[TS-S PATENT OFFICE.
THOMAS M. ADAMS, OF HOUSTON, TEXAS.
PUMP PLUNGER.
Application filed April 11, 1921.
To all whom it may concern:
Be it known that I, THOMAS M. ADAMS, a citizen of the United States, residin at Houston, in the county of Harris and btate of Texas, have invented certain new and useful Improvements in a Pump Plunger, of which the following is a specification.
This invention relates to new and useful im rovements in a pump plunger.
Sne object of the inventionv is to provide a plunger for pumps which has a swiveling connection with pump rod and, is formed with spiralled vanes which cause the plunger to rotate as it is reciprocated up and down. through the fluid, thus causing its friction with the working barrel to wear it uni tormly all around.
Another object is to provide a plunger which is formed of sections which expand against, and closely fit within, the walls oi. the working barrel.
With the above and other objects in view the invention has particular relation to oer-- tain novel features of construction, oper ati on and arrangement oi. part, an example oi which is given in this specification and illustrated in the accompanying drawings. wherein Figure 1 is a plan view of the plunger.
Figure 2 a side view partially in section.
Figure 3 is a plan view of a section oi the plunger.
Figure 4 is a side view thereof.
Figure 5 is a plan view oi a modified form of plunger.
Figure 6 is a side elevation thereof. and
Figure 7 is a bottom end view.
Referring now more particularly to the drawings, the numeral .1 refers to the pump red by means of which the plunger is reciprocated. The lower end of this rod has a head 2 which fits in a socket bearing 3 in the upper end of the stem 4 of the cross head 5. A gland 6 surrounds the rod and screwed into the bearing 3 and holds said stem against detachment from the rod but permits it to turn relative thereto.
The plunger is formed of sections 7, prel erablv three in number. These sections are arcuate in cross section and when fitted together they form a complete plunger which is tubular in form. Each section has one or more tenons 8 at one edge, and at the other edge correspondmg mortises 9, the
tenons of each section interlocking with the Specification of Letters Patent.
Patented May 16, 1922. Serial No. 460,480.
corresponding mortises of the adjacent edge of the adjoining section. The sections are thereby held. in alignment and they are limited in. expansion by the working barrel.
The plunger shown in Figures 1 to 4 have the internal annular grooves 10 and 11.. The cross head 5 has radiating fingers 12 which engage in said grooves to anchor the plunger to the stem 4. The fingers may be engaged into either one oi said grooves, depending upon the length of stroke desired.
The lower end. of the plunger is formed into a seat 13 which is controlled by the ball valve 14; in the usual way. In the lower end oi the plunger there are spiralled vanes 15. The fluid being pumped passes up through the plunger and the current striking against said vanes causes the plunger to rotate and wear uniformly all around, and the pressure of the fluid will cause the plunger to fit closely against the working barrel and prevent leakage past it.
The modified form shown in Figures 5 to .is similar to the other form shown with the exception that the upper ends oi. the sections are formed into lugs 16 whose inner sides have recesses 17 into which the tree ends oi. the fingers 12 it to anchor the plunger to the stem.
That I claim is 1- 1. The combination with a pump rod ol a hollow plunger formed of radially movable sections and having a swivelling connection with the rod, a valve sent within the plunger, and a valve cruitrolling said seat.
2. A. tubular plunger having s 'iiinlled vanes therein, adapted to cause said plunger to rotate when :iiuid is pumped therctliro'ugh. and formed of sections jointed together to expand by internal pressure.
A tubular plunger having spiralled vanes therein a pump rod, means connecting the plunger to the rod permitting a relative rotation of the plunger on the rod, said plunger being formed of radially movable sections joined together so as to permit the expansion oi the plunger by internal pressure.
In testimony whercoi I have signed my name to this specification in the presence of. two subscribii'lg witnesses.
