ceases.

To all whom chi may concern:

lie it known that l, MARTIN C. NEUNER, a citizen-of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Reinforced-Paper-Making Machine, of which the following is a specification.

This invention relates to a machine for producing reinforced paper, such, for example, as the paper shown in a previous patent of mine No. 879,533, issued February 18, 1908.

The reinforced paper, which it is the object of the present machine to produce, consists of a paper the pulp of which may be composed of any of the well known materials, and a reinforcing material which is incorporated in the pulp of the paper in such a manner that the fiber or pulp penetrate the interstices of the reinforcing material.

The reinforcing material consists preferably of a fabric having a comparatively coarse mesh, the threads of which are composed of an absorbent material so that the pulp not only penetrates between the threads of the fabric but also'is absorbed by and penetrates the threads themselves, thereby producing a paper which is much stronger than paper of the ordinary kind consisting of pulp only. The reinforcing materialmay extend through the whole area of the sheet of paper, or it may consist of a strip which is located at the particular place in the paper where the paper is to be subjected to greatest wear or strain.

I am aware that heretofore fabrics have been sized by coating with a material to render them opaque or give them a surface which can be- Written upon, such, for example, as window shades or tracing linen, but the paper produced by the present machine is essentially different from such fabrics in that the main body of the paper consists of paper pulp and the fabric which is employed as a reinforcement is inserted in the pulp while the pulp is in plastic form and spread out as a sheet so that the amount of pulp which forms the thickness of the leaf is not dependentupon the reinforcing Specification of Letters Patent.

devices.

The main object of the invention is to make it possible to produce any of the variousgrades and types of paper heretofore produced and to not change the quality of the material of which such papers are produced but to add the reinforcement to such papers without changing their appearance.

While the invention infits combination includes means for producing and forming a layer of pulp into which the reinforcing fabric is to be inserted and also includes means for finishing the paper, such pulp forming means and finishing means may be of any preferred form, such, for example, as a Fourdrinier machine. The means for placing the reinforcement in the pulp combe readily attached to machines of various widths and to provide means for accurately adjusting the device so that either a sheet or a strip of reinforcing material will be placed in exactly the desired position relatively to the Width of the paper or at the required'point between the two surfaces of the paper.

Referring to the drawings :-Figure 1 is a longitudinal vertical sectional View taken through the wet end of the machine, the paper making machine forming part of the combination comprising a machine of the Fourdrinier type. The section is taken on the line m -w Fig. 2. Fig. 2 is a plan View of the apparatus shown in Figsl, such features of the paper making machine as are irrelevant to an understandlng of the invention not being shown. This figure shows the forcing material. Fig. 3 is an enlarged plan view similar-to Fig. 2 showing the apparatus as employed for inserting a sheet of reinforcing material which substantially fills the same. area as the paper. Fig. 4 is a side elevation of the attachment, part of the bracket for supporting the idle reel being broken away. Fig. 5 1s a rear elevation of the attachment with part of the supporting tube broken away. Fig. 6 is a section on line 02 -110 Fig. 4. Fig. 7 is asection on line ww Fig. 4. Fig. 8 is an enlarged side elevation of the feeding wheel and adjacent parts, the paper pulp, screen, and rolls being in section. Fig. 9 is a plan view on a reduced scale of the feeding roll designed for placing a strip of'reinforcementin the paper, the width of reinforcement being shown by dotted lines. Fig. 10 is a perspective view of a portion of a sheet ofpaper reinforced with a strip of reinforcement, a part of the pulp being broken away to reveal the reinforcing strip. Fig. 11 is a side elevation of the remainder of the paper making machine. Fig. 12 is a section on line w m" Fig. 4.

Referring to Figs. 1 and 2, the main part 4 of the machine shown consists of the wet end of a Fourdrinier machine. .1 designatesthe wire olefin-2 the deckle straps and 3 the side bars ofithe deckle frame whlch frame, as is well known, is so supported that known, a more .detailed description is unnecessaryi The attachment, shown 1n position in Figs. 1 and 2 and in detail in .Figs.. 4 to 7 'inclusive, comprises a feeding wheel or cylinder 4 having a crowned face and mounted to rotate on a sleeve 5 which is sup rted by a bolt 6 in the lower end of two vertical frame bars 7. A plate 8 is secured to one side of the wheel 4 and is provided with teeth 9 which are adapted to engage with the reinforcing fabric and prevent slippage of the fabric. The bars 7 are attached to two frame plates 10 by bolts 10 which engage in slots 11 in the plates 10 and thus permit the bars 7 to be raised or' lowered and thereby aiford adjustment of the feeding wheel 4 to the desired elevation.

A guide finger 12 is su ported horizontally slightly below and in rent of the feeding wheel 4, by a curved bracket 13 which-is pivoted to the bolt 6 and has a lug 14, as shown in Figs. 4 and 6, through which two thumb'screw's 15 project. The thumb screws bear a ainst the ed e of one of the bars 7 and .a 0rd means t or. adjusting the guide finger 12 forward and back, and for varying its elevation with respect to the wheel 4.

For example, by loosening the upper thumb screw'15 and screwing in the lower thumb screw 15, the finger 12 will be retracted and lowered slightly,while"by loosening the upper thumb screw and screwing in the lower thumb screw, the finger 12 will be moved forward and elevated slightly as the bracket 13 pivots on the bolt 6. a

The lates 10 are fastened together by four bolts 16. Each plate 10 has two rivets, the heads of which project beyond the inner face of the plate 10 'to receive reel bars 18,

19. Each reel bar has a slot 20 in its lower end, and an intermediate slot 21 which com municates with a hole 22, the latter being large enough to slip over the head of the upper rivet 17 to permit the reel bar to he slipped down so that the shanks of the rivets 17 engage in slots 20, 21, and thus detachably hold the reel bars in place 'on plates 10. Riveted to the upper end of the reel bar 18 is a spring bar 23 which has a' notch 24 to receive the axle 25 of the reel 26. Two rollers 27 are carried by the spring bar 23 and press against the hub/28 of the reel, their pressure being produced by the inward spring of the spring bar 23, the

upper end of reel bar 18 being tapered as shown to permit inward movement of spring bar 23. the spring bar 23 and bears against the reel ning under its own momentum. The upper thumb screw 29 passes through end of the reel bar 19 is also notched to I' receive the other end of the axle 25 and a handle 30 is provided on the axle to enable the reel to readily lifted out'of its su port. A pair of arms 31 are riveted to e plates 10 and as clearly shown in Fig. 1

extend rearwardly and have notched ends 32 for receiving the axle 25 to support a reel which is not in use.

Two sleeves 33 are arranged in the lower part of the plates 10, the outer ends of the sleeves being'flush with the outer faces of the plates 10. Extending through each sleeve 33 is a supporting tube 34 and each supporting tube 34 is connected detachably with a similar supporting tube 35 by means of an internal sleeve 36, as'clearlyshown in Fig. 7, it being preferred to secure the tube irremovably to the tube 34 and to permit of the tube 35 being slipped off from the end of'sleeve 36 when necessary. In Fig. 5 thetube 35 has been removed. Thetwo sup-' porting tubes 34 are secured to one side'of the deckle frame-3 as shown 'in Figfil by blocks 37, while the two supporting tubes 35 are secured by similar blocks-37 to the other side of the deckle frame." The tubes 34 extend through the sleeves 33. One of the sleeves 33 is grooved in its upper'wall to receive a rack 38 which has a ring 39 atone end encircling the tube 34, and a thumb screw 40 serves to adj ustably secure the rack 38 to the tube 34. J ournaled in the plate 10 is a shaft 41 having a worm 42 which engages rack 38 and a milled thumb piece enables the worm to be easily turned. It is obvious that by loosening the thumb screws 40 that plates 10 and all parts carried thereby may be shifted longitudinally on the supporting tubes 34, 35, in either direction and thereby cause the reinforcing material to be fed to the pulp at the desired point with respect to the width of the sheet of paper to be produced. After the approximate position has been secured by sliding the reel the thumb screw 40 is tightened and then by manipulating the worm 42, a most accurate adjustment of the device can be secured. 1

As shown in Fig. 1 the reinforcement feeder is located over the wire cloth and it is preferred to place it as near the end roll of the wire cloth as is convenient so that the reinforcement will be fed into the pulp immediately after the fresh pulp has been spread on the Wire cloth and while the pulp is in its most liquid condition.

44 designates the reinforcement material, which is wound on the reel 26. By referring to Fig. 8 it will be seen that the feeding wheel 4 is so adjusted that a portion of its rim revolves in the pulp and it is preferred to adjust the finger 12 at a point slightly below the perimeter of the wheel 4. The reinforcing material passes fronr the reel 26, thence between a pair of guide rollers 45 shown in Fig. 1, thence over the wheel 4 which drives the reinforcement into the pulp, the reinforcement strip 44 being caused by the finger 12 to gradually sink, so. that as the reinforcement leaves the finger 12 it lies about in the middle of the pulp. Obviously if it is desired to have the reinforcementlie near the upper face of the paper, the finger 12 should be adjusted at a higher elevation than shown, while if the reinforcement is to occupy a position closer to the other face of the paper, the finger 12 should be adjusted to a lower elevation.

As the sheet of'pulp passes along the reinforcement is drawn into the pulp in a continuous manner, the forward portion of the reinforcement having a sufficiently secure anchorage in the pulp to unreel the reinforcement and draw it into the pulp as the reel turns very freely, and is only retarded suflicientlyto prevent the reel from running faster under its own impetus than the reinforcement is reeled 0-H. Thus the reinforcement after having once been inserted in the pulp is not displaced therein nor does it draw or distort the position of the fibers in the pulp, and during the passage of the reinforcement from the feeding wheel through the remainder of the machine, the fresh pulp becomes thoroughly intermingled with the mesh of the reinforcement and the reinforcement in turn becomes softened by the wet pulp and absorbs the same and thus the reinforcement is perfectly incorporated with the pulp. During the progress of the reinforcement through the pulp on the deckle frame the feeding apparatus being mounted on the deckle frame also partakes of the shaking motion so that the feeding wheel 4 and the rein forcement are always maintained in exact position between the two deckle straps 2 and thus the pulp does not become agitated by the reinforcement as there is no sidewise movement of the reinforcement relatively to the pulp. V

The presence of the reinforcement displaces that slight amount of pulp which is not absorbed by the threads, although a considerable portion is absorbed and the soft threads of the reinforcement become fiattened'out during their progress through the press rolls is, drying cylinders, and calenders and do not produce any bulging of the paper after it is finished.

The pulp with the reinforcement incorporated therein after passing from the deckle frame travels through the first press rolls is, second press rolls L, drying cylinders M and calenders O the remainder of the machine shown in Fig. 11, and the paper is finished in the well known manner.

Fig. 3 shows the reinforcement introducing device constructed substantially the full width of the deckle frame. In this form all of the parts are as previously described except that those parts which extend laterally are made of greater length to span the width of the deckle frame and to accommodate the wide sheet of reinforcement. The width of the device is a trifle less than the space between the side bars 3 of the deckle frame which permits the device to be adjusted the necessary amount on tubes 34 and 35. The clamp 39, rack 38 and worm 42 are located atone end of the device near one of the sides of the deckle frame as clearly shown. This width of device is used when the reinforcing fabric is to extend through the entire width of the sheet of paper.
