Description
JASPER NUTEN RICKLES, ALTOONA,
MINING-DRILL.
Specification of Letters Patent.
Patented March 5, 1907.
Application led May 5,1906. Serial No. 315,443.
To all whom t may concern:
Be it known that I, JASPER NUTEN RIcKLEs, a citizen oil the United States, residing at Altoona, in the county of Etowah and State oi Alabama, have invented a new and useful Mining-Drill, of which the following is a specification.
This invention relates more particularly to manually-operated drills for mining coal and the like in con'ned places, but is clearly applicable for use in other analogous relations and is therefore not limited in this respect.
The principal object is to provide an eX- ceedingly simple implement which can be conveniently held and operated and is capable of ready adjustment in order to alter the speed, and thereby the force, of the drill or driven member with respect to that of the driving members.
The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of the drill. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a cross-sectional view on the line 3 3 oiFig. 2. Fig. 4 is a detail elevation oi a portion oi the supporting-frame.
Similar reference-numerals designate corresponding parts in all the gures of the drawings.
In the embodiment illustrated a supporting -frame is employed which includes a shank 5, provided at one end with a transversely-disposed presser-head 6 and at the other end with spaced longitudinally-disposed webs 7, said Webs being connected at their outer ends by an integral sleeve 8. The shank 5 is provided with alongitudinal slot 9, and one of the webs is also provided with a longitudinal slot 10. A driven shaft 11 is j ournaled longitudinally in the frame, being rotatably mounted in the sleeve 8 and in the adjacent end of the shank 5, as shown in Fig. 2. An oppositely-beveled gear-wheel 12 is iXed to the shaft between the webs 7, and the end o1c said shaft which projects beyond the sleeve 8 carries a bit-socket 13, which may be of any suitable structure.
Adjustably mounted in the slot 9 is a supporting device in the form of a stud 14, one end of which projects from one side of the frame, forming a journal-pin 15. A clamp 16, consisting of a nut and washer, serves to normally hold the stud against movement in the slot. Another supporting-stud 17 is slidably mounted in the other slot 10 and is normally held against movement by a clamp 18, consisting or a plate and screw, as shown in Fig. 3. rlhe stud 17 is provided with an offset bracket 19, carrying a journal-pin 20. Rotatably mounted on the journal-pins 15 and 2O are driving members comprisinghandle-cranks 21, that are thus located on opposite sides of the supporting-frame and on opposite sides of the gear-wheel 12. Both of these handle-cranks have gear-wheels 22, and each oiE said gear-wheels 22 has a plurality of annular sets of teeth 23. Either of these sets is movable into mesh with the adjacent beveled portion of the gear-wheel 12 upon the loosening or' the studs and their adjustment in the slots 9 and 10 of the support- 'ing-frame, as will be evident by reference to Fig. 2.
It will thus be evident that if the drill-bit is placed in the socket 13 the same may be rotated at comparatively high speed by meshing the outer set of teeth 23 of the gear-wheels 22 with the gear-wheel 10. On the other hand, a slower speed and greater power may be imparted to the drill by adjusting the driving-cranks so that the inner sets of teeth 23 will mesh with the pinion or gear-wheel 12.
From the foregoing it is thought that the construction, operation, and many advantages oi the herein-described invention will be apparent to those skilled in the art Without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacrificing any of the advantages of the invention.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Fatent, is-
1. In a drill of the character described, the combination with a supporting-frame, of a shaft j ournaled therein, said frame having a longitudinally-disposed slot at one side of the shaft, a bracket slidable on the frame and eX- tending over the shaft, fastening means for the bracket passing through the slot, a gear mounted on the shaft, and a gear mounted on thefbracket intermeshing with the gear of the sha t.
2. In a drill of the character described, the combination with a supporting-frame having longitudinallydisposed slots, of a driven shaft journaled in the frame, one of the slots being disposed in substantial alinement with the shaft, the other being located longitudi- TOO l movement, said means being located in the slot, a handle-crank mounted on the bracket,
another handle-crank having an adjustable l mounting on the supporting-frame in substantial alinement With the shaft, intermeshing gearing carried by the handle-cranks and shaft, and tool-holding means mounted on the shaft. f 4. In a drill of the character described, th combination With a supporting-frame having a presser-head at one end and provided With longitudinally disposed slots, of a driven shaft mounted longitudinally in the frame, said shaft having an oppositely-beveled gear- Wheel and a bit-socket, one of the slots being disposed in line With the shaft, the other being located at one side of the same, studs longitudinally adjustable in the slots, clamps for holding the studs against movement in said slots, handle-cranls mounted on the studs and located on opposite sides of the gear- Wheel, and gear-Wheels carried by the handlecranks, and each having a plurality of annular sets of teeth, either of which are movable into mesh With the gear-Wheel of the shaft upon the adjustmentof the studs.
In testimony that I claim the foregoing as my oWn I have hereto affixed my signature in i the presence of two Witnesses.
