VVILHELM BOEOKER, OF SOHALKE, PRUSSIA, GERMANY.
MACHINE FOR FINISHING RAILROAD-SPIKES.
SPECIFICATION forming part of Letters Patent No. 424,167, dated March 25, 1890.
Application filed April 26, 1889. Serial No. 308,692. (No model.)
To all whom it may concern- Be it known that I, WILHELM BOECKER, a subject of the King of Prussia, residing at Schalke, in the Kingdom of Prussia, German Empire, have invented new and useful 1m,- provements in Spike-lI/lachines, of which the following isa specification.
My invention relates to improvements in spike-machines; and it consists in the particular construction and arrangement of parts, as hereinafter described, and pointed out in the claim.
Figure 1 illustrates in plan view and side elevation a spike constructed in accordance with my invention. Figs. 2, 4, 5, 6, and 8 are plan views, and Figs. 3 and 7 vertical transverse sectional views, of bars from which the spike-blanks are cut. Fig. 9 is a vertical sectional elevation, and Fig. 10 a side elevation,
of a machine for working and finishing the spike-blanks constructed in accordance with my invention. Fig. 11 is an enlarged plan view, and Fig. 12 is a vertical transverse sectional view, of the lower portion of the machine illustrated in Figs. 9 and 10, showing the disk for carrying the matrices. Fig.13 is a detail plan view of a portion of the disk, showing a matrix in position therein; and Fig. 14 is a transverse section taken on the line a b in Fig. 12.
Hook-nails such as are shown in Fig. 1 of the accompanying drawings, or of similar construction, and employed for fastening rails, have been made hitherto generally by hand labor. According to the hereinafter-described method, in combination with the machine shown in the drawings and described in this specification, it is possible to obtain a perfect and well-made hook nail or spike almost entirely Without any hand labor.
The improved hook-nails are made from bars of iron, or of any other suitable material, which are formed into the shape shown in Figs. 2 and 3 by rolling, pressing, hammering, or by any other suitable means. As will be seen from the drawings, the bars employed for manufacturing the spikes are furnished with bosses at the places where the heads of the spikes are to be formed,
For producing the blanks, the bar shown in Figs. 2 and 3 is divided on the lines marked in Fig. 4E. The division may be effected by sawing, stamping, cutting, slitting, or by any other suitable operation, and the blanks W W are thus obtained. It is advantageous to divide a bar stretched by stamping, (see Fig. 5,) on the dotted lines shown in Fig. 5, in
such manner that at each pressure exerted whereby two'other blanks are cut off. Figs.
6 and 7 show a bar having bosses at both sides. The blanks for making spikes are cut out from the rod in the same manner as above described.
hereinafter-described machine may be used for this purpose. The blanks are first heated in a furnace to a red heat, and are then separately introduced into one of the matrices C O .0 C of the machine (see Figs. 10 and 11) in such a manner that the boss of the blank enters the enlarged part of the matrix and its point strikes against the bottom of the same. A certain number of matrices are arranged in tapering sockets B in a disk B, which is rotated by any suitable means-as, for instance, that shown and hereinafter described-so that the matrices will be consecutively brought underneath the die and be stopped there until, by the pressure exerted by the die, the finished nail is formed in the matrix. Motion maybe imparted to the disk by the toothed wheels Z Z and by means of the machine shown in Figs. 9 and 10 of the accompanying drawings. By means of the eccentric E, (see Figs. 9 and 1 0,) connectingrod S, lever H, pawl K, and ratchet-wheel R, the disk B, containing the matrices C O 0 C is turned a quarter of a revolution, so that matrix C, which has just been filled, is brought exactly underneath the die D, (Figs. 9 and 10,) the disk B and the matrices being fixed in position by a spring-bolt F, catching into a corresponding recess of the disk. An-
Fig. 8 represents the rod after the blanks W W W W have been cut out. The said blanks may now be worked and finilShGd so as to form spikes by hand, or the other eccentric J presses the die D into the conically-shaped aperture (1 of the matrix held fast by the spring-bolt, whereby not only is the head forced into the matrix, but also the point, which, in consequence of the oblique cutting, stands laterally, is pressed exactly in the middle line of the blank, as shown in Fig. 12. 011 the further revolution of the disk B the matrix C is pushed out by the pressure of the partially or entirely eccentrically-arran ged fixed disk L, whereby the matrix, which is composed of four sliding parts e, will, in consequence of its conical side surfaces, be opened out somewhat, so that when it reaches its lowest position at C it will let fall the finished spike. The center of the fixed camdisk L is at 00. (See Fig. 11.) The construction of the disk B, movable upon the fixed shaft V, and of the fixed disk L, is shown in Figs. 11 and 12. Owing to its multiple division, the matrix opens very easily, as may clearly be seen in Figs. 12, 13, and 14, while the closure of the matrix is effected by its tapering side surfaces in passing back into the tapered sockets B of the disk B in consequence of its own weight and by the pressure of the die. The lower heads of the matrices in bearing upon the cam-disk L during their rotation cause the matrices to be displaced radially toward the outside, and they prevent the matrices from falling out when they have arrived at their lowest position.
The hook nail or spike is manufactured from the blanks obtained, as shown in Figs. 2 to 8, in the following way: The blank V is introduced by a workman into the matrix C, (see Figs. 10 and 11,) andthe disk Bis caused, by eccentric E, rod S, lever H, pawl K, and
ratchet-wheel R, to make a quarter of a revolution in the direction shown by the arrow, while the eccentric makesawhole revolution. The blank contained in the matrix is forced by the die D at the descendinginotion by the second eccentric into the matrix and the point is straightened. The die moves upward, the disk continues its motion in the direction indicated by the arrow, and the matrix will be opened by its head sliding on the fixed cam-disk L, so that the finished hooknail falls automatically out of the opened matrix when the latter has arrived at its lowest position.
If it is desired to produce spikes of other shape, it is only necessary to substitute other matrices of proper internal contour for those herein shown and described.
Having described my invention, what I claim, and desire to secure by Letters-Patent of the United States, is
A machine for working and finishing spike blanks, consisting of a rotary wheel having outwardly-tapering sockets in its periphery, with sectional matrices therein, for spikeblanks, an eccentric disk located within the rotary wheel and acting on the rear of the matrices, a catch for holding the rotary wheel in fixed position, and a die with operating mechanism, substantially as shown and described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WILI'IELM BOECKER. Witnesses:
