Title: Improvements in or relating to signature feeding arrangements for use in book stitching machines
IPC: B42B2/00
Filed: 1937-03-09
Abstract: 472,677. Feeding signatures. COLDITZ, L., (trading as BREHMER, GEB.). March 9, 1937, No. 6964. Convention date, March 11, 1936. [Class 100 (i)] In book-stitching machines of the kind in which the signatures are fed at high speed by means such as pusher members on a chainconveyer C, Fig. 1, to a swinging stretching saddle S, a guide is provided movable with the saddle, to guide the signature as it is being placed upon the saddle, and to restrain the signature during the working stroke of the saddle, and finally moving clear of the signature so as to avoid further contact therewith during its return movement with the empty saddle. The saddle S comprises plates 12, 13 supported by oscillating arms 14, and presents the signatures successively to a stitching mechanism M for stitching to a continuous book pad P which is progressed along a trough table 11. A guide bar 20 is arranged to be constantly maintained parallel with and slightly spread away from the rear saddle plate 13, forming a guide channel to receive the inner limb 26 of each signature B; the outer end of the bar 20 is provided with a curved nose plate 20a, Fig. 3, to direct the incoming signature. The guide bar 20 is provided at its ends with rollers 21 running freely in slotted guides 18 secured to the arms 14, parallel with the plate 13, and is supported by a parallel-motion linkage 22, 23 pivoted on the table 11 and loosely coupled to the bar 20 by means of pins 24 and slots 25. During the swinging movement of the saddle, the bar 20 moves parallel with the saddle plate 13 in a horizontal plane below the level of the table 11, and so that it is clear of the path of the signature before the latter reaches the stitching position. Since the linkage 22, 23 is carried by the table 11, the bar 20 will be automatically adjusted relatively to the lower edge of the signature as the table 11 is adjusted normally for different widths of signature. When the bar 20 is fully retracted, a pair of upstanding fingers 27 on it enter slots 28 in the table 11 and press back the book-pad the thickness of one signature. The fingers 27 have curved front faces to facilitate their withdrawal from behind the lower edge of the last stitched signature in the return movement of the empty saddle.

Title: Improvements in or relating to the manufacture of insulated electrical connectors
IPC: H01R43/24
Filed: 1963-02-26
Abstract: 967,041. Cable joints; two-part couplings. NORTHWEST INDUSTRIES Ltd. Feb. 26, 1963 [May 31, 1962], No. 7752/63. Addition to 889,080. Heading H2E. The parent Specification describes a method of insulating the connection between cables and terminals mounted in an insulating member, comprising locating a flexible ring round the cables, placing a split die round the connections so as to embrace the insulating member and compress the ring, thermoplastic material being then injected into the die so as to surround the connections, such material, when set, locking the insulating member and ring in position. In the present Specification the flexible ring is replaced by a flexible member (having individual apertures for each cable) and the resinous material injected into the die forms a molecular bond with the materials forming the flexible apertured member, cable insulation and the insulating member, locking them in position. Figs. 2 and 3 show a doubly insulated wire 10 soldered to socket 11 and homogeneously bonded to the primary insulation by a moulded casing 15. Four of the encased connections are passed through apertures in an insulating member 20 and an apertured member 22 and placed in a mould 24 (Fig. 5, not shown) into which is injected a molten synthetic thermoplastic material which is the same as the material of the secondary insulation, the insert spacer 20 and grommet 22. Due to the heat and pressure developed by the injection moulding the secondary insulation, insert spacer and grommet are softened and upon cooling a molecular bond is formed. This insulated connection 28 (Fig. 6, not shown) is then placed in another mould 29, and a sealing grommet 31 is placed on the insulated connection 28 to maintain the moulding pressure during the injection moulding, thus an environmental proofed electrical connector. Fig. 8, is formed. Although two injection moulding processes were necessary for this embodiment it is possible to effect only one injection moulding step to reach Fig. 8 provided the components are supported within the larger mould, for example by a positioning cage, as shown in Fig. 12. These embodiments may be used to form male or female connections with single or two-ply insulated wire. Figs. 17-22 (not shown) illustrate a similar sequence of steps which insulate connections for cables having two ply insulation and earthing screens of metal braid, a terminal 80 for the earthing screen 67 being provided which passes through the insulation formed around the connection. Figs. 23-27 (not shown) illustrate further embodiments of the positioning cage or insulating member, i.e. a cylindrical, rectangular or strip member having a plurality of slots and holes for the insulated wires. Figs. 15 and 16 (not shown) illustrate two ways of assembling mating male and female connectors i.e. using a coupling nut and a coupling ring or a moulded coupler. Specification 955,216 also is referred to.
