A CONSTRUCTION OF DRIVING BELTS AND WHEELS THEREFOR to be as follows:-
Year: 1885

page_text: I, PATRICK ADIE, of Broadway works, Westminster, in the County of Middlesex,
Engineer, do hereby declare the nature of my invention for "A CONSTRUCTION OF
DRIVING BELTS AND WHEELS THEREFOR to be as follows:-
"
My invention relates to a construction of driving belts and wheels to which they
are applied, in such a manner as to secure the advantages of toothed gearing with
a certain degree of elasticity and without strain on bearings such as results from
the tightening of ordinary flexible belts that drive by friction. For this purpose,
I form the belt of a strip of metal, preferably steel, corrugated transversely so as
to present teeth and intermediate hollows which adapt themselves to corresponding
hollows and teeth on the peripheries of the wheels to which the belt is applied.
A strip thus corrugated may have a plain strip of steel or other flexible material
attached to its one side by rivets at intervals, this strip giving tensile strength; or
there may be several thicknesses of the corrugated strips or of the plain strips
secured together. The corrugations, instead of extending over the whole width of
the strip, may be formed only along its middle having on each side a plain border.
The wheels to which the corrugated belt is applied may be ordinary toothed wheels
or their teeth may be formed by fixing corrugated strips such as I have described
on the peripheries of plain wheels or drums.

same is to be performed to be particularly described and ascertained in and by
the following statement:-
My invention relates to a construction of driving belts and wheels to which they
are applied in such a manner as to secure the advantages of toothed gearing with
a certain degree of elasticity and without strain on bearings such as results from
the tightening of ordinary flexible belts that drive by friction.
For this purpose, I form the belt of a strip of metal, preferably steel, corrugated
transversely so as to present teeth and intermediate hollows, which adapt them-
selves to corresponding hollows and teeth on the peripheries of the wheels to which
the belt is applied. A strip thus corrugated may have a plain strip of steel or
other flexible material attached to its one side by rivets at intervals, this strip
giving tensile strength; or there may be several thicknesses of the corrugated
strips or of the plain strips secured together.
The wheels to which the corrugated belt is applied may be ordinary toothed
wheels or their teeth may be formed by fixing corrugated strips such as I have
described on the peripheries of plain wheels or drums.
Fig. 1 of the accompanying drawings shews a corrugated driving belt, according
to my invention, applied either for driving one wheel B from A in the same
direction, or C from A in the opposite direction. Figs. 2, 3, 4 and 5 shew several
ways of constructing such driving belts. When the power to be transmitted is
moderate, a single strip of metal corrugated may be employed, as shewn in Fig. 2.
For transmitting greater power, several strips may be combined, secured to each
other by rivets at intervals, as shewn in Fig. 3.
When the wheels connected by the belt are to revolve in the same direction, the
belt may consist of a corrugated strip with a plain strip rivetted to it at intervals,
as shewn in Fig. 4-Or there may be two corrugated strips combined with an
intermediate plain strip, as shewn in Fig. 5, this belt being suitable for driving in
both directions, that is to say either B or C Fig. 1 from one motor A.
The wheels may have their cogs solid with them or affixed to them as toothed
or mortice wheels are usually made, or they may have strips of corrugated belt
fastened on their peripheries as indicated in respect to B in Fig. 1.
In order that corrugated bands such as I have described may run noiselessly on
toothed pullies, the teeth may be of soft somewhat yielding material. Thus a band
of caoutchouc, which may be corrugated, may be fixed on the periphery, or a cord
may be laced through holes bored through the periphery of the pulley as shewn in
part elevation Fig. 6 and part plan Fig. 7; or it may be laced through holes in
side cheeks as shewn in Figs. 8 and 9, the portions of the cord which present

of the corrugated band.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The construction of driving belts consisting of metal strips transversely corru-
gated, and of wheels adapted thereto, substantially as and for the purposes herein
set forth.
