Patent GB-361602-A (GB)
Title: Improvements in stop motions suitable for textile machinery
IPC: D01H13/16
Filed: 1930-11-18
Abstract: 361,602. Electric stop motions for textile machines. SCOTT, W. J., 78, Collins Street, Woonsocket, Rhode Island, U.S.A. Nov. 18, 1930, No. 34671. [Class 120 (ii).] In an electricallv controlled stop motion, for use in textile machines and of the kind comprising a member urged to stop the machinery but locked in an inoperative position by the engagement of a latch pivotally mounted on the member with a catch which is disengaged by the completion of the circuit of an electromagnet, the catch member is positioned below the armature plate of the electromagnet. The electromagnets are enclosed in a casing 25 insulated by material 28 from a holder 27. An armature plate 32 is pivotally mounted by a pin 33 beneath the magnets and has notches 36 to engage arms 37 pivoted in the casing 25 by a pin 38. A catch member 39 with a base 40 is pivotally mounted below the armature plate by a pin 42. Trunnions 46 on the catch member normally engage in recesses 47 in the arms 37. A spring 43 tends to force the catch member 39 downwards. When the switch 48 is closed the circuit is completed, the armature plate 32 is attracted upwardly and the arms 37 swing rearwardly, allowing the latch member 22 to move past the catch member 39 against the action of the spring 43, so that the spring 18 can move the member 16, and hence by means of the stop 15, rod 14, and belt fork 13, move the belt from the fast pulley 10 to the idler 11. The disengagement of the latch and catch members breaks the circuit and the action of the springs 35, 43 then returns the armature plate, arms 37, and catch member to their normal positions. To restart the machine, the switch 48 is opened and the member 16 moved against the action of the spring 18 until the latch and catch members re-engage, the latch member swinging about a pivot against the action of the spring 24 while it is passing the catch member, and returning to its normal position, in which it is retained by a member 23 abutting against the arm 20, when it is past the latch member. The switch 48 may be closed by hand or by any of the methods disclosed in Specifications 302,855, 304,547, 312,694, and 331.993, [all in Class 120 (ii), Spinning, twisting, &c.].

Abstract: 600,443. Packing safety - razor blades. FAIREST, Ltd., M., and DICKINSON, E. V. Dec. 28, 1945, No. 35036. [Class 94(i)] A razor-blade package comprises a blade with at least one locating aperture and a stiff protective sheet wider and longer than the blade and formed with a pair of tongues passing through the aperture or each passing through an aperture so as to hold the blade temporarily to the sheet, the tongues facing away from each other towards the ends of the sheet, and the sheet being sufficiently stiff to be bowed away from the blade by pressure on its ends, so as to withdraw the tongues from overlapping engagement with the blade and release the blade from the sheet. A standard three-holed double-edged razor blade 31, Fig. 3, is secured to a longer and wider protective sheet 32 of stiff paper or card, having tongues 33. The tongues may be pushed up by pins, the blade lowered on to the sheet so that the tongues pass through the end holes of the blade, and the pins removed to allow the tongues to spring down on to the upper surface of the blade to locate it securely on the sheet. The blade can be released for placing on a razor by bowing the sheet by pressing in the ends. The package may be enclosed in an outer wrapper of material such as waxed paper. The wrapper folds may be secured by adhesive or may be self-adhesive and secured with or without heat. The wrapper may be folded round a plurality of sheets and blades to form a multiple package. A method of forming packages according to the invention comprises assembling on a support 68, Fig. 13, sheets 64 and blades 66 fed thereto in timed relationship from stacks 65, 67, and feeding the assembled blades and sheets in spaced longitudinal relationship on to an envelope strip 69 fed from a roll 70 between folding scrolls as 73, Fig. 16, which curl its edges over the edges of the assembled blades and sheets. The envelope 80 thus formed is transversely folded between each sheet, as by a pressing device comprising anvils 81, Fig. 21, and creasing members 82 on an oscillating arm 83, and a zig-zag pack is formed, from which individual blades may be removed by tearing or cutting. Perforations may be provided to facilitate removal. Alternatively the sheets may be spaced apart so that the envelope 80 may be severed into individual packages, the ends of each of which may be folded over. The packages described are designed to protect the cutting edges of the blades from contact with the wrapper.

A power transmission with primary and secondary power trains in parallel includes a slipping clutch in the primary train to regulate the distribution of power between the two trains. In the arrangement shown for an earth-moving vehicle the main input shaft 10<SP>1</SP> drives the main transmission 1011, 20<SP>11</SP>, 30<SP>11</SP> . . . through a hydrodynamic retarder 17<SP>1</SP>, gears 20<SP>1</SP>, 21<SP>1</SP>, shaft 22<SP>1</SP>, slipping disc clutch 53 and gears 54, 55, 46<SP>11</SP>, and an hydraulic transmission 50c, 50d for the implement 50e through gears 20<SP>1</SP>, 50a. Clutch construction and control.-The clutch consists of sets of discs 74, 75 engageable by an hydraulically operated annular piston 58, the liquid supply being under the joint control of a pneumatic selector valve 56 and a centrifugal valve 57. Oil from the lubricating system may pass to the clutch discs through passages 73, 68 for cooling purposes. When the vehicle is moving without the earth implement in use the air supply to valve 56 is cut off so that spool 56b is moved downwards by a loading spring 56c to allow unrestricted entry of pressure liquid from inlet port 63 to passage 57d and chamber 57e for full engagement of clutch 57. With the implement in use air is supplied to chamber 56d to raise spool 56b against spring 56c, as shown, so that pressure liquid for clutch piston 58 passes from port 63 to passage 57d through a metering orifice 56e, reducing the volume of flow. The centrifugal valve 57 includes a spool 57b radially movable under the joint control of a loading spring 57e and pressurized liquid acting in chamber 57g on the spool end, the latter having lands 57j, 57k controlling a bleed port 57m. Operation (Fig. 4).-When a load is imposed on the implement the regulating action of valve 57 causes the clutch pressure to drop rapidly for a relatively small reduction in engine speed as shown by the parabola B, with the clutch slipping at a selected point P 1 . With increasing load the speed falls until at point P 2  the metering action of valve land 57j ceases, the orifice 57m then maintaining a low clutch pressure until at point P 3  land 57k cuts off orifice 57m to restrict the flow through orifice 56e and cause a rapid pressure build up in the clutch until the maximum value is reached at P 4 .
