DRAW-BAR FOR RAI LWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 398,716, dated February 26, 1889.

Application filed September 22, 1888. Serial No. 286,058. (No model.)

To all whom it may concern:

Be it known that we, SAMUEL trsunn and CHARLES C. FISHER, both residents of Steubenville, in the county of Jefferson and State of Ohio, have invented a certain new and useful Improvement in Draw-Bars; and we do hereby declare that the following is a full, clear, and exact description of the invent-ion, wliich. will enable others skilled in the 1 art to which it appertains to make and use the same.

This invention relates to an ini )m\'ement in draw-bars.

The object is to produce a draw-bar which shall be of such construction that should any of the parts become broken or injured from any cause they may be removed readily for the purpose of repair and without the necessity of entering the car. FLll1l1l1llOl'G,l;l1O object to produce a draw-bar which shall be simple of construction, eliieient and durable in use, and com mratively inexpensive of production.

Heretoforc it has been customary to secure the draw-bar to the bottom of the car by means of bolts, which extend through the car-floor and into the interior of the car. Now, should any accident happen to the draw-bar, and should the car be loaded with any substancesuch, for instance, as grain-it will be necessary to unload the ear in order to get at the bolts hohiling the draw-bar in place. It is the object to overcome these obstacles in a simple and effective manner; and to these ends the invention consists in the improved construction and combination ofthe draw-bar, whereby the obstacles above mentioned willv be overcome in a simple and effective manner.

In the accompanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, we have illustrated one form of device embodying the essential features of our in vention, although the same maybe carried into effect in other ways without in the least departing from the spirit thereof, and in these d rawin Figure l is a bottom plan view showing the device secured to the frame of the car. Fig.

2 is a longitudinal vertical sectional view showing the manner in which the device is secured to the car. Fig. is a perspective view of the device, part of the frame-work of the car being cut away; and Fig. 4- is a detail view of one of the folloner-plates.

Referring to the drawings, A designates the lower front portion of the bottom of a car, to which is secured the body-bolster 1 and the end sill, 2, having bumpers 3 mounted thereon. To the rear portion of the coupler-head 1 is loosely secured a coupler-lmr, 5, on which is mounted a washer, U, the said coupler-bar extending back nearly to the body-bolster 11. Upon this coupler-bar are mounted two follower-plates, 7 and 8, provided at each end with openings 9 and 1t), and in these openings are placed two rods, 11 and 12, which pass back and through the body bolster and through a plate, 13, on the opposite side, and are held in place thereon by means of pins 14. Upon the rods 11 and 12 are secured two butfers, 15, which are held together by means of bolts 16. In order to cause these butters to be held at a certain distance apart, collars 17 are placed on the bolts, so that when the nuts are tightened the collars will prevent the butfers from being drawn too close together.

Ypon the rods 11 and 12 and between the follower-plates T and S are mounted two springs, 18, the ends of the rods extending through the follower-plate T, and are secured on their outer side by means of a pin, 19, which passes through an opening in the said rods. The coupler-bar 5 has also mounted upon it a spring, which bears at each end against the follower-plates, the outer end of the said cou 'ner-bar being provided with a collar, 90, held in place thereon by means of a pin, 21, which engages an opening, .22, in the said bar. The object of this spring on the coupler-bar is to remove all strain'from the same when the cars are being coupled or when being drawn over the track.

In order to strengthen the device additionall y and to prevent the springs from bulging up, and thus bearing against the rods upon which they are mounted, two L- shaped iron braces are placed on the bolt 11; between the edge of the collar and the side of the butter and extend down and are secured by means of bolts 23 to the beams 2i of the car.

Having now described the different parts of our device, we will proceed to show its operation:' Should the draw-bar become injured from any cause and it is desired to remove it, it will only be necessary to remove the pins in the ends of the rods 11 and 12 and unscrew the bolts 25L, holding the L-shaped iron braces in place, when the entire dran head and coupler-bar may be removed.

It will thus be seen that, although this device is exceedingly simple of construction, it will be found highly eflicient and durable in use, and will save a considerable loss of time as and for the purpose specified.

and labor to railroad-men when it is necessary to remove the draw-bar.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is- I 1. In a draw-bar, the combination of the coupl'er-head, a coupler-bar loosely secured thereto, apertured followereplates on the coupler-bar, rods e-Xtendin g through thesaid plates, springs on the rods between the plates, buffers behind the plates, and bolts for holding the buffers in position, substantially as described.

2. In a draw-bar, the combination of the coupler-head, a coupler-bar loosely secured thereto, apertured follower-plates on the coupler-bar, rods extending through the said plates, springs on the rods between the plates, butfers behind the plates, bolts for holding the buffers in position, and L-shaped braces beneath the rods, substantially as and for the purpose specified.

3. The combination of the butters, bolts for holding the same in place, and L- shaped braces secured to the said bolts, substantially 4. The combination, with a coupler-head, of a movable bar carrying a spring, substan tially as described.

In testimony that we claim the foregoing as our own we have hereunto affixed our signatures in presence of two witnesses.
