lime 5% 3 3 c a Z the platen t aidewise to either the left or the right side,

edge of the platen. The ends 55 of the rollera and are provided with a right 12.; hi and a left hand thread between the Markets 54 and 29 and the ends of the rollers, and nuts 56 are adapted to be fastened by screws 57 to the brackets 54 and 29 a: to engage either the left or the right hand threaded portion of the ends of shafts 51. So illiilTglS the blanket is moved on no roiiers 36 and 30 will move thus side registering the edge of the sheet e printed ,en 42 which will bedescribed in the faliowing. As shown in Fig. 6 when the i i vzket is operated the rollers 36 and 30 be carried to the left and that side of est registered. The one nut 56 is oil an in dotted lines as only one at a time be In Fig. 3 these parts are rod is held in the brackets 29 by thumb screws 39 and on this rod is supd brackets 40 by thumb screws 41.

e brackets 40 carry the side registering guides 12 screwed fast on the brackets 40 and on these guides are carried the top guides 43 the forward ends 44 of which are bent upward. A thin strip of suitable r rial 45 is fastened under the guides 42 that ways 46 are formed on either side Lma'een the strip 45 at the bottom, guides on the side and too guides 43. This is point 47 and are v a and down motion to h end i ably made of ent malziizi. Sprii as 43 are also CRTlSCl I 4*" and have a tongue 40 ame width as the top guides 43. The side guides 42 are slotted as indicated at 5.0 and through the siots extend the ends of the bent rods 51 which carry stops The rods 5]. are adpratabiy carried by the brackets 40 as shown.

()1: the inking mechanism 4 is provided a he 53 to which the free end of the tape attached.

The parts above described are easily attaehed to the press by bolting on the two brackets 6 for the conveying I. eclianism, the brackets 29 and 54 to the platen and the book 53 to the inking mechanism.

in. making the press ready the thumb screws 41 are loosened and the brackets 40 are swung upward, the blanket is then detached from the roller 30, the surface of the platen made ready and the operator can prepare for the printing. WVhen the parts are replaced and the press started the operation is as follows: A pile of sheets is placed on the table 9 and the single sheet is fed by hand on to the fingers 10 and against the stops 12, which at that time rest upon said fingers and the cam r011 22 is on the against the fixed side register The top guides The kickers 1? sheet falls be- /Vhen the roll high part of the cam 23. will be so adjusted that the tween them and the stops. drops upon the low shaft 7 is rocked upwardly and the shaft- 8 rocked downwardly to the left as seen in Fig. 2-with the result that the stops 12 are lifted, the fingers 10 are lowered slightly, the guides 14 move downwardly to the left and the kickers 17 kick the sheet rearwardly on to the blanket 35, the sheet being side guided by the guides 11 and fed under the portions 44 of the top guides 43. At this time the hook 53 on the inking rollers move upward, the tape 32 is slackened and by the action of the spring 37 the blanket is pulled rearwardly carrying the sheet with it rearwardly and to the one side until the sheet reaches the stops 52, the edges of the sheet being guided in the ways 46, and the perfect side register being obtained by the shafts 55 engaging either the left or right hand threaded nut 56. The platen now moves down into printing position and when the impression is made the form member acts on the springs 48 which in turn depresses the top guides 43 to hold the sheetfirmly while the impression is on and strip the sheet from the form when the latter moves rearwardly. Thile this takes place the tape 32 is slack as shown in dotted lines in Fig. 1. On the return stroke of the platen and before the next sheet is kicked on to the blanket, the roller 30 is rotated by the tape 32 being pulled taut as shown in full lines in Fig. 1 and, thus the blanket is moved against the pull of the spring 37 and the printed sheet is carried out under the fingers l0 and delivered in the box The hook 53 now moves upward again and the next sheet is carried into position on the platen.

The above is thought to clearly describe and illustrate the construction and operation of my device and it has been that the same will operate quickly and satisfactorily. Changes may of course be made and I do not wish to be limited to the exact structure shown.

I claim 1. In a printing or other machine a movable platen, a platen locking cam and an inking mechanism in combination with a blanket for moving a sheet on and oil the platen, means for operating the said blanket from the said inking mechanism, a conveying mechanism for conveying a sheet unto the said blanket and means for operating the said platen locking cam." V

2. In a printing or other machine the combination of a movable platen, rollers mounted on and at'the front and rear edges of said platen, a blanket carried by said rollers and operated thereby to carry a sheet part of the cam the found conveying mechanism from the said into printing position and deliver the' printed sheet and means for moving one of said rollers longitudinally to register said sheet.

3. In a printing or other machine having a movable platen and a laten locking cam, the combination of a ceding mechanism, means for operating the latter from the said locking cam, a blanket means for supporting the same on the said platen and means for operating'the said blanket to receive a sheet from the said feeding mecha nism to carry the said sheet into printing position and means for operating said blanket to register the said sheet.
