` T u all whom ttmoy concern:

Be it known that 1, Gruner: F. Ruin, a citizen of the l'nited States, residing:r at London, county of Middlesex, England, have invented certain new and useful lmpiovenients in lrintiug-Ztlaehines, fully dc following specification and the accompanying drawings. forming a part of the suine.

his invention relates; to certain improvements' iu printing machines.

Certain classe of printing machines. such, for instance. :is newspaper printing,r inacliines which print on webs, as ordinarily arranged, deliver roducts consisting of four pages or multiples of four. In some cases. however, itis desirable to produce products which do not consist of multiples of four pages. such, for instance, as six or ten page products', these products being ordinarily referred to as products having inset sheets.

It is one of the objects of this invention roduee an. improved rinting machine to furnish inset products when desired. and to do this by mechanism which is simple, etl'ective and cheap in construction.

A further object, of the invention is to produce an improved delivery mechanism which shall be cn iacitated to produce inset products when desired and also produce roduets having four pages or multiples of our pages.

With these and other objects not speciliin view. the inrention consists in certain constructions and in certain parts, improvements and combinations as will be hereinafter fully described and then specifically pointed out.

In the accompanying drawings-Figure 1 is a diaframmatie side elevation of a printing machine illustrating the invention. Fig. 2 is n plan view of the construction shown in F ig. 1. Fig. 3 is un end view of the construction shown in Fig. 1 the osition of the observer bein;r indicated h v t ie arrow 3 Fig. 4 is u diagrammatic vieu' of a section of u perfected web produced b v the machine. Fig. is a peispeetive view two iositions.

l Machines construct in accordance with the. invention will usally contain a single printin couple the character of vclii'eh niav vary. n the particular construction which .plates arranged side by side of plates, as, for instance. the

has been selected to illustrate the invention, vthe printing lcouple comprises a printing cylinder 1 with which coperate two in:- pression cylinders 2 and 3. The printing couple illustrated is capacitatcd to siniul taneously print two webs 4, 5, the web 5, as shown, being a double wide web, and the web 4 a single wide web. As shown, the cylinder 1 is provided with one set of plates capacitated to produce six printed pages, the plaies being arrange-.d so that the eo1- umns run around the cylinder, and the plates and cylinder bein of such size that the surface of the eylin er is fully covered b v the lates. The plates on the cylinder may be inked in any suitable manner. as, for instance, by inking mechanisms diagrammaticallv illustrated and marked 6 and 7. Accor ing to the preferred form of the invention, and as illustrated, the webs after being printed are turned over and again presented to the couple side by side. so as to be perfected. The reversing of the webs may be effected by any suitble mechanism, such, for instance, as the usual turner bars. In

the construction illustrated, the bars for the i will be understood that the lates are so ixnposed upon the cylinder an the webs are so presented thereto that: the im ression proueed by one set of plates, re erring to the.

len hwise of the cylinder,- as a set, is backed y the inipression produced by the other set of plates.

his arrangement will be understood by reference to Fig. 4 in -which the impression produced by the first set the web is marked 2, 5, 3,`in full lines, and the impression produced by the other setof plates on the same side of the web is marked of plates on one side of 6, 1. 4 in full lines, whereas the im ression produced on the other side of the we by the lates is indicated by the dotted line num- It will be observed that the impression from what may be termed the first set ing pagesY 2. -5, 3. is backed by the iiiipression from the other set of plates, viz., the plates printing pages 1, 6, 4.A

In the particular construction' illustrated, the webs are led side by side from the web rolls over guides marked 14 and 15 between the 'printing cylinder and the impression cylinder 2, after rhich the webs are led by plates print- Y t have upon them'au associated A 55 sisting of a sheet from the wi e web, and a.

45' ranged to deliver to suita l 3 also revela-er the wel. in the particular cnncylinders. therefore. alternately Mh-|- struction illustrated. are led ver :i fnidr l*- lietwetn ilu printing.r cylinder and ire impre--ion cylinder 3. After hein;- printed. thc 'cbare led to a mechanism hy which the web.-- are comcrted into sheets. the sheets being associated into a properly paged product. While the mechanism referred to may be varied. in the particular machine illustrated. this mechanism includes two pairs of cutting cylinders, the cylinders of one pair being marked 19, 20, and the cylinders of the other pair 2l, 22. Each of these cylinders, in addition tothe usual cutting device. is provided with a set of pins, the. pins on the cylinder 19 being marked 23, those on the cylinder 20 being marked 24. and those on the cylinders 21 and 2:? being marked 25 and 26 respectively. Y .In the particular machine illustrated, the webs. after being perfected bythe cylinders 1 and 3. are led over a guide 27 after which .the web 4 is, by means of aides 28, 29 and 30, led to the pair of cylin ers 19, 20. The web 5, after leaving the guide 27, is, bv means of guides 31, 32, 33 and tween the cylinders 21, 22. Y

It will be observed that the pins 23, 24 on the cylinders 19 and 20 are so arranged as to ta 'e alternate sheets from the web 4 and that the pins 25, 26 on the c linders 21, 2:2 c, are also arranged to take ternate sheets 35 from the web 5. The pins will be further arranged so that the pins on the cylinders of one pair will deliver to the pins on the corresponding cylinders of the other air. In the particular construction illustrated, 40 the pins 26 on the cylinder 22 will deliver to the pins 24 on the cylinder 20, and the pins I 25 on the cylinder 21 willdeliver to the pins 23von the cyli.nder 19. The pairs 01E-cutting cilinders .will be arle delivery mechamsm. In the construction shown, two de- Y hvery mechanisms are em laye-fl, one of these' mechanisms taking s eets from the cylinder 19 and the other from the cylinder 5 20. These mechanisms comprise ordinary blade folders 35, 36, these folders delivering Vin any usual way. such, for instance, as by tapes 3T, to anI S-tly 3S which lays the folded sheets on a traveling belt 39. With this con- 545; struction it vwill be understood that alternate Y I 'l sheets cut from the wide web-will be taken the pins 25, 26. and' alternate sheets will,

-lnthe @me wav, be taken from the'nari-owA .1. web 4 bv the pins 23. `2t. The pins 23 will ic .uplt-ae wide web sheets from the a clln er 21. and the pins 24 will pickup the wide we .b sheets from the cylinder .22', so that the cylinders 19 and 20 will alternately roduct coned b- .siy paolplolllhl'l the folding two view.- of lln.` prmlact being .shown in Fig. lt will ln' l'urtlu-rseen that thcslu'ets are so arranged in this product that. the

pages fall in their proper order.

The particular machine illustrated has the ecial advantages that the product is proliiced by means of a single printing cylinder and a single set of plates. The construction furthermore, does not require any part of the machine to ran at half speed, as is thc case with certain machines which have been heretofore employedl for producing products having inset sheets.

, It is of course apparent that mechanism constructed in accordance with the invention 5 may be employed for producing other than a six page product by means of obvious modifications. For instance. by increasing the length of the cylinders of the couple, the same mechanism might. be employed for producimv a ten page product, or an eight. page product.

ther changes which will suggest themselves to these skilled in the artv may be made without departing from the invention. The invention is not, therefore, to be limited to the specific construction hereinbefore described and illustrated in the accom anying drawings.
