QPEOIFICATION formingpart of Letters Patent No. 670,509, dated March 26, 1901. Application filed January 26, 1901. Serial No. 44,849. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM H. H. ERWIN, acitizen of the United States of America, and a resident of York, county of York, State of Pennsylvania, have invented certain new and useful Improvements in Oil-Cans, of which the following is a full, clear, and exact description, in which- Figure l is a vertical section of the can complete; and Fig. 2, a detailed section enlarged, showing'the actuating-spring and adjustable stop.
The object of this invention is to provide simple devices for controlling the flow of oil from the can, so that it may be accurately fed in copious or limited amounts, as occasion may require, whereby all wastage of oil is prevented, as more fully hereinafter set forth.
Referring to the drawings, a designates a valve-rod extending up through the spout and provided with a conical valve 1) onits upper extremity, which normally seats in the conical end of the spout, and thereby normally shuts off the flow of oil at the extreme end of the spout. The other end of rod (1 is bent laterally at c and straight upward at d, this upward extension passing up through an opening in the removable screW-plugc of the can. The upper end of rod dprojects above plug a and is threaded for the reception of a sleeve f, which is in turn externally threaded for the reception of a threaded stop-nut g. The lower end of sleevefworksin an opening in plug 6, and between a loose follower h, abutting against the lower extremity of said sleeve, and an inward-turned flange t', formed on the lower end of a tube j, is an actuatingspring 7a, which surrounds rod 61 and is inclosed in said tube j. The tube j depends from plug 0, and its lower open end is practically closed by rod at, so but little oil can enter said tube when the can is inverted. As will be observed, the spring normally keeps the valve closed by pressure upward upon the lower end of sleeve f through the medium of the follower, and the tension of the spring may be increased or decreased by screwing the sleeve downward or upward on rod d, as
the exigencies may require.
To prevent the valve being forced against its seat at the end of the spout so hard as to controlled. To vary the amount of oil fed,
the stopgis adjusted upon sleeve f, the higher it is adjusted the more copious being the feed. In this manner the feed may be regulated positively and will not depend upon the varying pressure of the operators finger upon the sleeve f, thereby enabling the feed to be positively regulated to a nicety to suit the work and to avoid wastage and scattering of the oil.
It will be observed that the device is so ex-' tremely simple in construction as to permit it to be applied to the ordinary hand-oilers now in use without adding materially to the cost of their manufacture.
It will be observed that the valve-rod a is thinned between the valve b and bend a, so as to render it flexible. The object of this is to enable the rod to conform to the curvature of a curved spout Where such form of spout is employed.
It will be further observed that a feature of importance lies in the fact that the tube j extends into the can and not only affords a iting the movement of the valve-rod. A further featurethat contributes materially to the utility is that the regulating-stop is accessible from the exterior of the can.
Having thus fully described my invention, what I claim is- 1. In a hand-oiler, a can provided with a spout, a valve-rod extending up into the spout from the interior of the can, a rod connected to said valve-rod inside of the can and extending to the exterior of the can, a tube inclosing said rod and extending into the can, a spring inclosed "in said tube, a sleeve casing for the spring, but also a stop forlimthreaded on said rod exteriorly of the can i 2. In a hand-oiler, a can provided with a removable cap or plug carrying a spout, a valve-rod extending up into the spout and connected to an upward-extending rod extending to the exterior of the can, an externally-threaded sleeve threaded on the upper end of said extension, an actuating-spring, and an adjustable stop-nut screwed on said sleeve, for the purpose set forth.
3. In a llaud-oiler, the combination of aean provided With a spout, a valve-rod extending up into the spent, a tube extending into the can and coinciding with anopeuing therein,a vertically-W0rkiug rod extending through
