Title: Thread tension devices for lock-stitch sewing machines
Inventor: GARBE RUDOLF
IPC: D05B47/00
Filed: 1951-06-20
Abstract: 701,229. Electric control systems. SINGER MANUFACTURING CO. Dec. 20, 1951 [June 20, 1951], No. 14601/51. Class 40 (1). [Also in Group VII] In a lock-stitch sewing-machine having a thread tension device comprising discs 48a, 50a urged together by a spring 67 the drag exerted by the device on the needle thread is controlled by electro-magnetic means to vary with the sewing speed of the machine. An armature is secured to the main shaft 24a of the machine and is disposed between pole pieces 61 the field windings 62 of which are connected to a coil 63 surrounding a soft iron core 64 carrying a pin 65 extending through the tension device. As shown the drag of the device increases as the sewing speed increases, but the invention includes machines in which the drag decreases as the sewing speed increases. In a modification, Fig. 6 (not shown), the coil is supplied from a D.C. generator associated with the main shaft.

Abstract: 354,767. Hypodermic needles. EVERETT, S. J., 939, London Road, Thornton Heath, Surrey. May 13, 1930, Nos. 14739 and 32908. [Class 81 (ii).] The attachment of a hypodermic needle to a mount is effected by resiliently supporting the needle d in the bore c of a perforated die a, and uniting therewith a perforated blank h, preferablv of soft metal such as pewter by the pressing operation of a plunger j, the blank being supported by the die and conforming to the shape of the cavity. The needle is held at its lower end by a blade spring e and descends to its correct position on engagement by the plunger, thus rendering initial positioning of the needle in the die unnecessary. The plunger is preferably of taper form, so that the interior of the mount may be readily fitted on to a syringe with a liquid-tight joint, and the conical centre of the mount facilitates the introduction of a wire into the needle for cleaning purposes, The top end of the needle is roughened or screw-threaded, and the interior wall of the cavity b may be grooved to produce a knurled surface on the moulded mount. In the modification shown in Fig. 4, the mount is formed to the desired cup-shape from sheet metal such as copper or brass before :it is united to the needle, and on depression of the plunger, the conical end m<2> of the mount enters the flared mouth n of the bore and a part is forced into the narrow bore c<1>.

Abstract: 259,638. Bell, M. r. June 12, 1925. Mechanical telegraphs; mine and colliery signals.-Relates to apparatus wherein a drum or plate is rotated to expose a direction or notice, the rotation being effected through two notched wheels one of which is rotated by the upward and downward movement of a bar having a rocking pawl attachment the pawl falling into engagement with the notches on the wheel at every upward movement of the bar and on every downward movement of the bar the pawl is disengaged by a fixture, the two wheels being retained by two pawl levers one of which is released by lever and roller trip gear and the other by a pin moved from the lifting bar or alternately from the lift cage or winding engine. A lifting bar B is actuated one or more times to ring a gong and carries a pivoted pawl N which advances step by step a ratchet wheel 2 loose on a shaft A and provided with a projection K1 adapted to engage a similar projection K2 on and rotate a ratchet wheel 1 fast on the shaft A which also carries an indicating drum P. The drum is rotated step-by-step to expose through a slot T1 a number and indication corresponding to the number of times the bar B has been moved upwards. The wheels 1, 2 are retained in position by pawls E, F of which the pawl F is released by a pin P1 on a pivoted dog Z which is moved by a lug Y on the bar B during the first part of the upward movement. The part E is released in the following manner. A roller C is adapted to roll on both an inclined plane D and a lever O. When the bar B is moved upward, the lover O is tilted by the arm R and the roller moves to the right the pawl E engaging the wheel 2 under the weight of the linkage. On downward movement of the lever, the roller moves back to the stop X and releases the pawl. A cautionary signal indicating " Men riding " is given thus. Un the third upward movement of the bar B a cam lever H with two lips moving with the shaft A contacts with a jointed arm K to rotate a disc D<1> and raise a plate M showing this signal. A fourth movement of the bar brings the second lip of the lever H into contact with a lever L and restores the disc and plate. The plate may be restored and the pawls F released by operation of a lever C1 by a cage or engine attachment; a slotted link U operating the plate M and loose link T with a roller at the lower end operat. ing the pawl. The dog Z is repositioned at the end of a signal by a projection on the wheel 2 engaging a guided link W which through a pivoted link J engaging the dog by means of a roller pushes the nose of the dog back over. the projection Y.

Title: Improvements relating to warp stop motions for looms for weaving
IPC: D03D51/20
Filed: 1921-06-02
Abstract: 185,228. Spence, R. L. June 2, 1921. Stop - motions, warp.-A device for stopping a loom on failure or breakage of a warp thread comprises detectors 9, Fig. 2, having open-ended lower slots to straddle the wa.rp threads and closed upper slots, through which pass a reciprocating serrated bar 6 and fixed serrated bars 1, 2. The bar 6 is positively moved in the direction of the arrow 10 by a cam 7, and the reverse movement is effected by gravity or other action. On a thread breaking, the corresponding detector 9 falls on to the bars and arrests the reverse movement of the bar 6, thereby placing a projection 15, Fig. 1, in the path of a plate 16 on the stay, which thus forces back the projection 15 and operates the starting-handle to stop the loom. The teeth of the fixed bars are made so that a fallen detector lies at an angle to the vertical plane and thereby opens the warp. A single fixed bar may be used and the reciprocating bar positioned in a channel therein.

Convention date, June 22, 1931. [Class 100 (i).] In a means for associating paper sheets travelling at different speeds in paper-folding apparatus having a transfer cylinder driven with varying speed which takes up the slowerrunning sheets at their own speed and transfers them with acceleration to the quicker-running receiving cylinder, the transfer cylinder is driven from a shaft 26 by gearing which is independent of the gear wheels of the folder, which is driven from a shaft 11. The quicker-running web 1 is led between a cutting cylinder 2 and the receiving cylinder 3, and the first cut sheet or set of sheets is passed on to a collecting cylinder 4 which carries it round to the point of contact to associate it with a second sheet or set of sheets on the cylinder 3. The slower-running web 5 enters between the cutting cylinders 6, 7, from which the cut sheet or set of sheets passes over the cylinders 8, 9 to the transfer cylinder 10 and thence to the receiving cylinder 3 to associate with the rest of the sheets. The combined sheets are folded by the cylinder 3a and delivered therefrom. All the cylinders, except the transfer cylinder 10, are driven through gears from the shaft 11, the drive being carried past the cylinder 10 by the provision of loosely mounted spur wheels on the shaft of the latter. On the opposite end of the shaft of the cylinder 10 is secured a non- circular spur-wheel 25 which meshes with a similar wheel 24 loosely mounted on the shaft of the cylinder 9 and driven by bevel wheels 27, 28 from the shaft 26. The non-circular spur-wheels 24, 25 may be replaced by other gear, such as a crank gear.
