Application filed. January 21, 1920. -Seria1 No. 352,946.

To all whom it may concern: I

=Be it known that I, WALTE ANDREW INGLEHART, a subject of the King of Great Britain, residing on Dundas street in the" town of Oakville, in the county of Halton, in the Province of Ontario, Canada, have invented certain new and useful Improvements'in Oil-Burners and Driving Means Therefor, of which the following is'hthe specification. 3

My invention relates to improvements in oil burners and driving means therefor and the object of the invention 18 to provide a burner in which the driving meansis. ca pable of being carried on the'mam shaft of the atomizer without being affected detrimentally by the heat generated by the burner, to provide a simple means automatr cally operated by the speed, of the motor sinking below a predetermined minimum for cutting off the flow of the oil supply to the 5 burner, to provide means for automatically operating an automatic signal to indicate when such oil flow is cut off, and lastly to provide such a' construction which will eliminate the objectionable humming sound caused by the revolving of the atomizer and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.

extending upward through the orifice 4. The upper portion of the member 8 is provided with an internal flange 9 carr ing the The lower en of the bearing member 8 is provided with an'up per casing member ll provided with orifices 12 into which extend screws 13 which screws pass through'the lugs 5 hereinbefore 'referred to thereby connecting the bearing member Sand casing member 11 to the' hanger member3 so as to be carried thereby. The lower edge of the member 11 is is an internally threaded boss the orifice of whichis directed tangentially into the interior of the upper'casing portion 11.. 16

is a lower casing portion which is provided with a flange 17 opposing'the flange 14 and secured thereto by screws 80. 90 isa boss extending downwardly from the casing member 16 andprovided with an internally threaded orifice-which is preferably located at the oppositeside of the casing to the boss 15.; The central portion of the casing member 16 is curved up so as to form a hollow boss 18 provided with an annular internal flange'19su pporting the annular ball race 20. 21 is themain shaft of my burner adapted to carry an atomizer at its upper end the scribe. 22 is a bearing cone secured to the shaft 21 and fitting within the ball race 10, the cone 22 and, ball race 10 being provided with ball bearings 23. 24 is a bearing provided with interposed ball bearings 25.

.26 is a water wheel formed by the central sleeve 27 secured to the shaft 21 and from .which radiate blades 28 which blades may be of any approved type. 29 is a hood which is carried by the lower end of the sleeve 27 so as to shield the bearing formed by theball race 20, cone 24 and balls 25 from the splash of water which passes through the casing member 16. 30 is a speed governor which comprises a collar 31 seconstruction of which I will hereinafter de-- 'coneextending within the ball race 20 and I,

curedjto the shaft 21, and sleeve 32 slidable c upon the lower end of the shaft and spring arms 33 carrying the governor weights 34. 35 is a disk which is secured in the annular recess 36 formed in the lower enrLcf the sleeve 32 bymeans of a screw 37 which isscrewed into the internally threaded end of'the sleeve 32 and by the washer 38 wh1ch bears against the lowerface of the disk 37 thereby making the disk form an integral the movement of the arm 42. it is a wheel eccentrically mounted upon the shaft 41 such'sha'ft being provided with an annular groove in which is secured 'a frictional band 46. By operating the arm 42 the friction band may be carried in and out of contact with the disk so as to regulate the speed of the mechanism as desired. 47 is an oil supply valve which is carried at the lower end of the hanger member 39. :8 is an oil supply pipe leading to the valve from any suitable source of supply. 19 is a pipe leading from the valve, the pipe 49 extending upward to the outside of the hanger portion 39 to a point above the casing member 11 being bent inward at 50 through the opening 51 formed in the hanger 3 the pipe then extending upward in close proximity to the bearing member 8 and being again bent inward at 52 into proximity with the shaft 21 being provided at its upper end with an outwardly turned spout portion 53.

5% is my atomizer which comprises a disk 55 which is in the form of a shallow conically shaped saucer having a central orifice 56 provided 'with an upwardly extending annular flange 57 and a downwardly curved outer edge portion 58 having a knife edge 59 and downwardly curved portion 58 opposing the upper end of the hanger 3 to form an annular discharge mouth 60. 61 and 62 are spoke members extending upward from the atomizer disk 5d and set at right angles one to the other such spokes being semi-circular in form and provided at theirpoint of intersection with depending notched lugs 63 and 64:. 65 is a pin extending diametrically from the upper end or the shaft 21 and protruding -i'rom each side thereof through notched lugs 63 and 64. thereby supporting the atomizer member 54: upon the shaft 21 so as to revolve therewith. 66 is a semi-spherical hood member which isfreely supported upon the semi-spherical spokes 61 and 62. The upper end of the shaft 21 is provided with a reduced extension 67 so as to form a shoulder 68 upon which may be placed washers 69 on which the intersecting portions of the spoked members 61' and 62 hear so as to regulate the height of the atomizer member 5a and consequently the size of the annular discharge orifice 60. The lower face of the atomizer disk 54 is provided with vanes Y0 which are arranged radially and depend into the upper end of the hanger member 3. 71 1s a water supply pipe which is provided with a nozzle 72;

The water is fed into the casing formed by the casing members 11 and 16 in a tangential direction having impact upon the blades wl 'ch radiate from the shaft 21 and are rigidly connected thereto. The shaft 21 is thereby rotated in the bearings formed within the upper ball race 23 and the lower ball race 25 revolving automatically the disk 5% onto the upper face of which oil is fed from the spout portion 53 of the pipe 49. The .oil fed onto the atomizer plate 54 is carried radially outward and formed into a film which is ejected from the edge 59 air being drawn upward and forced radially through the discharge orifice 60 so as to mix with the oil film as it is discharged. As the speed increases the speed is controlled by the disk contacting with the friction band d6.

lln er certain conditions the water pressure may sink so low as to allow the burner to go out. It is, therefore, necessary to provide means for automatically cutting ofi the oil supply when these conditions are brought about. In order to do this I provide the following mechanism.

91 is the valve stem of the valve 17. 92 is a lever which is pivoted at one end on the pin 73 carried by the hanger portion 39. 74:

s a pin connecting the valve stem 91 to the ever 92 intermediate-1y of its length. 7 5 is a which is carriedby the outer or free l of t 1e lever 92. 76 is a trip pin extendtrom the lever 92 intermediately between valve stem 91 and wei ht 75. 77 is at3 "ripping lever swung uponthe pin '78 car- --ied in the hanger member 39. The tripping ev r '77 is provided with an inwardlyexe ding arm 79 in which is screwed an adusting screw 80, which is located centrally o'ithe burner and directly beneath the center of the screw 37. The tripping lever 77 is provided with a depending'arm 81 proided with a notch 82 engaging the trip pin 7 6.

83 is an alarm bell provided with circuit wires 84 and 85 leading from-the bell terminals S6 and 87. The wire 84: is grounded on the hanger portion 39 and 88 is a wire electrically connected to the spring contact finger 86 which is insulated from the hanger member 39 at 87. 89 is a battery to the terminals of which the wires 85 and 88 are connected.

When the water pressure decreases below the minimum the governor arms are drawn inward carrying the sleeve 32 downward and the head of the screw 37 into contact with the screw 80 so as to depress the arm 7 9 of the trip lever 77. By this means the notched portion 82 of the trip lever is car- I ried out of engagement with the trip pin 76 thereby freeing the lever 92 which is carried downwardby means of the eweight 75;

terminal of: the battery 89 and from the other terminal of the battery through the 1 wire 85 to the bell terminal87 through the bell magnet to the terminal 86 a and from thence by the wire 84 to thegrounding point on the hanger member 39 which is formed of conducting material allowing the circuit to be completed through thehanger mem- T ber, lever 92f to the springgcontact 86 thereby sounding the alarm,

From this description it will be seen that I have devised a burner in which a simple drive is providedwhich 1s carriedby the shaft for revolving the atomizer and such, I p.

, ernor so as to r se and fall with the operaas will not be affected by the heat generated by the binner. Also Iliave provided simple I means for cutting off the Oll supply andsounding an audible alarm simultaneously with thecutting off of such supply so that there will be absolutely no danger of the oil overflowing when the burner goes out. At the same time I have provided an atomizer which is located entirelyon the outside of the hanger support and being of a large diameter it may be-revolved ata low speed at thesame time producing a high peripheral speed and thereby, overcoming the humming sound which is produced by revolving atomizers as previously constructed.

The great detriment in centrifugal burners has been that the motor could not be di- 7 rectly connected to the driving shaft with out being seriously affected by the heat generated by the burner. By the employment of a water motor such as described I am en-' abled to simplify the drlving means by con- 1.
