APPARATUS FOR THE MANUFACTURE OF PAPER.

SPECIFICATION forming part of Letters Patent No. 338,364, dated March 23, 1886.

Application filed J anuars 12, 1886. Serial No. 188,345.

To aZZ whom, it may concern.-

Be it known that 1, CHARLES JOHN Bron- ARDSON, a subject of the Queen of Great Britain, a resident of Team Valley Paper Mills, Gateshead 0n-Tyne, England, paper-manufacturer, have invented certain new and useful Improvements in Apparatus for the Mannfacture of Paper, of which the following is a specification.

The object of the invention is to afford increased facility for effecting changes in the width of paper during manufacture without necessarily stopping the paper-making machine.

As paper-machines are now generally arranged the deckle-frames which regulate by their position the width of the paper, are pushed in or drawn out by hand when an alteration in the Width of the paper is required, and the apron or lip which is attached to them has also to be rolled up or spread out, as the case may be, by hand. This operation can only be carried out well when the paper-machine is at rest, thus involving loss of time and material by a stoppage. The two deckle-fr'ames can also only be dealt with one after the other unless a double staff of men be used.

According to my invention the deckleframes are made to move in or out simultaneously under the manipulation of a single man without any stoppage of the paper-male.

ing machine, while the action of the same mechanical means rolls up or spreads out the apron in the required manner. The deckleframes are carried by two parallel horizontal bars extending across the machine. These bars are geared together so that they can be turned simultaneously by one hand -wheel. By means of right and left hand screw-threads upon them the deckle-frames are moved in and out when the bars are turned. The deckleframes carry the wheels on which the deeklestraps run. They also carry horizontal rollers onwhich the apron is wound as the deckleframes approach, and from which it is unwound as they recede from each other. A cord and weight in connection with each roller keeps the apron always strained. The slices also which regulate the flow of the pulp are connected with the deckle-frames and move (No model.)

in and out with them, sliding the one on the other.

Figure 1 of the annexed drawings is a halfplan of the deekle-frames and other apparatus concerned in the alteration of the width of the paper. Figs. 2 and 3 are sectional elevations of the same. The sections are taken on the lines A B and C D in Fig. 1, respectively.

a a are two round bars supported in bearings b Z) on the side frame, 0, of the paper-machine. There are screws on the bars a, and the threads of these screws are right-hand on one side of the machine and left-hand on the other.

(i is one of the deckle-frames. There is a similar frame on the other side of the machine.

6 is a hand-wheel, by which the bars a can be simultaneously turned, the bars being geared together by means'of chain-wheels and an endless chain, f. Hence, when the handwheel is turned, the deckle-frames (with the parts which they carry) approach to or recede from each other. The plate (1 forms a part of the deckle-frame, and it constitutes one side of the trough g, from which the paper pulp is delivered onto the traveling web of the machine.

H is the deckle-wheel. It is carried by an axis on the deckle frame, and the endless deckle-strap K runs around it. The width of the paper depends on the position of the decklestraps, and is controlled by them in the usual way.

L is a roll, carried by brackets fixed to the inner side of the plate 01. The ends of the apron M are fixed to the rolls L on either side of the machine. Each roll L, at one end, is provided with a small barrel, N, to which a cord, 0, is attached. It is lapped around the roll and at its farther end it carries a weight, P, tending to wind up the apron on the barrel and keep it tight, but, nevertheless,a1lowing the apron to unwind from the roll L when the deckle plates are moved farther apart. The slices R R, which control the flow of the pulp, are jointed together at the center, so as to admit of their sliding in and out, and they are self-supporting. Their ends are received into guide-grooves Q in the plates d, in which they are adjustable vertically by the thumb screws S.
