Title: Improvements in or relating to lip turning machines for use in the manufacture of boots and shoes
IPC: A43D43/06
Filed: 1927-09-15
Abstract: 302,382. British United Shoe Machinery Co., Ltd., Ricks, F., and Richards, A. E. Sept. 15, 1927. Channel-opening. - Relates to lip-turning machines of the kind described in Specification 241,615, and consists in the provision of a work support and roll which co-operate in the feeding of the work, an outsidelip-engaging hammer reciprocating within and parallel to the axis of the roll, an inside-lip hammer giving blows alternating with those of the first hammer, and a second outside-lip hammer moving in a path perpendicular to that of the first. The latter two hammers operate in the projected circumference of the feed roll. The work is supported by a rotating table 1 urged upwardly by a spring but depressed to permit insertion of the work by a treadle rod 3. A feed roll 4 is driven, with the table., through a two speed gear changed as desired by a rod 10 connected to a, treadle, so that the straighter edges may be fed more rapidly than the sharply curved portions. The outside lip is raised by an adjustable plough in advance of the feed roll and shaped to turn up the lip into the path of a hammer 16 coaxial with the roll and reciprocated by a lever 23 oscillated by a crank 26 driven by a pulley 80. A vertical hammer 27 is reciprocated by a gear segment 29 also carried by the lever 23 and further sets the outside lip. A member 30 opens the inside channel and is adjustably carried by a lever 32. This lever is linked to an arm 40 formed with a lug 43 engaged' by a lug 42 on the lever 23 so that as the hammer 16 strikes the outside lip the member 30 is retracted, this being returned by a spring 37, the effect being that these two tools beat the work alternately on opposite sides. The lever 32 is also connected by a yielding link 46 with the table, so that as this is depressed for work insertion the member 30 is retracted. A slitting knife 54 reciprocates in a slot in the plough when a cam roll on an arm 57 is positioned in the path of a cam 59.. Hand or treadle means put the roll out of or into operative position as desired. For operating on " Gem " type insoles, in which the edge of the insole is split and one portion of the edge turned up and reinforced by a canvas strip, the hammer 27 is dispensed'with, and the tool 30 substituted by a tool with a flat smooth face bearing against the root of the lip.

Title: Improvements in or relating to electric clocks
IPC: G04C3/06
Filed: 1928-03-17
Abstract: 296,031. Conrad, F. March 17, 1927, [Convention date]. Divided on 287,182. Electric clocks; balances and pendulums, regulating electrically; actuation by condensers; motionwork. - In a clock in which the balance is electrically maintained in oscillation by electromagnets which act magnetically and directly on the balance wheel, the curb-pins used to adjust the effective length of the balance spring serve also as the contacts of the circuit, these latter alternately making contact with the spring in the to and fro oscillations of the latter, thereby completing the circuit of the magnets and charging and discharging a condenser. The balance staff 1, Fig. 1, carries a balance spring 2 anchored at 3, a balance wheel 5 having upright flanges 6, 7 and cut-out portions 8, 9, and members 17, 18 of opposite screw thread and extending partially round the staff 1. The ends 48, 51, 52, 53 of the flanges 6 and 7 coact magnetically with the poles 13, 14 of the magnets 11, 12. 'The curb-pins 40, 41 are adapted to close the electric circuit through the spring 2. As it expands this spring meets contact 40 and closes the circuit, energizing the magnets and charging the condenser 44. At this instant the poles 48, 52 are slightly nearer the poles 13, 14 than are the poles 51, 53 so that the magnets add to the oscillation of the balance in the same direction. When the spring contacts it touches contact 41 and discharges the condenser 44 through the magnets, again giving an impulse to the balance, but this time in the reverse direction. The condenser also prevents sparking at the contacts 40, 41. At the oscillations of the staff 1 the members 17, 18 alternately engage the wheel 21 so that the latter always rotates in the same direction; this wheel 21 drives shaft 22, worm 23, wheel 24, shaft 25, wheels 26, 27 and shaft 28, the other end 31 of which bears the minute hand. A wheel 32 on the shaft 28 drives the hour hand by wheel 33, shaft 34, and wheels 35, 36; wheel 36 being rigid with a sleeve 37 which is loose on a shaft 28 and carries the hour hand. When the hands are adjusted on their spindles the worm 23, being irreversible, prevents motion being transmitted backwards to interfere with the balance mecbanism. In a modification, Figs. 2 and 3, a balance staff 182 carries a balance 184 and hair spring 185 and an armature 186 which coacts with two coils 180, 181. Rigid contacts 194, 195 coact with a contact 193 carried resiliently on the staff 182 by a spring 191. These contacts coact, as do the contacts 40, 41, in Fig. 1, to charge and discharge the condenser 106.

[Also in Group XXXVIII] In a centre-post type record changer, a plurality of push buttons 7 to 9 controlling the selection of driving speeds also effect the release of a cycling cam-disc 59 which in turn controls a scanning finger which determines the size of the record to be played and sets down the pickup accordingly. The turn-table is driven by means of a removable jockey pulley 23 which effects engagement between the inside of the rim of the turn-table 2 and a stepped motor shaft 20. The pulley 23 is raised and lowered under the control of a lever 31 having a notched end-plate 33 which causes the pulley 23 to be raised a maximum amount when button 7 is pressed, a lesser amount when button 8 is pressed and not at all when button 9 is pressed. Each of the buttons becomes latched down by means of a stirrup 40, Fig. 5, which engages a notch 48 in the appropriate push-rod 41. Operation of a stop button 6 releases the operated button 7, 8 or 9 so that driving contact of the pulley 23 is broken.

Title: Improvements relating to the production of fibres or filaments by the funnel spinning method
IPC: D01D5/14
Filed: 1953-09-04
Abstract: <PICT:0745098/IV(a)/1> <PICT:0745098/IV(a)/2> <PICT:0745098/IV(a)/3> Apparatus for the production of artificial filaments or fibres by the funnel spinning method comprises an annular channel for conducting precipitation liquid to the spinning funnel and one or more coil rings arranged within the annular channel so as to prevent or minimise turbulent movements of the precipitation liquid in the vicinity of the spinning nozzle.  The coil rings may also serve as spacing members between the spinning funnel and an outer casing.  For this purpose, the ratio of the diameter of the loops to the diameter of the wire of the coil should preferably not exceed 10 : 1 for soft - annealed chrome-nickel wire, or 15 : 1 for harddrawn refined steel wire.  In the case of wire made of a synthetic plastic material this maximum ratio may be 5 : 1.  When water is used as the precipitation liquid, the loops may be spaced at a distance of up to 1 m.m.  If the diameter of the outer casing is much larger than that of the funnel it may be necessary to have intermediate members in the annular channel surrounding the spinning funnel in addition to the coil rings. As shown in Fig. 1, a spinneret 1 is disposed just above a spinning funnel 2 which is surrounded by a casing 3. Precipitation liquid flows from an inlet 4 into the annular channel 5 in which there is arranged a coil ring 6 which prevents turbulent flow of the liquid as it enters the top of the spinning funnel and which at the same time spaces the funnel from the casing.  A wire coil ring 6 is shown in Fig. 2.  As shown in Fig. 4, the spinning funnel 2 has no outer casing and the precipitation liquid flows through conduit 10 in a cylindrical vessel 9 which is disposed above the spinning funnel. The supply pipe 11 for the spinning solution extends into vessel 9 and is surrounded by a sleeve 12.  Coil rings 6 are arranged between the sleeve 12 and the inner wall of vessel 9 so as to prevent turbulent flow of the precipitation liquid as it passes close to the spinning nozzle and enters the funnel.
