Abstract
Abstract A saddle carriage is provided which is designed to fit onto a cycle stem and carry a saddle. The carriage comprises a support which can be secured to the cycle stem, the support having an upwardly concave, substantially horizontal, cylindrical sector which, in use, overhangs laterally relative to the stem. Superimposed upper and lower jaws are provided for gripping portions, e.g. wires of the saddle, the lower jaw having a lower surface which conforms to the cylindrical sector of the support. A nut and bolt or the like are provided for holding the jaws together, and the lower jaw or the support has a slot which permits relative displacement of the lower jaw and the support despite the presence of the bolt.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
167 words
A saddle carriage of the cradle and jaw type comprising an integral support and stem, said support provided with a substantially horizontal, upwardly concave, cylindrical sector overhanging laterally in relation to said stem, said support having placed thereon an assembly of upper and lower jaws adapated to encompass saddle wires of a saddle, the lower jaw being formed at its lower end with a convex, cylindrical sector complementary to the cylindrical sector of the support, a single screw for longitudinal movement only, disposed laterally relative to said stem, and extending upwardly through openings in said support and jaw assembly from bottom to top for fastening said jaw assembly to said support, and a fastening member on the upper jaw for securing said screw at its top end, and wherein said convex, cylindrical sector of said lower jaw has an enlarged opening therein through which said screw passes for allowing a change of position of said jaw assembly relative to said support without lateral movement of said screw.
Claim 2
Dependent Claim
167 words
A saddle carriage of the cradle and jaw type comprising an integral support and stem, said support provided with a substantially horizontal, upwardly concave, cylindrical sector overhanging laterally in relation to said stem, said support having placed thereon an assembly of upper and lower jaws adapated to encompass saddle wires of a saddle, the lower jaw being formed at its lower end with a convex, cylindrical sector complementary to the cylindrical sector of the support, a single screw for longitudinal movement only, disposed laterally relative to said stem, and extending upwardly through openings in said support and jaw assembly from bottom to top for fastening said jaw assembly to said support, and a fastening member on the upper jaw for securing said screw at its top end, and wherein said convex, cylindrical sector of said lower jaw has an enlarged opening therein through which said screw passes for allowing a change of position of said jaw assembly relative to said support without lateral movement of said screw.
Claim 3
Dependent Claim
14 words
A carriage according to claim 1, wherein said cylindrical sectors have roughened contact surfaces.
Claim 4
Dependent Claim
35 words
A carriage according to claim 1, wherein between adjacent surfaces of the cylindrical sectors there is interposed a strip of material having on each of its faces a surface with a high coefficient of friction.
Claim 5
Dependent Claim
24 words
A carriage according to claim 1 wherein the support and the lower jaw comprise side walls which co-operate to prevent their relative lateral displacement.
Claim 6
Dependent Claim
23 words
A carriage according to claim 1, wherein the radius of curvature of the cylindrical sectors is between 20 mm and 300 mm approximately.
Claim 7
Dependent Claim
95 words
A carriage according to claim 1 wherein said screw comprises a generally upwardly directed bolt having a head portion positioned in said support and a threaded top end portion, and said fastening member comprises an internally threaded member fastened to the top end of said bolt and mounted pivotally on the upper jaw for pivotal movement about an axis parallel to the generatrices of the cylindrical sectors, the lower jaw defining said enlarged opening at right angles to the generatrices to permit its displacement in relation to the support despite the presence of said bolt.
Claim 8
Dependent Claim
20 words
A carriage according to claim 1, wherein the end of the saddle stem is provided with a water tight cap.
Claim 9
Dependent Claim
51 words
A carriage according to claim 1, wherein the said support comprises a first part having a generally tubular portion whose exterior is slightly frusto-conical and whose interior defines a frusto-conical bore, and a second part in the form of a frusto-conical member sized for force fitting in the said frusto-conical bore.
Claim 10
Dependent Claim
33 words
A carriage according to claim 1 wherein the support comprises a steel sleeve sized for force fitting into the stem and an external skirt defining a groove which ends in an annular recess.
Claim 11
Dependent Claim
63 words
A carriage according to claim 1 wherein said upper jaw has an upper face formed in a cylindrical cup shape and wherein said fastening member has a lower portion shaped complementary to said cylindrical cup and pivotally mounted in said cup for allowing engagement with said cup during various positions of said jaw assembly relative to said support when said screw is tightened.
Claim 12
Dependent Claim
33 words
A carriage according to claim 10 wherein said screw has a threaded top end and wherein said fastening member has an internally threaded portion threadably engaged with said top end of said screw.
Claim 13
Dependent Claim
182 words
A saddle carriage of the cradle and jaw type comprising: (a) an integral support and stem, said support having a substantially horizontal, upwardly concave cylindrical sector overhanging laterally in relation to said stem; (b) an assembly of upper and lower jaws adapted to encompass saddle wires of a saddle, said lower jaw being formed at its lower end with a convex, cylindrical sector complementary to said cylindrical sector of said support; (c) a single screw extending upwardly through openings in said support and jaw assembly from bottom to top for fastening said jaw assembly to said support and disposed laterally relative to said stem, wherein said opening of said lower jaw sector through which said screw passes is enlarged for allowing a change of position of said jaw assembly relative to said support without lateral movement of said screw; and (d) a fastening member pivotally mounted on said upper jaw and secured to said screw at its top end for locking engagement with said upper jaw during various positions of said jaw assembly relative to said support when said screw is adjusted
Claim 14
Dependent Claim
182 words
A saddle carriage of the cradle and jaw type comprising: (a) an integral support and stem, said support having a substantially horizontal, upwardly concave cylindrical sector overhanging laterally in relation to said stem; (b) an assembly of upper and lower jaws adapted to encompass saddle wires of a saddle, said lower jaw being formed at its lower end with a convex, cylindrical sector complementary to said cylindrical sector of said support; (c) a single screw extending upwardly through openings in said support and jaw assembly from bottom to top for fastening said jaw assembly to said support and disposed laterally relative to said stem, wherein said opening of said lower jaw sector through which said screw passes is enlarged for allowing a change of position of said jaw assembly relative to said support without lateral movement of said screw; and (d) a fastening member pivotally mounted on said upper jaw and secured to said screw at its top end for locking engagement with said upper jaw during various positions of said jaw assembly relative to said support when said screw is adjusted
