Claim 1
Independent Claim
230 words
A guitar bridge comprising: a main body having a plurality of transversely spaced openings formed therein for receiving a plurality of longitudinally adjustable saddles, each of said openings having upper shoulders formed in the side upper ends and lower shoulders formed in the side lower ends, each of said saddles being positioned in a corresponding one of said openings wherein each of said saddles comprises a string receiving portion and a holding portion, said string receiving portion having a concave impression in its upper surface adapted to receive a guitar string, and having its lower surface engaged with and supported by said upper shoulders, said holding portion fitting within said opening and having laterally extending flange portions resting on said lower shoulders, said holding portion having a threaded hole extending therethrough for receiving an adjusting screw; an adjusting screw extending in a fore-and-aft direction through said opening and through said threaded hole and operable, upon rotation, to adjust the position of said saddle in a fore-and-aft direction, and to maintain said saddle in its adjusted position; and a holding screw passing through said string-receiving portion and said holding portion, connecting said portions and operable upon tightening of said holding screw to maintain said string-receiving portion and said holding portion in firm contact with said upper shoulders and lower shoulders, respectively, to prevent undesired lateral or rotational movement of said saddle.

Claim 3
Dependent Claim
179 words
A guitar bridge having a main body formed with a plurality of openings, each of said openings having upper and lower shoulders on the sides thereof, an adjusting screw extending in a fore-and-aft direction through one of said openings; a saddle positioned in said one opening and having a string-receiving portion and a holding portion, said string-receiving portion having its lower surface positioned on said upper shoulders for sliding movement thereon, and having a concavity in its upper surface for receiving a guitar string, said holding portion being positioned within said opening and having flanges at its lower portion for engaging said lower shoulders, and having a threaded hole extending therethrough for receiving said adjusting screw, whereby rotation of said adjusting screw will cause fore-and-aft movement of said holding portion; and a holding screw connecting said string-receiving portion to said holding portion for movement therewith, and arranged so that tightening of said holding screw will maintain said holding portion and said string-receiving portion in firm contact with said lower and upper shoulders, respectively, to prevent vibration of said saddle.
Claim 4
Dependent Claim
179 words
A guitar bridge having a main body formed with a plurality of openings, each of said openings having upper and lower shoulders on the sides thereof, an adjusting screw extending in a fore-and-aft direction through one of said openings; a saddle positioned in said one opening and having a string-receiving portion and a holding portion, said string-receiving portion having its lower surface positioned on said upper shoulders for sliding movement thereon, and having a concavity in its upper surface for receiving a guitar string, said holding portion being positioned within said opening and having flanges at its lower portion for engaging said lower shoulders, and having a threaded hole extending therethrough for receiving said adjusting screw, whereby rotation of said adjusting screw will cause fore-and-aft movement of said holding portion; and a holding screw connecting said string-receiving portion to said holding portion for movement therewith, and arranged so that tightening of said holding screw will maintain said holding portion and said string-receiving portion in firm contact with said lower and upper shoulders, respectively, to prevent vibration of said saddle.
Claim 5
Dependent Claim
178 words
A guitar bridge having a main body formed with a plurality of openings, each of said openings having upper and lower shoulders disposed at both sides thereof, an adjusting screw extending in a fore-and-aft direction through one of said openings; a saddle positioned in said one opening and having a string-receiving portion and a holding portion, said string-receiving portion having a lower surface adapted to ride on said upper shoulders for sliding movement thereon, and having a concavity in its upper surface for receiving a guitar string, said holding portion having an upper surface adapted to engage said lower shoulders; a holding screw connecting said string receiving portion to said holding portion for movement therewith, and arranged so that tightening of said holding screw will maintain said string-receiving portion and said holding portion in firm contact with said upper and lower shoulders, respectively, to prevent vibration of said saddle; and a threaded hole extending through a portion of said saddle for receiving said adjusting screw, whereby rotation of said adjusting screw will effect fore-and-aft movement of said saddle.
