SPECIFICATION forming para of Letters Patent No. 658,277, dated september 1s, 1900.

Application filed April 13, 1900.

To all whom it may concern:

Be it known that We, CHARLES C. NEWTON and ELLIS J. HAN'NUM, citizens ofthe United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Radial Planing-Machines, of which the following isa specification.

The object of our invention is to so construct a planing-machine that it will plane curved surfaces, especially those struck from a common center-such, for instance, as the saddles of locomotive' cylinder-castings.

While the machine is particularly adapted to planing the saddles of locomotive cylindercastings, it can be used for any purpose Where it is desired to plane a curved surface.

In the accompanying drawings, Figure l is a perspective view of our improved radial planing-machine. Fig. 2 is a plan view. Fig. 3 is a side View. Fig. 4 is a vertical sectional View on the line 4 4, Fig. 2. Fig. 5 is a View on the line 5 5, Fig. 4. Fig. 6 is a plan view of the base with the standard removed, and Figs. 7 and 8 are views of details of the machine.

A is the base of the machine, on which is mounted the standard B, carrying the head C, on which the cutting-,tools are mounted.

A is a bed on which the Work to be planed is placed. This bed has a series of transverse grooves a, which receive bolts for securing the work to the bed. On the bed are supporting-tables D, (two in the present instance,) made in three sections, the first section d of each table being secured to the bed A' by clamp-bolts which extend into the grooves a, and on this section d is mounted a section d', which slides longitudinally thereon. A feedscrew d3 is used for adjusting the section d. On the section d is a section d2, mounted to slide transversely thereon and fed by means of a feed-screw d4. By arranging the tables in this manner they can be readily adjusted to accurately support' the cylinder-casting or other article to be planed. We have shown by dotted lines in Fig. 2 the cylinder-castings of a locomotive in which the tWo cylindercastings are secured together, forming a comberial No. 12,772. (No model.)

plete saddle, and this is one of the articles Which our invention is especially designed to plane.

On the base A is mounted a circular platform E, and on this platform are ways e e for` the vertical screw b for raising and lowering the tool. This screw b is connected to a hand-shaft b2 through chain gearing b3 and intermediate shaft b4, so that on turning this vshaft the head C can be adjusted vertically.

On the head is a swiveled tool-carrier C', carrying the tool-clamp c, of any suitable form. The screw-shaft b is geared to a rearwardlyextending shaft B', mounted in bearings on the base of the standard B, which has an arm b5 connected to the shaft by ratchet mechanism. (Shown in Fig. This arm strikes the adjustable blocks f, one on each side of the center line, and these blocks are adjustable in a radial slot a' in the base A. By this arrangement the vertical feed of the tool is provided for. Y

The ratchet mechanism is constructed as clearly shown in Figs.7 and 8. The shaft B" longitudinally on the shaft by collars s', se-

cured to the shaft by set-screws. The arm b5 is carried by shoulders on the ratchet- Wheel and has a spring-pawl s2, which engages the teeth of the ratchet-Wheel, so that it will feed the shaft B only in one direction, one block f causing the paWl-arm to feed and the other block returning the arm to its origi-|` nal position. l Motion is imparted to the standard B through the driving-shaft I, on which 'are the pulleyst't" This driving-shaft is geared" t'o the shaft I', on Which is a Worm 12, geared to a worm-Wheel J secured to the underside of the circular platform E, as shown clearlyA in Fig. 4. The hub of this Worm-wheel ex.- tends into a suitable bearing A2 in` the base A of the machine, and the rim of the wheel also fits snugly in the upper portion of the base, as shown in Fig. 4C.

In order to shift the belt at the proper time to reverse the lateral movement of the platform E, carrying the standard` B and its cutting-tool, we mount ou the edge of the platform lugs or projections e2. instance these lugs are secured in place by T-headed bolts, which enter a T-headed slot cut in the periphery of the circular platform, so that the lugs can be adjusted to any point desired, and thus the radial movement of the tool is regulated.

A lever E' is pivoted at e3 to the base of the machine, and one arm of this lever is in the path of the lugs or projections e2, so that it will be struck by either one of the projections, as shown in Fig. (i. The other arm of the lever E is connected to the rod e4, which in turn is connected to a lever G, pivoted to` the belt-shifter G', having arms which shift the belts from the fast to the loose pulleys. Thus, as shown in Fig. 6, one projection e2 is in the act of striking the lever E' and will shift the belts, so that a reverse motion will be immediately given to the platform E,and this motion will continue until the other lug e2 will strike the lever on the opposite side and will again shift the lever and the belts, so that it will be seen that by shifting the lugs on the platform more or less radial movement can be obtained.

The operation of the machine is as follows: If, for instance, a locomotive cylinder-sad dle is to be planed, the supporting-tables D are adjusted on the bed A" in proper position to receive the cylinder, as shown by dotted lines in Fig. 2. The curved portion of the saddle is placed in proper position to be planed by the tool. The standard B is adjusted by means of the screw e', so that the tool will be in position to plane the saddle on the proper radius. The projections e2 are adjusted on the periphery of the platform E, so that the belts will be shifted as soon as the tool finishes its work at each stroke and the blocks ff are adj usted in the radial slot, so as to feed the tool forward at the end of each stroke. The machine is then set in motion and the entire surface of the circular portion of the saddle will be planed off on In the present` 2.
