A transverse keyway, kerf or "slot 14 is. formed in the platen head and in the nipple 10' for the, reception of a. feather or key 15 which has laterallyextending wings 16 each provided with-a cam on one side, as shown at 17. This key orfeather is 'driven'into an opening or slot in the spindle 11 and is set-- cured therein by a driveefit," Whereas those: :portions of the feather which projectflofit 'wardly'beyond the spindle are received-"in; a

The plug 20 as a. central bearin opening and the spindle 11 rojects throng said opening and has a earing therein. The inner end of the spindle carries a transverse pin 22 which extends from the spindle on opposite sides thereof and constitutes a bearing for a member 23 hereinafter called an actuatin device. This actuating device is clearly s own in Figs. 5 and 6 and comprises a sheet metal frame 24 that has bearing lugs 25 struck up therefrom. These bearing 'lugs extend on opposite sides of the spindle 11 and are perforated for the reception of the pin 22 which constitutes a guide for the frame and causes the actuating device to move with the s indle in its movement longitudinall of the platen, but afl'ords a movement 0 the actuating device at right angles to the axis of the s indle on the guide pin 22, for purposes w 'ch will hereinafter appear.

The sheet metal frame 24 has anopening 26 thereinglar enough for the free passage ofthe spind e through the frame and 15 formed with bearings 27 that extend on upppsite sides-of the indle and constitute arings for the ivots 28 of anti-friction rollers 29, said'ro' lers being located on op-' posite sides of the spindle. Inwardl roecting ton es or fingers 30 are punc e or cut from tfi: sheet metal frame and extend toward and into contact with the spindle on opposite sides thereof, as shown in Figs. 5 an 6. These fingers prevent any lateral movement. of the actuating device on the spindle in one direction but afiord a movement of the actuating device at right angles to the indle in another direction, or longitud' j y of the guide pin' 22. The antifriction rollers 29 of the actuating device coiiperate with inclined or cam' faces 81 on.

the long le'ver arms 32 of-the engaging or gripping devices. These rip ing devices may have outwardly extending. ifurcated or substantially U-shaped portions 33. An inwardly extending circumferential flange 34 on a line spacing wheel 35 is embractd withj in the bifurcations and lies between the gripping or clamping jaws 33 formecfb'y said tion as a whole thus far descri bifurcations. The gripping devices are received and seated within openings or channels 36 in the platen head, so that the are connected to turn with the platen hea and each griptping device has a portion 37 that is ada te to bear against the bottom wall 38 of t 0 associated opening 36 in the laten head. The line spacing wheel-35 is a apted to turn or rotate on the latch head and is secured from outward isplacement ,b a cover plate '39 (Fig. 1) which is secure to an outwardly extending boss or portion 40 of theplaten head byscrews tl received in threaded openin 42 in the portion 40, thus pigiily uniting t e cover plate to the platen vlea The tension of the s ring 19 is exerted to hold the spindle to the eft in Fig. 1, thereby moving the actuating device in thesame d1- 'rectlon, pressing apart the inner ends of the the platen'and line spacing wheel to I'Ojtgdj together. If theoperator should desireftof efl'ect'a fractional llnes acing movement of the platen, or to move t e necessary to press the finger wheel12 to the right, thus moving the spindle in a like di- .90 laten independ- 'ently of the line spacing w eel, it is merely rection a ainst the tension of the spring 19, thereby orcing the actuating device to the right to relieve pressure on the inner ends of the lever arms 32. When-the pressureof the spring 19 is thus relieved upon the lever arms 32, the finger wheel 12 may be utilized to rotate the platen to the desired extent, the

line spacin wheel at this time remainfixed, i cing held in place by the. .usu spring detent 43.-

. The advantages attained b theconstruc are similar to those more fully pointed out in my prior patents hereinbefore referredsto.

semblage of the parts.

W; l .be'mounted to turn in its platen frame in the usual manner and that any'ordinary line spacing mechanism may be employed to cooperate'with the line spacing wheel 'in the usual manner. p n

The constructions shown in F 9 to 13 be understood that the platen are in manyjrespects similar to t at shown in 'the figures and co ending reference numerals will be employs to ties;-

Iidgnate the 'partswhich are the sameiin the ifierent constructions. V

In the construction shown in Fi 9tlie inner end of thetubular extensio 21' is lili exteriorly threaded instead of being lateriorly threaded as in the other construction and the detachable perforated end piece 20 in the construction shown in Fig. 9 is in the nature of a co or miver plate that is interiorly tlueudec to cooperate with the exterior threads on the inner end of the tubular extension.

It will be understood from an inspection of Figs. 1 and 9 that two cut-outs or recensus 44 may be formed in the spindle 11 for cooperation with the set screw 13, so that the finger wheel may be connected to the spindle as shown in 'Fig. 1 or may be moved along and secured further out on the spindle. as shown in Fi 5). In the first mentioned adjustment 0 the finger wheel the boss 12' thereon will he nearer to the platen frame 9 in the normal position of the mrts and the tin -r wheel will be arrested rv contact with t to platen frame when it is moved to the right sooner than itwould be if the finger wheel were adjusted as shown uently a shorter lon iin Fig. l). and contndinal movement wi l be transmitted to t e spindle in one case than in the other for nil-poses which will hereinafter appear.

It is desirable to provide means for lockiug the releasing device in the released posi' tion in order that both hands of the o r- Ill-01 may be free to manipulate the mac ine when desired. To this end I have provided, in the construction shown in Figs. 9 to 13, means whereby the spindle 11' or 11" may be locked in the innermost or releasin ceition. Thus, from an examination 0 i 9. 10 and 11, it will be seen that two of 16 side walls of the slot or key wa 14" in the nipple 10 which pit-ejects inw ly from the le t-ha-nd platen cad, are cut away laterally at 45. Radial lockin depressions or notches 46 are formed in t e nipple at the tenninations of the cut away portions 45, said notches being 0 )positely disposed as indicated in Fig. 10, thus forming inwardly extending projecting lugs 47. between the side walls of the key-way slot 14 and the locking notches 46, which lugs are substantially triangular in cross-section as shown in Fi 10.

n the operation of the device shown in Figs. 9, 10 and 11 the spindle will be moved inwardly by the finger wheel 12 until the hosts 12' thereon contacts with the platen frame 0, therchy rcleasin the clutching devius in the manner heremlicfore described and when the linger wheel and spindle have remivcd the limit of inward movement the linger wheel may then he iron 11 mrtial turn, thus turning the feat icr l5" thereon into the laterally cut away portions 4-! to a xnition where it. may he received in the orlting notches 46. A release of inward pressure on the linger wheel 12 at this time will cause the feather in to be seated in the locking notches 46 through the pres-sure of the spring 19 as shown in Fig. indicated In dotted lines in Fig. ll. When the feather is thus seated in the locking notches the spindle 11 is locked in its pushed in position and the spindle and timer wheel are locked to the platen head and plhtemand the clutching or connecting devices are maintained released from eugagcnu-nt with the line spacing wheel. The linger wheel 12 may. at this time. be employed to turn the platen ilulepcndcutly of the lllll sparing wheel.

The construction shown in Fig. 12 is similar to that embodied in Figs, ll, It) and 11. except that the locking worse-s 48 are mntnined in the outer end of the nipple 10 instead of bein arranged in the manner shown in the other figures; and in the construction shown in Fig. 12 the parts are so arranged that a full, inward movcun-ut of the spindle ll will move the feather 15 entirclv out of the he -\\'uy slot H" and heyoud the inner end 0 the nipple. A slight turning movement of the s mdlc. when in this position, will cause the Feather 15" to be brought opposite the locking openings 48 and when the feather is in register with said openings the spring 19 will force the feather into locking eng ment in the openin s, as shown in dotted ines in Fig. 12, thus loc ing the spindle and fin 'er wheel to the platen head while the clutch actuating device is maintained in the released position and the platen is free to turn independently of the inc spacing wheel.

I have fprovided a still further form of the locking eatnre of the invention, which is illustrated in Fig. 13 and which, in practire, I refer to em loy. \Vhen employing this locliing device t e coil )erating parts are preferably mnstructed in ihe manner shown in Fig. 1 of the drawings, for instance, and the tin r wheel 12" is provided with a hoe-is or col or L! which has a circumferential groove 49 therein. The platen frame or carriago 9 supports a locking latch 50 which is in the nature of u U-shaped piece, the upright members 531 of which constitute linger l pieces for sliding the lurking member along the Hllll' bar of the platen frame on which it is mounted. The base of the limiting piece is slottel'l at 5:2 for the reception of stems of headed screws 53. The t ircadcd stems of slot In! and take the screws was through the i into thrcmlrd openings in the platen trunnand limit the movement of said locking member. l'ro'octing onnrurdlv and downwurdly from in luuic of the lurking nn-mhrr i In n hruclwl-hke urm M which terminates in u curved linger 55 which is adapted to lascat-ell within the circnmh-rcnlinl groolae 4h l in the hose 1:!" on the linger whorl when the 10 and as finger wheel has been moved inwardly to the limit of its movement and the boss has been brought into contact with the platen frame. When the locking member 50 has moved to seat the locking finger {i5 with n the circumferential groove, the spindle Will be locked in its innermost tion, thus maintaining the actuating device out of con tact with or freeing the pressure thereof on the long lever arms 3% of the tgtlr: connecting grip in evices so a platen is adapted toie turned independently of the line 5 acing wheel. The feather 1 however, in t is construction is seated at all times within the key-way 14 so as to prevent the spindle from turning relatively to the platen head and the finger wheel 12" may be employed to turn the platen, the lock ng device 50 not interfering with the turmng movement of the fininwheel, altho it prevents the tin or w eel and spindle to moving outwa ly in the direction of the length of the spindle until the locking memher 50 is again moved back to the normal or releasing position shown in F1 13.

It will be understood that the inner side wall of the groove 49 constitutes a circum ferential shoulder against which the lock bears to revent an outward movement of the spindle and that in the construction shown in Fig. 18 it is only this circumferen' tial shoulder which is essential for cooperation with the locking member.

The recesses or notches 44 hereinbefore referred to enable the finger wheel to be adjusted in either one of two positions as heretofore pointed out. When the finger wheel has been adjusted as indicated in 1' lg. l, for instance, it will limit the inward movement of the s indle and in a construction such as that s iown, for instance, in Fig. 9, will prevent the locking means from being rendered effective or o erative. That is to say, if the finger whee be moved inwardly on the spindle and the set screw 13 is seated in the innermost recess 44, then the spindle will be prevented from moving inwardly far enough to bring the feather 15 (Fig. 9) to a position where it may be turned laterally and enga in the locking recesses or openings 46. ll, however, the finger wheel be secured in its outermost position then the locking means are rendered operative when the spindle is pushed in.

The adjustment. of the linger wheel on the spllltllc in the manner described may' also be employed in a construction such as that shown in Fig. 12. in one position of ndjnslmen! of the linger wheel the feather 15" may he mow-d out of the key-way beyond the and of the nipple 10 and turned until it is Iii-ought into register with the locking openin v 48 and is seated therein. in the other It! juatment of tho linger wheel the spindle season will be prevented from moving for enough to carry the feather 15" out of the keywuIy 14".

t should be understood that various of the features separately shown may be combined and emp oyed in a single construction.

The means for lockin the spindle or actuating device in the re eased position constitutes an important feature 0 the present invention.

Instead of a feather, such as the feather 15'' working in a key-way in the manner shown and described, the ni pie 8 ma extend throu h the bearing in t e platen rame and beyon the side bar in which the bearing for the nip la is formed. This nipple may be rovided with a key-way for cooperation wit i a feather on the spindle and a cooperating locking notch or o enin such as 48 may be provided in the en of t e nipple 8 for cooperation with the feather. This will enable the operator to see whether the feather is seated in the locking opening or is in the key-way, or in other words to see whether or not the spindle is locked in the releasing position.
