P the im- Patented June d, 1907,

The invention embodies, also, in combination, with the foregoing, a selective mechanism, whereby a particular type or die upon all-others, the operation of any type or die being therefore under control.

A machine embodying the various features of this invention will be described in the following specification with the aid of the accompanying drawings, in which Figure 1 1s a plan view of such a machine. Fig. 2 is a. side elevation thereof.

Fig- 17'- is a similar view of the 'impressor shown in Fig. 14, the same being detached. Fig. 18 is a similar view of the immachine, but the invention is not limited, it will be understood, to such particular embodiment, it being applicable in. whole or in part as respects its various features to typographic-machines in general or machines in which an impression device is designed to operate upon or affect a certain surface.

The impression devices of this machine are rotary or rolling inlpl'cssors, consisting of one or more main parts or carriers each comprising a plurality of sections upon which are mounted one or more impression types or dies. These parts are disposed, according to the present invention, when in their normal.

or inoperative positions, in such relation to a fixed plane (hereinafter referred to as the o erative plane) as to be shiftable axially t ereinto, and if a main carrier embodying a set comprising three carrier sections is employed, as shown in the drawings attached to this specification, a carrier-section may be located on each side of said plane while a third is normally in that plane. While three carrier-sections are shown as forming a set, it is evident that this number may be increased or diminished ,without departing from the spirit of the invention. All the carrier-sections in a set are shifted axially to bring any particular one of such sections normally at theside into the fixed or operative plane, (see lines PP, in Figs; 6, 7, 8, and 9). For this pur ose they may be conveniently affixed to s afts which extend on one side of the operative plane and are fitted the one shaft to rotate within the other;

I Each main carrier is adapted to have both a movement in a closed circuit ororbital path, and, at times, a rotary motion about its own axis. In the particular instance illustrated, this closed circuit or orbital motion is that of revolution about an axis exterior tothe carrier, and for the purpose of conveniently enabling this double motion to be attained the shafts 4, 5, and 6 carrying the

sections

1, 2, and 3, respectively, of a set are shown mounted in a turret or rotary carrier 6 whichmaybe rotated by the shaft 7 through the medium of a pulley or bandwheel 8"from a'convenient source of power. The bearings of this shaft 7 are supported by a suitable fixture or fixtures which, in the present instance, are constituted by the protecting casing 9 inclosing the mechanism.

Such a number of sets of carrier-seciions as are desired, within the capacity of the turret, are disposed thereon, being allixed to suitable sets of shafts. each set may be journaled in an arm 17 extend ing from and secured to the shaft 7, and the inmost shaft 5 at one end in an arm 17".also extending from and secured to the shaft 7. If, now, the intermediate shaft 4 of the set is journaled on the inmost shaft 5 and extended toward the operative planein the space between the outer and inmost shafts, the

The exterior shaft 6 in shafts afford mutual support for each other. Theseveral arms 17 and 17 extending from and secured to the shaft 7 in conjunction with the latter may be regardedas forming the turret 6 7 Each set of associated shafts 4, 5, and 6 is adapted to have an independent rotary motion imparted to each of its component shafts in addition to the orbital motion which the set may have by virtue of the rotation of the turret 6 and for this purpose to each shaft there may be secured a gear or toothed wheel 18 engaging at times with a driver, in this case an internal gear-wheel 19. There is a gear-wheel .19 for the series of inmost shafts 5, another for the series of intermediate shafts 4, and another for the series of outer or exterior shafts 6. Each internal gear 19 is shown as being secured to the casing 9, and it affords a positive means when a gear-wheel 18 is engaged with it for effecting a rotation of the gear-wheel.

The endwise or axial movement of each shaft 4 and 6 in each set for bringing the corv responding carrier-se -lions into and withdrawing it from the operative plane is utilized for engaging the gear-wheel 18 on the shaft with and disengaging it from the corresponding driver 19. To effect this endwise mo vement in one dirccti on there may be combined, as shown in the present instance, with each series of exterior shafts 6 and each se ries of'inmost shafts 5 an actuating member or cam 20, with which there is adapted to cooperate a coacting member or cam-arm 21 on each shaft in the corresponding series for shifting the shaft toward and bringing the-corresponding carrier-section into the operative plane. it will .be manifest that since the rarrier-sectirms supported by oneof the mentioued series of these shafts, in the illustrated and described organization, lie when in their normal positions upon one side of the operative plane and the carrier-sections sumiortcd by the other series of shafts lie upon the other side of the operative plane, that the two'series of shafts move in opposite directions in approaching the operative plane. Hence the cams 20 for the two series will face in opposite directions. For returning the shafts in the two series there may be an actuating member or cam 22, one for each'series.

with which is adapted to co-operate a com-iing member or cam-arm 23, projecting from each shaft which accomplishes the shifting of a shaft biwlnvard and the withdrawal of the corresponding carriensectionfrom said plane. These cams?! for the two series of shafts also, it will be understood, are oppositely facing. Each arm in one of these two series of cam-anus 21 and 23 here shown to be 438111- arms 21, may have its operative surface arranged at the end of a flexible or spring-like strip, which method of supporting the operative portion will tend to suppress theviolence of the shock when the contact.

When the carrier-sections 'on any set of parts come in associated shafts are in their normal or'inoperative positions the intermediate carriersection attached to the intermediate shaft 4 lies in the operative plane, as here organized and asshown in. Figs. 3 and 6. Hence it is i not necessary to shift the intermediate car-' lengthwise- "rier-section of a set axially when it is desired to set it in rotation, and in fact such a shifting, it is evident, would prevent its operation at the designed point in the operative plane. To effect the rotation of any intermediate shaft 4 andthereby its attached section 2, the gear-wheel 18, for this purpose, is shown mounted upon a. sleeve movable along the. intermediate shaft but fixed thereto so .easethere may be combined with,the. series of sleeves "an actuating member or 'cam 20,

withwhich is adapted to coeoperate' a coacting memberor cam-arm 21 extending "from each sleeve and similar to the cam and camarms 20 and 21 already described, although Tss- -.are',notherein shown as beingsupported theioperative portions .of the cam-arms 21 upon, flexible or' spring-like strips. For the several sleeves-iirthe'opposite direction there may be an factuat'. memberor cam 22 with which isadapt'e to cooperate a coacting member or cam-arm 23 oneacli sleeve similar to the cam and cam- 15131 22 and 23 already described.

For holding-each sleeve 25 in a position to which it may be adjusted axially, and to prevent its axial movement when either the exterior shaft 6 orlthe inmost shaft 5 of the corresponding set is shiftedto bring its attachedcarrier-section into the operative plane,'there is shown a lever 31 pivoted at 32 to a 'boss 33upon the shaft 7 and pressed 2 downward by a spring 33 against a raised yer from the side to the top .vice versa, but not preventing it when su-fiiportion or rib 34 on the sleeve. This lever 31 and rib 34 are preferably formed to engage witheach other that their coaction will be such as to resist the displacement of the leof the rib, and,

cient forceis exerted through the operation of the. shifting cams 20 and 22 to e act the transfer.

4 The-cams 2O and-22 for each series of exterior inmost shafts and theicams 20 and 22 for the series of sleeves 25 may be attached to the casing 9, and are located in the-proper positions to co-ope'ratewith their respective arms, While the distance each causes a shaft or sleeve to move axially is not sufficient to carry the other arm of that shaft or sleeve which coacts with the other cam be ond the point where contact of this "arm wil take place with its cam when the shaft or sleeve has been swung around to render the arm operative.

- The two cams 20 and 22 for each series of shafts and the cams 2'0'iand 22 for the series diametrically, opposite sides .of'the circle in which the operative ends of their cam-arms move, while each cam is of. a length suflicient to insure; the contact of the coacting arm with it as a shaft or sleeve rotates about .its

own axis and revolves about the axis of the of sleeves 25 are arranged substantially on turret. As a result a movement of the shaft or sleeve to jand fro for each rotation of the turret 6 is produced.

' For each series of shafts 4, 5, and 6 there will'be provided some form of device for resisting, to a considerable degree, anv axial movement of the set for the pur ose of holdthe set of shafts in an axia .position to 1n 'wldich they may be shifted. For instance, a

spring-pressed detent 101 may be urged into either one of three grooves 102, 103, 104, corre 'sponding to the axialpositions of the shafts and formed in a disk 105 attached to one of the shafts of a-set. If the sides of these grooves are made slanting and the detent corresponds in form the pressure inward of thedetent will cause a degree of end thrust in the shaft tending. to complete .the operation of the shifting cams .20 and 22. A' collar afilxed to each inte'rmediateshaft 4 is shown for preventing the axial movement of the exterior shaftfialong the intermediate shaft While the corresponding movement of the latter shaft with respect to its inmost shaft 5 may be prevented by similar means.

, "Some "form,;of' a ping the rotation o a shaft in a determinate angular position when itsgear-wheel 18 has been thrown out of en agement with its driving-gear 1 9 I will also fprecision -brake for stope provided. The 1 'device shown in the present instance comprises for each intermediate shaft an elastic finger 27 secured to the boss 33 and extending across the path and tending to'retard the, revolution of the. pins'26 before'mentioned. A similar device-1s employedv for the other shafts, and consists of asimilar elastic finger 27 for each exterior shaft-Gprojecting from the shaft 7 and extending into and tending to retard the revolution of pins 26' extending from a flange 26 projecting radially from shaft 7 and a. similar elastic finger 27 similarly related to pins 26 projecting radially from a flange 26 upon eac inmost shaft 5.

For initiating the rotary movement of the individual shafts 4, 5, and 6 and sleeve 25 for the purpose of turning the arm 21m 21 into a position in which it may coact with its proper cam each shaft is provided with a startingarm 28 operating substantially in the manner set forth in Patents Nos. 431,371 and 57 3,620 granted to me on April 16, 1889, and December 22, 1896, respectively, which maybe consulted for a detailed description of its con struction and mode of operation A starting-arm 28 on each shaft or sleeve maybe arranged in a different transverse plane to that of the starting-arm on any other for a purpose that will be explained later.

Referring now to certain selective devices whereby a particular sl'iaft may be set in retation and the amount of such rotation that shall occur up to a fixed point where an impression device is to operate be under con'-' trol, these results may be attained by the employment ofa series of latch mechanisms, the tripping of anyone of which will cause a reciprocating latch or bolt to protrude into the path of a revolving starting-arm which engages therewith and turns the shaft in its Y bearing, itself resetting the latch. in the manher set fort'h in the aforesaid patents.

An suitable mechanism of this character may bh employed or that particular organization thereof to be described.

. Each latcl. mechanism as herein shown is operated by means of aspring-returned rocklever 29,. actuated by pressure upon a key 29* at its outer end. A number of these rock-levers 29 is shown corresponding in number to the types or dies uponthe im pressors. They may all be fulcrumed at the rear of the casing 9, for instance, by a rod 150, and may each have a push-rod. 30 extending upward through an opening at the front of the casing and provided at its'top with a finger-piece or key 29.

There will be as many latches or bolts in the latch mechanisms designed to actuate any single shaft supported on the turret 6" as there are types or dies upon the impressor affixed to that particular shaft. Furthermore these latches are arranged at ,different distances from the point at which the types or dies operate or impression is made for the purposeof initiating the rotary movement of the shaft at different distances from said fixed point.

The latch mechanisms for initiating the rotary movements of any single shaft will all be located in the same plane in which the starting-arm 28 thereon swings, while this latter is made of a width sufhcient to preelude its passing to one side free of the latch mechanism despitethe axial shifting of the shaft to which the arm is attached by the ac tion'o'f the

cam

20, or 20.

i I In Fig. 3 there are shown twelve separate latches substantially in the same plane, but

i of course this number may-be increased or diminished according to the numberof types have. Each series of latches'for operating any one shaft is conveniently located in a latch frame 32 so formed and located as to therein to be arranged circularly or concentrically with reference to the axis of the turret 6 Each latch mechanism comprises a bolt or latch 33fitted to slide through suitable openings in the latch frame toward and away from the turret axis. Each latch, in the present instance, is held in its inoperative or retracted position by anotch 34 there on which fits overthe edge of an opening in the latch frame and prevents the latch from being thrown inward under the tension of a spring 35, by reason of the contact of the side of this notch with the shoulder 35 in the latch-frame opening. A spring 36 normally holds this notch 34 pressed against the shoulder 35" of the opening in the frame, but the opening is wide enough to permit a sufficient lateral movement of a latch when the notch is pressed away from the shoulder for a latch to clear the latter. Suitable intermediate devices are inserted between each rock-lever 29 and its corresponding latch or bolt As shown in Fig. 4, some of these intermediate devices comprise each an angle-lever 37 pivoted to a stud 37*, extending from a llangeSS of the latch frame 32, one of the arms of the angle-lever being connected with its corresponding rock-lever 29 by a link 38, while the other arm of said angle-lever made in the form of a finger 39 which passes over a projecting toe 39 on the latch. A downwardqnovement of afinger presses the notch 34 away from the shoulder 35" and permits the corresponding latch to be thrown inward. Others of the latch mechanisms are shown as constructed to be each tripped by means of a finger 40, pivoted or otherwise connected to a rock-lever 29, while it is properly guided by means of pins l()l0 on opposite sides thereof, and has its angularlyextending upper end 40" lying above the extremity of the latch.

The various rock-levers 29, angle-levers 37, links 38", and fingers 40, concernedin the actuation of any one starting-arm are made of such forms and dimensions aswill permit the motions of the. several rock-leverswhen lying side by side as shown. to be transmitted and serve tooperate thelatches or bolts ar ranged in the plane of thatstarting-arm.

The several latch fra1nes'32 for supporting the several sets of latch mechanisms may be conveniently held in placelupon a rod 42, extending lengthwise of the machine.

A step-by-step motion or a motion of any other character to properly feed the material whose surface is to be impressed or acted upon may. be imparted to such material by any suitable means or ,that herein shown, which is designed to accomplish a stcpdrvor dies it is desired that each impressor shall 1 step or intermittent movement. Supported permit the inner ends of the latches or bolts arm 46 may desired, as shown in to this particular position. while the rock-shaft 48 is in t mined position and is not being -tact with and be moved by a shoulder upon a feed wheel or disk for the purpose of accompl shing this feed movement. Normally, (assuming that the turret 6 is 'rotatin the operative plane to eiiect an Impression, andt at thegear-wheel 18 on each sleeve 25 is out of its engaging position as shown in Fig. 3) there is no contact of this pin 47 with a shoulder upon afeed wheel or disk, but when-a carrier-section has'been shifted into the operative plane or the gear-wheel on a sleeve into engagement contact willbe made sometime during the orbital and rotary movement of the carrier-section between a shoulder upon a correspondingfeedwheel or disk and a pin or projection-47.

There is a swin lever and a floatingarm 46 supplied wit for each of the series of carrier-sections, or, in other words, each series of-inmost, intermediate and exterior shafts. These swinging levers 45 are afiixed to-a rock-shaft 48 mounted in suitable bearings, which may be supported by the casing 9.- The rotation of the rock-shaft 48 in. one direction past a predetermined point is prevented by a stop, 13, while a spring 51 constantly ur es the shaft ormalll or pre eterturned in its y a floatingbearing, the direction-taken- Fig. 4, where it is seen po nting on that side of the turret axis which 1 1s moving toward itwhen the turret is rotat- The floating-arm 46, however, may not in 05y be moved forward in the manner pomted out below to turn the rock-shaft 48, but

tion relative to 4s may also be deflected from its normal posithe lever 45, being designed to return to such normal position when free to do so. To bring about this return it may be provided withan elastic finger 52 confined between stops 52 52".' I a The feed disks or wheels mentioned as oooperating with the pins 47 may each consist of a separate and independent disk attached to each shaft in the series of exterior and inmost shafts and the sleeves 25on, the intermediate shafts 4, or the gear-wheel 18 upon each shaft and sleeve may perform the function of such feed-disk as herein illustrated. The shoulder stated as coacting with a pin 47 maybe formed as shown by notching the radial face of each gear-Wheel 1ndicated generally by 53, or such shoulder may be formed by the bottom of the gear-wheel tooth which for this pu pose may be regarded as forming a notch.

bach floating-M11146 is to that set of feed-Wheels, or, as herein s own, gear-wheels 18, with which it is designed to but i that no carrier-section has been shifte into a pin or projection 47 be, if a feed before impression 1s,

arranged ad'aoent co-opeiate, and upon that side of the gear 4 tact of the pin 47 takes place with a shoulder on the feed or ear wheel;

The lateral reedom of movement of each pm 47 permits it to readily seat itself in the ottoin of a notch 53, whereupon further orbital and rotary movement of the earwheel 18 causes the elevation of the oating-arm 46 from which the pin 47 extends, and the consequent artialrotation of the rockshaft 48 with w 'ch it communicates. Finally, as the wheel; continues its double circular movement, the pin 47 is rolled. out of its. notch, the floating-arm 46 simultaneously deflecting with reference to the swinging lever 45, and the sp 52 return the. parts" to t eir original positions.

place if so desired each time the engagement of a gear-wheel 18 with its driver 19 occurs, and hence a feeding movement result for 51 and the finger.

A movement of a floating-arm 46 may'take each movement ofac-an'ier-section into the operative plane. A. variationin the amount or degree of this feeding movement may be desired, for instance, where a number of tlypes or dies of varying width are used.

his may be secured by altering the radial depth of the notches upon the feed-Wheel or gear-wheel 18, resulting therefore in the turning of the rock-shaft 48 through different arcs. It will be understood, therefore, from the foregoing that the entrance of a pin 47 into a particular notch 53 corresponds to the ed or impression point. ntermittent rotary motion may be imparted to a feed-shaft 54, here shown as being arranged at the top of the casing 9, from the rock-shaft .48, by means of a system of gears 56 at the side of the casing, which may include a pawl-andratchet mechanism 57. V

The resent embodiment of the invention beings own as'a t ewriting-machine, the printing platen may 6 in the form'of a rotary cylinder 60, guided to move with its companion pressure-rolls 61, 61, or anyother desired number, endwise. along the guidebars 62 and 63 entering 64 and 65 extending from the casing.

For the purpose of permitting an endwise movement of the rotary platen 60 and the pressure-rolls 61, 61, they may lie between side frames 66 and 67, secured together by a stretcher-rod 68. The feed-shaft54 may be of any preferred construction to effect the endwise intermittent feeding movementof the rotary laten 60. As shown, it is formed with a ratchet thread 69, with which engages an arm 70 extending from the frame :67; This arm 70 will preferably bep voted to-tlia frame and pressed cipwnward mto'engagee appearance of a particular type or die at the stationary brackets ment with the ratchet thread 69 by a spring 71, for instance, which will permit a disengagement from the thread by the exertion of a pressure upon the outer end of the arm. The platen ,60 may have the usual return spring (not shown) while the inclined surface of the ratchet thread 69 allows the arm 70 to slide endwise on the feed-shaft when the platen is pushed backward along its guides. A ratchet mechanism may be provided for imparting a step-by-step rotation to the platen 60, and itmay comprise a pawl-open atin handle 7 2 carrying a spring-pressed paw 73 engaging with a ratchet-wheel 74 affixed to'the platen or an extension thereof,

While a more or less continuous rotary movementmay be given to the platen'manually by means of a thumb-wheel75, secured to the guide-bar 62, which for the purpose is mounted to turn in the end brackets 64 and 65, and is provided with a longitudinal groove -76 into WihlCll extends a pin (not shown) projecting from the platen 60'. A retaining device designated by 7,8 is shown for holding the/platen 60 in a desired rotary 'posltlon. Agpaper guide, designated by 79,

may also be used for retaining the paper in the proper position on the platen.

' ing thus very nearlyfa complete revolution The usual ink ribbon, designated by 80, may have the take-up roller 81 of the mechanism driven in any suit able manner-for instance, as herein shown, through a system .of gears 82 from the feed-shaft 54. Prefer- .ably, the take-up roller 81. has a frictional connection with its driving-shaft 83 to permit of a reverse movement of the roller around its moving driving-shaft when the ribbon 8,0 is wound back upon its supply roller by means of a crank 85. The supply roller 84- is prevented by suitable means (not shonn) from operating too freely. These requirements are usually fulfilled by the ordinary inking ribbon-device and the mechanism need not therefore be here more fully described.

It has been stated thatthe type or'dies upon each carrier-section is different from the types or dies upon any other. If this is the case it may happen upon'the trippingof a latch mechanism to permit its latch to protrude into the path of the corresponding starting-arm 28, that this-particular arm has just passed the point at which it would be actuated. and. set; -motion. therefore, ente'nuponits rotary motion until it has again reached the projected latch, makabout-the axisrof the. turret 6?, It may, howeverfbeadvisable to reduce this possible maximum periodelapsing :fromthe time of the manipulation of alatch mechanism until impression shall be made, and for this purpose any impressor mounted upon the series of carrier-sections formed by the sections attached to one or morecf the'series of shafts may have one ormore duplicates inthat It will not,

series. In the present instance the carrier sections upon the intermediate shafts 4 are provided with impressors which are all duplicates of each other, while the impressors upon the carrier-secctions of the exterior shafts 6 are arranged in pairs, those on the diametrically-opposite shafts being duplicates. All the impressors on the c'a'rriensections to the inmost shafts5 are,however, disward after a st arting-arm 28 has passed, then the arm of the sh aft whose section is provided with-the duplicate impressor will be actuated and thus the necessity is avoided for the starting arm which has just left the actuated latch mechanism to make a complete revolution before the desired impression can be made. i

The customary space-key is shown at which operates through an intervening rocklever 29, latch mechanism, and starting arm 28 similar to those that have been described to initiate the rotation of a shaft for the purposeof shifting the same toward the operative plane.

Each such section is-secured to its shaft by attaching the same to a radial .120 .tion of the shafts and subsequently reasflange upon the shaft, and these flanges are of such relative diameters'as net to interfere w th the removal of any section when the outer ones have been: takenoff. The flange 6 oft'he shaft 6 is preferablyprovided. with Y an-annular groove or channelfi forming a Y shoulder. overwhich the sect-ion 3 fits and against which it is forced arid held in place by the fastening screws 6', c entering threaded enings in the flange 6 and having their leads overlapping the section. Similarly the intermediate shaft 4 is provided with a radial flange 4 whose outside diameter is not greater than the diameter of the bore of the section 3. This flange 4 like wise has an annular groove 4 forming a shoulder against which the section 2 is clamped by fastening screws 4 4 entering threaded openings in the flange and overlapping the section. It will be noticed that the unbroken flange 4 is of such diameter as to cause it to extend over the fastening screws 6 ,6 and hence it may be recessed as shown at 4 4 to expose these screws. Similarly the inmost shaft 5 is provided with a radial flange 5 whose outside diameter is not greater than the diameter of the bore of the section 2. This flange 5 likewise has an annular groove 5 forming a shoulder against which the section 1 is clamped by fastening screws 5, 5 enterin threaded openings in the flange and oveflapping the impressor. Portions of this flange 5 may be also removed, as shown at 5", 5 to expose the fastening screws 4 4 Preferably the various fastening screws will be let into countersunk recesses to enable the sections of a set to be closely assembled. It is evident that the flanges of the different shafts perform a further function than constituting means for the attachment of the sections, as they,act as stops to limit the relative lengthwise movement of the shafts.

i mg'oft'he starting The operation of a machine constructed as illustrated may be described as followsAssuming that a key has been depressed, thereby actuating the rock-lever 29 to which it is 1 attached, the corresponding latch 33 is permitted to be thrown inward by the attached 5 ring 35, and the first starting-arm 28 in the I p ane of that latch to reach itwill engage with its end.- The continued'rotation of the turret 6 causes the engaged starting-arm to swing around, as also its shaft, (assuming that either the series of inmost or the series of exterior shafts is actuated,) untilby the contact of the cam-arm 21 with the inclined surface of cam 20 the gear-wheel 18, its shaft,

while the gear-wheel 18 simultaneousliv -meslies with the driver 19. The correspon ing detent'lfll has in the meantime sprung intothe groove 102, maintaining the parts in this axial'positiqn; Rotation of the said shaft now takesplace, the continuous swingthe meanat type or die $11118 reset the law-i133,

the pin 47 is free from the particular notch into Whichit enters to effect the feed the shaft 48, etc., are returned. to their normal positions by the spring 51 and elastic finger 52. Soon after this,by reason of the-continuedrotation and revolution, thecam-arm 23 contacts with the cam 22, and the shaft being free to move endwise is shifted back to its original position, the retaining detent 101 wheel 18 is withdrawn from the driver 19 si multaneo'usly with this return movement and the shaft brought to rest inits normal angular position by the elastic finger 27 assisted to some degree b the action of the detent 101, as aforesai Coincidently with the disengagement of the gear-wheel 18 the carrier-section has been shifted from-the 0perative plane leaving the intermediate carrier-section therein. If, however, a carriersection on an intermedlate shaft 4 1s the one that will respond to the depression of the key this shaft is not shifted axially, since the carrier-section attached thereto lies normally in the operative plane. The only-result of the engagement of the cams 20 and cam-arm 21 dueto the swinging of the starting arm 28 of the sleeve will be to shift the latter axially along the intermediate shaft and carry the gear-wheel 18 attached to the sleeve into engagement with the driver 19. A rotation is then imparted from this gear-wheel 18 to the shaft b means of'the pins 26, and an impres sion followed by a return movement ensues in the manner already described. A feeding ,movement'prior to the making of an impression occurs as pointed out before. 1 Having described my invention, I claim The combination, with a carrier adapted'to movein a closed circuit or orbital path, .of a set of shafts mounted one within. the
