ISAAC D. SMEAD, OF TOLEDO', OHIO.

VAU LT-H E ATER.

SPECIFICATION forming part 'of 'Letters I Patent No. 426,551, dated April 29, 1890.

vApplication nea July 12.51889.

lnace located at the opposite end ormonth of To ctZ -l zoll/m, lit 771,0@concern.- Be itknown that I, ISAAC D. SMEAD, of To lede, 1n the county ot Lucas andState of Ohio, have invented certain new'and use Iul Improvements in VanltHeat ers, of which' lie ,.,4

following is aspeciiication.

My present invention relates to heaters for use in eonnectionwith the desiccating or dry closets for which various patents have hereto'- fore .been granted to me', land the invention consists 'in the construction of the heater by which it is specially adapted for use in conneetion` with the vaults of said closets, as hereinafter more fully described;

Figure 1 is a longitudinal vertical section through one of the dry closets with my heater shown in position ready for use. Fig.' 2 is-an enlarged centralvertical seetionottheheater fon the line :c Jr of Fig. 3, and Fig. 3 is afi-ont view of the heater in position.

The object of my present invention is to produce .a cheap,siinple, and effective heater that can be readily adapted to and used in connection with these desiccating or dryclosets, and fwhich, when applied as shown, will greatly increase the desiccating operation of the closet, and also increase the draft of air through the-vault, and consequently a more thorough ventilation of the rooms from which the air is drawn to thevault and 'insure a positive draft or current of the air in the direction desired,rand prevent any tendency to a reversal of the current.

In order to a complete understanding ot' the Inode of operation of the invention, reference is made to Fig. 1,'in which D and D repre-A sent the vault of a dry closet made. on my plan, there being a" transverse partition or fioor C extending the whole length of the vault, thus dividing it into anupper duct D and a lower duct D', as more fully described injmy patent, N 0,363,971, to which reference is hereby made for particulars. As shown by the arrows in Fig. l, the air is drawn from the rooms above down into an, airfgathering room A, from whence it passes through the vault into a vent tine or shaft E, which extends above the roof ofthe building.

Heretofore it has been customary' to locate a small heater in the bottom of the Ventshaft .E to create a draft, and in my patent, No. 337,263, I showed such a heater or sm'all fur? sean No. 317,294. N6 man.)

the vault, with its smoke-pipe 'connected with the-lower duct D', and that at its opposite end connectedivith a smoke-flue separate and distinct from vthe vent-shaft E. I now construct `my heater for these closets, as shown more clearly in Figs. l and 2, it being made in the-forni of an open grate. The

'back' I-I with about. one-half of thebottoin and the ends are made solid, and preferably east in a single piece. The front. part G eonsists of a plate cast in the forni of the ordinary gratc-bars\\-'hicl'1 extend down the front and about half-way backward across the' bottoin, as shown in Figs. l and 3. It has a top plate F, which extends from end toend across Athe. top, and which is provided with a proiectionror flange o te iit against the partition C, whieh'is usually made ofl brick-work,

supported on metal bars. extends' up towithiu a few inches of the top plate F and is curved backward' at its upper edge, thereby iorininga nai-row, throat T, which entendsentirely across the top, as shown in Figs. and 3, the object being to cause the smoke and heat to pass from the grat-e in a sheet as wide as the vault, or practically so, thus spreading it out laterally the full width ot the partition, so as to heat and dry all parts of it as uniforinlyas possible.

The grate-body as a whole is made with its downward, the object being when it isset in The back plate llposition to leave' a narrow space between its ends and the side Walls for the entrance of air into the duet DT, said spaces being indicated by the letters J J Ain Fig. 3.

. lfVit-h the heater of the kind shown in my patent, No. 387,263, it had necessarily to be set some little distance from the mouth of fthe duct D', and the heat arisingtherefrom had a tendency to rarefy -the air in the gathering-room, thereby tending 'to reverse the current, and hence ,it was necessary to set it within the vault proper, as there shown, and

that rendered it impossible to utilize the full .extent of the closet, making, as shown in said patent, the number of seats at least one less. In order to overeome'this ditlicnlty, I provide the grate or heater'in this instance with a hood I, constructed as shown in Fig-2, to prevent the radiation of theheat into the air rooin or inlet A. It consists of a frame provided with an inner wall a and an outerwall a of sheet metal, these walls being separat-ed by an open space severa-l inchesin depth or thickness, this space being closedat its ends,

. but open at front and rear, thereby 'forming a channel through `which the air can pass freely, as indicated by the arrows'in As there shown, the outer wall a of this hood is considerably shorter than the inner one at its lower end, thereby leaving an opening for the free entrance of the air, even when the blower or hood is entirely closed. This hood thus constructed 's hinged tothe top plate F, so it can be 1L ised or lowered at will to regulate the '(lratt, put on fuel, dsc., as indicated in Fig, 2, and itis provided with means for adjusting and holding it at any desired position, as shown in Fig. 3, in which a notched bar c is shown pivoted to one end and ar ranged to engage with a pin e, set in the side wall. Its ordinary position, when the heater is in use, is with its lower edge raised about an inc h from the li'oor to admit sufficient air to keep the lire burning. It will readily be seen that the current of air passing through this hood will absorb and carry along with it the heat radiated from its inner wall a, thus keeping its outer wall a comparatively cool,-

and that by this means the radiation ot heat from the heater backward into the air-.room A is eitectually prevented. Another advantage ot this arrangement is that the heated air 1' assing through the hood is delivered into the upper duct I), thus increasing the desiccating operation therein.

By the use ol this heater and locating itat. the mouth ot the vault, as shown, I avoid the lossot the use ot anyportiouot theeloset, and what is tar more important, all the heat is delivered directly into the vault, the main portion of it being delivered into the lower duct D', where it heats the partition or floor C, upon which the deposits rest, and which, with any fluid inatterthere may be, are therefore much more rapidly dried up. 'lh'is heat in this way also secures a strong dratt through the vault, and also prevents any tendency to a reversal of the current.

In Iaient No. 387,263 l4 connected the duct.

1) with a smoke-flue distinct from the ventshatt E; but in this case I dispense with the 'separate smoke-flue and permit the smoke,

gases, dsc., to pass out the vent-liuc with the foul air from the building, and this also increases to sonic extent the draft ot the tiu'e and the ventilation of the rooms from which the air is drawn.

I ain aware that a blower Ier a grate has Fig. 2.

been made with double walls and with dampers arranged to'conduct air direct to the fire or through the spacetinto the chimney above the tire at will; also, that a furnace-door has been made with double walls to convey air to the fire, and that a grate or open stove has been made with a case at its sides, said case having holes for the ingress and egress of air to warni a rooln, and also that aprivy-box has been patented showing a grate attached for drying and burning the contents oi' said box, and I do not claim either of these; but,

Having thus fully described my invention and the manner of using the saine, what I claim isl l. A vault-heater fordry closets, consisting` of the oblong body Il, grate G, and top plate F, with the elongated throat T at the top ot the rear side and having the double-walled hood I atl its front, substantially as and for the purpose set forth.

2. In combination with the vault of a dry closet having two air-ducts, one above the other, a vault-heater, substantially such as described, said heater being so located as to deliver the heat generated therein directly into the lower duct, substantially 21s shown and described.

3. rlhe combination, in a dry closet, of a vault composed of two horizontal ducts, one over the other, a heater, substantially such as described, located ,in the mouth ot the lower duct, and a hood interposed between said heater and the foul-air roonx or inlet, the combination and arrangement being substantially as herein shown and described. l

ivl. In combination with the vault of a dry closet having two horizontal ducts, one over the other, a heater arranged to .deliver its heat and smoke into the lower duct, and a double-walledhood located in front of said heater .and arranged to convey a current of air from the foul-air rooln or inlet into the upper duct, substantially as and for the purpose set forth.

5. The combination of a vault fora dry closet, adapted to have a current of ail-passed through it from end to end, aheater located at, the end at which the air enters said vault, and a hood or screenarranged in front of said heater orl between it and the inowing IOO
