To all whom it may concern:
Be it known that I, WILLIAM L. SMITH, a citizen of the United States, residing at C- lumbus, in the county of Franklin and State of Ohio, have invented certain new and use l'nl Improvements in Rock-Drills, of which the tollowing is a specification, reference being had therein to the accompanying drawmg. I
My invention relates to carriages or gadders" for rock drills, and consists in the novel features and combinations hereinafter described and set forth in the accompanying claims. o.
. In the drawings :Figure 1 is a side elevation of my improved gadder, parts being shown in section; Fig. 2 is a front elevation of the same; Fig. 3 1s a section on theline llllll of Fig. 1; and Fig. 4 is a rear elevation of a portion of the elevating screw boot, looking in the direction of the arrow IV, in Fig. 1. v
1 the truck of the gadder, provided with suitable Wheels 2 and setting spikes3, which spikes may be held elevated byany suitable means, as set screws 4. I
Pivotally connected to the front of the truck, as at 5, is a standard 6, com rising side members 7 having ways 8, pre erably under cut as shown at 9, in Fig. 3, to slidingly support and secure a carriage 10,'having two saddles 11, 11, to receive and clamp the drill bases (not shown). The carriage may be quickly and securely clamped on the ways by means of a Wedge 12, tightened by a capstan-headed screw 13. By this arrangement, two drills may be worked si1nultaneously, if a row or rows vof holes parallel. to the standard are to be drilled.
The carriage is adjusted on the ways by means of a chain 14, secured thereto-as at 15, said chain passing over a sheave 16, journaled at the top of the standard and returning to a winch 17 operated by a worm wheel 18 and Worm 19, the latter being rotated by a hand wheel 20, located on the inner or rear face of the standard.
Thestandard 6' is adjusted by means of a comparatively steep pitchedelevating-screw 22, pivoted thereto at 23, and extending downwardly into a nut 24 which nut comprises a hand Wheel 25 journaled in aboot or sheave 26, located at the top of a bifurthe gadder-truck as at 28, 28.
The threadedhub of the hand-wheel 25 has an exterior annular groove 29 arranged to receive'a clamp 30, secured by bolts 31, passing therethrough and througl'i alined holes in lugs 32, one on each side of the boot 26. This, construction serves both to clamp the'nut against movement due to the vibrationof the drills and to prevent the nut from lifting out of the boot when the standard is raised toa nearly vertical position.
in operation, the standard is adjusted to the desired angle and height by turning the hand wheel 25, and secured by tightening one or both of the bolts 31. The carriage may then be raised or lowered by turning the wheel 20, and will be prevented from accidental movement on the ways 8 by reason of the worm drive. If it is desired to cut close to the 'roof or in a corner, the carriage may be raised until the upper clamp 11 projects beyond the upper end of the ways; or,
on the other hand, the lower clamp may be.
dropped close to the floor, and the lower drill work close in such corner. By locating the wheel 20 at the rear of the standard, the carriage may begiven its extreme range of travel without removing the driving means, as with the crank, gear and rack drive heretofore used,
In case the drill be adjusted to or near to the top of the standard 6, it frequently hapens that a rhythmic swing or motion is rated or t-frame 27, which ,is' pivoted to imparted thereto which seriously interferes I with the work of the drill, especially in starting a new hole, v
In order to provide for steadying or bracing the upper end of the standard I have provided the following: 33 is an adjustable clamp mounted on slide ways 37 arranged on the under side of the standard near its upper end, and similar in eneral construction to the ways .8. It is he (1 in place by set screws 34. From this slide or clamp projects a post 36, perforated to receive a suitable bracesuch as a steel bar-that is held in lace by the screw 35. The brace will be di erently used according to the location and circumstances of use of the gadder, but
usually one of its ends will bear against the face of thewall that is being operated upon.
What I claim is I v a standard movably mounted -adjust1n ard, an 1d1e sheave mounted at the free end 1. In a device of the class described, a base, thereon, a drill-supporting carriage movably mounted on saidstandard and adapted to support a plurality of drills, and means for securing said drills in working position beyond the ends of said standard.
2. In a device of the class described, an angularly adjustable standard, a drill-supporting carriage mounted on 'and capable of longitudinal adjustment along said standard, means on said carriage for supporting and clamping in position a drill and a similar means on said carriage, above the firstmentioned means, for clamping and supporting in position a second'drill, carriage means mounted upon said standof said standard, a flexible connection between,, said carriage and adjusting means passing around said sheave and attached to saidcarriage at a drill-supporting means.
3. In combination with the standard, of a rock drill gadder, and an adjustable ,dril l clamp or holder carried thereby, a brace holder 33 mounted upon sliding ways 37, on 'the underside of the standard-and near its upper end, and means for securing a brace in such holder.
In testimony whereof I afiix my signature, in presence of two witnesses.
' WILLIAM L. SMITH.
