ATTACHMENT FOR TELEPHONE-TRANSMITTERS.
Specification of Letters Patent.
Patented Oct. 24, 1905.
Application filed June 18, 1902. Serial No. 112,243. ('MocleL) 1'0 ctM w/wm it puny concern:
Be it known that 1, Louis S'r. J. JOHNSON, a citizen of the United States. and a resident of the city of Baltimore, in the State of Maryland, have invented a new and useful Attachment for Telephone-Transmitters, of which the following is a specification.
This invention appertains to attachments for telephone-transmitters, the object being to provide an indicating means which is applicable tothe casing of a telephone-transmitter, the construction thereof being such that it may be applied and detached without in any way defacing or altering the casing and when applied will not obscure the license-number of the transmitter.
This invention is designed primarily for use upon portable telephones, known as deskstands, and provides the mouthpiece-carrying frame of the transmitter-casing with a card, label carrier or support, which is held over the face-plate of a transmitter by means which engage the casing, so that the instructive, directive, or other matter on the card, label carrier or support will be in direct line of vision of the person using the transmitter. In practice the card or label will have printed or otherwise inscribed thereon directions for use or other matter, a space being left for the subscribers or exchange number, and the card, label carrier or support is shaped so as not to obscure the license-number of the instrument, the same being maintained parallel to the face-plate of the casing and surrounds the voice-opening and mouthpiece thereof. The indicating or directive card or label is protected by a transparent or diaphanous covering carried by the same support as the card or label, and the card or label carrier has marginal means for connecting the same to the casing rear of the mouthpiece-carrying frame.
The invention consists of an indicating attachment or label-carrier for transmitters and embodies in its construction a supporting member or carrier having an Opening which surrounds the voice-opening or mouthpiece of the transmitter and means for attaching the label carrier or support to the casing of the transmitter, as will be hereinafter set forth, and pointed out in the claims.
In the accompanying drawings, which illustrate several embodiments of my invention, Figures 1 and 2 are respectively front and side elevations showing the application of one form of the invention to atransmitter. Fig.
3 is a front elevation of the same construction as is shown in Figs. 1 and 2, the attachment being shown detached from the transmitter. Fig. 4 is a vertical section on the line 4: 4. Figs. 5, 7 and 9 are front elevations of modified forms of the invention, and
Figs. 6, 8, and 10 are vertical sections.
The transmitter is of the standard type, the mouthpiece'carrying frame being attached to a cup-shaped casing A by screws a a. The rear edge of the rim of the mouthpiece-carrying frame has a projecting edge or bead, and the aperture or voice-opening through the center of the face-plate of the diaphragm-casing is surrounded by a raised bead to afford a thicker support for the mouthpiece. The mouthpiece either frictionally engages the voice-opening through a face-plate of the transmitter or is screwed therein, either construction providing for the removal of the mouthpiece. The faceplate of each transmitter is provided below the mouthpiece with numbers, known as the license-number, the figures thereof being usually stamped into a metal plate which is securely attached to the face-plate. The license number being frequently referred to should not be obscured, and the plate a, in which the license-number is stamped, projects beyond the surface of the face-plate.
A metallic frame, support, or label-carrier B is constructed to present a rim which closely embraces the rim or edge of the mouthpiececarrying frame of the transmitter. The part B has an inward-extending flange 7), and when made as illustrated by Fig. 3 there are present bars o which maintain centrally with respect to the rim an annular frame, the inner margin 5 thereof being raised or struck up to extend slightly above the plane ofthe flange 7), and thus overlie the raised portion which surrounds the voice opening in the mouthpiece-supporting frame. The outer margin of this ring or annular frame is on the same plane as the flange l). The lower portion of the frame or member B presents a segmental part C, and through said part is an opening c, which corresponds as to shape with the license-number plate a, which is usually riveted to the face-plate of the transmitter below the voice-opening. The rim of the member B at its rear is bent slightly inward to engage and lie over the bead on the rear edge of the face-plate, and at points corresponding to the position of the screws ([6 a there are tongues or lugs b with openings therethrough, so that the screws which hold the parts of the casing together will hold the member or frame 13' thereon.
The frame or member B is preferably made up from a single piece, as shown, and while serving its purpose as a card-holder or labelcarrier does not in any way detract from the appearance of the instrument to which it is applied.
A card or label D is held in place by the part B, and such card has usually printed thereon the name of the company, instructions to the subscriber, or such subject-matter as may be desired, and on each card or label there is a space for the subscribers numher or other characters. The card D has preferably a straight lower edge which in use will rest upon the upper edge of the license-number plate a, and said card has also a central opening which is overlaid by the outer rim: of the annular frame which surrounds the mouthpiece. The outer perimeter of the card is covered by the flange b and the upper portion of the segmental part C of the frame B.
E refers to a cover of transparent or diaphanous material, as celluloid or collodion paper, and this may be shaped to correspond with the card used. In practice I prefer to have the card D and the protective covering of the same shape, so that they may be cut by the same dies.
In Figs. 5 and 6 of the drawings theframe or member B has a segmental portion 0 integral therewith, the same as in Fig. 3; but in this instance the central ring is separate from the frame and is held in place over the protective transparent covering by frictional engagement with the mouthpiece, this construction being used when the mouthpiece has a flange or is shaped so that it will overlie the inner raised portion of the ring which overlies the raised portion on the face-plate about the voice-opening to cover the inner edges of the card and covering.
In Figs. 7 and 8 I have shown a further modification in which an annular frame B is used, an annular card and transparent covering being used with such frame, also an inner detached ring. \Vith such a frame the rear edge may be provided with lugs 5 and the rim in addition to being turned or bent inward to overlie the bead on the rear edge of the face-plate may be slitted to give resiliency or allow for a greater expansion of the edge of the frame and for a variation as to the diameter of the bead on the rear edge of the face-plate of the transmitter. in the construction shown in Fig. 7 the card will have an opening to surround the license-number plate when it projects, or through which the number may be seen when stamped into the face-plate of the transmitter, and the covering may have a corresponding opening'or'not, according to the height of the license-number 1 plate or whether the numbers are impressed in the face-plate.
In Figs. 9 and 10 the frame or supporting member consists of a plate or cap with suitable connecting means for attaching to the casing of the transmitter. A central opening and a sight-opening c are formed in the plate. Above the opening through which passes the mouthpiece there may be slits, and between said slits the body portion may be depressed, such construction providing means for holding in place a slip or label which will carry particular information, as the subscribers or exchange number of the telephone. In Figs. 9 and 10 of the drawings the face or inwardprojecting portion of the frame is slitted, as shown at ffff, and the part between the slits is pressed slightly below the face of the frame to receive a slip or card which may be covered by a transparent substance, as mica or celluloid-paper. The general instructions or other data Whichit is desired to have on the plate may be printed or otherwise applied to the face of the plate 6*, which can then-be lacquered or varnished, the lacquer or varnish constituting in this instance theprotective covering for the printed matter.
The several forms of the invention herein described can be cheaply manufactured by stamping or spinning from sheet metal and by simply removing the mouthpiece of the transmitter can be quickly applied. The device does not mar the appearance of the transmitter or obscure the license-number thereof. Further, the subscribers number and other matteron the attachment is directly before the person using the transmitter.
The inturned rim of the label-carrier engaging the rear edge of the front part of the casing will hold the label-carrier in engagement with the face-plate of the diaphragmcasing, so-that it will not be disturbed when the screws are removed to have access to the interiorof the casing. Therefore theinturned rim is useful with the apertured lug.
