Specification of Letters Patent.
Patented Oct. 28, 1919.
Application filed October 20, 1916. Serial No. 126,744. Renewed March 19. 1919; Serial No. 283.666.
especially designed and cooperatively so arranged, whereby the messages are received very distinctly by the operator and without harshness to the ear and in which are included improved devices adapted for being readily adjusted by the operator for reducingthe audibility of the sound and to shift the sounder or receiver from operating as a loud, to a low or secret sounder, particularly in offices wherea large number of clickers are being used.
With other objects in view that will hereinafter appear, our invention is an improved telegraph instrument thatembodies the peculiar features of construction and novel arrangement of the parts hereinafter fully described specifically pointed out in the appended claims and illustrated in the accompanying drawing, in which:
Figure 1 is a perspective view of our improved telegraph instrument, the same being shown as applied for use.
Fig. 2 is a top plan View thereof with the top or cap member and the supplemental or diaphragm sound reproducing elements omitted.
Fig. '3 is a longitudinal section taken on the line 3-3 on Fig. 1 with the cap and the diaphragm shown in anoperative position.
Fig. 4. is a cross section on the line l4 on Fig. 2.
Fig. 5 is a perspective view of the sound ing bar.
Fig. 6 is a similar view of the base iron or plate with the magnets and the sounding anvil mounted thereon.
Fig. 7 is an inverted plan view of our improved telegraph instrument, and Fig. 8 is r which preferably is an ordinary telephone receiver of the head type with a head band A to hold'the instrument to the ear, as is clearly shown in Fig. 1, which illustrates a practical application of myinvention.
The receiver or sound casing 1 includes an outer or shell portion 2 and an inner or cap member 1 and the said portion and member have interengaging threaded rims 10 and 20 for snugly fitting onto each other and for holding the diaphragm 3, preferably of aluminum, in its operative position over the sounding bar andanvil, as is clearly shown in Fig. 3 of the drawings.
4-4: designate the current receiving mag? nets and, in our construction, the said magnets are adjustable to and from the armature bar 12 by adjusting screws 5 that engage the' threaded stems 50 on the magnets, and which pass through the metal base '11 to the outer or bottom side of the casing 1, as is best shown in Fig. 8.
A sounder bar 7 is hung on pivot screws 8 that take throughstuds 8080, and which project from the base 11 (see Fig. 6).
The free end of the sounding bar 7 plays in the notched end of the sounding anvil 62 and the swing of the said free end of the sounder isregulated by a delicate screw adjustment 90, it being understood that the set of the said screw provides for in I -gages the anvil 62 and-serves for regulating the tension of a delicate pull back spring 60, presently again referred to. I r
The armature 12 is in the nature of a soft iron member that is transversely mounted upon the sounder'bar 7 and is secured thereto by-a screw 13 and the said armature member, as also the sounder bar 7, are normally swung up from the magnets by a delicate spring tension 60 attached to the inner end of the screw 6 and a lug 71 pendent from the sounder at a point slightly in advance of its pivot (see Fig. 3) and to further provide for a delicate adjustment of the sounder, relatively to the pulling energy of the magnets,an adjustable counterpoise 70 is attached to the rear or heel end of the sounder, as is best shown in Figs. 3 and 5.
14.-14 are laterally projected studs on the casing to which the head band connects, as shown. 1
aa indicate the binding-posts or termi nals with which connect receiving and re turn cables or lines through which the electric current is fed and carried away from the instrument. 7 r
In practice, our improvement operates in series with the relay so as to do away with a separate set of batteries.
From the foregoing description taken in connection with the drawing, the complete construction, the manner in which our in vention operates and its advantages will be readily understood by those skilled in the art to which the same relates.
Among the advantages, it should be stated, by using a telephone head receiver casing with a diaphragm for cooperating with a sound producing element and the latter adjustably mounted as described and shown, the sounds produced by the hammering of the sounder arm against the anvil will be audibly augmented by the said diaphragm, which reproduces the sound with clear clicks.
By mounting the sounding anvil so it may be slid in the direction of the length of the sounding arms 7, the signals or sound clicks can be rendered of greater or lesser loudness and, by reason of the delicate screw stops 90 on the inner end of the anvil, the stroke of the sounder arm can be regulated so as to be capable of producing signals so delicate that they can be heard only by the application to the ear of the operator, it being understood that by the aid of the diaphragm, the delicate signals are made so distinct that the character of the signals are not readily misunderstood.
Y Vhat we claim is:
1. A telegraph sounder of the head type, comprising a casing made of two sections, screwing one onto the other, a sound transmitting diaphragm held between the meeting edges of the two sections, an electromagnet sound producing means located withthat extends over the free end of the armature sounder bar.
2. 'A telegraph sounder of the head type, comprising a casing made of two sections, screwing one onto the other, a sound transmitting element held between the meeting edges of the two sections, an electro-magnet sound producing means located within the casing and under the sound transmitting element, the said electrO-magnet sound producing means including an armature sounder bar, an anvil engaged thereby, the said sounder bar being pivotally mounted and provided at one end with a counterpoise, the anvil having a notched portion that extends over the free 'end of the armature sounder bar, and an adjustable stop mounted on the anvil for limiting the swing of the clicking end of the armature sounder.
3. An instrument of the character stated, comprising a casing including a removable ring shaped cover, sounder devices located within the casing, the said devices including a magnet, a sounder bar that extends across the magnet, the said bar including an armature portion for cooperating with the magnet, means for adjusting the magnet to or from the said armature portion, the said sounder bar being pivotally Imounted, a spring tension for holding the said sounder bar to its magnet release position, an anvil having a notch into which the free end of the sounder bar extends, and means on the anvil for regulating the extent of the hammering. movement of the striking end of the sounder bar in the notch of the anvil, and an adjustable counterpoise attached to the heel end of the sounder bar.
