VALVED BOTTOM-DISPENSING SALT SHAKER.

Application filed December 28, 1921. Serial No. 525,365.

To all .u-lzom if may concern.

Be it known that I. ALEXANDER M. las xiii. a citizen of the United States. residing in the city of Norwich, State of Connecticut. have invented a new and useful Improvement in Valved Bottom-Dispensing Salt Shakers. of which the following is a specification.

The invention is an improvement in valved bottomdispensing salt shakers or like table articles such as disclosed in my prior Patent, No. 1,366,929 of February 1. 1921. The ob j'ect of the improvements is to provide a simplified construction, and one which facilitates the filling of the shaker and enables the discharge to be regulated while preserving the other special utilities of this type of device. To this end the invention may be said to consist in the novel device, and the parts, improvements and combinations hereinafter described in preferred embodiment, and more particularly pointed out in the appended claim.

In the accompanying drawings forming a part hereof:

Fig. l is a central vertical section showin the spindle and valve in elevation;

Fig. 2 is an elevation on a smaller scale showing the cover in position for filling the shaker through the top; I Fig. 3 is a plan view corresponding to 'Fig. 2;

Fig. 4 is a central vertical section through an alternative construction of the cap having the spring barrel cup formed, integral therewith; and

Fig. 5 is an elevation of the spring connected together.

i The shaker has an upright holder 1, the salt chamber 2 of which has a sloping bottom 3 terminating in a central throat or discharge opening t. A hollow base or foot 5 below the throat affords a discharge mouth 6.

The throat is normally closed by a tapered plug or valve 7, the lower portion of which seats upwardly against the throat. Above its seating portion 8 this plug is formed with a series of transverse corrugations 9, of diminishing diameters. said corrugations serving to break up lumps when the plug is depressed and to cause a controlled discharge of the salt through the annular outlet between the plug and the throat when the plunger and plug is depresscdgthe plug beinc workedable cover 15. This cover has a. depending circumferential rim 16, which slips over a circumferential seat 17 on the top of the receptacle. and in the construction shown in Figs. 1 to 3 its top is formed with a central opening 18. of a size to receive the cup 14 which is inserted downward from the top, the'cup having an outturned top flange 19 to retain it upon the cover. The spiral spring 12 is interposed between the bottom of this cup, which has a small central opening for the passage of the spindle 10. and the under part of the button 11. and as clearly shown in Figs. 1 and 5 the spring and button are preferably connected so that they form a unitwhen the plunger is disconnected from the spindle. This is accomplished in an advantageous manner by forming the button with a bottom nub 20 having flaring sides, whereby an undercut groove is formed for holding the top convolution of the spring. In the modified form of cap 15 shown in Fig. 1, the cap and the cup 14 are formed integral.

In either construction the cap is held closed by the downward action of the spring 12, which also acts upwardly to hold the valve plug 7 closed. In order to till the receptacle through the top, the cover and spring barrel cup are slipped upward'on the plunger and spindle until the rim flange 16 clears the top of the receptacle, when the cover and operatingparts can be tilted sidewise. as seen in Figs. 2 and 3, thus uncovering a substantial part of the top of the receptacle. This is particularly useful in the ease of coarse salt. Fine salt can be filled into the receptacle around the plug by uncovering the receptacle and unseating the plug.

It will be observed that the plunger button 11 is provided with an elongated screwthreaded adjustment bore 21 for the reception of the screw-threads on the upper portion of the spindle 10. This adjustable c.onnection. 1n OOHJIIDC'LIOII with a stop shoulder 22 on the plunger adapted when depressedopening of the throat 8 when the plug 7 is unseated to be regulated by the user, thus (letermining' the freedom of flow under different conditions.

hat is claimed as new is:

A shaker having a receptacle provided with a bottom throat, a downwardly displaceable plug normally closing saicl throat, a spindle extending upward through thereceptacle, a spring, urging, the spindle and plug upward, the upper portion of said spindle being: screw-threaded, an operating but-ton having an elongated screw-tlneaded hore adjustably receiving the screw-threaded end of the spindle, and cooperating sto 'i surfaces-"on the button and receptacle respectivel limiting the downward displacement of the plug, the construction being such that screwing the plug up or down on the stem varies the normal distance between said stop surfaces so as to re 'ulate the extent of opening of the plum
