Specification of Letters Patent.

Be it known that I, Jiuirs' J. .l'IAXXUN, a

tion'. as will be readily understood. I shall citizen of the United States, residing at Logansport, in the county of (lass and State] off-Indiana. have invented certain new and useful Improvements in Uncoupling-Levers,

:of which the following is a specification.

In the drawings: Figure 1 is an end view ofa car end sill, broken away. with my invention in position. view ofthesame. Figs. 3 and 4 are top plan views of the levers detached. Figs. and 6 are top plan and end elevation, respectivel'y, of one ofthepivot plates. Figs. 7

and 8 are similar views of another pivot platef 1 represents a car of approved construe tion having an end sill'2 constructed of coin- Of course any type of end sill may be employed as far mercially' rolled. channel iron.

as my invention is concerned.

3 is a coupler of approved type.

i a plate having an offset at one end which'terminates in a pivot bearing 0. The

5 offset and pivot hearing are deflected downward as clearly shown in the several views in the drawing so that they willbe in a horizontal plane below the top of the end sill. The plate 4 is provided with rivet or bolt openings through which bolts or rivets are passed whereby it is rigidly secured to the flange ofthe channel iron.

The plate 7 is provided with openings to facilitate its attachment to the flange of the channel iron. This plate is provided with an olfset 8 about midway its length, from which projects a pivot bearing 9. The offset and pivot bearing 8 and 9 are deflected downward and thence outward as explained in connection with the offset and pivot bear ing of the plate 4. 10 is the pin of the coupler having an eye in its head.

11 is a lever pivoted on the pivot bearing 9 of the plate 7 whereby it is pivotally mounted on the 'end sill of the car. This lever has an offs 6t 12 and an extension 13 whereby it is positioned in line with the eye of the coupling pinthe extreme end of the portion 13 being reduced and rounded as at 14 whereby it may readily slide, or rather the pin may slide on it as the draw bar swingsfrom side to side of the car in round ing curves and its general movement in ir Fig. 2 is a top plan Patented Feb. 22, 1919.

' Application filed July 19. 1907. Serial No. 384.546.

.p(' rtion 13 being turned up as at 15 to prevent the pin lipping oil said rounded porior sake of brevity refer to the portions 1 1, 1-2, 13, as the uncoupling lever in the specification and claims.

The outer end of the uncoupling lever is deflected downward and slightly outward as zit-1G and provided with a hook I? which is turned inward toward the end sill as clearly shown in Fig. 2. p

18 is a hand operated lever pivoted on the pivotal bearing 6 to the end sill some distance from the pivot of the uncoupling lever toward the side of the car, theend 19 of which is bent downward and thence upward in a gentle curve with its extreme end in about the same plane as the center of the pivot pin 6. The outer end of the hand lever is sagged downwardly below the plane of the undenface of the end sill, in which position it may be readily grasped by a trainman ewithout danger of having his hand caught between the end sills of adjacent cars.

My improved release sagging or uncoupling release is dcsigned to be operated by raising up on the lever 18 which causes its end 19 to swing downward in an arc and as the-end 19 is in engagement with the hook 17 of the uncoupling lever said lever is swung on its pivot 9 and its inner end elevated wherebythe pin 10 is raised and the uncoupling efiected.

It will be seen that the levers have no rigid or fixed connection between them thus they may, independently take up the usual movements of a car in transit without afl ecting the coupling.

It will be noticed that the uncoupling lever is pivoted beyond its center toward the side of the ear. thus placing the greatest weight between its pivot and the coupling pin, the object of which is to obviate the accidental uncoupling of the cars while in transit, due to the vertical movement of the lever incident to the movement of the train. It has been found that with the weight of an independent lever like this disposed equally, or nearly so, of its pivot, it has a tendency to jolt upward, thus uncoupling the cars while .in transit, which may result in destruction .of life and property. For this reason I dispose the greatest weight of the lever on the coupling pin.

regularities in the road bed. The end of the As will be seen in Fig. 2, the major portion of the hand operated lever 18 is deflected toward the end sill so as to prevent the hand levers of coupled cars engaging or interfering with each other on curves.

The outer end of the hand operated lever is limited in its downward movement by means of its hook 2O engaging the uncoupling lever:

It will be understood that my uncoupling lever can be operated by a person standing on the end sill, over the rigging, by placing the foot on the end of the lttYQl. which is connected with the draw bar and pushing down. When cutting a car oil' from a train, this will be found a great advantage, as it will avoid the necessity at times, of having to hang over the side of the car to make the uncoupling.

What I claim is-- 1. In a release rigging for cars, the combination Withan uncoupling lever pivotally mounted and having a downward sagging outer end, and a hook on said sagging end, of a hand operated lever independently pivoted and a hook on its inner end constructed to engage the uncoupling lever while the hook ofthe uncoupling lever is constructed to engage the hand operated 2. In a release rigging, the combination with a commercially rolled channel iron end sill, of a plate secured to the flange thereof, and apivot bearing extending downward and thence forward from said plate,

3. In a release rigging,,the combination with an end sill of commercially rolled channel iron, two pivot plates secured a distance apart to the upper flange of said iron, of an uncoupling lever pivotally mounted on one of said pivots, a hook depending from. the outer endof said lever, the inner end of this lever being reduced in diameter, and a hand operated lever independently mounted on the other pivot, the inner end of the hand lever being bent downward and thence upward, a hook on the inner end of the hand lever, the outer end of said hand lever being sagged'downward below the under face of the endsill, the hook of each lever being c0nstructed to engage theother lever.

In testimony whereof I afilx any signature in presence of two witnesses.
