The plates 18, 20 are secured to a slide 24 connected to a link m and movable in a slideway 1 on the framing i, in which slideway the casing 3 is also slidable. The slide operates, through a link 34, a pawl and ratchet 38, 39 which operate wire-feed rollers 41, 44. The roller 44 is carried by a pivoted lever 45 which can be moved by a lever 49 to disengage the feed rollers. Wire for the staples is fed from the rollers through a guide 16 across the anvil 7 and up to an adjustable stop 6. It passes beneath a pin 17 which retains it on the anvil. A pusher 18 slidable over the anvil 7 is connected to a pivoted lever 13 formed with a lug extending in the path of a lug 27 on the plate 18. A spring 31 urges the lever 13 inwardly. A spring 51 acts as a brake on the pin on which the roller 41 is mounted. In operation, when the slide is moved downwardly, the casing 3 first descends and engages the work. The plates 18, 20 then descend. The lug 27 moves the lever 13 outwardly, the plate 18 cuts off and shapes a staple, and the driver 21 inserts a staple which has been made and moved into the driver passage in a previous operation of the machine. When the slide moves upwardly again, the spring 31 moves the lever 13 inwardly, so that the pusher 8 moves the shaped staple into the driver passage. At the same time, the link 34 operates the feed rollers to feed a fresh staple length across the anvil.

Filed: 1945-04-04
Abstract: 591,879. Loose-leaf binders. GILBERT & SONS, Ltd., A., and GILBERT, A. April 4, 1945, No. 8286. [Class 146 (i)] A loose-leaf binder, or a cover or clamping bar for such a binder, includes clamping or locking means comprising relatively rotatable parts one of which is captively associated with an operating member which is stowable in the edge of the cover or clamping bar, As applied to a thong binder, Fig. 1, wherein the thongs 5, 6 pass over rollers in the binding bars and are attached to a bar 10 in the cover carrying a nut 11 mounted on a screw 13 which is rotatable but is held against axial movement by collars 18, 19 engaging an enlarged part 17 of the screw 13, the screw 13 has an extension 20 carrying a pin 23 which works in a slot 24 of a sleeve 22, Fig 3, a spring ring 25 in an eccentric slot 26 of the sleeve 22 providing friction between the sleeve and the extension 20. A headed pin 26a is secured to the sleeve 22 by a cross-pin 28 and a knob 29 having a boss 32 which is formed with the teeth 33 to engage recesses 34 in the sleeve 22 to form a clutch, is mounted on the pin 26a and urged towards the sleeve 22 by a spring 36. A recess 30 is provided in the edge of the cover to receive the knob 29 when not in use. To operate the binder the knob 29 is withdrawn from the recess 30, the spring 36 holding the clutch members 33, 34 together and the pin 23 sliding relatively to the slot 24; the knob is then rotated to move the bar 10 as far as necessary, and pushed back into the recess 30. If the axis of the knob is not parallel to the edge of the cover, the knob is withdrawn further against the action of the spring 36, the.sleeve 22 being held by the pin 23 engaging the end of the slot 24 so that the clutch is disengaged, and the knob is turned to the required position. When applied to a post binder, Fig. 7, the operating mechanism is housed in the binder bar 43. As shown the screw 49 has a reduced neck 50 which engages an upturned flange 51 of the locking slide 45, and is movable axially through a fixed nut 48. Holes 42 in the bar 43 and slide 45 receive the binding posts, and rotation of the screw 49 moves the slide 45 to clamp the posts in the holes 42. The bar 43 is shortened to accommodate the knob 53 within the boundaries of the binder and may be provided with recesses engaged by projections 54 on the knob in such position or the knob may be reduced at its inner end to fit into the open end of the bar as at 55. In other respects the operating mechanism is the same as before. In another form the screw 49 is held against axial movement and the nut which is movable is attached to the locking slide. In another form the screw is non-rotatable but movable axially, and the nut, in the form of an elongated tube held against axial movement and attached to the locking slide, is rotated by the operating mechanism similar to that already described, the sleeve, corresponding to the sleeve 22, carrying a pin working in longitudinal slots in the elongated tube.

Title: Improvements in or relating to wide angle optical picture projection
IPC: G03B37/00
Filed: 1954-03-23
Abstract: 787,746. Panoramic picture projection. AMERICAN OPTICAL CO. March 23, 1954 [April 6, 1953], No. 8517/54. Drawings to Specification. Class 97(1) In projecting panoramic, especially kine matograph images there is used a combination of film and projector such that, if the images were received on a normal flat screen, would be laterally foreshortened to an extent increasing from the centre to side edges, the image being received on a concavely curved screen which counteracts the image distortion, at least in part. The necessary "barrel" distortion of the projector/film combination may be provided by the projection lens or preferably may be incorporated in the film pictures during photographing or may be provided partly in each of these ways. It is explained that if a picture is taken with a camera with a wide angle lens without distortion and projected with a similar lens on to a cylindrically curved screen the pictures will be seen substantially undistorted only if the projector and observer are located near the screen centre. The provision of the distortion in projector or film permits projection from greater distances from the screen and provides a larger audience area within which the pictures are seen substantially undistorted The screen curvature is not necessarily circular in plan. The Specification explains how the curvature may be chosen to suit a particular shape of audience area. The screen may also have some curvature in vertical section. Details are given of a wide angle objective for providing the necessary image distortion when photographing.
