To a whom it may concern:

Be'it known that I, CHARLES CORNWELL HovEY, a citizen'of the United States, residing at Bainbridge, in the county of Ohenango 5 and State of New York, have invented an Im-- 1 provement in Apparatus for Sealing Cans, ,Jars, and other Packa es by Atmospheric Pressure, of which the ollowing is a specification.

have shown and described a machine for receiving the cans, jars, &c., and in which the vacuum is established for sealing the covers and which machine is similar to the one shown and described herein.

In carrying out my resent invention Iemploy a machine includ mg the cans, jars, &c.', and in which the covers are'sealed by atmospheric pressure, a vacuum-tank, anair-pump, a pipe fromfsaid' machine to the air-pump and in which is located a three-way valve, a pipe from the vacuumtank to the aforesaid plpe and joined there with between-the three-way valve and the air-pump, and a two-wayvalve in the said 1 e. lhe details of the unitary apparatus and the operation ofthe same are hereinafter described. 3

In the drawing I have represented the uni- ..tary deviceof my improvement by an elevationin which the cover of the rece tacle is shown as open, so'as to disclose the parts therein. c n

The ,machine, illustrated for receiving the cans, jars, &., and in which the vacuum is established for sealing the covers and which is sim trt'o the oneshown and described in myapplication hereinbefore noted, comprises a standard a, shownas hollow, a recep tacle b, comprisin a top,.bottom,,sidesand back, and a cover shown in a horizontal p0 sition, but adapted to set up into a vertical position to close the receptacle. The platform 0 shown within the receptacle ,isad'apted-to receive the cans, 'ars, &c. the covers of which are to beseale by atmospheric pressure: cover isconnected to a rod cflwhi'ch.

' My invention relates to a unitary apparaby me March 6, 1905, Serial No. 248,390, I

mg a receptacle receiv-' passes down through the bottom of the recep- I tacle and through the standard and is conneoted to one end of a foot-lever c, by which the said platform and the articles thereon are adapted to be raised. (Z re resents a laten also in said receptacle an connecte to a screw-rod d, which passes up through a stuffing-boX in the cover of the receptacle and through a brace-bar d terminating in a hand-; wheel by which the screw is rotated andthe platen d raised and lowered.

6 represents a gage connected upon theto p of the receptacle with the inside, so as to indicate the vacuum piesent.

f is a vacuum tank or cylinder suitably sup ported, and 9 an air-pump, which latter may e of any well-known or desired construction. h is a pipe connected to the top of the receptacle b and internally communicating with the receptacle and extending to the air-pump In the line of this pipe it there is a three-way valve 11, which in one position closes off the. pipe h, in another position opens up the' pipe h, and in another position closes the communicati'on-from the receptacle 6 to the air-pum and opens a connection from the receptac'l for the entrance of the atmosphere.

dc is a pipe from the vacuum-tank, to the pipe h, connecting with the pipe h etweenv the three-way .valve-i and the air-pump, and in this line of pipe is a two-way valve '1, which in one position opens up communication through the pipe 7c and in anotherposition closes off the same. I r In the method employed, or, inother words, in the operation of the apparatus described, the air-pump g is being run, the

valve Z open, so that the pum 1s exhausting the vacuum-tank While 't 's is proceeding the cans,-jars, or other packages the Govers of which are to be sealed byatrnospheric'j pressure are placed upon the platforms and short distance-say one-fourth or, threethe receptacle is now closed and secured,

valve 1', is closed in the line of pipelaand the a the platen d screwed down until withinf'a in the receptacle a partial vacuum. The valve Z is then closed and the pump allowed to Work through the pipe h, exhausting the air only from the receptacle containing the cans, jars, &c,, until t 1e desired vacuum is obtained. At this moment foot-pressure is applied to the lever c, the rod 0 is elevated, raising the platform 0 and bringing the covers with force against the under side of the ro platen d, and this footressure is mainmunication through said valve for the atmosphere to pass by the pi e it into the recep tacle and effectually sea the covers. After the admission of air to the receptacle, which has the effect of balancing the pressure within the receptacle with that of the atmosphere, the platform 0 is to be lowered, so as to' free the covers of the cans, jars, or other packa es of contact with the platen d. The cover is now let down, so as to open up the receptacle for the removal of the cans, jars,

, or other packages the covers of which have been sealed by atmospheric pressure. While the cans, jars, &c., are being removed from .35 the receptacle and others placed therein the covers of which are to be sealed the-yalve Z "is opened, so that the pump can work to exhaust the air from the vacuum-tank f. 1

The operation or method herein described 40 of sealing the covers of cans, jars, &c is successively repeated. v

I claim as my invention 1 1. The combination with a receptacle adapted to receive the cans, jars, &c., the

covers of which are to be sealed by atmospheric pressure, of a vacuum-tank, an airpum a pipe extending from the air-pump to t e receptacle, a branch pipe from the vacuum-tank to said pipe and valves in said pipes by which a partialvacuum is first established in the receptacle and then as complete a vacuum as desired and by which thereafter the pressure in the machine and vacuum-tank may be equalized for the bene- 5 5 fit of the tank and air be then admitted to the receptacle so that the same may be opened and the jars, cans, &'c., with their sealed covers removed and replaced by others to be sealed.

6o 2. The combination with a receptacle adapted to receive the cans, jars, &c., the covers of which are to be sealed by atmospheric pressure, of a vacuum-tank, an air- V pump, a pipe extending from the receptacle .ceptacle first and the pum covers of which are to be sealed by atmos- 'vices connected to the receptacle for admitto the airump, athree-wa'y valve in the line of sai ,pipe, a ipe from the vacuum tank tothe aforesai "pipe connected therewith between the air-pump and -said threeway valve, and a two-way valve in the lineof said pipe.

3. A unitary apparatus forsealing the covers of cans, jars or other packages by atmospheric pressure, comprising a receptacle recelving said cans, jars, &c., and adapted to be closed air-tight, devices connected with .75 said receptacle for pressing the covers of said cans, jars, &c.,. to'their seats and holding them temporarily under pressure, an adjacent vacuum-tank, an adjacent air-pump, a pipe from said rece tacle to said air-pumi'p by which the air may e exhausteddirectly om said receptacle, and a three-way valvethe line of'said pipe, a pipe from the vacuumtank to the aforesaid pipe joining therewith between the air-pump and said three-way valve and a two-way valve in the line of said pipe, substantially as set fort/h.

4. The combination with a ieceptacle adapted to receive the cans, jars, &c., the covers of which are to be sealed by atmoso pheric pressure; of a vacuum-tank, an airpump, communicatingpassageways between the pump and receptacle and the tank, pump, and receptacle, and devices for controlling the said passage-ways, whereby the tank may be caused to exhaust from the re- I thereafter exhaust from the receptacle prior to the sealing of the covers and after the sealing an equilibrium be established between the recep- I00 tacle and tank prior to admitting the air to the receptacle.

5. The combination with a receptacle adapted to receive the cans, jars, &c., the covers of which are to be sealed by atmospheric pressure, of a vacuum-tank, an airpump, communicating passage ways between the dpump and receptacle and the tank, pump, an receptacle, devices for controlling the said passage-ways, whereby the tank may be caused to exhaust from the receptacle first, and the pump thereafter exhaustfrom the receptacle prior to the sealing of the covers and after the sealing an equilibrium be established between the receptacle and tank :15 prior to admitting the air to the receptacle and also whereby the pump may act. directly upon the tank to create a vacuum therein.

6'. The combination with a receptacle adapted to receive the cans, jars,- &c., the

pheric pressure and devices for forcing the covers of said jars,.cans, or other packages to their seats and holding them closed and de- 12 5 ting the atmosphere to seal the covers rior to opening the same, of a vacuum-tan an air-pump, communicating passage-waysbetaele and tank prior to admitting the air to the reee' tacle. m
