TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed March i, 1913. Serial No. 758,630.

To all whom it may concern:

Be it known that I, lVARn S. IRELArm, a citizen of the United States, and a resident of Owensboro, in the county of Davie'ss and State of Kentucky, have invented certain new and useful Improvements in Type- VVriting Machines; and I do hereby declare which thepaper is fed forward with each manipulation of a key or of several keys simultaneously.

\Vith this object in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of a stonegraphic typewriting mechineembodying my improvements. Fig. 2 is a view in perspective showing the paper feeding mechanism; Fig. 3 is a view partly in section showing the paper engaging fingers and wheels or disks with which they cooperate, and Fig. t is a sectional view on the line yi of Fig. 3.

1 represents the frame of the machine, wherein is pivotally mounted a plurality of key levers 2 provided respectively with keys "or buttons 3 and with upwardly projecting arms 4. A notched bar 5 is disposed transversely in the upper portion of theframework intermediate the ends thereof and in this notched bar a plurality of type levers 6 v are pivotally supported between their ends and each provided at its upper end with a type 7 ,the lower ends of said type levers being .pivotally connected with the upper ends of the key lever arms 4.

ars 8 are located on the frame 1 at respeetive sides thereof and to the forward ends of these bars, links 9 arehinged and supported by the framework. The forward ends of theselinks are provided with elongated slots 10 for the reception of screws 11 whie h adjustably connect a transverse "platen bar 12 .between said --links ----said platen bar being thus disposed transversely over the central and directly in line with the type 7. -The platen bar is preferably provided with a yielding strip 01' platen 13. Itwill be ap parent that by mounting the platen bar adjustably as above explained, the yielding Patented May 26, 19 14.

ortion of the framework platen face or strip can be adjusted toward and from the engaging faces of the type.

A shaft 14 (mounted in the bars 8) extends from one of said bars 8 to the other and upon this shaft, a plurality of wheels 01 ' disks 15, 16, 17, are mounted.- Levers 18 are mounted between their ends'on theshaft 14 in proximity to the bars 8 andthe upper ends of these levers are provided 'with pins 19 on which spring actuated sleeves 20 are mounted and each of these sleeves is provided with an engaging finger 21 which oooperates with the wheels. or disks.15 17 to iced thepaper as presently explained. A yoke 22 is secured at its ends to the bars 8 of the framework and the intermediate'portion of this yoke is provided with lugs 23 which support a pin 24; for the accommodationof a spring actuatcd sleeve' 25 carrying a finger26 to cooperate with the intermediate wheel or disk 16 for preventing retrograde movement of the paper. The yoke 22' is also provided with a serrated or toothed edge 27 to facilitate the ready severance of the paper strip. 5

Standards 28 rise from the platen bar 12 and between these standards, guide rolls 2930 are mounted. A guide 31 is disposed below the platen bar and may be in the form of an integral flange depending from the lower edge of the platen bar 12. A door 33 is provided for the rear end of the frame or casing of the machine and this door carries a bracket 34 in which a roll of paper is mounted. The paper strip 36 extends from this roll under the guide 31; then updownwardly and around the roll 30 and upper guide roll 29. After passing over the roll 29 the paper strip is made to pass downwardly and around the roll 30 and from the latter, the strip passes rearwardly over the wheels or disks 15, 16, 1'7 and under the fingers 21 and 26. A guide plate 32 is provided for assisting in the threading of the paper past the roller 30.

A universal bar 37 is supported by links "hey lever aims-4"ana reerau providedwith a cushion 3910 be. engaged by said key lever arms; The links 38 are made in the form of arms rising frombars l0 which project rearwardly from the ends of; the-univere sal bar and to the'rear endso-fsa'id bars 40 links 41- arepivotally attached, the rear ends 1 tailed description of the same will be superfluous,-obut sufiice itto saythat the ribbon 4:3 is caused to pass between thetype and the paperstrip f It willeobserved that the paper strip is bowed or loose betweemthe guides 31 and 29 and also between the guides 29 and'30 and that when a key lever is operated, the typefw-illbe 'causedvto imprint on'this' loose or [bowed section of the paper strip. It will -also be observed'that when 'a" key lever is operated, the engagement of its arm 4 with the universal bar-37 willcause'motion to be transmitted through the arms 40 and links :41 to the levers 18. Said levers will thus "t paper stri operation of springAQi be caused to rock and to move the fingers 21 and, said fingers being in engagement with passing over the wheels or disks 15' a r-d1 will cause said-paper strip to be moved forwardly a distance 'suflicient to receive another lineflof writing. When the paper strip is thus moved, retrograde;

movement thereofwill be prevented by the finger 26 in cooperation with the wheel or disk les ilVhen the key lever shall have been released, it will be returned to 'itsjnormal position bythe action of a spring 4:4 and the H maining parts of the mechanism will be returned to their normalpositions by the The connecting devices between the'universal bar and the paper feed devices, should be such that the completion of a feeding movement of the paper and the engagement of a type withthe aper will be practically simultaneous, and or this reason, the uni versalbar isprovided with a finger: 4:5

which, in cooperation with a 'padglfi, constitutes a yielding stop" forsaid universal bar and the. parts which it "controls; As paper feeding fingers and type bars are both moved simultaneously by the universal bar, 'the fingers will feed-paper as long as a type bar moves. If the type bar-moves -after gripping to the platen, on account of pliability of platen face, the fingers will'be feeding paper forward after the. type has caught the paper and-held it; hence there must be some slack in the paper between type and fingers for the fingers to feed to prevent their c'atch ing the aper and tearing it. By arrangm the ui es forthe paper in front of an above the platen, in the manner .hereinbe- [fore described, andclearly shown'in Fig. 1 of the drawin sufiicient distance between the guiders. an the platen will be provided to enable the resiliencyof the paper to pro-' duce, the slack in the paper, which can be taken up--by the feeding fingers after the type strike.

Having fully described my invention what to secure by Letapluralityofpivote'cl levers, spring pressed fingers carried bysaidlevers and adapted to cooperate with said'disks or wheels, a plurality of key bars, auniversal bar operable by the key bars or levers, and connections between, said universal barand thefirst.

mentioned levers. o i 2. In a paper feeding mechanism for typewriting machines, the combination with a frame, of a plurality of wheels or disks,

fingers carried by said levers and cooperating with certain of said wheels or disks to feed a'paper sheet, a spring pressed finger carried by a fixed support and coiiperating with another of said wheels or disks to prevent retrograde movement of the paper sheet, kpy levers, a universal bar, and connections between the universal bar and the first mentioned levers. p

i 3, In a typewriting machine, the combination of printing means, paper feeding means, m eans below the printing means for loosely supporting'a supply of paper, paper guiding meansbet een the printing point and thepaper feeding 'means, said paper guiding means havingsuch relation to the printingmeans as to cause the resiliency of the paper to slacken the latter above and past the printing means when the type of the latter recede.
