Improvements in and rolating to Sprocket Gear and Conveying or
Elevating Apparatus.
I, JOHN MILNE, of 1, St. Mary's Place, Inverurie, in the County of Aberdeen,
North Britain, Merchant, 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 :-
-
My invention relates to sprocket gear adapted for driving machinery, and for
carrying rods, buckets, plates, platforms or the like for the purpose of conveying
or elevating goods or materials.
According to my invention I employ sprocket or chain wheels of suitable
construction such as that hereinafter described secured to the driving and driven
shafts of the machinery, and a simple or common chain the links of which are
of uniform length, or alternately short and long, the teeth of the sprocket wheels
engaging alternate links of the chain.
When adapting my sprocket gear for carrying rods, buckets, plates, platforms
or the like for conveying or elevating goods or materials I employ two sets of
pulleys and chains, the rods, buckets, plates or platforms being carried by the
alternate chain-links which do not engage the teeth of the sprocket wheels.
In the accompanying drawing,
Figure 1 is an elevation of a sprocket wheel driven by a simple or common
chain according to my invention; and
Figure 2 is a plan of part of the chains, and plates or platforms forming my
improved conveyor or elevator.
a is one of the sprocket wheels; these wheels may be of any construction
suitable for the purpose of gearing with the chain. For example the wheel is
cast in one piece and is made with recesses band between the recesses with the
toothed partions c. d is the chain which, as is clearly shewn in the drawing,
is of ordinary construction. The alternate links of this chain engage the teeth c
of the sprocket wheels, and rest upon the peripheral unrecessed portions b¹ of
the wheel whilst the other links pass into the spaces constructed to receive them.
d', d, d' are the plates, bars, or the like having their ends or pivots inserted
in the alternate chain links which do not engage with the sprocket teeth e, the
recesses b in the chain wheels receiving them when the chain engages the toothed
discs.
By my invention I provide a very cheap and efficient means for driving
machinery and conveying goods or materials.
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. The combination with sprocket wheels of suitable construction, of simple or
common chains for the purpose of driving machinery, substantially as herein-
before described and illustrated in the accompanying drawing.
2. The combination with sprocket wheels and simple or common chains, of

elevating goods and materials, substantially as herein before described and illus-
trated in the accompanying drawing.
