METHOD OF MAKING TU'NNEL-SEGMENTS.
Specification of Letters Patent.
Patented July '7, 1908.
Application filed April 26, 1906. Serial No. 313,837.
To all whom it "may concern:
Be it known that I FRANK F. VANDEvonT, a citizen of the United States of America, residing in Germantown, in the county of Philadelphia, in the State of Pennsylvania, have invented a new and Improved Method of Making Tunnel-Segments, of which the following is a specification.
My invention consists of an improved method of making wrought iron or steel segments for lining tubular tunnels, which form the subject of Letters Patent No. 806,673, granted to Henry Japp, December 5th, 1905.
The object of my invention is to make such segments by an economical and eilicient method.
In the accompanying drawings Figure 1 is a sectional perspective view showing the first step in my process; Fig. 2 is a view of a pass in the rolls, showing another step in the process; Fig. 3 is a perspective view of the blank at a succeeding stage; Fig. i is a view of the forged and welded segment, finished; except -for the punching ol the bolt holes; Fig. 5 is a perspective view of a modification; and Fig. 6 is a view of an additional operation which may be employed and Fig. 7 is a view of another modification.
In carrying out my invention, I first roll a channel of about the section illustrated in Fig. 1, and of a width equal to either the length or breadth of the desired segment.
A The channel may be rolled of suilicient length to out two or three or more segment blanks -from it. I prefer to roll the channel with edge grooves on the flanges (Fig. l), for the usual calking strips along the llanges oi the segments.
I prefer to roll the channel of such size that its width shall constitute the width or length of the segment measured circumierentially of the tunnel when the finished segments are in place. Accordingly, after the channel has been rolled to the form shown in Fig. 1, and while still hot, it may receive one or more passes through rolls to curve it, as indicated for example in Fig. 2, which shows a form of pass adaptable for this curving action. Or this curving may be obtained by a pressing operation. Or where it is not necessary to curve the segment, a Hat form as shown in Fig. 5 being sullicient, this curving step may be omitted. The next step in the operation is to cut the curved channel to the proper length and by saws or otherwise to cut oil sui'licient oi the ends oi" the side flanges a oi the section to leave aprons I) at opposite ends of the section, as shown in Fig}; Then these aprons l) are bent up towards, and their edges welded to, the ends of the side flanges a, to Form end flanges, and so producing the four-sided flanged and curved or llat segment shown in Fig. 4 or Fig. 5, ready to have the bolt holes punched or otherwise formed in the ilanges. Grooves 1/ may also be formed in the edges of the end flanges l) for the calking strips.
To accomplish or aid in the welding, and to strengthen the joint, an angle piece 1) (Fig. 6) may be applied in the corner, so that when grasped between the dies 0 and (Z of an electric welding press, the joint will be electrically welded. Or in some cases the apron may be of such width as to permit of the introduction, of a square bar or fillet at the outer angle, as seen in Fig. 7.
\Vhile I prefer the order of operations described, I do not wish to limit myself thereto. For example, the curving of the segment may succeed, instead oi precede, the cutting, and may be produced by other means than rolling.
By the described method of operation, I am enabled to produce economically wrought iron or steel Hanged tunnel segments with sharp corners, calculated to successfully stand the strain, stresses, and pressures to which tunnel segments may be subjected in use.
I claim as my invention.
1. The mode herein described of producing wrought iron or steel tunnel segments, said mode consisting in forming a wrought channel, cutting it to length, removing the I ends of the flanges and bending up the aprons thus produced to form end flanges and Welding them to the end of the side flanges.
2. The mode herein described of produc ing Wrought iron or steel tunnel segments,
said mode consisting in producing a blank with side flanges and end aprons, bending up these end aprons and Welding them to 1-) to the ends of the side flanges.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses.
FRANK F. VANDEVORT.
