Description

UNITED STATES PATENT OFFICE.
AUGUSTIJOEHNER, OF ST. LOUIS, MISSOURI, ASSIGNOR TO ST. LOUIS POLYTEOHNIO IRON WORKS, OF SAMEPLAGE.
SPECIFICATION formingpart of Letters Patent No. 237,400, dated February 8, 1881.
Application filedJuly 20, 1880. (No model.)
pertains to make and use the same, referencebeing had to the accompanying drawings, and
to the letters of reference thereon, which form a part of this specification.
The object of the invention is to furnish a device for drilling holes in railway-rails, either when such rails are disconnected or fixed in position on the sleepers, the apparatus being so constructed that the drilling is effected easilyand with accuracy. The frame of the apparatus also remains firm and steady in place after the hole is bored. The point of the drill is saved from breakage when it has passed through the rail, and the several parts of the apparatus may be readily detached and renewed when broken or worn out by long use.
In the drawings referred to, Figure lrepresents my improved drilling apparatus in a horizontal position and applied to a railwayrail fixed in place. Fig. 2 is anend View of the apparatus. Fig. 3 shows, in plan, the center-piece on the frame. Fig. 4 illustrates the center-piece in vertical section. Figs. 5 and 6 represent detached views of certain details of the apparatus.
Referring to the drawings, A designates a tubular bar, the extremities of which are th readed to receive the shoes B, which are also threaded, so that they may be screwed on the ends of said bar and detached therefrom, the said shoes being, preferably, of malleable iron and of the form shown. Each of the shoes B is provided with an opening, b, to receive one end of one of the curved bars 0, the end of the bar being passed into the shoe and secured thereto by a bolt, a. On the other end of each of the bars O a hook, at, is forged to hook onto the flange or base of the rail. (See Fig. 2.) On each of the bars 0 slides a thumb-clutch, E, which is pushed against the flange of the rail when the bar is hooked thereto, and is fastened in place by means of a screw, 6. The
clutch is formedto answer for a rail witha base ofany size.
D indicates a center-piece, which slides on i the tubular bar A, passing through it, said center-piece having a socket to receive one end ofthe driILfeedingscrew M. The center-piece Dis secured to bar A at any desired point by means of a screw, d, and a tightening steel plate, s, said plate being placed in a cavity in the center-piece, and being pressed against the bar by turning the screw. The bearingsurface of plate 8 may be serrated for the purpose of fastening firmly.
G is a housing formed on the-centerpiece D, within which housingis a catch'bolt, e, the latter being pressed by a spring, f, to the teeth It on the wheel K ofthe drill-propelling screw.
It will be seen from the construction ofthe catch-bolt e and the, teeth h that the wheel K is prevented by the catch-bolt from turning in one direction, but may be easily turned in the opposite direction, the bolt 0 passing over the teeth h as the wheel is turned. The said bolt may be raised and fastened from the teeth by means of a thumb-screw, 0, passing into the bolt through a slot in the housing. A number of holes, 9, in the periphery of wheel K are provided for the reception of a small hand-lever for turning the wheel, so that the machine can be used as a self-feeder or as; a hand-feeder.
L is the ratchet-lever with which to operate thedrill I.
. The bar A is made circular in transverse section and passes ,through a corresponding aperture in the center-piece, so that when the apparatus is secured to a fixed rail in a horizontal position the center-piece may be turned over and reversed in position on bar A, so that a hole may be drilled in the opposite rail without changing the position of the frame of the apparatus, a longer drill being used. Also, as will be seen, the center-piece may be set and adjusted on bar A at various inclinations for drilling in various directions, the apparatus being usedin either a vertical or a horizontal position, as occasion may require. To counteract the tension or yielding of the bar A in operation, a flat bar, H, is inserted therein, said bar being of about the same length of bar A and acting as a resisting spring-bar,
The operation is as follows Place the frame of the apparatus so that the hooked bars 0 are about equidistant from a junction of two rails; shove the bars 0 under the rail, and draw the hooks to on the base of the rail; close the thumb-clutches E on the base, and wrench the set-screws 1', so that the frame of the apparatus will be firmly attached to the rail. The center-piece is then moved on bar A to a point opposite the point in the rail where a hole is to be drilled, and secured in place by means of the screw (1. The drill, ratchet-lever, and screw-spindle being in position, the upper end of the spindle entering the socket in the cen;
fer-piece, the spring catch-bolt c is loosened by a turn of thumb-screw, and engages with the teeth on wheel K, so as to prevent the screw-spindle from turning then each movement forward of the ratchet-lever moves the drill-cylinder on the screw, thus lengthening the screw-spindle and feeding the drill. In the opposite movement the catch-bolt e readily travels over the teeth It, bearing against the inclined sides of the same. The catch-bolt may be raised from teeth h and made fast in the housing by the thumb-screw, and then a hand-lever may be used in connection with wheel K, thus forming a hand feed-drill. To drill a hole in the opposite rail it is not necessary to detach the frame, but simply loosen the screw 01 on center-piece D and turn the center-piece over toward the opposite rail, fasten the same, and substitute a longer drill in the cylinder.
frame of the apparatus are readily attached and adjusted, and are held firmly together dur in g operation. The parts may also be quickly detached and placed together within a small space for the purpose of transportation.
I claim- 1. In a drilling apparatus, the tubular bar A, provided with the detachable shoes B, the latter being formed to receive and hold the hook-bars O, substantially as shown, for the purposes set forth.
2. The cylindrical tubular bar A of the drillin g apparatus, having therein the flat resistingbar H, and provided with shoes B, in combination with the hook-bars 0, having thethumbclutches, substantially as set forth.
3. In the drilling apparatus, the round tubular bar A, in combination with the cen ter-piece D, sliding thereon, and provided with the screw 61 and plate 8, as and for the purposes described.
4. In a drilling apparatus,- the adjustable center-piece D, supporting the drill-spindle, provided with the housing G, containing the adjustable spring catch-bolt, to connect, as shown, with the teeth h of wheel K on the drill-feeding screw, substantially as and forthe purposes set forth.
