ADJUSTABLE SADDLE-SUPPORT.

SPECIFIGATIUN formingpart of Letters lPatent No. 634,096, dated October 3, 1899.

Application filed December 14,1896 Serial No. 615,586. (No model.)

To all whont it may concern: I

Be it known that I, CHARLES S. SMITH, of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain new and useful Improvements in Adjustable Saddle-Supports for Bicycles; and I do hereby declare that the following is afull, clear, and exact description of the invention, whichwill enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The main objects of my invention are to admit of lowering the saddle to the fullest ex tent without interfering with its adjustment, to facilitate tilting the saddle forward or backward, and generally to simplify and improve the fastening bywhich itis secured to the seatpost.

It consists, essentially, of a seat-post provided at its upper end with two opposing transversely-disposed jaws and a screw'for. clamping said jaws on the saddle-bar and of certain novel features of construction hereinafter particularly described, and pointed out in the claim.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure 1 is a vertical longitudinal section of abicycle-saddle and of a portion of the frame, showing my improved seat-support inside. elevation. Fig. 2 is an enlarged view .of the seat-post detached looking from the left with reference to Fig. 1 and showing the adjustable fastening in section on the line 2 2, Fig.- 5. Fig. 3 is a section on the line 3 3, Fig.2; Fig. l, a section on the line 4 4, Fig. 3; and Fig. 5, a section on the line 5 5, Fig. 2.

Adesignates a bicycle-saddle provided with a downwardlycurved spring or supporting bar B, which in the present instance is in the form of a flat metal band or single leaf-spring. To the front and rear ends of this barthe saddle is attached in the usual or any suitable manner.

C designates the seat-post, which for'the sake of economy and lightness is drawn from sheet metal into tubular form. It is fitted into and adjustable vertically in the upper end of the upright D of a bicycle-frame, as shown in Fig. 1. At its upper end the seat-post is formed into a transverse selnicylindrical seat 0, in which is fitted and brazed a tubular head E, closed at one end and open and internally threaded at the other. The ends of this tubular head form sockets or pockets,which face jectionsff, adapted to engage with opposite sides of the saddle-bar B. The upper side of the tubular head E is cut away sufficiently to receive the saddle-bar B between the jaws F Fand below the inward] y-proj ecting lips f f when the latter are turned to .the. upper part of the sockets in which they are held.

G is a screw threaded in the open end of the tubular head E and adapted to hear at its inner end against one of the jaws F and to force and hold it against the saddle-bar B, thereby clamping and rigidly holding said bar and the saddle supported thereon in any desired position. It is formed at its outer end with a squared head,fwhich projects beyond the tubular head E and is easily accessible in any position of the seat-post and saddle with a wrench. By turning said screw out and slackening up on the adjacent jaw the saddle-bar may be-slipped forward or backward in the head and the inclination of the saddle changed as desired. With this form of seat-post and saddle-fastening the saddle can be lowered until the head of the seat-post rests upon the upper end of the upright D without preventing easy access to the adjusting-screw G or interfering with the adj ustmentof the saddle.

In addition to the advantages above stated m improved construction possesses the further advantages of. simplicity, compactness, and efficiency.

It will be observed that the projections ff on the jaws are inclined on their under faces that engage with the saddle-bar B and that when they are brought into engagement with the saddle-bar the vertical faces of the jaws do not come into contact with the sides of said bar. The tendency of the jaws when clamped upon th e;bar to tip it sidewise is thus avoided and the bar is forced and held firmly down upon the upper edges of the seat Aseat-post for bicycles, consisting of a tubular stem and a transverse tubular head closed at one end, open at the other which is internally threaded, and cut away on the upper side between its ends, which form in wardly-opening sockets or pockets, opposing cylindrical jaws fitted in said sockets and having! inwardly-projecting lips on one side of their inner ends, and a screw threaded in the outer end of one socket, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own afiix my signature in presence of two witnesses.

CHARLES s. SMITH.
