H. W. RICHARDSON HEAT SPILLER FOR INCUBATORS Filed June '7, 1924 INVENTOR BY A TTORNEY Patented Dec. 8, 1925.-
UNITED STATES PATENT OF F I C E HENRY W. RICHARDSON, OF LITTLE FALLS, NEW YORK, ASSIGNOR T0 PERCY D. PETERS, 0F LITTLE FALLS, NEW' YORK.
HEAT SPILLER'FOR INCUBATORS.
Application filed June 7,
To all whom 2'25 may concern:
Be it known that I, HENRY W. RICHARD- SON, a citizen of the United States, residing at Little Falls, in the county of Herkimer and State of New York, have invented cer tain new and useful Improvements in Heat Spillers for Incubators, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to a heat spiller for incubators, and I declare the following to be a full, clear, concise and exact description thereof sufficient to enable anyone skilled in the art to which it appertains'to make and use the same reference being had to the accompanying drawings in which like reference characters refer to like parts throughout the specification.
The object of the invention is to provide an automatic device for opening up a door or vent in the upper part of the compartment of an incubator to the'atmospherc, whereby to allow for the escape or spilling of hot air, when the temperature in said compartment rises above a predetermined degree.
The object will be understood by referring to the drawings in which:
Fig. 1 is a perspective view of the device, showing the correlated parts of an incubator which is broken away;
Fig. 2is a detailed enlarged view, showing a perspective of a bracket member employed;
Fig. 3 is an enlarged detail view showing a perspective of a wire rod used;
Fig. 4 is a detail view, showing a perspective of the door or spiller and immediate parts;
Fig. 5 is a fragmentary view of the door, showing an inside elevation thereof;
Fig. 6 is a detail perspective view of the door frame and door;
Fig. 7 is a detail View, showing a modification of the door;
' Fig. 8 is a detail view of thermostat used.
Referring more particularly to the drawings, the upper part of the front wall of an incubator is represented by 1. There is shown also a portion of the upper frame 2 to which is attached a fabric 3 forming a partition wall between the compartment adapted to contain the eggs and that containing the pipes. which fabric partition prevents drafts within the incubator. These 1924. Serial No. 718,666.
parts are well known in the construction of incubators and are mentioned merely to show the relation of those parts to the ones which are novel and embody a metallic door or heat spiller 5 made of sheet metal and having centrally disposed laterally located trunnions 6, 6 formed integral therewith. Trunnions 6, 6 are mountedin bearings 7, 7 made integral with metallic frame 8 that is set in an opening in wall 1 of the incubator, whereby said door 5 is permitted to swing upon its trunnions 6, 6 as pivots. Door 5 is limited to swing with its top part outward by reason of the extended upper portions 10, 10 of frame 2 which will overlap door 5 when in closed position and, therefore, prcvent said door 5 from swinging therepast.
A bracket 15 is fulcrumed upon a rod 16 that passes through apertures 18, 18 made in the side walls 19, 19 of bracket 15. Bracket 15 is held in horizontal position or at right angles to the surface of door 5 by a depending or bent overpart 20 which is adapted to abut against the inner surface of door 5 and, thereby, hold bracket 15 in horizontal position. Rod 16 is bent or offset at 12 to engage apertures 18, 18 formed in side walls'19, 19. The ends 23, 23 of rod 16 are bent into circles to allow for the projection therethrough of screw bolts 24, 24 that are mounted to door 5. -Another part 25 of bracket 15 is bent upward to be engaged by l the adjusting screw 26 that is screw mount ed to head or boss 27. Head 27 is riveted to door 5. By adjusting the outer end of screw 26 more or less near part 25, the throw or swing of bracket 15 on its fulcrum, namely rod 16 will be limited in accordance therewith. Door 5 is held normally closed by weight 28 that is mounted on one of the bolts 24 aforementioned. Said bolt projects into the center of said Weight 28.
The outer or free ends of side walls 19, 19 of bracket '15 are equipped, in each instance, with an aperture to form bearings for the shaft 30 upon which turns an. antifriction roller 31 having an annular groove in its peripheral surface.
The free end of rod 40 is adapted to rest against the under surface of antifriction' roller 31. The opposite end of rod 40 is held by a set screw 41 in a recess formed in rock member 42. Moreover, rod 40 has an offset portion at 43.
' i k thermostat; 61 Qf-well known construction is suspended from arm 59 A short Shaft. 62 a te ed t e ower plate- 3 o h m s a 1 s. d pted tol mak fc ntact with eve 6, wh re y t ransfer he expansionot said thermostat, 61 to saidlever, 56. Wire rod 52; that connects, lever 56 withrod .50will. erert, becanseof its hori zontal part 53, a yielding, pnll on thermo: stat 61, whereby tqopenmleor 5,,in. a, steady manner d also be asy. nd effect less strain, on said thermostat 61, whereby t prolong the life thereofg Itwillbe. found that a yielding pull such, above described will not be as'harmful as, a direct pull; on therines tat. 61, for a; direct pull. will cause the thermost t 61 to. lose its. energy. and, hence, shorten the liiethereof. 1
The operation ofthe device, to. maintain a, correct temperature in each compartment of the incubator is eilectedms follows: Door is normally closed, however, should, the temperature within the compartment rise abovethe desired or predetermineddegree, the excess heat. would-be allowed, to. escape by, way of, door or heat spiller 5. Int-hi event, thermostat 61 would expand and; depress. lever 56,. which would; pull,v in, turn; red 52 downward. Rod 52 would,- therefore, exert a pressure on the endof rod50 to rockmember 4:2, and, thereby, elevate the free end of rod 10. The horizontal or extended part 53 of rod 52. will'incr'ease the amount oi leverage, whereby rod 4E0 will respond upon a very slight vertical motion of rod. The. elevation of the free end of'rod 40 will force ant-ii'riction roller 31 and bracket 15 to which it is connected upward, and, thereby, open door or heat spiller 5 by turning the same on its trunnions 6, 6. Immediately, the temperature within said compartment has fallen, the thermostat 61 will: react to allow the, free end. of levers 5G and 50, to. swing upward; and likewise rock member 12 and :rod; 10 to swing downward. lVeightQS on door 5 would cause then said door 5 to return to closed position. Variations in thetemperaturewithin.the compartment of the incubator will. have their corresponding eii'ectupon thermostat 61 which will react to control; the movements of door 5. The degree of opening of door 5 can. be controlled by regulating the adjusting screw 26.
Fig. 8. shows a modification. Here door whichcorresponds todoor 5 of the former construction is hinged at 71, 71 along. its bottom edge rather than in its. center part as is the case of: door 5. A shoulder or. reduced part 72- is formed on three sides of ge 0f 0 0, whereby to make an. air tight fit with, its. frame, when in closed. position, Weight 7 5 ismounted on a U. shaped rod 76that is attached to door 701by screw bolts 77, 77. Said weight..70.is suspended much higher up with relation. to door 70 than weight 28 of door 5, in order to elevate the centerof'gmvity and, thereby, aid said weight 7 5 in closingdoor 70.
Having thusdescribed'my invention what I; claim as new and desire to secureby Letters Patent is: i
1, In ahea-t spiller fol-incubators, a door adapted toopenfor theexit ofhot air from said incubator, thermostatic means for. controlling. thegmovements of said door, and yielding means connecting. said thermostat with saiddoor to aidinprolonging the life of-saidthe 'mostat 2.
