Title: Improvements in Gear Trains.
Inventor: PARSONS CHARLES ALGERNON
IPC: F16H1/20
Filed: 1917-06-11
Abstract: 116,531. Parsons, Sir C. A., Cook, S. S., and Douglas, L. M. June 11, 1017. Toothed gearing.-To prevent the deflexion 'of an intermediate shatt used in double helical reduction gearing by the reactions between the gear teeth, the shaft is so placed with respect to the driving and driven shafts that the reactions between the different sets of gear teeth act in parallel lines. This condition is fulfilled by mahing the angle between the common radial lines of the shafts a, d and d, g equtd to the sum of the angles a<1>, a<2> representing the slope of the gear teeth, that is the angles a , Fig. 2, between the common radius r of two wheels and the common tangent t of the tooth surfaces. Modifications applied to double and to triple reduction gearing are described in which the shafts are so arranged that the forces acting on the intermediate shafts are all vertical. In another modification, two driving pinions h engage the wheel c on the intermediate shaft d, and are so placed that the resultant of the forces between the teeth is in a line parallel to the line of action between the teeth of the wheels e, f.

Abstract: 1,087,170. Animal feeding appliances. W. C REDDEN. March 1, 1966 [Oct. 11, 1965], No. 8823/66. Heading A1M. [Also in Division B8] An endless conveyer comprises a pair of spaced chains 46 pivotally supporting a plurality of gravity pivoted open ended troughs 52 supported at their free end (57) by overlapping the preceding trough and successively discharged by the movement relative thereto of a carriage 60 supporting the leading trough. The carriage 60 is mounted to run on rails 62 in a plane parallel to that of the conveyer and is moved in the direction of the conveyer by the engagement between an upstanding peg 96 attached to a friction braked chain 76 mounted on said carriage and the spindles 54, 56 mounting the troughs 52 on the chains 46. The discharge is achieved by the actuation of an electrically driven winch 104 connected to the carriage 60 by a rope 106 to overcome the friction braked chain 76 and move the carriage 60 in a direction opposite to that of the conveyer to permit the carriage supported trough to adopt a discharge position. In turn the succeeding troughs are successively supported and then discharged by the movement of the carriage. The amount and position of animal feed discharged into a feeding trough 12 can therefore be controlled by controlling the movement of the carriage. The carriage supports the troughs by means of a rubber tyred wheel 100 and may have a pivotable flap 12 mounted below and in front of the wheel to direct the discharged material to each side of a feeding trough divide (116). The lower run of the conveyer chains is supported by longitudinally extending beams 50 and the troughs in the upper run of the conveyer are guided by a substantially horizontal frame 38.

Filed: 1969-02-19
Abstract: 1,244,405. Separating sheets. G. SCHICK. 19 Feb., 1969 [20 Feb., 1968], No. 8868/69. Heading B8R. Sheets are separated from the top of a stack by rollers which are traversed across the upper surface of the stack to cause the upper sheets to overlap one another, the rollers being rotatable about parallel spaced-apart axes carried on an endless roller chain. In one embodiment, Fig. 1, a housing 1 partially encloses a chain 2 over a stack 4 of sheets; the chain 2 is a twin roller chain having common rivets spacing them apart, every second rivet supporting a barrel-shaped freely-rotatable roller 3; the chain extends over two chain wheels 6, 7, one of which is driven so that the rollers 3 traverse across the stack 4 and feed sheets in overlapping fashion to further feed rollers (not shown). The housing 1 may be vertically movable and can be fastened to a support arm actuating limit switches controlling the tablelifting mechanism. Guide rails 8 press the rollers 3 into contact with the stack along the lower run of the chain so that the latter adopts a rectilinear or slightly curvilinear configuration bowed towards the stack. An alternative embodiment, Fig. 2 (not shown), includes an endless belt (9) acting from the inside of the separating device and forming the drive for the rollers 3, the endless belt being trained around pulleys (10, 11) coaxial with chain wheels 6, 7. In this case, the rivets of the chain serve to keep the rollers 3 parallel in their traverse across the stack. A resilient rail (13) presses the rollers 3 in their upper run against belt 9 and imposes a drive on chain 2 at half the speed of the belt. The rollers 3 may be replaced by narrow discs or diametrically-bored balls. Movement of the sheets under the action of rollers 3 is also ensured in both embodiments by the weight of the housing; in the second embodiment, the rail 13 ensures that the rollers turn continuously even if the housing is lifted off the stack.
