A Clipper Representing Modern Developments in Veneer Machines

Band saws have had other improvements than that relating to 

 safety. Their motors were first belted from the floor, then belted 

 on a bracket in a self-contained manner, then geared, then mounted 

 by means of a coupling, and now we have the motor arbor band 

 saw^. 



This may be as appropriate a place as any other to mention saw 

 sharpeners. There has been a wonderful improvement in saw 

 sharpeners. Most of the old hand filers and use of the hand gum- 

 mers have been done aw^ay with in favor of the 

 automatic saw sharpeners. The use of the auto- 

 matic saw sharpener has become quite universal. 

 Motor drive has been applied to the saw sharp- 

 eners in a self-contained manner. All belts have 

 been guarded. They have, in sum, reached a 

 high state of development. 



For the grinding of knives, gouges, chisels, 

 plane bits, and other woodworkers' tools, the 

 grindstone has very largely given way to the oil- 

 stone grinder. These oilstone grinders are built 

 with and without knife grinding attachments and 

 they are now offered direct-driven from electric 

 lamp sockets and in belt styles. This is a little 

 development of the last twelve months, but it 

 is appealing to the woodworker very rapidly. 



One institution recently purchased twenty-two of these, one for 

 each of its shops. The oilstone grinders have all the advantages 

 of the old style grindstone, that the cabinetmaker used to have on 

 his bench, multiplied by all the advantages of any power tool. The 

 oil is so introduced on the inside of the cup wheel as to penetrate 

 on the inside of the wheel and it works its way out so as to keep 

 the wheels constantly clean. 



Emery wheels, or emery cones, are usually furnished with these 

 oilstone grinders, so as to work on the inside of gouges and on tool 

 grinding. 



Knife grinders are now built with motor directly mounted on the 

 emery w^heel spindle or shaft. 



Exhaust Systems of First Importance 



No survey of improvements in furniture manufacturing equip- 

 ment could claim to be even superficially complete without some 

 consideration of the high development and importance of exhaust 

 systems. Today no woodworking plant can really claim to be up- 

 to-date unless it is equipped with an adequate exhaust system for 

 removing the sawdust and shavings as fast as made by the machines. 

 Modern high speed woodworking machines produce such tre- 

 mendous quantities of refuse material that unless this waste mate- 

 rial is removed as fast as it is made, it clutters up the machines 

 and surrounding floor space, necessitating frequent stops to clean 

 the machines and clear away the refuse. This results in lost time 

 and increased labor charges. Also, where the chips are not re- 

 moved by a suction system, they clog the cutters and this results 

 in pitted stock. 



The woodworking people are coming more and more to realize 



that an efficient and economical exhaust system requires a careful 

 study by experienced blow pipe men, and also, the power saving 

 obtained by the use of high efficiency fans, together with a properly 

 designed system, is a factor of tremendous importance in these 

 days of close competition. 



Improvements in Veneer and Panel Methods 



There is one line of development in furniture manufacture 

 which is of major importance, but which has not yet been touched 

 upon, because of the desire to wait to take it up at such place as 

 would permit of a more or less extended development. This refers 

 to the matter of veneers and plywood and the machinery for the 

 handling of them. 



"The use of veneer and plyw^ood in the furniture industry has 

 had a w^onderful development during the past ten years and equip- 

 ment and processes for the manipulation of veneer have gone 

 through a change equally as great," said L. G. Merritt, of the 

 Merritt Engineering and Sales Company, Lockport, N. Y., in an 

 article on "Notable Improvements Made in Handling of Veneer 

 and Plyw^ood During Last Decade," which appeared in Hard\voocI 

 Record April 25. "For one thing," Mr. Merritt continued, "peo- 

 ple in general have come to realize to some extent that w^ithout 

 veneered surfaces it would be impossible to produce the expanse of 

 figured wood we get now-a-days and the advantages of plyw^ood. 

 as compared with solid lumber are now recognized. With this 

 recognition has come new^ methods and new ma- 

 chinery for veneer and veneer work." It is a 

 fact, that the use of veneers and plywood is one 

 of the most characteristic and marked develop- 

 ments in modern American furniture manufac- 

 ture. 



In the matter of glues alone marvelous strides 

 have been made in the last decade, and the speed 

 of the development was greatly accelerated by 

 the World War. Due in great measure to ex- 

 periments made during the w^ar casein and other 

 glues have been brought on the market w^hick 

 have proven to be more or less water resistant 

 and which, therefore, maintain their holding^ 

 pow^er w^hen exposed to a certain amount of 

 moisture. There are highly improved vegetable 

 glues, and albumen formulas which, with the casein glues, have 

 largely usurped the field held ten years ago by the animal or hide 

 glues. All these glues have contributed largely to the development 

 of the improved present day methods of manufacturing furniture.
