WILLIAM n. RAY, or'sm rninwcisco, can'rronm To all 'whom'z't may concern: Be it known that I, WV citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burners, of WhlCh the following is a specification.

,This invention relates to oil burners and pertains especially to rotary burners o t type shown and described in my pending application Serial Number 874,754, filed November 30, 191.4, entitled Oil burners.

One of the objects of the present invention is to provide a hollow motor shaft having a stationary fuel oil feeding pipe passing therethrough to permit delivery of the oil to the rotary atomizer through the shaft, thus permitting partial coolin of the motor, and similar] a pro-heating oi the oil .before delivery to t e atomizer. Another object of the invention is to provide means for center ing and adjusting the osition of the oil deliverin ipe with re ation to the interior wall 0 t e hollow motor shaft. A further object is toinclose the motor proper with an open-ended casing and to connect one end of said. casing with the suction side of the fan; in this manner causing a constant in-rush of air around the motor which cools the same andsimilarly raises the temperature of the Further objects will hereinafter appear. The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and s'cflaimed, in which-- {Figure 1 is aside elevation of the ,oil burner partly in section.

Fig. 2 is a cross section of line 2-2, Fig. 1. Fig. 3 is a longitudinal section throu h the motor shaft, showing the position of t e stationary oil delivering'tube and the means whereby it is adjusted.

Referring to the. drawings in detail, A"indicates a motor; 2 the motor shaftwhich in this instance is hollow, and '3 a centrifugal atomizer secured on the outer end of the hollow shaft. Oil is delivered to the atomizer through a stationary pipe 3 passing through the shaft and air to assist combustion and also atomization of theoil discharged by the atomizeris delivered from a high pressure fan enerallyindicated at 13 also secured upon t e shaft 2 and-driven in unison with same. Surrounding the outer bearing 4 of the motor and secured to the H 1AM R. RAY, a I

bracket 5 which supports said bearing is a cap-like member 6. This member is pro- "vided with a-plurality of arms 7 and an extension 8 Which is adapted to receive a valve 9 of any suitable construction. The stationary pipe 3 is screwed into the extension 8 as indicated at 10, and oil delivered by the valve 9 passes downthrough a passage 11,

7 and is larger in diameter than the pipe 3 I which passes therethrough. Passing through the sleeve 13 is a plurality of adjusting screws 14 preferably four in number. V These screws are adapted to engage the ipe 3 and spring it in one direction or anot 'er, in-this manner prevent-ing rubbin of the pipe, against the interior wall 0 the shaft and making it possible to adjust the position of the pipe 3 to assume an exact central position. The extension 8 is preferably provided with a screw plug 16 at its outer end which may be removed as occasion demands, to permit insertion of a. cleaning rod or like means not here shown. A rod inserted at this point may be forced directly through the pipe 35 and willin this manner remove any carbonized oil or other substance which might have a tendency to choke the feed pipe. The

' said pipe supported and connected as here shown is simple and substantial in'construction, is leak-proof and may be appliedto practically any form-of centrifugal atom-y izingburner of a type'here shown. In the o eration of electric motors of the type 's own, it is well known that the hi h s eed of the armature produces considers 1e heating action." This heat is employed to advantage in the present instance as it is trans-.

mitted through the shaft 2 to the oil delivering pipe- 3, in this manner raising the temerature of the oil to 'such an extent that it 1s more easily handled by the centrifugal atomizer and conversely an advantageous reduction of motor temperature is obtained.

For the purpose of further decreasing the temperature of the motor an open-ended air around the motor is thus insured'which not only reduces its-temperature, but it also causes a considerable increase in thev temperature of the air before it passes through the fan and reaches the fire zone.

-The materials and finish of the several parts may otherwise be such as the judgment and experience of the manufacturer may dictate.

I wish it understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims, and that I do not wish to limit myself to the specific design and 'constructionhere shown.

Thefurnacepljate' together with the hinge mounting of. the fan casing-and the oil connections formed through the ,hinges, although shown, does not form a part of the present application as it is more thoroughly illustrated .and claimed in my co-pending application, Serial No, 96,108, filed May 8-, 1916, entitled Oil burner.

Having ,thus deScribed-niy. invention, what I claim and desire to secure by Letters Patent is.:.-.

. 1. In an oil burner, the combination with .an electric motor having a hollow shaft,-of an atomizing, head secured on one. end of the shaft, a stationary pi-peextending through the hollow'shaft to-deliver oil to the atomizer and adapted to cool the. motor and heat the oil, and means for adjusting. the oil delivering pipe with relation to the interior wall of the hollow shaft.

2. The combination with a motor, a hollow motor shaft, and an atomizing cup secured on the shaft, of a stationary pipe ex tending through .the shaft and having one end extending into the atomizer, means fordelivering oil to the stationary pipe, and adjustable means engageable with the stationary pipe .to spring or bend it-with relation to the interior of the hollow shaft. p

3. The combination with a motor, a hollow shaft ,,and a'n-atomizing cup secured on the shaft,'-of a stationary pipe extending through the shaft and haying one end extending intothe atomizer, a stationary sup} port for the opposite end of the pipe, having a passage formed therein communicating with the pipe, means for. delivering oil to said passage andfa plurality of set-screws in the support engageable with the pipe to adjust its position withrelation to the interior of the hollow shaft.

4. In an oil burner, the combination with a hollow shaft, of means for revolving the shaft, a centrifugal atomizer on. one-end of the shaft, a stationary pipe extending through the shaft and opening into the stationary pipe.

atoniizer, a stationary member supporting the opposite end of the pipe, said member having a passage formed therein communieating with the pipe, means for delivering oil to the passage, means forregulating the flow of oil through the passage, and means engageable with the stationary pipe adapted to bend or spring it with relation to the interior of the hollowmotor shaft.

5. In an oil burner, the combination with ahollow shaft, of means for revolving the shaft, a centrifugal atomizer on one end of the "shaft, a stationary pipe extending through the shaft and opening into the atomizer, a stationary member supporting the opposite end of. the pipe, said .member having a passage formed'therein communicatingwith the pipe, means for delivering oil to the passage, means for regulating the flow ofoil through the passage, and means carried by the support for centering the pipe with relation to the interior of thehollow shaft and the atomizer. V
