For a better understanding of the invention,, and to show more clearly how tlie 65 same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings in which:
Figure 1: is a partial sectional’ view of a lever system according-to the present invent 70 tion; Figures 2, 3 and 4, are partial sectional views, on a larger scale, showing the noiseproducing device of the lever system illustrated in Figure 1 in different angular 75 positions; Figure 5 is a perspective view of part of’ the noise-producing’device shown in Figures, 1 to 4; Figure 6 is a partial’ sectional view of the’ 80 lever shown in Figure 1 mounted on, a sect tion of a-bicycle frame; Figure 7 is an elevation of an embodiment of the invention comprising an apparatus with’ two contril levers; 85 Figure 8 isi a perspective view of’ elements of the control levers shown in Figure 7; and Figure 9 is a partial, sectional view illu strating the mounting of thile’ contro P levers 90 shown in Figure 7 on a bicycle frame; Figures 1 to 6 show a control lever in’ accordance with the invention An axle 1 has parallel flat surfaces such ag l for theengagememn, and, angular, location, of a 95 toothed wheel 2 provided’ with’ a bore 2 a corresponding to the’ axle 1 A control lever’ 3 includes, a bore 3 a’ for’ the axle 1 ‘to pass through and; oni one face; a eiam1 568 650 can vary and, at the extreme, the shoe need only have one control tooth.
The toothed wheel may comprise as many teeth as there are pinions on the free wheel, so that every clatter corresponds to 70 a change of gear; this is with a shoe having one or several teeth Alternatively, there may be employed a toothed wheel which at regular intervals has larger tooth spaces corresponding to the sole tooth of the shoe 75 and indicating, by a different sound, changes of gear Furthermore several shoes could be used if desired.
The mechanism could be reversed, i e.
providing a lever with a toothed rim, rota 80 ting relative to a toothed shoe or shoes located movably on the lever’s axle.
Illustrated in Figures 7, 8 and 9 of the drawings is an apparatus with two control levers, with their respective noise devices, 85 for the front and rear gear changes on a unit fixing them to an element Cl of a bicycle frame.
The assembly comprises an axle 5 which passes right through a block 6 and whose 90 ends, having parallel flat pieces 5 a, project on each side of the block 6 The block 6 forms a semicircle about an axis orthogonal to the passage 6 a Thus together with a half collar 7 the block can be 95 clamped to the bicycle frame The half collar 7 rotates about an axle 8 on one side of the block by means of a folded back section 7 a which is formed around the axle 8 on which is mounted the head 9 a of a 100 screw 9 engaged in an orifice in the block and cooperate with threaded hole Sb of the axle 5 On the opposite end of half collar 7, a locking screw 10 passes through an orifice in the block and likewise cooperates 105 with a threaded hole 5 c in the axle 5 which is thereby held securely in the block.
The end faces of the block have polygonal bearings 6 c for the fixed mounting of plates 11 provided with projections ll 110 The projections 1 la together with projections 12 a on control levers 12 act as angular stops On the same side as the projections 12 a the levers receive the toothed wheels 2 integral with the axle 5 in cham 115 bers 12 b by means of their central orifices 2 a shaped like the flat ends of the axle 5.
Cavities 12 c open into the chambers 12 b to receive the toothed shoes 4 with flexible tongues 4 b 120 On their opposite faces, the levers also have chambers 12 d for housing rings 15 with orifices 15 a corresponding to the flat ends of the axle 5 The levers are locked elastically and in an adjustable manner on 125 the axle by means of screws 16 screwed in the ends of the axle and whose driving heads 17 bear on the spring washers 18 and contact washers 19 which have a flat opening 130 ber 3 b (or housing) for the toothed wheel 2.
A cavity 3 c opens into the chamber 3 b and receives a shoe 4 whose face facing the toothed wheel 2 has teeth 4 a along an arc of a circle corresponding to the radius of the toothed wheel 2 The teeth 4 a are of the same pitch as those of the wheel 2, whereas on the opposite face of the shoe flexible tongues 4 b are directly moulded, these tongues being spaced from the shoe but linked to it by a centre section At their ends these flexible tongues 4 b bear on the roof of a cavity 3 c when the teeth of the shoe penetrate into the spaces between the wheel’s teeth (see Figure 2).
The tongues overlap the length of the shoe and their ends engage in clearances 3 d provided in the cavity.
It can be observed that the ends of rear face 4 c are sufficiently spaced for the flexible tongues to operate freely without any risk of touching when compression is greatest.
It should be noted that the chamber 3 b is dimensioned so that the shoe 4 may be housed, there with play at least equal to a half tooth or a half pitch, but not much above this, in order to increase the noise effect by promoting the clatter of the shoe teeth on the sides of the wheel’s teeth at the moment when the shoe moves back down again into place on the wheel.
It is clear that when the lever 3 is moved angularly, for instance in the direction of the arrow Fl, Figure 3, the teeth of the shoe 4 slide on the teeth of the wheel 2.
The shoe 4, housed with play in the cavity 3 c tilts when recoiling elastically counter to the tongues 4 b When the teeth of the shoe 4 reach the tops of the wheel’s teeth (Figure 4) the shoe is pushed strongly by the tongues 4 b so that its teeth take up position again in the spaces between the wheel’s teeth With this action the teeth of the shoe 4 clatter on the sides of the wheel’s teeth producing a noise which is more audible the larger are the teeth and the greater is the number of the teeth of the shoe, It can be seen further that the faces located on each side of the shoe’s teeth are disengaged, the end teeth being truncated if need be so that no side of the teeth of the shoe and of the -wheel are in contact in a position opposed to successive disengaging and engaging of the shoe in the teeth of the wheel.
In the illustrated embodiment, the shoe 4 -and, the flexible tongues 4 b are made in a single piece, moulded from a plastics material the tongues 4 b can be replaced by sp-ini c means which is independent of the shoe and, is made of a different material Likewss the -number of teeth on the shoe 1,568,650 said shoe and disposed on a side of said shoe opposite to the teeth of said shoe, it being possible to engage said tongues in 60 clearances of the chamber which restrains said shoe.
7 A lever system as claimed in claims 3, 4, 5 or 6, wherein said shoe is movably mounted in the chamber and said toothed 65 wheel is secured to said axle.
8 A lever system as claimed in claims 3, 4, 5 or 6, wherein said toothed wheel is secured to said lever and said shoe is movably mounted in the chamber 70 9 A lever system as claimed in claim 3, wherein one or both of said toothed wheel and said shoe are formed of a plastics material.
A lever system as claimed in any 75 one of claims 3 to 9, wherein said lever system is adapted to operate a gear change mechanism and wherein the pitch of said shoe’s teeth and said wheel’s teeth are chosen to correspond to the discrete lever 80 movements required for each gear change.
