I DEVICE FOR CLOSING PRESERVE JARS.

Application filed Aiigu'st 19, 1924. Serial No. 732,983.

To all whom it may concern:

Be it known that I, OTTOMAR Vorcr, a citizen of the German Republic, and residing at Dusseldorf, Germany, have invented certain new and useful Improvements in Devices for Closing Preserve Jars, of which the followin is a specification.

My inventlon relates to a device for closing preserve jars, pots or cans or the like by means of an accessory receiver and an air-pum connected therewith.

The 0 ject of my invention is advantageously distinguished from existing devices of this kind by a double valve in which the inlet and delivery valves of the receiver are combined with the inlet and delivery valves of the airpump, which latter are arranged apart and outside the pump, in such a manner that the two valves which are loosely connected with each other can be simply lifted at the same time thus allowing the atmospheric air to rush into the receiver, after having served as inlet and delivery valves for the air pump until sufficient rarefaction of the air in the receiver has been obtained.

In order that the invention be more clearly understood an example embodying the same has been shown in the accompanying drawing in which Fig. 1, is an elevation of the object of my invention in longitudinal section, and

Fig. 2, is a view of a modified arrangement partly in section.

On the lid a which is loosely set upon the accessory receiver 6, the cylinder 0 of the air pump is fixed, in which by means of the rod d and the handle 0 the piston f can be moved up and down. By means of the conduit g the air pump is in firm and air tight connection with the housing h on the lid. The lid a is bored through in the longitudinal axis of the housing, thus forming on the bottom of the latter the contact surface e handle m is attached.

receiver and the lid, and q is the preserve jar or can that is to be closed.

The device works as follows:

The preserve jar, filled and provided with packing ring and lid, is placed into the accessory receiver I). Then the lid a with the pump and its valves are fitted on the packing ring of the receiver. The piston of the pump is moved up and down. When the piston goes down, the valve 70 is opened and the air from the receiver enters into the cylinder. 0 of the pump. At the same time the valve n is closed by the suction of the pump. When the piston is moved upwards the valve is is closed, whereas the valve 02 opens giving exit to the air. When a greater resistance against thedownward motion of the piston shows that the air in the receiver is sufficiently rarefied, both valves is and n are simultaneously lifted with a jerk by means of thehandle m, thus allowing the atmospheric air to rush in suddenly and to close the preserve jar or can. It will appear that the valveslc and nare first used as a means for working the air pump and then quite independent of the pump as a means to fill the receiver with air.

The device represented in Fig. 2 is worked in the same way, the bell shaped receiver 1) being placed upon the packing ring p and covering up the preserve jar on the bottom plate a.

l/Vhile in describing the invention reference has been made to a particular example embodying the same I wish it to be understood that my invention is not limited to the construction shown in the drawing, and that various changes may be made in the general arrangement of the apparatus and the construction of its parts without departing from the invention.

I claim:

1. In a device for closing preserve jars, cans, and the like, an ,accessoryrecciver, an air pump connected thereto by a passage for rarefying the air contained in the receiver, and nlet and outlet valves for the pump arranged outside the same and in the connecting passage with the receiver, both of said valves adapted to be actuated to open the receiver to the atmosphere.

2. In .adevice for closing preserve jars, cans and the like, a receiver, an air pump connected thereto by a passage for rarefying the air contained in the receiver, plural valves arranged in the connecting passage between the receiver and pump and serving as inlet and outlet valves for the pump, and means for substantially simultaneously opening both valves to open the. receiver to the atmosphere.

3. In a device for closing preserve jars or cans or the like, an accessory receiver, an air pump rarefying the air contained in the receiver, a lid with a housing on the accessory receiver having a port leading to the atmosphere and a port communicating with the receiver, two valves one above the other in the housing, one valve closing the receiver port againstopening inwardly and the other valve closin the atmosphere port and opening outwar y, by a chain connecting the two valves for pulling and drawing, a pipe branching ofi from the housing between'the valves and ending in the upper part of the pump.

4. In a device for closing preserve jars or cans or the like, an accessory receiver, a lid therefor, an air pump on the lid for rarefying the air contained in the receiver, a housing on the lid having an inlet port leading from the receiver and an outlet port leadin to the atmosphere, outwardly opening va ves in the housing ports, a handle attached to the outer valve for lifting by hand, a chain for pulling or drawing connecting the valves with each other, apipe branching off from the housing between the two valves and ending in the upper part of the cylinder of the air pump.

In testimony whereof I aflix my signature.
