view.v Fig. 3 an enlarged detail view of To all whom it may cocccermi:

Be it known that I, Smears ll BELL, a citizen of the United ice, residing at the city Louis, State of Missouri, United States of iiiiiericc, have invented a certain new Eul. llncoupling Device for Railway-Cars. of which he following is such a full, cl ar, and exact scription as will enable 1 y one Slill the art to Which. it eppertcins to make some, reference being had ing drawings torrning perto3; cation.

My invention relates to :1 i. LillCO vice for reilwey cars, and

theprocluction of :1 device in which o si" link 18 used to connect the uuceuphi r lever and the locking pin of the coupler heat in Which the link is prov end with a head prcven its passage l, and

through the eye oi the coupler lock. 42. other object of my ii'weiit an is to prm forms of brackets for carrying the UPFLt1i1'- rod.

In previous forms of uncoupling devices, a. for instance that shown. in my prior listen No. 1,159,470, granted Nmeinbcr 9 1915, the lower end of the link connecting the coupling rod to the locking pin has been pro videcl with an open loop adapted to pass through the eye of the locking pin. ln. such devices, While the open loop cannot he disengaged from the coupler pin while the parts are in lion 1 p0 upon the this is not apparent to it e ordii' i;y rziilw 3; employees, and I have found in practice that they bend these loops into closed position, thus preventing the removal of the parts in the manner intends ll. this of the objects of my invention, therefore, to pro vicle a link in such form that this will not occur.

In the accompanying drawings, which illustrate some forms of uncoupling device made in accordance with my invention, Figure 1 is a front elevation; Fig. 2 it top plan preferred. form of link; Fig lsometrlc pro]ection ol' the inn carrying the coupling .i'od; l to. 5 culerged detail View of the outer hracl'et :t'or

' uproot provided 3 :it one end '1 lie 16 and at the other e tor l i which will he described in ditziil hereinafter. Formed on the forward on is an eye 20 adopted to eugege -with the upper cud oi": e liulc Ql. 'lhis link 21 is provided at its upper end with an over-turned portion 252, and at its lower end with a bend or loop terminating in e heed Q-l, which is ll'littlfi of such size that it cannot pass through the eye ll of the locking pin 13. Consequently in placing the parts in position the end oi. the linlc 2]. must he first threaded through. the eye 14:, and afterward 1 20 While the rod is out of normal positioiu :1 mil when the rod is in normal position in the brackets l8, 19, the link cannot become detached. ltis evident that the lower eutl oi? the link cannot become (lisciigzigeil from the eye Li, and consequently there will be no cpg mrentreason for closing; the loop it will also be evident that the device will not operate it the upper loop is closed, and therefore there will be no inclinutioii on the part cl? a railway employee mutilate the device by bending); it.

in 9 l have shmvn inofified form of linli: i i which the lower loop so is made in it dill it form. from that shown in Fig. 3, and the head it is replaced lvy a, head 25 formed by bending; the metal oi? the link into it l circle. ln strengthen the loop c;

form prefer to pset'ting; a, portion of n in which the lower loop 23 is similar in form to that shown in Fig. 9, but the head 24 is of the same form as shown in Fig.3. 'Hi Figs. 12 and 13 I have shown a still further modification of the link, in which the upper end of the link in place of being formed by a turned over portion, as in Fig. 3, is provided with a spiral loop 27.

The bracket 18 which supports the inner end of the rod 15, is shown in detail in Fig. 4. This bracket consists of a plate 30 adapted to be secured against the front end of the car. Projecting forwardly from this plate 30 is a plate 31. The plate 31 has a portion 32 cut around three sides and bent down so as to form a bearing for the rod 15.

The plate 31 is also bent, as shown in Figs.

2 and 4:, so that two short arms 33 are formed, which project over the rod 15 and are spaced so far apart laterally that when the rod is turned into a position substantially at right angles to its normal position, the rod may be lifted out of the bracket. The bracket 19 which supports the outer end of the rod 15 is provided with removable means for securing the rod in position. In the forms shown in Figs. 2 and 5 a plate 35 is secured against the end of the car, which plate has forwardly projecting sides 36 forming a bearing for the rod, and a plate 37 passing over the top of the rod.

Plates

36 and 37 are both provided with openings 38 through which passes a cotter-pin. 39,

thus removably securing the rod in position.

It will be evident that by removing the cotter-pin 39 and swinging the top of-the rod through at an angle of substantially 90 it can be lifted from the bracket 19, hereinbefore described. In Figs. 6, 7, 8 14, 15 and 16 are shown various modifications of the outer bracket. In each of these the plate. 35 is adapted to be secured to the end or some other part of the\car, while'the plate 36 forms a bearing for the rod. In the forms shown in Figs. 7, 8, 141, 15 and 16 the holes 38 and. cotter-pin are arranged so that the cotter pin passes over the rod 15 in place of at one side of it, as in forms shown in Figs. 2, 5 and 6. The action of all, however, is substantially the same. Each provides an elongated bearing for the rod, and has removable means for holding the rod in position. The forms shown in Figs. 14 and 15 are especially adapted to be secured to the end sill of the car. The form shown in Fig. 16 provides a double bearing which may be reversed.

The operation of my device will be clear from the foregoing description. In securing the parts in position, the end 22 of the link is threaded first through the eye 14 of the locking-pin and then through the eye 20 of the rod 15 while the rod is out-of position with respect to the brackets. The rod is then swung around into a position to pass between the two arms 33 of the bracket 18,
