Title: An Improvement in Grinding Machines
Inventor: GUEST JAMES JOHN
Filed: 1906-01-12
Granted: 1907-01-12
Abstract: 850. Guest, J. J. Jan. 12. Surfacing.-In grinding-machines in which the work is supported between a headstock and a tailstock adjustable along a table, the table is protected from spent abrading-material and liquid by a system of telescopic guards. One guard E is attached to the headstock B, another guard F is attached to the tailstock C, and a third guard D with a joggle in the centre is fixed to the table A. The headstock and tailstock are undercut or slotted to allow the guard attached to the opposite piece to pass them. In machines with short tables, the two guards attached to the headstock and tailstock may be made the length of the table, as described in Specification No. 15,854, A.D. 1900, and the two pieces will be sufficient. The present invention is particularly applicable to longer machines, the guards E, F being made to stretch only just over half the extreme distance between the headstock and tailstock and not projecting beyond the ends of the guideways when the headstock and tailstock are brought together. If desired, additional guard pieces may be used and additional removable joggled pieces D may be fastened to the table.

Patent GB-190706280-A (GB)
Title: Improvements in Electric Telegraphy.
Inventor: KITSEE ISIDOR
Filed: 1907-03-15
Granted: 1907-12-12
Abstract: 6280. Kitsee, I. March 15. Telegraphs.-Relates to receiving-apparatus for line or cable telegraphy in which signals are transmitted by alternate positive and negative impulses of the same duration and intensity, dot-and-dash signals being determined by the time intervals between successive impulses. The receiving-apparatus comprises an electro-magnetic commutator switch, which reverses the connexion of the receiving instrument or relay with respect to the line as each impulse is received, so that the line impulses always pass through the relay in the same direction. The commutator comprises ring portions 18, 21 having projections extending toward each other, and also short contacts 19, 20, which are cross-connected to the projections of the ring portions as shown at 35 so that the brushes 3, 4 connected to the relay 7 are alternately brought into connexion with the rings 18, 21 and therefore with the brushes 2, 5 connected to the line-wires 1, 36. The contact-tongue 9 of the relay 7 normally rests against the stop 10, thus completing a circuit through the small resistance 13, shunting the magnet 15, which rotates the commutator switch by ratchet-mechanism. The Morse sounder or other instrument 32 is in circuit with the two springs 25, 26 bearing on an extension of the commutator switch. In the normal position of the apparatus, the magnet 15 is shunted by the resistance 13, and the spring 26 rests on an insulating-part 24. On the receipt of the first current impulse, the relay 7 opens the contact 9, 10, energizing the magnet 15 and moving the commutator one step, thus reversing the connexions of the relay for the next impulse, and at the same time bringing the brush 26 upon a conducting-part 23 so as to complete the circuit of the sounder 32. This circuit remains closed until the next current impulse of reverse polarity causes the relay 7 again to open the contact 9, 10, thereby energizing the magnet 15 and moving the commutator a-second step to break the circuit through the sounder 32 and again reverse the relay connexions with respect to the line.
