FRANK OSHA, OF LINTQN, INDIANA.
AUTOMATIC BUMPER FOR USE IN COAL-MINING.
SPECIFICATION forming part of Letters Patent N 0. 768,681, dated August 30, 1904.
Application filed February 27, 1904. Serial No. 195,697. o modeh I To all whom it may concern.-
Be it known that I, FRANK OSHA, a citizen of the United States, residingat Linton, in the county of Greene and State of Indiana, have invented a new and useful Automatic Bumper for use in Coal-Mining, of which the following is a specification.
My invention relates to improvements in coal-mining which I denominate an automatic bumper, which operates in oonpinction with a hoisting-cage 1n the shaft of a coal- .mine; and the object of my invention is to provide for the prevention of coal-cars loaded in the mine from running into what is known as the sump under the cage, upon which the cars are hoisted to the top, and to prevent the cars from running into said place when the cage is at the top.- I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top view of the entire machine, together with the cross-ties, iron rails, cage, and bottom of the shaft. Fig. 2 is a side view of the automatic bumper and its attachments, together with the side view of the track upon which the coal-cars are run upon the cage when lowered. Figs. 3 and 4 are elevated end views of the entire bumper, together with track over which the cars are run and the various attachments of the bumper. Fig. 3 shows the position of the automatic bumper when the cage is down at the bottom. Fig. 4 shows the position of the bumper when the cage has been raised or hoisted to the top.
Similar letters refer to similar parts throughout the several views.
The letter A refers in Fig. 1 to the curved iron shaft-or automatic bumper leading from its attachments to the side of the track D, where it is attached by bolts to permit the end of the bumper A to move upon and off the track on which the cars, loaded with coal, are run toward the shaft. B in'said figure shows the iron arm attached to the post C, with bolt on said post at a, and hinge attachment to bumper at Z), upon which arm a heavy iron weight 11 is attached.
To the shaft of the bumper A at c is a chain which extends from '0 to a sheave-wheel at H, which sheave-wheel is attached to the end of {a long tie and extends from the track over which the cars are run, and said sheave-Wheel is attached by bolt (Z, which chain I passes around said sheave-wheel and extends to another sheave-wheel attached to the bunting F, that crosses the shaft at the bottom thereof, which sheave-wheel is designated byG and is attached by bolt 6, which chain is attached to cross-bar E, which cross-bar runs parallel and is attached to the bottom of cage-seat at I, which bar E is made of iron, and the attachment of said chain is indicated by J in Fig. 1 represents the track and iron rails over which the cars are run.
K represents the cage lowered.
Fig. 2 shows a car-wheel in position at L and gives a side view opposite the side upon which the automatic bumper works, which shows the post C, to which is attached the arm at a, on which the heavy iron weight 2' is attached.
Figs. 3 and 4: show the automatic bumper out of position and in position. respectively. It will be observed when the heavy cage descends the shaft of a coal-mine and strikes upon the ironbar at E, attached to the bottom of a cage-seat at I with bolt and at the other end attached to the chain at f, the automatic bumper is drawn from over the iron rail and track by the weight of the cage, which strikes the same, and when the weight is lifted from the iron bar E the heavy weight attached to the iron bar B will automatically throw the curved bumper in position on the track to receive the car-wheel of the loaded coal-car and prevent the same from running into the bottom-of the shaft, the position of the car-wheel and bumper being shown in Fig. 4.
What I claim as my invention, and desire to secure by Letters Patent, is'
1. The automatic bumper consisting of a curved iron shaft which is attached as herein substantially set forth together with its attachments consisting of an iron arm attached to C at a on the end of which iron arm is a heavy weight 5; the other end of which arm being connected and attached to the bumper at b and works on the principle of ahinge.
2. In an apparatus of the class described,
the combination With a mining-shaft and a track leading thereto, of a pivoted bar E at the bottom of the shaft, a Weighted lever B pivotally supported by the side of the track at a distance from the shaft, a pivoted laterally-swinging bumper-arm by the side of the track and connected to said Weighted lever, and a chain or cord connecting the bumperarm to the pivoted bar E, substantially as set forth.
3. In a device of the class described, the combination with a mining-shaft and a track leading thereto, of a movable bumper by the side of the track, means for normally moving said bumper over the track, a movable part in the shaft adapted to be depressed by the cage, and means connecting this movable part with the bumper, for the purpose set forth.
4L, In an apparatus of the class described, the combination with a shaft and a track leading thereto, a depressible device in the shaft adapted to be depressed by the cage when at the bottom of the shaft, a bumper adapted to be shifted into the path of the cars on the track, and means normally raising the depressible device in the shaft and shifting the bumper into the path of the cars, for the purpose set forth.
