SAFETY-STOP FOR MINE-CARS.

Specification of Letters Patent.

Patented Mar. 20, 1917.

Application filed. December 8, 1916. Serial No. 135,738.,

I a car which, when used on slopes or inclines,

is provided with safety devices such that, if the haulage rope becomes broken, the car will be immediately stopped.

My invention comprises the novel parts and combinations thereof which are herein shown and described and then particularly defined by the claims.

In the accompanying drawings I have shown my invention in the form of construction which is now preferred by me.

Figure 1 is a side view of a car on a track, the parts being in the condition nor- 'mally occupied wherein the car is free to move in either direction along the track.

Fig. 2 is a side view of the same carwith the parts in the condition assumed when the haulage rope breaks and the safety devices are put into operation.

Fig. 3 is a top plan view of the car.

Fig. 4 is a transverse section of a car with the parts in the normal position, the

' plane of section being taken through one part of the wheel-receiving pockets formed in the sides of the car.

. The car body 1 is in the main of any ordinary or suitable type of construction. It has herein been shown as provided with longitudinal beams 2 placed beneath the floor and just inside of the wheels. These beams are preferably provided with a series of spurs or projecting metallic points 20, designed to engage with the ties of the track, or with a guard rail where such is used. In Fig. 1 1 have shown a guard rail 8, this being intended to be a wooden beam which is spiked to the ties a short distance inside of the rail 7. Where such a guard rail is used the spurs 20 of the car will engage this guard rail.

The car has axles 3 which are located substantially in the plane of the fioor and are mounted so that they may have an oscillating movement. They do not, however,

have any complete rotative movement. Upon the outer ends of these shafts are secured lever arms 4: which normally extend downward. Upon the lower or swinging ends of these lever arms are journaled the wheels 9 upon which the car travels. Upon the shafts 3 are secured controlling arms 5, these extending upward and preferably slightly forward. These arms are also preferably of somewhat greater length than the arms 4: which carry the wheels.

The haulage rope 6 is connected directly to the car. The connection is shown as having been made through the medium of a chain 60, but this connection is a direct draft connection and therefore, falls within the meaningof a direct connection, as the same has been used.

The upper ends of the two levers 5 at each side of the'car are connected to be operated together. This, as herein shown, has been done by means of a short rope 63, which has a turn buckle 64 connected thereto so that the length of this connection may be adjusted to thereby assure like connection for both shafts and the wheels carried thereon.

The forward set of levers 5 has a bridle 61 connected therewith and extending forward to a connection with the shackle 6a, which is included in the haulage connection. This bridle also is preferably provided with turn buckles 62, for accurate adjustment of its length.

The front ends of the car at each side are preferably provided with a rubbing bar 66, which has its ends 67 turned outward so as to prevent the bridle from being raised above the top edge of the car or depressed below the bottom edge, while it is under tension.

l Vhile in operation, the parts would be in the position shown in Fig. 1. The tendency of the car body to settle backward and to throw the wheels forward, is resisted by the tension of the bridle 61. If, however, this tension be removed, or considerably reduced in amount, as it would be if the haulage rope should break, the weight of the car body will cause a relative forward and upward movement of the wheels 9, or rather the car body would settle backward and downward, the wheels 9 enter the pockets 10 which are formed in the side of the car and are eovered by semi-circular bands 11. This is the condition of the parts as shown in Fig. 2. In this figure the longitudinal beams 2 of the car, have dropped upon the ties 7 O. The

spurs 20 which project from the bottom of these beams, will en age the ties in such manner.as to hold the car against further movement, even upon a steep incline. In some cases the use of such spurs may not be necessary.

Cars constructed after this manner thus provide an element of safety in their use, whereby they will be automatically checked and stopped upon the breakage of the haulage rope and accidents will in many cases be thus prevented.

lVhat I claim as my invention is:

1. The combination with acar body of levers pivoted upon the body and wheels journaled on said levers, a haulage rope and sepa ate connections from said haulage rope to the car body and to the said levers.

2. The combination with a car body, shafts journaled on the body, downwardly extending arms secured to the shafts, wheels journaled on the lower ends of said arms, controlling levers secured to the shafts and separate connections from said levers and from said car to the haulage rope.

3. The combination with a car body, shafts journaled on the body, downwardly extending arms secured to the shafts, wheels journaled on the lower ends of said arms, controlling levers secured to'the shafts, a haulage rope connected with the car body and a controlling member connecting the haulage rope with said controlling levers.

4. A car for operation on inclines comprising a body provided on its lower side with means for positive engagement with the track structure, wheels, lever arms pivoted upon the body and having the wheels journaled thereon, a haulage member connected with the car body and a controlling connection from the haulage member to said lever arms acting, when under strain, to maintain the car body in raised position.

5. A car for operation on inclines comprising a body, shafts journaled on the body, lever arms secured to the ends of said shafts outside the body, wheels journaled on the swinging ends of said lever arms, the body having pockets for the reception of the wheels and the lever arms when these swing upward, a haulage member and connections from said haulage member to the shafts acting to normally keep the wheels and their carrying arms down.

6. The combination with a car body, axles journaled thereon, lever arms fixed to the outer ends of the axles, wheels journaled on said arms, controlling arms also fixed upon the outer ends of the axles and extending upwardly, a haulage member connected with the car body, a bridle connected with the haulage member and with said controlling arms, said bridle containing means for adjusting its length.

7. A car for operation on inclines comprising a body, axles journaled thereon, wheel carrying arms secured upon the outer ends of said axles to swing outside of the car body, wheels on said arms, controlling arms also outside of the body and secured to said axles, and means for connecting said controlling arms with the car haulage member.

S. A car for operation on inclines, comprising a load-carrying body, wheels supporting said body and movable relative thereto, said body normally tending to drop automatically upon the track, and means actuated from the haulage connection for maintaining the body in raised position.

9. A car for-operation on inclines, comprising a load-carrying body having a bottom frame bar extending lengthwise thereof and provided with projections extending below its lower surface, wheels supporting said body and movable relative thereto, said body normally tending to drop automatically upon the track, and means actuated from the haulage connection for maintaining the body in raised position.

10. A car for operation 011 inclined tracks having a body, wheels, levers pivoted on the body and having the wheels journaled on one end thereof, a draft connection with the other end of the levers and a separate draft connection with the car coacting with said first draft connection.

Signed at Enumclaw, lVaslr, this 26th day of November, 1916.
