Description

J OHN' EMERY LESTER, OF OMAHA, NEBRASKA.
PUMP-ROD COUPLING.
Specification of Letters Patent.
Patented Dec. 19, 1905.
Application filed. January 23. 1905. Serial No. 242,322.
1'0 all whom it may concern Be it known that I, JOHN EMERY LESTER, a citizen of the United States, and resident of Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Pump-Rod Couplers, of which the following is a specification.
My invention relates to pump-rod couplers of the type adapted to operatively connect a pump-rod with the rod of a windmill for actuating the pump; and it is the object thereof to provide a simple and durable coupler of this class.
In the accompanying drawings, Figure 1 is a front view of the upper portion of a pumprod and the lower portion of a windmill-rod having my coupler applied thereto. Fig. 2 is a side view of the same. Fig.3 is a sectional plan view of the mill-rod channel-bar, showing the coupling-pin in engaged position. Fig. 4 is a similar View showing the coupling-pin in disengaged position. Fig. 5 is a rear side View of the coupler. Fig. 6 is a side view of the coupler applied as an attachment to the ordinary form of channel-bar, and Fig. 7 is a plan view of the same.
In the drawings, 1 represents the upper part of a pump-rod, the same being usually of rectangular section, having the holes 2 therein and passing through the guide or extension of the pump-body 3.
The mill-rod 4 has the channel-bar 5 secured thereto in the usual manner. The said channel-bar is of ordinary form, except at the foot thereof, where the U-shaped loop or bracket 6 extends out from the rear side of the same, as shown. Through the rear side of said bracket passes the pin 7, having the handle 8 and enlarged portion 9 thereon, the pin being adapted to pass also through the rear and front sides of the channel-bar and through the holes 2 in the pump-rod 1. Passing around the enlarged portion of the pin is a helical or screw-like groove 10, of which the lead or pitch is equalto the combined thickness of the pump-rod and the front side of the channel-bar. A small screw 11 is placed in the bracket, so that the end thereof extends into the groove 10, as shown in Figs. 2 and 5. The said screw 11 prevents the removal of the pin from the bracket and forms an element mating with the helical groove, so that when the pin is turned or rotated by means of the handle, as indicated by the dotted circle in Fig. 5, the pin will be inserted in or withdrawn from engagement with the pump-rod,
accordingly as the handle is turned to the right or left. The ends of the helical groove are preferably at the side of the pin opposite the handle 8, so that when the pin is turned to either limit of its movement the handle will hang down from the bracket and tend by its weight to retain the pin in such position.
In Figs. 6 and 7 the coupler is shown applied as an attachment to the ordinary form of-channel-bar, in this case the bracket 6 being clamped over the sides of the channel-bar by means of the bolt 12 instead of being formed integral with the channelbar, as shown in Figs. 1 to 5.
Now, having described my invention, what 1 claim, and desire to secure by Letters Patent, is
1. In a coupler of the class described and in combination with the pump-rod and channelbar, a bracket carried by the channel-bar, a pin passing through said bracket and adapted to pass through the channel-bar and pumprod to operatively connect the same, means preventing the removal of the pin from the bracket, there being in the pin a helical element of which the pitch is greater than the thickness of the pump-rod, mating means on the bracket engaging said helical element in the pin whereby rotation of the pin will cause,
longitudinal movement thereof to engage the same with the pump-rod or disengage the same therefrom, and means tending to retain the pin either in engaged or disengaged position.
2. In a coupler of the class described and in combination with the pump-rod and channel-bar, a bracket carried by the channel-bar, a pin passing through the said bracket and adapted topass through the channel-bar and pump-rod to operatively connect the same, there being in the pin a helical groove of which the ends are closed, a mating element on the bracket entering said groove by which rotation of the pin will cause longitudinal movement of the same, said mating element by engaging the closed ends of the groove preventing removal of the pin from the bracket, and means tending to retain the pin in position when turned to either limit of its movement.
In testimony whereof I hereunto aflix my signature in the presence of two witnesses.-
J. EMERY LESTER.
