CALD- WELL, residing atGalaX, in the State of Vii": ginia, citizens of the United States, have ing ventedcertain new and useful Improvements 3 in Railway-Track Machines; and .we do declare thefollowing to be a full, clear, and exand connected byacross-bar 1-2, which rests] upon the ties 1. 1 On the side barsv 6 of the stationary frame g is slidably'mounteda movable frame 13, con- This invention relates to improvements in 1 sisting of longitudinallydisposedside? bars railway-track machines;

ingly engage or rest on thesidebarsfi: of the stationary frame; The longitudinal bars 14 adjacent to theouter cross-bar 16 are turned up at right angles, as at 17, and are connect ed together at their upper and lower ends by cross-bars 18 thereby forming, an upright frame 19. The uprig'htframe 19 is further braced by inclined brace-bars 21, which are connected at their upper, ends to the top of I :saidframe and at their lower. ends to the forwardends 1 of the longitudinal barsl4: To the under ,side'of the'longitudinal bars-14, be-

neath thecross-bar 15, is secured. a cross-bar 22, in which is journaled the front; section 23 of flexibleshaft 24. On the forward end; of said shaft-section23 formed a wrench-head 25, which is adapted to engage the nutfiof the track-rail, said head having formed therein a recess 25 to receivea drill and -a,- se tscrew25 tohold the drill in place. To the rear end of the vshaft-section23is connected one end of; a universal joint, 6,f;and to'-tl1 e rear end of said joint is connected ther'ear .section;2.;7 of saidshaft 24, the rear portion; of saidsection being threaded, asiat 28. The shaft-section 27 is journal ed 1n the cross-bars 16ofthe movable frame 13,;and. on said sec- ;tion between the bars 16 isfi-Xedly mounted ;a vertically disposed bevel gear wheel; 29, which is in mesh with and is drivenby bevel gear pinion 30, fixedona vertically-disposed shaft 31., which is mounted in bearings- 32, secured to ,theupright frame 19. The upper end of the shaft 31 is bent, tofornr acrankhandle 33, by whichsaid shaft and gear-pinion maybe turned, thereby turning the gearwheel 43 and sleeve 42.

wheel 29, flexible shaft 24, and wrench-head 25, which when engaged with a nut will screw the same on or off a bolt.

On the cross-bar 12 is slidably mounted a pair of horizontally-disposed clamping-bars 34, between which is adapted to be clamped a two-part nut 35. The parts of said nut are adapted to be brought into engagement with the threaded end of the shaft 28, so that when said shaft is driven, as hereinbefore described, the sliding frame 13 will be moved on the stationary frame, thereby keeping the wrench-head in engagement with the nut.

The bars 34 may be slidingly Connected to the cross-bar 12 in any suitable manner, but are preferably provided near their opposite ends with alined slots 36, through which are adapted to pass bolts 37, thus slidably securing the bars in place. In one'end of the bars 34 are formed alined slots 38, in which are disposed the ends of oppositely-projecting cam-lugs 39, which are fixed on a pivotallymounted shaft 40, journaled on the bar 12, and to said shaft is connected an operatinglever 41, whereby the shaft and the lugs 39 are turned. The oppositely-projecting lugs engaging the upper and lower bars through the slots 38 will shift one of the same in one direction and the other in the opposite direction, thus separating the sections of the nut, one of said nut-sections being attached to one of the bars and the other section to the other bar. When the nut 35 has thus been separated, the sliding frame may be moved back on the stationary frame, thereby disengaging the wrench-head from the nut on the rail.

In Figs. 4, 5, and 6 of the drawings the machine is shown as arranged for a drill. In this instance an exteriorly-threaded sleeve 42 is arranged on the shaft 28, and on the inner end of said sleeve is mounted a ratchet-wheel 43. Pivotally mounted on the frame 19 is a bellcrank lever 44, to the short arm of which is pivotally connected a gravity-pawl 45, said pawl being adapted to engage the teeth of the wheel 43. The long arm of the bellcrank lever projects forwardly in position to be engaged by a cam 46, arranged on the side of the beveled gear-Wheel 29, whereby when said wheel is turned the cam will trip the bellcrank lever and cause the same to actuate the pawl 45, which will turn the ratchet- When the machine is arranged as a drill, a sectional nut 35 of the proper size to engage the threaded sleeve 42 will be' arranged in the bars 34, so that when said sleeve is turned, as hereinbefore described, the movable frame 13 will be gradually shifted thereby to feed the drill forward while boring a hole. It will be understood that when the machine is being used as a drill the feeding of the frame 13 as pro duced by the engagement of the nut with the shaft 24 would be too rapid. Consequently the above-described feedim mechanism is used to properly feed the drill.

In Fig. 7 of the drawings is shown a modified form of the operatin mechanism. In this instance the verticalI -disposed drive shaft 31 is provided on its upper end with a beveled gear-wheel 47, with which is adapted to mesh a bevel gear-wheel 48, mounted on a horizontally-disposed shaft 49, j ournaled in the upper end of the frame 19. On each end of the shaft 49 is secured a crank 50, thereby permitting the machine to be operated by two persons.

In order that the movable frame 13 may be quickly adjusted to engage and disengage the wrench-head with and from a nut, a lever 51 is pivotally mounted on the cross-bar 10, and to said lever is pivotally connected one end of a link 52, the opposite end of which is connected to the cross-bar 15 of the movable frame 13, whereby upon releasing the threaded end of the shaft 24 and operating said lever said movable frame may be adjusted back and forth on said stationary frame to bring the former to the desired position.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
