AMBROGIO ENRICO CONTI, OF GENOA, ITALY.
SPECIFICATION forming part of Letters Patent No. 640,631, dated January 2, 1900.
Application filed 3111162, 1899- Serial No. 719,095- (No model.)
To all whom it may concern:
Be it known that I, AMBROGIO ENRIOO CONTI, a subject of the King of Italy, residing at Genoa, Italy, have invented certain new and useful Improvements in Bicycle- Supports, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.
My invention relates to an improvement in bicycle-holders which may be adjusted to fit different kinds and varieties of bicycles. The said support can be fixed as well as moved upon its wheels or, if it is desired, may be folded up flat and packed by the side of the bicycle.
In order to better understand the nature of the invention, attention is called to the accompanying drawings, in which- Figure 1 shows a side view of the bicyclesupport; Fig. 2, a back view of the same; Fig. 3, a perspective view, and Fig. 4 a side view, of the support folded.
In all the several views like parts are indicated by the same letters of reference.
Broadly speaking, the device consists of a main frame and a secondary frame attached thereto.
The main frame is rigid, being constructed of two fiat bars a, running approximately parallel to each other at the upper ends, but diverging for one-third of their length toward the lower end I). These two bars are secured together by means of a plate 0 riveted thereto, and they are further strengthened by the reinforcing-struts (l, riveted to the plate a and to the bars a, near their lower extremities. The lower ends of the side bars (L are connected together by means of an axle g, carrying the two wheels f thereon and surrounded by the spiral spring e. The spiral spring expands with a certain amount of pressure against the wheels f and serves to retain them in a fixed position, although without preventing the rotation of the latter.
The auxiliary frame is as follows: A rear brace 41 is formed of two parallel bars fixed at their upper extremities to a flat cross-bar h, which is pivoted between the side bars a. The rear extremity of the brace i is provided with a wheel j, mounted upon a suitable axle. The brace 11 is held at any desired angle in relation to the main frame by means of the secondary brace Z. The latter is formed of two parallel bars, the extremities of which are mounted upon the axle g. The head is flattened and is provided with a plurality of slots adapted to engage with the axle sup porting the wheel 3'. By this means the angle, the brace i, and the main frame a may be regulated at will.
The supporting-brackets m are rigidly attached to the upper extremities of the braces 'i and are supported thereby. The bars 2', sliding upon the cross-bar it, may be separated to some extent, and the supporting.
brackets may be separated accordingly.
In addition to the supporting-brackets m I propose to use a locking device. (Shown more clearly in Fig. 3.) This consists of a V- shaped frame a, pivoted to the side bars a of the main frame and carrying a hook o, having a screw -threaded shank which passes through an opening in the apex of the forkpiece 02 and is provided with a thumb-screw p, by means of which it may be adjusted with relation to the frame.
Attached to the upper portion of the main frame a is a double-forked hinged piece q, formed of two thin bars joined at '1', but separated at s and there secured to the side bars.
All the parts of the bicycle-support are preferably'made of thin iron bars.
According to the form and size of the bi cycle-frame to be placed on the support the position of the brace t' must be regulated and the angle a between it and the main frame more or less opened.
The bicycle is supported by resting its bot tom bracket upon the two supporting-brack ets m, and these latter being movable side= wise they can support any shape of frame. The bicycle is further supported by its ante rior tube resting in the openings of the fork q.
To more firmly secure the bicycle to the frame for repairing or for other purposes, the hook o is adjusted around the under bar of the bicycle and sufficient tension applied to the nut to hold the bicycle firmly in place. The hook being once adjusted for any bicycle need not be unscrewed or readjusted every time the bicycle is put on or taken off, for this operation is effected simply by pulling up or pushing down the V-shaped forked piece at to the proper degree, the hook 0 being turned at a right angle to allow it to escape the frame of the bicycle. The double fork q serves to grasp the front wheel of the bicycle and to rigidly hold the front forksin position. When it is desired to support the bicycle upon the frame and still allow the front forks to be firm, the fork q may be lowered.
It will 7 be seen that this bicycle-support gives free access to all parts of the bicycle, a circumstance of great convenience in repairing and for the inspection of the machine.
Another advantage consists in the fact that the auxiliary frame can be folded inside the main frame, when the Whole stand will assume the appearance shown in Fig. 4.. Nhen thus folded up, it can be easily carried by hand or at the side of the bicycle without any inconvenience whatever.
Having particularly described and ascertained the nature of my invention, what I claim as new and useful therein, and desire to secure by Letters Patent, is-
1. An adjustable folding bicycle-support,
consisting of a trestle having three points of support provided with rollers thereon, the adjustable sliding brackets m for the principal support of the bicycle, the fork n carrying alock-hook 0 thereon, and the fork q securing the front wheel, substantially as set forth.
2. An adjustable folding bicycle-support, consisting of a trestle having three points of support provided with the forks b, carrying rollers f, f, and the adjustable brace ihinged to the forks, a spiral spring 6 to act upon the rollers f, f, substantially as set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
