Title: Machine tool mechanism for cross feeding in discrete amounts
IPC: B24B47/20
Filed: 1958-12-18
Abstract: 844,209. Grinding. CINCINNATI MILLING MACHINE CO. Dec. 18, 1958 [April 14, 1958], No. 40856/58. Class 60. Mechanism for feeding a worktable in discrete amounts towards a grinding wheel comprises a rotatable shaft 30, Fig. 4, connected with a ratchet wheel 54, a reciprocating pawl 68, Fig. 5, adjacent the ratchet wheel for rotating the latter in a pro-determined direction, a solenoid 72 for causing the reciprocation of the pawl, and a foot-operated switch for energising the solenoid. The workpiece 24, Fig. 1, which may be a milling cutter, is mounted between tail-stocks 21, 22 on a table 20 movable longitudinally on a saddle 19 which is arranged for cross-feed on a base by means of the rotatable shaft 30 in the form of a lead screw. At the end of each longitudinal pass, the work is given an increment of feed by energizing the solenoid 72 through the switch 78, Fig. 1, the pawl 68 being engaged with the teeth 43 of the ratchet wheel 54 when the solenoid is de-energized. The pawl 68 is pivotally mounted on a spring-urged link 66 actuated by the solenoid 72. The amount of feed, as determined by the number of teeth traversed by the pawl between successive engagements with the ratchet-wheel, may be varied by re-setting an adjustable angle bracket 80, Fig. 5, the edge 81 of which may be set to permit the pawl to engage more or fewer teeth at each forward stroke of the member 66. A second bracket 86, projecting from an arm 84 adjustably clamped to the ratchet-wheel 54, may be set to move the pawl 68 from engagement with the wheel after the required amount of material has been removed from the workpiece. The rotation of the ratchet-wheel 54 is transmitted to the lead-screw 30 by doublereduction gears 53, 50, 49, 52, Fig. 4, the latter gear being secured to a shaft 50 which drives the shaft 30 through bevel gears 42, 51. A handwheel 59 is keyed to the end of the shaft 50 to provide for re-setting.

Abstract: 1,082,657. Trays. WOODMET Ltd. July 22, 1966 [Sept. 25, 1965], No. 40896/65. Heading A4A. A tray or other article having a flat surface around the periphery of which is mounted an upstanding rim is characterized in that the rim comprises male and female extruded sections 8 and 6, adapted when interfitted to lock one within the other and formed at the inner sides with flanges 11 and 12 between which the edge of the base sheet 13 can be gripped. The interfitting part 7 of the male section 8 may be fitted with barb-like projections 10 so that it may bite into the female section 6, which is preferably made of softer material. The base-gripping flange 11 of the female section 6 can be rebated to provide a locating shoulder 16 for the base sheet 13 and the base-gripping flange 12 of the male section 8 can be grooved to accommodate the said shoulder 16. Both rim sections may be constructed of two U-shaped parts.

Abstract: 1,080,471. Seaming. FORD MOTOR CO. Ltd. Oct. 9, 1964 [Oct. 17, 1963], No. 40987/63. Heading B3J. A machine for bending over the edge of a metal sheet, particularly for clinching together the inner and outer panels 11, 9 of a vehicle door, comprises an anvil 1 for supporting the sheet and a tool 25 connected to parts 13, 24 arranged to first pivot the tool from an inoperative position to a position above the edge to be bent, and then to move vertically downwards to cause the tool to bend the edge back towards the main body of the sheet. The edge of the outer panel 9 is initially bent inwardly at 45 degrees, Fig. 3 (not shown), and the inner sheet 11 is pre-assembled within this edge. The assembled panels are laid on the anvil 1 and positioned by fingers 39 operated by pneumatic devices 41. Clamping pads 47 on a pneumatically actuated clamp 45 then press on the inner panel 11 whilst the tools 25 are first pivoted inwardly and then moved downwardly to clinch over the edge of the outer panel. Tools 25 consist of steel bars secured to beams 24 carried by arms 13 having cam surfaces such as 27, 29 engaging a roller 33 mounted on the machine base 3. The arms 13 are pivoted at 17 to hydraulic actuators 37 and are connected by links 19 to torsion bars 21. The cam surfaces thus produce the inward and then the downward movement of the tools when the actuators are energized. The bending over of the outer panel edge to 45 degrees and the final clinching operation may be performed in the same or separate machines. An ejector 55 removes the door from the anvil.

Title: Binary counter

Filed: 1964-10-12
Abstract: 1,057,770. Electric digital calculators. GENERAL PRECISION Inc. Oct. 12, 1964, No. 41505/64. Heading G4A. A number is entered into a dynamic store such as a magnetic drum and counted down at successive rotations of the drum until a zero registration produces an output pulse. When read-in flip-flop 38 is set the number to be entered is applied in serial real and complemental binary form over leads N, N, respectively, i.e. through AND gates 28, 26. During each subsequent circulation the bits in elements t0-ty are read to energize lead Rc or Rc and AND gate 18 or 22, respectively. Bit timing signal t0 sets control flip-flop 32 at the beginning of each circulation to enable AND gates 22, 26 whereby input or recirculated information is inverted before application to write amplifier. This condition continues until 1 is detected when inverter 19, delay line 20 and AND gate 36 are operated to restore flip-flop 32. Gates 18, 28 are then opened and 22, 26 closed so that the rest of the information is recorded in real form. The detection of zero opens AND gate 34 to issue an output pulse. If inverter 19 is omitted the apparatus counts up and the input must be complemented.

Abstract: 1,241,604. Doubly refracting prisms. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Sept. 3, 1968 [Sept. 5, 1967], No.41859/68. Heading G2J. A combination of an even number of equal angled doubly refracting sequentially arranged prisms P1, P2, P3, P4 is characterized in that for each face at an angle to the axis of the combination there is provided another face at an equal and opposite angle to this axis, the refracting angles γ/4 being inverted alternately relative to each other with respect to the said optic axis, a previously polarized light ray traversing the prisms alternately as an ordinary and an extraordinary ray. This arrangement in a digital light deflection device serves to reduce the angular aberration to which a simple prism would give rise. The optic axes 01, 02, 03, 04 of the individual prisms are at right angles to the axis of the combination and alternately at right angles and parallel to the refracting edges of the prisms. If the component prisms are not in optical contact the free space f between the prisms is filled with an isotropic homogeneous material, the refractive index of which is preferably the arithmetic average of the refractive indices of the doubly refracting material.

An end of train, detector comprises a coil 1 suspended from the rear automatic coupling 2 of each train vehicle 3 the circuit of which is completed so as to co-operate in passing with a pair of track coils and generate in these coils an end of train signal only when a further vehicle is not connected to the rear of the vehicle 3. Each vehicle in the train is provided with a coil 1 but on being coupled to the next vehicle in the rear the coupling hook 6 moves a flap 5 associated with the coil to the vertical position and opens a microswitch in the coil circuit hence only the coil of the last vehicle is active. The flap 5 is retained in the vertical position by toggle or locking means until returned manually to the position shown. Where the train is vacuum or air braked the flap 5 may be arranged to operate a valve in the train pipe to vent the pipe if a further unauthorized vehicle is coupled to the scheduled last vehicle of the train.
