SPRING, OF WATERBURY, CONNECTICUT; ASSIGNOR T0 THE CHASE COM- PANIES, INCORPORATED, OF WATERBURY, CONNECTICUT', A CORPORATION j :Puur-TYPE oTLER Application filed January 31, 1931. Serial No. 512,580.
This invention relates to improvement in` oilers and particularly to Oilers ofthe type which are provided with pump-mechanisms for forcibly ejecting oil therefrom.V
` The main object of my presentinvention f g is to" provide at a low cost for manufacture' tion consists ina pump-type oiler having i certain details of construction-and combinationsA ofv parts yas will be `hereinafter dej "9415 scribed and particularly recited in the claims.
In the accompanying drawings: Figjl is a view in side elevation of `a pumptype oiler embodying my invention; j Fig.2 is a view thereof in vertical central '20 section but on a largerscale;
Y Fig. 3 is an underside view thereof, with the bottom-plate omitted; j e
v `Fig-111.V is a detail se'ctional'view taken on the line 47--11l of Fig. 2;
"Fig 5 is aviewl inside elevation of the .T piston,`together with its operating-stem, de- ,tached and Fig; Gisf a perspective view of thepump- 30 cylinder detache In the embodiment of my invention herein chosen for illustration, Inemploy an oil-reser- Voir consisting `of-a substantially-cylindrical sheet-metal'body-member 10 provided at its 35 upper fend with a threaded neck 11 for the reception of a vfiller-cap 12 andhaving crimped to its lower edge a bottom-plate 13.
Projecting upward from the sloping shoulo'der-portion l14 of the body-member 10 is a t tubular-spout 15 soldered zit-,16 tothe said Vshoulder-porrtion, and having its inner end "-17 projecting within the interior of the body- `member 10.
45 r Securedto the inner end 17 ofthe spout 15 `by means `of solder 18 is a valve-housing 19 having an axial recess 20 into which the Vlower end 17 of the said spout projects and in which is located a plate-like check-valve 21 a'dapte'dto close a passage `22in'the said valve-housing to prevent reverse flow of oil therethrough, as will hereinafter appear.
vThe said valve 21 plays back and forth Abetween the eXtreme lower edge of theinner end 17 of the spout and the `bottom-wall ofthe recess 20. y Y
Soldered orotherwise secured to the-periphery of the'valve-housing 19 is a pump- 'cylinder 23 depending therefrom and pro- "videdin itslower portion with four (more intersect its lower edge.
for less) slot-likeports 24 which preferably Ho'use'd withnlthe; cylinder 10 'is ia compression-spring 25 bearing at its upper end against the underface of the valve-housing 19 4vand at its lower end bearing againsta ypiston 26 which, as shown, is preferably spherically contoured to permit it to tilt iwithin the said cylinder without occasioning a bind. Y Projecting radially from the underface of the piston 26 is a piston-stem`27 preferably soldered in place and having its outer end bent over to form a hook 28.
The hooked end 28 of the piston-stem 27 "is passed through a perforation 29 formed in one end' of a substantially-horizontal rocking-lever 30 which is pivoted between its ends upon a stud 31 laterally offsetting from a bracket-plate 32 in turn radially projecting toward the center of the"bodymember 10 from the wall thereof, to which it is secured I by means Vof solder, as at 33.
The bracket-plate32 adjacent its lower in- Vner corner is bent laterally to provide a stop-finger 34 engaging with the under-edge of the lever 30 to limit the swinging movevment thereof under the urge of the spring 25.
The endV of the lever 30 oppositethe stem 28 is pivotally connected by means of a stud 35 to the lower arm 36 of a substantially L- shaped operating-plunger 37, the upper arm 38 of which projects outward through a perforation 39 in the shoulder-portion 14 of the body-member 10 and is provided at its eX- treme outer end with a finger-button 40. The upper arm 3S of the operating-plunger 37 slides back and forth through and rocks in a iibrous washer 41 clamped in place against the outer face of the shoulder-portion 14 by means of an escutcheon 42.
I'Vhen the piston 26 is at the lower limit of its movement, the upper ends of the slot-like ports 24 will be uncovered to permit oil to flow by gravity into the interior of the *cylinder 23 above the said piston. Now, when the plunger 37 is depressed by means of its linger-button 40, its arm 38 will slide through the opening` 39 and the washer 41 and, at the same time, rock therein, to depress the end of the lever to which it is pivotally connected and'correspondingly raise the opposite end which plays up and down in one of the ports 24, so as to move the piston 26 upward. This upward movement of the piston first closes the connection between the ports 24 and that portion of the interior of the cylinder 23V lying above the piston, and thereafter positively forces the oil upward through the passage 22, past the check-valve 21 andA thence upward and out through the spout 15.
lVhen pressure is relaxed from the fingerbutton 40, the piston will be depressed by the spring-25 and the parts will be restoredto the positions in which they are shown in Fig. 2,
.io in which the check-valve 21 will be in position to preventthe reverse flow of oil previously forced upward into the spout 15.
Owing to the spherically-contoured character of theV periphery of the piston 26, the same will rock within the cylinder 23 to compensate for the sweep of the lever 30 so that the necessity for a link isobviated. Furthermore, by mounting the plunger 37 so that its upper arm both slides and rocks in the body-member 10, or a bearing secured thereto, v the necessity for elaborate linkage is avoided.
Attention is also called to the fact'that by providing the cylinder 23 with one or more ports 24 which are automatically covered and uncovered by the pist-on itself, the necessity for a suction-valve is avoided, since the oil will low into the cylinder through the said ports by gravity. `When the oil level becomes low, practically the last remaining part thereof may be ejected by tipping the can into a horizontal-'position with its spout and pump-mechanism lowermost.
It will be understood by those skilled in the art that my invention may assume varied physical forms without departing from my inventive concept, andl I, therefore, do ndt limit myself to the specific embodiment here- `in chosen for illustration, but only as indicated inV the appended claims.
I claim:
