SPECIFICATION forming part of Letters Patent No. 795,103, dated July 18, 1905.

Application led January 13,1905. Serial No. 240,916.

To all '1J/71.0111, if; mfrtjl/ concern:

Be it known that we, FRANK VILLMOTT LOw and JOSEPH BROOKS, citizens of the United States` and residents or' Livingston, in the county ot' Park and State of Montana, have invented a new and Improved Oil- Can, of which the following is a full, clear, and exact description.

Our invention relates to oil-cans, and embodies certain constructional details hereinafter described whereby the cost of construction is cheapcned and durability and simplicity are attained.

Our invention vfurther relates to means for maintaining the oil as free from impurities as prlacticable and also preventing the waste of o1 Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures Figure 1 is a perspective view showing our improved oil-can ready for use. Fig. 2 is a sectional side elevation, partly broken away and showing the internal mechanism of the reservoir 4; and Fig. 3 is a fragmentary section through a part of the spout-and-valve mechanism for discharging the oil.

The reservoir or body portion of the can is shown at 4 and is provided with a handle 5 and with a truste-conical top 6, these parts being o1 the usual construction. Connected rigidly with the frusto-conical top 6 is an annular collar 7, threaded internally and provided with a step or shoulder 8, which projects outside of the upper edge of the truste-conical top 6. Fitting into this collar 7 is a cap 10, provided with a portion 9, threaded externally for the purpose, so that the cap may be readily screwed into or removed from the collar 7. Mounted upon the cap 9 and depending therefrom is a frusto-conical screen 11, provided with apertures 12 and with a comparatively large central opening 13. Rigidly secured to the cap 10 and projecting upwardly therefrom is a tubular member 11 of general tapering form provided at itsy upper end with a sleeve 12, Fitting it internally and internally threaded. Another sleeve 13lis provided with a threaded portion 14, which is adapted to screw into the sleeve l2.v The sleeve 13u is rigidly mounted within the lower end of the nozzle 15, which is connected with the tubular member 11l by the threaded portion 14 being screwed into the sleeve 12, as will be understood from Fig. 3. A conical valve 16 fits oil-tight into the sleeve 14, the lower end of which thus constitutesa valve-seat. A longitudinal rod 17, of springwire, is bent substantially into U shape, asindicated in Fig. 2, and is provided with a portion 19, bent outwardly to a point slightly above the handle 5. This portion 19 is provided with a thumb-plate 20. Atensile spring 21 ris soldered upon a sleeve 22, rigidly connected with a vent-pipe 19, provided with an opening 20a. The lower end of the tensile spring 21 is connected by solder at 23 with an air-valve 18, this valve being rigid upon the rod or stem 17. The vent-pipe 19u passes through the cap 10 and is rigidly connected therewith.

Our invention is used as follows: The reservoir 4 being filled with oil, the operator grasps the handle 5 and inverts the can or tilts the same to an oblique position. Then by pressure of his thumb upon the thumbplate 20 he lowers the U-shaped rod 17,slightl y separating the tensile spring 21. This causes the Valve 18 to open the lower end of the ventpipe 19, thereby admitting air through the aperture 20. This same movement causes the valve 16 to recede from the sleeve 14, the lower end of which serves as a valve-seat, so that the oil is again free to pass through the sleeve 14 and out of the nozzle 15. The thumbplate 2() being relaxed, the spring 21 restores the rod 17 to its normal position, thus moving the valves 16 and 18 against their respective seats. The conical screen 10 prevents impurities entering into the tubular member 11a.

By the use of our device the operator is enabled to discharge exactly the quantity of oil desired and may continue to hold the can inverted without the possibility of any additional oil being wasted.

The can may be cheaply constructed. The member 17 being oi' a single piece of springwire prevents the necessity of making a multitude of parts. By unscrewing the spout 15 the Valve 16 is readily accessible, and this is a great advantage, because if anything should happen to go wrong With the valve it can easily be corrected. As it is impossible for the oil to escape except through the action ofthe Valve, it follows that when the parts are in their normal positions no oil can waste from the can, whatever may be the position of the latter. The valves 16 being comparatively near the spout 15 enables the oil to How back into the reservoir i the instant the can is turned into its normal position. It is therefore easy to prevent the oil from congealing within the nozzle 15 or in the tubular member 11, these two parts constituting a composite spout for the can.

Having thus described our invention, we claim as new and desire to secure by Letters Patent The combination of a receptacle provided with an annular collar threaded internally, a cap threaded externally and fitted into said collar, a screen of substantially frusto-conical form connected with said cap and depending into said receptacle, a spout mounted upon said cap, a substantially U-shaped rod provided with a portion extending through said screen and into said spout, a valve within said spout, said valve being opened and closed by movements of said rod, a tube extending through said cap and into the body of said receptacle, a valve member mounted upon said rod and adapted to close the lower end of said tube, a spring connected with said tube and with said valve member for tensioning the latter relatively to said tube, and a thumb-piece mounted upon said U-shaped member for manipulating the same.

ln testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
