C. E. CONLEY SUCTION ROLL sept. 1, 1931.

vFiled Aug. 29, 1929 2 Sheets-Sheet 2 Patented Sept. 1, 1931 PATENT OFFICE CHARLES E. CONLEY, 0F NORWICH, CONNECTICUT, ASSIGNOR TO DOWNINGTOWN MANU- FACT'UB'ING COMPANY, OF DOWNINGTOWN, PENNSYLVANIA, A CORPORATION 0F PENNSYLVANIA SUCTION ROLL Application ledAugust '29, 1929. Serial No. 389,297.

This invention relates to 'suction rolls for paper machines. j Y

An important obj ect of the invention is the provision of`a simple and effective means for maintaining the suction box of ,such rolls in any desired position within the roll.

I A further object of the invention is to provide a means for readily adjusting the box which serves to lock the box in its adjusted positions in the roll.

A still further object ofthe invention is to provide in a structure of this character an arrangement such that the position of the box within the shell may be determined at any time.

A still further and more specific object of the invention is the provision of a construction enabling the heavy side of the suction box to be turned to the bottom so that the box will' be supported and balanced during dismantling operations.A

These and other lobjects I attain by the con struction shown in the accompanying drawings wherein, for thepurposeo'f illustration, I have shown a preferred embodiment of my invention and wherein: l

lFig. 1 is a longitudinal sectional view through a suction roll equipped with suction box adjusting means constructed in accordance with my invention; Fig. 2 is a side elevation thereof; and

Fig. S-is a section on line 3 3 of Fig. l,

portions of the end head of thel shelllbeing broken away to illustrate the position ofthe paekings of the suction box with relation to the indicator.

.Referring now more particularly to the drawings, the numeral 10 generally designates the perforated shell of a suctionl roll and 11a head attached to the roll and' having projecting therefrom a hollow journal 12 mounted in a bearing 13" and rotated through a suitable driving means.

Arranged within the shell 10 is a suction box-.14 having a head 15- equipped with a project-ing tubular extension 16 directed through the journal -of the sh-ell. Exteriorly to the journal the outer end ofthe tubular extension 16 is equipped with an exhaust header 17 which through a quick'detachable iange 21 through a loose block 23 which may be removed to enable the felts or wires of the machine to be changed. To this block I secure a bracket24 affording bearings 25 for a worm 26 which meshes with worm gear 20.

It will be obvious that by rotating worm 26, which is equipped with al wreneh-receivf ing shank 27 to permit rotation, the tubular extension 16 and through this extension the suction box`14 will be rotated to place the suction box in a desired adjusted position. To assist in this adjustment the face of the gear 20 is equipped with indicator marks 28 aligning with the inner faces of the packings of the suction box and by noting the position of these indicator marks a desired adjusted .position of the box may be obtained without the necessity of removing the felts or wires to permit the inspection of the roll. When it is desired to dismantle the roll the box 14 through worm 26 may bel rotated until these .packings are disposed at the lower end of the shell s o that the box will besupported from the shell-walland will not be inclined to suddenly rotate when released.

.While I have disclosed the box adjustment l asvsecured to a tubular extension'whieh communicates with a header, .it will of course, beunderstood that this arrangement can be modified and the adjustment disposed at either endof the roll simply by extending the head journal of the box ',suiciently to enable application of the gear 20 thereto. This arrangement may be applied with equal facility to either a direct or non-direct driven roll and may be placed at either end of the vroll as is found necessary or desirable. It

will be noted that the construction provided allows not only adjustment of the suction box but also provides for complete rotation thereof if desired. Such complete rotation is un necessary, but rotation through at least 180 'should be provided. j

Since the construction is capable of a considerable range of change and modification,

I do not Wish to be understood as limiting myself to the specific arrangement herein disclosed except as hereinafter claimed.

I claim:

1. In a suction roll, a support, a bearing above and in spaced relation to the support, a perforated shell having a tubular journal engaged in said bearing, a suction box Within the shell and having an extension projecting through said journal at the outer end thereof, a removable block supporting said bearing from the support and means supported from said removable block operatively engaging said extension to rotate the same from which the extension is disengageable by a vertical movement.

2. In a suction roll, a support, a bearing above and in spaced relation to the support` a perforated shell having a tubular journal. engaged in said bearing, .a suction boX within the shell and having an extension projecting through said j ournal at the outer end thereof, a removable block supporting said bearing from thevsupport and means supported from said removable block operatively engaging said extension to rotate the same from which the extension is disengageable by a vertical movement, said rotating means having engagementwith said extension locking the same in adjusted positions.

3. In a suction roll, asupport, a bearing above and in spaced relation tothe support, a perforated shell having a tubular journal engaged in said bearing, a suction boX Within the shell and having an extension projecting through said journal at the outer end thereof, a removable block supporting said bearing from the support, a bracket projecting from said block, a horizontal Worm rotatably supported by the bracket and a Worm gear secured to the extension of the suction box and engaged with said worm.
