Title: External honing tool
Inventor: CLIFTON FREDERICK HARRY
IPC: B24B33/08
Filed: 1961-05-26
Abstract: 982,811. Honing. RUSTON & HORNSBY Ltd. April 5, 1962 [May 26, 1961], No. 19024/61. Heading B3D. An external honing tool comprises a ring carrying a plurality of honing stones, a spider frame having legs removably attached to the ring, and having means for quick attachment to and removal from a conventional power-driven machine tool with a rotatable and reciprocable spindle, and means for simultaneously advancing some or all of said stones radially inward toward a workpiece, and subsequently simultaneously retracting said stones therefrom. A cylindrical portion of the boss, which is to be fitted with an oil seal, of a flywheel clamped to the bedplate of a vertical drilling machine, used for drilling and tapping, is externally honed by a honing tool comprising a spider frame 1 surmounted by a morse taper-type spigot 2 providing an unequal taper between the spigot and the drilling machine spindle socket so that a limited amount of float is allowed to the frame in a plane substantially normal to the axis of the spindle whereby the tool is self-centring round the workpiece. Equidistant legs 3A, 3B, 3C, having one or more bends are removably attached to a ring 4 divided into halves removably secured together. The ring carries a first set of three equidistant coarse grade stones 5 each held in a shoe 7 and a second set of three equidistant fine grade stones 6 each held in a shoe 7A. Each coarse stone 5 is adjacent a fine stone 6. The shoes 7, 7A are mounted for controlled radial movement toward and away from the workpiece. A manually operable knurled adjusting nut 8, in screwthreaded engagement with a parallel portion 9 of the spigot 2, acts on three pushrods 10 rotatably and axially movable in brackets 11, 12 attached to the legs 3A, 3B, 3C. Each pushrod can be rotated by means of knurled collar 13 to either of two positions, and is retained therein by a spring-loaded ball 14 engaging axial slots 14A in the pushrod. In one rotational position, the foot 15 of the pushrod co-operates with a cam 16 pivotally mounted on a plate 18 secured to the ring 4. The cam 16 has a projection 19 which advances or retracts the shoe 7 against spring loading. In the other rotational position the foot 15 of the pushrod co-operates with a second cam for advancing or retracting the shoe 7A. A knurled screw 21 in the head of each pushrod contacts the nut 8 through ball bearing 22 and provides individual length adjustment for each pushrod, e.g. to compensate for unequal wear of the stones. The screw 21 is locked by a nut 23. A spring 24 may be fitted between bracket 12 and collar 13. The ring may have two removable handles for manual operation without the spider frame. The legs of the spider frame may be adjustably articulated. The diameter of the workpiece may be ganged during housing, the machine being stopped automatically when the desired diameter is reached.

Bottling.-An improved apparatus for filling ball-stoppered bottles of the type in which the bottle is placed in a rotary holder attached to a rotary valve which allows the aerated liquid to enter the bottle and the air to escape, then cuts off first the air escape and then the liquid supply, finally again opening the air-escape outlet to allow of the seating of the ball, is combined with an aerating-apparatus which is also provided with a device for filling siphon-bottles. The aerating- device is of the type comprising a rotary agitator 4, here formed as a perforated disk, to the shaft of which is connected a pump for supplying liquid. The rotary valve comprises a hollow plug with two chambers 28, 29, passages from which lead to orifices in a seating 25 against which the neck of the bottle bears. When the valve is in the position shown, the compartment 28 is in communication with the atmosphere through a port 32 in the plug and corresponding port in the casing 19 in which the plug rotates, while the compartment 29 is in communication with the aerator through a port 31 and a pipe 10'. As the plug and bottle rotate, the ports 31, 32 are closed, the port 31 remaining open longer than the other as it occupies a larger portion of the circumference of the plug. On rotating further, a second port opposite to the port 32 is put in communication with the air when the bottle is neck downwards and the ball is resting on its seating. In a modification, the necessary opening and closing is effected by valves carried on the rotary holder and operated by cams on the casing of the rotary plug valve. In connexion with this form, a cage for the bottle, opened automatically when the filling is complete, is described. The device for filling siphon-bottles is shown in Fig. 3. It comprises a valve 12 normally held closed by a spring 18 and is provided on the upper surface with a rubber seating against which the nozzle of the siphon is held. The valve is opened by pressing the siphon-nozzle on it and the liquid enters the siphon.
