Title: Record changing device for gramophones and the like apparatus
IPC: G11B17/16
Filed: 1948-02-23
Abstract: 646,513. Automatic gramophones. STEURS, A. D. Feb. 23, 1948, No. 5363. Convention date, March 7, 1947. [Class 40 (ii)] In an automatic gramophone of the kind in which records are supported on a stepped centre-post and are pushed one by one therefrom to slip down on to the turntable, the pick-up arm and the record-feeding device are coupled together by a chain or similar member which is engaged during an automatic cycle by an eccentrically placed member on a cycling disc set in motion at the end of the playing of a record, so that the pick-up arm is pulled upwardly and outwardly, the record feeding device operated, and the pick-up arm lowered again on to the record. Motion of the cycling disc 14 is initiated when the pick-up arm 12 reaches a certain position in its traverse, by means of an arm 45, Fig. 2 (underneath view), which moves a forked lever 47 pivoted at 48 so that the pointed end 53 of a lever 51 pivoted at 52 moves out of the path of a boss 26 on the cycling disc 14, which is. then set in motion by the limb 54 of a spring 55. The motion of the cycling disc 14 is maintained by means of a jockey wheel 17, Fig. 7, which is'forced out of a notch 18 in the cycling disc 14 and comes into contact with a wheel 16 on the continuously rotating turntable shaft 5. During the firstquarter revolution of the cycling disc 14, the eccentrically placed member 25 acting on the chain 28, causes the pick-up arm 12 to be lifted and swung outwardly, Fig. 5. During the next quarter revolution of the cycling disc, the chain 28 tightens sufficiently, in opposition to a coiled spring 31, Fig. 11, to rotate the disc 32 of the record feeding device 13, so that pin 33 moves the slide 35 inwardly to unseat the lowermost record from the step on the centre - post 8, by means of a pin 37 if the lowermost record is a 12 inch record and by the tooth 40 if the lowermost record is a 10 inch record. During the remaining half revolution of the cycling disc 14, the slide 35 of the record feeding device 13 is returned and the pick-up arm 12 then lowered on to the start of a record. The starting position of the pick-up arm is set manually by means of a knob 61, Fig. 1, controlling a cam 62, Fig. 2, beneath the baseplate, and an arm 44 rigid with the pick-up arm shaft 43. Records may be rejected during playing by the operation of a knob 63 which trips the lever 47 by means of a rod 64, Fig. 2, and initiates a new cycle of the disc 14. The playing of any record may be repeated indefinitely by operating a knob 65, Figs. 1 and 11, which controls lever 66, rod 67, and cam surface on a rod 72, Figs. 11 and 14, whereby the tooth 40 and pin 37 is rendered ineffective in unseating further records from the centrepost 8.
Patent GB-660261-A (GB)
Title: Improvements in or relating to the screen printing of fabrics
IPC: B41F15/08
Filed: 1948-02-24
Abstract: 660,261. Stencilling-apparatus. STRIKER, M. S. Feb. 24, 1948 [March 13, 1944], No. 5414/48. Class 100 (ii). [Also in Group XV] A method of screen-printing fabric includes the step of securing the fabric to a printing table by means of a slightly sticky adhesive coating applied to the table and which remains thereon in a permanently slightly sticky condition after the fabric has been printed and removed. An adhesive-applying apparatus comprises rollers 14, 15 resting on a long printing table, a roll 20 of fabric to be printed, a container 21 for adhesive, and an electric motor 27 to drive the roller 14. The container 21 has an outlet 23 for the adhesive, extending the width of the Lable, and a distributing blade 25. The motor is connected to electric supply sails 34 alongside the table by contacts 33. Rollers 36, 37 engage a rail 40 secured to the table, to guide the apparatus laterally as it moves over the table. The roll 20 is also laterally slidable, within limits. In operation, the apparatus starts at the left hand end of the table, which is 60-90 feet long. Fabric is unwound from the roll and the end introduced between the roller 15 and the table. The motor circuit is established, the outlet 23 opened, and the apparatus moves along the table, applying a layer of adhesive and thereon a layer of fabric. At the end of the run, the circuit is broken, the outlet 23 closed, manually or automatically, and the apparatus stopped. Unless the whole length of the fabric on the roll 20 has been used, the length on the table is then severed, and printing takes place before or after the apparatus is returned manually or by the motor to the left end of the table. On subsequent runs, the outlet 23 is closed, since no further adhesive is required. To ensure that the apparatus remains in contact with the rail 40, the roller 37 may be located nearer the longitudinal centre of the apparatus than the roller 36, or the axes of the rollers 14, 15 may be slightly out of parallel. The adhesive is non-aqueous and may be wax or waxlike, in which case heating means are combined with the container 21.

Abstract: 514,988. Sewing-machines; seams. UNITED STATES BLIND STITCH MACHINE CORPORATION. Feb. 21, 1938. No. 5426. Convention date, April 2, 1937. [Class 112] A facing strip 27, Fig. 9, is attached to a garment W by securing the edges of the parts together at S, turning the facing over and folding its edge at 43 as shown, and then connecting the parts by blind stitches through a bight 42 formed in the part W at a distance from the fold 43 and through the fold; the fold is preferably raised during the sewing by forming a second bight in the part W beneath it. A chainstitch seam is preferably used, to provide an elastic connection. A curved-needle machine for producing the blind-stitch seam referred to has an oscillating work-bender R with two ribs 24, 25 separated by a concave part 26. The work is supported before stitching on a table 50, Fig. 4, carrying an adjustable plate 51 by which the fold in the facing 27 is guided, and is held against the needle-plate 10 and the feeddog by fingers 14, Fig. 5, hinged to spring- biassed members 22 pivoted to the worksupporting frame 16. The work is also engaged by spring hinged fingers 60 placed above the ribs 24, 25 and by a finger 30 which is placed between and below the fingers 60; the finger 30 guides the fold 43 of the facing in relation to the ribs of the work-bender, and is carried on a laterally adjustable mount 32, Fig. 4, so that the fold 43 may be kept low and at a distance from the bight 42 for thin work, as in Fig. 9, or may be allowed to extend further, as in Fig. 16, in the case of thick work. The workbender R is retracted during feed of the work, and is so shaped that contact with the work is then minimised; the finger 30 is formed with a sharp lower edge, bevelled on the side facing the high rib 24, also in order to reduce the resistance to feeding. The ribs 24, 25 may be formed on independent members.

Abstract: 740,913. Liquid-flow indicators. HIPWELL, P. March 24, 1954 [March 4, 1953], No. 6071/53. Class 69 (1). A liquid-flow indicator comprises (as shown in the schematic Fig. 4) an inlet passage 15, an outlet passage 28 and a sight passage 18 all extending parallel to each other, a metering connection 22 between the inlet and outlet passages, an overflow connection 23 of larger cross-section than the metering connection and which is also between the inlet and outlet passages, a tapping 25 from the inlet connection adjacent the metering connection to the sight passage and a second tapping 26, 19, 27 from the other end of the sight passage to the outlet passage, the second tapping being so arranged that the sight passage does not receive any liquid through it when no liquid is flowing through the overflow connection. In the form described (Figs. 1-3) for use with a milking- machine, the passages 15, 28, 18 and passage 19 forming part of the second tapping are bored in a laminated block of " Perspex " (Registered Trade Mark), the passages 15, 19, 28 being in an opaque lamination 21 and the passage 18 being in a transparent lamination 20. A metal cup 10, having an inlet nipple 11 and a filter 13, is attached to the top of the block by a rubber sleeve 12 having a partition 14 with a bore (not shown) which aligns with the inlet passage 15 and a rubber sleeve 17 having an outlet nipple 24 is fitted to the bottom of the block. The metering connection 22, the tapping 25 and the duct 27 (forming part of the second tapping) are all formed by grooves in the lower end of the block, the duct 26 (also forming part of the second tapping) is formed by a groove in the upper end of the block, and the overflow  c onnection 23 is formed by a groove in the partition 14 of the rubber sleeve. The duct 27 is of greater cross-section than the duct 26, thus preventing liquid from entering the sight passage from the outlet passage when no liquid is flowing through the overflow connection. In a modification, a hard rubber block is used instead of a laminated one and a transparent insert, e.g. of glass, is fitted so that the sight passage can be observed.
