LUBRIOATING DEVICE.
Application filed April 19,
To all whom it may concern:
Be it known that I, Crrnsrnn A. Bacon, a citizen oi the United States, and a resident of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Lubrieating Devices, of which the following is a specification.
This invention relates to improvements in lubricating devices and more particularly to the construction of a device of the character described, embodying the general features and functions of the ordinary type of compression grease cup, together with novel tea tures of construction calculated to overcome certain disadvantages heretofore found to be present-in the devices now in use.
Among the objects of my invention is to provide a lubricant device that is convenient oi manipulation, particularly as regards the removal of the cap for the purpose of replenishing the lubricant. Broadly, this is accomplished by replacing the usual form of screw-threaded cap by an adaptation ot the bayonet joint together with a simple and novel form of tension means designed to maintain the cap in place on the receptacle.
The features embodying my invention are hereinafter fully set forth and in connection with the accompanying drawings, wherein Figure l is a view of the device in eleva- ,tion,
2 is a View device,
Fig. 3 is a view in vertical section of the cap and plunger removed from the receptacle of the device, and taken on line 3-3 of Fig. 4c, and
Fig. 4L- is a detailed view in section taken on line 4-4 of Fig. 2.
The form of lubricating device embodying the features of my invention consists oi a receptacle 1 or body member consisting of a cylindric metal shell provided at one end with a threaded nipple 2 having a comparatively small discharge orifice 3, said nipple being provided with, screw threads and adapted to be attached in the usual manner to the part or mechanism to be lubricated. A cap or closure 4. fits over the open end of the receptacle, said cap being provided with an annular flange 5 adapted to engage and surround the upper margin of the receptacle.
Referring more in detail to the means employed for detachably connecting the cap in vertical section of the Specification of Letters Patent.

- to the receptacle, the same involves the use end portion at right angles thereto termi nating in a slightly enlarged end portion as is clearly shown in Fig. 1. fit the center of the cap is pro vided an opening in which is inserted a bushing 8 which forms a part adapted to retain member hereinafter to be described, and in addition acts as a connection for a tension member, which will now be described. As clearly shown in Figs. 3 and 4:, there is mounted adjacent to theupper wall of the cap and within the same a spring or tension member 9 comprising a central portion having an opening through which extends the bushing S, the latter being provided with an outwardly spread shoulder which acts to retain the tension ineinber rigidly in place and fixed to the cap l. The tension inemberturther con sists of a plurality of radially extending spring fingers 10 which terminate adjacent to the inner surface of the flange 5 of said cap, said spring fingers or the tension. memher being adapted to engage the upper edge if the receptacle when said cap is applied to the receptacle in theact 'ot' detachably connecting the same thereto.
The function of the tension member and the method of connecting the cap to the receptacle will be understood from the following: The cap is first fitted over the end of the receptacle and rotated until the detents 6 enter the locking notches 7 and by applying a slight pressure and simultaneously rotating the cap in a clockwise direction, the detents come to rest in the enlarged ends of the locking notches, as is clearly shown in Fig.1, said enlarged end portion in itself forming an additional locking means inasmuch as it is slightly offset in the direction of the edge of the receptacle.
()bviously, the spring fingers beingfixed to the cap exert a pressure upon the recepto maintain the parts in secure locking en gagement.
In addition to the parts already described the device further comprises a plunger consisting oi a plunger head 11 having a diameter substantially equal to that of the internal diameter 01" the receptacle, said head being provided'with a packing ring 12 of any suitable material. ll-igidly connected to the head 11 is a stem 13 provided throughout its length with screw threads, said stem passing through and engaging the bushing 8 located at the central portion of the cap l. At the outer end of the stem andlocated on the exterior, of the receptacle is a handle 14: adapted to be grasped by the fingers in operating or -manipulating the plunger. Withinthe interior of the receptacle and filling the space between the discharge orifice 3 and the plunger head 11 is a quantity of absorbent material 1.5 of any suitable variety, such as cotton waste,.wicking, or the like.
The purpose of the wicking and the function of the plunger will now be described. A quantity of oil is poured or otherwise introduced into the receptacle by removing the cap together with the plunger, the quantity of oil thus fed to the receptacle being suiiicient'to completely saturate the mass of absorbent material 15. The cap is then applied to the receptacle and connected thereto in the manner heretofore set forth, the plunger being first screwed outwardly to the limit of its movement in order that it will exert very little or no pressure upon the mass of absorbent material. In order to force the oil from the receptacle and through the discharge orifice 3 it is only necessary to screw down the plunger by means of the handle 14, the extent of movement of the plunger being determined bythe quantity of oil desired. Qbviously, by this arrangement the oil will be held in saturation by the mass of absorbent material and will not flow from the receptacle through the discharge orifice so long as the plunger is not operated'to compress the mass of absorbent material. Thusit is possible to maintain oil at all times within the receptacle, which oil will not enter the parts to be lubricated unless so desired by the operator. Furthermore the quantity of oil which may be fed from the receptaclecan be accurately controlled by the operation Oil? the plunger so that the necessary amount of lubricant can be introduced into the parts by a known movement of the plunger. For instance, it may be known to the operator that exactly four drops of lubricant will be discharged by rotating the plunger stem through a quar= ter of a turn and in this manner the operator will know at all times just how much lubricant is being used and thus enable him to properly lubricate the parts.
By employing the specific form of looking device hereinbefore described the operation' of applying the cap becomes exceedingly simple, it being only necessary to rotate the cap until locking engagement is ct lected, the tension of the spring upon the parts assuring the connection between the parts and prevents the loss oi": the cap. Furthermore, by this type of locking means the use of the usual screw threaded connection between the cap and the receptacle is eliminated, this connection being ordinarily the source of considerable inconvenience inasinch as it is often diflicult to properly engage the threads, particularly' where the lu bricating crevice is located in a position in convenient of access.
The features embodying my invention are further set forth in the appended claim.
I claim as my invention:
A lubricating device comprising an open receptacle, a cap fitting over the opening of said receptacle and detachably connected thereto, said cap being provided with a centrally located opening, a bushing fitted in said opening through the medium of an annular groove interfitting with the edge of said opening, a fiat tension spring fixed to said cap by means or" a central aperture engaging the groove ofsaid bushing, and a stem extending through said bushing and havingscrew threaded engagement therewith.
In witness 'whereofll hereunto subscribe my name this 29 day of March, A. D. 1920.
