SPECIFICATION forming part of Beissued Letters Patent No. 11,936, dated October 15, 1901. Original No. 621,224, dated March 14, 1899. Application for reissue illerl December 3, 1900. Serial No. 383600.

have invented certain new and useful Improvements in Automatic Oar-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in car-couplers of the type known as the J anney for use by itself or in connection with any form of the Janney coupler.

An object of the invention is to provide a car-coupler of this type which may with little expense and change be inserted in the head of any common form of link-and-pin coupler at a nominal cost and which may be removed at any time to permit a link and pin to be used. V

A further object is to improve upon the op-? eration of the coupler, so that there will be less danger to the brakeman in providing means for opening the coupler in case it becomes accidentally closed when the cars standuncoupled, an objection nowencountered in the J annoy type, and also to do away with rods extending" on the side or ends of the car, which are apt to cause accidents to brakemen in jumping from between the cars after coupling the same; and the invention consists in other minor improvements, which will be more fully pointed out in the specification and claims.

For afull and complete understanding of the invention referenceis to be had to the K views, and in which-- v 'closedpositiongj Fig. L is a, view offa spring device which may be used in connection withthe coupler when desired. Fig. 5 is a view in side elevation of a common form of linkand-pin draw-head and my coupler ready for insertion into the head of the same. is a. sectional view of the head of the improved coupler, taken on line mg of Fig. 2.

In the drawings, A refers to the head of the improved coupler of the for rn'lof'a Janney coupler having two jaws a, aiin the forward extremityof the former, being pivoted to the hinged lock portion a, which is opened and shut by means of a link D, pivoted at its forward end to the middle portion of a, as shown, and extending diagonally rearward through an opening a formed in the jaw a and being connected at its rearend to the front end of a sliding rod E, mounted in suitable brackets The jaw a has a' Fig. 6

2,) and this link is capable of a partial revolution by means of raising a lever d, rigidly attached to the link, so as to raise the projection (1 from a horizontal position to a vertical position with respect to said link, which permits the projection to escape or be forced by said lever through the opening a, and thus unlock thehinged portion a, (see Fig. 1,) and when in this locked position if the coupler comes in contact with a Janney coupler or a similar coupler in a locked or unlocked position the impact will force the hinged portion shut, and handle d will dropinto a depressed or vertical position, thereby throwing the proj ction d behind the ofiset a; thereby securely locking the hinged portion a. I

The head of the coupler A is provided with a rearwardly extending extremity A, and both the head and this portion are of suitable size'to be readily "inserted in the head 0 and draw-bar G of atype similar to a common form of link-andepin coupler, or they may be I draw-barof the former being apertured to permit the coupling-pin to be inserted in it.

Sliding rod E may have one end of a spiral or coil spring secured to it between the brackets e to assist in the forward thrust of the link D to open the hinged portion a when the lever d'is raised; but this spring is not an essential part of the device, as the coupler can be operated readily by the lever itself.

F is a reinforcement or block to strengthen the head A and may be used or not. NVhen it is used, it is held in place by means of a coupling-pin f, passing through the head A and into a corresponding or registering apere ture in the block, and a corner of said block may be cut away adjacent towecess a so as not to interfere with the operation of link D.

By this arrangement it will be readily seen that a brakeman by using lever d is not compelled to go between the cars, as he would have to do in case he had to unlock the J an.- ney coupler when the hinged portion thereof or door became closed and he would not be in danger of being caught by the handle-bar, such as are used tooperate J anney couplers to unlock or uncouple-cars, when he had coupled the cars and jumped back to get out of the way, which often happens where such bars are used. The link D is so arranged that the hinged portion or door a is capable of opening only a suflicient distance to permit an easy coupling of the cars, and this link is especially constructed of steel or suitable material to insure great strength and certainty of action; V

Having thus described my invention,.what I claim, and desireto secure by Letters Patout, is i 1. The combination in a car-coupler, of a head and draw-bar capable of use with or independently of a link-and-pin coupler, a

hinged portion on one of the jaws of ,the

coupler, one of said jaws having a recess formed therein and an o'fiset adjacent to said recess, a link having its front end pivotally connected to the said hinged portion and pro- .jectin'g through said recess, aslidiug rod conv upsa nected to the rear end of said link, a projection on said link adapted to contact at certain times with said offset to lock the coupler,

a handle on the said link for operating the same, and means to automatically close and lock said hinged portion of the coupler when 6o two cars com o together, substantially as specified.

2. A car-coupler comprising a head and draw-bar capable of attachment in a link-andpin coupler, a knuckle-joint or hinged portion pivoted to one of the jaws of the coupler, one of said jaws having a rear cut-away re-- cess therein and an offset at the rear end of said recess, a link pivot-ally secured at its front end to the middle part of the hinged 7o portion, and passing through said recess, its rear end being pivotally secured to a sliding rod, said rod being mounted in suitable brackets on the bottom of a car, a projection on said link capable, when in a horizontal plane 75, I with said link, of contacting with said offset, when the hinged portion is closed, to lockthe coupler, and a handle on said link for revolving the link and to operate the same, substantially as specified.

3. The combination in a car-coupler, of a head and draw-bar capable of use with or independently of a link-and-pin, coupler, a knuckle-joint or hinged portion on one of the jaws of the coupler, a link pivotally secured at its forward end to said hinged portion, passing rearwardly through a cut-away portion in one of said'jaws and being secured at its rear end to a sliding bar, said bar being mounted in suitable brackets on the car-bottom, an oifset on one of the jaws at the rear end of said cut-away recess, a projection on said link capable of securely contacting with said oifset, when said projection is in a horizontal plane with respect to the link and said hinged por- 5 tion is closed, a handle on said link for re- -volving the same, and meansto open said hinged portion when it is closed and means to automatically close and to lock said hinged portion of the coupler when two cars come [03, itogelther, substantially as described and set In testimony whereof in presence of twofwitnesses.
