TRICYC LE.

SPECIFICATION forming part of Letters Patent No. 326,2H, dated September 1, 1885.

Application filed May 27, 1885. (N0 model.)

To all whom, it may concern.-

Be it known that 1, DAVID HALL RICE, of Lowell, in the countyof Middlesex and State of Massachusetts, have made a new and useful Improvement in Tricycles and other Similar WVheeled Vehicles, of which the following is a specification.

My invention relates to tricycles and other similar wheeled vehicles; and it consists in certain novel and useful combinations of the various parts of the same, with the object of enabling the breadth of the track made by the wheels of the same to be varied or set to different gages, substantially as hereinafter described and claimed.

Heretofore it has been found expedient to make such vehicles as narrow as convenient for the rider to sit on and work the operative parts-such as treadles, steering-gear, brake, &c.in order that they may be stored in as compact a space as possible and take up as little breadth as possible in traversing paved or smooth streets; and it has been found possible to reduce the gage of the wheel-treads to about thirty inches, and the outside horizontal distance across the two opposite wheels to thirty-six or thirty-seven inches. It is, however, a well-known fact that it is difficult to propel such machines over many country roads, because only two of the wheels can be brought to run in the smooth tracks made by ordinary wheeled vehiclesviz., the steeringwheel and one driving-wheel-the other driving-wheel traveling over the rough portions of the road between the wheel-tracks, because the same are a much greater distance apart than the tricycle -wheels of the gage mentioned, often being fifty six inches apart. Again, even when the tricycle is made as narrow as above mentioned it will not pass through many ordinary gates or doors.

It is to overcome these disadvantages that my improvements are devised, and they may either be employed to make the vehicle narrower than the width mentioned, or to increase its breadth to that of the wheel-tracks of ordinary road-vehicles.

In the drawings, Figure l is a top plan view of a portion of a tricycle, partly in section, provided with my improvements. Fig.2 is

a section of the same on the dotted line as a: of Fig. 1.

A A are the two large wheels of the tricycle, which are driven by the central drivingclutch and propel the vehicle.

A is the steeringwheel, mounted upon an arm projecting forward and downward from the tubular frame F, which arm is letteredF. The tubular frame F is in two parts, connected by arched straps or barsf f, to allow space for the clutch G, which drives the divided wheelshaft 8 s. This clutch G is the same patented to me in Letters Patent No. 316,061, dated April 21, 1885, and this patent is referred to for the details of its construction. The shaft 8 s is supported in the outer ends of the tubular frame F by the well-known ball-bearings To the disks, dd, which revolve with the shafts. The faces of these disks are turned perfectly true in planes at right angles to the axis of shaft 8 s, and they extend outward beyond the tubular ends of frame F to some distance.' Through each disk d are bored four equidistant holes, parallel with the axis of shaft 8 and outside the periphery of frame F, and these holes are lettered h h in Fig. 8. Through these holes slide four rods, 0* r. The inner spoke-flange of each wheel d d has four similar holes made through it in line with those in the disks d d, and the rods 1' 0" pass through the wheel disks by means of these holes in them. The outer and inner faces of these wheel disks are trued up in planes perpendicular to the axes of these holes. The hub of the wheel between the outer and inner spoke-disks ismade no larger in diameter than the tubular frame F. The four rods 1' r on the end of shaft 3 on either side of the machine are formed into the telescoping part of the shaft as follows: Before they are passed through the disks d d, as described, a disk, d is brazed upon the center of these rods by passing them through holes in it which register and are in line with After passing the inner ends of rods r 1' through the holes in disk d a ring disk, (i is slipped over the tubularfr'ame F,having a hole in its center to receive'th'e latter, and four holes in it corresponding and in line with the four in disks (Z d. Into these four holes in disk (I the inner ends of rods 1' are passed and firmly secured, so that the face of the disk toward disk at shall be perpendicular to the axes of the rods. The hole in the center of disk (1 is considerably larger than the tubular frame F, which it surrounds. The outer ends of the rods 1' a are passed through the wheel,spoke-flange, or disk d before it is attached to the wheel, and a ring-disk d is attached to the outer ends of these rods by four holes, as before described, so thatits faces shall be perpendicular to the axes of the rods. The hole in the center of disk d is larger than the central part of the whee1-hub,and is next slipped over the latter, and the disk cl is secured to the hub so that its faces shall be in planes parallel to the tread of the wheel. The rods 7' r are now in the po' sition shown in Fig. 1, in which they are firmly held together by the disks (1 and (1 at their ends and thedisk d at their middle part, and slide freely through disk d, which connects them to the shaft s,and through disk d,which connects them to the wheel A. These four rods thus form in their outer parts an extension of the shaft s,telescoping into the space between the spoke-flanges of the wheel-hub, and in their inner division from disk d an extension of the shaft telescoping around the frame F and shaft-bearing f hen the faces of disks (1 d d are brought together, as shown at the right-hand side of Fig. 1, the wheel is closed and held in a plane at right angles to the axis of shaft 8. When the faces of disks d d and d d are brought together, the wheel is opened, and is held in like position with relation to the shaft. This effect is greatly assisted by making the faces of the disks true up to the shaft when brought together, as described, but it may be accomplished by properly fitting the rods 1- r in the holes in disks d d in which they slide, and the collars (Z (1 around the frame and the central part of the wheel-hub over which they slide, respectively. It will also be observed that one part of the telescoping shaft may be used without the otl1er-as, for instance, the part outside of disk (I may be slid out or in without moving the part inside of that disk, .or vice versa.

In order to secure the compound telescopingshaft in position when drawn out or in, I have adopted the following mechanism: In the collar d (Figs. 3 and 4) are made radial holes, passing inward, so that a portion of each shall be cut by the circumference of a hole, .h, as shown. These radial holes are tapped out with a screw-thread, and a screw made with a slightly tapering body is fitted to each, -as at s" s". In 6.1.011 of the rods 9' r, (Fig. 4,) at the place or places where it is desired to secure them to the disk d, is made an indentation or depression, a n, into which the screw 8 will fit, wedging as it is turned home. These de pressions are also so made that the screws 8 s" will draw disk (1 or (1 against the disk d firmly when adjusted against the latter. Besides being a very powerful fastening, the

screws 5* s possess the advantage that they cannot be driven home until the notches of the rods 1' are brought to register with them, and the operator will not be liable to wrongly adjust the respective parts. The disks d d are provided with similar screws, and the parts of rods 1" r sliding through them with smaller notches to secure them to each other.

The outer spoke-disks, d may be employed to assist in truing up the wheel when closed, if desired, by bringing their inside fiat faces against the outer faces of disks d d.

I do not intend to confine my invention to the precise form of telescoping the shaft within the hub of the wheel shown in the drawings, as it is evident that it may be modified somewhat, and the space within the hub of the expansion spoke-wheel still utilized for that purpose. The part of the telescopingshaft sliding over the frame F may also be modified in form without departing from the spirit of myinvention-as, for instance, it may be tubular and confined to disk d by a spline and, groove; but I prefer the construction shown.

When the tricycle is to be narrowed, so as to enter doors of. less than thirty-six inches in width, it becomes necessary to move the steering-handle and its connected mechanism on one side of the machine and the handle and brake on the other inward toward the center of the machine,to allow the wheels A A to be telescoped inward sufliciently, which is accornplished as follows: On the rear side of the tubular frame F are attached two sleeves, 0 0, provided with set screws 0' 0 through them. In these sleeves are fitted short vertical rods 0 0 so as to turn therein, supported by collars attached thereto, 0 0 resting on top of the sleeves. From the lower ends of these rods curved arms 0 0 project sidewise and forward, asshown, so as to be out of the way of the limbs of the rider, and at their outer ends sustain vertical tubes 0 0. The lefthand tube 0 serves as a bearing for the shaft of the steering-handle, (Figs. 1 and 2,) and the right-hand one as a socket for the handle on that side, these shafts being shown at 0 and 0 The shaft 0 carries at its lower enda pinion 0. Above and below this pinion on the shaft 0 are pivoted the ends of a strap, m, so as to swing freely around the pivoting. This strap extends radially from the shaft and incloses thesteering-bar m, holding it in place at that end, so that its rack will mesh with the teeth of pinion 0 and the strap is elongated horizontally behind the bar to guide it in its reciprocating motion, as shown. The other end of the steering-bar is attached to'an arm, m, which in turn is journaled upon the pivot on in the rod m, to which pivot the axle of the steering-wheel A is attached. The hub of the steering-wheel revolves around this axle, and the steering is done in the usual manner. When it is desired to remove the steeringshaft 0 toward or away from the center of the vehicle, to telescope the wheel out or in on that I CC) IIO side, the set-screw 0 is loosened, and the arm 0 is swung around to the desired position. As the strap m is pivoted at the end of this arm, it will allow this to be done without disturbing the relation of the rack-teeth of the steering-bar to the teeth of the pinion 0 or, in other words, these parts automatically adjust themselves to each other. It is evident that a slide might be used to move the pinion out and in with the same effect, provided the strap on be pivoted to the pini0n-shaft. The handle-shaft 0 011 the other side of the machine is provided with a similarstrap, o, pivoted upon it and surrounding the brake-handle u, so as to allow the latter to play up and. down therein, and the brake-handle is pivoted so as to move in and out horizontally by the pivot v", (shown in dotted lines,) while it is made to turn the brake-rod o vertically. The

brake-rod is therefore free to swing in and out with the attached arm 0 as the latter is'adjusted in posit-ion, in the same manner as the steerer-arm on the opposite side of the machine.

As the steering-wheel will require adjusting to and from the center line of the machine to have its track with the wheel A on that side, I provide the following adjustment for that purpose: The arm F carries the sleeve 6 at its outer end. Through this sleeve the rod m, which carries the steering-wheel, slides trans versely of the machine. A set-screw, e, and one or more notches, e serve to secure the rod m in the desired positions to have the steering-wheel track with the one behind it, this set-screw working in the notches as the screws 8 work with the notches in the sliding rods 7*, 1

manner, or even a greater number than four,

without departing from the spiritof my inven tion.

The machine is driven by the usual metal chain-strap connecting the gear-teeth on the outside of clutch O with the sprocket-wheel c and cranks c c, and it is to be provided with the usual central seat for the rider, attached to the frame over the clutch, which is not shown in Fig. 1, as it would obstruct the view of the shaft and other parts here in question.
