Abstract: 980,319. Machine frames and sliding carriages. DEREFA ETABLISSEMENT POUR LE DEVELOPPEMENT RECHERCHES ET FABRICATIONS INDUSTRIELLES. May 23, 1961 [May 23, 1960 No. 18572/61. Heading B3B. A mechanical control device for adjusting the lubricant pressure at given points on the slideways of machine tools in relation to the loads at these points comprises a regulator unit 62 with cam rails 102 each supported adjacent its ends by cams 121 and 122. The cams are specifically positioned in relation to each other and are stacked on splined shafts 123 and 124. Pressure contact between the cams and rails is maintained by spring-loaded plungers in units 108 and 141. A two-part valve housing 105-108 supported from the machine slide 47 contains pressure control valves whose operations are determined by presetting the level and inclination of the cam rails 102 by rotation of the cam-shafts 123 and 124, in conjunction with indicia 146 and 146a on dials 125 and 125a. Lubricant supplied from a pressure source is fed to the regulator 62 via the valve housings 105-108 wherein the pressure control valves, having valve adjusting elements operatively connected to a movable machine part, vary the oil flow to respective points on the slideway to offset variations in the load distribution and maintain the oil film substantially constant.

IPC: A41H1/02
Filed: 1926-07-26
Abstract: 278,824. Maia, G. July 26, 1926. Drafting and cutting-out; measuring. - An extensible pattern for use in cutting out upper garments comprises a body portion having the smallest size and out-line of the class of pattern to be cut, slides on the upper part of the body movable substantially lengthwise of the body, other slides movable transversely of the longitudinally moving slides, scales on all the slides, and a scale combined with a button acting as a centre of rotation on which the whole is rotated to compensate for abnormalities such as roundness of the back. Fig. 2 shows the pattern for the front of a coat, the body portion 6 carrying a slide A' movable lengthwise in accordance with measurements taken heightwise on the body, this slide carrying a slide B<1> movable transversely in accordance with the lateral movements. To compensate for abnormal roundness of the back, the pattern is provided with a button K<1>. After adjustment of the slides in accordance with the body measurements, the outline of the adjusted pattern is traced on the material below the button only. The pattern is then rotated about this button an angle determined by graduations on a scale C<1>, the remainder of the outline being traced in accordance with the new position of the pattern. A similar pattern with two lengthwise moving slides, and a pair of transverse slides of which one moves on the other, is described for the corresponding back half garment. The similar pattern for the sleeve comprises a slide moving at a slight angle to the length of the pattern, and a slide moving obliquely across this slide and carrying a radius member for describing part of the arm hole. Some of the body measurements are taken with a tape measure, and others with a known apparatus shown in Fig. 6. This apparatus comprises an upright rod 101, a transverse rod 102 fixed thereto, upright rods 115 slidable vertically and transversely with relation to the rod 102, rods 124 intended to extend over the shoulders, secured at right angles to the rods 115, and rods 127 depending from and slidable along the rods 124. All these rods are graduated. The upper end of the rod is slotted and provided with a slide through an aperture of which is passed a graduated rod 120. The rod 101 is set vertical by a slide 123, parallel to the rod 120. The rod 120 is also used to determine the position of the lower part of the armpit and the depth of the hollow of the back. A rule is provided for use with the patterns, so that the outline drawn from the patterns may be varied for the hollows of the back and hips and allowance made for crossing at button-holes. The Specification describes in detail the method of using the apparatus and of graduating the scales.

[Class 123 (ii)] The heat carrier of an indirectly-heated boiler moves in a closed circuit and is itself heated from an outside source while imparting heat to the boiler evaporating tubes, &c., which deliver into a steam-and-water drum ; the tube system of the heat carrier circuit lies wholly outside the drum. In a boiler suitable for vehicles the generating tubes comprising the main heat absorbing part of the closed circuit of the heating medium form the furnace walls and discharge into a collector 3 or a drum 4, whence steam passes through jacket or heat-emitting tubes 8 and is returned by tubes 27 to a base ring 1. Combustion gases flow in a zig-zag path determined by baffles 10, 12, to the chimney so as to transfer heat to tubes 8. The indirectly heated boiler comprises tubes 16 connecting a steam and water drum 18 and vertical chambers 20 and passing through the tubes 8, with a return circulation through tubes 22 and a water drum 21. Steam generated passes from a superheater 7 to the place of use.

Spring power-storing mechanism. -In spring motors having two driving springs in series, particularly motors for phonographs, means are provided whereby on the rupture of one of the springs the unbroken spring may be put into operation. Fig. 1 shows a motor having two springs housed in barrels 13, 11 connected so as to rotate together by being bolted &c. to a partition 17, the inner ends of the springs being fastened to bushings 5, 7. These bushings are rotatably mounted on sleeves 25, 27 fixed to the non-rotatable supporting rod 4.

The rod 4, together with the clutch member 23, is movable endwise by means of an eccentric plate 41, rod 39, and button 38 mounted outside the motor board. The winding is accomplished by means of the ratchet-wheel 8, and the drive is transmitted by the gear 6 mounted on the bushing 5. Should the spring in barrel 11 break, the clutch is engaged with the bushing 7, and winding of the unbroken spring is then transmitted through bushing 7 and barrels 11, 13; in the event of the spring in barrel 13 breaking, the clutch is engaged with the bushing 5. The invention is applicable to spring motors generally, such as motors operating signal apparatus.
