DISTRIBUTING MECHANISM FOR PRESSURE
CONCRETE TRANSPORTATION SYSTEMS
Charles I. Longenecker, Wauwatosa, Wis., as
signor to Chain Belt Company, Milwaukee,
Wis., a corporation of Wisconsin
Application May_18, 1934, ‘Serial No. 726,392
8 Claims. (01. 193-4)
This invention relates to pressure pipe line
transportation systems for plastic concrete mix
tures and the like, and more particularly to ap
paratus for facilitating the distribution of the
CA mixture as it leaves the pipe line, and has for one
of its objects to provide mechanism of this char
acter which will be simple in construction, com
paratively inexpensive to! manufacture, and more
10
efficient in use than those which have been here
tofore proposed.
There has been recently developed a system of
concrete distribution wherein the plastic mix
tures of all commonly used consistencies and
15
V proportions of ingredients are pumped by means
' of mechanical pumps through closed conduits of
from 5" to '7" in diameter. The pumps. are ca
pable of producing pressures up to 500 pounds per
shown in Figure 4 certain of the parts being
omitted for the sake of clearness;
Figure 7 is a side elevational view similar to
Figure 2, of a somewhat modi?ed form of the in
vention positioned to receive plastic concrete mix- 5
ture from an intermediate port in the pipe line;
and
Figure 8 is a sectional elevational View taken
approximately on the plane indicated by the line
8—8 of Figure '7.
10
Referring more particularly to Figures 1 to 6
inclusive there is illustrated a pipe section It!
forming a portion of a conduit leading from any
suitable pressure inducing means capable of forc
ing the concrete mixture therethrough, the open 15‘
end ll of which forms a discharge port from
which the mixture issues. These pipe sections are
square inch or more, and the mixtures may be _ commonly supported in any suitable manner
some distance over the ground or the form into
or more. The distribution of the concrete mix
which the mixture is to be deposited, such sup- 20
“ forced over horizontal distances up to 1,000 feet
so
tures as they leave the pipe line presents certain
problems and heretofore has involved consider
able hand labor, and it is the primary object of
the present invention to provide a simple and effi
cient apparatus for facilitating such distribution
of the mixtures as they leave the line.
‘
With the above and other objects in view which
will appear as the description proceeds, the in
vention consists in the novel details of construc
30 tion and combinations of parts more fully here
40
structure l2 which in this form of the inven
tion is shown as comp-rising‘a longitudinally ex
tending tubular member or pipe I3 provided with 25
a pair of transversely extending spaced mem
bers l4 and I5, each of which comprises a pair
of spaced plates: l6 and I1 which may be welded
or otherwise rigidly secured to the longitudinal
member I3.

The longitudinal member l3 of the trolley
receive the upwardly extending members 53 to
structure extends somewhat beyond the trans
verse member I5 and adjacent its extreme end
is provided with a hook 28 swivelly connected
thereto. A trough or chute 30 having a hopper
3| at one end is adapted to be hung upon the
which is attached a horizontal skid member 54
adapted to rest upon the ground or other surface,
as will be clear from the drawings. Brace mem
bers 55 are provided between the chute and the
lower ends of members 52, and the upwardly ex
tending members 53 are maintained in adjusted
relation to the members 52 by means of suitable
hook 28 by means of an eye 32 carried by a trans
verse bracing bar 33 positioned within the hop
per 3| and welded or otherwise rigidly secured
cured to the chute 30, and suitable angularly
disposed brace members 3'! extend from the free
as will be readily understood.
Figures 1 and 2. A pair of substantially hori
zontal arms 35 have their forward ends 35 se
15 ends 38 of arms 35 to the hopper end of the said
chute. ' A counter-weight 39 is attached to the
ends 33 of arms 35, said counter-weight being
of appropriate size to counter-balance the chute
30 so as to normally maintain it in substan
20 tially the position shown in Figures 1 and 2.
In use the trolley structure I2 is placed upon
the pipe section [0 and the chute 3B is suspend
ed therefrom by engagement of the eye 32 with
the swivelled hook 28. The concrete mixture is
25 suing from the discharge port ll of pipe IE will
be received within the hopper 3!} and due to the
inclination of the chute 38 will flow down the
same to the lower end from which it will be dis
charged. Owing to the swivel connection be
30 tween the chute and the trolley structure, the
said chute may be swung horizontally to dis
charge the mixture over a comparatively wide
area.
If desired a deflector member 40 may be piv
35 otally attached to a pair of ears 41 carried by
brace member 25 of the trolley structure so that
it may be positioned as shown in Figure 2 to de
?eet the mixture downwardly and into the hopper
3|. If the de?ector 40 is not necessary it may
be swung in a counter-clockwise direction about
its pivot to an inoperative position above the
pipe section It), as will be readily understood.
If it be desired to discharge concrete directly
from the pipe line Without using the distributing
45 chute the trolley structure l2 and the chute may
be moved toward the left as viewed in Figures
1 and 2 to remove the chute from below the dis
charge port II, the pipe section Ill serving as a
track for the trolley structure.
In the modi?ed form of the invention shown in
Figures '7 and 8 the trolley structure [2 is quite
similar to that previously described except that
the horizontal member l3‘ takes an inverted
channel form and is downwardly inclined toward
55 the right as viewed in Figure 7. At the extreme
right hand end of the member It’ there is secured
a ball or nubbin 45 which is adapted to be readily
removably received in a suitable recess 46 pro
vided in a block 41 welded or otherwise rigidly
secured to the under surface of the chute 30.
There is thus provided a somewhat different form
of universal connection between the chute and the
trolley structure which permits of swinging move
ments of the chute in all directions as will be
65
bolts 56, passing through cooperating spaced holes
5'! formed in the members 52 and 53. It is pos- 10
sible by sliding the members 53 in or out of the
members 52 to vary the height of the skid struc
ture and therefore the inclination of the trough 30,
10 to the side walls thereof, as will be clear from
readily understood.
In lieu of the counter-weight illustrated in the
other form of the invention, there is shown in
Figures 7 and 8 a skid construction for the lower
end of the chute 3.0 which comprises a pair of
plate members 50 which may be detachably se
cured to the sides of the chute 3|] and which have
welded or otherwise rigidly secured to them the
laterally extending tubular members 5|, to which
are rigidly secured the downwardly extending
tubular members 52. Said members 52 slidably
-
The invention is illustrated in Figures '7 and 8 15
as being positioned to receive the mixture from
a port 68 located between the ends of pipe section
H! but it is obvious that it is also adapted to re
ceive concrete from the end discharge port II,
and also that the form of the invention illus- 20
trated in Figures 1 and 2 may be employed to re
ceive the mixture from an intermediate port 60 if
desired. It is also obvious that the skid structure,
and counterweight structure illustrated, are in
terchangeable in the different forms of the in- 25
vention.
It will be observed that the supporting connec
tion between the trolley and the chute, permitting
adjustment of the latter, is located sufficiently to
one side of (a direction which I herein term for- 30
ward) the supporting connections between the
trolley and the pipe to permit the chute to be
adjusted along with the trolley relative to the dis
charge port of the conduit so as to receive material
therefrom without any interference from the 35
parts of. the trolley.
It is obvious that those skilled in the art may
vary the details of'construction as well as the
precise arrangement of parts without departing
from the spirit of the invention and therefore it 40
is not wished to be limited to the above disclosure
except as may be required by the claims. 7
