Specification of Letters Patent.

TYPE-WRITING MACHINE.

Patented Sept. 12, 1905.

Beit known that I, GEORGE B. W'unn, a citizen of the United States, and a resident of lVestfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in 'lype-iVriting Machines, of which the following' is a specification.

This invention relates primarily tothe typeactions of front-strike writing-machines; and its main objects are to assemble a large number of rearwardly-striking type-bars compactly below the printing-point with wide bearing's or hang'ers, so that they may be guided accurately to the printing-point; to improve the arrangement and construction of the connections between the keys and the typebars; to provide improved means for adjusting' the key-levers; toimprove the mounting of the key-levers; to provide for the convenient detachment of the links'employed in the type-actions; to provide improved spring mechanism for returning the key-levers and type-bars. and to render the touch of the keys more agreeable and to insure the prompt rebound of the types from the paper, so as to avoid blurring' of the impressions.

Other objects will hereinafter appear.

My invention consists in certain combinations of devices, features of construction, and arrangements of parts, all as will be hereinafter fully set forth, and particularly pointed out in the concluding' claims.

In the accompanying drawings, Figure 1 is a central vertical section taken longitudinally of a front-strike writing-machine constructed inaccordance with my improvements, the parts being' shown in normal position. Fig'. 2 is a front sectional elevation of the machine, taken just forwardly of the system of type-bar connections. Fig. 3 is a diagrammatic plan of the key-lever system. Fig. et shows the position of a type-action when the key is arrested and just before the impression is made. Fig'. 5 is a perspective view of a frag'ment of a keylever -returning' spring' mechanism. Fig. 6 is a detailed edge view of one of the connecting-links.v

ln the several views portions are omitted or broken away to disclose the invention more clearly, and similar parts are designated by similar numerals of reference.

The framework of the machine comprises a base 1, upon which are erected corner-posts 2, supporting' a top plate 3, which is provided with an opening' 4 for the passag'e of the types. The machine is of the full-keyboard type and is provided with four lower banks of keys 5 for lower-case letters and figures and four upper banks 6 for capital letters and other characters. The keys are carried upon the forward ends of rearwardly-extending levers, which are fulcrumed at their rear ends and arranged in two tiers, those in the lower tier bearing the forward keys 5 and being' designated as 7 and those in the upper tier bearing the rear keys 6 and being' designated as S. The lower key-levers T project rearwardly beyond the ends of thel upper keylevers 8 and are fulcrumed upon two transverse rods 9, arranged one above the other, while the key-levers 8 are fulcrumed upon two similarly-arranged rods 10. The several rods are mounted upon an inclined plate or bar 11. which extends across the base and is secured at each end to the side walls thereof by screws 12, said plate being provided with four forwardly and downwardly projecting longitudinal bearings or ridges 13, which are vertically slotted at 14 for receiving the rear ends of the key-levers and are also provided with horizontal grooves 15 for receiving' the fulcrum-rods 9 and 10. The latter, it will be seen, are arranged in forwardly-ascending series, the lower and rearmost rod 9 bearing the key-levers for the two forward banks of keys, the next rod serving for the next two banks of keys, and so on. lhe fulcrum end of each lever is cleft at 1G, so as to enable the lever to be sprung upon the rod, a notch 1T being formed in the cleft portion of the lever for engag'ing the lower side of the rod.

The type-bars are pivotally supported below the platen 18 by means of separate hang'- ers fastened upon a downwardly and rearwardly inclined segment 19, the latter being secured at its ends to the underside of the top plate 3. The type-bars strike upon the platen at a point a little below the levelof the platenaxis. The purpose of arranging' the type-bar pivots in a rearwardly-inclined are is to enable the type-bars at the sides of the system to drop more freely back to normal positions after actuation than is the case where the typebars are pivoted in an arc lying' in a vertical plane, as usual heretofore. ln other words, the fact that the pivots of the type-bars are mounted in a rearwardly-extemgling' inclined IOO ' point.

plane results in the pivots extending back of the front face of the platen or in the rear of a vertical plane that extends through the point of impact of the types on the platen, so that the type-bars do not extend vertically over their pivots when they (the type-bars) are in the printing positions and the force of gravity therefore enhances the rapid retrograde movement of each type-bar from the printing position.

The type-bars are disposed side by side in four rows or sets, their types accordingly lying in four curved rows in the type-basket 20. The type-bars in the forward set are designated as 21, those in the .next set as 22,

those in the next as 23, and those in the rear set as 24. rlhe bars 21 are pivoted on forked hangers 25, which are attached to a beveled face 26, formed upon the front edge of the segment 19. These type-bars are somewhat longer than those in the other sets, and their pivots are more remote from the printingers 27, attached uponthe same segmental face 26, the pivotal points of these hangers being above the pivots of the type-bars 21 or between the latter and the platen, so that the types upon the forward ends of the type-bars 21 and 22 may lie in alternating or staggering arrangement. The type-bars 23 are pivoted upon hangers 28, secured upon the `upper curved surface of the segment and are of about the same length as the type-bars 22, but are pivoted in rear thereof, so as to secure clearance at their type ends. The type-bars 24 are mounted upon hangers 29, fastened vupon the same upper, surface of the segment and are pivoted in rear of the type-bars 23. It will he seen that by pivoting the type-bars in four sets in the described manner a clearance is afforded not only at the type ends of the bars, but also at the hub ends thereof, thus enabling wide hangers or long pivots to be used, so as to permit free vibration of the type-bars to the printing-point without liability of lateral play. It will be understood that by giving the hangers an overlapping arrangement the desired length of pivots may be secured. The forward hangers 25 and 27 may be attached by screws 30, passing through the bases of the hangers and tapped into the segment, while the rear hangers 28 and 29 may be attached by screws 31, passing through the segment from the front and tapped into the bases of the hangers. Thus the heads of all of the screws are at the front of the segment, making it convenient to attach or adjust the hangers. The shanks of the forward set of type-bars 21 are curved downwardly near their hub ends, so as to enable them to clear the upper ends of the hangers 27, while the sets of type-bars 23 and 24 are arched at their rear portions, so as to clear the hangers 25 and 27, as well as the connections which are attached to the type-bars 21 and 22.

The type-bars 22 are pivoted in hang-y One set of connections extends from the forward sets of type-bars 21 and 22 to the lower tier of key-levers 7, and another set of connections extends from the rear sets of type-bars 23 and 24 to the upper tier of keylevers 8. Said connections include a system of converging or radially-arranged bell-cranks.

mounted in slots 32,cut upon the rear or lower edge of the segment,and pivoted upon a curved rod 33, seated in a groove 34, cut in the upper face of said segment. These hell-cranks are linked to the type-bars and are also connected at their lower ends, by means of forwardlyextending links, to a system of bell-cranks working in vertical planes and linked to the key-levers.

The connections forvthe forward sets of type-bars 21 and 22 include a set of thrustlinks 35, which are attached to the type-bars forwardly of their pivots and extend to the forwardly-projecting arms 36 of a set of radial bell-cranks pivoted upon the rod 33 and having downwardly-extending arms 37, the latter being connected by short forwardlyextending links 38 to the upwardly-directed arms 39 of a set of bell-cranks working in y vertical planes and having forwardly-directed arms 40, which are connected by pull-links 41 to the lower set of key-levers 7. The rear sets of type-bars 23 and 24 are connected by pull-links 42 to upwardly-extending arms 43 of a set of radially-disposed bell-cranks pivoted upon the curved rod 33 and having downwardly-directed arms 44, which are connected by long forwardly-extending links 45, overlying the short links 38, to the upwardly-directed arms 46 of another set of vertically-arranged bell-cranks whose forwardly-extending arms 47 are connected by links 48 to the upper key-levers 8. It will be seen that the thrust-links 35 occupy positions in front of the segment 19 and that the pull-links 42 overlie said segment; also, that the type-operating arms 36 of one set of radial bell-cranks extend forwardly from the curved fulcrumrod 33, while the corresponding arms 43 of the other set extend upwardly from said fulcrum-rod. It will further be understood that the bell-cranks .36 and 43 alternate, thereby giving ample clearance for the links 35, as

IOO

IIO

well as for the links 42, and it will also be seen that the arms 37 are longer than the arms 44,whereby clearance is afford ed for the joints at the rear ends of the links 38 and 45. The links 35 and 42 extend in radial directions or lie in planes which are radial to the printingcenter, in accordance with the directions of their respective bell-cranks and type-bars.

The forward vertical bell-cranks 46, which are of substantially uniform length, are mounted in groupsv at different elevations or in ascending series upon horizontal fulcrumrods 49, the latter being mounted in horizontal ledges or long bearings 50, which are formed upon the front face of a segment 51 and are provided with vertical slots 52 for receiving' the hub portions of the bell-cranks, there being one ledg'e for each group of the latter. The ledge-bearings 50 are arranged stepwise, beginning' at the middle lower p01'- tion of the segment with a long ledg'e, so as to accommodate a large group of bell-cranks, and thence ascending' at either side, each ledge being shorter than the one below it and accommodating' fewer bell-cranks. By this arrangement the upper ends of all of the bellcranks are brought substantially to a level with the pivotal ends of their associated radial arms 424:, from which the links 45 extend in substantially 'horizontal directions. The segment 51 is secured at its ends by screws 52 to arms 58, depending' from the under side of the top plate.

rl`he rear set of vertical bell-cranks 89 are pivoted in groups upon horizontal rods 54, mounted in slotted ledges or bearings 55, formed stepwise upon the rear face of the segment 51. The vertical arms of the bellcranks 46 are arrang'ed forwardly, and those of the bell-cranks 39 are arranged in rear of the segment 51, the horizontal arms et() of the cranks 89 extending` forwardly beneath said segment. The segment is given an upward and forward inclination, whereby the bell-cranks 39 and -l6 are given a substantially uniform separation horizontally from their associated radiating type-actuating' arms 87 and 41, so that the horizontal links of each set 88 and Ll5 may be of substantially uniform length. The key-lever links 41 and 48 may be made of graduated lengths to compensate for the graduated heights at which their attached bell-crank arms O and 47 are disposed. The links 48 are shorter than the links L11, and the latter pass between the key-levers 8.

Each link in the several sets is provided at each of its ends with a yielding keeper 56, as clearly shown in Fig'. 6, one end of each keeper being riveted to the body of the link at 57 and the other end whereof is perforated and fits over a laterally-projecting stud 58, provided upon the tip of the link. The keeper may be sprung' away from said stud 58, so as to enable the attachment or detachment of the link.

The lower end of each of the vertical links 41 and 48 is connected to its key-lever by means of a short arm 59, which is firmly secured to the level' by a single rivet 60 and is provided with a squared or parallel-sided hub portion 61, which may be caught by a suitable wrench and forced to turn slightly upon the rivet 60, thereby elevating' or depressing the arm 59, and hence adjusting' the vertical distance between the key-lever and its associated bell-crank arm 40 or 47. Thus any irregularities in the height of the key-levers may be corrected without disconnecting' the parts. The arm 59 lies flat against the side of the lever and projects rearwardly, the lever placement by the plate 71.

being' curved downwardly at 62, so as to clear the lower end of the link, which stands thereover.

A set of flat returning-springs 63 is provided for the upper key-levers and a set 64 for the lower key-levers, all of the springs having' at their forward ends pivoted upwardly-extending links 65, which are forked at 66 to engage notches 67, formed in the keylevers. At their rear ends the springs lit in horizontal grooves or seats 68, formed in transverse bars 69 and '70, the former resting upon the latter and the two being' secured together by screws 70. Vertical plates 71 and 72 are secured upon the rear and front edges, respectively, of said bars by screws 78. The front plate 72 is provided with two rows of square bearing-holes or seats 74, which register with the grooves 68, the ends of the springs being' inserted in the said holes and lying' within the grooves and curving upwardly attheir rear ends, as indicated at Fig. 1, and being' prevented from rearward dis- 'lhe tension of the springs may be adjusted by means of screws 75, which are threaded into lug's 76, projecting inwardly from the opposite walls of the base, and which bear up against lugs 77, projecting' forwardly from the opposite ends of the bar 69, this being' swiveled by shoulderscrews 78 between said walls, so that by turning the screws the entire housing for the spring's may be tipped so as either to increase or decrease the tension of all of the springs.

Just forwardly of the springs is arranged a transverse universal bar 79, which underlies the lower key-levers 7 and is hung, by means of links 80, upon forwardly-extending arms 81 of a dog-rocker 82, which is pivoted at 88 and carries both a feeding-dog 84C and a detentdog 85, said dogs cooperating' with the usual rack 86 for effecting' the letter-feeding movements of the platen-carriage. Each of the levers 8 in the upper tier is provided with a foot 87, which passes between the levers 7 and is adapted to bear upon the universal bar 7 9, as well as to engage its associated spring'- link 65.

Overlying' the forward portions of the upper key-levers 8 is a pad 88, against which the levers are normally pressed by the springs 68, while the lower key-levers 7 are pressed by the springs 64 against a similar pad 89, arranged just in rear of the fourth bank of keys, but sufliciently below the key-levers in the fifth bank to clear the latter. Each of the pads is supported by a transverse plate 90, having downwardly-directed guiding-lingers 91 for the key-levers.

In the body of each key-lever is formed an irregular open slot, which begins just in rear of the g'uide-comb 91 and extends first upwardly at 92, then rearwardly at 98, then diagonally upward at 94, and then horizon- IOO IIO

ently of the other.

tally rearwardly at.95 for a considerable distance, thus dividing the lever into two portions, whereof one may be moved independ- The upper portion 95 of the slot is arched, thus forming a thin and easily-sprung connection 96 between the key- Vbearing portion and the main portion of the sprung until the edges of the portion 93 of the slot touch, whereupon both the key portion and the main portion of the lever travel together for the remainder of the key-stroke. Owing to the resistance of the portion 96 to iiexure, there exists during the key-stroke a tendency upon the part of the main portion of the lever to resume its normal condition with reference to the key portion, thereby tending to accelerate the speed of the typebar or cause the latter to move proportionately faster than the key.

Beneath each of the upper and lower sets of key-levers is arranged atransverse padded stop 97, and the keys are provided with stoplugs 98 just over said pads. As will be seen at Fig. 4, the key is arrested by its stop 97 before the printing stroke of the type-bar is quite completed, so that the pressure of the linger is taken by said stop, while the momentum ofthe type-bar and connected parts is sufcient to enable the printing stroke to be completed and the type impressions made. During this final portion of the type-bar stroke the slot or gap in the key-lever opens a triiie wider than normal, the connecting portion 96 being caused to yield slightly downward. The immediate reaction of said portion 96 tends to restore or lift the main portion of the lever to its normal relationship displacement thereof.

In operation if a key be struck with moderate force the two parts of the key-lever move as if made in one piece, but if struck sharply the effects above described are produced. In case any key in the four front banks is struck its lever pulls down the link 4l, thus vibrating the vertical bell-crank 39 40 and through the link 38 swinging the radial bell-crank 37 36, which through the link 35 thrusts its associated type-bar up to the platen.

rear keys be struck, the type-bar movement If one of the is eected'through the key-lever 8, link 48, bell-crank 46 47, link 45, bell-crank 44 43, and link 42. In either case the universal bar 79 is forced down and by means of the hooks 8O vibrates the dog-rocker 82, so that upon the relief of the key from pressure and the return of the type-bar to normal position the carriage is fed a letter-space.

By dividing the lever into two portions and making one partially independent of the other it becomes possible for the key to be pressed downward somewhat in advance of the movement of the typebar and to complete its stroke before the type-bar has reached the printing-point. If the key reaches its stop considerably in advance of the type-bar, the finger is given time to come to rest and begin its upward stroke just before the type strikes. The stop is preferably timed to arrest the key when about two-thirds or more of the printing stroke of the type-bar has been made, so that while the finger is recovering from the stroke the type-bar may continue toward the printing-point aided by the reaction ofthe elastic portion 96 of the lever, thus efectually avoiding a double stroke or blurred impression, due as usual to a continued pressure upon the key, owing to the difficulty experienced by most operators in striking a staccato blow. Thus it will be seen that I have provided an elastic metal key-lever requiring a minimum amount of lateral space and on account of its light weight offering practically no resistance to the finger-touch. By reason of the elasticityT the key-stroke is cushioned loo at the beginning thereof, the key yielding at first in advance of the movement of its associated type-bar and connections, thus tending to even the force of impact between the finger and key throughout the downward stroke. 105

The key-stroke is also cushioned at its completion by means of the padded stop 97.

The plates 10() may be made in the form of a yoke closing down over the key-bearing portion, thus preventing the latter not only 11o from twisting, but also from becoming accidentally bent upward, so as to cause undue gaping of the irregular slot.

It will be observed that the levers in each tier carry a plurality of banks of keys and H5 are fulcrumed at their rear ends upon a plurality of transverse rods; that one tier is arranged over the other.; that one of the rods 10 is arranged rearwardly of and below the other and that the same is true of the rods 9; 120

that the levers 7, which carry keys at the front of the keyboard, project rearwardly beyond the rear ends of the upper levers 8; thatA the levers which carry forward keys in each tier are fulcrumed in rear of levers in the that the levers bearing the front bank of keys 13,0

are the longest and are fulcrumed upon the rearmost rod, while the shortest levers bear keys in the rearmost bank of the keyboard and are fulcrumed upon the foremost rod; that the keyboard comprises eight banks of keys; that the levers 8 in the upper tier com prise two sets, one set carrying' the rearmostbank of keys and being' fulcrumed upon the uppermost or forward rod 10 and the other set carrying' the next two forward banks of keys and being' fulcrumed upon the rear rod 10; that the levers in the lower tier 7 likewise comprise two sets, one set carrying the two lowest banks of keys and being' fulcrumed upon the lowermost or rear rod 9 and the other set carrying' the next two banks of keys and being' fulcrumed upon the next rod 9; that the rods 9 and l0 taken together form an upwardly and forwardly ascending' series having' suitable horizontal bearings upon an inclined frame 11, said bearings being' slotted vertically at 14 for receiving the rear ends of levers and also being slotted horizontally to receive said fulcrum-rods; that the levers in each tier diverge upwardly or downwardly according to the positions of their respective fulcrum-rods and are detachably engaged to the latter by means of notched slots extending longitudinally of the levers. It will also be seen that the pivots of the rearwardlystriking type-bars are arrang'ed in an arc which inclines rearwardly and downwardly; that the printing-center is preferably lower than the level of the platen-axis; that the seg'- ment 19 is arranged beneath the platen and is inclined rearwardly and downwardly; that two sets of type-bar hangers areattached to the forward or lower side of the segment and two sets of hangers are attached to the rear or upper side thereof and that the type ends of said type-bars have accordingly a staggering' arrangement or extend in curved rows across the machine; that connections are attached to the several type-bars between the pivots and types of the latter; that four sets of rearwardly-striking and radially-arranged type-bars lie side by side forwardly of and below the platen, the type-bars in three of the sets 22, 23, and 24, being' of substantially the same length and pivoted in three rows and the type-bars in the fourth set 21 being pivoted at a greater distance from the printing-center and terminating at their type ends forwardly of the other type-bars and the several sets of type-bars having an alternating or staggering arrangement, so as to secure clearance for both the types and the pivots, as well as for the connections; that key connections are attached to the type-bars 2Q forwardl of their pivots and extend downwardly therefrom, and that the typebars 23 are pivoted in rear of the type-bars 9,2 and arch forwardly over the latter, so as to clear said connections when the latter are operated to swing' the type-bars 2Q, to the printing-point.

flt will further be seen that pull-links 4t2 are connected to some of the type-bars and arranged upon one side of the system of tvpe-bar pivots,and tln'ust-links are connected to the other type-bars and arranged upon the other side ofsaid system of pivots,said pull-links and thrust-links having an alternating arrangement, one ty pe-bar, for instance,being connected to a pull-link,the next type-bar in thesystem being' connected to a thrust-link, the next to a pull-link, and so on, and that one set of key connections is arranged upon one side of the segment 19 and the other set of key connections 42 is arranged upon the other side of said segment. lt will also be noted that the type-bars are connected to a system of radially arrallged or converging bell-cranks or levers 36 37 and 43 t, the former being' directly connected by thrust-lin ks to their typebars and the latter being' directly connected by pull-links to their type-bars and the bellcranks or levers in one set alternating' with the bell-cranks or levers in the other set; that so long as these levers have a radial or converging arrangement corresponding with the radial arrangement of the type-bars it is not essential that each lever be made up of arms arranged at an angle to each other; that all of said radial bell-cranks or levers are pivoted upon a common fulcrum-rod 3?) and are arranged below the type-bar pivots; that the levers -13 i are arranged in rear ofthe type-bars and the bell-cranks 3G 2)? are arranged below the type-bars and that the arms 36 extend forwardly and the arms 43) upwardly from the pivot-rod. ltwill also be perceived thatone tier of key-bearing levers overlies the other, the levers in the upper tier S being connected to the forward type-bars 21 and 2Q and those in the lower tier 7 being connected to the rear type-bars 23 and 241; that said levers extend rearwardly beneath a system of bell-cranks working in vertical planes and mounted upon the frame 51 and connected to the radial bellcranks or levers mounted upon the segment 19 by two sets of links 3S and fk5; that said vertical bell-cranks are mounted in ascending series in accordance with the elevation of their connected radial bell-cranks or levers, the key-lever links atl and S being' accordingly of graduated lengths; that the vertical bell-cranks 6 LT are mounted forwardly of the vertical bell-cranks 39 0, the latter being also arranged at lower levels than the former and being connected to the lower tier of keylevers and all of said vertical bell-cranks being pivoted upon a downwardly and rearwardly inclined frame 51, arranged forwardly of the segment 19; that the arms 40 of the rear or lower set of vertical bell-cranks extend forwardly beneath the lower edge of said frame 51; that said frame or support has formed upon its front and rear faces bearing's 50 and 55, having a stepwise arrangement, and that the vertical bell-cranks are pivoted in groups upon said bearings and 55, a large number of bell-cranks being grouped in a transverse line at the middle lower portion of each of the back and front sides of the frame and Athe remainder of the bell-cranks being' grouped in a succession of shorter transverse lines at successively higher elevations at the sides of the system. It will further be seen that I have combined a series of type-operating arms, a series of levers, and a series of links connecting said arms to said levers, each of said links having upon each of its ends a yielding keeper 56, one end whereof is perforated and lits over a laterally-projecting stud 58, provided upon the tip of the link, whereby the latter is detachably pivoted at each end to its associated arm and lever; that the levers 7 and 8 are provided with short arms 59, whereby said levers are connected to a series of type-operating arms, each of said arms 59 being firmly secured by a single rivet `upon the body of its lever and being also provided with a parallel-sided portion 61, which is adapted to be engaged by a suitable tool, -whereby said short arm may be forced to turn upon its rivet, thereby causing a relative adjustment between its associated lever and type-operating arm, and that the links 4l and 48 are directly attached to said short arms 59. It will also be observed that the set of springs 64: is arranged above the set 63 and that the springs in both sets extend longitudinally of the key-levers 7 and 8 and are fixed upon a single supporting device which extends transversely of the machine and are also detachably connected by forked thrust-links v65 to the key-levers; that each of the transverse bars 69 and 7 0 is provided with seats for the springs; that the plate 7l prevents rearward displacement of the springs, the latter abutting against said plate at their rear ends, and that by means of the screw 75 the spring-support may be rocked upon its bearings, so as to adjust the tension of the springs. It will further be observed that the key-carrying portion of each lever 7 and 8 is capable of bodily movement independently of the remaining portion, said portions being joined by an integral. yielding or ficxibl'e neck 96; that one portion of the lever bears the key and that the other portion is connected to the type-bar; that the elastic construction 96 is located between the ends of the key-lever, whereby the forward or key portion is enabled to yield relatively to the rear or type-bar-operating portion; that the relatively yielding movement of said portions is limited to the width of the slot or gap in the lever; that upon said gap being' closed at the depression of the key the two portions of the lever move together as one piece, so as to cause the typebar to swing to the printing-point; that the stop 97 is provided for the key-bearing portion of the lever; that upon the arrest of thev key by said stop the movement of the typebar is aided by the resiliency of the yielding connection 96 between the two lever portions; that the keys are arrested ld uring the printing strokes of the type-bars and before the latter strike the platen-g that the universalbar and carriage-escapement devices are operated by the portions of the levers 7 and 8 which are connected to the type-bars; that the adjacent ends of the lever-sections overlap and lie edge to edge and are connected by a yoke 100, iixed upon the lower section and embracing the upper section; that the finger-key portion of the lever may move independently 'of the other portion when the key is struck Y sharply, so as to relieve the force of the blow upon the finger, while at the same time the lever as a whole may vibrate upon its rear fulcrum to cause the type-bar to swing t0- ward the platen, and that the irregular slot in the forward portion of the key-lever is in the direction of the length of the lever. It will also be seen that I have provided a visihangers to which the type-bars or levers are pivoted are applied alternately to opposite faces of the segment or segmental support and are so arranged that they have an overlapof the machine.

My improvements may also be applied to under-strike and top-strike machines, and many variations may be made within the scope of the invention. Portions of the improvements may be used without others.
