- FIG. I is an exploded perspective view of the subset showing the upper shell and the handset, the center plate with the components mounted thereon, and the lower shell.
- FIG. 2 is a perspective view showing the rear of the subset and the recesses formed to accommodate the handset.
- FIG. 3 is a cross section taken along line 3-3 of FIG.
- FIG. 4 is a perspective view of a U-shaped leg of the center plate.
- FIG. 5 is a cross section showing the mounting means for the lamp under the push-button.
- FIG. 6 is a top view of the center plate with the slanted bracket 15, FIG. I, removed, showing the mounting of the components on the center plate.
- the plate 3 is composed of two identical flanged plates positioned back to back.
- the flanged portions serve as retaining walls for the lower edge of shell 1 as well as for the upper edge of shell 2.
- Shells 1 and 2 are preferably made of vacuum molded plastic material.
- the upper shell 1 has a flattened front portion with a forward downward slant, upon which is mounted plate 4. This plate is attached to bracket 15 which is in turn mounted on center plate 3. Plate 4 thus serves as an escutcheon plate for the components mounted on bracket 15 to be considered later.
- the lower shell 2 is generally dish-shaped and has a generally flat bottom portion serving as a base for the subset.
- the rear edge of shell 2 is slightly higher than the front edge, thus with the subset assembled, the plate 4 is tipped forward slightly to further enhance the accessibility of the components mounted thereon by the user.
- Brackets 13 and 14 as shown in FIG. 3, extend from the lower surface of plate 3 and serve as mounting brackets to which lower shell 2 is fastened.
- Brackets 13 and 14 are generally U-shaped, for example, see bracket 13 as shown in FIG. 4, where it is observed that its center portion 27 has holes therein for attaching the lower shell 2 to the center structure by means of screws 33, the upper portions 28 ofbracket 13 being attached to the center plate 3. In this way, the uper edge of shell 2 may be tightly abutted against the lower surface of plate 3 when screws 33 are tightened.
- brackets 13 and 14 when shells 1 and 2 are removed from plate 3, such as for inspection or maintenance of the telephone, brackets 13 and 14 then serve as legs to support plate 3, for example on a work bench.
- Shell 1 is similarly abutted against the upper surface of plate 3 by means of screws 43 which fasten to bracket 15.
- the components of the subset which may be generally as described in the aforementioned patent application by R. T. Cleary, are mounted on both sides of center plate 3, as shown in FIGS. 1, 3, and 6.
- transmission network 25 is held within an aperture in plate 3 by the two mounting brackets 37 which are fastened to network 25 and to the upper surface of plate 3; flasher assembly 36 is similarly held in an aperture in plate 3 by bracket 39 which is fastened to the lower surface of plate 3; induction coil assembly 30 and capacitor 40 are held to the upper surface of plate 3 by brackets 42 and 44 respectively.
- Hookswitch spring pile up 23 and transformer assembly 41 are likewise attached to the lower surface of center plate 3 by mounting brackets.
- slanted bracket 15, which is fastened to the upper surface of center plate 3 mounts several components, namely, dial 24 with finger wheel 5, volume control 7, push-button 6 and microphone 8.
- the hookswitch bars 11 protrude slightly above the floor of recessed portions 10. Arm 21, to which but 11 is attached, pivots about pin 22 which is in front of the recessed portions 10. It is noted that the floor of recessed portions 10 has slots through which actuating bars 11 extend. This floor is slanted downwardly from Front to rear with respect to the horizontal. An advantag of this construction is that the handset is guided into the closed end of the recessed portions 10. The top edge of bars 11 are slanted in the same direction as the fioor of recessed portions 10, but at an angle of slant which is slightly greater.
- Nise patent discloses a somewhat similar hookswitch mechanism, however th pivot point of bookswitch bars 11 is behind the recessed portions 10, and the tloor of the recessed portions 10 has no slant from front to rear.
- Push-button 6 is a rocker-type on-otl switch for use on a loudspeaking telephone; it is mounted on plate 15 and serves as a housing for tubing 16. Both push-button 6 and tubing 16 are of translucent material such that when lamp 17 is lighted the push-button is illuminated from underneath. Tubing 16 is mounted in slots 18 and 19 in plate 29 which is attached to plate 15. Slots l8 and 19 are slightly smaller in diameter than tithing 16 such that when the ends of tubing 16 are threaded therein, they are held tightly to plate 29 without further attachment. It is noted that tubing 16 forms a U-shape, with lamp 17 positioned in the center portion of the U, and the lamp connecting wires 20 extend from one leg of the U. Lamp 17 is shown mounted under th on" side of the on-off rocker-button, and is electrically connected such that it lights when the on" side is pushed, and extinguishes when the ofl' side is pushed.
- the loudspcaking telephone is thus seen to be constructed of three basic parts; the upper and lower shells, and the center mounting plate. Because of this type of construction. the center plate can be assembled in several stages with the components mounted in the described manner in a space-saving fashion, while the legs serve to hold the plate in a convenient position. Then, as the last step in assembly, the upper and lower shells and escuteheon plate are added, completing the subset.

13 Claims. (Cl. 179--100) Matter enclosed in heavy brackets appears in the original patent but forms no part of this reissue specification; matter printed in italics indicates the additions made by reissue.
This invention relates to telephone equipment, and more particularly, to a new and novel construction of a telephone substation instrument.
In the development of the telephone field, telephone subset construction has been relatively neglected. There have been many innovations to provide a more versatile and functional subset, and only recently have there arisen significant changes in the outward appearance of the sub set. However, there has been no major change in the fundamental construction of the subset, that is, a change from the conventional construction which features a base on which are mounted the components and to which the subset housing is attached.
It is a particular object of this present invention therefore, to provide a telephone subset which employs a unique and improved mounting arrangement.
A further object is the provision of a telephone subsetwhich lends itself well to rapid assembly and maintenance.
A feature of this invention is the provision of a tele phone subset having a housing made up of two shells fast ened to a center divider plate.
A further feature of this invention is the provision of a telephone subset having a center divider plate both sides of which serve as a mounting surface for the components.
A further feature of this invention is the provision of a telephone subset having a center divider plate which has legs serving as a support for the center plate during assembly and maintenance.
A further feature of this invention is the provision of a telephone subset having hookswitch actuating bars of the general type disclosed and claimed in patent application Serial No. 21,454, now US. Patent 2,990,456 issued to W. C. Nise, except that the hookswitch actuating bars are pivoted in front of the handset wells, and the top edge of the actuating bars are slanted from the horizontal such that the rear edge is higher than the front edge.
A further feature of this invention is the provision of a telephone subset having a lamp mounted under a push button by means of a section of translucent plastic tubing.
Briefly, the embodiment of the invention described herein relates to a loudspeaking telephone subset having a housing made of an upper shell and a lower shell, both fastened to a center plate. The center plate has legs which serve to support the plate when it is removed from the two shells. A typical circuit for the loudspeaking telephone subset shown herein has been disclosed in co-pending patent application Serial No. 844,393, filed October 5, 1959, by R. T. Cleary.
The invention will be more fully understood from the following detailed description of an embodiment thereof. In the accompanying drawings:
FIG. I is an exploded perspective view of the subset showing the upper shell and the handset, the center plate with the components mounted thereon, and the lower shell.
FIG. 2 is a perspective view showing the rear of the subset and the recesses formed to accommodate the handset.
FIG. 3 is a cross section taken along line 3-3 of FIG.
Reissuecl June 14, 1966 2 showing, among other parts, the legs which support the plate when it is removed from the shells, and the hookswitch arm and its pivot arrangement.
FIG. 4 is a perspective view of a U-shaped leg of the center plate.
FIG. 5 is a cross section showing the mounting means for the lamp under the push-button.
FIG. 6 is a top view of the center plate with the slanted bracket 15, FIG. I, removed, showing the mounting of the components on the center plate.
Referring now to the drawings it may be noted that in H65. 1 and 3, the upper shell 1, center plate 3, and lower shell 2 of the loudspeaking telephone subset are shown in non-assembled and assembled condition respectively. The plate 3 is composed of two identical flanged plates positioned back to back. The flanged portions serve as retaining walls for the lower edge of shell 1 as well as for the upper edge of shell 2.
The components of the subset, which may be generally as described in the aforementioned patent application by R. T. Cleary, are mounted on both sides of center plate 3, as shown in FIGS. 1, 3, and 6. For example, transmission network 25 is held within an aperture in plate 3 by the two mounting brackets 37 which are fastened to network 25 and to the upper surface of plate 3; flasher assembly 36 is similarly held in an aperture in plate 3 by bracket 39 which is fastened to the lower surface of plate 3; induction coil assembly 30 and capacitor 40 are held to the upper surface of plate 3 by brackets 42 and 44 respectively. Hookswitch spring pile up 23 and transformer assembly 41 are likewise attached to the lower surface of center plate 3 by mounting brackets. In addition, slanted bracket 15, which is fastened to the upper surface of center plate 3 mounts several components, namely, dial 24 with finger wheel 5, volume control 7, push-button 6 and microphone 8.
The hookswitch bars 11 as viewed in FIGS. 2 and 3, protrude slightly above the floor of recessed portions 10. Arm 21, to which but 11 is attached, pivots about pin 22 which is in front of the recessed portions 10. It is noted that the floor of recessed portions 10 has slots through which actuating bars 11 extend. This floor is slanted downwardly from Front to rear with respect to the horizontal. An advantag of this construction is that the handset is guided into the closed end of the recessed portions 10. The top edge of bars 11 are slanted in the same direction as the fioor of recessed portions 10, but at an angle of slant which is slightly greater. The previously mentioned Nise patent discloses a somewhat similar hookswitch mechanism, however th pivot point of bookswitch bars 11 is behind the recessed portions 10, and the tloor of the recessed portions 10 has no slant from front to rear.
Push-button 6, as viewed in FIG. 5, is a rocker-type on-otl switch for use on a loudspeaking telephone; it is mounted on plate 15 and serves as a housing for tubing 16. Both push-button 6 and tubing 16 are of translucent material such that when lamp 17 is lighted the push-button is illuminated from underneath. Tubing 16 is mounted in slots 18 and 19 in plate 29 which is attached to plate 15. Slots l8 and 19 are slightly smaller in diameter than tithing 16 such that when the ends of tubing 16 are threaded therein, they are held tightly to plate 29 without further attachment. It is noted that tubing 16 forms a U-shape, with lamp 17 positioned in the center portion of the U, and the lamp connecting wires 20 extend from one leg of the U. Lamp 17 is shown mounted under th on" side of the on-off rocker-button, and is electrically connected such that it lights when the on" side is pushed, and extinguishes when the ofl' side is pushed.
The loudspcaking telephone is thus seen to be constructed of three basic parts; the upper and lower shells, and the center mounting plate. Because of this type of construction. the center plate can be assembled in several stages with the components mounted in the described manner in a space-saving fashion, while the legs serve to hold the plate in a convenient position. Then, as the last step in assembly, the upper and lower shells and escuteheon plate are added, completing the subset.
