OIL GAR.

Application filed November 19, 1927. Serial 170. 234,401.

This invention relates to an oil can and particularly to an oil can embodyin a pump to force the oil under pressure rom the nozzle or spout.

The general object of my invention is to rovide an oil can of' the indicated character improved in various particulars and especially with respect to the pump and oil chambers communicating with the pum and with the oil spout, the assemblage eing characterized by simplicity of construction, and the removabilit of the discharge tube, pump and oil cham rs as a unit to facilitate the cleaning of the parts, and characterized further by efiiciency in use.

The nature of my invention and its distinguishing features and advantages will clearl appear as the description proceeds.

Re erence is to be had to the accompanying drawings forming part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is avertical section of an oil can embodying my invention;

Figure 2 is a sectional plan view on the line 2-2 of Figure 1;

Figure 3 is an elevation of the spout and its securing means; and

Figure 4 is a side elevation of the removable unit including the oil can cover, the

' discharge tube, pump and .oil chambers associated with the tube.

In carrying out my invention in practice in accordance with the illustrated example, the can 10, usually cylindrical and having a bottom 11, has secured to the bottom centrally thereof a plug 12, the lower reduced end of which is fl ed over at 13 against the under side of th d bottom 11 to hold said plu in place. The numeral 14 indicates a disc arge tube, the threaded lower end of which is screwed into pl 12, as at 15. A shell 16 having an inwar ly directed flange 17 at the top is loosely held between the rigid collar 18 on the tube 14 and a nut 19 on the tube at the under side of said flange 17.

pump and the discharge The numeral 20 indicates lateral openings in tube 14 near the lower end thereof. The shell 16 seats on top of plug 12, and tapped into the shell at one side is the open end of the lateral tube 21, the other end of which 1s closed. At the opposite side of shell 16 there 1s tapped into shell 16 a second tube 22 having an oil inlet '23 at the outer end controlle by ball valve or other check valve 24 under pressure of 'a' coil sprin 25 whlch abuts at the end op ite half 24 against a screw 26, or equiva ent abutment.

Tapped into the upper side of tube 2L is the reduced threaded end 28 of a pump cylinder 27 in which operates a piston 29, the rod 30 of-which connects by a ball 31 and socket 32 with said piston 29. The rod 30 of the plunger or piston 29 extends upward- .ly through the removable cover 33 of can body 10. A pin 34 or the like may be employed as a stop to limit the upward movement of the piston 29 through cover 33. On the rod 30 also is a felt washer 35' held tightly against the top of cover 33 about the rod 30 to/ prevent leakage, pressure being applied/Thy a coil spring 36 on said lunger rod. An operating arm 37 is placed on the reduced en 39 .of rod 30 and held against displaceme t by a cap nut 38.

The numeral 40 indicates the filling neck on cover 33, said neck having a screw cap 41.

The upper end of tube 14 s provided with a spout 42 secured to said tube 14 by the following devices: A nut 43 is screwed to the u per threaded end of discharge tube 14 and receives a cap nut' or bonnet 44 which has an inwardly directed flange. 46 and bears downwardly on flaring flange on the lower end of s out 42 to give a'tight fit and prevent leal age. The outlet assage 47 at the top of tube 14 is controlled by a ball valve 48 or other check valve subject to the pressure of a spring 49 upon the same, said spring abutting at its upper end against transverse pin 50 disposed transversely in the s out.

With the above described assemblage, movement upwardly of the plunger rod '30 and an upward movement of the plunger 29 will create a vacuum in tube 14 and tube sections 21, 22. The oil is thereby drawn into inlet 23, flows through tube 22 and can then pass freely around tube 14 inside of shell 16 in addition to more or less passing throu h the lateral openings 20 and 114, the oi then flowing on through tube section 21 and into the cylinder 27. The downward pressure on rod 30 through the medium of the arm 37, or equivalent device, will cause valve 24 to be seated in addition to the seat' tendenc of the springl25 on said ball 24., e oil nds escape t rough the passage 20 and through lateral inlet 114 in the discharge tube 14 so that oil will be forced upwardly in the discharge tube 14' and through passage 47 at the upper end' thereof, the pressure of the oil serving to lift the check valve '48 against the pressure of sprin 49 so that oil passes to and throu h t e spout 42 under pressure A ew turns of the dischargmtube 14 tothe left will disconnect the same from the I plug 12, the tubeseetions 21 and 22 being revented from turning with the tube 14 y reason of a holding yoke 51, or equivalent members, disposed at opposite sides of the tube section 22. Witlhthe tube 14 un.

screwed from plug 12 said tube 14, shell 16, tube sections 21 and 22, pump cylinder 27, pin er 29, pump rod 30 and cover 33 may 1i ed as a unit, the lifting action being brought about b the nut 19 eng 'ng the flange 17 of shell 16 and causing t e complete pumpin assemblage and discharge spout to be li ed as a unit. The spout 42 may be removed by unscrewing the nut 43 from the threaded upper end of discharge tube 14. Important advantages result from the described construction by reason of the removability of the internal parts as a unit so that they can be cleaned or repairs made of any of the interior parts. vanta e also is that the intake/valve 24 is near t e bottom of the oiler body and also it is located at the opposite side of the oil can from the handle 110, and due to the tiltin of the can when grasped by the side han e 110 the oil accumulates a jacent to the oil inlet 23 and ball valve 24 so that the oiler may be relied upon to function efiectively until the oilis substantially dispensed from the oiler.

An advantage also, as will be observed, is that the pump is located adjacent to the handle 110 so that the plunger 30 may be operated by the thumb of the hand grasping said handle. The ball and socket connection 31 and 32 of piston 29 and piston rod 30 prevents binding in the-operation of sad ro It is an advantage also that the working parts are close to thebottom where they will be usually surrounded by oil, which results in a more positive action of said workin arts. Further, all the internal arts 0 t e can, as described, may be prouced on an automatic screw machine mak-- ing it convenient to manufacture and at the same time holding the manufacturing costs at a low figure.

I would'state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without de artu-re from the spirit of the invention as efined in the appended claims.
