HOMER A. TUNIS, 0F RINGWOOD, OKLAHOMA.

COUPLING.

Application led December 12, 1908.

To all whom 'it may concern:

Be it known that I, HoMnR A. TUNIS, a citizen of the United States, residing at Ringwood, in the county of Major and State of Oklahoma, have invented a new and useful Coupling, of which the following is a specification.

The objects of the invention are, the provision in a merchantable form, of the device of the above mentioned class, which shall be inexpensive to manufacture, facile in operation, and devoid of complicating` parts; the provision of novel means for locking and operating the retaining bolt;fother and further objects being made manifest hereinafter, as the description of the invention progresses.

The invention consists in the novel construction and arrangement of parts hereinafter described, delineated in the accompanying drawings, and particularly pointed out in that portion of this instrument wherein patentable novelty is claimed for certain distinctive and peculiar features of the device, it being understood that within the scope of what hereinafter thus is claimed divers changes in the form, proportions, sizes, and minor details of the structure may be made, without departing from the spirit or sacrificing any of the advantages of the invention.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawing. A

In the accompanying drawing, Figure 1 shows my invention in perspective; Fig. 2 is a vertical longitudinal section thereof; Fig. 3 is a transverse section on the line A B.

To enable others skilled in the art to which my invention appertains, to make and use the same, I will now describe my invention and explain its operation.

The invention comprises a housing 1, which may be of any form; preferably however, as shown, it comprises a base member 2 and side walls 3 outstanding from the face 4 of the housing. The lower end of the housing 1 is provided with a central guideway 5, arranged to receive the piston rod of a pump. A resilient tongue 6 is provided, the said tongue being rigidly attached at one of its ends to the housing 1 by means of the block 7. The lower end of the housing Specification of Letters Patent.

Patented Dec. 14, 1999.

Serial No. 467,260.

1 is provided with yoppositely disposed, transversely alined

openings

8 and 9, in which is slidably mounted the retaining bolt 10, arranged to cross the guide-way 5 and to be terminably supported on opposite sides of the guide-way 5, as shown. One end of the retaining bolt 10 is bifurcated to form standards 11, carrying a transversely disposed bolt 12 about which is bent the free end of the resilient tongue 6 to forni a pivotal connection between the tongue 6 and the retaining bolt 10.

A lever 13 is pivotally mounted in the housing 1 between the side walls 3, and provided with a central opening 14 arranged to receive the tongue 6. The lower end of the lever 13 carries a transversely disposed shoulder 15 arranged to engage the lower face of the tongue 6 in lifting relation, as shown in dotted line in Fig. 2. This shoulder 15 is so positioned upon the lever 13, relative to the pivotal connection 21 upon which` the lever is mounted, that, when the lever 13 is thrown downward, as shown in dotted line in Fig. 2, the retaining bolt 10 will be withdrawn from the opening 9 and from the guide-way 5, butnot from the opening 8, the retaining bolt 10 thus being left in a position operative to be shot forward into the opening 9 again, as hereinafter described.

A shoulder 16, integral with the housing 1, is transversely disposed between the side walls 3 to receive the thrust of the pitman of the windmill. Between the outstanding side .walls 3, and abutting against the shoulder 16 is rigidly mounted the block 7 which if desired, may be fashioned integral with the housing 1. vThe block 7 is provided with a seat 17 disposed parallel to the face 4 of the housing and arranged to receive the iiXed terminal of the tongue 6. Lateral members 18 rise from the seat 17 and are disposed between the said seat 17 and the side walls 3 of the housing 1. These lateral members 18 serve to retain the tongue 6 from contact with the side walls 3 of the housing. The seat 17 lies in a plane outwardly removed from the plane of the face 4 of the housing, and, as shown in Fig. 2, the tongue 6 rests normally at some distance from the face 4. By this construction it is possible to bend manually the tongue 6 toward the face 4, to increase the resiliency of the said tongue, to adjust the speed with which the retaining bolt 10 moves, and to secure a quicker lock; should these adjustments become necessary.

Referring now to Fig. 3, it will be seen that the inner faces 19 of the walls 3 are made to Hare laterally, and that, as shown in Figs. 1 and 3, the lever 13 is provided with laterally flaring, resilient 4wings 20, positioned to engage the faces 19 when the lever 13 is in the position shown in solid line in Fig'. 2, whereby the said lever 13 may be locked between the faces 19. The movable end of the lever 13, being inclosed between the wings 20, is confined against lateral movement, and the possibility of the retaining bolt 10 becoming jammed in the opening 8, kwhen the said bolt 10 is moved from the position shown in Fig. 1, is thus reduced.

The operation of the device is as follows:

My coupling is attached to the pitman of a windmill, as shown in dotted line in Fig. 2, the said pitman abutting against the shoulder 1G as shown. The piston rod of the pump is arranged to reciprocate in the guide-way 5, the parts of my invention being in the positions shown in Fig. 1, and in dotted line in Fig. 2.

Then it is desired to eii'ect a coupling the lever 13 is moved to a position intermediate the dottedand solid line positions of Fig. 2, whereby the retaining' bolt 10 willV be made to bear against the piston rod (not shown) of the pump, and there be held by the resilient tongue 6. As my coupling reciprocates with the pitinan of the windmill, the end of the retaining bolt 10 will traverse longitudinally, the upper terminal of the piston rod of the pump, until it, the said bolt 10, encounters one of the transversely disposed openings commonly provided in the upper terminal of the piston rods of pumps designed for use with windmills. Impelled by the tongue 6, the bolt 10 will enter one of these openings in the piston rod of the pump, and move into the position shown in solid line in Fig. 2, and designated by the numeral 10.

From the intermediate position hereinbefore mentioned, the lever 13 is moved to the position shown in solid line in Fig. 2, in which position it will be retained by the peculiar relation between the wings 2O and the faces 19 as hereinbefore described, and particularly delineated in Fig. 3.

When it is desired to disconnect the pump @4eme from the windmill by which it is operated, the lever 13 is moved from the position shown in solid line in Fig. 2 to the one shown in dotted line therein. During this operation, the shoulder 15 will have engaged the under face of the tongue 6, raising said tongue, and withdrawing the bolt 10 from the opening 9 and from the guide-way 5, the terminal of 'the bolt 10 resting in the opening S, as shown in dotted line in Fig. 2, whereupon the connection between the pitman of the windmill and the piston rod of the pump will be broken.

Having thus described my invention, what l claim as new and desire to protect by Letters-Patent, is:

l. ln a device of the class described, a housing having outstanding side walls provided with beveled inner faces; a tongue disposed between the walls; a locking bolt carried by the tongue; a lever pivoted between the walls and being arranged to lift the tongue, the lever being provided with resilient flaring wings to engage the beveled faces of the walls.

2. ln device of the class described, a housing having outstanding side walls provided with beveled inner faces; a tongue disposed between the walls; a locking bolt carried by the tongue; a lever pivoted between the walls and arranged to lift the tongue, the lever being provided with resilient wings to engage the beveled faces of the walls.

3. 1n a device of the class described, a housing having outstanding side walls; a tongue disposed between the walls; a locking bolt carried by the tongue; a lever pivoted between the walls and arranged to lift the tongue, the lever being provided with resilient Haring wings to engage the walls.

4l. n a device of the class described a housing having outstanding side walls; a tongue disposed between the walls; a locking bolt carried by the tongue; a lever pivoted between the walls and arranged to lift the tongue, the leverI being arranged to be wedged between the walls.

ln testimony that I claim the foregoing as my own, I have hereto aliixed my signature in the presence of two witnesses.
