CABLE CAR.

Application-med November 25, 1927. Serial No. 235,647.

An object of the 1nvent`on istoy provide a car truck having aipluralityof drumsy rotatably mounted thereon andl operated through a power plant carried bythe truck,l

and about which a stationary cable may be arranged with its ends anchoredV at -the opposite endof a railway and adapted through the frictional engagement of the cable with the drum to cause the forward or rearward movement of the car upon therotation of the drum. Y Y

A .further object is to provide brake beams for certain of the drums adapted t0 secure the same against rotation, the frictional engagement between the cable and the drum when idle rserving to retain thel car against movement. n u

A further object ofthe invention is to form a gear wheel integrally with each of the drums and arranged for engagement with each otherfor simultaneous rotation of the drums, said drums being arranged in a double row along different horizontal planes with thexcable carried thereupon, with the respective rows of drums mounted for rota tion in opposite direction, whereby through such arrangement to enable the positive frictional engagement between the cable and the drum for operating the car without any lost motion. p

. A still further object is to provide an apparatus of this character of simple and practical construction, strong and durable, ef-

icient and reliable in performance, rela-` tively inexpensive to manufacture and operate and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the special construction and combination of the various elements comprising the invention, reference being had to the accompanying drawings forming a part hereof, wherein Figure 1 is a top plan view, Y

Figure 2 is a view in side elevation,

Figure 3 is a vertical transverse sectional view and Figure 4 is a vertical transverse fragmentary sectional view through one end of the car showing one of the cable guide pulleys arranged at the end thereof. Y

Referring now to the drawings indetail, the invention comprises a car truck comprisor lum-A lis reversed. y t

The traction for the 'car is derived'through ing `a horizontallydisposed frame indicated at 5 4mounted uponl a pair of truckwheels 6 ateach end for travelling upon rails 7. Y

The yplatform lincludes a plurality of spaced ,parallel longitudinally extending.v ,frame members 8 disposed intermediate y.the sides thereof, thev upper edge of saidframe members forming a supportlfora plurality of bearing brackets 9 forrotatably mounting shafts 10 `extending transversely of the'- car and upon each of which cabledrums 11 are rotatably supported.l

The lower edges of the frame membersSi.

also provide means for attaching a plurality of bearing brackets 12 forming a mounting for a series of lower shafts 13 upon which drums 14 are rotatably carried.

At one side of each of the drums 11 and 14 are formed spur gear wheels 15, the gears of the upper and lower sets off drums being engaged for simultaneous Yoperation with each other. By this; arrangement .the upper.

row of drums are disposed for rotation in an opposite Ydirection from the lower row, of drums as illustrated by the directionv shown in Figure 2 of the drawings. Each of the upper shafts 10 `extend toward one4 side of i Y the car, the intermediate shaft havinga relatively enlargedgear '16.' keyed for .rotation therewith and constituting a.V .drive gearfor connection with apower plant of anysuitable character mounted on the car and by means of which the various gears and drums may be operated. v

The upperishafts 10 at each side of the center shaft are provided with brake drums 17 having brake bands 18 arranged thereabout in braking relation therewithV and operatively connected by brake rod 19`which is attached to a brake lever 20 mounted upon a support 21 disposed between the drums 17. As illustrated in Figure 2, the brake'rods 19 extend in opposite directions from the lever 20 and are attached at opposite'sides of the pivot 22 of the lever so that the movement of x the lever in one direction will operate the rods in opposite direction. j In order to enable the brake bands 18 to be applied simultaneously through the operation of the lever in a predetermined direction, the mounting of the brake band on the respective drums 17 -Y tending between a pair of horizontally disposed guide pulleys 24 mounted at each end of the car and then partially wound alternately about the upper and lower sets of drums. To accomplish the proper winding yof the cable about the drums in the manner indicated, the upper and lower sets f drums y drum and back around the second lower drum and so onthroughout the device until each of the drums are partially engaged by the Vcable in the manner indicated.

It will be apparent that upon winding the cable about the drums in the manner indicated and by creating` a .suitable tension upon the cable that a positive gripping action will occur between the cable and the drums resulting in the movement of the car in a predetermined direction upon the operation of the drums. Y

Y Furthermore upon the stopping of the drive means for the drum and applying the brakes through the lever the friction engagement between the drums and the cable will serve to retain the carin position against movement and thus enable the car to be held against movement even upon severe grades.- Cable cars constructed'in accordance with our invention are admirably adapted foruse in transporting logs, lumber and other heavy material over grades at a minimum cost of construction, maintenance and operation.

Itis obvious that the invention is susceptiblek of various changes Vand modifications, without departing from the spirit or scope of the invention or sacrificing any of its advantages, and we accordingly claim all such formsof the deviceto which we are entitled.'

Having thus described our invention, whaty we'claim as new is: Y v

1. In an apparatus of the class described, a vehicle having a plurality of horizontally disposed rows of drums rotatably mounted thereon and operatively connected with each other and the stationary cable wound about each of said drums.

2. In an apparatus of the class described7 awheeled vehicle,anupper and lower row of drums rotatably mounted thereon, gears attached to each of said drums and mounted forengagement with each other for simultaneous rotation, the upper row of drums being arranged for rotation in a directionop# posite from said lowerfrow of drums, one of saidv drums having a drive gear4 connected therewith, braking means operatively engageable with a pair of said upper drums and a stationaryy cable engaging each of said v drums. Y

8. In a cable car of the class described, a car platform, car wheels for the same,a plurality of cable drums rotatably mountedv upon the upper and lower edges of the platform and disposed in staggered relation with res' spect to each other, gear wheels formed on each of said drums, the upper gear being arranged for engagement with the lower gear for simultaneous rotation of the drum, said upper and lower drums being disposed for operative rotation, a drive gear connected with one of the upper drums, brake means operatively engageable with a pairof the upper drums, a stationary cable, cable guide pulleys mounted at each end of the car, said cable being arranged about said upper and lower drums in alternate arrangement.V

In testimony whereof we aiiix our signatures; l

CHARLES G. NOBLE. JAMES T. KING.
