8 Claims.

This invention relates to code sending and recording apparatusand has for an object to provide an insulated wire and electrical means 7 under control of a telegraph key for scraping 03 the insulation in the form of dots and dashes whereby to effect the recording of a message.

A further object is to provide a switch contact having wiping contact with the indentations in the wire formed by the knife and an audible sisnal device in circuit with and controlled by the switch contact to reproduce the dots and dashes.

A further object is to provide code sending and recording apparatus which will be formed of a few, simple, durable and inexpensive parts which will be easy to manufacture and will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the accompanying drawings forming part of this specification,

Figure 1 is a side elevation of code sending and recording apparatus constructed in accordance with my invention.

Figure 1.

Figure 3 is an end elevation of the parts shown in Figure 2.

Figure 4 is an enlarged detail elevation showing in the various views, the device is shown to com-, prise a base plate In from which rises a standard II having a shelf l2 projecting from the front face and bracedby wings I3. The shelf forms a support for tubular wire guides ll which are ar- 5 ranged in alignment and are spaced apart at the Figure 2 is a plan view ofthe parts shown in Figure 7 is a detail sectional view showing the characters of reference designate similar parts inner ends, Rollers II are disposed at the ends of the support I! and form antifriction bearings over which preferably enamel insulated wire II is fed through the tubular guides ll from a supply spool il to a take-up spool i3. these spools 5 being mounted on bearing arms I! and 20 carried by the standard II. The spools are interchangeably mounted on their shafts 2| and are held in place by'thumb nuts 22 screwed on to the ends of the shaft in the usual manner.

By now referring to Figure 5 it will be seen that between the tubular guides N there is disposed an anvil 23 which is provided in the top face with a groove 24 to receive the insulated wire I6.

A knife blade 25 is disposed above the anvil and is provided midway between the ends with a curved sharp edge 23 which receives the wire when the knife descends and scrapes off the insulatlon from the wire as the wire passes along 20 the anvil from the supply spool to the take-up spool. The knife is provided with a U shaped arm 2'! which embraces the shelf or support i2 and one leg of the arm is equipped with an armature 28 which is disposed below the support in 25 vertical alignment with the knife. The other leg of the arm is considerably thickened above the knife blade as shown at 23 in Figs. 5 and 6 and is provided with hinge ears 30 to receive the pivot pin 3i of an arm 32 which is pivotally connected 30 at the upper end to a spring arm 33 as shown at 34 in Fig. 5. The arm 33 is adjustably mounted upon a bracket arm 35' carried by the shelf or support l2. The knife is thus hung or suspended over the anvil by the spring arm 33 which nor- 35 mally holds the knife blade raised or in released position. The spring arm 33 is adJustably confined in a slotted enlargement 36 in the upright arm 35, by means of a set screw 31.

a Underneath the shelf or support ii an electromagnet 38 is secured to the standard II by means of a bracket 39. The core 40 of the electromagnet is disposed in vertical alignment with the armature 28 and when-the electromagnet is energized the armature is attracted and moves the the wiring knife downwardly to intercept the insulated wire during its travel along the anvil and scrape the insulation from the wire. When the electromag net is deenergized the spring arm 33 moves the knife out of contact with the wire into raised or released position. The terminal wires ll of the electromagnet are led to a Socket 2 carried by an insulating base 43 mounted on the base plate I0. I

The terminal wires '44 from a telegraphkey 4i and battery It may be pl kged into the socket 42 as shown diagrammatically in Figure 9 so that when the key is depressed the knife will be held in contact with the traveling insulated wire II,

and when the key is released the electromagnet substituted for the knife 2! by removing the pivot pin II to disengage the arm 21 from the arm 32, and the pivot pin may now be passed through the hinge eyes ll which are on the switch contact 41 to secure the contact to the arm If. A- flexible wire." is connected at one end as shown at Ii to the spring arm 33 and the opposite end is equipped with a plug I! which may be plugged into a socket il in the insulating base ll to connect the contact in circuit with a buzzer I! or other audible signal device as shown diagrammatically in Figure '9. 'I'he switch contact 41 is spring pressed by the arm a to have wiping contact with the wire It as shown in Figure 8 and during travel of the wire the guide tubes orientthe wire to dispose the indentations underneath the contact so that the indentations, corre- .':sponding to the dots and dashes, will operate the buzzer II to reproduce the code message.

A motor I is mounted on the base plate It and the pulley ll of the motor is connected by abelt II toa pulley 51. on the shaft II of the take-up spool II. The motor may be wired to a socket It on the insulating base so that a flexible cable orcord from the house circuit may be plugged in to operate the motor. A brake N,- as best shown in Figure 1, is mounted on the base plate I. and frictionally engages the rim of the supp y 9001 "to retard the speed of this spool while the wire I6 is being unwound therefrom so that the wire will be held taut at all times during travel over the anvil fl.

From the above description it is thought that the construction and operation of my invention will be fully understood without further explanation.
