Patented June a; 1909.
Application filed July 16, 1908. Serial No. 443,777.
T 0 all whom it may concrn: I
Be it known that 1,- I ENRY J. citizen of the United States, resid ford, in the county of Essex and Commonwealth of. llfltlSSfifillUSOttS, have invented new and useful Improvements in Paper-Ma chines, of which the following is a specification.
My invention relates to improvements in paper machines and more particular] it) the type of paper machines'known as cylinder machines wherein the paper stock is made to adhere to a wire mesh upona cylinder immersed in a vat containing the stock and my improvement consists in providing the cylinder with an endless wire mesh which travels around and upon the cylinder and is carried over a series of drying rolls to couch rolls spaced apart a long distance from the cylinder.
It further relates to certain details of construction to be hereinafter more wirticulurly setforth and claimed.
In the drawings herewith accompanying and making a part ofthis application, Figure 1 is a side elevation partly in section of as much of a pa or machine as is necessary to show the app 'ication of my invention thereto; Fig. 2 1s a transverse vertical section of Fig. 1 taken one line passing-through the cylinder shaft; Fig. 3 is a plan of the guide ring, and Fig. 4 is a detail elevation of one of the component parts of the cylinder;
Same characters of reference refer to like Mnnnnma 1 In said drawings A is a vat for containing the stock and B is a cylinder mounted in said for admission of the stock thereintoand it is also provided with a false bottom 3 which causes the stock entering through port 2 to pass down into'the bottom of the vat under the' cylinder and below thefalsc bottom takin Fig; 1,: whereby the stock is caused to become thoroughly commingled in the vat and through all parts where it comes in contact mesh thus producing a moreeven agamst an part of1the mesh. The cylinder er rings mg at Braded wit-h a suction pump assimilated and homogeneous before and consequently to adhere from the mesh.
construction and inounted'wholly within the vat which prevents it from becoming injured b any means outside the vat and also keep it free from dirt or any matter liable to injure the cylinderor aper stock and this arrangement of the dechle is found to be exceedingly advantageous. Between the cylinder and the. end of the wall of the vat is a guide ring J having a suitable packing K. Outside of the vat is a water reservoir L and leading from the cylinder thereto is a. port M and leading from the water reservoir is a pipe N connectnot shown which. may be of any convenient construction.
The cylinder may be driven either by the mesh or in any convenient way.
The operation of my improved device is as follows. The vat in which the cylinder is mounted is supplied with a continuous supply of paper stock through port 2 which by reason of the false bottom becomes perfectly it is presented to the mesh and is by reason thereof presented to the mesh in a uniform manner.
The suction pump tends constantly to pro duce a vacuum. in. the cylinder thus causing the stock to tend to penetrate the cylinder uniformly to the endless wire mesh. The wire' mesh leaves the cylinder at the point 0 taking with it the paper stockwhich is adhering thereto whence it is carried over the drying rolls where a large portion of the water is extracted, and thence on to the couch rolls where it is taken its advantages'are that it is siinple, in construction, presents the paper stock unifor -nly to the wire mesh and retains.
it upon :the mesh until it has become firml r compacted together after becoming dried to a considerable degreeonthe-mesh and before it reaches the couch roll, the couch roll being s aced apart a considerable distance from t1 e cylinder instead of being adjacent'tothe cylinder as In the-'cyhnder-machine's as at present constructed where the couch rolls vtake the paper sheet'from the cylinder before any of the water is extracted therefrom; Another advantage 153 that the declde is entirely concealed within the vat and not exing a false bottom, a rotatable cylinder mounted therein above said false bottom, a
' port, leading into the vat below said false bot- 10' tiam, an endless wire mesh adapted to travel around said cylinder and memos for imparting motion to'said mesh. I
2. In acylinder paper machine, a rotatable cylinder, an endless wire mesh adapted to travel around said cylinder, couch rolls and drying roll's intermediate said cylinder and said couch rolls, and means for imparting motion to said wire mesh.
3. In a cylinder paper machine, a vat, a
rotatable cylinder mounted therein, an end- 20 less wire mesh adapted to travel around said cylinder and a declde mounted wholly within said vat.
In testimony whereof, I have signed my name to this specification in presence of two 25 subscribing witnesses this sixth day of June, 1908.
