Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
174 words
Arrow adjusting apparatus for use with bow, comprising: (a) a main support, (b) mounting means for attaching the main support to the bow so that one end of said support extends rearwardly of the bow, (c) a threaded spindle which extends transversely through said one end of the support for rotational and axial movement relative to said one end, said spindle having an arrow rest at one end, (d) a nut threaded on the spindle so that rotation of the nut causes said spindle to move axially relative to the support, and (e) locking means for selectively locking said spindle against rotation relative to said support while permitting the spindle to move axially relative to said support, wherein the said one end of the support is provided with a slot and wherein said locking means consists of a block which lies within said slot, said block having an aperture through which said spindle extends for axial sliding, but non-rotative, movement relative to said block and clamping means for clamping the block to the support.
Claim 2
Dependent Claim
174 words
Arrow adjusting apparatus for use with bow, comprising: (a) a main support, (b) mounting means for attaching the main support to the bow so that one end of said support extends rearwardly of the bow, (c) a threaded spindle which extends transversely through said one end of the support for rotational and axial movement relative to said one end, said spindle having an arrow rest at one end, (d) a nut threaded on the spindle so that rotation of the nut causes said spindle to move axially relative to the support, and (e) locking means for selectively locking said spindle against rotation relative to said support while permitting the spindle to move axially relative to said support, wherein the said one end of the support is provided with a slot and wherein said locking means consists of a block which lies within said slot, said block having an aperture through which said spindle extends for axial sliding, but non-rotative, movement relative to said block and clamping means for clamping the block to the support.
Claim 3
Dependent Claim
51 words
Arrow adjusting apparatus as recited in claim 1, wherein the block is in the form of a disc whose axis is concentric with the spindle and fits snugly between the sides of the slot in the support, and wherein the spindle is provided in its central portion with a non-circular cross-section.
Claim 4
Dependent Claim
96 words
Arrow adjusting apparatus as recited in claim 2, wherein the disc has a threaded radial bore and the slot in the support is defined by two spaced, parallel end portions, the end portions having semi-cylindrical portions that are concentric with and are extensions of the corresponding surface of the disc, and wherein said clamping means comprises: (a) a bridge which extends across the end portions and across the slot adjacent the cylindrical surface of the disc, and (b) a screw mounted on the bridge for selective engagement with said threaded radial bore for clamping the support.
Claim 5
Dependent Claim
50 words
Arrow adjusting apparatus as recited in claim 1, wherein the arrow rest is in the form of a thin metal plate fastened to and extending radially from the spindle at the said one end, and wherein the opposite end of the spindle is provided with threads and carries the nut.
