I Application April 9, 1937, Serial No. 135,925 7 Claims. (Cl. 1267-44) My present invention relates .to yheat control rated my device or, an independently manufac apparatus for oil ranges, and Vmore ,particularly to tured oil burner'using my improved apparatus improvements incorporated in combination with may beinstalled in the older conventional coal or combination ranges. Ineach instance ,the instal certain apparatus disclosed in_my earlier applica lation may differ slightly incorporating some or ‘5 "5 tion entitled Heat control foroil burners, ñled all of the features shown in the drawing, as will SeptemberZG, `1936, Serial Number 102,665. The principal object of my improved apparatus be described further along in the present specifi cation. In the assembled view shown at Fig. 1, it is to be assumed that the apparatus is to be added to 10 conventional oil range burners in combination is the combination of a rotatable Vdamper operated " from the outside _of the range in which th'e oil 3" burner is used and which makes it possible to di-4 rect the heat .either over the oven~ or against the top of the rangeeither in a vertical direction or at with `combination oil and gas ranges in which II illustrates a conventional perforatedsleeve to an angle thereby concentrating heat Íat desired ,n points; Il" ' , ' ' ` gether with the base I2 and support I3. . Another Objectis an improved means of mount ing the apparatus and adjusting the same for >var ious positions; ` Still another object‘is quick demountable means for removing the apparatus with particular refer-4 ence to the damper portion, andother objects comprising the construction and operationof my invention will appear as' the description loi the device'progresses. iL C ` ` 'In the drawing illustrating the preferred em bodiment of .my invention, , ' ` Fig. 1 is a side elevationof the apparatus which is mounted in‘ combination with a conventional oil range burner in arange, the range proper kbe ing shown in .dot-and-dash lines; - Fig. 2 is a top plan view of apparatus particular ly showing the damper control portion; ' Fig. 3 is a bottom plan of the top showing the method of attachingthe supportingbracket to the head portion; ‘ Y» Fig. 4 is a cross-section taken on the line i4-II of Fig. 2; Fig. 5 is a perspective view of the supporting bracket which holds the apparatus in place; Fig. 6 is a perspective view of members which 'l are attached to the front of the range and 'to which the bracket attaches; Fig. 7 is a perspective view of vthe outside con trol member which operates `the rotatable damper in the top of the apparatus,-and 'I3 Fig. 8 is a side elevation, partially-broken-away, showing the two sleeves ~formed as one piece. My present improved apparatus is designed to meet several conditions as will beexplained. As shown in Fig. 1,w~the range I0, Ashown in dot-and #70 dash lines, vmay be a combination gas and oil -in stallation in which separate independently manu factured oil burners areinstalled and whichdo not come equipped „with my apparatus. In an other instance :the range I0 may-be manufactured 5‘5 together with `vanoil Lburnerhin »which is incorpo With such an installation, I mount my improved ap- l5 paratus I4 over the sleeve II as a separate unit and support it in an adjustable manner on the in side surface of the range Ivß, as shown in Fig. 1. The apparatus p_roper comprises a top member I5, N) O better shown in Figs. 1 to 4 inclusive, which is further vprbvided with an opening I6 and a `de-pending flange Il, the `front side of which is open, as shown at I8 in the bottom plan view illustrated at Fig. 3. On lthe top of the top member I5 I have located boss members I9 and 2B which form open 25 bearings in which is journalled a damper disc rnember‘ZI on trunnions 22 and 23. On the outer end‘of the trunnion 22 I have provided a square end 24 over which is fitted a hollow square tube 25. At Fig. 7 I have shown a regulator member 30 comprising _a shaft 26 squared at 2l and shoul dered at ¿2_8` and having an indicating handle member v29.- preferably positioned so that its majoraxislìes in the same plane as the diagonal corners of the squared end 21. In Fig..4, it will be 35 noted that'the squared end of ,the trunnion 22 is located so that its diagonal corners are at right angles _to the iiat sides of thedamper 2l such that the indicating handle member `29, when properly assembled, will properly indicate .the position of 4U the damper >from lthe koutside of the range, as shown in Fig. 1. Preferably the unit shown at Fig. r1 is cast _in onepiece but it _may _be assembled from several pieces if desired. When the member shown at Fig. 7 is assembled„it is passed through 45 the iront of the >range IILas shown at Figs. `1 and 2„ and a compression spring-26 is placed onthein side. A retaining washer 211 ~is then placedon the inner squared end 25 against the spring 261 and is held inlplace by means of a Cotter-pin _281 which Ui O passes through the pin hole 291 in the member 21. The squared member 25 4may be pinned at 30 >to the trunnion'memberM through the pinhole 3| or. it `may be -`fixed to the member 2'I,k as the case may be. \ 55 2 V 2,129,817 It will thus be apparent that when the unit shown at Fig. ’7 is pulled out from the outside of the range l0 it will be disengaged from the trun nion 22 and the damper member 2| may then be readily lifted up and off of the top I5. An eye member 32 is attached to the damper member 2| to facilitate its removal. Attached to the under side of the top member I5 is a semi-circular sleeve member 33, the side facing the oven 34 of the range I0 being open. The sleeve 33 is held in place in any suitable open end I8 of the top member I5 in much the same manner as disclosed in my previously re ferred to application. If it is desired to divert heat from the oven to the top of the range the damper 2| may be turned from the outside of the range and tilted to any angle desired thereby al lowing the heat to be directly applied to the top of the range. The maximum position is natural ly when the damper is in a vertical direction. Inasrnuch as practically all range oil burners are installed in pairs it will be apparent manner, as by the pin 35 located in the bottom side that with my dampers 2| set at opposite angles of the top I5. This pin is- located slightly to the ' I am able to concentrate or direct the heat rear so that the sleeve 33 when in place is tightly ~ 'in a converging manner to the center of the top bound against the recess 36 in'the back of the 0fV the range thereby greatly intensifying the top member I 5. Any other suitable means of Y temperature at this point. At the same time, I 15 attaching the sleeve 33 to the top member I5, as may divert only a portion of the heat generated screws or rivets, Will suffice equally as well. sending some of it to the oven and some to the The means for supporting the unit I4 in place top of therange, as desired. With such an ar 20 is illustrated in Figs. 5 and 6. In Fig. 6 I have rangement the necessity of removing vthe covers shown bracket members 31 having open foot por tions through which bolts may pass to fasten the said brackets to the front of the range I0, as shown at Fig. l. These brackets are reversible. On the top of these brackets I have positioned a horizontal slotted bar member 38 which may be bolted to the free legs of the brackets 31. With such an arrangement it will readily be seen that I may vary the elevation of the bar 38 together 30 with the brackets 31 and vat the same time I may vary the position of‘ the bar 38 outwardly or in wardly with respect >to the front of the range l0. At Fig. 5 I have shown a perspective view of an other bracket 39; the rear end of which is pro vided with a right-angled wedge member 45|Y which is adapted to ñt in the slot 42 in the bar 38. On the front end of the member 39 I have provided a vertical side member 43, the lower portion of which is slightly curved. The top p0r tion of the member 43 is adapted to be inserted in the recessed portion 36 of the top member I5 between the sleeve 33 and the back of the flange I'I, better shown at Figs. 3 and 4. The bottom portion of the member 43 bears against the lower portion of the sleeve 33 and supports it together with the top I5, as shown in Fig. 1. In Vthe po sition shown in Fig. 1, the sleeve 33 is positioned closely around the conventional perforated sleeve |I, the top edge of which is slightly higher than the bottom edge of they sleeve 33. ' It will thus be seen that in an installation of the type shown in Fig. 1, my improvedappara tus may be positioned `and adjusted in any de sired relation to the range burner within reason able limits. In other words, it may be easily and quickly adjusted to its proper location with a minimum of effort andrtrouble. shown in my prior application is avoided and much greater flexibility of heat control is had making it possible to obtain concentrated heat on top of the range and at the same time getting suiiicient heat delivered to the oven for baking. 25 Another important feature of the top member I5 which should not be overlooked is the fact that the opening I6 in the top is smaller than the outer sleeve II and the result obtained is that the heat Vis slightly retarded due to the fact that 30 it is slightly converged toward the center of the burner and thereby slowed Yup to the effect that the base I2 becomes hotter and the gases are more completely burned greatly increasing the eiiiciency of the burner, the net-result of which is more heat with less oil consumption than is 35 possible where the sleeve I I Vis not in combination with the unit I4. -'I‘he heat trapped temporarily under the flanged top member I5 reiiects against the base or bowl of the burner causing more per Vfect combustion of the gases generated thereon. .When the', above apparatus is used in certain types ’of older coal ranges where the under side of the top of the range is lower it may be desir able to remove the dampers from the` top I5 when all the heat is desired to be directed or diverted under the top of the range owing to the fact that insufficient clearance is present to allow the 40 damper to be'turned to a full open position, For such installations I have provided the eye mem ber 32 so that a hook may be inserted therein and the damper 2| removed entirely. When such removal is made it is only necessary to pull out the member illustrated at Fig. '7 and lift the damper 2| off of the top I5 replacing it when it is desired to use the oven. Even under such in ' stallations the damper may be rotated part way In installations in which the oil burner is built open and when two units are opposed or con-> into the range and properly adjusted at the fac verged toward each other suflicient heat will be tory, the sleeve 33 and the conventional sleeve present on the top of the range for the greater 60 |I may be made in onevpiece, as in Fig. 8. In' portion of the time. l . > such construction the upper portion 33a is open in the same manner as shown in Figs. 1 and 3 in the drawing, the open side being above the upper perforated portion of the sleeve IIa adjacent the oveny side of the range. With such construction the brackets and bar member shown inV Figs. 5 and 6 will be eliminated but the damper and apparatus shown in Figs. 2'and` 'l will be used. ’ In operation, the damper 2| performs a very essential and important function. When the damper is positioned as shown at Figs. 1 "and 2 in the drawingrthe maximum heat is Vdirected out 75 over the top of the oven 34 passing under'rthe Itvwill thus `be seen that while I have shown my improved apparatus somewhat in detail yet it is to be understood that I may vary the con struction in proportion within wide limits with out departing from the spiritr of the invention.
