' TORCH msrninurnn-nnnn f f Application filed July 26,

the following is a full, clear, and exact description thereof.

' My invention is directed to the provision of means of providing communication betweenangularly disposed groups of passageways in a distributer head or other member, and my invention finds particular applicationin connection with the distributer torch head of an ignition device of the type shown in my co-pending application for patent filed llilar. 18, 1919. Serial No. 283,325, and adapt: ed for association with a gas stove to light any one of the plurality of burners by directinga single torch flame toward the se lected burner, gas being supplied to the distributing head through a plurality of tubes.

' It is primarily the object of my invento provide a method of forming'series of communicating angular passageways a member of this character which, reduces to a minimum the number of drilling and other machining operations necessary in forming the member, whereby to'procure a decided economy in manufacture and whereby to permit the provision of an exceedingly simple and compact structure.

{It is more particularly the object of my invention to provide an'arrangement where by various of the passageways sections of the device may be cast in the device.

With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of the parts as hereinafter described and defined by the appended claims.

In the accompanying drawings:

Figure 1 is an elevational view of the disassembled sections of a torch distributor head embodying my invention.

Fig. 2 is a side elevational view of the distributer head with its sections assembled.

drawings,

sleeve is formed with sleeve, is disposed slightly the 1919. Serial No. 313,461.

Fig. 4 is a longitudinal sectional view through the head. v I hFig. 5 is a diagrammatic laid out view of t e the head showing the relation of the grooves cast therein.

Referring nowmore particularly to the I form the distributer head in two cast sections, a sleeve 10 and a relatively longer core cylinder ll which may be provided witha longitudinal central passageway 12 to lighten the structure. A laterally extending boss 13 is formed on the lower portion of the sleeve, and the upper portion of the radially outstanding lugs 14- for supporting a shield for the torch head. A series of passageways 15, 15, 15 and 15 are drilled through theboss l3 and are open at the inner periphery of the sleeve, these passageways being arranged in quadrangular relation and being adapted at their outer ends for communication'with supply tubes for the distributer head.

The cylindrical section is cast with a diameter slightly greater than the internal diameter of the sleeve'lO, and a series of spirally extending grooves are cast in the peripheries of these sections, these grooves corresponding 1n numberto the number of drilled passageways which may be varied to 'meet differing conditions of use for which the device is intended. One of the peripheral grooves has one end 16 adapted for communication with the sleeve passageway 15 when the core cylinder is inserted in the sleeve and this groove extendsspirally up Patented g. s, race.

peripheral surface of the core section of ward and terminates in an inset portion 17 when the core is inserted in the below the upper A'second groove has one which,

end portion l6 adapted for communlcation 'wlth the sleeve passageway 15, said groove extending spirally downward and around groove end 16 and thenspirally upward'in a reverse direction, terminating in an inset portion 16 adjacent the portion 16". A third groove has one end portion 16 adapted for communication with the sleeve passageway 15 and extends spirally upward below the second named groove and terminates in an inset portion 17. The fourth groove has one end 16 adapted for Certain portions and 18 in a circumferential series about the upper peripheral portion of the core, and when the core is disposed within the sleeve these inset portions form the upper end of a series of inclosed passageways which are in communication with the laterally extending pas-c sageways 15, 15 etc., oi the sleeve boss of the grooves are widened to provide draw faces a facilitating the formation otthemold sections of the core. The core is provided with a series of boreslS, 18, 18 and 1S drilled from its top to the inset groove portions 17*,17? etc, thus providing vertically extending ports at the top ofthe distributer head in which may be set jet tips 19, as shown in Fig. i to direct torch flames selectively in any one of a plurality of direct-ions.

In carrying out my improved method of forming the distributor head the sleeve 11') and core cylinderll are cast in the shape described. The bores 15*, 15?, etc., 18". etc, are then drilled in said sections and the inner periphery of the sleeves and the peripheryot' the core are finished to suchrelativediameters that the core will fit in the sleeve when the sleeve ras been expanded by heating- The sleeve isthen heated, and the core inserted therein with its grooves in proper coincidence with the inner ends of the sleeve bore and the sleeve is permitted to cool whereby it shrinks on the core, thus connecting the sections in a practical integral block and closing the cast-in grooves of the core sothat a series of closed angular passageways are formed in the distributer head having their terminal portions disposed in right angular groups. By my improved method, the only machining operations necessary in the formation of the passageways consist in finishing the meeting peripheral-faces of the sections and in drilling the bores 15, 15mm, and 18, 18" etc. and" an exceedingly simple and compact structure is procured.

lVhile I have shown'and describeda preferred embodiment of: my invention it will be appreciated that various changes and modifications of structure and of operative grooves.

steps may be employed to meet differing conditions of use without departing in any manner from the spirit, of my invention.

What is claimed is: i

i 1. "A distributer member comprising a sleeve provided with a series of apertures open at the inner periphery and a core cylinder secured in the sleeve and provided with grooves extending sprrally in its perlpheral surface,

each ot'said grooves being closed by the sleeve and having one end portion in communication with a corresponding aperture of-the sleeve.

' 2. A distributer -1nember comprising a sleeve provided with a series of apertures open at the inner periphery of the sleeve and, a corecylinder secured in the sleeve and provided with grooves extending spirally its peripheralsurface, eaeh'oi said grooves being closed by the sleeve. and having one end portion in communication with a corresponding aperturefof the sleeve, said core cylinder being provided with longitudinally extending apertures in communicaof the sleeve tion with the other end portions of the V distributor member comprising a a group of I apertures 3. sleeve provlded with o 3611 at its inner 'eri her .a core 0 linder secured in the sleeve and provided with a peripheral groove communicating at one end with one of the sleeve apertures and eX- tending spirally therefrom said cylinder being also provided with a second groove communicating with a. secondsleeve aperture and extending spirally'toward the said endof the first named around said end of the groove and extended spirally in a reverse direction.

at. A distributer member comprising a sleeve provided with a series of apertures opening at the inner periphery of the sleeve, and a core cylinder secured in the sleeve and provided with grooves extending in its peripheral surface, each of said grooves being closed by the sleeve and having one end groove and then portion in communication with corresponding aperture of the sleeve.

In testimony that I claim the foregoing l have hereunto set my handjat Milwaukee, in the county of Milwaukee and State of Wisconsin.
