IMPROVEMENTS IN DRIVING STRAPS OR BELTS
Year: 1884

page_text: I GEORGE HOWE, of 20 Union Square, Bury in the County of Lancaster, Currier
and Wholesale Leather Dealer do hereby declare the nature of said Invention for
IMPROVEMENTS IN DRIVING STRAPS OR BELTS, to be as follows:-
My invention relates to those driving straps which are made of narrow strips or
fillets of leather, laid longitudinally side by side and fastened together by transverso
pins or rivets, my object being by the use of a hinged portion or portions to
prevent the pins or rivets from being bent or broken.
In forming the driving strap I connect together two series of strips of leather or
other material (each strip being as wide as the thickness of the strap to be made)
placed side by side so that when finished the edges of the strips form the surface of
the driving strap, a strip at one side of each series being considerably wider than
the others. I hold the strips together by a number of rivets pins or screws the
heads of which enter conical recesses in washers which bear against the wide
strips. To connect these two series of strips together I place them side by side
with the two wide strips near to and overlapping each other and I then rivet or
otherwise secure these wide strips together, thus forming a driving strap that will
run on crowned pulleys without the pins becoming bent or broken.
When this improved belt runs on the pulleys the wide strips are upon the crown
or greatest diameter of a pulley and form a hinge whereby the two series of strips
or sido portions of the belt are connected together thus allowing a certain amount
of play and proventing the bending and breaking of the pins by the crowned
surface of the pulley.
If desired more than one hinge piece may be used and its form may be varied.
I prefer to use washers with conical recessos for the heads of the rivets as they
allow considerable play but other washers and various kinds of rivets or pins may
be employed.

page_text: I GEORGE HOWE, of 20 Union Square, Bury, in the County of Lancaster, Currier
and Wholesale Leather Dealer, do hereby declare the nature of said Invention for
IMPROVEMENTS IN DRIVING STRAPS OR BELTS, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :—
My invention relates to those driving straps which are made of narrow strips or
fillets of leather laid longitudinally side by side and fastened togother by transverse
pins or rivets, my object being, by the use of a hinged portion or portions, to
prevent the pins or rivets from being bent or broken.
In forming the driving strap I connect together two series of strips of leather or 1
other material, each strip being as wide as the thickness of the strap to be made
placed side by side so that when finished the edges of the strips form the surface of
the driving strap, a strip at one side of each series being considerably wider than
the others. I hold the strips together by a number of rivets, pins, or screws, the
heads of which enter conical recesses in washers which bear against the wide strips. 1
To connect these two series of strips together I place them side by side with the
two wide strips near to and overlapping each other and I then rivet or otherwise
'secure these wide strips together thus forming a driving strap that will run on
crowned pulleys without the pins becoming bent or broken.
When this improved belt runs on the pulleys the wide strips are upon the crown
or greatest diaineter of a pulley and form a hinge whereby the two series of strips
or side portions of the belt are connected together, thus allowing a certain amount
of play and preventing the bending and breaking of the pins by the crowned
surface of the pulley.
If desired more than one hinge piece may be used and its form may be varied.
I prefer to use washers with conical recesses for the heads of the rivets, as they
allow considerable play, but other washers and various kinds of rivets or pins may
bo employed.
And in order that my Invention may be fully understood and readily carried
into effect I will proceed to describe the accompanying Sheet of Drawings, reference
being had to the figures and letters marked thereon.
Fig. 1 is a plan. Fig. 2 a front view and Fig. 3 an edgo view of a driving strap
or belt made according to my Invention: Figs. 4 and 5 are detailed views of one
of the pins or rivets and washers which I employ and Fig 6 is'a plan and Fig. 6ª a
front view of a modification of my Invention and Figs. 7 and 8 are a plan and front:
view respectively on an enlarged scale illustrating the mode of construction.
Similar letters refer to similar parts throughout the several views.
In Figs, 1, 2 and 3 the belt is shown formed with two side pieces a, each of
which is composed of a series of strips of leather placed on edge and fastened
together, and to the wide strips of leather b by pins c, the heads of which rest in
the conical recesses of the washers d, as shown in Figs. 4 and 5, the other ends of
the pins being riveted over the washers on the outer edges of the belt; the two
side pieces, to are connected by folding the loose sides of the wide strips b over each
other, and the strips placed between them, and securing the whole together by
rivets g.
In the modification of my Invention illustrated in Figs. 6, 6, 7 and 8, I form the
side pieces a as before, of strips of leather placed on edge but I dispense with the
wide strips b and form the centre portion of the belt of two or more strips of

page_text: leather b¹ placed on edge; the washers d are in this case embedded in the inner
strips a' of the side pieces a; the strips b¹ are connected together and to the
strips a' by rivets or nails h.
The pins c and washers d may be advantageously applied to other belts of
somewhat similar construction such as link belts.
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-
1. In a driving belt, hinging the side portions of the belt to one another, substan-
tially in the manner and for the purposes specified.
2. The manufacture of driving belts, substantially in the manner herein
described and as shown with reference to Figs. 1, 2 and 3.
3. The manufacture of driving belts, substantially in the manner herein
described and as shown with reference to Figs. 6, 6, 7 and 8.
4. In a driving belt the combination with the pins c of the washers d, substau-
tially as and for the purposes herein shown and described.
