rod from coming out of its bearings. To 

 prevent the oil gushing out through the 

 slot cut in the brass tube a glass tube was 

 inserted within, its diameter permitting a 

 close fit in the hole of the brass tube. The 

 length of the glass tube brought it into 

 position so that the cap B clamped it in place.

The markings on the outside of the tube

 tank were determined by turning a }/£

An Emergency Repair on a 

 Leaking Water Pipe 



THINGS often break down at the 

 most inopportune times. A num- 

 ber of years ago, the writer was called 

 upon one Sunday morning to stop a 

 leak in a cold water pipe which 

 threatened to ruin the ceiling below. 

 No plumber was to be had. The leak 

 could have been stopped by shutting 

 off the water altogether ; but for several 

 reasons this was impracticable for 

 any length of time. I had a supply of 

 friction tape such as is used by 

 electricians for wrapping spliced wire 

 joints. Shutting the water off in the 

 cellar for a few minutes, I wrapped the 

 tape closely over the hole, putting on 

 several layers. Over this tape I wrapped sev- 

 eral thicknesses of twine of which a plentiful 

 supply was on hand. When the water was 

 turned on, the leak was found to be com- 

 pletely stopped . The tape was left on the pi pe 

 seven days and answered well until a perma- 

 nent repair was made. — W. S. Standiford. 



THE tired shop-girl who is compelled 

 to board a crowded car every day will 

 appreciate this little hanger which she can 

 carry in her pocket or bag. It consists of 

 two large bone rings, such as are used by 

 harness-makers, connected by a half-yard 

 strip of strong webbing or tape, which 

 can be quickly slipped through the usual 

 hanger without inconveniencing another 

 passenger who may be using it. Both 

 rings are to be held together in the hand. 

 The short woman who has difficulty in 

 reaching the usual hangers will also find 

 this convenient. — J. E. McCoy. 



A Garage Air-Compressor Made from 

 an Old Automobile Engine 



AS an air-compressor was badly needed 

 in our garage, in spite of the fact that 

 the quantity of business did not warrant 

 the purchase of a high-priced machine, 

 we built one from an old discarded engine 

 from a small car. The engine had its 

 water-jacketed head broken in half. On 

 account of this only two cylinders were 

 used for the compressor. The old counter- 

 shaft and two pistons were assembled and 

 bolted down to timbers. A heavy flywheel 

 was keyed to the end of the shaft and this 

 was belted to the line shaft of the garage. 

 This outfit easily kept up from ioo lb. 

 to 135 lb. pressure. To hold this pressure

An old engine mounted on a wood base and driven 

 by another engine for use as an air-compressor 



a tank was constructed from a 10-ft. length 

 of 8-in. gas main, which, being capped 

 at each end, had an inlet and an outlet 

 hole drilled in the caps. With this equip- 

 ment the garage has ample air pressure 

 for all purposes in the shop besides free air 

 outside for tire pumping. — L. A. Bennett.
