` Leiters .Patent No. 61,954, drt-tred February `12, 1867.

mrsovtn Mmcme Emre.

Be it known that I, HELEN M. REMINGTON, of the city of Springfield, in the county of Hampden, and State of' Massachusetts, have invented a new and vuseful Improved Mineing Knife; and I do hereby declare that g n 0 u `the following is a full, clear, and exact description thereof, referenccbcmg had lo the accompanying drawings making a part of this specilieation, and/to the letters of reference marked thereon, iu`\\'l|icl1 FigureV 1 is a perspective view. l

vFigure l is a plana'ieiv.

Figure is :t vertical section through line A B of lig.

Figure -i is a vertical longitudinal section of thc handle C.

Figure 5 is a plan and elevation of the ringer clamp. y

Figure 6 is an elevation showing the cup (l and point c fitting into it.

Figure is a vertical section ot' part of the stem 71. andcupcl; and

Figure S is an elevation of thc foot 7c, showing slot for the knife.

rIhc nature of my invention consists in multiplying or increasing the number of knives used in mineing meat, so that there will be ainuch` greater tota-l length of cutting .edge operating at the saine time than by the usual method of using one blade; and this, too, without any considerable increase in expense over the common knife having one blade. I accomplish this by grouping or using three or more knives, made as hereinafter described, in such manner as that they shall be firm and strong, and using them in the same way as the common mincing knife of one blade is used. I am aware that three or more knives have beenused together for mincing meat, but this has been donc only when they have been used in connection with' and were dependent upon the operation of much more `expensive and often very complicated machinery; and on account of its expense and complication, such machinery has been almost entirely impracticable for general domestic use. l But my method of using a group o1-number of knives entirely removes these objections, as they can be manufactured withany desirable number of knives, 'without any great increase of expense or outlay over the common mincing knife, and at the same time is so free from complication that any ordinary servant can use, separate, clean, and put them together again without any inconvenience or trouble whatever. 4

To enable' others skilled in the art to make und use my invention, I will proceed to describe its construction and application to use. i

I make the shank, to which is attached the handle, in three or more sections or portions--sixsectlons or portions are shown on the accompanying plan--so that when the number used are put together they shall form collectively a cylindrical shank, as shown in an elevation; iig. 3 showing a vertical section of the same. The part h terminates at the bottom in a. curved leg, 4b, at the bottom of which is the foot c, having a vertical 1ongi tudinal slot ma'de in it, into which is inserted the knife or blade c, which may be kept in pla-ce hy the rivets oo. The upper end of the part h is made somewhat smaller than thc main portion,land having a shoulder at i. The

4 cylindrical clamp or ring a is made so that when the several parts, 7L 71, of the shank are put together, and form a cylinder, the insi'dc of the cylindrical clamp or ring a shall'iit on vto the cylindrical shank, and shall lrmly hold thc'sectional portions of the shank together,fo1'ming a firm, round shank. At mis a shoulder, against which the cylindrical clamp or fing a stops when it is forced down overthe cylindrical shank formed from these sectional portions 7L 7L. When these parts, 7L L, are thus put together, and a round shank is thus formed, a screw-thread,f, is eut upon the upper or small end of the cylindrical shank, or thesectional parts L z, collectively. A hole is made in the middle `oi' thc handle C, and into this hole is firmly inserted the socket g, wllich may be held in place either by clongating any portion of it, or by a key,or any other suitable means; and in the socket g is cut a female screw-thread, which lits thc screw-thread j', cut upon the upper end of the cylindrical shank. Instead of the sccketg being inserted in the handle C, I may use a ring, of sullicient-width, passing around, or slipped on to the handle C, and of suliicient thickness and strength to have a. hole made in one side, and a female scrowthread cut in that, which may answer thc purpose of a socket, and which I consider as its 1^iuivalent. The handle is then screwed down upon the shank tightly, and the portion n of the socket g strikes against the top of the cylindrical clamp or ring a, and forces it down against the shoulder fm, while the operation of the screw-threads at the top of the shank pullslup the several portions of the shank, and thus holds them tightly in place. To fucilitatelthe putting together of the sectional parts h t, to form a cylindrical shauk,-I number the sectional parts i lt on the top or other convenient place, or letter them, or use any other suitable marks or arrangement. And to still further facilitate putting them together, I use the device shown in lig. 6 and fig. 7, where, upon one only of the sectional parts z, is a hollow or indented projection or shoulder forming a kind of cup d. Into this cup or concave shoulder, d, the point or part e is made to t, and, to put' the sectional parts together, it is' only necessary to place their points e c side by side into this cup al, taking care to keep thecontinuity of the serewfthreadf, which may be done, either by the numbering before mentioned, or any other suitable marks, so that the handle C may be screwed on readily. In manufacturing these mincing knives for market, it is evident tha-t the part 7i, the leg b, and the knife e, `may be made all in one piece, either by swaging or casting; thus rendering tsmanufaeture comparatively cheap, and within reach of all who would use a mincing knife; and, as yit performs much more ivork in the same time than asingle knife or blade, making it desirable for use, particularly in all large establishments, hotels, boarding-houses, &c., While at the sume time itis perfectly easy to keep in order, and is free from all complication usually attending the more expensive mineing machines. The facility with which this knife'l can be'taken apart and put together wouldV operate to its advantage in the mat/ter of their shipment in quantities, as it is thus lcapable of being packed 'in much less space` When taken apart, and is consequently much less liable to breakage in transportation, as the smaller and weaker parts could be packed closer together. The pecnliar'manner in which the knives are grouped in a radial form, renders it both desirable and advantageous for use, as it more nearly conforms to the shape of the bottom of the common wooden mincing bowl than-nay other mincin'g knife in use. If it should be desirable from any oauscfto manufacture the knife with a solid shank, but with knives radiating);` in this way, it might bedone; but in that ease it might be better to have the foot 7s sufficiently elongated to permit the use of two screws in each foot, instead of the rivet o, to facilitate the removal of the blade for the pixrpose of sharpening. y

Having thus described my invention, what I claim as new, yand desir-e to secure by Letters Patent, is-

The sectional stems or Shanks l., with the knives c, in combination with the cylindrical clamp or ring a, and the socket g, substantiallyas herein described, and for the purposevset forth.
