FILLING AND CHARGING DEVICE Application leid February 6, 1936. Serial No. 426,204.

My invention relates to improvements in filling or charging devices; and particularly to a device for supplying combustible Huid to the interior of cigarette lighters and similar articles so as to keep them in readiness for constant use.

An object of the invention is to provide charging device in which a supply of combustible fluid can be safely stored; and which is adapted for quickly charging a cigarette lighter Without wasting the iuid or risk of accident.

A further object of the invention is to provide a filling and charging device that comprises relatively few parts and is easy to operate, and so constructed that the combustible fluid can be expelled from it and admitted to the inside of a cigarette lighter with a minimum of handling and in the quickest possible manner.

The nature of the invention is set forth in the following description and illustrated in the accompanying drawing which shows one embodiment for utilizing the invention f in practice; but this disclosure is of course intended by way of example only, and I reserve the right to make changes in shape, size, arrangement of parts, and other details without going beyond the principle of the invention or exceeding the scope of the appended claims.

In the drawing, Fig. 1 is a vertical section through a filling and charging device according to this invention.

Fig. 2 is a detail view showing how the cigarette lighter is charged and filled; and

Fig. 3 is a section on line 3-3 ofFig. 1.

The same numerals identify the same parts throughout.

The numeral 1 indicates a vessel or reservoir having the form of a decanter or any other shape with a wide bottom to enable it to be placed upon a suitable supporting surface, in stable position, without risk of being easily upset. This reservoir kmay have a threaded opening to be closed by a screw plug 2, so that the contents may be replenished. On the inside is a vertical cylinder 3, which is closed at its inner end and may rest on the bottom of the vessel 1. The opposite end projects from the top of the vessel to a slight extent and is threaded on the exterior of the vessel, so that it can be closed by a screwthreaded perforated cap 4. The mouth of the vessel has'an inward extending rim or u or more upper openings, these openings be- .5

ing indicated at 6. Within the cylinder is a piston 7 which is normally disposed between the upper and lower openings 6, and has a hollow stem 8 which is'enveloped by a thicker hollow stem 9. Both the stems 8 and 9 pass 70 through the cap or closure 4 and project above the top oi' the vessel 1; and the stem 9 is somewhat shorter than the stern 8, and at its upper end is expanded to form a bowl 10, just below the upper extremity of the 75 stem 8.

The outer stem 9 terminates at its lower end at the top face of the piston 7 and is aiiixed thereto, while the stem 8 passes through the piston 7. or more openings 11, which effects communication between the space inside thestem or conduit 9 andaround the stem 8 with the interior of the cylinder 3. On the stem 9 within the cylinder and below the cap 4 is a fixed 85' collar 13 and inside the cylinder 3 between the collar 13 and piston 7 is a iixed'collar 14 having an opening through which vthe stem 9 can pass. A coiled spring 12 encircles stem 9 with its ends abutting the collars 13 and 14. 90

This spring holds the piston 7 in partly raised position so that it will always be between-the upper and lower openings 6.

T o be iilled by this charging device the cigarette llighter which is shownV at 15, 95

Fig` 2, is opened at the-bottom by removing the plug screw which normally closes the threaded filling opening 16. The in-V side of the cigarette lighter has a wick of absorbent material 17, one end of whichlOO Within the reservoir 1 1s w' Near the piston the stem 9 has one 30 to the inside of the cigarette lighter. The

' cigarette lighter is then forced downward deressinoi the aisto'n 7. Y As the iston 7 asses b downwardly toward and past the lower opening 6 gasoline is forced up tlirou'gh'the stein 8 acting as a discharge nozzle to saturate the wick 17. When too much fluid is expelled from the stem 8 it flows back through the hole 16 into the returning means comprisingtlie bowl l0, the stem 9 and holes ll into the cylinder 3 and through the holes 6 into the flask l. After the cigarette lighter is removed the hole 16 is closed by screwingin the plug for this hole and the expansion of the spring l2 again raises the piston Z to starting position.A of the cylinder 3 is always kept The lower end full of gasoline vlo tlow through the lower openings 6, as soon as tne pressure on the bowl lO is removed so that'tlie piston 7 can be raisedv again.

The device is thus very simple in construction and easy to operate. It is certain in action andv involves no risk either of mishap nor waste ofthe fluid, because any excess fluid that is forced out of stein 8 can be intercepted and returned by the bowl i0 and stein 9, to the reservoirY l.Y f

Whereas, l have described my invention by reference to specic forms thereof, itwill .be

understood that many changes and modilications may be made with-out departing fron l the spirit of the invention.

I claim l. A filling device comprising a reservoir,

a cylinder within the reservoir projecting from the top thereof and being closed at its bottom, said cylinder having openings spaced at different distances from said bottom, a piston in the cylinder and normally between saidV openings, a hollow stein connected'to the piston and having openings therethrough adjacent to the piston, said stem projecting to the outside of the reservoir, a hollow stem within the lirst stern passing through the piston and prcjectngfrom the reservoir beyondV the end of the first stem, the outer end of the tirsl stem being expanded to form af bowl surrounding the inner stem, so that pressure on the outer stein causes a portionlof the contents ot the reservoir to be expelled through the inner stem, any excess being caught by the bowl and returned through the outer stem to the inside of the reservoi 2. A charging device comprising a reservoir, a cylinder within the reservoirand projecting through the top, the inner end o'f'saicl cylinder being closed, a perforated closure for the outer end of said cylinder, said cylinder'having one or more upper and lower openthe outer stem and stem having openings adjacent the piston, the

outer extremity of saidstem being expanded to form a bowl, a collar on the inside of the cylinder, a collar on the stem inside of the cylinder, aspring encircling the'outer stein vbetweensaid collars, said spring acting normallyrto keep the piston between the upperV and'lo'wer yopenings in the cylinder, and an inner stem secured to the piston and opening therethrough, the inner stem passing through protruding 'beyond the bowl thereof.
