Filed: 1949-03-24
Abstract: 658,551. Shearing. PEAT, J. T. March 24, 1949, No. 8061. Convention date, April 9, 1948. [Class 83 (iv)] In a machine for cutting printers' slugs and rules, two cutting edges 17, 18 at right angles to one another on a vertically reciprocating blade 16 co-operate with edges 20, 21 on a fixed blade 19 and adjustable length gauging stops are operated on both sides of the blades and a corner gauge stop in front of the blades. The moving blade holder 10 is reciprocated in runways 9 on a vertical frame 8 by a hand lever 15 which rotates a plate attached to its fulcrum pin 14 having a cam slot in which a following roller on a pin 47 in the top of the blade holder is located. The gauge stop 22 for trimming slugs to length is slidable in grooves 23 on an arm 24 and is attached to a rack bar 25 which slides in a block 26 on the arm 24, the bar being locked in adjusted position by a spring-loaded plunger. The slug may be held against guide faces 31, 32 of a strip 33 on the arm 24 to ensure square cutting. In removing part of the type surface to avoid smudging, the slug is placed against the edge 34 of the corner gauge stop 35 so that a corner piece is removed along an L-shaped shearing line. Lead rules may be cut by using the stop 22 as above but a rule gauge stop 36 with anvil portions 37a is also provided, the stop being slidable along a bar 38 fixed to the machine base and steadied by a rack bar 39 attached thereto and slidable in a hole in the machine base, and engaged for locking by a spring-loaded plunger 41. - Further fine adjustment is obtained by a vernier nut within the stop 36 which engages a screwed portion on the end of the rack bar 39. Support for the work is obtained by a strip 43 attached by an arm to the machine base so that it may be swung clear when not required. Guide faces 46 may be formed on the strip 43 in line with the guide faces 31, 32.

Abstract: 718,453. Endless-track vehicle driving-gear. HARNISCHFEGER CORPORATION. April 1, 1952. No. 8297/52. Classes 79(2), 79(3) and 79(5) [Also in Group XXXIV] In an endless-track vehicle in which the tracks are driven by a reversible electric motor, one of the tracks is permanently connected to the motor and the other track is connected thereto through a clutch, the clutch being operable when disconnecting the drive to lock the track. As shown the invention is applied to a crane supported by endless tracks 1. 2 mounted on a frame 3, the crane body 10 carrying a jib 13 being rotatab1y mcunted on the frame 3 by means of rollers 7 and a hollow pin 12 engaging a sleeve 11 on the frame and the body being rotated relative to the frame by means of an electrically driven pinion 15 on the body engaging a ring gear 6 on the frame. Mounted on the body 10 is the reversible electric traction motor 55 connected by gearing 48, 50.... 54 to a vertical shaft 45 which is connected by level gearing 43, 44 to a shaft 26 mounted in the frame 3. The shaft 26 carrier a bevel gear 25 meshing with a bevel gear 24 carried at one end of a shaft 21, whose other end is gear connected to a shaft carrying sprockets 16 by means the track 1 is driven. The other track 2 is driven by sprockets 17 on a shaft 27 geared to a shaft 32 which splinedly carries at 35 a clutch sleeve 36. The sleeve 36 can either be engaged with the gear 24, so that the shaft 26 can drive the track 2, or with the frame 3, so that the track 2 is locked. The sleeve 36 is reciprocated by means of pistons 90, 91 in cylinders 92, 93 which are connected by conduits 96, 101 to parts 97, 102 in a valve 98. Pressure liquid is supplied to the valve 98 through a conduit 100 by a gear pump 60 driven by a three phase squirrel cage motor 65, the pump and motor being mounted in the frame, and the pump drawing liquid from a sump 64 to which liquid is exhausted from the valve 98 through a conduit 106. The valve is controlled by a piston 104 operated by a solenoid 107 against the action of a spring 103, the solenoid being connected to slips rings 110, 69 mounted on the sleeve 11, the body 10 carrying brushes 72, 111 which engage the rings and connect them through a drum type controller 75, when it is in position " B ", to an electrical supply. When the controller 75 is in position "A", the supply is connected through further bushes and rings to the motor 65. The pump 60 also supplies pressure liquid to a cylinder 59 which disengages a brake 56 on the shaft 26, the brake being applied by a spring 58. The strength of the spring 58 is so chosen as to resist the hydraulic pressure in the cylinder 59 until such pressure substantially exceeds that required to cause movement of the pistons 90, 91. U.S.A. Specification 1,833,032 is referred to.

Filed: 1916-06-13
Abstract: 104,439. British Westinghouse Electric & Manufacturing Co., (Westinghouse Electric & Manufacturing Co.). June 13, 1916. Systems for alternating-current motors only.-Two motors of the alternating- current doubly-fed compensated commutator type are operated by connecting each terminal of the cross field winding of each motor to the supply transformer and connecting a terminal of the cross field winding of one motor through the armatures and main field windings of both motors to a terminal of the cross field winding of the other motor. As the cross field windings are wound with twice as many turns as the armature winding the switches 1, 3, 7, 10, will carry each substantially half the working current. The motors are started as repulsion motors and then connected for doubly-fed operation and the voltage impressed on the cross field windings reduced by even steps, and the voltage on the armatures and main field windings increased. The main field windings 17, 20, Fig. 3, may be connected together through the actuating windings of limit switches 40, 41 and disconnecting switches 29, 30. Emergency contact members 42 are provided for the switches 29, 30 by which one of the motors can be connected to one of the transformer taps 3, 7 when the other motor becomes disabled, thereby including the normally inactive portion of the transformer between the taps 3, 7, and thus impressing upon the motor a greater voltage than half the voltage between the switches 1, 10. Limit switches 43, 44 having a higher setting than the switches 40, 41 are included in the leads from the taps 3, 7. Tn a further modification the transformer is divided into two positions 22<1>, 22", Fig. 14, and for the first running positions the sections 34, 35 are disconnected. With one of the motors disabled the other motor can have a variable voltage impressed upon it by means of the sections 34, 35 and the switches 36 - - 41. An additional low-speed running position may be obtained by passing current through the armatures in the reverse direction to that employed in normal operation

Abstract: 415,669. Road signals for controlling traffic. HEUER, J., Grune, Westphalia, Germany. March 21, 1934, No. 8899. Addition to 368,671. [Class 118 (ii).] A double-ended pointer, instead of moving over a divided red and green disc as claimed in the parent Specification, moves over a disc of a single colour, contrasting with the colour of the pointer, the signal colours being shown on the surround of the disc. Instead of a pointer the disc may be provided with a slot shaped similarly to the double-ended pointer and illuminated from behind, the disc being arranged to rotate. Instead of red and green indications on the surround, contrasting colours such as black and white may be provided with an intermediate shade for the amber period. The amber period may be dispensed with, the pointers on the two roads being set to give an all-red period. As shown in Figs. 1 and 2, the light coloured pointer 2<a> rotates over the dark coloured disc 1, the red and green colours being shown on the surround as shown at 5<a> and 3<a> respectively. The apparatus at crossing roads is arranged so that when one pointer, Fig. 1, is in the dotted position, that is, about to leave the green area, that on the crossing road is still on the red area, as shown dotted in Fig. 2. The arm is horizontal for " go " and vertical for " stop " to be in agreement with the usual semaphore-arm code. Instead of the pointer 2<a> being an additional unit, it may be a slot in the disc 1, the disc then being arranged to rotate and to be illuminated from the rear during hours of darkness. Instead of red and green, the colour fields may be light and dark as shown in Fig. 4, the amber fields 4b being yellow or grey. The fields may be illuminated from the rear if desired, and neon type lighting may be employed, the lamps having oxide electrodes and being filled with a mixture of inert gas, such as neon, and metal vapour such as sodium vapour.

Filed: 1973-02-23
Abstract: 1415789 Covering annular cores MONSANTO CO 23 Feb 1973 [24 Feb 1972] 9006/73 Heading B8G [Also in Divisions B3 and B7] A method of forming a cable bead for a pneumatic tyre comprises supporting an annular core 3 and rotating it about its axis of symmetry perpendicular to the plane of the core, feeding strand 1 to the core from a coiled supply 4 while rotating the supply about the annular core, maintaining constant the direction of a diameter of the coiled supply in a plane parallel to the plane of rotation of the supply about the core, and varying during each rotation of the coiled supply the angle which the axis of the coiled supply makes with the plane of rotation of the coiled supply about the core. Apparatus for forming the bead includes a reel carriage assembly, a bead supporting and rotating assembly and a motor drive assembly. A canister 4 of coiled strand is mounted on a rotating platform 5. Grooved guiding rollers 8, 9, rubber faced idler rollers 10-14 and driven rollers 15-19 comprise the bead holding and rotating assembly. The outer rollers 15-19 are mounted on swing arms pivoted about shafts 20-24 using air cylinders 25. Power is supplied via a gear motor 32 which drives a variable speed gear-box 36 serving as a synchronizer by which the ratio of the bead speed to the reel carriage speed can be adjusted as required. Platform 5, which contains a slot 47 for loading the core and unloading the bead, may be rotated in clockwise or counterclockwise direction as desired. A drive sprocket 70 rotates the reel in the opposite direction to the platform and powers bevel gear (61), Fig. 4a (not shown), which drives gear (64) meshing with a shaft (66) on which the supply is mounted. This arrangement maintains the reel in the same orientation with respect to the bead such that a diameter of the reel parallel to the plane of the rotating platform is always parallel to the plane of the core. The core may be rotated using a series of grippers (100), Figs. 5, 6 (not shown), mounted on an endless chain (101) driven by a sprocket (102a) on a shaft (102). The staggered grippers within track plates (107) are held against the bead by spring pressure exerted by a series of springs (110).
