W'ALTER J. BARRON, OF BROOKLYN, NEXV YORK.

TYPE-WRITI NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 470,172, dated March 8, 1892.

Application filed September 3, 1891. Serial No. 404,590. (No model.)

1'0 all whom it may concern.-

Be it known that I, WALTER J. BARRON, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Type-\Vriting Machines, of which the following is a specification.

My invention relates, first, to the paperfeed-ing devices, and, secondly, to the ribbonfeeding devices; and it consists in the features of construction and combinations of devices, hereinafter more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a front view of a type-writing machine embodying my improvements, the keyboard being removed to afford a viewof the construction and arrangement of the devices at the lower rear portion of the machine which form part of the ribbon-moving mechanism, and the paper-carriage being turned up to afford a view of the paper-feeding devices. Fig. 2 is a side elevation of the machine with the keyboard added and the paper-carriage down in working position, and with a portion of the frame-work at the rear of the machine broken away to show the arrangement of the ribbonfeeding devices, and with the knob or handwheel at the left-hand end of the pressureroller shaft omitted to avoid complication of the view. carriage with the pressure or feeding roller out of engagement with the platen. Fig. 4 is a face view of one of the driving-pawls of the ribbon-spool ratchet-wheel. Fig. 5 is a diagram to illustrate the movements of the ribbon and the manner in which the type strike the same. Fig. 6 is a partial front view similar to Fig. 1, but exhibiting the devices for feeding the ribbon longitudinally, as arranged to operate on the downward movement of the driving-pawlin lieu of the upward movement, as in the arrangement shown at Fig. 1.; and Fig. 7 is a diagram to show the movement of the ribbon and the manner in which the type strike the same when the ribbon is fed in accordance with the plan shown at Fig. 6. 1

In the various views the same part will be found designated by the same numeral of reference.

The machine illustrated will be recognized as that known as the Caligraph, to which Fig. 3 is a side view of the paper-,

my ribbon-feeding improvements are more especially adapted.

1 designates the frame-work of the machine 2, the type-ring; 3, the carriage guide-bar; 4, a yoke adapted to slide on said guide-bar and connected with the rear rod 5 of the papercarriage. In the side bars 6 and 7 of the paper-carriage is mounted to rotate the usual cylindrical paper-platen 8, having at one end a ratchet-wheel 9, adapted to a line-space leverand platen-check, (not shown,) and having also at the end of its axle a hand-wheel 10, by which the platen may be turned. The front rod 11 of the carriage is provided, as usual, with an anti-friction roller 12, which travels on a track or way 13, supported on pillars 14 at each end and secured in place by long vertical screws passing through the track and pillars and entering tapped holes in the typering or top plate 2. To the front side of the track or way is attached the usual machinescale 15, with which co-operatesa pointer 16, arranged centrally of the front rod of the paper-carriage. 17 is a paper-guide for the mid dle portion of the sheets, the said guide, pointer, and wheel all being mounted on a bracket 18, attached byascrew 19 to the front carriage-rod.

The rear carriage-rod near each end is provided with a bracket 20, supporting an arm 21, which is extended and curved to pass under the platen and serve as an end paperguide 22. Upon each of said arms is affixed a bracket 23 to support the shaft'or axle 24E of a pressure or feeding roller 25, which preferably is provided at each end with a knurled hand-wheel 26. Near each end of said shaft is formed or provided a cam or wedge 27 to co-operate with depending arms 28, screwed at their upper ends to the end bars of the paper-carriage. Each cam or wedge is tapered in the same direct-ion, so that when the shaft- 24. and roller 25 are moved endwise toward the left the depending arms 28 may both act on said cams or wedges to simultaneously force both ends of the shaft, and hence the pressure-roller, outwardly or away from the paper-platen, as shown at Fig. 3. The pressure-roller is made Slightly shorter than the distance between the supporting-brackets 23, in order that the endwise movement referred to may be accomplished. The bevel or taper of the wedges is such that the roller may be moved out of contact with the platen a sufficient distance to enable the paper used to be freely inserted or removed without operating or disconnecting the line-spacing devices or disconnecting the usual platen -checl and without rotating the platen. By this construction the paper may be more speedily inserted and removed. By constructing and arranging the feed-roller so that it may have an endwise movement provision is also made for feeding the paper laterally either to the right or left, so that any omitted characterin a line may be printed in its exact place and so that at the end of the line one or more extra letters may be added, if necessary or desired.

In correcting type-written matter after the sheet has once been withdrawn from the platen it is quite diflicult to so reinsert the sheet as that the blank space which is to be supplied with a character will come exactly centrally of the prii'iting-point, or, in other words, it is almost impossible to bring the line of print into exact register again with the usual scale 29 on the under side of the platen, and if this be not done the printing of the character inserted must take place nearer one letter than the other, instead of midway between the two adjacent letters of the word, which gives to the work an appearance of improper letter-spacing of the carriage and is unsightly.

In the machine illustrated at Fig. 1 it will be observed that the shaft of the pressureroller may be moved endwise about a letterspaoe distance before the depending arms 28 can act upon the cams to throw off the pressure-roller, and this mevement is provided to enable the lateral feed of the paper.

It will be understood that the pressureroller operates to hold the paperfirmly against the platen and at all times, excepting when the cams are under or in line with the depending arms 28, and hence that if the pressure-roller be moved endwise toward the left, Fig. 1, the paper will be carried with it by reason of the frictional contact of said roller with the paper. In feeding the paper laterally the pressure-roller should not be moved endwise its full distance or far enough to allow the cams to be acted upon by the depending arms 28. With each such endwise movement of the roller the paper is moved laterally a letter-space distance; but this distance may be lessened, of course, by decreasing the extent of the endwise movement of the pressure-roller, and the paper may therefore be moved laterally only very slightly, instead of a full letter-space distance, at one movement of the pressure -roller, in accordance with the exi encies of the case. If it be dea I a u sired to move the paper sldewlse a distance greater than that of a letter-space, the papermay be held by the thumb at one edge after the first endwise movement of the roller, while the roller alone is returned to its first position, and the thumb may thenbe removed and the roller moved endwise again to carry the paper still farther laterally. In this way the paper may be moved any number of letter-spaces or fractions thereof laterally by the pressure-roller within the limits of the carriage, and for this reason several additional letters or an extra word may be added to the line of printing.

By prolonging the axis of the pressure-roller and providing a finger-piece, as 26, the said roller may not only be moved endwise, but may be also rotated, which latter is a great desideratum, since by turning said roller the reinserted sheet may be fed in line-space direction to any extent without rotating the platen or actuating the usualline-spacing devices, andhence the line to be printed can be brought to register with the printing-point with great nicety and without pulling upon the paper with the hands, as usual heretofore, at the risk of tearing or soiling the sheet.

Centrally of the machine and extending from the front to the back is a rod or shaft 30, about which is coiled a carriage-driving spring 31., and at the rear end of said rod or shaft is connected an arm 32, which is connected with the paper-carriage, as in the caligraph. Beneath the key-levers 33 is a universal bar-frame 34, pivoted at 35 and provided with an arm 36,carrying a feed-dog 37, adapted to engage with the feed- racks 38 and 39 on the carriage, as usual. At the left-hand side of the machine is a ribbon-spool shaft 40, mounted in bearings4l and provided with a crank and handle 42. Upon said shaft is splined a ribbon-spool 43, which is arranged within a frame or carrier 44, adapted to slide longitudinally on said shaft and carry with it said ribbon-spool. At the right-hand side of the machine another ribbon-spool shaft 45 is mounted in bearings 46, and upon said shaft is splined a ribbon-spool 4:7 and arranged another ribbon-spool frame or carrier 48.

At the base of the machine and near the rear end is arranged a transverse rock-shaft 49, which is provided at each end, exteriorly of the side frames of the machine, with a rocker-arm 50, the upper end of which engages a ribbon-spool carrier 48. At the lefthand side of the machine the said rock-shaft is provided with a horizontal arm or extension 51, which projects rearwardly and beneath the outer arm of a lever 52, pivoted horizontally at 53 in the frame-work. The inner arm of said lever rests upon a lug or projection 54., extending laterally from the spring-actuated driving rod or shaft 30.

At the left-hand side of the'machine is a coiled spring 55, one end of which is attached to the frame-work and the other end to the left-hand rocker-arm 50. By this construction and arrangement the ribbon 56 is given a transverse or lateral movement toward the front of the machine during the travel of the carriage to the left and a. similar movement toward the rear of the machine during the ICC travel of the carriage to the right for the beginning of a new line.

At Figs. 1 and 2 the carriage is supposed to be at the extreme right and the ribbon-spools and ribbon at the end of their rearward movements.

If the machine be operated, the paper-carriage will be fed step by step toward the left of the machine under the influence of the driving-spring 31, rod 30, arm 32, and escapement devices, as usual. As the carriage travels in this direction, the lug or projection 54 moves slowly in the direction of the arrow at Fig. 1 and allows the inner arm of the lever 52 to descend, the outer arm of said lever to rise, through the upward movement of the arm 51, and the spring 55 to rock the shaft 49 and arms 50 and move the ribbon-spool carriers and ribbon spools and ribbon toward the front of the machine, The movements of the parts are all so timed that when the carriage has traveled from right to left its whole distance the ribbon is moved laterally toward the front substantially its wholewidth, and by means of the spring 55, which is expanded when the carriage is moved to the right, and

which retracts and exerts a pull when the carriagetravels to the left, and the .lug 54 moves down in the direction of the arrow. When the carriage is returned by hand to the right-hand side of the machine for the commencement of a new line, the lug or projection 54 is turned in the opposite direction and lifts the inner end of the lever 52 and throws down its outer end and causes it to depress the rearwardly-projecting horizontal arm of the rock-shaft, so as to vibrate the rocker-arm rearwardlyagainst the tension of the spring 55 and cause the ribbon-spool carriers and ribbon-spools and ribbon to move toward the rear of the machine to the position illustrated at Figs. 1 and 2. During the return of the carriage from left to right the ribbon is moved lengthwise or partially wound from one spool onto another, preferably a distance about equal to the width of a type.

At the front end of the shaft 40 is secured a ratchet-wheel 57, adapted to be acted upon by a dog or tooth 58, having a slot 59 to provide for exact adjustment and attached by a screw 60 to a vertically-arranged rod 61, attached at its lower end by a screw 62 to a forwardly-projecting rocker-arm 63, fast on the rock-shaft 49. The upper end of said rod 61 preferably projects through an elongated hole in the top plate 2, and said rod is provided with a spring 64, attached to said top plate for the purpose of keeping the driving pawl or tooth 58 in engagement with the ratchetwheel 57 when it may be desired to have said ratchet-wheel turn.

At 65 in the frame-work is pivoted a dog 66, having a depending extension 67 of sufficient weight to keep said dog in engagement with the ratchet-wheel 57 when such engagement may bedesired.

At the right-hand side of the machine the spool-shaft 45 is provided with a ratchetwheel 68, adapted to be engaged byadriving pawl or tooth 69 similar in construction to the one at the other side of the machine and mounted on a vertically-arranged rod 7 O, attached at its lower end to a rocker-arm 71 on the rock-shaft 49. The upper end of said rod 7 O is also preferably made to pass through an elongated hole in the top plate 2, and said rod is likewise provided with a spring 72, adapted to keep said pawl 69 in engagement with said ratchet-wheel 68, when desired. At 73 in the frame-work is pivoted a dog 74, adapted to engage with said ratchet-wheel 68 and provided with a depending extension 75 of greater weight than said dog, in order that the latter may stand normally in engagement with said ratchet-wheel. i

Across the machine, just back of the keyboard and mounted to turn in bearings in the frame-work, is arranged a rock-shaft 7 6, which at one end is provided with a crank 77. and which near its left-hand end is provided with a finger 78 and near its right-hand end with a finger 79. The Said fingers 78 and 79 are beveled or tapered at their ends in opposite directions to have a wedging effect, and saidfingers are provided for the purpose of alternately disengaging the pawls and dogs of the ratchet-wheels when'it maybe desired to reverse the direction of the longitudinal travel of the inking-ribbon. I 1 The operation of feeding the ribbon longitudinally is as follows: At Fig. l-the drivingpawl is shown as in engagement with the ratchet-wheel 68. As the carriage moves step by step to the left the said pawl gradually descends on account of the downward movement of the rod and rocker-arm 71; but said pawl is kept in contact with its ratchetwheel by means of the spring 72. On the return of the carriage toward the right said pawl 69, through the rise of the rocker-arm 71 and rod 70, is elevated, and by reason of itsengagement with the ratchet-wheel 68 operates to turn the ribbon-spool 47 in the direction of the arrow and wind a small portion of the ribbon upon said spool. During the descent of the pawl 69 the ribbon is not moved lengthwise and the spool 47 is held against backward rotation by reason of the engagement of the holding-dog 34 and ratchetwheel 68. WVhen the ribbon may have been thus wholly wound from the spool 43 onto the spool 47, the direction of the movement of the ribbon may be reversed by actuating the switching devices 'so that the ribbon may be again wound upon the spool 43. In order to effect this reversal of the ribbon, the shaft 76 is rocked to an extent such that the finger 79 may operate upon and move the rod 7 0 and extension of the dog 74. In thus act ing the said finger moves the rod 70, which is flexible, toward the left against the pressure of the spring 2 until the pawl'69 is carried out of the teeth of the ratchet-wheel 68 and. the depending portion of the dog 74 is vibrated sufficiently to carry said dog down out of engagement with the teeth of said ratchetwhe'el, all after the manner illustrated atthe left-hand side of Fig. 1. By the same movement of said rock-shaft '76 the finger 78 is moved down and out of contact with the extension 67 and flexible rod til, and as soon as this takes place the dog (36 rises to engagement with the ratchet-wheel 57, and the spring 6i, acting on the rod 61, operates to throw the driving-pawl 58 into engagement with said ratchet-wheel, so that thereafter said pawl may turn said ratchet-wheel and rotate the spool 43 and wind the ribbon thereupon at each upward movement of said pawl effected by the rocker-arin G2 and rod 61 when the carriage is returned to the right. The switch or rock-shaft 7G, with the fingers 7S and 79, is held in either of its two positions by a spring-detent S0, of an angular shape, to engage on either side of a pin 81 on said rockshaft.

From the above it will be seen that the ribbon is moved crosswise toward the front of the machine as the carriage travels from right to left, and is moved crosswise toward the rear and simultaneously is fed lengthwise a short distance during the return of the carriage to the rightfor the beginning of a new line. By referring to Fig. 5 these movements of the ribbon will be found illustrated. The full or continuous lines represent the movements of the ribbon toward the front of the machine, while the oblique dotted or broken lines represent the movements of the ribbon lengthwise and crosswise on the return of the carriage to the right. 7

Referring to Fig. 6, it will be observed that the ratchet-wheel has its teeth out in a direction opposite to that in which the teeth of the ratchet-wheel 68 are out, so that the drivingpawl 69 may operate to turn the ratchet-wheel and the spool and wind the ribbon on its downwarch stroke, instead of its upward stroke, as shown in Fig. 1, and where the teeth of the wheel 68 are thus constructed the teeth of the ratchet-wheel 57 should be cut to correspond, or so out that the said ratchet-wheel and spool may be turned on the downward movement of the pawl 58. If the ratchet-wheels of the machine be constructed or arranged so that the downward move ments of the driving-pawls 5S and 59 effect the rotations of the said wheels, the ribbon will have movements such as represented at Fig. '7 of the drawings, the oblique full lines representing the movements of the ribbon during the printing operation or during the travel of the carriage from right to left, and the vertical broken lines representing the rearward transverse movements of the ribbon during the return of the carriage to the right. In this arrangement the ribbon is fed crosswise toward the front and also lengthwise a short distance while the printing is taking place, and is merely fed crosswise toward the rear when the carriage is pulled back for the commencement of a new line.

By means of the cranks 42 the ribbon may be quickly wound by hand from one spool onto another when it may be desired to remove the ribbon or put on a new one or bring a ribbon of a different color into use.

The ribbon-carriers preferably extend up to about the level at which the ribbon travels horizontally across the machine, and ad j acent to each ribbon-spool carrier is arranged a shield or support 82, consisting of a plate of sheet metal attached to the top plate or typering and bent to extend inwardly over the type-bar hangers of the machine, thus shielding them from contact by the ribbon and at the same time affording a desirable support and guide for the ribbon.

I do not claim herein combining with the paper-carriage and its driving power a ribbon, a pair of ribbon-spools, and a transverse rock-shaft connected to said spools and to the driving power, as such subject-matter is claimed in an application filed by me June -19, 1891, Serial No. 396,8l0.
