MANUFACTURE OF RIBBED PIPES.
SPECIFICATION forming part of Letters Patent No. 679,352, dated July 30, 1901. Application filed April 26, 1900- Serial No. 14,405. (No model.)
To all whom it may concern:
Be it known that I, WILLIAM B. WILLIAMS, a citizen of the United States,residing at Reading, in the county of Berks and State of Pennsylvania, have invented or discovered certain new and useful Improvements in the Manufacture of Ribbed Pipes, of which improvements the following is a specification.
The invention described herein relates to certain improvements in the method of manufacturing ribbed pipes, such as are described and shown in application, Serial No. 14,403, filed April 26, 1900.
The invention has for its object a method whereby a blank is formed having one or more ribs suitably arranged thereon, the bending of such blank to the form of a skelp, and then bending the blank to skelp form and welding the adjoining edges of the skelp.
The invention is hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a sectional view of a form of blank for the manufacture of single-ribbed pipes. Fig. 2 is a plan view of a bell or die constructed to bend the blank toskelp form. Fig. 3 is an end elevation of the same. Fig. 4 is a view in elevation of rolls constructed to weld the ribbed skelp. Fig. 5 is a sectional view of the blank having two suitably-spaced ribs. Fig. 6 is a sectional plan view of abell or die constructed to bend the two-ribbed blank to skelp form. Fig. 7 is an end elevation of the same. Fig. 8 is an inner elevation of one-half of the bending bell or die, and Fig. 9 is an elevation of a pair of welding-rolls.
I In the practice of my invention a blank 1 is formed by rolling or other suitable means of a width and thickness suitable for the size of pipe desired and provided with a rib 2, formed thereon in the rolling operation or in any other suitable manner, and preferably located in the middle of the blank and extending along the entire length thereof. This rib may be of any desired cross-sectional con-- tour suitable for the purpose to which the pipe is to be applied. The blank is heated in a suitable furnace and then drawn through the bending bell or die 3, which is constructed in the usual manner. As the bending-bell is made in two sections and arranged in such relation to each other as to form a slot 4 in the under side for the tongs, the rib 2 will pass along the slot without interfering with 5 As shown in Fig. 5, the blank 1 may be formed with two or more suitably-spaced ribs 2 of any desired cross sectional contour. These ribs should be so located as not to interfere with the bending of the blank to skelp 7o shape and the welding of the edges of the blank together-that is to say, the rib should be located at such a distance from the edges of the blank as to permit the welding of such edges together without the distortion of the ribs.
The bending or welding bell or die 3 is of the usual shape and construction, except that two spiral grooves 8 are formed in the inner walls of the bell-sections for the reception of the ribs 2". As the grooves are made of a width and depth greater than the width and height of the ribs 2 and the pitch or curvature of the grooves corresponds with the curvature of the inner or bending walls of the bell-sections, the ribs 2 will follow along the grooves with little or no friction.
The skelp is heated to a welding temperature and then passed through between rolls 9, having grooves 10, suitably proportioned to efiect a welding of the edges of the skelp. These rolls are provided with auxiliary grooves 11 for the reception of the ribs 2, and, if desired, these auxiliary grooves may be constructed to have a shaping action on 5 the ribs.
While it is preferred to form the ribbed pipes by bonding to skelp form and then welding between suitable rolls, it will be readily understood by those skilled in the art that the blank, especially if light in cross-section, may be bent and weld ed by drawing through a bell in the manner similar to that practiced in the ordinary method of manufacturing pipe. When using the bell or dies, the latter will be formed with grooves for the reception of the ribs upon the blank, so as to preserve such ribs from distortion during the welding operation.
I claim herein as my iuventiou As an improvement in the art of manufacturing ribbed pipes, the method herein described which consists in forming a blank with one or more ribs extending along one side of the blank, progressively bending such blank with the ribs outside, causing the ribs to follow and conform with the gradual curvature of the body of the blank and progressively Welding the edges of the skelp thus formed, substantially as set forth.
In testimony whereof I have hereunto set my hand.
