NOZZLE FOR BLUING STEEL SHEETS.
Specification of Letters Patent.
Patented ma 6, 1909.
Application filed August 28, 1908. Serial No. 460,618.
To all whom it may concern:
Be it known that I, JoHN E. OARnAHAN, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, haveinveuted a new and useful Nozzle for 'Bluing Steel Sheets, of which the following is a specification.
A well-known process for bluing steel sheets consists in heating a ack of sheets suitably inclosedto exclude t e air and the gases'of combustion, and then uncovering the pack and impinging the side edges 0 the sheets with a stream of steam, which serves the'double separating the u 0t 1 per sheets one from aner, so that t ey can be conveniently grasped and removed by ordinary tongs,
and of oxidizingb the surfaces of the sheet by reason of the ath which is given to both sides thereof. In the performance of this rocess, the best results are usuall obtained y impinging the edges of the eets with live steam and the steam is preferably applied by discharging it from the flattened mouth of a nozzle so as to impinge the sheets with a wide but thin sheet of steam. A difiicultyis experienced in the use of live steam for the reason that when the sheets are impinged by the unreduced force of the ferred to herein,
steam, the face or surface of thesheets are cut or abraded to such an extent as to prevent the formation of an oxidizedcoating thereon or to remove the same after it has been formed and if it is sought to remedy this difliculty by reducing the pressure of the steam inthe su ply pipe at a point remote from the nozz e, the steam in the reduced current loses its lifebefore it is discharged from the nozzle and reaches the sheets and thus loses its best qualities as an oxidizing agent. This difliculty is overcome by enlarging the body of the nozzle as compared with the cross section of the suipply pipe so as to form a pressure reducin rum or chamber in the nozzle adjacent to its discharge a rture, which aperture is preferably ma e in the form of an elongated slot in the forward end of the nozzle.
The pertinent features of the process reto which the invention relates, are illustrated in the accom anying drawings, forming part hereof, in w 'ch- Figure 1 is a perspective view showing a purpose of loosening and thereby servin and the improved nozzle,
pack of sheets uncovered and an adjacent steam pipe and nozzle, showing the method of impinging the sheets with the stream of steam; Fig. 2, a perspective view of a preferred form of nozzle and a short section of the supply pipe, with parts broken away to show details of the connecting collar; and Fig. 3, a perspective View showing a modified form of the nozzle.
Similar numerals refer to similar parts throughout the-drawings.
The nozzle 1 is preferably formed from a section of pipe havin a diameter some two or three tlmes the diameter of th e s upply pipe 2, and having theforward end flattened and swaged to make the outlet aperture in the form of the elongated slot 3. The rear end of thenozzle and the forward end of the supply pipe are preferably threaded and connected to ether by the ordinary reducing collar 4. he su 1y pipe is preferably provided with a flexi i e joint as 5 which permits the nozzle to be oscillated, laterally at least,
to impinge the side edges of the sheets throughout their entire length.
The modified form of thenozzle illustrate ed in Fig. 3 is formed of a section 1 of pipe havin a diameter considerably larger than the diameter of the supply p1pe 2 to the end of which supply pipe the nozzle ipe is transversely connected. Each end 0 the nozzle ipe is closed by a cap 6 and the forwar side of the same is provided with the longitudinal slot 3, the edges of which slot are preferably bent outward to form the forwardly flaring lips 7. p
It is evident that in eitherform of the nozzle herein illustrated and described, there is formed a chamber or drum in the body of the nozzle and adjacent to the outlet aperture thereof, which chamber is considera ly larger in diameter and the outlet aperture is preferably somewhat larger. in area than the cross section of thesupply pipe,
live steam an to soften the force of the dischar thereof against the edgesof the sheets, at without In any manner impairing the life of the steam or reducing its oxidizing qualities. And it. will be understood that the form of nozzle herein set 'forth can be employed to discharge water and various aqueous and other vapors from a relatively smaller supply pipe.
to reduce the pressure of the What I claim as my invention, and desire to secure by Letters Patent, is-
1. A nozzle for bluing steel sheets having a supply pipe inlet in' one end and an elonh gated discharge slot in the other end having a greater area than the inlet, and an enlarged chamber in the nozzle adjacent to the discharge slot.
2. A nozzle for bluing steel sheets having a supply pipe inlet in one end and a dis- 10 charge aperture in the other end having a greater area than the inlet, and an enlarged chamber in the nozzle adjacent to the discharge aperture.
