Class 100(1) Apparatus for delivering sheets to a belt in overlapping relation, or to a pile, comprises means such as rotating rollers or travelling driven means which corrugate the sheets longitudinally to stiffen them, in combination with a stationary surface which receives the sheets from the rollers &c. and shaped to preserve the corrugations and so facilitate the overlapping or stacking operations. As shown in Fig. 1, sheets cut from a web are delivered by fast moving belts 1, 3 between a pair of corrugated rollers 5, 6, and the corrugated sheets then pass over a stationary table 23 having an upper surface of wave-like form to suit the corrugations in the sheets. The sheets on leaving the table 23, are delivered on to a slower moving conveyer 21 and beneath a driven roll 28 which reduces the speed of the sheets and controls the overlapping thereof. The roller 6 carries the tapes of the conveyer 1. Conveyer tapes 19 co-operate with the conveyer 21, and these pass between the rollers 5, 6 to a roll 20. The roller 5 has its end bearings carried in arms 8 pivoted at 9, and these can be adjusted by screw means 11, 13 relatively to the roller 6. In the form shown in Fig. 5, sheets cut from a web by a rotary cutter 29 are delivered by fast moving tapes 31 on to slower moving tapes 32 in overlapping formation, means being provided, as described above, for corrugating the sheets during the overlapping operation. The conveyer tapes 32 deliver the sheets over a stationary corrugated plate 43 (not shown), between corrugated rollers 46, 47, over a corrugated stationary plate, and then between a pair of rollers 63, 64 which are corrugated but have their protruberances oppositely disposed. The sheets are delivered against a stop 34 and on to a pile 33. The conveyer tapes 32 are carried on a frame 35 pivoted at 36 at one end, and suspended at the other end from a vertically movable carriage 38 by a link 37. The carriage 38 is moved along guides in a frame 39 in known manner so that sheets are delivered over the top of of the pile as the pile grows. The pairs of rollers 46, 47 and 63, 64 are geared together and driven. The lower rollers 47, 64 are vertically adjustable, and the upper rollers 46, 63 have their bearings carried by pivoted arms which can also be adjusted. The stationary corrugated table or plate can be replaced by a pair of relatively slidable plates to provide a support adjustable in length.

Title: New and improved handle and latch mechanism
IPC: E05B65/20
Filed: 1936-12-10
Abstract: 471,141. Door-latches. OTTINGER, L. Dec. 10, 1936, No. 33940. Convention date, Dec. 19, 1935. [Class 44] A door latch, particularly for motor cars, has a rotary actuating shaft 10 with an operating handle 8 normally lying close to and substantally parallel with the face of the door, and the shaft is disposed obliquely to the door so that the handle moves away from the door face as it is turned to retract the latch bolt 5. The door surface may be recessed as shown in Fig. 2, to permit an easy grip of the handle to be obtained ; the escutcheon plate 14 is flared under the door surface and is packed up with resilient material. The movement of the bolt 5 is limited by a flexed post 16 engaging the ends of the slot 17. The roll-back of the latch is supported in journals in bearing plates 18, 19, the latter 19 being mounted on the face plate 3 and a foot member 20, while the former 18 is supported by the plate 19. The end of the handle shaft 10 is flattened and fits in a slot in the roll-back ; the nose 24 of the roll-back engages a lug 25 near the lower end of a pivoted lever 26 to which is pivoted the dog 29 for operating the bolt 6. When the handle is turned clockwise the nose 24 of the roll-back forces the dog 29 to engage the shoulder 30, after the lost motion between the dog and shoulder has been taken up, and so retracts the bolt. The outer end of the handle shank 11 is provided with a cylinder look operated by a key. A pair of balls 35, 36 positioned within the handle shaft 10, coact with the forked end of the lever 31, and when the key is rotated in one direction the lever is operated by the ball 35 to move the dog 29 to the position shown in Fig. 4, where it can retract the bolt. When the key is rotated in the other direction the ball 36 operates the lever to withdraw the dog 29, so that the handle can be moved without retracting the bolt. In a modification the base plate is formed to provide a portion 40, Fig. 6, at right-angles to the axis of the handle shaft, and the roll back 47 has an actuating nose 48 displaced angularly from the body of the roll-back as shown in Fig. 11. In 'a further modification the latch mechanism is mounted in the usual way, and its rotary member is connected to the handle shaft by a universal joint 52, Fig. 13. In another modification the upper part of the door is thinner than the lower part and the external handle 60 is mounted on the sloping portion 9c, Fig. 20. An inside handle 63 is mounted on an extension 64 of the handle shaft, and is held yieldingly in an upright position by a spring-pressed plunger 68. As the handle is turned its end moves over a wearing plate 70 mounted to protect the upholstery.
