Which Way Will the 



Tree Fall? A Machine 



Which Controls the 



Direction 



TREE felling machines 

 not only facilitate 

 the felling operations but 

 also reduce the hazard 

 and the consequent dam- 

 age. The machine shown 

 in the accompanying il- 

 lustration consists of a 

 pole, a plank, and a pair 

 of levers. The pole is 

 usually three to four- 

 inches in diameter, fifteen 

 to twenty feet long, and 

 often shod at the upperend 

 by a metallic socket armed 

 with a spike and at the 

 other end by a similar 

 but larger socket armed 

 with a toe and two 

 lateral projecting pins. The wooden plank is 

 about eight feet long, four inches thick, and 

 eight inches wide. It may be simply 

 notched regularly on the upper surface, so 

 that it presents an appearance similar to 

 an ordinary washboard, or it may be sur- 

 faced with a firm corrugated metal. At 

 regular intervals along each side of the 

 plank are about twenty-five projecting 

 pins. By pressing forward and upward on 

 levers and changing their hold the work- 

 men are able to move the base of the pole, 

 groove by groove, towards the base of 

 the tree. The levers consist of wooden 

 handles usually about five feet long. To set 

 up the machine the plank is laid upon the 

 ground with the grooved surface uppermost 

 at a distance of ten to fifteen feet from the 

 tree to be felled. In 

 case of large trees and 

 sometimes in wet or 

 snowy weather it may 

 be necessary to fasten 

 the plank to prevent 

 slipping. This can 

 readily be accomplish- 

 ed by driving a stake 

 into the ground against 

 the far end of the plank 

 or by tying the near 

 end of the plank to a 

 nearby tree, or even 

 to the stump of the tree 

 to be felled, provided 

 it is not being taken Hinge section 



By pressing forward and upward on levers, the workmen are 

 able to make the pole exert a strong pressure against the bole 

 of the tree, compelling the tree to fall in the desired direction 



out by the roots. The pole is then placed 

 against the tree in an inclined position with 

 the spiked end fixed against the tree trunk 

 and the other end armed with a toe resting 

 temporarily in a groove towards the far 

 end of the plank. 



Pull Out a Cigarette and a Lighted 

 Match with One Motion 



WHY should cigarettes and their 

 matches.be packed in separate pack- 

 ages? Why not carry them in one, and not 



two, boxes? 

 So thought 

 George E. 

 Lamberson, 

 of Brook- 

 lyn, New 

 York, and he 

 devised a 

 box to hold 

 cigarettes, 

 matches and 

 sandpaper 

 to ignite the 

 match as it 

 is drawn 

 out of the 

 box. 



The ordi- 

 nary cardboard cigarette 

 box is surrounded with a 

 thin wrapper, which serves 

 to hold the matches". 



A thin 

 wrapper on 

 the lid of 

 the ciga- 

 rette case 

 holds the 

 matches. 

 The ends 

 extend as 

 shown
