IMPRovnD MQRTAR.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it 'may concern.:

being had to the accompanying drawings, and to the letters of reference marked thereon, which form a partof this specification, and in which is represented a perspective view of my improved mortar.

The nature of my invention consists in the employment, in connection withra mortar', of a revolving grooved platform or disk, rotating on a circular rail, secured to-a ame or table, and operated by means ot' a belt passing over two pulleyssecured directly/'opposite it, and thence over another pulley or driving-wheel, attached to a crank-shaft, having its bearings in the upper ends of vuprights 'seein-ed on each side of the' disk and mortar; in the lemployment of a sliding frame or cap, which is furnished, near and at its centre, with openings, and on its lower side with two cleaners; and also, in hingingv the pestle to a rod or bar, connecting with the crank-shaft above described.

A To enable others. to avail themselves ot' the beneiits of my invention, I will describe its construction and operation.

In the accompanying drawing,N N represent two boards, crossing each other, and united at the centre, thus forming a frame or table.

Upon this frame is secured a circular rail, formed with fianges bent down and penetrating the wood.

K is a circular' platform or disk, which is excavated or recessed on its upper surface, to receive the base of. the mortar A, in order to hold said mortar thereon, and provided on its circumference with a groove, the object of'which will be referred to hereafter.

M M are two uprights, secured on each side of disk or platform K, and made narrowA on a-portion o ftheir surface, near the upper end, as seen in the drawing.

C represents `a cap or frame, which is made so as to tit or rest at its ends on the shoulders of the uprights' M, formed by its reduction, and sliding up and do'wn This cap or frame is provided, at and near its centre, with openings, D and l?, the opening D being designed for the pestle to pass through while working in connection with the crank-shaft E, and openings l to allow the pestle to be attached firmly, by pin or otherwise, to the cap While in use Aforgrinding extra hard substances.

L .L are' two cleaners, secured to the lower side of cap C by means of thumb-screws, and made 4to extend down in contact with the inner surface of mortar A, to prevent the mortar from becoming clogged.A

B represents the pestle, which is made to extend up through the opening I) of cap C, and hinged or pivoled to the connecting-rod or bar. F by means of ,pin or key G, saidipestle and-connecting-rod or bar beingl provided with adjusting-holes, for the purpose of laising and lowering the said pestle, when desired.

The connecting-rod Fis-attached to the looped or cranked part of shaft E by means of a band or strap passing around the said shaft, and connecting at each 'end with the rod F.

E designates the crank-shaft, which has its bearings in the upper ends of uprights M, and supplied at one end with a wheel, to which is attached a handle, e, and provided at its oppositevend with a driving-wheel or pulley, H, over which passesfa belt or band, I, extending down over4NI two other pulleys, J J, having their bearings on an axle, j, secured to lower part of one of the uprights M, and thence around the groved re vol-ving platform or disk K, the object of said band or belt being to communicate a rotatory motion to the circular platform ordisk K. A

It will be observed that the rotating disk and mortar can both bere-moved from their original position, when desired, by merel y raising the sliding cap or frame G, with itscleaners.

What I claim', and desire to secure by Letters Patent, is-

1. The circular-grooved platform or disk K,rotated on a circular rail secured to the platform or table N N', in combination with' the mortar A, operated and arranged substantially as and for the purpose set forth.

2. The sliding frame or cap C, provided with the openings l) and P and cleaners L L, in combination with the uprights M and frame or boards N N', all arranged and operated substantially as and for the purpose set forth.

3. The pestle B, hinged to the connecting-rod F of crank-shaft E, arranged and operated substantially as described. l

4. Frame orboards N N', uprights M, axle4 j, pulleys J J, cap or sliding frame C, revolving disk or plat form K, mortarA, cleaners L L, pestle B,- connectingrod F, pin G, crank-shaft E, handle e, driving-wheelor pulley 'H,and bandeor belt I, when combined, arranged, and operated substantially as and for the purpose set forth. In testimony that I-claiin the foregoing as my own, I afiix my signature, in presence oftwo witnesses.
