This invention relates more particularly to dispensers for substantially desiocated particulate or comminuted materials l such as granular soap, iake soap, comminuted soap in the form commonly known as soap powder, and generall terials. The embodiment of theinvention shown in the accompanying drawings has been designed for dispensing a measured quantity of soap of the kind or nature above noted. It is obvious that it could be utilized for similarly dispensing other materials composed of powder, granules, particles, flakes, or other small fragments, should occasion arise, either substantially as shown or with suitable slight modifications therein.

One object ofthe invention is convenience in refilling the container, without liability of breaking a container bowl which may be made of lass or similar material. Other objects of t e invention are convenience of use and eectiyen'ess in operation. Other. objects of the4 invention are ease of disassembling'tor cleaning, strength, durability, simplicity of construction, and convenience and economy of manufacture. Other objects and advantages will hereinafter appear.

According to this invention a normally inverted container bowl may bereversed' in posit? on to bring itsinouth upward for loading or refillingr without removing the bowl and while it still remains securely attached to and supported by a rigidly mounted supporting bracket; also a bottom closure formed by a valve body or housing containing a dispensing valve mechanism may then be opened after the container has been reversed; also a single locking device in common is provided for securely maintaining the dispensing bowl in its normal inverted or dispensing position and at the Sametime preventing the opening of the housing which forms the bottom closure; also the invention Afurther includes a. particular construction ofthe dispensing mechanism or valve device which forms a measuring device for delivering a predetermined quantity of the material to be dispensed at each manual actuation. The invention further includes various features of construction and combinations of parts as similar divided solid mashowing a slight modification in the 192s. serial 30.277,628.

will appear from the following description. The-slightly variant embodiments of the invention which are shown in the accompanying drawings will now be described and thereafter the invention will be pointed out in claims, reference now being had to the drawin s, in which:

Fig. 8 (Sheet l) is 'a view of the flat side of a key in the form of a small spanner wrench to be used in opening the dispenser for refilling and in removing the valve member forpcleaning; I

Fig. 9 is a side view similar to Fi 2 but pensing mechanism and is a partial vertical section on the line 9 9 of Fig. 10; and

Fig. 10 is a front elevation partly in vertical section on the zig-zag line 10-10 of Fig. 9.

The particular construction Vof the dispenser shown in Figs. l to 6 inclusive of the drawings will be lirst described. A rigid supporting bracket comprises a horizontal tubular bearing-forming stem 1 which projects forwardly and is provided at its rear end with a large hollowed out circular securing flange 2 by which the bracket may be firmly supported by means of screws 3 on any convenient partial vertical section on the line 4--4' vertical wall 4. A strong horizontally arranged ring or annulus 5 1s provided at the back with a radial boss 6 into which is inset and cast therein the knurled end portion of a strong rearwardly extending horizontal journal stud or shaft 7 which is journaled 1n the bearing formed by the tubular stem 1. The shaft 7 projects into the hollow space formed by the securing flange 2 and isV there anchored against withdrawal from its bearing by means of a shoulder-forming washer 8 and a cotter pin 9.

A wide-mouthed inverted glass container bowl 10 has a large externally screw threaded neck 11 which screws into the upper side of the ring 5 with the inner cylindrical surface of this neck flush and in alignment with the inner cylindrical surface of the lower portion of the rin 5 (Fig. 2), this bowl being shown as glob ar. The bottom or lower side of the ring 5 is closed by a'valve body 12 which may` be opened. In the construction shown, this valve'body 12 is removably firmly held in place upon the ring 5 by means 'of a bayonet joint or bayonet slot connection. This connection is formed by means of a pair of diametral lugs 13 on the ring 5 which are received within an internal clrcumferential groove 14 formed in the valve body beneath an internal upper flange 15, this flange bein provided with a pair of diametrally arran escape slots 16 for the lugs 13 (Fig. 6). he valve body 12 carries a stop pin 17 for one of the lugs 13 which projects from the peri hery of the valve body into the groove 14-for 'miting the rotative movement of the valve body 12 on the ring 5 when the lugs 13 are enged i1)1 the groove 14 beneath the flange 15 In carrying out the invention, a single releasable lookin device is provided to prevent the opening o or the disengagement of the I bottom closing valve body 12 from the ring 5 and at the same time to prevent rotative movement of the plivoted ring 5 on the bracket stem l so that t ereby the above described reversible dispenser parts will be maintained in their normal upriglht position shown in the drawings (Fig. 1 an 2 particularly). In the construction shown, the bottom c osure or valve body 12 is provided at'the rear thereof v with an integral radial arm 18 which carries at its end a small vertically arranged head 19, this head being just beneath the outer or forward end portion of thel bearing-forming bracket stem 1. On its lower side the outer end of the bracket stem 1 has a small boss 20 in the lower side of which is provided a screw threaded socket. A screw pin 21, which is freely rotatable in the head 19, is screw threaded at its upper end and screws into this socket in the boss 20 (Fio2). This screw pin thus forms a locking lt. -It` has a hat head 22 countersunk into the lower side of the arm head 19. This head 22 of the screw y shank portion of the screw pin 21 is smooth and of reduced diameter while the bore in the head 19 which receives this pin is of reduced diameter and screw threaded in its outer or lower portion only, adjacent to the pin head 22. While this permits the screw pin 21 to be assembled 'by first screwin it into its bore and afterwards permits it reely to ro.

tate therein, it prevents this pin from ,dropping out and 'thus causing inconvenience or becoming lost when it is screwed out of its socket vin the bracket boss 20.

When the bowl 10 is to be filled or replenished with the material to be dispensed, the screw pin 21 is `first screwed out of or disengaged from the boss 20 of the bracketarm 1. When this is done then the ring 5, together with the bowl 10 carried thereby and also together with the valve body 12 carried thereby, may be turned completely over or vertically reversed so that uthen the bowl hangs downward and the valve body is at the top. Then the valve body`12 may be rotated to bring its escape slots 16 into alignment j with the lugs 13 on the ring 5, whereupon the valve bod ,together with all of the parts carried there y, may be lifted oft", leaving the bowl 10 with its mouth opening upward through the ring 5, for easy and convenient iillinffl without the necessity of either removing t from its supporting bracket arm 1.- Obviously, the dispenser may be restored to its normal operating condition shown in the drawings'by a reverse series of these operations.

It will be noted that the horizontal axis of the journal stud or shaft 7 intersects the axis of the ringr5 so that a proper balancing of the weight is secured. It may also be noted that the circular peripheral portion of the valve body 12 ts up closely and tightly against the bottom of the ring 5 and that similarly the flange 15 of this valve body fits up against a shoulder formed on the ring 5, so that thereby the valve body -12 forms a .tight closure 'for the lower side or bottoml of the ring 5 toprevent the escape of the contents of the container bowl 10. y It shouldalso be particularly noted that the above described bayonet slot connection of the valve body 12 to the ring 5 prevents this valve body 12 from falling or dropping oi after the screw pin 21 has been released from the bracket arm 1, while this screw pin when it is screwed into the bracket arm firmly clamps and holds the valve body 12 in place and also firmly and rigidly holds the ring'5, together with e bowl from the ring 5 or the latter Ydrical socket. The closing wall of its left hand end has provided through it a bearing which in part is formed by an inwardly proj ecting central boss 25. The bottom-forming portion 12 of the valve body at its inner or upper side is inclined o r slopes downwardly from the ring 5 towards its center and at the center is provided with an inlet aperture or supply opening 25"L into the shell 24 -(Figs.

2 and 3). lThis opening is circumferentially rearwardly enlarged and in part formed by more sharply inclined front and rear inner guide surfaces 26 and 27 respectivel j of which the front surface 26 is shown as o considerably less extent than the rear surface 27, for a reason which will presently vap ear. On its lower side, in alignment with t e axis of the'ring 5 and with the above noted outlet opening in the bottom closure 12, the shell 24 is provided with a downwardly extending somewhat liarin g delivery spout 28 of circular cross section which forms a downward diametral outlet aperture or downwardl Haring delivery passage 28 from the cy indrical shell 24.

A rocking cylindrical valve member or valve plug 29, forming a measuring dispensing valve, fits snugly but rotatably within the socket provided by the shell 24. At its ri ht hand end (Figs. 1 and 3) this valve mem r has a peripheral flange 30 which fits snugly u against the end of the shell 24. This end oi) the valve member 29 has formed integrally therewith a handle lever 31 which projects at an inclination downward and towards the right below and not far removed from the lower end of the delivery spout 28 (Fig. l) and normally substantially in line therewith (Fig. 4). At its inner or left end (Fig. 3) t e valve member 29 is centrally provided withla sli lit boss 32 which terminates in line with the inner end of the tubular boss 25 on the shell 24.

A squared valve stem 33 (Figs. 3 and 4) projects centrally 'from the left or inner end of the valve member 29 and is shown (Fig. 3) as having a round roughened end portion cast into the valve member 29 as an insert. An outwardly headed bearing sleeve 34 fits over the square valve stem 33 and within the bearing formed in the end wall of the shell 24 and its boss 25. The outer end of the valve stem 33 is reduced and screw threaded to receive a fiat nut 35 which is' countersunk flush into the head ofthe beariii sleeve 34 3) and this nut is provide with a. pair ofsmall socket holes as shown to receive the larger pronged end ofthe wrench key .23. In the construction shown, the rocking movement of the cylindrical valve member 29 is limited to about 45 by a peripheral lug 36 on this valve member just inward from its outer flange 30 and which works in an arcuate slot 37 provided in athickened portion of the wallof the shell 24 (Fig. 5), so that the ends of this slot provide stops for the.

lug 36.

A radial web 38 connects the internal bearing boss 25 with the walls of the cylindrical shell 24 (Figs. 3 and 4). A stud 39 projects from the a jacent inner end of the valve member 29 and is loosely received substantially flush in a notch provided in the clockwise side of the web 38 (Fig. 4), so as to be inserted or withdrawn a ong with the valve member 29. A helically coiled expansion` spring or push s ring 40 within the shell 24 at the bottom o the valve-receiving socket surrounds the inner bearing boss 25 and at its opposite ends presses with some initial tension yagainst the opposite sides of the radial web 38, thereby normally maintaining the valve stud 39 seated in its notch in this web. AThis spring 40 is a return spring for the valve member 29 and it normally holds this valve member at the rotative position thereof shown in the drawings, in which it is tion as viewed from the right side of Figs. 1 and 3 and as appears in Fig. 2, and also as is indicated by the position of the stop lug,

spring 40 remains in place in the shell and y,

under its original initial tension.

The cylindrical valve member or valve plug 29 has transversely through it a smooth aperture forming an uninterrupted continuous passageway providing an unobstructed dispensing port which in o eration constitutes a measuring pocket. n the construction shown, this port through the valve'plug 29 is ofbent shape being made up of two radial parts joine lat a circumferential angle at the center of the valve member 29 and comprises an upper radial part oir-portion 41 and a lower radial part or portion 42 which is vat an angle of substantially 45 out of alignment with the upper part 41 (Fig. 2). The upper part 41 is of slotted form along the length of the valve member 29 and tapers gradually downward until it is substantially circular at the center point where it smoothly joins or opens into the lower part 42 (Figs. 2 and 3). The lower part 42 is c lindrical and is of the same diameter as t e upper end of the downwardly flaring rotated to its limit of movement or as far as it will go in a right hand or clockwise direc- '100 outlet aperture 28s in the delivery s ut 28v (Figs. 2 and 3). Itwill be noted igs. 2

' and 3) that no shoulder or offset is formed where the port portion 41 joins the portion 42, but only a shght angle, which is rounded as shown, for the free flow o'f the material without lodging or sticking. 0

In the norml position of the dispensing valve 29 shown in the drawings the lower or form a material-receiving pocket which isclosed at its bottom and open at its top to be filled with the materialto be dispensed.

In operation, the handle lever 41 is pushed rearwardly to the limit of'its movement, for rocking the valve member 29 to its operated position. In this latter position of the valve member 29, the upper end -of the pocket formed by the two joined port parts 41 and 42 will be closed by the cylindrical wall of the shell 24, the upper part.' 41 then standing at an angle of about 45 while the lower port part 42 will be vertical and open in registering alignment with the outlet a erture 28* so that when the measured sma quantity of the material to be dispensed will drop out of the port or pocket of the valve member 29 through the deliver s ut 28 and into the palm of the hand he d eneath this s out. It will be obvious, particularly from Fig. v1, that the lever 31 may be conveniently operated or ushed back by the thumb of the right hanffwhile the palm of the same hand is held under the spout 28. As soon as this "lever 31 is released the springA 40 will return the dispensing valve 29- together with its handle to its normal position shown in the drawings so that then the pocket-forming port in this valve will again be filled in readiness for the next subsequent operation.

It should b e noted and will be evident from the drawings, particularly Fig. 2, that in the dispensing operation. there is at no time a free opening for the material being dis- `l pensed to run out ofthe container bowl 10 through the angularly joined or communicating ort parts 41 and 42 from the container w1 10 down through the delivery spout 28, since when the valve member 29 is rocked to effect a delivery the upper or inlet end of the port part 41 will be entirely closed by the adjacent portion of the wall of the shell 24 before the lower or outlet end i of the lower port part 42 begins to open into insaooe the lower port portion 42 will be entirely closed by the adjacent portion of the wall of the shell24 before the upper end of the upper port portion 41 beginsto open past the adjacent edge of the shell wall. Thus there can be no possibility of any leakage during operation. 4

The more sharply inclined portions or surfaces' 26 and 27 of the inner surface of the bottom closure 1 2 facilitate the feeding of the material through the supply hole 25a into the upper .ortion 41 of the port through the valve member 29. The forward or left hand (Fig. 2) incline 26 is made small and short, not cutting into the supply hole 25,thereby to assure the complete closing of the upper end of the port part 41 before the lower end of the port part 42 begins to open, and vice versa. The rear incline 27 may be made larger and longer as shown so'as to expose a portion of the cylindrical surface of the va ve member "29, so that thereby the rocking valve member` agitates the material suiiiciently to prevent bridging, caking or clogging thereof. y

The construction of the 4dispenser shown in Fig. 7 is modified or.varied from that shown in Figs. 1 to 6 inclusive just described only in the minor respects required to adapt or enable it to be mounted upon a horizontal surface such as the support.v 43, which may be thetop or slab of a washstand or lavatory basin. In this construction, the supporting 'bracket comprises an upright standard 44 having a base flange 45 and an inserted castinsecuring stud or rod 46 having a downwardly projecting screw threaded portion which may be screwed into or may pass through the slab 43 and be'secured inl place at the lower side of the slab by meansof a nut (not shown).

' The upper end portion of the standard 44 turns over forwardly on a curve to form a horizontal tubular bearing stein 47 integral with the standard. The bearing-forming bore of this stem 47 does not extend all of the way through at the back. A journal shaft 48 is rotatable in the bearing formed by the stem 47, the forward knurled end portion of this shaft being cast as an insert into-the boss ,6 of the ring 5, which thus together with the parts carried thereby is rotatably mounted uplon and supported by the bracket stem 47. T e inner orrear end portion of this shaft 48 is provided with a circumferential groove 49 in which is engaged an anchor pin 50 which enters the stem 47.

Other parts of the dispenser construction shown in Fig. 7 are the same as in that hereinbefore described in reference to Figs. 1 to 6 inclusive and such of these parts as appear have accordingly been'given the same reference numerals. It will be noted of Fig. 7 that the reversed or replenishing position of the ring 5 together with all of the parts caryet removed for "memos riedlthereby, including -the container bowl .10 and the' bottom-forming Yvalve body 12 which closes the lower end of the ring 5, is indicated in broken lines, with the container bowl 10 hanging down and with the bottomclosing valve body 12 atthe top, and as not the refilling of the bowl. Figs. 9 and 10 show a slightly variant form or modified construction of the dispensing valve or valve member with corresponding changes in the valve body shell, but in other 'respects this construction is the same as that hereinbefore described in reference to Figs. 1 to 6 inclusive, and maybe the same as that described in reference to Fig. 7. In this modification shown in Figs. 9 and 10 there is shown a cylindrical valve member or valve plug 51 which has through it a straight smooth diametral aperture or passageway roviding an unobstructed pocket-foming elivery port 52. This port 52 has two parallel sides while in the direction of the length of the valve member 51 it tapers downwardly so that at itsA upper entrance end or mouth `it is slotted along the length of the valve member while its lower or outlet endis circular, as will be clear from a comparison of Figs. 9 and 10. The normal or closed filling position of the valve member 51 is shown in the drawings.

The bottom-closing valve body 53 which closes the lower end of the ring 5 is provided, as in the iirst described constructiomwith a central supply opening or inlet aperture 54, but this valve body 53 has a valve-containing housing or shell 55 which is oset forwardly from the central line 'or axis of the ring 5 and from the central aperture or supply opening 54, while a delivery spout ,56 extends vertically downward from the rear portion of the bottom of this cylindrical shell 55 in central axial alignment with the supply Aopening 54 and ring 5. In the normal position of the cylindrical valve member 51 shown in the draw'- ings the supply opening 54 opens into the upper end of the port 52, which is in alignment therewith, while the lower or outlet end of this port is closed by the wall of the shell 55. In this normal position of the valve member 51 it will be noted that the diametral straight port 52 through this valve member is disposed at an angle from the vertical of about 221/2 with its lower end spaced forwardly from the outlet aperture 56 provided 4by the spout 56.

This valve member 51 has a limited rocking movement through about 45, as in the hereinbefore described construction. This operating movement is in a counter-clockwise direction as seen in Fig. 9 and as viewed from the right side of Fig. 10. The valve member 51 is integrally provided with a handle 57 by means of which 1t may bethus rocked against the tension of the return spring, such as hereshell this pocket-f .55. That is to usay,

inbefore described. When this valve member'51 is thus rocked the inclination of its pocket-forming delivery ort 52 will be reversed s'o that then it will) be disposed at an angle of about 221/2 with its lower end in registration with the upper end of the delivery outlet 56n provided through the spout 56 and with its upper end then covered b the upper and forward portion of the cylindrical wall vof the shell 55, as'will be readily understood from an inspection of Fig. 9. Thus a delivery of the measured small quantity of material contained in theport 52 will be made, after which the valve member 51 will be automatically returned by its spring to its normal position shown in the drawings.

In this modified construction shown in Figs. 9 and 10, similarly in this respect to the construction hereinbefore described, at no time during the operation is there a free pas.-A sagewa-y opened for leakage or for the Inaterial to run out of the container bowl 10y through its supply opening 54, the valve port 52 through the valve member 51, and the delivery spout 56. y This is prevented by providing a suiiicient overlap of the cylindrical wall 55 at the upper and lower ends of the valve port 52, asclearlyappears in Fig. 9 forthe normal position of the valve member 51. Thus ata midwayor intermediate position of operation of the valve member 51 orming port 52 will be closed at the cylindrical wall vof the shell as the valve member 51 is rotated or rocked in a counter-clockwise direction (Fig. 9) in a dispensing operation the lower end of the valve port 51 will not begin to open into the upper end of the delivery spout 56 until the upper end of this valve port has been entirely closed by the upper left hand portion of the wall of the shell 55. Conversely, as this valve member 51 is returned to its normal position by its spring the upper end of the valve port 52 will remain closed by the shell wall and will not begin to open until after the lower end of this valve port has moved entirely free of the outlet 56" provided by the delivery spout '56 and has been entirely covered or closed by the lower left hand portion of the wall of the shell 55. Thus a definitely and substantially accurate measured quantity of the material being dispensed is delivered at each operation. v f

In all of the constructions shown and above described all of the larger metal parts maybe die-castings Such parts, in Figs. 1 to 6 inclusive, comprise the supporting bracket having the stem 1 and integral ange 2; the ring 5; thevalve body bottom closure 12 together with its integral parts, including the arm 18 having the head 19, the valve shell 24 and spout 28; and the dispensing valve 29 together with its integral both ends by of a suitable metal such as zinc.

1 in ludlng the dispensing valve 51 together with its integral handle 57, and the valve body 53 together with its integral shell 55 and delivery spout 56.

It is obvious that various modifications may be made in the constructions shown in the drawings and above particularly described, within the principle and scope of the invention as defined in the appended claims.

As a further modification, for example, the bottom closing valve body, insteadof having as shown a bayonet slot joint connection to the ring, could be hinged thereto. In such case a simple snap catch could be provided to hold up the valve body when the locking screw pin shown is disengaged from the supf porting bracket. Obviously this arrangement is applicable to all of the constructions shown in the drawings. l
