EDWARD A. EVERETT, OF NEW YORK, N. Y.

TRACK-DRILLING MACHINE.

Specification of Letters Patent. Patented Sept. 27, 1921.

Application filed March 3, 1919. Serial No. 280,208.

To all whom it may concern:

Belt known that I, EDWARD A. EVERETT, a citizen of the United States, and resident of New York, in the county of New Fig. 2 is an elevation in a plane at right angles to the plane of the track, Fig. 3 is a plan view of the machine, Fig. 4 is a de tail of its application, Figs. 5 and 6 show details of the construction and Fig. 7 is a modification.

The gasolene motor 11 is supported by the carriage 12 to which it is adjustably secured by the plate 13 havingthe slot openings 14 for the attaching bolts. This carriage is mountedv upon rollers 15 which roll on the head of the rail 16 as the machine is moved along the track. The shaft 17 is connected to the. engine or motor 11 by the coupling 18 and drives the pulley 19, which, by the belt connection 20 drives the pulley 21 which in turn drives the spindle 22 carry- .ing the drill 23 to engage the web of the rail 16 as shown in Fig. 2, this construction being similar to the common form of drill press. To increase the tension of belt 20, the friction controlled roller 24 is provided which is made efiectiveby the handle 25 held in position by friction against the frame by the bolt26. i

The drill is fed forward by the long vertical handle 31'pivoted at 33 and, having a clutch at the lower end 34 engaging the clutch ring 36 on the end ofthe spindle 22 which is thereby moved back and forth inresponse to movements of the handle. A coil spring 35 is provided as shown 1I1 Fig. 2 to normally hold the .drill away from the ra l. The long end of the handle 31 is secured in asocket 32 to make it easily detached.

Usually it is desired to drill a rail on the neutralaxis as shown in Fig. 2, the size of rails however varies, also, the end of the a I ties 51, 52 vary in height due to curvesand to irregularities on their surface. Now it will be observed that the position of the drill 23 is fiX ed'by the roller 15 on the rail head. The height of the carriage 12 with relation to the roller is, therefore, adjust able by means of the eccentrics 41 supporting the axis of the rollers 42 which may be rotated to bring the drill into the position desired. Set screws are provided as shown to lock the eccentrics in position. The drill spindle is held in alinement with relation to the rail by means of the foot 43 resting across the ends of the ties as shown in Fig. 1. This foot turns on a'pivot 45 and may be turned upward out of the way of obstructions when the machine is rolled along the track. .VVhen set for drilling, this foot rests upon the ties, the drill is alined and pressure is applied to the foot pedal 44 whichlocks it in position. This construction will be understood by reference to Fig. 6 where thejaws 47 are shown supporting the pivot 45 uponwhichthe foot 43 and the pedals 44 are mounted. The hub 46 of the pedal 44 is rigidly secured to the pivot 45 causing the latter to turn with the move ment of the pedal. The face of 46 engaging with "47 is cam shaped as shown that a partial rotation of the pedal causes the jaws 47 to tightly'clamp the bearing of the foot 43 thus looking it in position. An upward movement of the pedal releases this look and the foot may be adjusted to any new position required.

' When the machine is being transported or stored it'is desirable that it remain in an upright position. For this purpose the foot 49 is provided secured to a portion of the carriage .12 and opposite the foot 43. When the machine is removed from the track this foot occupies the position shown dotted at 49, Fig. 2, forming a horizontal base upon which the machine can rest. When, however, the machine is in use this foot is turned upward so that it does not offer an obstruction when removing the machine from the track and, incidentally, when in this position, it forms a shield for the flywheel 50 of the engine. r

The jaw 61 forming part of the underframe ofthe carriage 12 engages the opposite side of the rail from the drill and takes up the thrust when the atter is in action.

In addition to this I provide a means of clamping the machine in position on the rail when it is being drilled. (Shown in Fig. 5.) This consists of a movable jaw 66 loosely pivoted on shaft 62 and arranged to engage the rail head opposite to jaw 61.. On shaft 62 dog 64: is mounted and rigidly secured by set screw 68. The lower end of this dog has an adjusting screw 65 arranged vto engage a portion of movable jaw 66 so that the normal position of the latterinay. be adjusted with relation to the rail head and thus adjusted for different sizes of rails. The spring 67 is arranged to hold this jaw away from the rail so that the machine is always in position to be removed from the track except when drilling.

This clamp is brought into action by means of the bent handle 63 secured to the shaft 62 at each end. This handle is inclined at an angle and rises upward so that the operator can conveniently manipulate it by hand, the controlling levers for the engine may also be placed on the horizontal portion of this handle; however, there are times when the operator may desire to have one hand free with the machine in operation, I therefore provide the foot pedals 66, 66 connected to this handle by rods 65. 65 thus by keeping pressure on these pedals, the machine is held tightly clamped to the rail.

This machine may be used to drill track from the outside of the rail as shown in the illustrations and it can be used with equal advantage to drill from the inside of the rail simply by turning it around. y

I have in this machine provided means for stabilizing it between the two rails of the track using for this purpose a third roller, Fig. 4 with a shaft connecting to the mecha nism. For instance, in Figs. 3 and 4, if 76 is assumed to be the outline of the opposite rail upon which roller 7 5 is placed and connecting by the pipe shaft 74 to the socket 72, F ig. 2 of the mechanism frame, this will support the machine upon three rollers and upon which it may be rolled along the track. When the opposite rail is on the other side of the machine the shaft 74 is inserted into socket 71, thus supporting the machine in a I slmilar way from the opposite side.

This shaft is readily detachable from the socket for transportation purposes. The sockets are on the center line of the machine, an aperture is provided in 'the lower section 'of the operating handle 81 to preserve this construction.

For certain classes of work it is desirable to drill two holes close together in the rail. For thispurpose I provide the multiple spindle machine shown in the modification Fig. 7 In this case the belt is led over the spindle pulley 21 idler 85 and spindle pulley 21 and a double clutch is provided on the operating handle indicated at 34E and 34 with corresponding clutch rings on each spindle.

I provide a shield for the motor made from angle iron as shown at 81 which is secured to the carriage. To the outer ends of this shield the handle bars 82 are secured, the opposite. ends of these bars being secured to the frame of the machine near the bearing of pulley 19. The horizontal sectionv 83 of these bars is elevated to such an extent that the operator may grip them while standing erect and can roll the machine along the track while in this position. The space between the shield 81 and the motor maybe used for the gasolene tank and magneto incident to the use of a gasolene motor or for the controlling switches necessary for an electric motor. These parts are not shown in the drawing. g

This construction provides a power operated track drill which is comparatively light and can be handled by one man. The position of the motor is so adjusted on the carriage as to balance the mechanism on the rollers; when the machine is moved along the track therefore, practically no effort is needed to balance it on the rollers. The operator stands erect when manipulating the machine and he may turnhis face in either direction along the track, obvi ously hewill turn his face in the direction from which trains are expected. Thus he can stand on either side of the operating handle 31 and operate the pedals thatwill lock the foot48 and also either foot pedal 66 or 66 to clamp the machine to the rail. The handle bars are also conveniently arranged for moving the machine from either side. The mechanism is so arranged as to disengage itself from the rail so that the machine can be quickly moved out of the way of a passing train.

An attachment to the machine consists of the abrasive wheel 88 rigidly secured on the shaft 17 and used for grinding drills at thesame time that the machine is drilling the track.

Having thus described my invention, I
