Title: Improvements relating to machines for grinding gear wheels
IPC: B23F5/04
Filed: 1934-10-26
Abstract: 443,305. Grinding gear - wheels. GEAR GRINDING CO., Ltd., and ORCUTT, A. H., Anne Road, Handsworth, Birmingham. Oct. 26, 1934, No. 30723. [Class 60] In a helical gear-wheel grinding-machine of the type in which two adjacent faces of the wheel teeth are ground simultaneously by a rotary grinding wheel while the workpiece is given a combined sliding and rotational movement, the grinding wheel can be displaced by fluidoperated means from the cutting position, in which its central plane is at an angle to the workpiece axis, to the trimming position in which its central plane passes through the workpiece axis. Fig. 1 shows a workpiece 7 mounted on a mandrel 8 supported by an indexing head stock 4 and a back-centre 5 on a slide 3 which is displaceable on a hollow bed 2 below an electrically-driven grinding- wheel c carried by a slide d. The slide d is movable vertically by the operation of a hand wheel s between guide surfaces x, y on a guide e depending from an arm f, Fig. 4, having a pivot spindle i rotatable in machine frame g. The wheel s may be operated through worm gearing by a hand wheel t to effect a fine adjustment of the slide d. The arm f carries a toothed quadrant k engaged by a rack l connecting two pistons m slidable in cylinders n. When the slide 3 is moved to the extreme right, a tappet 13 depresses a striker 14 and operates a piston valve 10, Fig. 5, in a cylinder 11 to admit fluid to one cylinder n and exhaust it from the other and thereby cause the arm f to move into engagement with a stop p on a segmental guide h. In this position the central plane of the grinding wheel passes through the axis of rotation of the head stock 4 and the grinding wheel may be trimmed by mechanism 6 mounted on the slide 3. When the slide 3 is moved to the left, the striker 14 is released and the piston valve 10 is moved by the spring 15 to reverse the fluid flow to and from the two cylinders n, thereby giving the grinding wheel the required inclination by causing the arm f to move into engagement with the stop o. The exhaust passage from the cylinder 11 is fitted with a spring-loaded valve retarding the fluid flow. When the inclination of the wheel teeth is opposite to that shown, the stop o is adjusted so as to determine the trimming position of the arm f and the stop p to determine the cutting position, while the fluid flow to the cylinders n is reversed by a valve 19 operated by a hand lever 26.

Title: Improvements in or relating to tape controlled telegraph transmitters
IPC: H04L13/06
Filed: 1954-10-28
Abstract: 761,951. Telegraph transmitters. CREED & CO., Ltd. (Lorenz Akt.-Ges., C.). Oct. 28, 1954, No. 31104/54. Addition to 761,497. Class 40 (3). In a tape-controlled transmitter as claimed in the parent Specification in which a lever operated by a magnet from a governor when the driving motor has attained a predetermined speed controls the transmission contacts and tape-feeding mechanism of the transmitter so that signal transmission is prevented until the motor is running at the operating speed, a manually-operated switch is provided in series with a switch operated by the governor so that the stepping of the tape can be arrested without switching-off the motor. In the circuit shown, the closure of a switch 1 connects the motor 2 to the mains and the closure of a switch 5 when the motor is running at the predetermined speed energizes the magnet 4 actuating a lever which opens short-circuiting transmission contacts and controls mechanism allowing the transmitter to feed the tape. The opening of switch 6, which is in series with the switch 5, de-energizes the magnet 4 so that the feed of the tape is suppressed. As shown in Fig. 2 a lever 9 is connected to a lever 18 carrying a pivoted pawl 20 arranged to rotate the sprocket 21. In the normal position the nose 11 of lever 9 engages a ledge on a slide member 10 so that the lever 9 is blocked against movement to actuate the tape-stepping mechanism. When the motor attains its predetermined speed magnet 4 is energized and the slide 10 is moved when the cam 8 has raised the nose 11 clear of the projection 14 so that the lever 9 is no longer blocked. If it is desired to suppress tape feed at any instant, the manual activation of switch member 22 rotates a frame 27 so that an arm 23 moved away from a stop 25 allows a spring member 26 to open contacts 6 in the circuit of the magnet 4 which, on release, and in conjunction with the raising of the nose 11 allows the slide 10 to move to the position shown in which the movement of the lever 9 is again blocked, and the tape-feed is suppressed.
