The Winget Machine, manufactured in Columbus, Ohio, is illustrated 
in figures F41 and 142. One ideal which all block machine makers strive 
to attain, is the elasticity in size and shape of their blocks. Most block 
machines attain this ideal to a greater or less degree. Another require- 
inent is to keep strength and reduce material, which is accomplished by 
making the block hollow—this also makes walls which keep more equable 
temperatures within the structure, and which aid in preventing. moisture 
reaching the interior surface of the walls.

The Winget machine is so adjusted that the sides of a block can be 
faced with a richer mortar half or three-quarters of an inch thick. This 
gives a neater, smoother face to the stone and makes it less pervious to 
water. If desired, this outer shell can be colored, giving a very fair imi- 
tation of natural stone without being expensive in coloring matter. It 
is said that four men using this machine can produce 150 blocks per ten 
hours. The usual size is 9 inches by to inches by 32 inches.. The Winget 
machine makes blocks having very sharp, neat, well defined corners, which 
is an essential to neat construction. The Winget Concrete Machine Com- 
pany claim that blocks can be made with their machine and laid for about 
thirty cents apiece. Figure 143 shows the various shapes and patterns 
of blocks made in a Winget machine. 
The Normandin Machine.—The Normandin machine also seems to 
be a very good machine. Figure 144 illustrates this machine. Similar 
to nearly all of the other block machines it has adjustable or exchangeable 
sides so that face designs can be substituted for plain faces. 
The Palmer Machine. —The Palmer machine is one of the first de- 
signed of this class of machines. A great many neat houses have been
