SPECIFICATION forming part of Letters Patent No. 639,494, dated December 1% 1899. Application filed September 16, 1899. Serial No. 730,762. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK A. BAGLEY,a citizen of the United'States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Windmill and Pump Couplings; and I do hereby 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. I

The object of this invention is to produce a simple and easily operated device for connecting and disconnecting the connecting-rod of a windmill or analogous machine with a pump-rod or the like.

The nature of the invention is fully disclosed in the description and claims following, reference being had to the accompanying drawings, in which-- Figure 1 isa front view of a device embodying my invention. Fig. 2 is a side view .of the same, Sheet 2. Fig. 3 is a central section of the same Fig. 4 is a detached view of one of the pawls and a portion of the connecting hand-lever.

Similar letters of reference indicate corresponding parts.

In the drawings, A designates the rod connecting with the crank of a windmill or analogous machine. (Not shown.) portion of a puinp-rod. The usual practice is to connect these parts by a casting fastened to the connecting-rod and provided with a hole to register with a similar hole in the pump-rod, through which passes a suitable bolt. The construction is such thatit is practically impossible to connect the parts while the windmill is in motion, and to do so when the windmill is at rest usually requires the forcible raising of the pump-rod, which naturally descends when released from the windmill. The operation is thus one of some difficulty and requires considerable time. My device enables even a child to connect or disconnect the windmill in a moment, and whether in motion or at rest.

Referring now to the drawings, 0 is a casting provided with a recess at the upper end to take the lower end of the connecting-rod. A, to which it is fastened by suitable bolts D.

B is the upper This casting is hollow, as indicated in Fig. 3, and forms a guide for a slide E, to the lower end of which is secured the pump-rod by a bolt F. The casting O is provided with lat eral extensions C at the lower end, and to one of these is hinged a hand-lever G. To

the lever, above the hinge, is pivoted a pawl II, adapted to engage notches E at the side of the slide E. In practice, for the sake of greater strength and security, another pawl 11 is pivoted to a link G hinged to the opposite extension of the casting, and engages similar notches on the opposite side of the slide. v This pawl connects with a downward extension G of the lever by a link I, so that an outward throw of the lever disengages both pawls. In Fig. 2 it will be seen that the lower portion of the lever-is bifurcated, the parts connecting by a bridge G so as to embrace both the pawl II and the lug C The bridge serves also as a stop for the pawl which has a shoulder H as shown in Fig. 4., whereby it may be disengaged from the notches in the slide.

The point of engagement of the pawl H with the slide when in operative position is a little outside a line drawn through the center of the hinge and the pivot of the pawl, and thus the lever when thrown to the position shown in Fig. l-is automatically locked in position. A lug C limits theinward movement of the lever. The slide is preferably provided with lat eral extensions E fitted with set-screws E by means of which any lost motion may be taken up, and the downward movement of the housing 0 with respect to the slide may be accurately adjusted so as to coincide with the engagement of the pawls.

It is to be understood that the guide or housing O and the slide E are long enough to remain in engagement even with the connecting-rod A at its highest point and the pumprod at its lowest-that is to say, with the pawls disengaged the slide still enters the housing, which is free to slide up and down on it. To connect the parts operatively, it is but necessary to throw the lever to the position shown in Fig. 1. The first downstroke of the connecting-rod does not bring the housing clear to the limit of movement on the slide, but the pump-rod is lifted the greater part of its normal stroke, and as the connecting-rod descends faster than the pump-rod naturally falls the parts reach their final operative position in the course of a few strokes. Itis to be noted, further, that by a quick backand-forth movement of the lever, taking advantage of the slow descent of the pump-rod, the latter may be jacked up to the limit of its movement in the housing.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. A connection for a Windmill connectingrod and a pump-rod, comprisinga guide or housing attached to the lowerend of the connecting-rod, a slide adapted to move freely therein, and secured to the upper end of the pump-rod, said slide being serrated for the engagement of a pawl, a lever hinged to the housing, and a pawl adapted to engage said slide, and to be thrown in and out of engagement by said lever.

2. A coupling for windmill connecting-rods and pump-rods, comprising a notched slide adapted to connect with the pump-rod, a housing to receive the same loosely, and to connect at the upper end with the connectingrod, a lever hinged to a lateral extension of the housing, and a pawl pivoted to said lever, and adapted to engage the notches on said slide, substantially as and for the purpose set forth.

3. Awindmill and pump-rod coupling, comprising a notched slide adapted to connect securely with the pump-rod, a guide or housing therefor, secured at the upper end to the connecting-rod, and having lateral extensions at or near the lower end, a lever hinged to one of said extensions, a pawl pivoted to said lever, another pawl pivoted to the other extension, both pawls being adapted to engage the notches of the slide, and a link connecting the lever with the opposite pawl, substantially as and for the purpose set forth.

4. A windmill and pu nip-rod coupling, comprising a serrated slide secured to the pumprod, and having lateral extensions provided with adjusting-screws, a guide or housing therefor secured to the connecting-rod, and having extensions coinciding With said adjusting-screws, a lever hinged to one of said extensions, and a pawl connected with said lever, and adapted to be thrown in or out of engagement with the slide thereby, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
