DRAW-BAR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 458,802, dated June 9, 1891.

Application filed March 23, 1891.

To all whom it may concern.-

Be it known that we, LUCIE BARNES, Sr., and CHARLES O. BARNES, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Draw-Bars of Railroad-Cars, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

Experience in the running of railroadtra'ins has proven the fact that some of the most serious accidents to trains have resulted from the breaking of the draw-head from the draw-bar and the falling of the disrupted draw-head upon the track while the train was in motion, thereby throwing the train from the track.

The object of this invention is to guard against such accidents; and to that end the invention. consists, essentially, of a drawhar provided with a supplemental safety-tie connected atopposite ends, respectively, to the draw-head and to the rear portion of the drawbar, as hereinafter more fully described, and set forth in the claims.

In the annexed. drawings, Figure 1 is a top plan view of a draw-bar provided with a draw-head of the twingiaw or Janney type, provided with our improved satety-tie. Fig. 2 is a side view of the same, and Fig. 3 is a side view of our invention applied to the old style of draw-bar formed with the usual bell-mouthed draw-head for the reception of the coupling-link Z and coupling-pin p.

A represents the draw-bar formed in one piece with. the drawhead A in. the usual manner, said draw-bar being usually located beneath the cross-beam C, on the under side of the car-body, and constituting a part of the frame of said body. A stout iron or steel strap or cross-plate D, extending across the under side of the draw-bar and rigidly secured to the frame of the car-body, serves to support the draw -bar. The draw-bar is formed with an upward-projecting abutment c on its top, and a proper distance from the outer side of the cross-beam G to come in. con- To provide the draw-bar with a safety attachnient, which shall connect it to the car independent of the usual tail-bolt attachment, we provide the draw-bar with a second abutment c at the rear of the cross-beam O,

as shown and described in another application for patent, Serial No. 381,126, filed February 12, 1891. It is at or near the junction of the draw-head A with the draw-bar, where the most severe torsional strain is exerted when the car is coupled to a train and in motion, and therefore when a disruption of the draw-head occurs it usually is at a point between the two shoulders c c.

To prevent the disrupted draw-head from falling upon the track, we connect the two shoulders c 0 together by means of a suitable tie b, which may consist of a stout bolt passing through the said shoulders and provided with a head and nut, respectively, at opposite ends,

as shown; or a chain may be used between shoulders. If desired, two or more such ties may be connected to said shoulders; or a chain or chains used. In order to render the connection of the draw-head to the draw-bar still more secure, we form the under side of the draw-bar with another similar set of shoulders c c, in frontand rear of the crossplat-e D, and connect said shoulders by a tie or ties I). By employing both the top and bottom sets of shoulders and ties c e Z) and c e Z), the disrupted draw-head is retained in position to enable it to draw the car by means of the ties b 12'.

Having described our invention, what we claim as new, and desire to secure by Letters 8 5 Patent, is

1. A draw-bar provided with a supplemental safety-tie connected at opposite ends, respectively, to the draw-head and to the rear portion of the drawbar, substantially as and for the purpose set forth.

2. The combination, with the car-body, of an abutment on said body, the drawbar provided with shoulders in front and rear of said abutment, and asupplemental safety-tie 0011- In testimony whereof we have hereunto 10 meeting the two sheulders to each other, as signed our names this 17th day of March, set forth. 1891.

3. In combination with the car-body pro- 5 vided with the cross-beam O and cross-plate D, the draw-bar formed with the shoulders 0 l c and c e, and the bolts 1) 1), connecting each \Vitnesses: set of shoulders together, substantially as O. L. BENDIXON,

described and shown.
