Abstract: 1,121,243. Knitting-machines. SINGER CO. 30 Jan., 1967 [1 Feb., 1966], No. 4356/67. Heading D1C. A stitch sewing machine for producing a warp knitted structure such as a border attached to the edge of a fabric or a connection between two adjacent fabrics whereby they are secured together, comprises a row or rows of yarn carrying eyed needles 32A ... 32D, Fig. 6, which penetrate the fabric or fabrics and have their yarns engaged by yarn loopers 60A ... 60C which receive an orbital motion in timed relationship with the needle movement whereby loops are drawn out on the underside of the fabric or fabrics as it or they are advanced and the needles accordingly shogged to penetrate the loops in adjacent rows whereby the warp knitted structure is produced. The needles are arranged in two rows 32, 32<SP>1</SP> and receive a reciprocatory movement from a driven shaft 16 via a crank and link 34 coupled to a vertical needle bar 30 to which the needles are attached in a clamp 31. The bar 30 is journalled in a plate 26 which is secured to a shaft 25 carrying a barrel cam 50 at its opposite end and which engages a fixed follower. The shaft 25 is driven from a shaft 16 by a belt 52 whereby in time relationship with the vertical needle movement the shaft 25 under the influence of cam 50 is caused to be shogged and consequently shog the needles in both directions along their rows and transversely to the direction of feed of the fabric. The fabric is fed beneath a presser foot 95 containing a stripper foot 98 which holds the fabric down on retraction of the needles. The needles penetrate the fabric and then pass through needle apertures 92 in a throat plate 91 which is supported in the work supporting bed 11. Work feed dogs 94 reciprocated by a cam 118 on a shaft 18 driven from the shaft 16 advance the fabric in cooperation with the needle movement. Two rows of loopers 60, 60<SP>1</SP> are mounted on a block 61 driven on an orbited path by eccentrics secured to a plate 76 carrying the block 61. The eccentrics are driven through gearing from shaft 18. The movement is such that after the needles have descended the loopers engage the loop of yarn extending alongside their shanks and draw it out into a loop whereafter the needles are raised and shogged one needle space to either side and descend to penetrate an adjacent loop whereupon the looper releases the existing loop and rotates to reengage the yarn of the corresponding needles and the sequence is repeated.

Title: Improved method and apparatus for braking tramcars and the like vehicles
IPC: B61H7/02
Filed: 1929-02-12
Abstract: 325,684. Baker, W. S. Graff-. Feb. 12, 1929. Electric and magnetic; fluid-pressure; skid. - In brake apparatus for vehicles wherein pressure can be applied to brake shoes by air pressure and also by pressure from an electric or magnetic brake the pressure from the brake is applied in series with tne air pressure. In the construction described, the drag of magnetic track shoes is. transmitted to wheel shoes through the air brake cylinder which applies the wheel shoes so that the pressure on the wheel shoes due to the track shoes is effective only to the extent that it exceeds the air pressure, thus avoiding excessive pressure on the wheel shoes. Shoes 5, 6 for engaging a drum 4 on the axle 3 are suspended by links 6a, 7 from fixed brackets 14, 17. The shoes are applied in an equalized manner by a lever 9 connected to the piston rod 11 of the brake cylinder 12 to the pivot 15 of the shoe 5 and at its lower end 20 to a rod 8 connected to the link or lever 7. The cylinder 12 is mounted on 'an arm 25 secured to a shaft 23 carrying a second arm 24 connected to a member 32 to which is secured a slotted guide member 35 supported by a shaft 34. A lever 33 on the shaft 34 disposed between lugs 40 on the electromagnetic track shoe 21 is adapted to engage also projections' 39 on the member 32. When compressed air is admitted by pipe 45 to the cylinder 12 the shoes 5, 6 are applied to the drum 4 and if thereafter the track shoes 21 are energized, pressure is applied to the cylinder 12 by the drag of these shoes on the track through the lever 33 and member 32 and if this pressure exceeds the air pressure in the cylinder, the excess of pressure is transmitted to the shoes 5, 6. The shoes 5, 6 may be applied by hand through the rod 44 connected to the lever 33. The shoes for the wheel 1<a> of the truck are similarly associated with the track shoe on the far side of the track.
