Title: Improved device for the formation of eyes at the ends of coiled springs
IPC: B21F35/00
Filed: 1957-10-15
Abstract: 809,737. Deforming ends of coiled springs. SPUEHL A.G. Oct. 15, 1957 [Nov. 23, 1956], No. 32113/57. Class 83 (4). A device for forming an eye at the end of a coiled spring comprises a body, mounted rotatably but restrained axially, formed on its end face with a groove to accommodate part of an end turn of the coiled spring, and an abutment arranged immediately above the said end face preventing the emergence from the groove of said end turn during its deformation into an eye consequent upon the rotation of the said body. An eye forming body 5 is rotatably mounted in a member 1 having fixed and movable jaws 2, 3 which hold together two end turns 8 of cushion springs which are to be connected by a helical or coiled spring 7. An upper face of the body 5 is formed with a groove 6 in which the helical 7 lies as it is advanced screw-wise through the end turns 8. An edge 9 of the groove 6 is formed as a knife and a counterknife 11 is arranged immediately above the end face of the body 5, its underside preventing emergence of the helical 7 from the groove 6 during formation of the eye. As the body 5 is rotated counter clockwise, Fig. 2, the helical 7 is first cut and the cut end in the groove 6 is then bent round to form an eye, the body 5 rotating 180 degrees. For forming an eye on the end of a spring no knife edge is provided on the groove 6 or member 11, which latter is in the form of an abutment covering the groove 6 in its initial position. After rotation the groove 6 is not under the abutment 11 and the helical 7 may be lifted out. A device is acknowledged as prior art in which a coil passes through a transverse bore in a sleeve and a rotatable body formed with a groove in its upper end face is moved up axially in the sleeve to engage the coil and then is rotated so that an edge of the groove co-operates with a counter knife to cut and to bend the cut end.

Abstract: 1,269,709. Telegraphy. ING. C. OLIVETTI & C. S.p.A. 2 July, 1969 [2 July, 1968], No. 33386/69. Heading H4P. Each line of characters transmitted, equivalent to a printed line, is checked to ensure that the line contains preset characters at positions defined by a line format generator. As described the preset characters are all "Space". After the operator transmits a start code to a remote unit, e.g. a concentrator, a reply is received which causes a control unit at the transmitter to unlock a format keyboard whereby the operator can select one of, e.g., 7 formats with which the line of characters to be transmitted must agree. This format information is passed to the control unit. Alternatively the operator indicates to the control unit that the line format is unrestricted. The control unit now unlocks the main keyboard and the operator keys in and transmits the characters. The format generator comprises a counter which steps whenever a character is sent and places pulses in turn on each of the 80 (=the number of characters in a line) inputs of a connection matrix, which delivers at each of 7 outputs, corresponding to the 7 possible formats, a pulse whenever the count reached corresponds to the position in the line format at which the operator should key a "Space". The appropriate one of the 7 outputs is selected and passed to an EXCL-OR gate. This gate receives a pulse on its second input whenever the operator keys a "Space" or Carriage Return. Consequently the gate outputs a pulse if the character keyed at the positions determined by the selected output of the format generator is not Space. This error pulse passes to the control unit. The connection matrix also delivers on each of 7 outputs a pulse whenever a character position in the corresponding format is reached at which the last character should have been a "Space" and the present character is unrestricted. The appropriate one of these outputs is connected to the control unit. At the end of a line the main and format keyboards are locked and, if no error has occurred in the format or during transmission, the remote unit sends a reply signal which causes the format keyboard to be unlocked and the procedure indicated above to be repeated for the next line. If the EXCL- OR shows there has been a keying error an error indicating sequence is transmitted automatically, and the keyboards are both locked for a preset time, after which the format keyboard is unlocked and the line keyed again as described above. If the remote unit detects parity error in the signals it receives it sends to the transmitter a signal which causes the control unit to lock both keyboards. The line of characters is then keyed again as described above.
