To all zohom itmaycoaoern Be it known that I, SmMooR S. SAGER, a
citizen of the Dominion of Canada, residing.
at Buffalo, in'the county of Erie and State of New York, have invented certain new and useful Improvements in Pumps for-Fruit- Jars and the like, of which the followingis a specification.
This invention relates to pumps for sealing fruit jars and other containers, and is a division of my allowed application Serial- No. 306,718, filed June 25, 1919. The specation is limited to the pump mechanism 1 hism.
cificjar hereinafter described for use with the herein claimed pump is claimed in the parent application, and the present appliand to combinations with the jar mecha- The; principal object of the pr esent invention is to produce a pump of simple and efficient nature for exhausting the air from a jar oro'ther container in which fruit or other material is to be stored. 7
Another object is to so construct the container and pump that the cover of the for mer may act as a valve for the latter.
Other objects will appear hereinafter. With these and incidental objects in view, the invention consists in certain novel features of construction and combinations of parts the essential elements 'ofwhich are set forth in appended claims, anda preferred form of'e'mbodimentof which is hereinafter disclosed with, reference to the drawings which accompany andform part of this specification, in whlelijfdrawings:

as to permit a pin or other sharp instrument to be inserted under the Washer 41, through both flanges and into the container proper to allow air to be admitted to the inside of the container when it is desired to remove the cover.
said apertures extend-' the base of the flanges The pump proper is constructed as follows: A tube 9.has secured to one end thereof a cupped member 10.- A washer 11 of rubber or other suitable material is remove ably secured against the inner face of the flanged portion of the cupped member 10 by a strap or band spring 12. A piston 13 of a well known type is in the tube 9 and constructed to prevent air from passing through the tube into the container, but-to permit the passage of air from the container and from the inside of the cupped member 10 to pass out, an exhaust holev being formed in the tube 9 at 14. 15 is a top which screws into the tube 9 and having an the passage of the pi'stonrod 16.
aperture for I The operation of the above described devices is as follows: The container-is filled with the desired material, the washer 6 is placed between the flanges-2 and 3, and the cover is put in place inside the flange 2. The pump proper is now applied to the container withthe washer 11 seated snugly against the upper outer edge of the container body. \The' piston 13 is now operated by the rod 16, and as the piston moves up in the tube 9, the suction *auses the, coverto-be raised enough. to[perm1tthe escape of air from the, container until the pressure-i'sequalized' on both sides'of'the covenfl. On the down stroke of the piston, the cover 4 is drawn down against the washer 6 by the rarefied condition of the air within the container, thus preventing the replacement oftheair exhausted from within the container. The- "p'ump is operated asmany times as. is desired or required, and is then removed. The
container is thereby sealed and may now be stored away.
While the form of mechanisimhere shown' and described is admirably adapted to fulfil the objects primarily stated,it is to be understood-that it is not intended to confinethe invention to the one form of embodiment herein disclosed for it is susceptible of embodiment in various forms all coming Within the scope of the claims which follow.
What I claim and desire to secure by Let "ters Patent is:
' 1 A pump comprising a cylinder, at piston working in said cylinder, 21 cupped ele- 10 a resilient seated in said element, securing said resilient ment secured to said cylinder, washer removably and a spring for washer in place;
