SUBsfrANcns AND Tini. niiiiV v lApplication filed September 7, 1928, Serialv No. 304,406, and in FranceSepteniber 16, 1927.

My invention has for its object a dispensei` more particularly adapted to be used in connection with pulverulent substances such as talcum powder, face powder,soap and the 15" like, and from which the dispensing of said substances `is effec-ted automatically.

The container preferably comprises a sta'- tionary cap-shapedv upper portion having an apertured flat bottom, and, below .this upper portion is a movable frame whose center'is provided withv a inemeshed wire-cloth.A This movable frame is operatively connected. to the cover of the container.v i

The subst-anceV to be dispensed is put into d the container through its bottom portion from where itis pushed against the upper apertured part by a coil spring.

. Vith'this and other objects in view the invention consists in theconstruction, combination and arrangement of parts as will be more fully hereinafter described, illus'- tratedin the accompanying drawings, and pointed out in the hereunto appended claims. Inthe drawings, illustrating by way of eX ainple'several embodiments of the invention, Figure 1 is a'section andV Figure 2 a plan view in partial section vof the container with open lid; Fig. Sis a plan view showing the details of the bayonet-joint of the movable 3@"lowerpart; Fig. 4 is section of another embodiment comprising a device whereby the outlet of thepowder takes place only from the ycentral portionV of the container, and .in which the bottom part is provided with an Aup-turned ythreaded, rim; Fig. 5 is a plan viewv in partial section of the container shown in Fig. with open lid partially broken away Fig. G is a section through its lower part;

; Fig. v7 is-a plan view in partial section of a container .with pinion driven operating mechanism; Fig. 8 is a .vertical partial section through the operating mechanism shown y in Fig. 7 Fig. 9 is a plan view in partial sec- 455 tion of a container in which the distributing mechanism is operated by a hinged handle; Fig.v 10 is a part vertical section of the mechanims shown in Fig. 9;l Figs. '11 and 12uarepart .vertical sections illustrating an'operating mechanism comprising blocks mounted for sliding movement upon appropriately shaped slides. I

ln a preferred construction shown lin Figs. 1 to 3, the container comprises a main body y l portion 1, a stationary cap-shaped upper part 2, and a bottom part4,removably connectedv to the mainvbody portion by means of its rolled Vedge 5.

Connected for free rotary movement to the bottom part l by means of a pivot 8,1 6.0"

provide a. disc 7 carrying a coil spring 6, the upper end of which is connected to a groo-ved piston 9 provided with rubber 4packing 10i The powder or other substance to be distrib- 1 uted is laidvout upon the upper face 11 of 65 this piston which, under the action ofthe spring 6, is urged against the aperturedflat bottom of part 2. Preferably the upper face of the piston is suitably roughened or coveredkvvith a suitable vfabric or the like, so as to .hold the powder inplace and prevent its f following the movement of the frame 12, andthus provide afregular and unobstructed passage 'of the powder through the apertures 3. As shown in Fig. ofthe movable framev 12is provided with teeth 13 while its central portion is made up of ine-meshed wirefcloth 1/1, or the like.

The frame itself is mounted for rotary move-y mentwithiii the groove l'provided in the 80 bodyof casingl so that the' same shall at all times remain in'close Contact with the lower apertured face ofQthe'cap-shaped part 2. Y. The hinged part 16 of the cover-17 is con-r nected to the frame 12'bymeans of a lug l18 85 extending from the latter and through a slot 19 provided in the main body portion 1 ofthe container; a sliding plate 2O is provided to close the slot`19 so that no spilling 1 of powder may occur through this opening. 90

The lower joint ofthe hinge 16 is rigidly fixed to the sliding plate 20. p The cover portion 17 is recessed in its'cen-` tral part so asto form a receptacle 21 to hold rouge ror a powder puff, or rlhis receptacle is closed by the lid 22'wliich latter may, if desired, carry a mirror.4

In a preferred embodiment the closing and opening ofthe lower part of the container maybe effected as follows: the rolled edge 100 2, the inner periphery V 3 kindred articles.

5 of the bottom rplate 4 is provided with notches 24 and 25 (Fig. 3) adapted to engage corresponding ears 26 and 27 upon the main body. Then now rotating the bottom plate, said ears will enter the groove formed by the rolled edge 5, while the spring 28 penctrates into the cut-out 29 securely locking the bottom plate in position; to unlock the same a slight pressure is exerted upon the spring 28 and the plate is turned in the oppo- V site direction until the notch-es and 253 vare opposite the Aears 26 and 27.

In a modiied construction illustrated'in Figs. l and 5 l have shown the holes provided in the upper cap-shaped portion occupying only a restricted area in the centr-al part thereof: In this way the powdeil will not be wiped off 'by the powder puita and spilled outside the container as often happens when the holes `are divided over the full areaof the bottom of the cap.

In order to prevent the powder from becoming clogged beneath the plain portion of the cap 2, the movable fra-me ll2comprises helicoidally shaped arms or scraper.,4 30, 8l {iX-ed -to sai-d frame (Fig. These arms, upon rotating the device, continuously return the Vpowder from beneath the plain `to- 'B Wards the central apertured vportion of the cap 2. D ue .to the particul -r shape of the arms it will `be read-ily seen that,l in order to return the powder to the central part, the

rotation of the dev-ice can tahe place in one direction'only. lith this result in View., l preferably provide upon the outer periphery of the fra1nel2ia series of saw teeth 32 cooperating with Aa. pawl 38 mounted -upon the hingefl of the cover 17 in such way, that, upon imparting a back and Yforth .movement to the latter, the trame will be rotated inr the desired direction. In this embodiment also, the slot 19 is closed by the slidingf 'plate 20.

f As shown in AFigs. 4t and 6, 'thefbottom plate 4t, insteadoibeing connected to the main body portion l by bayonet oint may be Vfixed thereto by either *inner or outer thread connection.

.7 and 8 show in detail a modiied device w iich lmay be used in controlling,` the movement of frame 12. In this device as in the others the loose powder is held `aga/in st the movable trarne 'by -inoa'ns of a vpiston 9 (sce Fig. l) with ia `spring G vand carrying disc 7'. In this -case the movable frame l2 carries a flat extension 18 which is enclosed within a corresponding protuberant hollow part 60 ot the main body l. rlhis lboss is so dimens-ioned as to allow for 'free back fand forth movement beiner controlled Aby means of a pinion vengaging in holes 100 provided upon the extension 18.

The shaft llt) carrying the 'pinion 1410 eX- tends through an opening 120 cut in the embossed part-60. The inner endcf theshaft is ycarried upon a support 180, while its outer end is provided with a control knob 150 of which the inner face is hollowed out so as t0 embrace the shape of the protuberant part 60 and bear upon the recesses 170 formed therein. ln this way the prominence of the knob is reduced to a minimum, While the free space upon its periphery 160 to be -gripped by the fingers is at the saine time incr-cased.

W'hen turning the button alternately towards the right and the left, the movable trame l2 `will describe a back `and forth movement and nause the powder to escape through the holes '3 of the cap-shaped part 2.

F 9 .and l0 show in detail a further modiied control device for use on a container with a spring; pressed piston and plate 7 l(lsee ig. In the modified control device the bach and forth mov-ement ot' the movable frame 121s eliiected by means of a handle 230 which is connected byva hinge 16 -to a flat portion 1S eXtendiirg` from the fra-ine l2. Asl-Ot 1.9 provided the main body part l ctor the passage of the port-ion 18 is closed .up by a slidinp late 2OM When not in use.J the handle lded (flown and securely locked against rotary movement by means ofthe hook 250 formed upon ltlie outer point of the handle and engaging' in this position the roll-ed edge 5 of the bottom plate Ll.

ln a further modified construction :of the con-trol device :for traine l2 yshown `in Figure 1l, the wall of the main body partis `constitut l bythe cir-cular parts 18th 270 and T260 ch are a-'bly conn eoted to the lup per an d 1' parts respectively of the container. A handle J30 with 'hing-w24() is connectedto the part 280,290 which in turn is connected by a plateSOQ to abolt 340 Venclosed Within a circular channel termed on one side by the - inclined branches 260 and 270 and on the oppositesid-e bythe wahl-80. ,l Tghe movable frame 12 is connected in any suitable mann-er, preferably here. shown by r-iveti-r-igg` thereto -a plate 32@ and the powder is held in place against the trame bythe spring pressed-.piston and plate 7 (see Fig. l) l Fig: l2-shows still another ormof control device in which the circular wal-l of the main body is formed by .a 4hollow part 350, 360. Arranged for sli-dino' -movement Within the part 350, 360, l lprovide a guide 39 of which an extension, protruding through a slot carries. lined upon its outer edge, the :hinged handle 23 A plate l0 provided upon the opposite edge of the guide 39 extends through a slot 38 to the interior of the Ebody portion l and is connected in any-suitable manner to `the movable vtrame. The powder is held in p'lace against trame l2by the spring pressed piston and plate '7 (see 1').

Bv rotatingi handle`230 'of the device shown in l1 and l2 the powder `or other fsub- .stance in the container is ,pushed upward towards and through the fholes f3 provid-ed in the capesha-ped part 2.

y 65. foraminous top wall, a lid for said container It is well understood that the movable r0- tating or sliding frame inserted between the substance which is to `be distributed, and a perforated plate, may be either round, reotangular or any other shape desired and that such plate may describe either a rotary, rectilinear, or any other -desired movement.
