Title: Work clamp mechanisms for sewing machines
IPC: D05B3/06
Filed: 1930-06-21
Abstract: 352,699. Buttonhole sewing-machines. FAIRWEATHER, W., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) June 21, 1930, No. 18969. [Class 112.] The work clamp cf sewing machines of the group-stitching type has main and supplementary clamp-levers on a lower clamp member, a clamp-foot carried by the supplementary clamp-lever, automatic means for operating said main-clamp lever and manually means for operating the supplementary clamp-lever. The invention is illustrated as applied to the machine of the type described in Specification 335,846, [Class 112, Sewing &c.], in which a reciprocating and laterally vibrating needle 5 co-operates with a shuttle 6 making " straight" buttonholes. The period of operation of the stitch-forming mechanism is controlled by the usual stop-motion device 8 .. 11. The work is held in a clamp moved longitudinally and laterally over the bed 1 by the usual-connections with the feed wheel, to place the stitches round the buttonhole. The clamp comprises the lower-work supporting plate 21 and upper clamping foot 22, which is carried by a supplementary lever 24 below the main upper clamp lever 23. Both levers 23, 24 are independently fulcrumed on the pin 25 fixed in ears on the lower clamp plate 21. A block 29, apertured to rock on the pin 25, is fixed to the lever 23 and lugs 31, similarly apertured to rock on the pin 25 and fixed to the lever 24. A weak spring tends to keep the lever 24 in contact with or parallel with the main lever 23. The tail 23<1> of the lever 23 extends under a roller-stud 35 associated with the stop-motion shaft 40. The lower clamp member 21 carries a vertical post 51 passing through holes in the levers 23, 24. This post has a strong spring 54 which presses downwardly on the clamp lever 23 and forces the clamp foot 22 into engagement with the work. A pulldown chain 46 forces the roller stud 35 downwards on the dial 23<1>, raising the front end of the clamp lever 23 against the spring 51 to open the work clamp.

Filed: 1925-07-27
Abstract: 247,835. Soc. Anon. de Commentry, Fourchambault, et Decazeville. May 8, 1925, [Convention date]. Heat and temperature coefficients, apparatus for determining. - In apparatus for measuring the thermal expansion of solids, a rod of the test material and one of a standard material are heated together to the same temperature and the difference between their expansions is transmitted to a recording-pen. The standard rod E<1> and test rod E<2> are mounted in silica tubes T<1>, T<2> secured to a plate 1 and their expansions are communicated by silica rods t<1>, t<2> passing through the plate, to plungers 3, 4 the outer ends of which bear on points 11, 12 on levers L', L2. The upper ends of these levers are provided with points p<1> - - p<2> which bear on supports secured to the plate 1 so that the levers are free to turn about horizontal axes under the restraint of springs 13. The movements of the lower ends of the levers are compounded by means of a plate B having bearing points a<1>, a<2>, a<3>, Figs. 10 and 11, at the angles of a right-angled triangle. The point a<2> bears in a recess in the end g<1> of the lever L<1>, and the point. a<3> rests on the plane face g<2> at the end of the lever L<2> while the point a<1> bears in a horizontal groove in a fixed member H. The plate thus receives two component rotations, one about the axis a<1>, a<2> proportional to the difference between the expansions of the rods E<1>, E' and the other about the vertical line through the point a<1>, proportional to the expansion of the rod E<1>, i.e. to the rise in temperature. The plate B carries, at right-angles to the plane of the points a<1>, a<2>, a<3>, an arm A on which is slidably mounted a pen P which is urged outwards by a spring R against a pin b. The board D on which the record is made is given a reciprocating movement to and from the pen so that a number of points are marked on the board through which a continuous line can be drawn. The board is carried by a member G which is mounted on runners 15, 16 on which it is reciprocated by a member U carried bv a lever which is operated by an expansible wire F through which an electric current is intermittently passed under the control of a make and-break device I.

Abstract: 900,662. Ventilating aircraft. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. May 2, 1961 [May 31, 1960], No. 19286/60. Class 137. [Also in Group XIII] In an aircraft cooling and/or pressurization system air, e.g. from a gas-turbine compressor, is delivered through a duct 12 to a pressureexchanger 11 which supplies high-pressure air and low-pressure air through ducts 14 and 13, respectively, the ducts being in heat-exchange relationship at 15, 16, and the cooled highpressure air passes to an expansion turbine 18 to be delivered to a further heat-exchanger 23, 24, where it cools the circulating fluid of an aircraft cabin and structure cooling system. The expansion turbine drives both the rotor of the pressure-exchanger and that of a motorgenerator 20 by means of shafts 19 and 21 and the two air streams are exhausted rearwardly to assist in the propulsion of the aircraft. The system may alternatively be used to pressurize an aircraft cabin (Fig. 3, not shown) or, as shown in Fig. 4, may combine the pressurization and cooling systems. In the latter modification two-way valves 43 and 49 are provided in the ducts 14 and 13 and have additional duct connections 40, 41 so that the valves may be set to supply air from a boundary layer region of the aircraft through the duct 41 to the pressure-exchanger which in this case acts as a pressure equalizer, the outlet stream from which is exhausted through the duct 40. Downstream of the valve 43 a by-pass duct 38 is connected to supply part of the high-pressure air through a heat-exchanger 39 and a control-valve 45 to an expansion turbine 46 which drives a generator 47 and supplies air for the cabin and structure cooling system as before. The remainder of the high-pressure air passes to a control valve 35 and is supplied to the aircraft cabin 36 either directly through the duct 34 or via the heat-exchanger 15, 16 and expansion turbine 18 as before. The generators 18 and 47 and the pressure-exchanger may be controlled by devices responsive to the speeds of the respective shafts.
