Title: Improvements in or relating to apparatus for tipping railway wagons
IPC: B65G67/00
Filed: 1922-06-07
Abstract: 202,766. General Electric Co., Ltd., and Marshall, C. H. June 7, 1922. Tipping - apparatus. -In side-tipping apparatus, the wagon is held and tipped by hauling on a pair of ropes 23 each connected through an equalizing bar to a pair of ropes 22<a>, 22<b> which are secured to a clamping- bar 25 and pass round coaxial guide - pulleys 20b so as to form a loop around the wagon, the rope 22a passing over a guide-pulley 20. The wagon is supported during tipping by a bolster 14 pivoted at 16 on arms 11 pivoted at 12 on fixed standards 13. The cradle 18, which carries the rail beams 19 and the guide-pulleys 20, 20<b>, is pivoted on the arms 11 at 17. The ends of the rail beams 19 normally rest on the ground so that the tipping-apparatus is relieved of the weight of moving traffic. On hauling the ropes 23, the clamping-bars 25 are brought down on to the wagon and the cradle 18 then turns about the pivot 17 until the wagon engages the bolster 14. The cradle then turns about the pivot 12, emptying the wagon and raising a counterweight 32. On releasing the ropes 23, the apparatus is righted by the weight 32, a small weight 28 serving to release the clamping-bars. When the bolster 14 is arranged above the pivot 12 as shown, the weight of the parts 11, 18, 19 helps to balance the weight of the loaded wagon during tipping. In a modification, Fig. 7, the arms 11 are pivoted at 12 on brackets in a rotary frame 34 mounted on rollers 35. The wagon is tipped about the centre of the frame 34. The movement is limited by a stop 36, and a counterweight 38 is connected to each frame 34.

Abstract: 642,531. Grinding cams &c. NORTON CO. May 29, 1946, No. 16309. Convention date, July 16, 1945. [Class 60] A machine for grinding oval automatic cams, ovalshaped pistons or other articles comprises a rotatable grinding wheel, a pivotally mounted rock bar, a rotatable work support on said bar to support a cam being ground, a rotatable master cam on said rock bar in axial alignment with the cam to be ground, a follower roller arranged to engage the master cam, a pivotally mounted frame to support said roller, means to maintain said master cam in engagement with said roller, and a link the ends of which are respectively pivotally connected to said rock bar and said frame, the link being adjustable relatively to said rock bar and said frame to compensate for reduction in diameter of the grinding wheel or for determining the length of the minor axis in the finished article. The grinding wheel 20 is mounted on a slide 21 movable transversely on the machine base 10 by a screw 32 operated, through gearing, by a handwheel 29 having micrometer feed adjusting mechanism 30 as described in Specification 6784/01, [Class 60]; the grinding wheel is belt driven from an electric motor 24 carried by the slide 21. The work 42 is carried at one end in a work-holder 41 on a headstock spindle 40 carried by a rock bar 35; the other end of the work is supported by a centre 43 in a footstock 44 adjustably carried by the rock bar 35. The rock bar 35 rocks upon trunnion studs 36, 37 journalled in brackets 38, 39 carried by a work table 11 which is movable longitudinally on the machine base 10 by power or manually, as e.g. by rack 19 and pinion actuated by handwheel 15. The headstock spindle 40 is driven through a telescopic shaft 54 and universal joints 53, 55 from a shaft 51 mounted on the work table 11 and belt driven by an electric motor 46 mounted on the work table 11. A master cam 58 is supported on the headstock spindle 40 and cooperates with a roller 60 carried by a frame 62 pivoted at 63 to a bracket 64 mounted in a housing 45 secured to the work table 11. A tension spring 80 is connected at one end to a stud 81 adjustable in the housing 45 and at the other end to an arm 84 secured to the rock bar 35 so as to maintain the master cam and roller in contact. A link 70 is: connected between a pivot stud 71 on the frame 62 and a pivot stud 72 on the rock bar 35; the studs 71, 72 are adjustable relatively to the frame 62 and rock bar 35 respectively by screws 73, 74. It is stated that,. with a given grinding wheel and given master cam, such adjustment of stud 71 and/or stud 72 increases or decreases the length of the minor axis produced on the work, the major axis remaining unchanged. To maintain a desired shape of work despite reduction in size of the grinding wheel due to wear and/or trueing, compensation on the minor axis is effected as just described and compensation on the major axis is effected by feeding the grinding wheel closer to the work.

Title: Improvements in devices for sharpening the rotary circular knives of slicing and other machines
IPC: B24B3/46
Filed: 1924-07-09
Abstract: 229,926. Berkel, C. F. M. van. July 9, 1924. Machine cutters, grinding in situ.-The rotary knife 41 of a slicing-machine &c. is sharpened by a grinding-wheel 14 and a burr-removing wheel 20 moved into and out of operative position by mechanism so arranged that the burrremoving wheel is moved away from the knife. after the grinding-wheel has been moved away. The device comprises a casing 7 carried by a pin 8 which rests on the machine bed 1, and is rotatable and slidable in a sleeve 3 having a flange 4 bevelled at 35. Within the casing is a shaft 10 rotatable, in one direction only, by a handle 11, and on the shaft are mounted a disc 25 with a slot 24 therein, and a spiral gear 26 driving a shaft 28 carrying two cams 29, 30. The grinding-wheel 14 is mounted on a shaft carried by a sleeve 14a, which is pressed by a spring towards the knife 41 and is slidable in an angularly-adjustable sleeve 15, and on the sleeve 14<a> is an arm 16 which co-operates with the cam 29. The burr-removing wheel 20 is mounted similarly and is moved bv the cam 30. On a shaft 32 is a finger 31 adapted to engage the slot 24, and on the shaft also is mounted a hook 33 having a recess 34 adapted to engage the edge 35 of the flange 4; a spring 36 tends to disengage the finger 31 from the slot 24. In the flange 4 are two holes 37, 38 adapted to be engaged by a pin 39 on the casing 7. In operation, the handle 11 is turned by 90‹ steps, being retained in these positions by a spring-pressed bail 13. Movement of the handle to a horizontal position removes the cam 29 from arm 16, allowing the grinding-wheel to move into operative position. The next movement of the handle allows, by movement of the cam 30, the burr-removing wheel to move into operative position. The next movement of the handle removes the grinding- wheel, and the last movement of the handle moves the burr-removing wheel from the knife. When the sharpener is out of use, the casing 7 may be raised, provided the handle is in correct position, to bring the slot 24 opposite the finger 31, and rotated so that the pin 39 may, on lowering the casing, drop into the hole 38 with the sharpening-wheels away from the knife.
