i t I the city of lllizztheth, count oi l nion, nnd

State til New Jersey, have inv nted ccriztin new and usei'ul lmprtiveinents in 'i ype-ti'riting Machines, oi' which the i'ollon'ing is at spcciiieetit'in.

'lhis invei'ition relates to the i -nt:tions oi writing mnrhinos, especially" those in Which type hnrs st riize upon the i'ront side oi at plitten.

The chief o'oject oi' the invention is to render the key touch more iigreenhle and the operation oi the imichino less fatiguing, and especially to make it pine-tieuhle to vary from an exceedingly still, resisting ztt'tion oi the keys to a. very ehtstic netion. so as to suit the requirements ot' all classes o i OpOltti ors.

I Still ztwztre that it is rust omnry to provide an adjustnhle he tension," hut, the rnne e of such adjustment is snntll, owing to the necessity oi applying; sutlicient tension to return the keys and tmernted pints promptly to normal position. According to mypri-sent improvements, the s -nll(. .d "key" tension."

or linger tension. nnty he adjusted 213 here toforc. so as, to client the retpnsite prompt action of the parts, while it is also possihlev by means of {1. separate mljustment, to eti'ent Wide variations in the key resistance, preterahly without distnrhing the said adjustment 0] the usual keytension,nml so that: the ins chine is caused to respond promptly. whether the touch oi the keys he either extremely light, medium. or extremely lntrd.

My invention. consists in certain comhimttions of devices, features of construction, and organization oi pzn'ts, nil as will he l'iereinnl ter fully set forth. and particularly pointed out in the concht ling claims.

The movements of the pztpcr carriage may be controlled hy ti curved lllllVCl'tStl inn is. netunl le in; any type inn, and having :1 sniizthle (bonnet-lion. as indicated at 19, \yherehy itv may opeinte tin.- nsunl letter-spacing dogs (not Shonni. universal hernia)" as usual he provided ith a returning. spring); (not. shown), to cooper-- ntc with the spring to in returning the type hnr and key to nornnil position; :md ls-otl' the universnhhn may he adjusted as retptiretl, to :renre prompt notion oi the t pc inn :ind ttnrringt feeding meehnnisdns,

in the preierred n'nmnt'r oi practicing my invention, the lie lever l l is (1 oil nt. its rem portion to iorni tines .-.t) end 2'], prei'erithi spring; and the spring to placement and tipping are prevented by forwider and hence stiffer than the lower tine 1 before the upper tine or lender is arrested 21, although it is not essentialin all cases by contact with the under side thereof. At

. that one tine be stronger than another, nor

that the tines be of equal length, nor formed integral with the lever, nor placed edge to edge one'above the other as illustrated. fine of the tines, preferably the lower, may hear at its tip against the under side of a fulcrum bar 23 extending transversely at the rear of the system of key levers (Figs. 1 and 3). Fore and aft displacement of the lever is prevented in this instance by its attachment at 13 to the sub-lever 12, and lateral disward and rear guide-combs 24 and 25, the latter-guiding the levers at theircleft portions. The spring 16, through the bell crank 12, tends normally to hold the key lever up at its rear and against said fulcrum bar 23, its forward portion bearing up against a fixed pad 26. r i

The lower tine 2-1, which is subjected to a bending stress when pressure is applied at the key, is preferably so still that when the key is depressed. with moderate speed the type bar is'carried to the platen and makes an impression thereon without flexing said tine, as illustrated at Fig. l, the upper tine 20 being idle; but when thekey is struck sharply, said tine 21 flexes or yields, as at v Fig. 4, thusavoiding a jar to the finger, or

cushioning the touch of the key. it will also be understood from said figure that the upper tine 20, by acting as a guard or fender, 35'

prevents undue tlexure or total collapse of the weak tine 21, since the tip of said tine 20 when thrown up contacts with a stop 27 whereby the key lever as a whole is stiffened,

and excessive bending of the lower tine is prevented, although the movement of the key lever and type bar is not obstructed.,, Thus it will be perceived that the touch of the keys is rendered always soft and agreeable, and that there is no jar to the fingers when operating the keys rapidly.

The response of the mechanism may be made very prompt by putting suit-able tension upon the springs 16 and the usual universal bar spring, "without rendering the touch harsh, since such spring adjustment does not affect the yielding property of the key lever.

The stop 27 which extends across the machine above the key levers, is preferably cylindrical in form and mounted eccentrically in the side walls of the base upon pintles 28, upon which said stop bar may be turned andhence adjusted up and down with relation.

tothe key levers. One of the pintles may be provided with a lever or key 29, for facilitating adjustment of the stop bar; and a friction washer 30 or other means may be added for holding the latter where adjusted.

' The position of said stop-bar determines the 'cxtent tov which the lower tine 21 may llOX h ig.'5 the stop bar is shown adjusted to a low I position, so that very little such flexure is permitted, and the key action is accordingly rendered much stiller to the touch, although cushioned at the initial portion thereof. By adjusting the stop bar to different positions, the touch may be rendered very soft, as at Fig. 4, or very stiff, as at Fig. 5;, or set to some intermediate point, according to .the desire of the operator, without, however, altering the tension of the usual key lever springs 16 or the usual universal-bar spring, so that-the spring may be caused to act as promptly as desired for'both hard and soft key strokes. Moreover this variation in the touch may be effected by the operator without liability of deran'ging the action of the delicate carriage-feeding mechanism, and

without the necessity of employingrnechan yielding action thereof while permitting the kej, s to carry the types tothe printing point that each, of the key levers has a yielding construction, preierably at. the'fulcrum portion or end thereof; that each leveris preferably cleft from its load point to its fulcrum point, and preferably so as to form tines'ol" unequal stillness, the weaker tine preferably serving as a fulcrum arm for the lever;

that the body portion of the lover, or from' the load point to the key, is preferably stiller than either of the lines 20, 21; that-'a plurality of devices, as 23 and 27, commoifto said levers, are engaged by the plura ity of sets of tines; that the limiting stop 27 is preferably near the lever fulcrunis that said device 27 enables the tines 20 and 21 to cooperate to stillen the lever; that means are provided upon the framework of the machine for limiting the j) ielding action of the key levers while permitting'lho actuation'ol the t} pe by the key; and that the. yielding ac.. tion of each lever is independentof the other turbed' 1 am aware that it has been proposed to .employ a yielding construction between the key and tj\pe bar; but such devices have proven unsatisfactory in prar'lioe, and are not capable of performing the functions of my invention. ()ne of the leading f at-t res of my" im rovenienis consists in the iovision of means for securing a wide range of nation with adjustment of the finger touch, especially where the adjustment is etl'ected simultaneously for all the keys hy means of a single finger-piece, requiring no mechanical skill upon the part of the operator, so that he may readily adjust the machine to suit. his individual touch, or may vary it from time to time to adapt the machine for particular kinds of work or conditions of operot ion.

lViile l prefer to employ a tined lever, still my invention may he carried out Without using levers of this nature, certain fee.- tures'of invent ion, l;roa1.lly considered, hein; independent of the construction of the key lover, or of any lever which transmits the key movement -to the type, so long as pro vision. is made for the specified action of the keys.

Many Vililt'lllOllS in construction and errengeinent. may he resorted to within the scope of my invention, which is applicable also to other styles of'writing machines. Portions of my improninents may he used Without others.
