SINGLE-PIECE SHEETr META-L SPOUT.
SPECIFICATION forming part of Letters Patent NO. 622,222, dated April 4:, 1899 Application filed January 13, 1898. Renewed February 16, 189.9. Serial No. 705,694. (No model.)
To ctZZ whom. it may concern:
Be it known that I, JOHN W. GREENE, a citizen of the United States, residing at Waverly, in the county of Tioga and State of New York, have invented certain new and useful Improvements in Single-Piece Sheet- Metal Spouts; 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.
My invention has relation to an improvement in corrugated spouts for vessels, said spout consisting of a single piece of sheet metal having the corrugations in the end of the convexed side thereof at an intermediate section between the end of the spout and the lower point of j unction with the vessel,the said corrugations extending transversely across the under side of the spout and pitching the spout at the proper angle.
My present invention is an improvement over my prior patent, No. 530,597, issued December 11, 1894.
In the accompanying drawings, Figure 1 is a plan View of the blank from which the spout is made. Fig. 2 is a perspective view of the spout, showing the first step in the operation of forming the same. Fig. 3 is a perspective view of the spout, showing the second step in the operation of forming the same. Fig. 4 is a perspective view showing the completed spout. Fig. 5 is a sectional view out on the line 5 5 of Fig. 4. Fig. 6 is a sectional View of the spout cut on the line 6 6 of Fig. 4; and Fig. 7 is a sectional View of the spout'cuton the line 7 7 of Fig. 4.
The blank is cut as outlined in Fig. 1. The lower portion of the blank is provided with the side flanges 1 1, and the upper portion of the blank is provided with the side flanges 2 2, the flanges 1 1 being formed upon the lines 3 3, and the flanges 2 2 being formed upon the lines 4 4. The flanges 2 2 are locked together at their edges, forming a seam 5, (see Figs. 2 and 3,) the said seam extending the entire length of the upper side of the spout. The flanges 1 1 are provided with the locking edges 6 6, the said edges 6 6 being adapted to lock with similar locking edges of the body is rounded along its longitudinal axis.
of the Vessel, as indicated in Fig. 7 The said Thus the spoutis secured to the body of the,
vessel. The under side of the spout proper is provided at an intermediate section with a series of corrugations 7, the said corrugations extending transversely across the end of the convexed side of the spout, thus pitching the spout at the proper curve or angle and adding greatly to its strength.
The following is a process by which the spoutis formed up. The locking edges of the flange 2 2 are first turned up, and the said flanges 2 -2 are then bent upon the lines 4 4, and the blank being flat the said flanges 2 2 extend up at ring angles to the same. The blank is then put into a forming-machine and This brings the locking edges of the flanges 2 2 together,and they are secured together,forming' the seam 5, the blank then being in the shape as shown in Fig. 2. The blank thus formed is then placed in a press and the corrugations,
as shown in Fig. 3, are formed on the under side of the spout. At the same time the flanges 1 1 are turned out, and the locking edges 6 6 are bent up at the edges of the flanges 1 l. The spout as thus formed is then put in a press with a proper-shaped die, the lower portion of the spout being firmly secured, the spout proper, together with the corrugations, as shown in Fig. 3,being substantially straight. A tool is then placed over the upper small end of the spout, and the spoutis given the proper angle or curve by slightly bowing the corrugations.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In a single-piece sheet-metal spout, the spout proper having a convexed portion forming its under side, the edges of the sheet forming an unbroken interlocking seam in the upper side of the spout, a number of alternately-arranged ridges and furrows extending transversely across the under convexed portion of the spout, the ends of said ridges one side of the flanges and the other edge exand furrows terminating at the edges of the tending 0n the opposite side of the flanges.
