Means; (not shown)- are provided .{-for drivin one or more of the shafts around which the conveyors 23 and 24 are passed. The shaft 25 carries a pulley 45 and the inner shaft for the conveyor 23 also carries a pulley 46 and' 'afn--ex-" tensible belt 47 is trained around these two pul leys so that the perforator 21 is rotated at the same peripheral speed as the impression cylinder 18. By having the perforator"21"rotating at the same peripheral speed as the impressioncylinder,

any possibility of tearing an envelope upon the return of the :pe'rforaltorto operative position is avoided, 2:331 I In the operation of the ma'chine, certain. of the magazines contain envelopes which are not to'be perforated and pins' '44-areattached to the chain at proper places to render the perforator inoperativewith respect to'such envelopes Normally, envelopes are withdrawn fromth'e magazines and passed between the prforator'and the impression cylindento form a row'of perforations. -The perforator is held in operative relation to the impression cylinder by'reason of the surfaces: 32 being in engagementwith:thefshoiilders-29, due-to the fact thatthe plates '30 are'held" elevated by the arms 35 under theinfluenceof the spring 3'7, (see Fig. 1'): However,?upon engagement'of'thepin 44 with the arm'43; thepostg42 is-rotated and the link 40 pulled 'to rotate' the shaft 36, in a direction to move the arm 35 downwardly, thereby permitting the, spring 34 to drawlthe plates 30 from the position shown in Fig'. 2 to the position shown in Fig. 3. The perforatoris-therebymoved away from: the impressionucylinder and the envelope passing through the printing press at this time is not perforated As soon asiherpm 44 passes out of contact'with the arm-43, the spring'37 rotates theishaft36 to its orig'inalposition and the arm .35 movesthe plate 30-back into'the position shown inFig; 2, Jthus'=.bringing the perforator back intor'operative relation to the impression cylinder. l As many pins .44 maybe used as there are magazines 1 containingtenvelopes not to be perforated and these :pins are arranged on the chain at the proper points to trip. the perforatorat such time as one. of I these envelopes is passing through the press. In this way-,the special envelopes are handled similarcto the otherienvelopes and are properly arranged in reach-group of envelopes as the group 115 discharged from the 'printing press. Manual. insertion of special envelopes in the sets of envelopes is thus avoided. l

"Other partsof the printing press-may be actuated" or rendered inoperative by mechanism actuated by pins 'carriedby the chaintll. There may, therefore; be provided a plurality of collars'46 rotatably supported upon abase 46a and having arms projecting'into-the path of pins 44a carried by the chain' 1=1, (Fi'g'."4)-. The collars are'also provided with additional arms 48 suitably connected with the parts of the press to be'controlled. Usually, the-parts above referred to are not intended to be operated at the same time and therefore the arms 47 are operable-"at different times. For-this reason, the pins 441; "are provided with notches in alinement with the arms 4'1 not to be actuated by the particular pins. In this way, selective operation of the various parts is provided for.

It is of course understood that various modifications may be made in the apparatus above described, without in any way departing from the spirit of the invention as defined in the appended claims. 1

We claim:

1. In a printing press, an impression cylinder, a perforator cooperating therewith, means to feed envelopes or the like between the cylinder and perforator, and means controlled by said feeding means for temporarily moving said perfo- {rator out of operative relation to the cylinder.

2. In a printing press, an impression cylinder,

aperforatorcooperating therewith, means for feeding envelopes or the like between said perforator and cylinder, means for maintaining said perforator in operative relationlto said'cylinder, resilient means tending to move said perforator out of operative relation tothe cylinder, and means actuated by said feeding mechanism for temporarily rendering said maintaining means inoperative. r. f

' 3. In a printing press, an impression cylinder, a. perforator cooperating therewith, a movable endlessrow of magazines, means for withdrawing envelopes or the likefrom successivemagazines and feeding the same between said cylinder and perforator, and means controlled by, said row of magazines for temporarily movingsaid'perforator out of operative relation to the impression cylinder. i -l 7 v4. In a printing press, an impression cylinder, a perforator cooperating therewith, a movable endless row of magazines, means for. withdrawing envelopes or the like from successive magazines and feeding the same between said cylinder and perforator, resilient means tending to move said perforator away'from'said cylinder, means for holding vsaid perforatorin operative relation to said cylinder, and means actuated by said row of magazines fortemporarilyrendering said holding means inoperative. l

5. In a printing press, an impression cylinder, a perforator cooperating therewith, a movable endless. row of magazines, means for withdrawing envelopes or the like from successive magazines and feeding the same between said cylinder and perforator, means supporting said perforator for movement toward and away from said cylinder, resilient means tending to move said perforator away from said cylinder, means for holding said perforator'in operative relation to said cylinder, and meansactuated by said row 'of magazines for temporarily rendering said holding means inoperative. t r

6. In a printing press, an impression cylinder, a perforator cooperating therewith, a movable endless row of magazines, means for withdrawing envelopes or the like from successive magazines and feeding the same between said cylinder and perforator, and automatic trip actuated means timed with movement of said magazines for temporarily movingsaid perforator outof operative relation to the impression cylinder,

7. In a printing press, an impression cylinder,

a perforator cooperating therewith, a movable said perforator away from 'said cylinder, means for holding said perforator in operative relation to said cylinder, and means timed with movement of the magazines for momentarily rendering said holding means inoperative.

8. In a printing press, an impression cylinder, a perforator normally in co-operative relation therewith, a movable endless row of magazines, means for Withdrawing envelopes or the like from successive magazines and feeding the same between said cylinder and perforator, and means timed with the movement of said magazines for moving said perforator out of and back to normal position.

9. In a printing press, an impression cylinder a perforator supported in operative relation thereto and movable out of operative relation, a movable endless row of magazines, means for withdrawing envelopes orthe like from successive magazines and feeding the same between said cylinder and perforator, and means timed with the movement of said magazines for temporarily moving said perforator out of operative relation to said cylinder.
