SPECIFICATION forming partbf' Letters Patent No. 703,714, dated July 1, 1902. Application filed June 22, 1901. Serial No. 65,570. (No model.)

To all whom it may concern: 1

Be it known that 1, CHARLES H. WARNER, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new auduseful Improvements in Paper-Making Machines, of which the following is a specification.

The present invention relates to what is knownin the art as a Fourdrinier machine if and its object is to provide an improved machine of this class. Fourdrinier machines as at present constructed have many objectionable features, among which may be mentioned the multiplicity of their parts,- the inaccessibility of many of those parts, which must be removed and replaced when a new making-wire is to be put on, and the obstruction which the means for'supporting the side rails offers to access to the save'alls. In the development of the Fourdrinier in order to meet new requirements inventors and builders have added parts to such an extent that the present machine of the adjustable type has such a large number of parts that it is not only expensive in its construction, but' by reason of said parts it is unwieldy and; cumbersome and open to the further objection that the disposition of its parts, and especially the parts for supporting the side rails, make the operation of removing and replacing a making-Wire a slow and tedious one. Furthermore, these rail-supports and other parts at the sides of the machine render the save-alls difficult of access, whereas they should be freely accessible.

The object of the present invention is to provide a machine of the class described which is not open to these objections, and

these objects are accomplished by constructing the machine in the manner hereinafter described and as shown in the accompanying drawings, which are made a part of this specification, and in which Figure 1 is a side elevation of a Fourdrinier machine embodying the invention. Fig. 2 is a side elevation of the breast-roll end thereof on a somewhat larger scale. Fig. 3 is an end elevation of the breast-roll end thereof, some of the parts'beingshown'in section. Fig. 4 is a vertical transverse section thereof.

The shake-frame, as this term is used in this specification, comprises the two side rails .A and the breast-roll frame B. The side rails are of sufficient strength and rigidity to support adequately and without any considerable lateral yielding all of the parts that are customarily supported by them, including the table-rolls G and the deckle-pulley and its. associated parts, while said rails themselves are supported only at their ends and without any intermediate supports, such as customarily used. At one end each of the rails is pivotally supported by a bracket A, projecting from a post A and at the other end each of the rails enters between a pair of jaws b b on the side portions B of the breast-roll frame, the rails being held in place between said jaws by bolts a. The tablerolls 0 are located above the rails A and are supported by said rails through the medium of journal-boxes or appliances 0 of any desired construction. The placing of the table-rolls above the rails is open to the double advantage that they are not only more accessible when so placed than they would be if placed below the rails in customary manner, but, in addition to this, placing them above the rails leaves a clear space below the rails, affording access to the save-ails, as hereinafter described.

It is wellunderstood by those skilled in the art thatin order to remove or replace the making-wire all parts within it must be removed, and among these are the save-alls, which I have shown at D as being made of corrugated galvanized iron. I desire to have it understood, however, that the invention is not limitedto or concerned with the construction of the save-ails, but is concerned with the means for supporting them. Heretofore they have been supported by rails which extend from side to side of the machine transversely, the ends of the rails being supported by suitable posts; but instead of this arrangement I support them by means of two rails E and'E, which are longitudinal with respect to the machine, one being located at each side of the machine, said rails being supported by posts F. As shown more clearly in Fig. 4, these rails are inthe form of channel-irons, and the rail E at the discharge sideof the save-alls is lower than the rail Eat the opposite side, with the result that the water falling onto the save-alls will flow off.

The breast-roll frame consists of a heavy beam having a horizontal portion which extends from side to side of the machine and vertical orsubstantially vertical side portions B, which extend upward and carry the boxes G for the breast-roll H.

For supporting the breast-roll frame I use two or more devices I, which are, in fact and in effect, rollers-that is to say, they have at top and bottom curved surfaces 11, struck from the same center and of equal radius, said center being at right angles to the direction in which the shake-frame is vibrated, or substantially so. lVith these rollers the breastroll frame may be vibrated from side to side without any vertical movement whatever, precisely the same asif the deviceslwere continuous rollers upon which the breast-roll frame rests. They are not made continuous, for the reason that their movement is slight; but they are, in fact, portions or segments of rollers, and in operation, their range of movement beinglimited,they perform precisely the same function as rollers. As shown in the drawings, each of them comprises the two curved portions 'i, one, at top, engaging the breast-roll frame and the other, at bottom, engaging a suitable support, end flanges i, and a central web 1', which joins the parts i t". In addition each of the curved portions 6 is provided with a lip or spur i, which enters a recess or depression for the purpose of preventing the accidental displacement or creeping of the roller.

As shown in the drawings, the rollers I are supported by a beam J, which extends from side to side of the machine beneath the breastroll frame and is capable of vertical adjustment, but incapable of horizontal movement either laterally or endwise. The beam J is guided between a pair of standards K at each side of the machine, said standards being cast integrally with a base from which rises a screw L, the lower end of which is non-rotatively mounted in a socket in the base 7t. Each of the screws passes upward through a box formed at the end of the beam, and within this box a worm-wheel M is mounted upon it, so that as the wheel is turned in one direction or the other the beam will be raised or allowed to fall bygravity, according to the direction of movement. For the purpose of simultaneously operating the worm-wheels M in the two boxes at the opposite ends of the beam a shaft N is journaled in the beam and is provided in each of the boxes with a worm O, engaging the corresponding worm-wheel,

one end of the shaft being extended beyond the box and squared, as shown at n, for receivlng a wrench for turning it. The beam is in the form of a channel-iron, and each of the boxes is the result of a web 7, closing the channel-iron at its extremity, and a web j, located some distance from said extremity, the two webs j andj being perforated for the passage of the shaft. The bottom of the box consists of a platej secured in place by bolts or other suitable devices.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine of the class described, the combination with the table-rolls, of a pair of rails supporting them, means pivotally supporting said rails at one end, a breast-roll frame supporting said rails at the other end, said rails being without any intermediate support, save-alls arranged beneath the tablerolls, rails parallel with the rails aforesaid, supporting said save-alls, and posts supporting the rails last aforesaid, substantially as described.

2. In a. machine of the class described, the combination of a shake-frame comprising a pair of rails and the vertically-adjustable breast-roll frame, said rails being supported at one end by said breast-roll frame, means pivotally supporting said rails at the other end, said rails being Without any intermediate support, means for vertically adjusting the breast-roll frame, and table-rolls located above said rails and suitably supported thereby, substantially as described.

3. In a machine of the class described, the combination with the shake-frame, including the breast-roll frame, of a beam crossing the machine from side to side and arranged beneath the breast-roll frame, means interposed between said beam and breastroll frame for supporting the latter and permitting the shake-frame to move from side to side, a pair of vertical screws, worm-wheels on said screws supporting the beam, worms meshing with said worm-wheels, and a shaft extending from side to side of the machine and carrying said worms, substantially as described.

I. In a machine of the class described, the combination with the shake-frame, of the beam J crossing the machine from side to side, means interposed between said beam and the shake-frame for supporting the latter and permitting it to move sidewise, a pair of vertical screws, worm-wheels on said screws, worms meshing with said worm-Wheels, and a shaft carrying said worms, the beam having at its ends boxes in which the worm-wheels and worms are contained, substantially as described.
