Title: Improvements in or relating to sheet feeding mechanisms for duplicating machines
IPC: B65H1/18
Filed: 1959-01-02
Abstract: 859,973. Feeding sheets. OLIVETTI & CIE S.p.A. ING. C. Jan. 2, 1959 [Jan. 8, 1958], No. 212/59. Class 100(1) In a duplicating machine having an automatic sheet feeding apparatus wherein the sheet pile tray 8 is urged upwardly by spring means, and a cyclically operable bail 20 arrests the sheet pile 7 so that the top sheet is always at a predetermined level, the tray 8 is normally locked by a locking member which is cyclically operable to unlock the tray and allow it to be moved upwardly towards the bail 20. The master sheet drum 3, impression roller 5, and sheetseparating rollers 6 are driven from a main shaft 4, and a cam 15 on the shaft 4 rocks a bell-crank lever 18 which carries the bail 20. The pile tray 8 is slotted at one end which is engaged by a pin 51 on a bell-crank lever 10 which is urged about a fixed pivot 50 by a spring 9. A second bell-crank lever 11 is pivoted on the lever 10 and has a pin 52 at one end engaging a slot in the tray 8, and a pin 12 at the other end engaging a slot 13 in the machine frame 14. The arms, pins and slots are arranged and proportioned so that the tray 8 is kept horizontal during up and down movements. Normally, the upward movement of the tray 8 is locked by a spiral-shaped cam 22 which engages the pin 12. The cam 22 is secured on a fixed shaft 23, and is urged counterclockwise about the shaft by a strap 25 and spring 26 to balance the tray 8 against the action of the spring 9. A lever 27, urged downwardly by a spring 43 to engage a pin 44 on a manually-operable crank 45, is pivoted on the shaft 23. A coil spring 29 engages hubs on both the lever 27 and cam 22, one end of the spring being anchored in an extension of the lever 27, and the other end abuts a fixed stop 34. A cam 42 on the shaft 4 is adapted to rock a lever 38 so that a pin 37 engages an extension 36 of the lever 27 to rock the latter clockwise about the shaft 23: when this occurs, the coil spring 29 is wound up to cause the cam 22 to rotate with the lever 27 against the action of the spring 26. Thus, the edge of the cam 22 retracts from the pin 12, and the tray 8 is raised by the spring 9 until the top sheet of the pile 7 engages the bail 20, which is now in the lower registering position. The cam 42 now releases the lever 27, the spring 26 rocks the cam 22 until the pin 12 is engaged, and the bail 20 is raised to allow the top sheet to be fed by the rollers 6. The manually-operable crank 45 enables the lever 27 to be rocked to allow the tray 8 to be raised and adjusted when a new sheet pile is placed on the tray 8. The cam 22 has a projection 48 adapted to operate a means for stopping the machine when the sheet pile is nearly exhausted.

[Class 130] [Also in Group I] A cutting machine of the type having a rotating head furnished with one or more knife blades is furnished with means for feeding the blades forward to compensate for wear &c. comprising a rod passing through the hollow shaft carrying the head and mounted eccentric to the axis thereof, such rod being adapted to be moved longitudinally to actuate the knife feeding device. A cutter head 14 fixed to one end of a hollow shaft 8 driven through worm gearing 12, 13, carries a number of blades 15 each of which is mounted between a back plate 16 fixed to the head and a spring clamping-plate 17. Each knife is fed forward by a half-nut 19 engaged by a feed screw 18 carrying a worm wheel 23 rotated by a worm 24 on a spindle 25. The spindle carries a ratchet wheel by a strong friction clamp, this wheel being adapted to be actuated by a pawl 29 on a lever 30 having a tail 35 engaged by the end of a rod 36, carried in bearings 37, 38 secured to the shaft 8. A collar 40 with a cam face and a projecting arm 41 is secured to the rear end of the shaft, the cam face being held against a corresponding cam surface 39 on the bearing 37 by a spring 43 at the forward end of the rod. As the shaft rotates the arm 41 engages with an abutment 42 projecting from the main frame, thus rocking the rod 36 and causing it to move longitudinally due to the action of the cam 39 ; the longitudinal movement actuates the lever 30 and the pawl 29, thus causing the knife to be fed forward. The rod is returned to its original position by springs or other devices. The abutment may be movable and thrown into engaging position at desired intervals by a cam which may be driven through changespeed gear. A handle 154 may be attached to the rod 36, which can then be rotated by hand to feed the knife forward while the head is stationary. In a modification, instead of each knife being moved by its own rod, one rod may be mounted in bearings on the main frame and arranged to move axially to engage each lever tail in succession. In a further modification a single rod is mounted eccentrically in the hollow shaft and is engaged at the desired intervals to actuate the pawl levers by a crown cam at the rear end of the shaft ; the crown cam may be carried on a lever that may be oscillated at a desired rate by a cam to vary the periodicity of the operation or that may be swung into engaging position by a hand-actuated device. A cylindrical cam may replace the crown cam. To set the knives independently of each other the end of each shaft 25 is provided with a knurled head by which it may be turned, the friction clutch connection to the ratchet wheel 24 slipping. Specification 365,997, [Group I], is referred to.

[Also in Group XXI] In a pneumatically operated cable tool drill of the type in which the crown sheave 21 is slidably mounted in a mast 16, it being positioned on a piston 29 of a piston-cylinder assembly 27 secured to said mast, the inlet and exhaust ports 32, 33 to the cylinder are controlled electrically by solenoids, the ports being open when current is not passing through the solenoids. The sequence of operations of the ports is regulated by a commutator assembly positioned on the mast and rotated by a chaindriven worm gearing and shaft 38-42, which transmits motion of the piston-mounted sheave to the commutator. The circuits are so arranged that, before the end of the down stroke, the exhaust port 33 is closed so that a cushioning effect occurs in the cylinder and then the inlet port 32 opens, driving the piston upwards, it being shut before the completion of the upstroke, and the exhaust port is opened. Should the piston pass below the inlet port on the downward stroke, then that port is closed. The ports may be so arranged as to open when the current is passing through the solenoids.

Abstract: 824,975. Ratchet clutches. NAPIER & SON Ltd., D. Dec. 23, 1957 [Jan. 9, 1957], No. 905/57. Class 80 (2). Clutch dogs 13, 17 on a driving member 10 and on an intermediate sleeve 16 carried by a quick pitch thread 15 upon a driven sleeve 11, are engaged when relative rotation between the driving and driven members acts through a friction coupling 40 . . . 42 and a flanged sleeve 26 to screw the sleeve 16 along its associated thread, a sleeve 43 carried by the driving member 10 having helical splines &c. of opposite hand to the quick pitch thread, engaged by outer rings 42 of the friction coupling so that the friction coupling itself moves axially and assists engagement of the clutch dogs. The friction coupling comprises friction rings 40, 41 biased to engage each other by a spring 33 mounted between inner and outer connecting sleeves 25, 30. The outer sleeve 25 is integral with the flange 26, which has an externally toothed ring 27 engaging splines 28 of limited length carried by the internally threaded intermediate sleeve 16. Relative rotation between the driving and driven members 10, 11 to disengage the dogs 13, 17 transmits torque through the friction coupling 40 . . . 42 to the intermediate sleeve 16 so that a locating ring 29 at the end of the splines 28 will be engaged by the teeth 27. The intermediate sleeve 16 then tends to pull the outer connecting sleeve 25 against the bias of the spring 33 and eases the spring force engaging the friction rings 40, 41. Thus the drag transmitted between the driving members 10, 11 through the friction coupling 40 . . . 42 is reduced. When the driving and driven members 10, 11 tend to turn relatively to each other in such a direction as to engage the clutch dogs 13, 17, the friction drag imparted to the inner and outer connecting sleeves 25, 30 will be supplemented by an axial pull caused by the helical splines &c. connecting the rings 42 and the sleeve 43. This axial pull is imparted to the intermediate sleeve 16 through the clutch teeth 27 and the locating ring 29. Any tendency for the sleeve 16 to remain stuck in its disengaged position is thus overcome. A manually operated control ring 19 may be moved to the left of the Figure to disengage the dogs 13, 17 or to prevent them from engaging.
