-a rail 76.
A stud 69 is fixed at the center of the cross frame member 32-4l0-5(l, and the lever 70 is pivoted in this stud by means of the pin 72.. The spring 75, acting between the v member 50 and one end of the lever 70, keeps the opposite end thereof 71 resting on the cam a9. At the same end of the lever 70 with the spring 7 5 is pivoted the pawl 73 by means of the screw 74.-. This pawl 73 engages the ratchet wheel 56.
ln the drawings the handle 19 and the cam 20 are shown in the position which they would occupy when the machine is engaging machine the handle 19 can be thrown around about 180 degrees, thus pushinf back the jaws 28 so that the machine can be removed from the rail. The action just described is due to the turning of the cam 20 in the elliptical hole 27 in the plate 26 which unitesthe jaws 28. Since the pawls 67 are disposed oppositely, it followsthat oscillation of the prev dffom accidentally drop Jing off by `means of the hook end 7l of the ever 70 1n combination with the flange t6 adjacent to the cam 1&9.
The frame member 32-40-50 rests on the side plates 16,'the studs 33 being adapted to slide back and forth in the slots 3l. By rotating 'the handle 63 by hand the 'shaft- 57-59 will be caused to rotate, and thus, by reason of the screw threaded engagement with the projection 50, the frame32-4e0-5O and the parts carried thereby will be moved forward or backward as desired. Tn case it is wished to withdraw the drill, that is to move the frame 3.240--50 backward, it will be necessary to rotate the shaft 57-59 so that the ratchet wheel 56 will turn against the pawl 73'. Therefore the awl 73 must be thrown over to the right.1 hen the shaft 57-59 is rotated byhand, as just described, the sleeve 5s will rotate therewith, the screws 78 revolving the ring segments in the annular groove 52. The spring acts to press the end 7l of the lever 70 on the cam 4&9. Thus the rotation of the drill 4:7 oscillates the lever 70 causing the pawl 73 to slowly rotate the ratchet wheel 56 step by step. Inasmuch as the ratchet wheel 5G is a partof the sleeve 54, it follows that the pin 55, by reason of its engagement with the slot 53 in the threaded shaft 57, will cause the When it is desired to move the sean-ee shaft 57 to "otate, thus automatically feedin rails while the latter are in place on the ground. By means of the handle 19 and cam' 20 the device can be instantly applied to a' rail or removed therefrom. The machine permits the operator to assume a convenient posture and to apply his strength most directly and effectively to work the machine. The drill operates on both back 'and forth strokes by the handle 68, thus being more effective and economical of effort than drills which work only one way. The drill can be quickly fed forward or Withdrawn from the work by means of the handle 63 operated manually. But a simple and effective automatic feed is provided in the cam 49, lever 70 and associated parts.

4f. Tn combination, a main frame, a cross frame, the ends of two opposite arms thereof having sliding engagements with the main frame, a drill socket having a thrust bearing on a third arm of the cross, and feeding mechanism acting between the fourth arm ofthe cross and the main frame.
Tn combination, a yoke-shaped frame having opposite parallel slots, a cross-shaped frame member with the ends of two opposite arms in said slots,a drill socket, a thrust bearing between the same and the third arm of the cross, and feeding mechanism acting between the main frame and the fourth arm of the cross.
6. Tn a track drill, a main frame, a hooked j aw having sliding engagement with the end of the frame, means to reciprocate said jaw an extension from seid jaw at one side of transversely elongated opening, a eem pivadapted to lie .beside a lheed rail with its guide slots therein, e rigid cross shaped slidvrelatively to the frame, e drillfeoeket mount drill the T-rail, said extension having'a sliding engagement with the said mein frame, end a cam carried by one of said members, the other member having a transversely elongated slot in engagement with said eam. Y
. 9. In a'traek drill,a main freine, a jaw having a plate thereon and slidably mounted 1n said man1 reme,sa1d plate having a oted in Asaid man1 freine and within said elongated opening7 and e handle to rotate said cem. y
l0. 'In combi-nation, a yoke-sheped frame arms extendin toward the same and havin.' 7 '1 ing frame with the ends of tvvo opposite arms thereof adapted to slide along the .slots 1n the ernls of the yoke-shaped trainee drill shaft mounted to rotate upon a third-arm of the cross shaped frame, and feeding mechanisin adapted to aotbetween the remaining' arm ofthe cross shaped t' ameand/the ver-v tex of the yoke shaped frame.
ll. ln combination, a yoke-shapedfi'ame adapted 'to lie beside a T-h'ead rail with its arms. extending toward the same, a member having elidin yoke-shaped trame, a hook adapted -to eX- tend from Said last named member to engage the T-head rail, and a cam adapted vto act. between said yoke-shaped frame and said hook to clamp said fram-e in operative position beside the rail.
12. In combination, adapted to lie beside e T-head rail with its arms extending toward the same, a bearing member joining the ends of the yoke-frame, a member adapted to slide between the arms if the yoke-frame, a hook on said member dapted to engage the heed of the rail, and a cam rotetebly mounted in said ,bearing member, said sliding member having a transverse slot adapted to be engaged by said cam.
in testimony whereof, have subseribed my name. f
