Specification forming part of letters Patent No. 81,743, dated September 1, 1868; reissue No. 5,925, dated June 23, 1874; application filed June 16, 1874.

To all when: itgmag concern lie it known that I, Airos lhioanxar, ot"

,dering Lard and Tallow and other animal matter, and for cris iing or drying; the scrap or refuse thereof; and I do hereby declare the following to he a full, clear, and exact description of my said invention,reference being had to the annexed drawing making part, of this specification, in which- Figure l. is a longitudinal rertical section, and Fig. i. a transverse vertical section, through one form of my apparatus, and ll ig. 3 a vzrtical section through another form hereof, the two tbrnm embracing the sei eral and essential principles myiovention.

My invention, as illustrated in l and. 2, consists of a tightstationary tank, confined in a close stationary chamber, tilled with an atmosphere or heat or cahn-ic in some suitable form and ot' sutiicien't 'temperati'u'e to r der or dry the matter under treatment,

"stirrer, so constructed and arraiieed with refer-- encc thereto, that the material under treat ment may be tin-own over and over while it is being rendered or dried, the apparatus to be so ronstructml, in case or need, that the matter under treatment can be rendered or cooned, he rendered fat; and water, or either of the-m,'drawu of, and the scrap or refase dried or CllSlHFll, without opening the mair holes of the tank so as to make a nuisance; and my said invention consists also of a near bination ot'said tank with a covered or rererberatory furnace, (:(uistrutted to eomzeutrate and retain the heat for the more effectual con- .sumption of the gases and ra aurs developed in the operation, as will be hereinafter more fully described. My intent-ital, as illustrated. in Fig. 3 ot' the drawing, consists of a tight chamber, 0, composed ol' brick or metal, as maybe required. and oi a. tightmelal chamber, lhsrt insideol' the eli:m1li0rL-,in the man- ('1' substantially as shown, and of an open or closed tunic, as the case may require, (shown by. .,)set insidrol' theehaiuber .l. The tank A is divided l'y a. perforated partilion-plate, l), and is titled with a man-hole, 1%, to disrharge the refuse after the rendering or drying is completed.

luthedrawing' the partitioirplate isset about inthe center oi the tank, measuring from top ,to bottom thereof, but it may, of course, be set higher or lower, as the case may require. It should be adjusted, however, with reihrence to the bottom of the tank or drawoft' pipe and reservoir, to leave room for all of the fat or water to drain clear of the scrap or refuse on the plate, The tank is chargedthrough a man-hole made in the top of the chamber B, and this chamber is cooled by opening; the manhole 1 all of the man-holes being titted with the usual mountings to keep them tight. The chamber 0 is made over afurnaec preeisely the same. as in Figs. 1 and 2, the furnace being made the same, and the method of deodorizing or consuming the gases and vapors in thefurnaee is also the same.

This apparatus(litters from that shown by liigs. 1i. and 2, in this: That here the material is rendered or otherwise treated. without being stirred, while in the other it may be kept constantly in, motion or left at rest during part of the process,

in the-original patent granted for this invention there are .variousforms and additions shown in. the drawing,- and described in the specification; but; it does not seem to be necessary to embrace. in this amended specititration all these forms, details, and additions. They merely show some of the forms and methods of application, of which the 'inrention is susceptible; but Figs. I, 2, and 3 ot' the drawing embody the essential-principles oi the invention, and show a practical method of its application, although, perhaps, not the best met-bod which experience may suggest i shall, therefore, omit from this specification and the drawing making part hereof, all the figures oi the old drawing, but these three,
