COMPLETE SPECIFICATION.
An Improved Construction of Elevator, particularly adapted for
Carrying Large Flanged Bobbins or the like from One Floor of
a Waste or Shoddy Mill to another.
I, ROBERT BIRTWISTLE, Trading as S. S. Stott and Company, of Laneside
Foundry, Haslingden, in the County of Lancaster, Engineers and Ironfounders,
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 an improved construction of elevator which is particu-
larly adapted for carrying large flanged bobbins or the like from one floor of a
waste or shoddy mill to another, for example, from the carding room to the spin-
ning room and vice versa.
These large bobbins have pivots, and are usually about three feet six inches
long with about eight inch flanges, and are consequently unwieldy articles to
handle especially when full, the material on the bobbins being of a delicate
nature and easily damaged.
The chief object of my invention is to lighten the labour and facilitate the
handling of these large bobbins.
In the accompanying three sheets of drawings-
Figure 1 is a side elevation, Figure 2 a front elevation, and Figure 3 a detail
view of an elevator constructed according to my invention.
In these views,-1 denotes the frame of the elevator, the pair of travelling
chains, 3 the chain, wheels of which the upper pair are driven by the spur wheel 4
on the shaft 5 of the upper chain wheels and a pinion 6 and belt pulleys 7 on
a driving shaft 8.
On the chains 2 at convenient distances apart are fixed pairs of carriers 9
each of which is adapted to receive the pivots of a large flanged bobbin 10 in
whichever direction the chains may be travelling.
The full bobbins 10 are placed on a feed box or table 11 on the ground or
lower floor, the table being inelined inwardly so that the bobbins will always run
towards the elevator from the outside end. The table 11 has two openings cut in
it to permit the passage of the chains 2 and pairs of carriers 9, and as each pair
of carriers successively passes through these openings it takes up by the pivots
the full bobbin 10 resting on the inward end of the table 11 and carries it
upward and over the top of the elevator until it reaches the outwardly inclined
delivery table 12 on the upper floor on to which the bobbin rolls.
carriers 9 move downwards a catch 13 fixed on one of the chains in advance of the
carriers comes in contact with an arm 14 fixed on a shaft 15 which is free to be
turned in bearings and is connected by a rod 16 to an arm 17 fixed on studs 18,
one on each side of the elevator, from which is suspended a segmental plate 19
connected at each end to the studs 18 on which is also fixed an arm 20 connected
The other end of the
by a link 21 to one end of a link 22 fixed on a shaft 23.
As the

page_text: lever 22 and an arm (not shown) fixed on the opposite end of the shaft 23
are connected to a pair of rods or draw bolts 24 which normally hold the end
bobbin 10 on the feed table 25 in the position shown in Fig. 3. This feed table 25
is for the empty bobbins and is inclined inwardly as shown, so that the bobbins
always tend to roll down towards the elevator, but to prevent the flanges of the
empty bobbins from becoming jammed or interlocked I employ a series of inclined
levers 26 heavier at one end than the other and pivoted to the sides of the table;
these levers are only free to move a slight distance up or down, their movements
being limited by stops, but when a bobbin is resting as shown in Fig. 3, on the
front ends of one pair of levers 26 it raises the heavier ends of the said pair of
levers sufficiently to catch the pivots of the next bobbin 10 and prevent it from
rolling down the incline until the catch 13 acting on the arm 14 through its
connections draws down the arm 17 on the studs 18 and so tilts the segmental
plate 19 and rolls the empty bobbin therein on to the pair of carriers 9 which
follow the catch 13.
Simultaneously the connections from the studs 18 draw down the bolts 24 and
allow the next empty bobbin 10 to roll forward off its pair of levers 26 into the
empty segmental plate 19, and as the said pair of levers 26 are relieved their
weighted ends descend and release the next empty bobbin 10 which rolls forward
against the draw bolts 24 which by this time owing to the weight 31 on the
shaft 15 will have regained their normal position in common with the other con-
nections after the catch 13 has passed the arm 14.
The empty bobbin 10 is carried down by the pair of carriers 9 until it reaches
the delivery table 27 which takes off the bobbin 10 and the table being inclined
away from the elevator the bobbin rolls clear as shown in Fig. 1.
It will be obvious that the elevator may carry up empty and bring down full
bobbins, and further that it may be employed without an automatic feed for the
empty bobbins if preferred.
The shaft 28 of the lower pair of chain wheels 3 is journalled in slide blocks 29
each of which is adjustable by means of screws 30 in order to take up any slack
in the chains 2.
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. An elevator adapted for carrying large flanged bobbins or the like with pivots
from one floor to another of a shoddy or waste mill substantially as herein set
forth.
2. In combination, the travelling elevator chains, pairs of carriers 9 attached
thereto and suitable feed and delivery tables for the flanged bobbins with pivots
substantially as herein set forth.
3. The combination with the elevator set forth in Claim 2, of the arrangements
of parts constituting an automatic feed for the empty or full bobbins substan-
tially as herein set forth.
