LOUIS E. SHIRAY AND EARL J. W. DE FOREEST, OF ROBIN SON, ILLINOIS.
COUPLING FOR OIL-WELL POWER TRANSMITTING MECHANISM..
Specification of Letters Patent.
Patented .rui 20,1909.
Application filed October 26, 1908. Serial No. 469,539.
To all whom it may concern:
Be it known that we, LOUIS E. SHIRAY and EARL J. W. DE Fonnnsr, citizens of the United States, residing at Robinson, in the county of Crawford and State of Illinois,
side's being difficult and inconvenient to accomplish.
The present invention provides means located in the length of the rods by means of which power is transmitted to the pum s for operatlng the same and which means W1 l'admit of any one of a series of pumps being disconnected'without incurring or exposing the operator to danger, the coupling being easily and quickly engaged by simply throwingpawls into and out of operative position.
For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for eflecring the result, reference is to be had to the following description and accom an ing drawings.
Wh e t e invention may be adapted to different forms and conditions by changes in the construction and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, in
which:
Figure 1 is a detail view in elevation, of a line of rods or transmission devices between a pump and the'power, embodying the invention. Fig.2 lsa top plan view of the coupling means on a larger scale. Fig. 3 is a V16W of the coupling means as seen from the bottom side, parts being broken away. Fig. 4 is a longitudinal section of the slide. Fig. 5 is a cross section on the line 5-5 of Fig. 4, Fi 6 is a section on the line 6-6 of Fig. 3 100 ring to the right, the parts being on a larger scale, the right hand ost being omitted and theleft hand post bro en away.
Corresponding and like parts are referred to in the following descriptlon and indicated The numeral 1 indicates a pum ing jack located at each well for operating t 1e pump. The numeral 2 designates the power house, which is usually centrally located with reference to the series of pumps to be operated. The. jack line is indicated at 3 and the power line at 4, these parts, together with the coupling means, constituting the power transmission. A guide 5 is mounted u on a post or support 6 and receives a rack ar 7 which is coupled to the jack line 3-. The guide 5 consists of a box which'is provided in its top side with an opening in which operates a pawl 9. a
A rod or stay 9 forms anchoring means for the guide 5 and ispivoted at its upper end to said guide and has its opposite anchored to the ground by means of a pin 10. The upper end of the rod 9 is forked, as shown at.11, and embraces opposite sides of 8. lug 12 provided at the bottom side of the guide 5. A
pin 13 connects the forked member's-of the rod 9 with the lug 12 and also for-ms alsupport for the guide by having its end ortions let into 'openin s near the upper en s of the support 6, whic preferably consists of a pair of uprights or posts. The rack bar 7 has a cross head 14 at the end remote from the 'ack line 3 and the end portions of said cross ead are apertured to receive rods 15,- which are connected to the power line 4 and to a slide 16. Ribs 17 are provided'at opposite sides of the rack bar 7 and operate in the vertical walls of the slide 16 and the guide 5.
The ribs 17 serve to centralize the rack bar in the guide 5 and the slide 16, thereby preventing the teeth of the rack bar from ongaging with the upper wall of said parts 5 and 16. i
The slide 16 is similar in construction to the guide 5 except that the bottom is open.
lugs 19 slide 16.
When the transmission or ower transmitting line is in operation tie pawl 9 is projected from opposite sides of the The ro s15 extend alongopposite. sides of the rack bar and are connected to thrown out of action and the pawl 18 serves to connect the slide 16 with the rack bar 7.
pawl 9 is thrown into position to engage with the rack bar, and the pawl 18 is thrown out of engagement with said rack bar being caught on its forward stroke, that is, away from the power house, thereby permitting the slide 16 to travel backward and forward upon the rack bar without imparting any movement thereto and without necessitating stoppage of the power. After repairs have been completed or when it is required to again throw the pump into operation the pawl 18 is moved into position to engage with the rack bar and the pawl 9 is thrown out of engagement with the rack bar so that after the parts have been properly coupled the power may be transmitted to the jack for operating the pump in the manner well understood.
Having thus described the invention, what is claimed as new is:
1. Coupling means for power transmission for oil well pumps, the same consisting of a rack bar having a cross head, a power slide arranged upon the rack bar, rods or bars arranged upon opposite sides of the rack bar and having connection at one end with said power slide, a pawl mounted upon the power slide and adapted to cooperate with the rack bar and a guide held in fixed position and arranged to have said rack bar operated therein, said guide being provided with a pawl to make engagement with the rack bar and hold same inactive when the power slide is disconnected therefrom.
2. In coupling means for power transmission of the character specified, the combination of a rack bar having longitudinal ribs at opposite sides, a-fixed uide arranged to receive said rack bar and iaving grooves in opposite sides to receive the ribs of the rack bar, a pawl mounted upon the guide and arranged to engage with the teeth of the rack bar, a power slide mounted upon the rack bar and having opposite sides grooved to receive the longitudinal ribs thereof, and a pawl carried by said power slide and arranged to cooperate with the teeth of the rack bar.
3. In coupling means for power transmission of the character specified, the combination of a support, a guide provided with a pawl, an anchoring rod, means for connccting said anchoring rod with the guide and the latter with said support, a rack bar mounted in the guide, a power slide mounted upon the rack bar and provided with a pawl adapted to cooperate therewith, said rack bar having a cross head and rods or bars at opposite sides of the rack bar and having connection with the power slide and engaging with the cross head of the rack bar, to form. a support therefor.
In testimony whereof we aflix our signature in presence of twohwitnesses.
