POCKET-OILER.

SPECIFICATION forming part of Letters Patent No. 774,328, dated November 8, 1904.

Applicationflled May 5, 1904, Serial No. 206,437. (No model.) I

To all 1071 0172, it may concern:

Be it known that we, AUeUsT F. MEIssEL- BACH and WILLIAM MnrssnLnAon, Jr. citizens of the United States, and residents of 26 Prospect street, Newark, county of Essex, State of New Jersey, (whose post-office address is also the same,) have invented certain new and useful Improvements in Pocket-Oilers, fully described and .represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to furnish an oil-dropper which may be carried in safety in the pocket and which is adapted for use in oiling clocks, phonographs, sewingmachines, and similar small articles when repairing the same away from a workshop. The receptacle may be made cylindrical, square, or flat and is preferably made of a metallic shell, with integral bottom and a screw-socket secured upon its mouth; but the other features of the invention are independent of this particular construction.

The invention will be understood by reference to the annexed drawings, in which Figure 1 is a side View of the complete device, which is drawn of the natural size. Fig.

2 shows the screw-plug or stopper detached.

from the cylinder to exhibit the oil-lifter wire. Fig. 3 is an edge view of the lower end of such wire. Fig. 4: is an enlarged View, in section where hatched, ofthe parts at the upper end of the oil-dropper. Fig. 5 is a central vertical section of the blank for the threaded socket in the first stage of its construction. Fig. 6 shows the same with the marginal flange turned downward in readiness to engage with the top of the cylinder. Fig. 7 shows an alternative form for the receptacle.

In Figs. 1 and t, a designates thereceptacle, made of'a brass shell having integral bottom and provided at the mouth or top end with a narrow flange b. A screw-socket is attached to the mouth of the cylinder by engagement with such flange, the socket being first formed from a disk of sheet metal by punching the central portion downward, as shown in Fig. 5, thus forming a cylindrical body 0, in which the thread is subsequently cut, and a marginal flange (Z, which is subse: quently engaged with the flange b by bending the margin of the flange downwardly, as shown in Fig. 6, and the parts are so proportioned that the body 0 of the socket fits within the cylinder, as shown in Fig. 4, and the down: wardly-bent flange (Z fits just outside of the narrow flange b on the cylinder. By suitable tools the edge of the flange (Z is then bent beneath the flange 7/, as shown in Fig. 4, which engages the socket firmly with the receptacle [a The interior of the socket is threaded, as shown in Fig. 4c, and a plug e is fitted to such screw-thread and provided with a flange f to press a packing g upon the top of the socket. The outer side or face of the flange (Z is formed with a groove h and the collar f with an annular ridge 6, which forces the packing into the groove h, and thus forms a tight joint. The packing is first fitted tightly upon the screw-thread of the plug a and is thus carried permanently by the plug, and the forcing of the packing into the groove 71/ prevents the packing from being pressed outwardly,which would loosen it from the plug and render it liable to be lost.

The plug is formed with a knob j upon its outer end for screwing it into the socket. The plug carries the oil-lifter, which is formed of a wire 71/, with the point flattened, as shown in Figs. 2 and 3, and cut to form a diamondshaped point Z. The wire is made to reach the bottom'of the receptacle a or cylinder (0, as indicated by the dotted lines in Fig. 1, and is thus enabled to utilize the oil when reduced to the bottom of the receptacle.

The flattening of the point greatly increases the surface and the adhesion of the oil thereto when the lifter is raised from the receptacle, and the diamond-shaped point serves to direct the oil accurately upon any spot to which it is to. be applied.

Fig. 7 shows the receptacle of flat form with round neck of sufiicient thickness to form the screw-socket by cutting a screw-thread directly in the neck, and the end of the neck is bent into an integral flange, having the groove h therein. In this figure the knob on the plug is lettered the wire lifter 7c, and the packing g. The operation of the oil-dropper is precisely the same with this construction as with that shown in Fig. 4.

The device is exceedingly durable in character and cheap in manufacture and is of such shape and construction as to be readily carried in the pocket without danger of leakage.

We are aware that it is common to employ a pointed wire as an oil-lifter and to secure such pointed wire to a plug of elastic material inclosed within a sheet-metal cap, and we do not, therefore, claim such a construction, but have made a specific claim to the attachment of the wire lifter directly to a solid metallic plug having a knurled head upon the body and an annular flange or collar projected from the body to compress a packing upon the neck of the receptacle.

Having thus set forth the nature of the invention, what is claimed herein is 1. The oil-dropper having the screw-socket at its end, the solid metallic screw-plug e fitted to the screw-socket and having the oil-lifter wire is with diamond point secured directly in the solid metal plug, the plug being formed with the integral knurled head 1', and the collar f projecting outside of the knurled head and the plug, to compress a packing upon the neck of the receptacle, as herein shown and described.

2. The oil-dropper provided at the mouth with an annular seat havingthe annular groove it therein, and the screw-plug 6 having the oillifter k, the packing-washer 9 carried by the screw-plug, and the collar f upon the plug provided with the annular ridge 2 adapted to press the packing into the groove 7b.

3. The oil-dropper having receptacle with external flange at the mouth, a screw-socket threaded internally and having a flange larger than the flange upon the mouth of the receptacle permanently engaged therewith, to make the screw-socket a permanent attachment to the receptacle.

4. The oil-dropper having receptacle with annular circular flange 6 at the mouth, with the screw-socket 0 having thread upon the inner side only, and having the flange d projected beyond the flange b and bent around the edge of such flange beneath the same, whereby the socket may be first threaded internally and afterward made a permanent attachment of the receptacle.

5. The oil-dropper having a cylindrical body formed of a metallic shell with integral bottom, and provided at the mouth with the flange [2, the screw-socket fitted upon and engaged with such flange and having the groove it upon its end, the screw-plug having the oil-lifter 2:, the packing-washer g carried by the screwplug, and the collar f upon the plug provided with the annular ridge 2' adapted to press the packing into the groove h.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
