IMPROVEMENT IN APPARATUS FOR FILLING OIL-CANS.

To all whom it may concern:

Be it known that I, ELI F. WILDER, of L0 w- Massachusetts, have invented an Improved Apparatus for Drawing Liquids and Filling Small Vessels; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing making part of this specification- Figure 1 being a plan of the apparatus; Fig. 2, a front elevation thereof; Fig. 3, a side eleof the same.

Like letters designate corres in all of the figures.

The object of my invention is more particularly to draw oil from large cans or tanks into small cans or oilers with facility and without overflowing them; but it is applicable to drawin g other liquids in like manner. I

Let A represent the tank, can, or reservoir pondin g parts a pump for drawing the'oil therefrom into the oilers or small cans. In order to fill the oilers with the greatest expedition it is desirable that a single stroke of the pump-piston should accomplish the filling; but to do this properly a uniform quantity should be drawn at each stroke. My apparatus is provided with a gagestroke, which not only draws a uniform but a definitely-measured quantity of oil, and the measure is changeable and adjustable at pleasure. The mode of effecting the measured gagestroke of the pump-piston, as shown in the drawing, is as follows: The piston-rod a of the pump is secured to or connected with a sliding rack, 12, into which a stationary pinion, 0, gears. A vibratory movement is given to the pinion c by a lever, (1, whereby the strokes of the piston are produced. It is evident that by placing limits to the reciprocating movements either of the handle-lever (I, the pinion c, the rack 12, or the piston-rod a, a gaged stroke can be produced. Thus, as represented, the ban dle-lever (1 moves in a slot, f, the extent to which it can move therein being limited in one direction by a pin, g, inserted across the slot in any one of a series of gage-holes, h h. The pinion 0 is shown ection, t, which, in one djustable stop, j; or a uck by a stop, I, adjustas having a pin or pro direction, strikes an a stationary pin, k, is str able on the pinion. The rack Z) is represented with an adjustable stop, on, to strike a stationary part of the frame; and the piston-rod a is shown with adjustable stops it n to strike the top of the pump. Any of these stops may be provided with a scale to indicate exact measurements. The same principle applies if other means are employed to communicate the movements to the pump-piston. Thus, if a vibratory lever is connected directly with the piston rod the adjustable stop may be applied either to the lever, to the piston-rod, or to both.

There is, however, a difficulty in the practical use of a gage-filling stroke arising from the fact that the oilers are frequently brought to be refilled before they are entirely emptied, so that when a quantity of oil sufficient to fill an empty oiler is pumped therein they overflow and waste oil, as well as become besmeared therewith. To obviate this difficulty 1 connect with the filling-pump another pump for completely emptying the oilers before refilling them. Such a pump I have represented at (J in the drawing. This pump is secured upon the tank A, and is constructed so that it will return to the tank the oil pumped from the oilers. This pump is provided with a project ing nozzle or tube, to reach down into the cans or oilers; and a pipe or passage, 1', is represented as extending therefrom down into the chamber below the stationary valve .9, Fig. 2, of the pump, so that the upward stroke of the pump-piston draws the oil from the oilers. The oil thus drawn into the pump is raised to near the top of the pun1p-barrel, and flows therefrom through a pipe or passage, 1, into the tank. In the drawing the piston-rod of this pump is shown connected with areciproeating rack, a, which gears into the same pin ion a that operates the filling-pump, the movements of one pump thus alternating with those of the other; or, if other means of operating the two pumps together are a simple vibratory levertheir pumpingstrokes in ay alterna te. In using the two pumps together I effect a great convenience in filling the oilers by the use of a single nozzle or spout, 12, both for emptying and filling the oilers, so that, when once inserted in them, they do not require to be shifted from their position till they are emptied and refilled; I accomplish this, as represented, by connecting the single employedas by nozzle 12 with a pipe, 11, which communicates with both pumps; and by the use of a stopcock, to, so constructed that by turning it one way communication is opened'between the nozzle and the emptying-pump and cut off from the filling-pump; and by turning the cook the other way communication is opened between the nozzle and filling-pump and cut off from the emptying-pump. Thus, then, when the movements of the pumps alternate, the motion of the operating-lever one way empties the oilers and its motion the other way fills them, the stop-cock, in the meantime, being turned.

A single pump might be constructed to both empty and refill the oilers; but more movements would be required, and therefore the operation would be less simple and convenient than the two pumps with one nozzle and alternating in action.

The stop-cock w, arranged as shown, is operated separately by hand; but it may be connected with the operating movements of the pumps, so as to be turned automatically there- VVhat I claim as my invention, and desire to secure by Letters Patent, is-- I 1.
