THE WORLD'S ADVANCE 



in March is suggested by one of our 

 readers. Instead of a hook for the coat 

 and hat, a cross-arm should be nailed 

 across the board and a wooden peg 

 driven above it for the coat and hat, re- 

 spectively. The rest of the construction 

 is the same.

The Construction of a Book Rack 



The book rack illustrated in the accom- 

 panying drawings was designed by the 

 writer for filing copies of THE WORLD'S 

 ADVANCE, and it has proved very satis- 

 factory for that purpose. 



The base of the rack, b, is made of 

 hard wood and measures 20" x 8" x J4".

Two parallel grooves should be cut along 

 the centre and a brass strip mounted 

 along the track between them. One end 

 rest, a, should be secured to the base with 

 wood screws, while the other, c, slides 

 along the track by means of the brass 

 slider shown in Fig. 4. The end eleva- 

 tion of the base is shown in Fig. 2. Fig. 

 3 shows the slider before it is bent to the 

 proper shape.

A Counter for the Delivery Man 



In counting the number of bottles of 

 water or barrels or cases of other liquids 

 which are delivered, a counter such as 

 is used in billiard games will be useful. 

 The counter consists of a long brass han- 



dle, fastened to the back of the delivery 

 wagon and containing a number of 

 washers. When one delivery is made a 

 number of washers to correspond with 

 the number of units of whatever sort are 

 delivered are moved from one side of the 

 handle to the other. To prevent them 

 sliding back and becoming mixed when 

 the wagon is under way, a small wire 

 clip, inserted through a hole drilled in the 

 handle and bent at the ends as shown 

 should be added.

A Watch Case Calendar 



The owners of hunting case watches 

 will find it very convenient if the calen- 

 dar for each month is inserted in the 

 front cover of the watch. The calendars 

 should be pasted in with flour paste so 

 that they can be easily removed at the 

 end of each month.

An Enlarged Clamp 



The scope of a clamp can be increased 

 to an almost unlimited degree if the 

 lower part is cut off and the frame bolted 

 to a long wooden bar, one end of which 

 is built up with several 2x4 blocks. 

 These blocks should be securely bolted 

 to the bar.
