Fig. {5 is n gl z-iiail pets )egtiveyiewpitheline spacing wheel with i n ti nloelg ing enge-ging niemhers, comeeteil new The cylindrical plat-en comprises the usunl sheath 1. and hollow core 2. The left-hand plnten head 3 is seplane'l ironi its adjusted position while an'engngement cured to the'phtten by headed wood screws 4 which platen head 14 which is shown in-detail in Fig. 4. The platen head 14 hnsa flange from which project pins 14 hus'n threaded neck 17 that extends beyond the 'for turning the ring to secure it'in place on the threaded the platen head and is held .agsin'st lbngitudinil'disiccts from thelinespa'ce wheel a locking lm'mher zfi having two ears 2'! that are apertdred 'to receivs-threaded screws 28, the stems oi which are threaded into heeded at 1.1 pussesthrough this opening and is repass through the platen head and take into the core oi the piston. An outwardiy-extending sleeve-like portion 5 is curried by the platen head and a spindle or stem 6 is received within the opening in said sleeve. A linger. wheel 7 is connected to the outer end of the spindle which projects thlough'a hearing opening in the plutcn i'raine 8, whereas the spindle and platen head are united by n (.(JllOltllll pin 9 which pnsses' thmugh openings in the sleeve-like portion 5 of the piston hood and through the spindle 6. A central opening extends through the platen hood and a bolt 10 ccivcd at its inner threaded end in a nut 12,.the peripheral threads on which cetipornte with the internal threads on a sleeve-like extension 13 of the right hand 16 that extend longitudinally of the piston and areadupted to be seated in suitable holes in the end oi the platen core 2 as indicated in Fig. 2, 'thuspreventing the platen head 14 from turning relatively to' the platen, whereas the bolt 10 secures the platen head 14 against withdrawal from the platen. A cylindrical portion 15 on the platen head 14 is adapted to be seated within the bore of the platen core 2 to forni a bearing for the platen head and the parts carried thereby as shown in Fig. 2. The platen head flange 16 and into screwed onto it an internally threaded ring 18 which is provided with spanner openings 19 extension-of the platen head. This ring is-stcpped on its periphery to form shearing portion 2;) for the inner edge 21 (Fig. 0) of a line spacing wheel or ring 22, and'a flange 230n the outer side of the line spacing-wheel or ring 22 fonpreventing movement-of theline spacing wheel towards the right and longitudinally of the platen. A peripheral bearing portion 24 is provided on the flange 15 of the platenliead and the'inner bearing surface '25 of the line spacingu'hcol rests on said part 24 and .thc flange l5 prevents s. movement of the line spacing wheel to the left andlongitudinalliy of the platen Thus, the line spacing wheel is mounted on placeinont'thoughr'it'is' free to turn thereon for a limited distance, nswill hereinafter more clearly sp'pean- It shown in Figs/2 and 4, n longitudinal-slot is formed in said piston head and said slot extends from a point near the-inner end oi the tubular port 13 and through the cylinder 15fand flange 15, but'itdoesnot extend. into the threaded neck-17; Into this slot thm'e protapped openings the line 'spncing ring orwh'e'el to rigidly connect-the locking device to said wheel. This locking device hos inwardly pmjecting fingers 29 and 29 on opposite sides of the longitudinal nxis of the platen and those fiugeisnro bent slightly. to 'form' in-. clinod or wod'ging surfaces assiiidicated in Fig. 2.

These fingers are bent in the some direction-that is to say; they are substantially pornllel. They both lie in dinaily oi the platen. 'lhisgnide or carrier is shownin detail in Fig. 9 and comprises a cylindrical portion 31 that is received in the tubnhtr extension and guides-- the carrier in its longitudinal movement therein. A flattened cut away portion 32 on the carrier constitutes a. flat bearing surioce against which the inner flat hearing face 33 of n pivoted wedgin'g device 34 begins. This pivoted wedgingdevice (shown in detail in lfigl 5) is pivotally connected to the carrier by a shouldered pivot screw 85, the thrca tdeii-stom oi 'ivhich is received in s. tapped opening .36 in the carrier, so that the pivotal exisof the pivotal wedging device extendstrsns- .versely totho axis of the platen. The pivoted locking device 34 'is preferably'madewi asingle piece of'shoet metnl struck upinto theiorinr indicstd in Fig. 5 with opposite flat iacesSH and 3'? and wedge-like or inclined portions 38 and 88 on opposite sides of its pivotal cen' ter. These inclined lanes 38 and 38 inc adnpted'to cooperate with theinjclined fingers 29 and 29" to effect e wedging and interlocking engagement betweeii the p ivotcd locking member 34 and the locking device 26 carried by the line spscing wheel to prevents relativeturning movementof one independently of the other.

As has been observed, the tubular extension 13 on --the piston head-l4 is slotted on opposite sides .t 39, end the locking member Stextends througi. those slots in the tubjulai extension and the flst'boau'ingsurface 37 bears against the .edges oi wells of the slots at oncside thereof, as shown in Fig. .2"; so that the locle ing member end its cariier 30 sreprevented from turning relatively to the platen heofd lfl th'otigh2said locking member may receivea pivotal movement on its cnrrier around the pivot sc'rew 35 and may likewise receive a bodily-movement with its earlier longitudiznnlly of the platen; The 'bodily' movement of the carrier in' one direction is effected by moons of a.

compression spring lO vh ich hears at one end against the nut 12 and is prevented frorn lateral displacement at that end by a projection 41 on thenut and at its opposite end the spring beers against the carrier 30 and is prevented from lateral displacement st that end by it stud' 42 which projects from the coirier and is received within the spring; The carrier is moved iri the opposite direction by a spindle 43 received within the hollow steni 44 for the finger wheel 45 'at the right hand end oi the platen. The stcni 44 is seated within a sleeve-like extension 46 of the thrcnded ncclg 7 that projects from the platen head 14 nndzsaid sten is secured in ,place therein by s. set shrew 47, which is threaded into'an opening in. the

entension 46 ,and bcnrs at its inner end ngainst the 'stem 44. A pin 48 extends through the hollow stem "44 andpt its inner end is received in a. cut out portion 49 in the spindle 43, in order to limit the movement of the spindlo and prevent'th'e withdrawal thereof from the hollow stern. A finger picce'or button 50 is provided at the outer end of the spindle to facilitate an actuation there-oi. As the looking fingers 29 and 29' are received within the slots 39 adjacent to the forces the carrier 30 to the right, thus carrying the wedge-shaped locking device 34 into interlocking engagement with the locking member 20, which is rigidly connected to the line-specing wheel, and the wedging notion will produce a close fit and the device TH will positively lock the line spacing wheel to lU- into to the platen. The locking device 34 iii tliue wedged in between the arms and 29* on the one Hide and the wall ol the slot 39 in the pluteh head 14, on the other side. The. line space wheel being held by the detcnt roller 52, the platen iii positit-ely locked ngnii'lst. rotation relatively to said line space wheel toword the back oi the machine by the engagement of the wedge 33* with the inclined nri'n 29 and it in positively locked against rotation in ,the other direction by the eugngcment oi the wedge 38 with the arm 29. The platen is thus positively locked against rotation relatively tothe line space wheel in either direction. In order to elloct n disengagement of the locking members, tonfiord fractional line spacing, it is merelynecessnry to In we the spindle 43 to warde the left thereby moving the carrier 30 against the tenison of its spring 40 when the wcdgin g d evicc. 34 had been'cerried ut of engngmnent with its cooperating engaging memer '25 "1rd the platen will be free to be rotated -indepondently oi the line spncing wheel a distance e'orre-.

When pressure is relcaned' on the finger piece the tension of the spring 40 will move the cn-rricr l0 longitudimilly of the plot en to the right and will ngitin move the wtdging device 34 into "i. different conditions deponding'upon the adjustinu-rlmzking and wedging engagement with the lingers 2 1m! 2!. During the engagement ol the locking members the pivoted locking device .i-iwill antomnb. icnlly adjust itseii around its pivot 35 to the adjust.- nn-nt effected between the line spacing wheelgirxl platen and between the two wedge-like locking mom-- hers. l lns'ing the reiingngunient of the ports in the mount-r nlltl-L'tl the wedge-lilieportion 38 or 38 be ght into ooijpcrntlon with the lingers 29 and 2 mcnt between the line :qm-eing wheel and platen. 1i, i'mninstnnee, the adjustment is such that the fingers 29 and 2!) are about centered irnthe slots 39 as shown in Pig. 2, tin-n the inclined faces 38 and 38' will approach their cooperating members 29 and 29 simultaneously and will lock the parts together without necessarily utter-ting a movement of the engaging member 34 nround its pivot 35.
