Title: Improvements in or relating to garment and like presses
IPC: D06F71/22
Filed: 1932-07-26
Abstract: 400,375. Ironing presses. WHITEHEAD, H., 74, Avenue Road, Acton, London. July 26, 1932, No. 21020. [Class 138 (ii).] The recess in one or both ends of a work support of an ironing-press into which a portion of a garment not to be ironed is turned (for example a shirt collar-band) is bounded by a flange which extends upwardly so that one side of the flange defines the recess whilst the portion of the garment immediately adjacent the part not to be pressed lies on top of the flange. The recess may be provided in the press buck itself or, as shown, in a fitting removably secured thereto. A plate 22 in the shape of a V having a rounded apex is resiliently supported above a plate 16 so that the flange 24 on the plate 22 registers with the inside of the U-shaped recess in one end of the plate 16. The plate 22 is supported by springs 30 secured to the plate 16 and engaging holes in the underside of a rib 26 formed on the underside of the plate 22. Pins 34 are provided for securing padding to the plate 16 and apertures 36 are formed in the plate 22 to permit the passage therethrough of certain of the pins 34 when the plate 22 is depressed. A pin 32 is secured to the flange 24 and enters the buttonholes of a shirt collar-band, the latter being turned down and accommodated within the V-shaped recess. When the support is to be used for pressing articles other than shirts the recess may be filled by swinging into the horizontal position a flap 42 on which padding is secured by pins 44. The plates, which may be bowed to conform to the curvature of an existing support, are secured to such support by means of metal straps 18 secured to the plate 16 and passing under the existing support, the ends of the straps being drawn together by a spring. In modifications the slidably mounted plate is dispensed with and the flange is formed around the V-shaped recess in the plate 16, and apertures or grooves may be formed in such flange to permit the escape of vapours or to facilitate the passage of threads for securing the padding. Two pins 32 may be used so that there are no overlapping parts of the shirt front.

Title: Forging hammer
Inventor: HASSEL HARALD
IPC: B21J7/34
Filed: 1961-06-12
Abstract: 986,389. Forging. EUMUCO AKTIENGESELLSCHAFT FUR MASCHINENBAU. June 12, 1961, No. 21196/61. Addition to 983,403. Heading B3H. An hydraulically operated hammer according to the parent Specification has a pair of tups 2, 3 interconnected by an oscillatable liquid link. The tups are connected to pistons 6, 7 whose spaces 8, 9 are in continuous communication with a container 10 filled exclusively with pressure liquid and which is charged by the constant delivery pump 11 through one-way valve 13. A by-pass valve 14 is operated when the hammer is idle. Cylinder spaces 18, 21 communicate with a reversing valve 17 which is connectible through a shut-off valve 23 with the reservoir 24. To initiate the forward stroke, pump 11 pressurizes container 10 until pressure controller 30 actuates valves 17, 23 to place cylinder space 18 in communication with the container 10 and space 21 with the reservoir. Thus upper tup 2 moves downwardly due to the differential pressure on its piston, and lower tup 3 is raised by the pressure in chamber 9. Shortly before impact one of the tups actuates an electric device which reverses valve 17 whereby space 18 is opened to exhaust and space 21 to the container 10. Thus upper tup is raised by the pressure in space 8 and the lower tup falls by gravity in opposition to the differential pressure on its piston 7. Buffer pistons 27 operate in spaces 26 connected through one-way valve 28 with the container 10 whereby the impact energy of the lower tup assists in pressurizing the container. A safety valve 31 is fitted. In another embodiment, Fig. 2 (not shown), horizontal counterblow hammers have the inner cylinder spaces of their pistons connected continuously to the container and the outer spaces to the reversing valve. Buffer pistons provided at the other ends of both cylinders are biased so that they move the working pistons to a predetermined adjustable starting position.

Each carriage 15 is guided along beam members 19 by rollers 29, 31 and has a motor 33 which drives pinions 23 engaging racks 22 mounted on the beam members 19, Each paddle 16 is rotated by a respective motor 111 and is carried on a cross-bar 49 secured to the arm 17. A first press wheel 106 for engaging the roll 11 is mounted coaxially with the paddle 16, and a second press wheel 119 is mounted for limited pivotal movement on the other end of the bar 49. The carriage 15 is connected to the top end of a piston (80, Fig. 4), received in a cylinder (73) secured at its lower end to a slide member (57, Fig. 5), guided for vertical movement with respect to the carriage 15 by rollers (69, 70) which engage tracks (66) in the carriage 15. The arm 17 is guided for vertical movement with respect to the slide (57) by rollers (61, 62) engaging tracks (62, 63) on the slide (57). A pair of chains (93) are connected at one end to the arm 17 and at the other end to the carriage 15, and pass over double sprockets (88) mounted on the slide 57. Thus, as the slide (57) is raised or lowered, the arm 17 is raised or lowered at twice the speed of the slide (57). When not in use, the carriages 15 are positioned centrally of the beam 13 adjacent stops 51, with the arms 17 retracted. For a wrapping operation, the arms 17 are lowered until arms 50 pivoted to the arms 17 and carrying rollers 137 engage the roll 11 and are pivoted, against the action of torque actuators 136. This operates a limit switch 56 to terminate downward movement of the arms 17 and initiate movement of the carriages 15 towards the ends of the beams 13. At the ends of the roll, the arms 50 are pivoted downwardly by the actuators 136 to recommence downward movement of the arms 17. The wheels 106, 119 engage the roll, to cause arms 127 carrying the wheels 119 to pivot upwardly and operate a switch 126 for the initiation of the crimping operation.
