Abstract: 1,072,999. Gear cutting. GLEASON WORKS. Nov. 1, 1965 [Nov. 27, 1964], No. 46081/65. Headings B3B and B3K. A chamfering machine comprises a cutter support 26 pivoted to a frame for oscillation about an axis 7 transverse to the axis of a work spindle 3, a milling cutter C-1, C-2 rotatable on an axis 31 parallel to the oscillation axis, and means 53 for indexing the work spindle while the milling cutter is in a withdrawn position. The device may be an adjunct to a gear-cutting machine. The cutter support is oscillated by a crank 12 through a connection 14, 16 which allows the arc of swing to be adjusted. Each cutter is mounted on a shaft 31, 32 carried by a bracket adjustable angularly on a circular plate 22. The cutters are driven by cogged belts 35, 40. Each cutter is adjusted axially by spacers 49 and nuts 51, 52. To set the work at the correct height, a nosepiece having a shank and a collar 47 is fitted to the spindle 3 by screws 48. The work is indexed, while the cutters are withdrawn, by a face cam 71, an adjustable follower lever 68, a rack 67, a pawl-carrying plate 58 and an index plate 53. The machine is driven by a single motor 18 which is stopped when a button 85 on the workspindle 3 actuates a switch 83 to denote 360 degrees indexing of the work and the arm 14 actuates a switch 84 when the cutters are in withdrawn position.

Filed: 1972-10-10
Abstract: 1380490 Feeding sheets DIDDE-GLASER Inc 10 Oct 1972 [8 Nov 1971] 46620/72 Heading B8R Apparatus for separating sheets in turn from the top of a pile 14, Figs. 1 and 4, comprises a pick-up assembly 10 and a hold-down structure 30. The assembly 10 comprises a tubular vacuum manifold 12, attached to which by brackets 18 and spaced therealong are a plurality of sucker units 16. Each unit 16 comprises a vacuum tube 20 connected to the manifold by a hose 22, and a hollow cylinder 24 carrying a sucker head and slidably mounted on the tube 20, being urged downwards by a spring 26 into the position shown in full lines in Fig. 4. When the sucker head contacts a sheet, the vacuum force raises the cylinder to the broken line position shown in Fig. 4. The structure 30 comprises a plurality of fingers 32, each finger being aligned with a unit 16 in a plane perpendicular to the manifold 12. Each finger comprises a rigid core 34 and a projecting resilient plastic covering tube 37, and all the fingers are connected to a common bar 36 below and parallel to the manifold. The bar is secured in vertically adjustable relationship to the manifold by two brackets 38. Each bracket comprises members 40, 42 secured to the bar and each engaging one side of the manifold, the member 40 having a horizontal leg through which is threaded an adjusting screw 44 abutting the top of the manifold, the bar being urged away from the manifold by a spring 48, whereby the relative vertical position of the lower ends of the fingers 32 and cylinders 24 is adjustable according to the thickness and other characteristics of the sheets. In operation, the entire apparatus 10, 30 is lowered as a unit until the fingers and sucker heads engage the top of the pile, whereupon retraction of the cylinders 24 results in raising of a marginal edge of the top sheet 14a, the adjacent area of the sheet being held stationary by the fingers so that the sheet flexes about a line parallel to the manifold, and inadvertent separation of two sheets together is thereby discouraged. The apparatus is then raised as a whole to completely separate the top sheet from the pile.

A machine for applying a wire around a parcel comprises a frame 3 guiding the wire which is fed through rollers 7, 8, the roller 7 being driven by a reversible pneumatic motor, a tiltable wire clamp 9 receiving the leading end of the wire after it has passed around frame 3, a further clamp 6 tensions the wire about the parcel, the machine having an electric and pneumatic control system which includes a master valve energized from a main switch to control the flow of compressed air to valves and jacks for operating the machine. In operation, the end of the wire, after passing around the frame, tilts clamp 9 to operate valve 12 causing the clamp to close, a switch 10 is also closed. A starter switch is then pressed to start the tying operation. Firstly, a set of rollers on table 2 on which the parcel moves are retracted; small cylinders 4 on the frame open the guiding track to release the wire and clamp 9 is released; the pneumatic motor is reversed to withdraw the wire. Clamp 9 tilts in the opposite direction against a leaf spring to operate switch 10 to close the clamp 6 which is moved by jack 32 to tension the wire. Clamp 9 is now closed and a block 13 having a pinion 21 with a slot, is moved by cylinder 18 to place the slot over the wire ends, a switch 19 operated by block 13 releases clamp 6 which returns to its normal position. Block 13 closes a switch 20 causing a cylinder 25 to move a rack 23 to rotate pinion 21 through gear 22 to twist the wire ends. The rack closes a switch 27 causing the small cylinders 4 to be exhausted and allowing springs to close the wire track. On return movement of rack 23, cutter 29 severs the wire and a cam 30 releases a valve 31 to cause the opening of clamp 9 and the withdrawal of block 13 so closing switch 19 and opening switch 20 to raise the table rollers and operate a valve to allow the motor to feed wire into the machine. The main switch can be operated to stop or start the machine. Details of the control system are given in Figs. 3, 3a, 3b (not shown).
