Title: Improvements in or relating to controlling devices for ventilators, roof-lights and the like
IPC: E05F11/04
Filed: 1934-11-23
Abstract: 439,767. Stays; fanlight regulators. JONES, F. M., Lyndale, Wepre Drive, Connah's Quay, Flintshire. Nov. 23, 1934, Nos. 33666 and 34290. [Class 65 (i)] [See also Group X] In a fanlight stay and operating device of the kind comprising a cord passing over a pulley on the frame and downwards to a point on the sash or a part thereon, with a locking bar having pin and notch engagement with the frame, the cord, between the pulley and its free end, engages a projection or arm on or abutting against the locking bar to release the engagement of the bar. In the form shown, the locking bar 11 pivoted to the sash has a series of pins such as 13, 14 to engage with a bracket 20 on the frame ; the operating cord 23 passes over a pulley on the bracket 20 and a second pulley 27 at the lower end of the locking bar and is attached to an arm 25 pivoted to the bracket 20. The arm 25 carries a pin 28 which may be engaged by the cord 23 to press the arm against the locking bar and move the latter clear of the bracket 20 for lowering the sash. The bracket 20 has a tooth 20<a> by which the sash is supported in any open position by any pin such as 13 and a projection 20b by which further opening of the sash is prevented by engagement with any pin such as 14, so that the sash is positively locked in any position, including the closed. Tightening of the cord for opening the sash moves the bar sufficiently to free the pin 14 from projection 20b, the pins successively riding over the bracket 20 and snapping over the tooth 20<a> as the sash is opened. For closing, the bar must be moved farther, by means of the arm 25. In an alternative form, the locking bar has a number of teeth to engage over a pin on the frame, with one reversed tooth to engage under the pin to lock the sash closed, no locking being obtained in other positions. The arm 25 may be replaced by a projection on the locking bar, the end of the cord being then attached to the bracket 20. The free end of the cord may be attached to the end of the arm 25. In a modification, the pulley 27 is carried on a separate bar pivoted to the sash. Rollers may be provided on the engaging pins.

Abstract: 879,432. Positive clutches. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Oct. 21, 1958 [Feb. 11, 1958], No. 33683/58. Addition to 733,745. Class 80 (2). In the frictionally synchronized positive clutch 4, 11, of the parent Specification, wherein positive balk pegs 20 slidable radially between guides 19 on a synchronizing cone 14 which is freely rotatable in an inner member 8 splined on the driving shaft 1 ride radially outwards on circumferentially acting cam surfaces 22 under the pre-synchronous drag torque of the cone 14, to obstruct the axial movement of an abutment 24 in the positive clutch sleeve 11, the surfaces 22 are formed directly on the driving shaft 1 to allow the radial thickness of the member 8 to be small in relation to the diameter of the driving shaft and the pegs 20 to be guided over substantially the whole of the said thickness. Attainment of synchronization permits axial clutch engaging thrust to push the pegs 20 inwards, releasing the clutch sleeve 11 for positive engagement with the clutch teeth 4 of a freely mounted wheel 2. The free relative circumferential movement of the cone 14 is limited by the movement of its two diametrically opposite pairs of guides 19 within recesses 18 in the inner member 8. A spring ball detent locates the sleeve 11 with respect to the member 8 in the non-engaged position. The arrangement shown is a double clutch 4, 11 and 5, 11, with pairs of peg guides 19 on each synchronizing cone 14, 15.

Abstract: 1,057,157. Conveyers for mines. MASTABAR MINING EQUIPMENT CO. Ltd. Nov. 18, 1965, No. 33823/64. Heading B8A. Cam-plates 30 mounted on an articulated mine face conveyer 10 guide roof support units 18 during retraction of rams 26 such that the support units finish their movement normal to the line of the conveyer. Bending of the ram rods 28 due to the rams not being normal to the line of the conveyer is thus avoided and proper spacing of the units 18 is ensured. As each support unit is advanced, one of its front props 22 engages the adjacent cam 30 and the unit is laterally deflected. In Fig. 1 (not shown), two horizontal rams 58 operable independently of one another enable the support unit to be steered during advance. The cylinders of the rams are pivotally attached to a front shoe 46 for a single front prop 44, and each piston-rod 60 is attached to a cam-plate 50 which cooperates with a chamfered corner 48 of the shoe 46. In a modification, Fig. 2 (not shown), the rear ends of ram cylinders 64 are attached to the rear shoe 42 of the support unit. In Fig. 4 (not shown), the rams 72 are mounted within the rear shoe and are connected by link bars 74 to the cam-plates 50. Adjacent rams of adjacent support units are connected to the same cam-plate 70, thus reducing the number of cam-plates required, Fig. 3 (not shown).

Abstract: 342,016. Distributing music &c. WARWICK, A., Martins Bank Buildings, Deansgate, TAYLOR, J. A. A., 3, Fold Street, both in Bolton, and HOLMES, H. C., Kilnhouse Lane, St. Anne's-on-Sea. Nov. 7, 1929, No. 34025. [Class 40 (iv).] In a system for distributing electrical signals such as wireless programmes over lines from a main station B to a number of receiving stations A, means is provided at the main station for giving an alarm in response to the transmission of a fault signal from any receiving station, for identifying the faulty station, and for testing for the presence of leakage on the distribution lines. In the system shown, each receiving station is adapted to receive at will either a high-frequency or a low-frequency programme in accordance with the position of a switch 22. In order to signal the presence of a fault a subscriber at station A moves key 22 to the left and inserts a plug 5, thus completing a directcurrent loop over the line 1, 2 to operate a relay 15 which closes an alarm circuit. The main-station attendant then throws key 11 to the right and with keys 24,25 in positions 31, 32, measuring instruments 29, 30 which may be of different types give a reading which identifies the faulty station, each station having a characteristic resistance 33. When no fault signal is being transmitted and with keys 24, 25 in positions 31, 32, an indication is given of any leakage between lines 1 and 2, whilst with key 25 in position 34 and key 24 in position 31 or 35 the leakage between either line and earth is indicated. With a large number of distribution lines 1, 2 divided into groups, a separate alarm circuit is provided for each group and is connected to two bus-bars with which switches 11 one for each line in the group are normally in contact. When an alarm is given the calling line is identified by opening each switch 11 in the group in turn until the alarm ceases and the switch corresponding to the calling line is then thrown over to the other position to make contact with a further pair of bus-bars connected to an identifying and indicating apparatus such as C common to all the lines in all the groups. Specifications 319,984, 332,771, 333,460, 331,112, and 335,417, [all in Class 40 (v) Wireless signalling &c.], are referred to.

Title: Improvements in or relating to film driving mechanisms
IPC: G03B21/43
Filed: 1947-12-24
Abstract: 646,301. Feeding webs. KODAK, Ltd. Dec. 24, 1947, No. 34125. Convention date. Dec. 28, 1946. [Class 100 (i)] [Also in Group XX] A film feeding mechanism comprises a pair of rotatable shafts each carrying a gear for the simultaneous rotation of the shafts in opposite directions, a pulley on one shaft connected by a friction drive to a pulley on the spindle of a take-up reel, a friction clutch member connected by a positive drive to a spindle for a supply reel, and means for moving the clutch members into engagement with the gear carried by the other of said shafts for re-winding the film, said means being operated automatically by a torque introduced by the film to release the clutch member prior to the film being unduly stressed. In the machine shown, film is driven from a supply reel 29, on a spindle 27 projecting from a housing 11, around sprockets 20, 12 mounted respectively on shafts 18, 9 and on to a take-up reel 32 on a spindle 15 also journalled in housing 11. Shafts 18, 9 carry worm gears 17, 8, engaged by a worm 7 on a shaft 4 which is driven from an electric motor by a belt and pulley arrangement. Shaft 9 carries at one end a pulley 13, connected by a belt with a pulley 16 on the spindle 15 of the take-up reel 32. Rotatably mounted on the shaft 18 is a clutch member 24 in the form of a sprocket having a friction disc 23 attached thereto for engagement with one face of the gear 17 when a knob 21, threaded on shaft 18, is rotated clockwise as in Fig. 1. Sprocket 24 is chain connected with a sprocket 26 on the supply reel spindle 27. Hence, when it is necessary to re-wind the film direct from reel 32 on to reel 29, knob 21 is rotated so that clutch member 24 contacts gear 17 so that supply reel 29 is driven clockwise. During re-winding the rotation of take-up reel spindle 15 is in the opposite direction to that in which it is normally rotated by the gear 8 so that the belt slips over the pulleys 13, 15. When it is desired to drive the film from reel 29 and over the sprockets 20, 12 on to reel 32, clutch member is manually disengaged by anticlockwise rotation of knob 21 or such disengagement is caused automatically by the torque introduced by the film which tends to rotate the clutch member anticlockwise and thus loosen knob 21.
