FLEXIBLE TOP FOR sAL'r-cELLARs.

Specification of Letters Patent.-

Patented May 28, 1907.

Applioati on filed September 16, 1906. Serial No. 384,717.

To all whom it may concern: Be it known that I, FRED BAaTLETT, a subect of the King of England, residing at Chatam,'in the Province of Ontario and Do-' formed of flexible material and can be readily manipulated to detach any salt or other powdered material which'may stick thereto or 010 the perforations thereof. Wit the foregoing, and other objects in view, which will appear as the description roceeds, the invention resides in the combination and arrangement of parts, and'in the details of. construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed may be made within the scope of the followin claims without departin fromthe spirit 0 the invention or sacrificmg any of its advantages.

In the accompanying drawings forming part of this specification :-Figure 1 is a vertical section throu h a salt cellar constructed in accordance wit the invention. Figs. '2,

. '3 and 4 illustrate modified constructions.

in the different generally prefer to construct the body portion A of glass, china, or the'like, still, in some instances, I may form only the neck portion 1 of glass or other inflexible material, the body ortion 2 in such cases bein formed of rub er or other flexible materia secured in any sui a le manner to the inflexible neck 1. Whenever the salt or other material becomes caked the flexible portion 2 of the receptacle A can be squeezed or com-v pressed to break the salt.

The essence of my 1nvent1on resldes 1n the up the lump formation of use of a top or cover B which is constructed of flexible material such for example as rubber. The upper end 3 of the flexible cover B is formed with the perforations 4 through which the salt is discharged when the shaker is, prpiperly manipulated. The top B is forme with a flexible depending annular flange 5 adapted to fit around the upper end of the body portion A.

In order to cause the cover B to be per-- manently secured in position upon receptacle A, I interpose suitable gripping means between the top or cover and the receptacle. The gripping means illustrated in Fig. 1 consists of an integral rubber bead 6 which is formed on the interior of the depending flange 5 and is adapted to fit into the semicircular groove 7 formed in the neck portion of the receptacle A. It will be apparent that the cover B can be readily removed or replaced by drawing the bead 6 out of the groove 7 or by inserting the same therein, the up er edge-of the receptacle neck being beveled as shown at 8 so as to facilitate the operation of inserting the cover, it bein understood that the lower edge of the bea or flange 5 will engage the beveled portion 8 and slide outward thereon when the cover is pushed down, whereby the flange 5 will be extended so as to permit the bead 6 to slip into the groove 7. The groove 7 preferably is wider than the bead 6 soas to provide an annular space 9 inwhich the finger or an instrument maybe fitted in .the act of withdrawing the cover. The u per portion of the cover B is domed slighiiiy as shown, so that when the cover is in lace the periphery of the domed portion of th the beveled edge 8 at the upper end of the neck 1 as shown. I

From the foregoin it will be ap arent that by constructing t e entire cover 0 flexible material, I am enabled to provide the e cover rests upon "as described. Whenever theperforations 4 become clogged with salt, it is only necessary to tap the exible cover with the finger so as to press the same downward and thus expel the salt. v

In the modified construction illustrated in F g. 3, the neck 1 of the receptacle A is rov1 ed with a supplemental ring 10 w 'ch preferably is screwed on the ordinary threads 11 at the neck of the receptacle A, the ring 10 being formed with an annular groove 12 which is engaged by the bead 6 of the annular structed for use with a metallic cover, it

being only necessary to remove the metallic cover and replace the same by the ring 10, after which a flexible cover can be used. In this construction the flexible cover can be removed in two ways if desired: first, by drawing it off the annular ring 10; and second, by permitting it to remain in the annular ring 10 and rotating it so that the cover and ring 10 are screwed oil the receptacle A. Ordinarily, however, the ring 10 will remain permanently upon the receptacle A, and merely the flexible cover B will be removed, it being observed that the upper end 16 of the ring 10 is beveled so as to facilitate application of the flexible cover.

In Fig. 2, the ring 10 is dispensed with as well as the bead 12, and the gripping means interposed between the flexible cover and the receptacle consists merely of the usual threads 18 which are gripped firmly by the expansible flange 5 so as to hold the cover in position.

In Fig. 4 the cover is formed with a domed portion which is much deeper than that shown in the other figures of the drawing, so

that the same can be more easily squeezed or manipulated to free the same from salt.

I am aware that it has been proposed heretofore to form the body portion of a salt cellar of rubber or flexible material, but in this form of salt cellar the neck ortion was formed of inflexible material amI a metallic cover was used, so that the disadvantage of having'the perforations of the metallic cover become corroded or clogged with salt was not avoided by the use of a flexible body portion. 1

Having thus described the invention what is claimed is A cover for receptacles intended to contain powdered material molded integrally of soft rubber and havin a perforated top which may be distorted by slight pressure to open the perforations when clogged, and a downwardly extending flange provided internally with projecting fastening means.

2. A cover for rece tacles intended to contain powdered material, molded integrally of soft rubber and having a perforated dome shaped top capable of distortion by slight I pressure to remove any clogging material in said perforations, and a downwardly extending flange provided on its inner side with attaching means.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses:
