Improvements in the Construotion of the Links and their Parts for
Conveyors and Elevators.
I, CHARLES HUNT of Windsor Street Gas Works, Birmingham in the County
of Warwick, Civil Engineer, do hereby declare the nature of my said 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 has for its object improvements in the construction of the links
and their parts for conveyors and elevators by which simplicity in construction
and manufacture is obtained with reduced friction and increased endurance.
For the purpose of making my invention quite clear I have appended hereunto
a sheet of drawings upon which I have illustrated an example of the same, but it
must be understood that I do not confine myself to the particular designs & con-
figurations shown as they are varied to suit the particular work to be accomplished,
and it must likewise be understood that I do not claim a liner or roller working
barely upon a cross connecting pin for coupling the links together.
The figures on the drawings are as follows:-
Figure 1 is a plan showing two links A and A¹ of my chain coupled together by
the cross pin P.
Figure 2 is a side elevation of the links A, A shewn coupled together as seen at
Figure 1.
Figure 3 is a cross section through the link junction and pin P on the line 1, 2.
I have said that the links may be made of any desired configuration to suit the
conveyors or elevators buckets, but they consist in all cases of two seperate side
pieces A and A' which form each link in conjunction with a hollow roller R and
pin P. The links are made right and left handed so that the spigots or projec-
tions a, a face each other, and upon which the roller R fits loosely, as shewn
clearly in section at Figure 3. The plan Figure 2 shows the roller R at the
junction of the two links but the roller at the right hand is omitted for the purpose
of making plain the projections or spigots a', a which constitute a very important
feature of my present invention. It will be seen that the projections a³ are oast
or forged upon the sides of the links A and A' and that the wear caused by the
roller R turning is upon these spigots, projections or spindles a³ and not upon the
pin P as this merely serves as a conneoting medium for the links and does not
carry the strain due to the conveying or elevating work of the chain. The links
shown upon the drawing have a collar a at the spigot end and similar collars a at
the wider ends to strengthen the bosses a' through the hole H of which the pin P
passes to fasten the links together.
The pin P may be fastened by lock nuts or a cotter C as desired.
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 improvements in the construction of the links and their parts for conveyors
and elevators consisting of the right and left side pieces A and A' with their solid

page_text: substantially as and for the purpose herein set forth and as shewn upon the
accompanying sheet of drawings by Figures 1 to 3 inclusive.
Dated: this 24th day of December 1896.
