CAR ATTACHMENT FOR ELEVATED RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 233,016, dated October 5, 1880. Application filed August 29, 1879.

T 0 all whom it may concern:

Be it known that I, CHARLES E. POWERS, of Boston, in the county of Snftblk and State of Massachusetts, have invented anew and useful Improvement in Car Attachments for Elevated Railways, of which the following is a specification.

Myinvention consists in a downwardlypro- Jccting bracket which is suspended from the car and acts both as a side brace to prevent ecarfrom tipping and also as a hook to clasp e stringer beneath the rail, and thus give additional security.

My invention also consists in a device by which the bracket may be turned up so as to allow the car to be switched or to cross an intersectin g track.

In the drawings, Arepresents the main girder of an elevated railway, and L the car. The upper angles of the girder A are formed by T-pieces B, one flange of each extending be yond the side of the girder, as shown in Figure 3, to afford a strongprojection, under which the hohjling-hook E runs, and with which the hook in case of accident engages and thus prevents the car from leaving the track.

To the T-iron B are firmly attached the crossties and the string-pieces O, which forms a bed for the rail D. This part of the structureviz., the T-iron, the cross-ties, the stringer O, and the rail D-forms a firm resistin g stringer to take the strain of the hook K K K in case of accident.

The holding-bracket K K K is firmly attached to the under side of the ear, and is braced and bolted, as shown in Fig. 3. This form is to be used on tracks that have turn- E or the bracket tables or sliding switches. The hook E E is to be' used on tracks that have the ordinary system of switches.

The holding-hook E E is pivoted at E Fig. 3, in a strong housing, and is thrown in and out by a crank-shaft, D Figs. 1 andl 3. The Crank 1) passes through a slot, H, in the hook, so that when the shaft is turned, as it may be by the lever D, Figs. 1 and 3, it will operate through the crank D to swing the hook E E in or out. This crank-shaft is also mounted in a strong housing firmly attached to the car, and the angle of the crank is so adjusted to the hook E E that the crank will stand at right angles to the book when the hook is in place, and as both the hook and crank are mounted in a strong housing or housings the whole becomes a very firm device for holding the car to the track.

Having thus described my invention, what I desire to secure by Letters Patent is I. On an elevated railway, the car L and the side bracing-hook bracket K K K in combination with the girderA, the said bracket descending below the upper part of the main girder, whereby it may serve as a wind-brace and a hook, all substantially as described, and for the purpose set forth.

2. The combination of the swinging hookE E, the crank-shaft D crank D, and ear L with the stringer B of the beam-girder A, substantially as described, and for the purpose set forth.

CHARLES E. POWERS.
