TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 717,149, dated December 30, 1902.

Application filed April 4. 1901. Serial No. 54,275. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE B. WEBB, a citizen of the United Stat-es, and a resident of Westfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type-Vriting Ma-v chines, of which the following is a specification.

My invention relates to the cylindrical ro platens of type-writing machines; and its object is to enable the rotative adjustment of the platen through minute or irregular arcs independently of the line-space wheel and without the necessity of first releasing any clutch, lock, friction-gear, or the like, the mechanism being always in position to act upon the turning of a finger-wheel, soV that the operator can instantly bring a ruled line or any desired point upon the paper into regiszo ter with the printing-point or with the usual platen scale or pointer, thus facilitating the work of type-writing upon ruled paper and blank forms, as well as the correction of errors.

z5 To these main ends my invention consists in the various features of construction and combinations of devices hereinafter more fully described, and particularly pointed out in the concluding claims.

3o In the accompanying drawings, Figure 1 is a plan of a platen-frame and platen of a Remington No. 6 type-writing machine, showing my improvements as applied thereto, the platen and certain other parts being shown in section. Fig. 2 is a vertical sectional elevation taken at the line X X of Fig. 1. Eig. 3 is a perspective View of a brake used at the left-hand end ot the platen. Fig. 4 is a perspective view of a collar which cooperates 4o with said brake. Fig. 5 is a perspective view of the finger-wheel, whereby independent adjustment of the platen is effected. Fig. 6 is a perspective view of a head secured to the left-hand end of the platen. Fig. 7 is a sec- .45 tional vertical elevation of the right-hand platen-head, showing the manner of mounting the line-space wheel thereon. Fig. Sis an end elevation of the right-hand end of the platen-frame, platen, aud line-spacing mechanism, some parts being broken away and 5o others shown in section. Fig. 9 is a perspective view of the right-hand platen-head. Fig. 10 is a perspective view of the line-space wheel, showing an internal gear formed integrally therewith; and Fig. 1l is a perspec- 55 tive view of a friction cap or brake used at the right-hand end of the platen.

Throughout the views similar parts are designated by similar numerals of reference.

The platenframe comprises a front bar l, 6o rear bar 2, left-hand end bar 3, and righthand end bar 4.. The platen comprises a hollow wooden core 5 and a rubber' sheath 6. The core is provided at each end with metallic heads, whereby it is mounted upon a central shaft or axle 7, which is journaled in the end bars of the platen-frame and provided at its projecting ends with finger-wheels 8, the latter being fixed upon the shaft by set-screws 9.

The left hand platen head comprises a 7o disk 10 (see Fig. b) and an elongated hub 11, which is bored centrally to receive the shaft 7, to which it is fixed by a set-screw 12. The disk l0 is provided with countersunk perforations 13 to receive screws 14., whereby the 75 disk is secured to the end of the platen-core, and is also provided with bearings for a train of gear-wheels, as will be presently explained. The right-hand platen head comprises a disk 15 and a small hub 16, bored to receive 8o the platen-shaft 7, (see Fig. 9,) and is provided with countersunk perfor-ations 17 to receive screws 18, which secure it to the end of the platen-core.

The line-space ratchet-wheel (designated as l 19) instead of being cast integrally with the right-hand platen-head, as usual, is made separately therefrom and is provided upon its inner side with an annular recess 20, which is adapted to tit over the platen-head 15 and 9o give the line-space Wheel a support or bearing thereon. Whenever desired, the platen may be rotated without turning the 1ine-space wheel-that is to say, the platen-head may turn within the line-space wheel while the latter remains stationary.

A disk-like cap 21, of nearly equal diameter to the line-space wheel, (see Figs. 7 and 11,)

is placed upon the hub 16 against the outer side of the line-space wheel and is secured by screws 22 to the platen-head 15, thereby holding the line-space wheel upon or against the said platen-head. The cap 21 is springy, and the screws 22 are turned in sufficiently to cause considerable friction between the adjoining faces of the line-space wheel and the diskand also between the line-space wheel and the platen-head, so that relative movements cannot occur between the line-space wheel and the platen without the application of force. The tendency of the friction cap or brake 2l is to cause the platen to move with the line-space wheel when the latter is operated by the line-space lever and also to cause the platen to stop when the line-space wheel is arrested at the completion of its line-spacing movement.

The line-space lever is marked 23 and the line-space pawl 24, the latter cooperating with a fixed pin 25, as usual, to prevent overthrow of the line-space wheel and platen at the linespacing operation. As usual, a spring-check 26 is secured at one end to the platen-frame and carries at its free end a roller 27, which engages the ratchet-teeth of the line-space wheel, so as to position the latter and also prevent accidental rotation of the platen during the longitudinal movements of the platenframe. The usual pressure-roller, which cooperates with the platen to feed the paper, is

` indicated at 28, Fig. 3, and the usual platenscale at 28.

The relative movements of the platen and line-space wheel above referred to are produced by toothed gearing, inclusive of an internal gear 29, which is formed integrally with the line-space wheel, Fig. 10. In other words, the line-space wheel is in the form of a ring having external ratchet-teeth and internal gear-teeth.

The fine adjustment'of the platen and the paper thereon is eected by a third fingerwheel 30, which is of shell or cup like construction (see Fig. 5) and is loosely mounted within the platen-frame upon the hub 11 at the left-hand end of the platen, the open side of the cup or shell being placed next to the platen-head 10.l The finger-wheel 30 is pressed against the platen-head by a'yielding frictionwasher 3l, which is placed upon the hub 1l between the linger-Wheel and acollar 32, secured upon the hub by a set-screw 33. Said friction-washer acts as a brake to hold the tinger-wheel against accidental independent rotation.

Fixed to the wheel 30, upon the inner part thereof, is a centrally-arranged pinion 34, which meshes with a pinion 35, that is carried upon the platen-head lO, said pinion 35 also carrying a smaller pinion 36, rigid therewith. The pinions 35 and 36 may be mounted for rotation in any suitable way-as, for instance, upon a pivot or stud 37, projecting outwardly from the platen-head and secured thereto by a nut 38.

The smaller pinion 36 meshes with a larger toothed wheel or pinion 39,which is fixed upon the left-hand end of ashaft 40, the latter eX- tending for the entire length of the platen and being mounted at its ends at 41 and 42 in the left-hand and right-hand platen-heads,respectively, the left-hand end of the shaft being recessed to receive the pinion 39 and the latter being held in place thereon by a nut 43. Upon the right-hand end of the shaft is fixed a smaller pinion 44, which meshes with the said internal gear 29, Figs. l and 8.

In operation the finger-wheel 30 is rotated, and its movement is transmitted, through the described train of gearing 34, 35, 36, and 39, to the shaft 40, which is thus caused to rotate slowly vin its bearings 41 and 42. As will be understood by reference to Fig. 8, the linespace wheel at this time is held stationary by the check-roller 27, and hence the pinion 44 upon the slowly-revolving shaft 40, being unable to force the line-space wheel to revolve, is itself caused to travel or run around the internal gear 29, which may be regarded as a temporarily-fixed circular rack. Since the gears 35, 36, and 39 and shaft 40 and pinion 44 are all mounted on the platen or are parts thereof, it follows that the platen turns with the pinion 44 as the latter creeps around the temporarily-stationary gear-Wheel 29. If the combined ratchet-and-gear ring were not held ,by the spring-detent 27, the turning of the Wheel 30 would cause said ratchet-and-gear ring to revolve; but inasmuch as the latter cannot turn it will be seen that the platen must turn, and hence in this way the platen may be adjusted through any desired arc without rotating the ratchet-wheel and by simply turning the thumb-wheel 30 in either direction. i

The iinger-wheel 30 may be rotated in reverse directions to cause reverse adjustments of the platen, it being understood, however, that the rotative adjustment of the platen is always in a direction opposite to the movement of said inger-wheel. For instance, if the finger-wheel and pinion 34 at Fig. 2 are turned to the right,v as indicated by the arrow, the pinions 35 and 36 turn to the left and the pinion 39 and shaft 40 turn to the right, thereby through the pinion 44, which is in engagement with the stationary rack 29, causing the platen to be worked around to the left, or in a direction, opposite to the arrow at Fig. 2.

During the operation of the line-spacing mechanism the line-space wheel and platen rotate together, as if rigidly secured to each other, since the described train of gearing, taken together with the brakes 2l and 31, prevents accidental overthrow or other irregular movement of the platen relatively to the line-space wheel, the brake 31 also prevent- IOO ing accidental movement of the inger-wheel 30 relatively to the platen. Thus it will be seen that the platen may be rotated through one or more equal intervals, either by the line-space lever 23 or by one of the fingerwheels 8, and that at any time the platen may be adjusted through-a less or greaterinterval by rotating the finger-wheel 30, and also that after such an adjustment the linespace wheel and platen rotate together in their new relation in the same manner as before.

It will be seen that the wheel 30 is rotatable relatively to the platen and at a greater angular speed. The wheel, may be rotated any desired number of times to secure a singlerotation of the platen by providing suitable gearing between said wheel 30 and the line-space wheel.

The mechanism is always in readiness for effecting instant adjustment ot` the platen through any desired are without rst manipulating a lock, clutch, or the like, it being necessary simply to turn the finger-piece or wheel 30, and after such adjustment is effected it is unnecessary to restore any lock, clutch, or the like to original position.

It will be seen that the three finger-wheels S, 8, and 30 are arranged concentrically with the platen. Either of the wheels 8 8 may rotate the platen and line-space wheel simultaneously, whereas the wheel 30 is rotatable relatively to the platen and to the line-space wheel. Said wheel 30 may eiicect the operation in either direction of the adjusting gears or devices by which the platen is connected to the line-space Wheel. When the platen is rotated by the wheel 30 the main feed-roller 28 rotates also, so as to carry the paper around the platen.

The wheels in the described chain of gearing have parallel axes and most of them are confined within the cup-like tinger-wheel 30, so that they are readily accessible, although not exposed. The brake 21 is arranged so as to act between the platen and the line-space wheel, and the finger-wheel 30 rotates the platen relatively to the line-space wheel without releasing said brake and against the opposition thereof, but without overcoming the opposition of the detent or check-spring 26 27, the said wheel 30 being incapable of turning the line-space wheel by reason of the opposition of said check-spring. The platen is never disconnected from the line-space wheel, as is generally the case in prior constructions, although the platen may be turned independently of the line-space wheel and also with it, if desired.

The wheel 30 may be otherwise constructed and arranged and many other changes may be made in the connecting devices between said wheel and the line-space wheel and in other details of construction and arrangement, and parts substantiallydifterent from those herein shown may be used without departing from the scope of my invention, the gist of which resides in adjusting the platen by means of a finger-wheel without disconnectin g the platen from the line-spacewheel. Where a wheel is claimed, it is intended to coveranyrotatory finger-piece the equivalent of a wheel.
