SPECIFICATION forming part of Letters Patent No. 623,421, dated April 18, 1899.

Application filed January '7, 1899. Serial No. 701,496- (No modeLl To all whom it may concern:

Be it known that LBARTHOLOMEW PEISEN, a citizen of the United States, residing at Eldora, in the county of Hardin and State of Iowa, have invented certain new and useful Improvements in Bicycle-Supports; and Ido hereby declare the following to be afull,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.

This invention relates to improvements in bicycle-supports and its object is to provide a support which can be readily and conveniently adjusted for application to bicycleframes of different sizes and embodies simple and effective means for automatically projecting and spreading the supporting-legs, together with improved devices for closing and folding the legs and also holding the same in a closed position.

A further object is to provide an improved construction of casing,a spring-actuated shaft inclosed therein and acting on the legs to project them, a pivoted lever for closing the legs against the tension of said spring mechanism through the medium of suitable connections and designed to act also as a brake to prevent forward movement of the bicycle, and a holder adapted to be opened and closed automatically to engage and release the legs when said connections are operated.

ith these and other objects in view the invention consists in certain novel features of construction, combination, and arrangement of parts, which will be hereinafter more fully described, and particularly pointed out in the appended claims. v

In the accompanying drawings, forming a part of this specification,Figure 1 is a fragmentary perspective view of a bicycle supported in an upright position by means of my invention. Fig. is a fragmentaryside elevational view of a bicycle, showing the parts of the support closed. Fig. 3 is a top plan View of the casing with cover removed,showingthe position of the parts when the legs are projected. Fig. at is a similar view showing the position of the parts when the legs are closed or folded up. Fig. 5 is a longitudinal sectional view of the casing with the parts arranged as shown in Fig. 4. Fig. 6 is a cross-sectional view thereof with the parts arranged as shown in Fig. 3.

Fig. 8 is a front perspective view showing the pivoted supporting members and confining-plate of the holder or rest detached, but in their relative positions. Fig. 9 is a detail perspective view of the pivoted lever and connectinglinks. Fig. 10 is a detail sectional view of the head-clamp and lever. Fig. 11 is a detail sectional view of the clips shown in Figs. 7 and 8. supporting-legs.

Referring now more particularly to the drawings, wherein like reference-numerals designate corresponding parts throughout the several views, 1 represents the lower main tube of a bicycle-frame, and 2 a casing closed at top by a cover 3, having its upper surface concaved to closely embrace the said tube and provided with clips l, whereby it is con nected therewith a short distance in advance of the crank-hanger. The casing is provided with a curved or segment-shaped bottom 5, provided on opposite sides of its center with substantially S-shaped slots 6, extending longitudinally thereof, and the front ends of these slots are curved inwardly toward each other, while their rear ends are curved outwardly or diverge toward the sides of the easing, as shown clearly in Figs. 3 and 4.

Arranged within the casing is an oscillatory shaft or arbor 7, provided with journals or trunnions j ourn aled in the side walls thereof or in suitable bearings secured upon the inner sides thereof. This shaft or arbor is held under tension by strap or ribbon springs 8, provided at their front ends with coils 9, embracing the opposite ends of said shaft and suitably secured thereto and having their opposite ends 10 extended rearwardly and passed over a post or cross-bar 11', connecting the sides of the casing, so that said free ends will bear against the rear walls of the casing and be held against displacement. Arranged also in the casing are a pair of substantially U-shaped oscillatory frames 12, having their outer arms 13 extended and rigidly connected with the shaft or arbor and their inner arms provided with ears lei, connected to similar ears projecting from a tubular head or sleeve 15, rigidly secured to the central portion of Fig. 12 is a similar view of one of the the shaft. To these cars 14 are pivoted the rear ends of a pair of supporting-legs 16, which project through and are adapted to move in the said curved slots 6 and also to slide laterally in slots 13, formed in the front ends or cross-bars of the U -shaped oscillatory frames. These legs maybe either tubular or solid, but in the present instance are shown as provided in their outer ends with threaded Sockets 1'? for the reception of threaded rods 18, which are adapted to be adjusted to lengthen the legs through the medium of milled thumb-nuts 19 and are provided at their outer ends with knobs or heads 20, having spurs or projections adapted to engage the pavement or ground to prevent the legs from slipping. The strap-springs 8 normally serve to exert a backward pull or tension on the shaft or arbor, which causes it to turn forwardly in the direction of the arrow shown in Fig. 5, and as the U-shaped frame to which the legs are pivotally connected is rigidly secured thereto it will be seen that the legs will be drawn downwardly and outwardly and caused to traverse the slots 6 and that they will be guided by said slots and caused to diverge or spread outwardly, so as to bear upon the surface of the street or ground on opposite sides of'the frame of the bicycle, and

thus afford a firm and stable support for the latter. It will also be seen that when the legs are fully projected they incline forwardly, and thus tend to hold the bicycle against casual movement in a forward direction.

The U-shaped oscillatory frames are connected at their lower ends by a cross bar or rod 21, and mounted on this rod between the frames is a slotted cam or eccentric link 22.

The outer surface of this link is grooved or recessed to receive the rear hooked end 23 of a flexible rod 2%, which projects outwardly through an opening in the front of the casing and is adapted to slide over a pulley 25, journaled therein. This rod is threaded from a point about midway of its length to its outer end, and this threaded portion projects through an int-ernally-threaded tube 26, supported at its front end by a clip 27, engaging the lower main tube 1 of the frame a short distance in rear of the head-tube thereof. The base portion of this clip is provided with a guide-opening 28, in which the tube is slidably mounted, and is provided at its rear with a detachable confining-plate 30, having forwardly-projecting stops 31 at its ends. Mounted on the tube in rear of said clip is a rest or holder, which supports the free ends of the legs and consists of two

members

32 and 33, concaved to form shoulders 32 and 33', upon which the legs are adapted to rest, and provided with ears 3&, by which they are pivotally mounted on the tube to move toward and from each other. The said members are also provided with stop-lugs 35, adapted to engage the stops 31 to limit their outward movement and also to engage the confiningplate 30, by which they are held connected thumb-nut 38, whereby it may be adjusted thereon. This adjusting device bears against the under side of the lower main tube 1 of the frame and is provided at opposite sides with ears 39, to which the rear ends of curved connecting-links40arepivoted. Totheheadtube of the bicycle-frame is connected a clamp 41, provided with pivoted clamping-arms 42, adapted to engage the same, and to the lower end of this clamp is pivoted a lever 43, provided at one end with curved ears or projections 44, to which the front ends of the said link are pivotally connected. The lever is also provided with a threaded guide and socket for the reception of a threaded shank 45, carrying at its outer end a shoe 47 and adapted to be adjusted through the medium of a milled thumb-nut 48.

In Fig. 2 of the drawings I have shown the parts of the support closed or folded up, and from this it will be seen that the pivoted lever is turned to bear against the front surface of the head-clamp. lVhen it is desired to employ the support for supporting the bicycle when the latter is not in use, the pivoted lever is thrown downward and the threaded flexible rod and the guide-tube mounted thereon are forced rearwardly, thus allowing the strap-springs 8, acting on the shaft to which the U-shaped frame and supporting-legs are connected, to force the latter downwardly and rearwardly, whereby the legs are also forced downwardly and are caused bythe contour of the slots in the bottom of the casing to spread outwardly as they are projected into operative position. lVhen thus projected, the legs stand at aslight forward incline, and thus tend to hold the bicycle against casual forward movement,while at the same time affording a stable support to prevent the same from tilting over. The shoe of the pivoted lever when thrown down in the manner describedalso serves to bear upon the tire of the front wheel and act as a the legs being guided by the slots until they are closed together and extend parallel with each other and with the tube 526. The forward movement of the tube also causes the trip or striker to spread the two members of the rest or holder apart, so that they will move under and support the legs. The backward movement of the tube which takes place when the pivoted lever is thrown down to project the legs in the manner heretofore de scribed withdraws the trip or striker from engagement with the pivoted members of the rest or holder, which close together by gravity and release the legs. It will be understood from the foregoing description that the connection between the pivoted lever and U-shaped framesviz., the flexible rod and tubeserves when said lever is thrown up to close the parts against the tension of the springs on the shaft or arbor in the casing and also release the said legs when the lever is thrown down, so that the cross-bar 21, connecting the oscillatory frames, may move freely in the slot of the cam or eccentric link, and thus allow the springs to force the shaft, frame, and legs downwardly.

The tube 26, to which the links are connected, may be readilyand conveniently adjusted when desired to adapt the support for application to bicycle-frames of different lengths.

It will of course be understood that changes in the form, proportions, and minor details of construction may be made within the scope of the invention withoutdeparting from the nature orspirit of the invention or sacrificing any of the advantages thereof.
