8 Claims.

This invention relates to vehicles of the tricycle or velocipede type.

Among the objects of the invention are to provide:

An improved vehicle of the class referred to;

A vehicle of the class referred to having an improved frame or body construction;

An improved frame or body construction for vehicles of the class referred to.

Other objects will be apparent to those skilled in the art to which our invention appertains.

Our invention is fully disclosed in the following description taken in connection with the accompanying drawings in which,

Fig. 9 is a top plan view to an enlarged scale, substantially full size of some of the parts of Fig. 8, the view being partly in section and partly broken away and being considered as taken in the direction of the arrow 9 of Fig. 8:

Fig. 10 is a view taken from the plane Ill-I0 of Fig. 9.

Referring to the drawings, we have shown at l the vehicle front wheel, rotatable on bearings on a fork 2 the fork having a castering bearing at 3, to be more fully described, and handlebars 4 connected thereto, within reach of a rider on the seat 5 supported on a frame shown generally at 6, the frame at the rearward portion of the. vehicle being supported on rear wheels The parts referred to constitute no essential part of our invention and may be variously constructed; except as to the frame 6 and its castering bearing 3 and the connection between the frame and the axles of the wheels 1 wherein our invention resides and which will now be described more fully.

The castering bearing referred to generally by the reference character 3 comprises in the preferred embodiment a metal tube 8, preferably relatively thick walled, having pressed. into opposite ends thereof, bearing bushings 99 provided with finish flanges l0l0 overlapping the ends of tube 8; and it is within the bores of the bushings 9-9 that the stem of the fork 2 above referred to has castering bearing.

The frame proper, referred to generally at B in Figsrl. and 2, comprises a pair of metal tubes l l abutted upon and welded to the tube 8 at their forward ends, (see also Figs. 5 and 6) the tube 8 being shown in Fig. 6 without the bushings 9--9 for clearness. The tubes II-ll extend rearwardly from the tube 8 and diverge from each other as plainly shown in Figs. 2 and 6. A metal bracing member in the form of a gusset [2 preferably triangular in form is welded along one edge as at I3 to the tube outer wall 8, extends upwardly between the adjacent tubes HH and is welded likewise thereto. By this construction the front end portions of the tubes ll-Jl, the bearing tube 8, and the brace l2, are all integrally welded together.

A saddle post socket i4 is formed from a piece of thick Walled metal tubing and opposite sides thereof are grooved as at |5|5, generally to the radius of the tubing H-H and the tubes H-Jl are laid in the grooves l5--l5 and Welded to the tubing piece l4; and a set screw l6 may be provided through a Wall of the socket 14 to clamp the saddle post H, see Fig. 1, therein in suitably vertically adjusted position.

A channel element l8 of sheet metal, downwardly open is placed over the structure thus far. described. The web IQ of the channel rests upon the upper side of the tubes lll I, the flanges 20-20 of the channel lie along the sides of the tubes ll--II and the forward end edges 2I-2l of the channel flanges lie upon the side of the tube 8 and are welded thereto. The channel flanges are also welded for example, as at 22-22, to the tubes ll-H; and the channel flanges 202ll are preferably of greater vertical depth adjacent to the tube 8 than at their rearward end portions.

When the vehicle is in use, and the front wheel I rests on the ground and load is applied on the seat 5, forces are developed in the structure thus far described which tend to bend the tube 8 off from the ends of the tubes I I I l and which tend to twist with torsional force, the forward ends of the tubes il! 5, and these forces are resisted with the maximum of resistance for the miniofmaterial by the structure above described; and the channel i8 besides absorbing torsional and bending forces covers the parts in a manner to render the construction pleasing in appearance.

The tubes H-H diverge rearwardly from the head construction just described and extend rearwardly and downwardly therefrom and at their lower end portions 23-23 are bent so as to extend forwardly again, thus providing at about the level of the axis of the rear wheels L-ll, substantially straight horizontal forwardly extending portions 24-24 spaced apart transversely.

As shown in 3 and 4, the ends 2fl2 l of the tubes H--I l have inserted into their ends turned solid metal pieces 2525 supporting opposite ends of a wheel axle 26. The axle preferab-iy has at opposite ends thereof reduced diameter portions 2l21 which are fitted into suitable transverse bores in the pieces 25-25 and outwardly of the said pieces has reduced diameter portions 2828 upon which the wheels 7 or bearings thereof are mounted, the portions 28 having threaded ends 292 for retaining nuts.

Forwardly beyond the axle 26 the pieces 25 are joined by a transverse piece of metal tubing 3d and rearwardly thereof the tubes 1 l! I are joined by a transverse piece of tubing 3|, the tubing and 3i and the axle 21 all being preferably of substantially the same diameter and disposed in substantially a horizontal plane thus providing a platform upon which a rider may stand.

The

parts

26, 35, BI and ii-ll just described are joined together preferably by welding to provide smooth rounded joint corners and edges therebetween as illustrated in the lower half of Fig. 3. The

parts

39 and 31, as described, also perform the dual function of rendering the frame at the rearward wheel supporting end rigid to maintain the wheels L4 in forward and rearward alignment.

By the foregoing described construction a rigid but light frame or body is provided for vehicles of this class.

In Figs. 8, 9 and 10 is illustrated amodification. In this form the forward head construction 32 may be the same as that more completely described above; the rearwardly extending frame tubes llal la in this form however do not diverge as much as in the first described form and at their lower ends have forwardly extending portions 24a2='a which are secured to a generally oval frame 33.

The frame 33 is preferably made from a tube 35 bent into oval form. An axle bar 36 extends longitudinally of the frame 33, having reduced diameter wheel bearing supporting axle portions 31-31. The axle bar 36 is preferably secured to the frame 33 by laying the axle portions 31-37 in groove 38 in the ends of the oval frame 33 and rigidly joining the axle bar to the frame by welding as at 39 which welding also restores the strength to the tube which was reduced by the the tube from which the oval frame 33 is formed,

abut upon and are welded as at M to the outer lateral sides of the portions 2da, 2fia. A connecting piece of tubing 42 is inserted between the portions 24a24a of the frame tube {thus oomleting the oval configuration of the frame and strengthening the attachment of the frame and the frame tube to each other.

The oval 33 and its connected parts provide a rigid grating or platform which not only rigidly positions the rear wheels l-l on their axle portions 3'I31 but as in the first above described form provide a platform upon which a rider may stand while straddling the frame tubes l la-I la.

Our invention is not limited to exact details of construction shown and described. Two forms of frame are shown and other changes and modifications may be made within the scope and spirit of our invention and without sacrificing its advantages and within the scope of the appended claims.
