STORAGE RECEPTACLE Filed Nov. 18., 1929 2 Sheets-Sheet 2 2? 4 ATTO/Q/VEX Patented May 3, 1932 PATENT OFFICE CARL BUSCH THORNE, OF HAWKESBURY, ONTARIO, CANADA STORAGE RECEPTAGLE f V I Application filed November 18, 1829. Serial No. 408,091.

The invention relates to a storage receptacle, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

' The invention consists essentially of the novel features of construction pointed out broadly and specifically in the claims for novelty following a description containing an ex- ,r planation in detail of an acceptable form of m the invention.

The objects of the invention are to store slowly moving materials which are to some extent semi-fluent, that is to say, they flow largely from their own weight and fill up any receptacle in a comparatively short space of time, and require some assistance in their Withdrawal to insure a continuous discharge of the material especially into measuring boxes or compartments, which may be of any form; to facilitate proportioning material from the tower; to maintain the levelling of material in a tower constant during the discharge operations, that is to say, the usual condition of the contents of a receptacle containing slowly-moving material is a distinct sinking in the centre while at the edge the material clings to the wall, therefore all new material entering pours down this naturally formed funnel which leaves a considerable quanity of the contents almost permanent and at the same time detrimentally affects the discharge, and it is to avoid this condition of affairs that the constant level is to be maintained, so that in discharging the material 8 5 drops at the edges as quickly as it does in the centre and therebetween, keeping up a continuous emptying movement for deposit in the measuring apparatus to facilitate the operations in paper mills, silk mills, storage ware houses, or other manufacturing places, so that the desired grades of pulp or other material maybe kept in storage and constantly drawn and always fresh material secured; and generally to provide in mills or other establishments storage for raw or partly manufactured materials that may be tapped at will and yet kept in good condition.

In the drawings, Figure 1 is a vertical sectionalyiew of the lower portion of a tower, tank, bin or other receptacle and a longitudinal sectional view of a plough member r0- tatably mounted and engaging the bottom portion of the receptacle.

Figure 2 is a cross sectional view of the tower or other receptacle showing a plan View of the plough member.

Figure 3 is an enlarged perspective detail of the plough member.

Figure 4 is an elevational view of one form of the storage receptacle.

Figure 5 is an elevational View showing a modification of the storage receptacle.

Figure 6 is a cross sectional view of the storage receptacle illustrated in Figure 5.

Like numerals of reference indicate corresponding parts in the various figures. Referring to the drawings, the receptacle is here shown as a tower, indicated by the numeral 15. j

The bottom 16 of this tower sloops inwardly and is inclined downwardly from the tower wall to the central discharge opening 17 at the bottom of which is a measuring chamber 18, that is to say, while a plain box is shown below the discharge opening any desired form of measuring device may be used in that box.

In the centre of the frame forming the box the shaft 19 projects upwardly into the tower through the bearings 20 and 21. At the upper end of the shaft the hub 23 of the plough member 22 is mounted, said plough member being supported on the bearing 21.

The arms 25 and 26 of said plough member project in the direction of the walls of the tower and terminate in proximity thereto and the arm 25 carries the blades 27 and 28 of arcuate shape in longitudinal section and projecting therefrom in a direction to sweep the floor of the tower in cooperation with the blades 29 and 30 projecting from the arm 26 in alternate positions in relation to the arms 27 and 28 so that every part of the floor is swept by these blades of arcuate shape.

The radial levelling blades 31 and 32 and 33 project from the hub 23 of the plough member and extend downwardly below the floor within the measure 18, so that the material within said measure is levellel off continuously and dropped .out in the most approved manner to be constantly refilled.

The shaft is shown as operated by the gear mechanism 34 suitably driven, and the discharged material is shown as transported by any suitable form of conveying mechanism indicated by the numeral 35. y

In the operation of this invention, the tower is charged with material such as pulp for the manufacture of paper, silk and other products or with any dense or granular material, and this material remains in storage until it is desired to withdraw a small portion of it or a considerable portion of it, or all of it, as the case may be, or to be continuously withdrawing and recharging,

' The discharged material is prepared for by placing some sort of receptacle underneath the central opening preferably a measure of some kind and then the shaft is retated and this rotates the plough member which sweeps the floor completely with its arcuate blades, these blades directing and even urging the material in to the central discharge opening.

The blades being alternately placed on either side of the hub, the movement of the flow is even from the side wall of the tower to the centre thereof, because these arcuate blades are simply sliding the material inwardly from the outside in' a continuous flow towards the centre, and at thesame time the material itself is dropping in the centre at an even rate which insures a perfectly level surface of the contents continuously during the discharging movement for the levelling blades in the centre have their function, which isinconjunction with the arcuate blades to maintain a perfectly level surface of the discharge material, consequently as all the members contributing to the outward flow of the material are associated in centering an even drop of the material throughout the topmost level is maintained and the tower emp tied evenly, so as to insure freshmaterial at each recharging.

In Figures 5 and 6, another form of storage receptacle is s'hown in which the bottom end is completely open and across this bottom end the several conveyers operate, which instead of sweeping an inclined bottom, as described in referenceto the earlier figures, form the bottom themselves and operate through it, these conveyers having transverse divisions which not only constitute a means of measuring the materials withdrawn from the receptacle, but maintain the surface level of the contents evenly from wall to wall.

This particular receptacle is shown in the drawings as square or rectangular so thatthe distributing member must travel in endless conveyers thereacrossf I The casing in this form of the invention is indicated by the numeral 36, and it is completely open at the lower end, while the-conveyers are indicated by the numeral 37 and the transverse divisions by the numeral 38.

These are endless conveyers and are driven in any suitable manner and discharge on to other conveyers or into another chamber or receptacle.

In this secondform of the lnventlon there is still the radial movement, but it 1s extended to form a flooring for the receptacle which may be stiffened in any desired manner to bear the weight, and the conveyers continuously pass across the bottom area and divisions engage the material from the bottom end, and this engagement is in the way of distribution so that all parts of the contents thereabove are effected, thereforethere is no particular drop at any one point, simply sinking evenly and correspondingv with the discharge.

What I claim is K 1. A storage receptacle comprising a tower having an inclined bottom surrounding a discharge openingand a levelling member mounted for rotation and having its arms cutting the contents in a horizontal path and its blades extending downwardly into proximity with the bottom in gradually reducing depthstowards the tower walls for. the purpose of reducing the height of the contents in the center in relation to the height at the wall.

2. In a storage receptacle, a tower having its'bottom inclined slightly to a central discharge opening, a discharge receiving box extending into said opening and forming a.

well therebelow and means for levelling the contents of the receptacle and progressing it to said receiving box.

3. A storage receptacle comprising a tower having its bottom sloping in a gentle incline tom, a shaft suitably journalled and driven g and projecting centrally through said opening'and a levelling member having arms turning in a horizontal path through the vessel contents, and-arcuate blades projecting from said arms and in rotation with said shaft sweeping the entire bottom surface surrounding said opening.

'5. In a storage receptacle, a vessel having a central discharge opening through the bottom, a shaft suitably journalled and driven and projecting centrally through said opening and a plough having horizontal arms forming levelling members and extending into the proximity of the vessel wall and also having curved blades of varying depths proquantities tol jecting from said arms in alternate positions on either side of said shaft respectively in groups and together covering the bottom in rotation.

6. In a storage receptacle, a vessel having a central discharge opening through the bottom surrounded by the bottom sloping at a gentle incline, a shaft suitably journalled and driven and projecting centrally through said opening and a plough member mounted on said shaft and having horizontal arms levelling the contents and blades in rotation sweeping the material down said incline and also having radial blades from the hub thereof projecting through said discharge openmg.
