Abstract: 245,720. Lebosse, A. F., Guyon, Y., and Marty, R. H. C. Jan. 6, 1925, [Convention date]. Materials, special, for bags, sacks, making.- Bags for storage and transport are made of iron and stool wire in a machine comprising a series of pairs of complementary semicylindrical segments aligned and housed in semi-circular recesses in the contacting surfaces of two-stage sliding members; the rotary movement being imparted by racks. The machine has pairs of similar segments arranged in an endless series, and housed in recesses formed in the contacting surfaces of concentric annular members which may be deformable or articulated, or of slides connected so as to allow an exchange of segments so as to produce a tubular netting all in one piece, the meshes of which are hexagonal and have four sides constituted by single wires and two opposite sides formed by wires twisted together for at least two half turns. In the form shown in Fig. 4, two rigid concentric annular members 1. 2 carry the segments in circular recesses 3. One member may be formed of supple material or of articulated members. In the form shown in Fig. 5, pairs 4, 5 of rectilinear or other members carry the segments and between the ends of the members, the segments are set in motion so as to produce an interlacing effect. In another form, Fig. 6, two pairs of slides 6, 7 and 8, 9 are formed with recesses to house segments 10 - - 33, members 34, 35 being adapted to reciprocate transversely of the slides, to bring the segments 10, 22 opposite the segments 33, 21 respectively, where they are given a quarter turn to bring them into alignment with the other segments. The segments 11, 21, 23, 33 are retained in their housings during the movements of translation by the arrangement shown in Fig. 8. A two part member 38, 39 is mounted to move in a bracket 37, and is formed with a recess housing a segment 40, so that, when the member 34 moves away with the segment 10, the part 38 is impelled by a spring 41 to take its place and to bring the segments 11, 40 into register. These segments are then turned and the slide 6 advances and pushes the member 38 to the left against the action of a spring 42, to bring the next segment 12 into register with the segment 11. In the form of apparatus shown in Figs. 12 and 15, two pairs of parallel slides 43, 44 and 45, 46 carry segments 49 - - 55 and 67 - - 72. Members 47, 48 are connected to each other by a link, and to the slides 43, 46 respectively by oblique links. The slides 43, 45 and 44, 46 respectively move in synchronism and may be integral. The slides move in the direction of the arrows in Fig. 12, until the segments 54, 55 engage each other and both engage a rack 73, Fig. 15, carried on a support 74. The segments 47, 48 are then free to move transversely and they move as one to transfer the segment 54 to the line 70, 72 of segments. In the succeeding movements of the slides the following pairs of segments are brought into registry, 51 and 53, 68 with 72 and 54 with 69. The support 74 of the rack is guided by pins 75, 76, the portions 56, 57 of the members 47, 48 being formed with grooves 78, 79 so that the segment 55, which carries no wire, is continuously engaged by the rack, while the wire carrying segment 54 engages at the beginning of the transverse movement, rotates, and disengages. The Specification as open to inspection under Sect. 91 (3) (a) states also that in addition to more ordinary forms of wire netting, forms such as are shown in Figs. 1 (Cancelled), 4<a> (Cancelled), and 4<b> (Cancelled), may be employed for making the bags. This subject-matter does not appear in the Specification as accepted.
