IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. 176,744, dated May 2, 1876; application filed March 24, 1876.

Toall whom it may concern;

Be it known that I, WILLIs S. GARRIsoN, of Volga City, in the county of Olayton and State vof Iowa, have invented a certain Improvemet in Heating-Stoves, of which the following is a full and clear specification This invention relates to leating-stoves in i which a series of open air` pipes or tubes 'are used, some of then 4being'so disposedand connected with an air-chamber 'as to admit of the distribution of the h'eated air to other apartments, theobject being to utilize to the fullestl extent possible 'all the heat emitted by the fire.`

My improvement consists of a novel combination ofthe air-pipes, air-receiver, and valves for governing the distribution of the heated air, and also in a novel construction of the pipes and some parts of the stove, providing for the ready removal of the former, should they become defective 'from some cause or other; These pipes are of a tapering form, gradually decreasing in size fron .top to bottom, soithat the air which enters from below will have ample room to expand as it becomes heated, and will consequently fiow more freely than if thel pipes were straight. A number of these pipes are arranged vertically around the combustion-chamber, passing through the stove near its side and rear plates; a smaller nunber are disposed horizontally over the combustion-chamber, opening into an airclamber'which is located directly in front of the smoke-pipe. A pipe leading from the top of the stove conducts the heated air to other apartments, the lflow of the air being .regula'ted by means of a damper and register in said pipe. The bottom plate o f the stove has flanges upon its upper surface, around -Wlich the tapering ends of the vertical pipes snugl y fit a In the annexed drawing,-Figure l is a longitudinal section of my improved heatingstove. Fig. 2 is a horizontalsection thereof. Fig. 3 is a vertical section through the airreceiver.

The-same letters of reference are used in all i i. the figures in the designation of identica-l parts. I v

A' refers to-the bottom plate of the stove A. This plate has a series of fianged apertures, a, near its sides and rear end, the flanges a' projecting a short distance above its upper surface. Around these `flanges the lower tapering ends of the vertical pipesB fit snugly, while the rims b ontheir upper ends rest on the top of the stove. The front of the stove has a number of perforations .near its top for the reception of pipes C, which conduct air to the chamber D. These pipes -are also tapering in form and removable, like pipes B but their inner ends open directly'into the airchamber, while beads or flanges o, formed upon them near these ends, rest against the outer surface of said chamber. As the pipes E, leading from the bottom of the stove to the' air-receiver, must of necessity be removable from below,they are made straight, their upper ends fitting snugly around flanges d' of the flanged apertures d in the bottom plate of the' struction may be changed, according as it is V located in a coal or a wood stove. The vpipe G dis'tributes the heated air from the chamber D to other apartments, if the damper g be turned 'up. lf the damper is down, as in Fig. l, the air will return into the same room through the register gl. p

lThe drawingsv illustrate a wood-stove; bu't my improvement is applicable toall sorts of stoves and furnaces, whether the fuel burned in ``them be wood or 'coal.

The facility with which the pipes may be removed for repair, or replaced by new ones, and the means afforded by virtue of thein peculiar construction for the ready flow of the air, are advantages which make my improved heater superior to all others now in use.

What I claim as ny invention, and desire to secure by Letters Patent, is-l 1; In a stove, the combination, substantially as specified, of the air-heating pipes B C E,

the air-receiver D, the air-eduction pipe G, the damper "g, and the register lg'.

2. The' tapering air-heating pipes G, havin-g name to this speoification in the presence of a flang'e at the outer end, and a head, c, near two subscribing witnesses. the other end, in combination with the air-l v I i I receiver D and the body of the stove, the WILLIS S. GARRISON. pipes being fitted in the body of the stove Witnesses: and the air-receiver, substantially as specified. H. H. PIERSOL,

In testimony Whereof I have signed my J. D. BRODIE.
