SAMUEL G. GOSS, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE GOSS PRINTING PRESS COMPANY, OF SAME PLACE.
FOLDING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 569,917, dated October 20,1896. Application filed May '7, 1895. erial No. 548,451. (N0 model.)
To aZZ whom, it may concern.-
Be it known that I, SAMUEL G. Goss, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fold-Creasing and Fold-Laying Devices in Printing-Presses, of which the following is a specification, reference being had to the accompanying drawings,in which Figure 1 is a front elevation. Fig. 2 is a side elevation. Fig. 3 is an enlarged detail, being an end view of one of the fold-creasing and fold-laying shields. Fig. 4 is a detail showing the fold-creasing and fold-laying shields spread apart; and Fig. 5 is a modification, being a front elevation showing rollers instead of the fold-laying shields.
My invention relates to devices for creasing and laying the longitudinal fold of the web in webperfecting presses, and its principal object is to provide new and improved devices for laying and creasing said longitudinalfold.
Anoth er and further object of my invention is to providemechanism by which the position of the fold-laying and fold-creasing devices, with reference to the apex of the V- shaped former, may be adjusted, whereby the smooth and proper laying and creasing of said fold is greatly facilitated and crumpling and tearing of the paper along the fold prevented.
Another object of my invention is to provide mechanism or means by which the central margin of the web to be folded may be easily and readily made to follow exactly the point of the former. It is well known that when the paper which is used in the web-perfecting presses is wound upon the rollers at paper-mills the rolls are not always evenly and regularly wound. This is due sometimes to slightly-varying thicknesses of the paper and sometimes to slightly-varying tension of the web and to numerous other causes. As a result of this uneven winding of the paper it frequently happens that when the printed web passes down over the former the central medial line of the web along which the fold is to come will not always coincide with or lie exactly upon the point of the former, but will be thrown a little one side or the other of the said point; and it is one of the objects of my invention to provide mechanism by which this may be corrected.
I accomplish these objects as hereinafter former, which, being of the usual and ordinary form, construction, and operation, need not be particularly described.
2 indicates a carriage composed of a base 3 and uprights 4. The base of the carriage 2 is channeled so as to rest upon the crosspiece 5 of the folder. The base 3 of the carriage 2 is provided with a slot 6, through which a set-screw 7 passes into a threaded opening in the cross-piece 5.
- 8 indicates an upright formed integral with or secured to the cross-piece 5.
9 indicates an ad j usting-screw which passes through the upright 8 and into a suitable threaded opening in the base of the carriage 2.
10 indicates a collar which is secured upon the adjusting-screw 9 between the upright 8 and the carriage 2. It is obvious that, the setscrew 7 being loosened when the adjustingscrew 9 is turned, the carriage 2 will be moved to one side or the other, and then fixed in the desired place by means of the set-screw 7.
11 (see Fig. 2) indicates a carriage mounted upon a cross-piece 12 of the folder upon the opposite side of the former 1 from the carriage 2. The carriage 11 is in all respects like the carriage 2, above described, and mounted upon the cross-piece in the same way and moved from side to side by an adj usting-screw 13, in the same way as the carriage 2, above described.
14 indicates pulling-rollers journaled in the cross-pieces 5 and 12, below the apex of the former 1, and adapted to pull the web 15 downward over the former.
16 indicates one of the rollers of the folder, which may be of any approved form and construction.
17 18 indicate shafts which are journaled in the uprights of the carriages 2 and 11, one on each side of the former 1 near its apex.
19 20 indicate shields of spring metal, which by means of brackets 21 are keyed to the shafts 17 18, respectively. The opposing surfaces of the shields 19 20 are convex in shape and of approximately the shape shown best in Fig. 3, and are so adjusted upon the shafts that when the lever 22, hereinafter described, is lowered to bring their lower surfaces together the shields will contact one another at their lower opposing surfaces, as is shown in Fig. 1. Their upper portion is so curved that they may be opened in the position shown in Fig. at without eomin g in contact with the former 1.
22 indicates a hand-lever which is keyed upon the outer end of the shaft 17.
23 2% indicate arms which are secured, by set-screws or in any other appropriate manner, upon the shafts 17 18, respectively, near the outer ends of said shafts. One of said arms is provided with an elongated opening or slot 25 near its inner end, and a pin 26 passes through the other arm near its inner end and through the slot 25. As the handlever 22 is turned, the shaft 17 will be rotated, which rotation is communicated through the arms 23 24: to the other shaft, 18, thus moving simultaneously the shields 19 20 toward or away from each other into the respective positions shown in Figs. 1 and 4.
The plates 19 20 are provided with avertical slot 27, extending a suitable distance upward from their lower edges upon a line just inside of a line vertically below the point of the former 1, and consequently inside of the folded edge of the web 15, as is best shown in Fig. 2. Those portions of the shields between the slots 27 and the outer edges of the shields are bent slightly away from the rest of the surface of the shields, as is best shown in Fig. 3, so that said portions, when the shields are in place, will approach each other a little more closely than the portions of the shields upon the other side of said slot. This portion of the shield normally has the position shown in Fig. 3, but when said shields have their lower portions brought into surface contact, or nearly so, by the hand-lever 22 the projecting portions of the shields are forced backward, thus causing a greater pressure between their surfaces, and consequently upon the folded edge of the web which passes between them, than there is between the other parts of their opposing surfaces.
28 indicates a collar, which is secured by a set-screw upon the shaft 17, as is best shown in Fig. 2.
29 indicates a spiral spring a suitable distance behind the'upright i, which is mounted on the shaft 17. One end of the spring 29 enters a suitable socket in the collar 28 and the other a suitable socket in the upright 4. A similar collar and spring are placed upon the-shaft 18, which, being exactly like the collar and spring above described and mounted in the same way, are not shown or further described. The tension of the springs is such as to cause the shafts 17 18 to rotate so as to move the lower portions of the shields toward each other into the position shown in Fig. 1
and to hold them in that position, the tension of said springs and the consequent bearingpressure by the shields upon the web that passes between them being regulated by adjusting the collars upon their respective shafts by means of the set-screws.
The operation of my device is as follows: The web being brought down over the former is brought between the shields, which are opened as shown in Fig. 1. The web is then brought down between the pulling-rollers 11 and passed into a folder of any suitable or preferred construction, one of the rollers of which is indicated by the numeral 10 and which operates to again fold the sheet after it has been folded by the former and shields before described. The shields are then closed upon the web, their pressure upon the fold being regulated by adjusting the tension of the springs, as above described, and the ma chine set in motion. The pulling-rollers pull the web between the shields, which act as guides for the surface of the web over the former and crease and lay the fold. The position of the shields is adjusted by moving the carriages to the right or left, as may be desired, by means of the adj Listing-screws 9 and 13.
Fig. 5 shows a modification of the foldcreasing and fold-laying devices. 30 31indicate rollers mounted upon shafts 32 33, respectively, carried by the uprights 4 at of the carriages 2 and 11. The carriages are mounted upon the frame in the same manner above described. One of the uprights 4 of the carriage 2, in front of the former, has a slot 34E near its top, as shown in Fig. 5. 35 indicates a sliding block mounted in the slot 3 1. The shaft 33 is journaled in the sliding block 35. 36 indicates a compression-spring interposed between the sliding block 35 and the side of the slot 3i and operating in its tension to yieldingly hold the roller 31 against the roller 30 with sufficient force to draw the web 15 downward over the former and crease and lay the longitudinal fold therein. The rollers 30 31 are of course driven in any ordinary and usual manner.
By means of the adjustable carriage, acting as above described, the rollers may be adjusted with reference to the apex of the former and insure the proper longitudinal folding and creasing of the web 15.
hen the pressman in charge of the press observes that the central medial line of the printed web, owing to the causes heretofore recited, does not coincide with the point of the former, but lies a little to one side or the other of it, by giving a slight adjustment of the carriage either at the front or the rear and to one side or the other, as the circumstances of the case require, the difficulty will at once be automatically adjusted and the central medial line of the longitudinally-folded web will be brought directly over and coincide with the point of the former. The adjustment may be made by moving the carriage at the front or at the rear of the foldlaying devices, according to circumstances, and the amount of adjustment is ascertained by experiment and experience, as it will vary with the different circumstances of the case, but will be easily apparent to an experienced pressman.
That which I claim as my invention, and desire to secure by Letters Patent, is
1. The combination with a frame, and a former, of carriages mounted 011 said frame and laterally adjustable thereon independently of each other, means for independently adjusting said carriages laterally relatively to the discharge-point of the former, and foldlaying devices mounted in said carriages, substantially as described and for the purpose specified.
2. The combination with a former, of foldlaying shields journaled on suitable supports one 011 each side of said former, near its apex, springs operating normally to yieldingly hold said shields in contact with one another at their lower opposing surfaces, and mechanism adapted to draw a web over said former and between said shields, substantially as described.
3. The combination with a former,carriages mounted on suitable framework below said former, and means for adjusting the position of said carriages laterally, of curved fold-laying plates journaled on said carriages one on each side of said former near its apex, springs operating normally to yieldingly hold said plates in contact with one another at their lower opposing surfaces, and mechanism adapted to draw a web over said former and between said plates, substantially as described.
4. The combination with a V-shaped former, of curved fold-laying plates located one 011 each side of said former near its apex, said plates being vertically slotted upon a line interior to the apex of said former, and having the portions exterior to said slots bent away from the rest of the surfaces of said plates and toward each other, and mechanism adapted to draw a web over saidvformer and between said plates, substantially as described.
5. The combination with a V-shaped former, of curved fold-laying each side of said former near its apex, said plates being vertically slotted upon a line interior to the apex of said former, and having the portions exterior to said slots bent away from the rest of the surfaces of said plates and toward each other, means for adjusting said plates, and mechanism adapted to draw a web over said former and between said plates, substantially as described.
0. The combination with a V-shaped former, carriages mounted upon suitable supports below said former, and means for adjusting the position of said carriages laterally, of shafts journaled in side of said form er and near its apex, a handlever keyed upon one of said shafts, arms connecting said shafts, fold-laying shields keyed upon said shafts, springs bearing upon said shafts and adapted normally to yieldingly hold said shields in contact along their lower opposing surfaces, and mechanism adapted to draw a web over said former and between said shields, substantially as described.
