SHEET-TURNING DEVICE.

Application filed Gcteber 23, 1922.

paper is ruled in two directions, but the invention is capable of use for other purposes than for ruling.

In the machme heremafter described, as

being an embodiment of my invention, the paper, as it comes from one ofv the ruling devices,'is delivered therefrom into the turning machine .upon a set of rollers, against which it is held by idlers, and is fed thereby to an arcuate slot, extending at an angle to the path of the paper, and is, by said-slot, turned at right angles to its former course. Thepaper is then reversed by means of tapes and rollers to bringthe initial upper side again to the upper position, and fed onward -11 on'ta es to a belt runnin at ri ht an les P a b b to its course, and being pressed against said belt'by idler rollers is fed outward thereby to the second ruling device. The last named idlers, which pass the paper against the belt,

have beveled ends, to ensure the paper enga-gingunder them, though its end may be somewhat ipcurved from the various operations already undergone.

In the accompanying three sheets of draw- 7 ing, 1 have illustrated the machine above referredto as anembodiment of my invention.

The figures of the drawing areas follows 2- Figure 1 is a top, or plan view of the machine.

Figure 2 is a side elevation, as seen from he side at the lower edge of Figure 1.

Figure 3 is a partial section, showing the reversing mechanism. The section is taken at the line 3, 8, Figure 1.

Figure i is a fragmentary sectional perspective view showing the arcuate turning slot and contiguous parts, and a slip of paper oing through the same.

the front of the machine, or the side at the 56 left of Figure 1, and shows the driving mechanism and the rollers and idlers at right angles to each other.

Figure 6 is a detail, the final delivery belt and an idl r coop- 60 erating therewith, and the means for tensioning the belt, and the means for support-. ing the'belt.

Figure 7 shows a means of adjusting the bearings of rollers.

Figure 8 is a. fragmentary plan view of a modified form of the shunting device.

. Referring to the several figures, and more esaccially, at first, to Figure 1, the paper showing the top of 'is'entered from the side at the left of F igure 1, in the direction of the arrow, and be tween the rolls 1 and the idlers 2. These as to receive paper at its upper opening and guide it around the core 5 and deliver it at its lower opening, as seen more particularly in Figure in whichsuch a piece of paper is shown are. i

This operation reverses the ,paper and brings the lower side uppermost, and it must again be reversed to bring the initial upper side uppermost once more. To'such end the paper is received from the arcuate slot 35 4t uponrollers 7, at right angles to the rolls 1, and between said rolls 7 and pressure idlers 8, and is fed by them to a system of tapes or strings 9, shown more particularly in Figure 3, which extend across the machine to the guise roll 10, and convey the paper to that point.

These tapes pass over suitable idlers 11. The paper isheld to the tapes 9, by idler tapes. 12 passing over'two of the rolls 1].,

The paper is thus rewith its edge upon a belt 14, running at right angles to the tapes 9, against which it is held by the idlers 15. The ends of the idlers 15, extend over the tapes 9, and are beveled, as at 16 to ensure the edge of the paper entering under them. The paper, which now lies loosely on the tapes 9, is gripped by the belt 14: and idlers 15, and fed by them at right angles to its former course, to-the roller 17 and idler roll 18 and by them out of the machine at the side at the right 01" Figure 1 and there into any device or receptacle adapted to receive it, such as a second ruling device.

At 19, Figures 1 and 5, is shown, a conventional type of drive pully, and at 20 and 21, various pulleys and belts for oper ating the moving members of the machine. One of these devices gives motion to roller 17 carrying the belt 14:. The latter is supported on rolls 22, one of which is shown in Figure 6 arranged preferably under the pressure rollers 15.. The tension of belt 14 is adjusted by mounting the end supporting roller 23 on stud 2 1, whichentends through .1 slot 25, in the contiguous frame member 26 of the machine, and threading the end of thestud and providing it with a clamp nut 27.

The tape rolls, or some of them, and

other parts, as idler roll 18, also require ad-- justment to regulate the tension of the tapes 9. To this end I provide the mechanism shown in Figure 1 and more particularly in Figure 7. 28 is a movable bearing block, which a roll may have a bearing, as at 29. This block 28 is traversed by a threaded shank 30 with a thumb head 31, by which the block may be moved laterally of the journal.

" In place of thebelt 14L, a series of rollers 32 coacting with the pressure roller 15 may be used for shunting the paper out of the machine. These rollers may be disposed between the horizontal tapes 9, as shown in Eigure 8.

Having thus described my invention, and an embodiment of it, in the full, clear and exact terms required by law, and knowing that it comprises novel, useful an-o. raiuable improvements in the art to which it pertains, I here state that I do "not wish to be limited to the precise construction and arrangement of the several parts, as here in set forth, as the same may be variously modified by a skilled mechanic without departing from the spirit and scope of my invention as defined in the appended claims.

What I claim and desire to secure by Letters Patent of the United States, is the following, to wit 1. In combination with the feed of a paper moving machine, a bar extending obliquely to the direction of feed, said bar having therein an arcuate slot through which-the paper is adapted to be fed, and by which it is turned at an angle to its initial direction. 2. A paper moving machine, comprising,

in' combination, a series of feed rollers and pressure rolls, adapted to feed paper, a bar, having an arcuate slot, positioned obliquely to the direction of said feed, and adapted to receive paper from said rollers a second series of rollers and coacting pressurerolls, adapted to receive paper from said arcuate slot.

3. A paper moving machine, comprising, in combination, a series of feed rolls and pressure rolls coacting therewith, adapted to feed paper, a bar havin an arcuate slot, positioned in the path or said. paper and obliquely thereto, and adapted to receive paper from said" rollers, a second series of tapes adapted to receive paper from said last named rollers and convey it onward,

rollers and coacting pressure rolls, adapted and means for taking said paper from-' sa'id 7' tapes and moving it at an angle theretoi 5. A paper moving machine, comprising,

in combination, a series of feed rollersand coacting pressure rolls, a bar having an arcuate slot oblique to said rollers, a second series of rollers and'coaoting pressure rolls oblique to said slot, a series of 'feed'tapes operating in the same direction as said last.

named rollers, and a belt and coacting pressure rolls adapted'to' feed at an angle to said tapes.

6. A paper moving machine, comprising, in combination, a series of feed rollers and coac-t-ing pressure rolls, a bar having an arcuate slot oblique to said rollers, a second series of rollers and coacting pressure rolls oblique to said slot and at an angle to said first named rollers, a series of feed tapes operating in the same direction as said last named rollers, and a belt and coacting supporting and pressure rolls, said pressure rolls having tapered ends toward the oncoming paper.

In testimony that I claim the foregoing I have hereto set my hand this 7th day of October, 1922. JAMES A. METS,
