(01. ism-6.1) 1 ment that the actuation of one part‘pnly pro‘ duces one ‘sound ‘tone while the actuation of both produces 'a distinguishable sound tone. An'other feature‘of the invention resides in‘the The invention relates to apparatus for em bossing characters so as to be readable by touch and to devices for translating such characters into sound, as well as to tapes embossed with completed tape itself, which has been‘ described such characters. It is particularly intended for use by blind persons. above. ' by the blind" is the well-known Braille‘.

" Further objects and advantages of thisinven tion will‘ be apparent from‘ the accompanying The usual type of matter intended to be read ' .bodimentof my invention; ‘ - a’ ‘ Figs. 2- and 3 are cross sections generally along 15 A second object'of the invention is to provide a simple and effective device for ‘embossing such thelines'z-2'and 3~—-3>of~Fi-g.1;' ~ ' - ~ - Fig. '4 is a detail of the spacing mechanism‘: ; > Figsi? ‘and 6 show‘two types of tape embossed in accordance with-the invention; \ ~ symbols on a tape or the like, particularly a de Fig. 7 is an end view of a reading device-ac vice utilizing only two keys and a spacing mem » ‘ ' ber. It includes an arrangement by which both 20 cording‘ to theinvention; r Fig; 8 is a cross section on the line 8-’-8 of symbols are in the same line longitudinally of the Fig.7;and' ~ -~ tape, at least in part, so that the ?ngers of a reader moving along the tape need follow only this line to detect all of the symbols. The dan ger of missing some of the symbols is thus greatly reduced, and the ease and accuracy of reading are increased. ‘In this respect, the invention contemplates the use of two members arranged side by side in the direction of movement of the tape, with a mech anism for causing such members‘ to emboss the successive symbols at proper intervals. An additional object of the invention, in con nection with such an embossing mechanism, is the arrangement of the tape feeding mechanism ‘ in such a way as to clear the embossing at each stroke of the machine, this being preferably ac complished by arranging rollers on opposite side of and above the embossing anvil. The invention further includes a device for reading a tape so printed. One object of this de vice is to provide an audible tone of di?ering sound for each type of symbol, so that the listener can easily follow the message on the tape as it is fed through. A further object of this device is to prevent the transmission of impulses to the sound emit ting apparatus by creases or seams in the tape. Still another object is to provide, in connec tion with the type of tape described above, hav- ' ing parts of all symbols in the same line longi tudinally of the tape, parts actuated‘ by projec tions in different horizonta1 lines, one of which is actuated by all the‘symbols and the other by only one type of symbol; with such an arrange; 55 Fig.9isatopplanviewthereof. ' ' . : l The embossing mechanism‘ includes a~frame 2-.‘ .At the. ends of ,the- frame‘ are blocks provided with guide‘ channels 4 for a paper strip‘on which the embossing is to be done. Between these channels the paper passes “over idling guide roller 6 and between guideroller-S and driving rollers l0.» Between "these' two sets of rolls the- paper passes above an'anvil l2 having thereon dies or impression "blocks I4, I 6 for the two types of symbols. Preferably, as shown in Fig. 5', these are ‘dots and dashes, with the dashes running transversely of the strip, but partly‘in the same line longitudinally of the strip as the dots. The movable printing. members are ‘rods 18, 20 having recesses:mating with the projections of dies I4~and~l6. These rods are pivoted at 22 toguide-links 24 which are: pivoted at 26 to the-machine frame. They are also pivoted at 28, 30 to levers 32,313, respectively. » These levers are mounted'to turn freely on ‘a rotatable shaft $5.,v Pawls .38, 40 on the two levers'en'gageable with ratchets-H, M- rigid- with shaft, 36 cause the shaft to turn- counterclockwise (Fig.1) when ever one of- the levers turns counterclockwise, ‘but allow the shaft to remain stationary when the levers'turn clockwise:v ‘ ‘ ‘ - Rigid. onvshaft??v is a pinion .46 which meshes with a pinion 48 connected to paper driving roller l0, ‘so as to move‘ the-paper'to the left (Fig. ‘1) when the shaft 36 turns counterclock w1se_ ,. , ‘. .. .1 . ,- ‘i The frame 2 carries-two‘ upright posts 50 pro‘ ‘ I‘ ' 2,412,183 3 4 vided with vertically extending guide slots 52 of T-shape.

On the other end of lever ‘I8 is pivoted a lever 82 movable from the dotted line position to the ‘solid line position and dashes. where it is held by a stop 84. - ' - . ' , Mounted on blocks 56, 58 and on the frame are pairs of contacts 86, 88 connected to two electric buzzers 98, 92 of different tone by a suitable elec tric circuit.‘ ‘ ' At its free end, lever II 6 has a laterally extend ing contact ‘arm I38 electrically connected to a buzzer I32. Arm I I8 has a contact I34, connected to a battery I36, in the path of contact I 38. Cross piece I22 carries a contact I38 in the path of contact I34 and connected to a second buzzer I48 of different tone. ~ ‘ .This mechanism operates as follows: ' The device operates as follows: , ~ When the dot key 68 is depressed, roller 62 en gages lever' 32 and moves it counterclockwise. Pawl 38 and ratchet 42 turn shaft 36 and drive roller I8, causing the tape to move forward one space.

Finally, rod I8 pushes the paper both noses I24 and I 26 and. raises levers H6 and against die I4 and embosses a dot on the strip. H8.

' also move contact I38 out of reach of contact I34, I . It will thus be noted that after each operation 40 While I have described herein one embodiment the blank space for receiving the next impression of my invention, I wish it to be understood'that I do not intend to limit myself thereby, except is above the rear die, in this case the dash die. within the scope of the appended claims. . ' If a dot is to be formed, this'blank space is fed forward before printing takes place into posi tion over the dot die. For a dash. the space re mains stationary until printing has taken place and is then fed forward. . It will also be noted that the plane joining the engaging points of the rollers which guide the tape is located above the tops of the dies. When feed roller I8 draws on the tape it thus‘ pulls it ‘up off the dies so that movement of the tape is not interfered with. ‘ . For spacing, the lever 82 is pushedto the right ‘(Fig 1) which through pawl 16 turns roller I8 to ' ' advance the tape by one space. ‘If a check is desired on the symbols, switch 94 may be-closed and the operation of either key will ‘produce an audible signal so that the user can detect an error in printing. This is-also an aid to learning the code and especially to learning to read with the reading mechanism. The vreading mechanism for such a tape is "shown in Figs. '7 to 9. The tape itself, shown in “Fig; 5, in the preferred form has short symbols or dots and long symbols or ‘dashes, the ‘latter differing from" the dots by their greater length transversely of the tape, but lying partly in the same longitudinal line.
