To all whom it may concern:

Be it known that I, JAMns TALBOT Rnavn, a subject of the Kin" of Great Britain,r'esiding at as and .39 flalf Moon. Street, Piccadilly, London, England, have invented new and useful Improvements in Appliances for Delivering Substances in Powder Form,

- the appliance that the weight of the powder'ed substance serves to close the valve instead of employing an independent weight vfor the purpose. y p g In a suitable arrangement for carrying out the invention the powder is carried in a container in the form of a lining movance and normally resting upon the bottom of the body which bottom may be open. The container has a tubular valve at the lower part which co-acts with a central rod or'stem fixedto the body to effect the discharge of the powder when the container is raised and lowered.

The valve and central stem may be so constructed that, when the powder container is lifted, an opening is established for the discharge of the powder through the valve,

such discharge being maintained until the container is lowered to enable the valve to cutoff communication with the said container. In this construction the central stem may have a disc thereon which fits within a hole at the bottom of the container, which hole opens into a tube of larger diameter than the said hole, the said tube extending downwardly from the containerand serving for manipulating the latter. Or, the tube can be dispensed with and any other suitable downward extension employed.

Instead of the construction just described. the valve and stem may be formed so that the discharge of the powder can only take place in measured quantities. For. this purpose, the central stem may be provided with a cylindrical head thereon fitting within a. vhole at the bottom of the containerftand which hole opens into, a depending tube of similar diameter. Below the head, the tube 1923. Serial No. 651,119.

is enlarged fora distance slightly less than i the depth of the said head.

In another arrangement,-the central stem may have two heads, preferably of double conical, globular or ellipsoidal form and the depending tube is formed with two enlargements normally located below the part of largest diameter of the two heads, respectively.

In a further construction for delivering the powder in measured quantities I form the discharge-valve or stem enlargement and the disc, or valve for normally closing the lower end of the discharge-tube, integral and separate from the supporting stem, and

preferably of porcelain or other nonmetallic material. I also provide the said discharge-valve with an upward extension to form the support for the loose conical valve,

other non-metallic'material, and I'make the discharg-tube of inverted conical form to .facilitate the discharge of the powder. able vertically within the body of the appliin the casing by a turning movement, and

held after such movement by'a stop thereon engaging with a projection on the lid which is hinged to the said casing. The'projection on the lid may take the form of a lockbolt for securing the lid itsclosed position.

Means'are also employed for preventing 'the container from .being lifted when the apparatus is out of use, such means comprising a stop slidable on the guide above referred to, so that it can be interposedin the'path of the said container. 4

The body is formed with a bracket extension to enable theapparatus to be supported by nails or the like on a wall or other upright surface.-

By arranging the container for the powder to be movable, as described, it will be seen that the movement necessary to obtain the discharge of the powder will have a tendency, especially if the lowering movement takes place quickly, to shake the powderand prevent clogging.

To enable the invention to be fully under stood I will describe it by reference to the accompanying drawing, in which Figure 1 is a vertical section of apparatus which is also preferably of porcelain or for delivering powdered substances, constructed in accordance with the invention and Figure 2 is a similar view of the lower' portion but'showing the delivery valve in a different position.

Figures 3 and4 are sectional views showin slight modifications of the delivery va ve.

Figures 5, and 6 are, respectively, similar views to Figures 1 and 2, illustrating further modifications.

valve used in this modification, and

Figure 13is a used therein.

plan of a guide-plate also a is the body of the appliance and b is the container for the powder, the said con-.

tainer being in the form of an open-topped lining loose and movable vertically within the said body and with its bottom 0 normally resting on the bottom d of the latter, which is -0 en. In the drawin this bottom 0 extends ownwardly, as indicated, as this i is the preferred form, but it may terminate just below the container 6. e is the depending tubular valve at the lower part of the container]; and is the central rod or stem attached to the ody a and passing within the said valve to co-act therewith to effect the discharge of the powder as hereinafter described.

The upper part of the body is closed by a cap 9 secured bya bayonet joint 1:. or in any other suitable manner whilstthe stem ,f is secured to the said cap. In the drawing, the

, stem is adjustably carried on the cap 9 by the nut i screwing on the said stem, but other means of adjustment may be em ployed. It also passes through a guide-hole in a plate 9 carried by the body.

'In the construction illustrated in Figure 1, the valve is constructed to deliver the powder in measured quantities and is of the orm wherein the stem f is formed with two heads 7, f of double conical form loosely fitting within the tube 6 and the latter is formed with two enlargements, e, e which are normally located below the part of largest diameter of the said heads f f respectively. By this arran ement when the powder contamer is liftedby pressure applied to the lowerpart of the. tu e e to the position shown 1n Figure 2, the uppermost enlargement e registers with the space around the central stem f to receive a charge of wder, which, when the container is again lowered to the normal position in Figure 1, falls into the space between the two heads f, f and is onlydischarged on the next up and down movements of the container, the lower enlargement e registering with the said space and receivin the charge on the upward movement, whic charge on the next downward movement of the container, is brought below the part of the lar est diameter of the lower head f and so is free to fall out of the tube 6.

The heads f and 7, instead of'being of the double conical fof'rm illustrated, maybe globular or ellipsoidal.

Figure 3 where the stem 7 is providedwith a disc j fitting within the hole in the bottom c of the container, which hole opens into the tube e which isof larger diameter than the said illustrates the construction hole so that directly the saidtube and con tainer are lifted, the powder will be allowed to escape below the disc j. Or the tube 6 can be dispensed with and :other downward extensions employed for manipulative purposes.

Figure 4 shows the arrangement for deliv-- the head thetube is enlarged as at l for a distance sli htly less than the depth of the head. Byt is construction, when the tube e and container 1) are moved upwardly, the K said enlargement Z is brought into communication with the. space within the container around the stem containing powder, which latter therefore falls into: and fills the said enlargement and which, .when the latter, again arrives below the head k, will fall therefrom and tube '0."

Figures 5 and 6 show another .construc-. tion of appliance for delivering a measured uantity of powder, somewhat similar to t at shown in Figure 4, thatis to say,'with a cylindrical head 70 on the stem f normally through the lower end of the" loosely fitting within the hole in the bottom c of, the container but with the tube e of e ual diameter throughout its length, but 0% larger diameter than the said head is. Above the head It on a collar f adjustable on the stem f is supported a loose hollow conical valve m so placed as to provide,

.when in the normal position indicated in Figure 5, an annular space between it and the bottom 0 of the container to allow a quantity of the powden in the latter-to pass into the space beneath the said valve, which quantity, on the raising of the tube e into the position shown in Figure '6, will fall past the head is and out of the bottom of stem f is provided at the lower end with the coned disc n which also serves to close the opening at the lower end of the said tube when in the normal position shown in Figure 5, and prevent access of moisture to the inside of the tube e of the container, and serves to spread powder on the hand. The tube 6 is advantageously made with the lower part (2 removable, as shown, to allow the stem 7 to be easily placed in position and withdrawn, thesaid part 6 being fixed to the upper part 6 in any suitable way.

The construction illustrated in Figures 7 to 13 is similar to that illustrated in Figures 5 and 6, but the discharge-valve or stem enlargement l: and disc or valve n are formed integral and separate from the stem f which is provided with a head or shoulder f upon which the said combined valves are supported, the said valves being secured to the stem by cement or otherwise. is the extension on the valve is for supporting the loose valve m in its normal position on the stem 7'. As hereinbefore stated, the integralvalves is and n. and the loose. valve m arepreferably made of porcelain or other non-metallic material. The discharge-tube e is of inverted conical form to facilitate the discharge of the powder, and is provided with a cylindrical prolongation f below the valve 11 and a wire loop f depending therefrom, the latter serving for actuating the container by the hand of the user but preventing it coming into contact with the lower end of the said prolongation which contact would interfere with the distribution of the powder thereon. is the guide for the upper end of the stem f, which guide is in the form of a circular or wheel-frame having projections g on its periphery for engagement with bayonet slots 0 in the body a by a turning movement, the

centre of the frame having a hole 72 for thereception of the upper end of the stem 7 which is secured thereto by a split pin or collar q. This guide 9 also serves'as a stop to limit the upward movement of the container b when in use.

1 is the lid which is hinged at r to the body a and serves, by means of a projection.

s thereon, (in the drawing, shown as a lockbolt) engaging any one of a series of stops on the guide to prevent the latter from turning in the body a when the said lid is closed down, the said lock-bolt then being shot to prevent access being obtained to the interior of the apparatus by unauthorized persons.

t is the stop, slidable on one of the arms of the wheel-shaped guide g, which stop,

when adjusted thereon can be interposed in the path of the container 1), as indicated clearly in full lines in Figure 10. \Vhen the said stop is moved to the position indicated by the dot and dash lines in the said figure, the container can be lifted to discharge the powder.

u is the bracket extension on the body a provided with inverted key-hole shaped slots r to enable it to be engaged with the heads of nails or the like on a wall or other upright surface.

I am aware that it is known in appliances in Will 11 the discharge valve 18 operated by hand to deliver powdered substances in.

measured quantities, but to such delivery 1 make no claim per se.
