IMPROVEMENTS IN PULLEYS to be as follows:
Year: 1884

page_text: I, OLAF RYE OLSEN of Indianapolis, Indiana, United States of America,
Machinist, do hereby declare the nature of said Invention for "IMPROVEMENTS IN
PULLEYS to be as follows:-
"
My Invention relates to the class of metal pulleys having divisible rims, and
comprises the improvements hereinafter described.
In the accompanying Drawing
Figure 1 is a sectional view of a pulley constructed according to. this Invention.
Figure 2 is a side view of the saine.
Figure 3 is a sectional view showing lugs on either side the inner rim for
strengthening the pulley and
Figure 4 is a side view of the same.
The rim is made preferably of rolled or sheet metal, having a joint at j. The
hub h, spokes 8, and inner or secondary rim are all cast in one piece. This
secondary rim may be made of any width desired, or may be cast with lugs or
projections in the sides, as indicated in Figure 3, thereby ensuring great strength.
In this way the joint in the outer rim may be reinforced by placing one or more
of these lugs on the inside of the rim 7, and over the joint.
The lugs being integral with the secondary rim ¹ may readily be adapted to
cover the joint or any other part of the outer rim as will be seen.
This secondary rim, when properly placed and. fitted, is riveted to the outer rim
by rivets 1, 2.
This form of construction ensures a strong, simple, and light pulley capable of
being run at high rates of speed without fracture or giving way.
The hub aud secondary rim may be made in two parts if desired, and bolted
together before being set into the outer rim.

page_text: I OLAF RYE OLSEN, of Indianapolis, Indiana, United States of America,
Machinist, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
PULLEYS 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 that class of metal pulleys having divisible rims and
comprises the improvements hereinafter described.
In the accompanying Drawing
Figure 1 is a sectional view of a pulley constructed according to this Invention.
Figure 2 is a side view of the same.
Figure 3 is a sectional view showing lugs on either side the inner rim for
strengthening the pulley, and
Figure 4 is a side view of the same.
The rim is made preferably of rolled or sheet metal, having a joint at j. The
hub h, spokes 8, and inner or secondary rim ² are all cast in one piece. This
secondary rim may be made of any width desired, or may be cast with lugs or
projections on the sides, as indicated in Figure 3, thereby ensuring great strength.
In this way the joint in the outer rim may be re-inforced by placing one or more
of these lugs on the inside of the rim 2, and over the joint.
The lugs being integral with the secondary rim may readily be adapted to
cover the joint or any other part of the outer rim as will be seen.
The secondary rim when properly placed and fitted is rivetted to the outer rim
by rivets 1, 2.
This form of construction ensures a strong, simple and light pulley capable of
being run at high rates of speed without fracture.
The hub and secondary rim may be made in two parts if desired, and bolted
together before being set into the outer rim.
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:-
:-
First. A pulley comprising a jointed outer metal rim to which the hub and
spokes are connected by means of a secondary inner rim, substantially as described.
Second. The outer rim r in combination with the secondary rim r, hub h, and
spokes 8, substantially as described.
