摘要： 311,328. Cincinnati Grinders, Inc., (Assignees of Booth, C.). May 9, 1028, [Convention date]. Centreless grinding; guides and rests. - A centreless grinder for tapered rollers consists of a bed 15 having adjustably mounted thereon a grinding-wheel 18, which is reciprocated axially during grinding, and a regulating-wheel 19. Supported on the bed below the wheels is a cam plate 27, reciprocated parallel to the wheel axes by a lever 29 oscillated by a cam groove 34 in a drum 35 on the shaft of the regulating-wheel. The cam plate has thereon three cams 37, 38, 39, the cams 37, 38 serving, through contact with rollers carried by vertical rods 47, 48, to raise and lower a work rest 50, which in its lowest position carries the work-pieces 69 into the grinding-throat, and in its highest position carries the work-pieces up to a discharging and feeding mechanism. This mechanism consists of a hopper 53 having passages 54, 55, 56 therein along which the work-pieces are fed to starwheels 58 carried by a shaft 57 rotated intermittently by ratchet-gearing 60, 61 actuated, through a member 63, by the cam 39. The arms 59 of the star-wheels discharge the workpieces from the recesses 68 in the work-rest into a shoot 65, and feed new, unground, pieces into the recesses ready for grinding when the rest is lowered; adjustable positioning screws 71 are provided in the rest to engage the ends of the work-pieces. The regulating-wheel is formed with tapered flanges 74, 75, 76, one to engage each work-piece, and the grinding-wheel is cylindrical.

摘要： 299,799. Cincinnati Grinders, Inc., (Assignees of Einstein, S.). Nov. 1, 1927, [Convention date]. Centreless grinding :round holes, enlarging and trucing;trucing rotating tools; guides and rests. A centreless grinding machine for grinding simultaneously the exterior and interior surfaces of tubular articles, consists of a grinding-wheel C rotatably mounted on a bed A, a regulating-wheel 22 movable with a slide 16 towards and from the wheel C, an internal grinding-wheel 46, and a work-rest 18 carried by the slide 16. The slide 16 is moved up to the wheel C, to reduce the work to size externally, by a cam 34 driven by a motor 28 and adapted to oscillate a lever 35 engaging a screw 40 adjustable by hand to position the regulating-wheel to suit the diameter of the work and to compensate for wear of the wheel C, and on completion of grinding the slide 16 is retracted to allow of ejection of the work by an ejector 24 actuated by a ratchet wheel 84, which is rotated, through rack and pinion and ratchet and pawl gearing 89, 90 by the reciprocation of the slide 16. The internal grinding-wheel 46 is mounted on a cross slide 42 on a slide 41 movable on the slide 16 by a cam 55 and a lever 58 engaging a screw 62 adjustable by hand in the slide 41, the cam being rotated through bevel gearing and a telescopic shaft 51 from the motor 28; the wheel 46 is driven by a motor 47. The axis of the regulating-wheel 22 is inclined to the horizontal to hold the work, during grinding, against the ejector 24. The wheel 46 is reciprocated axially by means of a cam groove 73 in the boss of a pinion 66 secured to the spindle 45 of the grinder, a pin 72, engaging the groove, being carried by a pinion 67 driven through gears 68 from the pinion 66. The reciprocation may be started or stopped by movement of a lock-washer 70 by means of a handle 71, to prevent, or permit of axial movement of the pinion 67; a lock-nut 7G also may be used positively to prevent the reciprocation. The wheel 46 is trued by a trueiugdevice 77, Fig. 11, adjustable by a handle, the reciprocation of the wheel being stopped during trueing. In operation, the work is first reduced nearly to size externally by the action of the wheels C, 22, the internal grinding-wheel 46 being out of contact with the work. When the work is nearly to size externally the internal grinder is brought up to the interior surface by the cam gearing 55, the work when to size being ejected automatically by the ejector 24. In order to steady the work when first introduced a roller 90 is provided carried by a spring-pressed arm 91.

摘要： 300,061. Hughes, V. A. B., (Cincinnati Grinders, Inc.). Feb. 24, 1928. Centreless grinding; guides and rests. - A centreless grinding machine is adapted for producing accurately concentric but differentlyshaped surfaces on work-pieces, such as the cylindrical body and tapered shank of a twist drill. The fluted body N, Fig. 3, of a twist drill is produced in a centreless grinding machine in the usual manner and is then gripped in a split collet 13 clamped by a hand-wheel 15 within a work-holder 10 having a cylindrical portion 11 concentric with the collet. The holder is rotatably mounted on the usual work-support M, Fig. 2, by means of a half-bearing 17 and a blade 18 having an upper inclined surface engaging the portion 11, a roller 22 being pivotally mounted on the support, and urged by a spring so as to force the portion 11 against the regulating wheel D. In operation, several work-holders are used in turn, and with a work-piece mounted therein being placed on the support M while the latter is raised by means of a hand operated pinion I engaging a rack on a controlling plunger G to which the support is secured, the roller 22 being moved to one side by a hand lever 28 to allow admission of the holder. On lowering the support the holder is rotated by contact with the regulating wheel D and a grinding wheel E, Fig. 3, which is staggered with regard to the wheel D, is fed in by its slide to cut the correct taper. The wheel E may be dressed to the required taper or alternatively its slide may be inclined. When a work-piece has been completed the holder is removed from the machine and replaced by another holder with a work-piece to be operated upon whilst the previous holder is having its work-piece renewed.

摘要： 531,735. Grinding cambered rollers &c. CINCINNATI GRINDERS Inc. July 31, 1939, No. 22200. Convention date, Nov. 7, 1938. [Class 60] A machine for grinding a camber on a roller or other work piece 14 comprises a driven grinding wheel 15 on a slide 47 adjustable on a support 49 which is pivoted at 50 and supported, through a lever 53, Fig. 2 by a cam 44 the eccentricity of which can be adjusted by means of an eccentric driven sleeve 43, Fig. 3, between the cam 44 and a fixed bearing 42, a pin 70 being provided to connect the cam to the sleeve. The cam 44 has a cylindrical face 45 to engage the follower 55, Fig. 2, of the lever 53, this being lifted out of contact by a bolt 73 before adjusting the throw of the cam. The pin 70 is then withdrawn and the cam 44 pulled, with the loosely connected gear 38, to withdraw fine teeth 40 thereon from corresponding teeth 41 on the sleeve 43. The bore of the cam 44 engaged by the sleeve is eccentric to the same degree as the outer face of said sleeve and when these parts are adjusted to oppose these eccentricities, as shown in Fig. 9, the face 45 is concentric with the bearing and a mark 63, Fig. 5, thereon is in line with zero marks of scales on flanges of the sleeve 43 and cam 44. If these parts are adjusted in opposite directions to bring the identical scale readings in line with the mark 63 the centre of the cam face will be moved directly towards the follower 55, for producing a concave camber, or away for a convex camber. The sleeve 43 is then pushed in to re-engage the teeth 40, 41 the pin 70 inserted in one of the holes 69 found to be in line with one of the holes 68 and the lever 53 is released. The grinding wheel is now at the crest of the camber to be formed and the work slide 13, Fig. 1, and cam 44, Fig. 3, which are interconnected by gearing 23, 25, 26, 31, 32, 37, 38 are reciprocated and rotated, respectively by a motor 79 in one direction and, to avoid back lash, by a motor acting on the slide 13, in the other direction.The crest of the camber is usually required at the longitudinal centre of the work 14 which is mounted on head and tail stocks and rotated by means not shown but the slide 13 may be adjusted to bring any part of the work opposite the grinding wheel when setting the cam.
