TYPE-'WRITING MACHINE.

SPECI TATION forming part of Letters Patent N o. 713,68 5, dated November 18, 1902.

,Application filed April 12, 1902. Serial No. 102,649. (No model.)

To all wtont it may concern:

Beitknown that I, WILLIAM P. QUENTELL, a citizen of the United States, residing at Manhattan borough, New York city, in the county of New York and State of New York, have invented new and useful Improvements in Type-Writing Machines, of which the following is a speciiication.

This invention resides in certain novel features of construction set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure 1 is a plan view of the machine. Fig. 2 is a sectional elevation of Fig. 1. Fig. 3 is a section along :c rc, Fig. 2. Fig. 4. shows a modification in plan view. Fig. 5 is a front elevation of Fig. 4.. Fig. 6 is a pian view of a further modification. Fig. 7 is a plan view of another modification. Fig. 8 is a sectional elevation of Fig. 7.

The machine is shown with a type segment or wheel 1, made to vibrate or give a printing motion or stroke on platen 2, which latter or its carriage travels on or across the base 3. The combs or

guides

4 and 5, with fulcrums '7, 8, and 9, serve for the proper mounting and movement of key-levers l0, which can have nger-buttons 11, as usual. On ashaft 16 are sleeves or bearings 17, Fig. 1, of levers or arms 19, Fig.l 2, connected by link 19 with lever or bail 18, actuated by the key-levers. Two levers 19, with their respective parts, are shown; but the description of one eX- plains the other. As one lever19 orthe other is actuated it strikes shoulder or disk 21, Figs. 1 and 2, so as to oscillate this piece, with rock-shaft or sleeve 22, carrying arm 23, with segment 24, engaging gear 25 of the typewheel or its shaft. As the gear 25 is oscillated one way or another with disk 48, having connection hy means of pin 2G with the type -wheel, the latter is turned or set to bring a required type to the printing position. The type-wheel shaft 27 is shown with a sleeve 29, rotating with gear 25 and carried by frame 30, vibrated, as presently explained, for the printing stroke. With this sleeve rotates a pinion 37, engaging a segment 36, having an arm 39, adapted to he stopped or arrested by the pins 18', each of which is lifted or moved to stopping position by its respective key-lever when depressed. When a keylever is depressed, it lifts a pin and actuatcs levers 18 and 19, which latter rotate the typewheel and pinion 37, so as to swing stop-arm 39 until stopped by the pin which has been raised or brought by its respective key to arresting position. After the rotation of the type-wheel is stopped the continued pull of

levers

10 and 18 causes frame 30 to swing, so as to dip or strike the type-wheel against the platen. The operation of this part of the device with lock or pawl 43 and hook 44 being set forth in United States Patent No. 698,318, granted April 22, 1902, for type-writing machine no detail description thereof is thought necessary here. The arm 39 and row of pins 18', extending each side of the center line of the machine, are shown not parallel with one another, but in curved relation to one another. It is evident that the arm and pins must be so arranged that the wheel can turn more or less to bring the required type to printing position before the arm or the rotation is stopped. The arrangement shown has been found compact; but of course the invention is not confined to this configuration, as any suitable arrangement can be applied. A returning spring orsprings 38, connected toaforwardlyprojecting arm of levers 19 or their sleeves, can reset the parts after the key is released.

In some of the so-called wheel-machines an escapement is provided for allowing the wheel and paper to come to printing-contact at the proper moment. In this construction here shown the wheel moves to the paper and the escapement is provided for holding the wheel against dipping or tilting prematurely or while rotating and allowing the wheel to print or strike to the platen at the proper moment. The escapement is shown comprising a hook 4.4, which when engaged by bail or lock 4.3 holds the wheel against tilting. This printing-escapement is connected with the stop arm or bar 39, so as to be released when the stop arm or bar is arrested by a stop 18. The escapement is connected with the stop-arm, or rather a lever on said arm, by a link 7l, having a ring-flange or disk 72, sitting loosely about the sleeve or shaft of stoparm 39 and over the horizontal arms of a three-armed or bell-crank lever 73, pivoted or fulcrumed to said shaft. This lever 73 is jointed to or actuated by lever 74, fulcrumed on stop-arm 39 and having projections or T- tail at 74', projecting beyond each side of arm 39 when the lever 74 lies parallel along said arm. As the arm 39 comes against an elevated stop the lever-tail also being pressed against such stop will oscillate or press lever 74 to an angle with arm 39, and the consequent swing of lever 73 will raise the link 71 and lift or move lock or pawl 43 out of or clear from hook 44. Said'

parts

43 and 44 can be conveniently called a printing-escapement for short. As the key-lever continues to move bail 18 and pull link 19' the frame 30 with wheel 1 is drawn or pressed to the platen. When the stop or bail 43 engages the arm or depending part 44 of frame 30, the latter'is locked against vibration, so that the type-wheel cannot dip. A spring 76 can be applied to return the lock or escapement 43 or hold the latter normally in engaging position. The ribbon or inking device is not shown, as any suitable ink-roller will do. The case-shifting movement of the type-wheel or its shaft 27'can be effected by lever-arm 55, fulcrumed at 56 and having an arm 58, suitably lifted or actuated by one or more properly-arranged shift-keys. The levers 19 when at rest or in normal position lie against suitably-adjusted stops or screws 65 on frame 30. A stop 66 limits the upward swinging of the type-wheel-that is, the backward swing of arm 44.

In the modification shown in Figs. 4 and 5 the lever 73n is not engaged directly by lever 74a, but the latter engages the fork or arms 75a, depending from the rock-shaft or fulcrum of said lever 73u.

A method which may be preferred or is simpler, as shown in Fig. 6, is to omit lever 74 and leave the fork or yoke 75b in such position as to be carried against stop 18 to be swung or oscillated for actuating rock-shaft or fulcrum 771 of bell-crank 73h.

In the modification shown in Figs. 7 and 8 the stop-arm 39 instead of swinging about a center forms part of a rack 36, reciprocating along the race 35C, forming part of or depending from frame 30C. The arms 39c have pivoted thereto levers or arms 74C, which when struck or brought againsta stop-pin are moved or swung to press forward the slide or bar 72C, actuating lever 73C to move link 71C and free the escapement.

I do not herein claim to be the inventor of the combination, with a type mechanism, of a bank of keys, operating mechanism between the keys and the type mechanism, means for holding the type mechanism from movement in one direction, a single locking mechanism for holding the type mechanism against movement in the opposite direction, releasing means for said locking mechanism, and connections whereby said releasing means is op.- erated when a key is operated.
