a citizen of the United States, and a resident of the city ofR-ochester, in the county of Monroe and State of New York, have in vented a new and useful Power Rail-Drill, of which the following is a specification.

This invention relates to a power rail drill. a

The primary object of this form and construction that it may be readily moved by one man along the line of rails in which it is desired to drill holes. 1

Other objects and advantages will appear as the description of the invention progresses, and the novel features of the invention will be particularly pointed out in the appended claims.

In describing the invention in detail, reference is had to the accompanying drawings, wherein I have illustrateda preferred physical embodiment of my invention, and wherein like characters of reference designate corresponding parts throughout the several views, and in which:

Figure 1, is a perspective view of my power rail drill in position upon a rail with device, and'the support for the main driving shaft and driving shaft removed to more clearly show the parts; Fig. 2, is a side elevation of my power rail drill with certain parts in section to more clearly show detail of a cam arrangement for manipulating the feeding used in my power drill; Fig. 4:, is a detail view showing thev manner of operating the feed forthe drill used in my power drill.

1, designates a rail, such as the rail of a which it is desired tobore holes for the purpose of inserting the ends of bond wires so as to render the line of rails electrically continuous at places such frogs, and switches.

as joints, crossings,

has a main frame which My power drill serves not only to position and support themechanism and connections for oper-' the drill when actually engaged in hole in a rail, but also serves as a power atlng means for easily movingthe entire mechanism froin'polnt to point along the rail upon'which work 1s being performed. Thls main invention is the production of a power rail drlll of such the construction; Fig. 8, is a mechanism for the drill frame consists of two side rails 3 and 4, each of which has a depending shoulder as 5, which, when the parts are in a position for drilling a hole a in a rail, are positioned firmly agalnst the gage F side of the rail. The side rails 3 and 1 are joined at one end by the bar 6,. which is extended forwardly ofthe side rail 4: and bent inwardly so as to be positioned conveniently to'form a ban 7 dle as 7. Fastened securely to the side rail 3 and extending rearwardly thereof are spaced arms 8 and 9 which by'means of a shaft 10 support the wheel 2 which has flanges on both sides, which flanges arev has the handle 14 secured to one end and this handle is so positioned that it lies a proper distance from the handle 7 so as to serve, together with the handle 7, as what mlght be termed the two handles of a wheelbarrow, the wheel of which would be 2, so

that the operator of the power drill when desiring to move it from place to place would do so by grasping handles 7 and 1 1 and lifting thereon so as-toraise all parts to a convenient position so that-he could then'easily push the whole device forward or pull it rearwardly, for, as inthe ordinary wheelbarrow, the greater portion of the placed a distance apart sufficient to allow weight would be supported by the wheel 21 Although the particular means and mechanisms for actually operating the drill during the process ofboring the rail form no part of applicants invention, nevertheless, an acceptable formof such means hasi been herein shown so as 'to morefully show the connection between the handle '14. and

in applicants device one phase of the in-- .vention resides in the fact that one of the serves asa means for quickly Withdrawing the drill from operative position and also to the means for actually drilling the rail, as

quickly place the drill "approximately in operative position. 1 a

The means for supplying powerinaybe any of the ordinary and well known means suitable for, the purpose and applicanthas herein 'shownfan internal combustion engine 15, as an example of such means. As applicant'has shown an internalcombustion en gine 15, and as such engines generally re quire to be manually started, a means for starting such engine is also shown which consists of acrank 25 attached to shaft 26 which is movable longitudinally in the bearing 27 and which bears at its inner end half of a clutch member 28 which is adapted to engage with half clutch member 29 attached rigidly to shaft 18 when the shaft 26 is moved longitudinally to the left as viewed in Fig. 2, so that by a movement thereafter of the crank 25 in a clockwise direction the shaft 18 and gear wheel 17 and 16 are caused to turn so as to actuate the internal mechanism of the internal combustion engine 15 and so give it an initial movement necessary to cause it to start. This power means is connected to the drill by means of gear 16, which meshes with gear 17, rigidly. fastened to shaft 18. The shaft 18 is journaled in the bearings 19 and 20 and bears driving pulley 21, which, by suitable means as a belt 22 drives a pulley 23, which is rigidly attached to drill spindle 24. The drill spindle 24 is supported by a bearing 30: and by the long sleeve 31, and has a drill as 32 properly secured in one end and is spring pressed in one direction by the spring 33 hearing at one end against the bearing 30 and at the other end against the head 34 attached to the outer end of the spindle 24.

In order to cause the drill to feed forward when in operation, sleeve 31 has teeth 35 out in its upper surface and is mounted so as to move freely longitudinally in the hearing 36 formed in the cross piece 37. The teeth 35 are engaged by pinion 38 on a shaft 39, which shaft also carries a worm wheel 40 which meshes with a worm 41. This worm 41 has on one end the pulley 42 which is driven by means of belt 43 from the pulley 44 attached to shaft 18, so that a rotation )f shaft 18 causes a rotation of worm 41, worm wheel 40, shaft 39, and gear wheel 38, and, consequently, a forward movement of sleeve 31, which, abutting against the shoulder 45 of drill spindle 24, causes the drill spindle to move toward the rail, thereby causing the drill 32 to be advanced as the drilling progresses.

In order to provide for a rapid movement in either direction of the drill spindle 24, means have been provided to disengage the worm 41 from the worm wheel 40 so that the drill spindle together with the drill may be moved in one direction rapidly by the spring 33 or may be moved in the other direction by manually pushing against the member 34. This means for disengaging worm 41:, consists of the members 46 and 47 in which the worm is journaled eccentrically so that a rotation of the members 46 and 47 in one direction causes worm 41 to be raised from engagement with worm wheel 40 and a movement of the members 46 and 47 in another direction causes an engagement of worm 41 with worm wheel 40. The means for moving the members 46 and 47 is the handle 48 which is attached to a bar 49 having spaced ends 50 and 51 extending at right angles to it. Pins 52 secure the members 46 and 47 and the ends 51 and 50 together respectively so that a movement up or down of the handle 48 causes the members 46 and 47 to turn upon themselves and so raise or lower the worm 41.

The drill spindle 24', the sleeve 31, and the feeding mechanism including the worm 41, having the pulley 42, are journaled in and supported by cross pieces 37 and 53 which. cross pieces form with members 54, 55 and 56 and 57 a carriage held between the side rails 3 and 4 and slidable thereon. The carriage is moved bodily with all of its supported parts by means. of links 58 which at one end are connected to the carriage and to the other end are connected with the crank arms 59, so that a movement of the shaft 13 by means of handle 14 causes a movement of the carriage upon which the drill spindle 24, sleeve 31 and the feed mechanism are supported.

In order that the drill shall be brought to the proper position in relation to the rail and in order that the carriage supporting the feed mechanism shall be held from movement during the operation of drilling, applicant has provided a wedging device which is intended to be forced tightly between the under side of the ball of the rail and the top side of the flange of the rail. This wedging device consists of the upper and lower beveled members 60, each pivoted by pins 61 to arm 62 which is rigidly fastened by means of member 64 to the carriage. The distance between the members may be varied by means of the right and left hand threaded. member 63 so as to provide for the variations in different rails.

The handle 14 when moved to the position in which it should be placed for drilling, is supported by the bracket 65 which is so placed that the shaft 13 is revolved to a position such that the line of action through the pins in the ends of the links 58passes through the center of the shaft 13 and at the same time beveled members 60 are pressed firmly against the surface with which they should contact, so that the carriage carrying the feed mechanism for the drill is held perfectly rigid.

As is well known to those skilled in the railway art all devices for use upon the rails of an operating railway which in use project over or upon the ball of the rail, must be of such a nature that they can be removed with the greatest of rapidity, because at any moment a train is liable to approach at an extremely high speed affording in some cases an almost infinitesimal amount ing member 60, so that the shoulders may be freed from the gage side of the rail andthe whole device, if necessary, overturned in a direction away from the rail, using the wheel 2 as a pivot. .The virtue of employ-f ing handle 14 both for transporting the power drill as a whole and also for quicklyfreeing the device from the rail, will be readily seen when it is realized that the natural position for one operating the drill would be in front of the same with one hand grasping the handle 7 and the other hand grasping the handle l l so as to be in a position to quickly retract the drill when the hole in the rail has been completely bored and to move on tothenext position for drilling. Furthermore, an alert operator would, during the drilling operation, al-. ways have his hand upon the handle lt so as to quickly withdraw the drill from its hole if any unforeseen difficulty is experienced I in drilling. In short,the ordinary operation of the power drill causes the operator to be in proper position and to have hold of the proper parts so as to instantly disengage the device from the rail and remove it from the rail.

Although I have particularly described the construction of one physical embodiment of my invention, and explained the operation and principle thereof; nevertheless, I desire to have it understood that the form selected is merely illustrative, but does not exhaust the possible physical embodiments of the idea of means underlying my invention. What I claim as new and desire to secure by Letters Patent of the United States, is: 1.
