IMPROVEMENTS IN "CENTRIFUGAL REELS APPLICABLE TO FLOUR BOLTING MACHINES
Year: 1884

page_text: I WILLIAM HENRY DICKEY of Jackson in the County of Jackson and State
of Michigan, one of the United States of America, Manufacturer, do hereby
declare the nature of my invention for IMPROVEMENTS IN "CENTRIFUGAL REELS
APPLICABLE TO FLOUR BOLTING MACHINES" 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 centrifugal reels, and consists essentially in the
construction and combination of elements hereinafter fully and in detail set
forth and then specifically pointed out in the claims.
To enable one skilled in the art to which this invention appertains to make and
use the same reference should be had to the accompanying drawings, in which,
Fig. 1, is a central vertical longitudinal section of so much of a centrifugal reel
as is necessary to illustrate my invention.
Fig. 2, is a detached view, enlarged.
Fig. 3, is a detached view, also enlarged showing the sleeve bearing.
Figs. 4 and 5, are like views, showing modifications.
Fig. 6, is a plan or top view of one end of the reel-trunnion, the gear having
been removed, and showing the groove d', as being cut entirely through the
trunnion.
Referring particularly to Figs. 1, 2 and 3, A, is the beater shaft, its ends a, a,
being of reduced diameter, forming shoulders, for the purpose presently explained.
B, B, are spiders, and b, b, are beaters mounted upon and carried by the beater
shaft.
C, C, are respectively the spokes or arms and flange of the rec!-head at the
discharging end of the machine.
The spokes C, C, project radially from a hollow trunnion or tubular support D,;
which extends through the casing, and is mounted in a bearing F, which parts
may be of any approved or usual construction.
F, is a chamber or offal box having a circular opening in its inner wall, the
opening being concentric to the tubular support D, D. c, is a circular flange
formed on the reel-head, and also concentric to the tubular support D, so as to fit.
closely the opening in the offal-box.
The reel-head at the opposite end of the bolt consists of an outer rim H, hollow
trunnion or tubular support D, which are connected by means of curved arms h, h,
like that at the discharging end of the reel.
As the construction of the tubular supports and the bearings at each end of the
reel are all substantially alike, I will describe one only.
Referring particularly to Figs. 2 and 3, the bearing is constructed with a central,
spherical portion E, having two projecting cylindrical portions E', E2, and is
provided with a longitudinal opening or seat to receive the end of the beater-shaft."

page_text: The tubular support D, is enlarged at its outer end and constructed with a
concave shoulder, substantially as indicated at d, to receive and support the
opposing adjacent face of the sleeve-bearing.
This bearing is provided at it's greatest diameter with a projecting lug e, which
enters and is seated in a groove d', in the inner face of the tubular support.
In order to retain the sleeve-bearing in proper position, and also to prevent
longitudinal movement of the beater-shaft, I employ stops rigidly attached to the
beater-shaft at its ends which project beyond the sleeve-bearings.
By preference the stop at the tail end or discharging end consists of a spur-
pinion G, which meshes with the spur-gear G', having attached thereto a spur-
pinion g, meshing with a spur-gear gl, which is rigidly secured upon the tubular
support D, so that when the beater shaft is rotated this train of gearing rotates the
reel at a reduced speed.
The stop at the opposite end or receiving end of the bolt may consist of a simple
collar I, keyed or otherwise rigidly secured to the beater-shaft.
In Fig. 4, I have shown a construction in which the beater-shaft is of uniform
diameter from end to end, the parts being otherwise constructed substantially as
indicated in Fig. 1, except that the stop, which in this instance is a pinion G, does
not engage with the outer end of the tubular support, but is in close contact only
with the outer end of the cylindrical part E, of the sleeve-bearing.
In this figure the beater shaft is shown as being of uniform diameter throughout.
In Fig. 5, the opening in the tubular support is of uniform diameter from end to
end, and hence the stops on the shaft should be arranged to engage with not only
with the outer ends of the sleeve-bearings, but also with the outer ends of the
tubular support at both ends of the reel, in order to prevent longitudinal movement
of either the beater-shaft or the sleeve-bearings. In Figs. 4 and 5, the upper side
of the tubular support is slotted, as at d³, to receive the pin or lug e, which
prevents the sleeve-bearing from rotating.
In Fig. 6, I have shown the pin e, as projecting entirely through the slot which.
is formed in the trunnion and extends to one end thereof, as indicated at ', while
in Figs. 1 and 2, the pin does not project entirely through the trunnion, but is
seated in a longitudinal groove formed in the inner surface of the trunnion; but
so far as performing its function of preventing the sleeve-bearing from rotating is
concerned, the pin operates in substantially the same manner whether it be seated
in the comparatively shallow groove or in the slot which is cut entirely through
the trunnion.

Among the advantages which are incident to this invention are the following
In consequence of the tubular support, the sleeve-bearing, and the beater-shaft
being mounted upon or in a single bearing or boxing at each end of the reel, there
is much less liability of any disturbance in the alignment of these bearings than
there would be if the bearings for the ends of the shaft were separate from the
bearings for the tubular supports of the reel, and this is true even though the shaft
bearing and the tubular-support bearing were both cast in the same piece with the
shaft-bearing at some distance farther from the end of the machine than the
tubular support and trunnion bearing, as is the case for instance in the reel shown
in U. S. Patent No. 266,781, W. B. Dell, Oct. 31, 1882, upon which this invention
is intended as an improvement. By reference to that Dell patent it will be seen
that there are separate and independent supports for the beater shaft and the
tubular reel-supports at both ends of the machine, these supports being at such
distance apart as to permit the introduction of mechanism between them, whereas
in my invention the boxing which supports the beater-shaft and the tubular réel-
support is one and the same, and is arranged between the spur-pinion G, and the
collar I.
Another advantage is the facility with which long sleeve bearings for the beater
shaft may be employed, it being apparent that they may be made to project to any
desired length inside of the tubular supports D.

page_text: Again, by reference to Fig. 5, it will be readily understood that the spur-
pinion G, and the stop at the other end of the machine serve not only to confine
the sleeve-bearings in position relatively to the beater-shaft, but also prevent
longitudinal movement of both the bearings and the shaft relative to the tubular
supports.
In all the constructions shown the sleeve-bearings are placed loosely within the
tubular supports, and are held in position against lateral play only by the stops,
which are affixed to the beater-shaft and engage with the outer ends of said sleeve-
bearings.
Having now particularly described and ascertained the naturo of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. In a four-bolt, the combination of a reel having a head provided with a
projecting tubular support, a beater-shaft within the tubular support, a sleeve-
bearing mounted loosely in said tubular support, a boxing on the frame supporting
both the sleeve-bearing and the tubular support, and a stop attached to the beater-
shaft to prevent it from moving longitudinally in the sleeve-bearing, substantially
as set forth.
2. In a flour-bolt, the combination with a reel having a head provided with a
projecting tubular support, a beater-shaft within the tubular support, a sleeve-
bearing surrounding the beater-shaft, and having a globe-shaped expanded portion,
a boxing on the frame supporting both the sleeve-bearing and the tubular-support,
and a stop attached to the beater-shaft to prevent it from moving longitudinally in
the sleeve-bearing, substantially as described.
3. In a flour-bolt, the combination of a reel having a head provided with a
projecting tubular support, a beater-shaft within the tubular support, a sleeve-
bearing surrounding the beater-shaft and mounted loosely in said tubular support,

projecting tubular support, a beater-shaft arranged within the tubular shaft, a
sleeve bearing having a cylindrical portion of less diameter than the opening in the
tubular support and arranged therein, a lug d, projecting from the sleeve bearing,
and a seat in the inner wall of the tubular support to receive the lug, as shown
and described.
6. In a flour-bolt, the combination of the reel having two heads, each provided
with a projecting tubular support, a beater-shaft within the tubular supports, a
beater-shaft within the sleeve-bearings, and stops rigidly affixed to the shaft and
