To all whom it may concern:

Be it known that'we, CHARLES A. CARs- CADIN and GEORGE A. WoonMAN, citizens of the United States, both residing at Chicago, inthe county of Cook and State of Illinois, have jointly invented certain new and useful Improvements in Uncoupling Devices,'-of

which thefollowing is a specification.

' Our invention relates in general to uncoupling devices such as are in use upon railway'cars andthe like and aims to provide a new and improved means for lifting the locking pin of a coupler of any ofthe ordinarytypes. I, a

One of the principal objects of our invention isto provide a car uncoupling device which maybe operated from the side of the car and which will be so constructed that the operating rod maybe connected directly to the locking pin oithe coupler, obviating therebythe use of chains, links and 'clevises, which are at present employed inmany forms of devices of this character to connect the operating rod'to the locking pin. The use ofuncoupling devices employing these members to connect. the operating rod to the locking pin of the coupler'hassubjected the railway companies to considerable annoyance and expense by reason-0t the 'theft of these parts, which has thereby renderedthe uncoupling device inoperative and' r'equired thebrakeman'to'enterbetween the cars to couple and uncouple "them great risk to thereof;

himself and in violation otthe regulations of the railway commission." Our invention description as it is better understood when.

taken in connection with the accompanying drawing illustrating preferred embodiments "Qnthe drawing, Figure 1 is a top plan view of a portion of a "car' and coupler pro vided' an uncoupling devlce embodying our invention; Fig. 2 is an enlarged transverse section through the inner bracket and slide provided to connect the inner end of the operating rod to the car; Fig. 3 is a horizontal section taken substantially on the line 3-'3of Fig. 2; Fig. 4: is an enlarged-side elevation of the slide; Fig. 5 is a transverse section similar to Fig; 2 of a somewhat different embodiment of our invention, and Fig. '6 is a similar view of stillanother embodiment.-

Referring to the drawing, the invention comprises an operating rod 10, an outer bracket 1l,-a'n inner braclret l2 and a slide 13 carried by the bracket 12, the rod 10 pass"- ing through the bracket 11 and slide 18 as will be later described. In the presentinstance'the operating rod is connected directly to the locking pin of the coupler by an arm 14: extending outwardly fromthe car at right angles to the body portion of the rod and inserted through the eye 15 of the locking pin 16, the endof the arm 14 being bent at 17 to prevent its disconnection from the locking pin when the parts are inoperative position upon the car; The bracket 11, which embraces the outer end of the operating rod,- is secured to'the car at 18 adjacent one side so that the operating arm 19 at the endof'the body portion of'the'rod adjacent the side of the carmay be-operated'without requiring the brakeman-to enter between the cars to couple and uncouple them. The bracket 11 is of the ordinary construction except that the aperture 21 is formed to per unit the operating rod *to' move pivotally about-the braclet l1"as acenter through a limited are as" the coupler head is pulled from'o'r pushed toward the car in service; The bracket-"12 consists in thepresent instance ofalbase-plate 220i" suitable formationto be secured to the car by'bolts'or other fastening means 23 extending through apertures2t'in the fastening plate. This fastening' plate is provided with a horizontally disposed rail or bracket arm 25. In the embodimentof the invention shown in Figs. 1 to 4 this'arm is of T-shaped form consisting are supporting web 26 carrying a flattened head 27; The head 27 extends throughout theiength of'the arm and is'embraced by the slide "13 carrying-the operating rod. 'The slide 13 is formed at its bottom with a T shaped-slot QSadapted to fit over the bracket arm 25 and permit the slide to move longitudinally of the car upon 'theb'racket arm.

The slide 13 is preferably provided with an upwardly extending web 29 having an elongated longitudinally disposed slot 30 through which theoperating rod 10 is disposed, as indicated in dotted lines in Fig. 1. Adjacent the forward end of the bracket arm are provided outwardly extending webs 31 and the width of the opening of the slot 28 is preferably just sufficient to permit the body portion of the slide to move easily past these websas it moves backward and forward when the cars are in service. At the rear end of the slide a pair of stops 32 extend inwardly of the opening of the slot 28 to adjacent the web of the bracket arm, thus disposing them in position to engage the webs 31 of the bracket arm to pre- Vent excessive outward movement of the slide with respect to the bracket 12.

In Fig. 5 a somewhat modified form of our invention is disclosed wherein the slide which embraces the operating rod consists of a hollow casting 33 provided with a pair of parallel elongated longitudinally extending slots 34, through which the operating rod 10 is disposed. The lower edges 35 of the casting are inturned to provide a slot embracing the bracket arm 36, which in this embodiment of the invention is identical in shape and construction with that described in connection with Figs. 1 to 4:. In order that the casting may be held in proper position upon the bracket arm the sides of the casting are deflected inwardly at 37 to engage the upper surface of the bracket arm.

In Fig. 6 a third embodiment is set forth wherein the bracket arm 38 is provided with a rounded bearing surface 39 and the slide 41 is provided with a slot of suitable shape to engage and slide upon the surface 39. In this embodiment the lower edges 42 of the slide engage the central supporting web 43 of the bracket arm and the webs 44 on this arm are provided to act as stops and terminate a substantial distance beneath the portion of the bracket arm embraced by the slide and suitable downwardly extending stops 45 are provided to engage the upper ends of these webs to prevent excessive outward movement of the slide with respect to the bracket arm. I

An uncoupling device made in pursuance of our invention may be positioned upon the car by inserting the end of the operating rod through the slot in the slide and through the aperture in the bracket 11. The bracket 12, is then connected with the slide by moving the front of the slide over the rear of the bracket arm into normal position when, after engaging the lifting arm 14; in the eye of the locking pin of the coupler, the two brackets 11 and 12 may be secured in place. The bracket 12 is preferably mounted close to the car body so that the slide can not be moved rearwardly to disengage it from the bracket arm of this bracket. The preferable normal relative relation between the operating rod and the slide 13 and bracket 12 is that shown in Figs. 1 and 4. When the slide is in its rearmost position, the operating rod is preferably disposed adjacent the front end of the slot of the slide. This permits the operating rod to move inwardly to substantially against the car body and to move outwardly throughout the full length of the sliding movement between the slide and bracket member. It will be apparent that the proper dimensions of the parts may be readily determined to give the operating rod the freedom of movement necessary to move with the coupler as the coupler head is pulled away from or pushed toward the car.

The parts are few in number, simple and may be cheaply constructed, and when connected as described, can none of them be re moved without detaching one of the brackets fastened to the car.

It will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit or scope of the invention or sacrificing any of its material advantages, the forms hereinbefore disclosed being merely preferred embodiments thereof.
