IMPROVEMENT IN APPARATUS FOR REPAIRNG KNOTTER. STRAINER, 0R SCREEN PLATES 0F IPAPER-MACHINES.
Specification forming part of Letters Patent No. 140,166, dated J une 24, 1873; application filed November 9, 1872.
To all whom it may concern Beit known that I, JAMES ROBERTSON, of Lasswade',-i-n the county vof Mid Lothian, Scotland, have in'vented a new and useful Improv ement in Apparatus for Repairing Knotter, Strainer, o r Screen Plates of Paper-Machines, of which the following is a specification: 1
Figure 1 represents a strainer-plate secured `to theblotwor bed. Fig. 2 is a detail longitudinal section taken through the line :v 4v, Fig. 1. Fig. 3 is a detail cross-section taken through the liue'g/ y, Fig. 1. Fig. 4 is a detail cross-section enlarged and showing the tool iu place. Fig. 5 is a side view of the tool.
Similar letters of ref rence indicate corre spending parts.
My invention has for its object to furnish an improved apparatus for repairing strainen plates, the slots ot' which have been widened by the wear and the corrosion due to the straining actio and the acids in the pulp, so as to enable the said plates to be again used; audit consist in the mode of lesseningor reducing the slots in a strainer-plate, in the tool constructed as hereinafter shown and described, to adapt it for use in reducing -the slots in a strainer-plate, as hereinafter set forth.
A represents the strainer-plate, about the construction ot' whichthere is vnothing' new.
B is the table,block, or bed, upon which the plate A is laid, to be operated upon. The bed4 B is made of iron, suiiicieutly heavy to support the plate A iirmly, and which may be strengthened with ribs or flanges, either or both, upon its lower side. The bed B may I be provided with legs of such a lereth as to raise the bed to a convenient heigw. (l are clamps extending across the plate A, and the ends of which are bent downward and inward to overlap the lower side of the bed B, as shown in Fig. 3.' In the clamps C are formed screw-holes, in which are inserted the y screws D, the forward ends ot' which' rest ngainstbars LE, laid upon the plate A be- -neath the clamps O, as shown in Figs. 2 and 3, so that by turning the screws AI) forward the plate A will be pressed down rmly upon the bed B. The plate A is further secured to the bed B by the edge-clamps F, which cross the edges ot' the plate A and bed I3,
and the ends of which overlap the upper v'side of the plate A and the lower side ofthe bed' B, as shown in Figs. 1, 2, and 3,.where .they are secured in place by wedge-keys G, as shown in Fig. 2. H is the body or shank of the tool, the lower end of which is slotted to receive the blade I, which is secured iu place by screws, bolts, or other convenient means. The blade I must be of a thickness exactly equa-l to the required width of the slots in the plate A. The lower end ot' the shank orhandle H is so formed as to press or draw the metal of the plate A, at the edges of the slots in said plate, inward against the sides of the blade I, thus reducing the size of said slots.
In using the apparatus the plate A is secured to the bed or block B, in .the manner hereiubefore described. The blade I is then inserted-in theslots of the plate A, and baa..
iew blows of a hammer -upon the upper end of thc handle H the metal ofthe plate A will be drawn or packed against 'the blade I, reducing the slot again to the required size, the blade-I acting as a gage.
The plate A, when repaired in this way, is
even better, and will last longer, than when new, as the metal is compressed along the slots and is thus better adapted to resist the wea-rand the action of the acids.
One or both the side edges of the blade Inlay project in hook form, as shown iu Fig. 5, so that it may be used for clearing the slots before reducing their width.
Having thus described my invention, I claim as new and desire to secure by Letters Patent l. The mode of lessening or reducing the slots in a strainer-plate, substantially as hereiu'shown and described, and for the purpose set forth.
2. The tool II I, constructed substantially as herein shown and described, to adapt it for use in reducing the slots ina strainer-plate, as
set forth.
