APPARATUS FOR SEALING PRESERVING-JARS.

Application filed July 24,

To all whom it may concern Be it known that I, ARTHUR EGGL'ETON \Vonsrnn, a subject of the King of Great Britain, and a resident of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Apparatus for Sealing Preserving-Jars, of which the following is a specification.

My invention relates to improvements in apparatus for sealing preserving jars, such as those containing fruit, meat, milk or any perishable article and the object of my invention is to provide an apparatus by the use of which such are, after filling, may be exhausted of air and then sealed tightly, which apparatus is simple in construction and operation and capable of being manufactured and sold at a low cost.

I attain this object by the construction illustrated in the accompanying drawing in which the figure shows a front view of the device, with the side removed.

The apparatus consists of a box 1 divided into upper and lower compartments 2 and 3, one side of the lower compartment being provided with a door (not shown) capable of being opened and closed in the usual manner, this compartment being air tight when the door is closed. On one wall in the inside of the box is a hook 4: on which are hung a number of spring clips 5 of dif ferent sizes and each of which is adapted to be detachably mounted horizontally of the box by inserting it in a clip member 6 secured to the compartment wall so as to grip a jar or bottle placed in it, as shown, the bottle then resting on the bottom of the compartment, as in the case of a milk bottle, or on supporting blocks 7 and 8 which are used for bottles or jars of less height, the thickness of the blocks provided varying according to the height of the jars to be supported, being, however, such as will support the jar so that its cap will be in. close proximity to the nozzle hereinafter described.

In the compartment 3 is rotatably mounted a crank shaft 9 the operation of which by a handle 10 or any other suitable means operates air suction pumps 11 and 12 the suction pipes 13 and 141 of which are con Specification of Letters Patent.

1919. Serial No. 313,037.

nected to a transverse pipe 15 which forms a branch of a vertical pipe 16 the lower end of which extends into the compartment 2 as a nozzle 17 directly above the center of the jar cover 18 while its opposite end extends upwardly through the top of compartment 3 and is provided with a suitable valve 19 by the operation of which the pipe 16 may be opened or closed to or from the atmosphere. Air holes or vents 20 are formed in a wall of the compartment 3 to permit escape of the air drawn thereinto from the lower compartment by the pumps 11 and 12.

The manner in which the apparatus is operated and its utility will be readily seen and may be described briefly as follows The bottle or jar containing the articles to be preserved is placed in the lower compartment 2 with the cap on being rested on the bottom of the compartment, or on the blocks 7 and 8, as may be required, and the door is then closed. The pumps are then set in operation, the valve-19 being first of all closed, whereupon all the air in compartment 2 and in the jar will be drawn out into com mrtment 3, creating a vacuum in compartment 2. The valve 19 is then opened so that the air rushes into the pipe 16 and out through the nozzle into compartment 2, striking the bottle cap in the center and driving it down into place so that the bottle becomes tightly and perfectly sealed. 1

From the foregoing it will be seen that I have devised a practical and effective apparatus for sealing jars in a simple and convenient manner.

What I claim as my invention is An apparatus for sealing preserving jars comprising an air tight compartment adapted to inclose a jar and its cap, a vertical air duct having its lower end extending into said compartment and its outer end closed by a valve, said air duct being provided intermediate its ends with a lateral extension and pumping mechanism for creating a vacuum in said extension to exhaust the air within the compartment.

Dated at Vancouver, B. (1., this 25th day of June, 1919.
