Title: Improvements in or relating to carriages for lathes
IPC: B23Q5/34
Filed: 1943-02-15
Abstract: 561,727. Cam mechanism. TAREX, S. A. Feb. 15, 1943, No. 2479. Convention date, March 14, 1942. [Class 80 (iii)] [Also in Group XXII] An automatic lathe having a lower crossslide 6 and an upper longitudinal slide 11 actuated by cams 5, 8 respectively has means for adjusting the effective length of the cam 8 so that different longitudinal traverses may be effected without changing cams. The cam 5 which is mounted on a shaft 4 acts through a toothed sector engaging a rack 26 on the slide 6. The cam shaft 4 is connected by bevel gearing 10 to the shaft 9 of the cam 8 which acts through a slotted bell-crank lever 22 carrying a screw-adjusted pin 20 engaging a slot 19 in a head 18 secured to a sliding rod 14 which through an adjustable abutment screw 17 engaging a rib 17b imparts positive movement to the slide 11, return being effected by a spring 12. The return is limited by an abutment screw 25 so that by adjustment of this screw, which alters the starting position of slide 11, the effective length of cam 8 is altered and different longitudinal traverses may be effected by the same cam. The screw 17' provides a second adjustment for the feed of the slide 11 since for any set position of the screw 25 the length of rod 14 may be increased or decreased to deterinine the extent of the feed movement to the right. The cam 5 consists of two parts 5a, 5b having inter-engaging serations so that the parts may be adjusted on each other to vary the length of the peripheral arcuate surface 33b, Fig. 4, the cam as a whole being adjusted on the shaft by a serrated ring 43 coacting with serrations on a fixed ring 41. The pin 20 is adjusted along its slot to vary the speed of the feed movement in accordance with the material being macliined. The length of the circular part of the cam 5 is adjusted to vary the time of the dwell of the cross-slide in its forward position and this is set in accordance with the time required for the effective part of cam 8 to impart the longitudinal feed. The cam 8 may also be adjustable on its shaft. By the above-described adjustments the machining operations are effected during the maximum fraction of the revolution of cam-shafts 4 and 9 and both cam-shafts may be speeded up during the non-operative part of their rotation thus minimising production time. In a modification, in order to avoid variations in the speed of feed rod 14 due to the angularity of lever arm 22 to the cam 8, Fig. 7, acts through a sector 50 on a slide 53 carrying a head. 56 provided with a slot 57 engaging a pin on the rod 14 so that by angular adjustment of the head the speed of the rod 14 may be varied. In this case the abutment 17 is arranged to effect the working feed of the slide 11 to the left, Fig. 7.

Abstract: 1,219,882. Selective printing, ADDRESSOGRAPH MULTIGRAPH CORP. 17 Jan,. 1969 [18 Jan., 1968], No. 2975/69. Heading B6F. A credit card data-printing machine comprises a base (12), Fig. 1 (not shown), including a printing bed (16) and having a printing head (14) including a roller platen carriage (15) pivotally mounted thereon by a shaft 13, Fig. 3, the printing head (14) being movable from an open position away from the bed (16) to a closed position against the bed (16), locking means being provided whereby the printing head cannot be moved to the closed position for a printing operation until at least one of a plurality of print wheels such as P3 has been reset. Index-setting arrangements.-Each print wheel is formed with an integral pinion 44 which is engaged by a gear-wheel 42, the gear-wheel 42 having an integral extension gear 41 engaged by an idler gear 36 which is driven by a pinion 32 integral with an index wheel such as W3 formed with a knurled flange 35 and a hub 30 bearing characters corresponding to those on the print wheel P3. The gear-wheels 42 and respective integral extension gears 41 are rotatably mounted on a fixed shaft 48, the shaft 48 including detents each comprising pointed caps 64 urged apart by a spring 65 into recesses 68 in the inner surface of a bore in the respective gear-wheel. The extension gears 41 permit the index wheels to be spaced further apart than the print wheels. Interlocking devices.-Moving the printing head to the closed position for a printing operation causes, through gear segments 92, 88, a cam 86, a projection 84 and a spring 75, pivotal movement of a shuttle 76 about an axis 78. Such movement brings pawl teeth 72 into engagement with the print wheels for alignment and locking action, causes an adjustable stop 126 to engage a cradle 100 to pivot the cradle about a pin 82 and bring a roller 103 into engagement with pairs of teeth on the gear-wheels 42, the cradle being held in this position by an over-centre spring 112, and acts through a projection 142 to urge a lever 130 having an ear 138 projecting above the bed (16) so that the ear 138 is aligned with a notch (17, Fig. 1) in a wall of the printing head (14). After printing, the printing head is swung back and the shuttle 76 returns to release the print wheels, and return the lever 130 under spring bias to a position wherein the ear 138 is not aligned with the notch (17). The cradle 100 is held in place by the spring 112. The printing head cannot then be returned to the closed position owing to a blocking lever 120 pivoted at 82 and engaging a pin 80, thus preventing pivotal motion of the shuttle 76 and consequent movement of the lever 130, so that the ear 138 is engaged by the side wall of the printing head. Resetting of at least one print wheel is necessary, this acting to return the cradle 100 over-centre of the spring 112, bringing the lever 120 out of a position engaging the pin 80 and thus permitting pivotal movement of the shuttle 76.
