To all 1072 0752? it ma camera.-

Be it known that I, Sam-mm I-I. GA B- sma, a citizen of the United States 'of Amer: ica,residingat the city or St. Louis, State of Missouri, Unit-ed States of America, have invented a certain new and useful ouple'r- Release Rigging, of which the following is such a full, clear, and exact asses tion as will enable anyone skilledth-e art to which it ap'pertains to make and use the same,- reference being had to the ccompan 111g drawings, forming part of this Speeisa tien. i

My invention relates to a coupler release rigging and particularly to that type of rig in-g in which the actuating rod rotatesto lift the pin and in which thear'mior'equi-valent operating portion of the rod moves in i'i'n'iso'n with the locking pin The object of my invention is to so con struct a release rigging of the classdescribed so that the handle, by means of which the actuating rod is controlled, may return to normal position, while the coupler pin is in raised or unlo ked position.

In the accompanying drawings which illustrate some forms of coupler release rlg'gmg made in'accordance with my invention, Fig

ure 1 is top plan view of a portion of a rail way car to which one form of device is applied. Figure 2 is an end view, Figure 3 is a front view, Figure 4 is a plan view showing a modification, Figure 5 isan enlarged section on the line 55 of Figure 4, Figure 6 is an end view of the handle, Figure 7 is a front view of the handle, Figure 8 is a plan view showing a further modification, Figure 9 is an end view of the form shown in Figure 8, Figure 10 is a plan view of a further modification, Figure 11 is a section taken on the line 1111 of Figure 10. Figure 12 is an end view of the handle shown in Figure 10. Figure 13 is a plan view showing a still further modification, Figure 14 is an end view of the parts shown in Figure 13 and Figure 15 is a front View of the connecting link shown in Figures 13 and 14.

1 indicates a railway car carrying a coupler head 2 resiliently mounted in any usual manner in the striking block 3 and provided with a lock pin 1 by means of which its knuckle is controlled. Referring first to Figures 1, 2 and 3, 6 is the actuating rod or rock shaft rotatably mounted in brackets 7 secured to the end of the car. The rod 6 is prov ded with a f rward y proj g sea 8 having a lateral extension 9', preferably provided with a turned over end'or hook 10. The eiiterfsion' 9 passes through an 'eye'12 carriedon the ldck-Ypin 4 and elongated to extend in the direction or the length of the 1 car. his construction allows the operating arm' and lock pin to have relativemovement both laterally and longiti'idin'ally in a horizontal plane, but enforces their moverrrent in unison vertically. In order that-the handle 13 may not project into the space between the cars when thel lock pin is in raised position, I provide the end of the rod 6 with a short crank arm- 14 to which the handle1 '3 is pivoted at 15* so that the'handlemay drop down into normal or verticalpo's itiorr, as best shown in Figure 2, while the pin remains raised. I I I In Figures 4 to' 7 I have shown a modified form of device in which the operating arm 8' is replaced by an arm comprising a down wardly and forwardly projecting part 16 and a part 17 extending parallel with the upper face of the coupler when the pin is in lowered or locked position. In th-is con stru'c-tiomthe hook IOis formed on th'e e n'd of the part 17 and the said part extends through an eye 18 carried on the pin 4: and elongated like the eye 12' but .exteiiding in a transverse direction instead of" longitudi many; This construction, like that above placed over the crank arm 14 and held in position by a bolt 20. I havealso shown the cast brackets 7 replaced by brackets 21 formed of sheet metal and having bearings 22 struck up from the metal.

In Figures 8 and 9 I haveshown a 1nodi-' fication in which the actuating rod 6 is carried in a singlebracket 23 provided with a tapering passage 24 to allow the outer end of the rod to move in a horizontal plane to accommodate the longitudinal movement of the coupler head. In this construction, the end'of the rod 6 passes directly through an are c his usual 9a t P The end of the rod 6, while not distinct from the body of the rod, forms in effect an operating arm functioning in a manner similar to the operating arm hereinbefore described. I have also shown the crank arm 14 flattened and provided with a turned over portion 26 forming a stop for the handle 13, thus obviating the necessity of bifurcating the end of the handle as shown in Figures 1 and 3.

In Figures 10, 11 and 12 the rod 6 is similar in form to that shown in Figure 1 but the use of the elongated eye 12 is obviated by the use of an inner bracket 27 slotted to allow the rod to move toward and away from the car. The handle 13 is provided with an aperture 28 to pass around the rod and with a stop 29 to contact with the crank arm 14. A pin 30 holds the handle in place.

In Figures 13, 14 and 15 the end of the arm 8 is connected with the lock pin by a link 31 pivoted to the said arm at 32 and provided at its lower end with an elongated loop 33 engaging with the eye of the lock pin. The elongated form of the loop 33 allows for the lateral movement of the coupler while the pivot joint 32 compensates for the longitudinal movement. As in the other forms described, however, the arm and lock pin can move only in unison in a vertical direction. The handle in this construction, as in that last described, passes around the rod 6. The crank arm 14; is, however, not used, the handle being provided with a stop 34: and the rod with a pin 35, serving both to cooperate with the stop and to hold the handle in position.

Having fully described my invention what I claim as new and desire to secure by Letters Patent of the United States is:

1. In a device of the class described, the combination, with a coupler head having a lock pin of an actuating rod rotatably mounted, an operating arm carried by said rod, said arm and lock pin operatively con nected to have relative movement both longitudinally and laterally in a horizontal plane, but to move in unison vertically and a handle for said actuating rod having movement relative thereto, whereby said handle may return to normal position when the lock pin is in raised position.

2. In a device of the class described, the combination with a coupler-head provided with a lock-pin having an elongated eye, of a rock-shaft, an operating arm carried by said shaft and extending through said eye, whereby said arm and pin move vertically in unison but are capable of relative lateral and longitudinal movement, and a handle for actuating said shaft, said handle being capable of movement relative to said shaft, whereby the handle may return to normal position while the lock-pin is in raised posi tion.

3. In a device of the class described, the combination with a coupler-head provided with a lock-pin having an eye elongated in the direction of the length of the couplerhead, of a rock-shaft an arm carried by said rock-shaft and extending through said eye, whereby said arm and eye move vertically in unison but are capable of relative longitudinal movement resulting from the shape of the eye and relative lateral movement due to the movement of the arm through the eye, and a handle for actuating said shaft, said shaft being capable of movement relative to said shaft whereby the handle may return to normal position while said pin is in raised position.

In testimony whereof, I have hereunto set my hand and afliXed my seal.
