Title: A weight variation warning device for use with textile machines having automatic hopper feeds
IPC: D01G23/04
Filed: 1958-07-16
Abstract: 920,493. Automatic feed weighers. M. P. FOX. July 15, 1959 [July 16, 1958], No. 22810/58. Class 143. In automatic feed weighers of the kind in which loads are discharged at regular intervals of time by the use of a timer with cams which control the sequence of events in each weighing cycle, it is desirable that the weigh beam tilt within a predetermined correct period within each cycle. The invention provides an alarm device for attachment to such weighers whereby audible or visible warning is given of all weigh beam tiltings occurring outside the correct period. The device comprises a cam or cams adapted to be driven in synchronism with a cam of the timer, the or each cam of the device operating a switch to provide the alarm, the latter being actuated whether the tilt is early or late. The invention is described as used to control the feed of textile fibres in an apparatus which delivers the fibres from a hopper to a weighpan discharged by tipping (Fig. 1, not shown) in cycles under the control of a timer. In one form (not shown), the device according to the invention comprises two cams spaced apart circumferentially on a common shaft and two associated switches, one of which operates an early tilt alarm and the other a late tilt alarm, the said alarms being differently coloured lamps. The power supply to the lamps includes a further switch which is made momentarily when the weighbeam tilts and, if the late or early tilt alarm cam is then operating its switch, causes the appropriate alarm to be given. In the form shown the device comprises an arm 43 which descends with the weighpan and carries a feeler 34 which, if the tilt occurs outside the correct period, engages a flange 37 on a cam 33 of the device but which, if the tilt occurs within the correct period, enters a gap 38 in the flange. When the flange is engaged by the feeler, the latter operates a switch energizing the alarm lamp 44.

Title: Improvements in machines for slotting the heads of screws and the like
IPC: B23G9/00
Filed: 1925-09-14
Abstract: 239,887. Spengler, E. Sept. 12, 1924, [Convention date]. Screws.-In an automatic machine for slotting screw-heads, the screws are lifted from mass assemblv in a shoot and conveyed to a slotting saw. The screws are lifted one or more at a time from the shoot 1 having three downwardlyconverging sides, by a sector-shaped plate 2 having an adjustable recess 7 to receive the screwshanks and attached to a laver 3 oscillated about a pivot 4 by a cam 5 and a weight or spring 3<1>. The plate 2 oscillates through an opening in the base of the shoot and raises the screws until a second sector-plate 8. attached to a lever 9 oscillated by a cam 10 and a weight or spring 9' receives them singly in a recess 11'and conveys them to the rotating saw 14. The sectors are raised by the weights &c. and depressed by the cams so that no damage will ensue should the screws jam. The recess 11 is bevelled at the end to prevent more than one screw from entering and the sectors 2, 8 oscillate in opposite directions. At the end of its upward stroke the sector 8 forces the screw-head into a guiding orifice 13 in a lever 12 which steadies it during cutting, the depth of cut being limited by a stop 22 engaging the lever 9. On the return stroke a pivoted member 21 engages the end of the screw to remove it from the recess 11 and a spring 15 returns the lever 12. The speed of the slotting-saw may be varied and an intermediate inclined shoot may be fixed between the sectors down which the screws slide by gravity. The cutter-spindle 17 may be adjusted axially to position the saw in the middle of the screw-heads by means of two nuts and lock-nuts on the spindle.

Abstract: 878,570. Glass forming and blowing apparatus. OWENS-ILLINOIS GLASS CO. July 23, 1958 [July 25, 1957], No. 23619/58. Class 56. In a two-stage blank-forming and blankblowing apparatus in which a blank mould receives a molten gob and a split neck mould is alignable with the blank mould and moves arcuately to transfer a formed blank from the blank-forming station to the blank-blowing station, springs means are arranged to constantly urge one neck mould section into engagement, and fluid pressure actuated pistons supplement the spring means and urge the neck mould sections together at the blank-forming station but oppose the spring means and urge the sections apart at the blank-blowing station. In a machine embodying the invention, parisons formed in a blank mould unit 10, Fig. 2, from molten gobs supplied through shoots 252 are swung over and inverted into an upright blowing position in a blow mould unit 12 by split neck ring 15. The blank mould initially moves vertically and is subsequently displaced arcuately about the vertical axis 32 to increase the neck mould-to-blank mould clearance when the neck mould is moved arcuately about horizontal axis 220 to the blank-blowing station. The neck rings 15 are held closed under pressure provided by springs 237, 237a, Fig. 6, which, at the blank-forming station is supplemented by pressure from sleeve members 224 and 224a which are actuated by air pressure through conduits 239 into chambers 219, 219a. When pressing is completed at the blank-forming station and at about 90 degrees of the transfer movement of the parison to the blank-blowing station, the supplementary pressure is released. On arrival at the blankblowing station the neck rings 15 are opened by the admission of air through channel 241 into chambers 243, 243a which causes sleeves 224 and 224a to move away from each other and to open the neck rings by sliding them along splines 162 and 162a. The blank mould has baffles 148 which are displaced vertically prior to displacement of blank mould. Coolant air is supplied to the hollow interior of baffles 148 through hollow arm 154. The arms (e.g. 153) carrying the two partible sections of the neck mould 15 are also hollow and a part of the air which is used to produce the moulding pressure of the sections is by-passed and directed into the neck mould for cooling. This application of cooling air continues through a portion of the transfer of the parison and also prior to the return of the neck mould to and during the pressing operation. The walls of the blank mould are surrounded by a cylindrical perforate sleeve, (not shown), for directing coolant air in pre-determined amounts and in patterns varying axially with respect to the elongated blank mould, the blank mould being carried by a hollow arm, (not shown), which directs air to the perforate sleeve. A sleeve may be replaced by a similarly sized sleeve having different perforation patterns to vary the amount of air directed against any portion of the mould walls.
