DANIEL WV. ALBRIGHT, OF CEDAR RAPIDS, IOIVA.

BICYCLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 564,134, dated July 14, 1896.

Application filed January 7, 1895. Serial No. 584,163. (No model.)

To aZZ whom it may concern.-

Be it known that I, DANIEL W. ALBRIGHT, a citizen of the United States, residing at Oedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Bicycle-Supports; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to produce a bicycle-support which may be attached to awheel without altering the same and which when attached will present a neatappearance.

A further object of my in vention is the production of a support of such construction and arrangement with respect to the bicycle that it may be readily released by the rider without dis-mounting and which when so released will automatically assume its proper position for supporting the wheel.

In the accompanying drawings, Figure I is a side elevation of a bicycle with my support attached and in its normal position, the supporting position of the same being shown in dotted lines. Fig. II is a rear elevation of the bicycle, showing the support swung down to the supporting position. Fig. III is a side elevation, on an enlarged scale, of the support and mechanism for attaching it to the cycleframe. Fig. IV is a View of the head of the support at right angles to the position shown in Fig. III. Fig. V is avertical longitudinal. section of Fig. IV. Fig. VI is a section on the line 00 0c of Fig. III. Fig. VII is a detail view of the retaining-hook D and its securing mechanism. Fig. VIII is a detail view of a modified form of the lower ends of the legs of the support.

Referring to the letters on the drawings, A indicates the rear brace-rod of the bicycle, extending, as usual, from the upper rear angle of the frame to the rear axle, and B indicates a clamping-collar provided with an ordinary clamping-screw G and longitudinally adj L st-- able upon the brace-rod A.

The collar B, for a purpose hereinafter apparent, is secured to the brace-rod in such position as to be substantially in vertical alinement with the axle of the rear wheel,

and its face upon the opposite side of the frame from the screw G is angled in such manner as to have a plane a parallel to the brace-rod and a second plane I) at a considerable angle, as illustratedin Fig. III, against which is pivotally retained the correspondingly-angled head 0 of the support, as by a stud E, revolubly mounted in the collar and provided with a squared head E. The head E projects beyond the angled face of the collar and enters an inclined-sided aperture in the head 0 of the support in order to accommodate a slight rocking or tilting of the support-head upon a pintle II, which passes through the head 0 and the head E of the stud at right angles to the latter.

The purpose of the abutting angled faces of the support head and collar is to enable the support when in the normal position to lie parallel with and in close proximity to the brace A and to compel it when released and thrown backward to assume a position at a considerable angle to the brace for the purpose of constituting a secure support and to bring the center of gravity of the Wheel a considerable distance to one sideof the wheel.

The angled face of the support-head is produced by simply beveling its extremity beyond the pintle H, so that in either position of the support the side of the head parallel to the supporting-legs lies flat against one of the planes of the angled face of the collar and the direction of the support in consequence depends upon the plane against which the head below the bevel abuts. Not only is this cam action efficient in automatically directing the position of the legs with respect to the wheel, but it also constitutes a locking device, inasmuch as the head 0 must have slight lateral movement during the reversal of the support. It is to accommodate this movement that the pintle connection between the stud and the support-head is employed, the parts being made sufficiently loose to acmodate this slight yielding action, but not to such a degree as to overcome all resistance.

The support may be made of a single rod, but I prefer to employ the construction shown in the drawings, in which a leg 0 is hinged, as by a pintle I, within a recess in the head 0, from which latter extends a rigid leg 0. p

The legs 0 and G are preferably made semicylindrical and are provided in their adjacent faces with corresponding longitudinal recesses 0 within one of which is terminally secured a leaf-sprin g F, the tendency of which is to force the legs apart, but which, when they are held together, as by the clip-hook D,is entirely concealed. Theclip-hook D referred to is adjustable by means of a split collar and clamping-screw G upon the brace A, and consists of a leaf-spring forming a substantially cylindrical portion and a clip end. The hook is preferably located at the upper extremity of the brace A, and constitutes locking and releasing mechanism for the support immediately under the seat of the bicycle within easy reach of the rider.

By the construction hereinbefore described I am enabled to produce a support for bicycles which is normally carried close against the rear brace of a bicycle and which when released by the rider by forcing its end from the hook I) automatically assumes a position at a considerable angle with respect to the wheel and which by the same act is automatically converted into a two-legged supporting-frame.

The purpose of the location of the supporting-collar in vertical alinenlent with the rear axle is to locate it in alinement with the point from which the wheel swings in the event of the front wheel being turned by accident or design and thus reducing to the minimum the liability of overthrowing the bicycle in the event of its being jostled.

I do not desire to limit myself to the details of construction herein shown and described, but reserve to myself the right to vary and modify the same at will within the scope of my invention.

hat I claim isspect to the stud pivotally securing the support to the squared head of the stud, substantially as specified.

2. In a support for bicycles, the combination with a supporting-collar, of a support pivoted thereto, said collar having two separate and distinct faces upon the opposite sides of the pivot and at an angle with respect to each other, the line of juncture of the faces extending entirely across the collar and diametrical with respect to the pivot, and said support pivoted to the supporting-collar being provided with an angled face corresponding to and adapted to cooperate with the supporting-collar, substantially as set forth.

3. In a support for bicycles, the combination with a supporting-collar having two. separate and distinct faces and at an angle to each other, of a revoluble stud projecting from the collar and provided with a squared end, a support provided with an angle end, and with a square, inclined-sided aperture, and a pintle passing transversely through the support and the squared head of the stud, sub stantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

DANIEL XV. ALBRIGHT.
