TIME-CONTROLLED THERMOSTAT'IC' Moron.

Specification of Letters Patent. Patented Allg. 17, 1915.

Application filed July 12, 1909. Serial No. 507,072.

To all 'whom it may concern Be it known that I, EDWARD S. HALSEY,

of Lynn, in the -county of Essex and State of Massachusetts, have ini-ented certain new and useful Improvements in. Time-Controlled Thermostatic Motors, of which the following is a specification.

In carrying out my invention I employ a clock with a time escapeni'ent, adapted to release, at the desired predetermined time, a

tension ligament that leads from the lthermostatic control to and operates, the heaters dampers, or temperature dominating valves. And is designed especially to restrain or cut out of operation a class of thermostatic devices which `are motors of sufficient power and sensibility to be used to operate directly through a rod or ligament, a distant dominating heatvalve, such as, the thermostatic motor described in my Patent #916,861 of March 30th, 1909, which inotoi' has been chosen to illustrate this application.

The object ofmy present invention is to provide a simple eifective means of siinul taneously disengaging the control of the da v motor thus checking-the .fire during the night; by a suitabletiming device, that will throw said motor into commission again at a predetermined time in the morning and further to-provide that while the lire is checked up, it may be engaged with and under the control of another'motor designed to 4hold the temperature to a lower degree.

In the accompanying drawings, Figure 1 represents a front elevation of my apparatus. Fig. 2 represents a similar view on au enlarged scale ofv the same. Fig. 3 representsa Aside elevation of the same. Figs. i and '5 represent respectively front and rear views on a still larger scale of the time-1re- -leasiiig device. Fig. 6 is a side view of said device, while Figs.7 and 8 ai'e respectively,

fractional back and side views of the mechanism, showing the sliding operating rod raised and hooked up to the time releasing stem of the clock. Fig. 9 is a sectional view looking down on Figs. 7 and S the section being made directly at-the top of the clock. Fig. 10 shows the back arrangement of the clock when removed from the supporting Now to go into detail The clock is a small round time piece with a time-set escapement located in the back portion of its case, as is quite common. To serve my purpose, the clock has the winding stem 1, of the time escapement, extended ,so as to project a shortdistance through the clock supporting metal back-plate 2. As is common in these small .metal clocks, in the back a recess is formed, for the winding and set keys, by the extension of the shell of LAthe' case. In this recess a winding key 3 is fixed on said stem -1,'each end of said key is recessed for the stop pin 4,' which is fixed to the back of the clock, so that said keyand stein can turn one-half revolution and no more and when wound up against said stop pin in the position shown in Figs. 7., S, 9 and 10, the top side of said stem is so formed or notched that the yoke 18 which is soldered to the vertical sliding rod 6, can bel hooked up on it, as shown in Figs. 7, 8 and 9, but'at the time the escapement takes place the winding Istem unwinds oiie-lialf turn when the other end of the key strikes the stop pin, and the notched side of said stem,`

looks down while its slanting face looks'np as in Figs. 6 and 7, thus unhooking and letting fall the supported sliding rod `6 with the attached damper operating ligament 7.

. It should beunderstood that the thermostatic-motors D and N used to illustrate :this

rod G is raised and the crossfbar hooked onV the steml, the temperature-controlling damper is operated directly b y the night thermostat through the time mechanism .and the chain 7 attached to the i'od (i, thechain 9 being then slackened and the day thermostat being out of commission for the night. It should now be obvious that with the clock supporting frame 2 supported and carried by the divergent chains S from the night lthermostat N, and with the sliding rod (3,

linking ligament 9 leading from the day thermostat D to the checkdaniper through ligament 7 when the esca )ement stem is Wound at night'or other timeJ and rod 6 is hooked up to rit, chain 9 is slackened and the `day thermostat thrown out of commission,

i while the damper and connecting-rod 6 are moved .up and down With the-.Whole time mechanism, by the then controlling and supis liberated from sired nor lprovided the time releasing mechanism may be rigidly supported by being i Fig. 3, in lwhen rod 6 is hooked up the heater is checked, but there is no thermostatic control until the rod is liberated and l the load again falls onthe single day thermostat as shown in Fig. 2,

The clock isv attached to the supporting back plate 2 by hook A12, fixed at the top of the back plate which engages the hole 11 in theupper edge of the clock case frame, -vvith the projecting stem 1 of the mechanism passing through the hole 1 3 in back pl`ate 2, s ecuring it'in position, 'but it can readily be swung forward and -then lifted off thefhook to Wind and set.`

To Cushion the an vof the rod sana at- :tached damper or Weights I may employ the 'two brass, cylinders 14and15 made air tight at l,the bottom by' soldering tothe foot of plate 2 as shown in Figs. 5, 6. and 7, 'said cylinders acting as an air dash for the semiconical, close-hitting ybut frictionless, iexibly mounted, piston heads 16 and 17, mounted `bywire 'stems' soldered to cross yoke 18v which .in turn is soldered to the upper end of rod '6 These dash pots are not absolutely essential and 4may be omitted Without ai'ecting the fundamentalsof the invention. The apparatus as it appears Without them is 'shown in Fig. 3.

I am aware lthat time controlling devices` for starting up a heater in :the morning are notneW.

What I claim iszl. In conjunction With a mechanical thermostatic motor a clock With time set escapement'; an operating ligament leading from said motori-to a temperature dominating valve;"la device releasable by said clock mechanism at 'apredetermined time; for hooking up said operating ligament thereby relieving said thermostatic motor of tension and duty untilreleased by said clock.
