UNITED STATES JOHN RAU, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE RAU NOVELTY COM- PATENT OFFICE.

PANY, OF SAME PLACE.

OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 423,812, dated March 18, 1890.

Application liled June l0, 1889. Serial No. 313,703. (No model.)

To 'all whom it may concern.'

Be it known that I, JOHN RAU, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Cans, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, which form a part of this speciiicatiomand in which* Figure Vl is a vertical longitudinal section of the improved oil-can, showing the valve seated; and Fig. 2 is a similar view showing Fig. 3 is a horizontal section on the line 3 3, Fig. 1. Fig. 4; is a perspective view showing some of the parts on a larger scale. n

The present invention relates to oil-cans in general; but it is especially valuable when applied to that class of cans known as feeders, its object being to improve and perfect the can of this class which is shown and described in United States Letters Patent No. 383,370, which were granted to me on the 22d day of May, 1888.

To this end the invention consists in certain features of novelty, which are particularly pointed out lin the claims hereinafter, a

can embodying it being nrst fully described with reference to the drawings, in which- A represents the body of the can, having the customary handle Bnozzle C, and filling orifice D, provided with a screw-cap d. The interior of the bodyAand nozzle C communi cate through an opening E, back of which, within the body, is a diaphragm F, having an opening Gr, through which the oil passes to opening E, and thence to the nozzle, as suggested by the arrow in Fig. 2. Around the opening G the metal of which the diaphragm F is formedis spun or bent up into a iiange H, which constitutes a seat for a valve I, pivotally connected to the forward end of a valvestem J, consisting of a lever fulcrumed at any intermediate point to a bar WV, and engaged at its heel end by a push-rod M, which passes upward through the top of the can and is provided with a push-button O. The push-rod passes through a sleeve N, whose opposite ends are closed by caps U, having central. perforations for the passage of said rod. A spring P, situated within the sleeve and bearing tened end of the valve-stem J, which is provided with an elongated perforation j. A pin p is passed through these perforations and pivotally connects the valve with its stem. The perforation j is of such size as to permit the valve to seat itself perfectly (by gravity) before any pressure is exerted upon it, and also to permit the rounded end of the stem to have contact with and bear upon the top of the valve at X, so that the pressure for holding said valveto its seat will be exerted directly upon the valve itself and not upon its pivot. It is obvious that the elongated perforation to which this action is due may be formed through the ears t', instead of through the stem, and I therefore desire to have it understood that so far as my invention 'relates to this loose pivotal connection it is not, in its broadest sense, limited to the identical arrangement shown in the drawings. Normally, the valve is held rmly upon its seat by a V-shaped spring V, which bears at its angle end V upon the top side of the valve-stem, whence its two arms or branches extend downward to the under side of the bar W, are coiled several times around said bar, and extend rearward beyond it, their extremities being secured to the can at ocx. This rod (or bar) forms a support for the valve-stem J; but said stem and bar are not rigidly connected together, as in my former patent. On the contrary, the stem is fulcrumed to the rod, so that the latter is not moved by the movement of the former. To accomplish this, I secure to the top side of the rod W a metallic saddle S, having a pair of short standards or ears s, which are a sufficient distance apart to admit between them the flattened portion J X of the valve-stem, said ears and stem being perforated for the passage of a pin f, constituting the fulcrum of the valve-stem. This saddle consists, preferably, of a single casting of approximately U shape, with its under side hollowed out, so

as to fit snugly the top side of the rod, to which it is secured by a single screw passing downward through a perforation formed through the lower part of the saddle between the ears. The saddle is thus effectually held against displacement, and as the portion JX of the valve-stem fits snugly between the ears s said stem is held against lateral movement horizontally.

The portions w of the rod lV which are surrounded by the coiled portions of the spring V are reduced in diameter, so that the coils are sunken below the surface of the rod. This enables the rod itself to bear against the bottom directly. If these coils were not countersunk, but allowed to rest upon the bottom of the can, their pressure and friction incident to the operation of the device would soon wear holes through the said bottom.

lVhat I claim as new, and desire to secure by Letters Patent, isy 1. In an oil-can, the combination, with the body, the nozzle, and the perforated valvescat presented inward, of a valve-stem consisting of a horizontal lever fulcrumed at an intermediate point and terminating at one end above the valve-seat, an outward seating valve situated within the can and pivotally connected directly to the above-mentioned end of the valvestem, so as to depend from the under side thereof, a spring operating to force said valve down upon its seat, and a push-rod engaging the other end of the valvestem, substantially as set forth.

2. In an oil-can, the combination, with the body, the nozzle, and the perforated valveseat presented inward, said seat being linclined substantially as shown, of a valve-stem consisting of a horizontal lever fulcrumed at an intermediate point and terminating at one endrabove the valve-seat, an outwardseating valve situated within thc can and pivotally connected directly to the above-mentioned end of the valve-stem, so as to depend from the under side thereof, a spring operating to force said valve down upon its seat, and a push-rod engaging the valve-stem, substantially as set forth.
