FERRAUD GIACINTO, OF NEV YORK, N. Y.

BICYCLE-STAND.

SPECIFICATION forming part of Letters Patent No. 569,493, dated October 13, 1896.

Application filed October 3l, 1895. Serial No. 567,540. (No model.)

To all whom t may concern,.-

Be it known that I, FERRAUD GIACINTO, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bicycle-Stands; 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.

rlhe stand or support for safety-bicycles hereinafter described is designed more 'especially as an improvement on the automatic stand which forms the subject of an earlier application for Letters Patent tiled by me on the 8th of July, 1895, Serial No. 555,257.

The object of this improvement is to provide improved means for bracing the legs of the tripod when they are unfolded for use, so as to relieve the pivotal arbor or bolt from a considerable portion of the strain.

A further object of the invention is to simplify and cheapen the construction and to adapt the device to be more expeditiously ap'- plied to the frame of a bicycle.

YVith these ends in view my invention consists in the novel combination of devices and in the construction and arrangement of parts, which will be hereinafter fully described and claimed.

I have illustrated my improvements in the accompanying drawings, forming a part of this specification, in which- Figure l is a side elevation, and Fig. 2 is an elevation looking at the rear of the improved bracket which supports the pivotal arbor orbolt that sustains the legs. Fig. 3 is a plan view, with the bracket partly broken away, showing the legs which form the tripod folded parallel to each other. Fig. el is a detail view of one of the legs. Figs. 5 and 6 are detail sectional views of a simplified construction of the leg-holder.

Likeletters of reference denote corresponding parts in all the iigures of the drawings.

As in my prior application, to which reference has been made, my bicycle-stand comprises a bracket, a leg-holder, and a tripod. The bracket is adapted to be applied to the bicycle-frame near the crank-shaft bearing,

and the leg-holder is fastened on said bicycleframe at a suitable distance from the bracket, so as to receive the points or free ends of the legs when the latter are folded together and turned up into engagement with the legholder to enable the latter to retain the legs in their folded position when the bicycle is in use. The legs forming the tripod are connected in a peculiar way to the bracket to adapt them to be swung down and spread laterally when the tripod is to be used to sustain the bicycle in a raised position, and two springs are used to throw the legs in their opened spread portions, one of said springs being connected to the central leg or to the arbor, so as to turn said'central leg to a position back of the two side legs, while the other spring has two arms which are connected to the side legs and which spring-arms operate, when the legs are released from the leg-holder, to spread the side legs laterally with respect to the central leg.

As the present improvements relate especially to the mode of hanging the tripod-legs, the construction of the bracket, and the construction of the leg-holder, I have not thought it essential to illustrate the manner of applying the stand to the bicycle-frame nor to show the springs by which the legs are turned down and spread automatically when released from the leg-holder, because these features will be readily understood by reference to the specification and drawing of my other application referred to.

A designates the bracket in Figs. l and 2. This bracket consists of the side plates a, arranged parallel to each other, and at their front ends the side plates are extended upwardly, as at a', and they are flanged at a2. A clamp B is provided to fasten the bracket to the bicycle-frame, and it consists of two curved sections b b', the lower section b hav-` ing its flanged edges fitted to the lower side of lthe flanged edges a2 of the bracket, while the other or upper clamp-section b has its flanged edges iitted down upon the top of the fianged edges a2 of the bracket, as will be understood by reference to Fig. 2. The lianged clamp-sections b b and the flanged edges a2 of the bracket are rigidly held together and clamped on the bicycle-frame by means of the bolts or set-screws c c, which are passed through the overlapping flanges of the clamp and the bracket- It will be noted that I provide a sectional clamp which is adapted to snugly embrace the bar of the bicycle-frame and that the sections of the clamp are drawn together by the same bolts or screws which couple the bracket and clamp together.

The rear ends of the side plates ct ct of the bracket are bent or iianged inwardly toward each other, as at d d, (indicated by dotted lines in Fig. 2,) and said rear ends of the plates o a are joined together and braced by means of the plate D, which overlaps the iianges d and is riveted or otherwise rigidly united to the angcs d, as at d", whereby the bracket is materially strengthened. The plate or web D, which connects the bracket-plates a, is tapered and extended below the bracket-plates, as shown by Figs. l and 2, and in the lower edge of this plate or web is produced the notch Y e. The extended lower edge of the transverse plate or web D lies in the path of the central leg of the tripod, and when the tripod-legs are released from the leg-holder and they are swung down to their open ed positions the central leg of the tripod swings back to and rests in the notch e of the web or plate D, whereby the notched web or plate serves to hold the central tripod-leg against edgewise or lateral play. The bracket-plates a a are further provided with the downwardly-projecting arms Y ff, which are formed at intermediate points of the length of said plates a and preferably just in rear of the pivotal arbor or bolt, and these arms f j are provided with the inclined ledges or shoulders g g. These inclined ledges or shoulders lie within or on the opposing faces of the bracket-plates, (see the full-line representation in Fig 2 and the dotted line shown in Fig. 1,) and against these inclined ledges are adapted to bear the side legs of the tripod when the legs are unfolded and the side legs are spread laterally, so that the ledges or ilan ges serve to brace the side tripod-legs and relieve to some extent the strain on the pivotal bolt or arbor.

In Figs. 3 and 4l have illustrated the tripod and one of the legs thereof to show the improved mode of connecting the side legs E E to the pivotal bolt in a manner to permit said side legs to be moved laterally by the doublearmed spring, to which reference has heretofore been made. The pivotal bolt or arbor G is loosely mounted in the side plates ct d of the bracket to turn or rock therein under the influence of a spring, such as the helical spring shown in my other application, and to this arbor is rigidly fastened, as by a setscrew, the central leg F of the tripod. This central leg F is thus adapted to turn with the pivotal bolt, and when the tripod is released from the leg-holder said central leg is adapted to swing back against the web D and seat itlnmy former self in the notch e thereof.

bicycle-stand the side legs were provided with beveled heads fitted loosely in the pivotal arbor, so as to turn thereon both axially and laterally; but in my present improvement the side legs are articulated to play or swing laterally, and they are positively connected by intermediate devices with the arbor or bolt. The side legs E E are rigid with the knuckles H H, which are arranged between the legs and the pivotal arbor or bolt, and said knuckles are jointed to secure the lateral play of the legs E E. Each knuckle consists of two sections 7L h, one of which is forked or bifurcated at z' to receive the tenon t" on the other section, and the ltwo sections are coupled together bya pin i", which passes through the forked end and the tenon It. The tenon-formed end of the section h, with which the leg E is rigid, has the shoulders j, and the forked ends of the section h are beveled or inclined, as at j', to enable the section h and the leg attached thereto to have the desired lateral movement,which lateral movement is limited by the shouldersj on section h, abutting against the beveled or chamfered ends j of the section 7L'. The knuckle H is connected to the arbor or bolt G by means of the clip l, which fits around the arbor and has its ends brought together upon and fastened to the section h/ of the knuckle. It will be noted that the clips I, which connect the side legsto the bolt or arbor, are free to turn on the bolt in order to lower or raise the side legs, but said clips do not have any lateral loose play on the bolt. The lateral movement of the side legs is provided for in the articulated knuckles H, which also serve t0 limit the lateral play of the legs.- The sections h h ofv the knuckles are provided with the lugs la 7c, which are adapted to bear upon the inclined shoulder or shoulders f of the bracket. As the upper or right-hand leg E .must move to the right and the lower or leftparts ZZ' and at the top and bottom sides,`

through which lapped portions are passed screws or other suitable vdevices to hold the sections J J together. The curved parts Z l of the two sections are adapted to embrace the bicycle-frame and form the clamp by which the leg-holder is held on the said frame, and the curved parts Z. Z of the two sections J J form a thimble in which is fitted the slidable sleeve K. This sleeve 'K is surrounded by a spiral spring K', which is also inclosed within the thimble formed by the parts Z Z of the sections J J, and the thimble is guided in openings in two heads L L', secured to the edges lloo IIO

of the sections J J, around the curved parts Z Z thereof. One end of the spiral spring bears against one of the heads L' and the other end of said spring bears against a pin Z2, se'- cured to the sleeve, so as to impel the sleeve rearward in position to hold the legs E E F when they are folded. On the front end of the sleeve is secured the finger-piece M, by which the endwise movement of the sleeve in one direction is limited, and which aords a convenient means for pulling the sleeve forward to release the tripod-legs, and said sleeve is further provided with a iiared mouthpiece N, which is fastened to the rear end of the sleeve and in which the points of the tripodlegs are adapted to fit when said legs are folded together and turned up to engage with and be held by the tripod.

The plates J J of the leg-holder can be cheaply made by striking them up from a plate of sheet metal, and the parts of the legholder can be readily assembled together.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a stand or support for safety-bicycles, the bracket havinga seat such as ein combination with tripod-legs, one of which is adapted to abut against and fit within the seat e of said bracket, substantially as described.

In a stand or support for safety-bicycles, the bracket provided with the transverse Web D having a notched seat c in the path of the central tripod-leg, combined with said tripodlegs which are hung in the bracket in a manner to permit the central leg thereof to fit in the seat e and be held therein against lateral play, substantially as described.

3. In a stand or support for safety-bicycles, the combination with a bracket, of a pivotal bolt or arbor, a central leg mounted on said arbor or bolt to swing to an inclined position backwardly with relation to the bolt, andthe side legs connected with said arbor to Swing laterally on diverging lines; the connection between the side legs and the arbor being effected by articulated knuckles each having a pivotal joint at an intermediate point of its length, whereby the side legs may spread laterally Without riding against the head of the central leg, substantially as described.

4. In a stand or support for safety-bicycles, the combination with a bracket, a pivotal bolt or arbor, and a central leg, of the side legs, and the knuckles connected by clips to the bolt or arbor and having the sections 7L; h' coupled together by joints which limit the lateral movement of the legs, substantially as and for the purposes described.

5. In a stand or support for safety-bicycles, the bracket having the inclined shoulders or ledges g, g, in combination with the legs E, E, hung to the bracket to have a limitedlateral play and adapted to bear against the ledges or shoulders, for the purposes described, substantially as set forth.

In testimony whereof I affix my signature in presence of 4two witnesses.
