CONTROLLING ATTACHMENT FQR- HEATING-LAMPS.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed April 24, 1907. Serial No. 370,055.

To all whom it may concern:

Be it known that we, LEWIS W. HOLMES and CORNELIUS V. TRAUTMAN, citizens of the United States, residing at Medora, in the county of Jackson and State of Indiana, have invented a new and useful Controlling Attachment for Heating-Lamps, of which the following is a specification.

This invention relates to controlling attachments for heating lamps such as used in connection with incubators and its object is to provide thermostatically controlled means for increasing or reducing. the size of the flame so that'the temperature within the in cubator may be maintained uniform. I

Another object is to provide-simple and efficient means for adjusting the attachment so 'as to maintain any desired degree of heat within the incubator.

With these and other objects in view the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fullydescribed and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings: Figure 1 is a section through a portion of an incubator and showing the attachment in elevation; Fig. 2 is a plan view of the attachment; and Fig. 3 is a detail view of the flame controlling lever.

Referring to the figures by characters of reference, 1 designates the body of an incubator or the like from which extends a bracket 2 designed to support a heating lam 3. A cross strip 4 is carried by this brac et and has upstanding ears 5 and 6, the ears 5 constitutlng bearings for a rod 7 while the ears 6 serve to revent longitudinal displacement of the rod? 7 at right angles thereto and carries arectangular sleeve 9 which loosely surrounds a burner 10 of the heater 3. Another arm 11 extends in the opposite direction from rod 7 and carries a counterbalance 1 Stop lugs 13 are supported beneath the arms'8 and 11 so as to limit, their swinging movement. ,A bail-like extension 14 extends upward from the rod 7 and is for the purposehereinafter set forth. j

Secured upon the body 1 and above bracket 2 is angular bracket 15 from which extends a guide plate 16 having'inwithin the body 1.

An arm 8 extends from the rod turned flanges 17 at the sides thereof. slide '18 is mounted between these flanges and has an upstanding car 19. A plate 20 extends upward from bracket 15 and slid ably mounted within'it is an adjusting screw 21 which is connected to ear 19 andis engaged by-an adjusting nut 22. A coiled spring 23 is arranged upon the screw 21 and bears at its ends on plate 20 and car 19. Ears 24 extend downward from the slide 18 and bearing within them is the up er end of a lever 25 having a fork 26' at its ower end which loosely engages the bail 14. An eye 27 is formed within this lever between its ends and is engaged b one end-of a link 28. The other end of this engages an car 29 formed at one end of a thermostat30. This thermostat is in the form of a bowed metallic strip secured at one end within the bod 1 and formed of material which will readily expand when heated.

It is to be understood that when the p rts are in their normal positions the wick 31 of the burner is exposed so that the flame will not be confinedor restricted. When, however, the thermostat is subjected to a redetermined heat it will pull inward on lin 2-8 and lever 25 and swing the bail 14 so as to raise arm 8 and sleeve 9. reduce the size of the flame and as the thermostat cools the parts will return to their initial positions. It is obvious that by adjusting the slide 18 the parts can be regulated so as to maintain any desired tem erature By arranging t e arts in the manner shown ,and' describe the movement of the thermostat is greatly multiplied so that a very slight ex ansion or contraction of the thermostat wil cause a considerable movement'of sleeve 9.

YVhat is claimed is:

The combination with a supporting structure and a bracket extending therefrom for supporting ahe'ater; of a cross strip connecting opposite portions of the'bracket, u standing bearing ears thereon between tie ends thereof ,upstanding retaining ears thereon adj acent the ends thereof, oppositely disposed stop lugs integral with the cross strip, a rod detachably mounted upon the bearing ears and held against longitudinal movement by The sleeve will by the free end of said arm, an arm extending as our own, we have hereto afiixed our in the 8p osite Idirection from thg rods 21, signatures in the presence of two witnesses. counter a ance t 1616011, an u stan in ei upon the rod, and a thermostatically? cong gi' 5 trolled lever pivotallyconnected to the t supporting structure and having a forked Witnesses: end engaglng the bail.

In testimony that we claim the foregoing CHAS. V. WEDDELL.
