LIQUID RECEPTACLE ANID EJECTING DEVICE.

Specification of Letters Patent.

Patented Sept 3, 1918.

Application filed May 15, 1917. Serial No. 168,655.

To all whom it may concern:

Be it known that I. llIILLAIn) E. Burxsnn, a citizen of the l'nited States. and a resi; dent of York, in the county of York and. State of Pennsylvania, have invented all new and useful Improvement in Liquid Receptacles and Ejecting Devices, of which the following is a specification.

My invention relates to improvements in liquid receptacles and ejecting devices and it consists in the combinations, constructions and arrangements herein described and claimed.

An object ofmy invention is to provide a liquid receptacle having means for either automatically or manually ejecting the liquid.

A further object of my invention is to provide a receptacle which may be entirely filled with liquid but which is provided with a spring designed to move a piston in such a manner that one-half of the liquid may be ejected and the other half may be ejected subsequently upon the retraction of the spring by manual means.

A further object of my invention is to provide a device of the type described in which the automatic ejection may be controlled'at any point in this movement manually.

Otherobjects and advantages will appear in the following specification and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a side View of one embodiment of my invention, certain parts being shown in section,

My invention may be applied to various uses such as that of a fire extinguisher, or

means for ejecting disinfectants or insecti cides, etc.

In Fig. 1 I have shown a receptacle which may be used for a number of different purposes. This receptacle consists of a cylindrical casing l which is provided atits top with a hemispherical cap 2 and at the bottom with a screw cap 3. Disposed within the casing 1 is-a plunger t which has openings 5 therethrough. This plunger has a central hub portion (5 which-is threaded on the end of a sleeve 7. The hub portion 6 is hollow. It contains a screw head 8 which is normally pressed upon by a spring 9. The opposite end of the screw is threaded into the stem of a valve 10 which slides in an auxiliaryportion of the piston 4.

The sleeve 7 is provided with guide lugs 7 which enter slots 8 in an exterior cylinder 8, see Fig. 7, which is threaded at its upper end into the cover portion 2. This permits the sleeve 7 to move longitudinally with respect to the cylinder 8 The upper end of the sleeve 7 is enlarged and is pro-' vided on its interior with threads 11. This constitutes a nut for a screw shaft 12. The latter has a collar 13 and is provided with a. bearing 14 in a recess in the cap 2. At the end of the screw shaft is a nut 15 which serves the double function of clamping the hand wheel 16 and also drawing up the shaft so that the collar 13 will be frictionally engaged and thus lock the shaft thereby preventing rotation.

Disposed within the casing 1 is a spiral spring 17 which bears at one end on the piston 4: and at the other end on a shoulder ormed by thersp or cover 2. At the lower end of the dev ce is a valve 18 whose stem is threaded into a plunger 19 which is movable in guides 20. A spring 21 normally presses on the plunger 19 so as to keep the valve 18 closed. A nozzle 22 is provided which is screwedinto the threaded extension 23.

From the foregoing description of the various parts of the device the operation thereof may be readily understood.

The device is filled through the opening normally closed by the screw plug 24. The latter has an air openin 25 for permitting air to enter as the liquid is ejected. Let us assume that the device is filled with liquid both in the upper and lower portions and that the spring has been compressed to the extent shown in Fig. l-. In this figure the collar 13 shown in close engagement with its seat, this seat being the end of the exterior cylinder 8.- The screw shaft 12 is therefore -prevented from turnin The spring 17 is, however. under compression.

Now if it is desired to eject. the liquid siiddcnly as, for instance. where .the device is used as a tire eXtinguisher. all that is necessary is to loosen the nut. 15, whereupon the spring will force the piston l downwardly. The engagement of the screw head 8 with the end of the screw shaft, 12

keeps the valve 10 open but when the piston moves downwardly the spring 9 tends to cause the closing of the valve as shown in Fig. 2, since the head has moved away froththe screw shaft 12. The sleeve 7 is pushed downwardly by the movement of the piston 1t but does not rotate because it is feathered to the exterior cylinder 8 as already e):- plained. The movement of the sleeve. however, causes the rotation of the shaft 12 and of the hand-wheel 16 which is carried by it. This is facilitated by the provision of the bearings 1%. The liquid from the lower part of the chamber forces open the check valve 18 and passes through the nozzle 22. The valve 10 closes the openings 5 and. prc vents the liquid in the upper part of the receptacle from-escaping. "lhe'valve 18 will nothopen by the weight o'f the liquid alone. but it will open when the pressure of the spring 7 is broughtinto play or when manual force is used as hereinafter described.

The movement of the piston ,4 downwardly may he stopped at any point by catching hold ,of the hand wheel 16 and then ti'ghtenlng up on the nut 1,5. Thus when a fire has been extinguished the stopping of the automatic ejecting means will; of course .save some of the extinguishing fluid.

When the piston has reached the hottom.

and the liquid in the lower part has been ejected the piston may he returned to its' original position and the spring 17 compressed by manipulation of the hand wheel 16. -The shaft'12 then acts to pull on the threaded portion 11 of the sleeve 7 to which the piston is attached. The valve'lO remains closed until the screw head 8 engages the end of the screw shaft 12 when the valve will open and letthe-liquid in the upper portion of the receptacle flow through the openi in'gs 5 into the lower portion. The liquid in the lower portion may now be expelled in precisely the same manner as that alreadv described. 0

When the nut 15 is loosened it will of course be possible to assist the spring 1? by turning the hand wheel in the direction in It will bc seen that l have provided a device in which an automatic movement is ctfected when thc nut 15 is once loosened and that this automatic movement results in the ejection of one-half of the'liquid, the other half being capable of being ejected by either a subsequent automatic nuwcment or by a manual n'iovement'.
