CONVERTIBLE DRILL AND WRENCH.

SPECIFICATION forming part of Letters Patent No. 465,626, dated December 22, 1891.

Application filed March 31, 1891. Serial No. 387,145. (No model.)

To aZZ whom it may concern:

Be it known that LJOHN WATERMAN, a citizen of the United States, residing at Villisca, in the county of Montgomery and State of Iowa, have invented certain new and useful Improvements in Convertible Drills and renches and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in convertible drills and wrenches especially adapted for use in drilling railway-rails and loosening or tightening bolt-nuts or taps on the rails.

The object of my invention is to provide a simple and compact machine for drilling railway-rails, which machine can be readily changed to adapt it for loosening or tightening nuts on the rails.

With these ends in view my invention consists of a single upright or standard suitably pivoted in one end of ahorizontal main frame, a shaft extending vertically through the cen ter of said standard, which shaft is provided with a crank and handles on its upper end and a gear-wheel on its lower end. Secured in the main frame and projecting therefrom is a drill-stock, which is provided with a gearwheel which meshes with the gear-wheel on the upright-shaft, and in the other end of the main frame is a supplemental frame,in which is secureda feed-screw which operates to feed the drill forward and keep it in position for operating properly. On the lower end of the upright shaft, above the gear-wheel thereon, is an eccentric disk which engages with a lever, and this lever has two pawls on its end to engage with ratchet-wheels on the feedscrew, by means of which the said feed-screw is revolved and the drill advanced or returned. Pivoted on the forward part of the upright is a bifurcated holding-arm which insures a good contact with the rail and holds the machine steady. To further hold the upright in a firm position, I provide a foldable brace,

one end of which is fastened to the upright and the other end to the rear end of the main frame. Pivotally secured on the rear end of the main frame is a rest which has its basepiece projecting at either end to form handles for carrying the machine or steps to hold it steadily in position with the feet, as described.

My invention further consists in providing two arms or hooks on the front of the frame instead of the single bifurcated arm and pivoting the same to bars secured in guides or keepers on either side of the main frame. The foldable brace is also provided with a bifurcated lower portion, and these bifurcated arms are pivotally secured in the rear end of the frame. The extreme ends of these arms are bent upwardly and loosely secured to the rods, so that when the brace is bent and the standard lowered the ends of the bifurcated arms will move the side rods lengthwise and thus loosen the holding-arms on the rail.

My invention further consists of the peculiar construction and arrangement of parts, as will more fully appear hereinafter.

To enable others to understand my invention, I have illustrated the same in the accompanying drawings, in which Figure I is a side elevation of my improved machine, partly broken away, to show the working mechanism. Fig. II is a view show ing the upright in a folded position and the drill-stock provided with a wrench for use in tightening or loosening bolts. Fig.'III is a rear view of my machine. Fig. IV is a sectional elevation taken on the line 00 a; of Fig. III. Figs. Vand VI are elevations showing modified constructions of my invention.

Referring to the drawings, in which like numerals of reference denote corresponding parts in all the figures, l. designates the upright or standard, which is preferably made of wood, and is mounted on a plate 2, having the downwardly-extending ends 3 3,an.d this upright is braced by rods 4 l, secured to the plate 2 and the upright on either side of the latter. Extending through the center of the upright is a shaft 5, which'has gear-wheels 6 7 on either end thereof. The upper gear 6 meshes with another gear-wheel 8 on a shaft 9, which is journaled in bearings in the upwardly-projecting ends of the plate 10, secured on the top of the upright 1. The shaft 9 is provided with suitable cranks 11, and when these are turned the shaft 5 is revolved.

Fitted on this shaft 5, just above the gear 1 is a cam 12, which revolves with the shaft, for a purpose hereinafter described. The downwardly-extending ends 3 3 of the plate 2 are secured to short metallic strips 12 12, which extend at right angles to the ends 3 3,and are secured to the sides of the main frame 13 about the center thereof. Suitably mounted in this frame is a drill-stock 14:, which projects beyond the front of the frame, and is adapted to receive a drill or wrench, as desired. This drill-stock is provided with a gear-wheel 15 just inside the frame 13,which meshes with the gear 7, and by means of which the drill is operated. The strips 12 12 are of such length that when the upright is in a vertical position the gears and 7 will be brought into a proper engagement, and in order to provide a firm base for the upright I arrange an upwardly-extending plate 16 on the front of the frame 13, upon which a small projecting plate 17 on the upright 1 is arranged to rest. This main frame 13 is provided with a resting-plate 18 on the forward end thereof and another base-plate 19 on the rear end of the frame which has the projecting standards 20 pivoted on a shaft 21. By means of this pivoted plate I provide a suitable base for the machine when it is in operation, and when it is desired to move the same this base can be turnedup over the end of the frame and the projecting ends will then form handles by which the machine can be carried.

Secured to the shaft 21 is a foldable bracerod 22, which is connected to the upper portion of the upright, and it is provided with a handle at the juncture of the two members thereof. When the upright 1 is thrown down, the rod 22 is drawn out and the handle thereon rests on the ground and supports the upright.

In the rear of the main frame is a supplemental frame 23, in which is secured a feedscrew 24, which bears against or engages with the drill-stock and feeds it forward to make the drill work properly. This feed-screw is provided with two ratchet-wheels 25 25,which have reversely-inclined teeth and arranged to operate between the piece 26 and the U- shaped supplemental frame 23.

Secured on one side of the main frame is a lever 27, which is operated by the cam-disk 12, and is provided with a pawl 28 on its upturned end and another pawl 29 on the other projecting end thereof. The pawl 28 is arranged to engage with the ratchet-wheel 25 and push the same around as the cam 12 presses the lever 27 out, thus feeding the drillstock forward and causing the drill to contact properly with the work on which it is operating.

As heretofore mentioned, I have adapted my invention to be used for tightening or loosening nuts on railways or other structures, and it is therefore necessary to provide a machine which will work equally satisfactory in both directions. With this end in view I have provided the hook-shaped pawl 29 to engage with the reversely-inclined teeth on the ratchet-wheel 25, andwhich. serves to rotate the feed-screw in the reverse direction when the handles 11 are turned backward. Thus the wrench 30 can be revolved forward or backward by simply reversing the movement of the handles 11, the gears 15 and 7 revolved in a reverse direction, and the pawl on the lever 27 engages with its ratchet-wheel, and by this means the wrench is revolved and fed backward, the other pawl simply sliding over the teeth on its ratchet-wheel and being adapted to engage with its ratchet-wheel to reverse. the wrench when the handles are turned in an opposite direction. This con struction and arrangement of a drill and wrench in one machine will be appreciated by those skilled in the art, as by using my machine much time will be saved and extra mechanism avoided. After the hole has been properly drilled thedrilling-bit can be quickly removed and a wrench substituted therefor,

and the nut may be then screwed on the bolt without loss of time.

To insure better connection between the machine and a railroad-rail, on which the machine is generally used, I provide a bifurcated holding-arm 31, which is pivotally secured to the front of the upright 1, said arm 31 having'the hooks 32 33, adapted to engage with a rail and hold the machine firm and steady. The bifurcated arm 31, having two hooks, is preferred to a single arm and hook and to two separate arms and hooks, as by this device the two books prevent the machine from moving sid'ewise, and the single pivoted arm on the upright permits it to be folded on the upright for convenience in carrying the machine.

34 35 are suitable handles secured on the upright l for use in moving the machine.

The operation of my machine will be readily understood from the foregoing description, as it is only necessary to adjust the drill and bifurcated arm on the rail and operate the cranks 11. After drilling the hole, if it is desired to screw anut on a belt which has been inserted in the hole a wrench is substituted for the drill, as shown, and the machine is then operated as before. hen it is desired to remove a nut from a bolt, the cranks are simply turned in a reverse direction and the wrench will unscrew the nut.

In Figs. V and VI, I have shown a modified construction, which consists, principally, in providing two arms or hooks 32' 33" suitably joined together, and these arms extend on either side of the main frame and are loosely secured to bars or rods 36, which are secured in place by guides or keepers 31' midway of the frame. I also bifurcate the lower portion of the foldable brace-rod 22, and the lower ends 22' are bent outwardly and pivotally secured at said curved portions 37 to either side of the rearend of the main frame, and the projecting ends are also loosely connected with the rear ends of the side rods 36. This IIO latter construction is very simple and possesses practical advantages, as it will be read ily seen that when the upright is turned down the brace will break back and the curved ends thereof willthrow the side bars 36 for ward, and therebyloosen the grip of the arms and hooks on the rail; and, again, when the arms and hooks have been placed in position on a rail, the nprightremainin g in a horizontal position, when the upright is turned to a verti-- cal position it will cause the arms and hooks to grasp the rail firmly and assume a rigid and 1 substantial position, thus facilitating the adjustment of the machine to the rail. I have also shown the upright l constructed partly of wood, and the lower portion thereof consisting of two pieces of iron 38, suitably fastened to the wooden upper end and the plate 2. This is a neater construction and affords a better opportunity for attending to the working mechanism of the machine.

I am aware that changes in the form and proportion of parts can be made without departing from the spirit or sacrificing the advantages of my invention, and I therefore reserve the right to make such changes as fall within the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
