Mark Your Golf-Ball with Your 

 Initials 



A MARKER 

 used for 



stamping the in- 

 itials of the own- 

 er on golf-balls is 

 shown in the il- 

 lustration. Either 

 t w o , three, or 

 four initials may 

 be marked. The 

 type is inked by 

 rolling the pad over it ; then the lever is 

 pressed firmly down, the middle finger in 

 the ring giving sufficient purchase. If 

 desired, the ball may be marked in two 

 or more places. 



The marked balls are very useful in 

 preventing disputes as to ownership on 

 crowded public courses, but also serve 

 to clear up doubtful points as to owner- 

 ship of lost balls and the like on private 

 grounds.

Interchangeable Motor-Car 

 Grease-Capsules 



IL holes on 

 automobiles 

 are a thing of the 

 past and the 

 later screw-down 

 grease-cup, now 

 universally used 

 o n automobiles, 

 is apparently 

 doomed to oblivion because of an ex- 

 ceedingly simple and efl:ective device in- 

 vented recently by an Englishman. It 

 consists of a collapsible lead capsule, 

 which is screwed on to parts that need 

 grease lubrication, in place of the grease 

 cup. Finger pressure on the capsule is 

 sufficient to force grease into the bear- 

 ing or part to be lubricated, and when 

 the capsule is emptied a new, ready-filled 

 one is screwed in its place. The old 

 one is thrown away. No dirt, no grease, 

 no loss. 



The screw-thread, which takes the 

 capsule and keeps it firmly during trav- 

 el, is fastened to the part, instead of the 

 grease-cup. It is made of brass and 

 forms a grease-tight joint. Most of the 

 parts lubricated by grease-cups are out 



of sight on the automobile, but even 

 where visibility is desirable, the collaps- 

 ible tubes can be used. It would be nec- 

 essary to provide them with light brass 

 or plated caps, where they are in exposed 

 positions. 



New Device Distills Water 

 for the Home 



FOR the house- 

 w i f e who 

 wishes to make 

 sure that her fam- 

 ily is d r i n king 

 pure water, a new 

 water-distiller, re- 

 cently placed on 

 the market, 

 should prove ac- 

 ceptable. The de- 

 vice is made of 

 copper and is 

 lined throughout 

 with tin, as this 



metal is chemically unaffected by distilled 

 water. The still consists of three drums, 

 which comprise the boiler, the reservoir 

 for distilled water, and the condensing 

 chamber. 



To obtain distilled water, the boiler 

 and the cold water chamber are filled, 

 and the still is placed upon the stove. 

 The distilled water falls into the 

 reservoir through a water seal. This seal 

 is an important improvement, because it 

 confines the steam from the boiler, thus 

 increasing the pressure in the condens- 

 ing-chamber and gi^■ing twenty-five per 

 cent more condensation for the same 

 amount of heat. The distilled water 

 may be drawn off at any time through 

 a faucet, the water in the cooling- 

 chamber flowing into the boiler to take 

 the place of that drawn off*. 



Deep Center-Punching 



IN the boiler shop, where heavy cen- 

 ter-punching is done, as on heavy 

 tank and boiler heads and plates, the 

 layer-out may save time and physical 

 energy by the use of a center-punch that 

 fits into a light pneumatic calking ham- 

 mer. This can be easily made from any 

 of the various air-tools that have been 

 discarded.
