UNITED STATES PATENT OFFICE.

JOHN P. HOPPERT, OF BALTIMORE, MARYLAND.

PORTABLE H EATER.

SPECIFICATION forming part of Letters Patent No. 613,514, dated November 1, 1898.

Application filed March 9, 1898.

To otZZ whom it may concern.- Y

- Be it known that l, JOHN P. HOPPERT, resid-V ing in the city of Baltimore and State of Maryland,have invented a-new and Improved Portable Heater, of which the following is a speciication.

ical construction which can be readily set inposition in the ash-pit or lire-pot of the stove and which will with an economical supply of gas effectively serve to quickly heat the Water-back to generate hot water.

The invention consists in a heating device embodying the peculiar combination and novel arrangement of parts, such as will be rst described in detail and then be specifically pointed outrin the appended claim, reference being had to the accompanying drawings, in Which- Figure 1 illustrates my invention as in use. Fig. 2 is a plan view of my improved heater, parts being in section. Y

In the practical construction my improve ment comprises a feed-pipe which consists of a number of sections 1, having ends la, joined by T-cou plin gs 2, the number 0E such sections and couplings depending on the size or'the length of the fire-pot of the range or Waterback to be heated, it being obvious that the number of such sections may be readily increased or decreased, the last or end section having a closure 3 in the nature of a T, which in practice is secured to the end section and adjusted at right angles to the length of the feed-pipe, so as to form a rest or support to hold the burner in a vertical position when the same is held in the ash-pit at a point beneath the water-back, as shown in Fig. l. The first or front section l connects With the angle-union 5, to Which is joined a nipple 4, which in the practical application of the in- Serial No. 673,218. (No model.)

vention extends outside the ash-pit and receives the end of the flexible supply-pipe 6, which in turn connects with the gas-jet.

To each of the T-couplings 2 is secured a lateral 7, having its end threaded at 7a and terminating in cone-discharges, having each a pin-oriice 7b for the escape of the gas. To the conical end of each lateral 7 is detachably secured a burner-section, which consists of a hollow cone-shaped mixing-tube 8, largest at its outer end and smallest at its point of connection with the lateral 7 onto the threaded end of which it is fitted. At a point over the discharge of the lateral 7 the burner-sections 8 have opposing circular openings Si, facing lengthwise of the heater, through which the air passes into the burner, it being understood that by contracting vthe burner at the openings Sit the air is caused to more readily commingle with the gas asit passes from the lateral 7 in pin-jets.

So far as described it will be readily seen that by placing the device on the ash-pit and holding it so the ends of the burners will discharge against the lower edge of the waterback and turning on the gas-supply to the ylaterals and igniting it at the pin-jets the air as it is drawn into the heaters through the openings 8fL is consumed with the gas in such a manner as to generate more heat with but a minimum amount of gas consumption and the ame discharged directly against the lower part of the Water-heater, thereby concentrating the heat volume at the point to obtain the very best results. Furthermore, by making the closure end 3 adjustable the same can be readily drawn in line with the tubes 8, andwhen in such position theheater can be laid iiat on the grate, asv indicated in dotted lines in Fig. 1. When in this position, it is obvious that the iiame. will also be discharged directly against the lower, but at this time the front, face of the water-back.

When used in the iire-pot, it Will be understood the nipple end of the heater may be projected down through; the grate and out through the ash-pit door for the convenient attaching of the gas-supply pipe.

From the foregoing descriptiomftaken in connection with the drawings, it is thought the advantages of my invention will be readily.

IOO

can be quickly and conveniently placed in position either in the ash-pit or in the {ire-pot, the end inernber 3 forming a suitable support for holding the heater in the proper vertical position when the same is placed Within the ash-pit.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

As a new article of manufacture; a portable heater for water-back stoves; comprising a main feed-pipe formed of a series of pipe-sections joined by T-couplings, one end section having an adjustable T-shaped closure member, said T-shaped couplings having the rightangle melnber detachably connected and terminating at the outer end in a conical pindischarge; burners detachably secured over the conical ends of the T-laterals, said burn- 2o ers being in the nature of tubes having their outer or discharge ends flattened and having oppositely-disposed air-tight openings adjacent the coupling-laterals, and an adjustable nipple secured to the front section of the feedpipe, all being arranged substantially as shown and described, whereby by turning the T-closure at right angles to the projection of the tube-laterals the device can be supported in the ash-pit with its burner-tubes projected toward or between the grate-bars, and when turned in line with such tubes admit of the device being laid flatwise on the top of the grate bar with its nipple projected down through the grate-bottom, as and for the purposes specified.

JOHN P. IIOPPERT.
