IMPROVEMENT IN MACHINERY FOR PROPELLING CARS.

Specification forming part of Letters Patent No. 97,343, dated November 30, 1969; reissue No. 7,669, dated May 9, 1877; application filed April 12, 1877.

To all 1071/0110 it 7211/;1 007100/ /1:

Be it known that I, G. T. BEAUR'EGARD, of New Orleans, in the parish of Orleans and State of Louisiana, have invented. new and Improved M aohinery for Propelling Cars and Boats; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

This invention relates to new and useful t improvements in machinery or apparatus for propelling ears and other vehicles on land, and boats 011 canals or rivers, by means of overhead wire or other rope, chain, or band, deriving motion from stationaryengines or other power at intervals along the route.

The invention comprises an arrangement of clamping devices, for engaging and disengaging the rope, having a constant movement above roller or pulley supports for it, suspended upon framing along the road, the clamp being connected t brackets, upon the top of the car, by a spring or yielding connection, to relieve the car or boat from injurious shocks at starting, and arranged to be operated by the conductor on the car, vehicle, or boat.

The invention also comprises an arrangement of means for raising the rope, when it is to be clamped for setting the car in motion, the pendent supports of which are necessarily lower than the clutch, to permit it to pass over them, also arranged for operation by the person standing on the car.

Figure 1 represents a side elevation of a car provided with my improvement, also showing the cord or rope and a section of the sus- I pending-framing. Fig. 2 represents an end elevation of the same. Fig; 3 represents a sectional elevation of the clamp.

The rope, chain, or band A made in long sections, and caused, by any suitable driving mechanism, to run over pulleys or guide-rollers B, suspended on curved brackets C from any suitable framing arranged along the route at suitable intervals. The said rope, &c., is

kept in constant motion and may be arranged I V to run up one track and down the other when double tracks are used.

The cars l) are provided with clam pingjaws E, suspended from a block, E, on a rod, F, supported by curved brackets G G, rising from the top of the car, above the rollers B,

the suspending-brackets of which are also curved, the curvature being in the directioi'i opposite to that of the bracket (i, permitting the block E and clamp to be carriedabovc the said roller B, and without any interference of either set of brackets.

The block E is capable of rod F, working ll] a tube supported between the central bracket G, and anotherbehind it. This tube carries a spiral spring, K, wound upon the rod, and bearing againstihe piston at one end and the end of the tube at the other, and has a tendency to keep the block E drawn back against or near to the central bracket G. The rear end of the tube is provided with an air-passage and valve, opening inward,,to admit air behind the piston when forward, to prevent the too sudden return of the block when the rope is let go.

The clamp consists of a pair of movable jaws or slides, E E, which move laterally in opposite directions in dovetailed grooves of the block E, and a clamping-screw, L, is provided with an operating-pulley, M, over which a cord or belt, N, works, the same being arranged for the attendant to operate when standing on the platform of the car; or it may be at any other convenient place. By turning this wheel M, the screw L, which is right and left threaded, will move the slides E E to and from each other, and clamp by the jaws the rope, or let it go. Then the jaws are worn out, they can easily be replaced.

0 represents an elevating-roller, mounted on a wrist-pin of a crank-shaft, P, supported on the bracket just behind the clutch, and arranged to be turned by a cord, R, working over a pulley, Q. This cordR is also arranged to be reached by the conductor on the platform or other part of the car or boat.

This roller 0 may be kept in an elevated position during the trip, so that the attendant will only have to operate the clamping device for stopping and starting the car.

The operation of the griping apparatus is as follows: By means of the cord R the pulw sliding on the and is provided. with a piston-rod, H,

ley Q is turned,- which raises, by the crank. clamping-jaws,of the elevating-roller (),crankshaft P, the roller 0. The latter,'by its shape, shaft P, and operating-cord R, substantially will receive the moving rope, guide it, and as specified. bring it between the jaws; then, by turning 3.
