VELOCIPEDE SEAT-SUPPORT.

Application filed May 5, 1897. Serial No. 635,208. (No model.)

.To all whom it may concern.-

Be it known that I, NORMAN T. SLEE, a citizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Velocipede Seat-Supports, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.

In the drawings, Figure 1 is a side elevation of my improved seat-support, which is illustrated with a horizontal bar which is adapted to have the saddle clamped to it, shown in full lines extending forward from the post and shown in dotted lines adjusted to extend rearward from the post. Fig. 2 is an axial section through the post fore and aft. Fig. 3 is a similar sectional View of a modi fied form, and Fig. 4. is a sectional view of a second modified form. Fig. 5 is a sectional view of a third modified form. Fig. 6 is a detail plan view looking in the direction of the arrow on Fig. 4 or Fig. 5, the appearance of the two forms shown in these two figures being identical as thus viewed.

The purpose of this invention is to provide a bar on which a velocipede-saddle may be adjusted fore and aft and which is adapted to be secured to the seat-post so that it may at the will of the rider be adjusted to extend either forward or rearward from the point of its attachment to the seat-post, so that the range of fore-and-aft adjustment which it will afford to the saddle may be as great as if it had arms extending both forward and rearward from its point of attachment to the post. Heretofore this result has been attained by actually extending arms both forward and rearward from an intermediate hub or stem, which affords means of fastening to said post, the device thus assuming a T shape, which is undesirable if it can be avoided.

The seat-post in bicycles of common construction is not vertical, but is inclined forward, and any device adapted to be adjusted with the saddle-holding arm projected at preference either rearward or forward must be contrived so that said arm shall be horizontal whether it is projected forward or rearward. For this purpose in the principal form shown in Fig. 1 I braze a plug B in the upper end of the seat-post A of the bicycle, said plug havinga threaded stern B projecting axially and having therefore, the same slope as the post and at right angles to the squared head of the ends of the post and shoulder of the plug.

0 is a seatsupporting arm having a hub C, apertured at the center to receive the threaded stem B, said hub making, with the arm 0, an angle which is the supplement of the angle of inclination of the seat-post that is, of the angle which measures the departure of the axis of the seat-post from vertical direction-such an angle, in short, that when the hub is lodged on the squared upper end of the inclined post and bound thereon by a nut B screwed onto the stem B above said hub, the arm 0 will project horizontally, as seen in Fig. 1. The two faces of the hub 0 being parallel and the axis of the aperture being at right angles to said parallel faces, and thereby at the same angle to the general longitudinal extent of the arm as the post is to horizontal direction, the device may be adjusted with its arm 0 projected rearward by taking it off the post and turning it over when it is thus reversed, reversing it in position at'the same time it is reversed in direction. plished by the modification shown in Fig. 3, in which the upper end of the oblique post A is cut off horizontally, making said upper end oblique to the axis, and from the center of the upper end and extending a verticallythreaded stem B, rooted in a plug B, whose shoulder at the root of the threaded stem is in a horizontal plane coinciding with the obliquely-cut end of the post. The saddle-supporting bar 0 may be made with a hub whose faces are parallel with the axis of the bar itself, and this seat-support maybe reversed in direction by rotating it on the threaded stem without turning it over.

The two methods above described for ac- 5 complishing the result may be employed in the modified forms shown in Figs. 4 and 5, respectively. In Fig. 4 the upper end of the A like result is accom- 8o.

inclined tubular seat-support is bent at such an angle to its axis as to terminate vertically, and around such vertically-terminating portion A the split hub C of the arm 0 is clamped by means of a clamping-bolt D taking through the lugs 0. In Fig. 5 the arm Chas a hub C split and provided with a clamping-bolt, as in Fig. 4, the hub, however, in this case being set at an angle to the arm C corresponding to the angle of the hub C in Fig. 1, and, with the hub, is clamped onto the upper end of the tubular seat-post, which terminates without change of direction-that is, in the customary way, as if to receive the ordinary support.

I claim 1. In a velocipede, in combination with a seat-support having an eye toward one end, an inclined seat-post having its upper end adapted to enter such eye to effect junction between said parts, and suitable means for securing the two parts together at such junction, one of said parts having, for the purpose of making such junction with the other part, a terminal which is deflected away from the horizontal plane through the point of deflection to cause it to extend at an obtuse angle to the general direction of extent of the part to which it pertains, which is the supplement of the angle of inclination of the seat-post from vertical direction.

2. In combination with an inclined seatpost, a seat-support reversibly secured at the upper end of the post comprising a seat supporting arm which makes an obtuse angle with the plane of rotation of the same about the seat-post, which is the supplement of the angle of inclination of the latter from vertical direction.

3. In a velocipede, in combination with an inclined seat-post which terminates at its upper end without change of direction; a seatsupport reversibly secured at the upper end of the post, such arm being apertured transversely to its longitudinal extent to adapt it to be applied to said upper end of the inclined post; the axial direction of the aperture being at an angle to the general longitudinal extent of the arm equal to the angle which the seat-post makes with the horizontal direction.

4. The combination of the inclined seatpost, the plug B in its upper end having the threaded stem l3 at the center, the seat-support having a horizontal arm C, and the oblique hub O adapted to be lodged about the threaded stem upon the seat-post, and suitable means for clamping it thereon, the seatsupporting arm making an obtuse angle with the hub which is the supplement of the angle of inclination of the seat-post from vertical direction.

In witness whereof I have hereunto set my hand, in the presence of two witnesses, this 29th day of April, 1897.
