Specification of Letters Patent.

Patented July 7, 1908.

Application filed June 21. 1902. Serial No. 112.566.

a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new anduseful Improvements in Typographic Machines, of which the following is a specification.

This invention relates to typographic niachines and more especially to those features thereof which pertain to the means for supportingthe impression devices and for bringing them selectively to the working point of the machine.

The present improvements have for an object to provide an impression-device carrier, whether the impression devices be in the natureof dies, or of types or of other instrumentalit-ies employed in marking or subjecting a surface to a working, which carrier is of simple construction and possesses a capacity for supporting a large number of such devices; and to combine with such carrier mechanism whereby any one of the devices so supported may he brought at will to the working point and there caused to operate.

A typograplnc machine embodying 'my present improvements comprises a carrier upon which are mounted proper impression devices, any one of which will, in general, be brought to the working point of the machine as a result of a movement in two directions; asordinarilyconstructed, the impression device carrier will be susceptible of an angular movement, and a movement in some other direction, for the. purpose of locating the chosen or selected impression device.

- I n carrying my present improvements into practice, the impression dev ces will ordinarily be mounted upon a rotarily ad ustable carrier, which in addition to, its angular movement of ad ustment, possesses a capacity of being tilted to bring any impression device into the horizontal plane of the working point, that is that plane in which the working point is located and which is transverse to the axis of said angular movement.

In its most convenient form the impression device carrier, for the pur ose of enabling the various motions liereinbe ore adverted to, to

be imparted to it, willbe connected to the driving member of the machine bya so-called universal joint, whereby the carrier may not only'be adjusted through different angles, but

position in which any one of the impression devices in any one of a number of rows thereof-extending in a line with the axis of angular movement, may belorought in proper juxtaposition to the working point.

Such a carrier as hereinbefore described, and ossessing the capacity for such combine movementunder the control of a selective mechanism and constituting a typographic mechanism, embodyingmy present invention will 'now be described with the aid of the accompanying drawing in which Figure 1 is a central vertical section taken from front'to rear of the machine, parts, however,being represented in elevation, and the various operating members being shown in a relative position corresponding to that assumed by them when not in the act of being adjusted, or in the act of making an impression. Fig. 2 is a view similarto Fig. l but shows the parts in a position which they assume upon the operation of a. key of the selective mechanism, and while in the act of making an im ression. Fig. 3 is a section on the plane of t e line 3-3 in Fig. 2, looking toward the rear of the machine, certain of the parts being omitted. Fig. 4 is a plan view, the upper part of the inclosing case thereof being removed, except at the front or key-board portion thereof. Fig. 5 is a perspective view of the rock-frame by which the impression device carrier may be tilted to bring an impression device at one side or the other of thework-ing point into the plane of that point and into'propcr juxtaposition thereto. Fig. 6 is a plan view of the impression device carrier.

' Similar characters of reference designate like parts in all the figures.

From what has already been explained, it is apparent that the present invention is applica le generally to typograph piachines irrespective of the particular nature of impression devices employed; that is to say, it may be utilizedin connection with typewriting machines, 1118.0llilit8f0l making types or lilies of type, matrix making machines, &c., and while I have for the purpose of illustration, set forth in the drawm s accompanying the present specification, fire invention as ap.- plied to a machine of the typewriter class, such particular illustration and the particular description-hereinafter set forth, is not therefore, to be 'eonstrued .tobeby way of limitation or'restriction of the invention'to use in such particular species of; machine. Moreover in the manufacture and assembling of the various parts'to form a complete and practical operative machine, it: is contemp ated that such a degree of engineering 5 andconstructive skill shall beemployed as toproduce a proportion of parts and character of connections adequate to transmit the necessary forces and to create the necessary rigidity and precision. The exercise of such skill on the part of the designerv and constructor to meet various conditions may,

therefore, result in a mechanism the details of-construction of which differ from those illustrated in the drawings hereto attached so, a [I 1 The im ression device carrier or turret is various operative and other parts 0 'struction of this-maybe varied within wide which are accordingly to be taken in the.

sense of being illustrative only of these special matters.

limits and adapted to su port various parts of the -machine, depen ent upon circumstances and the particular application made of the invention. v.

designate 'ina general way by D, and, as

above stated, it is capable of an an ular v Jmovement which, 1n this instance, is a out l as a fixed axis defined by the axis of a rotary shaft -2, suitably mounted in the casing of :the machine or fixtures of the casing, one of theQbe'arings in the particular mounting 'showni being in-a cross bar 7. The im ress1on device carrier is susceptible not o, y to an an ular movement, about the aforesaid shaft, ut it isso mounted and connected tothis shaft, as to permit it to be tilted with reference to the axis of the shaft. A convenient. construction for enabling such movement to be glvento the carr er com rises some form of UmVGI'Sal'JOHIt, and wh 1f carrier will ordinarily be of such-configuration andform as-to necessitate'aminimum I amount of material'therei'n inorder to render "-Qthe same aslight' as may be, it this;'.-i n{ stance. provided interiorly, with a pairofg cross -walls 3, 3 in which are formed bearings if for trunnions or pivot- studs 4, 4 extending '55 y from a member or; block 5'; locatedjbetween the walls. To complete theconnection' beftiweejn the carrier and the driving-shaft 2, so as toenable the carrier to be tiltable in any a direction. relatively to the driving: shaft, the carrier iscapable' of turning-about anaxis extending at substantially right angles to the .ax isigliefined .by the pivot-studs A, 1; in this .instancesuch pivotal connection-is consti tuted by a pair of trunnions or pivot-studs- 4,' which extend-from block 5 ;an'd arejoun e the face of w On the exterior of the 'carrierthe impres- I sion devices are mounted These are of suitable form and construction, dependent ;of course, to some extent, upon the particular style of machine to which the universally adjustable carrier is applied. As the present embodiment is that of a typewriter, such impression devices consist in this instance of proper types, designated in a general way by d which may be mounted upon the carrier in any proper way. As the carrier is susceptible of a nutatory motion with reference to the axis, the exterior surface of the carrier may conform substantially to a when of 'the exterior surface or periphery of a sphere.

The carrier may likewise e made in parts for convenience in assembling and secured together as by pins or bolts d, d.

In the particular embodiment disclosed in the drawings attached to the present specification, the types are disposed in three planes transverse to the axis of the carrier, while the types in one plane arewith relation to those inthe other disposed in line with the axis of the carrier. There will be, there, fore, under such conditions, as many differ ent stations or positions of angular adjustment of the carrier eflected through the angular movement of the shaft 2, as there are types in any one plane, while for each of such angular adjustments (assuming that there are the same number-of types in each plane) 'there will.be three separate positions of the carrier corresponding to the particular one of the three types of an axial row which is to be brought in juxtaposition to the fixed Working point of the machine. For

the purpose of enabling any one of these last adjustments to be efiectedthat is to say to permitithe carrier to be tilted to; bring any one of the three types of an axial line thereof 0 posite the working point of the machine, have in this instanceprovided a rock-frame which engages with the upper and lower radial surface. of the carrier and which when actuated serves to tilt the carrier and bring the same. into its proper tiltedposition, This rock-frame is illustrated more particularly in Fig. 5 and the same is designated by Its side, members 6,! e, .are pivoted "to. uprights 6' "erected upon the cross-bar 7,.extending -gfrom side to side of" the casing and in which the aforesaid drivingshaft. 2 is journaled. The angular position of the rock-frame. E:is-=contro1led from the selective mechanism hereinafter to be, de-

scribed, through a longitudinally reciproca 'blef rod-8, whose upper-endis connecte'djby a link 8. with a'pivot-pin s"- mounted-betw nthe ears 8/", 8 extending from the aforesaid rock-frame E. The latter is provided", with an-oplening e. the upper and loweigsur-j 'ch constitute ,the surfaces; with" whichlthe radial surfaces of the 'cairier I) engage when the parts'are assembled; such bearing surfaces may be formed b'y'b'earing" stripsf e, 6f? Referring now more especiallyjto the" selective mechanism, whereby: anyf'chosen die on the carrier is slectedjfor juxtaposie tion to the workin point, thi's 'gn'r'eohanisnt comprises the usua or any approvedicom st'ruction. and arrangement .of key levers.- Each'lever in this instance is designated'by K and-provided at its end adjacent to the front of, the machine with afush rod k which .extends upwardly throng ,anjaperturein the casing and is surmounted by a properly eharactered finger piece k. In the simplespecies of mechanism set forth in the drawings each key' lever serves to control the operative position of a stopin selector,

which in turn, when a suitable evice on the shaft-2 is brought into cooperative relation with it, serves to stop the motion of that shaft with the shaft in a position such that that axial. row-of types inwhich thetype' to thekey depressed is .in

corresponding elude 1s'1n me w th the working olnt of To enable'this resu tto be.

the machine. effected, the shaft 2 is, in this instance, frictionally driven, a driving pulley 9 being loosely mounted upon the shaft and being adapted to be continuously driven from adriving belt 10, actuated from some suitable source of power (not shown); Guide- pulleys 11, 11 serve in the organization disclosed, to properly guide the moving belt into the I there is shown an adjusting nut 13, and a check-nut 13 engaging with a threaded portion of the shaft while the thrust or reaction is takenby a collar 14, upon the o )posite side of the driving pulley ant rigid wit the shaft.

In the present organization the devices whose positions are controlled by the keys are in the nature of stoppins, each designated in a general way by F, and disposed concentrically about the axis of the shaft 2, the pins working in openings in a stop-pin holder consisting of a cross piece 15 extending from side to side of the casing of the machine and having a central opening 15 through which the aforesaid shaft .2 extends. The normal or inoperative position of each of these stop-pins correspomls to its lowermost position (the machine being assembled as indicated in Fig.2) a rr-seating spriug lfi cncirclii'ig each pin and being interposed under tension between the lower surface of the stop-pin holder, and a collar or flange 16, on tlu-.'stop-pin. This spring tends to move its encircled pin to its normal position while 'sto pus ed upward'by virtue of the actuation of :nection with the printing mechanism.

its excess downward movement is vrevented ."by a collar 16 on the pin whici engages with the upper surface of the stop-pin holder.

one of the I A membercoo erative with any have been -pins when t estop-pin shal the corresponding key is mounted upon the shaft 2, and designated by 19, will be referred to more in detail hereinafter in c loln- 1e several key-levers K are in .this instance suitably fulcrumed intermediate their ends and-they are of such shape and formation as to bring their-inner ends under the heads or collars 16 of the respective stop-pins F which the lovers are designed to actuate. In this instance, since the impression devices are disposed in three transverse lanes the levers willbe disposed in sets of t ree, each lever in a set beln adapted to elevatethe same stop-pin, as t 1e other levers in the set and thus serving to bring the same axial line of type in line with the working point of the machine' whichever lever of the set is operated.. Each lever is provided in the usual manner with some form of elevating spring 17 secured at one end to a fixed portion of the machine, and bearing at the opposite end against the under side of the lever. As

before stated each lever is fulcrumed inter- .mediate its ends, in this instance to respectiveears '18 extending from the plate or fixture 19 secured to the machine casing, the relationbetween the lengths of those portions of each lever upon op osite s des of this fulcrum point, being such t rat the amount of movement imparted to the corresponding stop-pinshall for all the stop-pins be substantially equal for a fixed amount of depression of the outer end of the levers.

Referring now to the means illustrated for shifting the aforesaid longitudinally recip-' rocable bar 8, to thereby effect the'proper tiltin of the impression device carrier, there is int icated a rock-shaft 20 journaled in bearings in the side frames of the machine casing, from which shaft extend arms 20, 20, whose outer or free ends are connected by a cross-bar 21, disposed beneath the series of key-levers. Attached to the ,said rock-shaft 20, and extending rcarwardly' of the machine is an arm 22, furca'ted to pass the shaft 2 and having a cross-pin 22 located under and contacting with the lower surface of a head 22 on the aforesaid bar 8. .In the normal position of the parts the rearward end of the arm 22 is held depressed, being urged to this position by a spring 24 under tension, and inserted between the lower surface of the aforesaid stop-pin holder15,-through which the bar extends, and the shoulder formed by .shown in Fig. 1 in which the carrier is tilted to such an extent as to bring that impression device in the upper transverse row thereof which is nearest to theprinting point, in proper juxtaposition thereto, and hence when any one of those key-levers referable to the types in this upper row, is actuated,.

. no movement will be imparted to thebar 8 when, however, a lever referable to the inter: mediate transverse row of impression devices is operated, the motion imparted to the bar 8 is such as to tilt the carrier a proper. amount to bring that impression device of the intermediate-row oppositethe printing point, which by the actuation of the key has been brought in line therewith, this movement being effected as the result of the contact of a projection or boss on the keylever with the cross-bar 21, connecting the arms 20 of the rock-shaft 20. Similarly, when a key lever is actuated which is refer- I able to the lower transverse row of impression devices a somewhat deeper extension or boss 25 upon the lever, will, by reason of its earlier contact with the said cross-bar 2'1,

efiect an amount of tilting of the carrier sufficient to bring the selected impression device in uxtaposition to the printing polnt.

No motion of the. hammer can ensue 'until the catch 35"is released from the catch" 34 and this release and the motion of the driving shaft 2. A spring 4 constantly urges this sleeve .u ward to its 1 hammer should beefiected whenithe selected imp ession device shall have been brought in juxtaposition to the printingpointto make an impression. For effecting this release, thefinger 19, cooperative with an a preachbeen described 'as..' -moimted upon the shaft 2, is secured to an'oscillatablerod 41mounted ina which rod extends an'a'rm 43, having a. fur

This piii 'is ada ted to slide through an opening in'thestri er arm While the spring after compression urges the afore-' of the aforesaid arms 46.

said striker arm upward and is effective to return the arm and the parts connected thereto to their normal position, this action being assisted by a spring 54 secured to a fixed portion of the machine and bearing against one It is to be noted at this point that -the com re'ssion of the s ring 52 does not become e ective to bring. t eimpact face-of the hammer through the openingin the paper guide 30 to make an impression until the impression device shall ave assumed its proper position with relation to the-.workingpoint of the machine,

. that is to say the release of the catches 34,

does not occur until after the-spring 52 has been compressed, the impression device carrier properly tilted and the finger 19 has contacted with the raised stop pin.

The slide 26 already referred to, constitutes the carriage of the machineiand for 'i-mparting astep-by-step or intermittent motion to it corresponding to the letter feed of the paper or like substance some suitable mechanism will ordinarily be provided, the

form thereof illustrated comprising an escapement device operated from the aforesaid link or connecting rod 49 which at the rearward end of the machine is pivotally connected to an arm extending from the escapement rocker shaft 55. The escapement .in this instance comprises two parts, a feed I part 56 movable relatively to the other part 57. Each of these parts is in the nature of a tooth adapted to engage with the teeth of a rack 58- formed rigid with the aforesaid slide 26. The feed tooth 57 of the escapement is spring pressed in one direction in the usual manner but the'force of the spring is sufficiently weak to be overcome by the force of the usual spring which serves to urge the slide 26 in one direction thereby effecting the feed movement of the slide,

When the outer end of a key lever is depressed, the tooth 56 of the escapement is a shifted out of engagement with the teeth of the rack and "the feed tooth shifted into engagement therewith. At the instant of release of the tooth 56 from the rack, the spring of the slide shifts the latter'one or more teeth, and upon the return of the keylever to its normal position, the tooth 56 reengaging with the rack will permit the feed tooth 57 to return ready to rengage with the rack upon the next actuation of a key lever. A typographic machine organized in the foregoing manner operates substantially in the .following manner: Assuming the shaft 2' to be in constant rotation from the driving belt 10, the depression of any key-lever K will raise the stop-pin F with which its inner end is in contact and bring its up e'r' end into the path of movement traverse by the cooperating finger 19 mounted upon the shaft.

"the actuated lever should happen to be one whose character is referable to an impresthe plane of the ahnement of the .Sion device in the lowermost transverse row thereof, the projection or boss 25 thereon impinging against the cross-bar 21 causes the upward tilting of the arm 22 and the conseuent elevationof the rod 8, shifting through t e connections already described, the rock frame E and effecting the ultimate location of the chosen impression device of the lowerrnost row in juxtaposition 'to the working point of the machine. Coin'cidently with the actuation of a key lever the link'49 is drawn toward the front, causing the slide 26 to feed and the spring 52 to be compressed. When the projected-stop-pin shall have contacted with the stop finger 19, the shaft 2 is brought to rest a an simultaneously therewith the sleeve39 is actuated releasing the hammer 33 which thereupon is thrown forward by the compressed spring 52 to make an impression. This action substantially is repeated each time a key lever is depressed.
