Complete Specification Left, 4th Mar., 1899-Accepted, 6th May, 1899
ARTHUR HATSELL OWLES, Civil Engineer, Manton House, Folkestone Road,
Dover, do hereby declare the nature of this invention to be as follows:-
This invention relates to an arrangement of any concrete mixing barrel as in
use at present or any modified shape of barrel, so that it is absolutely necessary
that the barrel must have the required number of revolutions before it is possible
to discharge into concrete trucks, also dispensing with the lifting of all materials
to deposit the charge into mixing barrel."
The arrangement consists of one two or more mixing barrels having fixed on
their trunnions, toothed wheels of small diameter; these travel on inclined racks,
so that when the barrel is at the lowest point of the incline, it is in position for
receiving the materials for one charge. The barrel after receiving its charge
is then hauled by a suitable arrangement up the inclined rack, the toothed
wheels compelling it to revolve, the length of rack or diameter of gear wheel
being so proportioned that the barrel makes the required number of revolutions,
so as to insure the proper amount of mixing. The water forming part of the
charge would not be added until the barrel has made part of its travel up the
incline, this would be added by a flexible pipe connection, or other suitable
means, through its axis, the first part of the mixing would then be with the
materials in their dry state. The mixing barrels are so arranged that only one
would be in position for charging at a time, they would then follow each other
in order so that the loads on the incline would partly balance each other only
one moving upwards at a time. This arrangement of gear and rack would
always insure the door in barrel being in the proper position for charging and
discharging.
ARTHUR HATSELL OWLES, Manton House, Folkestone Road, Dover, Kent, Civil
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:-
-
This invention relates to an arrangement, which by using any concrete mixing
barrel, as at present in use, or a modified form of barrel, it is absolutely necessary
that the barrel must have the required number of revolutions to insure proper

page_text: mixing before it is possible to empty the charge either into hopper, trucks, block-
moulds or other receptacles.
This arrangement too dispenses with lifting the materials forming the agre-
gate previous to charging the mixing barrel.
The application to concrete mixers for block-making is illustrated in Fig. 1.
B is the mixing barrel with pinions P fixed on its axis A on one, or each sude
so that when the barrel is at the bottom of the incline it is in position for
receiving the charge from hopper C. After charging it is hauled up the incline
by a suitable arrangement, such as a bridle 1), and wire rope, or by a locomotive
or motor, the toothed pinions engaging in racks R, by such means, compelling
the barrel to make a certain number of revolutions in a certain time, these
being regulated by the size, of the pinions, the length of rack and the speed of
hauling; arriving at the top of incline the barrel would then be in position for
discharging its contents into receiving hopper H.
The necessary water may either be taken in, with the other materials, or the
first few revolutions may be made dry, the water then being added through a
pierced barrel axis, either by a flexible or hydraulic jointed tube.
'
When two or more mixers are being used, they may be so arranged, that they
partly balance each other on the inclines, by one going down as the other is
going up.
In place of employing a stationary engine for hauling barrel up the incline
as above described, a motor or locomotive, mounted on the same framing as the
barrel, may be employed, the whole travelling up and down the incline and
direct to discharging position without transferring the contents into hopper H
or I may prefer to have the incline pivotted to and form part of the frame, so
that it could be raised and lowered, with the barrel on it from a suitable jib, into
the charging well; or I may dispense with the pivotted incline, the barrel then
being raised and lowered direct from or into the charging well the mixing then
being done by a suitable arrangement of pitch chain in place of rack and pinion.
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:
The application of inclined racks and pinions to concrete mixing barrels, as
described above and illustrated, so that the composing materials must have the
requisite amount of mixing before they can be discharged as concrete, and that
the lifting, lowering or conveying of materials forming the charge is done as
described during the process of mixing.
