Abstract: 485,364. Railway vehicle bogies. SCHWEIZERISCHE LOKOMOTIVUND MASCHINENFABRIK. Nov. 8, 1937, No. 30567. Convention date, Nov. 9, 1936. [Class 103 (vi)] In a single or multi-axle radial bogie for railway vehicles having spring-controlled contralizing means, the latter are disposed substantially directly above the axle, while the effort of the springs is adapted to become operative on a very slight deviation of the bogie from the normal position and to remain substantially constant up to the maximum deviation. In the arrangement shown in Fig. 1, the frame c of a Bissel bogie carrying a single axle a is pivoted at d to the vehicle underframe and is provided with a pair of spring-controlled arms h, which are pivoted at h<1> to a transverse beam g and fitted at their ends with rollers i bearing against inclined surfaces k on a wedge member k<1> secured to the underframe. The controlling springs m are inserted in a state of initial compression and thus become immediately operative on a small deviation, while owing to the movement of the rollers i on the surfaces k the effective leverage of the springs remains practically constant on further deviation. In a modification, Fig. 2, the wedge member k<1>, instead of being secured to the underframe, is mounted upon but slidable laterally relatively to the axle casing g<3>, being held in the central line of the vehicle by a vertical pin o on the underframe entering a corresponding recess in a block p on the wedge member.

Abstract: 875,503. Winding and reeling. UNITED ENGINEERING & FOUNDRY CO. Oct. 1, 1957 [Oct. 1, 1956], No. 30651/57. Class 83 (4). A belt wrapper for use in conjunction with a reel for coiling strip thereon comprises a main frame and an end frame between which is mounted a plurality of rollers for supporting an endless belt, the end frame being rigidly supported from the main frame to form a cantilever structure such that clearance is provided around the entire periphery of the end frame whereby when tension is removed from the belt it may readily be removed and replaced by passing it over the said end frame. A belt wrapper 11, movable on wheels 15 along a track 16 to and from a reel 12 by piston and cylinder means 18, includes a vertical central main frame 13 secured on a platform 14 and two end frames 25 parallel to and spaced from the frame 13 and connected thereto by tubes 26, separator plates 27 and crescent-shaped plates 28. A rear upright plate 23 perpendicular to the plate 13 is secured thereto and to the platform 14 and a reinforcing T-shaped plate 22 is secured to the tops of the plates 13 and 23. The frames 13 and 25 support rollers 32, 33, 34, 35, which taper towards their ends, over which run belts 39. Rollers 36 on arms 40 pivoted at 41 to the frames 13, 25 also guide the belts 39 and rollers 37, on yokes 43 guided by rods 46 slidable in blocks 47, are normally held by piston and cylinder means 44 in engagement with the outside of the belts 39 to tension them. As the wrapper 11 is moved along the track 16 to the reel 12 a roller 56 on a lever 55 pivoted to the frames 13, 25 runs along a cam track 57. The lever 55 is linked by means 53, 52, 48 to the arms 40 and, just prior to the engagement of the belts with the reel 12, the roller 56 drops off the track 57 in front of a stop 59 engagement therewith causing the arms 40 to pivot down to bring the belt into reel-engaging position. As the strip builds up on the reel 12 the arms 40 are forced outwardly causing the stop 59 to yield against a spring 62. After several turns are wound the wrapper 11 is withdrawn. When the belts 39 are to be removed the means 44 retract the rollers 37 and the belts are slipped off over the end frames 25. U.S.A. Specification 2,309,781 is referred to.

Filed: 1958-09-25
Abstract: 897,058. Sewing machines. SINGER MANUFACTURING CO. Sept. 25, 1958 [Oct. 2, 1957], No. 30656/58. Class 112 [Also in Group XXIV] In a cyclically operated sewing machine wherein a lever 28, controlling the driving clutch 21, 23 and a positive stop 33, is actuated by the machine treadle through a lever 48, link 45, latch lever 43 and adjustable link 40, the arrangement is such that as the lever 28 is turned anti-clockwise about its fixed pivot 29 in moving from a stop position, shown, through an intermediate free position to a clutch-engaged position, the line of action of the link 40 approaches and finally substantially lies on the fixed pivotal axis 44 of the latch lever 43, whilst that of the link 45 becomes perpendicular to its effective latch lever radius 44, 46. Increased mechanical advantage for the final clutch engaging operation thereby obtained reduces the operator's treadle effort. A spring- loaded pawl 55 retains the latch lever 43 in the intermediate free, or final clutch-engaged position and is released through a handle 60 or automatically through a link 61 by a pattern cam. The latch lever 43 is interlocked by projections 70 with a work-clamp opening shaft 66 which is actuated through a lever 69 and a link 68. The clutch is of the kind in which a drive-belt is gripped by its driven pulley which latter comprises a flange 21 fast cn the machine shaft 12 and a freely mounted flange 23 moved axially leftwards, to grip the belt, through a thrust bearing 25 contacted by an arm 27 fast to the lever 28. The lever 28 pivotally carries a stop arm 33 which engages a stop notch 34 in the fast flange 21 to stop the shaft 12 in a predetermined position and is pivoted at its extremity to a plunger 35 resiliently centred by springs 37 to absorb shock. The lever 28 is biased into its stop position by a spring 38.

Title: Improvements relating to machines for dividing a sheet into discrete units
Inventor: GRUVER JOHN H
IPC: B65C1/02
Filed: 1969-06-17
Abstract: 1,216,808. Perforating and tearing. ADDRESSOGRAPH MULTIGRAPH CORP. 17 June, 1969 [18 June, 1968], No. 30690/69. Heading B4B. [Also in Division B8] A machine for dividing a sheet 12 into a number of unit portions, e.g. printed address labels 15, comprises means 17 for feeding the sheet past perforating wheels thereby forming rows of perforations, a blade 20 for severing the sheet into strips and means 55, 56, 66, 68 for applying a tension to-the strip so as to sever the strip at a line of weakness thereby separating a label therefrom. The sheet is fed through the machine by means of pin-wheels 17 mounted on a rotary shaft 18 and engaging with holes 16 in the edges of the sheet. After the sheet is guided the perforated edges are removed by disc cutters 19. The disc cutters and perforating wheels for forming lines of weakness in the sheet are mounted on a shaft supported by arms 37 pivoted on a shaft 38, the arms being urged downwardly by means of springs 41 so as to cause the perforator wheels and cutters to engage with an anvil on the shaft 18; the wheels and cutters are maintained in this position against the action of the springs 41 by means of a latch (43, Fig. 4). The blade 20 is mounted on levers 21, Fig. 3, secured to a pivotable shaft 22, the levers being moved downwardly so that the blade effects a cutting stroke by means of cams 26 engaging with followers 27 on the levers. The blade is returned by means of cams 25 cooperating with followers on levers 23. The severed strip is fed by means of co-operating rollers 52, 54, Fig. 5, into the nip of rollers 55, 56, the roller 55 having a pad surface (59, 60, Fig. 8) which is adjustable to suit labels of different lengths. The end of the strip is fed by the latter rollers into the nip of a second pair of rollers 65, 68 which rotate at a faster speed than the first pair. The roller 65 has a pad surface 66 provided with suction holes so that after a label has been severed from the strip at a line of weakness it is carried by the pad and transferred therefrom to a suction pad 72 on a roller 71. The pad 72 carries the label past a glue applicator wheel 75 and is then pressed by the pad 72 on to an article, e.g. a magazine, as the latter passes along a table under the wheel. In a modification, the pad 72 may be provided with heating devices which will enable the pad to heat and soften reverse printing on the back of the label or unit portion and cause the units to act as printing masters instead of applied labels.
