Specification of Letters Patent.

Patented Dec. 7, 1920.

Application filed April 23, 1917. Serial No.'163,827.

1 0 all whom it may concern Be it known that l, VILLIAM V. KELLEY, a citizen of the United States, and resident Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in raper-Feed Troughs of which the following is a specification.

My invention relates to printing presses,

- and has particular reference to novel means associated with the feeding mechanism for guiding the paper to the point of engagement with the printing cylinders.

in printing presses, and particularly those provided with automatic feeding devices, the sheets are conveyed a certain distance from the feeding pile to the printing cylinders. It is difficult, if not impossible, to so arrange-the sheets in the feeding pile that each thereof will be delivered to the transfer or conveying mechanism at exactly the same point. It is, therefore, necessary that means should be provided for not only guiding the paper in its travel, but for shifting the same laterally, if necessary, to bring it into the proper relation with the registering mechanism at substantially the point of engagement by the cylinder. The registering mechanism will act to properly position the sheet if it is only a small amount out of register, but if received more than a half inch out of register it will not feed it properly.

An object in thepresent invention is to provide means in the form of channel shaped side guides which converge toward the printing cylinders and so arranged that any sheets fed thereinto will be guided laterally during the passage thereof from the feed pile to the cylinders. Means are provided also for adjusting the channels to accommodate different sizes of paper and for different angles of convergence. In addition means are provided for adjusting the forward ends of the side guides in such manner as to guide to either the right or left hand side of the press,-the registering mechanism acting to register but one side of the sheet.

An advantage in the provision of a closed guide such as disclosed is in that the paper is firmly held at its side edges without the liability of slipping out of the guide and being caught in any of the adjacent parts of the transfer mechanism. 1

The invention will be more readily understood by reference to the accompanying drawings, wherein,

Figure 1 is a side elevation partly diagrammatic in form showing a portion of an offset printing press to which my improvement has been applied; 7

Fig. 2 is a plan view of the same;

Fig. 8 is an enlarged detailed plan view of the form of connection between the two sections of the channel and,

Fig. 1 is a section on the line 47-4 of Fig. 3.

Referring more particularly to the drawings it will be seen that the printing press to which my improvement is applied includes feed rollers 10 to which the paper is delivered by pneumatic feeding mechanism not herein disclosed. It is conveyed from the feed rolls over a series of tapes 11, thence over a series of rollers 12, into position to be engaged by the printing cylinders 13. Transverse shafts 14, 15, 16 serve as. a support for the guide channels or troughs comprising my invention. These channels, as best shown in Fig. 4, may be formed from thin gage metal, the lower flange of the channel being somewhat longer than the upper, a deep groove being formed, however, for the accommodation of the edge of the paper. Preferably each side channel is in the form of two sections, 17 18, 19, 20. Brackets 21 on the upper surface of the channels provide the means for connecting the same to the transverse shafts. An adjusting nut carried by the brackets serves to secure the parts in adjusted position. By reference to Fig. 2 it will be seen that the channels 17, 19 preferably converge to the point of engagement with the channels 18, 20; the latter may be arranged in parallelism, if desired. It will be seen that if a sheet is laterally out of position when delivered to the channels 17 19, it will be gently shifted sidewise to a proper position. In order to adapt the guides to the sheet registering mechanism, I provide means such as shown in Figs. 3 and 1 for telescoping the channels in either of two ,positions. When the sheets are to be registered on the right-hand side, the channel 18 is moved laterally away from the channel 17 this being accomplished by providing a pin 21*, which may engage either of the two notches 22, 23, formed in an ear or clip 24:

on the channel 17. Preferably both pairs of channels are arranged in this manner and are alternately placed in a position as shown in Fig. 2.

By the provision of the simple expedient.

shown, the paper is accurately positioned and is not likely to escape from its guide in its passage to the cylinders. The exact form shown and described is not essential and it may be varied considerably without departure from the spirit of my invention.

I claim: 1. In sheet feeding means, the combination of means for conveying the sheet, and

a jointed channel shaped side guide for engaging the sheet throughout its travel and for retaining the edge of the sheet against vertical displacement, a portion of said guide being adapted for longitudinal inclination with respect to the travel of the sheet, sub stantially as described.

2. In sheet feeding-means, the combination of means for feeding the sheet, and channel-shaped side guides for engaging the sheet throughout its travel and for retaining the side edges of the sheet against vertical displacement, a portion of said. guide being adapted for longitudinal inclination with respect to the travel of the sheet.

3. In sheet feeding means, the combination of means for feeding the sheet, and jointed channel-shaped side guides for engaging the sheet throughout its travel for retaining the side edges of the sheet against vertical displacement, a portion of said guides converging toward the discharge ends thereof.

4. In sheet feeding means, the combination of means tor conveying the sheet, a

jointed, channel shaped side guide for engaging the sheet throughout its travel, and means permitting angular adjustment of the sections of said guide, substantially as described.

5. In sheet feeding means, the combination of means for conveying the sheet, a jointed channel shaped side guide at each.

side thereof for engaging the sheet throughg out its travel confining the edge of the sheet being conveyed, and means permitting adjustment of the channel sections relative to each other, substantially as described.

6. In a printing press, in combination, means for guiding the paper to a point of engagement with the printing cylinders, said means including channel shaped side guides arranged to converge toward the cylinders for guiding the sheets laterally to properly position the same for printing, the guides extending the full length of the space traveled by the sheet, said guides being adapted to engage and prevent disengagement of the sheet from said guides while the sheet is moving, and adapted for cooperation with guides of registering mechanism and arranged in a telescopic manner, and a means for supporting said guides to permit relative adjustment thereof.

means including U shaped troughs disposed for engagement by side edges of a sheet, the guides being formed of several sections arranged intelescopic engagement with each other, and means for adjusting said guide members laterally with respect toeach other to shift and guide the sheet into proper po sition for printing. 7

8. In a printing press, in combination, guide means for guiding the paper to the printing cylinders including a plurality of guide elements in end to end relation with the adjacent ends overlapping, the elements being supported above the conveyer tapes, each guide element being adap'ted'for movement independently of its connected element and in an angular position with re spect thereto, and means whereby the adj acent ends may be secured together to form a continuous guiding trough or separated to permit a non-guiding relation.
