UNITED STATES PATENT mm.

BEAM ADJUSTER.

Application filed December 13, 1926. Serial Ho. 154,470.

This invention relates to so-called beam adjusters, a mechanism that is employed in the pumping of Wells, said mechanism being used for connecting an operating member,

13 such, as awalking-beam, to the clamp that holds the polish rod of the pump.

An object of the invention is to permit of displacement of the beam adjuster stem from the walking-beam or other operating memw ber,.while, at the same time, insuring against complete disconnection between the operating member and said stem.

Another object is to improve the construction for mounting the stem on the operating 35 member.

Further objects and advantages will appear in the subjoining detailed description. The accompanying drawings illustrate the invention:

Fig. 1 is a perspective view of a beam adjuster, constructed in accordance with the provisions of this invention, a fragment of the operating member, with which the beam adjuster is associated, being shown in broken 35 lines. M

Fig. 2 is a perspective view of the saddle with the locking pin in place.

Fig. 3 is a perspective view of the stem.

Fig. 4 is a perspective view of the bottom plate.

There is provided a saddle comprising a flat plate 5 and'upturned flanges 6 along one of the longitudinal edges of the plate. At its opposite ends the plate 5 is provided with longitudinal extending slots 7, the pur ose of which will be mentioned hereina er. From the underface of the plate 5 projects spurs 8 adapted to penetrate the upper face of the operating member, a fragment of which is indicated at Ain Fig. 1.

The plate is provided with an opening 9 and the flanges 6 are on opposite sides of said opening. Projecting from the outer faces of the flanges 6 are ears l0 and 11 through which projects a pin 12, said pin serving to close the outer end of the opening 9. The pin 12 has a head 13 at one end adapted to engage the car 10 and said pin has near its other end a shoulder 14 adapted,

when the pin is turned to the position shown in Fig. 1, to engage the ear -11 so as to prevent disengagement of the pin fromv the ear 7 pin'12 is turned to the position shown in Fig. 2 and then moved endwise toward the car 10. The shoulder 14 will prevent withdrawal of the in 12 from the car 10.

Seated on t e upper face of the plate 5 are flanges 17 that project laterally from a stem 18 and projecting up from sald flanges is an eye 19 which may be engaged b a hoisting tackle when it is desired to disp ace the stem from or replace the stem on the operating member A. The stem 18 is adapted to extend through a vertical slot B in the end of the operating member, in a manner well understood in this art, and the flanges 6 prevent sliding of the flanges 17 01f of the plate 5. I v

The. lower'end ofthe stem 18 may be con structed in any suitable manner for'yconnection with the polish rod clamp, not shown.-

18 has spaced furcations 20 through which extends a pin 21 held in place by a head 22 at one end and a removable cotter pin 23 near its opposite end. The means for connecting the pin 21 with the polish rod clamp, not shown, may be of any suitable construction and is not illustrated nor described in this specification as it constitutes'no portion of the present invention.

There is provided on the under-surface of the operating member A, a bottom plate 24 having at its outer longitudinal edge a flange 25, which, in this particular instance, projects downwardly. The plate 24 is provided near its opposite ends'wlth longitudinal extending slots 26 through which project spurs 27 of hook shaped members 28 which extend vertically along the side faces of the operating member A and have their upper ends enscrew threaded onto their upper. ends nuts 29 which lieabove the plate 5. In thisinstance, washers 30 are interposed between the nuts 29 and the late 5. It will be apparent from Fig. 1 t at the spurs 27 are driven into the underface of the operating member A. p

,In this instance the lower end of the stem gaged in the slots 7. The members 28 have In assembling the beam adjuster on the operating member, it is desirable to so position it that the stem 18 will hang vertically, and be in axial alignment with the polish rod of the pump when the-operating member is substantially .in horizontal position. Accordingly, in mountin the beam connecter on the operating mem er, the plate 5 will first be placed in position on the upper face of the o crating member and then the stem 18 will place d in'position and connected with the polish rod clamp in a manner well understood in this art. If, after thus connecting the stem 18, said stem should not hang vertically when the operating member is substantially horizontal, the plate 5 will be moved lengthwise of the operating member until vertical hanging of the stem 18 is obtained. If the plate has-been correctly positioned, the bottom plate 24 will be placed in position against the underface of the operating member and the hookshaped members 28 will then be assembled in position as shown in Fig. 1 and the nuts 29 ti htened. In ositioning the plate 2 1, care will be taken to have the flange 25 engage the stem 18 when the operating member is substantially horizontal so that, when the operating member is swinging on the upper half of its up-.

stroke, the stem 18 will be held against swinging inwardly toward the fulcrum point of the o crating member, thus avoiding any apprecia 1e bending of the polish rod. On

-. the lower half of the downstroke of the stances, the stem'18 will be prevented from disen the opemng' 9 in the late 5 b the pid l i i It is to be noted that the innei faces of the flanges 6 extend aslant down ward and inwardly so that, in event of the flanges 17 being unseated from the plate 5 by a quicker descent-of the 0 rating memher than the stem 18, upon e nextsubseuentupstroke of the operatmg' member the flenges lf will be properly gui ed'into position on the plate 5 by the flanges 6;
