Serial No. 760,521.

To all whom it may concern Be it known that I, HENRY V. Fern. citizen of the United States, residing at Bick-l nellj in the county of Knox and State of Indiana, have invented certain new and useful Improvements in Means for Dumping Mine-Cars, of which the following is a specification.

This invention relates to mine car cages, and has special reference to means for facilitating the dumping of the mine cars and arresting the movement of the cars so that they will not roll from the platform of the ca e.

he object of the invention is to provide mechanism of a simple character which will automatically arrest the travel of the mine car when the platform is tilted so that the contents of the car may be discharged onto the dump while the car is retained upon the platform.

A further object of the invention is to provide mechanism for the stated purpose which will be compact and not apt to get out of order and which will not interfere in any way with the movement of the cage in the mine shaft.

While the invention is intended more es pecially for use upon mine car cages.l it is capable of use in other connections without material change.

The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features of the invention being subsequently particularly pointed out in the claims following the description.

In the drawings: Figure 1 is a side View of my improved mechanism showing it in the position assumed when the loaded car is being raised to the mouth of the shaft; Fig. 2 is a longitudinal section showing the position of the parts when the car is being dumped; Fig. 3 is an end elevation; and Fig. 4 is an enlarged perspective view of the improved mechanism,

The hoisting cage 1 is illustrated conventionally and in itself forms'no part of my invention and details of the guide rails and hoisting cables of the mine shaft have been omitted from the illustration for the sake of clearness in .the showing of the parts constituting the improvements.

In carrying out my invention, I provide upon the opposite side walls ef the cage a the cage and has its ends journaled in suitable bearings or castings secured to the same. The standards 5 are held in a fixed spaced relation by a cross bar or brace 7 and their upper ends are fitted upon a transverse rod or bar 8 which passes through the side beams of the platform and is extended beyond the same. The extremities of this rod are equipped with rollers 9 which may ride in ways or guides 10 in the-mine shaft or may be easily grasped by the persons operating the platform at the dump', so that the same may be swung away from and to the cage, as will be readily understood.

The platform 2 is provided upon its upper side with track rails 12 which are adapted' to aline with the rails of the track within the mine tunnel so that the loaded car, indicated at 13, may be readily run onto the platform.

rIhe upper surfaces of these track rails 12 are.

provided at the proper points with slight depressions or notches 111 into which the wheels of the mine car may seat so that the car will be held against travel when the cage is being raised or lowered. To the outer sides of these track rails, at the ends of the same, I secure brackets 15 which are offset from the rails at their inner ends, and between the said offset ends and the rails are pivoted links 16 which have their innery ends pivoted to the upper ends of stop or brake bars 17. These brake bars or stops 17 extend downwardly through longitudinal slots 18 formed in the platform immediately adjacent the track rails and have their lower ends pivotally secured within the longitudinal slots 19 of the arms 5.

When the cage is lowered within the shaft and is at the mouth of a mine tunnel, the platform 2 will be supported in a horizontal position so that the track rails thereon aline with and form practically continuations of the track rails within the tunnel. One end of the platform will be supported in this position by the rollers 1 engaging the lower `side of the shaft.

walls of the guides 3 and resting against one closed end of the guide, while the opposite end of the platform will be supported by the standards 5, as will be readily understood on reference to Fig. 1. In this position of the parts, the brake bars or stops 17 will 'be inclined inwardly with respect to the cage s0 that the inner ends of the links 16 will be drawn downwardly and the said links will lie below the surface of the track rails so that they will offer no obstruction to the movement of the car onto the platform. Consequently, a car may be rolled onto the platform from a tunnel at either After the car has been rolled onto the platform and its wheels engage the notches 14 therein, the cage is raised to the mouth of the shaft in the usual manner and at the mouth of the shaft 'the'platform is tilted outwardly and downwardly,-thereby causing the standards 5 to swing to the position shown in Fig. 2. As the' standardsl are thus moved outwardly andl downwardly, the outer ends of the brake bars or stops will be caused to move' away from the side of the cage, and, as thei upper ends of the said bars-tend to follow the movement of the lower ends thereof, thev links'16 will be caused to swing upwardly about their pivotal connect-ions with the brackets 15 to the position shown in Fig. 2 and in Fig. 4, thereby raising the upper ends of the brake bars so-that they will extend across the path of the car wheels or the aXle upon which said wheels are mounted,`

whereby the movement of the car toward the lower end of the tilted platform will be arrested and the car prevented from rolling' from the platform. l The platform will be prevented from swinging entirely free of the cage by the rollers 4L engaging the adjacent closed end of the guides 3 and thereby' limitingthe movement of the platform, as

. will be readily understood on reference toA Fig. 2.

- When the contents of the car have been entirely discharged, the platform is returned to its normal position, and, as it assumes said. position, the supporting standards will swing toward the cage so that the stopor Y brake bars will be drawn to their initial positions below the tread surface of the track rails and the links drawn down to the platform sothat no obstruction to the movement of the car from the platfo-rm will be offered.

. It will be readily noted that my improved mechanism is very simple and compact and My improved apparatus may be applied to any mine car cage without necessitating a reorganization thereof. The usual keepers which engage between the car wheels may be retained and are indicated conventionally at 20 and my device will be found an efficient adjunct thereto. These keepers 20 are arranged to swing automatically over the track rails between the car wheels as the cage starts to rise from the bottom of t-he shaft and they are intended to hold the wheels in their seats 'as the platform tilts to cause the car to dump. It frequentlyhappens that, becausev of wear, the keepers escape the treads of the wheels which then leave their seats, as shown in Fig. 2, and are positively arrested by the stop bars 17. As the platform tilts7 the said stop bars rise to a position immediately adjacent the car wheels so j that a very slight movement of the car wheels will bring them against the stop bars support for one end of the platform,- a

swinging support for the other end of the platform, and stops actuated by the swinging support to project above the platform when the platform is tilted.

2. The combination with a hoisting cage, and a tiltable platform, of a rolling support for one end of the platform, aV swinging sup-` port for the other end of theplatform, stops attached to the said swinging support and extending through the p-laftform, and means on the platform for lowering the said stops to the platform in the normal posit-ion of the same and raising the stops above theplatform as the platform is tilted. I

3. TheV combination with a mine car cage, of guides on the sides of the cage having closed ends, a platform arranged between the sides of the cage, rollers at one end of the platform engaging said guides, and a swinging support for the other end of theY platform mounted on the cage.Y

Ll. The combination with a hoisting cage, of a platform disposed between the sides of the cage, means at one end of the platform to prevent release of the plat-form from. the cage, a support for the other end of the platform pivoted to the sides of the cage,

stops pivoted to said support and rising .through the plat-form, and links pivotedof a tiltable platform arranged within the cage and provided with a longitudinal slot, a Swingin standard pivoted below the platform within t-he cage, a Stop pivoted to said standard and rising through the slot in the platform, and a link pivoted at its outer endk platform, and movable car-arresting means connected with the tiltable support and the platform whereby the tilting of the platform will cause said car-arresting means to extend into the path of a car on the platform.

In testimony whereof I affix my signature in presence of two witnesses.
