ADOLPH OTTO UBZBAN, F SAN FRANCISCO, CALIFORNIA.

Be it known that" I, ADOLPH O'r'ro URBAN, a subject of fthe Emperor of Germany, residing'inj-the city and county of San Francisco, State. of California, have invented certain new and useful Improvements in and has for its obj ect' the-translatin anisin, known as telegraphic translators,

Telegraphic Translators, of which the foltelegraphic code into characters rea ily understood by anyone, capable of reading. This is done by a series of progressive se- 'lections,

' cessive .positionsin order to select certain "to the bars, making a combination of releases that result in a printed character oftype. To accomplish this I employ mechanism shown in the accompanying drawings, in which- Figure 1, is a plan view of my device, with the cover partly broken away disclosingthe mechanism. .Fig. 2, is a side View thereof. Fig. 3, is a, detail view of the double sliding bar' for carrying thetype printing mechanism. Fig. 4, is a vertical section, showing the selective mechanism, and Fig. 5. is a similar View, showing one. key PI'GSSGD. downward also a front view' of the printing mechanism. 1 and -2, are two keys representing a dot and dash of the continental telegraph code, respectively, mounted on standards 3 and 4,

1 held normallyupward by the springs 5; 'angle bars 6 and 7, are rigidly attached 'to the standards 3 and 4, having at their inner ends connecting links 8 and 8'. These links are pivotally attach'edto radial arms pivotally mounted on the axis'of a small gear 10;

p are of their travel.

at their point of connection, withqthe links 8 and 8, are mounted dogs to engage the teeth of said gears, and move it through the The gear 10, is carried by any; suitable and meshes with" a "rack 11, on the top of the carrier 12. This carrier, has slidably mounted on one side two depressors 1.3 and 14, normally held in their extreme upward position by springs- ,47. and adapted to depress the horizontal "arm of the bell cranks 17, the lower arm of said bell cranks 17, engaging pins 18, on the releasing bars 19 and 20, and causing them to move in a horizontal'direction.

type bar 21, is a head, carrying on its front face the character to be printed. The lower side 22, of the head is similar in shape to an inverted frustnm of a rectangular pyramid, said frustums. 22, resting in receptacles or apertures, identical in shape in the carrier bar 23. This bar 23, hasa horizontal dove-tailed slide 24, in its outer side, said slide 24, having vertical dove-tailed Slides 25, rigidlya-ttached thereto and engaging dove-tailed, slots *ina stationary piece 26, attached to the casing. Springs to their highest position. A handle 55, is attached to one end of the carrier 23. A slot 29 is provided the entire length of the'casing and has an upward extension 29 in its normal position.

A circular disk 30, of any material. suitable for the retention of ink, is carried at one end ofthe casing and is operated by ink rollers 40, 41 operated or rotated by the pawl arm 38 and the ratchet 39, to give an even distribution of the ink.

Between-the disk 30 and the strip 32, is a strip of paper 31, which is passed through the feed rollers 33, these, being operated by the contact of the arm 35, and spring pawl 36, carried on one end of the carrier 23 with the ratchet 34. A spring pawl 37 ,prevents a reverse movement of the feed rollers 33.

'A box or compartment 43 is used to store the paper strip 31.= Y

The continental code is referred to in the following; the bars 19, represent dots and the bars 20, represent dashes. The letters E, T, A, N, I and M, on the top of the type bars 21, represent. the characters to be printed and are not the types themselves. If it is desirous of translating the Morse code into the Roman characters of the alphabet which they represent, it is only necessary to proceed as follows. Should the first character he a dot only, (E), then the key 1, which represents a dot, should be depressed. This carries the anglebar 6, downward, and depresses the depressor 13, which in turn operating through the bell crank 17 and pin 18, moves the first bar a slight distance,= and causes the slot 61, to come under the hook.

keep with at one end, to provide: for the reception of the handle 55, When Q and 42, these in turn being spring hooks. Mounted on one end of the The type bar E is' then released, all the,other openings or notches of the bars 19 and 20 or members 22 fit loosely within the corresponding sockets of the bar'23 in, uch amanner that they are carried with the bar 23 in its journey to the printing mechanism provided that they have first been released from the bars 19. or 20 by the proper selection of the operating keys 1 or 2. The arm 44 is an extension securedto and traveling with the arm 23 and is used for the purpose of supporting the other end of the type bar in its journey to and from the printingmechanism, and-on returnof arm 23 the extension 44 serves to return the outwardly extending portion of the type arm to 'its place, and by servin as a support, in-

sures the engagement 0 the hooks on the type arm with the bars 19 and 20. Inprinti'ng the character ofthe last type arm at the 25 right of Fig. 1 the handle 55 must be moved in the'slot 29 the full length of the machine until the'face ofthe type comes in contactwith the printing disk 30: An opening in the opposite end of the casing is shown on 3 Fig. 2 at the lowerleft hand corner'so that the traveling bar 23 may protrude there- 1 from. After, the selected character is printed on the paper strip 31, the bar 23 is returned to the opposite end of the slot 29, then moved upward into the extension 29 of the slot 29 until the hooks of the type bars 21 spring into position above the bars 19. and 20, the extension 44' serving to support the opposite end of the .type bar'21 from that supported 40 by the traveling bar 23. When the bell crank lever 17 is depressed, a flat spring 49, exerts a downward pressure on the bar 19- (or20 when the dash is pressed) at the same time that it is movedhorizontally. This causes a slight downward movement of said bar 19, and permits a shoulder 51, to engage the ledge on which that endof the bar 19, is

resting. This is to prevent the premature return of. the bar through the action of spring 50. The carrier, 23, 'is 'now brought contact with the 7 pressure, causes the type E'to leave an impression on the paperstrip 31. Returning thecarrier 23, tothe other end of the casing,

down by means of the. handle 55, until it face. 60, of the type bar E, is brought into isk 30, and the resulting it is returned to its upward position by thesprings 27, on the verticalcarrier 25,-and

the type bar E is returned to its position, at the same time lifting the bar 19, disengaging the shoulder 51, and allowing the spring 50 to return said bar19, to its normal position.

Should it be desired to translate a dash,

(representin the letter T) the same operation will sufhce and'the same movements are broughtinto play, with this exception,'when key 2 is depressed, it operates the first of the bars 20, instead of the first bar 19, causing the letter T to be printed. 1

'- Should it be desired to translate a dot and a dash (representing the letter A) the operation is as follows. Press the key 1, which is a dot, and through the mechanism hereinbefore described, the first of bars 19, is moved horizontally, thereby releasing the first hook of the letter E and all other letters whose equivalent in the continental code begins with a dot. The spring 5, returning the key 1, to its normal position, causes the pawl 9, on its return movement to rotate the gear 10, sufiicientlyto move'the selector 12, to a position which will bring both depressors 13 and 14, to the second horizontal bar'in each set (19 and 20). Key 2, representing a dash, is now depressed and the same operation takes place, with the exception of the second bar. 20, being moved horizontally, which brings a space under the hook on type bar 21, representing A, and nioves the space on the same horizontal bar away from the hook on type bar 21, representing E. This releases A and locks E. To return the selector 12, to its normal position, wit-h its depressors13 and 14 over the first bars in 19 and 20, the squaresliding bar 15, on which it is slidably mounted is moved forward against the tension of springs 48, when the tension of spring 16,

will return the selector 12, to its normal position against a suitably located stop. By releasing the bar 15,- the tension of the springs 48, will return the bar 15, and sellector 12, to their proper positions and the rack 11 will mesh with the gearlO. As each key is depressed, one of the pawls 9, serves to prevent the reverse movement of the se- 'lector,'un'til it is unmeshed from the gear 10.

A, being represented in the continental code by first a dot and then' a dash, the type bar 21,. representing A ;will be released 1f the dotkey l,-is p'ressed'first and the dash key 2, ispressed second, as the pressing .and releasing; of the dot key moved the selector 12, to its second position so that the dash key 2, being depressed, operated only the second bar ofthe set marked 29. If the -andv not the other. For instance, the'letter dash key 2, were depressed first, then one hook of N, would be released, its release being partly on the first bar of 20 (dash), and

1f dot key 1, were then depressed the second bar 19, of the dot bars would complete the release. In other words the release for A is found in the first bar of the dot set (19) and the second bar of the dash set (20) whereas, the release for N is found in the first bar of the dash set (20) and the'second bar of the dot set (19). It will then be seen that by operating either a dot or a dash bar, all letters beginning with that character, are partially released, except E or T, which are wholly released. If a second operation is performed it looks E or T and releases A or N, if a third operation is performed, it locks the release of A or N, and releases other letters beginning with the same combination of characters, in the same order of succession, consisting of three characters, and so on through a number of combinations which is only limited by the number of releasing bars employed.

It is obvious from the foregoing, that any combination of dots and dashes may be translated into letters and figures.

While the continental code has been here utilized, it is apparent that the American code could be similarly translated by the introduction of a space key, which would only tend to operate the selector and not operate the horizontal releasing bars.

The details of construction are so susceptible to variations that I do not wish to limit myself to the precise construction shown herein, but rather to avail myself of anymodifications that may properly fall within the scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
