CAR-COUPLING.

SPECIFICATION forming part of LettersA Patent No. 551,091, dated December 10, 1895. Application iletl October 5,1895. Serial No. 564,792. (Nolnodel.)

To @ZZ whom t may concern:

Be it known that I, VILLIAM P. NYE', a citizen of the United States, residing at Tazewell, in the county of Tazewell and State of Virginia, have invented a new and useful Car-Couplin g, of which the following is a speciiication,

The invention relates to improvements in car-couplings.

The object of the present invention is to improve the construction of car-couplings of the Janney type and to provide simple and efficient means for limiting` the vertical movement of the draw-heads on each other when coupled to prevent them from becoming accidentally uncoupled, and also to prevent one of them from dropping to the track in event of its being pulled out of its fastenings.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a car-coupling constructed in accordance with this invention. Fig. 2 is a side e'levation of two draw-heads coupled.

Like numerals of reference indicate corresponding parts in both the figures of the drawings. I

l designates a drawhead of the J anney type provided with the usual pivoted knuckle 2 and adapted to couple with a corresponding draw-head, as will readily be understood. The draw-head is provided at its knuckle side with an outwardly-projecting horizontal arm 3, located at the top of the draw-head and extending beyond the front thereof when the knuckle is closed. At the other side of the draw-head is arranged a horizontal fiange or ledge 4, located at the bottom of the drawhead and extending rearward from the front thereof. When two draw heads are coupled, as illustrated in Fig. 2 of the accompanying drawings, the arm 3 of one drawhead overlaps the other draw-head and is located above the ledge 4L thereof, whereby stops are provided to limit the vertical movement of the draw-heads on each other to Vprevent. them from being thrown out of engagement by inequalities` of the road and becoming uncoupled, and also to prevent a draw-head from dropping upon the track and wrecking the cars in rear of it should it be pulled out of its car and become detached therefrom.

It will be apparent that the arm 3 and the flange or ledge 4 permit the necessary vertical play of the draw-heads and a vertical adj ustment thereof, so that a light or empty car can couple with a heavy one without twisting or straining the couplings. The arm 3 and the flange 4 do not interfere with the automatic coupling of the draw-heads,`-and they may be constructed in any suitable manner and be formed integral with or be secured to the draw-heads.

It will be seen that the safety device for carcouplings of the .Ianney type and analogous ones is exceedingly simple and inexpensive in construction, that it is positive and relie able in operation, and that while preventing absolutely two draw-heads from becoming un coupled or disengaged through vertical moveyment on each other it permits a limited vertical movement or play to avoid straining the couplings or their connections with the cars. It will also be apparent that it does not interfere with the free use of the coupler, and the efficiency of the latter is nowise impaired, and the operations of coupling and uncoupling may be performed with as great facility and convenience as though the safety device were not applied.

Changes in the form, proportion, and minor details of construction may be lresorted to without departing from the principle or sacrificing any advantages of the invention. What I claim isl. A car coupling of the Janney type or the like provided at one side of the draw-head with a forwardly projecting arm, and having at the opposite side a ledge or flange, whereby, when two draw-heads are coupled, the iianges and the arms will lie in the same vertical plane and form stops to limit the vertical movement of the draw-heads on each other and prevent them from becoming separated, substantially as described.

2. A draw-head of the .Ianney type provided at its knuckle side at its top with an outwardly extending horizontal arm, and having at its other side at its bottom, a horizontal flange IOO or ledge extending rearward from the front my own I have hereto affixed my signature in of the draw-head, said arm being of a length the presence of two Witnesses. to project beyond the draw-head, when two draw-heads are coupled, and to lie above the VILLAM P. NYE. adjacent flange or ledge, substantially als and \Vit11esses: for the purpose described. JOHN Il. SIGGERS,

In testimony that I Claim the foregoing as HAROLD II. SIMMS.
