Abstract: 190,192. Spirella Co. of Great Britain, Ltd., (Spirella Co.). July 16, 1921. Making metal fabrics; corrugating.-In a machine for making fabricated wire, such as corset and like stays, having alternately oppositely-disposed parallel, converging or overlapping loops extending transversely of the fabric, the wire is fed upon and bent alternately round pins on two sets of horizontally and vertically movable carriers by a single member which is movable towards and from each set of pins, and also transversely thereto. In the form shown in Figs. 2 and 8, two pin carriers 10, 14, each having a pair of pins 8, 9, 12; 13 are secured to horizontally movable blocks mounted on a pair of slides 19, which are alternately raised and lowered in a housing 20 by a pair of grooved cams carried bv a shaft 2 driven by gearing from a belt-driven shaft 5. The shaft 5 may also have a hand-wheel for use in setting up or forming the initial loop. The upper faces of the.pin carriers are downwardly inclined from their adjacent edges, and the forward parts chamfered, as shown in Fig. 10. The member for feeding the fabric and bending the wire round the forward pin on the raised pin carrier consists of a tubular finger 27, which is secured to a hollow rod 29 reciprocated in a housing 31 by a cam, pitman 46, lever 47 and link 50, the wire 65 passing loosely through the rod and finger. The housing 31 is carried by a block 37, which is pivoted at 40 to the framing and is oscillated transversely after the completion of each loop so as to make the initial bend for the next loop as shown in Fig. 8, by one or the other of a pair of rollers 53, 54, Fig. 4, which are fixed to the respective carrier slides and engage inclined faces 55. 56 on the forward end of the block. During the first part of this motion both pin carriers are in their raised position as shown in Fig. 8. During the forward movement of the finger to complete the loop, the raised pin carrier is forced rearwardlv by a shoulder 64 on the finger in order to feed the fabric through the machine, the carrier being returned when in its lowered position by a spring. The fabric is held on the pins until the pin carriers are lowered by one or other of the bevelled surfaces 66, 67 on a die 57, which is provided with an angular stem 59 and is pressed forward in an angular housing by a spring 61, the compression of which is adjusted by a screw 63. Set screws projecting from the casing engage each side of the die so as to locate its position. In order to permit of vertical adjustment of the finger, the housing 31 is pivoted at 36 on the block 37 and is adjusted at the other end bv screws 39. To adjust for wear of the housings the wall thereof is split through at one side and partially split at the other side and is secured bv bolts. In a modification, the portion of the framing on which the block 37 slides may be inclined downwardly towards the pin carriers. In a further modification, the pin carriers may be returned to their forward position positively instead of bv springs, being provided on their sides with grooves having inclined faces which engage the inclined faces of tongues projecting from the sides of the housing 20 during the lowering of the carriers. Specification 157,391 is referred to.
