Have you 

 thought of it? 



npHE Director General 

 of Railroads recom- 

 mends, that owing to the 

 extreme difficulty in mov- 

 ing freight during the 

 coming winter and pos- 

 sible restrictions on the 

 movement of traffic ex- 

 cept for the most essen- 

 tial operations, all manu- 

 facturers should stock up 

 now while movement is 

 comparatively open with 

 sufficient supply of mate- 

 rial to carry them through 

 the winter.

determine is brashiness. This is usually indicated by light 

 weight. It is also tested for by gouging out pieces with 

 the point of a knife and noting whether it splinters or 

 breaks off short. 



After the laminations have passed inspection they go 

 to the glue room and are put into a hot box for about an 

 hour. The temperature of this box is kept at that of the 

 glue, from 140 to 150 degrees F., and the humidity is 

 about 40 per cent, though practice varies in this regard. 

 The best grade of hide glue is applied to the hot boards 

 and care is taken to see that there is a uniform distribu- 

 tion. The laminations are placed in a form and blocked 

 up, after which they are clamped tightly and put aside 

 for from I 4 to 24 hours to allow the glue to set. Various 

 clamping devices are in use, some specially designed, 

 others the ordinary furniture clamps. 



After the glue has set, the propeller blank goes to some 

 sort of machine which roughs it out, though in some in- 

 stances this work may be done entirely by hand. There 

 are various machines employed ranging from an ordi- 

 nary cutter head to which the blank is fed by hand to the 

 elaborate wood-carvers which shape four blades at once. 

 One form is the copying lathe such as is used in the manu- 

 facture of gunstocks and various other forms of turned 

 wood. A roller follows the "original" or pattern and a 

 reciprocating arm carries a cutter head which shapes the 

 "work" or blank. This leaves the "work" rough and 

 requires much more hand labor to finish than some of the 

 other machines. 



An automatic propeller shaper is being manufactured 

 by the J. A. Fay & Egan Company of Cincinnati under 

 the Wadkin patents. This machine is used extensively 

 in England. It consists in the main of a traveling car- 

 riage bearing two reciprocating arms, the upper carry- 

 ing the cuttter head and being guided by the lower with 

 a roller which moves back and forth over the form and 

 cradle. Both the "original" and the "work" remain 

 stationary. The stock is prepared for this machine in the 

 rame manner as for hand work except that the long lami- 

 nation extends a little at each tip and has a hole bored to 

 template at each end. It requires about 45 minutes to cut 

 out a propeller on this machine. 



The propeller shaper made by the Mattison Machine 

 Works of Beloit looks quite different from the one just 

 described, but operates on the same principle. The pro- 

 peller is held stationary while the cutter is reciprocated 

 back and forth over it, shaping one side at a time. It is 

 adapted for handling three- and four-bladed as well as 

 the two-bladed propellers. The makers claim that only 

 4 horsepower is required to drive the machine. 



A simpler type of machine built by the Starr Piano 

 Company of Richmond, Ind., differed from the fore- 

 going in that it was designed to cut with the grain of the 

 wood in order to eliminate the cross-waves left by the 

 machines which cut across the grain. Owing to the fact 

 that the propeller capacity of the country has been so 

 increased that additional machines are not required this 

 company has withdrawn theirs from the market.
