modiiied form or" a shaft and blades for use within the atomizer.
As disclosed in the-accompanying drawings, A denotes a four-way union having suitably coupled to the opposed branches 1 the oppositely directed pipe lines P embodying the returned portions P coupled to the opposite branches 2 of a T-union B. Suitably coupled to the intermediate branch 2* of the union B is the pipe line L' leading froma source (not shown) of steam or air or a mixture of both under pressure. interposed in the line L is a controlling valve V.
Coupled to one of the branches 1 of the union B is a pipe line 0 leading from a source of oil supply and the opposed branch 1 has coupled thereto a pipe length or section S. Engaged with the'outer or opposite end portion oi the pipe length or section S is a tubular head or casting H, affording a mixing chamber M and with which the pipe S communicates. interposed in the pipe line 0 is a controlling valve V of a conventional type. 1
The first named branch 1 of the union A has applied therein a plug 25 and disposed axially through said plug and in communication with the pipe line O is a tubular member or pipe 26 which extends through the opposed branches 1 through the pipe length or section S and into the mixing chamber M. The tubular member or pipe 26 is of a major diameter materially less than the mean diameter of the branches 1 and the pipe length or section S.
Suitably secured to the end portion of the tubular member or pipe 26 within the mixing chamber M is a nozzle or head N provided in its side wall with the slots 3 whereby the oil is discharged from said head or nozzle N in directions substantially radial to the longitudinal axis of the tubular member M or pipe 26.
The head or casting H, at a point substantially diametrically opposed to the connection between the said head or casting H and i the pipe length of section S, is provided with an opening 4: in which is snugly engaged an end portion of the housing 5 of the atomizer C.
The housing 5 as herein disclosed comprises an elongated tubular member having the end inserted within the opening i in tersected by a radially directed cross arm 6, preferably integrally formed with the housing 5 and provided at substantially its longitudinal center with an opening 6.
The opposite end portion of the housing 5 is provided with the substantially diametrically opposed and longitudinally directed open end grooves or channels 7. The base portion of each of said grooves or channels 7 adjacent to its closed end is provided with a pocket or recess 8. The periphery of said housing 5 at such end portion is also provided with the threads 9 to afford means whereby the large end of the reducing union 10 may be effectively engaged with the housing 5.
The outer or smaller end portion of the 1 union 10 is interiorly threaded as at 11 and with which threads are engaged the inserted end portion of a gas pipe12 of desired length and which pipe 12 has suitably engaged with its outer end the tip l i of any ordinary or preferred type.
15 denotes a sleeve from which diverge the arms 16, the free end portions of said arms terminating in the substantially parallel portions l6 adapted to snugly fit within the grooves or channels 7 produced in the housing 5. The portion 16 of the arms terminate in the inwardly directed lugs 17 which extend within the recesses or pockets 8 hereinbefore referred to. The outer faces ofthe portions 16 are provided with the threads 18 which, when the arms 16 are in applied position, are in continuation of the threads 9 so that when the reducing coupling 10 is in applied position, the arms 16 are effectively secured to the housing 5 and the sleeve 15 maintained at substantially the axial center of the housing 5 and at a point slightly in advance thereof.
In threadedengagementwithin the sleeve 15 through the outer end thereof is a shank 19 which serves as an adjustable bearing for the shaft 20.
A shaft 20 extends longitudinally through the housing 5 and has one end portion extending within the opening 6 in the cross arm 6 whereby said arm 6 serves as a hearing for the shaft 20. The opposite end portion of the shaft 20 extends into the sleeve 15 through the inner end thereof and is engaged by the inserted end of the shank or hearing 19. The shaft 20 is also provided with an outstanding annular shoulder 21 which bears against the inner face of the cross arm 6 whereby said shaft 20, through the instrumentality of the shank or bearing 19, is effectively maintained in working or applied position.
The shaft 20 inwardly of but in close proximity to the shoulder 21 is provided with thepropeller blades 22 so that the pressure of the mixture entering within the housin 5 will cause the shaft 20 to rotate at a relatively high speed. The shaft 20 within the housing 5 is provided with the longitudinally spaced blades 23 arranged in pairs with the blades of each pair substantially diametrically opposed. Adjacent blades 23 are also substantially perpendicularly related. As is particularly illustrated in Fig. 1, the blades 23 are substantially flat with their faces disposed longitudinally of the shaft 20 and each of the blades 23 is provided with a plurality of longitudinally spaced openings 24. As the shaft 20 rotates within the housing 5, the blades 23 operate to effectively convert or transform the mixture into a gas before said mixture enters the pipe 12. This particular type of blades 23 is especially adapted for use when the pressure is from twenty to seventy-five pounds. With a pressure between two and seventy-five pounds, it is preferred that the blades 23 be imperforate and of substantially spiral formation. With a pressure between seventy-five and two hundred pounds, the spiral blades 23 are preferably used and which blades are also substantially spiral in form but the coacting shaft 20 not provided with the propeller blades.
With a burner constructed in accordance with an embodiment of our invention, it has been fully established in practice that the flame burns without smoke and even burner constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason we do not.wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed.
