MACHINE FOR REDUCING BRASSES OF JOURNALS.

SPECIFICATION forming part of Letters Patent No. 483,956, dated October 4, 1892.

Application filed October 14, 1891. Serial No. 408,729. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD FERRISS, a citizen of the United States, residing at Alta, in the county of Placer and State of California,

5 have invented a new and useful Machine for Reducing Brasses of Journal Bearings, of which the following is a specification.

The object of my invention is to produce a machine for reducing the brasses of journaland combination of parts, as hereinafter described, by which I have produced a simple, portable, and handy machine for finishing the faces of journal-brasses more rapidly and more perfectly than has heretofore been possible under the ordinary methods of finishing by hand or in a lathe.

The following description explains the manner in which I proceed to construct my said machine, the accompanying drawings being referred to therein by letters.

Figure 1 of the drawings is an end elevation of the machine. Fig. 2 is a side elevation with a portion of the bed broken away. Fig. 3 is a side view of the cutters, partly in section.

A is the bed of the machine, having a post A in the center of one end and a cross-head B at the opposite end, or what I have termed the head, of the machine. The sides of this bed are raised above the bottom and are finished true and smooth along the top edges to form wings for the moving planer, and these sides at the head of the machine extend above the ways and form posts to carry the crosshead B. This part is fixed on the posts by top-bolts, as shown in Fig. 1, and is elevated sufficiently above'the ways to let the planer pass under it.

B is the standard in the center of the crosshead, having a square eye or opening B to take a sliding arm 0, on the end of which is a threaded socket O fora clamping-screw D, with a flat bottom end and a hand-wheel on top. The oifice of this screw is to hold the brass down against the planer, and it is set in position by shifting the arm 0 in the post B E is a sliding plate fitted to slide on the ways at the sides of the bed and between the uprights at the head of the machine on which the cross-head is fixed.

bearings; and it consists in the construction.

Two plates F F", each with a beveled cutting-edge f and about one-half the length of the slide, but of corresponding Width, are fixed on the top face of the slide by screws f 2 f which set through the slide from beneath, in order to leave the top surface smooth,and g is a shim orthin metal plate inserted between the plate F and the carrier E, to raise the beveled cutting-edge the desired amount above the face of the other plate F to produce the cut. The depth of cut or thickness of the shaving that the cutter will make in moving under the brass is varied by changing the shim g for another of diiferent thickness. This is a simple and effective mode of regulating the depth of cut. It will be noticed that while both planing-irons have beveled cutting-edges the planer F, or the one nearest the post A, is the cutter, and the other iron holds and presents the brass in a horizontal or level position to the cutter and that the end of the plate F which is set to ward the beveled edge of the plate F, may be square, as well as beveled, so far as the cutting-operation is concerned. The object of constructing the two plates F F of the same size and with cutting-edge on each is to make them interchangeable, so that when the plate F is worn dull or the edge becomes broken the plate F may be turned and set in Working position, while the plate F is substituted in its place.

- I is a long screw-rod with a capstan-head and hand-bar J working in a screw-threaded bearing in the post A in line with the end of the sliding planer and having its point set against a clip or loose block h, that takes the thrust of the screw. This piece has turnedover ends to set over both plates E F and is used to distribute the pressure of the screw against the ends of both plates.

In the operation of my improved machine the cutter-plate is run back to the post A and the brass W is set on the level surface of the plate F with the end resting against the cross-head B, after which the clamp-screw is turned down upon the brass. The cutter is then fed forward bymeans of the screwI with a slow even movement until the cutting-edge has passed across the face of the brass. In this manner the piece can be operated on several times until the desired quantity of metal 1s removed.

Having thus fully described my invention, What I claim, and desire to secure by Letters Patent, is-

1. The machine for reducingjournal-brasses herein described, consisting of a suitable bed having at one end a cross-head B and a supporting-standard B for a clamp-screw and at the other end a post A for a feed-screw I, a sliding plate E, having a planer-iron F and a plate F to hold the brass to the cuttingedge of the planer, and the adjustable arm 0 and clamp-screw D, combined for operation as set forth.

2. In a machine for reducing brasses, the combination, with the stationary bed having a cross-head and means for holding the brass against vertical movement at the cross-head, of the sliding plate E, having interchangeable planer-irons F F with beveled edges, and a feed-screw to move said plate, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
