GEORGE STAM'PER PERRY, OF BRANFOBD, FLORIDA.

TELEGRAPH-KEY.

Specification of Letters Patent.

Patented Sept. 28, race.

Application filed. January 28, 1909. Serial No. 474,674.

To all whom it may concern:

Be it known that I, Gnonon Srmtrnn Puimv, a citizen of the United States, residing at Branford, in the county of Suwanee and State of Florida, have invented a new and useful Telegraph-Key, of which the following is a specification.

This invention relates to telegraph transmitters and more particularly to an attachment for relieving the operator of the strain incident to transmitting messages under the well known Morse system.

The object of the invention is to permit the sounding of a lettercomprising a plurality of dots with a single movement of the operating lever, thereby to expedite the transmission of messages and at the same time relieve the operator of the strain clue to the necessity of imparting a plurality of strokes to the operating key to produce such letter.

A further object is to provide an instrument capable of sounding either dots or dashes, and which may be used, either in connection with or independent of the usual form of telegraph key.

A further object is to provide an instrument of the character described, the construction and operation of which is such as:

to permit a solid contact between the platinum pointer, and which may be adjusted to make either light or heavy dots or dashes.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and ei'liciency.

Further objects and advantages will appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

In the accompanying drawings forming a part of this specification:Figure 1 is a alan view of a tele ra 3h transmitter constructed in accordance with my invention showing the position of the parts when making a dash. Fig. 2 is asimilar view showing the position of the parts when making a dot. Fig. 3 is a longitudinal sectional view taken on the line- 3-3 of Fig. 2. Fig. 4: is a similar view taken on the line 4t4; of Fig. 2. Fig. 5 is an end elevation. Fig. 6 is a transverse sectional view taken on the line 66 of Fig. 2. Fig. 7 is a perspective view of the oscillating contact member detached.

Fig. 8 is a similar view of a portion of the vibrator. Fig. 9 is a top plan view illustrating a modified form of the invention. Fig. 10 is a side elevation of Fig. 9. Fig. 11 is a transverse sectional view taken on the line 11 11 of Fig. 10.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The telegraph transmitter forming the subject matter of the present invention comprises a base plate 5 to which is secured a relatively short side wall 6 and an end wall 7, said walls being connected by a top plate, indicated at 8.

Pivotally mounted on a stud 9 extending vertically from the base is a key lever 10, one end of which is provided with a vertical extension 11, while the other end thereof projects longitudinally beyond the pivot 9 to form a finger piece 12.

Extending longitudinally of the base above the operating lever 10 is a vibrator 13 having its inner end formed with an enlarged head 14, which latter is pierced by a pivot pin 15, the terminals of which are conical in shape and engage correspondingly shaped sockets formed in adjusting screws 1.6 and 17 carried by the cap-piece 8 and base 5, respectively, as best shown in Fig. 3 of the drawings. This vibrating lever 13 is preferably formed in two sections, the main section 18 of which is formed of relatively stiff material having a slight spring action and the auxiliary section 19 formed of relatively thin material, so as to permit the latter to readily vibrate.

Extending transversely through the

secions

18 and 19 of the vibrating lever, at the junctureof said sections, are one or more rivets or similar fastening devices 20 which serve to hold the sections rigidly in longitudinal alinement with each other.

An oscillating lever 23 is pivotally mounted on the platform at 2% and is provided at one end with a bifurcated terminal 25 which receives an adj usting screw 26 extending laterally from the inner end of the main operating lever 10. e

The contact 22 of the oscillatin lever is provided with a platinum point 21 for en gagement with a similar platinum point 28 carried by an adjusting screw 29 threaded in the'side wall 6, one terminal of the circuit being connected with the clamping nut of the contact 22 and the other terminal thereof connected with a binding screw 30 on the member 29.

Extending laterally from the head 14 of the vibrating lever is a pin 32 to the free end of which is connected one end of a coiled spring 33, the opposite end of which is connected with a pin or stud 34, said spring serving to return the vibrating lever to normal position after the

platinum points

27 and 28 contact with each other to make a dot. A coiled spring 34 is also preferably interposed between the wall 6 and the oscillating lever 25 for returning the latter to normal position after each operation of the finger-piece. Thus it will be seen that by moving the finger-piece 12 laterally in the direction indicated by the arrow shown on the finger-piece in Fig. 2 of the drawings the extension 11 of said lever will engage the section 18 of the vibrator and force the latter against the contact 22 of the oscillating lever 23 thus tilting said lever and causing the platinum point 27 of the oscillating lever to close the circuit through the platinum point 28 of the adjusting screw 29 and sound a dot.

The vibration of the lever 13 will cause the

contacts

27 and 28 to intermittently open and close the circuit, the number of dots produced at each movement of the finger piece 12 being in proportion to thenumber of vibrations of the lever 13.

Slidably mounted on the section 19 of the vibrator is a weight which governs the vibration thereof so that by moving the weight longitudinally of the section 19 and clamping the same in adjusted position by tightening the screw 36 the number of dots sounded at each movement of the lever 12 may be governed at will.

" bration of the weight 35 after the hand of The inner end of the finger piece 12 is provided with an over-hanging cylindrical arm 37 on which is loosely mounted a sleeve or collar 38, which latter serves to stop vithe operator has been removed from the finger piece 12.

By moving the finger piece 12 in the directlon, indicated by the arrow in Fig. 1 of the drawings, the extension 11 will be disengaged from the vibrating lever and the oscillating lever 23 actuated to produce dashes.

The screw 26 is provided with an enlarged head 38 which bears against a stop screw 39 threaded in the wall 6, there being a washer 40 interposed between the head 38 and the adjacent side of the oscillating lever to assist in preventing the head 38 from passing through the bifurcated portion of said lever.

By arranging the several parts in the manner described, a firm solid contact between the platinum points 27 and 28 is assured, the line up or adjustment of the main lever 12 and vibrating lever as well as the length of stroke of said levers being obtained by manipulating the

screws

26 and 39 and eitherlight or heavy dots or dashes by adjusting the screw 29-. Thus it will be seen that by moving the finger piece 12 in one direction, the instrument may be utilized for sounding dots, while by moving the finger- If desired, the attachment may be used in connection with an ordinary telegraph key and for this purpose one side of the base 5 is formed with a segmental recess 41 intersected by a longitudinally disposed groove 42, preferably dovetailed in cross section, and

in which is mounted for sliding movement a wedge shaped key 43.

When the device is used in connection with a telegraph key the frame. of the key, indicated at 44 in Fig. 1 of the drawings, is positioned at the segmental recess 41 with the finger-piece 44 thereof adjacent the finger-piece 12 and in convenient position for manipulation by the operator, the operator first operating the finger-piece 12 of the present attachment to sound the dots in the Morse alphabet and then operating the finger-piece 44 of the ordinary telegraph instrument to produce the dashes. As before stated, however, the attachment is complete in itself, and may be used for sounding both dots and dashes.

The attachment is clamped in position on an ordinary telegraph key by'moving the locking key 43 longitudinally within the slot 42 until the recess or depression 43 of said locking key passes beneath the adjacent pivot screw 45 of said telegraph key, as best shown in Figs. 1 and 6 of the drawing and in which position the attachment will be locked against accidental displacement without the employment of screws, clamps and similar fastening devices.

The device is very sensitive and the parts thereof may be adjusted to produce sounds corresponding to light or heavy dots or dashes, while the weight 35 may be adjusted to produce any desired number of vibrations and thus permit the sounding of any number of dots at one operation of the finger-piece.

Special stress is laid upon the fact that by means of the oscillating lever 23 and platinum points 27 and 28 a firm solid contact is insured at each movement of the main operating lever, while by manipulating the adjusting screws 26, 29 and 39 not only, may the throw'or stroke of the main and vibrating lever be regulated at will but the contacts adjusted to make either light or heavy dots or dashes.

In Figs. 9 to 11 of the drawings there is illustrated a modified form of the invention in which the side and end walls of the supporting base are dispensed with, the head 47 of the vibrating lever 13 being pivotally mounted in an over-hanging bracket 48 secured to one end of the supporting base. In this form of the device the key lever 10 is made relatively thin and of substantially the same cross sectional diameter throughout its entire length, one end of said key lever being provided with a finger-piece 12 similar in construction to the finger-piece shown in Fig. l of the drawings, while the opposite end thereof of the key lever is connected through the medium of a link or plate 49 with the oscillating lever 23.

The upper lon itudinal edge of the connecting plate or link is formed with a longitudinally disposed slot 50 for the reception of a clamping screw 51, which latter is threaded in the adjacent end of the oscillating lever 23, the movement of the oscillating lever 23 being regulated by a screw 52 threaded in the angular extension of the plate 19 and engaging the shank of the screw 51, as best shown in Fig. 11 of the drawings.

Suitable lugs or brackets 53 and 54.- are secured to the supporting base at one longitudinal edge thereof and provided with, threaded openings for the reception of correspondingly threaded

screws

55 and 56, one of which is provided with a contact 57 for engagement with the contact 58 of the oscillating lever 23, while the other screw 56 by engagement with the screw 52 forms an auxiliary stop for said oscillating lever.

Extending laterally from the head of the key lever 13 is a pin or lug 59 to which is secured one end of a coiled spring 60, the opposite end of which is attached to a cord or other flexible medium, which latter is secured to a screw 61 threaded in the oscillating lever 23. The spring 60 serves to return the vibrating lever, key lever and 0s cillating lever to normal position after the finger-piece 12 has been actuated to make either dots or dashes. The lower face of the oscillating lever 23 is preferably cut away, as indicated at 61 so as not to interfere with the action of the spring 60 when said lever is oscillated.

As the construction and operation of the device'shown in Fig. 9 is otherwise similar in construction to that shown in Fig. 1 of the drawings, further explanation of the same is deemed unnecessary.
