DISTRIBUTING-BE GEPTACLE Specification of Letters Patent.

Patented March 23, 1909.

Application filed February 6, 1907. Serial No. 356,084.

To all whom it may concern:

Be it known that I,- WILLIAM RIGHTER' CoMINGs, mechanical engineer, citizen of the United States, residing at Wimbledon Park, in the county of Surrey, En land, have invented certain new and usefu Improvements in Distributing-Receptacles, of which the following is a specification.

The object of myinvention is to produce receptacles for distributing powders and the like, commonly known as dredgers, which shall be free from the tendency to clog. To effect this object I introduce one or more false lids, or diaphragms, under the dredger or sifting top, and I provide for these diaphragms to be adjustable with respect to their distance from the sifting top. I attach great importance to this distance bein kept as small as is consistent with a steady ow of the powdered material, in order to render it impossible for lumps to form in this space, as

well as to prevent the fine holes getting choked, and I make the dredger to adjustable with regard to the diaphragms y screw or other action, by which I am able to obtain complete control over the flow of the material, and can when required stop the flow altogether.

The diaphragm or diaphragms I pierce with one or more fairly large holes as compared with the sifting holes,,to allow a free unclogging flow of material to the siftingtop. The function of the diaphragm is to support the weight of the powdered material and thus prevent its clogging the fine holes of" the dredger end of the receptacle, as there is always a tendency to when the fullweight of the contents of the receptacle comes directly upon the dredger end. In some cases I make the diaphragm in the form of a lid, fitting the interior of the receptacle by looking, or with sufficient friction to retain it in any position that it may be adjusted to, so thatwhen desired it can readily be removed for filling the receptacle. fix the diaphragm rigidly or permanently at the top of the receptacle, and I then depend on the dredger top for adjustment. The dredger top being, adjustable can when required be brought into close contact with the diaphragm, thus closing its opening, or

openings, and protecting the contents from In some casesI may prefer to' moisture and the hardening or caking caused thereby.

In order that my invention may be more clearly understood I will describe the same by reference to the accompanying drawings, in which Figure'l is a part elevation and part section of an inverted dredger top cylindrical box. 'Fig. 2 is a plan of the top. Fig. 3 is a part elevation and part section of the same ut with dredger top removed for ouring.

Fig. 4 is a part section of a rectangu ar box.

Fig. 5 is a view of the same showing the ex-,

terior. Fig. 6 is a part section of a rectangular box with the addition of a spring or hinged division plate or bafiiler.

In Fig. 1 A is a cylindrical box of paper, tin, or other material, and B a perforated top made to screw onto the box A, and provided with asharp tapering spike D. G is an inner diaphragm or false top with a hole E in the center through which the spike D protrudes. The hole E is made to allow a certain maximum quantity of material to pass into the distributing space F and over and through theperforations O in the top B in a spray, as shown. Thetop B being screwed onto the box, it will be evident that by screwing the top on or off the area of the hole E in the diaphragm G can be varied, thus affording a means of regulating the flow of the material to and over the perforated surface of the top B, and when required stopping the flow altogether. Thespike D attached to and moving with the top, acts as a valve in controlling the flow of the material, but it is also designed for breaking up lumps, or caked material, by its sharp point, or, failing this the first time, it will serve a useful purpose in turning them aside, clear of the passage. For some pur oses the material contained in the box may e required to be poured out, in preference to sprinkling, in which case the perforated to B may be removed, when the material will ow through the orifice E in the g iaphragmin a single stream, as shown in In Figs. 4 and 5 I show a square or rectangular form of box I with two spikes J on the erforated top K, and two corres onding holes Lin diaphragm M. I may owever 'employ a larger number of spikes in cases air where the material is specially liable through dampness or other causes to cake or form into lumps. The flow of the material in such boxes is regulated by pushing the top up or down, a scale H marked on the extenor of the box indicating the depth of the distributing s ace, or distance between the top and diapiiragm, which will indicate in some measure the quantity of material allowed to pass through. I may also according to circumstances use a fiat spring or hinged division or bafiie plate N, between the diaphragm and to as in Fig. 6, in which case holes 0 and would be made in it so that the material on its way out is made to pass through a series of holes decreasing in size until it arrives distributed in a thin stream over the perforated under surface of the top; the flow being controlled as before by pushing the perforated top up or down.

eceptacles made as described not only give a greatly im roved form of distribution, but the flow of t e material can be varied within greater limits than with boxes as hitherto made. Also the weight of the material being removed from the perforated top prevents the top, when not screwed on, from being accidentally thrown off in the act of shaking, and by using more than one diaphragm I am able more effectively to deal with materials which easily cake or clog. In some casesI may prefer to dish the diaphragm nearest the perforated top giving it a downward direction so as to allow any material left in the distributing space to readily flow back into the receptacle.
