IMPROVEMENTIN MACHINES FOR BENDING TUBE-SKELPS.
Specification forming part of Letters Patent No. 154,083, dated August 11, 1874; application filedl July 17, 1874.
To all whom it may concern:
Be it known that I, J oNAs RAvENsonoFr, of Gohoes, in the county of Albany and State of New York, have invented a certain new and useful Improvement in Machines for Making Unwelded Pipes, of which-the following is a specification:
This invention is illustrated in the accompanying drawing, in which- Figure 1 represents a plan or top view. Fig. 2 is a front view of the same. Fig. 3 is a transverse section of the same in the plane :0 as, Fig. 1. Fig. 4. is a similar section in the plane 3/ y, Fig. 1. Fig. 5 is a detached section of the finished pipe.
Similar letters indicate corresponding parts.
This invention relates to improvements in machines for forming unwelded pipes'by passing the blanks first through crimping-rollers and then through finishing-rollers. The invention consists in combining with the crimping-rollers guide'rollers, to keep the blanks in the proper direction, and arranging between the crimping-rolls and the finishing-rolls a tapering box containing suitable rollers, whereby the edges of the blanks, after the same leave the crimping-rolls, are gradually turned in and guided into the cavities of the finishingrolls.
In the drawing, the letters A B designate two crimping-rolls, one of which is provided with a groove, a, of semicircular cross-section to receive a bead, b, of corresponding shape formed on the other roll. With these two rollers are combined guide-rollers G, which are set in oblique positions, converging toward each other at the top, and which serve to carry the blanks to the crimping-rolls and to keep them in the proper direction. The blanks are rolled out in the usual manner, and they pass immediately (without being reheated) in between the crimping-rollers, which impart to each blank the shape of a semicircular trough. On leaving the crimping-rolls, this semicircular trough passes through the compressionbox F to the finishing-rolls D E. The sides of said compression-box converge from the crimping-rolls toward the finishing-rolls, and they form the bearings for rollers r s, which assist in turning up the edges of the semicirlar trough, so that the same, on reaching the finishing-rolls, will be in a condition to enter the grooves d e in the same.
If desired, the sides of the compression-box may be provided with anti-friction rollers, so as to reduce the friction between the same and the edge of the blank.
The roll D is provided with a groove, d, and the roll E with a deep cavity, 0, from the bottom of which rises a circular rib, f. By the action of these two rolls the blanks are closed up, to the form shown in Fig. 5. The crimping-rolls A B are geared together by pinions g, and the finishing-rolls D E by pinions h, and they receive motion from a cog-wheel, i, Fig. 1, which is mounted on an intermediate shaft, j, to which motion is imparted from the driving-shaft k, by means of a pinion, l, and cog-wheel m.
By these means a simple and compact machine is produced, by which unwelded pipes can be manufactured with great dispatch.
What I claim as new, and desire to secure by Letters Patent, is-- In a machine for making unwelded pipes, the combination of the obliquelyarranged guide-rollers C O with the crimping-rollers A B, the tapering compression-box F, provided with the rollers r s, and the finishing-rollers D E, the whole being constructed and arranged for operation as herein shown and described.
In testimony that I claim the foregoing I have hereunto set my hand and seal.
JONAS RAVENSGROFT.
