Title: Improvements in web-manifolding arrangements for typewriting machines
IPC: B41J17/00
Filed: 1925-12-02
Abstract: 256,452. Fairweather, W. C., (Underwood Typewriter Co.). Dec. 2, 1925, Web feeding and guiding arrangements; inkribbon mechanism.-In web-manifolding arrangements comprising means for periodically retracting carbon sheets interleaved with the webs, the carbon sheets are attached to a normally stationary carrier, free movement of the platen carriage being permitted by arranging the webs in a long loop, and means are provided for straightening the webs to permit retraction of the carbon sheets without raising the platen. The typewriter 10 is equipped at the rear with a revoluble counterweighted frame 42 supporting a carbon-sheet carrier 23 and a cylindrical member 41. The frame 42 is pivoted to standards 26 on a base 26<b> and is revoluble by means of a fingerpiece 33 on a slide 34 connected to a sector 39 gearing with a pinion 40 on the frame. The carbon sheets are provided at the top with clips consisting of folded strips which are hooked on to strips secured to tabs or sheets 29a of paper, cloth, celluloid, &c. attached to blades 27 on the carrier 23. When the frame 42 is in the position shown in Fig. 4, webs 21 or a longitudinally folded web consisting of a series of forms are interleaved with the carbon sheets, passed round the platen 12, and pulled over a shelf 30 until the third form is in position for typing; the carbon sheets extend initially over the third form, the first two forms being used merely for manipulating the webs. The frame 42 is then turned to the position shown in Fig. 1 to form a long loop 28<b> Fig. 4, the frame remaining in the position shown in Fig. 4 during typing. On completion of the third form, the carriage is returned to mid position and the frame 42 is turned 'back towards the position shown in Fig. 4, the member 41 straightening the remainder 28 of the loop, and the webs and carbon sheets being retracted until the carbon sheets are clear of the platen. The feed-rollers 16 are then released, the webs are secured by applying a clamp 43 to the second form, and the return movement of the frame 42 is completed, the carbon sheets being thereby retracted into register with the fourth form. The above-described operations are repeated in typing the fourth and subsequent forms. The movements of the frame 41 are limited by contact of stops 55, 55a with one of the standards 26 and an adjustable stepped stop 57 respectively. The webs pass over a guide 22 on the member 41, and between adjustable side guides 42<a>, 15a mounted on a rod 42b on the frame 42 and on the paper-apron 15 respectively. The clamp 43 is secured to arms 48 pivoted to brackets 49 which can slide in graduated slots 59 in the shelf supports 31 and are secured by screws 62. Web-Cuttting arrangements.-The leading forms on the webs are torn off by means of a knife 47, Fig. 1, secured to the above-described clamp 43. The blades 27 on the carbon-sheet carrier 23 may be formed at the ends with knives for cutting a longitudinally folded web along the folds.

Filed: 1935-11-08
Abstract: 465,782. Compound sheet materials. BRITISH CELANESE, Ltd., and WALKER, W. Nov. 8, 1935, No. 30923. [Class 140] [Also in Groups XVI and XXII] Heat-insulating sheet material consists of a pleated or corrugated composite sheet comprising at least one layer each of a metal and of a synthetic, heat-insulating, thermoplastic composition, the thickness of the several layers being between 0À0002 and 0À015 inch. Aluminium, copper, or tin foil may be covered on one or both sides with cellulose acetate foil, a cellulose derivative adhesive being used, or the cellulose acetate foil being moistened with a solvent. Alternatively the thermoplastic composition may be flowed or cast directly on to the metal foil, e.g. an acetone solution of cellulose acetate may be applied to a travelling sheet of foil and allowed to dry. The material may be pleated in a paper or fabric pleating machine. The material may be softened by means of steam before pleating, and the pleating rollers may be heated. A number of pleated sheets may be superimposed to form a heat-insulating structure. The pleats in alternate layers may cross one another, and the layers may be united by an adhesive or by softening the cellulose derivative with a solvent. For example a number of composite pleated sheets each comprising one layer each of metal foil and of cellulose acetate, and one sheet comprising one layer of metal foil between two cellulose acetate layers, may be superimposed to form a structure in which cellulose acetate and metal alternate. Other organic cellulose derivatives may be used in the heat-insulating layer, and this layer may contain plasticizers, pigments, fillers, dyes, fire-retardants, waterproofing agents, and aluminium or bronze powder.

Title: Improved method of and means for crimping sheet material
IPC: B31F1/18
Filed: 1935-11-08
Abstract: 459,966. Pleating paper &c. ZELLSTOFFFABRIK WALDHOF, 156, Sandhoferstrasse, Waldhof, Mannheim, and HAAS, R., 2, Auf dem Grat, Dahlem, Berlin, both in Germany. Nov. 8, 1935, No. 30955. Convention date, Nov. 12, 1934. [Class 141] [See also Group XVI] A method for crimping sheet material, for example paper, comprises the successive steps of pressing uniformly a substantial area of the material against the surface of a deformable body, or between the surfaces of deformable bodies, and while maintaining a uniform pressure, causing or allowing the body or bodies to alter in shape or size so as to produce a contraction of the said surface or surfaces. As shown in Fig. 1, one or more sheets of material 1 are placed between deformable bodies 2, 3, which are pressed towards each other by suitable means, and the bodies 2, 3, are then compressed laterally by means of pressure blocks 5. The deformable bodies may be composed of rubber, or of a number of strips of metal, leather, or artificial material, movable with respect to each other. The deformable bodies may be provided with heating means. In a modification, the crimping is effected between cylindrical surfaces. In a further modification, Fig. 6, a continuous strip 14 is crimped intermittently by being passed between bodies 16 which are deformed by means of two lateral curved cam tracks 17. The latter may be fixed, in which case the intermittent feeding of the strip 14 occurs simultaneously with the crimping, or the bodies 16 may be fixed in which case, the feeding of the strip takes place alternately with the crimping. In a still further modification, a strip is crimped intermittently by being passed between a body having an arched surface, and movable to-and-fro with respect to a deformable hollow counter body to which pressure liquid is supplied. Specification 376,040, [Group XXII], is referred to. The Specification as open to inspection under Sect. 91 comprises also means for crimping the sheet material simultaneously in two or more directions, e.g. transversely and longitudinally or radially. This subject-matter does not appear in the Specification as accepted.
