SPECIFICATION forming pal-t of Letters Patent no. 403,042, dated May *7, 188e.

Application filed August 2.2, 1888.

Serial No. 283,480, (No model.)

To all whom it may concern:

Beit known thatLGHARLns ANsoN FRAYER, a citizen of the United States, residing at Keithsburg, in the county of Mercer and State of Illinois, have invented certain new an d useful Improvements in Oil-Cans; and I do hereby declare the following to be a full, clear, and f exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Figure 1 is a vertical central section of the can or Vessel. Fig. 2 is a detail showing in elevation the metallic lower end of the internal and flexible tube. Fig. 3 isa detail in top plan of the valve inthe end of said tube. The object of this invention is to provide a pumping attachment for an oil-can or other vessel; and the novelty consists in an oil-can`r or other vessel of otherwise ordinary construeA`Y tion having exteriorly to and above its nozzle or outlet a pumping mechanism connected and adapted to be operated in connection with` a flexible tube leading to the bottom of theA can, together with valves in said tube, in the nozzle, and in the parts above the nozzle, and

'in the detail of the construction ot the several parts, and in the combination vwith each other, and in the device as a Whole, all as will now bemore fully described, as well as pointed out in the claims.

Having now generally stated the nature and scope of my invention, I will proceed to describe it particularly, reference being had to the accompanying` drawings.r

In the drawings, A denotes any usual o r ordinary oil-can or other vessel for lcontaining liquid, provided with a illing opening, c,. closed in any usual or ordinary Way to provide a suitable vent as well as stopper. Inside this can or vessel is a Iicxible tube, B, extendingto the bottom of the can, and having at its lower end the valve C, seated in the metallic annulus D and provided with a spring', c, about its stem c. This spring operating against the bridge c2, through which the stem passes, the valve is thus held normally closed. In the upper part of the can this tube B is secured upon the nozzle E, which, by its screwthreaded upper end, is fixed within the lower end of the tube F, which belongs to the pum p- 'iineaus of the spring g about its stem g', and

acting against the bridge f, through the upper end ot' which the spindle passes, similar to the construction shown in Fig. 3. Opening into. the side of this tube F, at about its middle length and at right angles to it, is the tube I-I, provided at its outer end With the plunger or valve I, adapted to be operated by the piston rod or stem '11. This stem passes through the screw-cap h, over theend of the tube, and can be worked by one iinger of the 2hand, which grasps the can-handle, the foreiin ger resting on the curved piece 71.', attached to the under side of tube H, and extending downward toward the handle a. The spring L, secured at one end on the inside of tube F and at the other acting against the valve I, serves to hold. said valve normally at the outer end of the chamber I-I. y

On the upper end of the tube F is screwed the lower end, m, of the valve-cage M. Within this is the valve N, which seats on the upper end ot' the tube F, and is kept normally f'fclosed by means of the spring n about its shaft ln', which moves in the bridge m', simi-y lar to the construction indicated in Fig. 3.

The lower end of the discharge tube or spout O .fits over the valve-cage M and is soldered thereto. Its upper end is shown as broken oft.

This invention can be worked in the following manner: llhe operator or user grasps the handle c. With'one hand, his forenger engaging upon. the curved finger-hold h and his y thumb resting upon the outer end of the rod By pushing in this rod. valve or plungerI moved toward the tube F, and its quick retraction by the operation of spring L in the pump-chamber creates a vacuum and serves to open the valve G at the upper.1 end of the flexible tube B and the valve O at its lower end, and draws upward the oil or iiuid from the inside of the can or vessel. So soon as the force of this movement ofthe plunger has been exhausted the spring g, acting on the valve G, seats it, and thus holds within the tube or pipe F-that is, the pump-chamberall or nearly all of the fluid or oil which has been drawn up. Vhen the interior of the pipe or tube F, which I dcnomin ate the pumpchamber, has been filled, the succeeding inward stroke of the piston or plunger serves to force the oil or fluid upward and out through the valve N into the discharge pipe or nozzle of the can or vessel. The valve C will prevent the return of the oil into the can or vessel. The valve G will act to prevent its return into the flexible tube when the plungerrod ceases to operate, and the valve N will prevent the return of oil from the discharge pipe or nozzle. The valves G and N will also serve to close air-tight the pu1np-cha1nber in tube F during the operations of the piston and plunger. The lower end of the metal piece D is so made that it will ai ford at the bottom an opening at all times for the oil to reach the tube when the valve C is open.

Having now described myinvention7 what I claim isl. In an oil-can or like vessel, an internal flexible pipe valvcd at its lower end where it touches the bottom, combined with the .nozzle and with a pumping mechanism above the nozzle and between it and 'the discharge-tube, said pumping mechanism being adapted for operation by the hand grasping the can-hann (lle.

2. In the can A, the internal flexible tube, B, having the valve C at its lower end seated in the annulusD and moving on stem c", and provided with spring c, and combined wi th the nozzle Gl and with the pumping mechanism f above it.

v In an oil-can or like vessel having above the oil-chamber a tube intermediate between the nozzle and the outlet propel', and in connection therewith the 4vacuum -producing mechanism, consisting of the plunger I and its rod and the spring L, attached to the plunger, combined with the pipe B, having the spring-closing valve C at its end, and the valves G and N, respectively situated below and above the said mechanism, substantially as described.

4. In an oil-can or similar vessel, the combination of apumping mechanism exterior to and above the oil-chamber proper, with a flexible pipe connecting with the oil-chamber, spring-valved at its lower end, and a pumping-chamber between the nozzle and outlet or spout, whereby all backflow of the oil is prevented.

5. In an oil-can or like vessel, the internal pipe, B, having spring-valve and annulus D at its lower end, the spring-valves G and N in the portion above the oil-chamber, the pumpchamber F between said valves, the side tube,

H, the piston L actuated as described, the

spring L in said chamber, and the outlet O, all substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES ANSON FRAYER.
