Patented Jan. 2, 1951 OFFICE FLAT LEAKPROOF OILER Walter Grieme, Osawatomie,Kans. Application June 20, 1947, Serial No. 756,065
This invention relates to improvements in lubricating apparatus, and more particularly to a hand pump operated oiler.
An object of the invention is to provide a flat, non-leaking oiler having a pump and a swinging spout that seals itself when the spout is in nonoiling position.
Another object of the invention is to provide an oiler which is conveniently carried ina tool box, a garment pocket or tool bag, that is leakproof, handy and easy to use, provided with a spout that can be swung to either the sides or front thereof, and will house the spout in nonoiling position so that the spout will not protrude beyond the oiler in a dangerous position when not in use.
With the above and other objects and advantages in view, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:
Figure 1 is an elevational view of an embodiment of the invention, partly broken away, to show the pumping mechanism thereof;
Figure 2 is an elevational view showing the spout in oiling position and partly broken away to show filler opening and plug;
Figure 3 is a top plan view of Figure 2;
Figure 4 is a sectional view on the line 4--4 of Figure 1;
Figure 5 is a fragmentary detailed view of the pumping mechanism and spout in non-oiling position;
Figure 6 is the same, with the pump and spout in oiling position;
Figure 7 is a sectional view on the line '|1 of Figure 5 with the spout in closed position;
Figure 8 is the same, with the spout in oiling position toward the front of the oiler;
Figure 9 is the same as Figure 7, with the spout in oiling position toward the side of the oiler and Figure 10 is the same, with the valve in bleeding position to permit oil in the pump to return to the reservoir.
Referring more in detail to the drawings, the reference numeral designates the oiler embodying the invention, which comprises the reservoir or body 2| which is comparatively flat and rectangular in shape. Mounted within the body 2|, which is hollow to contain oil or other fluids therein, is the U-shaped support 22 having a base 23 0f the same widthas the body 2| and which, on the bottom thereof, and the uprights 2 Claims. (01. 222-385) v .t
of the support 22, are of the same width "as the base 23,-and engage the inner surface of the ends and sides'of the body 2|.
The top 25 rests on the upper ends of the uprights 24, and is inset with regard to the upper edge of the body 2| to form a smooth top surface thereon. Centrally thereof the top is provided with a screw type filling plug 26 which is also inset with regard to the top surface of the oiler, and the plug is used to fill the body with oil or other fluids.
Secured to the base 23 of the support 22; in vertical relation thereto is the pump cylinder '26 in which is mounted the piston 21, the stem 28 of which extends upwardly through the opening 29 in the top 25. A rubber sealing gasket 30 mounted in the openings about the stem produces a fluid leakproof seal to prevent the oil from leaking out of the body about the stem 28, and a washer 3| aids in retaining'the gasket in the body; An expansion spring 32 on the stem 28 engaging the top of the cylinder 26 and a disc'collar 33 on the stem forces the piston upwardly, and the stem outwardly ,of the body as shown in Figure fi. A knob 34 on the upper end of the stem provides a contact means for reciprocating the piston 21' to pump oil from the cylinder 26 which enters therein by means of the upper and lower rows of perforations 35 and 35' respectively, and is discharged therefrom by the conduit 36 communicating with the cylinder 26 adjacent the bottom thereof.
The conduit 36, at its opposite end communicates with the valve casing 31, in which is mounted the degree valve 38 having the curved outlet 39 communicating with the pouring or oiling spout 40.
Communicating with the outlet 39, by means of the groove 39', which extends about the valve bodyat the center thereof in a 180 degree are, are'the ports 4|, 42 and 43 respectively, which permit the spout to close all ports, and the groove 39' when in closed position, as in Figure 7, to oil to one side when port 43 is in communication with conduit 36 by the groove 39 as in Figure ,9, or to oil to the other side when port 4l is; in communication by the groove 39' with conduit 36. When port 42 communicates with conduit 36, the spout will oil to the front, and when" conduit 36 is in communication with the perpendicular bleed vents 44 or 44' in the valve, the oil in the pump will be returned to the reservoir. This occurs by reason of the fact that ventsjgfl and 44' have no connection with the groove 39' but just before the spout is returned to closed position, the conduit 36 alining with these vents discharges the oil from the conduit so that the oil will not be discharged from the spout when in closed position. While the aforementioned positions are positive positions, the groove "39 permits the spout to oil at any position through a 180 degrees arc. A threaded lug 38' on the bottom of valve 38 on which the nut 39' is threaded engages thespring washer 4B and retains the valve 38 in the casing 37 by contacting the lower edge of the casing 3'7 outwardly of the valve 38.
Hingedat 45 on the top 25 is a pressure bar 7 4B which extends forwardly of its hinged endto be engaged under the protruding lug 41 formed on the'valve 38 below the spout- 40. Thus the pressure bar 46 which engages theknob-or con tacting means 34 will hold thepiston 2! in inopfrom; sticking outwardly thereof. To further-protect the parts mounted on the top 2 5, a removable ,cover 5] is positioned on the upper edge of the body 21 and retained therein by means of spring latches 52 on the cover 5| engaging the detents or keepers 53, formed on the ends of the body 2L In operation, the cover .51- is removed, and the spout isswung to the position shown in Figure 8 and Figure 9, or the reverse of Figure 9, to disperse oil or other fluid from the ciler. Movement of the spout will disengage the lug 4'!v from the free end of the bar 46, to permit the spring 32 to force the piston and bar upwardly to the position shown in Figure 2. Pressure on the bar 46 will rejciprocate the piston 21 to pump oilor other fluids .out of the spout 40 as desired. When the lubricating operation is completed, the spout is turned There has thus been Provided an oiler which.
it is believed, will accomplish the objects of the invention, and it is believed that the structure and operation thereof will be apparent to those skilled in the art. It is also to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention, and the scope of the appended claims.
Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:
1. A lubricating apparatu of the character described, comprising a hollow body,- a pump in said body adjacent the bottom thereof, said pump comprising a cylinder, a piston mounted. therein, a stem on said piston exmeans for. engaging said stem for the reciprocation thereof to force fluid outwardly of said cylinder through said spout, and means on said valve for engagingthe means 'for reciprocating said piston to retain said piston in inoperative position. 1 Y
2. The invention as in claim 1, wherein means provided on. the means-for-reciprocating said piston for closing the open end of said spout to prevent leakage therefrom.-
