Application and August 21, 1923. Serial 'N'o. 658,607.

To all whom-it may concern:

Be it known that I, FRANK J. SMITH, a citizen of the United States, residing at Dodge City, in the county of Ford and State of Kansas, have invented new and useful Improvements in Hog-Scalding Apparatus, of which the following is a speci fication.

The present invention has for its "purpose the provision of a tank for disposition over a trench in'which a fire may be built for heating water in the tank, there being a sling operably mounted upon a Windlass supported upon the tank for transmittinga hog over and lowering the same in the tank of scalding water, subsequently to which the hog may be removed and placed upon a table (which also constitutes a slide) where the hog may be properly butchered.

In providing a device of this design and construction, it is theaim to facilitate the scalding and butchering of hogs, the table which is hinged to the side of the tank being so mounted and constructed that it may be disposed upon an incline whereby the hog may be drawn upwardly on the slide by Y the Windlass and then lowered into the tank.

. It is to be understood that the particulars herein given are in no Way limitative and that, while still keeping'within the scope of the invention, any desired modifications of detail and desired proportions may be made in the apparatus accordng to the cir cumstances.

The invention comprises further features and combinations of parts to be hereinafter set forth, shown in the drawings and claimed.

In the drawings:

Figure 1 is a view'in side'elevation of the improved apparatus constructed in accordance with the invention, showing :the table upon an incline and acting as a'slide, the sling being disposed upon the slide with a hog in dotted lines wrapped in the sling.

Figure 2 is :a transverse vertical sectional view on line 2'2 of Figure 1, but showing the sling with the hog therein .as having been drawn to a position over the tank ready to be lowered.

F igure 3 is a fragmentary perspective view of one corner of the tank showing the slide or table as having been disposed in ahorizontal position and on which the sling may rest until thescalded hog is removed therefrom, showing the barfor holding the slide or table in such position.

Figure 4 is an enlarged detail view of the ratchet mechanism for holding the shaft of the Windlass in a position with the sling hoisted.

Figure 5 is a plan view of the sling opened up.

Referring to the drawings, 1 designates a tank which may be of any suitable shape, preferably rectangular, and of any suitable construction, preferably a. wooden interior with a metallic exterior. In using the hog scalding apparatus, a suitable trench of proper size is excavated in the ground and over the trench 2 the tank may be supported.

A fire may be built in the trench, there being suflicient room at each end of the tank to permit the escape of the smoke. The water in the tank is heated by the fire to a boiling point for the purpose of scalding hogs to be lowered in the tank one by one.

Rising from the ends of the tank are standards 3 in bearings of the upper ends of which a Windlass shaft 4 is mounted. One end of the shaft 4 is supplied with a hand wheel 5 whereby the shaft may berotated. Also carried by the shaft is a ratchet 6, there being a spring tensioned pawl 7 mounted upon one of the standards for cooperation with the ratchet wheel for the purpose of holding the shaft in different adjusted revoluble positions. A rod or cable 8 is attached to one end of the spring tensioncd pawl for the purpose of disengaging the pawl. from the: ratchet in order to release the shaft to allow the hog to be lowered into the scalding water in the tank.

A suitable sling including hoisting chains :9 is provided. The hoisting chains 9 are attached to the Windlass shaft and are adaptplied and their ends have suitable rings 16 through which the rods 11 and 12 pass. The transverse chains 15 are interconnected with the longitudinal chains 14, thereby not only preventing displacement, of the various chains relative to each other but also forming a basketlike sling in which the hog may be placed for, scalding in the tank. The

extremities of the hoisting chains at a location beyond the longitudinal rod 12 terminate in snap hooks 17 which,-after placing a hog in the basketlike sling, may be snapped into engagement with the hoisting chains at a location a little beyond the rod 11, that is, after folding the sling longitudinally over the hog. i A slide 18, which also constitutes a table, ishingedly connected at 19 to one of the longitudinal sides of the tank. This slide or table comprises the longitudinal and transverse slats, the transverse slats acting as braces for the longitudinal slats. Hingedly connected to the slide or table, as at 20, is a support 21 which comprises the legs 22 and the transverse bars 23. The latter are secured to the legs, acting as reinforce- Inents therefor, especially when the support is disposed perpendicularly to hold the table in a horizontal position. Obviously, the upper ends of the legs abut the under surfaces of the transverse bars of the table in order to insure preventing the support from collapsing outwardly. When the table is to be used as a slide,'the support may be collapsed under the table in the direction of the tank. lV hen the support is so folded and the table allowed to be tilted on an in clination from the side of the tank, the outer edge of the table will rest upon the ground. When the table is in such position, the sling may be opened up and rested upon the slide, in which case the hog may be rolled upon the sling, the sling folded and the snap hooks 17 connected to the hoisting chains. An operator may impart movement to the Windlass shaft, winding the chains 9 thereon, pulling the sling along the slide and then hoisting it to a position over the center of the open top of the tank. After so disposing the sling with the hog therein, the hog may then be lowered into the scalding water.

After properly scalding the hog, the windlass shaft is reversed in its movement, the sling hoisted and then by a suitable second hoisting apparatus, the sling with the scalded hog therein may be swung to one side into position over the table. lVhen the second hoist is operated to swing the sling to one side over the table, the rod which is connected to. the pawl may be pulled to disengage the pawl from the ratchet to permit the indlass shaft to allow the hoisting cables to 'unwind. However, before pulling the sling to one side, the support which is hinged to the under portion'of the slide is first disposed in a perpendicular position to hold the table horizontally. In this position, the table may then receive the sling. After the sling has been moved or swung to one side over the table, the second hoist permits the sling to lower on the table, after which the sling is opened and extracted from under the hog, whereupon the hog may be butchered in the usual manner on the table.

The second hoist comprises a rotating or rocking rod, 30 mounted in hearings on one end of the trough adjacent one corner thereof and is provided with a lateral arm or rod 31 which is braced or reinforced by a'rod 32. A suitable hoisting cable 33 is connected to the end of the arm and cooperates with pulleys 34, whereby one pulley (which carries a hook 35) may be raised or lowered for the purpose of hoisting and lowering the hog. The cable 33 passes over another pulley 36 and has its extremity terminating near a handle 37 which is carried by the rod 30 for rocking the rod for the purpose of swinging the arm over the center of the trough or over the center of the table. After the sling has been hoisted with the hog therein, the hook 35 may engage with the sling and by releasing the pawl, the chains may be let out from the shaft 4 and the sling swung to one side over the center of the table by rocking the rod 30.

When the table is disposed in a horizontal position, a brace bar 24, which is pivoted to one end of the tank, is connected to one end of one of the longitudinal bars of the table support, there being a notch 25 in the bar 24: to straddle or receive the end of the bar of the support. When the sling is hoisted from the tank subsequently to scalding a hog, it is raised sufliciently to permit a plurality of supporting bars 26 to be disposed transversely of the tank, engaging with the upper edges of the longitudinal sides thereof. The Windlass shaft is partially released, allowing the sling and the hog to rest upon these bars. The rod connected to the pawl is fixed so as to retain the pawl out of engagement with the ratchet, in which case the sling may then be drawn to one side so that it can be positioned upon the table.

The invention having been set forth, what is claimed is:

1. A hoisting sling for a hog scalding apparatus comprising a pair of horizontal longitudinal rods, hoisting chains connectingthe ends of the rods, longitudinaland transverse interconnecting chains, the trans verse chains being connected to the rods and V tank for the reception of scalding Water, a ing a-ndvcrane mechanism for cooperating Windlass mechanism including a shaft supwith the sling to swing it to one side over ported on the tank, a hoisting sling operathe center of the table.
