Improvements in Conveyors.
I, JAMES MAPES DODGE of Clapier Street and McKean Avenue German Town
Philadelphia. County of Philadelphia, State of Pennsylvania, U.S.A. Mechanical
Engineer 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:-
The object of my invention is to utilize rods in the construction of conveyors,.
and this object I attain.by so connecting the rods together and to the "flights
that they will have free movement, the parts being cheaply manufactured and
readily put together.
In the accompanying drawing :-
:―
Figure 1 is a plan view, partly-in section, of a portion of a conveyor illustrating-
my invention;
Figure 2 is a view in elevation, partly in section;
Figure 3 is a perspective view of one of the flights with the rods attached ;
Figures 4 and 5 are views of a modification of my invention; and
Figures 6 and 7 are views shewing other modifications of my invention.
A is the "flight" or pocket section, having a vertical cylindrical pocket B and a
horizontal cylindrical pocket C, each pocket being preferably open at each end as.
shewn. A horizontal slot is cut in the shell of the pocket B, and a vertical
slot c is cut into the shell of the pocket C.
с
Adapted to the pocket B is a cylindrical head D and a rod E passes through the-
slot band is tapped into the head D or otherwise fastened to the said head. The
slot is of such a length as to allow the rod sufficient lateral movement.
The opposite end of the rod is screwed or otherwise fastened to a cylindrical head F
adapted to the horizontal pocket C, the rod passing through the slot c in the casing
which is of sufficient length to allow the rod the vertical movement required.
As-shewn in Figures 1 and 2 the "flight" A is cast with the pockets, but it will
be understood that the pocket section may have a flange to which the "flights" are."
secured as shewn by dotted lines in Figure 1. In this figure I have shewn the.
pockets B and C adjoining, so that the two heads come in close proximity to each
other. In this instance, the flights are so arranged that the horizontal head can be.
slipped in from the side, and the vertical head can be slipped in position from the.
top, and when the heads are in position they are secured to the rods.
In Figures 4 and 5, I have shewn a disc "flight" in which case I preferably.
form the pockets sufficiently far apart so that the " flights" will not interfere with
the mounting of the heads in the pockets.
66
In Figure 6 I have shewn the pockets formed in independent pieces secured to a.
flight" by bolts, rivets or other fastenings. Thus, while the rods are free to.
accommodate themselves to the trough or the sprocket wheels around which the.
conveyor must pass, the "flights" are always held in proper position to convey the.
material in the troughs.
In some instances, one of the pockets may be a closed pocket as shewn in.
Figure 7, and the head adapted to the said pocket may be passed through from the.
opposite pocket as clearly shewn in said figure, the opposite pocket having both the
transverse and vertical opening, one for the transverse head and the other for-
the vertical head.
It will be understood that the "flights" may be of different shapes and may
be in the form of buckets or carriers, without departing from the nature of my-
invention.

page_text: 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. The combination in a conveyor, of a series of rods having heads at each
end arranged at right angles to each other, with connecting sections having
pockets also at right angles to each other and adapted to receive the heads of
adjoining rods, substantially as hereinbefore described.
Second. The combination in a conveyor, of a series of rods having heads
arranged at right angles to each other, with a "flight" section having pockets also
arranged at right angles to each other and adapted to receive the heads of
adjoining rods, the said "flight" section being slotted for the free movement of the
bolts, substantially as herein before described.
Third. The combination of the "flight" section having pockets arranged at
right angles to each other, cylindrical heads adapted to the said pockets, slots in
the "flight" section communicating with the pockets, screw threaded openings in
the heads, and rods adapted to pass through the slots and into the screw threaded
openings of the heads, substantially as herein before described.
Fourth. The combination in a conveyor, of the "flight" section, a vertical
pocket and a horizontal pocket therein, the casing of the vertical pocket having a
horizontal slot, and the casing of the horizontal pocket having a vertical slot, heads
adapted to the said pockets, and rods adapted to the said slots and secured to the
said heads, substantially as hereinbefore described.
