Title: Improvements in or connected with yarn or thread winding machines
IPC: D01H1/20
Filed: 1929-05-23
Abstract: 338,889. Gribojedoff, N., and Spiral Spindle (S.S.) Co., Ltd. May 23, 1929. Divided on 338,861. Winding - machines; driving - arrangements; spindle-driving apparatus. - In a machine for winding yarns and threads a number of spindles adapted to carry cops or the like to be wound are disposed around the periphery of a central rotary operating device arranged simultaneously to impart rotary and vertical reciprocatory motion to all the winding spindles or to intermediate spindles through which the winding spindles are rotated. In a machine of the former type the winding- spindles 21, Fig. 2, are disposed equidistantly round a rotating member 7, Fig. 1, having a camthread 8 adapted to engage grooved pulleys 9 on vertical shafts 10 which are provided with grooved wheels 19 engaging members 20 through which the spindles 21 are rotated and traversed. The pulleys 9 comprise independent halves 13, 14 pressed together by springs 15, Fig. 3. The spindles 21 are slidable in bearings 23 carried at the ends of fixed arms 24. In a machine of the second type adapted for winding cylindrical packages, each shaft 10 which is rotated and reciprocated vertically through a pulley 9 is provided with two grooved rollers 51, 52, Fig. 3. adapted to rotate the packages carried on spindles 53 and to traverse the yarn thereon. In a modification of this type, a roller 61 having a central cam thread 60, Fig. 5, on each shaft 10 is adapted to drive grooved rollers 56 on reciprocable spindles 57, the wound thread being guided in grooves 59 on to the packages carried on spindles 62. Dust from the machine is sucked through meshwork 2, Fig. 1, by means of a fan 3 on the shaft of the driving motor 4. Specification 338,861 is referred to.

Abstract: 795,430. Capsuling bottles. NATERMANN, L., and NATERMANN, I., [trading as HAENDLER & NATERMANN, OHG.]. Aug. 27, 1956 [May 26, 1955], No. 26018/56. Divided out of 777,890. Class 125(2). In apparatus for applying sealing cups, e.g., of metal foil, to bottles 2, the bottles are fed by a conveyer 1, Figs. 2 and 4, to an arcuate plate 5 around which they are carried by a crown wheel 4 past a device 6 which gums the bottle neck, apparatus for feeding obliquely a cap piece 9 from a supply roll 7 and including a feed roll 8a and a cutter 8b and a device 12 for tacking the cap piece to the bottle, the bottle then passing a rotating brush 13 which smooths down the cap, the bottle being rotated during this stage. As shown in Figs. 1 and 2, the bottle is returned to conveyer 1 before reaching device 13 and is rotated by being pressed against resilient wall 14 by a moving belt 15. As shown in Fig. 4, device 13 is disposed around arcuate plate 5 and the bottles are rotated during all operations by being pressed against resilient wall 33, the crown wheel 4 having rollers 32 which allow this rotation. The cap pieces may be cut with straight or curved edges. Holders 10, 11 on the crown wheel 4 are opened and closed by cam means to hold the cap pieces until they are tacked on to the bottles.

Title: Improvements in the suspension means for vehicles
IPC: B60G11/14
Filed: 1945-10-05
Abstract: 644,851. Vehicle spring-suspensions. GREGOIRE, J. A. Oct. 5, 1945, No. 26047. Convention date, May 24, 1944. [Class 108(ii)] In a vehicle suspension of the type which comprises a coiled spring 5 interposed between a pivot on the chassis frame and an intermediate point 6 on a wheelcarrying lever 3 pivoted to the frame 1, the axis of the spring being disposed at an angle to a line connecting the respective points on the lever at which it is connected with the frame and the spring, this angle increasing with the load, the free length of the spring substantially equals the difference in length between the respective distances from the point of connection of the lever, with the frame to the two ends of the spring. As shown in Fig. 2 the link 3 is free to move through 60 degrees corresponding to the range of positions between fully loaded and unloaded conditions. In Figs. 5, 6 (not shown) this angle is 45 degrees. The ratio of the distance 2-6 and 2-7 preferably lies between “ and <SP>2</SP>/ 3  but in Fig. 3 (not shown) is greater than unity. The tension springs shown, may be replaced by compression springs. The suspension may be incorporated with a conventional type of constantrate suspension. The Specification as open to inspection under Sect. 91 comprises also the use of other springs, e.g. rubber or pneumatic. This subject-matter does not appear in the Specification as accepted.

Title: Safety belt buckle
IPC: A44B11/25
Filed: 1963-07-02
Abstract: 1,039,723. Latches. R. C. FISHER. July 2, 1963 [July 3, 1962], No. 26137/63. Heading E2A. A safety belt buckle 10 comprises a base member 12 of channel section and having a latch plate retainer 50, and also a web portion 40 with upstanding flanges 42, 44 on opposite sides with inturned edge portions 46, 48, a latch plate 14 with a latch face 90 thereon, a belt tongue 30 having a latch surface 92 thereon, resilient means 16 normally biasing the latch plate towards the tongue and a release handle 18 pivotally supported by the base member 12 and operable to effect release of the belt tongue 30 from the base member. As shown, the latch plate 14 is positioned in the base member by the engagement of ears 60, 62, struck from the base member, with cut outs 64, 66 in the latch plate, whilst further ears 70, 72 in the base plate retain a rear slide 22 and position the handle 18 and the latch plate. A belt bar 20 is supported by a pair of ears, 120, on the slide 22, which extend inwardly from a downwardly depending rear portion 124 of the slide. The bar is retained in a pair of apertures 130, and is of generally pear-shaped cross-section with flattened end portions 134, 136 projecting into the apertures 130. The end portion of a belt 36 is looped over the bar 20 and extends downwardly through an aperture 80 in the base member 12 such that when the buckle is under load, an edge portion of the bar 20 overlies an edge portion 142 defining in part, the aperture 80. A rib 144 in the base member precludes slip of the belt when the buckle is subjected to severe loads. Adjustment of the belt is effected by moving the slide 22 inwardly and tilting and pulling the buckle relative to the belt for lengthening the belt, and pulling on the end portion of the belt which rotates the bar 20 so that the end portions 134, 136 thereof engage the upper edges of the apertures 130, for shortening the belt.

Abstract: 480,027. Thermal switches. TRICO PRODUCTS CORPORATION. Sept. 29, 1936, No. 26445. Convention date, April 24. [Class 38-(v)] [Also in Group XXXVIII] A thermal switch comprises a U-shaped contact arm 6 having knife edge bearings in pillars 7 on the metal base 1 and biassed by a tension spring 10 into engagement with a fixed contact 4. A taut wire 13 is fixed at one end to an abutment 15 and is electrically connected with the contact 4 while its other end is fixed to an adjustable abutment 16, and is electrically connected through base 1 to the movable contact arm 6. An insulating link 22 connects the wire 13 and spring 10 so that when the wire is cold the contact arm 6 is held in the open position. Current is lead in by a lead 18 and passes through wire 13 and out of a second lead (not shown) connected to the base 1. The heated wire slackens and spring 10 moves across deadcentre to snap arm 6 into engagement with contact 4. The wire 13 is then shunted and cools causing the spring 10 to move down again and open the contacts 6, 4. The switch, shown at 23, Fig. 1, is described as connected in series with the stop lights 21 of a motor vehicle, and energized through a switch 30 operated on depression of the brake pedal 31.
