supported by one or two posts at the ends, as found desirable, or any suitable frame-work may be substituted so long as the under side or edge of the stringers will be unobstructed to allow the rollers I to bear against it at any point along its length.

XVe are aware that it is not new to provide a car or ca-r-truck with a revolving groovcd drum and a rope or chain passing around the same, crossing at the under side thereof, and

extending in opposite directions over 'guidepulleys, so that as the drum revolves it will pull upon the rope or chain and form an immovable fulcrum to give motion to the truck.

lVe are further aware that car or car-trucks have been provided with guard-rollers to bear against the side and under edge of the stringers or tracks to prevent them from j umping` or leaving the track. lVe therefore do not wish to be understood as claiming, broadly, the construction above referred to 5 but,

Having fully described ourinvention, what we do claim as new, and desire to secure by Letters Patent, is-

l. In a cable railway, a suitable car-truck having at its ends verticallyadjustable pulleys and a grooved drum secured to a rotary shaft, in combination with a suitable cable, the same passing over the drum, crossing at the bottom thereof, and extending over the IOO adjustable pulleys, substantially as und for om, Substantially asnndfortho purposespooithe purpose set forth. fied.
