Ap lioat'i n front and rear of said seats; also opposite each 1 5 seat-are :a' pair of handles connected to mech anism' for guiding the-front .wheel, each pair of handles being capable of guiding the bi-' cycle independently.

:The objects of my improve nents'are, first,-

. .26. to provide 'a bicycle which iscapable of seating, side by side, two'persons; second, to afford facilities for the "proper adjustment of the seats to suit a heavy and light person and the. guiding of the machine, and, third, to -.provide means of applying one of the adj justableside seats to a:midd1e.position.lo cated ona line with two ground-wheels'when the sideseats are not used. I attain these objects by the mechanism illustrated .in the 39 accompanying drawings, in which Figure 1 is a side elevation. 'Fig. 2 he .plan of abicycle, these two viewsembodying .my invention. Fig; 3 is'a front elevation of the same, the seats, rear wheel, and driving.

The. two sides of the frame of the bicycle, tubular in section, are indicated 'byA, and. are held in relative position by means of the l front cross-braces Band C, with centralfr'ont t Ne; 1 1,561, dated August 4, 1896. a: reissue filed'Ieln-nary 25,1896. Serial No. Bea-764..

partuk ofi-frame, the seat-braces E and F, and the rear rigid axle H, provided with nuts I to secure said axle to-frame. The two ver- .tical tube-standards A, towhich the'upp'er i end of said braces F are connected, also form a part of .theframelfl. The seat-supports J have slotted holes 2 for'the purpose of attachin g and adjusting thereto aseat or saddle and are provided with under shanks. J, which fit into the said tube-standards and are capable of vertical and horizontal adjustment and held in desired position by means of set-screws 1 This horizontal adjustment'of said seatsupports tends to evenly balance the machine sidewise when one person is of greater weight or longer proportion than his or her partner.- '-A- cross-brace K, having two rearward curves to alloy perfect freedom to the inner limbsof the side cyclists, is a part of or at- .tached to the middle or lower part of the standards', and has a hub similar to the upper endsof said standards to allow one of the said seat-supp0rts Jtobe inserted therein, forjthe purpose of seating one person inthe middleof themachine. v x i It will be perceivedtha't the bra'ceE, the forward end of which is attached to 'the'middle of the front part of frame by means of lugs 4 and pin and the rear endfto the to'pof central hub. of said seat-brace K by detach- 8o able pin 5, can, by removing this pin and at the same time one of the supports J, -be attachedto the upper end of either one of the two standards and held in position by inserting s'aidpin 5 or a support J, or in' lieu of "said pin three seat-supports may be supplied. The three preparations alluded to forjseatsupports are'on the "same circular line-from 'radial center of lugs 4, in which said brace'E is allowed to 'swiveL.

It'will be noticeable that the foot pedals or" cranks Mare placed in position to allow the inner limbs of the cyclists to'operate together,

though one .of' the two may be changed to an angle when the machine is operated from the central seat. These cranks drive. the rear ground-wheel N in'the ordinary manner ofbicycles .by means of the belt or chainwheels 0, the belts P, and the belt-wheels B. These belt-wheels R form a part of the extensionhubs S, which revolve on the said throughaxle II. Each said extension-hub has an opening 6 to allow for the adjustment of ballbearings, if usedand if necessary. The central hub N of rear wheel N has a slight round projection 7 at each end which fits into the mediately above the fork proper, as seen in Fig. 3 of the drawings. This line 9 denotes the lower end of the central front part A of the frame A and the commencement of said shank. The upper end of this shank is se cured to the inner end of the central lever V handles W, operate the central lever V by means of cross-rod Y, which is oonneotedto the outer ends of the three said levers. Either part of front-of frame.

of the two levers V, and the inner end of each of the side levers V is secured to each of the shanks. .W of the guiding-handles W, said sha'nk's fitting into the side tubes of upper These two side levers, when operated by one or both the said pair of pair of handles will suflice to guide the machine, as both pairs are connected to the said cross-rod.

The handles could be so arranged as to be interchangeable-that is, to allow either pair to be applied to the hollow or tube shank of the fork. This would be in case one person was on the devised central seat on the brace K.

This interchanging could be accomplished by simply inserting the shank W of either of the two handles into the tube or round aperture of shank of fork and fastened to same by means of set-screw or other convenient In case a lady should occupy the central seat the brace E may be removed.

It will be obvious that by the factof the interchanging of the seats, as previously mentioned, and also by the fact of the guiding mechanism being applicable to'either one of the three seats a cyclist may take a partner to a distant city and return alone on the bicyole, this being a very important element in my invention.

What I claim as my invention is- 1. In a bicycle, the combination of sideframes held suitably apart by means of crossbraces and the axle for the rear wheel, the wheels being journal'edi thereon centrally between ;said side frames; a hub for the rear wheel sleeved onthe axle and extending outwardly from the wheel between said side frames; separate driving mechanism connected with the outer endsof said extended hub and driven independently from each of said'side frames, and steering-gear for the front wheel, substantially as described and specified.

' 2. In a bicycle the combination of side frames of any construction held suitably apart by means of cross-braces and the axle for the rear wheel; a rear wheel located between said frames; a hub on said rear Wheel sleeved on said axle and extending outwardly from said wheel into proximity with the said side frames; seats located on standards from each of said side frames; crank-arms provided with pedals and connected with axles suitably journaled on the crank-hangers of each of said side frames; pedal sprocket-wheels on the axles of the crank-arms adapted to drive rear sprocket-wheels fixed to each of the outer ends of the extended hub of the rear wheel and immediately behind the pedal sprocket-wheels; and a front wheel suitably journaled midway on the front cross-braces between the side frames and steering-gear for the said front wheel, substantially as described and specified.

3. In a bicycle, the combination of side frames of any construction held suitably apart by means of cross-braces and the axle for the rear wheel; a rear wheel located between said 'frames; a hub on said-rearwlieel sleeved on said 'axle and extending outwardly from said wheel'int'o proxlmitywitlithe side frames seats located on standards from each of said side frames crank-arms,provided with pedals and connected with axles suitably journaled onthe crank-hangers of each of said side frames; pedal sprocket-wheels on the axles of the crank-arms adapted to drive rear sprocketwheels fixed to each of the outer ends of the extended hub of the rear wheel and immediately behind the pedal sprocket-wheels, and a front wheel journaled on its fork, the forkstem being held bya head located on the front braces midwaybetween' the side frames; a lever fixed to the fork-stem and pivotally connected with a cross-rod; levers fixed to the shanks of the handles journaled on the side frames and also pivotally connected with the cross-rod, substantially as described and 4. The combination of the two-sided tubular frame A, with the central front tubular part A, to receive shank of fork U,and connected together by means of the cross-braces B and G, each side of said frame havinga vertical tubular standard a; which are capable of supporting the seat-supports J, provided with slots 2, by means of their shanks J, and held in position by means of set-screws 3, the curved cross-brace K connected to. said standards, and having a central hub of same height adapted'to receive the shank J, of seat-supportJ, the brace E, its forward end pivoted to lugs 4, its radial center'and its rear end capable of attachment to either of the upper ends of said standards or the said hub of crossbrace K, by means of the'insertion of one said shank J or of pin 5, the brace F, the crankpedals M, and the ground-wheels, substantially as described.

5. The comb'nation of the two-sided frame A, with the central front part A, of tubular construction to admit the shank of fork U, in
