Title: Method of and apparatus for cutting shapes from cloth and other suitable fabrics
IPC: D06H7/24
Filed: 1961-05-13
Abstract: 936,864. Cutting apparatus. C. TUSHTNGHAM. Aug. 10, 1962 [May 13, 1961], No. 17520/61. Class 31(1). Apparatus for cutting shapes from cloth comprises a cutting head provided with a multiplicity of aligned but contiguous cutters, any or all of which are adapted to be actuated at predetermined intervals according to a predetermined pattern and with respect to a relatively moving length of cloth. As shown, the cutting head has mounted therein a row of aligned cutters 4 which are retained in a retracted state, e.g. by means of springs and are individually depressed by means of jacks 5 coacting with pneumatically-operable pistons 6 within cylinders 7 ; alternatively, the punches may be actuated by cams or push rods. The operation of the cutters is controlled by a pattern through the medium of punched cards, magnetic tape or jacquard mechanism. Alternatively, the cutters may be operated by means of a rotary cylinder mounted in proximity to the jacks and provided with projections corresponding to the pattern of cut desired. The cutting head is mounted upon a work-table 10 provided with a track on which the head can be longitudinally traversed back and forth. For this purpose, the head may incorporate a driven pinion or pinions coacting with a toothed rack or racks on the table or the table may include a driven lead screw or screws coacting with nut or like mechanism associated with the head. Cloth 1 to be cut is fed from a roll and passed over guide rollers 2, 3 and beneath the cutters. The free end of the cloth may be held in contact with the table. When the head is operated it moves longitudinally along the table andecloth is automatically fed and laid on the table at a predetermined speed, during which traverse the required cutters are depressed. If desired, the cloth may have an intermittent feed imparted thereto, synchronized with the operation of the cutters. The cutting head may be stationary relative to the table and the cloth traversed along the table at a predetermined speed. Two or more rows of cutters may be associated with the cutting head. The pattern may take the form of a tracing which is scanned by the apparatus by photo-electric means coacting with electric relays coupled to the cutters. Automatic sharpening devices are provided for the cutting edges of the cutters. Pneumatic or other means may be employed for removing the cut cloth and the waste and for extracting dust or fly.

Filed: 1950-07-13
Abstract: 1,090,131. Starting; valve gear; treating charges. H. R. RICARDO and J. F. ALCOCK. March 8, 1951, No. 17559/50. Headings F1B and F1K. In an internal combustion engine a liquid oxygen releasing compound e. g. hydrogen peroxide, is fed into the cylinder which is also supplied by fuel such as herocene which has been vaporized by burning a part of the fuel with oxygen from a part of the oxygen releasing compound which has been catalytically decomposed. On opening the valve H 1 , compressed air from the tank H forces fuel from the container G through the nozzles G 1 , and hydrogen peroxide into the pump E<SP>1</SP>, and a metered part through the nozzle F 2  into a chamber K where it is decomposed by a catalyst e.g. silver, J 1 . Part of the fuel is burnt with the oxygen thus released, the mixture being ignited by the pressure operated device L. The heat engendered by the partial burning vaporizes the remainder of the fuel which passes into the cylinder A. In the first stages the tappet D 1  is on the cam D 3 , the engine operating as a uniflow compressed fluid engine. As the speed increases the catch D 9  is tripped by the device D 11 , the spring D 10  moves the control rod D 8  which causes the tappet D 1  to operate from the cam D 4 , and also causes the injector E 1  to pass hydrogen peroxide to the cylinder A.

Title: Improvements relating to braces for personal wear, belts, bands or the like
IPC: A41F3/00
Filed: 1930-06-07
Abstract: 351,223. Straps and bands for personal wear. MARTIN, P. A., New Works, Granville Street, Birmingham. June 7, 1930, Nos. 17698 and 29708. [Classes 43 and 141.] Relates to braces, belts, garters, and like bands for personal wear of the kind that comprise one or more spring bands formed from wire bent from side to side with loop coils at the bends ; and consists in attaching tab-ends, buckles, or other fittings to the bands by providing the fittings with folded-over, loop, or hook parts the closed ends of which have oppositely-directed edge portions engaged laterally between longitudinallyadjacent coils of the band. As shown in Figs. 2 and 7, a belt comprises two spring bands 11, 12 secured side by side by lacing 14, 15. A buckle 2 is secured to the bands by a leather tab 1 that has side recesses 26 between which is a hole 19. The tab is folded across the recesses, the ends of the bands 11, 12 are separated laterally, before the lacing 14 is completed, and the fold of the tab is inserted between adjacent inner coils 13 of the bands. The corl 14 is then passed through the hole 19, the lacing is completed as shown, and the ends of the band are additionally secured by a metal clip 17. Finally, the folded end 20 of the tab is stitched to the body of the tab as at 22. A tab 18 for co-operation with the buckle 2, and ring fittings 4, are secured similarly to the spring bands. In a modification, Fig. 10, the tab I has slots 29 in place of the side recesses. When the end 32 of the tab is folded over, a loop 30 is formed which, as before, is inserted between inner coils of the bands, aid also outer loops 31, which are engaged between outer coils of the bands. In other modifications, the tab 1 has one or more holes through which bhe spring bands are threaded before the tab is folded over. Figs. 23-26, not shown, show the application of the invention to braces having spring shoulder straps and leather tab-ends. Metal clasp fittings 50, 52, Fig. 27, are secured to the spring bands 11, 12 of a belt by means of metal plates 54 formed with hooks 57 that are engaged between outer coils 13 of the bands. The hooks may be replaced by loops or sleeves. In a modification of this arrangement, Fig. 35, sleeves 64 are mounted on the clasp fitting 50 for limited lateral tilting movement. After the sleeves have been tilted, the spring bands 11, 12 are engaged with the sleeves, the latter are returned to parallelism, and a locking sleeve 67 is pushed over them.
