DIE FOR FORGING SHlFTlNG-RAILS.

SPECIFICATION forming part of Letters Patent No. 394,232, dated December 11, 1888.

Application filed June 8,1888. Serial No.2'76,4=57. (No model.)

To all 2071 0711 it may concern:

Be itknown that I, AD-OLPH \V'ALTER, a citi- Zen of the United States, residing at Athens, in the county of Athens and State of Ohio, have invented certain new and useful Improvements in Dies for Forging Shifting- Rails; and I do hereby declare that the following a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a perspective view of my improved die sections, the upper one of said sections being elevated to show the inner sides or faces of the section, and Fig. 2 a view showing the back rail-section in its several steps of completion.

The present invention has relation to means for the manufacture of carriage or buggy shifting-rails, and it refers more particularly to the manner of producing such rails by means of suitably-constructed dies, for which a patent was granted to me November 23, 1 886, No. 353,100. These dies in the above-described patent were especially designed for the production of the side shifting-rail sections; and the object, therefore, of the present invention is to provide suitable dies for forming the back rail section, by which said section and the corner iron thereof is forged complete; and the invention consists in dies constructed substantially as shown in the drawings, and hereinafter described and claimed.

In the accompanying drawings, A B represent the two sections of the die, between which the back section and corner iron of the shifting-rail is formed into shape, said die-sections, if preferred, having suitable serrated faces, a, to prevent the bar of iron, when placed between the die-sections, from slipping, as in my former patent. The bar of iron, which is of suitable shape to form the back section and corner iron of the shifting-rail, is taken from the furnace and placed upon that portion of the die-section B, (indicated at 1),) said bar extending longitudinallyover the face of the die-section and one end resting on the anvil c, and the other end of said bar resting over and upon the serrated surface a of the lower section of die.

The diesection A is now brought down over the die-section B and over and upon the iron bar, and by suitable trip-hamm er or other wellknown means pressure is brought upon the upper die-section, which forces the metal of the bar into the depressions d c of the die-sections A B, respectively, and also the depression f of the upper one of said sections, which is at or near the corner thereof, so that when the two sections of the die are brought together the depression f will be in the rear of the anvil c to form the lug g, while the depressions (l e form the lugs 72 -1', respectively, as shown at C- in Fig. 2. The corner of the die-section A has a depression,], which joins the depression f, and is of form and shape to correspond with that of the anvil 0, whereby the corner iron of the back section is produced. The bar, after having been forged into shape, as shown at C, Fig. 2, is removed from the dies and again placed between them, so that they will rest between the grooves m m of the die-sections A B, respectively, when they are brought to gether, the lug h resting over the grooved eX- tension 91, and the lug i resting over the grooved extension 0, and the lug g resting over the grooved extension 3, and the exten sion 0' of the bar resting over the grooved extension s, and in this position the upper diesection is brought down thereon to forge the bar into shape, as shown at D, Fig. 2, after which the bar thus shaped is again acted upon by the dies. The groove m, as should be understood, has correspondingly-f0rmed extensions, n o p s, to those of the groove m. The bar, in the shape as shown at D, Fig. 2, is now taken and placed over the groove t, which also has grooved extensions u 'v w a", of the forms shown, and correspondinglyformed groove, t, with extensions to 'v w 0:, is pro vided upon the die-section A, whereby the blank D, when acted upon by the two die-sections, is forged into shape, as shown at E, thereby forming the back section and corner iron of a shifting-rail complete.

In place of the lugs hereinbefore described, holes may be made through the rail, as found most desirable.

too

and at their corners an anvil and a depression of corresponding form, said anvil and depression being located at the extreme corners of the die-section and the depression joining one of the depressions which form the lug, substantially as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two Witnesses.

ADOLPII VALTER.
