IPC: G06K15/06
Filed: 1968-07-19
Abstract: 1,248,249. Keyboard encoders. SCM CORP. 19 July, 1968 [21 July, 1967 (2)], No. 5604/71. Divided out of 1,248,247. Heading H4P. The description is substantially identical to Specification 1,248,247, but the claims are directed towards a keyboard encoder which derives a set of binary electrical signals corresponding to their decimal value. Depression of any digit key mounted on a portion 221A pivots a stem 203A about the shaft 206 which is limited in its upward movement by another shaft 205 forming an axis for stems 203B carrying portions 221B for function keys, e.g. symbols +,- &c. Each stem has approximately perpendicularly downwardly extending legs 209 which are joined in pairs by springs 210. Each key stem has an arched centre portion within which one or more selectively positioned actuators having integrally formed downwardly extending lugs 208, the width and position of which are arranged according to a code corresponding to a decimal digit function to actuate L-shaped bails 212-216, 222 which are positioned parallelly beneath the arched portions. The parallel legs 221 of each bail which also have downward legs 217 are also pivoted about shafts 205, 206 and are loaded by springs 210. The outside bails are reinforced by members 218, 219. Strobe bail 212 is actuated by all keys, function bail 222 is actuated only by function keys and numerical bails 212-216 by digit keys which through tabs (213A-216A), Fig. 8 (not shown), operate two position spring-loaded switches (223-226) each position representing " 0 " or " 1 " binary digit. The binary electrical channels controlled by switches (223-226) correspond to decimal values 1, 2, 4, 8 respectively, the binary coded form of each value being represented by actuation of a corresponding number of switches. In an alternative arrangement, Figs. 9 and 10 (not shown), lugs (261) on key stems (252) displace a captive ball arrangement comprising balls (242) running in parallel U-channels (259), the balls being closely spaced to prevent actuation of more than one decimal key at a time. A lock-out race-way operated by an electromagnet (263) may be provided to prevent information being entered when working from a data processor. In contact with an end ball is a spring- loaded lever (275), Fig. 11 (not shown), forming part of a bail (282) which through a button (277) actuates a switch (278). The signals may be passed through a mechanical decoder to a printer and may be also passed to an integral or separate electrical computer (see Specification 1,248,247.

Title: Improvements in or relating to welt sewing machines
IPC: D05B15/06
Filed: 1926-03-01
Abstract: 258,783. Reece Shoe Machinery Co., (Assignees of Oliver, J. R.). Nov. 10, 1925, [Convention date]. Boot-sole sewing-machines, welting and turnshoe.-A welt-severing knife is provided which moves at the close of a stitching operation in conjunction with a welt guiding member along the line of feed to a position substantially beyond the stitching point where the welt is severed so as to leave a projecting welt end. The knife is set in motion by the release of a latch on contact with part of a shoe. The welt passes through an elongated guide as described in Specification 250,547 and then through a separate part 25 which moves normally with the guide but during the cutting action moves, in unison with the knife, beyond the stitching point. The part 25 is carried by an arc shaped shank 27 to which it is pivoted at 28 so as to allow it to share in the pivotal movements of the guide which are transmitted by a slide pin 29. The knife 30 is mounted on an arc-shaped shank 31 which is supported together with the shank 27 in a guide member 35 supported by a laterally sliding bar 87. The knife is moved suddenly forward and then retracted these movements being communicated by an elongated pinion 33 engaging rack teeth 32. The knife and member 25 are moved in the line of feed, i.e. at right angles to the plane of Figs. 1 and 2, by a cam 39, Figs. 2 and 5 carried by a member 45 and engaging a pin 38 on the bar 37. The shaft 42 of the pinion 33 carries a pinion 43 meshing with a rack 44 on the member 45 which is slidably mounted and pivotally connected to the link 50 of a toggle 50, 51. The pivot 52 of the toggle is carried by a bar 58 surrounded by a spring 63 which is normally compressed and when released moves the bar 58 to the left so that the member 45 is moved downwards and then returned causing the advance and immediate retraction of the knife. The bar is withheld from movement by a latch 70 having a tail 71 which is struck by the toe of the shoe in order to initiate the cutting operation. The bar 58 is reset by a lever 75 which is normally oscillated idly by a link 77 connected to a yoke 15 embracing an eccentric 14 which operates part of the needle mechanism. After the bar has been released the lever 75 engages a head 59 thereon and returns the bar to latched position. This movement occurs without operation of the knife owing to the movement of a pin 53 in the link 51 out of a notch 55, which confines it during the operative stroke and into a slot 54. Specification 223,853 also is referred to.
