MEANS FOR CHANGING THE DIRECTION OI MOVEMENT 0F SHEETS.

Application filed June 18', 1924. Serial No. 719,893.

The present invention relates to means for receiving successive sheets from one instrumentality, as for example, a rulingmachine, and changing their direction of movement to deliver them to another instrumentality, as for example another ruling machine.

The preferred embodiment of the invention is illustrated in the accompanying drawin s, wherein:

igure 1 is a plan view of the apparatus applied to two angularly disposed machinesi Figure 2 is a plan view .on an enlarge scale of the direction changing mechanism,-

Figure 3 is a side elevation of the same, as taken on the line 33 of Figure 1,

Figure 4 is a detail sectional view illustrating the suction controlling means,

Figure 5 is a cross sectional view taken on the line 55 of Figure'4,

Figure 6 is alon itudinal sectional view through the suction ead,

Figure 7 is a cross sectional view on the line 7--7 of Figure 6.

In the structure shown in Figure 1, a ruling machine is illustrated diagrammatically at 8, and another or second ruling machine is likewise shown at 9, these machines being disposed at right angles to each other, the

. v feeding end of the machine 8 being illustra'ted at 10, the opposite end being the delivery end. The receiving end of the machine 9 is designated 11, and a toboggan 12, including endless tapes 13, delivers sheets up said toboggan to the receiving end 11. In the corner formed between the delivery end of the machine 8 and the toboggan 12, is the direction changing means, (constituting the subject-matter of the present invention.

As shown particularly in Figures 1, 2 and 3, the delivery cords from the machine 8 are illustrated at14 and pass around a roller 15 A frame 16 has mounted therein a plurality of supporting rods 17 extending in rear and longitudinally of the cords 14.- These rods are preferably angular in cross section. Lo-

cated between the-said rods are carrier tapes 18 pasingaroundpulleys 19 at the rear end of the frame, said pulleys being carried by a shaft 20 driven by a suitable sprocket chain, a portion of which is shown at 21.

Arranged above the horizontal plane of the bars 17 and tapes 18 are endless cords 22 arranged in pairs, the rear portions passing around a roller 23, the front portions being mounted on' pulleys 24 carried by swinging arms 25 that permit the cords 22 to rest on the roller 15. mounted on a pivot rod 26 so that the pairs of cords may be spaced different distances apart. Thus adjustment is permitted and the arms 25 are held by suitable collars 27 slidable on the rod 26 and located between the bifurcated ends of the arms 25, as illustrated in Figure 2. These collars are in turn secured by suitable set screws 28. A stop bar 29 is slidably mounted on the rods 17 and extends transversely across the path of sheets delivered by the cords 14 between the tapes 18 and cords 22.

At the side of the frame 16, which is adjacent-to the receiving end of the toboggan 12 and extending longitudinally-0f the rod .17 and tapes 18, is a shaft 30 driven from any-suitable source by a sprocket chain 31, passing around a sprocket wheel 32 on the rear end of said shaft. The shaft 30 is provided with a keyway 33 and slidably mounted on said shaft is a suction head 34 carrying akey 35 slidably engaged in the key 33.

The suction head has longitudinal. lines of suction openings 36 through its periphery, which openings communicate with longitudinal bores 37 that open through one end of the head and these bores 37 in turn communicate through ports 38 with an inner set of longitudinal bores 39-, also opening throughthe same end of the head. This end of said head is provided with a reduced gudgeon 40 rotatablein a collar 41, the gudgeon being he'd in place by lock nuts 42. The collar 41 has an ofisetneck 43 slidably mounted on a guide rod 44v and said collar furthermore has a tubular stem 45, the bore 46 of which is in communication with a port 47. The open ends of the bores 39 successively pass the port 47 and when in line therewith the open ends of thebores or chambers 37 are closed bythe collar.

Connected to the stem is a suction tfibe The arms 25 are slidably against a cam 58.

48 leading to a suitable suction fan 49. In this tube is a controlling valve, shown in detail in Figures 4 and 5.- Said valve includes a casing 50 with a transverse passageway- 51 therethrough, with a valve chamber or bore 52 intersecting said passageway. In

cam 58 is carried by a shaft 59 on which is a sprocket wheel 60, and this sprocket wheel is engaged by an endless sprocket chain 61 leading from a suitable driving sprocket wheel 62 carried by a drive shaft 63. By using sprocket. wheels 62 of different diameters, obviously the speed of the shaft 59 and cam 58 can be varied.- A plate 64 overlies a portion of the suction head, as clearly shown in Figures 1, 2 and 7.

In the operation of this device, when the valve 53 is closed the suction head will be inactive, although it will be rotated. During this inactive period, a sheet delivered by the cords 14 will be caught by the rollers 24 and cords 22 and delivered on to the rods 17 and tapes 18. The sheet will thus be carried in a direction longitudinally otthe axis of rotation of the suction head, with one margin over said suction head, until its movement is-stopped by the bar 29. When the sheet reaches this position, the cam 58 will move to a position to cause the valve 53 to open, thereby causing a withdrawal of air through the pipe and the uppermostbores 37 and 39 of the suction head,1 thus creating suction-through the uppermost ports 36 and obviously successively through the succeeding ports 36 as they reach their uppermost position. As a consequence the direction of the sheets will be at right angles to its original'delivery'movement and said sheet passing ovcrthc plate 64 will be moved to thetoboggan 12 and carried by the tapes 13 thereof to the second machine 9. As soon as a sheet has passed from the suction roll the valve 53 will again move to its inactive position. thus cutting off suction through the head, whereupon another sheet will be de-' livered over said head and the above operation repeated.

From the foregoing, it is thought that the construction, operation and many advantages of tlie herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to-without departing from the spirit or sacrificing any of the advantages of the invention.
