ers; and I do hereby declare that thefollow- 1 ing is a full, clear, and exact description thereof. 7

This invention relates to pin lifters and is particularly directed to a device for lifting coupling pins of railway cars.

In pin lifters, as heretofore constructed, it has been customary to provide" a rock shaft coupled by means of a link or chain .with the pin and having a crank arm by. means of which it may be operated. These arms re quire a considerable effort for their proper manipulation, particularly so after they have become slightly rusty. It is usually necessary for the'brakeman to stand between the adjacent cars in order to secure the proper grip upon these crank arms. This, as will be appreciated, is a precarious position, and it frequently happens-that inadvertently the brakeman is forced against the outwardly projecting arm, or otherwise injured when the cars come together. This invention is designed to provide a pin lifting.

device which avoids all of the above noted defects and insures the safety of the operator.

Objects of this invention are to provide a pin lifter which mayv be operated by a man standing to the side of the railway car, which is operated by a direct pull rather than by a rocking motion, and which is so arranged that the brakeman will fall away from the car if he should slip, and therefore be out of the danger zone.

Further objects are to provide a pin lifter which is of simple design, which is sturdy and reliable in operation, and which may be produced at a minimum cost.

An embodiment of'the invention is shown in the accompanying drawings, in which:

Figure l is a fragmentary end view of a railway car equipped with the pin lifter.

Figure 2 is a side elevation ofthe pin lifter, partly in section.

Referring more particularly to the drawings, 1 indicates a railway car, 2 a coupling, and 3'the coupling pin. A lever A, conveniently in the form of a round bar, has an eyelet 6 at its inner end which is pivotally mounted upon a pin 5 carried between the secured'to the face of the car. This lever has a rounded intermediate portion 9 andan outwardly projecting arm 10, such arm being passed through the eyelet 11 of the pin 3. A transversely slida-ble rod 12 is carried by a pair of guide brackets 13 and 14 and is provided with a downwardly projecting operating-handle 15 adjacent the outer edge of the car and may be conveniently provided with a stop 16 adapted to abut against the guide 14 when the rod occupies its dotted line position.

The inner end of the rod is provided with a bracket 17 which, by means. of a pin 18, is pivotally joined to a link 19. The upper end of the link is provided with an eyelet 20 which engages the rounded portion 9 of the lever 4L.

outwardly projecting ears? of a bracket 8 In operating this vdevi'ce 'the brakeman stands to the side of the car and is not required to stand between adjacent cars as has heretofore been the case. to lift the pin he pulls the handle 15 outwardly into the dotted line position, thereby forcing the link 19 against the rounded portion 9 of the lever 4 and causing such lever to move to its dottedline position, as shown in Figure 2, thereby lifting the pin 3.

It is to be noted that the operator manipulates this device by a direct outward pull When he desires and that he is at all times out of the danger zone. It is also to be noted that even in the event of the operator slipping, he will fall In other words, these pin lifters may be directly attached to the body of thecar in i an extremely simplemanner and, due to the relatively elongated. arm 10, will cooperate with any-type of the usual coupling pins.

I claim 1. In combination, a railway car body provided with a coupling having a coupling pin,

a bracket mounted on said car body, a lever extending outwardly at right angles to the plane of said car body and carried by said bracket and having its outer end connected 90 away from the cars and. not between them.[

with said pin, a rod slidably mounted in guides secured to said car bodyand having a manipulating handle laterally spaced from said coupling, and an angularly arranged link connecting said lever and said rod and lying in a plane substantially at right angles link pivotally joined to said rod and to an intermediate portion of said lever and lying in a plane at right angles to the plane of said lever, whereby when said rod is slid longitudin'ally, said lever is elevated, thereby is raising said pin. o

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of WVisconsin. f
