PUSH-BAR FoR LOCOMOTIVES.

SPECIFICATION forming part of Letters Patent No. 400,518, dated April 2, 1889.

Application filed December 21, 1888'. Serial No. 294,321. (No model.)

certain novel features hereinafter described and claimed.

In the accompanying drawings, Figure .l is a perspective view showing the cow-catcher and my push-bar in position for coupling to a car. Fig. 2 is a front elevation 'showin g the push-bar swungaround to the side, as it appears when not in use. Fig. 3is a horizontal section of the push-bar.

Referring to the drawings by letter, A designates the cow-catcher, of the usual orany preferred construction, and provided with the cross bar or sill B at its upper rear edge, as shown. To the cross bar or sill B, at the ends of the same, I secure the castings O, which are provided with the forwardly-projecting perforated lugs D, between which the end of the push-bar is adapted to fit when not in use, as will be presently more fully described.

At the center of the cross bar or sill B, I secure the support E, having the forwardlyprojecting perforated lugs or ears F, as shown.

The push-bar comprises the draw-head G and the coupling-bar H. The rear end of the draw-head is inserted between the ears F and pivoted between the same by a pin, I, inserted vertically downward therethrough, and having a spring, J, formed integrally with its upper end and projecting forward therefrom. A supporting-pin, K, is secured to the free end of this spring and projects downward through the draw-head, and is provided at its lower end with an annular shoulder or head, L, which bears against the under side of the draw-head, and thereby supports the pushbar in proper position for coupling. By providing this spring and supporting-pin I am enabled to make the joint between the drawhead and the support E sufficiently loose to allow the proper play of the draw-head and yet prevent the draw-head having such vertical movement as will prevent the proper rest against the outer sides of the draw-head,

and have their front edges adapted to contact with the vertical shoulders N of the drawhead and thereby limit the forward motion of the coupling-bar. The said wings are connected to the coupling-bar by means of the lateral extensions P, which slide in the slots M in the sides of the draw-head, as shown. The coupling-bar is further provided at its opposite ends with the openings Q R, the opening Q being adapted to receive the couplingpin carried by the draw-head of the coupling on the car, while the opening R is adapted to receive a locking-pin to lock the coupling-bar in its extended position. The said lockingpin is mounted in a cylinder or sleeve, 8, erected on the upper side of the draw-head at the front end of the same, and has its lower end normally resting on the coupling-bar and supported thereby, so that when the coupling bar is drawn forward and the opening R is brought under the said pin the pin will automatically fall into engagement with the said opening andlock the coupling-bar in its extended position.

In practice, when it is desired to couple the locomotive to a car, the coupling-bar is drawn forward to the front end of the draw-head, as shown in Fig. 1, and the front end of the coupling-bar is then coupled to the car in the usual manner, as will be readily understood. YVhen the push-bar is not inuse, the lockingpin is raised and the coupling-bar pushed backward, after which the push-bar is swung around to the side, as shown in Fig. 2, and locked in the said position by inserting a suitable pin through the perforations in the lugs D and the opening Q, in the end of the coupling-bar.

My improved device is very simple in its arrangement and is composed of few parts,

so that it can be manufactured at a small cost and is not liable to get out of order. \Vhen the device is not in use and it is moved around to the side, as shown and described, it is out of the way and occupies but very little room.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A push-bar for locomotives, comprising a horizontal]y-swinging draw-head and a coupling-bar carried by said draw-head and adapted to slide longitudinally therein, as set forth.

2. A push-bar for locomotives, comprising a draw-head having a vertical sleeve or cylinder on its upper side, a coupling-bar slid- 1 cured to said spring and extending downward through the draw-head, and provided at its lower end with an annular shoulder bearing against the under side of the draw-head, as set forth.

at. The combination of the draw-head, having slots in its sides and provided with the vertical shoulders N, and the coupling-bar sliding in the draw-head and having lateral extensions projecting through the slots in the draw-head, and provided with the wings 0, bearing against the sides of the drawhead and adapted to contact with the shoulders N, as set forth.

5. A push-bar for locomotives, comprising a horizontally-swinging draw-head pivoted to the front end of the locomotive, and carrying a coupling-bar which is adapted to slide 1ongitudinally within the draw-head.

6. The improved push-bar for locomotives herein described and shown, comprising the support E, the horizontally-swinging drawhead, the coupling-bar carried by the drawhead and adapted to slide longitudinally therein, the casting adapted to receive the end of the coupling-bar when not in use, the pin pivoting the end of the draw-head to the support E, the spring projecting from the upper end of said pivot-pin, and the supportingpin depending from said spring and supporting the draw-head, as specified.

7. A push-bar for locomotives, comprising a horizontally-swin gin g draw-head carrying a couplin g-bar, and the pin for locking the drawhead to hold it from swinging, as set forth.

8. A push-bar for locomotives, comprising a horizontally-swin gi n g draw-head carrying a coupling-bar, and the pin for locking the draw-head to hold it from swinging, and the castings C on either side to lock the drawhead when swung around, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
