SPECIFICATION forming part of Letters Patent No. 794,578, dated J uly 11, 1905.

Application filed March 4-, 1898. Renewed November 8, 1904. Serial No. 231,955.

To all-whom it may concern:

Be it known that I, HENRY A.VVISE VVooD, a citizen of the United States, residing at New York, in the county of New York and State 5 of New York, have invented a new and useful VVeb-Supplying Device for Printing-Presses, of which the following is a specification.

The object of my invention is to provide a web-printing press with improved web-sup- 1o plying devices arranged to automatically bring a fresh roll into position to cooperate with the feeding-in devices of the press, so that a fresh web can be introduced without stopping the press.

To these ends my invention consists of the parts and combination of parts, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is 2 a side view, partially in section, illustrating a web-supplying device constructed according to my invention. Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a sectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a detail view to be hereinafter referred to. Figs. 5 to 7, inclusive, are diagrammatic views illustrating the operation of the device; and Fig. 8 is a side view, partially in section, illustrating a modified form 3 of construction.

In the ordinary forms of web printing presses now employed for printing newspapers or similar products a web-roll is usually mounted in bearings on the side frames of the press and is provided with suitable tension devices for preserving the proper tension of the web while the same is being drawn into the press. When a web-roll is nearly exhausted, it is now ordinarily the practice to 4 stop the press in order to permit the expiring web to be severed, to remove the stub or expired web-roll from its hearings in the side frame, then to mount a fresh web-roll in the bearings, and to paste the end of the fresh web to the end of the expiring web, so as to permit the end of the fresh web to be drawn through the machine. These operations have heretofore ordinarily been performed by web-roll which is nearly exhausted. The

feeding-in devices may be of the ordinary or approved construction, comprising a feedingin drum cooperating with suitable feedingtapes,which unwind the web, as required in the operation of the press. The feeding-in device is preferably mounted in overhanging main frames of the press, and below the feeding device I provide a framework for supporting a plurality of web-rolls. The side frames of this framework are preferably provided with inclined tops for supporting the shafts of the web-rolls. Mounted in the framework are suitable sprocket wheelsand chains, having open boxes or forks for engaging the web-roll shafts. Turning with one of the sprocketwheels is a stop-disk, and cooperating with the stop-disk is a brake-lever having an abutment for engaging suitable stops or projections on the stop-disk to hold the desired web-roll in position to cooperate with the feeding-in device of the press. When the brake-lever is released or moved out of engagement with the stop-disk, the weight of the web-rolls will cause them to roll down on their inclined supports until one of the abutments of the stopdisk again engages with the brake lever. The motion or travel of the web-rolls down their inclined support can be accurately con trolled by varying the pressure exerted on the brake-lever. Connected with and actuated from the brake-lever I provide connections for severing the expiring web and for tucking the end of the fresh web into the feeding-in device. If desired, I may provide also an automatic pasting mechanism for depositing paste upon the end of the fresh web, so that the same will. be automatically fastened to the expiring web.

Referring to the drawings and in detail, A designates one of the overhanging side frames of a printing-press. Journaled in the side frames A is a feeding-in drum 10, cooperating with which are the ordinary tapes 11, which pass around the tape rolls 12. A framework B, as indicated by dotted lines in Fig. 1, is located beneath the overhanging side framesA in position to support a pluralityof web-rolls. As illustrated, the framework B forms an inclined support for three web-rolls, a fresh Web-roll being indicated by the reference-numeral W the web-roll from which the web w is being drawn into the press being indicated by W and an expired web-roll being indicated by 'W. The shafts 13 of the web-rolls W, W, and W rest upon and are supported by the side frames B. Secured upon the shafts 13 I provide gears 14, which are arranged to engage suitable tensioning and registering devices, as hereinafter described.

Mounted in the frames B are sprocketwheels 15, which carry sprocket-chains 16. Carried by the sprocket-chains 16 and supported by ledges 170, as most clearly shown in Fig. 3, are open boxes 01" forks 17. Turning with one of the sprocket-wheels 15 is a stop-disk 18, having abutments or projections 180.

A brake-lever 19 is journaled in the framework B and is provided with a catch or abutment 190 for engaging the stops 180 of the stop-disk 18. By means of this construction it will be seen that when the brake-lever 19 is raised out of engagement with the stop-disk 18 the web-rolls will move down their inclined support through the influence of gravity un til the brake-lever 19 is again brought into engagement with the stop-disk 18. This motion or transfer of the web-rolls can be accurately governed by varying the pressure exerted upon the brake-lever 19.

The tensioning and registering devices cooperating with the gears 14 of the web-roll shaft 13 are most clearly illustrated in Figs. 1 and 3. As shown, a gear 20, having flaring guides or flanges, is secured upon a shaft 21, journaled in one of the side frames B. A disk is secured on the outer end of the shaft 21, and a friction brake or strap 22 is arranged to engage with the disk, the friction between the disk and strap being capable of adjustment by means of a hand-wheel 25. This handwheel is fitted upon a shaft the-end of which is threaded into the projecting end of one brake-strap and which fits loosely in the other brake-strap, a collar being also arranged on said shaft to bear on this brake-strap. By thus turning the hand-wheel 25 the brake can be adjusted. The shaft 21 can be slightly ported in place on the tucker-blade 34.

shifted longitudinally to bring the web-roll into alinement with the printing-press by means of a threaded bolt connected to the friction-strap 22 and provided with a hand-wheel 23. This shaft is threaded into the frame, as shown, and the brake-shoes are loosely hung thereon between said hand-wheel 23 and a collar secured on said shaft. By turning the hand-wheel 23 it will be seen that the brakeshoes, and thereby the shaft 21, will be moved axially. This will also move the gear 20 axially, and by means of the flanges on the side of said gear the gear 14, and thereby the webroll-W, can be adjusted axially. This adj ustment is a slight one that is, it is used only to adjust the web-roll so that the web will assume the proper lateral position in the printing-press.

A link 26 connects the brake-lever 19 with an arm 27, extending from a rock-shaft 28, journaled in the frames A. Secured upon the rock-shaft 28,.outside of the framework A, are arms 29. Extending down from the arms 29 are arms 30, carrying a pasting-roller 31, which cooperates with a paste-fountain 32. The shaft of the paste-roller 31 is mounted in suitable slots or guides 33 in the side frames A, so that said paste-roller will move in a curved path to properly deposit paste upon the end of a fresh web, which may be sup- The tucker-blade 34 is carried by curved arms extending down from a rock-shaft 36. A latch 41 is arranged to hold the tucker-blade 34 down in its normal position against the tension of a spring 37, which normally tends to throw the tucker-blade up into engagement with the feeding-in device. A pawl 40 for releasing the latch 41 is journaled on one of the arms 30, as most clearly illustrated in Fig. 4. To restore the tucker-blade to its normal position after the same has been brought into operation to tuck the end of a fresh web into the feeding-in device, I provide a slotted link 38, which extends down from. one of the arms 29 to engagea pin carried by an arm 39, extending from the rock-shaft 36. When the arms 29 are in their raised position, the tailpiece of the pawl 40 will engage with a stop 42 to release the latch 41, so that said latch may hold the tucker-blade in its normal position until the operation of said tucker-blade is again required. A pivoted knife or websevering device 43, which is normally held out of engagement with the web w by means of a spring 44, is arranged in the path of the tucker-blade, so that when said tucker-blade is thrown up by the operation of its spring the knife 43 will be brought into engagement with the web of the expiring web-roll, so as to cut off or sever the expiring web.

A chain 16 and set of boxes 17 are preferably arranged at each side or on each frame of the machine, so that the shafts 13 of the web-rolls will be controlled from both sides.

IOO

The operation of a web-supplying device for printing presses as thus constructed is most clearly illustrated in Fig. 1 and in the diagrammatic views of Figs. 5 to 7. In order to replace an expiring Web-roll with a fresh web-roll, the brake-lever 19 will be raised, so as to move its abutment 190 out of engagement with an abutment 180 on the. stopdisk. When the brake-lever 19 is raised to its highest position, as illustrated in Fig. 6, the paste-roller 31 will bemoved down, so as to deposit paste on the end of the fresh web carried by the tucker-blade 34. As the brakelever 19 is moved down to the position illustrated in Fig. 7 the paste-roller will be moved up, so that the pawl 40 will release the latch 41,and the spring-actuated tucker-blade will insert the end of the fresh web into the feeding device of the press, at the same time operating the web-severing device to cutoff the expiring web. When the brake lever 19 again resumesits normal position, the slotted link 36 will draw the tucker-blade back to its normal position, and the latch 41- will be released, the parts again assuming their normal position, as illustrated in Fig. 1. It will thus be seen that by manipulating a single lever an expiring web-roll can be removed, a fresh web-roll brought into position to cooperate with the feeding-in devices ofa press, paste may be deposited upon the end of a fresh web, which will then be properly inserted into the feeding-in device of the press, and the expiring web will be severed or cut oif.

A device as thus'constructed is substantially automatic in action, since when the lever 19 is once raised to its highest position to release the disk 18 the parts will all automatically operate and be restored again to their normal position, as the lever is brought back to its normal position pressing on the disk 18.

In some cases I contemplate simplifyingmy web-supplying device for printing-presses by dispensing with the automatically acting paste-roller, and I have illustrated such a construction in Fig. 8. Referring to said figure, A designates one'of the side framesof a printingepress. Journaled in the side frames A, as heretofore described, is the usual feeding-in drum 10, cooperating with which are' the tapes 11, passing over the tape-rollers 12. Instead of employing separate side frames to form a support for the web-rolls the side frames A may be extended, as at A. The upper edges of the extending parts A are inclined to form a support for the shafts 13 of the web-roll W, from which the Web 1.0 is being drawn into the press and of the fresh webroll W. Mounted in the extensions A of the side frames A are the sprocket-wheels 50, carrying the chains 51, which chains 51 are provided with the open-topped boxes or forks 52, substantially as hereinbefore described.

expiring web will be severed.

Secured upon the sprocket-wheel shaft, near the end of the press, is the stop-disk 53, cooperating with which is the brake-lever 54. A link 55 forms a direct connection between the brake-lever 54 and the tucker 56. A websevering device or knife 57 is located in position to be operated by the tucker 56 and is normally held back out of the way by means of a spring 58. By raising the brake-lever 54 the web-rolls'will be released, so as to roll down their inclined support, while at the same time the end of the fresh web will be introduced into the feeding-in device and the The sid e frames A are preferably provided with bearings 59 for supporting the shaft 13 of an expired webroll until it may be convenient to remove the same from the press. It' will be seen that this form of web-supplying device for a printingpress is simple in its construction and positive in its action, and in many instances I preferably employ the same, as paste may be.

readily applied to the end of the web to be inserted when the end of the same is connected to the tucker-blade.

I do not broadly claim in this case mechanism for inserting the end of a fresh web and discontinuing the supply of web from an expiring web-roll, as this is claimed broadly in my companion case filed on even date herewith, Serial No. 672,555. 7
