Patented June 6, 1933 PATENT OFFICE JACOB EDGE, or DOWNING OWN, rJJ NsYLvANrA, AssIGNOR r DOWNINGTOWN MANUFACTURING COMPANY, OF DOWNINGTOWN, PENNSYLVANIA, A CORPORATION OF PENNSYLVA IA A A rnnss CONSTRUCTION FOR PAPER. MACHINES Application filed July 18,1932. Serial No. 623,272. I

This invention relates to presses for paper machinery, and more particularly to a press construction of such character that the bottom press roll thereof ismade readily in dependently removable from the press. I I

r In the ordinary press construction, in order to remove the bottom press roll, itis essential either that the upper press roll be first removed or a carriage mechanism employed which will enable the lower press roll to be shifted in the general direction ofits axis to a point where it is accessible to a sling. Obviously, either of theseimethods is time consuming and requires the services of a number of workmen in accomplishing the remov al; the time elementinvolving a corresponding loss ofproductionby themachine. A An important object of this invention is the provisionof, anarrangement such that two mechanics, one working at each end of the press, can accomplish all preliminary work in positioning the roll where it is readily accessible for removal by the sling.

1 A further and morespecific object Of the invention is the provision ofan arrangement such that the lowerpr'essrollmay be moved bodily longitudinally of the machine bed. when so desiredwith comparatively slight exertion on the part of the attendants.

These and other objects I accomplish by the construction shownin the accompanying drawing wherein, for the purpose of illustration, I have shown a preferred embodiment of my invention and wherein: s Figure 1 is a side ,elevationof a main press embodying a lower roll mounting constructed in accordance with my invention; Fig. 2' is an enlarged side elevation of bearingbase; i J Fig. 3 is a transverse sectional view therethrough; and

Fig. 4 isa showing the stops for controlling the posi- Referring now more particularly to the drawing, the numeral generally desig-- nates a frame having arising therefrom a standard 11-mounting,'through a lever 12, the usual upper press roll18. This upper press roll 13 verlies alower press roll 14 fragmentary sectional view andrin the ordinaryconstruction prevents removal of this lower press roll until the upper press roll has been removed. At the opposite sideof the press roll 14 from the standard 11, standards 15 are employed for supporting a cross-walk 16,this cross-walk being ordinarily disposed in fixed position with relation to the standards 15 which support the same. r

In accordance with my invention, I provide bases 17 for the bearings 18 of the lower press roll 14, these bases being seated upon ongitudinally-extending, longitudinally fiat ledges 19 forming a portion of the upper surface of the frame member 10. Each bearing baseis in the form of a hollow, preferably open, bottom frame having closed ends 20 formed with cars 21 for the passage of location pins 22 whereby the bearing base may be disposed in proper position upon the frame during operation of the machine.

Each bearing basemounts a pair of shafts 23having eccentrically formed portions 24 disposed interiorly of the hollow base. Upon these eccentric portions are mounted rollers 25.. The outer end of each shaft is squared, or otherwise adapted, as at 26, for the reception of a wrench Or tool whereby it may be rotated to move the rollers into and lie the cross-walk 16. The crosswalk is, ac-

cordingly, mounted upon arms 28, and these arms 28are pivoted at 29 upon the upper ends at of the standards 15 so that the cross-walks may be vertically positioned as indicated in dotted lines, leaving a clear passage for the sling and the press roll 14 when supported thereby.

.In orderthat the rollers may be securely positioned-when functioning to support the ter of rotation. means, as more clearly shown 1n Fig. 4, compress roll, means are provided for limiting rotation of the eccentrics 24 shortly after these eccentrics have passed the bottom cen- In the present instance these prise stop pins 30 mounted in such eccentric portions and coacting with stop lugs 31 formed on the base 17 Since the construction employed is, obviously, capable of considerable modification without in any manner departing from the spirit of my invention, I do not wish to be understood as limiting myself thereto except as hereinafter claimed.

I claim:

1. In a press for paper-making machines, spaced frame members, roll supporting elements mounted thereon, anti-friction members permanently associated with one of the frame members and supporting element at each side of the press, and means to interpose the anti-friction means between the frame member and roll supporting element.

2. In a press, a frame supporting upper and lower press rolls, said frame comprising means for guiding and supporting the lower press roll during movement thereof longi tudinally of the press from a position where it underlies the upper press roll to a position where it vertically clears the upper press roll.

3. In a press, spaced frame elements, a lower roll. supported therefrom, standards arising from said frame elements at corresponding ends thereof, an upper press roll carried by.

4. In a press, spaced frame elements, alower roll supported therefrom, standards arising from said frame element-s at corresponding ends thereof, an upper press roll carried by the standards and overlying the lower press roll, said frame elements including longitudinally-extending supporting surfaces along which the lower press roll may be moved to a position where it vertically clears the upper roll, a cross-walk, and means at the opposite ends of the frame elements supporting the cross-walk for movement from a position where it overlies the lower press roll when cleared of the upper press roll to a position where it vertically clears the lower press roll when in such position.
