RAIL DRILL.
Application filed November 21, 1921. Serial No. 516,651.
To all whom it may concern: rails forming a trackway and 2 indicates Be it known that we, CARL F.

The lever 14 is pivoted to a link 15, one end of which is in turn pivotally connected to the frame 6, the lever 1 1 and the link 15 having a plurality of openings 16 and 17 respectively, so that said parts may be adjusted with respect to each other for obtaining different movements of the motor and bit carried thereby.
In some instances a supporting foot 18 may be pivoted to the frame 6, and this foot may be used for elevating the frame for bringing the bit to a true horizontal position, or if preferred the frame 6 may end at the point of pivotal connection of the foot with the frame, in which event the foot will be used for supporting one end of the frame.
The present form of drill is substantially a one man drill and while it will perform the same functions as a heavier construction the entire weight thereof is such that one man can readily apply it to use or lift it from off the track, and if desired the end of the frame farthest from the bifurcated end may be swung upwardly until the opposite end slips from off its respective rail so that the entire structure may be rested upon the downwardly extending ends 11, and dragged over the ground similar to a sled, although the weight of the device is such that it may be readily carried.
The elevation of the bit may also be readily controlled by loosening the nuts 9 on the threaded ends of the straps 7 and the motor given a slight rotating motion, the connection between the lever 14 and link 15 being such that a certain amount of movement of the motor may be effected without interrupting the operation of the lever.
It will also be seen that by providing the adjustable pivot points between the lever and link, motors and bits of varying lengths maybe accommodated, and also added or decreased pressure applied against the motor casing for feeding the bit forwardly while in operation.
Having thus fully described our said invention, what we claim as new and desire to secure by Letters Patent, is:
1. A rail drill comprising a frame for engagement with the rails said frame carrying U-shaped suporting means, a motor drill having a circular casing with the drill mounted eccentrioally thereof said casing suported by the U-shaped supporting means whereby a rotary adjustment of the casing in the straps adjusts the drill longitudinally and vertically of the rail web, substantially as set forth.
2. A motor drill comprising a frame for engagement with the rails, a motor drill supported beneath the frame the drill being eccentrioally mounted relative to the motor axis, a link pivoted on the frame, a lever for feeding the drill said lever being pivoted to the link and engaging the motor drill in line with the axis of the drill, substantially as set forth.
3. A motor drill comprising a frame for engagement with the rails, a drill supported beneath the frame, means for preventing movement of the frame in either direction across the rail, a supporting foot pivoted to the frame for elevating the frame said foot being of such a length whereby in vertical position it will extend below the bottom of the rail, substantially as set forth.
In Witness whereof, we have hereunto set our hands and seals at Indianapolis, Indiana, this 17th day of November, A. D. nineteen hundred and twenty-one.
