JAMES F. MCELROY, OF ALBANY, NEW YORK, ASSIGNOR TO THE CONSOLI- DATED CAR HEATING COMPANY, OF WHEELING, \VEST VIRGINIA.
TEMPERATURE-REGULATOR.
SPECIFICATION forming part of Letters Patent No. J='71,314=, dated March 22, 1892. Application filed May 1 1891. Serial No. 391,274. (No model.)
.To aZZ whom it may concern.-
Be it known that I, JAMEs F. MoELRoY,-a citizen of theUnited States, residingat Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Ternperature-Regulators, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to new and usefu improvements in temperature-regulators; and it consists in the peculiar construction, arrangement, and combination of the various parts, all as more fully hereinafter described.
In the construction of temperature-regulators heretofore it has in many cases been customary to arrange the thermic cell vertically and arrange the rod connectingwith the cell beside the wall. l/Vith a Vertical arrangement of the cell arrangement of the connecting-rod beside the wall could easily be effected; but it has been found that as good results are not to be had by the vertical arrangement of the cell as with a horizontal arrangement. The objection arises in the horizontal arrangement, however, that if the rod is connected directly to the center of the thermic cell it will extend out quite a distance from the wall, and with the construction which I have herein shown and described I am enabled to use such an arrangement of the cell with the bracket, which allows me to place the rod beside the wall, as heretofore.
In the drawings, Figure l is a vertical central section through my improved temperature-regulator. Fig. 2 is a top plan view thereof. Fig. 3 is a detail perspective View of the stem.
A is the frame adapted to be secured to the wall of the chamber the heat of which is desired to be regulated. This frame is provided at the top with the horizontal extending bracket B and at the bottom with an apertured guide-bearing 0, through which the rod 1) extends beside the wall.
E is a thermic cell containing any suitable eXpansible medium and preferably constructed with two sheet-metal disks connected together at the edges. Upon each side of this cell and secured thereto are the hubs F F. This disk is suspended in a horizontal plane from the bracket B by means of the stem G, extending from the hub F and provided with the segmental circular screw-threads H upon opposite sides thereof. The bracket Bis apertured, and the sides of this aperture are provided with the segmental circular threads I upon opposite sides thereof, with the slots J intervening, all so arranged that when the screw-threads II on the stem are turned to register with the slots J the same may be engaged in the aperture, and when turned in either direction the screw-threads II will engage with the screw-threads I and hold the same in position. It is evident that in turnin g this stem either way when the two screwthreads are engaged with each other there will be a slight vertical adjustment of the cells. To conveniently accomplish this, I provide the hand-lever K, securedto the hub F.
The hub F, I provide with a bolt L, preferably formed integral therewith, which extends through an aperture in the bracket M. This bracket extends inwardly to a point near the frame and is suitably apertured to receive the upper end of the rod D. It is also provided with a downwardly-inclined arm N, which also is apertured to allow the rod to pass therethrough.
O is a lock-nut for holding the rod and bracket in their adjusted relation, and P is an aperture through the rod, by means of which it may be turned to adjust it up or down, so that in setting the device the valve may have the proper vertical adjustment to open and close at the desired temperature.
Q is a spring bearing at the upper end against the nut Q and at the lower end upon the topof the bearing 0. The function of this spring is to hold the valve normally in an open position, and the nut Q is to adjust its tension.
R is a roller=-bearing journaled beneath the guide-bearing O in the frame, adapted to receive the side thrust of the rod D. It will be 5 seen that with this construction I am enabled to get the horizontal arrangement of the thermic cell and yet carry the rod close beside the wall without a multiplicity of parts.
WVhat I claim as my invention is-= 1. In a temperatitre-regulator, the combination of the frame, a horizontally-arranged ter of the cell and said bracket, substantially as described. i
3. In a temperature-regulator, the combina tion of the frame, the thermic cell, a bracket connected to said cell, a connecting-rod extending to the valve to be operated, arranged to one side of the center of the cell, and a screw-threaded engagement between the rod and bracket, whereby the rod may be lengthened or shortened by turning" it Within the bracket, substantially as described.
- L. In a temperature-regulator, the combination, with a frame, the thermostat, and the con 11 ecting-rod, of a stem on the thermostat, havin g segmental screw-threaded portions, and a socket in the frame, having corresponding segmental screw-threaded portions with intermediate slots, substantially as described.
5. In a tem peratnre'regulator, the combination, with a frame having a bracket thereon, of a thermic cell on the bracket, a bracket secured to the cell, having a downwardly-extending arm N, and avalve-actuating rod adjustably secured in said bracket, substantially as described.
6. In a temperature-regulator, the combination, with the thermic cell, of the bracket M, the rod D, having a screw-threaded engagement with said bracket, and means for turn ing' said rod to adjust itverticall'y, substantially as described.
In testimony whereof I aflix mysignature in presence of two witnesses.
JAMES F. MCELROY.
