PUMPING AEPARATUS.
Application filed June 4,
'Toallwhomitmwyconcem:
Be it known that 1, JOHN R. SUMAN, a citizen of the United States, residing at Houston, Harris County, Texas, have in-" vented a certain new: and useful Improve ment in Pumping Apparatus, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to pumping apparatus for wells. It has particular application to apparatus for operating pumps in deep Wells for oil or water.
The object of my invention is to provide a pump operating outfit to beused particularly in oil wells which is light and strong in construction and which may be conveniently and quickly installed.
Another object is to provide a combined pumping and hoisting machine whiclf is adapted by its size to be installed on derrick platforms of standard size without modification or change, by employees of limited mechanical skill.
It is desired to simplify the ordinary I standard umping rig so that it will be light and porta leand quickly installed; to.cheapen the cost of equipment of wells and to provide generally a'more efficient and convenient apparatus than is now in use.
Referring to the drawings forming a part of this specification and wherein like parts are designated by like characters of refer- 'vention.
ence throughout the several views, Fig. 1. is a side elevation showing the preferred form of my invention. Fig. 2 is a front elevation as seen from the left of Fig.1; and Figs. 3 and 4: are enlarged detail elevations of the lower end of the pitman used with my in- In the drawing, the numeral 1 indicates enerally the'bed framing for my device.
t one side of this frame and centrally thereof, is secured an upright Samson post 2, forming a support for a walking beam, 3. The walking beam is pivoted to rock at a point on the said beam somewhat to ,one side of the middle point thereof, so as to make one arm slightly longer than the other. The pivot consists of a block4 on the. lower side of the beam in which'is secured a shaft adapted to pivot in bearings 6* formed in the upper ends of plates 7 secured one on each side of the Samson post, 2. The ends 1921. Serial no. 5275.017.
of the walking beam are slotted or forked at 8 the end in use is padded on top at 9 to receve the pump rod connections indicated at 1 The Samson post braced by two inclined -erating the walking beam. I It consists of a horizontal shaft 13 journalled in boxes 14, at each side of the frame 1. Approximately centrally of this shaft is the cable drum 15 mounted idly on the shaft 13 and adapted to be connected for rotation with the shaft by throwing in the dental clutch 16 by means of the lever 17 of ordinary construction; One end of the drum is furnished with the usual *brake drum 18 upon which may be tightened the brake band 19 by the operation of the lever 20, also of the usual construction. A sprocket wheel 42 is keyed to the shaft 13 and serves to communicate rotation thereto. The means for working the walking beam 3 and thus operating the pump comprises crank arms 21 and 22 mounted at opposite ends of the shaft 13.- These crank arms are elliptical in shape and have a series of holes 23 therein at varyingdistance from thecenter of rotation, so as to obtain a long or short stroke as desired. In one of the holes 23 is secured a wrist pin 24 to which is detachably connected the lower end of the pitman 25 which is likewise connected at its upper end to the outer end of the yoke or cross beam 26.
The yoke 26 is secured in'a recess 27 in the walking beam approximately midway I between the pivot 5'and the end thereof.
The connecting rods 25 aresecured pivotally to -the lower outer ends of the yoke. Downwardly extendin ears 28 on the yoke are-received between t e arms of the forked upper end of the pitman and a pin 'is passed through registering openings in the forked ends and the ears 28 respectively, thus forming the pivotal connection.
The manner in which the lower end" of each pitmanis adjustably connected to th'e crank pins 24 is best shown in Figs. 3 and i.
The bearing in which the wrist pin is received is composed of an upper section 29, semicircular in shape, and having a laterally extending lu 30 on one side, A'bolt 31 passes vertical y through said lug and MEI v forthe lower sem1circularate section 33 0f the bearing. Said gate section 33 has a lug 34 adapted to rest on the upper face of the head 32 of thebolt 31 when in closed position. The adjustment of this bolt will. obviously tighten the hearing so as to avoid all lost motion. I
The hinge end. of the upper section of the bearing is formed with an elon ated openingtherein to receive the pivot pin 38 of the gate member. The. upper bearing member is provided with a cylindrical opening forming a seat for a spiral spring bearing on the end of the gate section to force it toward the bolt 31 on the op osite side and thus retain it in locked p sition. This arrangement allows the movement of the gate sec- 7 tion away from theloolt 31, thus accomplishing the release from locked position." The tension on the spring may be adjusted by a threaded plug 40 closing the opening to the recess in which the spring is seated. v
A handle 35 on the lower face of the gate facilitates the handling thereof. The bearing. may be locked in closed position also by a cam-shaped pin 36 "pivoted on said upper section and formed to fit in acurved recess 37 in the bin ed end of the lower section, in an obvious said lower section. The rotation of the cam will lock or unlock the bearing.
The upper. section 29 of the hearing has a central upwardly extending sleeve 41- there-' on. A lateral box 42 on the sleeve furnishes a chamber for grease which may be forced dpwnwardly through ducts to the bearin surface by a threaded plug in the upper en of the grease cup thus formed. v
The sleeve 41 is counter bored and threaded to receive a pin 43 which is screwed therein. A nut 44 serves to lock the pin in desired position relative to the sleeve 41. A similar connection between the pin 43 and the lower end 45 of the pitman rod thus forms a turnbuckle to adjust the length of the pitman when necessary. I I
, In the use of m device it is contemplated that it be installe on a derrick platform as soon as the well is completed and the strainer set. The 'engine used to drill the well may also be used in pumping. The frame constituting thebasewith the power shaft having the drummand crank arm's thereon-is placed in position on the derrick platform; A chain 43 is used t'oconnect the drive sprocket 42 to a sourcev of powersuch as the engine 44. The Samson post and walking beam are then set up.' The walking beam, as has been noted, has two arms of different length so that it may accommodate itself to two difanner to prevent movement of neaaeee ferent sizes of derrick platform. The arm A of the beam adapted to the size of the derrick and the desired stroke will be used for attachment to the pump. A counter-weight of ordinary construction, not shown, may be attached to the other end of the walking beam to balance-the weight of the pump rod and plunger. The pump stroke may be adjusted by 10- cating the. wrist pin in the desired opening in the crank arm. When the pump rod has been attached to the walking beam, the pump may be operated. The engine is started and the rotation of the shaft 13 will start the pump, through the reciprocation of the pitman, the walking beam and the pump rod attached thereto. The-use of two connecting rods instead of the/one that is ordinarily used, manifestly adds strength to an otherwise light structure. 1
When handling pump rods and tubing the p itmen are disconnected and are lifted out of the way by allowing the walking beam to swing up with the pitmen hinged in place. When the drum is used for hoisting, the clutch is applied and the drum will then revolve with the shaft. the tubing or pump rods, the clutch'is disengaged and the weight of the load unreels the hnes under control of the brake which may slow up or stop the drum as desired. This type of pumping rig is capable of speedy and convenient installation and is light and strong in operation. It can be operated with a sprocket chain from the engine shaft instead of the usual costly belt.
The. use of a belt shed or power house will be unnecessary and the cost of'installation will be greatly reduced? Various other advantages will be obvious to one skilled in the ar Without further description. What I claim as new and desire to protect by Letters Patent is:
1. Ina device of the character described,
a shaft, means to rotate said shaft, a pair a Samsonpost, a walking beam pivoted to.
rock thereon, and having arms of unequal For lowering length, said beam adapted to receive a pump rod attachment on each end thereof. means to rock said beam and means on each arm of unequal distance from said Samson post to receive said rocking means. whereby said beam may be adapted to' derricks of difierent sizes.
3. In a device of the character described, the combination of a power shaft, means to rotate said shaft comprising a sprocket wheel fixed thereon and adapted to be connected for operation to a source of power, crank arms on each end of said shaft, a walking beam mounted'above said shaft, a cross yoke on said walking beam, .and connecting rods between the ends of said cross yoke and said crank arms whereby said walking beam may beoperated.
4. In a pump operating apparatus, the combination of a power shaft, means to rotate said shaft, crank arms" on each end of said shaft, a walking beam pivoted to rock above said shaft, a cross yoke on said beam between the pivotal point and the forward end of said beam, a pump rod attaching 15 signature, this the 27th day of May, A.
