SHEET FEEDING AND REGISTERING APPARATUS.

SPECIFICATION forming part of Letters Application filed May 20, 1881.

To all whom it may concern Be it known that I, LUTHER C." CROWELL, a citizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Sheet Feeding and Registering Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

In the operation of printing sheets of paper, and especially in printing the blank side of a previously-printed sheet, which latter sheets are necessarily fed a second time to the printing mechanisms, as well as in feeding printed sheets as supplements to mechanisms co-operating with printing mechanisms to deliver the sheets, so that a sheet just printed may have a previously-printed supplement properly com bined with it, the greatest feeding accuracy is required. This is accomplished in hand-fed times by register-points, and in some instances by pneumatic apparatus. In web-printing machines, however, where the long lengths of material are printed at very high speed, the sheets are produced by transverse-severing of the web after the same has been printed, and

the web is secured before the web is divided to form the sheets. In the present state of the art of rapid printing, more particularly that known as newspaper-printing, now generally performed by rotary printing-machines, in which a long length of paper wound up in the form of a roll is fed through the mechanisms, printed up on both surfaces, and cut transverse 1y through the margins to form the sheets, said sheets are either gathered into pairs, triplets, &c., to constitute awhole product, or the component sheets of the latter are simultaneously collected condition, or each successivesheet is folded and delivered. It has also become desirable and such printing-machines are now required to be provided with a means for associating with each sheet or set of collected or folded sheets one or more whole or part sheets, called supplements, which supplement sheet or sheets must, as is obvious, he so directed and governed in their travel through the mech- Patent No. 278,777, dated June 5, 1883.

sheet or sheets, or into the mechanisms controlling the latter, that the supplement-s'heet shall register with the main sheet, so that the combined sheets forming the product shall have their margins properly registered. In book or pamphlet work this 'is particularlyrequisite, since the succeeding pages brought into juxtaposition by folding the sheets into book form must register to produce perfect work. The controlling of the position of sheets following each other in rapid succession, either to printing mechanisms, to associating mechanisms, to folding mechanisms, or to delivering mechanisms, is a serious problem, and requires a most sensitive governing mechanism that will automatically and quickly regulate itself, for the reason that where the paper travels at a high rate of speed the slightest in accuracy of feed will quickly multiply, and

therefore soon destroy register, and result in much or too little ahead or b6hlIl(1.-O2LUS6S said 80.

controlling mechanism to come into action, and so operate the feeding mechanism as to cause the succeeding sheets to assume the correct position of register. Thus the sheets ar riving from any cause at the point occupied by this registering mechanism automatically act in passing the same to set into operation the means for correcting the faulty feeding movement, thereby not only preventing the extent to which a sheet may be out of register from multiplying, but acting to cure the cause by restoring the correct position of the mechanisms, or imparting to them an adjustment that will produce proper register.

The embodiment of this invention illustrated by the annexed drawings is a structure par ticularly designed for attachment to web-printing machines, and as thus embodied will be described, though its adaptation for use with hand and other sheet feeding means is con-- 10o templated.

In said drawings, Figure 1 illustrates by a side elevation, Fig. 2 by a plan view, Fig. 3 by an end elevation, and Fig. 4 by a longitudinal sectional elevation, a machine provided with my improved registering apparatus. Fig.

5 is an enlarged longitudinal sectional elevation of the sheet-feeding or position-controlling mechanism, of which Fig. 6 is a detail, and Fig. 7 a plan view, showing more particularly the gearing. Fig. 8 represents a front elevation, and Fig. 9 a longitudinal sectional elevation, (both drawn upon an enlarged scale,) of the mechanism for printing, perforating or punching, and winding up a supplement-web. Fig. 10 is an enlarged plan view of the registergoverning mechanism. Figs. 11, 12, and 13 are enlarged sectional elevations of said register-governing mechanism, showing the same in three different positions of its operations. Figs. 14, 15, and 16 are still more enlarged sectional elevations of said register-governing mechanism, showing three different adjustments of the sheet therewith. Fig. 17 is an enlarged plan view, and Figs. 18, 19, and 20 side elevations, of an electrical apparatus forming part of said registergoverning mechanism. Figs 21, 22, 23, 24, and are details of said electrical apparatus. Figs. 26, 27, and 28 illustrate a modi -fied construction of said register-governing mechanism; and Figs. 29, 30, and 31 show such modified apparatus, by much enlarged views of the same, in three positions of operation.

That the purpose and conjoint operation of this register governing mechanism with the delivery mechanism of aprintingmachine may be more readily appreciated, the structure and operation of the devices of said printing-machine and its delivery mechanism will first be explained, and then the co-operation therewith of the register governing mechanism will be explained. Referring, then, more particularly to Figs. 1 to 4, which are general views, the machine thus represented is one provided with means for operating upon two sets of sheets fed independently to it, and it comprises a means for printing one or both of said webs, as the case may be. It thus embodies here a rotating printing mechanism illustrated by the last type and impression cylinders A B, as well as cylinders G D, provided with cutting mechanisms coacting to divide, perforate, or punch said web. The cylinders A B are provided with toothed wheels 101 102, from which motion may be communicated to the various other rotating devices in proper time and direction through suitable gear-wheels. Thus the cut ting cylinders, which are provided with toothed wheels 104 105, are driven by an intermediate, 106, while the delivery mechanism,

which is shown to be a gathering apparatus consisting of a cylinder or carrier, E, and the necessary appurtenances, is set into timely mo- 'tion by a train of wheels, 107 108 109 110 111 51 being stretched from the pulleys 53, thence over pulleys 54, and returned around pulleys 5. The tapes 52 are stretched from pulleys 55 and return around pulleys 56. These tapes 51 52 constitute a conveyer carrying the sheets from the cutting-cylinders O D toward the car rier E, and run in contact as far as pulleys 56, the space from which toward the pulleys 54 is spanned by conductors 57 while the space between the pulleys 5 and the cylinder E is provided with a conveyer formed in part by the conductors 58 and tapes 59, which tapes 59 run from the pulleys 54, pass in contact with the lower surface of the cylinder E, and return over pulleys 60 61. A third set of tapes, 62, run from pulleys 63 in contact with the cylinder E and return over pulleys 64 and 65. Be tween the pulleys 60 and 63 a set of switches, 6, are provided, and these switches, together with the tapes 59 62 and conductors 58, form the means for guiding sheets upon said cylinder E and directing them around upon the surface thereof, such switches 6 also acting, when properly rocked, to enter their ends within the peripheral line of the cylinder E as a meansv for stripping a sheet or collected sheets from the surface of said cylinder, directing the same outward therefrom between the tapes 59 and other tapes, 66 67, the tapes 66 extending outward from the pulleys 68 and the tapes 67 from the pulleys 61, and together constituting a conveyer for delivering the sheets to a piling or other mechanism. These several tapes will be driven with uniform surface speed by motion derived from a toothed wheel, 151, with which the carrier E is provided, through toothed wheels 152, 153, 154, 155, and 156, with which the pulleys 64, 5, 54, 82, and 56 are provided, and wheels 157, 158, and 159, with which the pulleys 63, 68, and 60 are provided. (See Figs. 11 to 13.) No further description of this gathering mechanism need be made, since it is or may be substantially like that described in the Patents Nos. 192, 510, 192,954, 193,056, 213, 793, and is now a well -known mechanism for rapidly delivering sheets; and it will be understood, therefore, that a web ofpaper, as 99, may be led from a roll, as 100, through the printing mechanisms and the cutting-cylinders O D, and be severed or partially severed transversely by the latter to divide it into sheets or to define its line of such division, which sheets will be conveyed by the tapes 51 52 to the gathering cylinder E, and there be collected or associated to any desired number, and by the proper operation of the switches 6 the body of collected or associated sheets be directed in a pack to the tapes 66 67.'

The carrier E mayof course be provided with suitable mechanisms, and form part of a rotating folding mechanismsuch, for instance, as that shown in Patents Nos. 143, 674, October 14, 1873, and 171,196, December 14, 187 5or be capacitated to gather as well as fold, as in Patent No. 171,494, May 29, 187 7, or have the characteristics of construction shown in No. 192,034, June 12, 1877.
