Title: Improvements in or relating to a fur sewing machine guide
Inventor: OLDAY FRED LESLIE
IPC: D05B27/18
Filed: 1954-02-18
Abstract: 746,415. Sewing-machines. OLDAY FUR MACHINE CO., Inc. Feb. 18, 1954, No. 4820/54. Class 112. Overhead sewing-machines.-In a cup-feed machine for sliving together strips 76 of fur, a guide 22, situated adjacent the feed cups 10, 14 for positioning the upper edges of said strips at the desired height in relation to a needle operating horizontally above the cups, has a shoe 58 with flared sides, and a vertical blade 62 mounted centrally on the shoe for free lateral movement thereon ; and a hose 74 is arranged to direct a stream of air downwardly adjacent the leading end of the guide. The blade is slotted at 66 to fit over the flared leading-end of the shoe, a wire separating-guide 70 projects forwardly from said leading end, and the trailing end 60 of the shoe is of channel shape. The stream of air, which is directed just forwardly of the wire guide, serves to cause a parting of the fur away from the top edges of the strips 76 as the latter are advanced with the fur sides together, this function being assisted by the wire guide. Cup 10 is directly driven, while cup 14, which is carried by an extensible arm 12, is freely rotatable and is spring biased towards cup 10. Guide 22 and hose 74 are both carried by a lever 26. The latter is pivoted at 30 to a frame 32 secured to arm 12, and has an arm 28 adapted to abut a stop 38, adjustably screwed into frame 32, when guide 22 is in the operating position. A lever 46 is pivoted on a bracket 48 secured to frame 32, and carries a cam 50 adapted to coact with lever 26, against the bias of a spring 40, for depressing guide 22 into operating position, when lever 46 is lowered by a link 52 attached to a pedal. A cam 54, carried by lever 46, is arranged to abut a stop 56, adjustably screwed into a fixed plate 36, when arm 28 and stop 38 abut. Extension of arm 12, for separating cup 14 from cup 10 to accommodate thicker material, serves to raise lever 46 by coaction of cam 54 and stop 56, thereby raising the operative position of guide 22 to increase the distance of the seam from the top edges of the strips 76. In a modification, the wire guide 70 is omitted and hose 74 is arranged to discharge vertically downwards over blade 62.

Title: Improvements relating to electric circuits embodying a heating element
Inventor: MIDDLETON CHARLES DENIS
IPC: G05D23/275
Filed: 1959-02-16
Abstract: 901,733. Control systems for heating resistors. JACKSON INDUSTRIES Ltd. Jan. 13, 1960 [Feb. 16, 1959], No. 5320/59. Class 38 (4). A heating element, e.g. a boiling-plate 2, is connected by a wire 7 in series with an adjustable energy regulator 1 which embodies a heater coil 3 for a bi-metallic element 4 carrying a contact 5 associated with a contact 6. A switch 9 so linked with the regulator control that it can only be closed when the regulator is set to give maximum input and a thermostatic switch 10 incorporated in the plate 2 are connected in series with each other and in parallel with the regulator 1. In operation, when it is desired to heat the boiling-plate rapidly, the regulator 1 is at maximum setting, the contacts 5, 6 and the switches 9, 10 are closed, and the plate is subjected to maximum input. The operating current is split between the wires 7 and 8 and it is arranged that the magnitude of the current passing through the heater coil 3 is insufficient to operate the regulator. The plate 2 thus heats up to a temperature determined by the thermostatic switch 10. When the switch 10 opens, full current passes through the heater coil 3, causing the regulator to operate to give a safe predetermined mean input. If the regulator is subsequently regulated to give a low mean input, the switch 9 is automatically opened so that the switch 10 has no effect should it close at a lower temperature.

Title: Hydraulically operated clutch mechanism
Inventor: SNOY JOSEPH B
IPC: F16H61/02
Filed: 1961-02-13
Abstract: 957,912. Change-speed and clutch control. TWIN DISC CLUTCH CO. Feb. 13, 1961, No. 5327/61. Headings F2C, F2D and F2L. In a pair of hydraulic multi-disc clutches 14, 15 for driving the pinions 17, 19 of a changespeed or reverse gear, a continuous flow of low pressure liquid is maintained through the double actuator chambers 31, 35 and 32, 36 through passages 46, 45 when the clutches are disengaged, the clutches being engaged selectively by supplying high pressure liquid to either actuator through passages 49, 50 or 61, 62. As shown a pump 90 supplies the high pressure liquid to a pipe 91 from which it may be fed by a selector valve 92 to either of two feed pipes 87, 88 connected to passages 49, 61, respectively, the low pressure liquid being fed to pipes 94, 99 connected to passage 46 after exhausting from a torque converter 11. The low pressure liquid fed to passage 45 passes through metering passages in a central fixed reaction member 24 and opens valve discs 58, 68 to allow the liquid to flow through passages 50, 49 and 62, 61 to pipes 87, 88 and exhaust. To engage clutch 15 selector valve 92 is moved to the left to feed the high pressure liquid through pipes 91, 87 and passages 49, 50 to chamber 36 thereby moving the piston assembly 29, 30 to the right against release springs 40. Liquid passes through the metering passages in reaction member 24 into chamber 32, valves 58, 68 remaining open. As the volume of chamber 32 increases the liquid supply thereto is derived chiefly from the low pressure pipe 99 thereby securing rapid clutch engagement. When the clutch is engaged the pressure rise in chamber 32 closes valve 68 and the pressure then rises to its maximum engaging value, chamber 31 having remained connected to exhaust. Upon centring valve 92 to release clutch 15, chamber 32 is reconnected to exhaust and the low pressure liquid flow restored, valve 68 reopened, and flow to both chambers 31, 32 commenced to re-centre piston assembly 29, 30. For engagement of clutch 14 valve 92 is moved to the right, to connect pipes 91, 88 and passages 61, 62 to chamber 31 and thus move piston assembly 29, 30 to the left and close valve 58.

Abstract: 462,896. Shock-absorbers. LESLIE, I. A. Aug. 12, 1935, No. 5382/37. Divided out of 462,747. [Class 108 (iii)] The resistance of a vehicle frictional shock - absorber is increased automatically on a sudden change of vehicle momentum by a mass which is displaced by its inertia in a direction corresponding to the direction of travel of the vehicle when the change of momentum occurs. As shown, the shockabsorber comprises a divided drum member 0<1> integral with an operating arm O and pressed by springs O<3> into frictional engagement with an interior drum member P freely mounted on a projection P<2> rigid with a member P<3> bolted to the chassis frame p<4>. Friction surfaces P<5> are arranged between the members P, P<3> and a spring- pressed washer p<6> carried by the projection P<2>, and a friction surface P<1> between the drum members 0<1>, P, the surfaces P<5> being loaded by the washer P<6> to a lesser extent than is the surface P<1> by the springs 0<3>. A pendulum R<1> is normally held in the position shown in Fig. 1 by a light spring R<2>, the pivoted end of the pendulum being formed as a cam-shaped boss R<3> having an internal clearance above and below the pivot pin R. The boss lies between the drum member P and a cam surface R<4> on the member P<3>. Normally, on movement of the arm 0, the drum members 0<1>, P move as a unit, the damping being provided by the more lightly loaded surfaces P<5>. On sudden braking movement, the pendulum R<1> swings to the right, Fig. 1, displacing the boss R<3> around the pin R and clamping the drum P to member P<3>. Movement between the chassis-frame and arm 0 is thereafter resisted by the heavily loaded friction surface P<1>. The Provisional Specification describes also a hydraulic shockabsorber having a liquid-conduit controlled by a valve having an extension normally in contact with the arm of a pendulum, movement of which forces the valve to restrict the conduit and stiffen the shock-absorber.
