Title: Improvements in or relating to sewing machines
IPC: D05B35/12
Filed: 1960-08-18
Abstract: 938,505. Sewing-machines. G. M. PFAFF A.G. Aug. 18, 1960 [Nov. 24, 1959], No. 28591/60. Class 112. A buttonhole sewing machine 1 has a frame 14 on which work is clamped, the frame being both pivotable about a bar 32 to accommodate the movement of the work due to the action of the feeding foot 6 and movable along the axis of the bar 32 to index the work between buttonholes. The buttonhole sewing machine has a starting lever 10 operated by an electromagnet 9, while raising of the feeder foot lever 7 is effected by an electromagnet 8. Feed by clamps.-The frame 14 comprises end bars 33, 34 connected by the bars 32, 38 and 52. Work-holding clamps 40 mounted on the bar 38 are openable in unison by a slide 41 moved by a cable 43 on depression of a pedal bar 44, or may be opened manually. Guide rollers 93, attached to a member 90 connected to the lever 7, embrace a bar 94 secured to the bar 38 to swing the frame about the bar 32 as the lever 7 and feed foot move. The bar 32 is carried for rotation and axial movement in rollers 49 (see Fig. 3), the upper pair of which are adjustably mounted on eccentric bolts 48. A chain 50 stretched between the end bars passes over a sprocket 22 driven to move the frame parallel to the axis of bar 32, through a slipping clutch from the shaft 18 of a feed motor. A ratchet wheel 21 secured to the shaft is engaged by pawls 56, 57 when the feed of the frame is to be stopped while a buttonhole is being sewn. The motor sprocket and clutch are mounted on the fixed plate 16, which also carries linkage 65, 69, 76, 80 co-operating with an electromagnet 60 and with cams 53 adjustably mounted on the rod 52 to provide automatic indexing of the frame between buttonholes. Operation.-After the completion of the first buttonhole the lever 10 actuates a switch 12 on the machine to energize electromagnet 8 and, momentarily, electromagnet 60 to respectively raise the feeding foot and rock the lever 65 about its pivot 64. The switchbar 69 is thus raised, its pin 86 raising the lug 84 on the cut-off finger 80 clear of the cam 53. As the bar 69 rises its upper end engages the pawls 56, 57 and lifts them clear of the ratchet wheel so that the feed motor may rotate the sprocket 22 and drive the frame until the material is correctly disposed for the next buttonhole. The spring 81 draws the locking slide 76 to the right to position its projection 75 below the end 73 of the raised switchbar 69, where it prevents the bar from falling to its previous position when the electromagnet 60 is de-energized, finger 80 being in its position of rest. The next cam 53 then engages the lug 84 to move the locking slide. 76 to the left to allow the bar 69 to fall and engage the pawls with the ratchet wheel. Reversing cams 55 engage with reversing switches 87, 88 to reverse the motion of the frame at the end of the series of buttonholes.

Title: Adjustable forming bag for garment finishing machines
Inventor: JACKSON NOLAN CLAIR
IPC: D06F73/00
Filed: 1955-10-07
Abstract: 790,661. Garment drying and/or finishing. WICHITA PRECISION TOOL CO., Inc. Oct. 7, 1955, No. 28690/55. Class 34(1) In a garment finishing machine comprising an inflatable flexible bag 14 for supporting a garment, the diameter of the bag when fluid under pressure is admitted thereinto to inflate it is controlled by means of at least one expansible loop 20 attached to the bag 14 intermediate the ends thereof, due to the resistance of the expansible loop to the fluid pressure. The bag 14 is of permeable material e.g. fabric, and is inflated by hot air and/or steam pressure. In the example three loops 20 are provided each loop comprising a continuous coil spring mounted in a continuous flexible tube 22 stitched to the bag 14 as at 24. The spring loops 20 are each contained in a continuous inflatable conduit 28 made of rubber or other expandable material and in the form of a bellows. The pressure of the fluid supplied to the bag 14 is preferably insufficient to expand the spring loops 20, thereby maintaining the diameter of the bag adjacent each loop 20 fixed. If this diameter is too small to properly form the bag 14 in accordance with the shape or size of the garment being treated the conduits 28 must be inflated to expand them. Each conduit 28 is 'therefore connected by a hose 38 through a control valve 40 to an air or other fluid supply pipe 34. A valve 52 controls the flow of fluid under pressure through a hose 50 to sleeve members 42 of the bag 14, each sleeve 42 comprising a bellows like inflatable conduit containing an elongated coil spring 48. Modifications. Instead of a continuous coil spring each loop 20 may comprise a pair of coil springs connected at their end (Fig. 3, not shown). In a further modification (Fig. 4, not shown) each loop 20 comprises a continuous coil spring of appreciably smaller diameter than the surrounding bellows, and the nature of the material from which the bellows is made is such as to normally be contracted and have sufficient force to hold the spring in a contracted condition.

IPC: H02K9/10
Filed: 1919-11-20
Abstract: 159,282. Smillie, J., and Metropolitan- Vickers Electrical Co., Ltd. Nov. 20, 1919. Ventilating machines; inlet and outlets ports, arrangements of; air, cooling; valves and valve apparatus actuating.-In ventilation apparatus for electrical and other machines in which passages communicating with ports in the machine are controlled by doors which enable the air to circulate in a closed circuit through a cooling device, or in an open circuit to and from the atmosphere, the doors are mechanically connected for simultaneous operation; in a modification, a single door is used. Figs. 1 and 2 show one form in which during closed circuit operation air flows out from the machine through the passage 3 to the cooler 5 and back through the passages 9, 11. On open circuit, atmospheric air passes from conduits 12, 13 to the passages 9, 11, and from the outlet channel 3 to lateral passages 14, 15 back to the atmosphere. The change-over is effected by pivoted doors 16, 17, 18, 19, which on closed circuit close the entrances to the passages 12, 13, 14, 15, and open communication between the channels 9, 11 and the space 6 in front of the cooler. On open circuit the channels 12, 13, 14, 15 are opened, and direct communication between the space 6 and the channels 14, 15 is cut off. The shafts of the four doors are connected by bevel gears, so that the hand lever 20 operates all the doors simultaneously. In modifications, the bevel gears are partly or wholly replaced by link connections; and in other modifications the arrangement of the passages to and from the atmosphere is varied; or two controlling doors only are employed, connected by links. Fig. 12 shows the use of a single door 56, which on closed circuit is in the vertical position and cuts off the channel 55 leading to the atmosphere; air then passes from the channel 3, through the cooler to the passage 11, part entering the passage 9 through ducts 51 on each side of the passage 3. On open circuit, the door 56 is horizontal, and divides the passage 55 into two parts, the upper of which acts as an outlet and the lower as an inlet; at the same time the communication between the space 6 and the passage 11 is closed.

Abstract: 675,000. Indicating volume of liquid. MULLER, B. M. Nov. 14, 1950 [Nov. 14, 1949], No. 29105/49. Class 123(i) The total volume of liquid in one or a number of fuel containers, even when tilted as in aircraft, is indicated by four dip tubes 11 in the liquid fuel each leading to a side branch 13 of a (mercury) manometer 14 the average depth being thus obtained in the central tube 15 of the manometer and indicated on a pressure gauge 23. The tube 15 also has a dip tube 19 supplied with pressure air from 18 through a surge preventing flow restrictor 29 whereby the level of mercury in 15 varies the air pressure in tube 21 leading to a sealed chamber 22 provided with a flexible diaphragm forming part of the pressure gauge 23. In Fig. 2 a number of tanks 36-41 each has four dip tubes leading to its own manometer 44. A dip tube in the centre tube of each manometer also has a pressure air supply and flow restrictor 51 and is connected by 48 to a selector valve unit 49. The selector valve unit may be individually or simultaneously connected to the manometer tubes 48 by hand manipulating the selector valve unit 49. Conduits 52 from 49 lead each to one of six concentric annular chambers 53 of equal cross-sectional area in a main mercury manometer 54 the pressure in the dip tube in the central chamber 55 operating a volume (pressure) indicating gauge 35 in the same way as in Fig. 1. The manometer 54 comprises concentric chambers 53, Fig. 3, and a central chamber 55 all closed at their upper ends. Conduits 59 from 55 are from the centres of 44 and from the tanks 36-41 and also from the pressure gauge casing 35 lead to a common vent at atmospheric pressure or a constant low air pressure. The selector valve unit can be set to connect one or more of the manometers 44 to the main manometer 54 so as to measure the contents of any one tank or the total of a selected number of tanks. To prevent loss of mercury if the aircraft is flown upside down the dip tubes may be fitted with porous ceramic plugs which allow air but not mercury to pass through. Such plugs may also be fitted in the vent pipes from'the manometers. For tanks in which the horizontal cross-section varies from top to bottom, the centre tube 61 of the mercury manometer is fitted with a core, shaped in correlation with the shape of the tank to give accurate readings of the volume. The minimum effective cross-sectional area of the central tube 61 should be greater than the total cross-Sectional area of the side branches: The apparatus may be used for bag tanks the dip tubes being small diameter flexible pipes secured at the top and bottom wall of the tank by fittings including external and internal plates clamping part of the walls between them. To avoid inertia effects due to vertical acceleration the gauge indicator may be designed accordingly.
