Specification of Letters Patent.

Application led May 12, 19081 Serial No. 432,367.

resented Feb. 23, 1909.

To all whom 'it may concern:

Be it known that I, Emil. BEYER, a citizen of the' United States, residing at Newark, .in the county'of Essex and State of New Jersey, have invented certain new and useful Improvements in Burners for Blow-Torches;

c lates, more particularly, to a novel construction of burner which is used with a receptacle in which the gas-producing medium, such as kerosene, or the like, is stored under pressure, the burner being /constructed in such a manner, that the gas-producin medium is forced through the parts of the urnermechanism in a circuitous manner, andy is delivered-in a fine spray prior to its entrance into the burner vor ignitionchamber, the

sprayed gas-producing medium being inti-` mixed with air before its entrance@ matel v into t e burner or ignition-chamber, so asto produce a perfect mixture and combustible gas which is expelled in a burningcondition and a hot flame from the end-portion of the burner or ignition-chamber.

My present invention 'has for its rincipal object to rovide a novel burner or blowtorches, w ich shall be of a simple construetion, and shall be efficient -in causin the gasproducing medium to be intimatey mixed with air and delivered in a iine spray, under pessure, into the burner or ignition-chamr; and, the invention has for its further object to provide a novel means for producing a eircuitous passage of the gas-producing medium from the receptacle 1n which it is stored, to the point of the delivery of the said medium, where it is mixed with air belfgre entering the burner or ignition-cham- This invention has for its further object to provide an adjustably arranged spraying or delivery valve, which is to be used in connection .with `the burner hereinafter more fully set forth; and, furthermore, to provide in addition to a burner for blow-torches, a novel drip-cu such as will be hereinafter more fully set orth.

Other objects of this invention not at this time more particularly enumerated will be clearly evident from the following detailed description of the said invention.

Vitli the various objects of my present invention in view, the same consists, primarily, in the novel burner for blow-torches hereinafter set forth; and, the invention consists furthermore, 'in the use, in connection with a burner of the general character hereinafter set forth, of means for regulating and controlling the supply of the air into the ignition c amber; and, furthermore, to provide means for retaining the generated heat, as much as possible, within the ignition chamber.

The invention consists, furthermore, in the novel arrangements and combination of devices and parts, as well as in the details of the construction of the same, all of which will be more fully described in the following specication, and then finally embodied in the clauses of the claim which are appended to and which form an essential part of this p specification.

The inventlon is clearly illustrated in the accompanying drawings, in which:-

Figure 1 is an elevation of`a ortion* of a receptacle and a force-pump suc as used in blow-torches, and a side-elevation of my novel form of burner used in connection therewith, a certain portion ofsthe burner being represented in .longitudinal section. Fig. 2 is a longitudinal vertical section o f the said burner. Fig. 3 is a transverse vertical section taken on line 3-.3 in said Fig. 1,

.looking in the direction of the arrow w; and

Fig. 4 isnJ similar section taken on line 4-4 'in said Fig. 1, looking in the direction of the arrow ,both of said views being made on enlarged scales. Fig. 5 is a .top v1ew of a drip-cup and horizontal sectional re resentation of the ipe-connection upon w ich said cup is arrariged. Fig. 6 is a longltudinal vertical section, onnn enlarged scale, of portions of the burner, showing a modlfiedk construction of the same.

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

ReferrinY now to the said drawings, the reference-character 1 indicates a suitable receptacle, such as is used 'in the construcmember or element 12, and fromthel packtion of blow-torchesior the reception ofy a gas-producing medium, as kerosene or the like, said receptacle beiifigl provided in its upper portion with a tubular and interiorly screw-threaded enlargement or boss 2 which forms an outlet with which the supply tube of the burner is to be connected, substantially inthe manner to be presently more fully described. Reference character 3 indicates a tubular member whichA is suitably connected with the said receptacle 1, and isl made in the form ofa force-pump, which, while itserves as a handle for the receptacle 1,' also serves to produce a lpressure of air upon the gas-producing medium within the'receptacle 1, so as to forcibly 'emit the gas-producing medium from the sprayer valve of the burner, when the said vali/eis removed from its valve-seat, substantially in the manner and for purposes to'be presently more fully described.

The burner which embodies the principal features of my invention is indicated by referencecharacter Il, and thev same comprises a suitably tapered or cone-shaped flame or ignition chamber 5 having its enlarged endortion niade with a closing wall 6 which is ormed with a tubular andv ref-l erably annularly shaped boss 7 providingan inlet 8. The 'wall 6 is also formed with air-inlets 9, and in the side-walls of the tapered liame or ignition chamber, another air-inlet 10 may be provided.A Thevreference-,character 11 indicates the open endportion of the said llame or .ignition-chamber from which the flame `is forced when the deviceA is operated.

' tubular element ormember 16 being vSuitably connected with the tapered or cone-shaped casting in the form of. which the ignition chamber is usually made is a tubular conveying duct or element 12, the samev being preferably cast in one integral piece with the said tapered shellor bodyportion 5 formingthe ignition chamber. Upon one of its free ends the said tube-like element 12 is provided with a screw-threaded portion 13 for the screwing thereon of apacking-nut 14 in which is arranged a suitable packing 15. rlhe said tubular orductlike element 12 is also provided with a downwardly extending tubular element or member 16 which is ormed with a screwthreaded ortion 17 for suitably screwing 'the same into the interiorly screw-threaded enlargement or boss 2 into the receptacle .1, as wlll be clearly evident, and the said provided with a conveying duct or tube, as 18, which extends down into the interior of the receptacle 1, as will be clearly understood. Suitably 'arrangedwitliin the said tube-like element 12 is another tube or pipe-like member or`element, as 19, which extends from the screw-threaded Aend-portion 13 of the ying-nut 14, substantially as shown, the said tube or pipe 19 being bent at a right angle,

or approximately so, 'so as to provide an upwardly extending portion 20. Gonnected with said portion 20 is a horizontally eX- tending tubular member 2lwhich is chambered, as at 22, and is provided at'one end with an internally screw-threaded part 23, and at its other end-portion is made with a preferably cone-shaped valve-seat 24, sub@ stantially as illustrated in Fig. 2 ofthe drawings. y

The reference-character 25 indicates" athe valve-seat 24, to regulate` the spray 'of the gas-.producing medium, which 1s to be ejected from said opening, as may be found necessary to produce -the proper mixture of the medium and air at this point, and thereby provide the proper and most ei'iciently actlng ame within the ignition chamber formed by the shell or body-portion 5, as will be clearly evident.- The said rod or stein 25 may be provided .atl its end-portion which extends from the internally screw-threaded portion 23 with ahandle or finger piece, as 28, or othersuit'ably formed ngerpiece', for operating thesame. The member or ele- Cment 2l `may also be provided with a externally screw-threaded part.29 for the reception of a suitable packing-nut 30, and

packing 31 ,in said nut, in which the said substantia The previously mentionedv tube-like ele vment or duct 16 is provided with an outlet or o'ening, as 32, which registers with an y as shown.

annu ar groove r depression 33 in the ylin` drical surface of the tube-like element or member 19, and in the upper portion of vthe outer cylindrical surface of said 'tube-like v element or duct 19 is a longitudinally eX-.

tending groove or channel 34, 'which connects with the oove 33. Suitably arranged within the sai tube-like element or duct 19l is a cyllndrically shaped rod, as 35, in the upper surface of which is a'longitudinally extending groove o r channel 36, which communicates, at 37, with the groove or channel 34. The saidl rod 35 is also provided with` I two other grooves. or channels 3 8 and 39, the

groove or channel 38 being connected at its one end vWith theH groove or channel 36, by means of a short groove 40, and at its other while being ultimately mixed at this point, with the air. so as to produce a combustiblel end the said roove or 'channel 38 is connected with t e groove or channel 39 by means of another short groove 41, and the said, groove orchannel 39 terminating at the end of the rod 35 and being in commimication with the interior of the tubelike member or element 19, at or near the right-angled portion 2() of said tube-like member or element 19, as clearly indicated in said Fig. 2 of the drawings.

From the foregoing description of the several parts hereinabove described, it will be clearly evident, that the gas-producing medium, such as kerosene, or the like, which is contained under pressure within the receptacle 1, when the outlet in the valve-seat 24 has been opened, will be forced through the pipe or duct 18 into the member 16, and will then make its way through the circuitous passage-ways formed in the tube- like elements 12 and 19 and the rod 35, where it is converted into a vapor, being delivered into the chamber 22, and finally forced in a fine spray, which is regulated by the position of the rod, stem or spindle 25, from the outlet connected with the cone-shaped valve-seat 24 of the member or part 21. This line spray of the gas-producing mdium, as will be evident, is forced across the open space between the vend of the member 21 and the tubular boss -or inlet 7 of the shell or body 5, and

mixture, is forced directly into the interior or chambered portion of the said shell or body 5. The mixture can be readily ignited within said shell or body 5, by means of a lighted match, the lighted gas or flame being forcedfor use directly from the outlet 11 of said shell or body 5.' Any necessary addiv tional supply of air may bel added to the gaseous-mixture through theA holes 9 and 10 in said shell or body 5, as will-be clearly evident; If desired, a disk or plate 42 for regulating or for entirely shutting off the su ply of the air through the airholes or per orations 9 may be rotatably disposed upon the tubular boss or enlargement 7, as shown in the several figures of the drawings, said disk or plate 42 being formed with suitably disposed holes or perforations 43 'which registex-.with the holes or perforations 9, and said disk' or plate being provided with a suitably formed linger-piece, as 44, for moving the disk or plate backl and forth, as may be necessary, for entirely closing off the holes or perforations 9, or for reducing their supgly-area, as will be understood. The said isk or plate 42 is suitably held in its operative position a ainst the outer face of the iend-wall 6 0f tie shell or body 5, by means of the head of a suitable screw 45, the shank of which extends through an elongated opening 46 in said disk or plate 42, so as to allow for the necessary movement of the latter,

and is screwed directly into the wall 6 of the shell or body 5. L

1f desired,'the various parts of the burner may also be surrounded by means of a suitably formed guard or protector, as 47, which is preferably' of the 'general conformation shown in the drawings, and is provided in its closed end-portion 48 with a tubular hub 49 for arranging said guard or protector upon the valve-rod, stem or spindle 25, and securing it thereon by means of a set-screw 50, or other fastening means. The open endportion 51 of the guard or protector 47 is preferably made so as to extend for a -distance over the closed end-portion of the shell or body 5 and surrounds the same, as shown; and, in order that the rotary action for the adjustment of the valve-stem, rod or spindle 25 will not be interfered with, the said guard'or protector 47 is suiliciently cut away, as at 52, to permit of the proper rotary motion of the spindle or' rod 25, and of the adjustment of its cone-shaped valve-end, as will be clearly evident. The said guard or protector 47 '1s also cut away, as at 53, to provide a suitable opening, to permit the operator to manipulate the lingerpiece 44 of .the regulating disk or plate 42.` The said guard or roctector 47 is also provided with suitably isposed holes or perforations 54 through which a supply of air is admitted into the interior ofthe guard or protector for rreducingl a proper mixture of the gaspro ueing medium and air. A

While the member or device 47 serves as Va proper guard or protector against the hand of the operator being brought in accidental contact with the hot parts of the device, the

guard or protector also has this beneficial advantage, that the heat which is enerated at the point of mixture is retaine directly about t 1e member 21, and the parts contiguous thereto, thereby resulting in a quicker and more efficacious' gaseous mixture, and at the same time keeping the outside ofthe assembled partsof the device in a cooled con-` dition.

l A suitably formed drip-receiving device or cup 55 comprisin a tubular hub 56 and two elongated cup- s lapcd members 57 and 57 may, if desired, be arranged upon the tubular element or member 16, by having said tubular hub arranged upon said element or member 16 and suitably fastened thereto by means of a set-screw 59. Vhile the device 55 serves as a drip-receiving means, it will be evident, also, that it may serve as a starter or primary pan for heating the parts located above said pan. It will be understood, however, that the said drip-rereceiving device, as well as the previously mentioned guard or protector, may be dispensed with, if desired.

In Fig. 6, I have shown the tube-like member or element 19 provided with a slightly ing a modified means of circuitous conveymodified form of oil-feeding device, and in lieu of the grooved or channeled rod shown in Figs. 2, 3 and 4, l insert in said tube-like member or element 19, a series of wire-netting or gauze layers 60, which are spirallyl formed into a roll, so as to be fitted within said member or element 19, and thus providance through which the oil or gas-producing medium is compelled to pass in substantially v the manner as herein-above described.

From the foregoing description ofmy present invention, it will be clearly seen, that l have produced a simply constructed burner for blow-torches, and the manner of forcing the gas-producing medium to and into the i ignition chamber of the device will be clearly' f f combinations of the devices and parts, as

- drawings, and need, therefore, not be 4further evidentfrom the foregoing description and j from an inspection of the accompanying dwelt upon at this time. Y

I am fully aware that some changes may bemade in the various arrangements and well as in the details of the construction of the said parts, as described in the foregoing specification, and as defined in the appended claims. Hence, l do not limit my invention to the exactv arrangements and combinations of the devices` and parts as set forth' in the foregoing specification, nor do l confine myself to the exact details of the construction of the said parts as illustrated in the accom- -a main bod panying drawings.
