To all fwzfma vit may concern.' Be it known that ll, HENRY M. Surname resident of Quincy, Adams Countypllllnois, .a citizen 'of the Unlted States, have invented' a certain new and useful improvements 1n lleating Systems for lincubators, Brooders, and the like, of which the following 1s a speciication Y 'llhis invention relates to heating systems 1o for broeders, incubators, and the like.

rllhe objectof my invention is to maintain a constant, uniform, and unobstructed flow of oil to the burner. A further object of my invention l1S to construct a controlling device which is to be placed between the supply tank and the burner, which will maintaina constant oil level in the burner.

Another object of the invention is to so 2o construct the controlling device that it may be readily adjusted to effect the different oil levels, thereby reducing or increasing the.

flame as desired.

A further object is to arrange a cut-off 25 within the controlling device in order that 'the supply may be completely shut of when desired, and opened again, whereupon the oil will assume theoriginal level.

A further object is to arrange the adjust- 3o ing and cut-ofi' devices externally of the controlling device. Y

` A further object is to arrange the upright portion of the supply-pipe adjacent to the burner far enough away from the burner to prevent the oil from becoming vaporized.

ln the accompanying drawings Fig. 1 is an elevation, partly in section disclosing my improved heating system;

Fig. 2- is an enlargedview of the burner 410 partly in section disclosing a structure of the feed-pipe adjacent thereto;

Fig. 3 is an enlarged transverse section on line 3--3 of Fig. 1, disclosing the controlling mechanism; H Fig. 4 is an enlarged transverse sectionon line 1--4 'oflfig l1;

Fig. 5 is an enlarged det-ail view ot the valve mechanism as disclosed in Fig. 1.

A, indicates the main supply tank; B, in- 50y dicates the auxiliary supply tank; C, the controlling device; and D, the burner. rllhe auxiliary supplyl tank consists of a cylindrical receptacle 1 open at the top, as at 2,

to receive the neck of the bottle or otherl main supplyy receptacle A. The base of the auxiliary supply tank B is recessed as at 3,` having arranged 'immediately above a heavy netting or screening L1, which rests on flange 5 of the base. 6, indicates a heavy cloth placed immediately above the screening t; and 7 indicates a filtering medium 'preferably consisting of cotton-batting or other similar material` placed upon the cloth 6.

The oil controlling device C' preferably 'consists of a base 8 formed into compartments 9 and 10, the compartment 9 being -connected to the recess 3 of the auxiliary tank B by feed-pipe 9. Arranged above the base 8 is a cylindrical chamber 11. An lnlet port 12 communicates between chamber 11 and the chamber 9, and outlet port 13 communicates with the chamber 11 and the outlet chamber 10. The inlet port 12 is` preferably provided withoa removable valveseat 14. 15,v indicates a valve-stem carrying on the lower end thereof a ball-valve 16, which is adapted to normally seat against the movable valve 111. The cylindrical cham ber 11 is provided along itswalls with dia.-

metrically-opposedguide strips 17 arranged lvertically thereof, which are adapted to receive the float 18 and prevent the latter from rotating. rlhe float may be made of any suitable material, such" as cork. threaded collar orV tube 19 is inserted centrally of the iioat 18, and is threaded so as to receive the valve-stem 15, the oat servmg to operatethe valve 16 to close the port 12 when a certain predetermined amount of oil has been received in the chamber 11.

As a means for adjusting the height of the Aloat, the valve-stem 15 is provided with a squared portion 20, which is received in a similarly squared opening 21 in the lower disk 22 'of the cover, the cover preferably being' constructed of spaced disks 22, 23,

f the upper disk 23 being provided with an opening to receive the valve-stem 15. When it is desired to cut oit the flow to the burner, entirely, a knu'rled nut 241' received upon the valve-stem 15 is screwed down tight-ly against the upper disk 23 of the cover, thereby permanently closing the valve 16.

Thus itwill be seen that by turning the cap or cover to the right, it will raise the float, increasing the oil level and correspondingly increasing the lame, and by turning the cover't. the left to lower the float, re-

-ducing .the oil level and correspondingly refducing the flame; When'` vlowering the lloat lsoy as.l toreduce the flame, with the construction as shown in the'accompanying drawings, the flame will temporarily be increased, butl in'justa few seconds it will consume the Asurplus oil and settle down to its normal .s1ze.

Lading end adapted te receive a T-26,'one end of which is adapted to receive-thehorizontally arrangedA hollow tube 27, l.which communicates with ,the annular groove 28 in the burner 29 thereby providing a vaporizing chamber inl the orizontal portion of the pipe, where it enters the burner.

As a. means for restricting the flow of oil from the feed lpipe to the burner 29, the tube 27 is provided with a plug' 30 having oppositely-disposed slots 31' and 32, the slot 32 serving 'to check`the flow of oil so that a higher level may be maintained Awhere the oil enters the slot than in the burner itself. 'As '-a consequence there is .always a' little pressure of oil against this slot, and this gives the float some latitude ,to work on, the slot 31 serving as an air-vent to prevent possible syphoning of the vfeed-pipe 25,... As a means for ,cleaning the slots 3l and '32 of the plug30, the opposite" end. of the T'- 26 isprovided with a. movable plug 33,. whereby the proper cleaning instrument may,

be run through the slots or the plug -entirely removed. for.y cleaning. lt is obviousl that the plu may be provided with lmerely one slot, pre erably the' lower one, made deep enough to perform'thedoublefunction of acting as a feed and vent. 'As indicated in dotted lines, the burner proper is placed at v adjacent the burner. .1t is obvious that a drain-cock or other regulated outlet at this 'point would sudice for the same purpose, and therefore l do not wish to be limited to the exactdetails of such an arrangement. I

By this construction l eliminate the possibility ofthe loil being vaporized in the operation of .the pipe adjacent to lthe burner, thereby reducing the possibility of the dame going'out in case the pipe is exposed to the cold. Furthermore, by my construction, the supply canbe cutl ed at the float chamber,

from base 8 of the control' device is a feed-pipe 25 having an upturned placed in position, the oil turned on at thev float, and the burner `leitto operate, knowing that it will settle down to identically the -same flame at whichit was previously burn-4 ing, as the shutting ed ofthe oil wlth this construction does not change the adjustment of the float orV the oil'level.

Thus it will -be seen that with the co-operation of the several features disclosed l( have produced a purely automatic burner, which 1s reliable in every respect, and .one which needs little, if any, attention after nonce .properly adjusted.
