CAGER AND SUMP-GUARD.

Specification of Letters Patent.

Patented Aug. 17, 1909.

Application filed February 11, 1909. Serial No. 177,288.

To all whom it may concern:

Be it known that I, GRANT HOLMES, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Cagers and Sump- Guards, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to cagers and sump guards, and is designed more particularly for use in connection with car handling mechanism such as is employed in coal mines and similar places.

The object of the invention is to provide a movable stop to prevent the following car from bumping into the car standing upon the eager; to so arrange this stop that the movement of the same will be automatically controlled by the movement of the eager; to

provide means for supporting the eager normally in its closed position; and to provide sii'i le operating means for actuating the ca er, sump guard and movable stop.

With these objects in view my invention consists in certain novel features and in certain combinations and arrangements of parts hereinafter to be described, and then more particularly pointed out in the claims.

In the accompanying drawings, Figure l is a top plan view of a eager and a portion of a track embodying my invention; and Fig. 2 is a side elevation of the same.

In these drawings I have illustrated one embodiment of my invention and have shown the same in combination with a main track 1 and a eager 2 arranged between the main track and the shaft 3 within which the eager operates. This eager may be of any suitable construction but I have, in the present instance, shown the same as consisting of a rail section which is pivotally supported and has those portions lying on the opposite sides of its pivotal center extending at an angle one to the other, whereby, when that portion of the rail section lying on one side of its pivotal center is in a substantially horizontal position, that portion of the rail section lying on the other side of the pivotal center will extend upwardly at an inclination to the horizontal portion of the rail section. This rail section preferably comprises two rails forming continuations of the main track, which ails are rigidly secured to a shaft 4 which is journaled in bearings 5 mounted on a sill or supporting base 6. The main track 1 and the sill or supporting base 6 for the eager preferably slope downwardly toward the shaft 3, thus causing the cars to move automatically toward the shaft.

In order to maintain the eager in its closed position, 2'. 6., with its rear end, or the end next to the shaft, elevated to prevent the passage of the car from the eager, I have provided an operating means therefor com prising toggle links 7 connected at one end to that portion of the eager lying between the pivotal center thereof and the shaft and rigidly connected at the other end to a shaft 8 mounted in suitable bearings 9 carried by the sill or supporting base 6. There are preferably two pairs of these toggle links, one connected to each of the rails of the eager. A suitable stop is provided to pre vent the toggle links from moving past their central point in one direction. This step is here shown as consisting of a chain 10 con nected at one end to one of the links 7 and at the other end to the sill 6. An operating handle 11 is rigidly secured to the shaft 8 at one side of the eager and serves to rotate theshaft 8, whereby the toggle links 7 are broken or moved into alinement and the eager moved about its pivotal center in one direction or the other. lVhen the eager is in its closed position the toggle links will be arranged in alinement one with the other and will form a rigid support for the rear end of the eager, thus positively retaining the same in its closed position regardless of whether or not a car may have passed on the forward end thereof. Suitable means are provided for preventing the following car from passing off-the rear end of the main track before the forward portion of the eager has been moved into its horizontal position. To this end a sump guard, preferably comprising a segmental plate 12, is secured to the forward portion of each rail of the eager and has its curved face arranged in alinement with the rails of the main track. This segmental plate is preferably secured to the lower flange of the rails by means of bolts or rivets 13. Thus, when the eager is moved about its pivotal center to discharge the car therefrom the sump guard 12 will be moved into a position in alinement with the ends of the rails of the main trackand will engage the wheels of the following car and prevent the same passing from the main track until the eager has been moved into a position to receive the same.

It is also desirable to provide means for preventing the following car from bumping into the car standing upon the eager and to this end I have provided a movable stop which is supported near, that is, in operative relation to, the main track at some distance from the end thereof and is adapted to be moved into position to engage the wheel or some other part of the ear and prevent its further movement. In the present instance I have shown this stop as comprising a plate or arm 14; rigidly secured at one end to a shaft 15 which is preferably journaled in bearings formed in the rails of the main track 1. There are preferably two of these stops or plates 14:, one arranged on each side of the track and adapted to engage the adjacent wheel of the car truck. The forward ends of the plates or arms 14; are bent inwardly to form flanges 16 which extend into recesses 17 formed in the adjacent sides of the rails of the main track. These reeesses not only permit the stops to extend squarely into the path of the wheels of the car, but also form guides for the stops, and the forward or flanged ends of the stops are curved to facilitate their movement in the slots 17. These stops may be operated in any suitable manner, but it is desirable that they should be operated in unison with the eager, and, to this end, I have rigidly secured to the shaft 15 a crank arm 18 which is connected by a rod 19 to a similar crank arm 20 which is rigidly secured to'the shaft 4: upon which the eager is supported. The

crank arms

18 and 20 extend in opposite directions, and, consequently, when the eager is moved about its pivotal center in a direction to move the rear portion of the eager into a substantially horizontal position and thus discharge the car therefrom, the stops 14; will be moved into their lowermost or inoperative positions and the car permitted to move forward until it engages the sump guard 12 which has been elevated by the movement of the eager. When the front wheels of the car are -in engagement with the sump guard 12 the rear whels will have passed beyond the forward ends of the stops 14. Consequently, when the eager is returned to its closed position, with the forward end thereof in alinement with the main track, the ear is free to move onto the eager and the stops 14 are free to move upward into a position to engage the wheels of the following car. It will be obvious that this stop may be mounted either in the main track or in an extension of that track. In the present instance I have shown the rear end of the main track as provided with special rails within which the shaft 15 carrying the stops is journaled, these rails forming a part or continuation of the main track.

The o eration of the device will be obvious from the foregoing description and it will be apparent that i have provided in combination with the eager a stop which serves to: prevent the following car from bumping into the car standing upon the eager and thereby eliminates the possibility of the coupling mechanism or bumpers of the ear overlapping and interfering with the operation of the eager; that this stop is operatively connected to the eager in such a manner that the movement of the eager will automatically move the stop into or out of its operative position; that the operation of the handle 11 will serve to simultaneously actuate the eager, sump guard and the stops; and that the toggle links 7, forming part of the actuating mechanism for the eager, also serve as a positive lock to retain the eager in its closed position in the absence of a car therefrom.

I wish it to be understood that I do not desire to be limited to the details of construction shown and described, for obvious modifications will occur to a person skillet in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is 1 1.
