Enlarging a Runabout's Capacity 



THE torpedo extension with which 

 most runabouts are built is often 

 inadequate for carrying packages or bun- 

 dles of more than ordinary size. With 

 some extra lumber, the 

 capacity of a small au- 

 tomobile may be con- 

 siderably increased, as 

 shown in the sketch. 

 An extra box is so con- 

 structed as to get tele- 

 scopically into, and 

 slide easily in and out of 

 the main box on the 

 rear of the car. When 

 the hood is lifted and 

 folded back, this extra 

 drawer may be extend- 

 ed into the hood and 

 supported by it. In this 

 way an extensible box 

 is furnished which con- 

 siderably increases the capacity of a 

 runabout without decreasing its strength 

 or detracting from its appearance. 



A Non-Spillable Funnel 



A FUNNEL which will cease flow- 

 ing automatically when the vessel 

 into which the liquid is being poured 

 reaches a certain height, can be devised 

 by attaching a metal float to the tapering 

 funnel-tip. The float is a small metal 

 cylinder closed at both ends. Small brass 



tubes should be soldered on opposite 

 sides of the float, as indicated in the 

 drawing. Nails which will fit loosely in 

 the tubes (to give the float free play) 

 should be soldered at their points to the 

 tip of the funnel, with the float in place. 



When the funnel is filled the float rises 

 and stops the flow 



The extensible box is easily made and greatly enlarges the 

 capacity of the car 



When liquid is poured into the funnel, 

 it will flow past the float until the vessel 

 is nearly filled, whereupon the float will 

 rise and check the funnel's discharge. 

 The funnel can then be withdrawn quick- 

 ly, so that little or no liquid is lost. 



Mat-Making for Photographers 



TAKE a few spoiled plates and clean 

 off the film. Cut ofif four pieces 

 from a roll of passepartout, one for each 

 edge of glass. Paste these on the glass 

 along the edges, leaving an opening in 

 the center of the glass a little smaller 

 than the films or plates. 



In using this put the mask in the 

 printing frame first, lay the film or 

 plate on top, and print in the usual way. 



By making a number of masks with 

 dififerent size openings in the center, dif- 

 ferent size films or plates can be 

 printed. 



If a mask of special design is wanted, 

 paste the loose mat on the glass, as it 

 saves time, and also prevents the mat 

 from being lost, torn or creased. 



Passepartout tape can be bought at 

 any art store for lo cents a roll of 12 

 dozen yards. This will make all the dif- 

 ferent size masks wanted, and there will 

 be enough left over to passepartout a 

 luimber of prints.
