with the use of a cupped grinding wheel such as the wheel 1L- This use of the cupped grinding wheel is in itself a highly beneficial improvement in rail grinding. In the use of a grinding wheel applying its periphery to the rail, the conditions are such that there is excessive bounding and chattering of the wheel on the work, producing such vibration and accompanied with so much lost motion in-the bearings that it is very diflicult to do satisfactory work except with a very heavy machine. The cfipped wheel, grinding with a plane annular surface at right angles with its axis, grinds across the face of a rail in two directions at the same time, in region's sufiiciently separated along the rail to insure steadiness of the wheel and practically eliminate the bounding and chattering so objectionable with the peripherally engaging. grinding wheels. I I
While it is thus desirable to apply the '7 cupped wheel to the rail with upright arbor,
it is also desirable to use other wheels, such as a wheel forLroughing and throat-grinding.- There are alsoother tools to be rotated by power in track work. such as drills and reamers, which it is desirable -to drivebv the same motor; also the grinding of tools readily without taking them far away from the work is desirable. I therefore provide means for adjusting the motor 2 to, a position with its'shaft or arbor 1 having its axis horizontal as shown in Fig. 3. where the peripherally-grinding wheel 7 is mounted in a hand piece 8 and connected to the arbor 1 by a flexible shaft 9. Thusthe wheel 7 may be applied to any part of the track or other work in any position. The wheel 10. indicated by dotted lines. may be secured on the arbor 1 if the flexible shaft 9 be removed. and is thus available for tool grinding.
In its horizontal position, the arbor 1 simply turns in a, bearing 11 at the commutator end of the motor. and in a bearing 12 at the other end. under the same conditions as are found in. the operation of any motor with horizontal armature shaft, but, to carry the arbor in its upright position, the bearing 12 is supplemented by an endthrust bearing 13. On the commutator end 1 of the motor, anv adjusting screw 14 is mounted in a yoke 15 that arches over the bearing 11, this screw engaging the end of the arbor or shaft 1 to adjust it axially and take up any end thrust which it may have,
thus eliminating even such slight amount of chattering as would otherwise be incident to the operation of the cupped wheel 4.
By the above means, very accurate results are obtained by ,proper adjustment of the grinding wheel to the surface to be ground.
For affording this adjustment, the entire- 22 fixed oh the screw. This screw has the hub 19 for its nut, and thus carries the entire weight of the slidable base 16 and the motor and. other parts mounted thereon.
The screw 20 extends a' suitable distance above the bracket 21 and has a hand wheel 23. When this screw 20 is turned by the hand wheel and with the face plate 17 forming an accurate guide for the entire motor in axial direction, it is possible to accurately regulate the closeness of the 'grinding wheel to the work.
It is alsodesirable to adjust the angle at which the grinding wheel 4 is applied to the railor other track part, such as for grinding rails on elevated curves and for facilitating difiicultoperations in other parts of the track. I provide for this adjustment of inclination, and also for the complete horizontal adjustment, by pivoting the face plate 17, at its lower end. This pivoting of the face plate 17 is accomplished by means of hinges 24 connecting the face plate to hubs of the hinge bar 25 that .extends along the lower end of the face plate. These hubs embrace the rear and front tubular frame bars 26 and 27 which extend parallel at right angles to the hinge bar and flank the motor 2. The rear frame bar 26 has, to the rear of the motor, a fork 28, receiving the rear track wheel 29 and a similar fork 30 on the front frame bar 27 in front of the inotor, carries the forward track wheel 31. These wheels run on the rail that is being ground. Near the other ends of the frame bars 26 and 27 are the fork 32, with the other rear track wheel 33, and the fork 34 with the other front track wheel 35 which wheels run on the otherrail of the track. These forks 32 and 34 are joined by a tubular strut 36, running parallel with the track rail. A clip 37 1s secured around this strut 36 and receives the eyes of rods 38 and 39, pivotally held therein by a pin or bolt 40 through the end parts of the clip and through these eyes. These rods 38 and '39 have their other ends threaded and entering turn-buckles 41 and 42 I which have hand wheels 43 and 44 and receive the threaded ends of. other rods 45 and 46, respectively. Thus, the rod 38, turnbuckle 41, and rod 45 makeup an upper connecting element, and the rod: 45- has an eye that is brought between cars 47 at the middle of the upper end of the face plate 17 with a pin 48 passing horizontally therethrough, therebyi permitting pivotal movements of the connecting element with respect to the face plate in the vertical plane of the swinging of the face plate. The connection of this element with the clip 37 by means of the bolt 40 is sufficiently loose to provide the required articulation at that point. By rotating the turn buckle 41 by means of its hand wheel 43, the rods 38 and 45 will be screwed toward or away from each other, thus shortening or lengthening the connecting element which they make up, with the result that the motor is inclined more or less toward the inside of the track,
thus affording the required adjustment of the inclination of the grinding wheel 4. In the lower connecting element, made up of the rod 39, turn-buckle 43, and rod 46, the rod 46 has an eye lying on top of the hinge bar 25, at its middle, with a bolt or. pin 49 through the eye securing the connection to this hinge bar. The hubs of this hinge bar are loose on the frame bars 26 and 27, and when this lower connecting element is shortened or lengthened by the operation of the turn-buckle 42, the entire face plate and motor, and the parts carried thereby, are adjusted bodily toward the inside or outside of the track, thus governing the position of grinding wheel transversely of the rail. By manipulating both connecting elements, the grinding wheel may be made to bear upon the rail within any desired region of its annular plane surface and to engage at any required angle. The manipulation of the hand wheel 23, adjusting the parts axially, is also involved in this adjustment.
To bring the motor and other parts to the horizontal position, 'the pin 48 is withdrawn, disconnecting the upper connecting element from the face plate, and the entire upper connecting element is swung aside, pivoting on the pin 40 at its other end, permitting the motor and other parts to be swung upward, and bringing the ears 47 down to embrace the ear 50 on a supporting bar 51 that has hubs embracing the frame bars 26 and 27. This bar 51 thus supports the motor in horizontal position, and the pin 48 is inserted through these ears to hold the parts in this position. The upper connecting element simply rests beside'the motor as seen in Fig. 3.
The motor is supplied with current through the flexible cable 52 leading from the controller-box 53, Which is mounted on the frame bars 26 and '27 near the side of the machine opposite from the motor. Through this controller-box, suitable connect-ion may be had with the trolley wires or other source of current along the track.
The track wheels, and especially the track wheels 29 and ,31 that run on the track rail being ground, are preferably turned true, thus adding to the accuracy of the grinding.
The front track wheels 31 and 35 are loosely mounted on spindles 54 and 55 in the forks and 34. respectively. To suitably reenforce these forks, a tubular bolster 56 extends from one fork to the other across the track. The rear track wheels 29 and 33 are pinned to an axle 57 extending across the track and journaled in the forks '28 and 32. A spur pinion 58 is fixed on this axle 57. and the bifurcated yoke pieces 59 have members bearing on the axle 57 'and flanking this pinion. The other members of the yoke pieces The feed lever 66 has bifurcations 67 thatflank the gear 64 but come between the yoke pieces 59. and pivots on the pin 65 that forms thebearing for the gear 64. so that the lever is concentric with the gear 64. Thislever 66 has a detent 68 pressed down by a spring 69 and raised by a pawl 70 on the handle of the lever, Vhen this detent is raised, the lever may be swung around the gear 64, and the detent'68 may descendbetween any two teeth of the gear. By this means, the lever 66 may be swung backward or forward with the detent disengaging. and then; engaging, swing forward or backward and rotate the gear 64 accordingly. This moves the entire machine forward or backward along the track, by the driving action of the'gear '64 through the pinions 62 and 58 and the axle 57. to the track wheels '29 and 33. bearing on the rails. The idler pinion 63 is interposed so that a swing of the lever will drive the machine in the same instead of an opposite direction. The operator stands to the rear of the axle 57. just inside the rail being ground. and by manipulating the lever 66 may feed the machine along the rail to produce the exact grinding efl'ect desired and may reciprocate the. machine along the rail as required. At the same time. the hand wheel 23, for adjusting the closeness of the contact of the grinding wheel with the rail, is also readily accessible, while the operator stands in such )moderate distances. as from one railjoint to another, or as from one switch to another. 'ith the detent thus released, the gear 64 revolves freely as the machine runs along the track. For transporting the machine considerable distances, it is moreconvenient to place it upon some other vehicle such as a car or wagon. To facilitate the handling of the machine for transportation in this way. or for removal from the track whenever desired to allow traffic to proceed or for the use of the machine with the motor in horizontal position, I provide the transfer wheels 71 and '72 turning on pins 73 and 74 in forks 75 and 76 respectively, which forks are connected by a bolster 77. These forks 75 and 76 are preferably integral with the forks 28* and" 30" that receive the track wheels 29 and 31 adjacent to the motor. and extend transversely outside the track bein ground. The frame bar 27 extends into. this: forks 73 and 74, and they along with the forks 28 and 30 are rigidly secured to these frame bars as before mentioned. Thus mounted, the axial line of the wheels 71 and 7 2 is parallel to the track rail. and the wheels; which merely have plain rims to bear on the surface of the 100 road or street. are carried by these forks at such a height that when the end of the machine at the other side of the track is raised a convenient distance. the motor end of the machine will be carried on these wheels 71 and 72. and the flanges of the wheels 39 and 31 will clear their track rail, so that the machine may be pushed transversely off the track. For handling the machine in this way. the frame bars 26 and 27 have a tubular handle bar 78 secured in blocks 79 extending up from the frame bars near the ends thereof. The ends of this handle bar 78. as well as the adjacent ends of the frame bars 26 and 27. are closed by caps 80. By these means the machine, with a motor of ample power and all other parts in proportion. is readily handled by two men. since most of the heavy parts of the machine are located at the motor end. which is carried on the transfer wheels. giving the men *a long leverage when they pull upward on the handle bar 78. Thus. not only is the machine made light in proportion to the work it is to do. but suchweight as it has is described.
While I have specifically shown and dev to secure by Letters Patent is:
