To all w/wm t may concern:

Be it known that I, PETER C. FoRREsTER,

a citizen of the United States, residing at Tacoma, in the county of Pierce and State of IVashington, have invented a certain new and useful Improvement in Lime-Hydrating Machines, of which the following is a speci- F iication.

My invention relates to apparatus for hydrating lime and for the handling of the prodprocess, and has for i manner. For example, I have shown two water-pipes E E, having the perforations E in their under sides, this arrangement securinO an even distribution of the water over the lime in the pan.

In the bottom of the chamber is a trough containing a screw conveyer F on the shaft, on which is the pulley F2, driven by a belt F3 from any desired source of power. The conveyer discharges into a cylindrical uct of `such hydrating screen G, through which the 'finer product is its object to provide new and improved sifted into a trough G. The larger lumps devices and constructions in apparatus of this character.

he invention is illustrated in the accompanying drawings, wherein` igure l is a horizontal sectional view through the top of the hydrating-chamber, Fig. 2, a vertical section on line 2 2 of Fig. l and ig. 3, a vertical section on line 3 3 of Fig. l.

Like letters of reference indicate like parts in. all the drawings. y

The apparatus consists of a boX or chamber, with suitable means for holding the lime and supplying 'water thereto, together with new and improved devices for sifting and conveying the product of such hydration.

A represents the boX forming the hydrating-chamber, provided at the top with the are carried out into the receptacle II by means of the spokes J J, formed on a collar J, pinned to the end of the conveyer-shaft.

I wish it to be understood that I do not desire to be limited to the exact details shown and described, for obvious modifications will occur to any person skilled in the art.

he use and operation of my invention relating to the hydrating of lime is as follows: The doors of the hydrating-chamber being in two pairs are open upwardly and folded toget er in groups of two, so as to leave the largest possible amount of open space. The hydrating-pan will be suspended in a hori- Zontal position, resting at one end on the cross-bar and at the other being supported by the chains. The lime will then be spread over the pan, and the doors will be c losed.

This steam is discharged fold together, this arrangement affording the through a number of small holes up into the est possible amount of open space. chamber and passes around and fills the Within the chamber' is a hydrating-pan B, chamber and assists in carrying on the prochaving two bottoms B B2, between which is ess of hydrating. the space B3. The pan is arranged to tilt on ter isfurnished from the tank to the water a suitable axis. For example, I have shown pipe or sprinkler, which is mounted above the pan mounted by means of straps B4 on a the pan either so that it may swing back and pipe C, the pipe extending across the hydratforth or provided with holes properly graduing-chamber at one side of the center of the ated, so as to give a comparatively uniform pan. The short end of the pan rests upon distribution of the water over the surface of the cross-beam B5, the long end being susthe lime. When the process of hydrating pended by the chains D D, attached to the has been carried out, the crank can be operwindlass D, which may be conveniently ated to lower the chains and release the one manipulated by the handle D2, which is held i end of the pan and permit it to assume the in position by the pin D3. The pipe C is f inclined position, (shown in dotted lines,) provided with perforations C, opening into whereupon its contents, consisting of hythe space B3. Steam or other hot fluid is drated lime, will pass down into the transintroduced into the space B3. Preferably I verse trough at one end of the collector. use steam, and this heats the pan and also Here the conveyer conveys it out into the prevents the wooden part from burning. sifting-chamber at one side of the hydratingater may be supplied in any desired chamber. The outside of this chamber is A suitable supply of wation of a hydrating-chamber, with a tilting I the fine stuff passes into a suitable receptacle below. The ou ter vertical side of this siftingchamber is open, and the heavy lumps of material carried around by the spokes on the conveyer-shaft, which are not sifted through the exterior screen, will be thrown outwardly and fall into the receptacle for large lumps.

I claimd 1. In hydrating apparatus, the combination of a hydrating-chamber, with a tilting pan, means for supplying water to the material in the pan, and a conveying device for conveying the hydrated products from the chamber.

2. In hydrating apparatus, the combinapan, means for supplying water to the material in the pan, a trough below one end of said pan, and a conveyer in said trough,

3. In hydrating apparatus, the combination of a hydrating-chamber, with a tilting pan mounted on an axis to one side of its center line, means for tilting and raising said pan, a trough in the chamber into which said pan discharges when tilted, and a conveyer in said trough.

4. In hydrating apparatus, the combination of a hydrating-chamber, with a tilting pan mounted on an aXis to one side of its center line, a windlass device for supporting the long end of the pan, a trough in the chamber l 5. In hydrating apparatus, the combination of a hydrating-chamber, with a pan in said chamber, a screw conveyer to convey the material from the chamber, and a screening-chamber to receive the material from the conveyer.

6. In hydrating apparatus, the combination of a hydrating-chamber, with a pan in said chamber, a screw conveyer to convey the material from the chamber, a cylindrical screening-chamber to receive the material from the conveyer, and rotating spokes in the screening-chamber.

7. In hydrating apparatus, the combination of a hydrating-chamber, with a pan having double bottoms, the upper one being perforate and a pipe to discharge ahot Huid into the space between the bottoms of the S. In hydrating apparatus, the combination of a hydrating-chamber, with a pan having a double bottom, and a steam-pipe on which the pan is mounted so as to tilt thereon, said steam-pipe being perforated so as to discharge steam between the bottoms of the pan.

It is hereby eertied that in Letters Patent No. 848,358, granted March 26, 1907, upon the application of Peter C. Forrester, of Taeoma,Washington,for an improvement in Lime-Hydrating Maehin.es,7 an error occurs in the printed specification requiring` correction, as. follows: In line 51, page 2, the word perforate should read imperfomzfe; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the oase in the Pat-ent Oiee.
