ROD-COUPLING.

SPECIFICATION forming part of Letters Patent No. 534,507, dated February 19, 1 895;

' Application filed November 8,1894- Serial Not 528,232. (No model.)

To all whom it may concern; i

- Be it known that I, ELLERY lvLHoAGLAND, a citizen of the United States, residing at Salinas, Montercy county, State of California, have invented an Improvement in Rod-Couplings; and Ihereby declare the following to be a f nll; clear,and exact description of. the same.

. r My invention relates to that class of couplings for joining the rods of well boring apparatus especially, though applicable to connecting other'rods such as the rods of windmills anddeep well pumps.

' My invention consists in the novel construcftion and arrangement of the coupling which I shall herein fully describe and specifically claim. i

The object of my invention is to provide a coupling for rods, which can be quickly made and broken, and while coupled-will remain absolutely secure, thereby especially" adapting the device for the joining of all rods, and

particularly the rods used in well boring. In

. accurate and positive one, precluding all dan-' the last named work, it is required that the tool below he often withdrawn to discharge and to clear it. This, after it has gone down a. considerable depth, is a matter of time, as it is necessary to'uncouple the sections of the rod as the device is hauled up, and as it is put downagain to couple the sections together once more. Itis, therefore, of the'greatest importance that the coupling and uncoupling be done with great facility and rapidity; but

at the same time the coupling should be an ger of becoming accidentally uncoupled, and one which will permit both the churning action and the "rotary movement without lost I slightest.

coupling, the lower part being shown in vertical section,

' end of one sectionA of the rod. "It is also motion or without yielding or giving in the All these results are attained by my cpupling which-I shall now describe in connection with the accompanying drawings to which reference is hereby made.

Figure 1 is a vertical section of the coupling completed. Fig. 2 is a perspective view of the two'parts 'of the couplinm. Fig. 3 is a view showingjhe two parts in 'the act of and the. other in elevation.

' The male coupling consists ofa piece having a'shank or stein'a by which it is connected, as by means of welding oroth erwise,-with the formed ,with a body 0/ having a thickness less than'th'at of the stem or shank, but of approximately the same portion, in one side or edge thereof, is made 'the notch a its standing wall being on a slight curve, while its base is slightly inclined, though this cu'rveand incline are not absolutely essential as they may be both straight surfaces,but I prefer them'as "here shown. -The female coupling is formed with a stemor or otherwise, in the end of another section B of rod, as in the opposite end of the first section.

This coupling body. portion 6', the end and sides of the cavity being'open. One side of the body, near its end, is provided with a directing wall b while the other side, and at apoint a-little lower down, is provided with a stop wall I), the inner surface of which is beveled or inclined either on a curve or in a straight plane as may be desired.

The .two sections of the coupling are fitted together by turning the male coupling at such that it will passbetween the lower end of the directing wall b ,and the inclined inner surface of the stop wall D of the female coupling. After it has passed down in this space until the base of thenotch a? in the male coupling has passed the lower end of the stop wall of the female coupling, the former coupling is then turned into line with the latter coupling,'in which position the bodies of the two couplings will be flush with each other ou each side, and the base of the stem of one will rest on the end of the body of the other, the

of the cavity of the other, will fully engage the stop wall I) and thus the coupling is complete.

'lo uncouple, the male coupling must be turned to the same angle at which it entered, and it may then be withdrawn. It will be seen that this operation can be ajvery rapid one, and in the particular use which I have mentioned, namely, that of connecting the rods of well boring apparatus, it is evident to nearly the mouth of the casing, the coupwidth.- In this'body shank b by which it is secured, as by welding I is provided with a hollowed end of the body of'one will rest in the base while the notch a that in coupling together one'section of --od.. with a preceding one which has been lowered I Patent, is-

,is permanent, as the two will then descend into the small area or diameter of the casing in which it is impossible for the male coupling to turn to the angle for withdrawal, and, therefore, as long as the rods remain in the casing, the couplings cannot come apart;

The various stops'and limitations of the two parts of the coupling are such that all the necessaryrotary motion maybe given to the rods, andalso-the churningactionwit-hout in the least disturbing the coupling connection. Nor is thereany lost motion and the parts easily draw to place.

Having thus described my invention, what lclaim asnew, and desire to secure by Letters 1. A rod coupling consisting of a section having ashank reduced in thickness and pro- ,vided with a notch in one of its edges, a second section having a hollowed or recessed body portion open at both sides with adirecting Wall b closing a portion of'the opening at one side, and a stop wallclosing a portion of the opening at the opposite side, and disposed in a'plane below that of the directing wall, said stop wall adapted to engage the notched portion of the first named section.

2. A rod coupling consisting of a, section having a shank reduced in thickness with a notch formedin one'edge, a second section receased in the direction of its lengthwith the recess opening through the top and two opposite'sides of the section, a directing wall at the upper portion of oneside of the second section and a stop 'wallat the opposite side of the section below the plane of the directing wall, having a beveled or inclined inner surface adapted to engage the notch in the edge 40 of the first named section.

In witness whereof I'have hand. v
