2 Claims.
This invention relates to a damper for furnaces and other heating means, the general object of the invention being to provide thermostatic means for controlling the damper with means for adjusting the thermostatic means whereby the temperature of a building or enclosure heated by the device can be automatically regulated.
This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a fragmentary side view showing the invention applied to a furnace which may be used for heating a tobacco barn.
Figure 2 is a front view of Figure 1.
the bar Ill rearwardly which will cause the link l2 to exert a pull on the arm l2 so as to rock the shaft in a direction to close the damper doors 2, the doors being held in open position when the shaft 4 is rocked in an opposite directionby depressing the arm l extending outwardly from the shaft 4, the arm l5 being provided with a weight l5 so that this weighted arm Figure 3 is a View of the dial for the regulator means.
Figure 4 is a top plan view of Figure 1. Figure 5 is a section on line 5-5 of Figure 1. Figure 6 is a section on line 66 of Figure 1. In these views the letter F indicates a furnace which is provided with a metal front member A which contains a door covered opening, the door being shown at D, the hinges being shown at d and the latch means at b. An opening I is is formed in each side of the metal member A adjacent the lower end thereof and each opening is closed by a door 2 hinged at its upper edge, as shown at 3. A horizontal shaft 4 is supported by the uprights 5 connected with the member A and links 6 are connected with the bent ends I of the shaft and extend downwardly and are connected to the doors 2 so that by rocking the shaft 4 in one direction the doors will be opened, as shown in dotted lines in Figure 5 and the doors will close when the shaft is moved in an opposite direction.
A frame E extends upwardly from the member A and carries a small frame 8 at its rear part in which is arranged a thermostat 9 of the beltends to hold the parts in position with the doors 2 in open position.
The thermostat can be adjusted to close the doors at any desireddegree of heat by a rod I6 having its rear end engaging the thermostat with its front end screw threaded and passing through a nut member ll, the rod having a knob I8 on its front end which permits it to be turned and the rod carries a dial l9 which cooperates with a marker 20 on a part 2| of the frame E for indicating the degree to which the rod must be turned to cause the thermostat to open the doors at the desired degree.
Thus it will be seen that the damper doors 2 will remain open until the furnace heats the barn or other enclosure to the desired degree when the thermostat will act to close the doors so that the interior of the barn is kept at a constant temperature.
As before stated while the device shown is intended for atobacco barn it can be used for different purposes and with but slight change the device can'be used for controlling the temperature of an incubator, brooder or the like.
It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.
It is to, be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.
Having thus described the invention, what I claim is:
1. In a device of the class described, a heating device having a draft opening therein, a door for closing the opening, a shaft supported for rocking movement and having a first arm thereon,
having a part engaging the bar for moving the bar rearwardly, when the thermostat expands, whereby the shaft is rocked to close the door, a horizontally arranged rod supported for rotary movement in the frame and having its rear end engaging the thermostat to adjust the same, a knob on the front end and indicator means for indicating the amount of adjustment of the thermostat by turning movement of the rod.
2. In combination with a furnace having a draft opening in a side portion of its front thereof, a horizontally arranged shaft supported at the front of the furnace for rocking movement, an arm extending rearwardly from the shaft, a door for closing the draft opening and moving downwardly to closed position, a link connecting the door with the arm, a forwardly extending weighted arm on the shaft acting as a handle for moving the shaft and also acting to hold the shaft in a position with the door open, an
upwardly extending arm on the shaft, an up right frame connected with the front of the furnace and having a small frame in its rear, a thermostat located in the small frame, a vertically arranged bar pivotally connected at its upper end in the small frame and engaged by a part of the thermostat when the same expands whereby the bar will move rearwardly, a link connecting the lower end of the bar to the lastmentioned arm on the shaft for moving the shaft to close the door when the thermostat expands, a horizontal rod supported in the upper part of the frame. for rotary movement and having its rear end engaging the thermostat to adjust the same, the front end of the rod having a knob thereon, indicator means associated with the rod and frame and a nut member through which the rod passes. v
