. Toall whom it may concern:

Be it knowntliat' 1, JAMES WALsn, a citizen of the United States of America, and a resident of Holy'o'ke, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in' ing to that set forth in Letters Patent of the.

United States granted to me August 30, 1904,

l No. 768,834, the present improvements being applicable in con unction with either a cylinder-machine or aFourdrinier maclnne.-

A special purpose of this invention is to render it easy to produce separate sheets having some or all 0 the edges thereof of a charactor as may be desired, and more especially somewhat irregular and of the common form known as deckle edges.

The invention comprises, in combination with an endless web-carrier wire or a ron,- our drinier machine, a revoluble blade or sever-v which may be the ordinary wire of a ing device, which is mounted for its movements on an axis aboveand transversely of the wire, havin movements. or revolutions at suitable spec and to exert or produce an impingement against the web for separating it at intervals for dividing the latter in its running length into portions of uniform longitudinal dimensions. v I

The invention, furthermore includes, in

means for subjecting the lade to a cleansing action, employing water therefor, whereby v the blade may be relieved of any accumulations of ,pulpor fiber thereon, and means are furthermore included for the reception of the cleansing-water in such a manner that the latter cannot flow or fall'upon the web and its carrier for the impairment of the paper .in

course of manufacture; and .the invention, furthermore, includes, in combinationwith the foregoing, means for longitudinally dividing the web separated transversely by the aforementioned means, so that sheets of so given length and also of widths fractional of that of the original web are produced in the machine while the web is in a still moist condition and before it reaches the couch-rolls and drier. v

The improvements pertaining to the'papermachine are illustrated in the accompanying Specification of Letters Patent: Application flied July 8, 1905-. Serial-No. 268,824-

, Patented Jul 31,1906.

Fig. 2 is a front elevation as viewed transversely of the machine of'the revoluble blade andjtlie catch-receptacle for the cleansing water de-e livered thereupon; Fig. 3 is a cross-sectional view as taken on line 3 3, Fig.2. Fig.4 is a front view as seen transversely of the machine of the means for dividing the full-width web on longitudinal lines. Big. 5 is a""view showing the means for giving an intermittent flow of cleansing-water onto the transverse severing device.

boxes and between the latter and the guiderolls. This blade is mountedon arms I) b,

having rigidl affixed outwardly-extended alined journa s d d, the'common axis of both of which is horizontal and transverse of the plane of movement of the wire, suitable 'ournal-supports f "being provided for the our'- nals d at the sides of the machine-frame, and on one of the journals (1 a pulley g is provided, whereby through a belt to rotate the parts (I in the "ournal-bearings and to impart regular revoluble movements to the blade 0,. The said blade is'so mounted and positioned relatively to the plane/of the upper course of the wire as to give impingement thereagainst once in each revolution and separate the web, the s eed offlmovement of the blade being slight y greater through the driving means (which merely requires therefor common movement of the revoluble blade, this mechanical skill) than the progressive movement of the wire and web, and thereby an absolute division and separation on the transverse line of division of the web is acquired.

it represents a pipe transversely arranged above the wire in proximity to the course of 1 e having a series of nipples or jet-holes a r i rected toward the blade and for distributing water delivered throu h the pipe h for etl'ectually cleansing the bIade of any accumulations of pul or fiber coming thereon by rea- 'son of the dividing or severing action of the blade in relation to the-Wet paper Web.

In the supply-conduit leadin to the ipe h a valve is provided, combined with Which is automatically-operating means for periodically opening and closing the water-discharge through the pipe, so that the spraying or jet delivery on the blade may be intermittent and timed for operative efiiciency and in a manner to avoid water Waste and also liability of improperly flooding the traveling we The valve is shown at k Fig. 5, made hollow and endw'ise open toward the pipe 72. and with a port if to open and shut ofi communication with the water-supply conduit h, and the valve is rotated for the water-delivery action by sprocket wheel and chain connection with one of the journals (1 of the revoluble blade.

is represents a trough for catching the water delivered onto the blade and for preventing its falling onto the wire or the web carried thereby, and, as shown, this trough is hun by its suspension-arms n on studs or inward extensions m from the radial blade-car.- rying arms I) and which are axially coincident with the gudgeons or journals (1.

The waste Water may be discharged or removed from the trough kin any suitable manneras, for instance,'by havin an opening 0 at one end of thetrough-so t at the water may flow out and over the edge of the web.

While the bladeis shown in Figs. 2 and 3 as carried on arms radially extended from and rigid with the journals (1, the same might be supported on a skeleton or open-work cylindrical frame ournaled in the manner shown for the here illustrated supportingarms and Within which skeleton frame the catch pan or trou h is could be suspended.

In advance of t e transverse web-dividing blade and between the same and the couchrolls is mounted a transverse rotatable shaft g, having thereon. one or more dividing disk wheels or slitters t, these having hubs receiving set-screws u for adjustably positioning these longitudinally-dividing disk knives or slitters to accord with the widths of the web desired. The edges of these disk knives may be sharp or blunt, as either character of ed e may be provided thereto to accord with the character of edge desired for the subdivided paper to be produced in the machine. The sheets. after passing along on the Wire and subjected to the novel mechanism described are carried past the couch-rolls between the adjacent aprons H and J to the drier K and finally delivered from the latter in a stack or otherwise. I

Having thus described my invention, What I claim, and desire to secure by Letters Patent, is

1. The improvement in a paper-machine, herein described, consistingin the combination with a wire or web-carrier, of a device for completely severing the web revoluble about an axis transversely of, and adjacent to, the plane of movement of the carrier and having an efiective severing length as great as the width of the wire.

2. In a aper-rnachine, the combination with the wire, and a revoluble web-,severin device, arranged transversely of the wire an as described, of a water-delivery pipe for directing the liquid onto, and for cleansing the web-severing device.

3. The combination with the wire, and a revoluble web-severing device, and a pipe, arranged as described, of a trough arranged transversely above the course of the web, and hung on sup orts coincident with the journal-supports orthe revoluble severing device.

4. The im rovement in a paper-machine, herein descri ed, consisting in the combination with a wire or web-carrier, of a device for completely severing the web, revoluble about an axis transversely of, and adjacent to, the plane of movement of the carrier, having an effective severing len th as great as the width of the wire, and a s aft located beyond the transverse severing device and toward the dry end of the machine, and having one or more disk knives for longitudinally dividing the already cross-severed web-sections.
