VACUUMIZERV Application-filed December 18, 1923. Serial No. 681,326.

This invention relates to improvements in vacuumizers and is primarily designed for use in sealing cans, jars and the like ordinarily usedin preserving, it being well recognizedthat the keeping quality of the contents of any vessel are much improved through the creation of at least a partial vacuum .within the container.

Another object of the invention resides in the provision of a device so designed that one or more jars may be sealed simultaneously and with but a single operation of the device.

As a further object the invention contemplates the provision of an improved packing between the moving elements which will elfectively prevent the escape of air between the moving parts thereby insuring maximum efliciency. v

l/Vith these and other objects in view which will become more apparent as the description proceeds the invention consists in the. novel construction, combination and arrangement of parts which will be fully set forth in the following specification, claimed and illustrated in the accompanying drawing, in which Figure 1 is a top plan view partially in section of this improved vacuumizer showing the 1 same constructed for household use.

Figure 2 is a side View of Figure 1 showing portions broken away to clearly illustrate the details of construction;

Figure 3 is a fragmentary enlarged sectional view illustrating the packing in detail.

Figure 4 is an enlarged fragmentary view of a portion of the device illustrating a modified form of valve.

Figure 5 is a View similar to Figure 2 of a modified form ofvacuumizer showing the tion thereto to provide the inner and outer chambers 14 and 15 respectively. The wall 13 is provide-cl with an opening 16 and a simi-' lar opening 17 is formed in the wall 12' for-a purpose to be more fully hereinafter described.

Secured to the wall 13 above the opening 16 is a strip 18 which retains a flap valve 19 in place on the wall 13 where it willact to close the opening 16. A similar strip 20 retaining the flap valve 21 in place over the opening 17 is secured to the wall-12 and thus it will be seenthat the flow of airthrough the openings is checked in one direction. V 1

' (lo-operating with the body 10 is the head designated generically by the numeral 22 V A handle '25 is secured to the upper are flanges 26 serving as a base or support for the packing rings 27 and 28which are ar: ranged so that their bightportions abut and are secured in place by a retaining ring 29. In order to yieldably hold the packing. rings 27 and 28 in proper position I also provide the inner and outer bands 30 and 31 respectively;

of a relatively soft compressible material such as rubber. are substantially triangular 1n cross section.

In the modified form of valve illustrated in Figure 4 the opening 32 is perfectlytaperedto receive the cone shaped portion 33 of a flapv valve 34 which is hinged as-at 35 to the wall H of its respective chamber.

In the modified form .of the device illusno trated in Figure 5 the body designated generically by the numeral 36 comprises a bottom 37 which is secured at its edge within an annular wall 38. This bottom is provided with an opening 39 which is normally covered by a flap valve40 which is retained in place by means of a strip 41; Arranged to fit within the body 36 is the .head member designated generically by the numeral 42 which com prises acontainer consisting of. the sid'e'an'd bottom-Walls 43 and44 respectively and a As shown these rings '30'and' 31 contained within the head. movement of the head it will be obvious that removable cover which is retained in place by means of clamps 46 and rendered airtight through the use of a gasket 47 interposed between the cover and the upper edge of the Wall 43.

Like the bottom wall of the body 36 the bottom wall 44 of the container is provided with an opening 48 which is covered by a flap or check valve 49 secured in place by means of a strip 50.

As illustrated in Figure 6 the wall 44 is extended beyond the outer face of the wall 43 to provide a flange 51 for supporting the packing ring 52. A retaining. ring 53 is secured to the device in such a position as to firmly clamp the packing ring in place.

In the operation of the structure illustrated in Figures 1, 2 and 3 the preserving jar designated by the numeral 54 is seated on the bottom 11 within the chamber 14. The head 22 isthen pressed downwardlv thus causing the air contained within the chambers 13 and 1.4 to be exhausted and displaced with the air a of the contents against spoilage.

The operation of the device illustrated in Figure 5 is essentially that previouslydescribed with the exception that the jars are placed within the head 42 and the cover 45 is 'removably attached for the purpose of rendering access to the interiorot the head member easy.
