SALT-SHAKER.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application filed April 26, 1910. Serial No. 557,702.

To all whom it may concern:

Be it known that I, TVILLIAM H. VANCE, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in SaltShakers, of which the following is a specification.

My invention relates to a device which is especially designed for the sifting or sprinklin of salt or other kindred material in desired quantities.

It consists in the novel construction of the container, with means whereby the salt is prevented from attracting moisture which prevents its being discharged.

It also comprises details of construction which will be more fully explained by refer ence to the accompanying drawing, in which the figure is a vertical section of my shaker.

Great difiiculty is experienced in maintaining salt in the proper condition to be used in a salt shaker by reason of its tend-. ency to attract moisture to such an extent that it cannot be readily shaken through the small holes of the sifter.

It is the object of my invention to preserve the salt in so dry a condition that it can be readily discharged from the shaker without the above described difliculty.

My shaker consists of an exterior chamber A, and an interior salt container 2; these two being so united that the inner one may be hermetically closed against the entrance of air when not in use, and protected by be ing surrounded by a body of dry air contained within the outer chamber. This outer chamber may be of any suitable or desired ornamental shape, and I have shown it having a screw cap or cover 3 with a flange 3 to hold the packing in place around the inner chamber. The material may be of metal or glass, and the bottom 4 may also be made separable, if desired, so as to allow the inner chamber to be inserted from the bottom.

The outer chamber A. has an inwardly projecting annular flange, as shown at 5, and the inner chamber 2 has a corresponding projecting flange 6 which fits into the body of the chamber A below the flange 5.

The upper portion of the body 2 has small holes or perforations 7 on the side for the escape of the salt when desired, and it has also a screw cap or cover, as shown at 8, whereby it can be refilled. \Vhen in ordinary closed condition, as shown in the figure, the perforations 7 will lie within the upper portion of the chamber A, and above the flange 5. This space above the flange 5 may be filled with a fibrous packing 9 so that when the upper portion is closed, as described, the perforations 7 will be covered by this fibrous packing which will prevent the entrance of air at this point.

Below the flange, 5, the interior of the chamber, A, is larger than the body, 2, and will be filled with a body of air, which is the non-conductor and which forms substantially an air-tight joint which will prevent the absorption of atmospheric moisture by the salt within the inner receptacle.

When saltis to be used, it is only necessary to extend the chamber 2 by pulling it up until the flange 6 contacts with the flange 5, when the perforations 7 will be exposed above the top 3, and salt can be shaken or sifted out to any desired extent.

This construction enables me to preserve the salt at all times in perfectly dry condition, and no trouble is experienced in sifting the salt out of the shaker at any time.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. The combination in a salt shaker, of an exterior receptacle, an interior salt-containing receptacle of smaller diameter and having discharge perforations near the top, said interior receptacle being slidable within the outer one to expose or conceal the perforations, and said outer receptacle having a packed air-tight joint through which the perforated end of the inner receptacle operates and by which the perforations are normally closed, a flange on the inner wall of the exterior receptacle and a flange on the outer wall of the interior receptacle adapted to contact-with the first-named flange and thereby limit the outward movement of the interiorreceptacle, said first named flange serving, also, as a seat for said packing.

2. The combination in a salt shaker, of an inner chamber having perforations near the top, and a projecting flange or stop upon its body, an outer chamber of larger diameter having a corresponding flange or stop projecting inwardly, and a cap through which I my hand in the presence of two subscribing the inner chamber is slidable to expose or Witnesses.

conceal the perforations and a packin fitting between the cap an flange of the Enter WILLIAM VANCE 5 chamber, and forming a closure for the per- Vitncsses:

forations. RAYMOND A. LEONARD,

In testimony whereof I have hereunto set CHARLES EDELMAN.
