Title: Improved method of cutting helicoidal surfaces on face toothed members
IPC: B23F15/06
Filed: 1955-04-19
Abstract: 775,716. Grinding. GLEASON WORKS. April 19, 1955 [April 19, 1954], No. 11296/55. Class 60 [Also in Groups XXII and XXIV] A method of simultaneously cutting helicoidal surfaces 35a, 35b of opposite hand on opposite sides of spaced teeth 22 of a face toothed member 20 consists in effecting a relative feed in a plane 37 common to the work axis 24 and the axis 27 of an annular cutter 26 presenting a tip edge cutting circle 41 to the work to cause the cutting circle to traverse both surfaces. simultaneously, the feed including an angular motion which maintains the cutting circle substantially tangent to the tangent. planes of the helicoidal surfaces at mid-points 43, 44 along the length of the teeth. The inside edges 25 of the cutter 26 cut opposite sides of spaced teeth and the work is indexed until all the teeth have been cut. The edges are inclined to the cutter axis so that the cutter teeth can be relieved axially. When the teetli are sharpened, therefore, the cutting edges recede axially (25<SP>1</SP>, Fig. 4) and a simple axial adjustment only of the cutter is necessary to restore the correct cutting relationship. The helicoidal tip surfaces, 35a, 35b of the teeth are cut by the rounded edges 38 and the edge 39 of the cutter 26. The teeth of the mating clutch member 21, Fig. 7, are cut by the outside edges 29 of a cutter 31. The teeth of the member 20 in axial cross-section thus have chamfered surfaces of convex curvatures and the teeth of the member 21 concaxe curvature; they will thus have substantially full contact at their centre portions with ease-off at each end. If the helicoids of the surface are not of constant lead, the profiles will be curved instead of straight as in Fig. 2. In a grinding machine, the member 20 is mounted for axial adjustment with an indexing mechanism 64 on a slide 62 adjustable vertically on a column 58. The column is adjustable about an axis 61 on a slide 56 adjustable on a base 55 in directions 57. The grinding wheel 28 is mounted in a housing 66 adjustable in directions 60 on a base 70 pivoted at 69. The base is carried on a slide 67 which is moved in directions 71 by a cam 72 acting through a lever 73. A coaxial cam 77 acts through a lever 79 and bevel gearing 82, 83 to swing the wheel about the pivot 69 to follow a path 85, Fig. 9, to cut the chamfers 35 and the sides of the teeth. Reference has been directed by the Comptroller to Specifications 572,612, 594,492 and 624,769

Title: Improvements in or relating to Tunnel Ovens.

IPC: F27B9/36
Filed: 1916-08-11
Abstract: 110,918. Dressler, C. Aug. 11, 1916. Tunnel kilns.-In a kiln or oven having longitudinally arranged combustion flues as described in Specifications 18114/10, 8228/12, 8505/13, and 18821/13, the high-temperature zone of the kiln is prolonged by introducing fuel and air into the combustion flues at different points along their length. The combustion points may be close together, so that a substantially uniform high temperature is maintained over a length of the kiln, or they may be spaced so that the goods pass successively through zones of high and lower temperatures. In one form, shown in Fig. 1, the combustion flue is divided longitudinally by a partition b, and the two chambers c, c<1> thus formed are supplied with gas through dampered ports d, d<1>, situated at different points in the length of the kiln, and with air either through separate inlets e, e<1>, or through a common inlet at the rear of the port d'. The products of combustion from the two chambers mix together in the undivided portion a' of the combustion flue. The combustion point of the inner of the two chambers c, c<1> is preferably nearer to the inlet end for the goods. The partition b may be flanged to provide strength, and the joint between it and the roof of the combustion flue may be made by sandy clay to allow for expansion. In a modification, the partition b extends only a short distance to the rear of the gas and air inlets d, e, and the chamber c is there closed by a transverse partition. In other constructions, one of the chambers is formed by an internal flue, or the two chambers may be end to end in the flue, and the gases from the rear chamber are led to the commmon portion a' by a bypass. In the construction shown in Fig. 8, gas is supplied through ports d to a number of separate combustion chambers, the roofs of which are arranged stepwise to allow air from the flue u to enter through ports e. The products of combustion pass into the flue through lateral openings v. In other forms, gas, or air, or both are admitted at different points along an undivided flue.

Filed: 1949-04-29
Abstract: 664,559. Knitting-machines. STIBBE & CO., Ltd., G., STIBBE, E. V., and BROWN, A. M. March 15, 1950 [April 29, 1949], No. 11437/49. Class 74 (ii). The pivoted trapper 5 of a trapping and severing device is held in its operative position by a lug 13 engaging the tail 28 of the trapper, the lug 13 being attached to a tubular member 14 which is actuated by mechanism operated by cams on the pattern drum and which through a compression spring 16 projects a cam 10 to effect the introduction of the welt instruments mounted in the dial of a circular machine to their advanced position. A certain amount of lost motion between the member 14 and the cam 10' enables the mechanism to be operated at required times by cams on the pattern drum to depress the member 14 and withdraw the lug 13 from engagement with the trapper 5, the trapper then only holding the yarns under its own weight and during which time a yarn can be withdrawn from operation and introduced beneath the trapper. After its introduction the yarn is additionally gripped by the lug 13 urging the trapper into its operative position after the mechanism has released the member 14 which is then urged upwardly by the spring 16.

Abstract: 474,370. Nonconducting coverings for heat and sound. RICHARDSON, G., and RICHARDSON, A. W. April 24, 1936, No. 11738. [Class 64 (ii)] Sheets of aluminium or other bright metal or alloy 0À05-0À15 mm. thick are pressed out to form cup-like projections on one or both sides, which projections bear on the surface to be insulated or on an intermediate sheet. The metal is preferably hardened by compression. The formation of cups is effected by first drawing the metal from a considerable area around the cup by a suitable tool and die, and then pressing out the cup. A number of such sheets 1, with cups 2 may be used, separated by plane sheets 4, Fig. 3, or in contact with one another, Fig. 6. In the latter case, the cups 3 may be half the height of the cups 2. The sheets may be wrapped around a curved surface. Alternatively, the sheet 1 may be provided with ribs 5, Fig. 11, having a minimum superficial area of crest, and substantially opposite to one another. Such sheets may be arranged in a box-like unit whose side walls 6 are bent over at 7. The ribs are cut near the wall 6, and the short length thus cut is flattened on to the sheet. The ribs on adjacent sheets are arranged at right-angles, or a plane sheet may be inserted between the ribbed sheets. The box-like units thus formed are arranged side-by-side on the surface to be insulated, and may be covered with bitumen or lacquer. The plane separating sheets 4 may be replaced by fibrous sound insulating sheets. Specifications 414,829 and 462,215, (the latter in the Provisional Specification), are referred to.
