Abstract: 389,538. Fuel injectors; pumps. OLSEN, S. D., 99, Brookscroft Road, and OLSEN ENGINE SYNDICATE, Ltd., Salisbury House, both in London. July 31, 1931. No. 21935. [Class 7 (iii).] In a combined fuel pump and injection device the pressure in the engine combustion space is used to impart a rotary movement to the injection nozzle during the spraying period. Fuel is admitted to a pump 2 through terminal ports and is discharged into a passage 9 through a cam-actuated valve 10. From the passage 9 the fuel is conveyed to a central duct 5 in the pump plunger and is discharged into the engine cylinder through a self-closing valve 8. Formed on an extension of the plunger is a screw thread 19 which engages a corresponding thread on an outer fixed casing and on an extension 3 of the threaded part of the plunger is carried the injection nozzle a spring 18 serving to hold the plunger and its associated parts in their lowermost positions. The cylinder pressure forces back the moving parts which rotate by reason of the screw and nut connection. According to a modified construction, the nozzle is rotated independently of the pump and without moving upwards by a threaded connection with an annular piston. Also, the piston may move with the plunger. The Provisional Specification refers to Specification 366,500, [Group XXVIII].

Title: Zigzag stitch-forming mechanism for sewing machines
IPC: D05B3/02
Filed: 1937-08-20
Abstract: 483,533. Sewing - machines. FAIRWEATHER, W. C. (Singer Manufacturing Co.) Aug. 20, 1937, No. 22825. [Class 112] The invention describes means for vibrating the needle laterally suitable for incorporation into the buttonhole sewing - machine described in Specification 479,484. The main shaft 5 drives the vertical shaft 8 through the one-to-two bevel-gears 6, 7. The shaft 8 has a one-to-two bevel-gear driving connection 9 with the needle-bar reciprocating shaft 10 which has the usual crank 11 and link 12 connection with the vertically reciprocating needle-bar 13. The needle 18 is mounted in a block 16 sliding in a guide 26 ; the block has a channel C for permitting the needle thread, which passes down the hollow needlebar, to reach the needle eye. The block 16 is carried by a yoke 14 which is slidably received at one end in the guideway 19, Figs. 12 and 14, in a vertical arm 20 depending from the block 21 fixed to the lower end of the bushing 22 journalled in the head 4 and having a pinion 23 fixed to its upper end to permit the needle to be turned by the sector 129 worked in unison with the turret 65 then stitching round the eyelet end of the buttonhole. Depending from the block 21 is another arm 24 spaced from the arm 20. The arms 20 and 24 carry a cross pin 25 on which is horizontally slidably mounted a vertical guide arm 26 having a guideway 27 for the spaced rear extension 28 of the needle clamp block 16. The vertical guide-block 26, which imparts the lateral vibratory movement to the needle block 16 is connected by a link 32, Fig. 9, of adjustable length to an arm 33 fixed to one end of a rock shaft 34 journalled in the block 21 and having fixed to its other end an arm 35 which pivotally carries a guide-block 36 received in the circular groove 37 in the ring member 38 fixed to the lower end of the slide-rod 39, Fig. 1, journalled in the head 4. Vertical movements of the slide-rod 39 and ring 38 impart lateral vibratory movements to the needle 18. The rod 39 is reciprocated by the following mechanism ; block 41, link 43, arm 44 of the bell crank lever 44, 45, link 47, adjustable crank pin 48, head 49 pivoted at 50 and shaft 52. Movement of the crank-head 49 about the pivot screw 50 changes the eccentricity or operative radius of the crank 48 relative to the shaft 52. To compensate the shuttle mechanism for the different positions of the needle, the shuttle driving shaft 91 is accelerated or retarded by an eccentric 97 and lever 98, Fig. 3, with a forked lower end slidingly embracing the anchor block 99 of a rockable pin 100. Rotation of the main shaft 5 imparts oscillatory movement to the carrier 92 for the crank-shaft 91.
