To all whom it may concern."

Be it known that I, WILLIAM C. Nws'u, a citizen of the United States, residing at Ne'enah, in the a county of Winnebago and State of \Viseonein, have iuvented'a new and useful Improvement in Paper-Making Machines, of which the fd'lowing is a specifica- My invention relates to an improvement in the Fourdrinier or Harper shaking part of a paper making machine, exclusively, and consists in removmg the shaking movement from .that portion of the paper making machine which supports the dcckle frame, the duckies and slices, at. the end of the machine where the paper stock is delivered from the How box to the JR W1 niachine wire b transl a e.

' fcrring the support of the deckle frame from the two shaking side rails of the machine frame to apart of the frame ofthe machine that is fixed, a part that. cannot be affected vin any manner-by the mechanism which ope'l'aies the shaking movement.

The manner in which this is actomplished shown in the accompanying drawing, in which,.

Figure lis-a side elcvationof that end of a paper making machine to which the shaking movement is applied, some unimportant parts of the mechanism, those that can in no way be affected by thcehangcs in construction which my invention requires, being omitted. Fig. 2 is a transverse section of thcmachiuc upotitlmmltne a, (not Fig. l, as

e i r t appears in looking toward the loft. Fig.

is a plan showing a part. of the fiowl box, the apronboard, the oils, and including the first dccklc frame connectingshaft, with my improved method of supporting it. v

, Similar numerals and letters indicate like parts in the several views. .It'Should be understood that my improvcment as here shown is for application to papcr'making machines already constructed,

they usually requiring special y made parts for transferring the supports for the dcckle :frames from the shaking rails where they have heretofore been supported, to a part of the machine frame which not shaken, and that in the construction of new machines, slight changes can be niadc in the form of the dccklc frame connecting shaft journal boxes as here shown, which will be obvious to a paper mill machinist, that will lessen the cost of the improvement;

machine frame; 2, the pillar at the end of the frame to which the shakingmovement is applied, said pillar having a hinge joint 3, for permitting the upper end of said pillar to oscillate transversely, and a bar 3, above the joint 3 for connecting the pillars 1, indicates the bottom rail, or sill of the upon. opposite sides ofthe frame and causmg the pillars to oscillate together.

:4, is a pillar upon which the upper side rails 5, are pivoted'upon the pivot bolts 6. 7, are intermediate supporting pillars under the rail 5; and S, pillars for supportinga save-all 9 under the nnichinc wire.

10, is a all suspended below the shaking rail 5, and in the present case is shown 5 15 are mounted; 18, the flow box, from which the paper stock is delivered uponthe machine wire; 19, apron board extendng outward from the flow box upon which the stock iscarried b gravity to the Wire;

.20, elbows, or ells, at. aches to the How box andadjustable in pdsitio'n by means of hand wheels 20", foradaptinp, the width of fiow to the width between the dccklcs; 21, a fieXi ble apron extending from the apron board forw ard upon the wire; 22, slices for gaging the thickness of the the paper sheet.

, The shafts 14, which-connect the two side, frames 13, have heretofore been supported in journal boxes at their ends mounted upon stands under them which were secured to.

the shaking rails 55 and consequently, the

decide frames, dcckles and slices, .which were connected directly to the frames and were mounted upon the rails 5,,receiVed the same degree of shake as the wire and the rails 5. I y

For relieving the deckle frames and their attachments from said shaking, the boxes 23 are provided With an arm 24-, which ex tends downward and j then horizontally and-is prqyided with aka-1 piece 25, which is fitmdtqandadjustably secured with a set scrw fifl, upon the upper: end of a pillar 27, which extends upward from the sill 1. The pillar being erected upon the sill of the machine frame is unaffected by the shaking of the side rails 5. In this manner all shake to the deckle frames and slices is avoided, resulting in making a more uniform and smoother sheet of paper, as there is no springing of the slices on the deckle' frames. It will make a stronger sheet, as the fiber upon the upper side of the sheet will be drawn and Woven in a zig zag shape by the slices being stationary and not having the motion of the wire. It will overcome foam specks, as the churning of the stock between the slices .is avoided. No

' lumps will form on the slices or ells on apron, as there is no motion to them to cause it. It will be easier on the machinery and? deckle straps or hands. The paper will run safer, as theedges will be perfect, no tilting of the deckle straps or thin edges in the aper. It will require less power to drive the shaking mechanism.

" At the-left hand in Fig. 2, the cap piece.

25, is shown partly in section, it being made integral with the arm 24: and journal box 23, and bored for fitting around the stem 28 mas drinier or Harper type having the usual shaking rails, shaking Wire, and deckle frames, deckle frame connecting shafts, deekles and slices, arranged above the shale ing wire, a pillar upon a non-shaking part of the machine frame, a stem extending up ward from the upper end thereof, a journal box fitted to and mounted upon a deckle ,t'rame connecting shaft and being provided with a cap piece or part adapted to be mounted upon and lllClOSG a part of the stem of the pillar aforesaid, and a set screw in said cap piece for adjusting the height of said cap piece upon said pillar.
