Abstract: 682,747. Angular bending. MEMPHIS METAL MANUFACTURING CO., Ltd. Feb. 19, 1951,No. 4037/51. Class 83 (iv). A machine for flaring the part of a sheet of metal surrounding a circular opening therein, comprises a flaring element having a curved surface inclined up and inwardly towards the axis of the opening and extending below the plane of the sheet so that this is flared upwardly upon rotatory and radial ,movement of said element. A clamping plate 9, counter-balanced by weights 10, is first lifted, the upper bearing 24 of a shaft 12 is raised by a hand-wheel and shaft 27 and rollers 28 are removed. A flat work-sheet 8, Fig. 6, with a central hole H, Fig. 4, is then inserted, edge-wise, beneath the plate 9 and bearing 24 and lowered over the shaft 12 on to a bed plate 7 and to engage the hole H with three rollers 16 carried by slides 20 which are radially movable in slots 18 of a spider 14 keyed to the shaft 12. This can be driven in either direction by a motor 6 on a platform 5. A sleeve 42 is then rotated by tommy bars 45 to rotate frictionally a nut 25 and screw it down the shaft 12 thus moving down a sleeve 23 feathered on the shaft and connected by levers 22 to the slides 20 so that the rollers 16 are moved outwardly to centre the sheet 8. The plate 9 is then lowered and jacks 11, Fig. 1, or other devices are actuated to clamp the sheet 8 to the bed plate 7. The bearing 24 is also lowered to receive the upper end of the shaft 12. Arms 29 carrying the rolls 28 are then applied and secured by rotating bearing caps 54 about vertical pivots to hold pivots 30. The shaft with its spider 14 slides 20 and rolls is then rotated by the motor 6, pressure is applied to removable handles, (not shown), to press the rolls 28 on the upper face of the work. The sleeve 42 is prevented from rotating by the bars 45 and, by reason of a bushing 41 of friction material, tends to prevent the nut 25 from rotating. This causes the nut to screw down and force the rolls 16, outwardly, the inner edge of the sheet being formed to the desired contour. The motor is then reversed and the plate 9 &c. removed to release the work. The frictional pressure of the bushing 41 can be varied by adjusting bolts 43. The vertical position of the work can be varied by removing one or more of the plates 7, 7a. The roll 28 may be replaced by a segmental ball 34, Fig. 11. Fig. 22 shows a modification in which the platform 5 is omitted the means for raising the plate 9 being attached to the ceiling and the motor 6 being mounted on the base 1. An attachment for beading the inner edge of a flare comprises a bracket 35, Figs. 17, 18, secured to the housing of one of the rolls 16 on which a slide 37 is moved vertically by a screw s. The slide carries two arms 36 with beading rolls r. The screw s is intermittently rotated by a pin wheel 38 thereon engaging a fixed abutment 39.

Filed: 1936-02-10
Abstract: 471,969. Multiple fastenings. HARLEY, C. E., and RIPAULTS, Ltd. Feb. 10, 1936, No. 4041. [Class 44] A multiple fastening for a motor-car bonnet is provided by a middle hooklike depressible catch, which engages a stirrup on the frame, having operatively connected therewith locking members to form additional fastenings at the vertical edges of the bonnet panel. For instance, levers 11 are connected to a collar 10 on the stem of the depressible hook 2 and are slotted at 12 to engage fulcrum pins 13 ; the outer ends of the levers engaged inclined lugs 16 on the dashboard and radiator uprights and thereby cause the panel of the bonnet to abut tightly against such lugs. The depressible hook may also be disengaged by rotating the stem 90‹. The collar 10 is so mounted, for instance by a slow helical thread or a bayonet coupling or as shown, as to allow such rotation of the stem but without substantial axial movement of the collar. The stirrup may be of the form comprising a movable cross-bar 7 as described in Specification 468,646. In an alternative construction in which there is provided a hook member forming an extension from a plate adapted to be displaced in a more or less vertical direction such member is connected with locking members to form the additional fastenings. Where the hook member is slidably arranged in a guide and is provided with a slot through which extends the extremity of a spindle connected with a handle member whereby the spindle may be rotated and furnished with an arm to which is connected one limb of a hairpin or loop spring, the other limb of which is connected with a pin on the plate so that the spring operates to constrain the arm to move over its dead centre position and to engage against a stop whereby the spring remains under stress and so retains the hook in its locking position, the hook member may be pivotally connected with rods forming the additional looking elements.

Title: Improvements relating to light-sensitive apparatus
IPC: H05B39/04
Filed: 1932-02-17
Abstract: 402,045. Light-sensitive cells. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Feb. 17, 1932, No. 4761. Void [Abridged as open to inspection under Sect 91 of the Acts, Feb. 18, 1932]. [Class 40 (iii).] A light-sensitive cell 2, 12 is subjected to intermittent light of varying intensity, and is in a circuit which integrates the resultant electric impulses in accordance with the strength of illumination. The casing 3 of the cell is structurally combined with a perforated disc 6, shutter, or mirror for occulting the light. The disc is driven by a synchronous motor or phonic wheel 7, and is so constructed that the bright period is shorter than the dark period, and the time between the consecutive changes is so great that the resistance of the cell reaches its static value. The cell is connected by a cable to an amplifier 11, which operates a relay 20 in response to the illumination of the cell. This relay causes intermittent current to flow through a thermo-contact 23, 24, independent of the external temperature. When the brightness of illumination falls sufficiently, the heating-coil 23 closes the contact, which operates a final relay 26. The operation of the relay 26 is delayed by the necessity of heating the bimetallic strip of the thermocontact, but the release is instantaneous. The delaying device may be mechanical or magnetic.
