Title: Improvements in or relating to area measuring machines particularly intended for themeasurement of leather
IPC: G01B5/26
Filed: 1920-08-26
Abstract: 150,689. Krupp Akt.-Ges., F. Sept. 4, 1919, [Convention date]. Area meters.-In a machine particularly for the measurement of leather and of the type comprising a number of equidistant tracer wheels which can be raised to put into operation a corresponding number of measuring-wheels adapted to actuate, through bands or cords, the usual indicating- mechanism, the driving-roller B, Fig. 1, is positively connected to a shaft d<1> by means of a single arrangement of reversing-gear, Fig. 2, and the shaft a<1> is adapted to be coupled to a series of ratchet-wheels G<2> by means of friction clutchmembers d<3>, g<3>, connected to the shaft a<1> and ratchet-wheels G<2> respectively, when locking- pawls J holding the ratchet-wheels are released. The reversing-gear comprises a wheel b<1> fixed on the shaft of the roller B, wheels C, c<1>, c<3> fixed on a rotatable shaft c<2>, and wheels D, E loose on the shaft d<1> ; the wheels b<1>, C and c<1>, D interengage directly, but the wheel c<3> is connected bv a sprocket chain c<4> with the wheel E and a clutch F, slidable along but rotatable with the shaft d<1>, enables this shaft to be rotated in either direction. During a measuring-operation, the shaft d<1> is driven in the direction of the arrow x, the material is placed on a table A<2> and is led beneath guide-plates N provided with prongs n' and secured to arms M<1> carrying pressure rollers m<3> whereby it is flattened out and pressed down on to the roller B. The material is carried forward between the roller B and tracer wheels or rollers k<3>, that, being lifted thereby, rock the bellcrank levers K on which they are mounted and by means of set-screws k<2> force the pawls J out of engagement with the teeth of the ratchetwheels G<2>, which are thereupon rotated by the shaft d' bv means of the friction clutch members d<3>, g<3>, themselves pressed together under the action of a plate-spring H. To the ratchet-wheels G<2> are rigidly secured disks G, every two of which are connected to a band g' adapted to operate the indicating-device and provided with a weight to exert a pull in the direction of the arrow y. Prongs a<3> occupying grooves b<2> on the roller B conduct the material to a receiving-table A<4>. When a tracer roller k<3> is no longer engaged by the material it returns to normal position by the action of the spring i<1> of the pawl J, which at the same time arrests the ratchet-wheel G<2>. In the normal position of the parts, a pin g<4> on each ratchet-wheel engages a stop a<1> mounted on the frame A and to restore the parts to this position the clutch F bv means of a lever f<1> is moved to couple the wheel E to the shaft a<1> so as to reverse its direction of rotation.

Title: Improvements in or relating to micrometer screw gauges
IPC: G01B3/18
Filed: 1933-09-12
Abstract: 408,512. Linear - dimension gauges. AMBROSE, SHARDLOW, & CO., Ltd., Washford Road, Attercliffe, and ORR, H., 37, Huntley Road, both in Sheffield. Sept. 12, 1933, No. 25273. [Class 106 (ii).] The sleeve or thimble of a micrometer screw gauge is provided with a number of concentric circumferentially arranged columns of numbers for co-operating with the scale on the barrel and representing a numerical enlargement of the divisions of the scale. The movable anvil 6 is screw-threaded and moved by a sleeve 7 which traverses the barrel 5 on which is the usual major scale 8 divided so that with a screw of forty threads to the inch each division represents 0.1 inches. Each division is subdivided into four so that each subdivision is equal to .025 inches, or 25 thousandths of an inch. The sleeve has the usual bevelled edge and is divided circumferentially into 25 divisions. It is also provided with four columns of numbers arranged in line with the graduations on the sleeve. Since each graduation around the edge represents one thousandth of an inch the columns are numbered 00 to 24 ; 25 to 49; 50 to 74 ; and 75 to 99. Fig. 2 shows in development the position of the sleeve relatively to the main scale 8 for five positions A to E. To take for instance the position B, the edge 9 is somewhere in the third division between .6 and .7. In the third column of figures the reading is 63. The dimension therefore is .663.

Abstract: 1,018,669. Punching; stamping-out. L. RADO and M. ROBERT. June 25, 1963 [June 25, 1962], No. 25313/63. Heading B4B. A punching-apparatus for perforating or stamping-out a continuously-moving strip 28 includes a knife-edge 29a and a co-operating hammer 27, and means to supply compressed air on the hammer side and to that part of the strip to be removed when the knife and hammer are brought together. As described, compressed air is applied to a nozzle 2 normally closed by a valve 3 actuated by a striker 8 and a spring 9. A cam 14 periodically actuates a pusher 11 and compresses the spring, so that when the pusher is disengaged from the cam the spring expands and the head of the striker 8 opens the valve momentarily, the valve being closed again by the compressed air when the spring has expanded. The time the valve is open may be adjusted by a cap 10 which varies the expansion of the spring. When the valve is open compressed air enters a bore 15 and actuates a piston 16 against a spring 22, to force the hammer 27 which is secured to the piston by a ball-and-socket joint against the knife-edge 29a of a punching tool 29 and perforate the strip 28. The waste " pip " is forced by the compressed air in a bore 30 in the hammer into the canal 31 in the centre of the tool support 32. The valve-support 1 and the tool-support 32 may be clamped in adjusted positions by bolts 19, 19a. In a further embodiment, cutting is effected on one edge of the ribbon by providing the punching-tool 29c, Fig. 7 (not shown), with a recess 35 in which is slidably mounted a protruding boss on the hammer, so that compressed air cannot escape through the bore 30 before cutting takes place.

Sept. 7, 1934, No. 25793. [Class 106 (ii)] [See also Group XXVI] In order to determine the power developed within the cylinder of a reciprocating engine, the average temperature or pressure reading at an instant just prior to the exhaust release is taken. In the apparatus shown in Fig. 7, which is suitable for a two-stroke engine, the gases flow from the combustion chamber into a chamber 27 by a duct 28. The temperature is read by means of a pyrometer 29. In Fig. 8, the gases pass a ball check 32 into a pressure averaging-chamber 33. The pressure is indicated on a gauge 34. The gauge 34 may be calibrated in terms of work. A construction is described wherein the conduit leads to a nozzle which discharges into a Venturi which discharges into a chamber open to the atmosphere. A supplementary chamber is connected by a small port to the entrance of the Venturi which creates a negative pressure therein as indicated by a manometer. In another construction a number of cylinders are each provided with a determining-device connected byleads to a selector device associated with a reading-instrument. A double-acting four-stroke cycle engine with two gauging ports controlled by cam-operated lift valves, is also described.
