IMPROVED SPICE-GRATER.

To ALL WHoM 1T. MAY coNoERN:

Be it known that I, H. W. OLIVER, of New Haven, in the 'county of New Haven,'and State of Connecticut, have invented anew and improved Spice-Mill; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a new and improved arrangement for keeping and grinding spices of various kinds; and the invention consists in combining and arranging a number ot' tubes or cylinders in such a manner that while the tubes severally contain diierent kinds of spices, either one of the spices may be ground separately from the rest, and by the same means or by the same grinding-disk by which all the rest are ground; and also in the device for feeding the spice into the mill, and also in combining with the mill a case or receptacle, which is itselfl an indispensable article of the household.

Figure 1 represents a longitudinal vertical section of the mill within its case, through the line :l: of fig. 2.

Figure 2 is a cross-section of the mill' and case combined, through the liuc y y.

i Figure 3 is a longitudinal section of the mill, showing an outside view of the mill or grinding end.

,Figure 4 is a view of the revolvingplate which 4covers the grinding end of the cluster of tubes, showingv the aperture through which the unground spice is vforced by the spiral spring.

Similar letters of reference indicate corresponding parts. l

The tubes marked a, tig. 2, (more or less in number,) are contined together, as seen in the cross-section. The length of the tubes is indicated by the longitudinal section,.iig. 1, where the mill is represented in its case. b represents plugs or short cylindrical pieces, (one in each tube,) which have thumb-pieces c with small projecting lipsl d, as seen in the drawing. e is a pin which is attached to the centre of the cluster of tubes, with a head, f. To each of the pins b there is a spiral spring attached, which springs have pistons or plates attached to their opposite ends, as seen at g, g. 1. h represents the springs. J is a screw which acts as a pivot or centre for the plate z', tig. 4, to revolve upon. '.lhis' plate has a broad flangeV aroundit, as seen in iig. 3, and one orifice, m, which is of the diameter of the tubes, with as many holes through the flange as there are tubes. c is a spring having a pin in its end, which enters the holes in the ange as `the plate is revolved, andthe holes are so arranged that when the spring holds the plate by the pinl the hole m through the plate will correspond with one of the tubes, and that tube is indicated by the index-finger n 'which is attached to the iange of the plate. To turn or revolve the plate, the spring is pressed down, when the pin on its end leaves the hole in the flange and allows it to turn. The grinding is done by another disk-plate o which is revolved by the crank I). This grinding-plate may be formed in any suitable manner, so that it is made to perform the required service. In this example of my invention the plate is perforated in the manner of a grater, while the spice (which is represented by the red color) is pressed against it by the spiral spring. Steel cutters or points may be attached to the grinding-plate if desired; The grinding-plate is supported by the central screw Jion which it revolves. On the inner side of this grinding-plate there are little ledges, seen at l lll, iig. 3, which are for the purpose of keeping the two plates a suiflcient distance apart to allow the ground spice to be discharged from between them, and also to prevent contact between the plates.

To operate the mill, the piece 6 (at the opposite end) is turned so that the projection d leaves the head of the pinf, when the spring is withdrawn from the tube and the spice is introduced. rlfhe spring, with the piece 6, is then replaced and thegrinding-plate isrevolved, the indexnger pointing to the tube containing; the spice to be ground. Thc'case or receptacle for the Inill S is made in the form of a rolling-pin, and it is designed to be used for that purpose. It is formed of a metallic cylinder, with Wooden heads and handles, one of which heads is removable, as seen at S in the drawings.

The mill can be securely kept in the rolling-pin case, and consequently it will always be found when it is wanted for use;

The different spices may be kept in the separate tubes of the mill, secure from dust, and where they will always be at handjvhen wanted.

p Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

` The tubes a, (more or less in number,) arrangell and combined substantially as shown and described for the purposes specified.

In combination 'with the tubes a I claim the method herein shown and deserihedfor feeding the spice tothe grindingplate. l

I claim the langefl plate Az', the spring 7c, and the index n, for the purposes set forth. I claim 'the grinding-plate o in combination with the tubes a. I claim the case S in combination with the spice-mill, constructed substantially as described for the purpose set forth. i H. W. OLIVER.
