METAL-SWAGrING-4 MACHINE.
Patented Jan. 21, 1908.
Original application filed December 22, 19051 Serial No. 292.946. Divided and this application iiled November 26, 1906. VSerial No. 345.020.' Renewed October 21, 1907. Serial No. 898,504.
T o all whom it may concern.'
Be it known that I, WILLIAM FEHR, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Metal-Swaging Machines, of which the following isl a specification.
My invention has relation to a swaging machine; and in such connection it relates particularly to the construction and arrangement of such a machine and being a division of an application filed by me under date of December 22nd, 1905, Serial No. 292,946.
The principal objects of my invention are first, to provide a metal swaging machine with means to swage or spread metal strips or wires such as are used in the manufacture of heddles either at the ends of slots punched to expand the same into eyes and mortises of required width or to expand the meta-l strip or wire into the required width of mortises and eyes prior to the slotting or piercing thereof; second, to provide the swaging machine with a hammer of a weight sufficient when descending by gravity to deliver a blow to permit a tool carried by the hammer in conjunction with a second tool held in a fixed position to expand or spread the metal to the width required; third, to provide the swaging machine with means to limit the movement of the hammer so as to control the extent of the swaging of the metal; and fourth, to provide the swaging machine with means to guide the metal strip or wire so as to insure the swaging of the same in the longitudinal central axis thereof.
The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof,
in which Figure 1, is a view, illustrating in side elevation a swaging machine, having a swaging hammer, means for raising the hammer and permitting the same to descend by gravity, means for actuating the raising means of the hammer, means for limiting the downward movement of the hammer and guiding means for a metal strip or wire, all embody-l ing features of my invention. Fig. 2, is a front elevational view of the machine. Fig. 3, is a view illustrating the machine in longitudinal central section. Figs. 4 and 5 are views illustrating respectively, in longitudinal section and in top or plan view a guide for the metal strip to be swaged. Figs. 6 and 7 are similar views illustrating respectively, in front elevation and in cross-section swagingor expanding tools used in conjunction with a portion of the, swaging machine supporting the same. Fig. 8, is a view illustrating in section means for limiting the downward movement of the swaging hammer, and Figs. 9 and 10, are views, enlarged, illustrating in elevation the metal strip prior to and after the swaging operation.
Referring to the drawings g, is a support or bed-plate, to which by means of a threaded bolt g3, is removably secured the swaging tool g1, forming an anvil for the metal strip b, which is fed forward by mechanism7 not shown. By this forward movement the metal strip b, is brought with a slot previously formed directly above the tool g1. Above the tool g1, and held in alinement with the same by a support g4, is arranged a second tool g2, forming in conjunction with the support g4, a hammer which delivers the blow necessary to expand the metal strip in the present instance at the respective ends of slots b1 and b2. By spreading the metal at these points, the slots formerly oblong in outline, as shown in Fig. 9, are now transformed into slots of oval outline, each having at its respective ends a rib-like portion b3, as shown in Fig. 10. In order to form these rib-like portions b3, each of the tools g1 and g2, taper as at g4, towards their free ends and are slightly curved at the same to form when the tools contact with each other abutting portions g5, and by their outwardly flaring portions g, wedge shape indentations gl, which permit of the formation of the rib. The metal of the strip b,'is compressed by the flaring portions g", of the tools g1 and g2, which thus the tearing of the metal at the ends of the slots otherwise occurring when the metal is not strengthened in the manner hereinbefore described. The upper tool 92, by means of a threaded bolt 93, is removably 4`secured to the 'strip b, into mortises and an eye of the ref quired width. The means for raising and then permitting the hammer 94, to drop, consists of bell-crank lever 92, pivotally secured to the y point 91, to a bracket 912, formed integral with the support 9, and bearing with its arm 911, against a projection 913, of the .hammer 92. The projection 913, in the point 914, is pivotally secured to a bracket 915, formed integral with the support 9, and thus the hammer support 94, has a range of 'oscillating movement in the bracket 915, which is imparted to the same in an upward direction by a cam a4, secured to a driving shaft 0,1, and engaging a roller 91, of the lever 99, in a downward direction by gravity, as soon as the roller 91, leaves the highest part a5, of the throw portion of the cam a4, as shown in Fig.. l. However, the downward movement of the support 94, and its tool 92, forming a hammer is limited by a threaded bolt 917, abutting with its lower end against a bolt 912, arranged in the support 9, of the swaging mechanism, as shown in Figs. 1 and 3 and 8. Thus the downward movement of the tool 92, is limited at the moment its portion 9, is brought in proximity with the portion 95, of the tool 91.
In order to insure the swaging oi' the metal strip b, at the ends of the slots b1 and b2, and in the longitudinal central axis of the same, the metal strip is conducted through guides 912, arranged at each side of the tools 91 and 92, as shown in. Fig. 2. Fach of the guides 912, consists preferably of a bar 92, adjustably secured to the support 9. The bar 920, is provided with an adjustable guide 921, extending in the path'of the metal strip b, and forming a rigid guide for the same; Opposite the guide 921, and limited in its movement by a projection 925, of a plate 924, secured to the bar 92, is arranged a yielding guide, consisting of a leaf-spring 922, abutting with its downward projecting end 923, against the strip t, as shown in Fig. 4. At its lower end the bar 5920, is preferably secured tothe support 9, as
shown inFigs. 1 and 2. Thus the guide 922, by yielding enables portions of the metal strip b, differing in width to readily pass between the guides 921vand 922. In this manner the metal strip b, is prevented from jamming between these guides and is held by the same irrespective of varying width, in a position which insures the swaging of the strip in the longitudinal central axis thereof.
Instead of swagmg the metal strip t, after the punching of the slots b1 and b2, therein, the swaging of the same may take place prior to the punching of the slots. This swaging prior to the punching is necessary, when a wire in place of a flat narrow strip of metal is employed to form the heddles. In this instance, the wire has first to be flattened by the tools 91 and 92, at the portions in which the mortises and eyes are to be formed to spread or expand the same to the required width.
Having thus described the nature and obj jects of my invention, what I claim as new and desire to secure by Letters Patent is 1. In a machine of the character described, a support having a'tool forming an anvil, a second support having a tool forming a hammer at one side and a depending projection at the other side and pivotally supported at a point between the hammer and projection and in proximity to the pivot by said first support, a bell crank lever pivotally connected with said first support. and contacting with said. projection, a cam-having an. inclined. throw portion and a depression, means carried by said lever and contacting with said cam, said cam andl means cooperating to impart to said lever and by the same to said second support and its vtool a gradual upward movement and to permit of a quick descent by gravity when said means descend into the depression of said cani to form in a metal strip passing between the tools, depressions from opposite sides'thereof.
2.V In a machine of the character described, a support having a tool forming an anvil, a second support having a tool forming a hammer pivotally supported by said 'first support, and a depending portion on the side of the pivot op osite the hammer, a bell crank lever pivotal y connected with said first support and contacting with said projection, a
cam having a gradually inclined throw portion and a depression, and a roller carried by said lever and contacting with said cam, said cam and roller cooperating to impart to said lever and by the same to said second support and its tool a gradual upward movement and to permit of a quick descent by gravity when the roller descends into the depression of said cam to swage the slotted end portions of a metal strip passing between the tools from opposite sides thereof.
In witness whereof, I have hereunto affixed my signature in the presence of two sub-
