This "a an outline description Of the
modern s,idinS seiectiye transmission,
which was first introduced by Panhard
a I,avassor in the early days of the
| automobile era and which IN spite Of
4 its obvious shortcomings has never been
supplanted and 10 the tyne in general
| use to-day OF course the gearset Of
I the present is far refined over the crude
creations OF the early days, but its
fundamental crudity is still there.
| While the sliding selective gearset, as
described, Is the predominant type In
the field, there are other forms of trans
| missions In use. There Is the planetary
! gearset, which Is used In the Ford car,
| and consequently on the score Of mere
| numbers Is an important factor IN the
situation The friction gearset, once
| popular. Is not used to-day. and the
| magnetic transmission Is used on but
| few high priced vehicles because OF its
| costliness. In the truck field we find
the constant mesh selective gearset in
| considerable use. but this type has not
made any Roadway in the passenger car
I field II we add to this the direct con-
| nected transmission as used in the
steamer We have completed the list.
| The reader will note that OF the types
| mentioned only the conventional sliding
| selective and the planetary as used in
the Ford are employed In modern auto y
! mobile design.
| 1t is rather remarkable that the one
| type of transmission that may lay
claim to really satisfactory simplicity
| of operation, the friction set has
\ passed out OF use altogether The fric-
| ton set consists of two discs at right
angles 10 each other One Of these Is
driven by the engine and is usually OF
copper, while the other is of some sort
of fibre composition and is mounted on
| a shaft extending across the frame and
| connected with the driving wheels nv
