PATENT OFFICE BENJAMNV. onor,l or cUNoT, INDIANA.
SELFTBEGULATING pararse.
Specication of LettersPatent.
Patented April 7, 1908;/
Application led January 11, 1907. Serial No. 351,824.
'To all whom it may concer-n:
Be it known that I, BENJAMIN V. Cnor, a citizen of Ithe United States7 residing at Cunot, in the countyof Owen and State of Indiana, have invented certain new and useful Improvements in Self-R egulating Dam- Which the following is a specification.
pers, o .4 Myinvention relates vto 4dampers of the self-regulating type and has for its object the provision of'an instantaneously removable and replaceable damper comprising a cone- I ,shaped diaphragm suspended in the pi e by y'means of hooks secure to the upper ef ge of a vertical section of pipe, .and a cone-sha ed cut-off suspended on one arm of a lever ulcrumed on the edge of a hole or slot in the pipe and extending out .of the pi e and have a counter Weight adj usta ly securedthereto,
4 The construction and advantages of my invention Willl be described in detail hereinafter 4and illustrated in t-he accompanying drawings lin Which- Y Figure 1 is a longitudinal sectional view 'of a fragment of a length of stove pi e showingv my improved damper-in position t erein an in seotlon, Fig. 2, a detail'vie'w in elevation of the cone-sha ed diaphragm, and Fig. 3, a detail view in e evation of the damper.
In the drawings similar reference charac'.- ters indicate corresponding parts through- Out the several views. Aindicates a length of stove i e. f lB indicates a conical-sha e diaphragm suspended from the upper e ge of length A by means'of hooks C riveted or otherwise secured thereto and having an opening D in its ulpper end and other openings E in ,its 1nc ined surface for the passage of smoke and gases. y
F indicates la cylindrical apron or flange.
I extending downwardly from the llower edge.
of thel cone-shaped portion Which serves to cause a closer lit between the diaphragm and v the pipe. l G indicates .the dam er which is conesha ed so as to t snug v the lower surface `of t e diaphra in -B and is longenough to entirely cover t e holes or openin s E therein, when in engagement with the iaphragm,
butdoes not extend t-o--thefull diameter of the pipe so as to leave a space for the passage of smoke around its edge when not in cngage ment with the diaphragm. A
H indicates a hole in the upper endof the damper and I a wire bail secured in the damper across said hole.
J indicates a lever fulcrumed in a hole or Slot K in ipe A the lever being provided with an o set L to seat on the edge of said hole or slot. of the pipe A is bent to Jform an eye M, and N indicates a rod securedin said eye M and to Wire bail I to support the damper G.
0 indicates a Weight adjustably secured to the arm of the lever outside of the pipe A by means of set screw P.
In operation when the amount of heat passing through the pipe A is normal the damper G is in the position shown in F ig. 1 but as the heat increases, causing an increase in the draft, the damper G is raised thereby gradually cutting-off the area of egress of the products of combustion which continuing lwould eventually cut-off the' draft exce t through the' hole H. Then as the heat i* -minishes the pressure against the damper'G decreases and permits it to recede from the diaphragm and the operation is repeated. I have stated that the damper Would be raised so high as to cut-off egress of the prod-v ucts-of combustion except through hole H but when in satisfactory operation the damper will reciprocate but slightly so as to keep the iire at substantially a uniform condition. ItWill be also understood that the The arm of said lever J inside y temperature of the fire mav be regulated by adjustingv the weight O onlever J and if desired that the arm of the lever may be providedjvith a graduate-d scale to assist in posi- -tioning the Weight to secure the temperature desired It will also be understood that as the diav phragm B and its connectionsare readilyr removable from t-he length of stove ipe A the damper may be readily transferredpfroin one stove pipe to another.
Having thus described my invention what Iclaim is*d I In a damper', in combination'with a stove pipe, acone-shaped and perforated diaphragm contained in the pipe, 'said diaphragm being provi-ded with a eentm1openng,a1everfu1 theren, substantially as shown dnd de l crumed on the pipe, and a cone shaped hol E scribed. 10
