TYPE-WRITING MACHINE.
SPECIFICATION forming' part 0f Letters Patent No. 681,036, dated August 20, 1901. Application filed January 18, 1901. Serial No. 43,788. (No model.)
`To @ZZ whom t may concern.-
Beit known that I, HUBERT BURG, a citizen of the German Empire, residing at Mollkirch, canton of Rosheim, Alsace, in the German Empire, have invented certainnew and uscful Improvements in Type-Writin g Machines,
, of which the following is a specification.
My invent-ionrelates to type-Writing machines in which the printing is eifected by means of characters formed on the periphery of a barrel, to which movements of rotation and translation are imparted.
The object of myinvention is to so arrange the mechanisms as a whole as to provide a machine of this class whichA shall be easy to operate rapidly, simple in construction, and comprising but few keyswhen the large number of characters is considered.
The mechanical arrangements for which I desire toobtain Letters Patent have for their object, in the first place, to impart rotary movements to the barrel by means of asmall number of simple devices, while obtaining at the same time acomparatively large numbertwenty, for example-of positions different as to the direction of displacement, and, in the second place, to avoid any of the parts of the `I3, Fig. 2, the key-levers being removed. Fig.
2 is a plan view. Fig. 3 is a vertical section showing the right-hand side of the machine. Fig. 4 is a part-sectional view on the line C D of Fig. Figl 5 is a vertical section showing the left-hand side of the machine. Fig.
G shows the details of a devicefor operating a carriage movinga threaded sleeve on the spindle ofthecharacteror type barrels. Fig. 7 is afpla'n of an oscillating frame located unr Fig. 8
der the main frame of the machine.
is a detail view of a mechanism for causing the barrels to turn and effect the printing. Fig. 9 is a sectional view of the threaded sleeve.
The type-writing machine shown comprises two type-barrels l and 2, intended to produce simultaneouslyidentical impressions on sheets of paper or a con tinuous strip passing over the rollers 3 and 4. of the carriages 5 and 6; but the machine might comprise a single barrel and a single roller without modifying the principle of my invention. The barrels l and 2 are fixed to a horizontal spindle 7, free to revolve and slide in bearings 8, carried by rods 9, free to move up and down in slideways in the main frame of the machine. In the said spindle 7 is provided a groove 10, serving asa guide for a slidable sleeve 11, the surface of which is provided with a screwthread of long pitch l2. A screw 13, screwed into the sleeve 11 and engaged in the groove 10,' prevents the said sleeve from rotating relatively to the spindle 7.
The characters or types formed in relief on the barrels l and 2 are arranged` in generating-lines and parallel circles. In the machine shown in the drawings each barrel comprises tive parallel circles and twenty generati-ieee, or one hundred characters in all. To bring any one of the said characters above the printing-point it will be necessary to impart to the spindle 7 a movement of longitudinal translation and a rotary movement around its axis. These movements are produced by means of keys pressed by the fingers and divided into three groups. One group of keys 14C l5 16 17 18, placed on the right-hand side of the keyboard, serves to produce the longitudinal movements of the barrels. A second group of keys 19 2021 22 23, located on the left-hand side, serves to produce the angular movements of the barrels of slight amplitude or those corresponding to one, two, three, or four generatrices. The third group of keys 24 25 26 27 serves to produce the angular movements of greater amplitude or those corresponding to one-quarter, one-half, or threequarters of a revolution of the barrels.
The surface of a barrel l may be considered as being composed of several cylindrical segments 28 29 30 3l or letter-fields,- as indicated in a separate view on the drawings ad- IOO jacent to Fig. 3, each of which letter-fields or type groups corresponds, respectively, to one of the keys 24 to 27 of the third above-de'- scribed group. When one of the said keys- 26,forexan1ple-is pressed, the corresponding letter-field 30 is brought to the lower part of the barrel opposite the printing-roller. two other groups of keys are for the purpose of determining the position of a character of the said letter-field 30 in such a manner that it comes exactly above the printing-point. This result is obtained by pressing one of the keys 19 to 23, which causes the barrel to rotate to a slight extent, which is inferior to the width of the field, and by pressing-simultaneously one of the keys 14 to 18, which causes the bar-rel to move lengthwise.
The keys 14 to 18 are carried by key-levers 32, oscillating on a spindle 33, Fig. 3, and the forward ends of which are located under a frame 34, so mounted as to be free to oscillate around a horizontal spindle 35. On one of the sides of the said frame is fixed a lever 36, the end of which engages in the groove of a collar 37, fixedly attached to the spindle 7, so that the latter can be shifted lengthwise a longer or shorter distance, according to the more or less inclined position taken by the frame 34,.
To modify the inclination of the frame 34, each of the key-'levers 32 is provided with two upward projections 38 and 39, located under the front and back sides of the frame 34, the heights of the said projections being so regulated that when the tive levers 32, corresponding to the tive keys 14 to 18, are operated sucdinal play.
inclinations, to which correspond five differeut longitudinal positions of the spindle 7 and of the barrels 1 and 2.
The keys 24 to 27 are mounted on key-levers 40, oscillating around a spindle 41 and acting in a similar manner on a frame 42, movable around a spindle 43. The said keylevers 40 are provided with the upward projections 44 and 45, acting on two opposite sides of the frame 42 and serving to give the latter as many dierent inclinations as there are levers 40. On one of the sides of the frame 42 is xed a lever 46, connected by a pitman 47 to a carriage 48, sliding on a guide-bar 49, parallel to the spindle 7. The said carriage 48 forms a sort of cage for the sleeve 11, on which cage the sleeve has but small longitu- It will be understood that the operation of each` key 24 to 27 gives a particular inclination to the frame 42, and consequently a particular position to the carriage The levers 50, pivoted on a spindle or rod 51, is connected by a pitman 52 to the crank-pin 53 of a crank 54, turning around a fixed spindle 55, Fig. 8. To the said crank-pin is also pivoted a pitman 56 of the same length as the pitman 54.
On a fixed spindle 57 are pivoted five elbowlevers 58, connected by pitnnen 59 to the corresponding pitmen 56, and provided each with projections 60 and 6l, located, respectively, under the front and back sides of a frame 62, oscillating around a spindle 63. rlhe heights of the projections 60 and 61 are so regulated that the frame 62 will be brought into five different positions when the tive keys 19 to 23 are operated successively. To the said frame'62 is fixed a lever 64, which is connected by a pitman or link 65 to a carriage 66, slidable on a guide-bar 67, fixed to the main frame parallel to the spindle or rod 7. The said carriage carries forward with it the stud of a roller 68, Fig. 9, running in a guideway 91, fixed to a cross-rod 92, connecting the two bearings 8. One of the ends of the stud or spindle of the roller 68 is engaged in the screw-thread`12 of the sleeve 11. For a determined position of the carriage 66 the sleeve 11 can be turned into five different positions by the longitudinal displacement of the roller 68 into tive corresponding positions when the five keys 19 to 23 are successively operated.
Above the key-levers 50 is arranged a frame 69, oscillating on a spindle 70 and connected by a pitman or link 71 to a lever 72, integral with an oscillating cross-.bar7 3, Fig. 7, mounted on pivots 7 4. Two levers 75, integral with the said cross-bar 73, are pivoted to the vertically-sliding bars 9, so that when the frame 69 is lifted by any one of the key-leversO the cross-bar 73 oscillates and causes the rods 9, the spindle 7, and the barrels 1 and 2 to move down. A spring 76 constantly tends to draw upward the rods 9, the spindle 7, and the barrels.
For the purpose of producing successively the longitudinal displacement of the carriage 66 and the lowering of the barrels the pitman or link 71 is provided with a slideway 77, Fig. 1, whereby the lever 72 is only-operated during the last part of the upward stroke of the frame 69. On the other hand, in order that IOO IIO
the frame 62, operated by any 011e of the levers 58, shall remain in contact with the projections 60 and 61 after the first part of thg oscillation of the corresponding key-lever 50 a striking-.lug 78 is formed on each of the crank-arms 54, so as to prevent the pitman.
` side of which is located opposite the projections 81, formed on the ends of the key-levers 32. When one of the latter strikes the frame 80, the latter becomes inclined and the catch 79 releases a lever 82, integral with the crossbar 73. The latter can then be operated to produce the printing. The catch 79 and the `frame 8O are then brought back into their initial position by a spring 83, when the pressure ceases on the key-lever.
To lock the carriage 48 each time it is brought into a fresh position, I may arrange on the spindle 43 a frame 84, one side of which is located opposite the projections 45, formed on the ends of the key-levers 40, Fig. 6. The said frame is connected by a link 86 to an oscillating piece 87, provided with a stop-iinger 88,capable of becoming engaged in anyone of the four holes 89 in the carriage 48 corresponding to the four positions which the said carriage is capable of taking. When one of the keys 24 to 27 is pressed down, the corresponding key-lever lifts the frame 84 and through the medium of the link 86 causes the piece 87 to oscillate in such a manner as to disengage the finger 88 from a hole 89. When the pressure ceases on the key, the frame 84 is brought back by a spring 90, and the finger 88 rises ready to become engaged with another hole 89.
The feed of the printing- carriages 5 and 6 and the unwinding ofan inked ribbon or the :inking of the barrels may be produced in any well-known manner each time one of the keys 14 to 18 is operated, as in the type-writing machines now in use.
The operationof the machine is as follows: Before printing a type or character the carriage 48 must be brought, by means of one `of the keys 24 to 27, into the proper position to allow of the letter-field containing thedesired character being ulteriorly displaced relatively to the printing-roller by means of other keys in order to bring the desired-character exactly above the printing-point. For that purpose the keys 24 to 27 may correspond, respectively,to figures, to capital letters, to small letters, and to signs. The seg- `ments 28 to 3l of a barrel carry characters corresponding to the said keys whether the said characters be, respectively, figures, capital letters, small letters, or signs. After one of the keys 24 to 27 has been pressed down it may be released, and the carriage 48, locked by the finger 88, remains in the position into which it is brought.V When pressure is simultaneously exerted on one of the keys 14 to 18 and on one of the keys 19 to 23, the key 16, for example, being moved down with its lever 32, the frame 34, operated by the two projections 38 and 39, takes a determined inclination and remains invariably in that position so long as downward pressure is eX- erted on the key 16. The lever 36 thus displaces the spindle 7 by means of the collar 37 and brings the barrels 1 and 2 intoaposition for which the circular row of type containing the desired character will be located above the line of printing. In pressing down a second key-21, for example-the correspending key-lever displaces the crank 54, as shown in Fig. 8. The corresponding lever 58 is at rst operated by the links 56 and 59 and then remains motionless as soon as the link 56 rests against the abutment 78. In that position the lever 58 rests, through the medium of its projections GO and 61, against the frame 62 and holds the carriage 66 in a position for which the stud ofthe roller 68 has so set the sleeve 11, as well as the spindle 7 and the barrels 1 and 2, that the desired character is located exactly above the printing-point. The twenty-live characters of each letter-field can thus be brought to the printing-point by operating, two by two, the keys 14 to 18 and 19 to 23, according to twentyve different coordinations. By continuing to exert pressure on the key 21 the frame 69 is sufficiently lifted to operate the cross-bar 73 and move down the spindles 7 and 9 and the barrels to do the printing. When the keys are released, the corresponding levers move back into their initial position, but the frames 34, 42, and 62 remain free in the position into which they have previously been brought. The spindle 7 and the barrels move up 'through the action of the spring 76.
As will be seen, the mechanism for operating the barrels comprises three similar parts composed of a small number of elements or members and easily constructed. The arrangement of the key-levers in combination with the frames has the particular advantage of preventing any coming together, wedging, or injury of the parts when two or more keys belonging to the same group are operated simultaneously. Finally,the application of special mechanism to shift the letter-field presented to the action of coordination with two other mechanisms has the Very great advantage of supplying a great number of characters, while greatly reducing at the same time the number of keys.
