J. M. HOPWOOD. FLUID PRESSURE NOZZLE,
APPUEATION HLED MAR-8,19IL
Patented Aug. 28, 1917.
FIEJ- INVENTOR ml M. HOPWOOD, OF PITTSBURGH, PENNSYLVANIA.
FLUID-PRESSURE NOZZLE.
Specificationof Letters Patent.
Patented Aug. 28, Milt.
Application filed March 8, 1917. Serial No. 158,522.
To all whom it may concern:
Be it known that I, JOHN M. Horwooo, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improvements in Fluid-Pressure Nozzles, of which improvement the following isa specification.
As is well known in the art, the internal shape, contour and dimensions of nozzles for air and steam blasts are carefully determined and must be maintained in order to insure the greatest efficiency, as the slightest variation in dimensions and shape of the interior of the nozzle will result in ineiiicient action.
On account of the inaccessibility of the nozzle in most cases, and the fact that careful measurement or calipering will be necessary to determine where and when inaccuracies occur, such nozzles are frequently used for a long time after they have become ineficient.
The object of the invention described herein is to provide means whereby an indication will be given in caseof the wearing away and consequent enlargement of the most important portion of the nozzle. The invention is hereinafter more fully described and claimed. 1
In the accompanying drawing forming a part of this specification, Figure 1 is a lon- 'tudinalsectional view of a nozzle having its discharge end arranged within a directing pipe, such as is used for example in the removal of ashes, etc.; Fig. 2 is a transverse section on a plane indicated by the line 11-11 Fig. 1.
In the practice of the invention, the nozzle is constructed as regards its internal shape and dimensions in the usual or any suitable manner, and may have its discharge end supported or secured in a directing pipe 2. In the form of nozzle shown, the part which will most rapidly wear away, is at the narrowest part of the throat, as at a, and in order to give an indication of an in urious wear, a series of holes 3 are bored radially from the exterlor of the nozzle into proximity of the inner surface of the throat.
The proximity of the ends of these radial holes to the inner surface will be determined by the amount of wear permissible before renewal is necessary or desirable. In the mner wall of the supported member 2, and in line transverse of the portion occupied by the radial holes in the nozzle when screwed into position, is formed a groove 4 with which is connected a suitable alarm or indicator as the whistle 5. As soon as any portion of the wall is so worn or cut away, as to establish communication between the bore of the nozzle and the radial holes, the stream of fluid will flow into the groove and pass into and operate the whistle, or the flow of fluid through the nozzle will cause a flow of air inwardly. Whether the flow through these radial holes is outward or inward, of course depends upon the positions of the holes relative to the throat of the nozzle and the angle of the axes of the holes to the axis of the nozzle.
It will be understood that any form of signaling or indicating device adapted to be operated by the flow of fluid through the radial holes, may be employed in lieu of the whistle.
I claim herein as my invention:
1. A nozzle for air or steam blasts having its walls reduced in thickness at points liable to wear, and an indicator adapted to be operated by fluid under pressure escaping through an opening formed by the wearing away of such reduced wall.
2. A nozzle for air or steam blasts having a plurality of radial holes extending into points closely adjacent'to the inner surface of the nozzle, and an indicator adapted to be operated by fluid escaping through one or more of said radial holes.
In testimony whereof, I have hereunto set my hand.
JOHN M. HOPWOOD.
