f lAPF'Ai-iA'l-'u's FOR DlslNFEoNTlNG AND DEoDoRlzlNG PURPOSES.

SPECIFICATION forming-'part of Letters Patent No. 591,352, dated october 5, 1897. Application filed July 10, 1896. Serial No. 598,699. (No model.)

' To all whom it may ooncerm' 4 Beit known that I, ALEXANDER G. HUN- TER, a subject of the Queen of Great Britain, anda resident of Toronto Junctionpin the county of York and Province of Ontario, Oanada, have invented certain new and useful Improvements in Apparatus for Disinfe'cting and Deodorizing Purposes, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of `my invention is to produce a simple and effective apparatus for disinfecting and deodorizing purposes and which can be readily constructed and easily manipulated; and the invention consists in the peculiar construction and operationof the in-V vention, as hereinafter more fully described, and pointed out in the claims. i

Referring to the accompanying drawings, Figure 1 represents a vertical longitudinal section of an apparatus for disinfectin g and deodorizing embodying my invention. Fig. 2 is a plan or top view of the same, Fig. 3 is an enlarged view of the driving-gear.

1 represents a tank or reservoir to receive the fluids and other material to be used for disinfecting purposes, and is open at the top, so that said materials may be inserted `therein, which opening is covered by a lid 2, attached to a table A, supported in any suitable manner. 4-is a cylinder connected near its bottom to the bottom of the tank 1 by a pipe 3. A branch pipe 5 extends up from the pipe 3 and is connected to the top of the cylinder 4 by a pipe 5fL and to the-center of the cylinder by a pipe 5b. Each of the pipes 3, 5a, and 5b is tted with a check-valve 31.

6 is a rod that passes through the 'cylinder 4 and is fitted at its upper end with, abevelwheel 8. The portion of this rod that is "within the cylinder is formed with a right and leftV screw-thread which meet in the center of the cylinder.V Upon the screw-threaded portions are fitted pistons7 7, having corresponding screw-threaded holes. Said pistons are held in the cylinder so that they cannot turn, but must work up or down as the shaft 6 is rotated. In the drawings I have shown a rod 34 passing through said pistons and secured at its ends to the heads of the cylinder.

To the side of the cylinder opposite to the pipes 3 5a 5b are secured pipes 25, 26, and 27, each fitted with a check-valve 30, that connect with an upright pipe 28, on the upper end of which is fitted an air-chamber 35, and from said pipe 28 is a brauch pipe 28u, to which a hose may be attached. Said pipe 28L is fitted with a suitable stop cock or valve.

To the table A are secured two standards a a, in which is mounted a shaft 11, upon which is loosely mounted twopinions 9 and 10 in gear with the bevel-wheel 8.- A clutchgear is also mounted on said shaft between 4the'pinions, so that either of said pinions 9 or 10 can be held fast to the shaft 11, so as to operatejthe cog-wheel 8 when said shaft 11 is rotated by the crank 12, to which a handle 13 'is attached.

` To operate the clutch-gear, I secure to the shaft 6, just above the table A, a cog-wheel 24, in gearwith an intermediate wheel 23, carried by a stud, which wheel is in gear with a Wheel 22, having a central screw-threaded hole through which passes the screw-threaded end of a rod 2l, the upper end of which has avwedge-shaped projection on each side that comes into contact with the inner sides of a fork 19, fulcrurned to a rod 20, so that as the screw-threaded rod 21 is worked up and down it will throw the fork 19 first to one side and then to the other side, th us shifting the clutch and causingthe pinions 9 and 10 to be thrown alternately into gear with the cog-wheel 8,thus reversing the motion of the shaft 6 to draw the pistons 7 up or down and that automatically and without reversing the motion of the crank 12. On the shaft 6, just under the table A, is also secured a sprocket-wheel b, that by a chain o communicates motion to a sprocket-wheel CZ on a shaft e of an agitator located in the tank 1. I have shown the chain o passing through small vopenings in thel upper portion of the tank, but of course it could be arranged so that the chain c would pass v IOS say lO-transmits motion to the bevel-wheel 8 and shaft 6, and as the pistons 7cannot turn in the cylinder-i they are forced apart, creating a vacuum between them, by which liquid from the tank l is drawn in through pipe 5b. At the same time the rod 2l has been gradually lowered until the cam on one side strikes the arm 19 and thus throws the clutch over, so that the pinion t) is in gear with the bevelwheel S, which causes it to rotate in the opposite direction, thus moving the pistons again toward each other and drawing liquid from the tank l through pipes 5 and 3a into the upper and lower portions of the cylinder 4., at the same time forcing the liquid between the pistons out through the pipe 25 into the pipe 2S, from which it is discharged. lVhen the pistons are again forced apart, the liquid in the upper and lower portions of the cylinder is forced out through the pipes 26 and 27 into the pipe 28 to be delivered. The rod 2l being carried up forces the fork over to the otherside, and thus the operation is repeated. Of course as the shaft Gis rotated the agitator in the tank l will be rotated first one way and then the other, thus keeping the ingredients inv the same thoroughly mixed.

lVhat I claim isl.
