STORE-SERVICE TRACK.

SPECIFICATION forming part of Letters Patent No. 355,604-, dated January 4, 1887.

Application filed January 11, 1886.

T aZZ whom it 71mg concern:

Be it known that I, FRANK E. FISHER, of

Detroit, in the county of Wayne and State of Michigan, have invented anew and useful Improvement in StoreService Railway-Tracks,

of which the following is a specification.

My invention consists in an improvement in tracks for store-service railways, hereinafter fully pointed out and claimed.

Figures 1 and 3 are side elevations, and Fig. 2 a plan View, ofa portion of my improved track. I v I In operating store-service railways of the class in which acar is propelled over a track either of stretched wire or metal strip, it is often desirable to 'putacurve in thetrack. To

. give a car sufficient initial velocity to round a curve at a distance from the starting-point and then travel beyond the curve necessitates too high momentum at the start, although it can readily be done with the mechanism shown in my application for a patent filed October 12, 1885, Serial No. 179,707; but in so doing there is always danger of displacingthe 2 car from the violent impetus necessary. To obviate this difficulty 1 place at any desired pointin the track a laterally-extending curve, 9, properly braced, and make said curved port-ion the highest point in the track, inclin- 0 ing the track both ways from said curve, un-

less said curve should be at one end of the track.

1 and 2 represent two portions of a storeservice railway-track, which may be made of a stretched wire or-of a metal strip.

9 represents a laterally-extending curve in the track, its ends being connected with the track 1 2, and this curve is stayedin any suitable manner, the mode shown in the drawings 0 bein b two 11 -wires 7 and 8 runnin to 4 a: a 7 a a any convenient support, to counteract the strain of the wire track 1 and 2, and a suspending-wire, 3. In somecases it is also de- Serial No.188,2l0. (No model.)

sirable to fasten the angle-piece 4 5 t0 the ends of the curve 9, and to run a stay-bolt, 6, from the angle to the curve. 7

The curve 9 is the highest point in the track, the wires 12 descending from the curve to the terminal stations. In the arrangement shown in Fig. 1 the sides of the curve are inelined at the same angle as the wires 1 and 2, the apex of the track being at the center of the curve, as shown by the dottedline 10. In the arrangement shown in Fig. 3 the curve is level, or substantially so, and only the wires 1 5 5 and 2 are inclined. By this arrangement the car starting from the terminal station of wire 1 need only be given sufficient momentum to carry it around the curve 9, when it will descend wire 2 by gravity, and vice versa.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a store-service vrailway-track of the class in which a car is propelled over the track, a laterally-extending curve located at the highest point of said track, substantially as shown and described.

2. In a store-service railway-track of the class in which a car is propelled over thetrack,

a lateral curved portion, suitably stayed, and g a straight portion inclining downward from said curved portion, substantially as shown and described.

3.1m a storeservice railway-track of the class in which a car is propelled over the track, a track consisting of two stretched wires at an angle with each other, each inclined upwardly from their terminal stations, and a lateral curved track connecting said stretched wires at their highest points, substantially as shown and described.
