SAMUEL H; COGHRAN, OF EVERETT, MASSACHUSETTS.

COMPOUND TO BE USED lN THE PLACE OF BUTTER FOR COOKING PURPOSES:

SPECIFICATION forming part of'Rei'ssued Letters Patent No. 10,171, dated August 1 .1882.

Original No. 258,992, dated June 6, 1892. Application for reissue filed June 29, 1882. i

To all whom it may cancer-n:

. Be it known that I, SAMUEL H. COGIIRAN, a citizen of the United States, residing at Everett, in the county of Middlesex, and State of Massachusetts, have invented a new and useful Compound to be Used in the Place of Butter and Lard for Cooking Purposes, ot'which the following is a specification.

I take what are known as fcaul and kidney beef suets and trim the same carefully, and then pass the same through a cutter or such process as will soften and prepare the suets foreasy rendering. I then place the same in stearn'jacket kettles, or other kettles to be heated, and subject the mass to heat of about 150 Fahrenheit, and keep the same in con slant agitation until the whole is sufficiently rendered. To purity and give a flavor to the oil,'and also to hasten the settling of the scraps, I introduce during the process of rendering about one three-hundredth part of ground or slippcryelrn bark. After the scraps are settled I then draw off the clear oil thus prepared for use in the compound. I also take refined cotton-seed oil or any equivalent vegetable oil and place the same in steamjacket kettles or other vessels, to be heated, and while the same is being heated I mix into the oil about one-seventieth or one-eightieth part of slippery-elm bark powdered or ground. This serves both to purify the oil and to improve its flavor. I then subject the same to heat of about 190 or 200 Fahrepheit for about one and a half hour, and during the process I cause the mass to be constantly agitated. I then remove the steam from the kettle and leave the oil to corl (on about eight or ten hours, and then draw oil the oil forxuse in the compound. Bcef-stearine is a well-known arlicleol' commerce, and is prepared in the following manner, viz: Take beef-snot and render it in usual way-that is, by cutting the suet fine and heating'the same in renderingkettles at a low temperature until the mass becomes liquefied. When the heat is taken off and the scraps are settlcd draw O f the clear oil into a cooling-tank and allow it to cool'until it has become granulated or thick. Then take a piece of cloth suitable for a folding bag, which, when folded, will be in size about five inches by six inches, or any suitable size for the press, and lay the cloth unfolded upon. the bottom of the press adapted for this use, or lay the unfolded bag upon astand to be removed to the press, and place upon the middle ofithe cloth from one to two pounds of the granulated or thickened oil and fold the ends of the cloth over the same, so when folded the bag inches. side by side upon the bottom of the press. Other similar bags maybe so placed upon these until the press is full. Then bring a gentle pressure at first upon the bags, and gradually thus formed will be about five inches by'six I usually lay five or six similar bags.

increase the pressure until the oleine and margarine constituents of the oil are pressed out through the bags, flowing into vessels to receive the same. There is then left the solid part of the oil-:thesteariue. a clearndriteagglsolid cake. T his is what I call beef-steariney i I then take about sixty-eight parts of the prepared cotton-seed oil and twenty-eight parts l stant agitation all the while until it is cooled 8b to about the consistency of cream. The conipouud may then be drawn off into packages suitable for themarket. The compound thus treated willharden to about the consistency of lard. r

The compound thus'iormed is fiound to be superior to and more economical than butter or lard for all cooking purposes, and this method of purifying and settling the scraps of suets and purifying the oils by means of slipperyelni is new and useful. Slippery-elm as applied also at the same time corrects. the dis agreeable odors arising from the'oils and imparts an agreeable and pleasant odor when-the compound is used.

I am not confined to the exact proportions of the above-described ingredients in the compound, nor am I confined to the exact degrees of heat in treating the same; but I have found the best results as herein set forth.

I disclaim the inventions patented to Henry W. Bradley, of date January 3, 1871, No.

- 11 9.626, and of date October 3, 1871, No.

culinary use and improvement in shortening for culinary uses.

What I claim as my invention, and desire to obtain by Letters Patent, is 1. The described method or process of p'uri Tying and flavoring beef-sue; oil, which eonsists in mixing therewith slippery-elm bark, snbstant-iaiiy in the proportions and in the manner and for the purpose shown and de;

2. The described method or process of puri lying and flavoring cotton-seed oil and its equivalent 011s, which consists in mining therewith slippery-elm barkfln the proportions, subsiantialiy and in ihemanner and for the purpose shown and described.

3. The comhination'of beef-suet oil, cottonseed oil and its equivalents, purified and tie- Volfid as described, with beef-stearine and siigpery elm hark, substantially inthe proportions setforth, and for thepurposes shown and described.
