APPARATUS FOR TRANSMITTING ROTARY MOTION.

SPECIFICATION forming part of Letters Patent No. 587,713, dated August 10, 1897. Application filed December 11, 1896. Serial No, 615,384. (No model.) Patented in England May 16,1896, No. 10,523.

To aZZ whom it may concern.-

Be it known that I, EDWARD KEN WORTHY DUTTON, asubject of the Queen of Great Britain, residing at Arden, Harrogate, county of York, England, have invented certain new and useful Improvements in Apparatus for Transmitting Rotary Motion, of which the following is a specification.

The invention has been patented in England, No. 10,523, May 16, 1896.

The invention relates to frictional rotarymotion-transmitting apparatus. A frictionwheel and disk have been used for the purpose for many years, but have had the disadvantage of being limited in transmitting capability. To increase such capability, I combine two or three friction-wheels, which are mounted close to one another, on a common axis and are connected by means of balance-gear, so that each wheel can revolve at a speed due to its distance from the disk center, and for some purposes I combine two sets of such combined friction-wheels and connect such sets by means of balance-gear.

In the accompanying drawings, which are illustrative of my invention, Figure 1 represents two friction-wheels connected by means of balance-gear. Fig. 2 represents three friction-wheels similarly connected. Fig. 3 shows a combination of two sets, each comprising, two friction-wheels. Fig. 4 shows a combination of the two wheels in Fig. 1 with a disk. Fig. 5 shows a combination of the three wheels in Fig. 2 with a disk. Fig. 6 shows a combination of two sets, each comprising three friction-wheels, and also shows the application of the same to a disk.

In Fig. 1, A A are two friction-wheels which are mounted to revolve loosely upon a shaft 13 and are provided with tires of leather or other suitable material. Each wheel is formed in one piece with or secured to a bevel-gear O or O, and the two bevel-gears mesh with an intermediate bevel-gear D, which is mounted to revolve upon a stud E, carried by a hub or block E, which is fast to the shaft B.

In Fig. 4 the set of two friction-wheels is shown in combination with a disk I, the wheels driving the disk or the disk drivingthe wheels, as may be required. It will be seen that if the two wheels A A revolve at the same speed the shaft B will also revolve at the same speed,

the two speeds of the wheels-as, for example, if one wheel revolves at four hundred and the other at three hundred and sixty the hub E and, as a consequence, the shaft B will make three hundred and eighty revolutions per minute, both wheels revolving in the same direction. The two wheels A A are made of a dished form, so as to bring the two tires A A near together. The closer the said tires are brought to each other the less will be the difierence between the speeds of the two wheels, so that the wheels may run at a high velocity while the gear D is revolving slowly.

In Fig. 2 the connection of the two wheels A A is the same; but a central wheel A is added, such wheel forming part of, or being attached to,'the hub E which carries an intermediate bevel-gear D, which meshes with gears C 0 fixed to the two wheels A A The tires of the'three wheels are brought close together, as in the case of thetwo wheels in Fig. 1. In the example the two outer wheels A A will revolve at different speeds and the central wheel A will revolve at a speed which will be the mean of the speeds of the two outer wheels, each wheel transmitting its proportionate share of the driving strain.

Fig. 5 shows the set of three friction-wheels in combination with a disk J. When the disk would be the driver, the two outer wheels A A would transmit driving power through the intermediate gear D to the central wheel A and the said gear D would revolve to suit the differing speeds of the two outer wheels.

In the ordinary use of a single frictionwheel driving or being driven by a disk it is usual to try to obtain transmitting capability by making the periphery of the friction-wheel wide, so as to increase the hold upon the disk; butI consider this to be a mistake' for thereason that only the central part of the width of the wheel can revolve at the correct speed,

one edge revolving too fast and the other too slow, so that much friction, wear, and loss of power are entailed. For this reason I use wheels having comparatively narrow periphconcert.

cries, and by combining two or three together obtain greater efficiency than if a single wheel equal in width to the three combined should be used.

In Fig. 3 two sets of friction-wheels, each comprising two wheels combined, as in Fig. 1, are connected by balance-gear, so as to act in In this example the hub E is not fast to the shaft B but is connected by means of a sleeve F,which extends through the wheel A with a bevel-gear G, the said connected parts revolving loosely upon the said shaft. The two bevel-gears G G are connected by an intermediate bevel-gear H, which is mounted upon a stud 11, carried by a hub or block E, which is fixed or formed upon the shaft 13 The four friction-wheels can thus act in concert upon or be acted upon by a disk.

Fig. 6 shows a combination of two sets of friction-wheels with a disk K. In the example each of the two sets M N comprises three wheels formed and connected as inFig. 2, with the exception that the hub F. is connected with thebevel-gear G in Fig. 6 by means of a sleeve F, as in the ease of the combination shown in Fig. 3.

In Fig. 6 one set of friction-wheels is on one side of the axis of the disk and the other set on the other side. In such a case when both sets would be equidistant from the disk-axis no motion would be comm unicated to the shaft B supposing the disk to be driving; but if the shaft were to be moved in the direction of its axis or if the combination of friction-wheels and gears were to be moved along the shaft in either direction the said shaft would be revolved, the speed increasing in proportion to such movement. It will be obvious that more than one intermediate gear may be used to connect the gears C G, 0 C or G G.

In Fig. 6 two intermediate gears H H are used. The gears G G and H 11 may be toothed or frictional, as considered to be most suitable.

I am now aware of the combination of two friction-wheels described in the specification of F. XV. Gordon, to whom Patent No. 467,503, dated January 26, 1892, has been issued. In the drawings attached to such specification appear two friction wheels connected by bevel-gears in a similar manner to the two sets of friction-wheels which appear in Figs. 3 and (3 of the drawings hereto, in combination with two disks, or it might be with one disk, and I therefore do not claim such combination nor any similarcombination, excepting when each of the two so-termed brushwheels is represented by two or three friction-wheels connected together in the manner set forth herein, whereby four or six drivingcontacts are obtained with a single disk instead of two only, or eight or twelve contacts if two disks were used, the improvement resulting in a greatly-increased capability for transmitting power, or excepting when the two friction-wheels are dished, so as to bring their peripheries close together, but not touching, and so as to inclose the bevel-gear, as in Fig. 1, and in addition when the combination is used, together with a revolving disk, in such a manner as that the two friction-wheels shall revolve in the same direction.

I claim as my invention- 1. In disk and friction-wheel gearing: three friction-wheels having a common axis, the central wheel of the three being fixed upon a shaft, an intermediate bevel -gear carried thereby, gears upon the two outer wheels meshing with said intermediate gear, the said outer wheels being loose upon the said shaft and a disk, all three friction-wheels being in working contact with said disk, substantially as set forth.

2. In disk and friction-wheel gearing: the combination of the wheels A, A mounted loosely upon a shaft, gears 0 C an intermediate gear D, the latter mounted on a radial axis in a third wheel A fixed to'the shaft and a disk J, the tires or peripheries of the three wheels, being in working contact with said disk J, substantially as set forth.

3. In disk'and friction-wheel gearing: the combination of four friction-wheels having a common axis, arranged in two sets each comprising two wheels,bevel-gears connecting the same, an intermediate gear in each set connected with the intermediate gearin the other set, a third set of bevel-gears forming the 0011-. nection, the intermediate gear in such third set revolving upon an axis carried by a part fixed upon the shaft upon which the entire combination is mounted, substantially as set forth.

4'. In disk and friction-wheel gearing: the combination of six friction-wheels, having a common axis, arranged in two sets','each comprising three wheels,-a bevel-gear carried by the central wheel in each set, gears 0n the two outer wheels in such set meshing with the bevel-gears, the two center wheels, a set of bevelbalancegears connecting the two center wheels in the two sets, the intermediate gear in such balance-gears revolving upon an axis radial from the common axis of all the six friction-wheels, such radial axis being carried by a part fixed upon the shaft upon which the entire combination is mounted, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.

EDWARD KENWORTHY BUTTON.
