Title: Improvements in or relating to adjustable stands convertible into tables
IPC: A47B31/00
Filed: 1926-08-12
Abstract: 276,139. Louis, E. S., and Skippers, J. Aug. 12, 1926. Shelves.-In a stand of the kind which supports sleeves interconnected by parallel linkage so that they may occupy superimposed positions or an edge-to-edge position in which they constitute a table, as described for example in Specifications 1646/99, and 7536/00, [Class 3. Advertising &c.]. the supporting uprights of the stand are so coupled that they can be collapsed towards one another. As shown, the stand comprises legs or uprights 10 - - 13 of which the pairs 10, 11 and 12, 13 are connected by rigid bars 14, 15. The end pairs 10, 12 and 11, 13 are coupled by parallel pivoted bars 16, 17 so that they can be collapsed, and are held in service position by pairs of knuchle-jointed straps 18. Two leaves 20, 21, each corresponding in dimensions to the frame 10 - - 13, are interconnected by parallel pivoted links 22. 23 each pivoted midway of its length to the bars 17 by pivots 44 parallel to, or coincident with, the pivots 24 of the bars 17. By this arrangement, in the table position of the leaves, one half of each leaf lies over the stand. The leaves are preferably brought to the table position before the stand is collapsed. Means for locking the leaves in either of their two positions comprises two bolts 25, Fig. 4, arranged beneath the lower leaf and pressed by springs 26 to protrude beyond the ends of the leaf. In the superimposed position the bolts engage apertures in the legs 12, 13 and in the table position, Fig. 4, apertures 28 in the links 22. 23. The bolts are retracted by links 31, 32 and a hand-lever 29. Specification 276,140 also is referred to.

Title: Improvements in and relating to intercommunication telephone systems
IPC: H04M9/00
Filed: 1927-07-29
Abstract: 299,823. Davey, W. C. July 29, 1927. Intercommunication systems. -In a secret intercommunication system, the lifting of an instrument from its hook places it across common speaking lines and prevents any other station obtaining access thereto on its own initiative. In a modification, access tc the system by an unwanted subscriber is prevented only after the wanted subscriber has replied. The system shown in Fig. 1. comprises a. common pair of speaking lines 1, 2 a home or ringing line 6 for each station, and a common locking line 5 which, when a calling subscriber removes his instrument, short-circuits winding 13 of a relay at each other station. Energization of this relay is essential for the connection of an instrument across the lines 1. 2 and it is only operated (1) over winding 13 by removal of the instrument or (2) over winding 14 by ringing current. Station II is shown calling station III with station IV attempting to break in. Removal of instrument 7 completes a circuit (1, 15, lamp 16, 13, 10, 2) for the relay which at 17 connects the instrument across the lines and connects positive battery to wire 5 which is extended over contacts 12 of the other relays to that end of winding 13 which is normally connected through resistance 10 to negative. The ringing push 19 of station III at station II completes a circuit for bell 18 and winding 14 in series so that when the instrument at station III is removed it is placed across the lines. A station such as IV cannot ring if the speaking wires are engaged since the completion of the ringing circuit is only effected by energization of the relay at that station, but either of the engaged stations may call up a third station. The tail of the telephone hook engages one or other of two pins on the notched disc 21 so that when a receiver is replaced, the circuit of winding 13 is interrupted for a moment. The breaking of contact 15, alone, would not suffice since the relay would be held over this winding and the locking line. A relay common to the system may be used to apply positive potential to the locking line. The modified system shown in Fig. 2 comprises common speaking lines 22, 23, a common locking line 24, and a, home line for each station, separate ring- ing and speaking batteries 35, 25 being employed. Removal of instrument 29 from hook 30 completes a temporary circuit (33, 24, 26, 35, 23) for relay 32 which locks over 31 in series with 29 across the speaking lines. The ringing circuit over line 24 and a home line is completed by a push 34 and the wanted subscriber's instrument is placed across the lines in a similar manner to that of the calling subscriber. A common relay 28 in the speaking circuit, adjusted to respond to current through more than one station, now pulls up and at 26 breaks the ringing circuit and also initial circuit of relay 32 at unwanted stations.
