To all whom it ma y concern:

Be it known that I, ROBERT T. GARRETT,

a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania,

have invented certain new and useful Improvements in Time-Regulators for Dampers of Furnaces, Ranges, or Stoves, of which the following is a specification.

My invention relates to means to manually set a time regulator for the damper of I av furnace, range orstove to control automatically by a clock-mechanism actuation of means affecting the vfire mass of the furnace, range or stove; and in such connection my present invention relates to the particular arrangement of the time regulator for the defined purpose, as hereinafter fully described and claimed.

The nature and scope ofmy present invention will be more fully understood from the following description taken in connection with the accompanyingdrawings forming part hereof, in which- Figure 1, is a side elevational view of a furnace provided with a time regulated damper and clock-mechanism as a part thereof, suspended from the rafters of a cellar or other room, the time damper regulator being manually set, and then controlled as to its actuation by the alarmmechanism of the clock, for operating the dampers, to respectively open and close the same and embodying the main features of my said invention. Fig. 2, is a broken sectional front elevational view on the line w-w of Fig. 3, with the face-plate of an ordinary alarm clockremoved. Fig. 3, is a vertical sectional view through the clockmechanism, showing the face-plate, hour and minute hands, the chain and weight winding means and the grooved pulley on the back of the clock secured to the shaft of the alarm-mechanism and over which the the spring controlled shaft of the alarm-;

mechanism, and also showing the cord attached to, said pulley and the draft damper and the opposlte end having a hand-hold to manually operate for permitting of the opening of the damper through the setting of said alarm according to the time the chimney or draft damper is to close. Fig.

6, is a broken sectional side elevational view of therange chimney damper in a closed position with the cord from the pulley of Fig. 5, in connection with the damper; and Fig. 7, is an end view in broken section of the grooved pulley, showing the cord and screw for securing to said pulley in the manner, as illustrated, in side view in Fig. 5.

Referring to the drawings with particular reference to Figs. l-3 inclusive, 0; is a furnace of ordinary well-known construction having a damper door a located to one side of the draft-pipe a to the chimney flue, and having an ash-pit damper door a 6, is a clock'suspended, as shown, from rafters 6 of a cellar or other apartment in which the furnace is located. The clock as shown is provided with a chain 5 carrying a weight 5 This chain is for manually winding the main spring controlling the hour and minute hands of the clock and which clock is also provided with an alarmmechanism 6', Fig. 2, having a setting hand 5 Fig. 1. This clock represents the wellknown Ingersoll or Waltham alarm clock. On the rear of the shaft 6 of the alarmmechanism 6, is rigidly mounted a large grooved pulley wheel 5 having stop-pins 6 and 6 as illustrated in Fig. 5. The shaft 6, is provided with a coiled leaf spring 22 The said shaft is journaled to a rightangular bracket 6 which is secured to the back-plate of the clock 6, and with which bracket the stop-pins b and b, respectively engage the upper part 72 of the bracket 5 when the damper is open and the lower part b, of the bracket 6 when the damper is closed.

The grooved pulley wheel 6', carries a cord 72, as shown. One end of the cord 6, is connected with-the ash-pit damper door a and passes over a series of guidepulleys 6", depending from the rafters and which cord carries a weight 5 above the connection of the other end of said cord with the draft-damper a In dotted outline is shown in Fig. l, the open position of the draft damper. The hook b is provided at the opposite end of the cord b", to attach to an eye 6 to the right provided in the ash-pit damper door a as shown in Fig. l, for permitting of the opening of the same. To operate the time regulator under the damper arrangement of Fig. 1, when the draft damper a is to occupy an open position, it'is necessary only to manually operate the cord 6 to set thedampers a and a The clock is now wound up manually by the weighted chain bfland therewith the alarmmechanism set by hand to permit the said alarm at a particularhour to go off'and to actuate the 'springcontrolled shaft 6 carrying the large grooved pulley If, to thereby cause the same to revolve and the stop-pin b, to engage the bracket 6", to thereby hold the said pulley from further movement, at which time the draft damper a is'closed and the ash-pit doordamper a is opened.

In Figs. 4 to 7 inclusive, the time damper regulator is illustrated in applicationto a range in which one end of'the cord b, is attached to the draft regulator damper a of the chimney flue and the oth'er'end beyondits fixed connection with the grooved pulley wheel I), is carried and operated by the springcontrolled shaft b of the alarmmechanism 6 of the clock I). This cord 6 is provided with a hand-hold'b for drawing the same outward to elevate the regulator damper a to the extent desired, and at the same time to wind the alarm-mechanism b of-the clock I), at such hour as that the tripping device 6 of said mechanism,

as illustrated in Figs. 2 and 3, can cause the Copies of this patent may, be obtained for five cents each, by addressing the Washington, D. 0.

alarm, to go off under the action of the wound up main. spring of the clock, as will be readily understood. The'winding is acc mp i d m nua ly by hecu igh chain bflwhich chain passes over a sprocket-Wheel 22 asillustrated in Fig. 5. The stop-pins b and b, respectively, limit the extent of 'movement of the said pulley-wheel b", of the spring controlled shaft 6?, of the said alarm-mechanism bflin the winding and also in the reverse movement of the said pulley-wheel, when the'alarmi is-to go off, at aparticular selected time. s

Having thus described the nature and objects of my invention, what I claim as new and desire to secure byLetters Patent is In a time regulatordamper for furnaces, etc., a clockhaving an alarm-mechanism provided with a spring controlled shaftand a tripping-device, a pulley-carried on and operated by said shaft, flexible weighted means connected with said pulley tocontrol the dampers and to permit of winding of said-mechanism, a bracket secured to the Commissionerof Patents,
