Application filed. Februz'try 4, 1907. Serial No. 365.568.
To all whom it rnay concern:
Be it known that I, JEROME P. ZELENKA, a citizen v and specifically claimed.
The principal object of the invention is to provide a of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Telegraphic Instruments, or which the following is a specification.
This invention relates to telegraphic instruments of a type by means of which messages may' be taken or received silently and directly by the sense of touch, and it consists in certain peculiarities of the construction, novel arrangement, and operation of thevarious parts thereof, as will be hereinafter more fully setiorth telegraphic instrument, whichshall be simple and inexpensive in construction, strong, durable and ellicient in operation, and so made as to provide means'to enable telegraph operators (even if deaf) to receive messages or despatches through the medium of direct touch with the human body, and when desired, without the use of Sounders, indicators or impressions on paper, and thus secure greater secrecy, rapidity and accuracy in the work of receiving the same, as well as, enabling operators who may be deaf and blind to receive messages or act as operators.
Another object of the invention is to so construct the instrument that it may be readily secured to one of the wrists or hands of the operator to the end that he will be enabled to secure direct, distinct and perfect trans mission of the electric impulses, and further, so that he may use the other hand to write out or send messages.
Other objects and advantages of the invention wil disclosed in the subjoined description andexplanation.
In order to enable others skilled in the art to which my invention pertains, to make and use the same, I will now proceed to describe it, referring to the accompanying. drawing, in which I Figure 1 is a perspective view of a hand and wrist,
. showing-a telegraphic instrument for receiving messages and embodying my invention secured to the wrist, and also illustrating a transmission key or device securcdon the wrist. Fig. 2 is a bottom. plan view of the instrument with the lower plate of the casing or holder removed, and illustrating the electromagnets and spring actuated armature in place within the casing. Fig. 3 is a longitudinal sectional view takenon line 33 of Fig. '2 looking in the direction indicated by the arrows, but showing the bottom plate of the casing in position thereon. Fig. 4 is a detached perspective view of the spring which carries the armature and adjustable screw for contact with a portion of the human body; and Fig. 5 is a view in side eleva tion of a transmission key, which may be used in connection with the instrument.
Like numeralsof reference, refer to corresponding parts throughout the different views of the drawing.
'The reference numeral 10 designates the holder or casing for the various parts of the instrument, which holder or casing may be made of any suitable size,
form and material, but preferably oLmet-al and rec-fill) tangular or box-like in shape. As shown in the drawing, the bottom of the casing or holder 10 is closed by means of a. curved plate ll, which is provided on its lower surface with a sheet of felt 12 or other suitable material to rest on the wrist or hand. .13 or the operator or user. The curved plate 11 is provided at each of its side edges with an upturned portion 14, through an opening in each of which a screw 15 is .1 the sides of the casing or holder plate 11 in position thereon, as will be od which engage secures the stood by reference to Fig. 1 of the l win At each of its corners, the plate-ll is provided a an upturned hook 16 which are adapted to eng loops 1'? on the ends of bands or straps 18, which mymade of elastic material and extend arou l the Near one of its ends, the bottom plate ll, as well as the felt or material 12 thereon, is'provided with an opening 19, for the purposeto be presently explained. Located longitudinally'in the holder or casing 10, and secured thereto at one of its ends, is an electro'rnagnet;
20, of the ordinary-or any preferred construction, the coils 21 of which are electrically connected to binding posts or screws 22 which are located in a block of insulation 23', such as fiber or other suitable material, $5
electric or electro-magnetic currents (not shown) are $0 conductors 24 and 25, of the ordinary kind.
As shown in Fig. 2; the coils 21 comprising the magnet 26 are spaced apart in parallelism, and have located between them the body of-a spring 26, which is preferably oi the construction shown in Fig. l, that is to'say', it has one of its ends bifurcated, theprongs 27 of which are secured by meansof screws 28 or rivets. to the inner upper portion of the casing 10. I The bifurcated portion of the spring 26 lies against the inner surface of the casing 10, and the' body portion is bent to approximate the portions 27 and extends to near theend of the casing 1'0 opposite that on which the binding posts or screws 22 are located, and is provided at its tree portion with an arm or bracket 29 which has its free or lower end, when the instrument is in position for use, inwardly bent as at 30 (see Figs. 3 and 4 of the drawing). The inwardly bent portionfifl is provided with an apertured boss 31 to receive a contact screw32, which preferably has its head ii y under- 70 wrist 7 5 so as to hold the casing or holder 10in position. thereon.
; erator or user. At its free portion and at the juncture of the arm 29 with the spring 26 is transversely secured, on the spring, an armature 34, which has on its surface adjacent to the top of the casing 10 cushions 35, of any suitable material, to prevent noise or clicking should the armature strike said portion of the casing. The spring 26 is so formed or adjusted as to hold the armature 34 in such position that it will be normally out of contact with the magnet, but capable of being attached thereby for the production or development of signals or impulses upon the passage of a proper current and 'in order to prevent the armature giving forth any sound, the spring 26 may he so formed that the armature will be normally held almost in contact with the magnet, or at such a slight'distance therefrom that the noise or click produced by its contact with the magnet will be virtually inaudible. p I
As shown in Figs. 2 and 3, the contact screw 32 is located on the arm 29 of the spring 26, which arm extends from about the middle of the armature 34, so that the screw 32 may pass through the opening 19 in the bottom plate 11 of the casing or holder. By employing the screw 32, which as before stated, engages an opening in the portion 30 of the arm 29, it is apparent that it can be adjusted with respect to the hand or wrist of the operator, so that it will give, in the movements of the armature,
a slight or greater pressure or impact thereon, as may be desired.
In Fig. l, I have shown a transmission key secured on the arm or wrist of the operator by means of an elastic strap 18, which has at each of its ends loops 17 to engage hooks l6 on each end of a curved plate 36, which may be lined on its lower surface with felt 37, or other suitable material.
As shown in Figs. 1 and 5 of the drawing, the plate 36 has mounted on its upper surface a'block 38, of insulating material such as fiber or the like, and on one end of this block is secured a spring 39, which has at its iree end a button 40 and a contact screw 41, the latter adapted, when pressure is applied to the button 40, to contact with a binding post 42 on the other end of the block 38,
thus closing and breaking the circuit through the con ductors 24 and 25, which may. he in circuit with the conductors 24 and 25 oi the receiving instrument, or
electrically connected with connections for receiving and transmitting messages.
By the use of the transmitting key just above described, it is apparent that the operator receiving a message through an instrument constructed according to my invention, may ask the sender to repeat or may 1. In a telegraphic instrument, the combination with a holder or casing, of an electromagnet carried thereby, a spring secured at one of its ends to the casing or. holder and having at its other end an adjustable screw adapted to project through an opening in the holder or casing and to contact with the human body; an armature transversely secured-on the spring near its free end, substantially as described.
2. in a telegraphic instrument, the comhination with a casing, of means to secure it to'a portion of the body of the operator. an electro-magnet located in the casing, a
spring secured :it one of its ends to the casing and having at its other end an adjustable screw adapted to project through an opening in the casing so as to contact with the body of the operator. and an armature transversely mount ed on the spring near its free end. substantially as described. p
3. in a telegraphic instrument, the combination with a bdx-like casing, of a removable plate located on its lower portion and having an opening therein. said plate having a hook at each of its corners, straps having loops nt their ends to engage said hooks, an electro-mugnet located in the casing, a spring secured at one of its ends to the casing and having at its other end an adjustable screw adapted to operate in the opening of the bottom plate. and an armature transversely secured on the spring near its free end, substantially as described.
