Application filed April 3,
To all whom it may concern:
Be it known that I, GEORGE ALnnRsoN, a citizen of the United States, residing in the city of La Salle, county of La Salle, and State of Illinois, have invented certain new and useful Improvements in Pump Jacks, of which the following is a specification.
My invention relates to improvements in pump jacks and has for its object the proc notion of a pump jack, the construction of which is very simple and inexpensive, in which the parts are made up in such a manner and of such material so that practically no machinist labor is required on the parts. The parts are made up so that they are reversible and interchangeable, so that it can be readily assembled and will require only one pattern to be made for each two parts and does away with all keys and keyseats.
I accomplish these objects by the means shown in the accompanying drawings, in which Fig. 1 is a side view of my invention, mounted ready for operation.
Fig. 2 is a partial sectional view along a line AB of Fig. 1.
Fig. 3 is a similar partial sectional view of a modification of my pump j ack.
Similar numerals represent similar parts throughout the several views.
In the drawings, 1 represents the pump on which my jack is mounted by means of outer clamping pieces 2 and bolts 3 which pass through apertures in 2 and apertures in the frame pieces 4:. Frame pieces 4: comprise two pieces made up exactly the same so that they both can be cast from one pattern, so that by reversing one of the frame pieces and bolting it together by means of a bolt 6 and using a cylindrical tube 8 around said bolt as a spreader and projection 9 from each of said frames 4: and bolts 10 passing through. projection 9, a complete frame is made up to retain the mechanism required. Journaled on tube 8 is a belt wheel 11, which has a pinion 12 on either side which meshes with an internal gear 13, which is ournaled on a tube 7, which is clamped in frames t by means of a bolt 14. A bolt 5 passing through the tube 7 holds the cap pieces 15 on the ends of the tube 7 and retains the internal gears 13 in position. Fastened on each gear 13, by means of a bolt 16 passing through the aperture and cylindrical depression shown on gear 13 is a tube 17 which JACK.

carries the pitman 18, which is retained in position by means of the collar 19, which is also held by the bolt 16. 20 is an additional aperture for changing the stroke of my pump jack. The tubes 17 8 and 7 are preferably pieces of seamless drawn tubing, which are uniformly smooth and do not require any machine work on the surfaces and the parts of the pinions and internal gears by means of which they are journaled on said tubes as well as all other apertures are cast with suitable smooth cores so that no machine work of any kind is required on the parts of my invention.
In the modification of my invention shown in Fig. 3, an additional reduction gear 21 is shown in position, so as to give a still more powerful pump jack by using the same kind of construction.
From the above description it will be seen that my construction requires a minimum of patterns and no machine work at any point and the construction is so simple that it can be readily assembled by one having very little mechanical skill and at the same time is very inexpensive and a very substantial mechanism.
It will be understood, of course, that while l. have here shown one form of my invention, I do not wish to limit myself to the exact form shown, but desire to have it taken in a sense illustrative of any and all the forms that come fairly within the scope of the appended claims.
I claim 1. In a pump ack, two similarly formed frames, a plurality of cylindrical members clamped between said frames with means for fastening said cylindrical member and said frames together, a pinion and an internal gear journaled on said cylindrical members and means on said internal gear and said frames which co-act with a pump to operate same.
2. In a pump jack, two similarly formed frames, a plurality'of cylindrical members clamped between said frames, with means for fastening said cylindrical members and frames together, a pinion journaled on one of said cylindrical members, an internal gear journaled on another of said cylindrical members which meshes with said pinion and means on said internal gear for operating a pump rod.
3. in a pump jack, a pump, a pump rod, two similarly formed frames, a plurality of cylindrical members clamped between said frames With means for fastening said cylindrical members and frames together and to the pump, a pinion journaled on one of said cylindrical members, an internal gear journaled on another of said cylindrical mem bers which meshes with said pinion, a pin mounted on said internal gear and means journaled on said pin and connecting said puma rod.
' 4. 111 a pump jack, a pump, a pump rod, two similarly formed frames, a plurality of cylindrical members clamped between said frames, with means for fastening said cylindrical members and said frames'k'ogether, means for fastening said frames to said pump, a pinion journaled on one of said cylindrical members, an internal gear journaled on another of said cylindrical members which meshes with. said pinion, a cylindrical member fastened to said internal gear and a rod journaled on said member and connecting the pump rod, GEORGE ALDERSO-N.
