With such adjustments the upper part of
side 11 may be inclined inwardly more or
less to change the bevel on the sides of
blocks formed in the molds to meet the re-
5 quirements of blocks for building cylindri-
cal structures of different diameters.
The ends of the end pieces 6 may have
adjustable sections 28 for the purpose of
adjusting the side member 12. Bolts 29 are
10 countersunk in the detachable sections for
the purpose of adjusting the sections to
make provision for adjusting the side 12.
In order to prevent any sagging of the
swinging ends of the end pieces 6, lugs 30
15 are formed on the lower parts of the ends
of the side 12 to support the end pieces 6
in their normal positions.
The pallet is curved as the case may be.
If the structure to be built has a large curva-
20 ture or circumference, the curve will be
greater on the concave side of the pallet.
Two of the edges of the blocks require
grooves therein and the other two edges re-
quire ribs to conform to the grooves in the
25 adjacent block. The ribs are formed on the
blocks by making grooves 31 in sides of the
molding members and the grooves in the
blocks are formed by ribs 32 formed on the
sides of the molding members. Various
30 changes may be made in the sizes, propor-
tions, and structure of the various parts
without departing from my invention and
the several parts may be reversed without
changing the manner of operating.. In or-
35 der to hold the levers 17 in line so that they
will not strike the end pieces 6, studs 33 are
inserted in side 12 to prevent the ends of the
levers from moving out of place.
What I claim, is,-
40 1. A mold for forming blocks comprising
a frame, a side member hinged thereto,
levers fulcrumed on said side member,
brackets attached to the other side of said
frame, a side member adjustably mounted on
45 said brackets, a pallet placed on said frame,
and end members hingedly connected to said
brackets and bearing against said side mem-
bers, and held in place by said levers.
2. A mold for forming blocks of plastic
50 material comprising a frame, a side member
hinged to one side of said frame, brackets
mounted on the other side of said frame, a
side member adjustably mounted on said
brackets, means cooperating with said
55 brackets for varying the inclination of the
last mentioned side member, and end mem-
bers hingedly connected to said brackets andbearing against the ends of said side mem-
bers.
3. A mold. for forming blocks of plastic 60
material comprising a frame, a pallet
mounted on said frame, a. side member
hinged to one side of said frame, brackets
attached to the other side of said frame, a
side member pivotally connected to said 65
brackets, end members hingedly connected
to said brackets and bearing against the ends
of said side members, and clamping levers
fulcrumed on the first mentioned side mem-
ber for clamping said end members against 70
the end of said side members.
4. A mold for forming blocks of plastic
material comprising a frame, a pallet
mounted on said frame, a side member
hinged to one side of said frame, brackets 75
mounted on the other side of said frame, a
side member pivotally connected to said
brackets, means for inclining the last men-
tioned side member consisting of reversible
gages having sides of different thicknesses 80
mounted on said brackets and bearing against
said side-member connected to said brackets,
and end members hingedly connected to said
brackets: and bearing against the ends of
said side members. 85
5. A mold for forming blocks of plastic
material comprising a frame, a pallet
mounted on said frame, a side member
hinged to one side of said frame, brackets
mounted on the other side of said frame, a 90
side member pivotally connected to said
brackets and means coperating with said
brackets to hold said brackets at different
inclines, cams for supporting said inclined
side- member at different adjustments, and 95
end members hinged to said brackets and
bearing against said side members.
6. A mold for forming blocks of plastic
material comprising a frame, a pallet on said
frame, a side member hinged to one side of 100
said frame and having lugs projecting from
the ends thereof, brackets mounted on the
ether side of said frame, a side member
pivotally connected to said brackets, gages
mounted on said brackets and coperating 105
with said brackets for holding the side mem-
ber connected to said brackets at different
inclines, and end members hinged to said
brackets and bearing against the ends of
said side members and supported on said 110
lugs.
In testimony whereof, I set my hand, this
15th day of November, 1916.
