SOLDEBING-IRON HEATER.

Application filed June 9,

To all whom it may concern.

Be it known that I, JosnrH NEEDHAM, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Soldering Iron Heaters, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to soldering iron heaters and particularly to apparatus of this class designed to be used in workshops or other manufacturing institutions, and the object of the invention is to provide a heater of the class and for the purpose specified in which high pressure fuel gas is preferably employed as the heating medium; a further object thereof being to so construct the heating apparatus as to maintain an even degree of heat and to equally distribute the flame discharged into the heater; and with these and other objects in view the invention consists in an apparatus of the class and for the purpose specified which is simple in construction and operation and efficient in use.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a front view of my improved heater;

Fig. 2 a partial section on the line 2-2 of Fig. 1; r

Fig. 3 a partial section on the line 33 of Fig. 2; and,

Fig. 4 a partial section on the line 4 ff of F ig. 1 and indicating the method of supporting soldering irons in connection with the heater.

In the practice of my invention I provide a base frame 5, which is approximately rectangular in form and is provided in its corner portions with angle iron legs 6. The inner face of the frame 5 is provided below the top portion thereof with inwardly directed flanges 7 which form table or support for a heater or furnace body 8 com posed of separate top and bottom parts 9 and 10 joined, as shown at 11.

My improved heater is of the general form and construction of a furnace con structed on a comparatively small scale and Specification of Letters Patent.

Patented Nov.,15, 1921.. 1920. semen No. 387,604.

the separate parts 9 and 10 are preferably composed of fire-brick or similar material. The separate parts of the body 8 are molded separately to form when said parts are placed together, in the manner shown in the accompanying drawing, a central heating or furnace chamber 12 which opens outwardly through the front wall of the body 8 as shown at 13, and this chamber or the top and bottom walls thereof are provided with inwardly directed and longitudinally arranged beaded portions 14 and 15, which divide the chamber 12 into two longitudinally arranged and approximately cylindrical compartihents 16 and 17 placed in communication as shown at 18.

The bottom part 10 of the body 8 is provided centrally of the chamber 12 with a passage 19 which opens into the chamber 12, as clearly shown in Figs. 2, 3 and 4, and mounted in the passage 19 is a gas burner with which is connected a supply pipe 21 which passes throughone of the walls of the frame 5 and to which is secured a suitable injector 22, part of which is illustrated in Fig.1.

Formed in the part 10 of the body 8 are oppositely directed passages 23 and 24, which communicate with the separate compartments 16 and 17, and also with passages 25 and 26 formed in the periphery of the parts 9 and 10 of the body 8, as clearly shown in Figs. 3 and 4. The passages 25 and 26 meet centrally of the top portion of the part 9 of the body 8 and communicate with a backwardly directed passage 27 formed in said part 9.

The body 8, or the separateparts 9 and 10 thereof, is inclosed in a suitable casing 28 provided on its inner face with a non-heat conducting facing 29, preferably composed of asbestos. The casing 28 is held in position by front and back approximately arcshaped bands 30 and 31 into which the front and back edge portions of the casing 28 fit, as clearly shown in Figs. 2 and 4C. The bands 30 and 31 pass into the top portion of the frame 5 and are secured thereto by screws 32 which securely hold the casing 28 in position. The bands 30 and 31 are each composed of L-shaped or approximately L- shaped strips, and one of the flanges at the top of the strips 31 is enlarged as shown at 33 in Fig. 2 sufficiently to cover the rear end portion of the passage 27. The band 31 is also provided centrally of the top portion keep said furnace thereof with an upwardly directed tubular extension 84 which is approximately elliptical in form and a flue pipe may, if desired, be connected with said tubular extension to carry the gases of combustion to a suitable point at which they may be discharged. The casing 28 and facing 29 thereof are also apertured as shown at 85 in line with the tubular extension 34 in order to place the passage 27 in communicationtherewith.

The front of the frame 5 is provided with an approximately L-shaped extension 36, and the upwardly directed portion 37, or the top face thereof, is notched out as shown at 38. In the use of the apparatus and when suit, able soldering irons 89, two of which are indicated in dotted lines in Fig. 1, are placed in the heater, or the chamber 12 thereof, the shanks 10 of said soldering irons will rest in the notched portion 38 of the extension 36.

The part 10 of the body 8 is recessed at the opposite sides of the central bead 15 thereof, and at the opposite sides of the central transverse plane of the chamber 12, as shown at 4:1 and 4:2. The recesses 41 are in the compartment 16, while the recesses a2 are in the compartment 17, and these recesses form in the compartments 16 and 17 central ribs 13 and a l respectively. The ribs 4:3 and 14 form the supports for the head end portions 45 of the soldering irons indicated in dotted lines in Fig. 1, and the recesses 1-1 and 42 at the opposite sides of said ribs permit of the passage of the flame or products of combustion around the head portions 45 to thoroughly and evenly heat said head portions.

In the use of the device the gaseous mixture is introduced into the injector 22 through the pipe 21 to the burner 20 and is ignite-cl within the chamber 12 and the flame from the burner 20 strikes the central. beaded portion 14 of the chamber 12 and directs the flame laterally as indicated by the arrows in Fig. 3, and the products of combustion are discharged laterally through the passages 23 and 24 in the part 10 of the body 8 upwardly through the passages 25 and 26 into the passage 27 at the top of the part 9 and out through the tubular extension 3%. It will also be apaarent that the flame within the separate compartments 16 and 17 will pass through the recessed portions L1 and l2 around the head portions d5 of the soldering iron to heat the same.

By passing the products of combustion over the part 9 of the furnace body 8, 1 prevent the chilling of said furnace body and body at an even temperature at all times. The passages 25, 26 and 27 as well as the passages 23 and 24: function as a jacket for the central portion of the furnace body 8 for the chamber 12 of said body.

It will be apparent that soldering irons may be placed in and remo *ed from the separate compartments 16 and 17 whenever desired, and with my improved construction the head portions 45 of the soldering irons will be equally and properly heated by reason of the method of distributing the flame and the products of combustion around said head portions. it will also be apparent that while I have described my improved heater or furnace, as particularly designed for the purpose of heating soldering irons, I am not necessarily limited in this respect as the apparatus may be used for heating various other articles, if desired, and changes in and modifications of the details of construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
