The present invention relates to new and useful improvements in pump jacks and has for some of its objects to provide a device of this character which will be comparatively simple in construction, strong, durable, highly efficient and reliable in operation and which may be manufactured and installed at low cost.
Another important object of the invention is to provide a pump jack which includes a power take off for driving other machinery should it be so desired.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:-
Figure 1 is a view in front elevation of a pump jack constructed in accordance with the present invention.
Figure 2 is a view in side elevation thereof.
Figure 3 is a vertical sectional view, taken substantially on the line 33 of Figure 1.
Figure 4 is a detail view in front elevation of the upper end portion of the push or lift rod.
Figure 5 is a horizontal sectional view, taken substantially on the line 5-5 of Figure 1.
Figure 6 is a vertical sectional view through the guide.
Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a metallic bracket l which is secured vertically on a base 2, as at 3. J ournaled in bearings 4 on the bracket l is-a horizontal worm shaft 5 having pulleys 6 fixed on its ends. One of the pulleys 6 is for receiving power from a suitable source of supply, such as an internal combustion engine, and the other of said pulleys 6 is to permit connection with any other machinery that it is desired to drive.
The reference numeral 1 designates a worm gear wheel which is rotatably mounted on the bracket l and operatively engaged with the worm shaft 5. Rising from the upper end of the bracket I is an integral guide 8 having a slideway 9 extending vertically thereinto from its upper end. A vertical slot I in the guide 8 communicates with slideway 9 and the purpose of said slot will be presently set forth. The pump casing II, which rises from the base 2, is firmly secured to the guide 8 by clamps l2.
Mounted for vertical reciprocation in the guide 8 and rising thereabove is a lift rod l3 through the upper end portion of which a horizontal arm I 4 extends, said arm l4 being slidably mounted in an opening I which is provided therefor. At one end, the arm I4 is pivotally and detachably connected to the pump rod 5 l6, as at H.
The reference numeral l8 designates a retaining pin slidably mounted in the upper end portion of the lift rod l3 and which is engageable selectively in recesses or grooves I9 and 20 which are provided therefor in the arm M. A weight 2| is provided on the upper end of the pin l8 for assuring proper seating of said pin in the recesses l9 and 20. The weight 2| also constitutes a handle for lifting the pin I8.
The lift rod I3 is connected to the gear wheel I for actuation thereby through the medium of a pitman 22. The connection 23 between the pitman 22 and the lift rod l3 travels in the slot ll] of the guide a. This is illustrated to advantage in Figures 1 and 5 of the drawings.
It is thought that the operation of the pump jack will be readily apparent. The worm shaft 5 is driven from any suitable source of power by a belt from said source of power trained over 25 one of the pulleys 6. The lift rod I3 is, of course, actuated by the worm shaft 5 through the gear 1 and. the pitman 22. Of course, vertical movement of the lift rod I3 is transmitted to the pump rod l6 through the arm l4. Power to drive other machinery may be conveniently had by operatively connecting said other machinery with the free pulley 6. When the apparatus is utilized in this manner, the pump rod I6 is disconnected from the arm I4 and said arm 14 is shifted to inoperative or an out of the way position in the lift rod I3, in which position said arm is retained by engaging the pin H3 in the recess 20.
It is believed that the many advantages of a pump jack constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is:--
A pump jack comprising a vertical bracket, a worm shaft journaled horizontally on said bracket, pulleys ,fixed on the ends of the worm shaft,
a vertical guide rising from the upper end of the bracket, said guide having a vertical slideway extending thereinto from its upper end and further having a vertical slot therein communicating with the slideway, a lift rod operable in the slideway and rising above the guide, a shaft on said lift rod projecting through said. slot, a worm gear rotatably mounted on the bracket and operatively engaged with the worm shaft for actuation thereby, a pitman operatively connecting the shaft of the lift rod to the worm gear for actuation thereby, thes'shaft connectionflbetweensaid pitman and the liftarod traveling; in
, ring thereto.
to the pump rod, said rod having recesses therein, a weighted pin slidably mounted in the upper end portion of the lift rod and selectively en gageable by gravity in the recesses for securing the arm in operative or inoperative position, and clamps on the guide for securing the pump cas- FRANK BOLAGEK.
