Abstract: 306,065. British United Shoe Machinery Co., Ltd., Woodcock, R. B., and Barclay, W. R. Nov. 15, 1927. Addition to 285,102. Polishing and waxing machines. - In machines for finishing boot or shoe bottoms, as described in the parent Specification, means are incorporated to facilitate the renewal of worn - out covers of the waxapplying and 'bottomburnishing rolls. The positively - driven concave wax-applying roll 1, having a yielding covering, is indirectly heated by the casing 2, extending round the back of the roll, and by the presser-roll 3. The heating means may be steam, hot oil, or electricity. The presser-roll 3 is convex in form and serves to restore the shape of the applying roll, when distorted in operation. The shaft 4 is mounted eccentrically at 6 so that the roll 1 may be moved in relation to the presser-roll 3 which is carried by a slide 10, locked by a screw 11. To the left of the roll 1 is mounted a bottom-burnishing or polishing roll 12 and a conical waist-burnishing roll 13 on opposite ends of a shaft 14, coaxial with the shaft 4 and driven by a pulley 16. The shaft 14 is carried in a bracket 17 pivoted at 18 to the machine table, so that the bracket 17 may be rotated downwards about the pivot 18, to bring the rolls 12 and 13 into a position clear of the machine, to facilitate renewal of the roller coverings. A rotary brush 29 is supported on a bracket 31 so that its working face and those of the rolls 12 and 13 are in the same vertical plane. A beltdriven rotary pad 33 for burnishing the waist of the sole, and similar in construction to that described in the parent Specification, is mounted on a shaft 34 carried by a sliding bracket 36 clamped by a screw 38. The cover of the pad. may be applied bv a device of the kind described in Specification 255,549, [Class 60, Grinding or abrading &c.], mounted in a support fixed to the machine-bed 9, within convenient reach of the operator.

Abstract: 1336925 Friction clutches; change speed gearing BORG-WARNER CORP 30 June 1971 [17 July 1970] 30660/71 Headings F2C and F2D A clutch 41 is engaged by a diaphragm spring 61 acting on an operating member 51, and is disengaged by means of flyweights 81 normally biased to an inner orbit by a second diaphragm spring 71 but which move out when the centrifugal force on them exceeds the resistance of the spring 71, and as a result of the increasing centrifugal force as the weights 81 move out, the construction of spring 71 which causes its resisting force to fall as the weights move out, and the construction of spring 61 which exerts a force such that the centrifugal force on the weights exceeds the sum of the resisting forces of both springs when lost motion 87 has been taken up by the initial movement of the weights 81, the clutch is disengaged completely at the same speed as that at which the weights initially move. The clutch 41 becomes re-engaged at a lower speed than that at which it is disengaged. The clutch is shown as part of a two speed drive for accessories from an engine output shaft 11, a pulley 13 being mounted on an overrunning clutch 32 on the shaft and the pulley 12 being mounted on the centrifugally operated clutch 41. At low speeds, the clutch 41 being engaged, the pulley 12 drives a pulley 16 attached to a pulley 17 which in turn drives pulley 13 faster than shaft 11, and it overruns, at higher speeds, the clutch 41 becoming disengaged, and the pulley 13 driving. The dimensions are such that in the latter condition the pulleys 16 and 17 (on a shaft 14) run slower relative to shaft 11 than with the clutch 41 engaged.

[Class 97 (i).] An intermittently rotated film feed roller is operated by a rotary member having annularly arranged means for engagement with one or more driving pins or the like which are intermittently moved radially of the member to engage and disengage it, and are intermittently oscillated about its centre to rotate it ; means for holding the rotary member stationary between its rotations may be provided, and the feed roller may itself form the rotary member. As shown, a feed roller 1 having sprocket teeth 2 constitutes the rotary member, and is provided with rings of perforations 12, 24. The perforations 12 are intermittently engaged by driving a pin 11 on a lever 10 riding on the shaft 3 of the roller and embracing a cam 7 on a driving shaft 5. The cam oscillates the lever about the shaft 3, to feed the roller, and eccentrically carries a pin 8 engaging an arcuate slot 22 in a control rod 20 riding on the shaft 3. The control rod is constrained so as to be moved axially by the action of the pin 8, and a pin 19, carried by the control rod, and engaging an arcuate slot 18 in the lever 10, moves the lever axially to engage and disengage the pin 11 and the perforations 12. The end of the control rod is formed as an arresting pin 23 to engage the perforations 24 and hold the roller between the feed movements ; constraint is applied to the control rod by a guide 25 engaging the pin 23. A spring 16 holds the cam and lever in engagement. In a modification, the roller 1 may be coupled to a rotary member engaged by the pins 11, 23.
