MECHANISM Filed sept. 14. 192s 2 sheets-sheet 2 Patented Dec. 15, 1931 PATENT OFFICE JOHAN DIRK CABLEY, OF THE HAGUE, NETHERLANDS mmcmimsm Application led September 14, 1929, Serial No. 392,659, and in the Netherlands September 28, 1928.

The invention relates to a. mechanism that may be employed for thel conversion of oscillations, for example electric, mechanical or acoustic oscillations, into a rotary or reciprocatory motion.y The mechanism can be employed for the drive of clocks, for the motion of advertising apparatus or for other purposes.

The mechanism according to the invention is characterized in that the motion is called into existence by the alternating increase and decrease of the reciprocal distance between two bodies, andy by the influence of oscillations or impulses, which are communicated to one of the bodies or to both. Hereby these bodies are held apart from one another by f the `resilient organs, orby a resilient substance, which` possess the properties during this alternating increase and decrease of the Zoreciprocal distance of the bodies effecting a relative motion of these bodies parallel to their surface of contact.

AThe intermediate layer ,between the two bodies can for exam le be formed by a plushlikel textile material) with pile-wires or by a brush surface or the like formed' for example by raised metal threads.

For the production of a rotarymotion of one of the above mentioned bodies or of'both in accordance with the invention, the' resilient organs (pile wires or brush wires) of the intermediate layer may be so disposed, that as a result of the oscillations the bodies produce a relativer rotation.

According to the invention the movable bodies can be constructed of a plurality of parts and these single parts can correspond to diiferent numbers of oscillations, whilst the organs of theA intermediate layers are so disposed', that ink changinfr application to different numbers of oscil ations (frequency) both parts produce a tol and fro relative motion.

The invention is illustrated in the drawings by Way of examples ofV construction.

In Figs. 1 and 2 the basic idea, to which thle1 inventionA relates, is shown diagrammatica y.

Fig. 3 shows diagrammatically an apparatus for the employment' of sound waves for the production of a rotary motion or for the registration of acoustic oscillations, Which then may set in rotation a circular plate.

4ig. 4 shows diagrammatically an apparatus for inclusion in an alternating current circuit, in which electric oscillations by means of an electromagnet act on a membrane or plate which as a result rotates on its axis.

` 5 shows a modified' form of the apparatus according to Figure 4.

Fig. 6 shows the side view of the mechanism according to the invention as applied to the drive of a clock.

Fig. 7 is a rear View of the same mechanism appertaining to Figure 6.

f In FigureV 1 a membrane designated 1, rests on ay supporting surface- 3 by means of an intermediate layer of alterable thickness.

The intermediate layer can be secured to the supporting surface 3 instead of to the membranel 1 orcan rest thereon.

The membrane lis rotatable aboutk a vertical axis. The intermediate layer is formed of a resilient material or a resilient organ, in bothcases of such a kind that in the consecutivedecrease-or increase of the reciprocal distance between the parts 1 and 3 a motion of'theseparts relative to one another but parallel to the surface of a contact is produced. For the intermediate layer suitably a material such as plush (mock-velvet) can be employed, which is provided with pile-Wires, which are directed at a slope with regard to the surface of the textile material. In order to make clear the operation only a single brush wire or pile wire 4 is shown in Figures 1 and 2.

The membrane first occupies a position 1 (Fig. 1). On arrival at the membrane oscillations or forces now operate so that the distance between membrane 1 and the rsupporting surface 3 is alternately increased and decreased. The lower end position is designated by 1 and in Figure 2 in a full line.

By the transfer of the membrane from position 1 to position 1 firstly the pile wire 4 (Fig. l) is rotated about its lower end b with which it makes contact with the surface 3, and changes from the position a' to the position b a, which is shown 1 in full line in Fig. 2 and in Fig. 1 in dotted line. 'Hereby its'results as appears from the horizontal projection inFig. lthat the membrane is rotated through an angle a. It returns, however, into the upper position 1, 1'.

F ig. 2) as aresult of the uninterrupted impulses operating on the membrane this play is repeated. As Va result the membrane, as has been shown is set in rotary movement so that under the influence of thisA rotation it has produced a rotation of an angle a and about its axis, after it has returned to the starting position shown in Fig. 1. Y

In Fgure S an apparatus is illustrated whichserve's' for making sound oscillations usablefor the productionof a rotary motion or to indicate sound waves. 1 y

Here a-'cireular ,membrane lis rotatably disposed about a vertical axis 5, which is so disposedrin sockets 6, 7, orfana bent member 8 and the supporting surface 3, so that a certainplay of theaXis is possible in tlieaX- j ial direction. The circular memberl 1 rests on the base surface 3 by means of an inter- Vmediate layer, which is provided with raised small pile wires 4. The pile wires l are raised somewhat sloping and tangential around the Vcircumference of the circular plate-shaped member 1, so that the plate ,1, by the operation of the sound waves intercepted on itcan be putin rotation. The apparatus can be employedfor measuring the strength of sound oscillations orof sound volume. It canalso serve for the indication of sound waves, furthermore forsound waves of a certain nuinbei' of'oscillations to which in this` ease the CTI membrane 1 must be tuned. V

Fig. t shows diagrammatically ani apparatus `in which an alternatingcurrent is applied. An electromagnet 9 is connected to anr alternatingcurrent circuit by the ends 10 `and 11 of tlie winding of the magnet. The bipolar magnet acts onl a membrane l which is rotatable about a-shaft 12. The

membrane 1 is attachedgto-the shaft 12 by means of a leaf spring 13,.of whichthe outer ends are secured tothe membrane 1 andthe inner ends are secured to the shaft 12. The

connection is so formed, that the membrane 1 can perform oscillations I perpendicular to itsv own plane independently of the axis 1 2.

The membrane 1 is supported by the inter# mediate layer 1- in a resilient manner ontlie supporting surface 3, which inthe manner above described can be formed of a textile material or of a material with pilewires (illustrated in Figure l only partlyand with dotted lines) Vraised in a direction round the circumference of the membrane.

The membrane 1 consists of a-magnetizable material, so that the How of magnetic force to the magnet isvrclosed Yby the membrane. lf the electromagnet be connected now to a source of alternating current the membrane a result isv put in'oscillation, Yso that it produces in the manner above described at the same time a Yrotation about its aXis 12.

The` form of construction according to Figure 5 differs 'fromL that according to Figure l only so'far that in this case a unipolar magnetV 111 is employed which forms at the same time the lower socket 15V for the Vshaft 12. The membrane 1 is in like man ner as in Figures secured to the axis 12 by means of the spring 13 and is supported on Athe supporting surface 3 by means of the intermediate layer formed by the pile wires Vor brush, which in this case areiformed on Constructed for-a, rotary motion the mov@ 'able part can also execute a rectilinear motion with Vregard to thesupporting surface in whiclicase the pile wires of the intermediate layer are raised in a single direction. The movable can also be formed'in two ,or` more-parts and Veach of these parts corre-V spond to another `number of oscillations,v wherein the pile wires are so disposed, that by changing vapplication to different ,num-

bers or oscillations the two partsy execute a' rectilinear motion relative vto keach other. Furthermore the apparatus can be so constructed,V that indeed according ,to the number of Voscillations the movable: partis moved'in a certain direction or in an opposed direction to the fixed part. I

In the construction according to Figures 6 and 7 themagnetic system which consists of two windings 101 and 102 connected one behind-the other or side by side, secured to a frame 103, which is secured to a footplate 105 by means of a standard 104. The magnetic system 101, 102, isvfed with alternating cur rent and can` for example be included by means of the closure clamps 10G and 107 in n an alternating Vcircuit suitably the usual 1Lighting distribution system. The magnetic system acts on an armature108, which has the form of al flat circular plate.v This armature 108, is securedv by means of a leafspring 109 and screws'110 and 111 to a vertical shaft 112 and suitably by connection to a resilientV coupling 113. The shaft 112 is disposed in two plates 126 and 127, which form y magnetic winding 101v andV 102.

Va plate 130, which is disposedunder the The magnet-armature 108 is formed of circular shape and on the lower side is provided with small brushes or strips of plush 131, which are so disposed, that'as a result of the vertical oscillations which the armature 108 receives under the influence of the magnet windings 101 and 102, this armature 108 undergoes a rotation about the vertical axis 112 with which it is coupled. As a result of this the worm wheel 117 is set in rotation by the worm 116, which rotation is transmitted to the axle 118 and by the gear wheel system 119/ 122 to the hub 123.

The coupling 113 consists of a drum 114, which is connected with the leaf-spring 109 and a spiral spring 115, which is coupled by its inner end with the shaft 112 about the outer circumference of which the inner wall of the drum 114 slips. Normally the motion of the rotating armature 108 is transmitted to the shaft 112. However, should the resistance be too great the spring 115 slips with relation to the inner wall, of the drum. The shaft 112 is provided with a worm 116, which is in engagement with a worm wheel 117 secured to the shaft 118, which in the usual manner carries the minute hand (not shown in the drawings). The gear wheels 119, 120,V

121 and 122, serve to drive the hub 123, which is mounted on the shaft 118 and carries the hour hand illustrated. The dial is indicated at 124. It is secured to the standard 104 by means of screws 125.

A regulating screw is indicated at 132, which is screwed into the upper plate 127 of the magnetic system, and which is constructed as a lower bearing for the shaft 112.

If the magnetic system 101, 102 is submitted to the action of a current by connection to an alternating current circuit, the circular armature 101 is set in oscillation by the influence of the attraction by the magnets 101, 102, on the one hand and the influence of the spring 109 on the other hand. Thereby the plush strips or brushes 131 are alternately pressed together and again given freedom. During the pressing together, that is to say if the armature is attracted this has as a result a rotation of the plate 108 about the shaft 112. In the unit of time the plate 108 thus receives a great number of impulses, in the same sense of rotation so that it is rotated with a uniform velocity and thereby drives the shaft 118 by means of the worm transmission gear.

What I claim is 1. A mechanism for transforming oscillations into a rotary movement comprising a resilient member being of the nature of pieces of pile fabric or brushes and having groups of bristles or fibres projecting therefrom, an axially oscillating serrated disc adapted for rotary movement, .and a fixed plate parallel 35 to said disc and on which the pieces of pile fabric or brushes are secured for contact of the bristles with the serrated surface of the movable disc, the bristles having a predetermined inclination with respect to the plane of the disc, whereby a rotary movement is imparted to said disc as the disc approaches the fixed plate.

2. An electromagnetic driving mechanism, comprising a rotatable magnetizable disc armature operating in an alternating magnetic field and oscillating axially under the action of the said field, in combination with resilient members secured to said disc, said resilient members being of the nature of pieces of pile fabric or brushes, the fibres or bristles thereof being inclined to the surface of said disc and disposed to contact at their free ends with said surface, whereby a rotary movement is imparted to the latter as the distance between the disc and the said fixed surface is alternately increasing and decreasmg.

3. A mechanism for transforming oscillations in a. rotary movement, comprising a pair of parallel discs, one thereof being adapted for axial oscillations with respect to the other disc, and a resilient member of the nature of pieces of pile fabric or brushes carried by one of the discs and composed of groups of bristles or libres projecting therefrom, each group having a predetermined inclination with respect to the planes of said discs and engaging at the free ends of the bristles with the surface of one disc, whereby axial oscillations of the one disc cause the bristles to impart rotary movement to one of the discs.

In testimony whereof I aflix my signature.
