WOOD NEWSPAPER MACHINERY CORPORATION, OF NEW YORK, N. Y., A CORPORA- TION OF VIRGINIA.

WEB-FEEDING DEVICE.

Application filed August 7, 1913.

To all whom it may concern:

Be it known that I, HENRY A. WISE 001), a citizen of the United States, residing at New York, in the count of New York and State of New York, have invented a new and useful Web-Feeding Device, of which ing drawings in which Figure 1 is diagrammatic view showing how a plurality of webs can be controlled and fed in accordance with this invention; Fig. 2 is a plan showing the web passing over one of the propeller rolls and means for controlling it in accordance with this invention; Fig. 3 is an elevationof a portion of the same on enlarged scale, parts being shown in central longitudinal section; Fig. 4 is an end elevation thereof; Fig. 5 is a sectional view on the line 5-5 of Fig. 3; Fig. 6 is a view similar to Fig. 3, showing the controlling mechanism for a single web. Fig. 7 is a sectional view on the line 77 of Fig. 6; Fig. 8 is. a plan of one of the gulding rolls and connecting mechanls m; and Fig. 9 is a sectional view on the line 99 of Fig. 7 on enlarged scale.

Heretofore in paper feeding devices of this character devices have been used in connection with the drag roll for aiding in keeping a plurality of webs taut ing them one way or, another. One difficulty with this system is that in running two or more webs over a drag roll in this way,

if one of them is running out of true in one direction and another in another direction,

the necessary adjustment to remedy the defect of one will increase the defect of the Specification of Letters Patent.

other. Moreover, any adjustment for the purpose of remedying a defect of one webwhen another web is running true will obviously bring the other web outof true. This invention is designed mainly to overcome these difliculties.

Referring now to Fig. 1', particularly, it

will be seen-that the invention is shown as applied to a web press having four sets of printlng couples 10 and 10 The web introduced into each couple is shown as being laid smoothly over the surface of the first impression cylinder before printing by the use of a bending roll 11. This deflects the web away from the printing cylinder toward the impression cylinder just before the web engages the type. V

Two rolls 12 and 13 are provided between the first and second couples of each printing mechanism so located as to bend the web around the first impression cylinder a slight around part of the impression cylinder and to draw away from the printing cylinder immediately after the impression.

The roll 12 which comes in contact with the freshly printed side of the web has a circumference equal to the length of an impression or a printed product, that is, one half of the effective circumference of the plate cylinder. It will be understood, of

.course, that it may have a circumference equal to any even multiple of one half the length of a printed product, or of a complete set of plates. Thus, the inked impressions deposited on this roller always register and they cannot be transferred to blank spaces or margins. These rolls are also arranged so as to bring the web into contact with the impression cylinder of the second couple besecond couple the web passes to a roll 14 which also keeps the web away from the printing surface as it leaves the second couple and increases the wrap around the impression cylinder after printing. These thus constitute guide rolls which prevent 'fore it enters the type thereof. From the outer and wrinkles in the web and insure the laying of the web smoothly on the impression cylinders, both before and after printing. The guide or bending roll 14 is of the same size as the roll 12 and for the same reason. The same is true of a second bending roll 15. From the bending roll 15 the web passes over a bending roll 16, a propeller roll 17, compensating roll 18, and a drag roll 19. All these rolls are shown also of the same diameter as the roll 12, or satisfy the principles described in connection with it, and for the same purpose.

In Fig. 1 the web is shown as slit into two parts by a slitter 20, each part of the web passing to a diflerent propelling roll 17 and each one being operated in the same way. The drag roll is. also shown as provided with a slitter 21 for an obvious purose.'

p The four propeller rolls shown in Fig. 1 are shown as arranged conveniently so that the two central ones are near each other and the webs passing over them are controlled bya mechanism supported by a single set of bearings. The two outer ones are provided with controlling mechanisms, separate, of course. The description of the double controlling mechanism coiiperating with the two central propelling rolls will serve to show the arrangement and operation of the other two sets.

Referring now to Figs. 2, 3, 4 and 5, it will be seen that the frame of the machine is provided with a pair of brackets 25. These brackets support a plurality of shafts comprising a series of hollow tubes 26 and an inner rod 26*. In thesefigures there are ten 1 of these shafts each one located loosely with respect to those outside of it so that each one is capable of turning independently of the other Each inner one projects at each end beyond the next one outside. For the purpose of turning them each one is provided on one projectingend with a collar. 27 and with a screw 28 for securing the collar to its end.

From each collar extends a radial arm 29. Each of these arms is provided with a screw 30 and with a hand wheel fixed on the screw. In the. form shown the arms are arranged alternately; that is, the arms of every alternate shaft extend downwardly Those which ex- I and the others upwardly. tend upwardly also are arranged alternately in another respect, that is, the screws are arranged on opposite sides alternately for the purpose of economizing in space. The screws also are arranged difi'erently on opposite sides, I those on one side pressing against a horizontal bar 33 and those on the other side screwing into this bar. This bar is mounted on a palr of arms 34 which ex-' tend upor down as the case may be. The inner arms 34 are linked together by a tie rod 38 passing through and secured to legs 39 on arms 34.

The bar 33 is of a length, between shoulders, equal to the combined widths of the several arms and filling pieces 35 located between them. One end of it passes through the outer arm 34 and is threaded and provided with a hand wheel nut 36 which can be screwed up to secure the several arms in their adjusted positions and prevent their jarring and working loose. The other end is secured to the inner arm 34.

On the bracket 25 are a pair of projections 40 each having a boss 4l-thereon, provided with a pair of pin holes 42. The arms 34 are centered on the shafts and each of the inner ones has an arm 45 projecting therefrom. These arms 45 are provided with spring-pressed pin handles 46 adapted to enter either one of the pin holes 42 to hold the arms 34 in either of two positions.

Each of the shafts 26-26 is provided at its outer end where it projects beyond the end of the next larger tube with a circular split collar 50 secured to the shaft by a clamping bolt 51. Extending out from this collar are a pair of arms 52 to which are secured by bolts 53 a stud 54. This is provided with a bearing surface and with ballbearings 55 for supporting a guide roll 56 in such a Way that this roll will be free to turn with a minimum of friction. The particular construction of this roll will not be described in detail as it does not constitute a part ofthis invention but it is provided with a circumferential recess in which are fixed a number of circular leather disks 57. lit will be seen that each of these rolls, being entirely free to rotate, can serve for increasing or decreasing the Web and the propelling roll, the web running between the propelling roll and the leather disks. These rolls are arranged as indicated in Fig. 2 and run in the several margins of thesheet, five of them being shown in this case.

The drag roll 19 is also provided with a plurality of freely rotating guide rolls 58 similar to the rolls 56 and controlled in a similar way for the purpose of controlling the plurality of webs after they have been brought into registration with each other.

When it is desired to change the direction of a web the side which is intended to be speeded up is given additional friction by friction between the forcing that guide roll 56 against the web i with more pressure. ing the hand wheel the hand wheel 31 which corresponds with This is done by loosenthat guide roll to'secure the desired result.

This causes that part ofthe webto be speeded up more nearly to the circumferential speed of the propeller roll, and changes the direction of the web slightly. This shows why these rolls are called guide rolls.

36 and then adjusting The rolls intermediate between the edge margins are also adjusted in a similar way if that is necessary. When this is done, the hand wheel 36 is again tightened up to hold the parts against accidental loosening. When it is desired to prevent feeding altogether the pins 46 are withdrawn and the whole device turned back out of contact with the web.

The above description applies to the double construction shown in Figs. 2, 3, 4: and 5 and the single construction shown in Fig. 6'which is of the same character except that it has only half the tubes and adjustments. It will be seen from this description that the operator has absolute control of each Web individually and can bring all the webs into proper condition before they reach the drag roll 19. Consequently, the difficulties mentioned at the beginning of the specification are entirely avoided and all the webs can be kept taut and accurately registered. Moreover, if one of the webs tends to get out of adjustment it does not affect the others and the rectifying of this difficulty does not affect the adjustment which may have been provided for the other webs. It will be seen also that by running the several propelling rolls 17 at a speed a considerable percentage above web speed and applying this individual adjustment, no difficulty is encountered from the fact that the several webs as they pass over the drag roll run at slightly different speeds owing to the increased diameter which the outer webs have under them on account of the thickness of the webs below.

Although I have illustrated and'described a detailed embodiment of the invention, I am aware'of the fact that many modifications can be made therein and that the invention can be carried out with many changes in details of construction without departing from the scope thereof as expressed in the claims, therefore, I do not wish to be limited in these respects, but
