Original No. 1,595,593, dated August 10, 1926, Serial No. 692,644, filed February 14, 1924. Application for reissue filed July 11, 1927. Serial No. 205,006.

This'invention relates to the Fourdrinier end of a paper making machine wherein the usual heavy metal frame supporting the table rails, table rolls, deckle mechanisms and the breast roll is omitted thereb providing which may be termed a frame ess type of Fourdrinier section having resilient wooden spring members on which the table rails and the breast roll are mounted independentl of each other above a base which may be xed or adjustable as desired.

It is an object of this invention to provide a Fourdrinier. section of a paper making machine, said section having the various mechanisms to be shaken supportedon wooden spring members affording a construction of reduced weight and cost, and one in which the Fourdrinier wire may be readily changed without excessive loss of time or excessive cost of labor.

It is also an object of the invention to provide a Fourdrinier section wherein the table roll rails and the breast roll are independently supported on different members and are adapted to be shaken either simultaneously or independently.

It is a further object of the invention to provide a-Fourdrinier section wherein the breast roll and the table roll rails are supported on separate light weight resilient members and in which the breast roll, the table rolls and the deckle supports are adapted to be easily removed to permitthe Fourdrinier wire to be readily changed.

It is furthermore an object of the invention to provide a Fourdrinier section wherein the breast roll and'table rails are independently connected to a shaker mechanism so that the breast roll connections with the shaker mech- 40 anism may be removed if desired and a shak imparted to the table rails only.

It is an important object of this invention to provide a paper making machine with a Fourdrinier section of a frameless type and wherein the mechanisms to be shaken are supported only by resilient members mounted on a supporting base which may be fixed or pivoted and provided with means for adjusting the same. 7

Other and further important objects of this invention will be apparent from the disclosures in the drawings and specifications.

Figure 4 is anenlarged transverse section taken on line 44 of Figure 3 with parts p nitted and with parts illustrated in elevaion.

Figure 5 is a fragmeiitary enlarged detail section taken on line 5-5 of Figure 2 with parts omitted.

Figure 6 is a modification illustrating a fragmentary rear elevation of the flow box end of a Fourdrinier section mounted on a fixed base.

As shown on the drawings:

The reference numeral 1 indicates base I-beams which form a base section for the Fourdrinier end of a paper making machine. Upright members 2 are mounted at one end of the beams 1 and are pivoted at 2" on fixed supports 2 to permit the opposite'end of said base beams to be adjusted by screw-jacks 54 or any other suitable raising and lowering mechanisms desired. Mounted upon one end of the base section is a head or flow box 3 provided with an apron board 4. Secured to the sides of the flow box 3 are bracket plates 5 to which are removably bolted or otherwise secured the ends of wooden strips or springs 6. The wooden springs 6 are also removably bolted to breast roll supporting brackets Z on which the breast roll bearings 8 are supported. The'brackets 7 are also supported by pairs of upright wooden strlps or springs 9 the lower ends of which are removably secured by bolts to metal brackets 10 fastened to the base members 1. Journalled in the bearings 8 are the journals of a breast roll 11'.

Formed on the front breast roll supporting bracket 7 is a side bracket 12 to which a U-shaped arm 13 is bolted. Removably connected to opposite sides of the front breast roll bearing 8 are the inner endsof a pair of wooden strips or springs 14 the outer ends of which are removably connected to projecting lugs or arms '16 formed on opposite sides of a yoke 17 which is slidably engaged on a shaker arm or lever 18. The yoke 17 is held in osition on the shaker lever 18 by means 0 the yoke arms 13. A handle nut 19 and bolt 20 are provided to permit the yoke 17 to be removed from the lever 18. The arms 13 slidably project between the projecting lugs 16 and ins or projections 15 formed on the sides of the yoke 17. The breast roll shaker lever 18 is provided with a split bearing 21 at its lower end which is clamped onto a shaker shaft 22 positioned longitudinally along the rear side of the machine.

Secured to the floor in rear of the shaker shaft 22 are a plurality of spaced pedestals or supports 23 each having secured to the top thereof a wooden strip or spring 24. An upright wooden strip or spring 25 is also secured to each pedestal 23. The springs 24 and 25 are removably secured to the split bearings 26 of a plurality of shaker arms or levers 27 which are secured on the shaker shaft 22 and support the same in position with the aid of the springs 24 and 25. The springs 24 and 25 on the pedestal nearest the flow box end are removably secured to the lever bearings 21. The mounting for the shaker shaft 22 isclaimed in my copending application, Serial Number 5,696, filed January 30, 1925, which in so far as its subject matter is disclosed herein is a division of the present application.

Movablv engaged on eaeh'of the shaker levers 27 is a yoke 28. Bolts 29 and handle nuts 30 are provided to permit the yokes 28 to be removed from the levers 27. Guide pins or projections 31 are formed on the sides of each yoke 28. Engaged on the shaker shaft 22 is a lever or arm 32 the outer end of which is connected to a link 33. The link 33 is eccentrically connected to a disk rotated by the shaft 35. The shaft is operated by means of gears 36 driven by a motor37.

Secured at intervals upon each base beam 1 are upright supports or pedestals 38 on the tops of which are secured extension arms 39. The arms 39 on the rear side of the machine are provided with openings 40 (Figure 5). Deekle bars 41 are supported upon the tops of the arms 39 on each side of the machine and support the deckle rails 42. Deckle straps 43 are trained around deckle pulleys 44 and are supported at intervals by suitable wheels or pulleys 45.

Also mounted upon each pedestal 38 to the inside of the arm 39 are upright wooden springs 46. Bolted to the tops of the springs 46 are the table roll rails 47. Mounted on the rails 47 are a plurality of table roll bearings 48 each of which is provided with an adjusting mechanism 49. Table rolls 50 are supported in the bearings 48 beneath the deckle straps 43. The Fourdrinier wire has been omitted for the sake of clearness.

Secured to the rear table roll rail are a lurality of forked guide members 51 the orked ends of which slidably project between the guide pins 31 on the sides of the yokes 28 and support said okes on the levers 27. Removably connectec to the inner ends of the guide members 51 are the inner ends of wooden. shaker strips or springs 52. The outer ends of the shaker springs 52'ar'e removably connected to the okes 28. Wooden springs 53 are supporte on the front arms 39 with the upper ends of said springs 53 supporting the outer end portions of the guide members 51.

Figure 6 is a fragmentary rear side elevation of a modified form of one end of a Fourdrinier sect-ion wherein the parts are supported upon a fixed base 55 instead of on a pivoted base as illustrated in Figure 2.

The operation is as follows: i

It will be noted that a Fourdrinier section of a paper making machine has been illustrated and described in which the ordinary expensive and cumbersome supporting frame for the breast roll and table rails is omitted and replaced by spring supports thereby affording a substantially frameless type of Fourdrinier section.

The shaker mechanisms are operated from the motor 37 which rotates the meshing gzea rs 36,-the shaft 35 and the disk 34. Rotation oi the disk 34 actuates the eccentric link 33 thereby causing the lever 32 to swing upwardly and downwardly to reciprocate the shaker shaft 22. The shaker arms 18 and 27 are thereby rocked toward and away from the table rails and by means of the members 52 cause shaking of the table rails 47 and the table rolls supported thereon. The shaker arm 18 actuates the members 14 thereby causing a shaking motion to be imparted to the breast roll and the Fourdrinier' wire. The upright wooden spring members 9 and the spring members 6 resiliently support the p breast roll and permit the shaking motion to be transmitted thereto. If desired the connecting members 14 may be removed so that a shake will. not be transmitted to the breast roll but only to the table rails.

The spring n' embers 24 and 25 connect ed to the pedestals 23 serve as resilient supports for the shaker shaft 22. As illustrated in (he drawings the resilient wooden spring members 46 support the table rails and permit the same to be shaken by the shaker apparatus hereinbefore described. j

The deckle mechanisms are supported u pm the deckle bars 41 and are not subjected to the shaking action. The deckle rails may be readlllf) l'il - which the breast roll, the table rolls and the deckle supports are adapted to be readily removed thereby permitting the 1*ourdrinier wire to be rapidly replaced when necessary. The spring supporting members are so arranged that access may be readily had to all parts of the Fourdrinier section which was not possible in the old heavy frame type of Fourdrinier constructions.

The base members may be adjusted by means of the screw-jacks 54 about the pivot members 2" to give the necessary pitch to the wire of the Fourdrinier section.

While the supports 6, 9, 24, 25, 46 and 53 are described as wooden members it will of course be understood that they may be made of any other desired materials.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and'I therefore do not purposelimiting the patent granted, otherwise than necessitated by the prior art.

Certain of the subject matter of this application is disclosed and broadly claimed in copending applications of mine, Serial No. 595,- 258 filed October 18, 1902; No. 648.959. No. 648,960, No. 648,961 and No. 948,962 filed July 2, 1923, respectively and hence is not so claimed in this application.
