Self-Measuring Wheelbarrow for 

 Concrete Aggregates 



A SELF- MEASURING wheelbarrow 

 designed to promote convenience, 

 rapidity and accuracy in handling con- 

 crete aggregate, is shown in the accom- 

 panying sketch. It consists of an ordinary

Measuring box on a wheelbarrow for ob- 

 taining the proper amounts of concrete 



steel body wheelbarrow pan with a trans- 

 verse wood gage of the same shape as the 

 inside of the pan. This gage is moved 

 up and down in the pan, according to the 

 amount of concrete to be carried, the 

 latter being measured between the gage- 

 board and the rear end of the pan. The 

 gage-board may be set at any desired 

 position by means of a transverse bar 

 across the top of the pan. The bar is held 

 in place by two pins inserted through any 

 one of a series of small holes along the 

 sides of the pan at the top. The gage- 

 board is held against the transverse bar 

 by a vertical wooden piece nailed to a web 

 fitted to the gage-board at right angles 

 to it at the open end. When the concrete 

 is to be dumped, the gage-board is re- 

 moved. 



Applying Grease to Working Gloves 

 to Make Them Wear 



A FRIEND of mine who does heavy 

 work of various kinds which requires 

 gloves, and heavy leather gloves at that, 

 advises me that gloves can be made to 

 wear almost like iron by applying axle 

 grease sparingly and being very careful 

 not to get it on the cloth stitching, as the 

 axle grease may disintegrate it- somewhat.

Making a Photographic Timer out 

 of an Ordinary Watch 



A SIMPLE adaptation of an ordinary 

 watch to use as a timer of value in 

 long photographic exposures by photo- 

 engravers and printers, or for use in 

 timing action of developer, can be made 

 by painting a narrow line on the under 

 side of the edge of the watch crystal. 

 Then, by revolving the crystal till the 

 mark coincides with the minute hand, it is 

 easy to register the exact time that ex- 

 posure began. — George Parke. 



Joining the Ends of Carpet Rags 

 Without Sewing 



AN old backwoodsman used this 

 . method of joining carpet rags end to 

 end, without sewing the strips together. 

 He mounted a strong knife blade, pre- 

 viously shaped like a crochet needle, as 

 shown in Fig. 1, on the bench he used for a 

 seat. The point and upper edges of the 

 knife were sharpened as shown in Fig. 2. 

 Taking the ends of two strips, he pressed 

 them down over the blade. Fig. 3, until 

 they were as shown in Fig. 4. One end 

 was looped under the eye of the needle, 

 Fig. 5, and while holding the ends A and 



Knife blade arrangement for fastening the 

 ends of carpet rags without stitching 



B, Fig. 6, they were drawn upward. The 

 resultant knot, Fig. 7, can be shaped as in 

 Fig. 8 and drawn tightly as in Pig. 9. 

 Other pieces are attached in the same 

 manner to make a continuous line for the 

 weaving. — James M. Kane.
