BICYCLE.

SPECIFICATION forming part of Letters Patent No. 496,616, dated May 2, 1893. Application filed October 19, 1892. Serial No. 449,367. (No model.)

To all whom it may concern:

Be it known that I, CALVIN S. PAGE, of Pontiac, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Bicycles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form part of this specification.

This invention is an improvement in bicycles, and its objects are, first, to provide an improved drive, by which the machine can be propelled through the medium of oscillating or vibrating pedals; second, to have one pedal raise during the depression of the opposite pedal without the employment of lifting springs; third, to improve the construction of the frame; fourth, to provide improved anti-friction bearings for the drive-wheel on its axle.

The invention therefore consists, first, in

the novel construction of the propelling gear,

specifically described, reference being had to the accompanying drawings by figures and by letters of reference marked thereon to designate parts referred to by such figures and letters in the description.

Figure 1 represents a side elevation of the complete bicycle, of the safety type, embodying my improvements. Fig. 2 is an enlarged View of the driving wheel, hub and axle, with the outer shell removed. Fig. 3 1s a longitudinal vertical sectional view on line 33 Fig. 2. Fig. 4 is a detail sectional view of the ratchet mechanism detached. Fig. 5 is a detail View of a part of such mechanism. Fig. 6 is a detail.

The frame.-The frame of the machine is roughly diamond shaped. Its rear members A, A, are bifurcated to straddle the rear or driving wheel Y, and are rigidly connected at their rear ends to the axle, and to each other. The front members A A are connected at their rear ends to the front ends of members A, A, respectively, and at their front ends to the rearwardly inclined sleeve A through which passes the steering rod A the lower end of which is bifurcated and is connected to the axle of the front wheel Z. A handle bar is secured to the top of this steering rod as shown. A is a combined mud-guard and brace,.connected at its ends to the points of junction of members A, A and. A, A respectively. The several members of the frame are preferably made tubular, and welded. together at their junctions. Ordinary mudguards are attached to the frame as indicated, and the wheels may be of any desired construction. The saddle bar a is connected to the upper end of member A, and its upper end a is'bent horizontally backward. The saddle is clipped onto this portion a, in any suitable manner.

The drt'oe'mechanism.The rear axle O, on

which wheel Y is mounted, is stationary, and

its ends are secured to the bifurcations of member A of the frame in any suitable manner. To the center of this axle is rigidly secured a transverse shaft D,.projecting equally on each side of the axle, and having a central cylindrical enlargement or boss d through which the axle passes. The ends of this boss are concaved at the meeting edges of their sides and face as shown at (1. Upon axle C at each side of boss dare placed sleeves E, E Whose bore is of greater diameter than the axle around which they revolve freely. The inner ends of said sleeves are about equal in diameter to boss d and are concaved as shown at eopposite grooves d and a series of antifriction balls 2, 2, are confined in and between the concaved ends 01', e, of the boss and sleeve as shown in Fig. 3. Ooncaved rings 6 are fitted in annular recesses e in the outer ends of the sleeves, and a series of anti-friction balls 3, 3, are confined between said rings and concaved faced nuts e screwed on the threaded ends of the axle as shown. By this means the sleeves E, E are supported on but out of contact with the axle by anti-frictional ball bearings. On the outer ends of sleeves E, E are formed or secured small band pulleys F, F hereinafter referred to. On-the inner ends of the sleeves E, E respectively are rigidly secured bevel gears G, G which intermesh with similar bevel gears g, g journaled on the opposite ends of shaft D so that when sleeve E turns in one direction sleeve E must revolve in the contrary direction, and vice versa. Gears 9, g are confined to the shaft G by means of nuts 9 provided with suitable washers and nut-looks g 01' other suitable meansemployed to retain the gears on said shaft. H, H designate the hub end plates each being annular and fitted loosely on said sleeves E, Erespectively, to the inside of pulleys F, F. The plates are supported on the sleeves by means of the annularly concaved bearing rings h, and f, the latter being fitted around the sleeves against the inner face of pulleys F, F, and the former being fitted into the central openings of plates H, G, a series of anti-frictional balls 4, 4, being confined between the rings as shown. Each ring h is provided with a flange h by which it is kept in position within the hub plates. Screws f are tapped through the webs of pulleys F, F and bearagainst the rings f and by means of these screws the latter rings can be adjusted in relation to rings h, so as to equalize the pressure on balls 4, 4. The plates H, H are connected at their peripheries to a cylindrical hub shell H in any suitable manner, said shell and plates forming a hollow hub and inclosing and protecting the working parts and ball bearings from dust and grit. It is also provided with circumferential flanges H to which the spokes may be connected in any manner desired. Four or more or less slots H are formed in plates H, H and in these slots are placed dogs or pawls I, 1 shown more clearly in Fig. 4. These dogs are about as wide as the plates are thick, but each has an outwardly projecting tooth i on its outer edge near one end,- and its other end is recessed as at 7; to fit a corresponding projection or tooth H at the rear end of the slot in which it is confined. The slots are made of such size that when the pawls are inserted therein the toothed ends of the pawls can be swung back and forth or rocked on teeth H while the other end is retained in the slot. The corner of pawl I opposite tooth 't' is recessed as at i to enable the pawls to be easily slipped in place. When the pawls are swung outward they respectively engage with ratchet faced rings J, J secured to or formed on the inner faces of pulleys F, F, as indicated in Fig. 3. The pawls are prevented from swinging so far inward as to drop from slots H by means of annular disks K, K located to the inside of and opposite plates H, H respectively. These disks are supported on gears G, G respectively by means of pins It, It, which rest loosely in holes G2 in the outer faces of said gears as shown in Fig. 3. The disks however are permitted a slight amount of lateral movement toward and from plates H, H and when moved toward said plates will rock the pawls and cause them to engage their ratchets. To the inner face of disk K and near its periphery are attached arms which extend parallel with the axle across nearly to disk K, said rods being of such length that when one disk is moved inward,-the other disk will be through the agency of said arms or rods, forced outward, so that if either disk be fully shifted so as to allow the pawls in the adjoining plate to disengage their ratchet, the pawls of the opposite plate will be forced into engagement with their ratchet. Preferably the free ends of rods 70 are provided with frictionv rubbers or rollers k Openings or recesses K are made in disk K at the same relative points as rods k on disk K, there being one opening for each disk. The ends of said openings are beveled as shown in Fig. 7 so that the rods will ordinarily move therepast without catching therein. The object of such openings will be explained hereinafter. The pedal levers L, L as shown are oscillating levers and are fulcrumed on studs a attached to the bifurcations of the lower member A of the frame in front of the axle, as shown. The rear ends Z of said levers are bent inwardly so as to pass between the bifurcations of member A of the frame, and the wheel. To the end Zof each lever is attached one end of a chain or band Z which is wrapped around and its other end secured to the pulley F or F adjoining the lever. Ends Z may be perforated as at Z to enable bands Z to be adj ustably connected thereto. The front ends of said levers are curved as desired so as to bring the pedals attached thereto near the rear wheel and out of the Way of front wheel. A designate rods connected at their upper ends to the frame near the seat, and at their lower ends to the studs (1 so as to partly relieve the latter and member A of strain.

Operation: Upon the depression of either pedal the pulley to which it is connected is rotated in a forward direction. SupposingF to be thus rotated, sleeve E is similarly rotated, but sleeve E is rotated in a backward direction thereby raising lever L, and at the same time, pawls I riding up on the'teeth of ratchet J are rocked inward, thereby forcing disk K away from plate H, and the inward movement of disk K through rods it, forces disk K toward plate H, and thereby force pawlsI to engage the. ratchet J, and thus motion is imparted to the wheel in a forward direction. Upon the depression of lever L the movement of all the parts is exactly reversed except that pawls I now engage ratchet J and impart forward movement to the wheel. If the levers L, L be stopped when the pedals are in line, it will bring rods k opposite the openings 70 and rollers 70 will slip into reoesses K as indicated in Fig. 7, consequently both sets of pawls I, I can slip over their ratchets and the working parts remain at rest, the wheel revolving freely-on the ball bearings 4, 4. The pedals can then be used as rests for the feet.
