To all whom it may concern:-

Be it known that I, VlLLIAM EvENsnN, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain newv and use ful Improvements in PrintngPresses, ot which the follow-ing is a specification, ret`- erence being had to the accompanying drawings This invention relates to printing presses, and has for its object to provide a safety device by the operation of which the folding mechanism `is prevented from being choked up and broken by wrinkled or torn paper. I accomplish this object by the means illustrated in the accompanying drawings and4 'right in said figure. Fig. 3 is atop View of the preferable form of my` safety device.

Referring to the drawings :-5 indicates the` framework of the machine, adjustablymounted in which in any well-known manner are the ordinary pulling and creasing` rolls G-T, down between which projects the point of the ordinary former 8. 9 indicates the rotary carrier of any well-known form of folding mechanism, and .10 indicates a cutting cylinder coperating therewith. Inasmuch as all these parts are of the ordi-V nary construction and operation and form no part of my present invention, it is believed that no further description of the same is required.

llieferring now to my improved safety device and the manner in which it is mounted in the framework of the machine in the construction shown, ll indicates a standard screw threaded into the framework 5 of the machine.

12 indicates my improved safety device or shield, being in the construction shown fanlshaped, strengthened by lucans'ol' ribs lil, and provided at its smaller end with a slot 1,4.

be passed through the slot 14 in the shield and Secured in a screw-threaded opening in the top of the standard 11.

15 indicates a screw which is adapted to4 As seen in Fig. 2, the wider end of the shield 12 projects to within a very short distance tfrom the former 8, the distance therefrom being adjustable by means of the slot 14, as will be understood. at which the shield stands relative to the former can ofV course be regulated as, desired by means of washers of various sizes on the screw 15, below the slot 14, a washer 16 being shown in the drawings in position on the screw.

It has been found in practice that. when the web of paper breaks in the printing press and comes down over the former in a broken or wrinkled conditiom the shield 12`operates to strip the paper from the point The height` of the former and prevents the torn or` wrinkled paper from passing. between the rolls 6 7 and thence down into the foldn ing mechanism where it would be likely to choke up the folding mechanism and possibly break the same. It has been found' also that with the shield 12 in properly adjusted position relative to the former it is impossible for a' pressman to lead the web of paper-between the rolls 6--7 except in proper position with the paper pulled down smooth'and tight over the pointv of the former, for the reason that when the'paper of the folding mechanism in proximity to1 the former as shown in the drawings or at any Eher Apoint along the path of travel of the web of paper, and the claims are to be .construed accordingly t0 cover this idea broadly. Moreover, I do not wish to restrict myself to the use of the single one-piece fanshaped shield shown in the drawings, except as claimed in the more specific ofthe claims hereinafter presented,

While I have shown the shield 12 positioned obliquely relative to the former 8 at an obtuse angle to the direction of the run of the paper over the former, it will be understood that I do not limit myself to thus placing the shield at an obtuse angle to the run of the paper, except as hereinafter specifcally claimed.

What- I claim as my invention and desire to secure by Letters Patent isl. In a printing press, the combination With a folding4 mechanism, of a shield located in proximity to the' run of the paper through the press in advance of the fold- -1ng mechanism and adapted to strip the paper from its path when the same becomes wrinkled or broken.

' 2. In a printing press, the combination with a folding mechanism, of a shield located in proximity to the run of the paper in advance of the folding mechanism and positioned at an obtuse angle to the direction of travel of the paper, said shield being adapted to -permit the paper when 'in nor mal unwrinkled condition to run' clear of the shield.

3. In a printing press, the combination with a folding mechanism, a former located in advance of the folding mechanism, and creasing devices cooperating with said former, of a shield projecting to within a said former.

short distance of said former and adapted to strip broken or wrinkled paper from said L former.

4f. In a printing press, the combination with a foldin mechanism, a former located in advance o the folding mechanism, and creasing devices coperating with said former, of a shield projecting toward said former andadjustable relative thereto, being adapted when properly adjusted to strip torn or wrinkled paper from said former.

5. In a printing press, the combination with a folding mechanism, a former located in advance of the folding mechanism, and creasing devices cooperating with said former, of a shield projecting toward said former at an obtuse angle to the initial direction of travel of theweb of paper over the former and adapted to strip torn or wrinkled paper from said former.

6. In a printing press, the combination with a foldin mechanism, a former located in advance o the folding mechanism, and creasing devices coperating With said former, of a fan-shaped shield presenting its Wider end toward said former and mounted adjustably relative thereto, being adapted When in properly adjusted posi* torn or wrinkled paper from tion to strip WILLIAM EVENSEN.
