Application filed August 3, 1906. Serial No. 329,004.

and for various purposes, it is here ill'ustrated as applied to a track channeling machine constructed not only for cutting the usual channel groove, butspecially adapted for corner-cutting, that is, the cutting. of the channel groove into the acute angle or corner underlying the inclined side of a quarry wall.

In the specific embodiment of our invention the corner-cutting is effected by so mounting the tool support that, whileopcrating as usual in'the open part of the quarry it may be made to out from a fixed position of the machine under the overhanging side-walls while the tool swings along the arc of a circle lengthening the channel groove, delivering'its blows perpendicularly to the bottom of the groove and thereby losing none of theefi'ectiveness of its cutting stroke.

Our invention, having as it does other objects both connected with and disconnected from the above-mentioned aim, will be best understood by [reference to the following description, when taken in connection with the accompanying illustration of one ,spe cific embodiment thereof, while its scope will be more particularly pointed out in the appended claims: I

In the draw1ngs:Figure;1 isa central transverse sectional elevation of. a channeling machine embodying one form of'our in vention; Fig. 2 a view, diagrammatic its nature, showing themanner in which the,

{machine may be used for corner-cutting; Fig. 3 is. a front elevation of the channeling machine shown in Fig. 1, Fig.4isfa plan view taken section on the irregular section line in Fig. 1, and Fig. 5 is a sectional detailon the line 5-5, Fig. 3, show lng the locking pin.

Referring to the drawings and to the embodiment of our invention there submitted for illustrative purposes, the track channeling machine there shown is supported upon a frame work A which has journaled at opposite ends'the two transverse shafts a, carrying at their outer ends two pairs of flanged trucks a, the latter tracking with the rails 72, which are customarily laid upon the quarry bottom, and along which the machine, when cutting in the usual fashion 1 is advanced. y c

The machlne carries suitable tool-reciproeating motive means, which may be of any suitable form but whlch is here shown as a.

compressed. air direct acting engine, suppl ed with pressure from a suitable source (not shown) and having the piston c, cylinderC and the cross-head guides D. The,

cross-head E, which is connected to the piston by the piston-rod 0, has clamped thereto a suitable tool or tools, such as the gang 6 of three channeling tools shown.

partly broken away, the cutting ends of the latter, therefore, being given a reciprocatory' cutting movement to and from the bottom of the channel groove with the reciprocations of the engine piston. For adjustably feeding the tool toward the work as the channel groove deepens the engine cylinder and cross-head guides which are connected tomove as an unit, are carried by the cutter head or standard F, and may be advanced along its face by means of the fixed nut c on the cylinder and engaged by the longitudinal adjusting screw c which latter at its upper end'is journaled in an extension f of the cutterhead.

The cutter-head (Fig. 4) is provided with suitable guiding ribs orflanges f on which the engine cylinder and the attachedcrosshead guides are slidably retained by the gibs f and along which they may be adjusted longitudinally'by the adjusting screw 0 f The latter at its upper end is provided with a head f through which, by the attachment of a suitable tool or implement,

such as the ratchet lever" f (Fig. 1), the screw may be turned vand the engine and cross-headadvanccdtoward the work as the channel groove deepens.

To obtain the swinging movement of the tool lengthwise the channel groove during .corner cutting, the cutter-head F,.-is' supported at the side of the machine upon an oscillating or swinging support G, the latter comprising a circular plate or casting, having formed in its face (Figs. 3 and 4) a longitudinal guideway, in which the standard is adjustably clamped by means of the clamping-plates 7, which are bolted to the plate G. The clamping-plates hold the r v standard in fixed position, but the clamping- 'bolts may be loosened to permit it to be adjusted longitudinally, so that the entire standard with its attached cutting appliances may be dropped or advanced toward the work and clamped in .this advanced po- 'sition, as represented forexample in Fig. 2. The clamping-plates preferably extend, as shown, across the entire face of the supporting plate G, so that when the standard is adjusted to a more advanced position it is maintained in accurate alinement with reference to the center of the plate, the axis of tool action lying preferably across the oscillation center of the plate.

In order to provide I an oscillating or swinging movement for the cutter-head and thetool when the machine is employed for corner-cutting, the support G ismounted to swing through any desired arc in the main fsupporting-'frame H, which latter is mount ed at the side. of the, machine, as shown in Fig. 1. To permit the oscillating movement of the cutting parts the plate G has the centrally formed trunnion 9' j ournaled in a I bearing 71. formed in the-frame H, the said bearing being providedwith the removable lining h. The plate'is held in position by the cap 9., fastened to the' trunnion by the bolt g? and prevented from turning thereon by the pin 9 r When angle-cutting is desired, the main frame .H, is adjustable about an axis lengthwise the channel groove so that it may be inclined backward, away from the vertical.

, To permit'this adjustment it is fixedly secured at its base to trunnions 72 j ournaled in the main frame A. Itlis held fixed in either. an upright or an inclined position as maybe desired during cutting by any suitable means, such as the inclined brace-rod I, the latter linked at itsupper end to an ear 72. upon the back of the frame H and at its lower end to an ear 2' carried by a" bracket i removably bolted to a seat upon v, the main frame A. The brace-rod I is formed in'twoseparate piecesand provided with a suitable turnbuckle connection 2' by 7 means ofwhich its length may be taken up or extended to permit the necessary adjustw ment of the supporting-frame.

7 For reciprocating or oscillating the cutterhead during cornercutting, the back of the oscillating plate bolted to; a cir- 1,1so,6eo

cular actuating device such as the'annular worm gear J, meshing with an underlying driving worm j, the. axis of-the latter being coincident with the swinging axis of the frame 11, so that the worm remains in proper mesh with its gear irrespective of the adjustment of theplate upon the, trun- 'nions' 71. The back face of the plate G near its edges has a sliding'contact with the main supporting frame H at if, so that there is formed, in effect, a housing for the worm 7 gear, protecting the latter from dust and dirt. V

- washers may be taken up, a suitable checknut 'lc beingprovided to lock the same into position. V I 7 'Any suitable pmeans either manual or power driven for giving reciprocating driv-- ing movement to the worm gear J may be employed, but herein we have shown a special motive device comprising the tool-actuating fluid pressure engine L which turns the transverse driving-shaftl. The engine (not shown) and iscontrolled as to speed by V *the'throttlevalve Z (Fig. 4). The transverse shaft 1 carries at its 'end the beveled pinion m, which imparts opposite but equal rotation tothe two beveled gearsm and, m These may be separately clutched to or unclutched from the clutch-shaft m by the slidifi'g movement of the double clutch-member m*. The movement of the latter is effected through the shifting actuator m (shown only in Fig. 4 connected to the hand-lever m", the handle of which is conveniently positioned for graspby the operator.. The clutch member may be shifted by .the hand-lever to clutch either the gear m or the gear m to the shaft m or left 7 in an intermediate position wherein neither gear, engages the shaft and'the latteroremains stationary. r

The shaft m? has a pinion m which meshes with the gear, m on the countershaftmflthe latter journaled in a bracket m? on thefmachine'frame. The counter-. shaft also carries a gear m, meshing with the [idle gear m the latter engaging directly with the gear 111. which is fast upon andacts to drive directlythe worm-shaft j.

.13)? .1 9 .dmclfi ed transmission earing th 100 p is connected by the fiexiblehoseconne'ction Z .to the source of compressed air supply tool-actuating engine L, when in operation, turns the worm-shaft and causes a comparatively slow swinging movement of the cutter-head upon its trunnion simultaneously With the rapid chopping action of the tool under the influence of the stool engine C. When the swinging movementhas advanced far enough in one direction the actuator m may be thrown and the swinging movement reversed. A power actuation of the swing ing support is preferable sinceit not only renders the machine more mechanical but better insures a uniform swinging move ment and the preservation therefore of a true are at the bottom of the channel groove.

During the cutting of the ordinary channel groove the channeler is caused to traverse the trackway as usual and the cutter head is held fixed in the usual fashion. To throw out the oscillating movement of the cutter-head under such conditions the idle gear m is slidably mounted on the stud m, so that, when desired, it may be slipped out of mesh with its two engaging gears m and m, and thetransmission gearing thereby thrown out of engagement. This leaves the cutter-head fixed in position, the worm holding it against movement. If desired, a locking-pin h (Fig. 3) may be used to effectually lock the swinging plate against movement relatively to the sup porting-frame H.

During the cutting of the ordinary chan nel groove the necessary traversing move ment is given to the machine carriage through the clutch-shaft m which carries at each end a worm n meshing with. an underlying wormrgear n secured to a carriage-shaft a. Through this means the carriage may be moved under its own power along the rails in either direction, according to the position of the clutch'm the same power driven member, namely, the shaft Z acting to swing the tool or advance the carriage as may be required.

During cornercutting it is desirable to maintain the carriage stationary, and we have herein shown means for lifting the trucks of the machine clear from the track and there rigidly holding the machine during the swinging movements of the tool. For this purpose there is provided at each corner of the machine frame a lug O, which lugs are vertically threaded tolreceive the jack-screws 0 (Fig. 3) the latter having feet which aline with the top of the rails. The enlarged feet of these screws fit a socket in a split clamp 0, the two halves of which may be clamped securely to the under side of the tread of the rail by the transverse clamping screw 0 VVhen the clamping screw is tightened the clamps grip the rail, preventing movement of the machine. Before' clamping, the jack-screws are turned to lift themachine high enough to free the in the ordinary fashion with the supporting-frame held either vertically or inclined backward for angle-cutting. The overhanging side of the wall of the quarry, however, determines the limit of vertical cutting and when this is reached the machine is clamped to the rails, the worm gear turned to, tilt the cutter head forward at any desired angle, and the tool then given, in addition to its usual reciprocatory movement to and from the work, an oscillating movement as well through any desired angle, so that the tool travelslengthwise the channel groove in an arc-like path and its blows are delivered radially from the center of oscillation of the cutter-head. For example, referring to Fig. 2, the machine there shown is clamped to the rails B and engaged in mak-' ing the corner cuts for a channel groove transverse to the previously completed channel grooves 1, 2, 3 and 4, which with the exception of the groove 1, have been out upon an angle. As represented in Fig. 2, the cutter-head has been swung forward by movement of the worm gear and is being oscillated by the tool-actuating engine L through the angle between the channel grooves 3 and 4, successive cuts being represented by the dotted arcs 5. After the too] has cut to the bottom of groove 3, the bottom of the new transverse groove is left flat or horizontally by stopping the return swing of the tool short of the full angle.

It will be seen that the described machine is quite universal in its construction, and, the tool carrier being sustained at substantially 'a mid position lengthwise the machine, so

that it may be forwardly inclined from either end, corner-cutting from either end. thereof, and at any angle which practical quarry requirements demand, may be readily effected without necessary change in adjustment of the supporting frame H. The construction and shape of the machine furthermore permit its construction at a very low height, so that it can be moved well into the corner of an inclined quarry wall.

The adjustment of the cutter-head to and from the work which is permitted by the clamping-plates H permits the corner-cutting to be done, particularly at extreme angles, with tools of much lesser length, since by this adjustmentthe' cross head may be brought, in substantially the same close relation to the rock in corner-cutting and angle cutting as in upright cutting. This will a carriage. This 7 adj ustment' renders the tools easier to handle, as well as effecting a saving in their cost. For example, in the described machine a saving of 25 per cent. in the weight and length of the tools may be effected through this adjustment when out ting at an angle of 34 for the corner of an upright cut approximately six feet deep. This adjustment, inasmuch as it lowers the standard (see Fig. 2) also decreases the height of the machine when corner-cutting, permitting it to be advanced further into the corner.

While we have shown and described one form of our invention for the purpose of illustrating the same, it is to be understood in details of construction and relative arrangement of parts, as well as the application here made of the invention,the described embodiment may be widely deviated from without departing from the spirit of the invention.
