IMPROVEMENT IN CHEESE VATS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, L. C. HAINS, of Bedford in the county of Cuyahoga, and State of Ohio, have invented certain new and useful improvements in Cheese Vats, 820.; and I do hereby declare that the following is a full and complete description of the construction of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a top view of the vat.

Figure 2 is a longitudinal section of the same.

Figure 3 is a detached section to be referred to hereafter.

Like letters of reference refer to like parts in the views.

7 This vat or heater is constructed in two sections, A, B, fig. 2, of which A is the fire-box and B the draught. It will be seen that the bottom of the draught is raised above the bottom of the firebox, and is provided with a fine, 0, in the front end of which is a damper, D; this damper is so hung or adjusted as to drop by its own gravity and close the flue, and is opened in a manner aswill hereafter be described. The top of the flue referred to is not closed the entire length of the draught, but stops at little short, thereby leaving an opening,

E, for apurpose hereafter shown. F is a handle, by which the door of the fire-box is opened. G is a damper across the top of the door, and H is a sliding damper to which reference will he made. The fire, on being built in the box, (immediately under a section of the vat proper, which is made to fit the entire top of thefire-box and draught,) is conducted back through the draught to the exit pipe I, and thus heating the entire vat. In order to 'shut oil" the fire from the vat, the damper D is opened by sliding the damper H forward toward the front of the firebox. As the damper slides it presses down the raised end of the rod (2, to which the damper D is attached, andthereby opens it, and thus allows the fire to pass through the flue to the pipe I. It will be evident that the sliding damper shuts off the fire at the same time. from the section of the vat immediately over thebox, and thus excluding it completely from the direct heat of the fire. Fig. 3 is a. form of damper which may be used in the place of the one in the fine. This damper is mainly like the sliding damper H, the only difi'erence being that this damper is provided with a, disk, J, which, when the damper is in the position of H, the disk will cover the inner end of the line, and thus shut off the draught through it as effectually as would the damper J within the flue. Should it be needful to reduce the heat rapidly so as to cool off the curd, it may be done by throwing open the damper-Gr, and allowing a free current of cold -air to flow into the apparatus between the top of the damper and draught and the under side of the vat; by this means the heat is readily and easily graduated to the wants of the operator.

The advantages attending the use of this apparatus over others for a similar purpose, is the complete control the operator has over the fire, so that he is enabled to graduate the heat as to prevent the milk from burning or becoming too hot, which is hardly possible in many vats or heaters now in use. It is much more simple in its construction than the ordinary heating apparatus; it is cheap, and very convenientin its arrangement, and allows of a large quantity of mill; to be heated at once. This apparatus is equally well adapted for the evaporating of sugar, and for heating large quantities of water, and for all such purposes for which a boiler and furnace are usually applied.

What I claim as my improvement, and desire to secure by Letters Patent, is-

1. The arrangement of a vat heater in sections A Band central flue 0, provided with the damper D, as and for the purpose specified. I

2. The sliding damper H, in combination with the flue C, damper D, and firebox B, as and for the purpose set forth.
