THE WOKLD'S ADVANCE for JULY 



That's a Handy Little 

 Vise for Tool Work 



You will find it convenient and reliable for 

 holding small pieces on the drilling machine, 

 for fitting or lading out work on a surface 

 plate and in many other cases. It is light and 

 handy enough so you can hold it in your hand 

 on filing and such work, and besides it is drop- 

 forged and casehardened, and rugged enough 

 to stand hard knocks. See the V groove in the 

 bottom, you can use it as a regular V block. 

 It's called the B. & S. Toolmakers' Vise, with 

 a capacity of 2 in. Read the full description 

 in free Catalog No. 26. 



Brown & Sharpe Tools 



are in the hands of mechanics, draftsmen, electricians, the careful, painstaking workmen 

 all over the world. The reputation of the many types of micrometers, verniers, rules, 

 squares, gauges, calipers and other shop tools has been passed on by the men who have 

 used them for years, because they found the same high standard of accuracy and careful 

 finish maintained on all tools with the B. & S. trademark. They 

 are tools you may be proud to own, because they are known to 

 be good for long, reliable service. Ask the hardware dealer for a

ANOTHER "SMALLEST ELECTRIC MOTOR" 



Another claimant to the smallest electric motor in 

 the world title is a machine built by H. F. Keeler, a 

 student in the Highland Park College of Engineering 

 at Des Moines, Iowa. The armature is less than 

 one-quarter inch in diameter, while the wire of the 

 winding is no larger than a fine thread. It is said 

 that a jeweler's microscope must be employed in order 

 to see the different parts. The entire machine weighs 

 only 20 grains, or as much as a third of a teaspoonful 

 of water. The motor operates on one dry cell.

 "Plier Pointers 



Look At These 

 UTICA PLIERS 



They have sharp cutting edges so finely tempered you can cut or pull apart a 

 twenty-penny nail without injuring the plier edges and then they will cut 

 a hair of the head. 



Behind Utica Pliers are 16 years of exclusive plier experience and 

 a satisfaction-guarantee that means something. That's why we 

 say there is one "best" in everything and that in pliers it's 

 "The Utica." We prove it or you return the tool and 

 get your money.
