Title: Improvements in cages for roller bearings
IPC: F16C33/46
Filed: 1945-09-12
Abstract: 584,120. Roller cages. TIMKEN ROLLER BEARING CO. Sept. 12, 1945, No. 23465. Convention date, Oct. 11, 1944. [Class 12 (i)] A resilient rollerbearing cage has interconnected pockets which are spaced apart so that a portion of the cage itself accommodates angular movement of the rollers 6. The resilience of the cage restores both cage and rollers to their normal positions. The cage is formed from a resilient strip shaped to form pockets and comprises two end members 10, 11, side or bridge members 12 each of which has a portion extruding along part of a side of one pocket, a cross-over portion 13, and a portion along part of a side of an adjacent roller. The cross-over portions 13 are crimped to intercept with each other and are preferably welded together. The cage is sufficiently resilient and expansible to permit it and the rollers &c. to be snapped over the retaining rib 3 on a bearing member 1. The close-fitting of the rollers in the pockets assists the guiding action of the thrust rib 2, and minimises the tendency of the rollers to move angularly out of position. If the bearing has an odd number of rollers, the cage is made of a single piece of wire which begins and ends at the same cross-over, the two free ends of the wire being welded to the cross-over. For an even number of rollers, two strips are necessary. The distance of the cage from the centre line of the rollers determines whether the rollers are in contact along their side edges, or are spaced apart. The cage may consist of wire of circular, oval, square, or oblong cross-section, and is shown applied to taper and cylindrical rollers.

Title: Tracer arrangement for copy tool machines, particularly copy milling machines
IPC: B23Q35/122
Filed: 1966-05-27
Abstract: 1,126,959. Template followers. NASSOVIA WERKZEUGMASCHINENFABRIK G. m. b. H. May 27, 1966 [May 28, 19651, No.23951/66. Heading G3N. [Also in Division B3] A tracer assembly for a copying machine tool comprises a tracer, a control head having a rotary member and a stationary member rigidly mounted on the tracer, the rotary member being rotatable within or around the stationary member about an axis perpendicular to the selected plane in which the tracer is intended to follow a pattern, biassing means urging the stationary member off centre relative to the rotatable member, drive means connected to the rotatable member, and switch means having three positions controlling the drive means for left hand and right hand and null rotation, the switch means taking up one or other of these positions in dependence upon the direction of off centredness of the stationary member relative to the instantaneous direction of feed movement of the tracer. A tracer 3, 4 in a copy milling machine is mounted by forked levers 2, 2' so as to be displaceable bodily i.e. parallel to its own axis in three co-ordinate directions such displacement being sensed by hydraulic valves 5, 6, 7 and used to effect corresponding feed movements of the tool and tracer. A ball 13 supported from the upper end of the tracer is surrounded by a rotatable control head 14 which has three electrical contact rollers 17,18,19 and a pressure member 23, 24, 25 adapted to press the ball 13 into an eccentric position relative to the head against one or more of the contact rollers 17, 18, 19. The electrical connections to the rollers 17,18,19 are such that the control head, which may be driven clockwise or anticlockwise by a motor 16, remains stationary when the ball 13 is in contact with rollers 18,17 or 18,19, this condition is reached when the control head is in a position such that the pressure member 23, 24, 25 exerts a control force on the ball 13 and thereby on the tracer directed at some desired angle e.g. 30 degrees, to the tangent to the tracer at the point of contact with the pattern. The control head 14 is supported in a housing 9, 10 which may be adjusted angularly about the tracer axis and about an axis perpendicular thereto, the particular setting of the housing determining the scanning plane for the tracer. When a change in direction of the pattern contour is reached the tracer is deflected so that the ball 13 moves to lose contact with one or more of the contact rollers 17, 18, 19 which results in rotation of the head 14 in an appropriate direction to restore contact and to restore the angle between the line of force under which the tracer is urged into contact with the pattern and the tangent at the point of contact to the desired value. In modifications Fig, 3, 4, 7, 8, (not shown) the rollers are replaced by arcuate contact segments while the measuring ball and head may be replaced by a ring member with a measuring disc member located within it and carrying the contact rollers or segments, Figs. 5, 6, 7, 8, (not shown).

Abstract: 909,537. Forced-flow steam boilers. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. July 13, 1959 [July 11, 1958], No. 23982/59. Class 123 (2). In a forced-flow, once-through steam boiler comprising a preheating section 1, an evaporating section 2, a transition zone 3 and superheater 4, the tubes of the sections 2, 3 are made of larger diameter and greater wall thickness than the tubes of the superheater so that on a sudden fluctuation of steam demand the steam temperature at the outlet of the superheater will be maintained substantially constant as the increased volume of steel in the thickened tubes takes up or delivers heat to the working medium while the normal boiler controls adjust the firing rate &c., to the new load. In the lower half of the Figure the upper curve represents the working medium temperature through the boiler under steady conditions when, for example, steam is being delivered at 150 atmospheres pressure. The lower curve shows the temperature conditions on a sudden increase in load. The increase temporarily lowers the boiler pressure to, say, 120 atmospheres, causing a fall in the evaporator outlet temperature. Heat is transferred from the thick walls of the sections 2, 3 to the working medium so that its temperature at the outlet from the transition zone is almost that obtaining at the higher pressure. A smaller amount of heat transferred from the walls of the superheater tubing restores the outlet temperature to its previous level, thus bridging the delay in the operation of the firing &c. controls.

Abstract: 1,181,606. Sewing-machines. SINGER CO. 21 May, 1968, No. 24047/68. Heading D1G. A sewing machine needle bar is oscillated by a stack of edge cams 41, 42, 43 which are all read by a single follower 56 and the phase angle of the cams can be altered to vary the switch formation. The variation is produced by rotation of the thumbwheel 80 fixed to the top cam 43 which rotates the cam 43 through a green angle and, through an intermediate member 64 (not shown), rotates the cam 42 through half that angle, both relative to the cam 41- thus changing from the arrangement shown in Fig. 1 to that in Fig. 3(c) and varying from simple zig-zag to the stitch shown in Fig. 9. Either stitch can be selectively held by a spring catch 82 which engages slots in the top of the thumbwheel. Field and amplitude control: The needle-bar moving pitman 24 is moved by a frame 29 pivoted at 30 and the amplitude control is provided by an angled slot 36 in a plate 37 fixed to the pitman 20 that on movement of the lever 38 the pitman is moved relative to the pivot 30 along the frame 29. To vary the field the pivot 30 is rotated about the pivot 32 by the lever 39. Seams: As shown in Fig. 9 a zig-zag stitch is formed after every three straight stitches.
