- Figure is a centralvert-icalflengitudinal sechorn-showing"the forwarding mechanism and the registering device f0r'the feed bar; moan-enlarged scale;
- The-gear end-of the tube '20 is d 'w'ith; a flange 2; shown I in contact with the irbnt end at the housing In.
- the tlibe 211 supports inbearings; a '-pini0n'-23 in engagement With-the teeth 254 of the;rack bar!!.
- the steady pin 36 is carried at the forward end of a stem 33 which can slide in a bore 33 at the front end of the feed bar 9, and the steady pin 36 is pressed forwardly by a strong coiled compression spring 40 engaging under the head of the pin 33 and against the front of the feed bar 9.
- the spring 4 is compressed and holds the pin 3t against the rock face.
- the stem 38 is guided by a set screw 4
- the drill proper -53 ( Figure l) is held in a chuck 44- mounted on the driving shaft 45 in the front of the drill housing 33.
- the shaft 55 and drill 43 may be driven by an electric motor carried in the housing 66 through suitable reducing gearing, the electric motor being supplied through a trailing cable 47.
- the drill housing 46 is supported by a pair of lugs 63 secured to a tube d3 connected by a parallel key or feather 50 to the feed bar 9.
- Behind the housing 43 and abutting against the tube 49 is a tube also connected to the feed bar 9 by a parallel key or feather 52 so that both the motor housing 45 and the tube 5
- the feed bar 9 can be rotated in the tubular mounting but when so rotated it causes the tubes and 5
- the drill rods or tools 43 can clearly be changed rapidly without disturbing the general setting up of the equipment, for example if a hole has been drilled with'a three foot drill rod 33, this rod can be uncoupled at the chuck '44, the handle 27 removed and, with the locking pawl in the housing 5! disengaged, the drill housing 46 with the tube 5i can be quickly drawn back, the drill rod 43 withdrawn from the hole in the rock face and a longer drill rod inserted in its place. The drill housing 56 is brought forward again and the longer drill rod 43 coupled up to the chuck 54 ready for further drilling.
- a rotary rock-drilling equipment comprising in combination, a fixed supporting prop, a tubular mounting secured to said prop, a drill feed bar formed with rack teeth and mounted to slidein said tubular mounting, a rock-engaging steady pin resiliently mounted at the forward end of said feed bar, a first pinionmeshing with the rack teeth of said feed bar and journalled to thrust against said mounting when rotated to press said feed bar forwardly, a drilling unit supported on said feed bar and mounted to slide thereon to and from said rock-face, a second pinion meshing with the rack teeth of said feed bar and journalled to feed said drilling unit forwardly When rotated and a ratchet handle formed to engage alternatively each of said pinions to rotate the respective pinions in one direction.
- a rotary rock-drilling equipment also comprising a sleeve splined to said feed bar and located immediately in front of said tubular mounting and formed with bearing for said first pinion and a second identical sleeve splined to said feed bar and located immediately to the rear of said drill unit but reversed with respect to said first-named sleeve and formed with bearings for said second pinion.
- a rotary rock-drilling equipment according to claim 2, also comprising manually-operated meansfor locking said first pinion against rotation.
- a rotary rock-drilling equipment wherein said feed bar is mounted for rotatable adjustment in said tubular mounting and said drilling unit is splined to said feed bar and bears a drill chuck offset from said feed bar so that the drill chuck acquires a fresh setting on adjustment of said feed bar and said drilling unit, said equipment having means for maintaining said feed bar in adjusted position.
- a rotary rock-drilling equipment comprising in combination a fixed supporting prop, a tubular mounting secured to said prop, a drill feed bar mounted for rotatable adjustment in said mounting, a sleeve adjacent to said mounting and splined to said feed bar and rotatably adjustable therewith, a drilling unit splined to said feed bar so as to slide thereon to and from the rock face to be drilled and bearing a drill chuck offset from said feed bar so as to acquire a fresh setting on adjustment of said feed bar in said mounting, locking means carried by said sleeve and said mounting, engageable to maintain said sleeve and feed bar in selected angular adjustment with respect to said tubular mounting and means for feeding said drilling unit along said feed bar towards said rock face.
- a rotary rock-drilling equipment comprising a notched flange coaxial with said sleeve and a transversely pivoted latch engageable with the notches of said flange to maintain said sleeve in a definite angular adjustment with respect to said tubular mounting,
