HEATING DRUM OR PIPE.
SPECIFICATION forming part of Letters Patent No. 393,313, dated November 20, 1888.
Application filed February 2, 1888. Serial No. 262,699.
To all whom it may concern:
Beit known that I, JOHN ROMANG, of Milwaukee, in the county of Milwaukee, and in the State of Visconsiu, have invented certain new and useful Improvements in Heating Drums or Pipes; and I do hereby declare that the following is a full, clear, and exact description thereof.
Myinvention relates to stove-pipes or heating-drums, and will be fully described hereinal'ter.
In the drawings, Figure I is a section on line l l, Fig. 2. Fig. 2 is a vertical central section. Fig. 3 is a section on line 3 3, Fig. 4, and Fig. Li is an elevation, partly in section.
A is the pipe or drum, which is formed with chambers B I3, that open into each other.
C is a frame that is suspended in the pipe by a pin, c., that passes between the folds b of a metallic lever, D, and through the sides of the frame C and pipe A. rIhis pin has a thumb-piece, c, on one end, and is locked to the lever D by a small key, d, that is passed through a perforation, c, in the piu c and lever D.
E are the dampers, of which I may use any number, and these are loosely hung between the sides ol' the frame on pins j', while their edges on one side are pivoted to a strap, H, by pins 7L, a like pin connecting the upper end ol' the strap to the outer end ofthe arm of leverl). The damper-s are of a diameter slightl y less than that of the pipe between the chambers, and when in place are suspended each in the center ol' one ol' the chambers B, so that when closed in the position shown in Fig. 2 they do not cut off the drai't, but merely deflect the heat against the sides ofthe chambers. rIhe opening and closing` is accomplished by turning the pi n a., which, acting on lever H, causes it to turn the dampers together.
When vit is desired to get all the radiation (No model.)
possible from my improved drum, the dampers are set as shown in the drawings, and from this the radiation can be diminished by tipping the dampers until they stand in a vertical position. When the drum is to be cleaned, the frame O may be entirely withdrawn. I do not propose to confine myself to the exact shape of my drum or pipe in crossor vertical section, as this maybe varied without departing from the spirit of my invention.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. rIhe combination, with a heating-drum or stove-pipe, of a pin passed through the sides of said drum or pipe and provided at one end with a thu nib-piece, a frame suspended from the pin, a lever keyed to said pin between the sides of the frame, a strap pivot-ally connected to the lever, and one or a series of dampers journaled in said sides of the frame and pivotally connected to the strap, substantially as set forth.
2. The combination, with aheating-druin or stove-pipe, of the frame O, the pin a, passed through the sides ofthe drum or pipe and the sides of said frame, the lever D, provided with folds b, that encircle said pin, the key d, passed through the pin and lever, the strap H, pivotally connected to the outer end of said lever, and the dampers E, journaled to the suspended frame and pivotally connected to said strap, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and Slate of XViscousin, in the presence of two witnesses.
