ROD JOINT OR COUPLING.
SPECIFICATION forming part of Letters Patent No. 477,593, dated June 21, 1892.
Application filed March 11, 1892. Serial No. 424,528. (No model.)
scription.
The invention consistsof certain parts and details and combinations of the same, as will be hereinafter described, and then pointed out in the claims.
Reference is to be had to the accompanyingdrawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a sectional side elevation of the improvement. Fig. 2 is a front elevation of the same. Fig. 3 is a sectional plan View of the same on the line 3 3 of Fig. 1. Fig. 4 is a similar view of the same on the line i 4. of Fig. 1. Fig. 5 is a like view of the same 011 the line 5 5 of Fig. 1. Fig. 6 is a perspective view of the key, and Fig. 7 is a perspective View of one of the liners.
The drill-rods A and 13 are provided with the usual heads A andB, of which the former has the threaded end A screwing into a corresponding recess 13 in the head B. On the head B is formed avertically-extending dovetail B into which fits the correspondinglyshaped key C, having a projecting end 0, adapted to pass into a recess A formed in the head A of the drill-rod A. The two recesses B and A register with each other when the heads are screwed up, as plainly illustrated in Figs. 1 and 2, the recess A however, being somewhat larger than the dovetail B so that liners D, preferably of L-shape in cross-section, can be inserted in the said recess on either side of the projecting end 0 of the key 0. i In case the joint formed by the two heads A and B wears, then the recess A still registers with the dovetail B but then some of the liners are removed from one side of the projecting end Cof the keyC and placed on the other side to compensate for the Wear of the joint. The outer surface of the key 0 is preferably segmental to corre spond with the surface of the heads A and B, so that the key presents no projection whatever, and consequently does not obstruct the up-and-down movement of the drill-rod in the well.
In order to lock the key 0 in place, the head E of a bolt E fits in the upper end of the recess B so that the lower edge of the head engages the upper end of the key 0. The bolt E passes transversely through the head B of the drill-rod B, and its nut E fits into a recess 13 formed in the said head B", so that the bolt presents no projection whatever in the well-hole. The head E is rounded off at its outer surface, so as to correspond with the rounded surface of the head B. In order to prevent the nut E from accidentally unscrewing on the bolt E, a pin E passes. through the said nut and through the bolt to lock the two together. In order to convcn iently remove the key 0 from its recess after the bolt E is withdrawn, the said key is provided with an aperture 0 for insertion of a tool to push the key out of its recess.
It will be seen that this device is very simple and durable in construction, can be very cheaply manufactured, and readily applied or removed in case it is desired to unscrew the two drill-rods A and B. In order to uncouple the rods, the operator first unlocks the nut E and unscrews the nut from the bolt, then withdraws the latter from the head. B, then slides the key 0 upward out of engagement with the recess A to permitot' unscrewing the head A from the head B.
It is understood that the device can be used not only on drill-joints, but also on joints of other machines or parts.
Having thus fully described my invention,
I claim as new and desire to secure by Letters Patent 1. A rod joint or coupling comprising the rods having a screw-threaded connection and aligning longitudinal dovetail keyways on their outer faces at their abutting ends, a key slid into the said ways, and a bolt the head of which closes the entrance end of the keyway.
2. The combination, with the rods A B, having their abutting threaded ends enlarged or headed, as at A B, of a dovetail keyway formed longitudinally in the outer faces of the [00' heads and open at one end to admit the key and closed at its opposite end, a key slid into said Way and crossing the joint, a transverse bolt the head of which closes the open end of the keyway, and a nut on the opposite end of the bolt and lying Within a recess in the rodhead, substantially as set forth.
3. A rod joint or coupling comprising a key fitted to slide in one of the members of the joint and engaginga recess in the other member, a bolt held in one of the members of the joint and extending with its head into the guideway of the said key, so as to lock the latter in place, and sets of liners held in the recess of the second member and engaging the projecting end of the said key, substantially as shown and described.
4. In a rod joint or coupling, the combination, with the two members of the joint screwed together and formed with registering recesses on their outer surface, a key fitted to slide in one of the said recesses and engaging with its projecting end the recess in the other member, liners held in the recess of the second member and engaging the sides of the said key, and a bolt held in the firstnamed member and formed with a head arranged in the path of the said key to lock the latter in place, substantially as shown and described.
