SPECIFICATION forming as or" was Patent No; 530,325, dated December 4, 1894. d
Application fild September it, 1894. Serial No. 523,108. (No model.)
To all whom it may concern:
a subject of theQueen of Great Britain and a resident of Brantford, Province of Ontario, Dominion of Canada, but temporarily residing at New York, in the countyand State-of New York, have made a new and useful In vention in Telephone-Switches, of which the following is a specification.
My invention is directed particularly to circuit to and through the receiver circuit,
and vice versa, and its object is to obtain certainty of operation in the switching apparatus under all conditions of operation.
My invention will be fully understood by referring to the accompanying drawings, in which- Figure 1 is a part diagrammatic, part elevational and part sectional viewof the circuits, circuit connections, bell, telephone receiver andswitching devices arranged in accordance with my improvement. Fig. 2 is a detail side elevational view of the mechanical switch actuating parts as seen looking at the body of the apparatus in Fig. 1 from the left toward the right hand side of the drawings, the receiver being broken away.-' Fig. 3 isa sectional view taken through Fig. 2 on the line 1-1, and as seen looking in the direction of the arrows upon that figure from right to left, the receiver, however, being removed and the switch in its upper position. Fig. 4 is a sectional view taken through Fig. 1 on the line 4-4, and as seen looking in the direction of the arrows upon-thatfigu're from right to left, and Fig. 5 is a similar sectional view taken through Fig. 1 on the line 5--5, and as seen looking in the same direction.
Referring now to the drawings in detail: A represents an ordinary telephone box; B, a well known form of trembler bell, and R a magneto receiver (preferably of the form shown) having attached to its backa sustaining extension lug or car Q.
D and D are binding posts which connect the receiver by conductors to w to the branch wires U2 and Q0 the former being connected to the line wire w which latter is normally connected through the bell B with a contact 1 spring .9 the conductor w being connected Be it known that I, ROMAINE G LLENDER,
to a similar contact spring 8 the line wirew being connected to a strong yielding switching spring 8' having a contacting projection 16 at its free end. The switching contact springs s, s and s are secured on the inside of the telephone box to an insulating block I by screws 71' t", '5 i 11 '6 See Figs. 3, 4 and 5. G is a sustaining bracket secured to a metal plate I by screws g g, said plate being in turn similarly secured to the telephone box A.
H is the switch lever which is pivoted at h to a block L secured by screws to the plate P, the outer end of said switch lever beingof curvilinear form as shown and adapted, when in the position shown in Fig. 1, to rest upon the inclined surface of the bracket G. The inner end of the switch lever H, whichis of metal,
is provided with beveled faces h and h upon p which the conducting lug or extensiont in of the switching lever H.
multaneously secured to the switch lever H so that their outer faces shall rest respectively under the contact springs s and s as the switch is thrown either up or down. See Fig. 4. t
The operation of my improved switchis a follows: Under the conditions shown in. Fig. 1, the receiver R is hanging upon the inclined bracket G and is held from sliding off said bracket by the curved'extension of the switch lever H. Consequently the line circuit is closed as follows: by conductor w, switch spring s contact point t, beveled or inclined face h, lever H, contact spring s conductor to, bell B, conductor w to line,so that any manipulation of the call generator 'at a distant station will ring the bell B. 'The subscriber, therefore, on receiving. a call removes the receiver R from the bracket G and in doing so causes the curved switch lever H to be lifted block 0 adapted to limit the upward throw I I are insulating blocks secured by screws to the metallic plate K which in turn is si- ICO until the contact point t sustained by the strong conducting spring 8" passes upon'the beveled or inclined face It, thereby causing the switch lever H to assume the position shown in Fig. 3, simultaneously breaking contact with the central switch spring .9 immediately after making contact between the switch lever and the remaining switch spring 8 The bell circuit is now ruptured and a new circuit is made as follows: from line 11;, by spring 8', contact point t, inclined or beveled face h, switch lever H, left hand switch spring 8 conductor 10 to binding post D conductor w through the receiver, conductor w binding post D, conductor w conductor to to line, the bell circuit having been' ruptured, as will be remembered, between the contact spring 8 and the switch lever H. After the subscriber has held the usual conversation, he returns the receiver to the bracket G and with the forefinger of the hand which conveys it to this point, presses down upon the switch lever H until, through the snapping action of the spring 3' and contact point t, it is caused to assume the position shown in Figs. 1, 4 and 5.
It will be observed that owing to the inclination of the bracket G the receiver R will not remain in position thereon unless the switch has been placed in the position shown in Figs. 1 and 5, making it therefore absolutely necessary that the subscriber shall return the switch tonormal position before his receiver will be held in place.
I am aware that numerous devices have been heretofore invented for causing a telephone receiver to effect the necessary circuit changes from the bell circuit to its own circuit, and vice versa, which devices are dependent in some instances upon the weight of the receiver, and in others upon certain manipulations to be effected by the subscriber, and I make no claim of such a generic nature as willinclude apparatus of this generic type. I believe it is new with me, however, to provide a permanent or rigid sustaining device for the receiver in combination with a switch,
which sustaining device fails to sustain the receiver unless the switchbe in proper position so that by their combined action the re- 5 o ceiver is held in place and the circuit closed through the call bell, and my claims are generic as to this feature.
Having thus described my invention,what I claim, and desire to secure by Letters Patent of the United States, is
1. A telephone sustaining device in the nature of an inclined bracket secured to a telephone box, in combination with a telephone receiver having a sustaining extension lug or car adapted to rest upon the inclined bracket and a switch leverprovided with circuit connections for shifting the circuit from the call bell to the receiver and vice versa and means for maintaining the telephone in suspended position upon the inclined bracket when the circuit is through the call bell.
2. A telephonic apparatus provided with a telephone sustaining device consisting of a permanent or rigid non-retaining support and a switch lever provided with means for retaining a telephone receiver upon said support through the united agency of the support and the retaining device, the arrangement being such that the receiver cannot be held by the support when the circuit is closed through it.
3. A sustaining device for a telephone re-' ceiver which fails to hold or sustain the receiver when it, the receiver, is being used, in combination with a switch and circuit connections to the call bell and receiver, said switch being provided with means acting conjointly with the support to hold or sustain the receiver only when the circuit is closed through the bell.
In testimony whereof I have hereunto subscribed my name this 13th day of September, 1894.
