At itsupper end is the'hent out pertion 4" which impinges the roller carriage d 3 in such a manner that the spring is thrnst forward and backward alternately by he Vertical motion of the rod 3. h 9e1 1d 10 represent thegripper finger bar suppprts tfteched one at each end of the 'lciwetedge ofthe platen 2,'and in which the gripper finger bar 11 is pivetelly mounted inlsileh a manner and with suitable attach V merits; not forming part of this invention, fofreisingandloweringthe gripper fingers -12, 12 as the platen is recited backward and d1; forward; this manner of Opel-sting the grip- @p enfingers being eommon to such presses andnotforming any pert of mypresent inventien. The spring 13, attached to the adjust-'1 lowermost portion o'fgthe bar 11, holds the fendofi grippenfingers, normally, in a withdrawn d flee position:

154p epresents 5t shaft extending parallel wwith andbetween the bar 11 and the platen BHa-ndw is jeur'naled; within the supports 9 5 end 10 and formsthe pivotal supports of the be r 11, this shaft being susceptible of j longitudinal reeiprocation independent of d the bar, and pl oinicting sufficiently at one ,end to engage the spring t by means of the reller 15, pivoted within thesocket 16 at ingde viceh f tacliedftothe end of the shaft 14. About 10, ijs menu-ted the spiral spring 18 cem- I pressed intermedietethe end bearing of the lbenll and the collar 17, whereby the 0pp0- Q siteflend of the said shaft 14 is maintained normally in an extended position. '19 represents the flat j metel arm at the registering device heving'at its free end the 'projeeting tapering fingerQO. At its opposite endthe arm 19- isetteched to a sliding 3 sleeve 21 upon the shaft 14: and is surinountediby lthe, fiat metallic spring 22,Ithe latter spring and the erml?) being attached to the flcsleeve 2l by means ofthe screws or rivets 30.1 In this devise the fiat'spiing 22 forms feneend penti @the shaft 14, adjacent the pivotal support 90 I ettgt he thewadjusting means by virtue of the pin 23 ch'neby meensqoftheWmeunted upon itslfree end endthe transe1thereentbyi nieens vei'segslotsnor,grooves24 Within the upper i sutfz'ceof the shaft 141 it By this meens any desired adjustmentlongitudinal the shaft 14 cmaybezmainteinedxregardless of the slight 11 0 Y 20 collar 31 is the slidable triglge the upper surface of the latterby means of j t 0 spring 28. At the opposite or actuating end of the rod 26 the end is bent at rightangles parallel with the finger 27 and again at right angles parallel with the principal part of the rod 26, forming the crank arm Q29 pro ecting over the edge of the platen above the shaft 14,

Adjacent the sle'ev'e21, mounted upon the shaft 14 between the said sleeve 21 and the r 32 provided with thepin 33 whereby t tains a constant position upon't e peripheral surface of the shaft 14 .by means of a groove 34 wherein isinserted the pin 33,

j thus allowing ofa sliding motion 1ongitudinal the shaft 14 as the registering arm 19 is moved backward or forward upon theshaft 14 for the purpose-of adjustment. A metal strap 35is "provided whereby the sleeve 21 i and the collar 31 are maintained in correct relative position regarding each other, in

order that the various parts of the registerin'g mechanism maybe adjusted as a unit.

At the end of the shaft 14, opposite that p impinging on the spring4, the same being projected beyond the pivotal gripper .finger ,bar support 10 wherein it is journaled and capable of. free motion longitudinally, is pivotally mounted a tripping member com '40 prising a suitable arm 36 so bent as to en gage with the gripper finger bar 11, and

- aving an equalizing weight 37 to insure the proper action of the tripping member,-as hereinafter shown. To assist the action of a this member I have also beveled a portion of the edge of the gripper finger bar, as illustrated at 3,in such'a manner that the arm.

36, when bearin'g'upon tha t. portion' of the bar, 11, will slip off and assume a positionbehindthe same. e

The shaft 14, being attached to the platen 2 and the gripper arm 11, descends-with the same, the roller 15 hearing against the spring 4 by means of the pressure of the p spring 18 and describing thearc A-B' uponthe same, as indicated in Figs. 2'a-nd 3. From-the manner of its attachment and construction. the arm 19, with its members 20, 21,26, etc, will move backward and for- .60 ward with the like motion of the shaft 14,

- as actuated by the spring 4, or as it follows the peculiar. shape of the same, since, in cross section, the spring 4 bends outwardly from A to B, admitting of the shaft, in its descent to project in that direction, drawing e tri 'ge'r main-' is tobe printed, indicated-as 39 in Figs. 1

' thespring 18, which is also assisted by the the registering apparatus with it. The spring 4, in cross-section, also having the; bent out portion 4' at its upper extremity, wherewith it engages the rod 3 on the. latvters upward stroke in such a manner as to thrust the spring 4 toward the platen, resulting in a like motion in the registering device through engagement with the end of the shaft 14.,

In thecourseofoperation of this type of printing presses the platen is at nearly a orizontal position when receiving a sheet and revolves through an arc of a circle to nearly a vertical position. when printing,

during'which arc the gripper finger bar 11, by means of cams, not,shown,assumes a position Lflush with. the platen. By sodoing the gripper fingers 12,12 'perform their function of holding. the sheet in place for printing; As is common, in" this manner of printin presses the rod 3 rises-as the lower edge 0 the platen-begins to descend. Thus,

with my device attached-thereto, the shaft 14 and the roller 15 will be at the position sh wnat A uponxth'e spring 4 w mm the lower edge of the "platen begins to descend,

Also the rod 3, in its upward motion, will impinge upon the -inclined portion 4 of the spring 4 and thus, through engagement withthe shaft14, produce a like'actionupon the registering members Thus it will be seen that when the platen-is receiving a sheet for printingfthe 'roller .15 mounted upon' 'the shaft 14- will be rising to the point A upon the spring-Cl and the bent out portion'4 offthe spring 4 will impinge the side of the rod Therefore the'shaft 14 will be approaching its most extreme distance fromthe-rod 3 and, as a consequence, the arm 19 and the co-respondent rod 26 will be approachingthe sheet to be printed with the fingers 20 and 27 distended. At the culmination of this motion, which is timed to occur at the exact moment the sheet and4, is placed upon the platen by' the feedingdevicc, not shown, the roller 15, and consequently the shaft 14'and its depending members, will have reached the extreme point of; reciprocal motion, at which point I the other-extremity ofthe. shaft will-have thrust the tripping member 36 from below the gripper bar '11, thus allowing the shaft" 14 torevolve sufficiently upon its axis, by reason of the twisting motion imparted by 120 weight 37, to allow the trigger 32 to fall uponthe surface of the platen, thus releasing the crank arm 29 and consequently the finger 27 impinges the sheet 39 between the 125 same and the finger 20. 'As has been said the rod 3, descends a'sthe lower edge of the platen rises. Therefore, at the position noted above, the .rod will descend;- to its lowest pointas the sheet to be printed is seized Att slpointthe f 2.
