To all whom it concern:

Be it known that I, ROBERT C. HOYT, a citizen of the United States, "residing at Oakland, in the county of Alameda'and State of California, have invented certain new and useful linprovementsin Gas Heaters, of whichthe followin'gis a specification.

My invention relatcsnn' general to'gas heaters of the radiator type, and-has forits primaryobject to provide a'heater of this character embodying several distinctive. fea tures with resultant improvements in effectiveness, such as, greater simplicityin'construction, economy of fuel, ease inligl iting, prewarining the entering air to the radiator, radiating the heat'tl'ii'efiy from the front columnsof' the radiator by retarding the heat units therethrough', and providing for a comparatively cool -fioor surface directly under the radiator.

'llrelireferrd fornroftheheater is illustrated in theacCOmpanying two-sheets of drawings and in which Figure 1 is a View in fr'o'nt elevation of the heater and Figf 2 an end-elevationotit. Fig. 3is a vertical sectional viewfthrough the heater showing clearly the partitioirwall behind the burner. Fig. 4 is "an enlargeddetail view in \efrtical fsectionof 'the lower part of the middle section of the radiator, and Fig. 5 is a similar View of the intermediate sections. v

Referring now to the drawings in detail 2 The letter A'rep'resents the radiator sections which may be made of cast iron, pressed-steel or any other material suitable for the-purpose. These sections are arranged as a series of units properly spaced for heat radiating purposes. Each unit in the'series is practically separate, 'exceptwhere itscylinder-like bases are joined end to end, preferably with male and temalejoints 6, Fig; 3, toprovide an elongated manifold housing 7 'for the ordinary gas-pipe burner 8.

'lheburner is connected to a gas pipe 9 through one end of theh'ousing 7 and the pipe'9, includes a control valve 10 and the customary airrmirling valve 11. p

The housing is divi'ded longitudinally by vertical. partitionsl2 formed as a part'of each radiator section, and the partitions abut end to end, similar to the sections, to make a continuous longitudinal partition wall for the entire length of the housing, dividing the latter into two zones, the burn- .er zone and the exhaust zone.

Theburner 8 isdisposedin front of the pautitionwall '12 and the products'of coinbustion circulateup the front column of the sections and 'down the hack'column into the exhaust zone in back of thepartition 12. The middle section is slightly modified in construction in that it includesan outletflid, fron'r'which theproducts of coi'n'bu'stionfrom all of the' sec'tions exhaust.

Theinside of the front columns of the sections is preferably madewithhaflles 14,

spaced'fin staggeredrelation to one another 7 to make a" tortuous passage for the products 01 combustion and retard them to a deglfee so as to realize the best possible heating effeet. The shoulders between the-sections impart awhirling motion so to s eak, to the products of" combustion as they t'c irchlate through the sections'fto the middlesectioin In thecase of theuiniddle section however,

the circulation continues to and through the outlet 1 without interruption; v

A gain referring to the middle section, I have provided a 'peepdiole 16'with a mica or other transparent medinnr 1,7he1d in place by a ring-{18L "'An opening' 19 is 'alsoprovidcd tor the insertio' of a lllfltCll'tOllgllt the burner.

'lhefimrtition l2in the'hurne'r housing 7 is slightly 'cuiwed" as best shown in Figs; and 5;so as totive'rhangthe burner and directthe products of combustion up the front column of :thesections and against the first baffle therein. a

The direct" contact of the flame ofthe h'u'in'er with the partition 'wall 12 practically makesthe back part ofthe housinga super" heater. and when the products of combustion impinge-against the said "wall" afterthey have n-a'vers'ednie two columns'of the section, they'willbe again heated prior to reaching the outlet 1S, thus the 'outgoing spent-gases are free otmoi'sture whichinsures "an effective chimney draft.

"Having the burner at the base'of the radiator and the" snperhe'ater adjacent 'thereto,

induces conditions ram-able for" a constant chimney draft whether the radiator'is i-n use in adwelling situated ina. valley or 'en 'a hill top. In this type 'otiradiatonif or efficient results; it is HGC'ESSZMWtlYfll; the'hurner be positioned low in order that the heatunits may have a chance to rise vertically before being drawn downwardly, otherwise the chimney draft is sluggish and especially so in low lands,

One of the important features of the heater resides in the construct-ion of the air intake from the floor region below the burner. I have found in practice that by making an opening 20 in the bottom of each section, and covering the same with a prewarming plate 21 that I can get much better results. This plate may be secured to a downwardly projecting flange 22, extending the entire width of the radiator, by screws 23 or the like. The plate should extend under the heater and be spaced from its bottom to permit sufficient air volume to reach the air intake openings 20. The plate should alsobe slanted downwards as best shown in Fig. 5.

The plate 18 will be heated by the burner because of its proximity thereto, and in this way the auxiliary air taken in to support the burner flame will be heated prior to its mixing with the gas and by the interchange of heat just recited, the floor surface below the radiator will be comparatively cool, a feature much desired.

The sections may be secured together in any convenient manner as by rods 20 top and bottom, shown to advantage in Fig. 8.

Having thus illustrated and described my invention in the best form as yet devised by me, what I claim as new and desire tosecure by Letters Patent is the following:

1. A heater of the class described, comprising a series of one-piece radiator sections of loop formation with a burner housing at the base of said sections, a burner therein, a longitudinal partition wall in said housing, said burner being positioned to one side of the partition, one column of each radiator section communicat ing with the housing on the burner side andthe other column communicating with the housing on the opposite side of the par tition, and an outlet in said last-named side, the flame from said burner adapted to impinge on the said partition wall thereby forming a superheater on the other side of said wall.

2. A heater of the class described, comprising aseries of one-piece radiator sections of loop formation with a burner housing at the base of said sections, a burner therein, a longitudinal partition wall in said housing, said burner being positioned to one side of the partition, one column of each radiator section communicating with the housing on the burner side and the other column communicating with the housing on the opposite side of the partition, and an outlet in said last-named side, and an air intake in the housing in front of the burner,

the flame from said burner adapted to impinge on the said partition wall thereby forming a superheater on the other side of said wall.

A heater of the class described, comprising a series of one-piece radiator sections of loop formation with a burner hous ing at the base of said sections, a burner therein a longitudinal partition wall in said housing said burner being positioned to one side of the partition, one column of each radiator section communicating with the housing on the burner side and the other column communicating with the housing on the opposite side of the partition, and an outlet in said last-named side, the said partition wall being disposed tooverhang the burner and the burner positioned against the same, an air intake in the bottom of the housing in front of the burner, and a pre warming plate disposed below said intake and extending transversely across both colums of the radiator sections, the flame from said burner adapted to impinge on the said partition wall thereby forming a superheater on the other side of said wall.

5. In a heater of the class described, a series of radiator sections, a cylindrical housing at the base of said sections, a partition dividing said housing midway longitudinally into a fire chamber and a superheater chamber, a burner in said fire chamber adjacent said partition, and an outlet in the housing on the opposite side of the said partition adapting the products of con bustion fromthe burner to pass through the sections and said superheater chamber before exhausting through said outlet.
