To all whom it may concern. Y
Be it known that I, CHARLES A. CYPHERS,
a citizen of the United States, residing at Buffalo, inthe county of Erie and State of New York, have invented certain new and useful Improvements in Thermostats; and
I do hereby declare the following to be a full,
clear, and exact description of the same,
reference being had to the accompanying drawings, forming a part ofthis specification,
' and to the figures and letters of reference marked thereon.
This invention relates to thermostats and more especially thermostats designed for controlling or regulating the temperature of artificially heated compartments such as the hatching chambers of, incubators or the a wide-range of thermostatic action, sensij- I ture and brooding chambers of brooders. A The objects of theinventionareto provide a thermostat of compact construction with tive to slight variations in temperature, responding uickly to any change in temperabeing formed with longitudinally extending corrugations registering or nesting with each I other to permit the members to lie close together. v
The invention .further -contem lates a thermostat composed of a series of u licate sections, the corrugations of the a jacent members of the difierent sections registering or nesting together centrally while the corrugations of the members in each section reglster or nest together remote from the center.
The invention further contemplates amember for thermostats having a substantially fiat central part and end parts with lon.
gitudinal corrugations throughout the member intermediate said flat portions. I
The invention consists in certain novel details of construction and combinations and arrangements of parts all as will be now denally rigid to any pressure app out particularly in the ap ended cla1ms.
n the accompanymg drawings-Figure 1 I is a perspective viewof a. thermostat embodylng the present improvements.- Fig. 2 is a side elevation of the same. Fi .3 1s a section'on the line 3 3 of Fig. 2. Fig; 4 is a' section on the 'line 4 4 of Fig. 2. Fig. 5 is a section on the line 55 of F g.2, Figs. 3, 4 and 5 being drawn to the same scale.
Similar letters of reference in "the several figures'indicate like parts.
' In the drawings, the thermostat is shown without the damper or devices to be controlled by it although the operating connec-' tions are shown in the form of a connecting rod A extending centrally-through the members of the thermostat and adjustably connected with or having an adjustable bearing a" engaging the lower member, while an-adjustable tubular supporting device B is connected with the upper member The action of the thermostat causes a relative move ment ofthe parts A and 'B' which may be.
utilized as usual to operate any suitable heat controlling devices. such as a damper, a valve or a flame regulator as heretofore.
In the preferred form the thermostat is made up of three sections D, E and F, the number of sections, however, being purely arbitrary, although the invention, as wil presently appear, has, in part, to do with a construction whereby a number of sections To reduce the. thickness of the sections.
both individually and collectively and alsoto make a rigid structure the members are corrugated longitudinally throughout their width and the corrugations register and nest together where the members approach each other, thus the central members are corrugated as at i throughout their length save for.
cross section and in these parts the necessary slight flexibility or bending takes place during the thermostatic action of the device. Intermediate the fiat portions, the members are rigid by reason of their corrugated form,
' thus the material may be very thin so as to be, quickly affected by changes of temperature of the surrounding air.
It will be noted that the bowed sections are duplicates in-that both may be struck up in the same dies and in assembling them, it is only necessary to bow one in one direction and the. other in the opposite direction, the bending taking place in the narrow flattened parts at the ends and centers.
The width of the strips from which the members are formed is preferably uniform from end to end but the metal is drawn in in the corrugated parts thereby having the flat parts in the completeformation somewhat wider. 'Ihis construction insures a uniform distribution of the metal and re'sultsin a device having a uniform and regular action.
The sections are secured together centralllylr as by rivets K and it will be noted that at t e points where members of adjacent sections approach each other the corrugations register, thus the complete thermostat may be made up of a large number of sections without becoming springy or elastic and will occupy but a minimum vertical space.
While rivets are shown as the fastening means for securing the members together in each section and for securing the sections themselves together, it is obvious that other well known fastening, means may be em-v Having thus described my invention, What I claim as-new and desire to secure'by Letters Patent, is
1. In a thermostat, the-combination of a substantially straight member and a bowed rugatrons registering in scribed.
2. In a thermostat, the-combination with a straight member corrugated longitudinally throughout its width, of a bowed member socured rigidly to the straight member at the ends and having longitudinal corrugations registering with the corrugations of the straight member; said members having different coeflicients of expansion and the bowed member being adapted to bend intermediate its ends when aflected by changes in temperature; substantially as described.
3. In a thermostat the combination with an intermediate straight member corrugated longitudinally, of bowed members having a different coefficient of expansion therefrom located on opposite sides thereof and secured rigidly thereto at the ends, said bowed mem bers having longitudinal corrugations registering with the corrugations of the straight members and being adapted to bend intermediate their ends when aflected by changes in temperature; substantially as described.
4. In a thermostat, the combination of a plurality of sections, each composed of longitudinally corrugated substantially straight and bowed members. secured together, said straight members having a coefiicient of expansion different from that of said bowed members, the corrugations of the members and sections registering with each other in proximity to the points of union and the bowed membersbein adapted to bend intermediate their en s when affected by chan es in temperature. I
5. In a thermostat, the combination of a plurality of sections, each composed of straight and bowed members having diflerent coefiicients of expansion corrugated longitudinallythroughout their width, the corfgroximity both to the points of connection etween the members of the sections and to the points of con-' nection between the sections and thebowed members being adapted to bend intermediate their ends when affected by chan es in temperature; substantially as described.
6.- Ina thermostat, the combination of a plurality of sections secured together centrally, each section being composed of a straight andtwo bowed members secured to opposite sides of the straight member adapt-, -ed to bend in action and having a different coefficient of expansion therefrom, said members being corrugated longitudinally and the corrugations registering in proximity to the points of union between the members; substantially as described. 1
7. A thermostat member formed up from an elongated strip of sheet metal of substantially uniform Width, said member having a central substantially fiat portion capable of bending transversely of the member and end portions longitudinally corrugated throughout their yvidth and merging into thecentral 10 flat portion whereby the end portions are stiffened and the'bending in action confined to the fiat portion of the member; substantially as described.
