UNITED STATES PATENT OFFICE.
JAMES EMCELROY, OF ALBANY, NElV YORK, ASSIGNOR TO THE CONSOLI- DATED OAR HEATING COMPANY, OF W'I'IEELING, \VEST VIRGINIA.
TEMPERATURE-REGULATOR.
*GI-ECIFIOATION forming part of Letters Patent No. 462,503, dated November 3, 1891.
Application filed May 14, 1891. Serial No. 392,747. (No model.)
.To all whom, it may concern.-
Be it known that 1, JAMES F. MCELROY, a citizen of the United States, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in a Temperature-Regulater, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to new and useful improvements in temperature-regnlators and it consists in the peculiar construction of the actuating mechanism designed to transmit motion from the thermostat to the device to be operated, such as the valve or damper.
The invention further consists in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described.
In the drawings, Figure 1 is a front elevation of my improved device. Fig. 2 is a vertical central section thereof. Fig. 3 is a crosssection on line 00 at in Fig. 1.
A is the supporting-frame provided with suitable means for attaching it to a wall in a room or car in which the temperature is desired to be maintained at or near a fixed point. This frame is provided at its top with an outward-extending frame or bracket B, to
0 which are pivoted the depending levers C C. Between these levers is a thermostat of any desired construction, that which I preferably employ being shown in the drawings, and consisting of an expansion-chamber formed 3 5 by two circular disks secured together at the edges and containing within any suitable expansible material. I preferably use some material which will vaporize at or about the temperature desired to be maintained. In the 0 drawings, I have shown two of these expansion-chambers D D separated at the middle by a block E and having secured to each side blocks F F, giving a wide bearing for the disks to bear against as the material within 5 expands. These blocks or hubsF F are provided with screw-threaded stems G G, respectively, which are oppositely screwthreaded and engage in correspondingly,
threaded apertures in blocks H II. These 3 blocks are provided with pintles I on the side,
which enter suitable apertures in the levers.
The levers are made in two parts ab, secured together by means of bolts or screws 0, which clamp the blocks II 11 between them, the halves of the levers being centrally recessed 5 5 to allow the insertion of the blocks, as plainly shown in Fig. 1. .I J are pivots upon which these levers turn.
K is a lever secured to one of the blocks or hubs II II, extending to the side of the frame and so arranged that it can be turned up or down to adjust the levers to or from each other by turning the screw-threaded stems in the blocks. At the lower end these levers connect to a connecting-rod K by means of toggle-levers I1 and cross-head M. This connecting'rod extends to the valve or damper to be operated, which valve or damper is held normally in a certain position by the action of a spring N, bearing at one end against the guide-bearing O of the frame and at the other end againstthe nut P, adj ustably secured upon the rod K. The expansion of the thermostat will separate the levers C O, and through the toggle-levers L will move downwardly the connecting-rod K, overcoming the tension of the spring N. As the heat in the room increases and the thermostat continues to expand, it will-bring the levers L more nearly to the vertical position, increasing the power in proportion to the amount of expansion. This is especially desirable in high-pressure steamheating apparatus.
It is evident that my thermostat and the actuating-levers may be inverted from the posi- 8 5 tion shown in the drawings, and the togglelevers may be made to incline toward the actuating-stem instead of from it, so as to lift the valve to shut it instead of moving it downward, as would be the case in the construction 0 illustrated.
The object of pivoting the blocks II II to the levers is to prevent any strain upon the thermic cells due to change in angular position between such cell and the levers.
W hat I claim as my invention is- 1. In a temperature-regulator, the combination of the frame, a thermostat, two levers between which said thermostat is secured, and connections from said levers to the device to I00 be operated, substantially as described.
2. In a temperature-regulator, the combination of the frame, a thermostat, two levers between which said thermostat is secured, a connecting-rod, and connections between said levers and the rod, substantially as clescribed.
3. In a temperature-regulator, the combination of the frame, a thermostat, two levers between which said thermostat is secured, a col'lnecting-rod, and toggle connection between said rod and levers, substantially asdescribed.
etnln a temperature-regulator, the combination of the frame, a thermostat, two actuatlug-levers on opposite sides of the thermostat, a connecting-rod, a head on the rod, and toggle-levers connecting the head and actuating-levers, substantially as described.
5. In a temperature-regulator, the combination of the frame, two levers pivoted thereto, a thermostat secured between said levers, and right and left hand screw-threaded stems on said thermostat engaging with said levers,
substantially as described.
6. In a teinperature-regulator, the combination of the frame, the thermostat having side projections, and the levers on opposite sides of the thermostat composed of two parts clamped upon said side projections, substantially as described.
7. In a temperature-regulator, the combination of the frame, the thermostat having screw-threaded stems on opposite sides, the blocks with which said stems engage, and the levers on opposite sides of said thermostat, to which said blocks are pivoted, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
