UNITE JOHN KROPACZ, 0F ROSEDALE, ALBERTA, CANADA.
STEAM-WHISTLE DIAPHRAGM.
Specification of Letters Patent.
Patented July 29, 1919.
Application filed November 2, 1918. Serial No. 260,822.
' To all whom it may concern:
Be it known that I, JOHN KROPACZ, a subject of the Emperor of Austria, residing at Rosedale, Province of Alberta, and Dominion of Canada, have invented certain new and useful Improvements in Steam-Whistle Diaphragms, of which the following is a specification.
This invention relates to improvements in the connections between a steam boiler and whistle, and has as its special object the provision of means whereby water is prevented from entering the whistle so as to clog the same.
A further object is to provide. means whereby the whistle is prevented from operating except under a pressure of steam above the normal. These objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a material part of this disclosure, and in which- Figure 1 is a perspective view showing a conventional type of locomotive boiler and furnace, and indicating the application of the invention.
Fig. 2 is an enlarged fragmentary vertical sectional view taken through the diaphram through which steam passes to the whistle, and
Fig. 3 is a transverse sectional view taken on line 33 of Fig. 2.
In the drawings, the furnace is represented by the numeral 10 and formed therewith is a boiler 11, its rear end resting upon a pedestal or support 12, the furnace doors 14 are arranged for stoking purposes, Wlllle the boiler tubes are accessible through the doors 15, the furnace is provided with a smoke stack 15 and the boiler with steam domes 16 and 17, as usual.
'Steam is taken from the boiler 11 through the pipe 18 and conducted lay the pipe 19 to wherever it may be require a. T fitting 20 is fixed upon the pipe 18, closely adjacent to the boiler, from which is a riser 21, having fixed therein a control valve 22, leading to the whistle 23, which, like the other parts, are of the usual form of construction.
Set in the pipe 21, above the valve 22, is a chamber 25, having reversed conical walls 26, from which extend base flanges 27 secured together by bolts 28, connecting the two portions of the pipe in a rigid manner, and engaged between the flanges 27 is a diaphragm 30 formed with marginal openings 31, through whichthe bolts 28 pass. Formed in the diaphragm are a plurality of minute perforations 32 adapted to admit the passage of steam when under a high pressure, but calculated to prevent a low pressure of steam, or water from passing through to the whistle 23.
In operation, when steam is raised in the boiler, and the valve 22 is in an open position, should an excessive or undesirable pressure arise therein, it will pass through the minute perforations 32 to the whistle, causing it to give an alarm, but under ordinary circumstances a low pressure of steam is unable to'pass through the perforations and the whistle therefore remains silent.
Having thus described my invention what I claim asnew, and desire to secure by Letters Patent, is
In a device of the class described, including a chamber having reversed conical walls, flanges connecting the faces of said conical walls rigidly together, a diaphragm disposed between said flanges, and a plurality of mi nute perforations in said diaphragm, said perforations being adapted to retard the passage of steam when at a low pressure and permit a high pressure steam to pass through.
In testimony whereof I have affixed my signature.
JOHN KROPACZ.
