My invention relates to paper making machines, particularly of the Fourdrinier type. One of the objects of the invention is to provide a simple, practical and advantageous machine of the class specilied.

Another object of the invention is-to provide a' Fourdrinier machine wherein the table may be bodily moved or removed laterally to permit application of a new wire,

and may also be shaken to im rove the fibre and may also have its feed en ad'usted vertically to control the character o the fibre.

' Another object "of the invention is to arrange for the proper and cooperative opera` tion of the table, shaking mechanism and pulp holding and feeding devices in carrying out the foregoing operations.

Other objects of the invention will appear and be pointed out hereinafter.

Referring tothe drawings, I show a Fourdrinier machine having a main table portion 1 supporting rolls 2 for the wire 3. An ad- 'ditional or supplemental end portion 1 is 70 also embodied in the machine shown, the same supporting vacuum boxes 5-5 and 6-6and havlng a Jointed connection, as by pivot 7, with the main portion 1, and also having rolls 8-8 and 9--9 for the wire. 75

The table comprising the sections or portions 1 and 1a is adapted for bodily removal in a sidewise manner, to permit the advantageous application of a new wire after a used one has been removed. To such' end 80 provision is made for moving the table out and back sidewise on tracks 11, 12 and 13, the table being shown in normal position in Fig. 2, and moved out on said tracks in` Fig. 3. The table is provided with suitable power mechanism for moving itout and back on said tracks, as for example, an electric motor 15 (Figs. 1 and 5), power connected by spur wheel 16, gear 17, worm 18 and wheel 19 with driving shaft 20 carrying wheel 21 for track 90 r 13, said shaft 20 being coupled to shaft 20a carrying wheels 22 and 23 for tracks 11 and 12, respectively. The rear or back side of the table is provided with wheels 25-25 (Figs. 2, 4 and 6), for traveling on the tracks 95 11, 12 and 13, said wheels 25 being preferably constructed, as shown in Fig. 6, with outside portions 25m- 25a for purposes to be described later.

Tracks 11, 12 and 13 are preferabl con- 100 tinuous and of such length as t'oprovide for the table in both out and in positions and are supported by posts or pedestals 26, 27, 28 andmaintaining tracks in vertical position.

Posts or pedestals 28-have top surfaces which are inclined slightly upward to elevate rollers and thereby permit tracks to be removed. Post 29 has a wheel 29a for serving as a stop to limit backward movement of ta-y ble. Posts 27 and 28 are preferably connected together in pairs by cross beams 40.

Thus it will be seen that the entire table may be moved out to permit changing wire f byoperating motor 15, and then moved back byl reversing the motor, front edge of table normally resting with wheels 21, 22 and 23 on tracks 13, 11 and 12, respectively, and rear of table restin with wheels 25 on track surfaces 37 of pe estals 28.

The mechanism for shaking the table disclosed herein is shown more particularly in Figs. 1 toll, inclusive. It includes a series (four are shown, Fig. 1) of upwardly extending reciprocatory or vibratory members y 43-43 mounted on rock shaft 44, which is supported b bearings 45-45 located on the floor, where y shaft 44 is low and vibration is prevented. Upright members 43 are connected with table section 1 by detachable connections permitting table to be shaken as desired, and also rmitting detachment or disconnection of s aking mechanism to allow removal of table in direction away from such mechanism for applying new wire.

The connections between the two middle members 43 and table are shown in Figs. 2 and 1.5. They comprise straps 51 connected to yokes 52 which are on opposite sides of uprights 43, yoke members 52a sliding between rolls 53-53 on boxes 54 which enclose uprights 43 and are also connected with straps Boxes 54 arev provided with openable sides 55 normally held in position so as to engage upright 43 by bolt 56 and hand nut By unscrewing latter, side 55 may be swung about pivot bolt 58 so as to open box 54 and allow separation of same from upright 43. The connection for the right hand end member 43 is shown inFigs. .17 and 18. It comprises a strap 51 such as previously described, but same has a pivotal connection 59 with the jointed section 1* of the table, and' also a connection 60 with the shaking section l'of the table, whereby both sections are shaken. The connection for the left hind'- most member 43 is shown in Figs. 3 and 4. It

,comprises a box 61, open at one side and having an inclined side and a connection 63 for the brest roll bearing 64. Section 1 of table is mounted on flexible members 41 whose lower ends are secured to channel members 42, to permit shaking of rolls 2 and wire thereon without shaking the remainder of the table.

Vibratory members 43 are actuated by rocking of shaft 44 by vertically vibrating arms 47 actuated by reciprocating members 47 a controlled by shaft 47 b which is turned by gear connection with power shaft 48., so that rotation of latter will vibrate members 43 and so shake table.

Thus the whole table section 1 and brest roll also may be shaken as desired and also detached from shaking mechanism to permit removal of table for applying new wire, as shown in Figs. 2 and 3. A

Inasmuch as table is preferably shaken by shaking mechanism, table sections 1 and 1 are preferably mounted at upper ends of flexible members 41-41 whose lower ends are connected to and supported by side channel members 42-42, below which the various track wheels 21, 22, etc. are mounted, whereby table member 1 may be shaken relatively to members 42-42. The shaking mechanism shown herein comprises a vibratory member 43 mounted on ahrock shaft 44 operated by vibratory member 47 actuated by driving members 48 and 49. Inasmuch as said shaking mechanism is shown, described and claimed in another application of mine, executed of even date herewith, Serial No. 648,962, filed July 2, 1923, Shaking mechanism for Fourdrinier machines, it will not be further described nor claimed herein.4

In accordance with present invention, the feed end of the table and the pulp holding and feeding devices may be adjusted vertically and in such relation as to cooperate properly 1n their various adjustments. This adjustment may be secured by means of suitable elevating devices and connections for accomplishing the desired purposes. As an advantageous arrangement I have shown an electric motor 65 mounted on the top member 66 forming with posts 67 a framework on which the pulp holding and feeding devices are mounted. Motor 65 is geared to power shaft 68 so as to drive same and shaft 68 is connected by sprocket chain 69 with su plemental power shaft 70. The power shafts 68 and 70 raise and lower the feed end of the table 1 and feed box 71 through suitable mechanism referably controlling same, so that they s all rise and fall together in proper relationship, and also so that the feed on end posts 67 and slide disclosed and. claimedbroadly in my Yokes 73 are connected with hangers 76 which engagefthe ends of projecting members 77 on a cross beam 78 which extends under,

neath and vengages feed box frame .pieces 7 9--7 9, so that raising and lowering of yokes 73 will elevate and lowerfeed box 71.

Yokes-74 are connected-with hangers 80 whose lower ends engage projections 81 on the feed end of table section 1, whereby raising and lowering of okes 74'will raise and lower feed end of ta le, whereby it will be seen feed box 71 and feed end of table will rise and fall together. j j As a matter of further and specific improvement, provision is made for tilting feed ,box 71 so that it will incline down toward the table as itand the table rise. For this purpose I show guideways 83-83 and 84-.84 ins or rollers 85 and 86, the former on side rames 87 on feed box 71, and the latter on frames 88 on hangers 88a extending down below feed box 71, being preferably formed integral with frames 79. Guideways 83 are preferably inclined in wardly and upwardly, and guideways 84 outwardl and u wardly, as shown in Fig. 7, whereby feed ox 71 will in effect be t1lted substantially about the feed end of table as bot-h rise and fall, thus insuring proper feed of pulp and proper cooperation of devices in the upward and downward adjustment. Guideways 83 may be adjusted by screw bolts 83'l and guideways 84 b screw bolts 84.

The brest roll on table is preferably made adjustable lengthwise of the table to facilitate applyin a new wire and for other purposes. In t Ae arrangement shown, said roll is mounted on slides arranged to slide in guideways 92 and provided with a rack 93 meshing with a pinion 94von shaft 95 also carrying gear 96 meshing with pinion 97 turned by handle 98, whereby rotation of handle 98 will adjust brest wheel 90 lengthwise of the table.
