Sept. 25, 1956 G. A. WEIMER FORCED OILER WITH RESILIENTLY COMPRESSIBLE BELLOWS BODY Filed May 10, 1952 6564124 f/f/ME? United States Patent O.
FORCED OILER WITH RESILIENTLY COMPRESSI- BLE BELLOWSzBODY Gerald A. Weimer, Minneapolis, Applicatin-May 10, 1952, Serial No. 287,138 .ZClaims. (Cl. 222-415) relation on said. base to permit filling by compression and "subsequent expansion of 'the body and .adaptedto resist-tipping by b'eingjyieldableto impact "in a lateral direction and permitting a steadyflow of oil or other 'liquidtto be discharged under pressure'when compressive forceisexerted on 'theends ofsaid body.
Morespecifically, it'is an object'tojprovide a substantially indestructible re-usable hand oiler constructed without plungers 'ortother'close fitting mechanism and having a rigid .base plateof relatively large diameter with a highlyflexible hollow compressible body member having alternate outwardly-and inwardly extending accordion 'type circumferentiahfolds to form an easilycom- .pressible and normally --expandedb'ellows with adis- .-eharge'spout mountedattheupper end thereof=through which oil of substantially any viscosity may be forcibly discharged :either-b-y drops or ina :steady continuous stream accordingv to the control --of compressive pressure applied between the ends of said bellows.
It is "a further -object -to provide "ahand oilerparticularly constructed for easy manufacture and having a hollow compressible upstanding body member in the form of a normally expanded compressible bellows constructed of soft highly pliable material such as synthetic rubber or the like and securely anchored at its bottom to a rigid base plate of relatively large diameter and at its top to a spout mounting member and forming the only interconnection therebetween, said spout mounting member being adapted to receive as by being threadably interconnected therewith, a discharge spout of any suitable design.
These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views, and in which:
The figure is an elevational view partially in section showing my new hand oiler.
As illustrated in the accompanying drawing, I show my hand oiler which has a hollow compressible body member constructed from alternate outwardly and inwardly extending accordion type peripheral folds to form a normally expanded compressible bellows designated by the numeral 5, and having the inwardly extending peripheral folds 6 with the outwardly extending peripheral folds 7. As best shown in the sectional portion of the drawing, the inwardly extending folds 6 are concavely arcuately curved in cross section and the out- Patented Sept. '25-, 215956 ice,
in cross section. Inthe form of the invention'illustrated,
The bottom portion of thebellowsS has a peripherally formed base attachment flange 8 "and a rigid base [plate 9 made from sheet steel or the likeha's its marginal edge portion crimp'ed over said flange 8 in fixed relation thereto. The upper end of the bellows or body '5 is diminished in diameter to form .an attachment portion or neck 5a having an outlet opening within which the spout mounting member 10 is inserted and whicliihas an outside diameter somewhat smaller than the inside diameter of the inwardly extending folds .6 to permit said neck 5a'tobetelescopically received within the .upper folds v6 when thebellows is in extreme compressedposition to facilitate substantially complete evacuation of the reservoir. Said mounting member '10has an internally threaded sleeve portion 10a adapted tobe closely fitted Within the opening at the top of body '5 andhas an annular circumferentially'formed upper ring 1% extending outwardly from said sleeve "10a and abutting the top edge of said mouth portion or opening of the'bellows 5. A depending attachment flange is adapted to be pressed tightly against the upper marginal portion. of the upstanding attachment portion 5a at the top of said bellows 5 to securely anch'o'r said spout mounting mem ber .10 to said attachment portion 5a and to the body member '5 of which the attachment portion 5a is a thickened integral part.
In the form shown the body orbellows member 5 is constructed of highly flexible synthetic rubber material which is integrally'formed in the desired shape and size as by being molded under pressure. The ends of said body are thenirespectively fixed 'to said base member 9 andspout attachment member '10 as'by being crimped thereaga'inst -by the respective marginal .attachment portions 'ofsaid'basepla'te 9 and spout mount- .ing member 1010 form an easily and. inexp'ensivelyconstructed reservoir for a forced (feed hand oiler. The
spout mounting "member '10 officours'e receives a .dis-
charge spout 1'1 having an externally cooperatively threaded portion 12 and adapted to sealingly engage the annular top portion 10b of spout mounting member 10. The spout 11 is of course hollow to permit the oil to pass upwardly therethrough.
The following is a description of the operation of my new oiler. The hollow body or bellows 5 can be filled either by removing the spout 11 in the conventional manner or by compressing said bellows 5 by applying compressive force between the base plate 9 and sealing flange portion 13 of spout 11 and then submerging said spout in the liquid with which the oiler is to be filled to draw the liquid into the oiler reservoir upon release of the compressive force exerted on the bellows 5 and permitting said bellows to expand. An extremely accurate control of the fluid discharged through the spout 11 can be obtained by subsequent compressing of said bellows and said fluid may be discharged in a steady uninterrupted continuous stream under substantially any desired pressure or may be controllably discharged in a series of individual drops merely by controlling the application of compressive pressure on the bellows 5. The discharge of fluid is of course directly responsive to the application of compressive pressure on the bellows without the interference of any intervening mechanism to produce a lag or require a pumping action. The compressive force must of course be applied between the two ends in order to obtain the desired accurate control of the discharge from the bellows 5. When my oiler is resting on the base plate 9, it will be extremely stable and diflicult to tip over due to the highly flexible body 5. Any transversely applied force striking the upper portion of the spout 11 or body will merely bend the body which will absorb the impact and the base member will remain stably supported on its flat supporting surface.
It will be seen that I have provided a relatively simple yet highly efiicient hand forced oiler having a rigid base plate and a rigid spout mounting member interconnected solely by a normally expanded highly flexible compressible bellows or body 5 whereby an extremely accurate control of the discharge through the spout 11 can be obtained by compressive force being applied between the two rigid members to compress the bellows from top to bottom. My oiler can be easily filled by using the compressible bellows as a suction bulb to avoid contamination and prevent dirt from getting into the oil and said oiler is highly resistant to tipping due to the highly flexible bellows body forming the sole interconnection between the base and spout. There is no mechanism to get out of order and none of the parts from which my oiler is constructed are subject to damage or breakage. It is obviously possible through the exertion of sufiicient compressive force to discharge oil of substantially any reasonable viscosity and therefore my oiler is adapted for use in sub-zero temperatures as well as in relatively hot climates.
It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of my invention which, generally stated, consists in the manner shown and described herein and set forth in the appended claims.
What I claim is:
1. A forced hand oiler comprising an elongate bellowslike body member having a plurality of alternately inwardly and outwardly projecting folds formed throughout the length thereof, a rigid base plate closing said one end of the body, said body member also having a centrally disposed, axially extending neck formed at the other end thereof, the outside diameter of which is less than the inside diameter of said folds whereby the body may be collapsed to engage the base of said neck against the inner surface of said base plate, an internally threaded mounting sleeve disposed'within said neck and tightly received thereby, and having an annular, radially projecting ring at one end abutting the free end of said neck and a depending cylindrical attachment flange joined to the outer edge of said ring and clampingly receiving the free end of said neck, an elongate spout threadedly engaged in said mounting sleeve, said body member being formed throughout of flexibly resilient, self-supporting sheet rubber which is substantially completely collapsible to permit manual urging of said base plate into contact with the base of said neck to expel substantially all of the liquid from the body member.
