Letters Patent No. 61,907, dated February 5, 1867.
IMPROVED APPARATUS FOR STIRRING AND COOLING LARD.
To ALL WHOM IT MAY OONGERNz' Be it known that I, GILES B. WILLIAMS, of the city. county, and State of New York, have invented a new and improved Device for Stirring, Heating, and Cooling Lard; and I do hereby.declare that the following is a full, clear, and exact description thereof which will enable those skilled in the art to make and use the same,
reference being had to the accompanying drawings, forming part of this specification, in which- I Figure 1 is a plan or top view of my invention.
Figure 2, a longitudinal vertical section of the same taken in the line I 9:, fig.1.
Similar letters of reference indicate corresponding parts. A
This invention relates to a new and improved device for stirring lard during the process of heating and cooling the same, and it consists in the employment or use of a horizontal screw placed in the lardreceptacle, and arranged in such a manner as to keep the lard in constant motion. The invention also consists in using; in
connection with the screw, a double-walled lard receptacle, through which hot or cold water or steam may be passed for the purpose of heating and cooling the lard.
A represents the lard receptacle, which may'be constructed of wood or metal, and of rectangular or other suitable form. This receptacle is made with double walls, a space, a, being'allowed between with an induction pipe, 6, at the upper part of one end, and an eduetion pipe, b, at the lower part of its opposite end, both of which are shown in fig. 1-. A B is a shaft placed horizontally in the receptacle A, one end passing entirely through one end of the receptacle, and having a crank' or driving-pulley applied or attached toit. The shaft B runs in smiling-boxes in the ends of the receptacle A, and a screw-flange, C, is attached to the shaft, extending its whole length and attached to arms, a, leaving an opening, b at its centre around thes'haft, as shown clearly inboth figures. The periphery of the screw-flange C just cleans the bottom and sides of the receptacle A, and the interior of the receptacle at its lower part may be of semicircular form in its transverse section corresponding in dimensions to the diameter of'the screw-flange G. On turning the screw-shaft B from left to right the lard in the receptacle A will be forced in the direction indicated by arrow 1, and will return undersaid pressure or force through the opening or space 11 around the shaft B, in the direction indicated by arrow 2, and all the particles or molecules of the lard will be well stirred, the lard being moved in a constant .unhroken stream forward and backward within the receptacle. The bottom of thcreceptacle is curved concentrically with the shaft B. The edge of the flange C sweeps the sidesand bottom of the receptacle. The liquid is raised and forced toward one end of the receptacle, along its sides, by rotating the screw, and unites at that end and returns in a continuous stream through the opening between the shaft and flange, whereby a new surface of the liquid'is continually presented to the atmosphere, facilitating its cooling and quickly reducing it to the temperature of the atmosphere, In discharging the liquid it is forced with equal pressure through thedischarge spout regardless of quantity in the receptacle, admitting of regularity in filling cans, pots, or other vessels. The shaft may be made hollow, so that steam or heat may be passed through it, which will assist in preventing. the thickening of the liquid before it is forcedout of the receptacle, and likewise prevent its lodgment' on the shaft. In heat: ing or rendering lard, a flow of warm water or steam is allowed to pass through the space between the double walls of the receptacle; and in cooling thelard, a stream of cold water is allowed to pass throughi The stirring of the lard causes the heat or cold to be rapidly transmitted from molecule to molecule throughout the entire mass, and the work may be performed with a very moderate expenditure of power.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The continuous flnnge C, secured to the shaft B by arms a leaving an openiilg, b between-the flange and shaft, in combination with a receptacle A,'whose bottom is curved concentrically with said shaft, substantially as described for the purpose specified.
' GILES B. WILLIAMS.
