HENRY H. UNZ, OF NEW YORK, N. Y., ASSIGNOR TO THE NATIONAL TYPE IVRITER COMPANY, OF PENNSYLVANIA.
TYPE-WRITING MACHINE.
SPECIFICATION forming part of Letters Patent No. 472,836, dated April 12, 1892.
Application filed March 11, 1886. Serial No. 194,795. (No model.) I
To all whom it may concern:
Be it known that I, HENRY II. UNZ, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in lype-IVriting Machines, of which the following is a specification.
The object of my invention is to simplify the type-writer as regardsthe method of constructing and operating the same, and at the same time to extend the limits of its capabilities and make it cover a wider range of usefulness than heretofore.
In the accompanying drawings, Figure 1 is a vertical sectional view on a line from front to rear of a machine, showing my improvements. Fig. 2 is a plan view of the lower part of a machine, showing my improvements in the type-barand. key-lever movements. Fig. 3 is an enlarged detail. Fig. 4 is a sectional view showing details.
The same letters refer to the same parts throughout.
In this machine the number of key-levers may be confined to a single alphabet and space; but the number of the type may include capitals, 1ower-case, numerals, and punctuation-marks ad libitum, and the method of causing any particular key-lever to operate any desired typeis one of theleading features of my invention.
In my machine the type-bars Aare hung in the usual manner in the brackets a; but the brackets to, instead of being secured, as usual, to the stationary frame of the machine, are secured to the annulus, ring, or segment B, which is fitted in and guided by the frame 0 in such a manner that it may be revolved around a center line that coincides with the position of impact of the type upon the paper or the common center to which the type swing when in use.
The type-bars A are not connected, as usual, to their kev-levers, but have one or more projections a which engage with corresponding indentations d in the connection (1* of the key-lever D. The connections (1 are so guided and steadied by the frame 0 that they have a fair rectilinear movement, and are positively-actin g connections, moving the type-bars both to and from the paper, while the indentations (l are so adjusted in relation to the type-bars A as to present a uniform but not continuous groove around them when at rest, as indicated by the dotted line d ,Fig. 1. It is obvious thatin operating akey-lever in the usual manner it will actuate whatever type may at the time stand engaged with it, and to shift the work from lower-case to capitals, it is only necessary to revolve the ring B, and with it the whole type system, sufficiently to throw the lower-case types between the key-levers, as shown at a, Fig. 2, and at the same time to bring the capitals into engagement with their key-levers, as shown at a or, if standingin this position, the reverse of the above-described movement will throw the capitals out of and the lower-case type into engagement with the type-levers, while a similar movement of a dilferent degree or distance may throw the letter-type all out of gear and bring the numerals or punctuationmarks to engage with the type-levers in place thereof, and the same will hold true whatever form of key-lever or whatever the relative positions of power, fulcrum, and weight of such lever may be preferred. This revolution of the type-ring B may be performed by various means, as bevel-gear, cams, ratchet, or a simple handle. A convenient and simple method for common use is shown.
The ring B is provided with a projection or indentation Z), which engages with a lever E, by actuating which the ring B can be revolved, as desired, while a spring 6 is provided to re turn the ring B to its normal position, and retain it there whenever the pressure upon E (or c, Fig. 4) is removed. The upper spring 6 Fig. 4, is intended as a safeguard. It presses on a latch 0 which is raised on inclines e in the annulus B if the latter is turned either to the right or left, and in either case has the tendency to return the ring B to a central position. A gage-ring b is provided upon the ring B, which acts asa stop, holding all of the type-bars at a uniform level when out of work, so that they may pass freely in and out of engagement with the connections d of the key-levers when the ring B is revolved, while for the same purpose the keylevers D are each provided with a spring d,
which holds the lever steadily against the fulcrum d and stop-bar 01 when not in operation, thereby bringing the connections d accurately to their proper level.
It will be seen that by revolving the typering B the machine may be adjustedto print in cipher for plain copy or to print plain the operation and revolve the ring B until type A engages with key-lever D; and the cipher-copy may be reduced to plain print by a purely mechanical operation. The variations and combinations attainable by this means are practically infinite, and the writer can Write h s letter partly plain or one'or. LVIIOI'Q words in cipher or every word in adifferent cipher by simply revolving the type-ring B by some p reconcerted rule.
Having thus described the nature and uses of my invention, what I claim, and desire to secure by Letters Patent, is
1. In a type-Writer, the combination of the type-bars A and rotatable annulus B, carrying gage-ring b, substantially as and for the purposes herein shown and set forth.
2. In a type-writer, the combination of the key-lever D, fulcrum d spring 01, and typebars with the guided and positively-acting connection 61, substantially as and for the purposes herein shown and set forth.
3. In a type-writer, the combination of the rotatable annulus '13, carrying the type-bars, with the spring e, which returns and retains it in its normal position, substantially as and for the purposes herein shownand described.
4. In a type-writing machine, the swinging type-bar A and revolving annulus B, in combination with the key-leverD and bifurcated arm d adapted to slide. substantially as and for the purposes herein shown and set forth.
Signed at New York, in' the county of New York and State of New York, this 10th day of March, A. D. 1886.
