Title: Safety guard device for a power press
Inventor: PLATT JOHN
IPC: F16P3/04
Filed: 1950-08-28
Abstract: 712,094. Machinery guards. SINGER MANUFACTURING CO., Ltd. Nov. 16, 1951 [Aug. 28. 1950], No. 21175/50. Class 80 (4) In a guard for a power press comprising one or more gates 9 which, on foot operation of a valve 10 are closed by a hydraulic piston in a casing 2, the piston in turn acting as a valve for hydraulic means 12 controlling the press, the gate 9 is held closed while the press is operating by further hydraulic means controlled by a rotating cam. The casing 2, Fig. 5, contains an actuating cylinder 4 and a holding cylinder 5, with a common piston-rod 8, and fluid is admitted through the valve 10 to the cylinder 4 to move the rod 8 to the left and close the guard. This movement uncovers a port 11 in the cylinder 4, thereby supplying fluid to the press-controlling means 12. As the press commences to operate a cam 18, Fig. 3, is rotated, to move a spring-loaded plunger 17 to allow an exhaust valve 15 to close and to open a valve 14 which supplies. fluid to the cylinder 5 to hold the rod 8 in the guard-closed position. A plate 19 eccentrically pivoted to the cam 18 has a lobe 20 co-operating with a fixed abutment 21 so that the plate is moved, on rotation of the cam, to a concentric position wherein a lobe 22 masks the cam depression 23. As long as the cam is rotating-for one or more press strokes-the depression 23 is masked, the valve 14 is held open, and thus the gate 9 is held closed by the cylinder 5 even if the valve 10 is closed and the cylinder 4 thereby cut off from its fluid supply. When the press and the cam 18 come to rest, the plate 19 moves under its own momentum to its eccentric position and the plunger 17 enters the recess 23 to close the valve 14 and open the cylinder 5 to exhaust through the valve 15, so that the rod 8 may move to the right and the gate 9 be opened. If, through a fault, the press begins to operate with the valve 10 closed, the cam 18 causes fluid to be supplied to the cylinder 5, and the rod 8 is moved to the left to close the gate 9.

Patent GB-478442-A (GB)
Title: Improvements in or relating to girders, profile irons and the like
IPC: E04C3/04
Filed: 1936-08-04
Abstract: 478,442. Metal girders. AKTIEBOLAGET NORDISKA ARMATURFABRIKERNA. Aug. 4, 1936, No. 21485. Convention date, Oct. 1, 1935. [Class 20 (ii)] The section of a girder or profile iron has a form which is derived from a standard girder or profile iron of the same type, cross-sectional area, height, and width by omitting from the section a part of the material most remote from the neutral axis X ... X corresponding to the maximum moment of inertia of the section so as to leave ridges 1, and material is added to the section nearer the said axis and so distributed in relation both to this axis, and to the axis Y ... Y corresponding to the minimum moment of inertia that the ratio between the plastic and elastic moduli of the section obtained with respect to the axis X ... X is increased as compared with that of the standard section, while at the same time, the coefficient of form of the section as compared with that of the standard section is reduced. The calculation of the elastic modulus is based, as usual, on the assumption that the yield point of the material has been reached in the outermost layer of the section only, and that the stress at the neutral axis is zero. The calculation of the plastic moment of resistance is based on the assumption that the material of the section has become plastic throughout so that a stress equal to the yield point of the material constantly occurs in all layers of the section from the outermost layer to the neutral axis. The coefficient of form of the section is defined by the expression F/I where F is the cross-sectional area, and I the minimum moment of inertia of the section, and the desired decrease in this coefficient is therefore obtained by so distributing the material in the section as to increase the value of I. The ridges should have a width of about 1/9th to 1/3rd of the width of the profile, and a height of about <1>/15th to <1> /25th of the total height of the profile. The section may be so formed that the ratio between its plastic and elastic moduli, as referred to above, amounts to at least 1.1. Figs. 1, 4, 6, 7 and 8 show respectively the application of the invention to girders of I, channel, Z, angle, and T form, material being omitted to leave ridges 1 and added beneath the flanges as indicated in - dotted lines. The girders shown in Figs. 4 and 6 are modified by the provision of additional ridges 2 which are of the same dimensions as the ridges 1 ; the width of the flanges of such girders is increased somewhat in comparison with the width of the corresponding standard section, but the ridges 2 do not cause any alteration in the cross-sectional area or height of the section.

Abstract: 500,292. Shuttles for circular looms. KINSELLA, E., and HARDY, F. S. Aug. 5, 1937, No. 21621. [Classes 142 (ii) and 142 (iii)] The weft is beaten up by a spring urged large disc 70 which may have a slightly eccentric or an undulating edge and rolls along the fell of the fabric. It may be mounted on a pivot 66 on a lever 67, which is pivoted at 68 to the shuttle 1 and is acted upon by a spring 69, the downward movement of the lever and disc being limited by hooks 16, 17 on the parts 67 and 1 respectively. The spring is carried in a sleeve 31, which can bo adjustably screwed into an extension 24 and be locked in position by a nut 33, a general positioning of the beat-up edge 70 with respect to the fell being obtained. The gap 30 between the headed base of the sleeve and a gauging edge 32 varies according to the beat up pressure, and this may be arranged to be the same for all shuttles, or to differ, so as for example to produce a weft stripe. The height of the edge 70 may also be adjusted by arranging the pivot 66 to carry an eccentric bearing for the disc, or the pivot 68 may be eccentrically mounted in the body casting 1. A shuttle with a guide eye 18, Fig. 1, may be used which beats up the weft bound by a preceding shuttle, or one with a second eye may be used to enable the shuttle to beat up its own weft as well. The disc is shrouded at 72 to prevent entry of warp threads into crevices, and the pivots 66, 68 are formed free from exposed crevices. The shuttle may be provided with flanged rollers engaged by vane wheels, and with a roller mounted on an inclined axis bearing against the inclined rubber face of a stationary annular race. The Provisional Specification refers to Specification 500,293.

Abstract: 1,012,027. Valves. ALLIED THERMAL CORPORATION. June 5, 1962 [June 9, 1961], No. 21621/62. Heading F2V. A fluid flow controller comprises a damper 20, Fig. 3, pivoted at 26 to control flow through the housing 10. A diaphragm 40 is connected at one end to the damper 20 and is wound round a shaft 44 at its opposite end. The inlet to the housing is provided with an apertured plate 15 to maintain a substantially constant pressure. The diaphragm is subjected on opposite sides to the pressure upstream and downstream of the damper and flexes with changes in this pressure difference to rotate the damper. An abutment 46 is provided for the diaphragm so that as it flexes, the effective area is varied to vary the force on the damper to provide a constant flow. The damper is biased by a spring towards the open position. The required flow rate is initially set by rotation of shaft 44. One form of bias is shown in Fig. 2, where a shaft 30, carried by the damper, has a bush 66 with a radial arm 68. A bell-crank lever 50 is rotatable on the shaft 30, the end of one arm being connected by a band 56 to a roller 60 on the shaft 44 while the end of the other arm forms an anchorage for one end 74 of a coil spring 72, whose other end engages the radial arm 68. Thus, rotation of the shaft 44 to rotate the damper also causes rotation of the bell-crank lever 50 through the band 56 and the spring loading 72 on the damper is maintained constant throughout the initial setting. A position indicator 62 may be provided to indicate the setting. In a modification, an involute-shaped spring having one end fixed to shaft 30 and its other end fixed to a link from shaft 44 may be provided. The shaft 30 may be connected to a dashpot to dampen oscillations of the damper.
