l Claims (Crier-65) Lvk This inventionr relatesv to printing machines and more particularly to printing machines through Which variable printing devices are sequentially passed from A which printing impresc-Y sions are made. Y

It is often desirable that an additional yprinting impression be `made adjacent the printing impression made from the variable printing device as, for example, when it is desiredto yimprint a date or the like, and the salient,v object of my invention is lto provide a novel .printing machine in Which such an additional printing' impression may be made.

Another object of the invention is to provide a frame that may be mounted adjacent the usual printing position inthe machine and in which frame the printing device for. the auxiliary printing impression may be arranged.

Further objects of the invention are to provide an ink ribbon for the auxiliary printing device and to provide a `Winding device for this ink rib- -bon that may be mounted on the frame providing the mounting for the auxiliary printing device.

In the selected embodiment of the invention illustrated in the accompanyingdr'awings Eig. 1 is a longitudinal fragmentary sectional view of a printing machine embodying my invention;

Fig. 2 is a .fragmentary plan vievvv of chine illustrated in Fig. 1; and

Fig. 31is a perspective detail View 'of the auxiliary printing device receiving member.

the ma- In the accompanying drawings ywherein aselected embodiment of my Anovelprinting arrangement is illustrated, 4 indicates the frame ofjth'e machine and on a bracket 5 on the frame a motor 6 is supported. An endless belt 7 is directed around thedriving pulley 8 of the motor and. V around the driving pulley 9 xed on thefdrive link 20 is pivotally connectedat 21. Anarm 22 is xed tothe rockerlfand the link 20 ishpvotally connectedtheretoat 23. The variableprinting devices `are `introduced into a magazine M arrangedin one end of the machine abovethe printing device ,guideway 24 in rwhich the reciprocating printingfdevice feed bar- 2,5 isslidably mounted 'on which pawls 26 are provided which' successively vengage therea'r edges'ol the-printingdevices D vduring reciprocationkof` thefbar 2 5 A to feed the printing devices `along the vguideway 24v in a step by step manner into printingposi- (imY non above the anx/i1 27.: Afrtheprmnpe Qd?- vices D haye beenpositioned above the anvil 27 they are directed 'over the guide 28'past thepacler 29 into the galley 30 Whereinthe' devices are' collected and stored inthe same sequence asthat if in ,whichI they were arranged,Whenintroduced d into the magazine M The platen arml is iixedv on the platenarni shaft 16 and adjustably mounted thereon is theusual platen P.
