SADDLE-PILLAR AND SADDLE ATTACHMENT FOR CYCLES.

Specification of Letters Patent.

Patented J nine St), 191 1.

Application filed June 19, 1912. Serial No. 704,595.

To all whom it may concern:

Be it known that I, SYDNEY MooDY, a subject of the King of Great Britain, residing at Plenty Itoad, Preston, in the State of Victoria, Commonwealth of Australia, mechanical engineer, have invented certain new and useful Improvements in Saddle-Pillars and Saddle Attachments for Cycles, of which the following is a specification.

This invention is directed to the provision of improvements in cycle saddle-pillars and also to attachments for securing saddles thereto in a very effective manner.

The improvements in the said attachments provide exceedingly simple, cheap and conveniently operated means of securing cycle saddles in or adjusting their position on saddlepillars and provision is made in the devisal of the latter to prevent any oscillatory movement of the saddle when in use even when subjected to unusually severe side strains.

hioreover the invention comprises improvements in means for securing saddlepillars to the machine frame.

In order that the invention may be readily understood reference will now be had to the accompanying sheet of explanatory drawings, wherein:

Figure 1 is a View in side elevation of a saddle-pillar means for supporting the same rigidly within the machine frame and a seat clamp constructed according to the present invention. Fig. 2 is a view in end elevation of part of Fig. 1 While: Fig. 3 is a view in side elevation of partof a saddle-pillar showing a seat clamp in an alternate position. Figs. 4: and 5 are views in detail of the improved seat clamp, and Figs. 6 and 7 are views showing a modified form of seat clamp which may be substituted for that shown in Figs. 1 to 5.

In these drawings like characters of ref erence have been employed to indicate similar parts in the different views, and in carrying the invention into practical eflect the horizontal part of the saddle-pillar (z is provided with a longitudinally disposed rib, feather or key 6 which may be secured in position by means of brazing or other approved means but is preferably formed in tegrally and worked up out of the metal forming the said horizontal part or that to which the seat is clamped. An open sleeve or boss forming a clamp or bracket 0 and having two flat sides arranged parallelly with the opening (Z therein is adapted to fit over the horizontal part of the pillar a and is normally free to slide thereon. The open side of the clamp or bracket 0 may be of greater thickness than any other part thereof and formed transversely therethrough is a hole adapted to receive a double ended clamping bolt 6 of ordinary design. This said bolt 6 is preferably square though it may be of any other approved shape in cross section that will prevent its rotation in the said clamp c and its outer end is fur nished with washers f plate 9 and nuts it. The said Washers f may be plain as shown or formed with suitably disposed recesses to receive the wire springs z of the saddle (not shown) and the said nuts 71 may be tightened to clamp the said springs 2' securely between the washers f and plate 9 and incidentally the clamp o to the horizontal part of the saddle-pillar a. It will be readily understood that the underside of the clamp c is made sufliciently thin to permit of it springing open to freely pass over the pillar extension and to insure a freedom of adjustment when the nuts 71, are partially unscrewed.

In order to permit of the saddle being tilted to and retained at any desired angle the contiguous faces of the plate 9 and the clamp c are provided with radially disposed serrations or recesses y' similar to those at present employed for effecting the abovementioned object.

The rib, feather, or key 6 may be located above the horizontal part of the saddlepillar a as shown in 1 of the drawing or it may be situated therebelow as shown in Fig. 3. These alternate forms of construction permit of the clamp 0 being supported above or suspended below the said horizontal part or extension of the saddle-pillar, as shown. The two parts forming the saddlepillar a may beconnected by a lap joint or by an angle piece as shown in Figs. 1 and 3 respectively. The sides of the opening (Z in the clamp a are adapted to bear against opposite sides of the feather b and so prevent any oscillation or side movement of the saddle. The sides of the clamp o extend upwardly and are formed with two inwardly projecting abutment members 70 which are adapted to bear against each other when the nuts h are tightened by the bolt 6. The said abutment members 7a are of su'tlicient length to permit of them meeting before the sides of the opening (Z bear against the rib, feather or key 6. By forming the clamp 0 in the manner above described the sides of the same are prevented from being squeezed inwardly too much out of the vertical while the clamp can be i'nade to grip quite tightly on the extension. If preferred only one abutment member It may be formed on the clamp in which case. it will be made sufficiently long to permit its end to bear on the opposite side of the said clamp when the same is tightened by means of the bolt 0.

In an alternate construction the clamp 0 can be stamped out of sheet metal in two pieces as shown in Figs. 6 and 7 in which case the upper end of the outer part may be provided with inwardly projecting parts or abutment members 70 formed integrally therewith. These parts 70 are intended to bear a ainst each other in the manner hereinbefore described and the opening (Z in this instance is made between opposite faces of the parts Z which are retained in position by the overlapped portions m of the outer part of the clamp.

ihe inclined member-of the saddle-pillar may be made in the ordinary way and can be retained in position within the bicycle frameby means of a jam nut and bolt (not shown) or by any other well known device. In lieu of making the saddle-pillar of plain tubing it can be formed with a rib, feather or key it of similar construction to that atlixed to or formed on the horizontal part of the saddlepillar. The feather n is adapted to fit within a recess 0 formed in a thickened part of the seat lug 7), see Fig. 1. The said feather n and recess 0 in the lug p effectually prevent the saddle-pillar being turnedeven when subjected to considerable strain and thus insures the saddle remaining in its correct position. This form of saddle-pillar may be retalned fixedly in position by a bolt 9 passing through lugs 1' on the seat lug p in the ordinary way.

The mode of operation and manner of effecting any desired adjustment of the invention will be readily understood from the description hereinbefore contained and fur thermore it will be obvious that various slight and immaterial modifications may be made in the construction of the same without departing from the scope of the following claiming clauses.

Having now 'fully described and ascertained my said invention and the manner in which it is to be performed, I declare that what I claim is 1. The combination of a pillar for cycle saddles formed of tubing having an approximately horizontal extension, a rib on said pillar extension, a clamp mounted on the extension having inwardly projecting abutment members on the ends thereof, and an opening below said abutment members, said members being of suflicient length to permit of their n'ieeting before the sides of said opening bear against said rib, and means for drawing the ends of the clamp together.

2. In a pillar for cycle saddles, the combination of an extension having a rib, feather or key fitted to or formed thereon, a seat clamp having a longitudinal opening therein, the sides of said opening adapted to bear against said rib, feather or key, inwardly projecting abutment members on the open end of said clamp, a bolt passing through said clamp and furnished with plates, washers and nuts, substantially as and for the purposes set forth.

In witness whereof I have signed this specification in the presence of two witnesses.

SYDNEY MOODY.
