CHARLES STEINER, OF BRISTOW, OKLAHOMA.

ROD COUPLING.

Application filed February 3, 1923.

To all whom it may concern.-

Be it known that 1, CHARLES STEINER, a citizen of the United States, residin at Bristow, in the county of Greek and tate of Oklahoma, have invented a new and useful Rod Coupling, of which the following is a specification.

This invention aims to provide a simple means whereb rods of the sort used in well pumps may be connected and disconnected readily and rapidly.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in theprecise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in side elevation, a device constructed in accordance with the invention; Figure 2 is an elevation wherein the device is viewed at right angles to the showing of Figure 1; Figure 3 is a cross section on the line 3-3 of Figure 1.

The numeral 1 marks a lower rod whereunto an enlarged head2is secured, in any desired way, the head having a thinned longitudinal fin 3, and there being inclined shoulders 4 at the upper end of the head 2, the shoulders being located on opposite sides of the fin 3. A superficial slot 5 extends longitudinally of the head 2 and is prolonged into the lower portion of the fin 3. A transverse notch 6 is fashioned in the outer edge of the fin 3, the notch being prolonged longitudinall of the fin 3 to form a bearing opening 7 The lower end of a loop-shaped link 8 is pivotally mounted in the opening The numeral 9 designates an L-shaped retainer including a shank 10 and a transverse extension 11. The extension 11 is shaped as at 12 to correspond with the outline of the bearing opening 7. The shank 10 of the retainer 9 is received in the slot 5, and the extension 11 of the retainer projects into the notch 6 to hold thelower end of the link 8 in the opening 7 for swinging movement.

Serial No. 616,752.

The shank 10 of the retainer 9 is connected to the lower end of the fin 3 and to the head 2 by a securing element 14: such as a screw. t its upper end, the fin 3 is stepped to form transversely spaced longitudinal abutments 15.

The numeral 16 designates an upper rod whercunto an enlarged head 17 is secured in any desired way. The head 17 has a thinned longitudinal fin 18 which at its lower end, is stepped to form transversely spaced vertical abutments 19. There are inclined shoulders 20 at the lower end of the head 17, on opposite sides of the fin 18. An opening 21 is formed in the edge of the fin 18, the opening 21 being extended longitudinally of the fin 18 to form a seat 22 and to provide a projeotion 23 outwardly of the seat. Suppose that the rods 1 and 16 are to be coupled together. Then, the rod 1 is supported by an elevator (not shown), the elevator being engaged with the lower end of the head 2. The link 8 is swung in the direction of the arrow A in Figure 1 until it rests on the shoulders 4:. The rod 16 is lowered, the head 17 being disposed to the left of the head 2 in Figure 1. The upper end of the link 8 is engaged in the seat 22 which is formed in the fin 18 of the head 17. When an upward pull is exerted on the rod 16, the rod 16 and the head 17 will move transversely, in the direction of the arrow B in Figure 1, until the vertical shoulders 19 on the fin 18 of the head 17 engage with the corresponding shoulders or abutments 15 on the fin 3 of the head 2 as shown in Figure 1. B a reversal of the operation above described, the rods 1 and 16 may be uncoupled. It is obvious that an uncoupling and cou pling of the sort above mentioned can be carried out much more readily than can the corresponding operations, when the rods are threaded together, as is the prevailing practice. Should it be necessary to thrust the rod 1 forcibly in a downward direction, by pressure exerted from the rod 16, this operation can be done and the rods 1 and 16 will not be separated.

What is claimed is 1. In a device of the class described, upper and lower coupling members, and a link pivotally mounted on the lower member, the lower member having a transverse shoulder upon which the link rests when said memhere are separated, the upper member being provided in one edge with an opening for the reception of the link and said members being supplied with cooperating longitudinal abutments.

2. In a device of the class described, upper and lower coupling members, each including a head and a thinned fin, and a link pivotally mounted in the fin of the lower member and extended about the fin of the lower member, the head of the lower member constituting a shoulder on which the link is adapted to rest when said members are separated, the fin of the upper member being provided in one edge with an opening for the reception of the link, and the fins of the upper and lower members being supplied at their meeting ends with meeting longitudinal abutnients.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.

CHARLES STEINER.
