1 Claim.

My invention relates to improvements in printing presses, and specifically to a printing press for manufacturing a new and novel type of stationery.

An object of my invention is to provide a printing press for manufacturing stationery, said press composed of a plurality of rotative form or type rollers for imprinting various colors on the web of paper traveling thru the machine, means for drying the ink thereon, for cutting the web into a desired size and shape of sheet, for applying glue to certain portions thereof, and for pressing said sheets and depositing them into a receptacle.

A further object of my invention is to provide a printing press assembled in two divisions, one thereof mounted on wheels and arranged to roll away from the other portion thereof, affording space thru which a workman may pass to mount and adjust the plates of type on the form rollers, to make repairs to the machine or to thread a web of paper therethru.

A still further object of my invention is to provide an ink fountain for a printing press of the class described, said ink fountain being removable from the machine for refilling or replacement, thus foregoing the necessity of cleaning the fountain while rigidly attached to the press.

A still further object of my invention is to provide a means for adjusting a form of type after said form has been rigidly secured to the form roller of the press, as a means to save time and effort in the adjusting of the plate.

A still further object of my invention is to provide a cutter and adhesive spreader for a printing press, the cutter removing alternate rectangular portions from either edge of a web, and the adhesive spreader applying adhesive substance to the remaining portion of the edge.

A further object of. my invention is to provide a means to be mounted on a printing press of the type employing roll paper as the medium on which to print, said means adapted to prevent breakage of the web of paper threaded thru the press, as so frequently occurs due to a defect in the roll causing a portion of the paper toadhere to said roll, the web breaking when excess tension is applied thereto in an effort to part the adhering portion from the roll.

A still further object of my invention is to provide a delivery means for a high speed printing press, said delivery means composed of. an endless conveyer with a plurality of vanes perpendicular thereto, a plurality of sheets of paper from the printing press positioning themselves between the vanes as said vanes are radially extending around one of the ends of the conveyer, and dropping therefrom when the vanes are again separated while traveling around the other end of the conveyer, and means to actuate the said conveyer.

These and other objects will be hereinafter more fully explained, reference being had to the accompanying drawings forming a part of this specification, in which like characters refer to like parts in the different views, and in which:

My invention herein described is adapted to the manufacture of stationery, a sheet of which is illustrated in Fig. 2. This novel type of stationery combines the conventional letter paper and envelope into one sheet, A, lines B representing the letter head printed at the top of the letter sheet, and C indicating the return address of the sender, printed on the opposite side of. sheet A. Portions D are transversely extending flaps, gummed with an adhesive substance on the letter head side of the sheet, and provide a means to seal the letter when it is folded and ready to post. The following is a description of a machine for printing, gumming and cutting sheets of this type from a web of paper unwound from a roll.

The machine consists of a mounting framework for a rotary press, a system of rollers, guides, form, and. impression rollers, cutters and ink drypress mounted on wheels.

ers, and finally, a conveyer and delivery means for the finished product. The framework is composed of two units, division S being stationary and division R mounted on wheels RI, said wheels engaging on a trackway 2, adapting section R to roll from section S, and affording space for a workman to pass therebetween. Section S provides a pair of brackets 3 and 4 mounted on vertical members 5 and 5, respectively of the framework, as supporting means for the roll of paper 6, the web 6 of which is threaded through the press. A shaft 1 extends longitudinally thru the roll 6, the projecting ends of said shaft engaging in elongated apertures 8 of the brackets 3 and 4. Bracket 3 is arranged with a cap 3 comprising. the end thereof, a pair of bolts and wing nuts 9 securing said cap in position, this providing a means to easily remove the roll of paper from the press. Bracket 4, as shown in Fig. 3, has no removable cap. Web 6' is guided by rollers l and II trunnioned on members l2 and I 3 of the mounting frame, after which, all wrinkles being removed from the web, it passes between the rollers performing the printing operation. On the type of machine which I am describing there are two of these groups of rollers. More may be used without altering the description, since they are of similar construction. I shall describe one of them briefly, describing only such members as relate to the novel features of the press under consideration.

A large impression cylinder I4 is trunnioned by means of a shaft I5 to vertical member I6 of the framework S, the extremities of said shaft [5 projecting from the said trunnions and affording mounting positions for gear wheels H and I1 rigidly attached thereto. Gear I1 is driven by member I8 which is in turn actuated by pulley wheel l9 by a belt or other means communicating with a source of power P. Impression cylinder I4 is of conventional design. The diameter thereof may be decreased or enlarged to cause firm engagement of web 6 against printing type arranged on form rollers and 20 trunnioned on a vertical member RZI of the portion of the When the two portions of the press are in engagement and are secured by means of a pawl 22 pinioned to member, SW and registering with ratchet 22' rigidly secured to member RZI, said pawl tensioned from the ratchet by an eccentric member 23 engaging against shoulder 23' rigid with the member SiB; when this or other means is used to prevent relative movement of the two press units R and S, geared members 24 and 24' mounted on the projecting shafts 25 and 25' of form rollers 28 and 20, respectively, engage with gear wheel l7, and are actuated thereby. As a means of supplying ink to the type, a pair of ink fountains are mounted on framework 26 supported by horizontal member R21. An ink fountain 28 is adapted to slidably engage onto said framework, groove 29 positioned in the end of said fountain passing over tongue member 30 integral with support 26. As a securing means for said ink fountain, a spring actuated lever 3| is pivoted to framework 26 by pin 32. Plunger 3| integral with said lever will be forced into registry with aperture 33 by spring 34 engaging between said lever and shoulder 35 integral with frame 26. It is readily seen that the ink fountain may be easily removed from the press by simply ejecting plunger 3| from aperture 33 by pressing downwardly on lever 3|, after which the ink mountain may be slid from engagement with frame 26.

Ink fountain 28 is in connection with a conventional system of ink distributing rollers 36, the last positioned ink roller 36 engaging against the type mounted on form roller 20 and assuring a fresh supply of ink to said type for each revolution thereof. Each of the form rollers is equipped with an inking means as described.

A second pressure cylinder l4, similar to cylinder i4, is trunnioned on the vertical member l6. Ink fountains 28 are supported by framework 26 mounted on the horizontal member S83, said ink fountains and the form rollers which they supply with ink, are arranged as previously described.

After passing through the second group of print rollers, web 6 enters the portion of the machine adapted to out said web into the desired shapes, apply adhesive to the edges of the sheets, dry the fresh ink and adhesive, and arrange the finished stationary in a receptacle. A slitter 3'! is rigidly mounted on a shaft 38 trunnioned on the horizontal members 39. Shaft 38 is rotated by toothed member 40 engaging with a second toothed member 4| which acts as a conveying means for power from gear wheel I? to the slitter actuating gear 4|. By means of slitter 31, web 6' is separated into two new webs 6a and 6b, 60. thereof passing along the upper horizontal member 46 and thru the edge trimmer, while the remaining portion of the web, 6b, is deflected by the roller 42 trunnioned in member 40, extends downwardly to roller 43 trunnioned in horizontal member 44, and then passes thru an edge trimmer and adhesive spreader mounted on said member 44.

The edge trimmer referred to is provided for the purpose of removing alternate sections of paper from the edges of the continuous web and leaving, as shown in Fig. 2, a small flap D remaining thereon, upon which an adhesive substance is spread for the purpose of sealing the letter. A cutter blade 45 is spirally positioned around revolving cylinder 46 trunnioned between members 41 and 41 which are in turn supported by horizontal members 40 and 40. A shearing member 48 is arranged between and integral with members 41 and 47'; it is in parallelism with cylinder 46 and one edge thereof is spaced radially from said cylinder a distance equal to the radial distance to the cutting edge of blade 45. As shown by dotted line F in Fig. 8, the web of paper, in traveling past the edge cutters must pass within the radius of the cutter blade as cylinder 46 revolves. It will be seen that a portion of the edge of the web will be sheared from engagement therewith by the action of the cutter blade against shearing member 48. A shearing action between the ends of the cutter blade and members 41 and 41', respectively, will complete the trimming of the edges of the web. Referring to Fig. 2, which is a plan view of one of the sheets of stationery, portion A from both edges of the web have been removed, leaving D remaining thereon. Now, it is desired to apply glue, mucilage, or other adhesive substance to these surfaces D. This is done by means of a box 49 supported by the member 41 and positioned immediately adjacent the edge cutter to the paper traveling thru the press. On the lower side of said box 49 is a spigot 50, said spigot being perforated with a plurality of apertures 5| on the under side thereof. Said apertures are of a sufiicient size to allow the adhesive substance to flow therethru, when aided by the surface attraction of some article engaging thereunder, but they will not allow said substance to v 2,060,809 flow freely therefrom. Box 49 'is so positioned.

that the end of the spigot 50 will extend over flap Dof the web, said portion of the web willengage under said spigot as it passes thereby, and will receive a small amount of the adhesive.

Another system of edge cutters and adhesive spreaders is positioned on horizontal member 44, parallel to which web 6b travels. Said system is similar to the one described, and performs the same operation to the said web 6b. After the trimming and gumming operation, webs 6a and 6b pass over heat rollers 52 and 52' respectively, the heating means not being shown in the drawings, but the function of which is to dry the printers ink and damp adhesive substance before the separate sheets of stationery are packed together. A pair of rollers 53 and 53 trunnioned on member 54 are arranged as a further drying means, 53 being supplied with heat, and 53 engaging revolvably therewith and functioning as a means to tension the webs 6a. and 62).

A cutting means for dividing the webs transversely into separate sheets consists of a revolving cylinder 55 trunnioned on horizontal member 56, said cylinder having a longitudinal cutter blade 55 extending from the periphery thereof, said blade adapted to shearably engage against a shearing member 56' rigid with the member 56.

The separate sheets then pass between rollers and 5i which revolve at a speed greater than that of the web, and cause each sheet to accelerate, and gain a small distance over the following sheet, after which they drop into the conveyer, between a pair of vanes thereof.

The conveyer and delivery means consists of a plurality of plates or vanes 58, each thereof equipped with a pair of lugs 59 on the opposite ends at the base of the vane, said lugs arranged with an aperture 60 therethru, as a means to receive a pin member 6| rigidly secured to the adjacent vane. Thus, pins 6| will engage thru apertures 66, a plurality of vanes may be arranged in alignment, and an endless conveyer formed thereby. Rollers 62 form the turning points for said conveyer, and the means for actuating the same is arranged as follows: A toothed member 63, rigidly secured to the shaft 62 of roller 62, is arranged in such a way that the teeth thereof engage between the extending pins 6| securing vanes 58 at the bases thereof. Shaft 62' is rotated by gear 64 communicating with a source of power, as hereinafter disclosed, and thereby toothed member 63 will actuate the vanes 58. A second toothed member 65, actuated by gears 66 and 61 connecting with gear 64 on the conveyer shaft 62', aid further in actuating the vanes, the radial teeth 65 thereof engaging against fingers 68 outwardly extending from the opposite ends of vanes 58 and transferring said vanes around the ends of the conveyer.

Now, sheets of the completed stationery will drop into the conveyer between the vanes at G. The toothed members will actuate the vanes in the direction of the arrow, the paper will be conveyed to the opposite end of the conveyer, where, the vanes separating radially will allow the sheets to escape therefrom by gravity, and be guided by inclined plane 69 into a receptacle arranged thereunder. This completes the course of travel of the web thru the press. However, certain groups of members have not been explained in detail.

Among these is the feature which prevents breakage of the web of a printing press using a roll of paper as the supply therefor, as shown in Fig. 4, which is a top view of the 'roll of paper 6 mounted by means of shaft 1 on the brackets 3 and 4 of the framework. Note that the aperture into which shaft 1 engages is elongated in shape, allowing horizontal movement of the roll. A bifurcated member H is arranged to slidably engage in a shoulder or lug l2 rigidly secured to the framework 13, the bifurcations H thereof engaging around shaft 1, as shown in Fig. 5. A spring 14 encloses shaft H and engages against shoulder 12 and an adjusting means, such as a knurled nut 15, threadedly engaging on shaft ll, said nut providing a means to vary the initial compression of spring 14. An enlarged portion ll acts to prevent the'bifurcated shaft from disengaging in shoulder 12. A similar group of members are mounted on member 13' on the opposite side of the press, the bifurcations thereof engaging around its respective end of shaft 1. However, spring 14 is of considerably less compressive strength than spring 14, either thru adjusting by means of nut '15 or the construction thereof.

Now, consider a roll of paper mounted on an ordinary press. A defect therein might cause a portion of the web to adhere to the roll longitudinally. The tension on the web caused by the pull of the impression rollers will tend to part this adherence simultaneously across the roll, with the result that the web will break due to the excessive tension. With the tensioning means above described mounted on the press, bifurcations ll will transmit a force exerted on the roll by the web to the springs 14 and 14'. Due to the difference in the initial compression of the two springs, the weaker spring 14' will be affected before the stronger 14. As a result the latter end of the roll will be resisted, a tearing action will occur between the adhering web and roll, the adherence will tend to break away, beginning at the latter end of the roll and traveling longitudinally across the roll.

As shown in Fig. 6, I have provided a means to adjust a plate of type after said plate is rigidly secured to the form roller of the press. Form roller 20 is secured to shaft 25, and said shaft projects from its trunnion, to allow engagement of the geared member 24 thereon. Said gear is concave on the inner surface thereof to accommodate plate 16, which is secured to shaft 25 by means of key 11 or other means. A spacer l8 encircles shaft 25 and engages between the trunnion thereof and the inner face of plate 16. A pair of apertures 19 is positioned in plate 16, diametrically arranged and axially aligning with annular'slotted apertures 80 positioned in gear member 24. A bolt 8| extends thru each of these pairs of apertures and with nuts 8| threadedly engaging thereon, acts as a means to securely unite the said plate and geared member. In mounting a plate of type 82 on the form roller, said plate is first axially aligned thereon, then secured thereto by conventional means. All of the plates on the press are thus secured. Then nuts 8| are loosened and the necessary circumferential adjustment of the plates accomplished by sliding plate 16 with respect to geared member 24.

It is obvious that the means of actuating the various moving members of the press as thus far described is subject to so many variations that it is needless to describe any one specific system for this purpose. Reference to Fig. 3 will show that such a system is easily designed. The gearing means operating the revolving member is shown by dotted lines. Dotted line E represents an intermittent gear arranged to engage against gear H actuating the conveyer system, and correctly timed to move said conveyer at regular intervals, corresponding to the speed with which the sheets of stationery are completed.

Although I have shown and described a certain arrangement of the members of the press, I do not wish to be confined to such an arrangement alone, since many other embodiments lie within the scope of the appended claims. Having fully described my invention, what I claim as new and desire to secure by Letters Patent In a printing press of the class described comprising a stationary frame, and a frame portably arranged to move to and from the first said frame, the stationary frame carrying a roll of paper, and means supporting the same, and adjusting means for each end of the supporting means for the roll of paper independent of each other to avoid breakage of the web of the roll of paper when excess tension is imposed thereon, a form roller carried by the portable frame in working relation to the web of the roll, ink dispensing rollers to engage with the form of the form roller, and an ink fountain to ink the rollers, and a conveyor for the web as printed.
