Title: Improvements in and relating to variable velocity ratio gearing of the chain and sprocket type
IPC: F16H9/24
Filed: 1930-09-18
Abstract: 357,762. Expanding chain wheels. HEALEY, F. J., Britannia Works, Bassein Park Road, Shepherd's Bush, London. Sept. 18, 1930, No. 27957. [Class 80 (ii).] In variable velocity ratio gearing in which a chain is provided as the driving connection between expanding and contracting sprockets the teeth of the sprocket are provided on segments arranged in carrier members adapted for radial movement to vary the effective diameter and all the segments are secured in fixed angular relationship with one another and are mounted so as to be capable of limited radial movement independently of one another in their carrier members. As shown in Fig. 9, the teeth 36 in addition to their radial movement to expand or contract the sprocket are capable of limited radial movement by means of springs 33 bearing on the teeth body portions or segments 37 and also the teeth are arranged so that the angles between their planes and the radial median planes vary in the manner shown, in effect certain of the teeth are displaced relatively to their body portions. The teeth members 31, Fig. 3, are mounted on carrier members 28 having projections 26, 27 engaging in radial slots 24, 25 in discs 22, 23 and also projections 29, 30 engaging in scroll slots 18, 19 in discs 16, 17 the relative rotation between the sets of discs expanding or contracting the sprocket. The relative rotation of the discs is caused by relative rotation of shaft 7 and sleeves 10, 11 due to projections 44 on slidable members 64, 65, Figs. 2 and 3, engaging longitudinal and inclined slots. These members are operated by means of racks and pinions 68 .. 71 from toothed quadrants 72, 73 and a screwed shaft and handwheel 87. This hand-wheel simultaneously rocks an invariable sprocket 96 to take up slack in the chain and the sprocket 96 is rocked in an arcuate path. In the case of two coacting expanding sprockets gearing is provided so that one sprocket is expanded as the other is contracted. In another construction the teeth and carriers therefor 139, 139a, 138, 138a, Fig. 11, are expanded and contracted by means of conical members 147, 147a, 148, 148a which are caused to approach, or recede from, each other by rocker members 155, 156 and screwed shaft 169, 170. Specifications 162,384 and 176,511, [both in Class 80 (ii), Gearing, Variablespeed &c.], are referred to.

Abstract: 298,473. Rockwell, E. A. Oct 8, 1927, [Convention date]. Controlling different functions by same lever; controlling-apparatus, arrangements of hand, foot, and transmission gear in conjunction with; pedals, mounting.-A pedal is provided with means to operate alternately the accelerator and a brake, the accelerating movement being initially opposed by one spring, while, after a nredetermined distance, other opposing spring means come into action. The pedal 17 is carried by an arm 14 loosely mounted on a shaft 5 and a link 23 pivoted to an arm 29 on a shaft 30. When the toe of the pedal is depressed a spindle 15 on the arm 14 bears against and rocks a bent lever 9, 4 mounted on the shaft 5 and so actuates the accelerator or throttle shaft 1 through a. link 3. The bent lever 4 works between two stops to limit its movement and is controlled by a weak spring 6 and a stronger spring 8, the latter being inoperative during the initial movement of the lever to open the throttle. When the heel of the pedal is depressed the arm 29 is rotated and actuates the brake shaft 42 through links 34, 40 pivoted to arms 39<a>, 39b fixed to a sleeve loose on the clutch-operating shaft 36. The arms 14, 29 are connected together by a link 31 which forms two sets of toggle linkages with the arms so that the accelerator can only be operated when the brake is released and vice versa. The link 34 is adjustable in length to allow for adjustment of the toggle angles and also for adjustment of the brake arm 41. When the toe of the pedal is depressed the arm 29 is rocked slightly, but to avoid any operation of the brake a lost-motion connection 38 is provided between the link 34 and the arm 39<a>. The holes in the floor and through which the arm 14 and link 23 pass are respectively covered by a sliding fibre disc 20 held in place by a plate 21 and a sliding plate 24 held against the floorboard by a spring 25 in a housing 26. The link 23 is pressed against one side of a guide bracket 27 to prevent rattling. The lever arm 9 is connected through the lost-motion connection shown to a hand lever so that the throttle can be controlled either by hand or by foot.

A method and apparatus for producing continuous stationery wherein a paper web is drawn from a supply roll, allowed to fall in a festoon before passing through printing apparatus and then apparatus punching one or more longitudinal rows of holes in the web, is characterized in that drag is exerted on the web before it enters the printing apparatus and the web pulled through the printing and punching apparatus by an endless belt carrying pins engaging the holes punched therein. A plurality of printed webs and carbon webs may be collated prior to the punching apparatus to form continuous manifolding stationery. Each web is drawn from a supply roll by a continuously driven roller 21 and idle rollers 25, Fig. 4. The web falls in a festoon A3 before passing around guide-bars 31-33 to a printing unit 40. The bar 33 is tubular and supports collars 170, 171 guiding the web laterally, Fig. 13. The collar 171 is secured to an inner rod 178 by a screw 183 passing through a slot 182 in the tube. The rod 178 is slidable in the tube to allow for fine adjustment in the spacing of the collars. The bar 32 is carried by the collars 170, 171. The rod 178 and tube are rotatable in the sides of the machine frame whereby the angular position of the bar 32 relative to the bar 33 may be varied to alter the degree of wrap-round of the web, Fig. 17 (not shown). A brush 34 exerts drag on the web. A continuously driven roller 102 bears against a reel 100 of carbon paper. The carbon web falls in a loop 103 and then passes around guides 104-106 before being collated with the printed web 50. The printed webs and interleaved carbon webs are superimposed and provided with marginal perforations along one or both longitudinal edges by co-operating male and female dies 51, 53, Fig. 3. The superimposed webs are pulled through the printing units and punch by a or two spaced continuously driven endless pin belts 60. The or each belt carries a plurality of spaced L-shaped brackets 161 on which the pins 59 are mounted, Fig. 16. A bar 80 is pivotally mounted by links 83 above each belt 60. Each bar has a channel-shaped groove 81 which co-operates with the pins 59 when the bar is lowered by a handle 88. When lowered, the bar maintains the webs on the pins. The apparatus includes numbering apparatus 90, a file hole punching unit 91, a longitudinal tear - line perforator 92, a crimping unit 93, and cross perforator 94, Fig. 3. Each web may be perforated before entering its printing unit by perforating rollers 36, 37.
