Title: Folding machine for folding letters, printed matter or the like
IPC: B65H45/14
Filed: 1930-05-26
Abstract: 353,156. Paper-folding machines. WEIDNER, E., 26, Alexandrinenstrasse, Berlin. May 26, 1930, No. 16113. [Classes 100 (i) and 100 (ii).] In a buckling folder for folding printed matter, letters, &c., the pair of guide rollers 5, 6 are so arranged relatively to the feed-table 2 and the stop-plate 17 as to bend the sheet in the direction of and cause it to enter the plate 17 without liability to crumpling by impact with the plate. For this purpose, the axis of the lower roller 5 is not vertically below the axes of the upper roller 6, but is situated nearer to the plate 17. Further, the roller 10 co-operating with the roller 5 to complete the fold has its axis above the horizontal plane containing the axis of the roller 5, so that the once-folded sheet is fed up the stop 26 of a second stop-plate 24 without impacting with the plate 24. The rollers are all made of non-metallic substances which are non-conductors of electricity, such as rubber, synthetic resins, linoleum, ebonite, artificial stone, or ceramic materials, to minimize the likelihood of sheets adhering to one another due to becoming charged with electricity. The central roller 5 preferably has a relatively soft coating of rubber. Delivery apparatus.-A roller 13 co-operates with the roller 5 to deliver the folded sheet over a guide 35 to a receiver situated beneath the table and comprising two side members 27. 31, the former of which has a bottom member 29 mounted thereon which is lowered by hand by means of a set-screw 30 as the pile of sheets increases.

Abstract: 1,093,543. Sawing. ETABLISSEMENTS GUILLIET. April 14, 1966, No. 16352/66. Heading B5L. A band saw comprises a workpiece carriage supported by rollers on oblique axles upon a roller track, and transverse guide members which in a feeding movement of the carriage prevent lateral movement of the carriage, but in a return movement permit a transverse movement to the carriage to disengage the workpiece from the band-saw blade. The carriage consists of a pair of longitudinal beams 6a, 6b interconnected by cross-beams 7a, 7b, and a pair of obliquely-disposed axles 3a, 3b having rollers 4a, 4b engaging tracks 5a, 5b along which the carriage is movable to convey a workpiece towards and from the bandsaw blade 33. The cross-beams 7a, 7b carry the transverse guide members comprising rollers 8a, 8b which are mounted on fixed axes for engaging the outer surface of track 5b, and rollers 9a, 9b which engage the inner surface of the track and are mounted on levers 11a, 11b rockable about pivots 12a, 12b between stops 13a, 13b, 14a, 14b to position the rollers 9a, 9b relative to the rollers 8a. 8b a distance equal to or greater than the width of the track 5b. The levers, at one end, have extensions 17a, 17b which frictionally engage the track 5b, and at the other end have extensions 15a, 15b interconnected by a rod 16 connected by a clamp 19 to a cable 18 for moving the carriage towards and away from the saw-blade 33. During the forward movement of the carriage in the direction F, the action of the rod 16 and the friction on the extensions 17a, 17b swings the levers 11a. 11b against stops 13a, 13b so that the rollers 8a, 8b, 9a, 9b simultaneously engage the track to prevent lateral movement of the carriage. On the return movement, the levers rock about pivots 12a, 12b into engagement with the stops 14a, 14b so that the distance between the rollers 9a, 9b and rollers 8a, 8b is greater than the width of the track 5b and the obliquely disposed rollers causes the carriage to move laterally at the commencement of the return movement to disengage the workpiece laterally from the blade 33. In another embodiment, the movement of the levers is effected by manual operation of a rod connected by an intermediate lever to the lever 11b. A locking-pin 27 is provided to retain the rollers in the position shown in Fig. 1 if desired during the return movement.

Abstract: 1,220,194. Applying power to vehicle wheels. COMMISSARIAT A L'ENERGIE ATOMIQUE. 1 April, 1969 [9 April, 1968], No. 17063/69. Addition to 1,217,285. Heading B7H. An arrangement for controlling the speed of rotation of the wheels 4 of a vehicle, the pivoted axes 3 of the wheels being disposed at the vertices of a polygon which is located in a base plane and which can be inscribed within a base circle, and each wheel having individual driving means 5, is characterized in that any two adjacent wheels are driven with a speed ratio which is in the same ratio as the lengths of straight line segments DF and FE which are cut on a chord DE of a reference circle 14 (which passes through pinions 7 and is transformed from the base circle by the diameter of pinion 9) which joins the pivotal axes of the two wheels, by a line bisecting the angle DCE defined by two lines in the reference plane which connect a vertical projection of the centre of rotation to the two pivotal axes. A vehicle 1 has wheels 4 with pivotal shafts 3 which can be connected to a pinion 6 or 7 by a dog clutch 8. The pinions 7 have guides 11 which engage a pin 12 which is movable in a slot 13. Dependent on the coupling of the shafts 3 to one or other of the pinions 6 or 7, then such an arrangement allows the centre of rotation of the vehicle to vary within the base plane and to correspond to a transformed point thereof when the centre is within the base circle or a conjugate of the point within the reference circle when the centre is outside the base circle. In Fig. 2, C denotes the axis of pin 12 and 14 is the reference circle through pinions 7. Bisecting of angle DCE is achieved by a fork 15 being connected to forks 11 by link-rods 16 and 17. The fork slides along DE and a movable contact 18 of a linear potentiometer contacts a resistor 19. The voltages thus collected are transmitted by electrical connections 20 to the motors 5. The speed of the motors is dependent on the reference voltage between the ends of the resistors 19 which is variable to vary the vehicle speed.
