To all whom. it may concern.-

Be it known that I, FRANCIS H. RICHARDS, a citizen of the United States,residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bicycles,of which the following is a specification.

This invention relates to velocipedes, more especially to that class thereof generally designated as bicycles.

One of the objects of the invention is to provide an improved vehicle of this character constructed of separable members, whereby the same can be quickly and easily assembled and disassembled without interfering with or affecting the disposition or adjustment of the bearings, and thereby facilitate the transportation of such vehicle.

Another object of the invention is to provide an improved crank-hanger which can be quickly and easily assembled and disassembled relatively to the framing of the wheel.

In the drawings accompanying and forming a part of this invention, Figure 1 is aside elevation of this improved bicycle-framing assembled. Fig. 2 is a plan view of the rear portion of a bicycle with its wheel and a part of the framing shown in section. Fig. 3 is a view of the sprocket side of the cran k-hanger and adjacent parts, a part of the framing being shown in section and the sprocket-wheel being partly shown in dotted lines and broken away. Fig. 4 is a transverse sectional view taken in line a a, Fig. 3. Fig. 5 is an inside view of the crank-hanger end of one of the rear stays. Fig. 6 is a sectional view taken in line b b, Fig. 5. Fig. 7 is a sectional detail view, on an enlarged scale, of a part of the crank-shaft carrier. Fig. 8 illustrates the members of the crank-hanger disassembled. Figs. 9 to 20,inclusive,illustrate various members or parts of the wheel disassembled; and' Figs. 21, 22, and 23 illustrate a separable crank-hanger band or annular member.

The main object of this invention is to construct a bicycle which can be easily and quickly taken apart to facilitate the packing of the same for shipment or other transportation and in the assembling and disassemblingof which wheel the adjustment of the bearings need not be interfered with, so that the owner will have no difficulty in assembling the parts correctly and in a simple and thorough manner, and when so assembled said parts will form a rigid and durable structure.

As a preface to a further description of this improved velocipede, it will be understood that the invention is applicable to all kinds of bicycles, and hence does not necessarily have to be embodied in the construction of wheel shown herein.

Bicycles as ordinarily constructed have the framing thereof made as one rigid structure, this usually being accomplished by brazing the tubes in the coupling-lugs, so that it is necessary to provide large crates to accommodate the framing in order to properly ship the wheel, as only the handlebar, pedalcranks, seat, and wheels can be disassembled. In this improved bicycle, however, the framing is so constructed that the tubing thereof can be readily and quickly assembled and disassembled, and in one way of accomplishing this result, in the preferred form thereof herein shown and described, the head-lug 2,which in the structure shown herein is preferably rigid with the head 3, is adapted to receive one end ofa horizontal brace or tube 4,and for this purpose saidhead-lug is shown having a bifurcated part 2', into which one end of said brace extends, said members being coupled by a suitable fastening or clamping device 5, such as a bolt and nut, the bolt of which extends through the lug bifurcation and an apertured end of the brace, whereby the base is removably but at the same time firmly clamped in position. The seat-post lug 6 is also shown, preferably, rigidly secured to the seat-post '7 and is provided with two bifurcated parts 8 and 12, one of which is adapted to receive the other end of the horizontal brace or tube 4:, which is clamped therein preferably bya similar fastening device 9 to that just described. This seat-post lug is split in the usual way, whereby it is adapted to receive the seat-tube 10, carrying the usual saddle, such seat-tube being clamped therein bya suitable clam ping device 12, extending through the other bifurcated part 12 of said lug 6, at which point the upper end of the rear fork 13 is also secured. This rear fork in'the present structure is illustrated as formed of separable sides or members 13 and 13", each provided with a bearing-face 14:, adapted to be seated in a countersunk portion of the lug, whereby the shifting of the rear fork is prevented should the clamping device 12 work loose. Each rear fork side or member 13' and 13 respectively, is provided with a bifurcated lower end extending substantially at right angles thereto. Thelower head-lug 17 is preferably rigidly secured to the head and is shown in the drawings as having rigidly secured thereto the lower brace or tube 18, the opposite end of which tube carries one member of the crankhanger, shown herein as a band or casing of any suitable shape, but illustrated herein as an annular member 19, preferably fixedly secured to said brace and in one form thereof having an interiorly threaded socket 20, adapted to receive the threaded end 21 of the seat-post 7, whereby before the attachment of the horizontal brace 4c and the rear fork 13 such seat-post can be screwed into the threaded socket 20, and thus firmly secured at this point. This band or annular casing 19 may be, if desired, constructed of a plurality of separable members,shown herein as two members 19' and 19", one, as 19, rigid with the lower brace 18 and the other, as 19", rigid with the seat-post 7, or said members may be removably secured to said brace and post by clamping means or provided with threaded sockets similar to the socket 20 for the reception of the threaded end of said brace and seat-post. These member 19 and 19" may be secured together in any suitable way; but in the construction herein shown one is provided with a pair of slotted sockets 53, one at each end thereof, into which a pair of enlarged ends or heads 54 of the other member are adaped to fit, whereby when said members are in position they form a rigid structure. When this form of connection is used between the members of the annular band, the enlarged socket and head are preferably of less width than the band, whereby the edges of said band can fit into the annular recesses of the side disks or plates hereinafterdescribed.

The steering-stem 22, carried by the head 3, having the usual ball-bearings, is provided at its upper end with the usual handle-bar clamp 23 and cone-adjustment 24 and has at one side of its lower end, which projects below the head, a concave or semicircle recess 26. The crown 27 of the front fork 28 is pro Vided with a socket or recess 29, into which the end of said stem fits, said fork-crown having a transverse aperture or opening 30, through which a suitable fastening device 31, such as a cotter-pin, extends and into the semicircle recess of the stem, whereby the front fork is removably but rigidly secured in position. It will be understood that other fastening means may be used for removably coupling the fork and stem.

From the foregoing it will be seen that -on disassembling the framing for transportation or other purpose the head 3 and lower brace 18 may be one rigid structure, although it will be understood that such lower brace 18 may also be made detachable from the head in any suitable way, as by a threaded joint or by clamping means, if desired.

In the construction of ladies Wheels in order to have the framing of separable members it is simply necessary to have the upper curved brace detachable from the seat-post, orfrom both seat-post and head,if desired,and which can be readily accomplished in one way by clamping said curved brace in position at each end in a similar manner to that in which the horizontal tube 4 is secured.

The crank-hanger, which, as above stated, is constructed of separable members and has as one part thereof the band or annular casing 19, above mentioned, comprises a pair of side plates 32 and 33,conforming to the shape of such band, and hence preferably shown herein as disk-shaped, each plate being shown rigidly secured to and forming a part of each lower rear stay or tube 34:. Each of these plates is provided with an axial opening 35 and is preferably dished or bulged outward, and for this purpose is shown as concavo-convex, and has adjacent to its edge an annular recess or groove 36, adapted to receive the edge of the annular band 19, thereby substantiallyforming therewith a tongneandgroove joint. Carried by this crank-hanger, and which, to a certain extent, may be considered as forming a part thereof,is a crank-shaft carrier 37, shown as tubular and provided adjacent to one end with a stop-face, such as an adjusting collar or nut38, fixedly secured thereto, and adjacent to its other end with exterior threads 39, adapted to mesh with interior threads of one of the plates, as 32, whereby when the tubular carrier is in position the inner face of the adjusting-nut 38 will engage the outer face of the plate 33, while the threads 39 and 40, respectively, of the carrier 37 and plate 32 mesh with each other, whereby on turning the nut 38, and thereby the carrier, the plates will be firmly drawn and clamped in position, a suitable check or looking nut 41 being provided to also engage a part of the carrier-threads 39, thereby more securely to lock the plates in position.

From the above it will be seen that one part of the crank-hanger itself constitutes the fastening means for securing all the members of such crank-hanger together and this at one operation bymerely turning the carrier, as above set forth. It will also be noted that by this construction and organization of the crank-hanger a relatively large chamber is formed around the crank-shaft carrier, thereby permitting the side plates 32 and 33 to support the pedal-shaft carrier at points relatively a much greater distance apart than the distance between the plates at their peripheral edges, where they engage the annular band 19, so that said carrier is supported at points far enough apart to obtain horizontal stiffness, and the plates are made of sulficient diameter and of such shape, as concavoand fork side members together.

convex, to obtain vertical stiffness, so that by this construction of chamber around the carrier great stiffness and strength and a narrow tread with no increase in weight are made possible. Each stay member 34 is provided with a bifurcated end 34, extending in parallelism with the bifurcated end 16 of one rear fork side or member, so that when the two bifurcated ends are in juxtaposition, being held in such position by a projection carried by one of the bifurcated ends and shown herein as carried by the stay end and entering an aperture 43 of the fork side end, such members will be in position to receive the rear-wheel axle 55 in the usual manner and the chain-adjuster 44, which may be of any suit-able construction. The rear-wheel axle nuts 55 constitute not only the means for secnrin g the Wheel in position, but also a means for clamping the bifurcated ends of the stay This improved crank-hanger, it will readily be seen, may be used with Various kinds of crankshaft mechanism; but that shown supported thereby preferably comprises a pair of ballcups 45,0ne at each end of the crank-shaft carrier 37 and adapted to carry the usual ballbearings, and each cup having a flanged end 46 engaging the outer end of said bracket 37. The crank-shaft 47, which carries the pedalcranks 47' and 47, one at each end thereof, is shown provided adjacent to one end with a series of exterior threads 48 for the reception of the usual adjusting-cone 49, the removable sprocket-wheel 50,-and the lock-nut 51, and adjacent to its opposite end with threads 48 for the reception of the usual adjusting-cone 49' and lock-nut 51.

From the foregoing it will be seen that on the removal of the pedal-crank 47 and the lock-nut 41 the opposite crank 47", sprocketwheel 50, and'cran k-shaftcarrier 37, together I with the bearings and adjusting-cones, can

be unscrewed and completely removed from the plates 32 and 33 withoutinterfering with or disturbing the adjustment of such bearings or the other parts of the crank-shaft mechanism and that,if desired, the side plates can then be detached by removing the driving-Wheel in the usual way, whereupon the stays can be quickly detached from the rear fork..

In conclusion it will be seen that when it is desired to ship or otherwise transport the wheel it is simply necessary after the removal of the wheels, the seat, and the handle-bar to unclamp the upper horizontal tube 4 from the head and seat-post, remove the cotter-pin 31 from the front fork, the clamping device 12 at the upper end of the rear fork, unscrew the seat-post 7 from the crank-hanger band 20, and then detach the pedal-crank 47 and lock-nut 41, whereby all the parts can be quickly disassembled in a similar manner, if desired, to that shown in Figs. 9 to 20, and then readily packed in a trunk or other suitable means for transportation, and this without disturbing the position or adjustment of the bearings, so that when it is desired to assemble the parts of the wheel this can 'be quickly done without the necessity of working with the bearings to have them in proper position.
