Claim 1
Independent Claim
353 words
A drill guide comprising a shaft on one end of which a power drill may be attached and on the other of which a drill bit holdeR is attached, frame means rotatably carrying said shaft for rotation of said shaft about an axis, an elongated forward drilling motion directing member extending in spaced parallelism with said shaft, means adjustably attaching said frame means to said directing member in a manner for adjustment of said shaft toward and away from said directing member and also for rotational adjustment of said shaft and frame means by swinging about a longitudinal axis through said directing member, said means adjustably attaching said frame means to said directing member comprising a clamping block assembly comprising two clamping block means disposed one on each of two opposite sides of said directing member movable with respect to each other so as to be clampable against opposite sides of said directing member, said block means being rotatable around the outer surface of said directing member about an axis extending longitudinally through said directing member, said frame means having at least one elongated portion disposed on an opposite side of said clamping block assembly, pressing means engageable with said at least one elongated frame portion and releasably pressing said at least one frame portion against one of said clamping block means to releasably fix the position of said at least one elongated frame portion with respect to said clamping block means, and said pressing means also causing a pressing of said two clamping block means tightly against opposite sides of said directing member, said drill guide further comprising a body member, means slidably mounting said directing member on said body member for longitudinal movement of said directing member with respect to said body member, said directing member and said body member having key and keyway means thereon to prevent rotation of said directing member with respect to said body member, and longitudinal movement causing means cooperatively correlated with said directing member and engageable with said body member for causing a longitudinal movement of said directing member with respect to said body member.
Claim 2
Dependent Claim
353 words
A drill guide comprising a shaft on one end of which a power drill may be attached and on the other of which a drill bit holdeR is attached, frame means rotatably carrying said shaft for rotation of said shaft about an axis, an elongated forward drilling motion directing member extending in spaced parallelism with said shaft, means adjustably attaching said frame means to said directing member in a manner for adjustment of said shaft toward and away from said directing member and also for rotational adjustment of said shaft and frame means by swinging about a longitudinal axis through said directing member, said means adjustably attaching said frame means to said directing member comprising a clamping block assembly comprising two clamping block means disposed one on each of two opposite sides of said directing member movable with respect to each other so as to be clampable against opposite sides of said directing member, said block means being rotatable around the outer surface of said directing member about an axis extending longitudinally through said directing member, said frame means having at least one elongated portion disposed on an opposite side of said clamping block assembly, pressing means engageable with said at least one elongated frame portion and releasably pressing said at least one frame portion against one of said clamping block means to releasably fix the position of said at least one elongated frame portion with respect to said clamping block means, and said pressing means also causing a pressing of said two clamping block means tightly against opposite sides of said directing member, said drill guide further comprising a body member, means slidably mounting said directing member on said body member for longitudinal movement of said directing member with respect to said body member, said directing member and said body member having key and keyway means thereon to prevent rotation of said directing member with respect to said body member, and longitudinal movement causing means cooperatively correlated with said directing member and engageable with said body member for causing a longitudinal movement of said directing member with respect to said body member.
Claim 3
Dependent Claim
122 words
The combination of claim 1 in which said at least one elongated frame portion has a longitudinal slot therethrough extending at a right angle to said shaft, said pressing means comprising a lock bolt means having a shank extending through the slot of said at least one elongated frame portion and also through at least one of said clamping block means and at least into the other of said clamping block means, said lock bolt having a shoulder means thereon engageable with that side of said at least one elongated frame portion which is the side thereof which is opposite said clamping block assembly, and said lock bolt having an engageable means thereon for facilitating its rotation for clamping and release motions.
Claim 4
Dependent Claim
31 words
The drill guide of claim 2 in which said longitudinal movement causing means comprises teeth on said directing member and a gear rotatably mounted on said body and engaging said teeth.
Claim 5
Dependent Claim
30 words
The combination of claim 1 in which said longitudinal movement causing means comprises teeth on said directing member and a gear rotatably mounted on said body and engaging said teeth.
