LOCKING-HOOK FOR MINERS BUCKETS.

SPECIFICATION forming part of Letters Patent No. 643,534, dated February 13, 1900.

Application filed August 1 8, 1 89 9 To all whom it may concern:

Be it known that I, EDWARD J. RICHMOND, a citizen of the United States, residing at Carthage, in the county of Jasper and State of Missouri, have invented certain new and useful Improvements in Automatic Locking- Hooks for Miners Buckets; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in self-locking hooks for miners buckets; and the object is to provide a simple and effective safety device of this character.

To this end the invention consists in the construction, combination, and arrangement of the several parts of the device, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a perspective view of my improved self-locking safety-hook. Fig. 2 is a longitudinal section with the locking-tongue raised. Fig. 3 is a similar view with the tongue closed and the'bucket-bail shown in dotted lines. Fig. 4 shows a simple manner of connecting the socket with a bucket-bail. Fig. 5 is a modified form of hook. Fig. 6 shows the manner of attaching the rope direct to the hook without the intervention of the swivel. Fig. 7 shows another form of cross head provided with a ball bearing sleeve. Fig. 8 is a vertical section of the same. Fig. 9 is a detail view of the sleeve or spool. Fig. 10 is a detail view of the crosshead cast in one piece.

1 denotes a cross-head or socket consisting of two counterpart yokes 1 1, the meeting faces of which form a recess to receive the swivel-eyebolt 2.

3 and 4 represent the diverging arms, which encompass and are permanently fixed to the yokes 1 1 by the transverse rivets 2' 2.

5 denotes the latch'pivoted on the rivet 5 in the lower end of the arm 3, the tongue 6 of the latch passing through the lower end of the arm 4 and resting on the bar 10. As

shown in Fig. 3, the face of this tongue 6 is Serial No. 727,726. (No model.)

curved at 8 to engage the correspondinglycurved meeting face 9 of the bar 10, so that when the weight of the bucket is on the latch any tendency of the arms to separate is obviated.

, 12 denotes a thumb-plate formed integral with the latch 5 and in addition to serving as a guard to limit the upward movement of the tongue by its coming in contact with the end of the arm 4 also acts as a guard to facilitate the entrance of the bucket-bail into the socket, and by acting as a counterbalance to restore said tongue to its locking position it also serves as a convenient medium for expeditiously manipulating said tongue.

13 denotes the bucket-bail, (shown in dotted lines in Fig. 3, and to release said bail the socket is pressed down and the tongue is raised to the position shown in Fig. 2, which is very simply and conveniently accomplished by means of the thumb-plate. The socket is then clear of the bail and the tongue allowed to drop to its normal position.

A very simple and expeditious manner of connecting the device with a bucket-bail will be understood by reference to Fig. 4, the hook or socket being swung in the direction of the arrow until the thumb-plate meets the ball, at which point the hook' is depressed 'until the tongue contacts with the bail, rising past it, and then falling back by gravity under it to secure the bail in place.

Referring now to Fig. 5, the cross-head is made in two pieces, as before; but the eye 2 in the swivel-bolt 2 is formed horizontal, so that the end of the rope may be passed through it and knotted to secure it in'place.

In Fig. 6 the eyebolt is dispensed with entirely and the end of the rope passed through the cross-head and knotted, as shown.

In Figs. 7 and S I have dispensed with the eyebolt and in lieu thereof substituted a sleeve 14, the upper end of which is formed with a guard-collar 15 and the lower end with a heavier bearing-flange 16, the upper face of which is formed with a ball-race 17, in which are mounted the bearing-balls 18. In this instance the end of the wire cable 19 is leaded in the usual manner in the sleeve to secure it in place.

In Fig. 10 I have shown the cross-head made in one piece and the orifice much enlarged to receive a heavy hemp or manila rope, which is passed through and knotted in the usual manner to retain it in place.

It will of course be understood that various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this in- Vention.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, 1s

1. In a safety bail-hook, a swiveled socket formed with diverging arms, a latch fulcrumed in one arm and having its free end
