HOG-SCALDIN G TANK.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, GILBERT J. FINGER- soN, a citizen of the United States, residing at Murdock, in the county of Swift, State of Minnesota, have invented certain new and useful Improvements in Hog-Scalding Tanks; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to hog scalding tanks and has for an object to provide a novel furnace into which a semi-cylindrical scalding tank is inserted, the tank terminating short of the rear end wall of the furnace so that the sides, bottom and rear end of the tank are exposed in their entirety to the direct action of the heat, this construction serving to maintain the water at a boiling temperature with a minimum expenditure of fuel. V

A. further object of the invention is to provide the semi-cylindrical tank with a hinged skeleton rack for supporting the carcass, the rack being formed of spaced downwardly bowed bars which conform snugly to the inner contour of the tank and facilitate the carcass being completely immersed in a minimum amount of water.

A still further object of the invention is to provide novel means for rocking the hinged rack out of the water to facilitate rolling the carcass on to the scraping table.

With the above objects in view the invention consists ofcertain novel details of'construct-ion and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made within the scope of the appended claim.

In the accompanying drawing forming part of this specification :F igure 1 is a side elevation of the device. Fig. 2 is a front elevation of the device. Fig. 3 is a plan view of the device. Fig. 4: is a longitudinal section taken on the line 44l Fig. 3. Fig. 5 is a cross section taken on the line 55 Fig. 3. Fig. 6 is a fragmentary view in elevation showing the rack operating handle in the position to hold the rack elevated. v

Referring now to the drawing in which like characters of reference designate similar parts, 10 designates a substantially oblong .furnace having the forward end prorided with a depending extension 11 forming a fire box which is internally equipped with a grate l2, access to the grate being facilitated through the instrumentality of a hinge door 18, and access to the ash box below the grate being facilitated through the instrumentality of a hinge door 14.

Arranged within the furnace is a semicylindrical tank 15, the tank being less in length than the furnace and extending from the front wall to nearly the rear wall of the furnace. A cover plate 16 carried upon the top edges of the furnace forms a closure for the space between the rear end of the tank and rear end of the furnace. The rounded wall of the tank and also the rear end wall of the tank is exposed to the direct action of the heat which passes from the tire box rearwardly along the tank thence upwardly along the rear end of the tank, finally escaping through a flue 17 carried by the cover plate 16. This great heating sur face of the tank being exposed to the direct action of the heat serves to maintain the water at a boiling temperature With a minimum expenditure of fuel.

Arranged Within the tank is a skeleton rack for supporting the carcass, the rack comprising a plurality of spaced clownwardly bowed bars 18 which are connected Patented July 28, 1914. 7 Application filed June 8, 1912. Serial No. 702,448.

at their ends, by longitudinal bars 19, this rack being adapted to conform snugly to the contour of the inner face of the semi-cylindrical tank. One of the longitudinal bars is hingedly secured to the top edge of thefurnace through theinstrumentality of a pair of hinges 20, and the other longitudinalbar is equipped with an upstanding lug 21 to which a chain 22 is attached. A lever 23 is pivoted intermediate the ends to the upper ends of an upstanding bar 24 which is secured to the side of the furnace, one end of the lever being connected to the chain 22. By virtue of theskeleton rack conforming snugly to the contour of the semi-cylindrical tank, the carcass may be completely inimersed in a minimum amount of water. By virtue of they rack being hinged to the tank on one side, and being connected to the operating lever on the other side, the rack may be rocked gently on its hinges by manipulating the lever, to splash the boiling water gently over the carcass for facilitating the loosening of the bristles.

A table top 25 is secured to the furnace at the top edge thereof which carries the rack hinges, the free end of the table being supported by spaced legs 26 arranged at the corners of the table top. The table top receives the carcass and supports the same while the bristles are being scraped ed, the carcass being elevated to the table by nianipulation of the operating lever to swing the rack. up on its hinges, the rackbeing locked in this position by engaging the handle of the lever with a hook 27 carried on the side of the furnace.

What is claimed, is

A hog scalding device including a semicylindrical tank, a skeleton carcass supporting rack within said tank including a plurality of spaced downwardly bowed cross saidtank opposite from said hinges and operatively connected to the other of said longitudinal bars for rocking said rack up out of said tank on said hinges.

In testimony whereof, I affix my signature, in presence of two witnesses.
