PACKAGE FOR POWDERED MATERIAL.

SPECIFICATION forming part of Letters Patent No. 587,517, dated August 3, 18977.

Application led February 2, 1897. Serial No. 621,709. (No model.)

To all whom it may concern:

Be it known that I, BERNARD BAR, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain Improvements in Packages for Powdered Materials, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a perspective view of a receptacle containing my invention. Fig. 2 is a side elevation, enlarged. Fig. 3 is a vertical section on line as x, Fig. 2. Fig. 4 is a horizontal section on line y y, Fig. 2, showing a slight modification of the gate or cut-oft'. Fig. 5 is so much of a vertical section of a modification as is necessary to illustrate a modification. Fig. 6 is a partial vertical section of another modiiication. Fig. 7 is a partial vertical section of another modification. Fig. 8 is a partial vertical section of another modification. Fig. 9 is a horizontal section of the construction indicated in Fig. S, taken on line e .a of that figure.

The invention relates to certain novel features of construction and combination of p0rtions of the receptacle which will be pointed out in the claims.

Referring particularly to Figs. l, 2, 3, and 4, A represents the body of an ordinary receptacle for powdered or ground material of any sort--such, for instance, as tooth-powderand has a bottom A', these parts being made of thin sheet metal or other suitable material, such as is commonly used for this kind of packages, and is by preference circular in cross-section, although many of the devices are adapted to be used in packages which are angular in cross-section, as will be explained.

The cover is indicated by B B', the depending flange B being of somewhat greater diameter than the body A, so as to form an annular space or chamber between the tlange and the upper end of the body.

a is a rib or bead projecting outward from the body at the lower edge of the depending flange.

C is a delivery guide, lip, or chute attached to the flange with a discharge-opening c in the upper end of the body and a corresponding opening Z) in the flange. (See Figs. 3 and 4.)

D is a gate or cut-oft disposed in the annular or partial annular recess or chamber above referred toand indicated at b2, Figs. 3 and 4. In Fig. 4 this gate is shown as being in the form of a complete ring, and it is preferably of such width as to practically iill the space between the top B of the cover and the bead or rib a, with a discharge-opening d, which when the gate is turned into the proper p0- sition will register with the discharge-openings b c, but of course when the gate is in the position shown in Fig. 4 no material can pass through those openings, or the cut-on? or gate may consist of a comparatively short section of a ring, as is indicated in dotted lines in Fig. 2, in which case the annular space between the iiange B and the upper end of the body A may be made correspondingly short, having only suflicient length to permit the gate to move endwise such distance as shall be found necessary to permit the opening and closing of the dischargeopenings, as will be readily understood without further explanation.

d is a thumlrpiece, the shank of which passes through a slot b in the flange B.

Vhen a package of this general character is used for tooth-powder, the discharge-openings require to be so large in order to insure a reasonably free delivery that with ordinary care a quite large portion of the material is wasted by being scattered instead of being delivered upon the tooth-brush, which is too narrow to catch the powder as it falls, such scattering being also otherwise objectionable; but by the use of my invention the converging sides of thechute collect the powder and insure its being discharged in a'small stream, which can be readily delivered upon the upturned ends of the bristlesof the narrowest brush that is sold, it being of course understood that the receptacle can be held in the proper position and the gate opened and closed by the use of one hand only, the thumbpiece d being moved in the requisite direction by the thumb or one of the fingers, as the case may be.

I am aware that oil-cans and similar receptacles for liquids havebeen provided with a spout attached to the can at the place Where the hole for the liquid to run out is located, so that said spout will receive the liquid and direct its delivery, as may be preferred, and I am aware that dredgingboxes have been made with a row of small holes near the upper end, with a corresponding series of registering holes in the downward projecting flange of the cover, the imperforate portions of said flange closing the holes ofv the box when the cover is turned into the right posi tion, the relatively small sizes of the holes necessitating a quite violent shaking of the box to insure a proper delivery of its contents, which are usually scattered over a quite large area, a mode of operation which would be entirely impracticable in a package like mine, which is designed more particularly for dentrifices, and in which it is important to have a relatively large single discharge-opening, combined with some device for prevent-- ing the scattering which invariably occurs with a series of openings, so that the toothpowder can be freely dischargedwith but a slight jarring or tapping of the box with one finger, and yet the powder be delivered upon the very narrow space occupied by the upturned ends of the bristles.

I am aware that in the oil-can above referred to there was a cylindrical gate-section,

but it was supported upon the bottom of thev can. and could not be supported from the rial-may flowl to the chute.

In' the modification shown in Fig. 5 the gate or cut-oft` E is held in position on the inside ofthe receptacle bylips or flanges e, one

on either side, soldered to the receptacle, and is moved up and down by the thumb-piece e', whichzprojects through a slot d.

In Fig. 6 the discharge-opening is in the upper end or head of the box to which the chute is attached, and the gate or cut-off consists, essentially, of a cylinder section F, which carries at its upperend a head or disk G, provided with a discharge-opening g,which can be made to register with opening b when the cut-oii is turned to the proper place by means ofthe thumb-piece f, which works in a slot a2. (Indicated in dotted lines in Fig. 6.)

In Fig. 7 the cover itself is made-to serve asa gate or cut-off, it having a` dischargeopening b, the same as in Figs. l to et, andhaving the chute attached in the same way, but fitting somewhat loosely, so that it can be .easily rotated to open and close the opening c, `with a pinY b3 projecting vinward from the depending flange B and traversing an angular slot a3 in the upper end of the box, so that the cover can lbe put on by sliding the pin down through the vertical part of said slot, when by turning the cover around until the pin is within the horizontal part of the slot the cover will beheld against accidental removal, while if the relative positions of the partsbe those indicated in thedrawings the ange at the end of the slot nearestthe opening b will serve as a stop to insure that the openings shall register when the cover has been turned as far in that direction as is possible, and by examining Fig. 7 it will be seen that when the pin is at either end of the slot `the cover will be held against removal.

In Figs. S and 9 the gate consists of a quadrant-shaped plate H, pivoted at h to the under side of thetop of the box, with a depending flange I disposed in a recess'between the Acover and the adjacent part of the box and rotated backward and forward by a pin h', which projects upward through a slot b2 in the top of the box.

That I claim isl. In areceptaclefor powdered material,. the combination of a box having a cylindricalA wall and-provided witha discharge-opening,-` a chute disposed to receive material from said; opening, a cover having a discharge-opening a gate having a vertical cylindrical section supported in close contact-with the box, and means for rotating the gate, substantially` as .set forth.

2. In a receptacle for powdered material, the combination of abox` having Va cylindricalwall and provided with a dischargebpening,

opening, a cover having adischarge-opening through which material can flow to the chute gand a vertical flange supported in close conf Ftact with the box., andmeans for rotating the flange, substantially as set forth. 3. In a receptacle for powdered.y material, Qthe 'combination of abox having a cylindrical fwall and provided witha discharge-opening,` a cover, a vertical recess between-the cover and the adjacent wall of the box, anda gate disposedv in the recess, substantially as set forth. 4. In a receptacle for powderedY material,` the combination of a box having a cylindrical wall, a cover having a depending'flange fitting loosely the upper endof the box, andia-` agate disposed ybetween the flange and the box, j substantially as set forth. Y g 5. In al receptacle for powdered material,` the combination of a boxl having a cylindricaly wall provided with a discharge-opening,a`v cover having an external depending flange also provided with a discharge-opening, `and la chute attached to the flange, and means for 4connecting the flange with the boxandper- `mitting the flange to be rotated to serve asa.` gate, substantially as setforth.

In testimony whereof I affix my. signature in presence of two witnesses. A i BERNARD BAR.
