ENDLESS-ROPE HAULAGE.
Specification of Letters Patent.
Patented Apr. 22, 1913.
Application filed October 17, 1907. Serial No. 397,912.
To all whom it may concern Be it known that I, JAMES WVILLIAM SMALLMAN, a subject of the King of Great Britain and Ireland, of Nuneaton, in the county of \Varwick, England, have invented new and useful Improvements Relating to Endless-Rope Haulage, of which the following is a specification.
In endless rope haulage, if the rope break, or accidents happen to couplings or clips, considerable damage may result from tubs running away. It is usual to guard against tubs that are being hauled uphill running back very far should they become accidentally released. Owing to such tubs if released reversing their direction of travel, no difliculty presents itself; for ordinary detents (monkeys) fixed every ten yards or so and tripped by the axles of the hauled tubs act quite effectively as stops. Tubs that are being held back downhill, if accidentally released, do not however change their direction of travel; and consequently ordinary detents (monkeys) can not be applied. It is therefore customary for tubs working downhill to be left unguarded against accident.
The primary object of my invention is to provide a device that will allow a tub going down hill to pass at the ordinary speed (about two miles an hour); but will stop the tub at a runaway speed.
I prefer to carry out this invention by employing a special detentthat is only moved to a certain degree by contact with each axle of a tub traveling downhill at the working speed; but which under the impact due to the velocity of a runaway tub is fully tripped or turned over center by one axle so as to engage with the other axle and serve as a stop.
Reference will now be made to the accompanying drawings.
Figure 1 is a side elevation of a device that permits tubs going downhill to pass at the working speed but stops a runaway tub. Fig. 2 is a corresponding front elevation. Fig. 3 represents the special detent separately. In Fig. 4, the bracket is in section on the line as (Fig. 2). In Fig. 5, the two axles of a tub are shown in section; the first axle having (at the working speed) just depressed the head of the special detent. In Fig. 6, the special detent has been turned over center by a blow from the first axle of a runaway tub.
A is the preferred pattern of detent. This detent has a head Z) and a wide hook c. The bracket D is bolted to a sleeper or frame. The abutments e and e on the bracket D are for the hook c to rest upon when the detent A is in its normal position.
' f and f are supports on the bracket D for the hook 0 when the detent A is turned over center.
G is the joint-pin retained by a split cotter h.
J is the first axle of a tub traveling in the direction of the arrow 7 J being the second axle.
K and K are two of the wheels running on the rail L.
At the proper speed of the tub, the axle J gradually depresses the head 6; the detent A returning to its normal position under the influence of gravity. The detent A, during the passage of the axle J, again rocks'idly. But the axle J of a runaway tub strikes the head 5 with sufficient force to fully trip the detent A. The hook c then beds against the supports f and 7, receives the axle J and stops the tub.
hat I claim as my invention and desire to secure by Letters Patent is:
1. In endless rope haulage where tubs are traveling downhill, av detent placed in the roadway so that its lighter end projects into and its heavier end lies below the path of the tubs, said detent rocking idly while the tubs travel at the working speed but coming into action when the lighter end is struck by a runaway tub hard enough to raise the heavier end to the requisite extent, substantially as set forth.
2. In endless rope haulage, the combination, with the first axle of a runaway tub, of a device thrown by that axle into position for stopping the tub, said device rocking idly under a tub traveling at the working speed substantially as set forth.
3. In endless rope haulage, the combination with the two axles of a runaway tub, of a device brought by the first axle into position for stopping the tub by engaging with the second axle, said device rocking idly under each axle of a tub traveling at the working speed, substantially as set forth.
4:. For use in endless rope haulage, a pivoted detent placed between the rails, a. head on the detent lying in the path of the axles of the tub, and a hook on that detent normally inactive, said detent rocking idly under each axle of a tub traveling at the working speed but turning over center when struck by a runaway tub, substantially as set forth.
5. For stopping runaway tubs in endless rope haulage, the combination, with a tub, of a detent, a head on the detent, a hook on that detent, a bracket in which said detent is pivoted, and supports on the bracket for the aforesaid detent while in the active position, such detent rocking idly under each axle of a tub traveling at the working speed, substantially as set forth With reference to the accompanying drawings. 1 In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
