Specification of Letters Patent.

Patented May 9, 1908.

Application filed April 10, 1997. Serial N 0. 367,871.

To all whom it may concern:

Be it known that I, ARTHUR J. BLOOD, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Receptacles for Granular or Pulverulent Materials; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to receptacles for containing and dispensing granular or pulverulent material, and more particularly to an improved so-called sifting top for such a receptacle.

The object of the present invention is to produce a simple and effective top or closure provided with a revolving disk and to so construct the disk that it may be readily turned for the purpose of opening and closing the receptacle wlthout liability of injury ,to the fingers of the operator.

Further objects of the invention will appear in connection with the following description of its construction and mode of operation.

To the above ends the present invention consists of the im roved receptacle which will be hereinafter escribed and claimed.

The present invention is illustrated in the accompanying drawing in which Figure 1 shows a broken vertical sectional View, the line of cutbeing substantiall parallel to the operating bar or handle. Fig. 2 shows a to plan view with portions of the revolving fis broken away to show the underlying construction. Fig. 3 shows a fragmental sectional view taken on the line x-x, Fig. 2. 4 shows a top plan view of a modified form. Fig. 5 shows a fragmental sectional view taken on the line yy, Fig. 4. Fig. 6 shows a fragmental sectional view taken on the line z2, Fig. 4.

Similar reference characters will be em-- the receptacle has been fille by the to 2,

which is preferably struck up from s set 2), an a group of slots 8 (see Fig. 2), these openings being arranged preferably as shown at-equal distances from each other and near the peri hery of the receptacle.

It will be of course understood that when a large mass of material is desired at one discharge it will-be ermitted to esca e from the openin 6.. on less materia is de- 2, the group of small perforations 7 (see sired, it wil be permitted to escapefrom'the Y openin s 8, and the openings 7 W111 of course be use when still less material is desired.

' Cooperatin with the openings 6, 7 and 8 is a valve dis 9, which is provided with an opening 10 and this opening 10 is arranged to be brought into register with one or the other of the o enings 6, 7 and 8 by turning the disk 9. he disk 9 is formed of sheet metal and is provided diametricall across its center with a cross bar 11, stan ing vertically at right angles to the disk. The disk 9 .and the cross bar 11 are preferably formed integral with each other and thisis conveniently done by stamping the disk 9 from' sheet metal substantially in the form of an ellipse, the central portions of which or'the excess of the material sufficient to produce a circle, will be struck u and brought into close contact, thus forming the cross bar 11 and roducing from the elliptical blank the circular disk 9, having the cross bar 11.

Thedisk 9 is pivotally connected to the top 2 and this may be secured by cutting from the Walls of the cross bar 11 at its center the flaps or tongues 12, which are turned down and overla each other upon the upper surface of the isk 9, as shown clearly in Figs. 1 and 2, and through .these overlapping tongues is passed a rivet 13, which secures the revolving disk 9 to the to 2. In order that the disk 9 may be tight yheld in contact with the u per surface of the top 2, the

lower end of t e rivet is passed-through a may s ring washer 14, the tension of which is sufcient to draw the disk 9 in close contact with the u per. surface of the top 2.

If desired, in order to form a close union and to provide for the more effectual sealin of the device, the top 2 may be rovide with a circular depression 15 and t e disk9 with a corresponding circular rib 16 arranged to take into the depression 15. This construction forms a guide and support for the turning of the disk 9.

It will be observed b the foregoing construction that the revo vin disk 9 is rovided with a strong and rigi cross bar w ich be grasped by the fingers of the operator and readily turned for the purpose of moving the opening 10 into register W1th any one of the openings 6, 7 and 8, and this without liability of injuring the finger nails or fingers of the o erator; and it wi 1 be further observed that y depressing the top 2 above the upper edge of the receptacle the cross bar 1'1 will be seated in a recess and thereby protected from injury. I

If desired, the to of the receptacle after it has been filled and the top 2 and disk 9 secured therein, may be covered by a removable ca or cover (not shown) for shi ment.

In Fig. 4 there is shown a modified orin of the devlce in which the revolving disk 9 is provided with a cross bar 11 formed in the manner heretofore described, and is likewise provided with overlapping tongues 17 and adjacent to the tongues 17 the cross bar is cut out to form the win s 18 which are turned outwardl at right ang es to the cross bar 11 and at their bases may be soldered to the upper. surface of the disk 9, thus forming strengthening ribs or braces, all as shown in Figs. 4, 5 and'6.

Having described my invention I claim as new and desire to of the United States 1. A receptacle for granular or pulverulent materialhavin a fixed top with an openin clearly (therein, a revo ving disk pivotally mounted protect by Letters Patent.

thereon and provided with an opening and having a cross bar diameter of the disk and at ri ht angles to the surface thereof, said cross ar and disk bein formed from a substantially elliptical blank, substantially as described.

2. A receptacle for granular or pulverulent material havin a fixed top with an opening therein, a revo vin disk ivotally mounted thereon and provi ed wit an opening and having a cross bar extending across the diameter of the disk and at ri ht angles to the surface thereof, said cross ar and disk being formed of sheet metal struck u and compressed alon one diameter, su stantially as described.

3. A receptacle for granular or pulverulent material having a fixed top, a revolving disk struck up at its center along one diameter to form a cross bar, a tongue out from the cross bar at its center and a rivet passed throu h the tongue and the fixed top, substantia y as described.

4. A receptacle for granular or pulverulent material having a fixed top, a revolving disk struck up at its center to form a cross bar, overlapplng tongues cut from the cross bar at its center and a rivet passed through the overlap ing tongues and the fixed top, substantial y as described.

5. A receptacle for granular or pulverulent material having a fixed top, a revolving disk struck up at its center to form a cross bar, overlapping tongues cut from the cross bar at its center, a rivet passed through the overlapping tongues and the fixed top and strengthening braces cut from the cross bar and turned outwardly therefrom and secured at their lower ends to the disk, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses.
