UNITED STATES HARRY VAN. ORNUM, OF PIERCEFIELD, NEW YORK.

PAPER-MAKING MACHINE.

Specification of Letters Patent.

Patented June 8, 1920.

Application'filed April 10. 1919. Serial No. 289,102.

To all whom it may concern:

Be it known that I, HARRY G. VAN

ORNUM, a citizen of the United States, re-' siding at Piercefield, in the county of St. Lawrence, State of New York, have invented certain new and useful Improvements in Paper-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the-invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to new and useful improvements in Fourdrlnier machines of the type embodied in Patent No. 1,261,194, granted to me April 2, 1918, and embodying means whereby upon ad ustment of the slice bar longitudinally of the machine, a vertical adjustment is automatically also effected to an extent dependent upon the extent of longitudinal adjustment.

It is in general the object of this invention to improve the structure and increase the operative efficiency of the machine embodied in my said previous patent.

A more detailed and important object, with respect to the slice mechanism, resides in the provision of an arrangement whereln the ratio of horizontal adjustment to dependent vertical adjustment may be varied to adapt the machine for different types of papers.

With the above and other objects and advantages in view, the invention resides more particularly in the novel formation and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevational view of the head portion of my improved paper making machine.

Fig. 2 is a perspective view thereof.

Fig. 3 is a transverse sectional view on the line 33 of Fig. 1.

Fig. 4 is a transverse sectional View on the line 4-4 of Fig. 1.

Fig. 5 is a sectional view on the line 5-.5

of Fig. 3.

Fig. 6 is a section through one of the bar adjusting blocks, and certain of the parts adjacent thereto, on line 66 of Fig. 2.

Referring now more particularly to the drawings, 1 designates the frame of a Fourdrinier paper making machine on which is mounted a Fourdrinier wire 3 trained about combination,

a breast roll 4 at the forward end of the machine, the usual stock conveying apron 5 extending from the apron board 6, hinged to the head box Z at A, with its rear end extending over the Fourdrinier wire and terminating substantially above the center of the breast roll 4. The usual sides 7 of the adjustable deckle frame extend longitudinally over the Fourdrinier wire, having the wheels 8 journaled at their forward ends about and which are trained the deckle straps 9. As in my already issued Patent 1N0. 1,261,194, hereinbefore referred to, a slice is provided which consists of adjustably connected sections 10. In the present instance, these sections 10 consist of thin metallic plates, having their upper edges turned outwardly in opposite directions as indicated at 10, suitable clampsE being arranged for operation to hold the plates at different points of their adjustment with respect to each other. These clamps E are engaged with the portions 10 of the plates 10.

Secured to the outer end of each of the plates 10 there is an angular arm F, the angular portions F of which are directed downwardly outwardly of the sides 7 of the deckle frame.

Feed screws 14 are carried longitudinally by the outer faces of the sides of the deckle frame, and engaged with these screws for movement longitudinally thereof when the screws are revolved, are the adjusting blocks 13 having bosses-15 which extend into and are movable longitudinally of the longitudinal slots 16 formed in the sides 7 of the deckle frame.

Inwardly of the sides of the deckle frame, there are cleats G which are secured in pairs to the bosses 15, these cleats extending vertically, and lying one at each side of one of the plates 10 so that the cleats form vertical guides in which the plates may move, and, engaging the sides of the plate, will move the latter as the blocks 13 are moved.

Connected with the cleats G which lie in the direction of the breast roll 4, there are deckle wings H which extend toward the breast roll and engage the inner faces of the sides 7 of the deckle frame these wings H being thus movable with the blocks 13, longitudinally of the machine.

Deckle wings I, corresponding to the usual transversely adjustable deckle wings employed in machines of this type, overlap the cated at K.

wings H inwardly thereof, as best shown in Fig. 4, and, as illustrated in Fig. 2, the wings I are adjustable transversely of the machine to correspond to transverse adjustment of the sides of the deckle frame, the provision for this adjustment of the wings I being indi- The rear ends of the feed screws 14 are journaled in bearings 14 and carry beveled gears 14: meshing with beveled gears 17 and 18 carried on a shaft 19 passed through and journaled in the deckle frame, one end of this shaft being provided with a crank handle 20, the shaft adjacent said end being provided with a longitudinal keyway 21 in which is engaged a feather 22 carried by the adjacent gear wheel 18, whereby the gear wheel 18 is splined on the shaft, the adjacent end portion of the shaft being slidable with respect to the deckle frame in which it is journaled whereby the drive connection described does not interfere with adjustment of the deckle frame. Thus in any adjusted position of the frame, both feed screws may be simultaneously rotated to adjust the slice.

Each side 7 of the deckle frame has outturned flanges 23 and 23 respectively at its upper and lower edges. To procure, as in my said former patent, an adjustment of the slice vertically, andautomatically contigent upon horizontal adjustment thereof, screws 24 are passed vertically through and threaded in the arms F, and are passed through longitudinal slots 25 in the deckle frame flanges 23. The lower ends of these screws slidably rest upon bars 26 each disposed longitudinally with respect to the corresponding side of the deckle frame, each has its forward end pivoted to the deckle frame, and its rear end resting on a block 27 slidably mounted in a longitudinal trackway 28 on the deckle frame and adjustable longitudinally by means of a feed screw 29 threaded therein and swiveled in a bracket 30 on the deckle frame. a.

By the construction shown and described,

the slice is adjustable vertically and longitudinally of the deckle frame, by a unitary action, as in my already issued patent hereinbefore referred to, and through the medium of the blocks 27 upon which the pivoted bars 26 rest, it is possible to vary the relative degrees, of vertical and lon itudinal adjustment of the slice. It will ofcourse be understood that vertical adjustment of the slice independently of its longitudinal adj ustment may be effected by operation of the adjusting screws 24.

Since the wings I overlap the wings H,

these wings co-act to form continuous bar-.

riers at the sides of the machine, in continuation of the frame sides 7.

What is claimed is:

1. In a paper making machine, the combi nation with the deckle frame thereof, of a slice adjustable vertically and horizontally with respect to the deckle frame, means for effecting the adjustment by a unitary action, and means for varying the relative degrees of the adjustments.

2. In a paper making machine, the combination with the deckle frame thereof, of a slice adjustable vertically and horizontally with relation to the deckle frame, means for accomplishing the vertical adjustment as a result of the horizontal, adjustment, and means for varying the relative degrees of these adjustments.

3. In a paper making machine, the combiment as a result of the other, and means for varying the relative degreesof the adjustments.

5 Ina paper making machine, the combination with the deckle frame and apron thereof, of a slice simultaneously adjustable away from the apron and toward the bottom of the frame, means for accomplishing the vertical adjustment as a result ofthe horizontal adjustment, and means for varying the relative degrees of the adjustments.

6. In a paper making machine, the combination with the deckle frame thereof, of a slice, blocks longitudinally slidable in the sides of the deckle frame, vertical guides slidably carrying the slice, means for moving the blocks, and means for changing the vertical position of the slice as the blocks HARRY e.
