Title: Improvements in and relating to laundry folding machinery
Inventor: HASTIE WILFRED ARNOLD
IPC: B65H29/34
Filed: 1952-05-13
Abstract: 715,548. Endless conveyers. MANLOVE, ALLIOTT & CO., Ltd. March 25, 1953 [May 13, 1952], No. 12108/52. Class 78 (1) [Also in Group VIII] In a machine for folding laundered articles, the articles are transferred from a first conveyer 10 to a second conveyer 12 arranged at a lower level than conveyer 10 and running transversely to it; articles are received from conveyer 10 'by a platform lying substantially in the plane of the upper run of conveyer 10 and above conveyer 12, and the platform is formed of two plates 14 which can move away from each other to provide a gap through which the article will fall on to conveyer 12. When the leading edge of an article 16 on conveyer 10 raises an arm 26, a solenoid 24 is energized to swing plates 14 up about pivots 18 to the article-supporting position. When the passing of the trailing edge of the article allows arm 26 to fall, the solenoid is de-energized after a suitable delay, and plates 14 swing down to let the article fall on to conveyer 12. Fingers 36 between the tapes of conveyer 10 bridge the gap between the conveyer and the platform. The platform may be horizontal or may slope slightly upwardly or downwardly from conveyer 10. Plates 14, instead of swinging, may move towards and away from each other in a horizontal plane. As shown, conveyer 12 lies at right angles to conveyer 10; according to the Provisional Specification, the two conveyers may be arranged at some other angle, e.g. 45 degrees.

Title: Improvements in the manufacture of fibrous mats, particularly of glass fibres
IPC: D04H1/72
Filed: 1961-04-05
Abstract: 907,443. Making fibrous mats. COMPAGNIE DE SAINT-GOBAIN. April 5, 1961 [May 5, 1960], No. 12123/61. Classes 120 (1) and 120 (3). Fibrous mats, particularly of glass fibres, are formed by passing fibres that are to be deposited on a perforated suction conveyer through guides having a frequency of oscillation exceeding 250 oscillations per minute. It is stated that oscillation frequencies of this order result in fibres being laid across the width of conveyers very uniformly. In an example, guide members 11 formed from two aprons 6 to 7 cms. in height and located 150 cms. above a conveyer were actuated at 400 strokes per minute. The fibre producing unit A may be located above the longitudinal axis of the conveyer or may be offset. Two or more units A may deposit fibres on a single conveyer.

Abstract: 162,620. Hanseatische Triumphwerke Ges., (Assignees of Heydenbluth, E., and Evard, R.). April 29, 1920, [Convention date]. Cutting-edges, shaping and treating. - A machine for grinding double-edged safety-razor blades comprises an endless steel conveyer-bandg, Fig. 1, which carries the blades past three sets of grinding-discs b, each set comprising four discs, one for each cutting-face of the blades. The three sets serve successively for coarse grinding, fine grinding, and polishing. The conveyer-band g lies in a channel k, Fig. 3, in a guide-rail ! i and stop-pins o, Fig. 5, having heads with parallel sides, pass through holes in the conveyer-band g and also holes in a blade p. The heads of the pins slide in a. channel m in the rail i and the shanks of the pins project into a channel l in an upper guide-rail h. The blade is thus kept from wobbling during its passage through the machine. The rails h, i are out away, as shown at n, to allow the grinders to contact with the edges of the blades.

Abstract: 542,938. Ink-ribbon mechanism. BRUMHILL, C. W. July 31, 1940, No. 12410. [Class 100 (iv)] A device for feeding a ribbon, particularly a carbon ribbon which is used once only, can be readily substituted for one of the usual ribbon-spools of a typewriter, and is driven by the existing spooldrive at such a rate that successive type-impressions do not overlap. The device shown in Figs. 1 and 3 is mounted as a unit on a base 11 which, after removal of the spool, is placed in the spool-cup. A rotatable sleeve 13, adapted to be slipped on to the spoolshaft, supports a rubber-faced roller 16a which is coupled to the sleeve by a feather 17 and is retained by a washer 18. The roller 16a co-operates with a pressure-roller 20 carried by a spring-urged lever 21. A plate 26 supports guides 24, 25 for guiding the ribbon R to and from the nip of the rollers. The sleeve 13 is geared to the roller 16a by pinions 28, 29, 31, 32 having a gear-ratio of, for instance, 1 to 3.25. The base is secured by co-operation of a lug 34, Fig. 2 (not shown) on the base, and a spring- urged lever 35 with opposite edges of a slot in the spool-housing.

[Also in Division G2] An apparatus for examining or reproducing a preselected frame of recorded material on a web (4) (e.g. a microfilm viewer) comprises (Fig. 1, not shown), two storage rollers (2) and (3) for the web 4 which may be passed from one storage roller to the other via rollers (6), 7 and (9) and a film platform (5) at which the web is examined or reproduced. As shown in Fig. 2, a cam 12 on a disc 11 on the spindle 8 of roller 7 co-operates once per revolution with a spring biased lever 13 to complete the electric circuit of an impulse acutated addition-subtraction counter which thus records the length of film passing the roller 7 by the number of revolutions of said roller. The film may be moved either backwards or forwards, the counter being operated accordingly by means of a switch 17 which is connected with a master switch for forward and reverse running or with a friction bearing. The web may be programmed by forming a signal notch in its lead portion which automatically zeros the counter. A particular frame or series of frames may be selected for viewing by observing the counter or by using a preselector coupled to the counter. In other embodiments the lever arrangement of Fig. 2 may be replaced by a micro-switch or a photosensitive device, and/or the disc 11 may have a plurality of cams 12.

Each landing in a mine shaft is provided with a bridge comprising a bottom plate and two side walls formed separately therefrom, the side walls being operated simultaneously with the bottom plate to bridge the gap between the cage and the side of the shaft when the cage is at the landing. The bottom plate 9 is hinged to the base of a structure 8 erected at a landing and carries a roller 11 which engages a channel member on the cage when the plate is horizontal. The side plates 2 of the structure carry rollers 3 which support the side walls 4 by engaging inclined slots formed in them. An actuating lever 14 pivoted to the structure is connected by a link 17 to a pivoted arm 15 and link 16. The latter link is connected to the plate 9, pins 12 on which engage stops 13 on the walls, so that when the lever is actuated the plate 9 and side walls move together. A catch 18 retains the bridge in position within the structure and a plate 5 on a side wall obscures the operator's signal 6 when the bridge is in operation.
