SPECIFICATION forming part of Letters Patent No. '747,868,'dated December 1903- Application filed April 17, 1903- Scrial No. 153,082. (No model.)

To all whom it may concern.-

Be it known that I, CHESTER T. DRAKE, a citizen of the United States, residing at Chicago, county of Cook, Stateof Illinois, have invented a certain new and useful Improvement v in Excavating-Machines and I declare the a following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains to make and use the same,referen ce being had to the accompanying drawings, which form ,a part 0 this specification.

My invention relates to certain improvements in excavating-machines of the same class as that described and shown in my concurrently pending application for excavating-machine, executed of even date herewith and filed April 17, 1903, Serial No. 153,083;

The present invention relates more particularly to the mechanism for revolving the cutter-shaft and to the other features hereinafter described and claimed. 1

In carrying out the invention I will describe only briefly those parts which are more elaborately described in my above-mentioned concurrent application.

A rep rese nts the framework; B B, the

trucks; C, the rails; D D, the endless-belt carriers; E; the cutter-shaft; F, the cutter; G, the spiral conveyor back of the cutter for carrying ofi the earth; H, the revolving frame gtowhich the shaftis engaged and by means fof which the end of the shaft carrying the cutter is caused to travel in a circular direction that is, an orbital revolution; H, the gear which meshes with the worm on the shaft H H the sprocket-wheel on the end of said shaft H H a sprocket chain connecting the sprocketwheel H with the sprocketwheel H on the counter-shaft H and J the motor from which the power is derived.

I will now describe the mechanism for supporting and revolving the shaft E.

K is a suitable standard supported on the frame A and forming the bearings for the various shafts, as shown in Fig. 5. It will be observed that the shaft E extends on both isides of the standard K and that the driving- @gears, form more or less of a counterweight for the long end of the shaft.

Supported by this standard, preferably by a roller-bearing m, is an upright bearing M. On the shaft E is the ball E, which is carried in the circular bearings M M of the upright M. On the inner or rear end of the shaft E is a counterweight E and a beveled gear N. On the end of the shaft is a ring 6, keyed to the shaft. The counterweight E is in the form of a collar which surrounds the ring e.

e is a fitting,(shown in Fig. "9) engaged to ithe counterweight E as shown.

Meshing with'the beveled gear N is a beveled pinion O on the counter-shaft 0', the latter being supported by the fitting e on the counterweight E 0n the counter-shaft O is a sprocket-wheel 0 connected by thethe shaft P, as shown in Fig. 4. On theshaft P is a beveled gear P, which meshes with the beveled gear P on the shaft P This shaft P is supported by the upright M and by the arm 7c of the standard K. On this counter-shaft P is another beveled gear P", which meshes with the beveled pinion P on the shaft P", the latter supported by the arm 7t of the standard K and by the loose fitting K on the upper end of the shaft P On the shaft P is the sprocket-wheel P The sprocket wheel P is connected by the sprocket-chain P with the sprocket-wheel R on the shaft R, the latter supported by suitable standards extending from the frame A. The shaft R is provided with the gear R which meshes with the gear R on the shaft of the motor J. On the end of the shaft R is a pinion R", which meshes with the gear H on the shaft H The operation is as follows: The revolution of the axle of J is transmitted through the pinion R gear R sprocket-wheel R, sprocket-chain P and sprocket-wheel P to the shaft P thence through the beveled gears P and P shaft P beveled gears P and P to the shaft P, thence through the sprocket-wheel O sprocket-chain O and sprocket-wheel O to the shaft 0, thence through the beveled gears O and N to the shaft E, thus revolving the latter. At the same time the pinion R on the shaft R meshes with the gear H on the shaft H and thus through the sprocket-wheel H and chain H and sprocket-wheel H the shaft H is revolved, and thus the frame H revolved. The ball E on the shaft E being supported by the circular bearings M M permits the outer or cutter end of the shaft E to be moved in any direction, either horizontally or vertically, or at an angle. This of course will give an opposite movement to the inner or counterweight end, and consequently to the gear N. Any vertical movement or movement in an up-and-down direction will be compensated for by the gear P simply revolving against the face of the gear P while any horizontal movement or movement in a sidewise direction will revolve the upright M on its ballbearing m, and the latter will carry with it the standard M and consequently all the mechanism on the shaft P and all the mechanism supported on the shaft 0. Thus the shaft E while continuously revolving may be tilted in either a horizontal or vertical direction without disturbing the mechanism for revolving it.

Another feature of my present invention is the mounting of the frame A and the mechanism supported thereby by a bearing S, Fig. 23, on the frame and a socket S on the truck B and a bolt S to hold the parts together. I also provide on the truck B a strip B having perforations B and also the channel-irons a a, on which the piece A of the frame rests. The piece A is provided with a bolt A which enters the orifices of the strip B so that when desired the frame A, as well as the cutter-shaft, maybe thrown in a horizontal direction to an angle to the length of the side of the excavation, and thereby enabling the cutting of a greater diameter of excavation than as though the adjustment were confined to the cutter-shaft.

Another feature of my invention is the provision of mechanism for preventing the revolution of the cylinder T, which surrounds the spiral conveyer G, on the outer end of the cutter-shaft.

U is a frame extending out from the main frame A.

V is a frame, and pivoted therein is an upright rectangular frame consisting of two upright bars 12, within which the frame T, extending from the cylinder, slides. The frame V is provided with two horizontallyextending arms 1 which pass through orifices in the frame U. Now, as will be seen, when the cutter-shaft moves vertically the frame T will slide up and down between the bars 1;, and when the shaft moves horizontally the frame V will slide horizontally on the arms n. Thus the cylinder T is constantly held from rotation, while at the same time it can accommodate itself to any of the movements of the shaft E.

In Fig. 13 I have shown a variation in the form of the cutter and its accompanying spiral conveyer. W is the conveyer, supported by the arms to on the shaft and revolved by the gears w and 10 connecting it with the counter-shaft.

I wish it understood that in the present application I have shown and described several features which are not broadly claimed in this invention, but which are also shown, described, and claimed more particularly in my concurrently pending application, filed April 17, 1903, Serial No.'153,083.
