Title: Improvements in brushes for electric commutators, principally the collectors for electric machines
IPC: H01R39/26
Filed: 1929-06-13
Abstract: 340,975. Brushes and brush-holders. DRAKE DEL CASTILIO, (nÚe Schrambach), M. J. Y., 240 bis, Boulevard Jean Jaures, Billancourt, France. June 13,1929, No. 18242. Convention date, Dec. 6, 1928. Void [Published under Sect. 91 of the Acts]. [Class 35.] A brush for dynamoelectric machines-or the like is of such a crosssection and is so mounted with regard to the commutator that the brush contact area on a given segment first progressively increases and then progressively decreases as the commutator rotates. Sparking is thereby reduced and a further reduction may be obtained by mounting the brush with its longitudinal axis not normal to the contact area so that the movement of the commutator tends to hold the brush in firm contact with its guide. Fig. 1 shows in transverse section a rectangular brush 1 mounted with one of the diagonals A B of its section parallel with the direction of travel F of the commutator segments 2. A brush 1 of rectangular section is shown in Fig. 2 with its axis 1a inclined to the normal C D to the commutator at the central point of contact. As a result, with the direction of rotation shown, the brush is held against the upper front and lower rear inner surfaces of the brush box 3 and chattering is reduced.

Abstract: 403,717. Tyre - grooving machines. SCRUBY, H. F., 837, West Washington Boulevard, Los Angeles, U.S.A. June 29, 1932, No. 18350. [Class 31 (i).] A machine for circumferentially grooving the tread surface of an elastic tyre D, Fig. 1, comprises supports B, C and C for rotating the tyre about its axis and a groove cutter 25 for engaging the tyre surface as it is revolved. A base A mounted on legs 10 carries drive rollers B, C supporting and driving the tyre. The rollers are driven by chain sprockets rotated by a handle 16. Idle rollers E, F assist in causing the tyre to revolve evenly. The roller E is journalled on an adjustable shaft 18 so that different tyres can be accommodated. The roller F is journalled on a shaft 21 carried in sliding blocks 22 running on rods 24 &c. Side guides G, H, I are arranged around the sides of the tyre. The groove cutter 25 is carried in a frame movable to and from the tyre and also transversely by a slide 26 so as to cut parallel grooves. The slide may be traversed by a screw passing through a lug 28, Fig. 2, the slide 26 has a sleeve 30 in which the cutter carrier 31 is slidable longitudinally. In the inner end of this tube an adjusting stem 32 is threaded and revolved by handle 33. An adjustable shaft 34 is slidable in the tube 31 and carries the cutter blade 25 and is swiveled to the inner end of the adjusting stem 32. Normally this tube 31 is pressed outwards by a compression spring 35. A bolt 36 entering slots 37 in the tube 31 and shaft 34 prevents the tube 30 and shaft 34 from turning and permits longitudinal movement. The cutting blade 25 is semi-circular in shape but may be of any shape desired to cut the groove in the tyre and is held upwardly and forwardly inclined to cut the groove in the tyre by bolt 38, Fig. 3, or other means. A pair of idle gauge rollers 39 define an even depth of cut and the spring 35 compensates for inequalities in the tyre surface. To withdraw the cutter and gauge rollers, a lever handle 40, Fig. 2, pivoted at 40<1> carried by the sleeve 30 and its median portion, is pivoted to the outer end of an offset pull rod 41 freely attached to the tube 31 by a pin 42. The pull rod 41 is so shaped that one end lodges behind the support 401 and holds the cutter and rollers in an inactive position. When the handle 40 is reversed, the pull rod 41, tube 31, cutter 25 and rollers 39 are released and function with the tread surface of the tyre. The tyre may be inflated and mounted on a wheel to revolve against the cutter, but when demounted as in Fig. 1, a rest is provided such as an idle wheel K<1> journalled on a shaft 51 with guide blocks 52 sliding freely on arms 53 against compression springs 54.

Title: Improvements in or relating to axial flow turbines or compressors
Inventor: SHORTHOSE NORMAN LESLIE
IPC: F01D5/30
Filed: 1959-05-30
Abstract: 875,412. Turbine blade fixings. BRISTOL SIDDELEY ENGINES Ltd. May 30, 1960 [May 30, 1959], No. 18514/59. Class 110 (3). The invention relates to axial flow turbines or compressors of the kind in which the rotor disc 12 or blade supporting member of the stator has undercut circumferentially extending serrations 13 arranged to co-operate with complementary undercut serrations in the roots of blades A, B, C carried thereby, the serrations in the rotor disc or stator member being interrupted by a radially extending gap 14 forming a gate providing radial access for the blades to and from the circumferentially extending serrations. There are three types of blades A, B, C provided. The blades A are positioned in abutment with one another around most of the periphery of the rotor and the blades B, C are arranged in pairs around the remainder of the periphery in the vicinity of the gate. The circumferential width of the gate 14 is smaller than the circumferential width of each blade root and the serrations of each root are relieved at 16, 17 to enable the blade to be inserted or removed radially through the gate 14. The roots of the blades A, C are of the same circumferential width and those of the blades B of thinner circumferential width. This enables the blades to be moved along the serrations so as to leave sufficient room for the insertion or removal of the last blades C10, Fig. 4, through the gate. The circumferential spaces between the blades B9, C10, after the insertion of the last blade, is reduced by spacing the blades around the disc between the blades A0, A11 and inserting U-shaped spacers 18, 18<SP>1</SP>. The circumferential width of a spacer is such that together with a blade root B it equals the circumferential width of a blade A or C. The inner edges of the limbs of the U are arranged to embrace the serrations 13 so that the spacers are located axially but are not undercut so that the spacers may be withdrawn or inserted radially without having to be moved to the gate 14. Axially extending slots 19, 19<SP>1</SP> cut in the periphery rotor are engaged by the spacers to prevent circumferential movement of the spacers. The spacers 18, 18<SP>1</SP> are prevented from moving radially outwards by locking members 21 of substantially T-section. The cross limbs of each T engage slots 22, 23 in the adjacent faces of the spaced roots B and C. One of the blade roots adjacent each locking member 21 has a depression 24 into which the thinned section 25 of each locking member may be deformed to prevent axial movement of the locking member.

Filed: 1927-07-14
Abstract: 274,481. Racheeff, B., and Gofmann, M. July 15, 1926, [Convention date]. Chemical-reaction processes.-In a process for uniting metal parts, a mixture of powdered metals containing the same metal as the parts to be united is raised to a temperature such that the combustion of one or more of the metals is initiated, and the heat of combustion causes the parts to be united to be brought into contact with the same metal included in the uniting mixture at a temperature near the melting point. In one example, a mixture of powdered calcium and powdered aluminium in the proportion of 2 : 3 is incorporated in the proportion of one or two parts to nine to eight parts of powdered metal corresponding to the metals to be united. Thus for uniting cast iron, 85 per cent of powdered iron may be mixed with 15 per cent of calcium-aluminium mixture. The powdered metals are mixed into a paste by the addition of water or grease and placed between the parts to be united. The whole is then raised to a temperature of about 700‹ C. in a furnace or forge. This causes the metal in the mixture to become softened and to unite with the softened edges of the parts to be joined to produce a homogeneous weld.
