Title: Improvements in mechanical and hydraulic variable-speed gear arrangements
IPC: F16H47/06
Filed: 1936-11-06
Abstract: 484,584. Mechanical and hydraulic variable-speed gear arrangements. KLEIN, SCHANZLIN, & BECKER AKT.-GES. Nov. 6, 1936, No. 30279. Convention date, Nov. 6, 1935. [Class 80 (ii)] [Also in Group XXIX] To obtain more favourable running conditions from hydraulic gearing H, (not described), particularly of the F÷ttinger type and including for instance one or more converters and one or more clutches, the gear H is driven from the engine M through a mechanical changespeed gear E which yields an overdrive for increasing the speed of the hydraulic gear above that of the engine. Graphs are given showing how it is possible to make the curve of tractive effort against running speed more nearly approach the ideal hyperbola by introducing the overdrive at normal running speed with the hydraulic gear in clutch operation. The driven device R is a vehicle axle. In Fig. 1, the mechanical change-speed gear E yields direct-drive through a clutch 1 and overdrive through a clutch 5. In Fig. 3 (not shown), both speeds are overdrives but of different value, driving and driven shafts being parallel. In Fig. 4 (not shown), an additional simple mechanical two-speed reduction and reversing gear is arranged between the output of the hydraulic gear H and the load K, the output shaft having a brake to facilitate change in the mechanical gear. Fig. 5 includes an allmechanical byepass for the hydraulic gear H and comprises a driving shaft 14 extended at 31 so as to provide means for driving the input 20 of the hydraulic gear from its rear end at a higher speed, through a clutch 32, wheels 24, 23 and clutch 33, than when it is driven from its forward end through a clutch 19 and wheels 17, 18. The output shaft 21 of the hydraulic gear passes a direct drive to the load K when a double clutch 29 on the shaft 21 is clutched to a fast wheel 27 on the load-shaft K, and passes a reduced or reversed drive thereto through the clutch 29, wheels 23, 24, countershaft 25 and wheels 26, 27, with or without a reverse idler 30. By clutching together the shaft 31 and countershaft 25 at 32, all the other clutches being disengaged, an all-mechanical reduced or reverse drive can be obtained through the wheels 26, 27 and idler 30. The output shaft 21 of the hydraulic gear has a brake B at its forward end to facilitate change in the mechanical gearing. A further modification, Fig. 7 (not shown), includes two engines driving a common shaft through oneway clutches and bevel gearing, the shaft being connected through high- or low-speed bevel gearing to a hydraulic gear, driving the load. The mechanical change-speed gears may be planetary or frictional.

Title: Die accelerator and control mechanism
IPC: B23D25/04
Filed: 1961-08-22
Abstract: 986,575. Shearing. E. R. BODNAR. Aug. 22, 1961 [June 30, 1960], No. 30295/61. Heading B3W. A flying shear for sheet metal comprises a measuring device for determining the length of sheet metal passing, and delivering a signal to an impulse generator which produces an electrical impulse, when a predetermined length of metal has passed, to a trigger mechanism which actuates means for accelerating the shear blades from a rest position up to the speed of the moving sheet, means responsive to the movement of said shear blades to actuate the press operating mechanism and mechanism to return the blades to the rest position. A pair of reciprocating shear blades 10, 11 are mounted on platens 14, 15, which are fastened to slides 18, 19 which run on guide rails 20, 21. The rails 21 are fastened to the bed of the machine and the rails 20 to the movable plate 23 which is mounted on adjustable pillars 25 sliding in collars 26. A constant speed electric motor 27 operates the plate 23 through any suitable mechanism and an air clutch 29 controlled by a valve 30, and a brake mechanism 33 controlled by an air valve 34 is provided. The platens 14, 15 are reciprocated parallel to the direction of travel of the sheet metal by a rod 35 which has rack teeth 39 and is driven in the forward direction by a pinion 41 which is in turn driven by a constant speed motor 44 through a variable speed drive 43 and an air operated clutch 42. The return movement of the platens is achieved by an air cylinder 48 controlled by a valve 50. The length of sheet metal passing is measured by a toothed wheel 53 which drives a signal generator 55. A guide wheel 56 is spring loaded on to the underside of the sheet. Signals from the generator 55 pass to a computer in a console 58 which delivers an impulse when a predetermined number of signals have been received. The impulse operates an electrical relay 59 associated with air valve 46 which engages the clutch 42 and transmits the drive to the pinion 41. The platens 14, 15 accelerate rapidly to the speed of the sheet metal and move forward until an arm 61 of a switch 60 fastened to the frame is struck by the platen 15, and a relay 62 operates to actuate the valve 30 controlling clutch 29 so that the plate 23 moves down and the sheet metal 12 is sheared. During the following upward movement of the plate 23 a cam 65 on the operating shaft actuates a switch 63 and hence air valve 50 so that the piston 49 of the cylinder 48 moves rearwardly. When the plate 23 reaches its highest point a cam 69 actuates a switch 67 and through a relay 70 and air valve 34 applies the brake 33.
