TRICYCLE.

SPECIFICATION forming part of Letters Patent No. 328,761, dated October 20,1885.

Application filed September 10, 1885. Serial No. 176,684. (No model.)

To all whom t may concern,.-

Be it known that I, J. H. CILLEY, a citizen of the United States, residing at Lebanon, in the county of Lebanon and State of Pennsylvania, have invented certain new and useful Improvements in Tricycles; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an attachment for tricycles, whereby the ordinary tricycle of the front-steering77 class may be converted into a tandem velocipede to carry two riders.

The attachment consists of a frame, which, in the present instance, to illustrate my invention, is an exact counterpart of that which projects forward from the axle of the Columbia tricycle, and is provided with a wheel, pedal-crank axle, saddle, and handlebars. The frame is provided with side bars, having on their ends clips for attaching it to the axle of the tricycle and for forming a vertical joint to allow the frame to rise and fall to compensate for any irregularities in the road.

In the accompanying drawings,which form a part of this specification, Figure 1 represents a side View of a Columbia tricycle provided With my attachment; Fig. 2,a rear view of the same; Fig. 3,a side View of the attachment detached from the tricycle; Fig. 4, a side view of the spring-clip and a section of the ball-bearing case on the axle, Fig'. 5,a top View of the same; and Figs. 6 and 7 represent details of the construction of the steeringrod and its slide-bearing.

Reference being had to the drawings and the letters of reference marked thereon, A represents the frame of a tricycle to which the attachment is connected. The construction of this part of the machine being well known it will require only a general description of such parts as are necessary to understand my invention. a is the ax1e,upon which are mounted the driving-wheels b b; c, the small steeringwheel; d, the seat; e, the pedal-crank axle, f, the steering-handle, g, the driving-gear.

B represents the attachment for forming the tandem velocipede. c a are the side bars of the frame, upon the ends of which are formed spring-clips b b', which, in the present instance, are adapted to iit over and engage with the ball-bearing case c of the main axle a. d is the swinging-latch of the clip, connected to the frames afa at e', and adapted when thrown into contact with the spring-clip to engage therewith by the former passing through the slot f, formed in the latch, as shown in Figs. 3, 4, and 5.

The frame or attachment is provided with a wheel, C, a pedal-crank axle, D, a saddle, E, and handles F F, which correspond with those on the main machine. The seat or saddle E is adjustably supported upon an arched portion, G, rising vertically from the side bars, a a', of the frame. The arch or seat-support is braced to the rear portion-of the frame, as shown at i z'.

A foot-rest, H, is secured between the forward ends of the side bars for the accommodation of the rear rider when not operating the pedal-crank axle of the attachment. The frame of the attachment is of the same length and width as the main frame, and the front and rea-r wheels are therefore equidistant from the main axle. By this construction the machine is perfectly balanced and causes it to run evenly and smoothly without the jar which is incident to 'the single machine. The front and rear frames being of the same width the machine becomes a three-track machine,77 as the rear wheel follows in the same track as the front wheel.

Upon the main axle is permanently attached an additional driving or sprocket wheel, I, over which is passed a chain having a removable bolt (not shown) connecting the links at one point to provide for its being separated to attach it to the wheel I on the main axle and the wheel J on the pedal-crank axle D of the auxiliary frame.

The machine is steered wholly by the front rider 5 and to this end the front and rear wheels are connected by a rod, K K, which is attached to a lug, k, on the rod Z, leading from the arm m of the front wheel to the steeringhandle f. Io the inside of the main frame and the safety-stay is secured a guideway, n, in which is placed a slide, o, from which projects a stud or pin, p, upon which the inner ends of the rods are secured by a suitable washer,

thus forming a joint in the rod K K, which accommodates itself to any irregularities in the road, such as deep gutters or gullies, in crossing which the front and rear parts of the machine are thrown ont of the same horizontal plane. By connecting the front and rear wheels they are always under. the control .of the front rider, and are made to trail very accurately by reason of the rear wheel, C, having its steering arm or lever` q project from the opposite side of the wheel as compared with the wheel c and its arm m, and, that they are equidistant from the main axle, thus enabling the machine to be turnedA in a very small space.

Upon reference to Figs. 4 and 5, it willbev observed that the sidebars, ya. a', of theframe. areiiattened at vtheir ends and1 slightly bent, to facilitate the connection with the ball-bear;-

ing case, and that .by connectingv the fralnexto the saidl case no additional friction is incurred.

Another advantage of my construction is` that .v the tension of the rear driving-chain-` is. not affected by any of the irregularities inthe road, as the vertical joint formed by attaching therear frame to the ball-bearing case onv the mainaaxle allows .the entire frame to swingV freely without 4 in any manner changing. the tension of the drive-chain connecting themearv pedal-crank axle with the mainv axle.

The front and rear frames being connected. togetherby their attachment to the main axle in the same vertical plane form a-yery. stiff and substantial machine, and in climbing hills are` found to balance `cach other perfectly, thus enabling both riders to 'workv ontheir re-k spective pedal-crank axles without dangerfof tilting 4either end. f:

The4 crankaxles are set at different angles,

as ,shown ,in Figs. 1 and 2, thus always prof. l

viding against the machine being upon a dead- ,cente`r, i or one `rider working against the other,l

and presenting a ready means for starting the machine from any'position in Awhich it mayuhave been stopped.

I would `have it understoodIthat my inventionis not limited in its applicationto. the style of tricycle to which itis shown attached;`- but that it is` susceptible of changes to adapt it to different styles, which are mere mechanical expedients, and are held to be within the,v l

spirit and scope of my invention.

I am aware that tricycles haveheretofore.,

been provided with parts for converting them into tandem velocipedes, and do not, therefore, claim such anl attachment, broadly; but,

Having fully described my invention, what I claim is- 1. An attachment for tricycles,consisting of a frame.providedwithicontinuous side bars having their ends formed 4into clips for at-` taching them to the main axle, substantially as setforth.

2. An attachment for tricycles, consisting of an auxiliary frame, provided with side bars having clips formed on their ends, in combination with the ballbearing cases on the main axle, substantially as described.

8. An attachment: for tricycles,consisting of an ,auxiliary frame, provided with ,side bars having their end s `reduced ,and formed linto sp ringV-clips, substantially-as described.

4. A11V attachment for tricycles,consisting of an auxiliary frame having side barslandfan arched seat-support connecting said bars, substantially as described.

5. An attachment for tricycles, consisting of A an auxiliary frame having side bars, an'arched seat-.support connecting saidbars, and a footrest, substantially'. as described.

6. A velocipedehaving a iixed anda swinging frame,l ltwo driving-wheels, a frontand rear steeringwheel, and, a `suitable.steering deviceL connecting, said .steering-wheels, substantially as described.. t

7. -A velocipede having a front frame fixed,l

8. A velocipede .hayingl .a swinging frame attached to the main axle, two driving-wheels, front and rear steering wheels, in combination withl a hrod connecting saidv ywheels,provided with Ea jointto admit of vertical,movement,ofL the rod and swingingl frame, substantiallyL as andV for the purposeset forth.A
