UNITED STATES PATENT OFFICE.

JOSEPH E. WINTERBOTHAM, 0F WINNETKA, ILLINOIS.

DAMPERfCONTROL MEANS.

Application filed April 14,

Be it known that I, JOSEPH E. WINTER- BoTHAM, a citizen of the United States, ref siding at Winnetka, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Damper- Control Means, of which the following is a full, clear, and exact specification.

This invention relates to damper control means or mechanism, and more particularly to such mechanism whereby effective action thereof is timed.

I am `aware of the fact that there are many devices of a similar nature on the market, but in each case the mechanism is comparatively complicated and correspondingly expensive. At the same time such mechanisms are the most apt to be rendered inoperative.

Therefore, it is the main object of my invention to simplify and improve damper regulating apparatus and produce a durable and inexpensive arrangement.

Another object is to provide an arrangement adapted to meet the requirement for successful commercial operation.

These and other objects are accomplished by providing damper regulating apparatus having a minimum number of simple cooperating parts including a timed actuating member for automatically changing draft conditions after the same has been properly set.

The invention is illustrated on the accompanying sheet of drawings in which Figure 1 is a side elevation of a furnace and my improved damper regulating means associated therewith;

Fig. 2 is an enlarged rear elevation of the alarm clock forming a part of my improved mechanism;

Fig. 3 is a sidel elevation of Ythe same clock, parts being broken away, showing simplified arrangement of parts foraccomf plishing the desired results; and Y Fig. 4 is a fragmentary sectional view of the same clock takenv .in the plane of line 4-4 of Fig. 3 showing the damper actuating spring. v

The various novel features of my Yinvention will be apparentfrom the following description and drawings, andwill be particularly pointed out in the appended claims;

My invention is illustrated in connection with a furnace 10 having the usual firing Specification of Letters Patent.

1915. serial No. 21,224.

door 11, hot air conveying pipes 12, smoke pipe 13 and ash door 14. The ash door is provided with the usual pivotally mounted draft'damper 15 and the bottom portion 16 of the smoke pipe has a common form of pivotally mounted check damper '17. To control the operation of these draft and check dampers in an efcient manner isa problem to which a great deal of attention has been directed. This particular type of control means finds effective application where the dampers are set by a manual operation at night and are automatically actuated in the morning at a desired time to cause a proper heating effect to prevail. All devices of this nature heretofore produced are relatively expensive, more or less cornplicated, having too many. parts, which readily get out of order, and are generally in. efficient and unsatisfactory.

My improved and simplified damper control means includes a clock 18 having an alarm mechanism 19 provided with a shaft 20, an actuating spring 21 therefor, and tripping mechanism 22. Removably secured to this shaft 20 is an auxiliary shaft or key member 39 formed integrally with which is a circular disk 23 having an opening 24 extending transversely therethrough, there being a flexible member 25 passed through said opening and adapted to be wound and un- Wound on said auxiliary shaft o-r key on opposite sides of saiddisk. It will be noted that the fiexible member 25 is vwo-und in different directions on opposite sides of said disk, the free end of one portion 26 ofthe Patented Mar. 4, 1919.

flexible member being connected to the draft y damper 15 and the free end of the other portion 27 being connected to the check damper 17. This latter portion 27 may be passedv through guide openings 28 in rafters 29 and over a' suitably supported pulley 30, the clock itself being suitably supported on a beam 31 between one of the rafters 29 and another member 32. To manually operate the shaft'39 and thereby the shaft 20, the former is provided with an integrally formedhandle 33, adjacent to which also is Y Yan integrally formed collar 34 to limit the width of Winding. of the flexible memberf25 in onedirection.

" `The Voperation of this 'damper control mechanism isV as follows: As shown in Fig. 1, the draft damper 15 is closed and the check damper 17 is opened, it being assumed that the furnaceA fire 26 of the flexible member being unwound tov a cer-tain extent from the key shaft 39- on one side of the disk 23, to' permit thedraft damper 15 to close of its oWn Weight. At the same time, the other portion 27 of the flexible member is Wound. a certain amount on said key shaft; 39 ony the other side of said disk 23;, Icausing the check damper 17 tojbe opened. Duringl this same operation the alarm or actuating spring 21 is Wound up to a desired degree to store an increased amount. yof energy therein.. The fire with this setting of the dampers is checked fol1 the night. As is Well knovvm under these conditions the temperature of thehouse decreases. To. cause anincrease in the temperature to a, comfortable degree by the usual time of arising.,I it isnecessary that the damper conditions be reversed. a feiv hours in advance thereof, such for example, as five oclock in the morning.. Such being the case, the alarm is set, as indicated in Figs. 1 and 2, to trip `at the desired hour.

lVhen this hour'in the morning is reached,

the tripping mechanism is actuatedY in the usual Way,I theshafts 20. and .39 thereby be` ing free to rotate in a clockwise direction; under the iniuence of the spring 21, causing,A portion 26 of flexible member to Wind up on-l the key shaft 39 on the first side of disk. 23f

to open-draft damper 15` and permitting portionv 27 of flexible member to unwind fromv said key shaft on the second side of said disk. under the, influence of the automatic closing movement of check damper 17., Under these, conditions, the draft damper 15 will be open and the check damper 17 closed to causey a more rapid combustion ofthe fuel to raise the temperature. 0f the house.V At night the,l dampers and clock may bei manually: set again preparatory to. an automatic reversing of damperconditions in the morning at a desired time.

This simple, compact and durablev arrangeT ment which is reliable and inexpensive, is. adapted to and does, meet, the requirements for which it is intended.

It is evident that modifications, of this arrangemcntV may be made,4 and it is my in-V tention to cover all;suchmodications. which.

do not involve a departure from the spirit and scope ofrmy invention as set forthin thel following claims..
