E. K. F. OTTO in LONDON. Innovations to Velocipedes.

Patented in the German Empire on October 2nd, 1879.

Fig. 1 and 2 of the accompanying drawings show the side and front view and Fig. 3 shows a Grundrifs of my improved Velociped. FIG. 4 is an intersection along the line AB, FIG. 2.

A curved or right-angled cranked axis gg " ¹ is provided with two wheels α , which carry rubber rings b . In or above the horizontal and slightly behind the vertical center line an adjustable seat jj 'is attached, which is lifted with the aid of a screw and nut / ⁵ or can be lowered, while for avoiding the percussions springs y ^{2/3/4 is} mounted under the seat and are fixed to the axis, that the seat can assume any desired inclination. double springs can, depending on the weight of the traveling ends, next be arranged with each other.

In order to make it easier for the driver to maintain his balance, straps q 'are attached over the step rails q so that he can lift the curvature axis and thus the whole frame with his foot. The straps are also arranged so that the foot can be pulled out with ease.

Cords or pulleys c are attached to the wheels, over which cords, belts or chains P run; the connecting rods k go down from the axis on both sides of the seat. They are square at the top and round at the bottom, and sliding bushes r are pushed onto the lower round parts, which take up the curved ax t , which passes through it so far that the cord discs / can be wedged at the outer ends. If the curvilinear axis is moved by means of the tread bars, the movement is transmitted to the drive wheels α through the disks /, the cords P and disks c. The springs 0, which are regulated by the screws m ³ and press on the bushes r , keep the cords in the appropriate tension.

5, 6 and 7 show the cross-section, outline and side view of a sliding bushing r \ u is the opening for the curvilinear axis, ν the opening for receiving the connecting rod k (laterally oval in order to have play for the control); w is used to hold the control rod k ² , - while χ is a lubrication hole.

The control rods k " ¹ , Fig. 4, are connected to the sliding bushes r and are held together by sleeves with internal right-hand and left-hand threads, so that when the sleeves are rotated in one sense or the other, the rods can be lengthened or shortened The ends of the sleeves are tapered on the outside, are cut open and have a conical thread on the outside, which receives the nuts k * in order to be able to fix the sleeves in their position. and can be moved down. By raising or depressing the same bottom line wheel is raised or lowered, the cord so slack or taut. m Suitable guides', m in the cans sitting out the cords when they go limp.

The brake shoes / are firmly seated in the brake blocks P, which can slide freely up and down on the connecting rods k. The point of attack is under the discs c. These brakes are connected by round iron bars ί ί · to the control levers e and to the brake and control levers /, the latter being attached in any suitable position and held in it by springs / 'and attachment / ² .

The handles of the control levers e sit loosely and can be turned so that they press down the brake lever / by means of a latch, pull the brake shoes / against the discs c and thus slow down the movement when driving downhill.

When one or both levers e are raised, one or both of the drive cords becomes slack and the brake is applied to the wheel in question. If you want to moderate the speed even more when driving downhill, one or both brake levers / are pressed down slightly.

The rods ί ί 'take down the springs s ² s ³ , which are held respectively by attached nuts. can be regulated and which moderate the effect of the brakes. s ⁴ is a counter spring pushed onto the rod ί, which pushes the brake shoes / off the cord disc c when the brake lever is in the rest position.

By attaching a long, rearward-going bracket h to the axis g , a

Claims (4)

Auxiliary brake formed. The bracket is provided with a board / ι ¹ for buckling the luggage and with a roller or wheel / ι ² . This roller does not usually touch the ground, but only when the rider leans backwards. The machine is then braked quickly, even when driving downhill, since the main weight rests on the roller h ² and the driver can use all his strength to bring the brake shoes into effect. Patent claims: i. The improved position and arrangement of the seat in combination with the tread strips, whereby the perfect balance can be maintained and driving over uneven terrain and over obstacles, which up to now have been very difficult for Velocipedes, is made much easier and which exists a) in the adjustable seat, which is in or above the horizontal and something behind the vertical center line, thereby maintaining the rider's balance and much smaller wheels can be used, making the machine significantly lighter; b) in the springs / ² , of which one or two can be used side by side and which, depending on the weight of the rider, are reinforced and regulated by spiral springs J ³ J * and through bolts with nuts, with the seat J resting on them can assume any position that is most comfortable for the driver, as the seat goes down significantly more at the front than at the back and thus cannot press the edge uncomfortably; c) in springs J ³ which, owing to their special shape, have great elasticity and strength, since they are open at the front, while they are held together by the above-mentioned bolts and nuts. 2. The improved arrangement of the control device, whereby the drive wheels can be instantly transformed into control wheels and vice versa, which consists of the following parts: The brake shoes / fixed in the brake blocks P, sliding on the connecting rods k , which when the control lever is raised, e Round iron bars s with spiral springs r 'for later disengagement of the brake shoes / against the discs c . This movement of the control lever e, which presses / 'against c , simultaneously lifts the corresponding treadle disk /, whereby the cord / ² slackens while the speed of the corresponding drive wheel is braked, thus converting such a wheel into a steering wheel. 3. The improved arrangement of the braking device, which consists of: a) in the brake lever /, when depressed, the rod s ^l presses the brake shoes / against the disc c ; b) in the spiral spring s * on the rod i ¹ , which moderates the pressure of the brake, and c) in the spring / 'which returns the lever / to the rest position when you cease to need it. 4. The improved arrangement for shortening and lengthening the control rods, consisting of sleeves k ^l with internal right-hand and left-hand threads for regulating the rods k * and which allow the handles / to assume a more vertical position.
