. SPEQIFICATION forming part of Letters Patent No. 254,082, dated February 21, 1882.
Application filed July 13, 188|. (No model.)
To all. whom it may concern Be 1t known that I, GEORGE IVIARD, of Batavia, in the countywof Geneseemidtate of New York, have invented new and usef'ul Improvements in Velocipedes, of which the following is a specification.
This invention relates more particularly to a velocipede or bicycle in which the cranks are provided with connecting rods or arms to which treadles are attached,in order to enable the velocipede to be used by riders of varyin g sizes.
The obj ect ot' this invention is to so construct thevelocipede that the treadles can be quickly adjusted to the size of the rider and be used with ease and convenience.
My invention consists, to that end, in providing the connecting-rods with adjustable treadles, which can be readily raised and lowered on the conneclimg-rodsl as hereinafter fully described.
In the accompanying drawings, Figure 1 is a side elevation of my improved veloeipede. Fig. 2 is a fragmentary top plan view thereof. Fig. 3 is a longitudinal section of one of the bearings which support the upper end of the connecting-arms. Fig. 4 is a plan view thereof. Fig. 5 is a similar view to Fig. 3, showing a modified form ofthe bearing.
Like letters of reference refer to like parts in the several figures.
l A represents the front or driving wheel, B the rear wheel, and C the reach, all of any or dinary and well-known construction.
D represents the bifurcated or U-shaped frame which straddles the driving-Wheel, and which is-provided at its lower ends with bearings or journals, in which the axle c of the driving-wheel rotates.
fare two crank-arms secured to the axle e on both sides of the wheel A, and'g are two connectingrods pivoted at their lower ends to the free ends of the cranks f by means of crank-pins h. The connecting-rods g extend upward from the cranks f on either side of the driving-wheel, and each is guided at its upper end in a bearing, 7c, formed at the end of an arm, 7c', which is secured to the bifurcated frame'D of the machine.
freely therein ill the different positions which :grooved rollers l, between which the upper parts ofthe connecting-rodsg slide as the cranks fare rotated, the frictional cont-act of the parts being diminished by the rollers l.
The bearings k may be provided with an opening, k2, made large enough to receive the end of the rod g, and rounded at its edges, as shown in Fig. 5, to allow the rod tov inove.
6o it assumes when the machine is in motion.
The upper portion of the rods g are preferably made round in cross-section to correspondwith the grooved rollers Z or the opening k2 of the bearing la', and the lower portion of the rods g is flattened and provided with a slot, nz, to receive the foot pedal or treadlc o. The latter is provided with a center pin, o', which is inserted through the slot m of thearm g, and is secured thereto by means of a screw-boltand nut, o2. Upon loosening the nuts ofthe bolts o2 the treadlcs o can be easily raised orlowered on the rods g, and when adjusted to the desired position they are tirmly held in place by tightening the nuts of the bolts o2.
By means ot` the connecting-rods g the trva dles can be adjusted to any desired height to the rods g, substantially as set lorth.
2. Thecombination, with the cra-nksf, ofthe connecting-rods g, provided with slots m, and adjustable treadles o, secured to the rods g by 9o set-screws o2, substantially as set forth.
