DAVID HALL RICE AND LEPINE RICE, OF BROOKLIN E, MASSACHUSETTS.
VELOCIPEDE.
SPECIFICATION forming part of Letters Patent No. 358,057, dated August 24, 1886. 7
Application filed June 9, 1886. Serial No. 204,587. (No model.)
To all whom it-may concern:
Be it known that we, DAVID HALL Bron and LEPINE H. RICE, of Brookline, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Velocipedes, of which the following is a specification.
Our invention relates to velocipedes; and it consists in certain new and improved constructions and arrangements of the several parts thereof, substantially as hereinafter described and claimed.
In the drawings, Figure 1 is a side elevation of a velocipede provided with our improvements, and having aportion of the framework broken away to show the construction of particular parts. Fig. 2 is an enlarged rear view of aportion of the frame in section, with- Fig. 3 is a view of the steering-gear therein. a portion of the same parts as Fig. 2, with the frame sectioned at right angles to that of Fig. 2. Fig. 4 is a portion of the steeringgear detached and in section. Fig. 5 is an enlarged vertical transverse section through a portion of the frame and driving-wheel in line with its axis, showing the construction of the connection between the driving-drums on opposite sides of the wheel. Fig. 6 is a top plan view of one ofthe driving-drums shown in Fig. 5, with the frame-work connected therein part- 7 ly in section, to show the construction of certain parts.
IV is the large or driving wheel of the velocipede, which is of the variety known as a bicycle, and carries its small or steering wheel 10 ahead of the larger one. The saddle S is mounted over the main wheel, and is supported by the frame-work s s on each side of the machine,in the ordinary manner. ,The
steering -wheel to is pivoted in the tubular socket 10, within which is fixed upon it a pulley or wheel. This socket is carried on the lower end of the curved brace s, and out of it lead, on each side of the main wheel WV, tubular braces b b, leading backward to the tubular braces 12" b", which extend upward to the steering-handle, in the manner shown in the application of David Hall Rice for Letters Patent No. 183,638, filed November 28, 1885. "Within the tubular braces I) b asteering-cord is led downward from the steering-handle on one and from the center of this rises the sleeve 12,
which carries the shaft b of the steering-handle B. Shaft 1) extends downward into hollow socket b, and has upon its lower end a disk, I)", cam-shaped on-its lower face, as shown,
and shouldered on its upper face against a bushing in sleeve 1). Immediately below disk I) a lever, b, is pivoted centrally on the horizontal pivot b and extends transversely across in socket b so that its ends come over tubes 1) b On top of lever b is a disk, 11 having its upper face beveled to fit against the lower face of disk b for one half its surface, and the. other half cut away parallel with pivot bf, as shown, the beveled part of its surface being on the rear side of lever D The ends of the cord 0, which leads to the spindle of the steering-wheel, as before described, are made fast to the ends of lever b It is evident that when the steering-handle B is turned one way or, the other the cam-disk I), revolving with it, will press down upon the corresponding face of disk I), and depress one end of lever b and raise the opposite end, thereby moving cord 0 one way or the other and turning the steeringwheel. To aid the disks 1) b in working smoothly upon each other, a ball is placed between them in cavities in them fitting its upper and lower hemispheres, and in line with the axis of disk I), as shown in Fig. 4. The driving-wheel W has its hub w made tubular and provided with corresponding tubular extensions, 10 10 on each end, Fig. 5. 'The frame on each side of the wheel is comp'osed,as shown in the said former application, of two branches, m m. .The branchmis connected to thebr'aces s s of the frame, and extends horizontally outward over and beyond the driving-drum D; and thence vertically downward to receive the fixed bolt 0, extending through the center of the wheel through a hole in its lower end. The branch mis bolted onto branch m at its upper end by two bolts, m m, that end being forked or bifurcated for that purpose, and thence it extends vertically downward around the extensions 10 of the-wheel-hub and below the driving-drum D, whence it extends horizontally outward beneath the drum,and thence vertically upward outside of branch m, around the lower end of which it is shouldered, receiving through it the fixed bolt 0, which thus serves to join the ends of the branches at m together, whileit is in turn supported by them.
By this arrangement the wheel W is supported outside of its hub-extensions in bearings in branches m of the frame on each side, and the central bolt, 0', is independently supported at each end outside the wheel-extensions in a fixed position,beingsecured in place by nuts 0 a at each end outside the frame screwed onto it. The vertical braces m are grooved out around the extensionsw ofthehub of the wheel W on their inner faces, to receive balls or rollers r r, and corresponding grooves are formed outside of the wheel-hub at each end around the extensions 11; 10 to receive the balls, thus forming ball or roller bearings, on which the wheel runs. By turning the nuts 0 on bolt 0 these hearings may be adjusted as desired. The extensions w w have around their outsides ratchet-teeth r, and the drums D D revolve around them,and are provided with pawls r, in' the usual manner, to engage with the ratchet-teeth and drive the wheel W. These drums are connected by straps d d with the levers Z l, which are also of the ordinary construction and adapted to be moved downward by the feet of the rider to revolve the drums. In order to revolve the drums backward and wind up the straps upon them and 'raise the levers after each downward stroke, the springs ordinarily used for the purpose are dispensed with, and the following-described mechanism substituted therefor: The drum D overlaps and rests upon the extension w of the wheel-hub on its side of the wheel W, and has its outer end revolving about the fixed bolt 0' in a space left for the purpose within the inclosing branches m m of the frames. Connected to this drum D is a tubular shaft, (2 of slightly smaller outside diameter than the bore of the wheel-hub, which shaft extends through and beyond the latter and fits and revolves around the fixed bolt 0. ()n the opposite end of shaft d from drum D is attached the grooved pulley-wheel D, so as to revolve with it. The tubular shaft d and wheel D are supported at their outer ends by balls 7' r in grooves, which bear upon bolt 0 and relieve the friction. The drum D revolves around the extension '11; of the wheel-hub on its side on which it bears, and has formed on its inside end and the other side of its actuatingstrap d from pulley D a grooved pulley attachment, D, corresponding with D. Be-
tween the backwardl'y-extending arms 8 s of the frame of the machine on that side a pivot,
p, is attached to these arms, connecting them transversely, being attached to the upper arm, 8, by an elbowpiece, p, secured to it by screws p 19, so as to bring it horizontal. On this pivot p is hinged a metal strap, d, so as to swing freely in a vertical direction, (see Figs. 1 and 6,) and this strap carries on its free end the pulley d, pivoted to it at d, its pivot being at right angles, or nearly so, with the axis of shaft d. The pulley d is grooved to correspond with pulleys D" and D, and is of such a diameter at the bottom of its groove that the cord 0 will lead from it freely on one side to D and on the other to D. This cord is so wound onto these pulleys, after passing around d, that it goes around them in the opposite direction from that in which the straps d d are wound upon the drums D D, and so that when the strap d is unwound from drum D by the depression of lever l cord 0' will be wound upon the pulley D, attached to that drum, and at the same time the strap d will be wound upon drum D, and the cord 0 will be unwound from the pulley part D, attached tothatdrum. Thepartsbeinginthisposition, it is evident that the depression of leverl will unwind strap d from drum D and wind up cord 0 on pulley D; but this unwinds cord 0" from pulley D", which motion winds up strap (1 on drum D, ready for another stroke of the foot. The depression of lever l in like manner reverses the movement of the parts and raises lever l. The pulley d, swinging upon its pivot 10, automatically aligns itself with pulleys D" D, and works with very little frictiou, as the cord 0 can be made of leather, and, being short, is not liable to stretch and become loose. From the compact arrangement of the parts they can also be cased in protecting them from dust and dirt. The same adjustment of the ball-bearings of the main wheel W by the nuts 0 also serves to adjust the balls 7'' in the bearings of sleeve d, and washers of different thicknesses can be used around bolt 0' against the balls for that pu rpose. From the arrangement ofthe parts the weight and friction of the main wheel W are taken entirely offofshaft d, which is important to its freedom of action, and but little force is required to raise the levers ready for the return-stroke.
In putting the machine together the arrangement of the frame serves a useful purpose. The parts m m are first slipped over the extensions w w of the wheel-hub, with the balls 7' in place, and the inner part of the drum D put on. The ratchetteeth are then keyed onto extensions w w. The outer face of drum D is bolted on, and the drum D and its tubular shaft d are slipped into place from the opposite side of the wheel, and the pulley D" driven or keyed onto the free end of the shaft. The branches m m are then bolted in place in the frame, and the balls 1' 1' are inserted and the bolt 0 passed through the center of the whole, and the nuts 0 set up to adjust the bearings. To facilitate this operation the drum D is made to open on itsinner face,
instead of on its outer face, like drum D; but its outer face-plate may be attached to shaft d", in which case it will open on the outer face, like drum D.
Instead of making the tubular shaft (l to revolve about the fixed bolt 0, with drum D and pulley D upon its ends, it may be made in one piece with the bolt 0 and allowed to revolve in the frame and accomplish substantially the same connection between the drums D and D without departing from the spirit of our invention; but we prefer the construction first described, as giving greater stability to the frame. It is also evident that the parts of the frame branches in and m, which inclose the drums D D on the outside, and the bolt 0 might be entirely dispensed with, and the tubular shaft (1 made to take a running bearinginside of the tubular hub of wheel W, and our connection between the drums D D be preserved and operate substantially as before. It is further evident that our connection between drums D D may be preserved if the balls r r be removed from about the hub of wheel \V, and the latter allowed to take its bearing upon the outside of the tubular shaft d", instead of in branches at of the frame.
