IPC: B24B19/16
Filed: 1947-06-23
Abstract: 638,563. Sharpening gramophone needles. E. M. G. HAND-MADE GRAMOPHONES, Ltd., and DAVEY, F. G. G. June 23, 1947, No. 16553. [Class 60] In a device for sharpening gramophone needles, such as thorns, and the like in which the rotation of the needle is derived from the rotation of the abrasive wheel by means of a pair of friction wheels, one of the friction wheels is cup-shaped and of rubber or rubber-like material, the curved surface of this wheel, or a part thereof, being arranged to engage the other friction wheel. The device comprises a channelshaped base 10 between the side walls of which is rockably mounted a support 12 carrying a bearing pin on which is removably mounted a unit comprising a screw chuck 14 and a cupshaped friction wheel 15, the central boss 25 of which is a tight fit on the knurled hub portion 26 of the unit. The base carries a second bearing pin 17 on which is mounted a hollow shaft 18 having fixedly mounted thereon a rubber sleeve 19 and an abrasive wheel 20. The chuck 14 is urged towards the abrasive wheel by a spring 21 and the wall of the friction wheel 15 engages the rubber sleeve 19 ; the latter may be rotated by drawing a finger over it, or it may be rotated by the turntable 24, the base 10 of the device being provided on its underside with a cork sheet 11 to rest on the gramophone top.

Title: Holding device for spare wheels on motor-cars
IPC: B60R25/00
Filed: 1929-05-29
Abstract: 326,713. B�ddecker, L. May 29, 1929. Securing spare wheels on vehicles.-In spare wheel holders of the type in which the wheel is secured on a fixed bolt 2 by a nut 6, backward rotation of which to release the wheel is prevented by a locking-device, the latter consists of a lock inserted in the nut and adapted to control a sliding latch 17 normally engaging an aperture 23 in a washer 5, which is non-rotatably mounted on the bolt 2, as by a key 4 engaging a groove 3. The lock comprises a cylindrical casing 7 having lateral cylindrical extensions 8, 9, in one of which tumbler pins 10 are mounted. A rotatable barrel 12 is provided with an extension 11, and is held in position by a slotted disc 14 engaging an annular groove 13. A bush 16 is fixed in the central part 15 of the lock hole drilled in the nut, and contains the slidable and rotatable latch 17 fitted with a spring 20 and transverse pins 18 engaging a slot 19 in the extension 11. When the barrel 12 is rotated by means of a key, the latch 17 is rotated through the coupling 18, 19, and a pin 21 on the latch slides along an inclined edge 22 cut in the bush 16, thus retracting the latch from the aperture 23, and permitting unscrewing of the nut. In the unlocked position, the key cannot be removed from the lock. Otherforms of locks of similar type are described, having special means for permitting withdrawal of the key at certain positions.

Abstract: 421,064. Filling valve-bags. MIDDELBOE, K., 14, Thorvaldsensvej, Frederiksberg, near Copenhagen. June 13, 1933, No. 16892. [Class 94 (i)] In apparatus for filling valve-bags with granular or pulverulent material, the feed mechanism for conveying the bags one at a time to the filling spout includes means for opening the valve of each bag before it passes over the spout. Such means may comprise needles adapted to enter the valve walls, a sucker engaging one wall of the valve, or a jet of compressed air. The bags are delivered in succession to a container 6 from a vertical stack 2, Fig. 1 by a conveyer 4 provided with catches 3 or from a horizontal stack 2<b>, Fig. 2 by a pusher 20 on a screw-threaded shaft 21. The carriage 13 which moves on rails 11 is provided with jaws 14 which are moved inwardly to grip the bag in the container 6 by the engagement of rollers 24 with cam tracks 25. On further movement of the carriage, the needles 16 are engaged by rollers 17 so that the points of the needles are pressed slightly into the valve of the bag and then spring apart again, pulling the walls of the valve with them, as in Fig. 5.

Abstract: 473,915. Retarding action of switches. GENERAL ELECTRIC CO., Ltd., PUCKETTE, C. C., and WARRINGTON, A. June 19, 1936, No. 17058. [Class 38 (v)] [Also in Groups XXXIX and XXVI] Relates to a telephone instrument incorporating a switch for closing the line circuit when the receiver is removed from its cradle and in which delay mechanism is incorporated for retarding the contact-closing movement of an actuating arm, attached to the cradle, to prevent the accidental transmission of impulses to the exchange or the fraudulent use of the cradle member to operate automatic selecting apparatus. The cradle 1 for the handset has a plunger 3 mounted in a collar 2 on a frame member 6 and connected to an insulating tip 5 engaging the contacts 7. An L-shaped member 11 connected to the plunger 3 by a nut 14 carries a pin 16 engaging in a slot 17 in a toothed sector 12 meshing with a pinion 18. A spur wheel 19 is coupled to the pinion 18 by a one-way spring clutch and drives a worm 20 on the shaft of which is mounted a centrifugal governor 25 which rotates in a cup-shaped casing. On the removal of the handset the cradle is moved upwardly by a spring 24 and the spur wheel 19 which is coupled to the pinion 18 drives the centrifugal governor 25, thereby limiting the rate at which the stem rises and applying a frictional braking action if the stem rises too rapidly.

Cracked portions of casting moulds of cast or hematite iron are repaired by removing the metal around the cracks to form a cavity 2, Fig. 2, filling the cavity with spaced cast rods 3 of a diameter corresponding to the depth of the cavity and filling in by welding. The rods 3 are secured by root welds 4, 5 and the corner of the cavity is also filled by a root weld 4. Welds 6 are formed to joint the root welds. Alternate spaces 7, 9, 11 are then filled with weld metal and finally the remaining spaces 8, 10 are welded. Where a mould has a crack 12, Fig. 3, passing completely through the wall, the lower surface of the mould and the inside around the crack are chiselled out to a depth equal to about one-third of the thickness of the wall of the mould and the cavity is filled as described above. The end of the crack is stopped by drilling a hole 18 and a patch 17 is secured by bolts. The openings in the patch 17 around the head of the bolts may be made large and filled in by welding the shrinking occurring on cooling tending to pull the patch 7 tightly on to the surface of the mould. Where the cracking is worst an auxiliary patch 19 may be secured by edge welds and by welds in slots 20. A patch having a tapered section may be used. Where as shown in Fig. 6, the crack extends through a corner of the mould, a plurality of patches 17<SP>1</SP>, 17<SP>11</SP> are used, joined by plates 19<SP>1</SP> welded in position.

Class 142(2) The shed is initiated by a small displacement of healds and completed by wedge elements on the weft carrier. The healds 5 are carried in a ring A and are actuated by selector discs 10, Fig. 2, or by star wheels, 10, Fig. 6. They may terminate in elongated loops M, as shown, or in thin blades in which latter case, the warps pass between the blades of. adjacent healds. The weft carrier C is circulated through the shed and supported by a magnetic roller 24. It includes rollers 34, 35 which roll on the inner warp sheet and are geared to rollers 52, 53 which rotate in the opposite direction to the rollers 34, 35 and drive belts 54, 55. The surface speed of these belts relative to the warps is zero and the outer partially opened warp sheet is engaged by wedge elements 60, 60<SP>1</SP> and passes round the belts 54, 55 to complete the shed. The weft is laid by a needle 43. A feeler 16 is carried by the selector mechanism and rolls in advance of it on the inner ends of the healds, to detect broken warps and complete an electrical circuit to stop the loom. The lower roller 35 and belt 55 may be dispensed with in an alternative embodiment (not shown).
