My invention relates to improvements 1n hand oilers, and more particularly to pumpactuated hand oilers having nozzle-equipped delivery spouts.

b To the above end, generally stated, the in vention consists of the novel devices and combinations of devices hereinafter descrlbed and defined in the claims.

In the accompanying drawings, which .1l-

l lustrate the invention, like characters 1ndicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a view principally in elevation showing one form of the invention;

F ig. 2 is a View principally in section, taken centrally through Fig. 1, on the axis of the pump;

Fig. 3 is a view corresponding to Fig. 1

but showing another form of the improved oiler; and

Fig. 4 is a view corresponding to Fig. 2, but taken centrally through the oiler shown in Fig. 3. y

Referring first to the invention as illustrated in Figs. 1 and 2, the numeral 5 indicates a cast oil receptacle havinga removable cast dome-like cover 6 detachably secured thereto by screw threads 7. The receptacle 5 and its cover 6 are provided with knurled circumferentially extended bandlike raised surfaces`8 and 9, respectively, by which said receptacle and cover may be held when screwing said cover into the receptacle or removing the same therefrom.

Y The oiler is provided with a C-shaped handle 10 attached to the receptacle 5 by means of upper and lower transversely divided clamping rings 11. The ends of the handle 10 extend between the ends ofthe clamping rings 11 and are secured thereto by means of draws bolts 12 inserted through aligned eyes in said ends, and which bolts hold the clamping'rings 11 frictionally contracted onto the receptacle 5. The lower clamping ring 1l is mounted in a circumferentially eX- tended groove 13, formed i-n a raised band .14 on the receptacle 5, and holds the handle 10 in its proper position in respect to said receptacle. Formed in the cover 6 near the top thereof is a filling opening15 through which oil x may be poured into the receptacle 5, and which filling opening is normally closed by a screw plug 16 having a knurled head and an air vent 17. AA gasket 16 is interposed between the cover 6 and the head of the screw plug 16.

A straight upright coupling 18 having an aXial passageway is secured into a bossed opening 19 in the cover 6, and a gasket 2() is interposed between said cover and a shoulder on said coupling. The lower end of an upright spout 21 is'screwed into the upper or outer end of the coupling 18, and which spout and coupling have knurled circumferentially extended surfaces 22 and 23, respectively, by which they may be held while being turned. A detachable, adjustable nozzle 241, having a knurled surface, is screwthreaded into the upper end of the spout 21. Obviously, by turning the spout 21 in respect to the coupling 18 or by turning the nozzle 24 in respect to said spout, the direction in which oil may be discharged from said nozzle may be varied, at will, while holding the oiler by its handle 10.

Within the receptacle 5 and Cover 6 is a depending casing 25 having an intermediate oil. intake chamber 26. The upper end of the casing 25 is screwed onto the lower or inner end of the coupling 18 and has in its upper end portion a valve chamber 27. A depending intake pipe 28 has its upper end screwed into the lower end of the casing 25 with its lower end terminating close to the bottom of the receptacle 5 and having in its upper end a valve chamber 29. A gasket 30 is interposed between the under side of the cover 6 and the upper end of the casing 25 to form a tight joint between the coupling 18 and said casing. To form a tight joint between the lower end of the casing 25 and the intake pipe 28, there is interposed between said two members a gasket 31.

The intake pipe`28 opens into the valve chamber 29 and a port 32 connects said chamber to the oil intake chamber 26, and a port33 connects said chamber26 to the Vvalve chamber 27 which in turn is connected to the spout 21 by the coupling 18. The intake pipe 28 is normally closed by a spring held check valve 34l in the valve chamber 29 .to prevent af return iow of oil from said chamber to the receptacle 5 through the intake pipe 28.V This check valve 34 is mounted in the valvev chamber 29 and rests on a seat 35 formed in the upper end of the intake pipe 28. A check valve 36, mounted in the valve chamber 27 and resting on a. seat 37 formed with the upper end of the port 33, normally closes said port to prevent a return flow of oil `from the valve chamber 27 to the valve intake chamber 26.

A cylinder 38, of a cylinder and piston pump, extends radially into the cover 6 in a slightly inclined position and is in the same plane with the handle 10. rlhis ,cylinder 38 is loosely telescoped through a sleeve 39 which is formed with the cover 6 and extends both inside and eutside thereof, and the inner end oi said cylinder has screw-threaded engagement with the casing 25 and opens into the oil intake chamber 26. Telescoped on the outer end of the pump cylinder 38 is a head 40 having screwthreaded engagement with the sleeve 39. Mounted in the pump cylinder 3S is a piston 4l to which the inner end et a piston rod 42 is attached, and which rod works through an axial opening in the head 40. On the outer end of the piston rod 42 is a thumb piece 43 and a spring 44 is compressed between an internal shoulder in the pump cylinder 36 and the inner end oit the piston 41 and holds said piston in the outer end of the pump cylinder 38 with its rod 42 projected. A gasket c45 is interposed between the casing and a shoulder on the inner end portion oil' the pump cylinder 38 to Jform a tight joint between the intake chamber 26 and interior of the receptacle 5. rlhe thumb piece 43 is located directly over the handle l0 so that a persen holding the oiler by said handle may engage the thumb piece with his thumb and depress the same against the tension of the spring 44.

The suction or intake stroke of the piston 41 lills the'oil chamber' 26 with the oil from the receptacle 5 and is produced by the spring 44, and at which time the check valve 34 opens and the check valve 36 remains closed. Ilhe compression or discharge stroke of the pump is produced by depressing the thumb piece 43 to move the piston 4l against the tension of the spring 44 and thereby force the oil in the intake chamber 26 through the spout 2l and discharge the same from the nozzle 24, and during this stroke ot the piston, the check valve 34 remains closed and the check valve 36 opens. Upon releasing the thumb piece 43, the spring 44 will again return the piston 4l to normal position and again produce a suction stroke to refill the oil intake chamv ber 26 from the receptacle 5.

0bviously, by unscrewing the cover 6 from the receptacle 5, access may be had to the interior of said cover and receptacle for the purpose of cleaning the same or making any repairs or adjustments. Aside from the receptacle 5 and its handle, all ofthe parts of the oiler are carried by the cover 6. rl`he various parts of the oiler are closely litted Vwith tight joints therebetween, and the action of the valves 34 and 36 as well as the cylinder and piston pump are very positive in their action, and if desired oil may be discharged from the receptacle 5 with considerable force and thrown a considerable distance. By turning either the spout 2l or its nozzle 24, oil, as previously stated, may be discharged in any desired direction, thus making it extremely easy to oil parts of machines or fill oil cups that are diicult t0 reach or located in inaccessible places.

Referring now to the invention as shown in Figs. 3 and 4, the numeral 46 indicates a cast oil receptacle having a removable dome-like cover 47 detachably secured thereto by screw-threads 48 and having a gasket 49 interposed therebetween. rlhe receptacle 46 and its cover 47 are provided with knurled circumferentially extended bandlike raised surfaces 50 and 5l, respectively, by which said receptacle and cover may be held when screwing said cover onto said receptacle or removing the same therefrom.

ln the cover 47 is a filling opening 52 normally closed by a screw plug 53 having a knurled head, and through which opening oil y may be poured to lill the receptacle 46. A gasket 54 is interposed between the cover 47 and head of the screw plug 53, and an axial bore in said screw plug ailords an air vent Extending upward from the top of the cover 47 is a screw-threaded nipple 56. A substantially pf3-shaped handle 57 has its upper end portion bent horizontally over the cover 47 and provided with a large eye through which the nipple 56 projects and connects said handle to the cover 47. The lower end of the handle 57 is secured to the receptacle 46 by means of a transversely divided clamping band 58, the ends of which embrace the lower end of the handle 57 and are secured thereto by means of a draw bolt 59 inserted through aligned eyes in said handle andk ends of the clamping band 58. V

A coupling 60 is loosely telescoped into the cover 47 through the nipple 56 and is provided with an intermediate collar 61 which extends over the nipple 56V and is secured thereto by means of a union 62. A gasket 63 is interposed between the nipple 56 and collar 6l. intake tube 64 has its upper end portion telescoped into the lower end portion of the coupling 60 and is secured thereto by means of a packing nut 65. rllhe lower end of the oil intake tube 64 is locatedrjust above the bottom of the receptacle 46. lnV the upper end portion of the coupling 60 is a valve chamber 66, in the bottom of which is a valve seat 67 normally closed by a ball valve` 68 yieldingly held closed by a spring 69.

A casing 70 has its lower end portion crewed onto the end of the coupling 60, and which casing is provided with an inter- The upper end of an oil Y mediate oil intake chamber 71, and in the chamber 72. A port 73 connects the oil intake chamber- 7l with the valve chamber 72 and has in its upper end a valve seat 74 on which rests a ball valve 75 yieldingly` held closed by a spring 76. rlhe lower end of a spout 77 is screwed into the upper end of the casing 70 and a packing 78 is interposed therebetween. The upper end of the spout 77 is provided with a laterally curved nozzle 79, and which spout, near its lower end portion, is provided with a knurled circumferentially extended surface 80 by which said spout may be turned in the coupling 60 to position its nozzle 79 in any desired rotated position in respect to the oiler.

A horizontal radially disposed pump cylinder 8l, located directly over the handle 57, is screwed into a bossed Opening in the casing 70 with its inner end opening into the oil delivery chamber 7l, and which cylinder has a knurled head 82 applied to its outer end by means of screw threads. Mounted in the pump cylinder 8l is a piston 83 secured to a piston rod 84 working through an aperture in the cylinder head 82 and having on its outer end a thumb piecel A spring 86 is compressed between the well of the chamber 7l and piston 83 and normally holds said piston in the outer end of the pump cylinder 8l, and when said piston is moved to produce a compression stroke said spring returns the same to normal position and produces the suction stroke thereof. A gasket 87 is interposed between the casing 7 O and the collar on the pump cylinder 81.

The action of the oiler just described is the same as that of the oiler illustrated in Figs. l and 2 and the check valves 68 and 75 are arranged to operate in the same manner that the check valves 34 and 36 operate:

That I claim is:

l. An oiler of the kind described having a receptacle with va displaceable cover, a coupling detachably secured to said cover, a casing detachably secured to said coupling and having an intake chamber, a detachable intake pipe leading from the bottom of the y receptacle to said chamber, a check valve normally closing said pipe, a detachable spout leading from said `coupling, a check valve normally closing said spout, and a cylinder and piston pump detachably connected to the casing and having communication with the chamber.

2. An oiler of the kind described having a receptacle with a displacea-ble cover, an upright coupling detachably secured to the cover and extending both above and within the same, a casing in the receptacle detachably secured to the inner end of the coupling and having an intake chamber, an intake pipe detachably secured to the casing and leading from the bottom of the receptacle to the chamber, a spout detachably secured to the upper end of the coupling, a check valve normally, closing said pipe, a check valve normally closing the spout, a sleeve on the cover, and a cylinder and piston pump, the cylinder of said pump being mounted in said sleeve, detachably secured to the casing and having communication therewith.

In testimony whereof I affix my signature.
