JOSEPH HALL, OF MARSKE, NEAR RICHMOND, COUNTY OF YORK, ENGLAND.
TYPE-WRITER.
SPECIFICATION forming part of Letters Patent No. 425,876, dated April 15, 1890. Application filed October 1, 1889. Serial No. 325,733. (No model.) Patented in England March 4, 1889, No. 3,788.
To @ZZ whom it may concern,.-
Be it known that I, JOSEPH HALL, a subject of the Queen of Great Britain, residing at Marske, near Richmond, in the county of York, England, have invented a new and useful Improvement in Typc-lVriters, (for which I have applied for Letters Patent in Great Britain and Ireland, and obtained provisional protection thereon the 4th day of March, A. D. 1889, No. 3,7S8,) of which the following is a specilication.
My invention relates to improvements in dials for type-writers, on which letters, figures, or other characters corresponding with those on the type-wheel are marked along the edge of a spiral groove or snail cut in' the dial; and the objects of my improvements are, first, to provide a dial in which the pointer is operated in a spiral groove or snail by the type-wheel, and, second, to afford facilities for the proper adjustment of the pointer to any required' letter or character. I attain these obj ects by mechanism illustrated in the accompanying drawings, in Which- Figure l is a plan looking at the top of dial; Fig.l 2, a sectional elevation of dial and means for communicating motion to the pointer. Fig. 2 is a detail view of the toothed bar for operating the type-wheel. Figs. 8 to G are details of parts.
Similar letters refer to similar parts th roughout the several views. Y
In the drawings I have shown the dial and parts connected therewith applied to and operated by a type-wheel of well-known constru ction; but I Would have it understood that it may be arranged to work with any revolving type-wheel.
A is the type-wheel, and B the fixed spindle upon which the Wheel A revolves.
C and D are respectively the ends of the frame supporting the typewheel; E, the pinion fixed to the tube orboss of the typewheel, and F the rack for operating the type-wheel. The type-wheel may, however,be mounted and operated in any suitable way, these features constituting no part of my present invention.
To the stay or frame D is attached in any suitable manner a bracket G, or, when preferred, it may form a part of the frame. Above the bracket is mounted a thin metal or other plate, forming the dial H, in which is cut, cast, or stamped a spiral groove, recess, or snail 7L, around the edges of which are fixed, stamped, or engraved letters, figures, or other characters corresponding with those on the type-wheel.
In the drawings I have shown the dial marked with Roman capital letters, figures, and stops; but when preferred small letters and any other required printed character may be marked or placed thereon. In practice the letters, figures, or other characters are so arranged around the edge of the groove h that when the pointer is indicating a given letter or character on the dial the corresponding letter or character on the typewh eel is simultaneously brought into position for printing purposes. By this arrangement a large number of letters, numbers, dac., may be placed on the dial and arranged far enough apart to prevent confusion and be readily seen. Immediately below the dial H is a lever or arm I, provided -with a slot-hole t', in which a block J slides freely. The arm I is mounted on a vertical shaft or spindle K, carried in bearings on the bracket G. The block J is armed with a pin j, which is made to pass up into the spiral'groove h, and is then bent over to form a pointer as well as aiding in retaining the block J in position with the dial and arm. At the opposite end of the vertical shaft K to which the arm is mounted is fixed a bevelwheel L, which gears with a second wheel L', cast with or fixed to the type-wheel A. Above the bevel-wheel L is mounted a milled headed boss M for enabling the operator to readily set or adjust the pointer on the dial without the aid of the rack F.
The headed boss M is rigidly connected with the shaft K, and by turning it in one direction or the other the shaft may be turned to rotate the pinion L, and by means of the pinion L move the type-wheel A. The pointer, which is connected with the shaft K, will of course be correspondingly moved. -Thus the shaft-wheel and the pointer may be brought to any desired position by hand without operating the rack F.
The action of a machine to which these improvements are applied is as follows: The paper having been fed through suitable feed- IOO ing devices to the type-wheelA, the latter is rotated either by moving the rack F or by means of the milled headed boss M, whereby motion is conveyed from the type-wheel A through gearing L L' to the shaft K (or from shaft K to the type-Wheel) and thence to the arm I. The toothed bar or rack F is `arranged horizontally and guided in the frame C, in which it is free to slide and gears with the pinion E on the shaft to which the type-wheel is secured. By moving the rack back and forth the type-wheel may be revolved, and the pointer correspondingly revolved by means of the gearing above set forth. When the arm I is caused to rotate, the pin j (which forms the pointer) is carried round with it and works (by means of its connection with the block J, which is free to slide inward or outward in slot-hole t', according to the way in which the arm I and pin j are rotated) in the spiral groove or snail h until the desired letter, character, or other figure is reached, when the corresponding letter or character on the typewhcel will by means of the shaft K and gearing L L have been brought into position for printing purposes.
Iam aware that prior to my invention type writers with dials having a pointer revolving on a pin working in axial bearings have been made. I therefore do not claim such a combination broadly.
In Letters Patent No. 421,702, granted'to lne February 18, 1890, I have shown a typewheel similar in general construction to that herein shown and described. The type-wheel in said patent is mounted on a shaft pro'- vided with a pinion which is operated by a toothed bar or rack.
What I do claim as my invention, and desire to secure by Letters Patent, is
1. A type-writer dial formed of a thin plate having a spiral groove cut therein, around which letters or other characters are arranged spirally, in combination with a pointer traversin g the spiral groove, and a printing-Wheel with which the pointer is geared, substantially as described.
2. The combination of a dial-plate Il, having a spiral groove 7L formed therein, around the edge of which letters or similar characters are arranged, 'a rotating arm I, a sliding block carried thereby, a pointer j on the block traversing the spiral groove, a printing-wheel, and gearing between the printing-wheel and the rotating arm.
3. In a type-Writer dial, the combination of a dial-plate I-I, with its spiral groove h formed therein, slotted arm I, block J, pointerj, spindle K, boss M, gearing L L', and bracket G, all substantially as herein set forth and illustrated.
4. In a type-writer, the combination of a rotating type-wheel A with a dial-plate Il, having a spiral groove formed therein, around which letters or other printing-charactersare marked corresponding'wit-h those on the type- Wheel, slotted arm I, block J, pointer j, spindle K, gearing L L', boss M, and bracket G, all substantially as herein set forth.
5. In a type-writer, the combination of typewheel A, spindle B, frames C and D, pinion E, rack F, bracket Gr, 4dial-plate II, with spiral groove h 'formed therein, slotted arm I, block J, pointer j, spindle K, gearing L L', and boss M, all substantially as herein set forth and illustrated.
In testimony whereof I have hereunto signed my name to this specification in presence of two subscribing witnesses.
