14 Claims; (CI.;.219-45) This invention 'relatesito a flxture for holding infra-red lampsf'or use particularly in chicken or SAFETY :FIXTUREFQB- BBOODERS Milton V. LSchubertQJL; Billy E. Langohr, and

Joseph B'. Manage, Jr., Columbia City, and Lorin J. Badske'y,' North Manchester, '-Ind., as- :signors to LML Engineering & .Manufacturing :Corporation',.'0olumbia City, 1nd, a-zcorpoitation The inventive concept includes in such *a'fixture*means'foreuttingoff the'flow of current to all of thelamps carried bythe fixture in the event 'thatthe larnp fixture drops under any cause. I

The infraredlamps have to be xp p ticularly over their outer surfaces, so that the rays may travel'therefrom' to the litter to radiate the heat in the pattern desired.

The fixture herein shown is quite similar to that shown in'the co-pending application serial No. 244,234, which issued on July 15, 1952 .as

:Patentj'No. 2,603,738 wherein-three of the co-.in-

.ventors ,named in this V application are the in- Mentors named in the co -pending application.

fll'heinventiye concept further embodies a very simple :structure wherein thefixture is required to" be:,.tilted.onto its side when .it falls'to :break thescircuit throughthe lamps,i-so that the lamps in-anyevent do not come downonto the litter :with their greatest area in contact therewith. "*These and other objects-and advantages of the invention will become apparent to those versed in the art in the :following description OFOIIGT particular form, ;-in which, referring to the accompanying drawings, I

- Eigs' 1. j is .a .view .in, side elevation and partial section. of a structure .embdoying the invention; E'ig .52 isia wiringdiagram; Figi'3 is a bottom plan-wiew'yand i Fig. 4 is a View in bottom plan of the cover with the lamp mounting base removed.

Azcover l0, generallygofidisk and planar .shape with a .Tdownturned. roundedzflang'e l l is' pro'vi'ded, and to the underside of this cover in there is secured a lamp mounting base l2. This lamp mounting base 12 is of sheet metal, and in convex shape as viewed from the underside.

In the present showing, four infrared lamps l3 are carried by the base l2 through sockets I4.

By reason of these sockets l4 being mounted on the convexbase [2, the axes of the lamps [3 are directed outwardly-one from the lather, substantially coinciding with the radii of cnrv af ture of the baseplate t2,

spacedapartaround the base [2. V

The base I2 -'s b" ought-into contact Wit; the underside of theflco ver' lfl *bymeam qf an outer flange l5. The'fia-ngefl 5'issecured to {the cov l0 byany suitable manner, herein-she by means ofthehook bolts 1 5' I g p M a suspending chain 11 eng ge'd-therewith there being-three'of these hooks,"and"three br riches l8, l9, and 2l,-'exten'dlng firom1the =chai I to engage with thesehook bolts [-6.

On the topside of thecover l0; -*where1 mmediate access thereto "may be-"had ithere js mounted a' thermostat element 22"which; through expansion and contraction in response to temfperature changes, operates' a switch j-Etzf, is

switch '23, n 'the *form herein-shown, operates to cutin and cutout two of thelanips ttgwhile the other two lamps remain: in the, ,circuit' nor- ,nn ly he l ut u of "th 'heat rom'ft es lamps being regulated in thatmanner.

Within thespace fZfi between the base "I "d the cover H] "thereiis mounted a "mercury switch 25, removably carried therein by means or the lower and upper spring clips zfiqand"l'ljrespec tively. These clips; 26 and 2] :a're' carried 'bya bracket 28 inturn'mountedjon the undersidefof the cover Hl, substantially 'centrally locatedfin respect "to the 'cov'er myrne mercuryffswitch 2511s of that'fi type "'whichwhe'n in its yerticajl position,"as indicated in Figs. flfandj his normally inrclose'd circuit condition. Whenthe switchfzfi is tilted 'to one side, :that circuit is interrupted by the'iflow :0ffIIIGIfCl1IfYIfWithlDLthE switch. L' S i n ce this particular .type of switch isoominerciallt obtainable, the details thereofarenot herein .il-

lustrated or described. ,As.indieated. in .Eig.},2, this switch 25 .placed tin the ,circuitso that when it is open all'of the lamps 13 will be deenergized, .regardlessof the condition ofgthe switch-.23 evenithoughit be closed. A rod 3!] is mounted 1011312115 base 11:2 zitoli exten'd ccentrally therefrom :and verticallydownwardly .asiindicated in ,zFig. l1. This rod Bfluhigs ii ggg sufiicient to cause the cover [0 to rock over on its side or rather onto the flange II, should the chain I? break or accidentally become disconnected from its hanger (not shown) to allow the entire fixture to drop. Otherwise the fixture could drop so that it would be supported in that manner by the floor lamps [3 to have the cover ll) substantially horizontally disposed,

TENT

whichin tur e 3 in which case all the lamps 13 would be in con tact with the litter.

However, by reason of the presence of the rod 30, the cover I0 has to rock to one side of the horizontal, and regardless of which direction it may fall the switch 25 will open and thus cut off the current to all of the lamps I3 so that even though the outermost rims of the lamps [3, not over two of them in any event, come into contact with the litter the lamps will cool ofi before the litter has been brought up to the temperature of ignition. While the dimeter of the rod 36 may be quite small, its length should be preferably at least equal to the length of the diameter of the cover 10. The overall length in any event, would have to be limited by the initial, minimum spacing desired between the lamps I3 and the litter, this spacing generally being on the order of from two feet to two and one half feet, and after a certain initial number of days-oi brooding, then the cover l0 and the lamps 13 may be gradually spaced an increasing distance from the litter.

Therefore it is to be seen that we have provided an extremely novel, and yet most emcient device, for the purpose intended, and while we have herein shown and described the invention in the one particular form, it is obvious that structural changes may be employed without departing from the spirit of the invention, and we therefore do not desire to be limited to that precise form beyond the limitations which may be imposed by the following claims.

We claim:

1. A brooder heater device for suspension bove the floor, comprising a heater unit; a member .for carrying the unit; an electric circuit including said unit; a rod carried by said member to' extend downwardly therefrom; and a switch in said circuit carried by said member, said switch being characterized by being in closed circuit condition when said device is in its suspended position and automatically going to an open circuit condition in a tilted position of the device as may be induced by said rod contacting the floor upon release of the device from its suspended position.

2. A brooder heater device for suspension above the floor, comprising a heater unit; a member for carrying the unit; an electric circuit including said unit; a rod carriedby said member to extend downwardly therefrom; and a switch in said circuit carried by said member, said switch being characterized by being in closed circuit condition when said device is in its suspended position and automatically going to an open circuit condition in a tilted position of the device as may be induced by said rod contacting the floor upon release of the device from its suspended position; said member including a base; said heating unit comprising a plurality of heat lamps mounted in circumferentially spaced relation around said base and directed downwardly; said rod being secured centrally of said lamps to said base; and the diameter 6 ofsaid cover exceeding the diameter of a circle including the outermost portions of said lamps,

4 the length of said rod being at least equal to the diameter of said cover.

3. A brooder heater device for suspension above the floor, comprising a heater unit; a member for carrying the unit; an electric circuit including said unit; a rod carried by said members to extend downwardly therefrom; and a switch in said circuit carried by said member, said switch being characterized by being in closed circuit condition when said device is in its suspended position and automatically going to an open circuit condition in a'tilted position of the device as may be induced by said rod contacting the floor upon release of the device from its suspended position; said switch consisting of a mercury tube switch mounted on said member to have its axis vertically disposed in said cover suspended position, whereby said switch is operable to its open circuit condition in all directions of tilting of the cover.
