TRACK-DRILLING DEVICE.
SPECIFICATION forming part of Letters Patent No. 446,023, dated February 10, 1891.
Application filed March 3, 1890. Renewed December 18, 1890. Serial No. 875,140. (No model.)
To aZZ whom it may concern:
Be it known that I, BENJAMIN F. SMITH, a citizen of the United States, and a resident of Somerville,in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Track-Drilling Devices, of which the following, taken in connection with the accompanying drawings, is a specification.
This invention relates to improvements in track-drilling machines for the purpose of drilling rails, girders, &c., and it is carried out as follows, reference being had to the accompanying drawings, wherein- Figure 1 represents a perspective view of the machine, showing it in position for drilling rails. Fig. 2 represents a plan view of the same. Fig. 3 represents-across-section on the line X X shown in Fig. 2. Fig. 4 represents a front view of the adjustable back rest for the drill-stock. Fig. 5 represents a plan view of the adjustable foot-rest for the purpose of supporting the inner end of the frame. Fig. 0 represents a longitudinal section of said rest on the line Y Y shown in Fig. 5, and Fig. 7 represents a cross-section of the same on the line Z Z shown in Fig. 5.
Similar letters refer to similar parts wherever they occur on the different parts of the drawings.
In Figs. 1, 2, and 3, a represents the rail to be drilled, and Z) Z) Z) represent the sleepers of a railroad-track, as usual. The drill-stock supporting frame is preferably composed of three parts-namely, a pair of hooked bars 0 0, having hooked ends 0 0, adapted to bear against the outside of the rail that is to be drilled, and having their inner ends preferably bolted and secured in a detachable manner to the rest-bar D, as shown. In devices of this kind it is essential that the rest-barD should be supported on the sleepers or other portion of the track, and for this purpose I employ a forked clamp or rest-piece E, adapted to receive the bar D, and to be secured to the latter, whenever so desired, by means of a suitable thumb or set screw E.
Through the rear part of the clamp E is made a vertical perforation c, in which is vertically adjustable the tapering rod e, having preferably a foot or enlargement e in its lower end adapted to rest on one of the sleepers or other part of the track during the operation of drilling the rail. The rod 6 is adj ustably secured to the clamp E by means of a thumb or set screw 6 as shown in Figs. 2,
3, 5, and (5. e" is a pin orprojection. at the upper end of the rod e, so as to prevent the latter from getting accidentally detached from the clamp E. By this arrangement the barD can be supported at any desired height from the sleepers, and after being so adjusted the screw is tightened up, so as to bear against the tapering side of the rod 6', thus preventing the clamp E from sagging down on said rod.
On the rest-bar D is adjustably secured, by means of a thumb or set screw f, the back rest F, that serves as a rest for the pointed rear end of the polygonal sleeve G, which is internally screw-threaded for the reception of the feed-screw g on the drill-stock G.
H is the drill, as usual, inserted in the forward end of the drill-holder or drill-stock G. The drill-stock may be of any Well-known construction, with a ring K surrounding it and adapted to swing around said drill-stock, and provided with pawl-and-ratchet or friction-roller devices, as is common in the art, for the purpose of imparting an intermittent 8o rotary motion to the drill during the rocking motion of the lever K, that is secured to the said ring K. The lever K is tubular, and in it is longitudinally adjustable the rod 717, having a handle 7c" in its upper end, as shown in Figs. 1, 2, and 3, by which arrangement the length of the drill-stock handle may easily be adjusted to suit the requirements of the op- Y orator. By means of a thumb or set screw 75" the rod 7a is secured to the tubular lever K, after being adjusted as above described.
The rails to be drilled frequently vary in height, and as it is desirable that the drill and drill-stock should be held horizontally, or nearly so, during the operation of drilling 9 5 the rail I make on the inside of the back rest F a number of parallel grooves f f and an index F, corresponding to said respective grooves, such index being marked'in accordance with the height of the rails for which the device is to be used. Thus, for instance, if a four-inch rail is to be drilled,linsert the conical end of the polygonal sleeve G in the groove f, corresponding to such sized rail,
when the drill will be held in a horizontal, or nearly so, position. This saves a great deal of unnecessary waste of time usually consumed in trying to locate, center, and support the rear end of the drill-stock according to the different heights of rails that are to be drilled.
By making the bar D detachable from the side bars 0 O, I am enabled to easily slip on the bar D the back rest F, and if the latter should get broken or injured a new one can easily be placed on the said bar D.
L is a wrench adapted to fit around a portion of the hexagonal or polygonal sleeve G, as shown inFig. 1, and to be detached therefrom at the will of the operator, and by means of it the operator can temporarily hold the sleeve G stationary, while he turns the drillstock by means of the lever K, thus causing the drill to be fed forward from time to time, as may be required, without interrupting the drilling operation.
After the drill has been fed the desired distance the operator removes the wrench L from the polygonal sleeve and continues to turn the drill by swinging the lever K and its handle 70 forward and back until an additional feed of the drill is needed, when the operator again holds the sleeve G stationary by means of the wrench L, and so on until the rail is drilled through.
What I wish to secure by Letters Patent, and claim, is-
1. In combination with the back bar of a d rill-supportin g frame, the longitudinally-adjustable back rest having a series of longitudinal grooves f f and index F, substantially as and for the purpose set forth.
2. In combination with the back bar of a drill-sup portin g frame, the longitudinally-adjustable clamp E, having a vertical perforation, a tapering foot-rest 6', adjustable in said perforation, and an adjustable fastening device for regulating the position of said footrest relatively to the clamp E, substantially as and for the purpose set forth.
3. The track-drilling device, as described, consisting of the hooked bars 0 C and restbar D, combined with the longitudinally-adjustable back rest F and longitudinally-adj ustable clamp E, having the vertically-adjustable tapering supporting rod 6, and means for securing the same, substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 18th day of January, A. D. 1890.
BENJAMIN F. SMITH.
