PUMP-OPERATING MECHANISM.
SPECIFICATION forming part of Letters Patent No. 592,581 dated October 26, 1897.
Application filed April 17, 1897.
To aZZ whom it may concern.-
Be it known that I, THOMAS J. BLAGG, a citizen of the United States, residing at WVaverly, in the county of- Lancaster and State of Nebraska, have invented a new and use ful Pump-0perating Mechanism, of which the following is a specification.
My invention relates to pump mechanism adapted to be actuated by an air-motor; and the object in view is to provide a simple and efficient construction and arrangement of levers and cooperating parts, whereby the 1'0- tary motion of a driving-shaft is converted into a reciprocatory movement of an intermediate connection to oscillate a system of levers by which motion is communicated to a pump-rod. I I
Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claims. i r

Fig. 3 is a detail front view of the mechanism for adjusting the beam, whereby the frame of the mechanism may be lowered and also showing the cushioning devices for the pump-rod.

form of the apparatus, in which a counterbalanced lever is used as the means of communicating motion to the operating-lever from the driving-shaft. Fig. 12 is detail side View of the lever. Fig. 13 isa horizontal section of the joint. Fig. 14: is a plan view of the form of connection between the lever and chain shown in Fig. 1. Fig. 15 is a detail view in perspective of a portion of the same. Fig. 16 is a detail View of a preferred form of bearing-box.
Similar numerals of reference indicate cor responding parts in all the figures of the drawings.
In carrying out my invention, which is designed especially for use in connection with pumps for deep wells and for irrigating purposes, I preferably employ a tower 1, to an intermediate bar 2 of which is fulcrumed a tilting beam 3,'the cross bars or braces of the tower at its front and rear sides being omitted, respectively at the top and bottom, to allow said beam to be inclined, as indicated by the dotted lines in Fig. 1, to bring the upper end of the beam to a point contiguous to the ground, whereby the mechanism supported by said beam maybe adjusted and repaired without ascending the tower. The means which I employ for accomplishing this tilting of the beam is illustrated in the drawings as consisting of a double drum comprising coaxial drums 4 and 5 of respectively large and small diameter mounted for actuation bya'common crank 6 and held at the desired adjustment by means of ratchet mechanism 7, cables 8 and 9', extending, respectively, from the upper and lower extremities of the beam 3 to the large and small drums and being reeled in opposite directions thereon, whereby when the operating-crank 6 is rotated in one direction the beam is tilted to bring its upper end toward the ground, while with an opposite rotation the beam is returned to its normal or upright position. The platform 10 at the top of the tower is cut away to form an opening 11, in which the head 12 of the mechanism is adapted to fit, said head being carried 'by the beam. To look the beam in its upright position, I employ a latch 3 fulcrumed upon the beam and adapted to engage one of the cross-bars of the tower, and this latch may be disengaged from a point near the ground by means of a lever 3 which is connected with the latch by a rod 3.
The head may be of the tubular construction illustrated in the drawings to receive the upper end of the pump-rod 13, which is detachablyconnected, as at 14, to the pistonrod of the pump, a pump of the ordinary construction being illustrated at 16. The cushioning device is introduced in the pumprod to relieve the upward and downward jars thereof, said device consisting of upper and lower members 17 and 18, which are bifurcated to interlock at their contiguous extremities and are cut away to receive cushioningsprings 19 and 20, which are arranged, respectively, on opposite sides of a pressure-plate 21, carried by the upper member 17. The upper end of the spring 19 bears against a fol-- lower-plate 22, which extends through the bifurcation of. the upper member and is secured to the lower member by means of tension-rods 23. The extremities of the springs fit in sockets 24, formed, respectively, on the pressure-plate 21 and the follower-plate 22. (See Fig. 6.):
The interlocking extremities of the pump rod sections, which are respectively reduced and bifurcated to form the interlocking joint, are slotted in a plane transverse to the bifurcation to: form a guide for the follower-plate, the pressure-plate being secured to the extremity of the reduced portion or tongue of the reduced member, and hence beingguided by the bifurcation of the other member, and therefore when the opposing.sprin.gs are arranged with their contiguous ends seatedupon opposite sides of the pressure-plate and their remote ends seated, respectively, upon the follower-plate and the innerend of the from contact with contiguous members and at. the same time are held from lateraldeflec suitable. bracket 29, which, as illustrated in Figs..1 and 2, is adj ustably mounted upon the frame to. enable its distance from the head to be varied, the adjusting devices consisting of a tongue or extension 'on the bracket fitted in. aslot 31 in the frame-and secured by meansof aboL-t 32. The lever is-also provided with aplnrality of perforations'33 for engagement by the pivot-bolt 34 on the bracket to enable the-,relati've lengths of the arms of the lever 1' to-bevaried to give greater or lessleverage and throw- Thepump-Iever is provided with a laterally-swinging arm 35,.connected with the of the operating-lever and the frame, said section being connected with the frame by means of a vertical pivot 40 and with the body portion of the lever by means of a horizontal pivot 41; also, the connection between the operating and the pump levers consists of a universal joint, preferably of ball-andsocket construction, as shown at 42, this joint being illustrated in section in Fig. 10.
43 designates a driving-shaft, which may I be actuated by any suitable means, such as a wind-wheel 44, and mounted for operation by this shaft isan endless carrier 45, in the construction illustrated said carrier consisting of a chain extending around a chainwheel 46 on the driving-shaft and an idle chain-wheel 47, of which the spindle 48 is mounted in bearing-blocks 49, adjustably mounted in the-frame. These bearing-blocks are preferably fitted in slots 50 in parallel end bars 51 of the frame and are secured at the desired adjustment to maintain the carrier at the desired tension by means of securing-bolts 52' and engaging nuts.
In Fig. 7 a slightly-modified arrangement is shown, wherein the driving-shaft 43 is connected by intermediate gearing 53 and 54 of the speed-multiplying type with the spindle 55 of the carrier-wheel 46, and in Fig. 10 the driving-wheel 43 is connected by speed-multiplying devices, consisting ofchain-wheels 56 3 and 57 and a chain 58, with the spindle 48 of the upper carrier-wheel 47.
The function of the carrier 45 is to communicate oscillatory motion to the operatinglever 38, the connection between the carrier and the operating-lever consisting of aswivel 59, which is secured to the carrier and is gjointed to the lever, whereby as the carrier Qjtraverses the wheels the operating-lever re- ,ceives a combined vertical and lateral oscilglatory movement, which, however, does not affect the true vertical oscillation of the main or body portion of the pump-lever 27, by reaison of the universal joint 42, by whichv the ioperating-lever is connected with the laterially-movable arm of the pump-lever and the llateral l-y-yielding joint 36, by which the arm 135 of the pump-lever is connected with the lbody portion 27 thereof.
Various means may be employed for con inecting the pump-lever to the pump-rod in addition to the direct pivotillustrated in- Figs. 11 and 2, and of such modified means I have fillustrat'ed one in Figs. 7 and 8, wherein the bifurcated end of the pump-lever is connected with a cross-head 60 on the pump -rod by means of downwardly-extending rods 61, and another in Fig. 9 consisting of a cross-head 62, connected by similar upwardly-extendin g rods 63; also, in Fig. 101 have illustrated a rotary rectangular frame 25, carried by the head 12, instead of the tapered or triangular frame illustrated in Figs. 1 and 2, and, furthermore, in Fig. 7 I have illustrated a frame constructed of metal and consisting of a rod instead of the wood frames illustrated in the other figures.
In Figs. 11 to 13, inclusive, I have illustrated another modified construction of the apparatus embodying my invention. In this form, instead of the carrier consisting of an endless chain 15, I employ a carrier consisting of a lever 6% for communicating motion from the driving-shaft to the operating-lever 3S. Said carrier-lever 6% is of sectional construction, jointed at 65, one of the members being secured rigidly to the driving-shaft and having a counterbalancing-weight 67, while the other member, which is jointed, as described, to said first-named member, is connected by a universal joint 66 with the contiguous extremity of the operating-lever 38. Obviously when the driving-shaft rotates it communicates motion through the lever 6% to the operating-lever 38, the pivoted section of said lever 61 serving to allow said communication of motion without straining or binding, while the weight 67 serves to counterbalance to a certain extent the weight of the contiguous end of the operating-lever. In Fig. 11 I have shown only a portion of the apparatus-namely, the counterbalanced lever 64, portions of the driving-shaft and the frame, and a portion of the free end of the operating-lever 38--to illustrate the means for communicating motion from the drivingshaft to the operating-lever.
In Fig. 15 is shown a detail View of the preferred form of connection between the operating-lever and the chain 45 used in the construction of the apparatus illustrated in Figs.
1 to 10, inclusive. Said chain is provided at the proper point with an enlarged link 68, to which is attached a clasp 69, having ears or lugs which are bent toward each other over the ends of the link and in a bearing 7 O, at the center of which clasp is mounted the stem 71, rigid with the looped end of the operating-lever. (See Figs. 1, 2, 7, and 10.)
It will be understood, furthermore, that the function of the weight 37 is to counterbalance the pump-rods and a portion of the resistance caused by the suction of the pump, whereby the resistance of the wheel is equalized and the latter is caused to rotate at a uniform speed.
It will be understood, furthermore, that while in the drawings I have not shown any specific form of bearings for the several shafts suitable bearings may be employed, such as that illustrated in Fig. 16.
Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the spirit orsacrificing any of the advantages of thisinvention.
