Title: Improvements in or relating to sewing machines
IPC: D05B73/12
Filed: 1931-09-30
Abstract: 376,103. Sewing-machines. UNION SPECIAL MASCHINENFABRIK GES., 33, Schwabstrasse, Stuttgart, Germany. Sept. 30. 1931, No. 27194. Convention date, March 24. Addition to 366,433. [Class 112.] Chain-stitching.-The looper 28, as shown in the Figure, of the parent Specification is provided with needle guides 51 to ensure correct positioning of the needle 6 so that the looper will enter the needle thread loop. These guides 51 are secured to the looper below the blade so that when it moves forward the guides will place the needle, if deflected from its path, into position so that the looper will pass it on the right side and close to the needle. The mechanisms of the parent Specification for reciprocating the needle, for holding the work, and for oscillating and rotating the looper in the desired manner are also modified. The needle bar 5 is reciprocated once for each rotation of the main shaft 3 by a link 13 which is connected at one end to a collar clamped on the needle bar 5 and at the other end is secured to a crank pin 12 carried by a pinion 11 which is in gear with a pinion 8 on the main driving shaft 3 and which is mounted in a casing 10 secured to the shaft 3. The casing 10 carries a cam surface 23 which raises the presser-bar against a spring, which normally holds it to the work on a plate 14, when the needle is at the top of its stroke, to permit the work to be fed. When the needle moves down, an arm of a collar clamped to the needle bai compresses the spring to hold a presser foot, composed of inner and outer sections 15, 15a loosely connected together and provided with spherical seating surfaces, into contact with the work, and so as to permit the foot to adjust itself to irregularities in work thickness. The looper 28 is oscillated on its support into and out of the needle loop by a rod 34 having a ball connection 36 with the shank 29, which supports the looper. The rod 34 is actuated from a cam drum 40 by a pivoted lever 37. Rotary motion is imparted to the looper-carrier by a rack bar 45 having cylindrical portions at its ends which fit in an adjustable eccentric bore in a sleeve 46 so that it may be set relatively to a pinion 44 on the looper support. The bar 45 is reciprocated by a rod 48 through a pivoted lever 49 which is oscillated from the cam drum 40. The looper is thus rotated first in one direction and then in the other while the looper is at the forward end of its stroke so that on its reverse rotation the needle thread loop is placed about the needle.

Filed: 1928-09-22
Abstract: 321,767. Whitby, H. Sept. 22, 1928. Springs, arrangement of; equalizing load on wheels.-In a motor-vehicle having more than four wheels, particularly a six-wheeled rigid frame vehicle, of the kind in which certain of the wheels, e.g. the four rear wheels, are adapted automatically to position themselves in a coordinated manner when steering or turning movements are being effected, and in which a common spring suspension for the vehicle frame is associated with the axles of the wheels having such co-ordinated movements, the rear axle or axle casing is adapted, when the vehicle is being driven forwardly, to move parallel to itself, while the intermediate axle pivots about a fixed point on the frame. In the construction shown, the frame 4 is supported at either side of the vehicle on longitudinal springs 7, 8, Figs. 1 and 2, to the centres of which are pivoted girders 11, 12 of inverted channel section the' connection comprising a D-shaped bearing-member 13, Figs. 3 and 4, and a vertical pivot or bolt 14 having a certain amount of lateral play, so that the girders 11, 12 may have a horizontal swivelling and also a rocking movement in relation to the springs 7, 8. At their forward ends the connections between the girders 11, 12 and the casing 5 of the front axle 6 are such as to allow each girder to pivot about a vertical axis, to slide longitudinally and to rock about an horizontal axis relative to the axle 6, while at their rear ends the girders are connected to the rear axle 40 by ball-and-socket joints. The axle casing 5 is attached to a torque tube 1 which is ball-jointed at 2 to a cross-member 3 of the vehicle frame. In this manner, when a turning movement is being effected as shown in Fig. 2, the axles 6, 40 undergo lateral displacement and the axle 6 becomes inclined, while rocking movements of the frames due to unevenness of the ground are also permitted. If desired, the springs 7, 8 may be inserted, being pivoted at their centres to the frame 4 and connected at their ends to the girders 11, 12 or to the axle casings, and a fifth rear wheel may be centrally disposed between the axles 6, 40. In a modification, the axle 40, instead of being restrained always to move parallel to itself, may, through the medium of push-rods actuated by the front axle, be given an inclined position when the vehicle is being backed and turned simultaneously ;. while, in a further modification, the axle 40 is arranged to carry one central wheel only instead of two side wheels.
