are attached to the base 30 and bear upon the upper edges of the Operating levers 1, 2, 5 and 6 respectively.

The type blocks 9 and 10 each carry rigidly attached to their under surface three printing elements or types arranged as shown in Fig. 2. Printing elements 1', 2 and a are each divided into four arbitrary units of length while printing element 3 is, when measured lineally along the type block 10, four of these arbitrary units in length.

Type element 2 is spaced on type block 9.

as shown a distance of two units of its length removed from type element 4*, while type element 6 is spaced on type block 9 a distance of five units away from type element 1- Type element 1 is spaced on type block 10 a distance of one unit of its length away from type element 3 while type element is spaced a distance of six units from type element 3 Type blocks 9 and 10 are carried on the operating levers 1, 2, 5 and 6 in such relation to each other that type element 3 is separated lineally from type element 4* by one unit of type element length.

A. prism-shaped anvil 27 is placed opposite the type blocks 9 and 10 and presents three printing faces to the printing elements. A screw 28 serves to adjust the anvil in its distance from the printing types.

A tape 27 sensitized with any chemical compound for electrolytic printing, rests on the surface of the anvil and is carried longitudinally over the printing faces of the anvil by means of the set of rollers as shown.

A form of transmitter is shown at the right of Fig. 1 and comprises a pair of direct current dynamos 17 and 18 or other source of current, their terminals of opposite polarity being connected together and to ground 26, while the positive terminal of dynamo 18 is connected to brushes 19 and 19 and the negative terminal of dynamo 17 is connected to brushes 19 and 19 A flexible brush 20 is of sufficient width to bear upon both brushes 19 and 19 and make contact therewith. A brush 21 is of suflicient width to bear upon both brushes 19 and 19 and make contact therewith. Brushes 20 and 21 are connected to line conductors 24 and 25 respectively and are normally held out of contact with their adjacent pairs of brushes by transmitting tape 29.

It will be noted that by a proper transverse spacing of the perforations in the transmitting tape 29 with respect to brushes 19 and 19 a positive or negative impulse may be sent over line conductor 24: through electromagnets 11 and 16 to ground, thereby as hitherto noted reversing the polarity of one of the magnets of that pair from its normal polarity induced by" the field solenoid 23 and cause the release of its respective operating lever which under spring tension rotates type block 9 or 10 as the case may be, dependent upon the polarity of the operating impulse, to bring either printing type 1 or 6 into contact with the recording tape 27. By a proper transverse spacing of the perforations in tape 29 with respect to the brushes 19 and 19 a positive or negative impulse may be sent over line conductor 25, through electromagnets 12 and 15 to ground to cause the release of either operating lever 2 or 5 to rotate type block 9 or 10 to bring type element 2 or 5 into contact with the recording tape 27. A positive impulse over line conductor 25 and a simultaneous negative impulse over line conductor 24. will operate operating levers 1 and 5 to carry type block 10 downward with a movement of translation to bring type element 3 into contact with the recording tape 27, while a positive impulse over line conductor 24 and a simultaneous negative impulse over line conductor 25 will operate operating levers 2 and 6 to move type block 9 downward to bring type element 4: into contact with recording tape 27. Thus it will be observed that by a predetermined transverse spacing and grouping of the perforations in transmitting tape 29, either type block 9 or 10 may be rotated to imprint its type element borne near its extremities or either type block may be moved downward substantially without rotation to imprint the type element borne near its middle portion.

Referring to Fig. 2 which may be considered to be an enlarged view of the impressions of the type elements as they would appear were all of the types imprinted on a motionless receiving surface, types 1, 2 3 and r are each in length equal to the width of a complete normal character such as H. The width of a complete normal character is divided into four arbitrary units, while the types are separated from each other longitudinally by one of these units as has been hitherto explained.

Fig. 5 shows a sectional transmitting tape 29 perforated to send all oii the characters necessary to transmit intelligence in the Roman alphabet. The longitudinal lines -1, +6, 2, and +5 correspond to the lines of contact of the brushes 19', 19 19 and 19 with the brushes 20 and 21. The transverse lines are spaced a distance apart equal to or proportional to the unit of length of the printing elements 1, 2 3 and 1 dependent upon the ratio of the speed of the transmitting and receiving tapes. Thus a perforation along the line 1 in the transmitting tape 29, will cause the imprinting of type element 1, while a perforation along theline +6 will imprint type element 6. A perforation along the line 2 will imprint type element 2 and a perforation along the line +5 will imprint type element 5". Perforations along the lines +1 and +5 and opposite each other will imprint type element 3 while perforations along the lines -2 and +6 and opposite each other, will imprint type element l Conceive now the tape 29 to move from right to left as viewed in Fig. 5 between thebrushes20 and 21, and 19, 19 19 and 19 of Fig. 1 at a speed which allows one.

sending simultaneous positive impulses of current over line conductors 24; and 25v through magnets 15 and. 16 counterclockwise to release operating levers 5 and 6 to rotate type blocks 10 and 9 respectively to simultaneously imprint types and 6 upon the recording tape27, and after tape 29 has moved through the transmitting brushes adistance of four tape intervals, a slmllarly.

placed pair of perforations allow contact to bemade through the same brushes as before with line conductors24 and 25, again sending simultaneous, positive impulses counter clockwise through magnets 16 and 15, again imprinting type elements 5 and 6 on the recordin tape 27 a distance away from the previous imprints of four units, or the width of a normal character.

pair of perforations placed along the lines --2 and +6 and opposlte each other, allow a negative lmpulse of current and a positive impulse of current to be simultaneously sent over conductors 25 and. 24: respectively,

through magnets 12 and 16, thus cruising operating levers 2 and 6 :to move type block 9 vertically downward to imprint type element 4* on the recording tape 27. This imprint abuts at its extremities the two pre vious sets of-imprints as these two imprints have been carried by the receiving tape a distance of five units of tape length, previous to the imprinting of type element 4*. After the transmitting tape 29 has passed through the brushes ofthe transmitter, a

distance of six tape intervals, a perforation along the line 1 allows a negative impulse of current to be sent over line conductor 24 through magnet 11 in a counterclockwise direction to imprint pen face 1 which as the previousimprints' on -the receiving tape 27 have been carried from right to left a distance of six units of width since the last imprint allows the extremities of the imprint of type element 1 to abut at its extremities, the previous imprints of After tape 29- has passed through the transmitting brushes a distance of five tape intervals, a.

type element 5 thus forming the letter A as shown. in Fig. 5. The characters are separated from each other on the recording tape by a distance of four tape units or the length of a. complete normal character. Thus in imprinting the character B after imprinting the character A, the left hand vertical ofletter B is imprinted by perforations along the lines +5 and +6.0pposite each other and a distance of four tape intervals from the perforations which cause the imprinting of" the right hand vertical of letter A. This causes an overlapping of the sets of perforations in the transmitting tapefor a series of characters, The spacing between any two characters is provided in the transmitting tape preceding the letter or'character to be imprinted as in the case ofthe letter D which is a double spaced letter or'twice the width of a normal character; The perforations to imprint the left which cause the imprinting ofthe right hand vertical of the previous characterfas the character D to distinguish it from the character O is provided with an imprint from type element 2 which causes it to become *a double spaced character with the normal spacing between it'and the prevlously 1mprlnted character of the chosen four units of. length of a normal character. Similarly vall of the'characters necessary to transmit intelligence in the Roman alphabet may be recorded.
