' Specification of Letters Patent.

Application filed-January as, 1904. "Serial No. 190,668.

-State of New York, have invented certain newand useful Improvements in Ty 0-- Writing Machines, of which the following is a specification. 1

- My invention relates to improvements in the. t e actions of typewritmg machines, especia y those visiblewriting machines which are known as front-strike machines, the general object of the invention bein to prevent the type bars from rebounding w lien they return to their normal positions, and a further and special object being to rovide anti-rebounding means for the type are of machines containing type bar hangers which Is from a common hanger-support.

The invention .consists of various features of construction, combinations, and arran e- .ments of parts, all to be hereinafter fu y described and particularly pointed out in the ap ended claims.

' n the. accompanying drawings wherein likereference numerals designate 'ke parts in different views, Figure 1 is a sectional elevation, showing portions of the frame and mechanism of a front-strike .typewriting machine embodying m invention, the section being taken contra y'and longitudinally of the machine; Fig. 2, a side elewation on an enlarged scale of a type bar hanger, a fragment of a type bar pivoted theretd'a locking device and a fragment of'an actuating Fig. 3, an edge view of the loc "device and cross section of the type bar, viewed in the direction indicated byth'e arrow 2'; d Fig. 4, a perspective of thedocking dev1ce..

. Although no and detachable-typ bar hangers? are secured, itis to be understood that the invention is applicable to machines of other styles, and

especially to type actions whose type bars are pivoted to a common supporter rod instead of to se arate hangers.

The frame 0 the machine represented by the drawings is composedof a base 1, the

common corner posts 2, and two other similar posts, and the top late 3 secured on these corner posts, the si es ofthe base invention is shown applied- .-faces of eac to a front. st emachine containing a segmental type bar support to which-separate platen 5 is indicated ,by thecircle which, ap ears above the top plate 3.

tact wit a padiO-afiixed to t e cross bar. 4-,

fixed cross bar 11 and bearing against the lower. edges of the keylevers. A sub-lever 12 issecured to each key lever by a pivot 13,

there being at the lower end of each sublever a'slot-14 in which is a rod 15 which extends from side to side of the which it is supported at its ends.

,In' front of the'upper'ends of the sub-levers 12 is a segmental type bar support 16, which is similar inform tov the type bar segment of base, by.

rod 8, which may be attached at its ends to Each key lever isnormall held byv a restoring spring!) inconthese restoring springs being fastened to a the machine known as the Monarch, the front and rear faces or edges of this segmental support being preferably parallel to a vertical prlane tangent to the front of the platen, and in out ofand behind said plane respectively.

This segment may be movable vertically on fixed guides to. shift the system of type bars for. u per or lower case printing, or, if 7 referre the platen may be shifted when it is desired to use upper or lower case'charac ters. Mechanism for shifting the 1sfystemof type, bars and mechanism for sh' ting the platen being well known, it is unnecessary tov ere describe shifting mechanism for either pur e. The su rtori segment 16 has its ront portion a series of slots 17, -wh1ch extend from its up er or concave face 18 to its. I

.lower or convex ace, the concaveface being a cylindrical surface whose axis passes throu h,

or near the rinting point on the platen. v

lislot 17 areon o posite sides of a plane containing and radiating from the axis of the surface 18. A type bar rest, composed of a segmental support 19, and a pa'd20 secured. on the concave face thereof, is'afiixed to 3 I an arm 21 and another similar arm which are rigidly attachedto the segmentflfi near 1ts lens.

Although the ype'bars of tfiie actions. embodying this invention may stantially the segment 16, it 'is' not regarded necessary to show other means by which the.

va by other meansthan separate hangers on 'sub-:

, similar segment.

' stood.

From the description of the type actions herein shown, and which include separatetype bar hangers, the prin-' slopes from top to bottom towards the front of the stem as appears by Fig. 2.

26, formed by the bottom ofthe head and back of the stem, is a right angle.

The angle The stems of the hangers fit snugly in the slots 17 of the segment 16, and when the hangers are proper y secured to the segment the backs of the stems and the lower edges of the ,heads are in I contact respectively with the ends of the slots and the concave surface 18 of the seg ment', the heads extending nearly across the segment. Each hanger is fastened to the segment by a screw 27 which is screwed into a threadedhole in the front of the segment and against the rear edge 25 ofthe notch 24;

so that the sides of'the angle 26 are. forced and held tightly against the segment. The heads of the han er's form sockets for the type bars, which t closely between flat surfaces'within theheads, each type bar 28 being ivoted to its ,han er'by' a ivot 29 exten 1n through both 0 reeks of t 1e head and the type bar, whose end is indicated throu v by a ottedline in Fig. 2. On the-front of each head is formed a-catch 30, the front edges of the cheeks of the head being curved above-the catch, as a pears at 31, to form a guide for the'locking evice o r latch.

In each of the typebars is a recess 32, whose edge 33 is evenwith the face of the catch when the type baris in its normal position.- The locking device or latch 34 is pivoted by a pin 35 130 the type bar, This atch, which extends'on opposite sides of and across the type bar, has at its lower end a device 36to engage the catch 30, and forms at its other end cars 37 which extend beyond the adjacentedge of the type bar. 'It preferably consists of a single strip of sheet metal bent parallel to itself, as appears by Figs. 3 and 4, the bent part 38, when the latch is secured to the type bar and engages the catch 30, being close to but not in contact with the edge 33 of the recess 32 in the type bar.- The latch is movable on the axis of its pivot 35.

from the osition shown Fi' .'1 'to that shown in igu2, and when'it is 1n the latter position the bent'part 38 is in Contact with the ed e 33 of the recess 32. This latch is also a key. actuated lever, operative on the type bar to swing it to its-printing position, under the action-on this lever of the key lever and other mechanism connected therewith, as'

will be hereinafter described.

An actuating link 39 is pivoted at its rear Y be actuated by it.

is drawn backward by the sub-lever.

tion the forward action of the link 39 on the latch immediately forces the engaging device- ;36 of the latch under the catch 30 on the end by a pin 40 to the upper end of each of the sub-levers 12, and each of these links is pivoted by a Jin-41 to and between the cars 37 of the late or lever 34 of the type bar to Coil springs, like the spring 42, are attached to the type bars and to hooks or pins fastened to thetype bar rest, the functions of these springs being to aid in restoring the type bars to their normal positions,

The several. parts of the type action described are shown in their normal positions in Fig. 1. When. a key is depressed the key lever. carries downward the sub-lever 12 mounted thereon, and as the sub-lever dcscends its upper end is moved backward in consequence of the action of the u per edge of the slot 14 on the rod 15, and t 1e linkri39 1c latch 34 is disengaged from the catch 30 at the beginning of the backward 'movement of the link 39, the latch being turned on its pivot 35 tothe position shown in Fig. 2, whereupon the bent part 38 of the latch makes contact with the type bar. The latch therefore constitutes a lost-motion connection between the actuating link 39 and the type bar, for during the movement of the latch onits pivot asdescribed, no motion is im arted to the type bar by the actuating link. Upon thearrival of the latch at the position shown in Fig. 2, the link 39 becomes operative through the latch to actuate the type bar by swinging it on its pivot 29 to its pr nting position, the latch then acting as a ever and revolving meanwhile on the axis of the type bar pivot, but being prevented from rotating on itsown pivot by thecontact of the part 38 of the latch with the type bar. The type action is restored to its normal osition by springs 9-and 42 and by gravity. hen the type bar reaches its normal posihanger, the latch, prior to its engagement with the catch 30, hearing against the curved edges 31 of the head of the hanger, if the return movement of the link 39 is quick enough to separate the part38 of the latch from the edge 33 of the recess 32 of the type bar. The latch then positively prevents the type bar from rebounding for it so locks the type bar that the latter cannot turn on its pivot until the latch is withdrawn from the catch latches like the latch ment of the link 39'is bar will be tion by the latch. It will piixilshed towards its normal posik 39 acting on it through the be seen, therefore, that the part 38 of the latch is operative on'the edge clear to' limit the movement of the latch on its pivot in op osite directions.

n'iovable locki and they afl'ord n additionto the special ad: vantages of this invention, allthe well known advantages which are derived from other ty e actions rovided with such hangers.

It will beoliaserved that the device or lever 34 aii'ords the'advantage of ,a lost-motion connection between the finger key and type bar and renders the action of .the ke very light at the beginning. of jthe stno e. Av

similar lever may'thereforebe used for this purpose alone, and when it is, 'of course, it

does not need to be provided with'the engage ing device36, 01? (it as described, to prevent it from rebounding. Certain features of, the invention may be used without-the; others and various changes may be made without, departing from the spirit ofmy invention,
