WATER-HEATING APPARATUS.

Specification of Letters Patent.

Application tiled November 8, 1909. Serial No. 526,728.

To all whom t may concern:

Be it known that I, WELLns MoR'rrMER PARTRIDGE, of Marblehead, county of Essex, State of Massachusetts, have invented an Improvement in Water-Heating Apparatus, of which the following is a specification. v

This invention relates to water-heating devices for small boilers and the like, and has for its object to construct a heating-coil of improved form, provided with means for confining the heat in intimate contact therewith, whereby a very efficient apparatus is produced, W struct and install; and the invention also has for its object improvements in the constructionfof the apparatus,l as will be here matter pointed out.

Figure 1 isa vertical section of a waterheating apparatus embodying this invention. F ig. 2 is aplan view of the waterheating apparatus, the top on the cylinder being removed. Fig. 3 is a horizontal section of same taken on the dotted line Fig. 4 is a plan View of the ring which is provided at the base of the Fig. 5 is a modification to be referred to.

construction; a a pipe leading there- 'from to the lower end of a heating-coil, and

a2 a pipe leadingthereto from the upper end of said 'heatlng-coil. The heating-coil is composed of pipe, bent or coiled to form two conical frustums arranged one above the other, with their smaller ends adjoining, as representing the lower conical frustum, and a4 the upper conical rustum. The coil may comprise oneor more pieces of pipe, but is continuous from end to end. The lower end of the lower conical frustum is connected by a coupling a with the pipe a', and the upper conical frustum is connected by a coupling a with the pipe a2. Sald couplings are here shown as quadrangular .inl cross-section to substantially till recesses formed in the castings through which they pass, but they may The heating-coil rests on lugs b extended inwardly from a ring b', which has at lts Said on its under side' lugs b3, adapted to rest upon and be connected with the upper ends of supporting-arms c, any desired number being employed, which are connected at their lower ends to an uprig t post c', rising from a suitable ring also has 1ch is compact and easy to con.

base c2. bell-shaped extension are preferably, but not necessarily, cast in a single piece. The heatlng-coil is contained in a cylindrical case d. Said case is fitted over the ring b and rests'on top of the extension b2 and extends up' to a point above the top ot the coil, and it is open at each end, and at the top has fitted into and upon it a cap al. Sald cap has a flange Z2 which extends down into the case, and a flange d3 which extends over upon the outside of the case, so that the upper edge of the case enters the space formed between the flanges d2 and d3. Said cap is secured tothe case by screws d? or otherwise. Said cap has a center-hole' ai through it of any suitable size. Said case as here shown consists of two concentrically arranged metallic cylinders disposed with a space between them containing insulating or non-,heat conducting material. j

The lower part of the heating-coil or conical frustum a is inclosed by a shield e of frusto-conical form, corresponding to the shape of the portion of the heatingcoil which it inoloses. Said frusto-conical shield extends from the ring b on which it rests to near the upper end of the lower conical trust-um, and it is preferably made to engage the heating-coil, as shown,"'but it may be arranged more or less removed therefrom, if desired. The heating-coil has arranged within it an imperforate shield f of conical form, which extends from the to of the upper conical frustum downward The ring b and lugs thereon and' 'Patented J an.. 7, 1913.

to at or near the lower end of the lower i conical ltrust-um, andsaid shield is placed in the upper conical frustum and preferably supported by it. The shield e, as here shown, is composed of a metallic inner-wall which is covered externally with an insulating or nonheat-conducting material, and .the shield f, as here shown, is composed of a metallic outer-wall which is linedwith insulating or non-hieat-conducting material, and the metallic wallsof said s ields serve as deflectors for the heat. Theheat, passing up. through the lower conical frustum is confined by the .frusto-coni-cal shield'e, thereby heating the lower part of the heat ing-coll, and it then passes out between the convolutions into the case d, at the upper end of-,said'shield e,.and is confined between i the walls of the case and the shield f, thereby heating the upper part of the heating-coll. The imperforate conical shleld f,

L and gas by any suitable means.

when resting in the upper partv of the heating-coil and extended down into the lower plart thereof acts as a deflector to cause the eat to engage all the convolutions of the heating-coil and causes the heat to pass up on the outside of the upper part' of the heating-coil. It will thus be seen that the heat passes upward on the inside of the lower part of the heating-coil and on the outside of the upper part of the heatingcoil. By reason of the conicalformation of the two parts of the heating-coil, when constructed as `here shown, the heat will. directly engage each and every convolution thereof as it passes upward. By making the heating-coil in two conical frustums, as shown, and arranging the shields on the outside of one and on the inside of the other, the water pasing through the heating-coil is vvery quickly heated; f

The coupling a,6 extends through a hole made in the case d and flange d2 on the cap and the coupling a5 extends through a like hole made in 4-the case d and ring b', the shape of the couplings corresponding to the shapes of the holes.

As shown in Fig. l, the heating-coil is arranged above a gas-burner g of any suitable construction, which is located inside of the bell-shaped extension, and which is adjustably supported on the upright post o and adapted to be supplied with mixed 'air In Fig. 5 the heating-coil is arranged in astove-pipe k, which is connected in ordinary manner to a stove or range h, and the heat passes i through it in the same manner as shown, in Fig. l.

A modification of m invention forms the i. subject-matter of a ivisional application, serial No. 622,676, filed April 22, 1911.
