Patented June' 27, 1933 UNITED STATES asians PATENT oFFicE CHARLES L. WILLIAMS, OF ALHAMBRA, CALIFORNIA, ASSIGNOR TO CHARLES HAAS, F SAN GABRIEL, CALIFORNIA OIL GAN Application med March 9, 1932. Serial No. 597,719.

My invention relates to a spray type of oil can for projecting thin oil under pressure,

and has been particularly designed for the.

purpose of hand spraying vehicle springs. An object and feature of my invention 1s the provision of an oil can in which by the manipulation of one hand the o1l ma be pumped under considerable pressure rom the can to an elongated stem and discharged through a nozzle in the form of a spray.

In this type of device another feature is using a spring for returning the pump por-4 tion of the device to its upward position after each stroke, the action of the spring sucking oil into the pump portion of the can.

Another detailed feature is to have the pump device actuated by a single hand grip device, this being somewhat in the form of a pistol grip so that a pull on the fingers actuates a lever for operating the pump.

Another feature of my invention 1s that v the stem or plunger of the pump-is made tubular and reciprocates with the pump in actuation by the finger operated lever, and the oil pumped and projected flows' through the tubular plunger.

. Another featureof my invention relates to the manner of installing'the pump in an oil can, the whole pump construction being suspended from the neck oja can. y

A further feature of my` invention relates to a swivel intake' tothe pump, this being rotatable" on 'the lower end ofthe -pu-mp' barrc1 to draw the'o'il from the lowest part of the cau should the can `be-tilted to one side.

Still "another Afeature relates to a check valve on vthe outlet to-prevent oil rombeing drawn back into the oil can through `the dis- 2 2 of Fig. l in the direction of the arrows, illustrating the swivel intake;

AFig. 3 is an enlarged sectional view of the discharge nozzle and check valve.

In the illustrations 11 designates an oil can having a tapered top 12 with a threaded neck 13, this neck having a shoulder 14 at the top.

The hand support structure 15 employs a hub 16 which has a threaded socket 1-7 threaded on the neck of the can, there being a packing ring 18 at the base of the socket forming an oil-tight joint at the shoulder 14. The hand grip device has a slot 19 therethrough and a downturned pistol grip handle 20. A pump lever 21 has a finger grip end 22, a knuckle 23 pivoted to the handle at 24, this pivot being in the slot 19 and havlng an operating lever end 25 with a longitudinal slot 26.

A pump barrel 27 is formed tubular and is secured in the reduced socket or recess 28 of the hub 16, this having a tight attachment. The hub is provided with an opening 29, through which extends and operatesv by reciprocating motion the tubular pump plunger 30, there being a leakproof packing 31 surrounding the plunger. A collar 32 is secured to the plunger and has an oHset arm 33 -with a pin 34 engaging in the slot 26. Therefore, on operating the linger end 25 of the pumpvlever 21,. the tubular lunger is rciprocated. The lower end ofp the plunger has a'washer 35 b'earin thereagainst. A perforated plug 36' exten s ythrough the washer and is screw threaded at v37 to the inside of the plunger. has a valve seat 38 with a ball check valve 39 thereon. A leather cup the perforated plug 36, being held in place by ythe head 41 of such plug.

l The bottom of theI barrel is provided with av check valve 42, this having an interior sleeve 43 threaded in the lower end of the barrel 27. There is a seat 44 on which bears the ball 45 of the check Valve. A perforated disk 46 retains the ball in place. A shoulder` 47 connected to the sleeve bears against the lower end of the pump barrel.

The swivel intake has a tubular nipple 48 extending below the shouldered section of the lsleeve 43. This is provided with a series of radial ports 49, and a swivel tube 50 surrounds the ni ple, being retained in place by the head 51 o a plug 52 threaded in the lower end of the nipple, there being a washer 53 or the like intermediate the head. The swivel has a wei hted end 54 and an intake o ening 55 which 1s adapted to be positioned a jacent theV corner 56 at the bottom of a can. The

tube 50 has a section 57 circular in cross section surrounding the nipple. y

The outlet nozzle 58 is provided with a tubular valve tube 59 with a reduced tubular l5 threaded plug 60 threaded in the end portion 61 of the tubular pump plunger, this plunger having a lateral bend as indicated at 62. A valve seat 63 receives the ball 64 of the check valve, this' being held in place by a spring 80' 65 which bears on the end 66 of a foraminated tube 67. This tube issecured to the small inner end 68 of a closure plug 69, which plug has a threaded section 70 threaded on the inside Vof the valve tube 59. The lu has a head 71, and the duct 72 through te plug forms a discharge orifice for the nozzle.. By this construction `the oil is filtered by the screen 67, inflow of oil is prevented by the ball valve 64 andv if there is a sli ht pressure inside the can it is insuiicient to orce oil out p ast this ball, but when the pumping operatlon takes lace the oil may be readily forced past the va ve.

In the operation of the device, after the 38' can has been filled with oil and the hub 16 of the handle structure -15 secured thereto, the oil is pumped by holding the -istol grip end 20in the palm of the hand an operating the finger end 22 of the pumpin lever 21. This gives a movement downwar y of the pump lunger 30, which plunger is forced upwardly y the compression spring 73 bearing on the sleeve 43 and' the head 41 of the lug D36. On the downward pressure, ql whic is past the check valve flows up through the check valve 39, and when the-tubular plun er becomes filled this is ejected throu t e ori- Y ice of the nozzle, opening the chec valve 64..

When the' fingers are released, the spring forces the stem upwardly with the plunger, and on account o the valves 39 and 64 seatlng, oil is sucked upwardly through the lower check valves 45. 'The intake tube 50 may swivel on the lower end of the pump barrel in order to draw oil from the lowest portion of the oil can when tilted.

The perforated plug 36 on the end of the tubular plunger 30 with the leather cup 40 may be considered as the piston of the pump, and the valve 39 carried therebyas a traveling valve in distinction from the standing or foot valve 45.

An important feature of 'my invention in the manipulation and use is that on the grip of the hand when the finger grip is operated the piston is forced downwardly and positively ejects the oil. Therefore, the pressure at whichthis oil is ejected is governed by the pressure exerted by the hand, and a per- P son may control this to spray the oil either the can or oil container into the pump barrel.

An air vent duct 75 is formed in the socket 17. This has a valve therein .formed by a perforated plug 76 forming a valve seat with a ball 77 seated thereon pressed in place by a spring 78. There is a perforation through F the pump barrel to align with this duct, and air vents 79 in the upper part of the pump barrel allow passage of air in and out of the pump barrel. The air vent allows entrance of air into the oil can as oil is pumped out.

Various changes may be made in the details of construction without departing from the spirit or scope of the invention as defined by the appended claims.
