ANCHOR FOR DRLL-STEEL GUIDES.
Application filed January 13, 1927.
The present invention relates to guides or drill steels of the type shown in the application for patent ot Richard Grillitl'i, Serial No. 146,515), filed November 11, 1926. It has been found that the anchoring means disclosed in said Grillith application, while ellec-tive to hold the guide in place, has a wedging action so powerful that it' the initialihole is close to the edge ot the rock, there is a material tendency to fracture the rock and sometimes to break oil' the section between the hole and the side ot the rock tace.
The object ot the present .invention is to provide an anchoring means that is adjustable so that the anchoring wedge can be brought against a side wall ot the opening ot suliicient thickness to prevent the above difficulty.
ln the accompanying drawings 1T igure 1 is a side elevation of the preferred embodiment ot the invention,
Figure 2 is a plan view of the same,
Figure 3 is an end elevation.
rlhe body of the guide is designated. 41T, and is provided with a series of parallel openings 5 for thereception of the drill steel. A bushing 6 is employed that is placed in the diliierent openings in succession as the drill steel is moved from one to the other, the drill steel being shown at 7. Passing through one end ol' the body, is an opening 8 to receive a holding spur 9 secured in place by set screws 10. i
In the opposite end ot the body is formed a vertical guideway 11, in which is rotatably and slidably mounted an anchor rod or .stem 11. adapted to engage in the initially drilled hole 12 in the rock. This rod or stem is provided with a longitudinal keyway 13, the lower end of which tapers outwardly, as shown at 11i. rlhe guideway 11 provided in at least three of its sides with keyways 15. A wedging key 1G is adapted to be slidably engaged in the keyway 13 and .in any one ot' the heyways 15, depending on the position assumed by the anchor stem when it is rotated. The lower end ot this wedging key is tapered as shown at 17, and when the key is driven downwardly, it will wedge securely against the wall of the drill holt-i12, thereby fastening the anchor stein in place. The outer side or edge of the wedge key 16 is provided with a series o'f Serial No. 166,958.
undercut teeth or shoulders 18 adapted to be engaged by a releasing tool, and the end ot the body tis provided in .line with the lieyways with .recessed ulcrum seats 1%) on which the releasing tool or lever is adapted to rest.
`W ith this c mstruetion, it will bc evident that even though the hole 12 is partly closed to the side face of the rock, the body can be differently positioned and the anchor stem or rod can be turned so that the wedge can be inserted against a portion ot lthe rock having suliieient body to withstand the wedging action.
`From the foregoing, it is thought that the construction, operation and many advantages ol 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.
What we claim is:
1. In a rock drill guide, the combination with a body having a guideway for a drill steel, of means rotatably mounted in the body and engaging in a drilled hole for positioning the body with a` guideway;V in a predetermined position over the rock to be drilled, and means mounted on and adjustable to dil'lerent positions when the positioning means is rotated for securing raid positioning means in different positions against rotation.
2. In a rook drill guide, the combination with a body having a guideway ilfor a drill steel, of an anchor stem rotatably mounted in the l'iody and engaging in a drilled hole ior positioning the body with the guideway in a predetermined position over the rock to be drilled, and a clamping wedge that is slidably interlocked with the anchor stem and is adjustable to different positions when the stem is rotated.
3. lu a rock drill guide, the combination with a body having a guideway for a drill steel, of an anchor stem rotatably mounted in the body and engaging in a drilled hole for positioning the body with the guideway in a predetermined position over the rock to be drilled, and a clamping wedge that engages the anchor stem and is adjustable to different positions when the stem is rotated, said Wedge having a portion adapted to be engaged by a releasing tool, and said body having diiferent portions adapted to act as fulcrums for a toolV engaging said portion. n
4. In a rook drill guide, the combination With a body having a guideway for a drill steel, of an anchor stem capable of sliding and rotatable movement in the body7 said anchor stem having a longitudinal keyway in one side, and a locking' key slidable in the lzeyWa-y and having shoulders for engagenient by a releasing tool, and said body having different portions on different sides of the anchor stem that constitute fulcrums ior Ysuch tool.
5. In a rock drill guide, the combination lwith abody having a pluralityof guideways for a drill steeland having a bore at one Vend provided With a plurality of longitudr and adapted to engage in any of the guideways of the bore with which the keyway of the anchor stem alines.
6. In a rock drill guide, the combination with a body having a plurality of gliideways for a drill steel and having a bore at one end provided with a plurality of longitudinal leyways and fulcrums seats on different sides of the bore in line with the keyways,
