The double spray for fertilizer cuts down 



the farmer's work one-half. The same 



machine can be used for planting 



Fertilizing Two Rows at Once 



THE farmer or gardener can speed 

 up his Spring work by putting fer- 

 tilizer into two rows simultaneously in- 

 stead of merely doing one row at a time. 

 A bifurcated fertilizer spout makes it 

 possible for one man to do the work of 

 two. The device may be attached to 

 any ordinary fertilizer distributer, and 

 its spouts will deliver the fertilizer in 

 opposite directions to the two rows. In 

 some instances planting might also be 

 done in double-quick time with this in- 

 genious device. 



Taking Off the Tire in a Jiffy 



A TIRE tool, invented by John P. 

 Cunningham, of York, Nebraska, 

 simplifies the usually troublesome under- 



taking of removing an automobile tire 

 from the wheel-rim. It is especially de- 

 signed for use in connection with clinch- 

 er tires. One person can brace his foot 

 against the spoke and easily and quickly 

 pry the tire off with this tool, without 

 soiling his hands. 



The device has a bar, the inner end 

 of which is attached to a ring which fas- 

 tens around the hub to act as a brace. 

 The outer end of the bar has a peculiar- 

 ly-shaped lateral offset portion, which is 

 inserted between the edge of the tire 

 and the flange of the rim. An operating 

 lever is used by the autoist in conjunc- 

 tion with the other device. The lever 

 has tongues that engage mid-way on the 

 I)ar of the device that extends from the 

 hub and engages under the tire. The 

 offset portion of the device is worked 

 along the tire by a rotary prying move- 

 ment. It is then held securely by a 

 ring device that engages around the hub. 

 Then the autoist takes his auxiliar}' lever 

 in hand, braces his foot against the 

 spoke, spins the wheel around and off 

 comes the tire. 



It is almost equally useful in replac- 

 ing the tire. The only difference is that 

 the tire casing goes inside the upper lug 

 of the offset portion of the tire that 

 swings about the hub. The wheel is 

 turned the same as in removing the tire. 

 The offset lug, being on the outside of 

 the casing, forces it over the rim into its 

 proper position. 



With this tool a clincher tire can 



be pulled off quickly and without 



damage by one person
