JOIIN Gr. BAKER, OF PHILADELPHIA, PENNSYLVANIA.
PUMP.
SPECIFICATION forming part of Letters Patent No. 660,040, dated October 16, 1900.
Application filed Nuvember 9,1898.` Serial No. 695,953. \l\lo model.)
.To all wiz/om zit 71mg/ concern:
Beit known that I, JOHN G. BAKER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Pumps, of which the following is a specification.
My invention relates to certain improvements in pumps of the type used to pump heavy liquids from barrels such, for instance, as molasses or syrups.
In applying my invention to a barrel a suitable hole is made in the head of the barrel and the body of the pump inserted therein, a nd by turning the crank the liquid is forced up through the body of the pump to the outlet and into a suit-able receptacle.
In the accompanying drawings, Figure 1 is a vert-ical sectional view showing the plun-v gers of my improved pump in one position. Fig.`2 is a similar View showing the plungers in the opposite position. Fig. 3 is a sectional view on the line 3 3, Fig. l. Fig. 4 is an enlarged sectional view on the line 4 et, Fig. l. Fig. is an enlarged sectional view of the lower end of the pump, and Fig. 6 is a View of a modification.
A is the tubular body of the pump, having a head A secured to its upper end. Projecting from this head is a tubular extension a, bent so that the fluid will readily iiow into a suitable receptacle. The lower end of the tubular body is screw-threaded, and adapted to this end is a cap B, having a series of perforations h, through which the duid passes to the pump.
Mounted in the lower end of the pump is a seat-block C, having a flange c confined between the end of the body and the cap B. In this seat-block rests the lower end of the tubular stem D. This stem is hollow, open at the bottom and closed at the top. The reduced portion d of the stem has its bearing in the cap A', and to this reduced portion is secured the handle D by which it is turned. Packing a is mounted in the head A and confined by a follower a2. The seat-block C has a seat c, on which rests a ball-valve e. The upward motion of this ball is limited by a cross-bar c2.
The tubular stem D has a series of openings (Z712 d3, through which the fluid can pass as it travels up the pump. Mounted above tubular stem D and are controlled by pivoted blocks g g, mounted on pins secured to the casing A. These pivoted blocks travel iu double spiral groovesf in the plungers F F', so that as the stem is turned these plungers not only turn with the stem, but travel iirst toward each other and then from each other on each side of the central opening d2 in the `tubular stem D. As shown in Figs. 1, 2, and
l, the stem has a longitudinal groove, tov
which is adapted a key or spline on each plunger. In Fig. 6 I have shown a square stern, and there is a square opening through the plungers, and the stem snugly iits this opening, so that the plunger can turn with but will slide freely on the stem.
The operation of the pump is as follows: The pump being inserted in the barrel the handle D is turned, turning the stem D, which carries the plungers F F. As the plungers move from the position shown in Fig. 2 to that shown in Fig. l a certain amount of liquid will be drawn into the lower portion of the pump, and when the plungers move from the position shown in Fig. 1 to that shown in Fig. 2 the entrapped liquid in the pump will be forced through the openings d past the ball-valve e into the center of the stem and out of the openings (Z2 to the space between the two plungers F F. On the next movement of the plungers the fresh liquid will be drawn into the pump and the liquid between the two plungers will be forced through the openings (Z2 past the ballvalve e3 through the openings dsinto the space between the casing and the tubular stem above the upper plunger, and as the tubular stem is turned the liquid will be forced out of the discharge-pipe a. Thus it will be seen that a given quantity of liquid is pumped at each reciprocation of the plungers, and by attaching indicating mechanism to the stem the ICO amount of liquid in quarts, pints, or Vgallons may be indicated.
It will be understood that I may substitute for the crank handle shown any suitable mechanism for turning the stem D, and othervalves than the ball-valves may be -substituted without departing from the invention, and any suitable clamping device may be used to secure the pump to the barrel.
In some instances the stem D maybe solid, and the passages for the liquid may be in the walls of the body A., as shown in Fig. 6.
While my invention is especially adapted for pumping molasses and like heavy liquids, it will be understood that it can be used for pumping any liquid.
I claim as my inventiona 1. Thecombination in a pump, offa casing, f a rotatable stem, two plungers 'mounted with in the casing, the two plungers being arranged f to slide von but turn with the stem, fan inlet-- valve at the bottom of the pump, vaived passages independent cfs-'aid vplungers lcommunicating with the space between and `ab'ove the g plungers through which the liquid pumped' passes successively, a discharge-opening at the top of the pump, and a handle `by which the stem is turned, and ineans for causing the plu ngers to move towardand from eachother 1 as the stem is rotated, substantially as deel scribed.
2. The combination ina pump, Yof la casing, a rotatable tubular stem, two plungers con-1 structed to act between the casing-and stem, f
.turning with, but sliding on said stem, means for reciprocating said plungers, passages and valves in the casing fan-'d in rthe stem ksoar-.-
with the 'space `between the plungers and with the spaces above and below the plungers, two valves in the stem and an inlet-valve at the i base of the pump, substantially as described. 4. "lhecombinati'on `'of the casing, a check-- valve 'at the lower end of the casing, a tubular stem, means for turning said stem, three vopenings at given distances apart in the stem,
cheeky-aives between the sever-a1 openings,
two plungers adapted ^'to the space between the casing and the stem and adapted to t'urn with the stem buit slide thereon, dou-ble 'spiral grooves in lthe periphery of each plunger, blocks adapted to the grooves and mounted on the lcasing so that las the shaft is turned the plungers will be reciprocated, 'substantialliy fas described.,
In testimony whereof I have `signed Vmy name to this specification in the presence of two subscribing witnesses.
JOHN G. BAKER.
