SPECIFICATION forming part of Letters Patent No. 501,220, dated July 11, 1893. Application filed May 3, 1892. Serial No. 431,731. (No model.) Patented in England March 4, 1892. No. 4,283-
To ctZZ whom it may concern.-
Be it known that we, VIcToR VAN DER MYNSBRUGGE, a subject of the King of Belgium, and MARY VAN DER MYNSBRUGGE, a subject of the Queen of England, residents of the city, county, and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, (for which we have obtained British Patent No.4,283 ;of March 4, 1892,) of which the following is a specification.
This invention relates to improvements in type-writers; and the object of our invention is to provide a typewriting machine which is simple in construction, readily adjusted and not apt to get out of order.
The invention consists in a typewriting machine constructed with the usual type-levers and key-levers, a rocking-bar resting on the key-levers and fixed on the rocking-shaft, which rocking-bar has projecting arms carrying pawls at their ends, the pawl on the upper arm serving to operate either one of the ratchet-wheels on two ribbon spools on which the inking-ribbon is wound, said ribbon passing through a triangular head on the end of a pivoted ribbon-guiding arm, which ribbon guiding arm also has an aligning-device composed of two pins, of which one is fixed on the arm and the other on a pivoted and adjustable piece on the arm. The pawl on the other arm engages a rack fixed on a carrier, that is mounted to move in the direction of the length of the cylinder, and said carrier supports a cylinder-carriage, which cylindercarriage is mounted to move on the carrier transversely to the direction of the length of the impression-cylinder, so as to permit of shifting the cylinder to receive impressions of the type for capitals, small letters and nu- 1n erals.
the capitals and numerals.

Fig. 5 is an enlarged detail end-view of the mechanism. for shifting the roller transversely to its longitudinal axis for Fig. 6 is a vertical longitudinal sectional view on the line 6 6, Fig. 1, showing the arrangement of the spring, bell and adjustingbar. Fig. 7 is a perspective-view of the carrier and carriage, parts being omitted. Fig. 8 is a detail perspective-view ofthe ribbon-guide and alignment-device. Fig. 9 is a detail-view of the type-end of one of the type-bars, and Fig. 10 is a detail-view of one of the supportingstandards on which the type-levers are pivoted.
Similar letters of reference indicate corresponding parts.
The base-plate A is provided with two segmental standards A A on which the typelevers B, shown by singles lines in Fig. 1, are mounted pivotally.' The standards A A are provided in their upper edges with a series of notches a, the bottoms of which are provided with knife-edges a, on which the lovers rest. There are three groups of key-levers, of which two groups are mounted on the front standard A and the third group on therear standard A. In order to permit the key-levers mounted on the rear-standard A to pass, the front standard is provided with deeper notches a at regular intervals, as shown in Fig. 10. The key-levers are provided in their front-ends with upward projections of greater or less length, and on the ends of said lovers the finger-plates or buttons B are arranged, said buttons being preferably arranged in three rows of different elevations. The several type-levers C are pivoted at their lower ends on a curved bar 0, and each type-lever isconnected by a rod 0 with a corresponding key-lever B. The inner endof each keylever is connected by a spring C with the base-plate A for the purpose of pulling the inner end of the key-lever downward and holding the type-lever G in a vertical position when at rest, as shown in Fig. 2. The inner end of each key-lever B rests against the bottom edge of a curved bar D secured at its] ends to arms D of a rocking-shaft D mounted on suitable pillars D, which rocking-shaft is provided with an arm D projecting toward the front, and with a downwardly-projecting arm D. On the lower end of the arm D a double pawl D is provided, that can engage the teeth on the upper edge of the rack E fastened to the front of the carrier that will be described hereinafter. To the front forked end of the arm D a laterally swinging link E is pivoted to swing laterally and to said link a pawl E is pivoted, that can engagethe two ratchet-wheels F F connected with two ribbon-spools F F, which ribbon spools are mounted on a pivot F passed through the lower end of a square rod F passing through an aperture F of an arm G projecting toward the rear from the curved bar O, and on the top of said arm G a latch G is pivoted that enters a notch in the upper end of the square rod F and holds the same in place. On the free end of the arm G an arm II is pivoted which is provided on its free end with atriangular open head H. The ribbon b has its ends wound on the two spools F and is passed from said spools over pins G projecting from the sides of the arm G at the free end of the same, and 'is then passed under the arm H through and around the triangular head H in the manner shown in Fig. 8. That part of the ribbon b that is used for making the impression at the time is at the side of the arm H. The arm H is provided with a lateral projection I, from which a pin I projects upward. A curved arm I is pivoted to the top of the arm H and carries at its free end a pin 1 which is adjacent to the pin I and separated from the same a distance equal to the width between the two notches d d in the sides of the type head J, Fig. 9., These two pins 1 I serve to insure alignment as the type head in making the impression 1 must be in such position that the pins 1 I are in the two opposite notches d d, and as each type head must take the same position, a true alignment is obtained.
In case the,
type-head becomes worn, or any other parts 3 of the machine'are not in perfect condition, 2
the arm I can be adjusted so as to bring the pins 1 1 the proper distance from each other, to insure the proper alignment.
The arm H i can be lifted as shown in dotted lines in Fig. 2, in case the writing is to be examined. The cylinder K is mounted in two end standards 1 K projecting upward from a bar K Said bar K is secured to two curved bars L that J are mounted pivotally at their upper rear ends on a rod L supported in the upper ends of 4 the standards L that are mounted to slide on a shaft L pivoted to rock in the sides of the machine-casin g. Said curved bars L form the carriage of the machine. Track-bars M are mounted loosely on the shaft L adjacent to the bars L and project to the front and form the carrier of the machine, and it is to the front of these bars M that the rack E previously described is attached, and which rack connects the front ends of said bars M to complete the carrier. Each bar M is provided with a notch carrying a roller 9 that runs 011 the track g projecting upward from the baseplate.
At the free end of each curved bar L a roller M is mounted on the rod Q and can run on the corresponding bar M. On the front end of each curved bar L an arm M is pivoted on a rod Q passed through the front-ends of the curved bars L and is drawn by a spring M attached to said arm and to a standard K toward the cylinder K, and each arm M is provided at its upper end with a roller M. Endless rubber bands 0 are passed around the rollers M around similar rollers M on the rod Q adjacent to the rollers M,on and around a loose rod M in the standards L as shown in Fig. 2, so that the said bands rest against the lower part of the impression-cylinder K. The scale-bar O is secured to the tops of the said arms M and its inner edge is thus held against the impression-cylinder. The entire carrier and carriage, composed of the bars M and L, rod Q, rack E and arms M can thus slide across the machine on the rod L, shaft L and track g, in the direction of the length of the cylinder and the bars L and K which directly support the impression-cylinder and are mounted on the upper rod L can slide in a direction transversely to the length of the cylinder, that is, from front to rear, so as to permit the shifting of the impression cylinder to receive the impressions of the three different types on the type-heads. The carrier with the rack E, mounted on the shaft L does not change position when the cylinder is shifted transversely to its length.
For the purpose of causing the shifting of the impression-cylinder, the two left hand key-levers are used. As shown in Fig. 5, said levers, the inner ends of which will be designated by h h, are of different lengths. The lever It can act on the front end of an arm N fixed on the shaft L on which the standards L are fixed. The rear-end of the arm N can strike against an adjustable stop-screw N screwed through the toppiece N on the back of the machine-casing or frame, and the rearend of said arm N is pulled upward against said stop by a spiral spring N". A verticallysliding plate P, having a projection P toward the rear at its top and an angle-piece P toward the front at its bottom, is arranged on the side of the standard L and the inner end of the key-lever h is below said angle-piece P Ordinarily, the impression-cylinder remains in such position that the front type on the type-head makes the impression.
When it is desired to print capitals, the impressionecylinder must be shifted toward the rear a short distance, and when it is intended to print numerals it must be shifted toward the rear a greater distance. To shift theimpression-cylinder for capitals, the left hand lever h is depressed, whereby the slidingplate P is lifted and then the arm N is swung upward at its front end, causing the standards L and the rod L to swing in the direction of the arrow 00, Fig. 5, until the rear edge of the raised sliding plate P strikes the stop-screw 1 screwed into thetop-piece N -on the rear of the machine, thereby stopping the cylinder after it has been moved to the rear a short distance. As soon as said lever 71. is released, the sliding-piece P drops and the spring N swings the standards L and rod L to the front again and the cylinder is moved correspondingly, as the curved bars L on which the roller is supported, are pivotally mounted on said rod'L' and must swing with L 'is swung in the direction of the arrow at until it strikes against the stop-screw P and the impression-cylinder is moved to the rear a greater distance.
For the purpose of line spacing the paper, an elbow-lever Q is pivoted on the end of the rod Q of the carriage, which rod carries the above-mentioned rollers M and is surrounded bya spring Q pressing the upperend of said elbow-lever toward the impression-cylinder K. A weighted pawl O pivoted to the upper end of the elbow-lever Q is in engagement with the ratchet-wheel Q on the end of the cylinder K. An elbow-lever R is pivoted on lugs R of an extension of the bar K and its inner end rests on the lower shank of the elbow-lever Q, so that when the outer end of said elbow-leverRis pressed in the direction of the arrow X the pawl Q is moved to turn the impression-cylinder. In the back of the casing the longitudinal slot S is provided through which the stem S of a bell Z passes, said stem being provided with a thumb-nut S The bell can be adjusted in said slot to ring the alarm for lines of varying lengths and locked in place by the thumb nut. Said bell is provided with an arm S from which another arm S hangs that is provided with a hammer-S To the lower end of the hammer S the beveled dog or pawl S is pivoted. A cord T is secured at one end to a spring in the casing T and the other end is fastened to a pin T projecting from the back of the carrier. A rack U is pivoted to swing on its longitudinal axis in the casing and can be turned by means of a button'U on one side of the casing. A spring U surrounding the reduced portion at one end of the rack serves to hold said rack in vertical position. An adjustable stop-dog V rests freely on said rack in the path of the pin T and can be adjusted as may be desired.
X is the spacing-key.
The operation is as followsz-The bell and the stop V may be adjusted as necessary. As the carriage moves in the direction of the arrow X Fig. 6, the pin T passes under the dog S of the bell without actuating the hammer and finally the pin strikesthe stopV and stops the carrier and carriage. The paper is then shifted by means of the lever B. As the carrier and carriage move in the inverse. direction of the arrow X Fig. 6, and before they arrive at the end of the line, the pin T strikes the dog S of the bell and swings the arm S from the bell. When the pin passes said dog, the arm S swings toward the bell and the hammer S strikes the bell. When the carriage moves in the direction of the arrow X Fig. 6 and is not to be stopped, until it reaches the side of the casing, that is, when the full line is to be written, the rack U is turned down, so that the stop V will be out of the way of the pin T and the latter cannot strike against the same. Every time a keylever is struck, the bar D is swung upward and swings the arm D carrying the pawl D whereby the impression cylinder K is released the distance of onetooth of the rack and can be drawn in the opposite direction of the arrow X by the motor-spring. As the arm D swings, the arm D also swings, causing the pawl E to rotate the ratchet-wheel of that ribbon-spool with which it is engaged in the direction of the arrow X Fig. 2, the other spool being loose. The ribbon is thus wound from one and wound upon the other spool. When the direction of the ribbon is to be reversed, all that is necessary, is to swing the link E in such a position that its pawl F. engages the other ratchet-wheel F.
