a double-acting pump.

*UNirED lSTAT-Es PATENT O EEIOE.`

POWER PUMP-HEAD.

State of California, have invented new andV useful lm rovements in Power Pump-Heads, of which t e following is a specification;

Myinvention relates to improvements inpump-heads, and especially in those designed for use vwith double-acting deep-well umps of the type shown, for instance, in my Fatent No. 737,274, dated August 25, 1903.

The obj ect of my invention is to provide a power-pump head which will be very simple in construction,` easily set u and easlly knocked down forpshipment, w `ch is adaptable for either single or double acting pumps, anddwhich will be powerful and absolutely r1 1 Y glt consists of the parts and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Y Figure 1 is a side elevation, in partial section, showing my pump-head associated with Fig. 2 is an end elevation, 1n partial section, of the pump-head at right angles to view of Fig. 1. Fig. 3 is a detail in perspective of aside plate. Fig. 4 is a detail showing crank-gears adapted for single-acting pumps.

In carrying out my'invention l construct the frame of the head in four parts, prefer-- ably castv and. suitably bolted together.l As shown, the frame'comprises two end castings A somewhat in the form of an isosceles triangle, with the apex of each casting pro.- vided with a long bearing orvbox 2 for the arbor of a crank-gear 3. The two triangular end castings A are spaced and braced by two side castings or plates B, having inwardly-projecting lugs 4 provided with perforations registering with corresponding perforations in the legs of the end castings A.y

Tie-bolts 5 extend through the several perforations of both, end frames and across the side plates, as shown. .Both side and end castings are flanged at thebottom, as represented at 6,-and when the bolts 5 have been tightened up and the entire assembled structure boltedl down it is extremely rigid.' In fact, the long tie-bolts 5 are purposely lextended` from end casting to end casting be- Specicaton of Letters Patent. Application l'ed August 16, 1904. Serial No. 220,923.

' cause ofthe ladditional bracing they a'ord.

At the same time the removal'ofthese eight bolts enables the entire frame to 'be quickly y dismantled. The end castings A have a second set of integrally-cast boxes 7, paralleling boxes' 2 and affording bearings for the drive-shaft 8, which receives motion from any suitable source of power. From shaft 8 power is transmitted to gears 3 by means of the inions 9.

T 1e rotary motion of the crank-gears 3 is converted into a vertical rectilinear movement of the sucker-rods 10 of the double-acting pump 1'1 by means of the connecting-rods 12, each having one end pivoted on a wristpin 13 on aV gear 3 and the other end pivoted y to a sleeve-casting 14, slidable on the vertical stationary guide-rod 15, fixed at its ends in a respective end casting A. The lower end ofeach sleeve-casting has a vperforated radial projection 16 for the engagement of a res ectiverod 10.

he pump, while it may be of any type, is i Y here shown ofthe double-acting variety illustrated in the patent previously referred to, in which there are two Youter valved cylinders reciprocal on the stationary valved barrels,

tol

the latter uniting at the to in a common discharge-pipe 17. Each cy inder is suspended from a rod 10 onv the outside of the barrels and discharge-pipe, and the operation of the vrods and cylinders is so arranged that their action of suction and discharge shall be alternate. Thus the sucker-rods and cylinders work on a balance, leaving the weight of the water only to be actuallyalifted, saving the excess power constantly needed in other pumps to raise the extra weight of the -rod and plunger and obviating the strain usual in most pumps on the power. l

The ends of the arbors of gears 3 are each provided with adjustable collars 18, so that snug smooth-runningbearings maybe always maintained. By giving the arbors a long bearing, las shown, a plentiful support for them and the gears is afforded. This pumphead, while shown and described in connection with a double-acting pump ,l is applicable l Fig. 4, may be substituted for the two wristpins 13. rlhis construction saves taking off or loosening from its bearings shaft 8.

Having thus described my invention, what I claim, and desire to secure by Letters .Patent, is

.1. A power pump-head comprising a frame made up of two end castings each approximately in the form of an isosceles triangle and having long bearings integral with each of said castings for the reception of a cranked gear-arbor, crank-gears liournaled in said bearings, interconnecting side castings between said end castings, long tie-bolts passing through the end castings and extending across the intermediate side castings, suitably-guided connecting-rods pivoted to said crank-gears, and means for imparting motion to said gears.

2. A frame for power pump-heads compri'sing end castings substantially triangular in for1n,jjournalboxes in axial alinement disposed at the apices of said triangular castings and intermediate side castings connecting and bracing the end castings and having perforated lugs against which the end castings bear, said end castings having perforations corresponding with the perforations in the said castings and tie-bolts passing through said perloiations and across the side castings.

3. A power-pump-head frame comprising triangular end castings having integral axially-alined ournal-boxes at their apiees, side castings disposed between and bracing the end castings and long tie-bolts passing through the end castings and side castings and extending across the latter.

4. A power-pump-hcad frame comprising triangular end castings having integral journal-boxes at their apiees, separate side castings connecting and bracing the end castings, means for removably uniting said side and end castings and said side and end castings having each base-flanges provided with means for the attachment of the frame to a ixed support.

In testimony whereof l have hereunto sei my hand in presence of two subscribing \\'itnesses.
