NOISELESS STEAM WATER-HEATER.
Specification of Letters Patent.
l-atenteo. may 29, 1906.
To all whom, it may concern."
Beit known that I, JoH GEoRGE IIUF-' NAGEL, a citizen of the United States, residing at Scranton, in the county of ,Lackawanna and State of Pennsylvania, have,invented certain new and useful Improvements in Noiseless Steam Water-Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to improvements in mufflers, and particularly to steam waterheaters.
The object of the invention is the provision of means for facilitating the mufiling or discharging of steam from an outlet WlllCll may.
be positioned within a tank or receptacle containin a'liquid. 4 I
Wit this and other objects in view the invention consists of certaln other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described,
illustrated in the accompanying 'drawin s,
and more particularly pointed out in t e claims hereto appended.
In the drawings, Figure 1 is a view in side I elevation of a device constructed in accordance with the present invention. Fig. 2 is a vertical longitudinal sectional view of the device depicted in Fig. 1, and Fig.3 is a transverse sectional view of the same.
Referring'to the drawings by numerals, 1
designates a cylindrical primarycasing which is provided with transverse apertures 2. At each end of the casing there is formed an annular inte al extension 3.
An auifiary cylinder 4 is positioned upon the parallel cylinder 1 between the annular extensions Eor ends 3- 3. This cylinder 4 is formed of a wire mesh or screen. Between the primary and auxiliary cylinders 1 and 4,
respectively, a compartment 5 is formed;-
Within this compartment there is positioned porous or fibrous filling means as, for mstance, hem which insures of the noiseless discharge 0 the steam from the apertures 2' of the primary cylinder 1.
The auxiliary wire-mesh or screen cylinder 4; is positloned between and lies flush with the outer surface of the annular extensions or ends 3 3 of the primary cylinder.
Integral with one of the ends 3 is a thread ed tubular portion 6. The conducting means for the steamas, for instance, a hose or pipeis connected to the muffler by means of this tubular ortion 6. It is to be noted that the bore 0 the tubular portion 6 is of the same diameter as the bore of the primary apertured cylinder 1. By reason of this the steam is not retarded in its passage into the muffler. The passage of the steam from the interior of the primary cylinder to the outer atmosphere is retarded bytwo meansto wit, a cylindrical hemp jacket and a wire-,mesh cylinderQ Although I referably use hemp for forming the cylindrlcal fillin' jacket, in some instances other fibrous fil ing means may be employed.
My improved muffler is particularly adapted to be secured to the discharge end of ahose or tubing which is positioned within a tank or receptacle containing liquid which is to be heated. The discharge of the steam through the three cylinders or casings constituting my muffler is comparatively noiseless.
What I claim is Y 1; A device of the character described, comprising a primary cylinder, formed with rows of sta gered radiating apertures therein, enlarge ends formed ntegral with said cylinder, an auxiliary wire-mesh cylinder secured to said primary cylinder and lying flush with the outer surface thereof, and a cylinder of fibrous material interposed between said primary and auxiliary cylinders.
2 A device of the character described, comprising a cylinder, formed with staggered apertures therein, closed at one end, a tubular threaded portion upon its opposite end, a
Wire-mesh cylinder positioned between the ends of said primary cylinder, and a hemp filling positioned between said primary and auxihary cylinder.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN GEORGE HUFNAGEL.
