Definitions
- thefinvention consists of the combination of elements and arrangement or" parts'having the general modeflof operation substantially as hereinafter described and Figurel is asectionaljelevation ofa rock drill having the inventionapplied'thereto,
- Figure 2 is a transverse View taken through tioncup.
- FIG. 1 F Fi ure l-is a'perspective view of the rotation cover, and a 5 Figure5 is a perspective view of the rota Referring to dr gs; the invention is ""shown'emb odied in a rock drill having a pylinderA' provided-with a hammer piston B reciprocable in the cylinder for delivering blows of impact to a working implement (not shown) extending into the front'end of the rockdrill. ij, 1 a s v v 'On the rearward'end of the cylinder A is disposed aback cylinder C having a hollow extension 1) which projectsinto thecylinder VA to guide the hammer piston B.
- the rear- .;erative position inany suitable manner, as v for'instance, by the side bolts G disposed on i Pressure fluid for actuating the drill may. be conveyed from a suitable source of supply -5 (notshown) by a connection H attached to 'oppo'sitesides of the drill.
- the rotation ring E'andthe back :cylinder conveys the pressure fluid from the connection H to a throttle valve K in the back cylinder OQ
- the throttle valve K maybe of a ,well known type and is adapted to control the admission of pressure fluid into theback cylinder 0 where it may be distributed bythe ,piston B in a well known manner.
- Suitablemeans are provided for imparting a stephy step rotative movement to the workmg implement preparatory to the deliverylof the blow of the hammer piston thereto.
- a fluted rifle bar L which is journalled in the back head F at one'end and also ,inthe back cylinder C extends throughjthe' said back cylinder and"interlocks slidably with a fluted rifle nut O in the rearward end of the piston'B.
- the riflexbar L is a cam P in the form of a parallelogram having two long straight sides Q, and end surfaces R inclined'withrespect to the sidesf Q, but parallelwith respect to each other.
- the cup S is adapted to'rotatein the rotation ring andhas .a central aperture T in its front end to rotatably receive, therifle harL.
- a closure is provided forJt-he rearward end of the cup S in the form of a' cover U which has a cylindricalbody portionqV adapted to fit snugly in the rearwardend ofthe cup S.
- said cover is provided with pair of diametrically opposed wings W which in the assembled position seat into notches Xin the rearward end of the cup S,
- the cover U are formed longitudinal slots Y and Z respectively whichin the assembled position of these elements will be in alignment with each other to serve asguides for rollers b adapted to be pressed between the end surfaces.
- the cover U also hasa central aperture 0 to receive the rearward end of the rifle bar'L for which. itif rrns a bearing V cam P, thus at all times assuring the correct The heyam 'z w erem;
