Abstract: 361,969. Cutting- confectionery &c. ROSE, A. G. and ROSE BROS. (GAINSBOROUGH), Ltd., Albion Works, Gainsborough, Lincolnshire. Aug. 29, 1930, No. 25797. [Class 87 (ii).] In apparatus for cutting blocks from a bar of plastic toffee or like material and wrapping up the severed blocks, the mechanism for feeding the bar to the cutter is carried by a bracket which is mounted, preferably on a pivot, for movement on the machine away from or towards the cutter, so that the latter is rendered accessible for cleansing &c. In the apparatus shown a bar 13 of toffee is fed by rollers 19, 20 to a knife 14, which may be of the kind described in Specification 351,993, and the blocks 12 cut off are pushed, each with its wrapper, into pockets on the periphery of a rotary wrapping-wheel 10. The feed rollers are mounted in a bracket 18 which can turn about a pivot pin 26 on the main frame 25 and is held in the operative position by a spring-pressed locking pin 33, which can be released by means of a handle 29. When the feed mechanism is in the operative position a lay-shaft 37 on the bracket is connected by a dog-clutch 38, 39, to a driving-shaft 36 on the main frame. The shaft 37 carries a spur wheel 40 which engages with a spur wheel 42 on the shaft of the roller 20. An endless chain 50 passes round sprockets 41, 44, 45 on the shaft 37 and the shafts of the rollers 19, 20, respectively, and also round an idler sprocket 47 by means of which its tension may be adjusted. When the bracket 18 is not in the operative position the feed rolls can be turned by means of a hand-wheel 52 on the shaft 37. The Provisional Specification states that the cutting- device may comprise a reciprocatable blade and a shear-plate.

Title: Improvements in variable speed gears
IPC: F16H29/00
Filed: 1920-09-08
Abstract: 161,502. Rawlings, F. Sept. 8, 1920. Variable-speed gearing. -A cam upon the driving-element a, is made variable in effect by varying the inclination of plates b, b<1> articulated together in pairs by pins c. The outer ends of the plates b<1> are supported on rods e fixed in the element a. The outer ends of the plates b are secured to rods d, which are adapted to be angularly displaced in unison to make the pins c approach and recede from the axis of a driven shaft j. Toggle-links n, q connect rods r carried by a loose ring k to rings m rotatively connected to the shaft j as by ratchet clutches u. Springs s tend to keep the toggles n, q bent to bring rollers t on their joint pins b in the path of the plates b. When the plates b are in circular form, no drive is transmitted. As the inclination of the plates b, b<1> is increased, the toggles open and close with increasing amplitude, and an increasing speed is transmitted to the shaft j. Finally, the rollers t become jammed between the plates b and rings m, solid driving resulting.

Title: Grinding machines
IPC: B24B49/00
Filed: 1964-06-26
Abstract: 1,074,207. Grinding. ULVSONDA VERKSTADER A.B. June 26, 1964 [June 27, 1963], No. 26511/64. Heading B3D. A grinding machine in which the workpiece is carried by a rotary chuck is controlled by means sensing the elastic deformation of the grinding wheel spindle, e.g. occurring when the wheel comes into contact with the workpiece. A workpiece 16 rotated by a chuck 20 is internally ground by a grinding wheel 14 which is axially reciprocated and moved radially. Pressurized gas, e.g. air, from a conduit 28 escapes from an orifice 42 in a member 24 closely surrounding the grinding wheel spindle 12, the member 24 being part of a member 22 secured to the wheelhead 10. At the beginning of a cycle, the grinding wheel is advanced rapidly towards the workpiece. When the grinding wheel contacts the workpiece, the tangential force (K2) deflects the spindle 12 towards the orifice 42, and the resultant pressure increase actuates a bellows 48, whereby an indicator 64 is operated and contacts 70, 72 are closed so transmitting a signal to the feed mechanism which automatically changes from rapid advance to feed rate. The member 24 has a second orifice (88) for the escape of air supplied from a conduit 74. The pressure in the conduit leading to the orifice (88) is communicated to a bellows 92 and the pressure in the conduit leading to the orifice 42 is communicated to a bellows 96. With a properly dressed wheel the deflection caused by the tangential force (K2) is equal or substantially so to that caused by the radial force (K1) and the pressures in the bellows 92, 96 remain balanced. If the grinding wheel requires dressing, force (K1) exceeds force (K2) so that the pressure in bellows 92 exceeds that in bellows 96 whereby an indicator 104 is operated and contacts 110, 112 are closed so transmitting a signal which automatically stops the feed; the grinding wheel is moved out of the workpiece and dressed. The deflection of the grinding wheel spindle 12 may be used to control the feed rate during grinding.
