IDOUBLE-AC TING-PUME POWER HEAD.

Application filed Dotober 13, 1919. Serial No. 330,181.

To all 10710922 it may concern Be it known that I, CHARLES L. Knssnnn, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Double-Acting- Pump Power Heads, of which the following is a specification.

My invention relates to a power head for w double acting pumps and the objects of my invention are: first, to providea power head for pumps of this class in which the downward stroke of both plungers is more rapid than the upward stroke; second, to provide a power head of this class in which the upward stroke of one plunger leads and laps over the stroke of the other plunger so that both plungers move in one direction during a portion of one stroke; third, to provide a power head of this class which is very simple and economical of construction, durable, compact, highly eflicient, easy to operate, easy to install and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly'set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application, in which:

Figure 1 is a side elevational view of my pump power head showing portions in elevation to facilitate the illustration and Fig. 2 is a side elevational View at right angles thereto.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The plunger rod 1, plunger rod 2, casing 3, stuffing box 4, crosshead 5, crosshead 6, connecting rod 7, connecting rod 8, shaft 9, shaft 10, gear 11, gear 12, pinion 13, main drive shaft 14, sheave 15, bracket 16 and base 17 constitute the principal'parts and portions of my pump power head.

The base 17 may be of any shape or form, preferably constructed of concrete and secured thereto is bracket 16 which is provided with bearings for the

shafts

9, 10 and 14 in certain spaced relation to each other as shown best in Fig. 1 of the drawings. It will be noted that each of the shafts are pro= vided with a pair of bearings as shown best in Fig. 2 of the drawings. Mounted on the one end of the shaft 14 which is the main drive shaft is a sheave 15 for receiving the power from any driving mechanism. Mounted on the other end of this shaft 14 is a pin ion 13 which meshes with a gear wheel 12 secured on the extended end of the shaft 10. This gear wheel 12 meshes with another gear 11 of the same diameter so that the power is transmitted from the sheave 15 through the shaft 14 and gear 13 to the gear 12 and gear 11. It will be noted that the shafts 9 and 10 are preferably spaced some distance on opposite sides of the plunger rods 1 and 2 and the shaft 9 is preferably placed above the shaft 10. Pivotally connected to the gear 11 is a connecting rod 7 which extends downwardly and which is pivotally connected to the crosshead 5 which is secured to the upper end of the plunger rod 2, which plunger rod is a hollow plunger rod and in which is reciprocally mounted the plunger rod 1. This crosshead 5 is provided with a stuffing box 5 adapted to provide a tight joint between the two plunger rods 1 and 2, and prevent leaking and the upper end of the casing 3 is provided with a stuffing box 4 to provide a tight joint between the plan ger rod 2 and the'casing 3. To the upper end of the bracket 16 is secured a bearing member 16 which serves as a support for the upper end of the rod 1. To the gear 12 is pivotally connected the connecting rod 8 which extends upwardly and to its upper end is pivotally connected the crosshead 6 which is secured tothe rod 1. It will be noted that the connecting rod 7 serves as a pull or tension rod while the rod 8 serves as a push or compression rod. It will also be noted that the journals on the gears 11 and 12 on which the one end of the connecting rods are mounted are so positioned with relation to each other that the one connecting rod moves substantially in the opposite direction as the other, except during a portion of each upward stroke of each plunger or connecting rod when said strokes overlap each other.

Though I have shown and described a particular construction, combination and arrangement of parts and portions 1 do not wish to be limited to this particular construction, combination and arrangement but desire to include in the purview of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction there is provided a' double acting pump power head in which the two drive gears are in certain spaced position from the plunger rods so that the one serves as a pull rod and the other as a push rod, that the device as a whole is very simple and economical of construction and easy to install, durable and eflicient.

It is further obvious that with the spacing and positioning of the gears 11 and 12 and with the positioning of the connecting rod journals on said gears, as shown and tie scribed, there is provided a pump power head with double acting, oppositely moving plunger rods in which both move in the same direction during a portion of one stroke.

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

1. A power head for double acting pumps, including a supporting frame work, a pair of pump rods, a pair of intermeshing gears revolubly mounted one above the other on said supporting framework, an equal .distanoe on opposite sides of one of the pump plunger rods, a connecting rod connected with the lower gear and extending upwardly and its upper end engaging one of the pump rods and a connecting rod connecting with the upper gear extending downwardly and its lower end connecting with the other pump rod, said connecting rods and said pump rods lying in a common plane, whereby said power head is simple and compact and the plunger rods will travel faster in one direction than in the other and both plungers move in one direction during a portion of one stroke.

2. Apower head for double acting pumps, including a supporting framework, a pair o pump ,rods, a pair of intermeshing gears revolubly mounted on one side only of supporting framework on opposite sides of one of the pump plunger rods and positioned so that the .aXle of one is considerably above the axle of the other, a connecting rod connected with the lower gear and extending upwardly and its upper end engaging one of the pump rods, a connecting rod connecting with the upper gear extending downwardly and its lower end connecting the other pump rod, said connecting rods and said pump rods lying in a common plane and means for driving one of said gears, consisting of a pinion meshing with one of said gears, a shaft revolubly mounted on said framework and a drive wheel on the opposite side of said framework from said pinion, whereby said power head is simple and compact and the plunger rods will travel faster in one direction than in the other and both plungers move in one direction during a portion of one stroke.

3. A power head for double acting pumps, including a supporting framework, a main drive shaft revolubly mounted therein, a pinion secured to said drive shaft, at one side only of said framework, a gear revolubly mounted on an axis spaced at one side of the pump rods on one side only of said framework intermeshing with said pinion, another gear equally spaced on the opposite side of said pump rods above said first mentioned gear intermeshing withsaid gear, a crosshead secured to one of the pump rods, above said gears another crosshead secured to the other of the pump rods below said gears, a connecting rod, connecting said first mentioned gear with the upper crosshead, and a connecting rod connectingsaid second mentioned gear with the other crosshead, said connecting rods and said pump rods lying in a common plane whereby said power head is simple and compact and the plunger rods will travel faster in one direction than in the other and both plungers move in one direction during a portion of one stroke. 7

4C. In a power head for double acting pumps, the combination with a solid pump rod and a hollow pump rod telescopically mounted thereon, of. a supporting framework positioned at one side only of said pump rods, intermeshing gears revolubly positioned on said framework between said framework and said pump rods and one positioned above the other on opposite sides of the solid pump rod, a connecting rod connecting with the lower gear and extending upwardly and its upper end connecting with the solid pump rod, another connecting rod connecting with the upper gear and extending downwardly and its lower end connecting with the hollow pump rod andineans for driving one of said gears, said connecting rods and said pump rods lying in a common plane whereby said power head is simple and compact and the plunger rods will travel faster in one direction than in the other and both plungers move in-o'ne direction during a port-ion of one stroke. 7

In testimony whereof, I have hereunto set my hand at San Diego, California, this 6th day of October, 1919.
