AUTOMATIC CATCH FOR MINING-BUCKETS, 850.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed October 1, 1908 Serial No. 455,755

To all whom it may concern:

Be it known that I, THOMAS C. WRIGHT, citizen of the United States, residing at Goldfield, in the county of Esmeralda and State of Nevada, have invented new and useful Improvements in Automatic Catches for Mining-Buckets and the Like, of which the following is a specification.

My invention relates to an attachment for mining shafts and the like, for holding a bucket or cage at any desired point in or above the shaft or well.

The particular object of the invention is to provide an automatic catch by which the cross-head carr 'ng the bucket or cage may be engaged an hung up whenever it is desired temporarily to discontinue the use of a bucke'tjor cage, or to land the bucket at the side} or change buckets, or where it is desired tdinspect the hoisting rope, or to use the rope or cable for other purposes.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which igure 1 is a front elevation of the device. Fig. 2 is a partial section showing the stop in readiness to receive thecross-head; Fig. 3 is a partial section with stop and trigger in closed position. Fig. 4 is an edge view. Fig. 5 is a detail of the Weight.

While I have shown the invention applied especially in conjunction with a mining shaft and hoist, it is manifest that it can be used in other places, and under other conditions, as in an elevator Well in high buildings and thelike.

A represents a cross-head sliding on the iides '2 and su porting, for instance, a-

ucket or cage; t e cross-head and bucket being operated by any suitable means, a

the rope or cable 4.

' The invention resides in ap l 'ng at any desired point in one or both of til e guides 2, the following stop mechanism engageable and' disengageable by the cross-head: the catch comprises essentiall a pivoted stop og or trip 6, wit

weight 7 or its suitable means, as a sh lng 6 normally equivalent, to carry the tri outward into the path of t e cross-hea I prefer to mount the stop or catch 5, the trip 6 and weight 7 in a channel frame 8 which may be made of metal or any other suitable material and adapted to be inserted in a suitable kerf in one or the other, or both,

of the guides 2. Both the stop 5 and tri 6 are weighted or counterbalanced so that they project normally into the path of the cross-head. The sto or catch 5'may be-of any suitable size, siape or material. As here shown, it is made triangular and pivoted at its lowerend, as at 9, so that its weight normally tends to throw it outward into the path of the cross-head. The outward movement of the stop is limited by suitable means, as the rigid brace or bracket 10.

The trip 6 is so positioned that it may swing upward without interfering with, or acting upon, the catch 5, but when pushed downward it will engage aprojcction 11 on the stop 5 and carry the stop back within its housing 8, leavin the cross-head free to move down. If 51 metal, its back would be closed in, and the weight 7 retained in place by suitable means, as a cover plate 12 by which the device may be attached to a guide 2.

While the weight 7 may be of any desired form, I have here shown it as comprising a loose member or bar slidingin suitable guides 13, with the downward movement of the weight limited by stops 14 so as to allow the member 6 to move upward freely. The member 6 is pivoted at its rear end at 15, and

e housing 8 is made of it is maintained normally in horizontal posiand if the rope is then slackened the crosshead will be supported on the stop or catch.

or sup- 6 This stop will then serve to hang u port the cross-head and bucket unti it is desired to use the same again. The only way to lower the bucket after the cross-head has been engaged by the stop is to hoist up on the cross-head until the trip 6 is allowed to drop and hang free below and in the path of the.

cross-head. Then by lowering the crosshead the trip 6 is pushed down, and the weight 7 is correspondingly lifted; the trip- 6 encountering in its downward movementthe projection or trigger 11, whichlatter is without interference.

' served that while the catch 5 is limited by the obstruction 10 in its downward move: ment, the trip 6 is free to turnup or down; and in the downward movement of the trip the catch is moved upward and out of the way of the cross-head.

' Having thus described my invention, what I claim and desire to secure ent is-- l. The combination with a sliding crosshead, of a stop member normally projecting into the patlrgof the cross-head, said stop member freely turflableout of the way of the cross-head when the latter moves in one 'direction, but normally presenting an obstruction to the movement of the cross-head in an opposite direction, and a pivoted tri operby Letters Patatable by the cross-head and engageab c with said catch to push the latter out of the way and allow a free movement of-the cross-head in the opposite direction. j

g 2. The combination with a sliding cross head, of a guide for the cross-head, a pivoted catch in the guide normally projected "into"- the path of thecross-head and, limiting the movement of the cross-head in one direction, and a pivoted trip engageable by the cfosshead and engaging a trigger on the catch, said catch and trip mova le out of the way of the crosshead when the latter, moves in one direction, and saidtrip engaging said trigger to remove the catch out of the way of the cross-head when the latter moves in the opposite direction.

head, of a guide for the cross-head, a catch carried by the guide and normally projecting into the ath of thecross-head, a. pivoted trip mem er. disposed in the path of the cross-head and free "to swing u." o'r down when engaged by the cross-hea the up and down movement of thelatter, meansfor limiting the downward swinging movement of said catch, and meansflwhereby on the downward movement of the trip the catch is given an upward movement to remove'the latter out ofthepath ofthe cross-head.

4. The combination with a sliding crosshead and vertical pivoted catch norma ly projecting into the path of the cr oss-head and adapted to form a stop to the movement of the cross-head in one direction, .and a pivoted trip member normally projecting into the path of the cross-head, said trip having a movement uides therefor, of a catch out of interference with the crosshead.

5. The combination with a sliding crosshead and vertical ides therefor, of a pivoted catch normall y projecting into the path-of the cross-head and adapted.- to form asto to the movement of the cross-head in bne irection, a pivoted trip member normally pro'ectingl head, sairf trip independent of the catch, and said trip engageable with the catch on the downward movement of the tri to move the catch out into the path of the cross-' aving a movement upward of interference wit .the cross-head, and

means for automatically returning said parts by the cage.

means for automatically returning 4 'dgparts into normal operative position when released by the cage.

means for automatically returning said, parts i into normal operative position when. re-.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses.
