SPECIFICATION forming part of Letters Patent No. 449,646, dated March 31, 1891.

Application filed August 7, 1890. serial No. 361,380. (No model.)

To all whom it may concern/.-

Be it known that 1, JOHN M. BLONDELL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Draft-Poles for Horse-Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable other skilled in the art to which it appertains to make and use the same.

My invention relates to draft-poles for railway horse-cars; and it consists in certain novel parts and combinations of parts, the separate features of which will be separately and specifically pointed out in the claims concluding this specification.

Referring to the accompanying drawings, Figure 1 represents in vertical section a draftpole embracing my invention as coupled with the draw-iron and pole-support of a streetcar. Fig. 2 is a top View of the draft-pole. Fig. 3 shows in separated relation the polesocket iron and its separate coupling-eyed iron, and Fig. 4 shows the pole-socket iron.

In street-car poles the coupling-irons are subject to destructive wear and breakage, and when so rendered useless must be renewed by removing the pole-iron and rewelding thereto a new coupling-eye, and this requires the stripping of the coupling-irons from the pole to be renewed at the forge.

I make the coupling-pole iron of two parts, a bifurcated strap-iron part a, bolted to the pole in the usual way and terminating in a socket end I), and a coupling part 0, having the eye 0 for the coupling-pin adapted to be fitted and secured within said socket, so that coupling-eyed part can be easily removed and replaced when worn out without removing the pole-iron.

d is the pole, and e is a stay-brace to support the pole and hold it at a proper elevation, and f g the bolt and its guard for securing the whifiletree to the pole. I make this stay-brace with a vertical arm e,having a screw-thread at its upper end, which passes through coincident openings in the pole-iron socket and in the coupling-eyed iron, and to which it is secured by nuts h above and below the pole-coupling iron, way of securing the coupling-eyed iron to the pole because it is convenient when a stay is used; but it is obvious that the coupling-eyed iron may be secured to the pole-iron by separate bolts '2; when a stay-brace is not used to the pole.

The coupling-eyed iron is adapted to be coupled by the coupling-pin j with the car draw iron is, and in connection with this coupling-pin and draw-iron Iemploy an adjustable stay-iron coupling Z for coupling the stay-brace to the draw-iron by the couplingpin for supporting the pole-iron upon the draw-iron coupling-pin. For this purpose I secure the stay-coupling iron Z near the lower end of the stay-brace arm, and I provide the draw-iron with a lower projecting arm or bracket m, having an eye to receive the coupling-pin, whereby the pole is supported and held in a horizontal position to the draft and the front end of the pole prevented from flying pup or down by the movements of the horses. This lower supporting-oouplin g stayiron, in connection with a couplingpin, passes through the upper and lower arms or jaws of the draw-iron, serves to prevent the snapping off of the upper arms or jaws of said drawiron, which otherwise would be liable by the flying up or down of the pole, and make this lower stay-coupling iron adjustable by its screw-threaded end and the -double nuts n on each side of the brace-stay arm, so that the stay-coupling can be lengthened and shortened and to adapt it for other coupling-irons in use. I also provide for adjusting the lower 8 5 or stay-coupling iron vertically by means of its threaded arms and nuts for the purpose of adapting said stay-coupling iron to cars having various-sized coupling-irons.

A stay-brace for the draft-pole of a horsecar is very old as a separate braced attachment to the pole and coupled to the car by a coupling-pin distinct and independent from the pole-coupling pin, and a coupling-iron for a doubletree has been formed with an eye at 91' one end to receive the coupling-pin of the draw-iron and at its other end with eyed jaws by which it receives the doubletree and its and I prefer this 50 pivot-pin, and such doublet-ree-coupling iron has been formed with a brace separately pivoted to the draw-iron.

I claim as my improvement 1. The combination, with a draft-pole, of a coupling-iron therefor composed of a strapped,

part terminating in a socket end, an eyed part fitting said socket, and a stay-brace having a vertical arm passing through and bolted to the socket-connected parts.

2. The combination, with a draft-pole, of a stay-brace having a coupling-iron, means for vertically adjusting said staybrace, and means for horizontally adjusting said coupling-iron.

3. The combination, with a draft-pole, of a stay-brace having a vertical screw-threaded arm, the nuts for securing it to said pole, and a screw-threaded eoupling-iron on said staybrace having and horizontal adjustment may be made of the supplemental coupling parts.

In testimony whereof I afiix my signature in presence of two witnesses.
