SPECIFICATION forming part of Letters Patent No. 385,847, dated d'uly 10, 1888.

Application filed December 3, 1887. Serial No. 256,845. (No model.)

To aZZ 1071/0111, it may concern: tion, takenin connection with the accompany- Be it known that I, Janus S. COPELAND, of ing drawings. Hartford, in the county of Hartford and State \Vhile I show and describe my improve of Connecticut, have invented certain new and ments as applied in one form of a tricycle, it 5 useful Improvements in Velocipedes, of which will be obvious to any skilled in the art that 55 the following is a specification. they are applicable in other forms of tricyeles The object-of my present improvements is to and in other velocipedes besides tricycles, and produce alight, efficient, economical, simple, I do not intend to limit myself in pointing out easy-running, and convenient tricycle; and my invention and what I now consider the also to produce a tricycle without along main best form of embodying my improvements to 6 axle and its intricate and cumbersome balthe precise form or forms and arrangements ance-gear, but with a single main drivingherein shown and described.

Fig. 6 in the details of velocipede construction,which shows in perspective one of the dwarf steerwill be apparent from the following descriping-heads. Fig. 8 shows parts of the second 10:

ary frame and steering devices in vertical longitudinal section. Figs. 9 to 16, inclusive, show in perspective details of my improved devices enlarged.

A is the driving wheel, having a fixed axle, A. I

B B are guiding-wheels arranged abreast, having axles B B, on which, as I prefer to make them, they are free toturn, and, as I prefer to arrange these wheels, the two guidingwheels are in front and a sufficient distance apart at their remotest for stability of the machine, and the driving-wheel A is arranged to follow and track midway between. I connect rigidly with the axle of each of these steeringwheels a dwarf steering-head, B", on the inside by means of the lug B", and as this dwarf steeringhead is sufficiently described in Letters Patent of A. E. Wallace, No. 312,411, I need not further describe it, except to say that it affords a swivel or spindle center joint with the frame, and I do not limit myself to the use of this kind of steering-joint.

In constructing the main frame of this improved velocipede I use a vertical or nearly vertical tubular pillar, O, and a horizontal or nearly horizontal tubular reach, 0, and a tubular lower fork, O 0", and a tubular upper fork, G G, andI connect the pillar Owith the reach 0 and the lower fork-arms, 0 O, by means of a forged bracket, 0, to which they are brazed, and I connect the pillarGwith the upper forkarms, 0 O, by means of a forged bracket, 0 E, to which they are brazed, and I connect the rear ends of the fork-arms C G on each side the driving-wheels by means of a forged bracket, 0, which affords a bearing for or a connection with a bearing for the main axle A. In the brackets c c, I make bearings and conical seats concentric with the pillar C for a steering-post, and in the bracket E*, I make a vertical bearing for a scat-rod, and on the bracket 0, I make two lugs for attachment of a brake-lever spoon, and to the forward end of the reach 0, I connect by brazing a bracket, '0, having two branches, 0 c, with slots 0 c on circular arcs concentric with thehinge-lug 0 connected with the branches 0 and themain part of the bracket 0 by a middle arm, a", and eross-arms C 0 extending to the limit-lugs 0 0. D D are tubular transverse reaches, each connected at one end to aspindle, d, in the dwarf steering'head B and constructed at the other end with an arm, D or D". These arms D D are made or attached in reverse form to the arm D has the hingelug (1 corresponding to the similar log, (P. E is the saddle, and E a saddle'spring. E is a bent saddle-supporting rod, having one part nearly horizontal and the other part nearly vertically held in the bracket E adj ustably for different Vertical heights of the saddles and secured by means of a setscrew or otherwise.

F F are pedals.

F F are brackets connected to ashaft or axle, F, which is held by suitable bearings in an adjustable bracket, F on the reach 0'. Connected with the same shaft-,F,is a sprocket-wheel, F", which latter is connected by means of a driving-chain, F with a sprocketwheel, F, rigidly connected with the drivingwheel A. This bracket F I prefer to make to inclose the reach 0 and to have the split lug and screwf on the upper side, and to it on the lower side are connected by two small bolts, f f the bearing-lugsf f of the crank-shaft.

G G are the steering-handles, and G G are handle-bars, which are connected together and to a steering-post by means of a lug, '9 (shown fully in Fig. 13,)arranged abaft the middle of the machine and beneath the saddle E. From this lug they are bent or curved backward, outward, upward, and forward, as shown in the drawings, so as neither to be in front of the rider nor to interfere with the free action of the riders thighs, and also to bring the handles to proper fore-and-aft and lateral positions.

Gr is a steering-post extending nearly vertically through the pillar G and the brackets c and c, in which it has its bearings and is adjustably seated by means of the bearing-rings G G. I prefer to make these btearingrings,

as shown in Figs. 14 and 15, with split lugs g 9 which may be tightened for securing these rings in position on the steering-post adjustably, and also to make them with a conical surface at one end to fit into conical seats in the brackets 0 0. By loosening these bearingrings Gr Gr the steering-post G may be adjusted in height to suit the requirements of the rider for the height of handle-bars, and

when the steering-post is adjusted to the proper height, first the ring G" is set, holding it there, and the ring G is brought up and adjusted so as to makea proper and free hearing, so that the steering-post may be revolved about its axis easily and without rattle, the conical seats and faces of the bearings serving to prevent side shake and to make better bearings. I construct thering G with an arm, G which, when the ring G is set upon the steering-post, will of course turn with the latter, and which terminates in a wrist, 9 in which is jointed one end of the steering-rod G. The other end of the steering-rod G terminates in a wrist, g, jointed to the arm G of a bellcrank lever having a hinge-joint, 9 about a fulcrum-bolt, 7c,- and G is the other arm of bell-crank lever carryingthe hinge-boltL. On this bolt are the conical seating-rings Z Z, secured by a nut, L, which affords bearings in corresponding conical seats in the wrists g g of the transverse steering-rods G G. These transverse steering-rods G G are each connected to one of the guiding-wheels by a wrist, g, hinged at the end of the lever-arm 13', connected with the steering-head 13 before described. The construction and arrangement of these parts are such that when the steering- ICC handles are moved through a. small are about I the center of the steering-post the arm G is swung forward or backward, moving the longitudinal steering rod G back and forth through a short distance, and so through the bell-crank lever G G pushing one of the transverse steering-rods G" as itpnlls the other, and so deflects each of the guiding-wheels simultaneously and equally.

H is a brake-lever,fulcrumed at H upon one of the steering-handles and jointed to a connectingrod, H which is jointed to a bellcrank lever, H, fulcru med in the lug 7L3 (shown best in Fig. 13) on the handle-bar lug g g". To the other arm of the bell crank lever is hinged a vertical or nearly vertical connecting-rod, H H, which I make in two pieces coupled together by a small clamp, h", to permit of extending and contractingthis connecting-rod in length when the steeringpost is raised or lowered in adjusting for the height of the rider. The lower end of this connectingrod H is hinged to a lever spoon-brake, H H", (shown separately in Fig. 16,) which is fulcrumcd at h in a lug or lugs, If, on the under side of the lower fork of the frame. The lever part 11 of this brake is affected by a small spring, (shown in Fig. 1,) so as to keep the spoon part I away from or out of contact with the driving-wheel A; but the construe tion and arrangement of these parts are such, as will be obvious, that pressure upon the brake-handle H toward the handle-bar will cause the downward thrust of the brake-eonnectiug rod H and press the brake-spoon II against the tire of the driving-wheel. 1

K is a hinge and fulcrum bolt, which I secure in the lug o of the bracket 0 by means of its larger threaded part, It, and thejam-nut K. I prefer to make it with a conical bearing part, 7;, and a long threaded portion, 7;, upon which are threaded cones for bearings and securingnuts.

I prefer to construct the bracket C and its arms so that the under side of them shall be on a plane which, though perpendicular to the hinge and fulcrum bolt K, shall be inclined at a small angle to the horizontal plane when the machine is in its normal position on a level surface. Then the bolt K is inclined and the steeringspi ndles d (l areiuclined slightly backward, and the transverse reaches 1) D and connecting-rods G" t are practically level when they are extended, as shown in Fig. 2, but are inclined when they are partly folded, as shown in Figs. 3, 4, 5, 7, and S. The hinge-bolt L is also similarly inclined, so that the axes. of the bolts K and L and of the spindles d d and steering-heads B B are parallel and inclined in all positions. The object of making these 'parts inclined to the horizontal plane of the machine when in its normal position, instead of perpendicular to it, is to produce an inclination both parallel and equal to the guidingwheels B B when they are deflected. An inclination of these parts is made backward, so

that when the guiding-wheels are deflected the inclination of the guiding-wheels shall be to ward the center of the circle and are of which they are described in the act of steering, thus avoiding the liability to skidding 011 the ground and to stripping the tires and to strai uing the wheels and the machine. Upon the bolt K, at the conical seat k I place the lug d" of the end D of the right-hand bar D, which has a conical bearing to fit upon the conical seat, and next to it I place the lug d of the end D of the lefthand arm or reach D, which also has a reverse conical bearing, and then I set up into this last conical bearing the adjusting-cone It, which is threaded upon the smaller part, of the bolt K, so as to give a free but well adjusted hinge-bearing to the transverse reaches D D upon this bolt K. I then screw on the conical bearing-nut is, which serves both as a check-nut to the cone it" and as a part of the bearing for the fulcrum-lug of the bell-crank steeringlever G G, this latter having a double conical bearing and being held on its under side by the adj usting-cone lt'flwhich in turn is secured by the jam-nut It. On the hinge-bolt L, I thread first the cone E, which affords a bearing for the wrist g of one of the transverse steeringrods placed upon it. I then place the other wrist a", with a reversed conebearing, upon the bolt L, and follow it with the threaded cone Z, which adjusts the bearing of both wrists, and secure it and all the parts together by means of the jam-nut L. The construction and relation of these transverse reaches and their connecting parts, and transverse steering-rods and their connecting parts are such that as the reaches D D are swung to any position the guiding-wheels B B are preserved in vertical parallel fore-and-aft planes in whatever position of nearncss or remoteness to each other they are, these planes being also parallel to the vertical longitudinal plane through the middle of the machine.

I P are securing bolts or screws,scated in the lugs d d of the transverse reaches D D, and swinging with them freely when loosened in the slots 0 0 and which, when tightened, sc cure the transverse reaches in any desired po sition to the bracket 0. I prefer to make countcrsinks on the upper side of the lugs c" c, to receive the head or nut of the bolts 1 when they are brought tothe normal position, and thus increase the security of the parts; and similar eountersinks may be arranged at equal distances from thescone, two, or more in each of the arms 0 c, fora similar purpose, and also as guides for bringing the bolts to equal positions on either side in contracting the width of the machine. I also place a dust and mud guard, Q, over the driving-wheel, which maybe held to the forks 0 G by braces Q Q, as shown, or in any suitable manner.

It is obvious now that parts of my improvements may be used without using the whole of them, and that modifications in the form and ITO arrangement of details of the machine may be made by any one skilled in the art without departing from the substance of my invention; and I do not mean to limit myself to the pre cise things herein shown and described.
