The leverlO is likethrough vice herein, which'will be recognized as extremely simple,

easily operated and not liable to become deranged or out of order.

I will now takeup the description of the thermostatic portion of my device, such being required to actuate said regulatorthe instrumentality of the greater or lesser degree of heat in the heater portion of the furnace. This thermostatic device is composed of a vertical rod 23, a'vertically-adjustable fork 24 having screwthreaded connection with a socket in the upper end ofsaid rod, a hollow or open mouthed contacthead 25 having adjustable screw-threaded connection with the lower end of said rod, a lock-nut 26 for said eontact-head 25, and a detachable pan or receptacle 27 carried by said rod 23 between its upper and lower ends.

theholes 16 at the outer end of the lever 10, said holes 16 being adapted to furnish.

any variations in the assembling of the parts of my device for use. The contact-head 25 at the lower end of the rod 23 is provided by me for the reason that its lower edge is of greater area than that of the rod itself would be'and such greater area enables an increased contact, as well as a surer contact with the upper surface of the crown or dome of the heater, as best seen in Fig. 3. The open mouthor hollow of the contact-head 25' encircles the small nipple or projection 28. that customarily tips'the dome-of an ordinary furnace heater. projection serves as a guide or centralizer for suspending the thermostatic portion of my device over the heater and does not interfere with its operation. The pan 27 forms a receptacle into which a quantity of sand or other like convenient matter is placed to provide a variably-disposed weight on the rod 23 and, also, on the regulator lever 10 to suit the desired adjustment of the entire device. Said pan is detachably secured on said rod by means of a set-screw 27 or the like.

In order to more conveniently use the furnace with my improved regulator device, I provide a very simple connecting-means with an indicator 36 that is located in the apartment above the cellar or basement where the said furnace is located. Such connecting-means is composed of a pair of angular-levers or bell-cranks 29 pivotally mounted at the respective opposite ends of the timber or bar 13, (as best seen in Fig. 1,) a connecting-wire or rod 30, a chain or flexible connection31 leading over a pulley 32 from one of the bell-cranks 29 through an opening 33 in the floor 34 to said indicator the said pinion, in turn,

The upper forked end 2 1 is detachably secured in either one of so as to frequently Said nipple or" mounted. on said bell-cranks 29, over which pulleys the chain 21 is hung and rides in the opening and closing of the several air valves 7 and 9 to suit thecondition of the heat radiating from the furnace 1 and the expansion and contraction of the latter in use.

. In the operation of my improved regulator device, the expansion of the furnace due' to the heat within causes the rod .23 to rise, thereby actuating the lever 10, the latter, in turn, moving downward at its arc-formation 15 end and causing the pinion 17 toturn;

causes the crankarm 19 to move, whereby the chain 21 rides along the pulleys 35 against the heft of' the weight 22 and allows the draft-lid 9 to gravitate gradually and slowly toward'the draft-opening 8 for closing or otherwise limiting the amount of air passing into said 0 ening 8, and, also, raising the check lid or amper 7 for admitting air to the smoke pipe or flue 4; the" said lids or dampers 7 and 9 alternately close and open to suit the amount of 'air to pass into the flue or into the draft opening, as occasion may require in the regulating of the furnace for greaterv or less heat, or uniform heat in' the apartments above; the indicator 36 in the apartment above will show thereon just what position the regulator and the dampers are in,

save the operator a number of trips to. the basement or cellar below where the furnace is ishing of, or other attention to the fire-and the furnace. The weight 22 serves to automatically return the damper 7 to closed or closing position and to raise the draft-lid 9 to open position when the toothed sector 15 has moved upward and, also, when the thermostatic device has returned to its downward position ready for action upon even the minutest expansion of thedome of the heater.

I claim 1. In a heating apparatus having air check and draft valves, a regulator device comprisinga pivotally hung lever havin a toothed arc-formation at one end thereo a 36 in said apartment above. Pulleys 35 are located in the replen pinion journaled in co-acting relation with rod, a variably-connected fork provided at actuating-arm plvotally-mounted in relation with the heating apparatus and variablypansion and contraction of the contacting part of the heater causes the desired movements of 'said actuating-arm of the regulator.

3. In a heatingv apparatus having air check and draft devices, a thermal device I flexibly-connected tov said air check and draftdevices and having at its lower end an open-mouthed contact-head adapted to engage the tip oflthe heater dome, a variablyattached fork at the-upper end of the rod forming a part of said. thermal device, a Weight pan or rece tacle carried by said rod and adapted to re eive sand or other loose contents capable of variable heft therein.

4; In a furnace-regulator, the combination with an arm or lever carrying a toothed arc-formation at one end thereof, a pinion engaging said arc-formation, a crank-arm connected with said fork, whereby the exconnected to said pinion to coiipe'rate therewith, a flexible device connected vto said crank-arm and riding over suitable pulleys for connection at its opposite ends with the air check and draft dampers of the furnace,

bell-cranks carrying said pulleys, a rod connecting said bell-cranks, a flexible connection between one of said bell-cranks and a suitable indicator located in the apartment above the chamber occupied by said furnace and thermal means between said arc-formation-lever and the heater for-actuating both 3 the regulator and the indicator.
