To all LU/wm, it may conce/11n:

Beit known that I, HERMAN A. PAQUETTE, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in ConvertibleSoldering-Irons, of which the following is a specification.

This invention relates to improvements in that type of tools which are designed or intended for use by jewelers, tinners, metal workers and others, mainly, for the purposes of soldering, fusing and brazing, and it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a tool of the above, named General character, which shall be vsimple an inexpensive in construction, strong, durable and eiiicient in operation, is with its part so made and arranged, that it can be used as a soldering-iron, or, if desired, can be instantly converted into a blow-torch, and used as such, or vice versa.

Another object is to furnish such a tool, which can be conveniently handled or manipulated and readily connected to an ordinary gas-fixture, so as to utilize the gas and pressure therefrom, thus dispensing with the necessity of em loying other means of compression to pro uce the necessary jet or current.

A further object is to provide means for regulating and mixing the gas with air as it is forced through the parts of the tool.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In the accompanying drawing, which serves to illustrate an embodiment of the invention: Figurel is a perspective view of the tool, showing its parts arranged for use as a soldering-iron; Fig. 2 is a longitudinal sectional view; Fig. 3 is a cross` sectional View taken on line 3-3 of Fig. 2 looking in the direction indicated by the arrows, and Fig. 4 is a greatly enlarged view inside elevation and partly in section of a tube adapted to be used in connection with the devicewhen it is employed as a blow-torch.

Corresponding numerals of reference refer to like parts throughout the dilferent views of the drawing.

The handle -of the device includes a metal tube 5, which 1s surrounded by a hand-piece 6, of any desired form and material, but

preferably of wood or some non-heat conductlng material, and of substantially the shape shown in the drawings. Each end of the tube 5 is externally screw threaded, for engagement at its front end with a metallic head 7, and at its rear end with a nipple 8, which is by reference providedl with a series of annu ar grooves 9, to receive and engage a flexible tube, such as rubber, used for connecting the nipple 8 and handle in communication with an ordinary gas fixture or other supply of gas under pressure. The nipple 8 1s provided with a valve 10, of the ordlnary or any well known construction, employed for regulating the flow of gas through the nipple 8 and tube 5 of the han'dle.

As'clearly shown in Figs. 1 and 2 of the drawings, the head 7 which is mounted on the front end of the tube 5, is provided with' a transverse opening 11, which has communicating therewith, through its rear port1on, a bore 12, or channel, which is stepped or enlarged from its rear to its front end,

and said bore communicates with the opening of the tube 5, as is clearly shown in Fig. 2 of the drawing. Pivotally mounted on the rear wall or surface of the opening 11, is a regulating plate 13, which is provided with a series of graduated openings 14, adapted to register one at a time with the front or reduced end of the bore 12, in the head 7, so as to regulate the quantity of gas discharged through the said bore or o ening. The regulating plate 13, is preferab y provided with indicating points 15, arranged to register with a mark or indicator 16, on the rear wall or surface of the opening 11, in the head of the device. Directly opposite the discharging end of the opening or bore 12, the head 7, is provided with an openin 17, which is extended longitudinally wit reference to said head, and is for the reception of the rear end or head 18, of a tube 19, which preferably has its front end and bore reduced as at 20, and is provided at the rear end of its bore with a' flaring opening 21, to receive the gas discharged from the opening or'bore 12 through one of the openings 14 in the regulating plate 13, and air throu h the opening 11 of the head. The head gis provided at a suitable point to enl ter the opening 17, with a set or thumb screw 22, used forsecuring the rear end or head 18 of the tube 19 in osition in the head. The tube 19 is provi ed in front of the head 1S thereon, or in front of the head 7 of the handle, with one or more openings 23, for the passage of air, so as to render the mixture of gas and air more eicient.

When the parts are arranged as above de? scribed, it is obvious that the device can be used as a blow-pipe, and that an extremely small jet or current will be forced from the front end of the tube 19, by reason of the pressure of the supply of gas, and that this jet or flame can be directed to the proper point on a piece or pieces of metal when the same are being fused or brazed. It is also obvious that if desired the tube 19 can be removed from the opening 17 in the head 7, and a larger tube 24, such as shown in Fig. 4 of the drawing can be inserted at one of its ends in the opening 17, of the head 7, of the handle, and fastened therein by means of the set or thumb screw 22, which larger tube can be used for directing a larger current or flame jet against the pieces to be fused or brazed, or, if desired, the device equipped with the larger tube may be used for burning off paint on woodwork and the like.

By reference to Fig. 4 of the drawing, it will be observed that the rear portion of the tube 24, is provided with a series of openings 25, for the admission of air, which openings will be located in front of the forward portion of the head 7, when said tube is in position therein. The quantity of gas discharged through the tube 5, of the handle can be regulated by moving the regulating plate 13 in the proper direction, so that one of the larger or smaller openings 14 therein may be brought into register with the discharging end of the opening or bore 12 in the handle head. 4

The soldering-iron consists of a bit 26, usually of copper, and has its front end tapered or wedge-shaped, and is provided in its rear portion with a cavity 27, from which one or more openings 28, lead forwardly in an inclined or oblique direction for the eXit of the burning gases. Secured to the rear portion of the bit 26, is a tube 29, which preferably has its rear end flared, as shown, and is provided near the rear end of the bit 26 with one or more openings 30 for the passage of air.

As is clearly shown in Figs. 1 and 2 of the drawing, the bit 26 is provided on its outer surface at points diametrically opposite each other with longitudinally grooved lugs 31, each of which has secured therein the front end of a supporting arm 32, which arms are secured at their rear ends in correspondingly formed lugs 33, on a collar 34, which is slidably mounted on the tube 19,

and may be fixed in any desired position on said tube by means of a set or thumb screw 35, which is seated in the collar 34, so as to engage said tube.

By the foregoing arrangement, it is evident that the soldering-iron can be adjusted on the tube 19, or any other tube having a larger or smaller bore and adapted to be fitted in the openings 17,0f the head, so that the discharging end of said tube may be placed at the desired distance from the rear or receiving end of the tube 29, and thus regulate the heat at the bit 26 of the soldering-iron, or if further regulation is required, this can be obtained by a proper'manipulation of the regulating plate 13, on the head 7, of the handle.

From the foregoing and by reference to the drawing, it will be readily understood and clearly seen that by employing a tool embodying my improvements, the pressure of the supply of gas is all that is necessary to render the tool eliciently operative, and that I am enabled to dispense with the ordinary means employed in soldering-irons and blow-pipes for producing pressure such as pumps, bulbs and mouth blowers. It is also manifest that by reducing the bore 12, in the handle head 7, the velocity of the gas passing through said bore will be increased, and

- that as 1t enters the flaring opening 21, of the tube 19, air will mingle therewith at said flaring part and be carried into and through said tube, in which operation air will also enter the openings 23, ofthe tube 19, or, if a larger tube, such as 24 shown in Fig. 4 of the drawing, is employed, additional air will enter the openings 25 thereof and thus cause perfect commingling of the gas and air, to the end that it will be discharged from the front end of the tube in such condition as to offer almost perfect combustion. A further mixture of the gas and air will take place in the tube 29, and cavity 27 of the bit 26, as it is forced through the same.

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

1. In a device of the character described, the combination with a handle having a passageway therethrough7 of a head mounted on one end of said handle and provided with a transverse opening and a bore communieating with said passageway and opening, a regulating-plate pivotally mounted on the head and having graduated openings adapted to register with the discharging end of said bore, and a tube mounted on the head in communication with said opening.
