Title: Improvements in or relating to the roughing of surfaces of sheet material
IPC: C14B1/48
Filed: 1935-12-20
Abstract: 467,591. Sole &c. roughing-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., RICKS, F., and PRATT, J. W. Dec. 20, 1935, No. 35275. [Class 31 (i)] In a machine adapted for roughing shoe soles marginally by means of a tool comprising a rotary spindle having a number of pointed spikes or teeth projecting axially from one end thereof, means being provided to feed workpieces past the tool, (a) the soles are fed intermittently and are supported by a plurality of independently yielding rolls, (b) a guard plate which limits the depth of roughing has its workengaging face inclined to allow increased roughing as the soles pass across the roughing zone, (c) a rotary brush operates on the soles during their travel past the tool, (d) means are provided to allow the tool to be moved manually without disturbing its carriage by bearings in which it rotates to facilitate change of its roughing parts. Soles held against a plate 42 by independently spring-pressed frusto-conical rolls 43, 44 are fed to a roughing tool 20 by a feed point 32 moved in an elliptical path by an eccentric 27 and a semicircular member 34 pivoted at 33 to the machine frame 10 ; the feed point can be moved to an inoperative position to provide access to the roughing tool by engaging the pin 33 in a hole 35. The rolls 43, 44 are carried by levers 45, 46 provided respectively with a pivot sleeve 47 and pin 48 bearing in the frame 10 and controlled by adjustable springs 50, 49 and stops 52, 51. A side gauge 62 is also provided. The tool 20 is mounted on a hollow shaft 18 in a bracket 14 which is adjustable vertically by a screw 63 to vary the projection of the tool spikes below the plate 42: the projection of the spikes from the tool body 20 is also adjustable by screwing the body 20 on to the shaft 18. The underside of the plate 42 slopes upwardly from rear to front and right to left, Fig. 1, to cause greater roughing action on the work as it passes from the rolls 43, 44. A plate 38 can be depressed by a knob 40 against a spring 39 to remove loose fibres from the tool spikes. The tool can be raised clear of the work bv lifting the bracket 14 by a hand lever 54, the bracket being locked in operative or inoperative position by a lever 56. The work is preliminarily roughed by a rotary wire brush 64 carried by a housing 67 supported by a dovetail guide 68 on a lever 69 which is adjustable by screws 72, 74. Dust from the roughing operation is removed through apertures 82, 84, in a duct 80 to which suction is applied. The work may be cleaned after being roughed by a brush 114 mounted on the column of the main machine. The brush is carried by pivoted arms 108, and projects through an opening in a plate 105, being adjustable by a screw 116. Feed rolls 130, 132 mounted on pivoted arms 126, 128 project through the plate 105 and are adjustable by screws 133. A presser plate 136 carried by pivoted arms 138, 139 and controlled by a spring 142 holds the work up to the feed rolls and brush.

Title: Clutch actuating means
IPC: F16D48/02
Filed: 1974-08-13
Abstract: 1481835 Clutch control ARDIE-WERK GmbH 13 Aug 1974 [21 Aug 1973] 35539/74 Heading F2L In an electro-hydraulic control system for a motor vehicle friction clutch wherein a clutch actuating hydraulic motor 1 is supplied with pressure liquid from a pump 4 through a valve 6 controlled by an electric or electronic control system 7, a viscosity independent flow regulator 12 is associated with the control valve 6 and controls the flow of liquid to or from the motor 1. With the system conditioned as shown the clutch is engaged and the hydraulic motor 1 is vented through a line 8, a viscosity-independent flow regulator 14, the control valve 6 and the flow regulator 12. For clutch disengagement the electric control 7 changes over an electromagnetically operated valve 17 which supplies pressure liquid from the pump 4 to the control valve 6. Changeover of the control valve 6 supplies pressure liquid from the pump 4 through the flow regulator 14 to the hydraulic motor 1 whereupon the pistons 23, 26 thereof are moved right for clutch disengagement. A switch 32 actuated by a rod 25 fast with the piston 23 signals full clutch disengagement to the control 7. For clutch reengagement the control 7 initially de-energizes the valve 17 which is returned to the position shown to vent the line 20 to the control valve 6 which also returns to the position shown. The hydraulic motor 1 is thus vented through the line 8, flow regulator 14, control valve 6 and flow regulator 12 which progressively throttles the exhaust from the motor 1 in dependence upon the position of the piston 23 to which it is mechanically connected. A spring 27 acts between the two pistons 23, 24 of the hydraulic motor 1 and the space therebetween is filled with liquid. Leakage from the space between the piston is made up by flow through a very small orifice in a line 28 from the line 8. In Fig. 2 (not shown) the control valve and viscosity independent flow regulator are combined as a single servo controlled valve which, in one end position, supplies pressure liquid to the hydraulic motor 1, in the other end position exhausts the hydraulic motor 1 at a predetermined rate and at intermediate positions progressively throttles the exhaust from the hydraulic motor 1. During clutch engagement the servo valve is moved by the electric control 7 in dependence upon the position of the piston 23 of the hydraulic motor to progressively throttle the exhaust from the motor during final clutch engagement. Alternatively the valve may be moved by the control 7 in dependence upon the difference between clutch input and output speeds.

Title: Improvements relating to the synchronising of printing telegraph installations
IPC: H04L21/00
Filed: 1934-12-11
Abstract: 431,996. Copying - telegraphs. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Dec. 11, 1934, No. 35555. Convention date, Dec. 11, 1933. [Class 40 (iii)] In a telegraph of the Hell type, the rotation of the spiral at the receiver is stopped at the end of each scanning-line and released by a synchronizing-signal. Thus the rotating spiral 3 (against which the straight edge 6 is intermittently pressed so that the carbon 5 may be caused to mark the paper strip 4 with vertical lines which build up the received characters) is arrested by a detent 10 at the end of each scanning-line and released by a synchronizing impulse applied to the magnet 8 at the beginning of each scanning-line. The start impulse may be sent by projections added to the transmitter cams for that purpose, or by a separate cam. In a modification the spiral 3 may be stopped at the end of each scanning-line by short-circuiting a motor-regulating resistance, the short-circuit being completed through two contacts, one controlled by the printing cylinder bearing the spiral 3, and the other by the magnet 8.
