Title: Improvements in or relating to paper folding machines
IPC: B65H45/14
Filed: 1932-02-29
Abstract: 394,436. Paper-folding machines. BECK, A. E., (Representative of Beck, A. E.), 45, Tressillian Road, Brockley, London.-(Brehmer Geb. ; Plagwitz, Leipsic, Germany.) Feb. 29, 1932, No. 6054. [Class 100 (i).] Delivery apparatus.-In a machine for imparting parallel and perpendicular folds to paper sheets, a detachable conveyer-band 29 is provided. which can be placed over rollers 6, 17 between two sets of folders so as to deliver sheets directly from the first set of folders. As shown, the invention is applied to a buckling- folder machine in which the rollers 2, 3 form part of the parallel folders. The roller 6 which is carried by a lever 40 and normally delivers the sheets to a roller table 8 conveying the sheets transversely to the cross folders, is situated above the level of the table 8 so that successive sheets shall not foul each other. If further folding is not desired, the roller 6 is lowered and the conveyer-band 29, the ends of which can be connected by a " zip " or sliding- clasp fastener, is passed around the roller 6 and a roller 17 carried on a spring-pressed arm 35. A connecting-rod 18 pivoted to a crank on a gear 19 on the lever 40 is connected to a ratchet-arm 20 normally hanging loosely from the spindle 38 of the roller 6. When the roller 6 is lowered, the gear 19 meshes with a driving gear in the machine and thus, through the connecting rod 18, operates the ratchet arm 20 so that the band 29 is slowly and intermittently advanced. Similar alternative arrangements of conveying table or collecting band may be arranged between the cross-folders and a third set of folders. The tables may consist of inclined rollers, or in the case of the second table may consist of parallel rollers which forward the sheets to discs on inclined shafts to impart a transverse feed in a well-known manner. The discs may be moved apart to allow the sheet to continue in its original path and out of the machine.

Title: Improvements in and relating to the moulding of cells and cases from glass and the like
IPC: C03B11/00
Filed: 1925-03-13
Abstract: 230,846. Rosengarth, F. March 14, 1924, [Convention date]. Pressing.-A method of moulding cells or cases, such as accumulator cases, from glass or like plastic material consists in using a mould with a, fixed bottom and having sides that can be moved inwards towards a core, the glass being pressed by the inward movement of the sides. The machine comprises a bedplate 29, a mould table 3, and four uprights 31 on which a spider frame 37 slides. The mould consists of a bottom 1 mounted on a base plate 2, side plates 4 which are pivoted to the base, and vertical corner pieces, also pivoted to the base, which fill in the spaces between the side members. The bottom 1 has upturned edges, and the meeting-faces 33 between the bottom and sides are curved in order to maintain a close joint. The sides 4 are connected bv links 24 with nuts 20 on screwed spindles 21, and the spindles are carried by a frame which is movable vertically by means of a screw 18 controlled by a handwheel 12. Thus by turning the wheel 12, the frame can be moved to open or close the mould, the spindles 21 enabling the side plates 4 to be adjusted individually. The core consists of two parts 6, relatively movable to one another, one of the parts being formed with a hollow stem 36. The two parts are keyed together on their meeting faces and are connected with one another by a draw-rod 27 housed within the stem 36. The parts are locked together in the position shown in Fig. 1, but by turning the rod 27 so that its foot lies within a recess 43 between the faces, the left hand half can be raised first, as shown in Fig. 5. The crosssection of the core can thus be reduced to enable it to be withdrawn from the finished article. The stem 36 is secured to the spider 37 and is raised and lowered by a hand wheel. In use, the core is lowered into the mould until it is a correct distance above the bottom. The mould, which has been heated, has its sides opened to a sufficient distance and a charge of metal is delivered between the sides and the core. The handwheel 12 is then turned to close the sides of the mould and to press the glass. Any excess metal that may be pressed out of the mould is cut off by means of a blade 25 which rotates about the stem 36 and moves close to the top of the mould. The Specification as open to inspection under Sect. 91 (3) (a) describes a construction in which the two parts of the core are separated by a wedge that is withdrawn partly when the core is to be contracted. This subject-matter does not appear in the Specification as accepted.
