IMPROVEIVIIEINTv IN HOT-BLAST PRESSURE-GAUGES.
The Schedule referred to in these Letters Patent and making part of the same.
To all 'whom it may concern:
Be .it known ,that I, J ons Sronnn, of the Y city, county,and State of New York, have invented anew and improved Hot-Blast Pressure-Gauge; andl do hereby declare the following -to be al full, clear, and exact description thereof, which will enable those skilledv in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing- Figure l represents a longitudinal central section of this invention. t
Figure 2 is a side elevation of the saine.
vSimilar letters indicate corresponding parts.
'.lhis invention consists in the axrangcnicntof apro teeting-tubc, in combination with the spring, which is attached to the piston of the gauge, said protectingtube heilig situated in the interior of the channel, through which the hot-blast passes to the piston, in such a manner that the lspringl is protected against the influence of the hot-blast, and said hot-blast is enabled to act on the piston without disturbing the correct action of the gauge.
A tapering nozzle, secured to the casing of luy gauge, serves to applythe same conveniently to the tuyerepipe of a ,blast-ihrnace.
In the drawing- The letter A designates a tubular case, which is bored out to receirje the piston B.
This piston connects, by a rod, C, with a secondary piston,l D, that serves to steady the. Inain piston B, and also forins the bearing for the index a, which projects through a slot, b, in the case A, and traverses over a scale, c, marked on said ease, as shown particularly in iig. 2 ofthe drawing.
lhe piston 1S is subjected to the action of a spring, ll, which is fastened, at one end, to a cross, c, and at its other end to the piston, so that by the action of said spring the piston is pulled down, causing the index c to point to the zero-line ofthe scale c.
The cross e is secured in the bottom 'end of the case A, and it supports a tube, f, which surrounds the of its spring al, and the index shows the aniount'of spring d, and protects the saine against the action of the hot-blast. A
In practice, I propose to attach au 'additional protecting-pipe, g, to the bottom end of the piston B, said lpipe being intended to surround the spring,and to fit into the tube f, as indicated in red outlines in'tig. 2.
By the application of this second protecting-pipe, the hot-blast will be prevented from coming in contact with any portion of the spring, even it' said spring is stretched out.
'lo the bottom end of the case A is secured a tapering nozzle, E, capable ot' being inserted into the tuyere- Y l pipe of a blast-tinnace, and in the outer end of said case is fasteneda handle, F, of wood or other bad conductor of heat, so that the gauge can be conveniently handled without burning the fingers.
If it is desired to ascertain the pressure of the air or blast in a blast-furnace, the gauge is inserted, by means of its tapering ynozzle,.nto one of the tuyercpipes, thus exposing the pistonB to the action of lthe hot-blast.
lhe piston is thereby forced out against the action t pressure ot' the hot-blast.
During this operation the spring is protected against-wl the injurious influence of the hot-blast by the tube f, and the correct action of the instrument is insured.
Having thus described my invention,
What I claiin as new, and desire to secure by Letters Patent, is-
1. .lhe protecting-tubes fg, fitting and sliding wit-hin cach other, in combination with the case A, piston B, cross e, and spring d, substantially as and for the purpose described.
2. In combination therewith, the secondary piston D, elevated above piston B, guiding the latter, and carrying the index u, as set fort-h', for the purposedescribed.
