page_text: I, OTTO WILHELM GANHE, Engineer, Rhine and Lahn Manufactory, Oberlahustein,
Germany, do hereby declare the nature of the said 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 that type of elevators, in which tubs, trucks, vessels,
buckets, or the like are either raised, or lowered by a system of endless chains running
continuously and supported and guided by winding drums.
According to this Invention, construct apparatus of the type above specified in
such a manner that the tubs, trucks, or the like are automatically engaged with the
continuously running chains, then raised and then automatically disengaged from the
chains.
An example of means according to this Invention for effecting the mode of
elevating just described is illustrated in the annexed sheet of Drawings, in which
Figure 1 is a side elevation of the apparatus.
Figures 2 and 3 are side elevation and front view respectively of a portion of the
chain and bucket.
;
Referring to the Figures of the Drawings a designates the endless link chains
fare supporting or winding barrels for the chains e are pins connecting the links
together and h represent the buckets provided with lifting or elevating handles, or
straps c. 6 designate studs secured either to the links between the rivets e, or they
may form a projecting portion of the rivets e themselves as shown in the lower
portion of the chains in Figure 3 marked e e. The studs constitute the means by
which the buckets are engaged with the chains and elevated by them. d designates
digramatically a platform from and onto which the buckets are raised and deposited.
It will be seen that the two endless link chains a run parallel to each other, but
are not stayed to each other. They are each provided at certain distances with the
studs which face each other. The tubs, or vessels are rather narrower than the
intermediate spaces between the two studs b but the straps c are bent sufficiently
outwards to engage with the studs b. If a tub or vessel is pushed onto the lower
of two platforms d which is provided with side guides and a ledge far enough in
Price 6d1

page_text: between the two chains when in motion, it is caught in its straps c by a pair of the
studs 6 carried upwards lifted over the top barrel fand set down automatically on a
second platform. The studs 7 then leave the lugs, or straps c of the bucket, or
vessel. This is all performed without it being necessary to stop the motion of the
apparatus. The bucket must then be removed before the next ascending pair of
studs 6 reaches the top. For this purpose the platform d may be given such an
inclination that when the bucket is let go, it slides of itself beyond the reach of
the studs.
If the bucket happens to be of such a length that it would knock against the
axles of the drum when lifted over, two separate studs can be used with one drum
each in between which the buckets are then made to pass. The axles are driven in
such a case by separate wheels.
The studs may either be fastened specially onto the chain links as shown, or the
link studs e may be provided with stud like projections as shown.
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 :-
First. In apparatus of the type herein described the construction and arrangement
of parts by which the buckets, tubs, vessels, or the like are automatically engaged,
elevated and then automatically released, as, or substantially as set forth.
Second. The studs b or e, bucket h having straps c chain a barrels, or wheels fand
platforms d, combined, constructed and operating as set forth with reference to the
Drawings.
