DISPEN SING APPARATUS.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application tiled April 25| 1906. Serial No. 313.618.

T o all whom. it may concern:

Be it knownl that I, GL'sTAvE J. HOLL, a citizen of the United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented a new and useful improvement in Dispensing Apparatus, of which the following is a specification, reference being had to the accompanying drawing.

My improvement relates particularly to mechanism for dispensing liquids and also solids when the latter are in the form of powder or granules or pellets or similar small masses adapted to run or ilow by gravity.

One of the chief usi-s to which my apparatus is to be put is the dispensing of soap and similar cleansing materials, over or adjacent to a wash-bowl, the apparatus being adapted to discharge small measured quantities fron a larger quantity contained in a reservoir, sai: reservoir being substantially hermetic` ally sealed in order that evaporation may be avoided and in order that the soap if placed into said reservoir in sterilized condition may so remain.

In the accompanying drawings, Figure 1 is a fragmentary side elevation showing my improved apparatus applied to a tloor, wall, and wash-stand; Fig. 2 1s an upright section of the upper nirtion of the apparatus shown in Fig. 1, said section being from front to rear on the indirect dotted line, 2 2, of F ig. 4; Fig. 3 is a fragmentary view looking at the front of the apparatus, the measuring mechanism being inverted for the removal and rciilling of the reservoir; Fig. 4 is a horizontal section on the line, L1 4, of Fig., l; Fig. 5 is a. detail view of a portion of the bell-crank and the horizontal connecting rod; Fig. (i is a front view of the wall bracket; Fig. 7 is an upright section on the line 7 7 of Fig. 1, looking in the direction of the arrow.

Referring to said drawings, A is the floor, and B is an upright wall oil a room, and C is a wash-bowl attached to said wall.

At a short dist-ancov above the wasn-bowl is a wall bracket, 1, secured immovably to the wall, B, in any suitable manner, as by means of bolts or screws, 2, extending through said bracket into the wall. To the outer portion oi' said bracket is applied a circular or disk form head, Si, having an approximately centra-l aperture, 4, and 1n its upper edge a notch, 5. To the front face of said head is applied a circular plate, 6, having a rearward-directed circumferential iiange, 7,

fitting closely around the circumferential edge of the head, '3, the rear face of said ilange being approximately flush with the rear face of said head. applied to the rear face of said ilangc by means of screws, 9, and extended over a portion of the rear face of said head. T hus the circular plate, 6, is held rotatably upon said Binding plates, S, are

head, the rotation being on a horizontal axis.

The plate, (i, has anaperture, 6, located opposite the aperture, 4, in the head,

A notch, 5, is formed in theinne" face of the. llange, 7, opposite the notch, 5; and a spring arm, 7, has one end resting in said 70 When said free to rotate.

From. the upper portion of the circular plate, 6, a reservoir-supporting member, 10, extends hln'izontally-orward. Said plate and said member are preferably integral and the plate may be considered a part of -the member. In the forward portion of said member, 10, is an upright aperture, 11, through which project; a bolt, i2. Loosely surroundmg said bolt below the bracket is a.

measuring cylinder, 13, the lower face of said Y bracket heilig dressed smooth and even to make a close tit with the upper face of said cylinder. Said cylinder is shown as having four upright chambers, 14, each extending entirely through thel cylinder, 13. Below said cylinder, said boli, 12, is surrounded by a bottom plate, E5, which has a downward directed sleeve, 16, extending through an arm, 17, which arm also surrounds said bolt. And said plate, 15, has a` notched lateral extension, 15, which bears against the circular plate, 6, to prevent rotation of said plate, 15, on the bolt, 12. Inunediately below said sleeve said bolt is surrounded by a washer, 18, adapted to bear against said sleeve, and below said washer an expanding coiled spring, 1S), surrounds said bolt and bears against said washer; and below said spring said bolt is surrounded by another washer, 20; and below the last mentioned washer, said bolt is surrounded by a nu' 21, supporting said last mentioned washer. By means of said nut.

i l t Salti W or. Ttj opressed upward so that the bottom plate, 15, is made to bear closely against the lower face of said measuring cylinder. The. meeting faces of said cylinder and said bottom plate are to be formed smooth and even so that liquid will not pass between them.

At the front of the bottom plate, 15, is a depending spout, 15b, with which the chambers, 14, may, one at a time, register. Below the mouth of said spout is a guard, 15. Said guard may be. integral with the spout. 1t docsnot extend into the path o the discharge from said mouth. Thus the material discharged does not touch said guard and does not become contaminated by any in aterial adhering to the guard. The purpose of the guard is to keep thel hands of persons who wash from bearing against and contaminating the mout-h of' the spout.

At the rear of the bolt, 12, an interior-lythrcaded nipple, 22, extends upward; and a passage, 23, extends through the bracketfroni the interior of said nipple downward into proper position to conununicate with the chambers, 14, of the measuring cylinder, 13.

A l. ott-leform reservoir, 24, having an exteriorly-threaded neck, 25, is threaded into said nipple, 22, in the inverted position.

f Upon the perimeter of the measuring c vlinder are four equi-distant ratchet teeth, 26, Aadapted to be engaged by a pawl, 27. Said pawl is hinged upon the arm, 1T, by means of an upright screw, 2S. An expanding spring, 29, bears against the arm, 17, and an. extension, 30, of the pawl, 27, and causes said awl to normally bear against said measuring cylinder.

To the lower portion of the bracket, 1, is hinged an upright bell-crank, 31, and the upper arm of said bell-crank terminates in a ring, 32, and said ring is coupled with the ring, 33, of a horizontal connecting rod or bar, 34, which extends through the aperture, 4, in the head, 3, and the aperture, o, in the circular plate, 6, and is hinged to the upper face of the arm, 17, by an upright screw, $5.5.

From the lower arm of the belhcrank, 31, a connecting rod, 36, extends downward and has its lower end coupled to a treadle, 37, which treadle may be supported in an)y suitable manner, as bv being hinged to a chair,

38, at 39, the relation of the parts being such as that the pedal end of said treadle will be in its elevated position while the pawl, 27, is at the forward limit of its range of movement.

The reaimost chamber of the measuring cylinder, 13, becomes iilled by the flow of material downward from the reservoir through the aperture, 11. Each movement of the trcadle imparts to the measuring cylinder a quarter rotation so that the irst movement of the mda] moves the rearmost chamber of the c inde-r to one of the lateral positions, and t ie next movement of the treadle brings said aperture to the iront `so as to register with the discharge spout. The

vbottom-plate covers all ol the. lower face of the cylinder, excepting tbe portieri at the spout, so that the chambers of the cylinder are prevented from discharging until they register with thc spout.. Thus, when the amparatus is in practical use, each operation of the treadle causes the contents of one chamber of the cylinder to discharge by gravier through the spout.

Yt'hen the apparatus is being manufactured, the meeting faces. of the reservoirsupporting member, the measuring cylinder, and the bottom plate are made. smooth and even' so that when they are pressed together, they will Vlit so closely as to prevent thc passage of air. and spring whereby said member, cylinder, and bottom plate are held to each other, any wear of said meeting laces' may be taken up so as to maintain the close meeting of said faces. In fact this construction is adapted to develop a closer lit ol' said faces by wear; for the rotation ol said cylinder has a grinding ctie; t adapted to causo said meeting faces to coliform more closely to each other, and after such grinding, said spring and bolt continue to press said member, cylinder, and bottom plate against each other.

dien the material stored in the reservoir becomes exhausted, the l`ree end of the .spring arm, 7, is pressed downward, whereby the reservoinsupporting member is rendered free to rotate upon the head, 3, of the bracket, 1, until the reservoir is in the approximately inverted position shown in F ig. 3. Then the reservoir is nnserewed from the nipple, 22, and refilled and again screwed into said nipple. 'lhcn said supporting member is rotated in the reverse direction until it has assumed its normal position, whereupon the spring arm or key, 7, springs outward into the not-ch, 5, whereby said member is again locked.

When the material is being discharged from the chamber registering with the spout, the place of said material in said chamber is taken by air rising through the spoilt, so that when said chamber moves forward and again becomes covered by the bottom plate it is full of air. And when it again assumes the rearmost position, so as to register with tlf-e aperture., 11, the air contained by said chamber rises into the reservoir as the material in the reservoir descends. In this wav, the forming of a vacuum in said reservoir is avoided.
