Title: Zigzag-stitch sewing machines
IPC: D05B3/02
Filed: 1930-12-04
Abstract: 360,231. Sewing-machines. SINGER MANUFACTURING CO., Elizabeth, New Jersey, U.S.A. Dec. 4, 1930, No. 36564. Convention date, Sept. 23. [Class 112.] The means for automatically varying the amplitude of lateral vibration of a needle bar and the means for changing from one to the other of the stitch groups shown in Fig. 9 are so arranged that a zero setting of the amplitude adjusting device remains unaffected by a change of the vibration axis. The invention is illustrated as applied to a laterally vibrating lock-stitch rotary hook embroidering machine, described in Specification 324,613. The needle 23 is carried on a needle-bar 15 which reciprocates in bearings 16, 17 of a swing- ing frame 18 pivoted on a pin 19 with an eccentric reduced portion 20. The needle-bar is reciprocated by the main shaft 8 through the linkage 11 .. 14 in the usual way. The frame 18 is vibrated by the rock shaft 37, a cranked part 36 of which engages the frame at 35. The shaft 37 is rocked by a triangular cam 46 secured to the gear 47 through the linkage 44, 42, 41, 40. The pitman 44 has a bifurcated end 45 embracing the cam 46 and has a bifurcated link 52 secured to it by a pin 50. The link 52 is pivoted at 53 to a crank arm 54 of a crank shaft 55 journalled in an eccentric bushing 56. The amplitude of needle vibration is adjusted by an arm 77 fixed to the end of the shaft 55. The movement of the arm is limited by stops 81, 82 or intermediately by stops 73, 74 on a segmental plate 71. To give a stitch group symmetrically disposed about its axis as S<1>, Fig. 9, instead of one with one straight edge as S, an arm 62 attached. to the bushing 56 is swung from the position. shown in Figs. 1 and 4 to a position where a latch. pin 63 enters a socket 70. This bodily displaces the shaft 55 about the axis of the bushing 56 and the pivot 53 on the crank 54 moves normally to an imaginary line between the cam axis and the pivot of the pitman 44 on the link 42. While the pivot 53 lies on this line, the shaft 37 will not be rocked and the needle will reciprocate without vibrating. The pivot 53 is brought back to this line by a stop screw 84 on the arm 62 engaging the controlling arm 77. The shaft 55 is thereby rocked to bring back the pivot 53 into the imaginary line. This adjustment moves the mean position of the needle reciprocation axis out of the vertical and it is brought back to the vertical by turning the pivot 19 of the frame 18 about its eccentric extension 20. A scale is fitted to facilitate the setting. Specifications 8706/13 and 324,613, [both in Class 112, Sewing &c.], are referred to.

Abstract: 369,262. Colour photography ; optical systems. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Nov. 18, 1930, No. 34715. Convention date, Nov. 18, 1929. Addition to 356,701. [Classes 97 (i) and 98 (ii).] Relates to the reproduction by projectionprinting, according to the parent Specification, of a colour-record lenticular negative film on to a sensitive lenticular film without lateral inversion, and more particularly to the method wherein the negative film is illuminated from the lenticular side by an extended source of light, and a slit diaphragm inclined at an acute angle to the direction of the lenticular elements of the negative film is placed at the point of the optical axis of the system which corresponds to the position of the colour-band filter in the original exposure system in order to eliminate harmful interference effects. According to the invention, the extended light-source and the slot are replaced by a thin incandescent filament inclined at an acute angle to the lenticular elements of the negative film and of such a breadth that the interference images projected by the lenticular elements of the negative film do not cover one another. As in the parent invention, a second diaphragm may be used, situated at the position of the real image of the filament, and having a slot parallel with the filaments.

Abstract: 786,931. Hypodermic syringes. YOCHEM, D. E. Dec. 28, 1955 [Jan. 10, 1955], No. 37092/55. Class 81 (2). A hypodermic syringe has a gauge including an apertured guide 33 mounted on the barrel, a gauge member 31 mounted on the plunger 21 and passing through the guide opening 34 and a stop member 44 which is adjustable along the gauge member 31 to predetermine the amount of liquid drawn into the syringe on withdrawal of the plunger 21. The guide arm 33 is carried by a clasp 30 mounted on the syringe barrel 20 so that it abuts a flange 25 at the rear end of the barrel 20. The gauge bar 31 is secured to the head of the plunger 21 by a clasp 41 and passes through the opening 34 in the arm 33. A slot 35 in the arm 33 enables the bar 31 to be removed from or inserted into the opening 34 by rotating the plunger 21. The stop member 44 is slidable on the bar 31 and is secured in any desired position by a screw 46. Retraction of the plunger 21 is limited by the engagement of the stop member 44 with the arm 33. A compression spring (not shown) may be provided on the bar 31 between the stop member 44 and the arm 33. During an injection, the plunger is retracted against the spring to indicate whether the syringe needle has penetrated a blood vessel.

Abstract: 1318285 Sampling liquids GILFORD INSTRUMENT LABORATORIES Inc 5 Aug 1970 [12 Aug 1969] 37739/70 Heading B8N In a method of sampling liquid using a frangible sealed-end evacuated capillary tube having a fracture-promoting mark or score thereon, the tube is lowered into a liquid so that the mark is below the liquid level and the tube is then fractured at the mark. In the embodiment of Fig. 5 the tube 10 is inserted into a container 50 via a passageway 56 in a cover member 52, e.g. of a synthetic resin of a polymerized type. The passageway may have at its bottom end a flapper valve and/  or a pair of abutting lips or flaps at its upper end which are opened by the tube. The container wall is preferably transparent, is flexible and is sealed or thermally welded to the cover member 52. In use with score 22 below the liquid level the tube is manually grasped on either side of the mark and a bending force is applied thereto to facture the tube. The upper portion of the tube is then withdrawn and may be broken into predetermined shorter lengths so that the liquid therein may be used in micro-sample testing. When using the apparatus of Fig. 1, movement of the capillary tube 10 downwardly relative to a support 26 effects fracture at the score 22. The support may be made of nylon polyethylene, or tetrafluorethylene. The capillary tube, preferably has an external diameter of 0À040 inch, and is made of glass. In the arrangement of Fig. 4, the lower end of the tube 10 abuts a slant surface 29 provided on member 28<SP>1</SP> which is movable relative to support member 32<SP>1</SP>. When the member 311 is pushed towards the bottom of vessel 14<SP>1</SP>, the member 28<SP>1</SP> moves to apply a bending moment to the lower end of the tube, and the tube is then fractured at the score 22.
