UNITED STATES PATENT CHESTER OOMSTOCK, OF NEW CANAAN, UONNEOTIGUT.

IMPRovEMENI in s'rEAM-.HEATER'RADIAi-'oea Specification forming part of Letters Patent No. 159,155, dated January 26, 1875 application filed I December 10, 1874.

To `all whom it 'may concern:

Be it known that LCHESTER GoMsTocK, of New Uanaan, in the `county-of Fairfield and State of Connecticut, have invented a new and Improved Corrugated Heat-Radiator, ot' -which thefollowing is a specification:

Figure 1 is a vertical longitudinal section of my improved corrugated heat-radiator; Fig. 2, a vertical transverse section of the saine; Fig. 3, a horizontal section thereof; and Fig. 4, a horizontal section, on an enlarged scale, of onelend ofthe same.

Similar letters of reference indicate corresponding 'parts in all the iigures. K

- This invention relates to a new radiator, to be usedfor hot-water or steam heating apparat-us; and consists .in making the radiator with-sides ot' corrugated sheet metal, and ina peculiar way of securing this corrugated metal in the top'and bottom plates of the radiator, all as hereinafter more fully dcscr bed.

The l'tter A in Ythe drawing represents the bottom, plate for base-,plateot' the radiator,

made of cast-iron or othersuitable inaterial,

` B is the body of the radiator, and C the top or head plate thereof, which is also made of east-iron or other suitable material. The body of the radiator is formed of corrugated sheet metal, as is clearly represented in Fig. The inner faces of the plates A and U are provided with sinuous grooves to receive the edges of the corrugated body B ot' sheet metal. The grooves in the plates A and U are wider than the metal of the body B is thick, and are also, by preference, made flaring, as clearly indicated, in Fig. 2,I so that the metal may be slightly bont outward therein, and so, also, that a packing-plate, a., of rubber o r other substance, may be placed in each groove outside of B, and held in place by means of' a metal plate', b, which is screwed down upon the rubber or other packing, all as indicated in Figs. 2 land 3. 1n this manner a steamtight joint is produced in a simple manner. The metal b has also an undulating form, as clearly indicated in Fig. 3, so that it may properly conform to the outline ot the cori-u.- gated body B. In order to keep thelopposite sides of the body B of this 'corrugated radiator from springing' apart or coming too close together, l interpose short tubes d between them, and pass bolts c through these tubes, and through the body, such bolts drawing the opposite sides of the radiatortogether, while the tubes hold them the requisite distance apart. 'lhe tubes and bolts together serve thus to properly brace the whole body oi the radiator in two directions. vertically, the radiator 1s braced by incans ot' bolts or rods j',

which connect thc plates A and U, as clearly -shown in lflg. 1.

In constructing a radiator of the kind de;

scribed it will usually be found impracticable to make its body Ilot* one single length oi' sheet metal. As a general thing, itwwiil be more convenient to make it ot' two pieces ot' sheet metal, which moet at the ends ot the radiator, as in Fig. 3; and in order 4to properly join these pieces ot' sheet metal I may either lap the same together and solder the joints, or v[ may use a'joint ot' the kind more fully illustrated in Fig. 4-that is to say, l place in the radiator, near to the `end ot the saine, a V-shapcd vertical rod, 17, with its hollow part toward the shcctanetal body B, aml bend the ends of the two sheets into the hollow part of the rod g. I then place a packing, h, ot' rubber or other material, into the hollow of the V, but outside of the plate B, and finally apply a T-shaped plate, i, against suoli packing, crowding the same 'against the outside ot' the pla-tes l5, the central wedge-shaped part, t', entering into the hollow ot" g, and compressing the packing, in the lnanner clearlyindicated in Fig. 4. Small bolts j serve to "conconnect thc V-rod g with the outer plate z', and tohold the parts ill proper connection.

As I am aware that corrugated sheet metal has been previously used on steam-generators and other articles, but that before my invention' steam radiators havin g a corrugated body, and havingthe topand bottom plates continuously giooved for the reception of such cor- Vruga-ted body, have no 'been known,

I claim as my invention- 1. Av steam heating-uitbater composed of' the bottom plate, A, corrugated sheet-metal body B, and top plate, U, the bottom and top plate having each a continuous sinuous `groove for the reception ot','the corrugated body B, and all connected and combined substantially as herein shown and described.

2. The siuuous continuous packing a and corrugated sheet-metal body Bof the heate siuuous continuous fastening-plate b, eolnradiator, substantially as and for the pugpose hined with the grooved end plate, A, and the described. corrugated shew-metal bodyB,of the heab-ra- CHESTER COMSTOCK. diator, substantially as specified.
