shakers, powder boxes, and the like which have perforated tops and a perforated valve movable in respect thereto so as to open and close the perforations and permit or prevent discharge of the contents of the vessel.

The object of my invention is to so construct such a dispensing vessel that the valve will be normallyretained in the closed position; all leakagewhen the valve is closed will be prevented; no part of the valve, or of the spring which closes it, will be accessible to the contents of the vessel; there will be no outside exposure of the valve, ex cept as to the thumb piece whereby the valve is operated, and the structure w1ll be compact and inexpensive.

In the accompanying drawing Figure 1 is a transverse sectional view of the upper end of a dispensing vessel constructed in accordance with my invention; Fig. 2 is a sectional plan viewl of the same on the line a-a, Fig. l; Fig. 3 is a view similar to Fig. 1, but illustrating another construction embodying my invention; and Fig. 4. is a sectional plan view on the line b-b, Flg. 3.

In Figs. 1 and 2 of the drawing, 1 re resents the upper portion of the bod of t e vessel and 2 the cap of said vesse which may either be integral with the body as shown, or may be secured to said body in any desired manner, such cap having therein pertorations 3 disposed as desired. To theupper portion of the vessel is fitted a cover 4f, preferably having a dished or depressed central 'portion 5 which is perforated as at 6 so that its perforations register with the perforations 3 in the cap 2.

Between the cap 2 and the dished portion 5 of the cover 4 tits a laterally sliding valve 7 which has a thumb piece 8l projecting through a slot in`the cover', as sh0wn in Fig. 2, the inner face of this valve bearmg against a flat spring 9 which is contained in one of the chambers formed between the cap 2 and cover 4, outside of the limits of the dished portion 5 of the latter, as shown in Fig. 1. The spring 9 bears at its ends againstthe inner face of the side wall of the cover 4, as shown in Fig. 2, so as to have a constant tendency to press the valve 7 outwardly and thus carry its perforations 10 out of register with the perforations 3 and 6 formed in the ca 2 and cover 4, thereby closing the vesse both against the discharge of any of its contents and againstthe access of moisture, dust, or any other foreign matter to such contents.

When it is desired to discharge any of the contents from the vessel pressure of the tnumb or finger upon the thumb piece 8 will.

move the .valve 7 inwardly until its perforations register with those of the cap and cover of the vessel, the latter perforations being closed again, however, as soon as the pressure of the thumb or finger is removed from the thumb piece 8.

In Figs. 3 and 4 I have illustrated my invention as embodied in a vessel having a swinging valve 7, the latter having a central pivot stud 11 which is adapted to central openings in the perforated portion of the cap 2 and cover 4., both of the latter be ing dished in those portions in which the perforatio-ns are formed so as to produce outside of the limits of said dished portions, a chamber of somewhatlarger size than that, shown in Fig. 1, this chamber receiving a coiled spring 9u which bears at one end against a lug l2 projecting inwardly from the cover 4 and at the other end against a wing 13 projecting outwardly from the perforated and swinging valve 7 from which also projects the thumb piece 8 which plays in a segmental slot 14 in the cover 4, this slot being of such dimensions as to permit swinging movement of the valve 7 to an extent sufficient to carry it-s perforations 10 `into or out of register with the perforaticns 3 and 6 of the cap 2 and. cover 4, the tendency of the spring 9 being to move the .valve 7 to such position that its perforations shall be out of register with the others. Either form of valve lits snugly between the cap and cover of the vessel so that when the valve is in its closed position any leakage of the contents of the vessel is prevented as is also the ent-rance of moisture or external impurity into the vessel, the contents of which are therefore always kept dry and in an uncontaminated condition, and by reason of the fact that no portion of the moving valve or of its actuating spring is accessible to the contents of the vessel there is' no possibility of said contents clogging the valve, all portions of the valve and its operating spring being inclosed with the exception of the unobjectionable projecting thumb piece. The valve attachment does not materially increase the size of the vessel or add materially to the expense of t-he same.

1. The combination, in a dispensing vessel, of a perforated cap and a perforated cover havm a. chamber between them, with a perforate valve movable bet-Ween the cap and. cover so as to o en and close the perforatio-ns therein, an a spring contained in said chamber and serving to move the valve to its closed position. f

2. The combination, in a dispensing vessel, of a perforated cap and a perforated cover, one of such members being dished in that portion in which the perforations are formed, a perforated valve movable between said cap and cover so as to open or close the tained between said ca perforations therein, and a spring also coni and cover/l in a chamber outside of the dlshed portion of the same, said spring acting uponthe valve so as tov move the same to a closed position.

3. The combination, in a dispensing vessel, of a perforated ca and a erforated cover, either of which 1s dished 1n its perforated portion, a perforated vvalve movable between said cap and cover so as to open or close the perforations therein, and

a spring contained in a chamber between the cap and cover beyond the limits ofthe dished portion, said spring bearing upon an abutment in' said chamber and also upon a projecting. abutment on the valve an tending to move the latter to the closed p sition. In testimony whereof, I have signed my name to ythis specification, in the presence of two subscribing witnesses.
