Our presentinvention ap'pertains generally to improvements in the art of 011 cans, lubricators and the like, commerciall known as lunger cylinder oil pumps, an specific y to a double acting device of this char acter, as described in the present specification and illustrated in the accompanying drawings.

The invention consists essentially of the novel features pointed out-broadly and cifically in the claims for novelty following a description containing an explanation in idetail 0 an acceptable form of the inven- More specifically, our invention is analogous to hand actuated plunger cylinder oil, pumps of that type designed to pump oil, from either end. of the oilreceptacle. The rincipal object of our invention is to provide an ,eflicient' pump of this character, extremely simple in construction, easy to manufacture and inexpensive from a maintenance view int.

Briefly, it inclu es dual parallel stationary ball-valved cylinders, both communicatwith a common discharge spout. A reciprocatable unit comprising a plunger cylinder and a piston, operate in con unctionwith said stationary cylinders to pump oil through the same. This pum unit is operated by a thumb actuated crumed lever mounted upon the receptacle cover in convement proximity to the receptacle handle. The novel characteristics and advantages as of our invention will be apparent by perusing the following specification in conjunction with the drawings hereunto annexed in which:

Fig. 1 is a transverse medial vertical section of an oil pump constructed in accordance with an acceptable embodiment of our invention, and

p Fig. 2 is a similar view showing certain of the components in a relative position.

The receptacle with which my invention is associated may be of any approved design such as illustrated in the annexed drawings and generally indicated by the numeral 3,

thesame being provided with a detachable cover 4 which is retained in position by a locking ring 5, said detachable cover and locking ring having-no direct bearing upon the subject matter of the present invention.

A spout 6 is secured to the cover 4 and the receptacle so held, upon is provided with a prolongation 7 which.

constitutes the stationary primary cylinder of the pugs). The lower end 8 of this cylinder is 7 uced to form a seat for 'a ball 9 tensioned thereagainst g, the latter abutting the fixed abutment The pumping unit includes a plunger cylinder 22 which fits closely about the primary cylinder 7. Its lower end is reduced to provide a valve seat 23 against 24 seats, movement of which is limited by the cage 25. This plunger. cylinder is tensioned downwardly by a coil spring 26 the upper end of which abuts the lower end of the primary cylinder 7, while its lower end by the coil spring,

which the ball t ereagainst by the abuts said cage 25 and constrains the latter Y in the position shown. An arm 27 is welded or otherwise secured to the plunger-cylinder 22 and is provided with a piston 28 mounted 'upon its u r end, which isreciprocated longitudin y of the secondary cyhnder 13 upon reciprocation of the plunger cylinder 22.

A push rod 29, arranged parallel with the prima cylinder 7, is welded to the plunger cylinder 22 and extends through the sleeve 30 on the cover 4. A lever 31, fulcrumed on the bracket 32 is pivoted to said push rod by the member 33. This lever 31 is arranged in convenient proximity to the receptacle handle generally indicated at 34 so that the operator of the pump may conveniently actuate the same with the thumb of the hand.

The lowermost position of the pump un t is clearly shown in Fig. 1. In this p os1t1on it will be noted that the lower extremlty of the plunger cylinder 22 extends in close rox1mity to the bottom of the can and to t e place where the oil flows when the can 1s held vertical or is inclined slightly forwardly, as is customary in use. In pumgmg oil with epresslon of the lever 31 to the position shown in Fig.

'2, the plunger cylinder 22 is carried longitudinally of the primary cylinder 7. When the lever 31 is relieved of pressure, the coil spring 28 will plunge the plunger cylinder 22 into the oil, which forces the ball 24 from the valve seat 23, so that the chamber in the plunger cylinder 22 is filled with oil, Upon the succeeding upward stroke, the pressure of the oil forces the ball 24 against its seat and the ball 9 from its seat so that the oil will be forced into the primary cylinder 7 and be discharged through the spout 6, The ball 16 constitutes a closure for the by-pass 14 preventing the oil from being forced into the secondary cylinder 13. When the receptacle is held inverted or in an inverted inclined position, the oil accumulating at the top of the can is drawn into the secondary cylinder 13 when the lever 31 is relieved of pressure and the coil spring 26 forces the plunger cylinder 22 and the piston 28 downwardly. Upon the succeeding stroke, the piston 28 is advanced towards the ball 20 adapted to co-act with the valve seat 19 and the oil contained within the secondary cylinder l3 forces said ball to close and is forced past the ball 16 into the primary cylinder 7, forcing the ball 9 to seat against its seat 8, and then through the primary cylinder 7 and out the discharge spout 6;

From the foregoing it is obvious that we have provided an oil ump which is efficient in operationin that 1t will pump oil from the receptacle irrespective of whether the same is held vertical or inverted; in which the parts are comparatively few and may be manufactured without elaborate and extensive facilities, and in which the parts will function for extensive periods without appreciable wear or breakage.

While the preferred embodiment of the invention has been described it is to be understood that minor changes in the details of construction, combination and arrangement of co-operating elements may be resorted to Within the scope of what is claimed without departing from the spirit of the invention.
