IPC: D05B3/02
Filed: 1924-10-07
Abstract: 228,085. Fairweather, W., (Singer Manufacturing Co.). Oct. 7, 1924. Multiple - needle machines; needle - driving mechanism, disconnecting; needle holders.-In a two-needle sewing-machine in which one needlebar can be thrown out of action, for example when turning a corner in the seam, the disengaged needle-bar is automatically brought into operation again at the end of a predetermined interval. The needle-bar 9 is continuously reciprocated by a crank and pitman 5 and is grooved, Fig. 7, to receive the disconnectable needle-bar 11, which at its upper end carries a yoke 20 and connecting bolt' 21. The eyed end of the bolt slides upon a rod 25 fixed on a slide 26 which can be moved endwise by a lever and pitman 35. When the bolt 21 is withdrawn shoulders 90, Fig. 8, on the needle-bar 9 carry the needle-bar 11 to its highest position and it is retained there by a spring stop 91. A spring buffer 95 prevents the needle-bar 11 from being carried up further by subsequent friction with the needle-bar 9. The needle-holder 18 on the bar 11 is formed with a ring 17 which embraces the bar 9 and the needleholder 14 of the bar 9 has a half ring piece 13. The pitman 35 by which the bolt 21 is actuated is pivoted to a swinging frame 37, Figs. 1 and 3, which is turned against the pull of a spring 76 by a treadle-operated lever 74, 75 when the needle-bar 11 is being disengaged. This movement of the frame carries a ratchet-wheel 47, pivoted on the frame, into engagement with a pawl 78 continuously reciprocated by an eccentricrod 83 and at the same time a latch 66 slips over a pin 73 on the frame to lock it. Thereafter the ratchet-wheel is turned until a lateral lug 61 on the wheel engages a part of the latch 66 and disengages the latch from the pin 61 so that the frame 37 can be drawn back by the spring 76 and by means of the pitman 35, the coupling bolt 21 moved to recouple the needle-bars. The ratchetwheel, when it is carried by the movement of the frame out of engagement with the pawl 78, is returned by a spring until a shoulder engages the underside of a stop 57. The lug 61 is formed on a plate 48 adjustably clamped on the side of the ratchet-wheel and an index 62 on the plate moves over a scale on the wheel which indicates the positions corresponding to the several numbers of stitches during which the needle-bar 11 may be kept out of action.

Abstract: 532,140. Toasting-apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 17, 1939, No. 23750. Convention date, Aug. 17, 1938. [Class 28 (i)] The invention relates to electric toasters of the type in which a slidably-mounted slice holder is moved to the toasting position by hand, and to the non-toasting position by a spring when released by a clockwork timing mechanism, and comprises improvements in the time-controlled operating mechanism, and in means for non- rotatably guiding a carriage supporting the slice-holder and for cushioning its movement by a pneumatic dashpot A pair of heating chambers 10, Fig. 1, are each provided with a pair of heating elements 14, and are surrounded by an outer casing 18 provided in the top wall with a pair of elongated openings for the insertion of bread slices. Mounted in each heating chamber 10 is a slice holder or tray 19, which projects through vertical slots in the front wall 13 of the heating chamber for attachment to a supporting carriage 20, the rear end of the tray 19 being formed with an extension 29a engaging a vertical slot in the rear wall 11. The carriage 20 is slidable on a vertical rod 24, and is lowered to the toasting position by means of a handle 30, which is connected by a tongue 30a to a plate-like bracket 32 mounted on the front of the carriage 20. On the lower end of the bracket 32 is an offset lug 37 adapted to engage an elongated pivoted latch 38, so as to hold the carriage 20 and tray 19 in the lower or toasting position, against the action of a tension spring 39 arranged to raise the carriage. The latch 38 is urged to its locking position by a spring 38a, and is provided on its upper end with an abutment 42, Fig. 4, engaging a cam 41 pivoted to a fixed bracket 43 and adapted to release the latch at the end of a time interval determined by clockwork. The clockwork comprises a spring-winding shaft 45 with pinion 46 meshing with a rack 47, which is moved downwards (to wind the spring) by the carriage 20 through the engagement of a pivoted pawl thereon with an abutment 48 on the rack, the pawl being released from the rack by a spring abutment at the end of the downward movement, a switch for the beating elements being also closed. At the end of a predetermined time (adjustable by a control knob 67, Fig. 1), the abutment 48 on the rack strikes the underside of the pivoted pawl 41, which thus turns the latch 38 in a clockwise direction to release it from the lug 37, allowing the carriage 20 to rise to the non-toasting position. The bracket 32 is capable of a limited pivotal movement about a tongue-and-slot connection 33 with a carriage 20, whereby the carriage may be released from the latch 38 by manipulation of the handle 30. The carriage 20 is provided with a pneumatic dashpot surrounding the guide rod 24, whereby its upward movement is cushioned.

Abstract: 1,221,738. Propynyl phosphonic acid and salts thereof. MERCK & CO. Inc. 12 May, 1969 [15 May, 1968], No. 23964/69. Heading C2C. A salt of 1-propynyl phosphonic acid is prepared by treating a mono- or diester of the formula or mixture thereof with a base, R being a straight or branched chain alkenyl or alkynyl group having 2 to 7 carbon atoms or a substituted or unsubstituted monocyclic aryl group and R<SP>1</SP> is hydrogen or is a group as defined for R. Preferably R and R<SP>1</SP> are 2-propynyl groups. The treatment is usually effected by contacting the ester in a solvent with the base for sufficient time to cleave the ester. The base used may be a strong inorganic or organic base, e.g. an alkali or alkaline earth metal oxide or hydroxide, a basic quaternary ammonium type anion exchange resin, triethylamine, trimethylamine, triethanolamine, an N-alkylpiperidine or tetramethyl ammonium hydroxide. The salts may be converted to the free 1-propynyl phosphonic acid by treating with a mineral acid, e.g. HCl or H 2 SO 4 . Suitable solvents for the main reaction include water, alcohols, dimethylsulphoxide, N,N<SP>1</SP>-dimethyl formamide and sulpholane or an excess of the base (when appropriate) may be used as solvent. The sodium salt of 1-propynyl phosphonic acid may be converted to the sodium salt of cispropenyl phosphonic acid by hydrogenation and the cis-propenylp hosphonicac id may be oxidized with H 2 O 2  to form racemic cis-1,2-epoxypropyl phosphonic acid which may be recovered as the sodium salt and the latter treated with quinine in methanol to yield the quinine salt of (-) (cis- 1,2-epoxypropyl) phosphonic acid which is then converted to the ammonium salt by treating with NH 4 OH in water, details being given for each step of the process. The (-) (cis- 1,2-epoxypropyl) phosphonic acid is an antimicrobial agent and may be administered orally e.g. in the form of its Na, K or Ca salt, or parenterally. Also, salts of (+) (cis-1,2-epoxypropyl) phosphonic acid inhibit undesirable bacterial growth in the white water used in paper mills, or in paints e.g. polyvinyl acetate latex paint.
