nying drawings, forming part thereof.

My invention relates to apparatus for drawing acids, spirits of ammonia, chlorine water, ethers, and other corrosive and offensive iuids from the carboys in which they are delivered by the manufacturer to the retailer or user. These earboys are of such size and weight that 1 the services of two strong men are required to lift and tiltthem sufficiently to pour their contents into the desired receptacles, and, owing to their bulky shape, it is almost impossible to direct the outpouring stream accurately enough to prevent more or less waste of the fluid. Moreover, the corrosive properties of the fluids render the spattering thereof incident to such operation injurious not only to the clothing of the operators but also to their It has long been realized, therefore, by those who are obliged to handle these carboys and their contents that some means should be devised for drawing off the iiuid, which will obviate tilting the carboy, and without wasting the liquid or subjecting the clothing or person of the user to its injurions effects.

The object of my invention is to provide an acid-dispenser which will transfer the contents ofa carboy to any desired receptacle in an y de sired quantity by a steady easy-flowing stream without waste or spatter of the fluid, which cau be almost instantly applied to and detached from the earboy, which obviates the necessity of tilting the latter, and which is tritiing in cost.

To these ends my invention consists in the construction'and combination ofparts, herein- .after described, and particularly pointed out in the claims.

Referring to the drawings, in which like 1et ters designate like parts throughout, Figure l is a side elevation, partly in section, of my improved acid-dispenser, Fig. 2 is a side elevation of a earboy, showing the preferred manner of attaching the dispenser thereto for the purpose of drawing the duid therefrom.

(No model l The letter A designates the short arm, and B the long arm, of a siphonic tube, which may be made of glass or other substance not liable j to corrosion from the fluid with which it is to be used. The tube is provided, near the end of its long arm, with a valve, C, which may consist of an ordinary stop-cock, as shown, for a purpose hereinafter mentioned. From a pointlslightly above the said valve a smaller tube, D, branches out from the long arm of the main tube, extending'upwardly to an eX- haust-cylinder, H. This exhaust-cylinder has a removable cap, K, through which passes the stem of a piston, L, said piston being provided with a suitable handle at its outer end and at its inner end with any suitable packing to fill the bore of the cylinder. The packing shown consists of a collar, N, secured to the end of the piston, having a cup-shaped packing-ring, M, secured thereon bya nut, P; but such packing is common and lforms no part of my invention.

Tt will be observed that the tube D makes its connection with cylinder H through the lower end wall ofthe latter, and that the cylinder extends to or nearly to the highest point of the siphon, as clearly shown in Fig. l. These features are of great importance to the snccessful operation of the dispenser, since if tube D were connected with the cylinder through the side and above the bottom of the latter the space between the mouth of the tube and the bottom ofthe cylinder would be constantly iilled by the fluid from the cai-boy, and the corrosive properties of the iluid would soon destroy the end wall of the cylinder as well as the packing upon the end of the piston. \Vith the tube leading into the end wall of the cylinder, however, as shown by me, whatever tiuid is necessarily drawn into the cylinder in starting the siphon descends through the tube again as soon as the piston ceases its upward movement and cannot accumulate in the bottom of the cylinder. Again, 'if the cylinder did not extend substantially to the highest point of the siphon, and consequently to a point higher than the level of the fluid in the carboy, the [luid in the long arm of the siphon, when the valve at the lower end thereof is closed, would back up in the cylinder against the piston-head, and, as soon as the latter became slightly worn, would force its way past said head and out at the upper end of the oylinder. It will thus be seen that both ofV said features of construction have special relation to the destructive character of the fiuids with which the dispenser is designed to be used.

The operation of the construction thus far described is as follows: The short arm A is inserted within the open mouth of the carboy, and the desired receptacle is placed beneath the long arm B to receive the fluid, the piston being in the position shown in Fig. 1, and the valve C closed. The piston is then drawn upward within the cylinder, exhausting the air within the tube, thus creating a vacuu 1n therein between valve() and the end of arm Aimmersed in the duid. This movement is immediately followed by a column ,of the fluid which ascends arm A and descends arm B until it contacts with the. valve C, and by opening said valve the liquid will begin and continue to flow into the receptacle upon the wellknown principle of the siphon until the carboy is empty, or until cut oft' by closing valve C,

v which latter can be done as often as desired,

'the fluid commencing to flow again as soon as the valve is opened.

It will be observed that with a dispenser thus constructed the stream of escaping fluid is gentle and steady in its movement, thus avoiding all spattering, that no air-tight joints have to be constructed in applying the dispenser to the carboy, that no pressure is exerted against the inner surface of the carboy, and that having once started the flow of the duid through the tube the valve C may be utilized, like an ordinary faucet, `to stop and start the fiow as often as may be desired until the carboy is empty.

To provide for removing the tube from the carboy While more or less fluid remains therein, as when it is desired to transfer the dispenser to another carboy containing another fluid, and yet not waste Ithe fluid contained within the tube, I construct an air-inlet, E, in the middle of the bend between the two arms ofthe tube, which inlet will be kept normally closed by a stopper, F, as shown in Fig. l, or by an ordinary plug-valve, as shown in Fig. 2. By opening this inlet and permitting the air to enter the tube the column of fluid therein will be divided at that point, that portion'thereof in arm A descending into the carboy, and that in arm B descending into the receptacle, and the tube can then be removed from the carboy without dripping or waste of any kind.

The dispenser could be operated very successfully by hand; but to provide for conveniently securing it to the carboy I have shown in Fig. 2 a carboy, R, having the dispenser'secured thereto in position to draw the uid from its open mouth S by means of a bracket, T. This bracket consists of a piece of wood having a straight back and inclined face, as shown, and has projecting from top and bottom the arms V lV, the lattervhaving a clampscrew, O, passing through it, by means of'which arms and screw the bracket is adapted to be quickly and firmly secured to the carboy, as shown. The dispenser is secured. to the face `of the bracket by bands Z Z passingaronnd the bracket and cylinder H, as shown. The only object in making the face of the bracket inclinedl is to facilitate directing the stream from the tube into the desired receptacle. This re'- sult will be still further facilitated by placing the carboy upon a low platform, or otherwise elevating it slightly from the ground or floor,

and by allowing one side to project slightly beyond the edge of such platform.

I thus provide a simple and cheap acid-dis penser, which can be applied to and detached from a carboy with perfect facility, and which when so applied serves as a means for rapidly and safely drawing the most corrosive liquids therefrom in any desired quantities.

I claim-l 1 In an acid-dispenser, the combination, wlth the siph'on having the valves C and E, cylin` der .H and its piston, and tube D, connecting the lower end wall of said cylinder with the. siphon, as shown, of bracket T, 'having the straight and inclined sides, as shown, and having the arms V W extending laterally from the top and bottom of its straight side, one .of

said ,arms being provided with the clamp -screw O, and bands Z, securing the cylinder H to the inclined side of said bracket, substantially in the manner set forth.
