ANDREV STEIGER, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TOVYOST WRITING MACHINE COMPANY, OF ILION, NEV YORK, A CORPORATION OF NEW YORK.

TYPE-WRl'l'lNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 747 ,259, dated December 15, 1903- Application led April 8, 1901. Serial. No. 54,894. (llo model.)

To @ZZ wiz/m, t may concern:

Be it known that I, ANDREW W. STEIGER, a citizenof the United States, and a resident of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

This application relates to the type actions to of writing-machines.

Generally the key-lever system is of greater width than the type-bar system, laterally-inclined connecting-rods being used in some cases between the side key-levers and typebars, and the levers of other machines being crowded together so as to bring them within a space as nearly equal as possible to the width of the type-bar system.

The main object of my invention is to avoid zo the necessity of unduly crowding the key-levers together or of using inclined connections at the sides of the machine, which have a more or less cramping effect'upon the keylevers and produce uneven wear on the typebar pivots.

To these and other ends my invention consists in certain combinations of devices, features of construction, and arrangements of parts, all as will be hereinafter fully set forth,

3o and particularly pointed out in the concluding claims.

In the accompanying drawings, in which my improvements are shown in connection with the type system of a Yost writing-machine, Figure 1 is a sectional elevation taken longitudinally of the machine. Fig. 2 is a section taken transversely of the machine and about centrally of the type system. Figsl 3 and 4t are side and front elevations of a key- 4o lever hanger or post. Fig. 5 is a sectional detail of ajoint. Fig. 6 isafragmentary sectional plan of a portion of the key-levers and their type-bar connections. Fig. 7 is a diagrammatic plan of the key-lever and typebar system.4 Fig. 8 is a plan of a blank used in forming a connecting-rod. Fig. 9 is an edge view of a complete connecting-rod.

In the several views portions of the machine are omitted or broken away to more 5o clearly disclose the invention, and similar parts are designated by similar numerals of reference.

Each of the type-bars comprises arms 1 and 2 and a link 3, pivoted upon the free ends of said arms and having at its free end a type 4, which normally contacts with an ink-pad- 5, whence it may be swung upon said arms to make an impression uponthe under side of the platen 6, as illustrated at Fig. 2. The arms 1 are pivotally supported at their inner disk-like ends upon a hollow annulus 7,whicl1 is fixed upon a bracket 8. The arms 2 are pivoted at their outer ends upon a fnlcrumwire 9 and work in radial slots 10 cut in a ring 11. Said arms 2 are connected by rods 12 to key-levers 13 of the first order,` said levers being pivoted between their ends upon pins 11, projecting laterally from hangers or posts 15, which are rivetedat 16 upon the under side of a horizontal plate 17, which forms a portion of the base of the machine, springkeepers 18 being riveted at 19 tothe sides of said hangers to prevent accidental displacement of the levers from their fulcrum-pins, while enabling the detachment of any lever when desired. Each lever is provided with a wire returning-spring 20 and a linger-key 21, the latter having a hollow stem 22, which works in a perforated guide-bar 23 and a guide-hole 24, formed in said plate 17. Said stem is connected to the lever by an attaching-piece 25, which is forked to bestride the forward end of the key-lever, and is provided with a pin 26 to engage a short horizontal slot 27, formed in the forward end of the key-lever. The arms of the fork are made separable for permitting detachment of the lever, and the attaching-piece is formed with an upwardly-extending stem 28 for insertion into the open lower portion of the tubular keystem 22. Y

The upper end of the connecting-rod 12 is pivoted at 29 to the type-bar arm 2, and the lower end thereof is connected by an attaching-piece 25 to the rear end of the key-lever, the latter being horizontally slotted at 30.

To the lower portion of. each rod 12 is pivoted at 31 the outer end of one of a series of horizontal links 32, the inner disk-like ends 33 whereof are arranged in an annular bear- IOO ing-groove of C cross-section formed by centrally arranged upper and lower grooved plates 34 and 35, which are clamped together andv held upon a boss 36 by a screw 37, said boss being cast or xed upon the base-plate 17. The links 32 are of equallength and radiate from the bearing-ring 34 in directions corresponding with the radial positions of their associated type-bars. The outer ends 31 of the forwardly and rearwardly extendingv links 32 at the middle of the machine lie almost directly over the rear ends of the keylevers with which they are associated, their connecting-rods extending about vertically from the key-levers to the type-arms, as illustrated at Fig. l. The width of the key-lever system being, however, greater than the diameter of the circle of vertical `connectingrods l2, the levers at the sides of the machine lie at increasing distances outside of said circle. These outlying levers are connected to the vertical rods 12 by means of lateral arms or offsets 38, extending radially outward from the latter and varying in length according to the positions of their respective levers. At its outer end each odset is formed with a down wardly-directed thimble or socket 39 for receiving the stem of an attachingpiece 25, by which said offset is connected to the key-lever. The upper end of the rod 12 is folded and bifurcated at 40 to straddle the type-bar arm 2, the tines of the fork being yielding, so as to enable the detachment of the rod from the type-bar. The shouldered rivet 3l is provided with a large head to prevent undue sway of the links 32 and 12.`

When a key is depressed, its lever is vibrated upon the fulcrum 14 and the rod 12 is thrust upwardly, thereby swinging the arm 2 and causing the type to be impressed upon theplaten or the paper thereon. The keys have substantially uniform dips, and the key-levers have substantially uniform movements at their rear ends, including those key-levers which are arranged at the sides of the machine and connected to the offsets 38. Since the rods 12 are pivoted upon the typebar arms 2 and the links 32, all parts of said rods, including the offset arms 38, have substantially uniform vertical movements, and the outlying key-levers are equally effective with those at the center of the system in operating the type-bars. It will be seen that if a link should be connected to an extreme outlying key-lever and extended diagonally upward to its type-bar without being guided at its lower end independently of the key-lever there would occur at the operation of the key a lateral thrust upon the key-lever which would cramp the same and impede its movement; but by having the link l2 positively guided by a separate device cramping action is avoided, and hence the key-levers may be placed at any desired distance from the center of the machine, the offsets 38 being correspondingly lengthened.

Upon the guiding-links 32 I arrange an antion thereof remaining at rest and having a bearing upon the opposite link 32, whereby said universalbar is enabled by acting as a lever of the second order to lift the collar 45 and rod 44, which by a nut 46 thereon lifts the inner end of a forwardly-projecting arm 47, formed upon a dog-rocker 48, which is pivoted at 49 to a bracket 50. Said rocker is provided with a returning-spring 51 and carries at its upper end both a detent-dog 52 and a feeding-dog 53, the latter being in engage ment with an escapement-wheel 54, which is connected by a pinion 55 and rack 56 to any suitable platen-carriage 57, propelled by a spring-barrel 58, to which it is connected by a strap 59. Upon said movement of the dogrocker the feeding-dog is disengaged from the escapement-wheel and the detent-dog engaged therewith, and upon the subsequent return of the type-bar and universal bar to normal position said dog-rocker vibrates in the reverse direction and permits an advance movement of the carriage in the usual manner. v

From the foregoing description it will be understood that the rods 12 at the sides of the machine with their offset portions 38 constitute angular rods or links which are connected at their ends to the arms 2 and to the levers 13 and thatthese rods comprise each horizontal and vertical arms.

Various changes may be made within the scope of the invention, some parts whereof may be used without others.
