11 Claims.

In ruling apparatus, particularly that of the dual L-type in which two ruling machines are employed that are located at right angles one to the other, with the second machine receiving .6. the ruled sheets from the first machine, an adjustable stop at the corner or delivery end of the first machine is usually employed, this stop being made adjustable so that it will properly position sheets of difierent sizes in relation to their 10 introduction into the second machine. In the second machine, as is Well known to those skilled in the art, guides are employed for the sheets that are moved from the first machine and are carried through the second. The adjustment of the stop 15 in the corner, or at the delivery end of the first machine has heretofore required the adjustment of the guides in the second machine, thus making an alteration a relatively intricate problem as the guides are ordinarily substantially alined with the stop. 1

The object of the present invention is to provide a structure in which the stop and therefore the guides may be relatively fixed, and to provide conveying means that is adjustable toward andfrom the stop so as to insure delivery of sheets of different sizes thereagainst. To a very great extent therefore this eliminates the necessity of an adjustment throughout the second machine.

view on the line In the structure disclosed, two machines are illustrated designated respectively I2 and I3 located at right angles to each other and each being provided with suitable pen beams or sheet marking implements designated respectively It 5 and it. These instrumentalities and the mechanisms for operating them are well known, and it is believed need no further exposition. Suitable gates, indicated at I6 and I1, serve to control the passage of the sheets to the ruling devices.

Referring particularly to Figure 4, it will be noted that the gate it and ruling devices M are located over the usual table l8 and the sheets are carried to the gate I6 and under the ruling 15 devices It by an endless cloth or belt that has an upper rearwardly moving stretch 9 operating over the table and passing around a rear roller 2|. A lower stretch 22, moving forwardly from the roller 21 beneath the table l8, extends around a series of rollers 23 at the front end of said table. Endless cords or strings 24, operating around rollers 25, have lower stretches 26 that cooperate with the stretch i9 and clamp the sheets carried by said stretch IS. The sheets that are carried by the stretch l9 of the cloth are brought around the roller 2| and are carried forwardly against the under face of the stretch 22 of the cloth. In order to maintain the sheets against said stretch 22, endless cords or strings 21 cooperate with the stretch 22 extending around the roller 2| and around a roller 28 in advance of the lowermost roller 23. The strings are guided around the roller 2| by an upper idler roll 29 and said strings are directed from the roller 28 rearwardly and downwardly by a roller 30 to another guide roller 3|, from whence said strings pass back to the roller 29.

The sheets leave the front end of the stretch 22 of the cloth and are directed by the cords 21 to another endless conveyor cloth 32 that passes around a guide roller 33 and around the front side of the roller 38. This conveyor cloth 32 has a rearwardly and downwardly moving stretch 3 3 on which the sheets are held by the cords 21, and the rearwardly running stretch 34 of this endless conveyor 32, ends at a roller 35 located below and in rear of the guide roller 3!! for the strings 21. From the roller 35 the conveyor extends forwardly in the form of a stretch 36 passing around guide rollers 31, and thence to a guide roller 38 from which the cloth returns to the roller 33. The guide rollers 31 are thus in a forwardly moving lower stretch of the cloth and a loop is formed in said cloth at 39, this loop suspending a relatively heavy take-up roller 49.

With the structure as thus far described, it will be noted that the sheets after passing the ruling devices, are thus carried forwardly between the stretches 22 of the first cloth and the underlying stretches 2'! of the strings, and that when said sheets reach the front end of the machine they are again turned downwardly and rearwardly and rest upon the stretch of the cloth 32, being held thereagainst by the strings '21. The sheets are delivered from the stretch 34 of the cloth at the roller 35 and in order to insure this delivery, rollers ii are employed that are located in rear of the roller 3t and between which the cords pass to the guide roller 3!. When delivered from the stretch 34 of the cloth they are carried by tapes 42 rearwardly until they strike a stop bar 63 placed across their path when on the tapes 62. The bar 2%, as will be noted particularly by reference to Figure 3 is mounted on the rods 44 that pass through horizontal holding guide collars t5 and these rods may be clamped by set screws 45. The stop is thus made adjustable, but for ordinary purposes, having once been adjusted, it does not thereafter have to be materially altered.

The sheets are thus delivered into the corner of the apparatus and are brought against the stop 43. From. this point they are fed into the second machine [3. For this purpose, a suction roller 41 is employed, which is operated in a well known manner periodically to move the sheets at right angles to their path of delivery against the stop 43 and carry them to an inclined conveyor 8 that delivers them. to the gate ll of the second machine, this gate operating er odically in a manner well understood. From this gate they move under the ruling devices lb of the second machine, being carried by an endless cloth 49. Cooperating with the upper stretch of this cloth are endless cords be that hold the sheet thereupon, and cooperating with the forwardly moving stretch 49 are other cords 59 that deliver the sheets to a lower second cloth arranged much on the order of the cloth already described. Cooperating with the clot 52 are stretches of the cords 5!, and this cloth and the cords deliver the ruled sheets to rollers 53 that in turn discharge them into a layboy 5 The cloth 52 instead of being kept taut, as is the cloth 35 by a Weighted take-up roller passes around a roller 55 which as shown in Fig we 11 has mountings in adjustable boxes 56. These are engaged by adjusting screws 5?,

Referring now again to the first machine, and particularly the delivery end of the stretch 34 of the cloth 32 with respect to the stop 43, instead of it being necessary as heretofore to adjust this stop it to various sizes of paper, the delivery end of the cloth 32 is adjustable toward and from this stop by making the roller 35 transversely adjustable. Means in the present embodiment for effecting this is shown more particularly in Figure 7. The roller 35 around which the cloth 32 passes, has bearings in boxes 58 carried by the ends of horizontal racks 59. These racks are slidable in guideways mounted on the frame of the machine by brackets 65. Journaled in said brackets is a shaft 62 having a suitable handle 63. The shaft carries pinions (i i in mesh with the racks. Obviously by turning the shaft 62 the racks are moved, thereby moving the boxes 53 and carrying the roller 35 toward and from the stop 33. The roller is held in its ad justed position by any suitable means, as set screws 65 mounted in the guideways 66 and bearing against the racks. The rollers 38 and M are preferably carried by brackets 66 formed upon the boxes 58. It will be noted particularly by reference to Figure 4 that any adjustment of the roller 85 either toward the stop G3 or away from it, and which varies the length of the stretches 34 and 36 of the cloth 32, is allowed for by the loop 39 and the rising and falling of the take-up roller 48. This roller as shown in Figure 9, has its gudgeons 6i journaled in boxes 68 that are vertically movable in guideways 69.

With this structure, it will be evident therefore that having once positioned the stop bar it and alined the guides through the second machine (one of said guides being shown at it in Figure 1), sheets that are properly brought against said stop, will always pass through the second machine in correct alinement. If smaller sheets are to be ruled at any time, instead of adjusting the stop #3 and the guides through the second machine, it only becomes necessary to move the roller 35 toward the stop 43 (see Figure 4) so that the delivery takes place closer to the stop 43. If it is desired to pass larger sheets through the machine than those which have been ruled in a previous lot, the roller is moved away from the stop. Irrespective of this adjustment of the roller 35, the active stretch 34 of the cloth 32 is kept properly taut by reason of the take up roller 40.

From the foregoing, it is thought that the construction, operation and many advantages of the 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.
