WILLIAM EVANS, OF PHILADELPHIA, PENNSYLVANIA.
IMPROVEMENT IN THE MANUFACTURE OF SPRINGS.
Specication forming part of Letters Patent No. 133,424, dated November 26, 1872.
' To all whom it may concern:
-city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in the Manufacture of Springs and in Dies for the same, of which the following is a specification:
My invention consists of a mode or process, too fully explained hereafter to need preliminary description, of forming the heads or sockets of carriage-springs so as to insure strength and solidity. My invention further consists of certain apparatus, described hereafter, whereby the pieces comprising the said ends or sockets may be quickly produced.
In the accompanying drawing, Figures l and 2 are perspective views of a strip of springsteel with cheek and filling pieces attached to the same prior to the formation of the socket or head of the spring; Figs. 3, 4, and 5, perspective views of the cheek and filling pieces; Figs. 6 and 7 views of finished sockets or heads 5 Figs. 8 and 9, views of the reversible punch and adjustable die for forming the cheek-piece shown in Fig. 3; and Figs. 10 and ll, views of the same punch and die as they appear when arranged to form the smaller cheek-piece illustrated in Fig. 4.
The portion of a carriage-spring to which my invention relates is represented in Fig. 6, and lconsists of a strip of spring steel, A, hav- `ing at the end a head or socket, B, in the sides a a of which are bolt-holes b. I form this, the ordinary head or socket, in the following manner: I take aflat strip, A, of spring steel, such as represented in Fig. l, and to the opposite side of the same I t crude cheek-pieces D D, each having a iiange, d, and two lugs, e e, so arranged that the edge of the strip A will fit tightly between them. The cheek-pieces are formed by a punch and die of the peculiar In forming the head or socket I also use a triangular filling-piece, E, which may be cut from a rolled bar of corresponding shape, and which is placed upon the strip A between the cheekpieces' and fitted at its opposite ends into re'- cesses f formed in the said cheek-pieces. (See Fig. l.) When the several parts have been thus fitted together they and the end of the strip are brought to a welding-heat, and then,
. by ewa-ging, are reduced to the shape of the head shown in Fig. 6, the cheek-pieces a a becoming the sides a. a, Fig. 6, and the fillingpiece E becoming the mass of metal c which tapers gradually into the strip A. The swages for thus shaping the metal may be of the usual construction, and, therefore, require neither illustration nor description. The head' is nished by punching vthe holes b, and by filing and by finishing in the usual manner. The head represented in Fig. 7 is shorter and `joins the strip A more abruptly than that represen ted in Fig. 6, so that shorter cheekpieces D', Figs. 2 and 4, can be'used. In making this head the filling-piece E is also fitted somewhat differently to the cheek-pieces and strip, it being recessed at the ends, as shown at h, Fig. 5, so that it can be fitted over the lugs e at the inner edges of the cheek-pieces instead of into recesses in the latter. The parts thus fitted to the strip A will, when welded and swaged, form a head united abruptly to the strip A, as shown at S, Fig. 7, instead of merging into the same, as shown in Fig. 6. The cheek-pieces D and D', for the two kinds of springs illus trated, are alike except as regards length, and can be formed by the same punch and die, as I will now proceed to describe. The punch F, Figs. 8 and 10,'s reversible, one end, X, be-
ing adapted to the formation of the cheekpieces D, and the opposite smaller end Y to the formation of the shorter cheek-pieces D', and in each end X and Y are recesses w and y corresponding to the lia-nge el and lugs e e of the cheek-pieces. The die G consists of a frame, to guides on which are adapted four sliding pieces or sections, 7c 7c' and m m', the latter being inserted between the former, as shown in Fig. 9, so as to form an opening, z, corresponding in dimensions and shape with the end X ofthe punch when the large cheekpieces D are to be formed. When the smaller cheekpieces D', however, have to be made, the punch is reversed, as shown in Fig. 1l, the sections m m' of the die drawn back, and the sections 7a k' brought together, as shown in Fig. 10, so as to form an opening, z', corresponding in size and sh ape with the said short cheekpieces and end Y of the punch.
I claim as my invention-- 1. As an improvement in the manufacture Q i 133,424 l of springs for vehicles, Welding together and i In testrnonywhereof I have signed myname to the strip A the cheek-pieces D D and to this specification in the presence of two sub` cross-piece E, the said pieces being adapted scribing Witnesses. to each other and to the strip, substantially WILLIAM EVANS. as set forth.
2. The die G,`composed of the adjustable Witnesses: sections 7.: k and sections m m', as set forth. WM. A. STEEL,
3. The combination of the said adjustable HARRY W. DOUTY. die with the reversible punch F.
