Application filed February This invention relates to a suction box for paper making machines. The principal objects of the invention are to provide for the manufacture of a suction box of sheets and structural shapes of metal in such a way as to avoid the handling of the large and heavy pieces now used and to make the suction box throughout of material which will not be attacked by the liquids and chemicals used in paper making and will be of a light character so as to be handled easily.
Other objects and advantages of the invention will appear hereinafter.
Reference is to be had to the accompanying drawings in which Figs. 1 and 1 are vertical central longitudinal sectional views of the two ends of a suction box constructed in accordance with this invention;
Figs. 2 and 2 are plans of the two ends of the same suction boxes;
Fig. 3 is a transverse sectional view on the line 3-3 in Fig. 2; and
Fig. 4 is a similar view showing a moditied form.
I have shown the invention embodied in the form of a suction box made up of two side sheets 10 and two horizontal sheets 11 and 12, these being secured together by angle pieces 13 and the box itself being secured to the Wooden plate 14: above it by angle pieces 15. All the parts above mentioned except the plate 14, are of aluminum or duralumin or of a similar alloy of alu1ninum. These plates are secured together by aluminum rivets 16 placed in the most advantageous positions. This makes up the main body of the suction box.
The suction box is made up of these parts and closed at the ends by cast aluminum end pieces 17 and 18. These pieces are made to fit the ends of the plates and are riveted thereto by aluminum rivets as shown in the drawings. They are cast with walls just far enough apart to fit between the side pieces 10 and also to lie just above the two partitions 11 and 12. In this way they are easily riveted to these plates and their extreme ends constitute flanges projecting down to the bottom of the suction box at each end. They are provided with the usual openings which need not be described in detail. By having all the metallic parts, including the 19, 1926. Serial No. 89,462.
rivets, of aluminum electrolytic action is of the aluminum plates and,'being cast, have integral flanges for securing them to the wooden plate 1 1. They are also provided with means, as usual, whereby the plungers 19 can'be guided through each end piece. One end piece 18 is connected as described and provided with a cast aluminum spout 2O bolted on at its end. Each end of the suction box is complete and sealed against the loss of liquor. The suction boxes of course are provided with the other features which are usually employed and which do not constitute part of this invention and need not be described herein.
In the form shown in Fig. 4 a simplification is provided by eliminating the angle pieces 13 and 15. This is done by originally forming the horizontal plates 21 and 22 in the form of channel pieces which are put in between the two side pieces 23 by riveting their side flanges thereto as indicated in this figure. The side pieces 23 are also formed with flanges 24: which obviously take the place of the angle pieces 15. In this way the suction box comprises two vertical sheets with angular tops and two horizontal channels constituting the bottom and horizontal partition. This construction is more simple and reduces the riveting very materially.
Such a construction, in either of the forms shown, is of great utility in the paper mak ing art because the liquids will not attack and destroy the aluminum and its durability is greatly increased. The parts of which the suction boxes are made are handled very easily because of their lightness and after the boxes are completed they are also handled easily for the same reason. The way of fitting the end pieces inside the ends of the made-up boxes is a matter of considerable importance because it furnishes a tight seal made most conveniently. The whole construction greatly increases the value and decreases the weight of these long suction boxes which heretofore have been quite heavy and hard to handle. I
Although I have illustrated and described only two forms of the invention I am aware of the fact that other modifications can be made therein by any person skilled in the art Without departing from the scope of the invention as expressed in the claims.
Therefore I do not Wislrto be limited to all the details of construction herein shown and described, but What I do claim is:
I. As an article of manufacture, a suction box for a paper making! machine comprising a pair of side plates of a metal consisting mainly of aluminum each extending in one piece from the bottom to the top and having a horizontal bottom and horizontal partition, each formed of a plate of the same metal, the bottom and partition being located entirely between said sides and riveted by aluminum rivets on the inner surfaces of said side pieces so as to provide a sealed joint along each side of the bottom and partition.
across the space between them and located entirely Within said space, all consisting of aluminum, a series of aluminum angle pieces connecting the partitions to the side plates at the corners inside and riveted to both, and a pair of aluminum angle pieces having the vertical flanges thereof riveted to the side plates near their upper ends and projecting out from their upper edges and for supporting a perforated Wooden plate.
In testimony whereof I have hereunto affixed my signature.
JOHN WVARREN VEDDER.
