LOCKING-PIN-LIFTING MECHANISM FOR CAR-COUPLINGS.

To all whom it may concern:

Be it known that I, ELI H. JANNEY, a citizen of the United States, residing at Alexandria, in the State of Virginia, have invented new and useful Improvements in Looking-Pin-Lifting Mechanisms for Car-Couplings, of which the following is a specification.

My invention relates to devices for lifting the locking pins of car couplings, and has for its object to provide certain improvements in the construction of the same as will be hereinafter more definitely pointed out and claimed, reference being had tothe accompanying drawings, in which- Figure 1 is a perspective view of a portion of the end sill of a car showing my improved lifting mechanism in connection with a coupling of the Janney type. Fig. 2 is an enlarged top plan view of the car sill with the pivot guide for the lifting arm in position thereon. Fig. 3 is an enlarged detail perspective view of my improved lifting arm. Fig. 4 is an enlarged vertical transverse sectional view of the car sill taken centrally of the pivot guide, the lifting arm being shown therein in side elevation, and the locking pin of the coupling being shown partly in section. Fig. 5 is an enlarged detail perspective view of a slightly modified construction. Fig. 6 is a sectional view on the line VII-1 H, Fig. 4. Fig. 7 is detail sectional view on the line VIITVIII, Fig. 2, the lifting bar being also shown thereon in section. Fig. 8 is a detail transverse sectional view through the lifting bar, the inner end of the lifting lever being shown in full lines in the act of contacting therewith to lift the same, and the parts being shown in dotted lines in the lifted position. Fig. 9 is a transverse sectional view of the upper end of the locking pin, the lifting bar being shown in full lines thereon in the act of lifting said pin.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawings, referring more particularly to Figs. 1 to 4, the reference numeral 1 denotes a draw-head of the J anney type, in which is located a vertically movable locking pin 2. Fixed to the sill 3 0f the car by means of bolts 4 is my improved pivot guide 5, the same consisting of a substantially flat plate 6 supported at its ends upon Specification of Letters Patent.

cross pieces 7 formed integral therewith and projecting to each side to receive the bolts 4. Said plate is slightly higher at its transverse center than at its ends, as seen in Fig.4, and is provided on each side of said central portion with ears or lugs 8 having formed integral therewith downwardly projecting feet 9 through which pass the retaining bolts 4, said feet 9 and cross pieces 7 thus supporting the plate 6 raised from the sill 3. Said plate 6 is preferably projected slightly beyond the front edge of the sill, as seen in Fig. 4, and is slotted centrally and longitudinally at 10, said slot extending at its front slightly beyond the front edge of the sill 3, as shown.

Removably located, as hereinafter de scribed, in the slot 10 of plate 6 is a flat lifting bar 11 having side webs 12 adapted to rest on the upper surface of plate 6 on either side of the slot 10, said bar 11 being curved slightly to conform to the upper surface of plate 6. The rear downwardly turned end 13 of said bar 11 is provided with laterally extending pintles 14 having flat under surfaces 15, and slightly inclined upper surfaces adapted to engage the under side of plate 6 on each side of the slot 10 therein. The front downwardly turned end 16 of said bar 11 is also provided with rounded pintles 17 slightly inclined on their upper surfaces and adapted to detachably engage the locking pin 2, as hereinafter described. A lever 18 for operating said lifting bar 11 is pivoted at 19 to the sill 3, said bar preferably dropping on the inner side of said pivot to provide additional weight on that side of said pivot to insure a normal downward position to the inner end of said lever, which is liinited by a stop pin 20. The inner end of said lever, which extends beneath the lifting bar 11,'is provided with an angle bend at 21 so that said inner end will clear the front projecting end of the plate 6.

The lifting pin 2 to be operated is slotted at 22 in its upper rear face, said slot extending to the top of said pin. Corresponding slots 23 and 24 are also provided in the side faces of said pin opening into the rear slot 3 22, said slots 23 and 24 being curved forward at their upper ends at 25 and curved backward at their lower ends at 26, and said .slot 23 being slightly higher than slot 24, as

seen in Fig. 9, for purposes hereinafter to be described.

By referring to Fig. 7 it will be seen that the under side of plate 6 on opposite sides of the slot 10 is inclined slightly downwardly and outwardly in opposite direc tions, to conform to the slight taper of the pintles 14, for a purpose hereinafter to be described. 7

To assemble the parts the lifting bar 11 is first turned to a right angle horizontally to its normal position, in which position the pint-les 14 thereof may be inserted into the slot 10 of plate 6. Upon then turning the front end of said bar to its normal position said pintles will be retained in the position shown in Figs. 1 and 4:. To connect the lifting bar and the locking pin 2 said bar is lifted at its front end, and said locking pin turned to a horizontal position so that the pintles 17 on said bar may enter slot 22 in said pin. The pin may then be turned again to its vertical position and said pintles 17 will enter and engage in the slots 23 and 24., thus locking the parts against separation. The pin 2 being new inserted in the draw-head 1, the parts are in position for operation.

With the pin in its locking position, as shown in Fig. 1, the depression of the outer end of lever 18 will cause its inner end to contact with the under side of lifting bar 11, and because of the inclined upper surface of said. inner end of said lifting bar, this initial contact will be with the edge of the left hand web 12 of said bar, the result being that said bar 11 will be initially tilted slightly to the left and as the slot 24 in pin 2 is slightly lower than slot 23, as seen in Fig. 9, the left hand pintle 17 so tilted with bar 11 will first contact with the upper end of slot 24, and in lifting the pin 2 will tilt the lower end of the latter to the left, thereby causing said looking pin to clear the anti-creeping device (not shown) located in that side of the draw-head 1 opposite to its coupling hook. Now, as the inner end of lever 18 is lifted further its upper edge will gradually contact with the whole under surface of bar 11, and upon a still further lift, to raise the pin 2 to the couplin hook opening posi tion, will contact with the right hand rib 12 alone, thereby tilting bar 11 in the opposite direction, and causing a contact between both of the pintles 17 and the upper edges of both slots 23 and 24 in pin 2, whereby said locking pin 2 will be tilted to the right at its lower end and will thus tend to follow the coupling hook tail in its opening movement. By inclining the under side of the plate 6, as shown in Fig. 7, to conform to the incline of the pintles 1st I provide what may be termed a universal bearing for said pintles under this slight tilting in either direction hereinbefore described.

By providing the elongated slot 10 in the plate 6 in which the rear end 13 and pintles 14 of the lifting bar 11 move, I provide for any longitudinal movement of the drawhead 1 within the limits permitted by the draft rigging, and also provide for the limited longitudinal movement of the lifting bar 11 under the pin lifting movement. liurthermore, the construction readily accommodates itself to the free lateral movement of the draw-head and draw-bar in rounding curves.

By reason of the slotted connection between the lifting bar 11 and locking pin 2, said lifting bar will be raised from its lowermost position only when lifted by lever 18, and, when released thereby, will at once assume its lowermost position, even though the locking pin 2 be raised to the lock-set position. Thus there will be at no time any permanent lifting of pin lifting mechanism, nor will said mechanism be affected by any movement of the locking pin 2, as when the latter is lifted by the coupling hook tail in either its opening or its closing movement its vertical movement will not affect said lifting bar 11. Furthermore, when used on flat cars the load may project over and rest on said lifting bar, and the locking pin 2 can still be operated from beneath the draw-head.

It will also be observed that in the preferred construction both the connection between the lifting bar 11 and the plate 6, and the connection between said bar and the locking pin 2 are detachable connections of integral parts, whereby the use of separate connecting devices, such as pins, is dispensed with.

The function of the upper forward curve 25 of slots 23 and 24: in the locking pin 2 is to cause the pintles 17 of lifting bar 11 to contact with said locking pin, while iii?"- ing the same, forward of the center of gravity of the latter, so that the lower end of said locking pin will be tilted forward, in order, when rel ased, to engage the lockset seat in the draw-head 1, which in my type of couplings is located in the front of the draw-head. The function of the lower rearward curve 26 in said slots 23 and 24 is to provide for a limited backward and forward movement to the locking pin 2 when raised to the lock-set position and being operated by the coupling hook tail in either its opening or closing movement.

A particular advantage gained by curving the upper and under sides of the plate 6 and similarly curving the lifting bar 11. is to reduce the friction between lifting bar 11 and plate 6 to a minimum. Thus, as seen in Fig. 1, the pintles 14- of bar 11 lie against an up curve of the under side of plate 6,

and its slight forward movement under a lift of said bar and the locking pin 2 is thereby facilitated and any binding tendency prevented. Further, when said bar 11 is released and drops to its initial position, said pintles are aided in their rearward movement by the curve of the under side of plate 6.

By means of the pivotal connection between the lifting bar 11 and plate (3, said bar will at all times lie in a substantially longitudinal line with the center of the draw-head under any lateral movement of the latter, so that said bar is always in a position to lift the locking pin 2 vertically.

The object in inclining the under side of plate 6 downwardly in front and rear of its longitudinal center is to cause the pintles 14- of lifting bar 10 to more readily reassiune their normal central position with respect to said plate, and without any binding, under the jerking backward and forward movement of the draw-head 1 when cou pled in a movingtrain.

By providing the pintles 14: with flat un der surfaces 15 any longitudinal movement of the lifting bar 11 in the pivot guide 5 will tend to scrape out any accumulation of dirt or ice on the car sill 3 beneath the plate 6, while the sharp front and rear edges of the ribs 12 of lifting bar 11 will perform the same function On top of said plate 6.

In Fig. 5 I have shown a somewhat modified construction, wherein the connection between lifting bar 11 and locking pin 2 is formed by ears 27 on said locking pin re ceiving therebetween the outer end of lifting bar 11 the parts being pivotally connected by bolt 28. In this construction, however, said lifting bar must always move with the locking pin 2 Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a locking pin lifting mechanism for car couplings, the combination with a slotted locking pin, said slot lying normally within the draw-head, of a lifting bar directly and pivotally connected to said locking pin through said slot in such manner as to permit an operative vertical movement to said locking pin without movement of said lifting bar.
