CHARLES \V. ELLOTT, OF BOSTON, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO RUFUS S. MERRILL,'0F SAME PLAGE.
SPECIFICATION forming part of Letters Patent No. 265,787, dated October 10, 1882.
Application filed August 29, 1882.
an improvement on my patented oil-dropper5 and it consists in providing the device with a flexible depressible bottom, and in combining with the longitudinally-movable nozzle-closing stem angle or elbow levers, or their equivalent, operated on by a disk or plate connected with said flexible bottom in such manner that when thetlexibiebottom is depressed orpushed inwardly the disk or plate connected therewith shall be caused to press upon the tree ends of the elbow-levers in a direction to cause them to draw back the stem, and consequently open the nozzle. 'The discliarge-uozzle can thus be opened either by pressing on the projecting end ofthe stem, as in the patented device, or by depressing the tlexible bottom.
I desire it to be understood at the outset that I do not claim broadly an oil-can or oiler possessing the characteristicjust specited.
My improvementresidesin thefeatures ofcoustruction and arrangement hereinafter pointed out, whereby the stem is adapted to be operated in either ot' the ways mentioned, and it can best be explained and understood by reference to accompanying drawing, in which is represented a longitudinal central section of an oil-dropper embodying the several features of my invention in their preferred form.
A is the oil-reservoir, made preferably ot' glass and of tubular shape. It is closed atits ends by metal capsB (J, which in this instance are fastened tightly in place upon the reservoir A, so as to prevent escape of oil at the joints. The rear cap, B, is formed with an elastic depressible bottom. The front cap, O, is struck npV or otherwise formed or provided with a central cylindrical depression or chamber, ai. in which the disk or plate b, hereinafter desciibed, is placed,- and can move like a pis- (No model.)
ton in a cylinder. This disk, however, tits the cylinder a loosely, so that oil can pass freely between it and the cylinder. The cylinder a is screw-threaded externally, and upon it is screwed the tip or nozzle c, through which projects the nozzle-closing stem 1. This stem projects at its rear back through the head ot' the cylindrical chamber a, and is of such length that its front end normally extends through and beyond the nozzle, beingheld in that position (in which it closes the nozzle) by a spiral spring, c, confined between the head of chamber a and a tlange on the stem, as shown. In the head ot chamber a one or more openings, j', are formed for the passage of the oil from the reservoir, and these openings (after the tip is unscrewed and removed) can also be used for retillin g the reservoir, or the device can be furnished with a filling-opening at any other convenient point, this being a matter that will depend to some extent upon the size and proportions of the device and the particular use for which it is designed. The dropper shown in the drawing` is intended for sewing-machines. Between the head of chamber a. and the disk or plate b are. interposed two elbow-levers, g, placed on diametrically-opposite sides ot the stem. The interior opposite ends of these levers are connected to the stem by one and the same fulcrnm or pivot pin, h.. Their elbows rest upon the head ot' cylinder a, and theirfree ends project upwardly toward the disk or plate b. with which they are in contact. From the disk or plate b extends a rod, b', which is in operative connection with the flexible bottom ot'the reservoir, being in this instance received in a tubular socket, b2, projecting centrally from the inner face ofthe bottom. When the bottom is depressed or pushed inwardly corresponding movement will be imparted to the rod b'. This will have the elect of pushing the disk b against the outer and free ends of the elbow-levers. As the elbows ofthe levers restV against the head ot' the chamber u', they will consequently move upon their elbows as their fulcrums, with the et't'ect of causing their inner ends to draw back the nozzle-closing stem d against the stress ot' its spring. The elbows are ot' course not fixed to the head of chamber a, and are free to move back and forth IOO thereon as the levers change their positions. As soon as pressure on the bottom is removed the parts return to their normal position.
It will be seen that the device can also be used as a dropper without recourse to the flexible bottom. The stem can readily be pushed back, as ln other oil-droppers, by pressure on its projecting,` point, there being no positive union between it and its attachments and the iiexible bottoni. lt is manifest that the presser which communicates movement from the lieXi# ble bottom to the elbow-levers may be of a shape and construction differing from the disk b. It is also manifest that the presser can be fastened to the flexible bottom instead of being' loosely connected with it, as described; nor is it necessary that the elbow-levers should be located in a recess or chamber in the front of the oilreservoir. The construction hereinbefore described, however, is that which I on the whole prefer.
What I claim as new and of my invention 1s- 1. The combination, with the reservoir, dexiand its exible bottom, of the nozzle, the springcontrolled nozZle-closing stern, the chamber or recess a, the elbow-levers g, having their 1nterior opposite ends pivoted to the-stem and their elbows resting against the head ot' chamber a, and the presser b, a rranged to bear upon the projecting free ends ot' said levers and connected to the flexible bottom, as and for the purposes hereinbef'ore set forth.
ln testimony whereof' I have hereunto set my hand this 28th day of August., 1882.
