HARRY COMSTOCK, OF S'UNLAND, CALIFORNIA.
PUMP-JACK.
Application filed July 22,
To all whom it may concern:
Be it known that I, HARRY CoMs'rooK, a
citizen of the United States, residing at Sunland, in the county of Los Angeles and State of California, have invented new and useful Improvements in Pump-Jacks, of which the following is a specification.
This invention relates to pump apparatus and has for its object to improve the operating jack or head organization of that type of pumps having two suction rods or members connected to respective suction pistons, and the invention consists of the construction and details, forms of which are illustrated in the accompanying drawings and described and claimed herein.
Figure 1 is a side elevation of the improved apparatus, parts being in section.
Fig. 2 is an end view of the apparatus partly broken away.
Fig. 3 is a plan view of the driving mechanism. V
The organization may be mounted upon any suitable framework generally indicated at 2 and the pump plungers or rods are shown at 3 and 4 respectively, the rod 3 being a central stem and the outer rod 4, preferably, being tubular and sliding upon the inner rod 3.
The mechanism for simultaneously operating these rods 3 and 4 and moving them in opposite directions involves a main driving shaft 5 mounted in suitable bearings 6 in one end of the frame, the driving shaft carrying spaced pinions 7--7 which in turn mesh with respective gears 8-8 on short shaft sections 9-9 in appropriate journals 10 in the frame. In this case each of the gears 8-8 are in the form of crank disks and provided with crank pins 11--11 that are set substantially in co-axial relation and are respectively connected to the lower ends of pitman members or connecting links 1212 which extend upwardly and are con nected at their upper ends to wrist pins 13 extending from the ends of a transversely disposed crosshead 14 which, in this case, reciprocates in a vertical plane when driven by the cranks and is slidably guided on the central and upwardly extending suction rod 3.
This crosshead is connected to the inner ends of pairs of toggle or connecting links, there being one set of links 15 on each side of the frame, the links of a common pair 15 diverging outwardly and upwardly, as seen in Fig. l, and being connected at their outer Specification of Letters Patent.

ends to runners 16 in the form of sleeves or boxes that are bored to slidably fit upon lat erally extending supporting rods or guides .17 which aline with each other axially and have their inner ends rigidly connected as by Ts 18 that are connected with standards 19 spaced parallel to each other and extending vertically and lying in a plane in which the center suction rod 3 also extends for convenience of organization and compactness of arrangement.
The lower ends of the standards '19 are shown as mounted in steps 20 at the bottom of the framework 2 and the upper ends of these standards are connected by elbows 21 inwardly turned and transversely braced by a tie 22 which includes a box 23 through which the upper end of the central suction rod is guided.
From the above it will be seen that when the crank disks 8 are rotated the cranks 11 will actuate the pitmen 12 and their upper ends will be moved in a vertical plane and path with a reaction on the toggle links 15, and during the upward movement of the connecting pitmen 12 the toggle links 15 will be thrust outwardly with their runners 16 sliding on the supporting rods 17, and conversely on the downward movement of the pitmen 12 the toggle links 15 will be again retracted and the runners 16 moved inwardly. This inward and outward move ment of the runners 16 is utilized to actuate the suction rods 3-4 and this is accomplished by mounting on the runners 16 two pairs of upwardly extending links, one pair being on each side of the central frame structure 17-19 and shown as comprising upwardly convergent links 24 the upper ends of which are overlapped and mounted upon wrist pins or pivots 25 extending from the ends of a transverse top yoke 26 that is rigidly secured to the upper end of the central suction rod 3. The action, therefore, of the suction rod is that as the runners 16 move outwardly on their bearings 17 the top yoke 26 is moved downwardly carrying with 1t the central rod 3 and conversely as the runners 16 are drawn inwardly the links 24 are forced upwardly and carry the suction rod 3 upward.
Simultaneously with the actions of the top yoke 26 a reverse motion is imparted to the suction sleeve 4 which is provided at its upper end, Fig. 2, with a lower yoke 30 the outer ends of which are provided with wrist or pivot pins 31 on which are mounted pairs of divergent links 32, one pair being disposed on each side of the apparatus, and the upper ends of these links 32 are connected to the pivot pins extending laterally from the runners 16 and on which the upper ends of the toggle links 15 are mounted.
From the above it will be seen that I have provided a simple and effective apparatus for concurrently actuating the suction rods 34 and giving to them opposite motions during the same interim, so that one of the suction rods is moving upwardly while the other is moving downwardly during the same cycle of operation.
Various changes may he made Without departing from the spirit of my invention as claimed.
I claim:
1. A pump jack comprising a pair of telescopic suction rods, a guide frame extending laterally in opposite directions with relation to said rods, runners on said lateral extensions, toggle links connecting said run- 11ers, a crank arm to actuating said toggle links in opposite directions, and toggle links connecting the respective runners to the respective suction rods and extending laterally in opposite directions from said runners.
2. A pump jack comprising a pair of telescopic suction rods, runners arranged for lateral movement relative to said suction rods and at opposite sides of the same, toggle links connecting said runners, a crank arm for actuating said toggle links to move said runners toward and away from one another, and driving connections between said run ners and said suction rods for oppositely re ciprocating the suction rods by said movement of the runners.
In testimony whereof I have signed my name to this specification.
HARRY COMSTOCK.
