DIE FOR MANUFACTURING THE TONGUES OF CAR-COUPLINC:`|S.4
SPECIFICATION forming part of Letters Patent No. 256,147, dated April 11, 1882.
Application filed July 2l, 1879. Renewed October 26, 1881. (Model.)
To all whom it may concern Beit known that I ,WAELLIM C. KROEGHER, of Allegheny, in the countyof Allegheny, State of Pennsylvania, have invented a new and useful Improvement in Dies for Manufacturing the Tongues of Car-Couplings and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the let-ters of reference marked thereon.
My invention relates to an improvementin dies for manufacturing rotary hooks or tongues forming part of car-couplings; and the invention consists in the means, hereinafter described, for giving the desired contour and reduction to the proper size of the rotary hooks or tongues of the-couplings.
To enable others skilled in the art to make my invention, I will proceed to describe .the manner in which it is carried out.
In the accompanying drawings, which form part of my specilication,Figure l is a top view of the base-die. Fig. 2 is a vertical section of the same. Fig. 3 is a top view of a die placed withinA the base-die. Fig. 4 is a side view of the same. Fig.5 is avertical and longitudinal section ofthe same. Fig. 6 is an inverted view Of the upper Or moving die. Fig. 7 is a side view of the same. Fig. 8 is a top view of the rotating hooked tongue B. Fig. 9 is a side viewof the same. Fig. 10 is a vertical and longitudinal section of the several dies and said tongue arranged in juxtaposition.
The tongue B is forged into a form approaching that represented in Figs. 8 and 9, so that it can be readily entered in the cavity of the die A. The die B being placed in the die A, as indicated in Fig.10, the partially-formed tongue is heated to about a welding-heat and placed in the cavity of the die A. The die C is then placed over the cavity of the die A and resting upon the heated and partiallyformed tongue,(indicatedbyeinFig.10.) Then, by a series of strokes of a Sledge-hammer, the tongue B is swaged to the form and size desired. The key D (shown in Fig. 10) is then driven through, as indicated by the dotted lines h in Fig. 2, which will loosen up the die B and the tongue (indicated by the letter e) so that it can be readily removed from the dies A and B.
The part of the upper die (marked f) forms the recess g in the tongue B. The upper die may be secured in a drop or to the helve ofy a steam-hammer, and the lower die is secured in a proper position to an anvil arranged with relation to such drop and helve ot' the steamhammer, the latter method of operating the dies A and C being preferable.
By manufacturing the tongue B in the manner and by the means hereinbefore described it will be swaged to the proper size and desired WAELLIM C. KROEGHER.
