art to which it appertains to make and use'the.
same.
The general object of this invention is to. provide a post that in appearance, conven-- ience and cost shall be more satisfactory than those ordinarily in use.
More specifically, the object is to produce a post thatshall at all times keep the saddle in the plane of the machine, that shall allow front and rear adjustment of the saddle with reference to the point of support, and change of the saddles inclination to suit the wishes of different riders, and further, that with all these advantages may, in construction, be combined with goose neck forms.
In the drawings,Figure 1 is a side view of devices embodying the invention. is a plan view of the post proper, other parts being'broken away. Fig. 3 is a section on the line 33, Fig. 1. tail views.
In the figures, A is the post proper, which is mortised through diametrically near its upper end and provided with an annular flange or shoulder B encircling the post at the bottom of the mortise and an axial set screw 0 entering the mortise from the upper end of the post.
Upon the shoulder rests a wedge shaped washer D which also encircles the post and which is milled upon its circumference to facilitate turning it upon the post as an axis. In the mortise, which is non-circular, fits the Figs. 4 and 5 are deend of a second member E, which may be considered as either a part of the saddle frame or one member of a two-part saddle post, the distinction being a matter of words rather than of principle since two-part posts, and saddles having an analogous member, are
common. This end is a straight bar which,
Fig. 2-
SerialNo-509,379. (No model.)
slides freely in the mortise and is fixed in any swing laterally out of the central plane of the machine, even when the set screw is loosened, either accidentally or for the adjustment of parts. This sliding of the bar is of the great est importance, for it not only afiords when desired a front and rear adjustment of the saddle without the possibility of lateral mis-- placement, but it renders the saddle support more or less yielding, and within very wide ]imits,'a result not attainable with other constructions when the goose neck,form is employed. When it is desired to change the inclination of the saddle, the set screw is loosened and the washer is rotated, a half turn giving a variation more than suliicient for ordinary requirements.
So far as the more general features are concerned, it is immaterial whether the member E be a straight bar corresponding to the L of ordinary posts, whether it be a part of the saddle, or whether it be so constructed as to serve as a spring; but as' the goose neck form of post has certain advantages, I have chosen dle post. In this form of post, the bends,-
which may be of various forms, integrally connect the end portion E with an upper straight arm E which carries a saddle of approved form.
I do not, then, wish to limit myself to the form shown, but
What I claim is i 1. Thecombination with a saddle post provided with a transverse perforation and a shoulder below the same, of a saddle supporting member having a straight portion sliding in said perforation to permit adjusting without tilting, a wedge shaped washer interposed between said member and said shoulder and means for clamping the three parts to form one rigid structure.
2. The combination with the post provided with the transverse non cylindrical perforamember against said washer and clamp all the tion and the shoulder below the same, of a parts into one rigid structure. 10 wedge shaped washer resting upon said shoul- In testimony whereof I affix my signature in der, a spring saddle supporting member havpresence of two witnesses.
