PROVISIONAL SPECIFICATION.
Improvements in Protecting the Edges of Link Belting, and in the
Means Employed therefor.
I, JOHN DENISON WALTON, of 48 St. Enoch Square, Glasgow, in the County
of Lanark, North Britain, Machinery Agent, do hereby declare the nature of this
invention to be as follows:-
This invention relates to means for preventing the heads and washers of the pins
of leather and other kinds of link belting from coming into contact with the
shifting fork or other frictional contact surface, whereby the heads and washers of
the pins are apt to get worn or knocked off. My invention has for its object to
provide a shield for the said heads and washers whereby the belt wears much longer
and the noise against the shifting fork is prevented or much reduced.
In accordance with one method of carrying out my said invention, I construct a
continuous shield for the edges of the belt of a number of stamped steel pieces.
Each shield piece has a hole at the one end to receive the pin head, the other end
of the shield piece is formed with an open slot to receive the head of the next pin ;
the same pin retaining the opposite end of the next shield piece and so on through-
out the length of the belt; the open slotted end of the shield piece allowing for the
expansion and contraction of the belt. The shield piece between its hole- at one
end and between its slot at the other end is dished out so that it is beyond the
heads of the pins and thus act as shields to prevent the pin heads from coming
against the shifting fork.
The construction of the shields may be varied in many ways, for example
both ends of the shield piece may be open slotted or they may be provided with
slotted holes.
Or the shields may be constructed of metal pieces having their ends bent inwards
or doubled up, the said doubled up ends having the holes or slots to receive the
pins, the outside of the shield pieces thus forming a cap over two pins.
Or the shield pieces may have their edges, at the top and bottom of the belt,
turned up so as to constitute flanges for the protection of the pin heads; the said
shield pieces having slotted ends to receive the pin heads; or the ends of the pins
may be bent over and so retained between the flanges instead of rivetting the pin
heads, or providing the pins with heads at all. The said construction of shields
might be cast.
I may employ any other analogous forms of the shields, whereby the pin heads
and washers are kept out of contact with the shifting fork.

Improvements in Protecting the Edges of Link Belting, and in the
Means Employed therefor.
I. JOHN DENISON WALTON, of 48 St. Enoch Square, Glasgow, in the County
of Lanark, North Britain, Machinery Agent, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
This invention relates to means for preventing the heads and washers of the pins
of leather and other kinds of link belting from coming into contact with the
shifting fork or other projection whereby the heads and washers of the pins are
apt to get worn or knocked off. My invention has for its object to provide a
shield for the said heads and washers.
"
Figure 1 is a sectional plan of my said invention.
Figure 2 is an edge view of same.
Figures 3 and 4, are similar views of a modification hereinafter referred to.
Referring to Figures 1 and 2 I construct a continuous shield for the edges of
the belt of a number of stamped steel pieces A. Each shield piece has a hole a
at the one end to receive the head of the pin B; the other end of the shield piece
is formed with a slot a¹ to receive the head of the next pin; the same pin retaining
the opposite end of the next shield piece and so on throughout the length of the
belt; the slotted end of the shield piece allowing for the expansion and contraction
of the belt. The shield piece between its hole at one end and between its slot at
the other end is dished out as shown in Figure 1 so that it is beyond the heads of
the pins and thus shields the pin heads from coming against the shifting fork.
As shown in sectional plan and edge view Figures 3 and 4 respectively I may
form the metal piece or links with a flat raised portion a², with slotted hole a¹ at
the one end; and with the other end formed with a countersunk portion having a
hole a for the reception of the head of the rivet B; the leather or other link
being correspondingly countersunk at this part.
It will thus be seen from the foregoing examples that the heads (and washers if
any) of the pins are entirely protected.
The details in the carrying out of my said invention may be varied in many
ways, for example I may form both ends of the metal pieces or shields with open
slots; or both ends with slotted holes. Or the metal pieces may have their edges
at the top and bottom of the belt turned up so as to constitute flanges for the
protection of the pin heads; the said shield pieces having slotted ends to receive
the pin heads; or the ends of the pins may be bent over and so retained between
the flanges instead of rivetting the pin heads, or providing the pins with heads at
all. The said construction of shields might be east.
I may employ any other analogous forms of the shields, whereby the pin heads
and washers are kept out of contact with the shifting fork.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
In leather and other link belting, providing the edges with stamped steel shields;
or any mere modification of the same; substantially as and for the purposes
herein before described and shown in the accompanying drawings.
