The Policeman and the 

 Fainting Lady 



WASHINGTON police, 

 experienced in hand- 

 ling big crowds at presidential 

 inaugurations and other cele- 

 brations in the national Capi- 

 tal, recently set about to find 

 a way to revive persons who 

 have fainted on the street 

 without having to call an 

 ambulance and send them to 

 a hospital. Now every mem- 

 ber of the force when on duty 

 in crowds carries in his pocket 

 a pill-box full of tiny glass 

 tubes of aromatic spirits of 

 ammonia. The tubes are 

 about an inch long and 

 slightly more than an eighth 

 of an inch in diameter. Each 

 has a wrapping of absorbent 

 cotton and over this a silk gauze covering. 

 Slight pressure between the fingers is 

 sufficient to break the tube. The ammonia 

 is promptly absorbed by the cotton about 

 it, which also serves to prevent the sharp 

 particles of glass from doing any harm. 

 Held beneath the nose of the person who 

 has fainted, the fumes of the ammonia soon 

 revive him. The tubes are stored in all the 

 patrol boxes about the city and are carried 

 in patrol wagons and police ambulances.

The conveyer reaches eighteen feet into the box car and 

 piles the coal in the far end of the car without breaking it 



A Conveyer Which Loads Coal in 

 Box Cars Without Breakage 



IT is difficult enough to bring coal to the 

 surface, but marketing it in good-sized 

 lumps is a still harder problem. If the coal 

 leaves the mine in large lumps and is 

 delivered in small lumps, having been 

 broken in freight cars on the trip, it suffers 

 a depreciation in price of about thirty 

 per cent. This is one of the discouraging 

 factors that the shippers of -coal have 

 had to contend with for years. 



Box-car loaders of various 



kinds have been used with little 



success. Mechanical shovelers 



disposed of the coal in short 



order, but they broke it badly. 



Now comes the conveyer type 



of loader, designed to load the 



coal without breakage. It does 



not throw the product it is loading 



but carries it to the end of the car, 



as shown in the illustration. It reaches 



eighteen feet into the car, fifty per cent 



further than any other make of loader. 



The conveyer is supported on two arms 

 hinged from a post in such a manner as to, 

 be easily moved into a box car by hand. 

 The chute is on the lower side of the car and 

 follows the loader in all positions. At the 

 receiving end of the belt loader is a de- 

 flector which turns the coal as it comes 

 from the chute in the direction of the con- 

 veyer, thereby reducing the breakage. The 

 conveyer is tilted by turning a crank.
