METHOD OF FASTENING SOFT-METAL WEARING-SURFACES lN JOURNAL-BOXES.

SPECIFICATION forming part of Letters Patent No. 337,468, dated March 9. 1886.

Application filed April 2, 1885. Serial No. 161,074. (No model.)

To all whom it may concern.-

Be it known that I,DAN1EL A. WOODBURY, a citizen of the United States, residing in the city of Rochester, in the county of Monroe and State of New York, have invented a new and useful Method of Fastening Soft or Babbitt Metal Wearing Surfaces in Journal- Boxes, and for other Similar Purposes, of which the following is a specification.

It has been usual heretofore to cast such metal in place, either inclosed Within walls or I drawings, in which Figure 1 is an inside View of ahalf-box with the lining in place and secured. Fig. 2 is an end view of the same; Fig. 3, a transverse section through a stationary inclined box and the gate-block through which the metal to form the anchor is run; Fig. 4, a side elevation of the gate-block. Fig. 5 shows modifications in the mode of holding the anchors to the box. Figs. 6 and 7 show applications of my invention to the linings of different forms of connecting-rod butts.

The box A and its mate are bored out to the proper size and provided with suitable cavities or openings to receive the anchors or plugs O. The lining B is prepared by making a suitable casting and boring and turning it to fit, or by casting it in molds adapted to give it the exact form and dimensions required, or, what is better still, by first casting the metal into nearly the size and shape and then forcing it into exact dimensions by heavy pressure, thereby condensing and solidifying the metal; or it may be fitted in any other suitable way. The opening to receive the anchor may be formed in the mold or drilled after the lining is shaped. It is not necessary that these openings conform exactly in either size or position to the cavities in the box, but they ought not to vary much there= from. The lining is placed in position in the box and the gate-block D so placed that one of the gates at will receive the metal from a ladle and discharge it into the opening to be filled, as shown in Fig. 3. The metal used need not be the same as the lining; but an al- 10y is best that is strong and tough and will not shrink in cooling. Should the anchor shrink, however, it can be readily tightened by riveting it down a little, or by expanding it to fill by driving a small plug or some suitable pointed instrument into it.

The gate-block parts transversely through the center of the gates a a, to enable it to be removed before the sprue is broken off. A block provided with two gates in the forms shown will answer for filling openings in almost any position. In the absence of this block one may be improvised out of a piece of sheet metal witha small hole in itby bending it to the proper circle.

To obtain a gate of the required form, a dam, such as plumbers use, may be built upon the plate; or in the absence of anything better, one made of wood willsuffice. The block should fit the circle exactly and lie snugly in place. Then there will be only the place where the sprue joins to cut down to the surrounding surface. It covers so small a space that if out below, so as not to bear at all, it will do no material harm.

In many cases it is better to make an open ing through and pour the metal from the outside, as shown in Figs. 6 and 7.

My invention is also applicable to all flat wearing-surfaces where soft metal is used.

I do not confine myself to any particular form of anchor, as a cavity may be formed, and a screw, rivet, or something of a similar character set into it with the head projecting to form the anchorage, as shown in 0, Fig. 5;

i or a suitable cavity may be made for the metal with a screw reaching into it from the outside, as shown in G or a screw or rivet head may project above the surface and be embedded in what is practically the lining itself, as shown in C, and in other ways.

It will be seen that this method gives the lining a smooth and solid backing, and every time it is renewed it restores the wearing surface to its exact condition when everything was new obviating the necessity of a realignby casting metal anchorsinto suitable cavities ment of the shaft or other mechanism connector openings prepared for the purpose, sub- 10 ed therewith. stant-ially as shown and set forth.

hat I claim as my invention and desire to T 5 secure by Letters Patent, is- 7 DANIEL \VOODBURX' The above-described method of fastening \Vitnesses: ready-made linings or Wearing-surfaces in HENRY B. HOWE, journal-boxes and for other similar purposes, A. M. BASSETT.
