Filed: 1941-07-10
Abstract: 552,559. Combing-machines. NASMITH, J. W. July 10, 1941, No. 8685. [Class 120 (i)] In a combing machine of the rectilinear type the top comb is solidly mounted in a carrier which is driven and controlled so that the point of oscillation of the comb is changed from one pivot to another and the comb moves along two different arcuate paths, the movement along one path taking it to the point of its penetration into and ultimate withdrawal from the fibre tuft while between that point and the detaching rollers and while engaged in the tuft it moves along the other path; means may be provided for varying the throw of the comb in its oscillation to and from the detaching rollers. As shown the top comb 3 is carried by a bridge 4 securely screwed to an arm 5 having a projection tapered to receive a screw 7. A part 5a of the arm 5 also carries an adjustable screw 9 adapted to engage a bowl 11 on a fixed pin 12 on which is pivoted an arm 13 carrying a bowl 14 adapted to engage the screw 7 and connected to an arm 15 upon the setting shaft 16. The comb is oscillated from a three-armed lever 17 rocked in the usual manner on a shaft 18 and connected by a bolt 20 to a slotted lever 23 on a shaft 24 carying a lever 28 connected by a forked rod 29 to a pin 30 on the comb arm 5; by adjusting the bolt 20 in the lever 23 the throw of the top comb may be adjusted. As the top comb is rocked and moves backwards it oscillates on the pivot 12 and engages the fibre tuft while moving along the are A, the depth of penetration depending on the adjustment of the screw 9; as the backward movement continues the screw 7 engages the bowl 14 and the comb pivots about that bowl and moves along the arc A<SP>1</SP> the screw 9 having lifted from the bowl 11. The forward oscillation of the comb causes it to move along the archs A<SP>1</SP>, A, the point A<SP>11</SP> giving the point of penetration and withdrawal of the teeth of the comb from the fibre tuft and by rocking the shaft 16 the arm 13 at each head of the machine can be adjusted to vary the distance between the bowl 14 and screw 7. and so the points of penetration and withdrawal. Specification 132,987, [Class 120 (i)], is referred to.

Abstract: 472,804. Rolling metal bands. DOUBS, J. March 24, 1937, No. 8737. [Class 83 (iv)] In a process for hot rolling wide metal bands in a reversible mill, the work is first preliminarily rolled to strips of predetermined length which are stacked in a reheating furnace while the mill is converted to a finish-rolling mill, whereupon the strips are withdrawn singly, rolled to the final thickness and received on winding rollers. The blooms are heated in an oven 1 and then passed edge-on through a descaling machine 2, and then through an edge-rolling mill 3. The work then passes to a four high mill 4, driven bv a reversible motor 5 and is rolled backwards and forwards with simultaneous edge rolling which may be effected by mills arranged in front of and behind the four high mill. The strips which are then about 10 mm. thick and 15-20 metres long, are then pickled if necessary and transferred along a conveyer 7 to an oven 9. A new set of finish rolls are now placed in the mill 4, and the strips removed singly from the oven and passed through the finish mill to a winding device 10. The mill is then reversed and the work re-rolled and wound on a second winding device 10a rotating in the same direction as the winder 10. Both winding devices are heat insulated and have pivoted inlet gates and before the fourth pass the gate of the winder 10a is lowered and the band is delivered to a cold winding device 11 or in cut into strips by shears 12. When the last strip has been removed from the furnace 9, cycle is recommenced on another batch of blooms from the oven 1.

Abstract: 291,189. Croad, A. K., (Brase. W.). March 31, 1927. Portable sewing - machines; lock stitching by shuttles; needles, driving; frames.-A toy sewing-machine has its parts made from sheet metal stampings; the needle bar is operated directly by a pivoted and reciprocating lever, which also operates the shuttle driver by an intermediate link. The needle bar 9, formed by bending a blank to a square cross-section, has a pin 10 working in a slot 11 in the actuating lever 12, pivoted at its end to a link 14 which in turn is pivoted to the link 18 carrying the shuttle driver 19. The link 14 is pivoted on a rod 15, an extension of which forms the pillar for the bobbin 17. To form a stitch, the lever 12 is pulled outwards when in its fully depressed position, shown in broken lines in Fig. 1, when the cam 26 riding up the lower edge of a slot in the slide 7 imparts a direct upward pull in the needle 29 to form a loop. On lifting the lever 12 to the end of the slot, the shuttle is pulled through the loop so formed and the needle lifted. Depression and pushing of the lever 12 brings the parts into position for making the next stitch. A pin 28 on the arm 12 rides round a cam 27 on the casing to prevent any wrong movements. The shuttle 44, Fig. 10<a>, is made of sheet metal and carried in a blade spring 43 of a sheet metal holder 20 carried in the holder 19 of the lever 18.

Filed: 1927-04-02
Abstract: 268,825. Brooke, R. G. April 3, 1926, [Convention date]. Giffard injectors; controlling action. The valve 14 which controls the low pressure steam inlet 11, Fig. 5, is held open mechanically, e.g. by the spring 21, but is held closed by means, e.g. the piston 24, operated by the high pressure steam, which is admitted automatically when the injector is not working or when the low pressure steam falls below a predetermined value. The high pressure steam is admitted through the branch 31 while 49, Fig. 1, is a second low pressure inlet. To start the injector the control valve 34, Fig. 2, is screwed back from its seat 35 on to its second seat 34<a> and, exhaust steam being available, the parts occupy the positions shown in Fig. 1, high pressure steam passing from inlet 31 to inlet 32b and from chamber 32<a> to chamber 42, the valve 44 closing passage 43 and the valve 14 being open. Should the exhaust steam fail or drop in pressure, the high pressure steam will open the valve 44, move the piston 38, which has a lost motion connection with the spindle 37, and open the valve 36 to admit steam through chamber 35<a> to exhaust steam chamber 33<b>, and also through passages 50, 51, 53, 54, 55 and pipe 26 to piston 24 to close the valve 14. When the valve 34 is closed the non-return valve 52 prevents steam passing to chamber 35<a>, but steam still passes to piston 24 to keep valve 14 closed. The live steam and exhaust steam cones may be of the type described in Specification 219,041.
