Application filed May 14, 1923. Serial No. 639,000.

To all whom it may concern:

Be it known that we, Pa'rnron E. TABOR and Voi'nn V. KIRKPATRICK, both citizens of the United @tates, said TAnon being a resident of Joplin in the county of Jasper and State of Missouri. and said KIRKPATRICK being a resident of the county of Jackson and Fitate of lviissouri. have jointly invented new and useful Improvements in Pump .lacks, of which the following is a specification. i

This invention relates to pump heads, and has for one of its objects to simplify and in'ipiove the construction and increase the c'lliciency and utility of devices of this character.

l l ith these and other objects in view the invention consists of certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a side elevation.

Fig. 2 is a front elevation.

big. 3 is a vertical section on the line 3-3 of Fig. 2.

Fig. 41: is a section on the line -.i-.4i of Fig. 1.

The improved apparatus comprises a base portion 10 mounted on a suitable foundation 11. a supporting frame comprising upright standards 12 arranged in pairs and in spaced relation, each pair of standards be- 111g connected at their upper ends by inclined head members 13 and intermediate thereof by web members 14;, and the web members connected by a transverse strut or brace 15. The base member 10 is rigidly connected to the foundation 11 as by stay bolts 16.

Mounted for rotation in bearings 13' in the inclined upper parts 13 of the frame, is a crank shaft cranks l8 and 19 externally of the frame members 13 and extending in the same direction, and an intermediate crank 20 midway between the spaced frame members;

lltountcd for oscillation in the spaced frame i'neinbers at their highest point is a pivot shaft 21 and mounted on the ends of the pivot shaft externally of the frame 1nembers are rocker arms 22 and23, while a like rocker arm is mounted upon the same pivot shaft intermediate the frame members. The rocker arms 22 and 23 are coupled havin three cranks two outer respectively with the cranks 18 and 19 by connecting rods 25 and 26, while the intermediate rocker arm 2% is coupled to the intermediate crank 25) by a connecting rod 27. Mounted on the crank shaft externally of the frame members 12 are gear wheels 28. and 2-9.. and n'iounted through the frame members 12 near their rear sides is a main drive shaft 30 carrying pinions 31 and 32 engaging the gears 28 and 29. By this means the crank shaft will be actuated from the drive shaft through the pinions and gears, and the outer rocker arm vibrated in unison and the intermediate rocker arm vibrated alternately with the outer rocker arms. The outc ranks 18 are preferably provided with into al counter weights 33 and 3% as shown.

Attached at 35 to the base 10 is a combined guide nieinliier and support 36 having a rigid sleeve 3'? forn'iing the base portion of a pack ing device including a gland 38 the members and providing liquid tight guiding means for a tubular operating member, a portion of which is shown at 39.

At its outer end the member 36 is formed with a threaded step 4+0 to receive the lower end of a vertica guide rod ii-.1. Attached at 42 and 4.3 to the inclined portions 13 of the frame sides arebracket devices 44. and 45, the latter coupled at their outer upper ends by a transverse tie member 413. The upper end 451 of the guide rod is connected to the tie inemberel-G as by a U-bolt 45?, as shown.

filidable on the guide rod 4-1 is a bracket t? held in position by a cap 48., the bracket having lateral trunnions l9. and a downwardly directed socket to receive and support the upper end of a pump r0d50 which extends down through the tubular pump rod -39, as shown. The trunnions 49 constitute lower pivots to links 51 and 52 which are pivoted at their upper ends at 53 to the adjacent end of the rocker arm 24. By this arrangement the upward and downward movement of the rocker arm 24. will come spondly move the pump rod 50.

Mounted to slide on the rod 41 is another bracket represented as Whole at 54: and held in movable position on the rod by a cap member 55, the bracket having a rela tively large vertical aperture to receive a packing sleeve 56 in which the upper end of the tubular member 39 is secured as by threading, as shown in Fig. 3. The rod operates through the sleeve 56, water tight. by a packing: gland ST.

The sleeve 56 is provided with trunnions 57 operating in half bearings in the bracket to provide for; a certain degree of rocking motion lzietween the parts 5% and 56. to preventcramping during; the movements.

Extendingla erally from the bracket 5 1: are arms the arms having studs 60 and 61 respectirel it their outer ends. it connectingrod 62- is mounted to swing at its lower end on the stud (i0. and pivoted at the upper end at (32) to the rocker arm 22. while a similar connecting rod 1? I is mounted to swing at its lower end on the stud (l and pivoted at its upper end at 5 to the rocker arm :23.

The tubular member 39 are adapted to be coupled to a pumping element, not shown. and when motion is applied to the drive. shaft 4 0. the. rocker arms 24; will be Sl iltiliflJitiiIiFlj, vibra ed to apply mot-ion to the tubular pump rod. while the single rocker arm will apply motion to the single pump rod 50. and in alternation with the tubular pump rod. Thus two separate and independent motions will be alternately imparted to the rods to produce a continuous flow from the pumps to which the rods are attached.

The improved device is simple in construction, can be imuuifactured of any suitable material and of any required size and capacity.

The preferred eml'iodin'ient of the invention is disclosed in the drawings and set forth in the specification. but it will he understood that modifications within the scope of the claims may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

Having thus described the invention, what is claimed as new is 1. In an apparatus of the class described. a supporting frame including spaced side members. a shaft journalled on said frame and the rod 50.

and formed with an intermediate crank disposed between the side meiniwrs of the same and (o-acting crank elements externally of the frai ijie side nieml'iers. an inner beam member mounted for oscillation between the frame side members. a connecting' member between the intermediate crank and the inner beam member. co-actinp; outer beam mei'i'ibers mounted for oscillation on the frame mem bers externally thereof. onneetin: neinhers respectively between tl en; elements and the outer beam members. cone? in; pump rods. connecting means between the interme diate beam member and one of said pump rods. and conn(,vd'in l means lietween the external beam members and the other of said pump rods.

2. In an apparatus of the class described, a supporting frame including) st iced side meniibers. a shaft journalled on said frame and formed with an intermediate crank d.i.,.- posed. between the side members of the same and co-actingr crank elements externally of the fran'ie side men'ihers. an inner beam mem ber mounted for oscillation between the frame side meml'iers. a connecting: n ieu'iber between the intermediate crank and the inner beam member, co-actingr outer beam members mounted for oscillation on the frame members externally thereof. connecting; members respectively between the external crank elements and the outer beam members. co-actin pump rods, :1 guide rod supported by said frame. a cross head element slidable on said guide rod and coupled to one of said pump rods. a bracket device slidable on said guide rod and coupled to the other pump ro l. connecting means between the intermediate beam member and said bracket device. and connecting; means between the external beam members and the cross head element.

Tn testimony whereof. we atiix our signatures hereto.

PATRICK E. TABOR. VOYLE V. KIRKPATRICK.
