Abstract: 435,824. Boots &c. DETACHABLE HEEL & ARCH PLATE CO., Ltd., 24, Hackins Hey, Liverpool, and GRIFFITHS, W. H., 311, High Street, Bangor, North Wales. May 9, 1934, No. 13959. [Class 17 (ii)] The leading edge of a detachable heel is protected by a turned-back portion of a plate member secured either to the detachable heel or to an inner sole or other foundation member of the footwear to which the heel is attached. In the form shown in Figs. 2 and 3, an inner sole 10 has fixed to it a plate member 12, part of which is cut out to receive a separate plate member 15 also secured to the inner sole 10. The plate member 15 is bent back out of the plane of the plate 12 and spaced therefrom to form a slot 46 for the reception of bent-back portions 17 of a plate member 18 secured to the detachable heel 20. The member 18 has a turned-back portion 29, which protects the leading edge of the heel and assists in securing the plate 18 thereto. The leading edge of the heel may be recessed to receive the turnedback portion 29. When the heel is in position in engagement with the inner sole, relative sliding movement is prevented by a pin 21 mounted on a spring plate 22 attached to the inner sole and fitting into aligned holes in the inner sole, plate members 15, 18, and in the detachable heel. During wear, this spring plate 22 is covered by a flap 28 of felt. The plates 12 and 15 may be made separately or in one piece, and either plate 12 or 15 may be made integrally with an arch plate 11, or all three plates 12, 15, and 11 may be made together in one piece. A modified form shown in Fig. 6 comprises a combined arch plate and plate member 30 for securing to an inner sole, and which has bent-back portions 32 adapted to engage with bent-back portions 35 on a heel plate member 33, Fig. 7, having also a turned-back portion 37 for protecting the leading edge of the heel. In this case, a substantially U-shaped staple inserted in holes 38 is used instead of the pin 21, its yoke being adapted to lie in a recess in the inner sole. The turned-back portion 29 or 37 shown on the plate members 18 and 33 may instead be formed on any of the plate members 12, 15, or 30 secured to the inner sole. The Provisional Specification states that the plate members of the heel and inner sole may have projections and recesses in the various forms described in Specification 408,115.

Title: Improvements in or relating to forging
Inventor: WISTREICH JOHN GEORGE
IPC: B21J7/30
Filed: 1960-04-22
Abstract: 947,863. Forging. BRITISH IRON & STEEL RESEARCH ASSOCIATION. April 20, 1961 [April 22, 1960], No. 14223/60. Heading B3H. [Also in Division G4] A circuit for controlling both a forging press and a forging press manipulator is characterized in that completion of an operation by one of the units initiates an operation of the other. The forging press is as described in Specification 874,908 and the forging press manipulator as in Specification 892,216, both of these Specifications being referred to. The control circuit is so designed that the press and the manipulator operate alternately with the minimum of delay between successive operations. This object is rendered difficult by the fact that while the manipulator responds to a signal initiating a rotational movement relatively rapidly, its inertia causes it to respond to a signal initiating a translational movement relatively slowly. This difference in response times is compensated for by actually producing a translation initiation signal before the press has completed its operation. The mode of operation of the manipulator is specified by a switch MSS having positions LON for longitudinal displacements, ROT for rotational displacements and HEL for helical displacements, i.e. combined rotation and translation. In the longitudinal displacement LON a relay position of the switch prepares a circuit for a relay P which when energized via a contact U3 initiates such a displacement in the manipulator. The contact U3 is so arranged that it closes its right-hand contact just as the press begins its downward stroke and thus the manipulator receives its initiation signal suitably in advance of when it is desired that the translation shall take place. For rotation a relay T<SP>1</SP> is energized via a contact S3 and the left-hand contact U3 which closes when the press starts its upward stroke and this causes the release of a normally-energized slow-torelease relay ID whose contact ID1 initiates a rotation. While the manipulator is in operation one of contacts 431, 441, &c. is opened and thus prevents operation of the press.

Title: Improvements in sewing machines
IPC: D05B35/02
Filed: 1927-05-27
Abstract: 291,229. Fletcher, E. May 27, 1927. Folding-devices. - A device for forming " turned " and similar seams of the kind having two transversely and oppositely reciprocating members 14, 18, is characterized by giving the members a relative opening and closing movement. The memhsrs 14, 18 are reciprocated by eccentrics 9 on a shaft 7. The member 14 reciprocates in a groove in the casing under the action of its eccentric 9 and link 12. The member 18. which mav be a serrated or threaded cylinder rotatably mounted in the boss 25, is connected by a link 17 to its eccentric. This link passes over a roller 19 so that as the eccentric rotates on the shaft 7, the member 18 is reciprocated, and moved up-and-down. The roller 19 is mounted on a bracket 20 and may be raised or lowered to vary the amount of vertical movement of the member 18 by an eccentric. The link 17 is pressed on to the roller by a spring 21 fixed upon a shaft 22 and the backward movement of the latter is prevented by a ratchet wheel. A chain 26 connects the needle bar 4 and link 17 so that when the bar is raided, the link and hence the member 18, are raised. The lower member 14 may have the up-and-down movement instead of the upper member, or both may have it.
