SPECIFICATION forming part of Letters Patent No. 716,188, dated December 16, 1902.
Application filed May 19, 1900. Serial No. 17,227. (No model.)
To all whom it mag concern:
Be it known that I, CARLO OARLONI, a subject of the King of Italy, residing at Milan, Italy, have invented certain new and useful Improvements in Brakes; and 1 do hereby declare the following to be a full, clear, and ex act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention refers to brakes for cycles and like vehicles, specially to that descrip tion of cycle-brakes in which the brake-block is actuated by means of a screw, the brake thus remaining in position by itself when once adjusted according to the steepness of the gradients on which the cycleis to run. Some of the improvements are specially intended to be used in connection with that particular description of screw -brakes in which the brake is actuated from the handlebar by means of a flexible shaft, thus dispensing with the link connections usually employed.
In the accompanying drawings, Figure 1 is a perspective view of a bicycle. fitted with the improved brake. Fig. 2is an elevation of the actuating device, showing how the same is mounted on the handle-bar. Fig. 3 is a plan and side view of the handle-wheel by which the brake is controlled. Figs. 4 and 5 are respectively a side and a front view showing the connections between the screw and the otherparts of the brake. Fig. 6 is a side view of the crank-lever by means of which the brake-block is pressed against the wheel-tire. Fig. 7 is a transverse section of arm q in Fig. 6. Figs. 8 and 9 show in side View and cross-section, respectively, how the said crank-lever is supported by the rear fork of the cycle. Fig. 10 shows the brake-block both in front view and in plan. Figs. 11 to all refer to an additional device by means of which the action of brakes of all descripp tions controlled either by a flexible shaft or i byany other actuating device may be rendered more effective and quicker than heretofore possible, such additional'device being shown in elevation, Fig. 12; in plan from below, Fig. 13; in section on line A B, Fig. 14; in section on line C D, Fig. 15, and partially in plan from below, but in a modified position, Fig. 11.
The controlling handle-wheel a is secured at the end of a rigid shaft, which by means of a universal joint 6 causes the flexible shaft 0 to rotate on its own axis when the wheel ais acted upon by the hand of the cycle-driver. The flexible shaft 0, which by the interposition of the joint 6 is allowed to run along a side of the cycle-frame and in proximity thereof, ends in a m ultiple-threaded high-pitched screw f. The latter when caused to rotate in the direction of the arrow, Fig. 3, by means of handle-wheel a trans mits a downward motion to the nut c which cannot turn, and being connected with the rod 41. causes the crank-lever q q to turn in the direction of the arrow, Fig. 6, thus pressing the brake-block 3 against the outersurface of the wheel-tire. All connections are intended to allow of the brake being easily and quickly removed from or mounted on the cycle. The handle-wheel is secured to the handle-bar only by means of the elastic shell I), Fig. 2.
The open chamber 1', Within which the nut g is allowed to slide up and down, but prevented from turning, is secured to the cycleframe by a bush j, having an eye it, a bent lap l, entering this eye, and only one screwbolt connection on the opposite side. The nut g is connected with the rod n by means of the fork m and the douple pin 0, entering a semicircular recess 10 on both sides of the fork. This joint can be made and unmade by simply turning the rod naround the pin 0. The connections between the crank-lever q and the rod or by means of pin h, Figs. 6 and 7, as well as between the crank-lever q and the rear fork 1", Figs. 8 and 9, are also very easy to establish and to destroy.
As the motion imparted to the brake-block s when the handle-wheel a is turned in the direction of the arrow, Fig. 42,18 a positive one, it will be understood that by turning the wheel a in the opposite direction thebrake is at once released.
Another feature of my invention concerns the form of the brake-block s, Fig. 10, with channels if provided therein in order to promote the circulation of the atmospheric air, and thereby cool the rubbing-surface, as well as with a central recess u, whereby the middle part of the tire coming into contact with the soil is prevented from being subject to the rubbing action of the brake-block, which only acts on the sides of the pneumatic tire.
The additional device (shown in Figs. 11 to 15) is applicable not only toscrew-brakes fitted or not fitted with a flexible shaft, but to brakes of any kind whatever and is intended to quicken the braking action. On the handle-wheel a being turned in the direction in which the brake is released-that is to say, in a direction opposite to that shown in Fig. 3the spring I) is wound on and prevented from unwinding by the ratchet-wheel c and the pawl 01. Should it be desired to have a sudden braking take place, the pawl (1' must be acted upon so as to bring it from the position shown in Fig. 13 into that shown in Fig. 11, in which latter position the pawl d is retained by the spring 0, and springb unwinds itself at once and causes a quick and sudden rotary motion of the flexible shaft 0 in the direction of the arrow, Fig. 3, whereby the brake-block s is strongly pressed against the Wheel-tire.
Having thus described my invention and how the same is to be performed, what I claim as new, and desire to protect by Letters Patent, is
1. In a brake for vehicles, the combination, with a wheel having a flexible tire, and a brake-block havinga longitudinal central recess arranged to come opposite the tread of the tire and lateral channels extending from the central recess in each direction.
2. In a brake for vehicles, the combination with a wheel and a brake-block arranged to engage said wheel, of spring mechanism arranged to apply said brake to the wheel, means for winding said spring, means for holding said spring in its wound condition, and means for releasing said spring.
3. In a brake for vehicles, the combination with a wheel, a' brake-block arranged to engage said wheel, and a bell-crank to one arm of which said brake-block is attached, of a screw, a shaft arranged to operate the screw, means for rotating the shaft, a nut on said screw, and means connecting the nut to the other arm of the bell-crank.
4. In a brake for vehicles, the combination, with a wheel, a brake-block arranged to engage said wheel, and a bell-crank to one arm of which said brake-block is attached, of a screw, a shaft arranged to operate the screw, and a forked lever having its fork connected to a nut and its other end connected to the other arm of the bell-crank.
5. In a brake for vehicles, the combination with a hand-wheel, a flexible shaft arranged to be rotated by said hand-wheel, a screw operated by said flexible shaft, and a nut engaging said screw, of a rod connected to the nut, a wheel, a brake-block arranged to engage said wheel, a bell-crank to one arm of which said rod is connected, to the other arm of which said brake-block is attached.
In testimony whereof I affix my signature in presence of two witnesses.
OAR-LO OARLONI.
