TYPEWRITEB ACCENT-KEY ATTACHMENT.

Application filed November 17,1919. Serial No. 338,518.

To all evil om it may concern:

Be it known that 1, .ALroNso Hnmno, a citizen of Chile, South America, and a resident of llrooklyn, in the county of Kings and State of New York, have invented certain new and useful improvements in Typewriter ilccentdiey Attachments, of which the following is a specification.

The principal object of this invention is to provide a simple, practical and inexpensive attachment designed to permit the printing of various accent marks, as used particularly in foreign composition, without the necessity of back-spacing or w1th regard to the position of the key that carries the accent mark on the key board.

Another object is in the provision made i for quickly andconveniently attaching the device to models of the well known itemington typewriters without having to disassemble but few of the machine parts.

A third object is in the means employed for connecting a number of keys when a plurality of accent marks aredesired;

These objects are attained by the novel construction and combination of parts hereinafter described, and shown in the accompanying drawings, forming a material part of this disclosure, and in which Figure 1 is a partial sectional and side elevational view showing the application of the invention and its relating parts.

Fig. 2 is a partial sectional view taken on line 2-2 of Fig. 1. i

Fig. 3 is a perspective view of the attachment in a relatively assembled position, and

Fig. t is a perspective View of the dog actuating lever, showing it as changed from its initial form.

Referring to the drawingsin detail, the numeral 10 designates a key lever pivotally secured at the rear end upon the rod 11 and held thereto by the pull of the spring 12.

A universal rocker shaft 14 is initially operated by the bell-crank lever arm 15, by

the universal bar 16, when the key lever 10 is depressed, and has secured upon it the ribbon vibrating arm 17 to wh ch is secured the escapement arm 18, having upon 1ts outer end a hooked element 20 designed to engage the forked end 22 of the dog rocker link 24.

The forked end 25 of the link is pivotally engaged with the escape lever 26, and attached to the escapement dogs 28 which are pivotally mounted at the point 30 to the machine frame.

A rocker rod 35 is provided with angularly extending arms 35' which are rotatably mounted upon the universal rocker shaft'l land held from side movement by the collars 36 clenching the shaft 14.

An angulanupturned arm 37 fixed to the rod 85, terminating in the abruptly bent projecting arm 38, parallel with the rod 35, is designed to contactably engage the forked end element 22 the link 24 and by a downward movement, imparted by a quarter turned double end hook 4:0, engaged at its lowerend with the key lever 10, the element 22 is pushed outward away from the hook end 20 of the escapement arm 18, which action disconnects the link 24: from its normal position and prevents'operation of the escapement mechanism. The escapement arm 18, prior to attachment of the device has the outer prong 21 out off, as best shown in Fig. 4.. I

A wire guide 44: is rigidly secured upon the arm 18, the guide projecting rearward and terminating in an abrupt downward bend at, positioned within the forked element 22, acting'as a guide for directing the 7 return of the link 24: to its normal position,

the return being accomplished by the pull of the U shaped spring 415, secured upon the ribbon feed rod 46, upon releasing the key lever 10.

Coincident with releasing the key lever 10, the rocker rod 35 is drawn upward and away from the link element 24 by the pull of the tension spring 18, secured at one end to an eye 49 formed with one of the rod arms 35, and having its other end attached to a pro jecting wire arm 50, secured to the type bar segment 52 by the screw 53.

In operation, upon depressing any key lever connected to type-bars carrying accent characters, the rocker arm 37 is drawn down ward by the double hooked connecting wires, causing the outwardly projecting element 38 of the rocker rod to engage with and push from its normal position the escapement connecting link, thus breaking the me chanical connection with the escapement mechanism and rendering the carriage feed inoperative, but permitting the ribbon vibrator mechanism to function in the regular manner and allow the printing of the accent mark.

Ag releasing the key lever effects no car- Specification of Letters Patent. t nt Jan. 13, 1921 r riage movement, the platen and paper are still in position to receive in the proper place the imprint of the letter it is desired to accent.

Upon releasing the accent key the rocker frame arm is returned to its normal position by the upward pull of the spring 48 provided for this purpose and attached to the wire arm secured to the machine, permitting the escapement connecting link to assume its normal position on the lever hook, guided by the guide wire -14; attached to the lever and asslsted in its return by the looped spring engaging link and the ribbon shaft.

If a number of different accent marks are required a plurality of the double hooked connection wires 40 may be placed upon the rocker arm at points vertically alinable with the key bars connetted with the desired accent marks.

In assembling the hook element 21 is cut away as shown by dotted lines in Fig. 4

p and the universal rocker bar removed for the purpose of putting on the rocker arm and attaching the guide wire, after which the rocker bar is replaced.

Having thus described my invention what i cafm as new and desire to secure by Letters Patent, is

1. In a combination with a typewriter having accent keys, a universal bar, an e scapement arm fixed on said bar, an oscillating escapenient and a link operatively conne ting said escapement and said arm, said arm permitting the removal of said link, a rod and means carried thereby for guiding said link relative to said arm, means for dis engaging said link from said arm when the key levers are depressed and spring actuated means for reengaging said link upon the release of the key levers.

2. In a combination with a typewriter having accent keys, an oscillating escapement, a universal bar, a dog rocker shaft actuated by said bar and a link extending from said escapement, of a lever fixed on said rocker shaft normally engaging said link, a guide for said link secured on said lever, a rocker rod pivoted on said rocker shaft, an arm formed with said rocker rod contactable with said link, and operative connections between said rocker rod and the levers of said accent keys whereby upon the depression of the levers said arm causes said rocker rod arms to disengage said link from said lever.

3. In combination with a typewriter having accent keys, an oscillating escapement, a universal bar, a do rocker shaft actuated. by said bar and link extending from said escapement, of a lever fixed on said rocker shaft normally engaging said link, a guide for said rod pivoted on said rocker shaft, an arm formed with said rozker rod contactable with said link, means for normally holding said arm in a raised position, means actuated by the levers of said accent keys for disenga ing said arm from contact with said lin and means for returning said link into engagement with said lever.

In testimony whereof I have signed my name to this specification.

ALFONSO HERING.
