 and among the board of directors are the well- 

 known lumberman of Grand Rapids, Mich., 

 John W. Blodgett ; James E. Danaher, a lum-

It is a big enterprise, but with proper manage- 

 ment, which it should have the prominent and 

 capable men involved, it should not only be suc- 

 cessful from the promoter's point of view, but 

 be a valuable adjunct to a good many worthy 

 commercial enterprises. 



The Grand Bapids Kilns 



The Grand Rapids Veneer Works are in receipt 

 liapids, Mich., builders of a model dry kiln ap- 

 paratus, seem to be putting in the larger portion 

 of the dry kiln construction going on in the 

 United States at the present time. They have 

 recently closed contracts with the Minneapolis 

 Furniture Company of Minneapolis, Minn., for 

 one of their kilns. Among other new equip- 

 ments just sold are one to the Knoxville Furni- 

 ture Company of Knoxville, Tenn. ; one to the 

 McLaughlin Carriage Company. Oshawa, Ont. ; 

 and to the Morgan Company of Oshkosh, Wis., 

 four kilns, which is a repeat order. 



The Grand Rapids Veneer Works are in receipt 

 of a letter, under date of April 16, from the 

 American Manufacturing Company, Sheboygan, 

 Wis., stating that the process has more than 

 doubled the concern's drying capacity, with halt 

 the steam consumption and time previously re- 

 quired, and that the lumber comes out of the 

 kilns without checking, warping or honeycombing. 



John B. Smith & Sons., Ltd., of Toronto, Ont., 

 under date of April 26, advise that they are 



drying lumber with exhaust steam, running nine 

 hours a day, as follows : Inch mahogany in 

 ninety hours, two-inch maple in one hundred 

 and twenty-six hours, inch oak in ninety hours, 

 inch poplar in ninety hours, inch pine in twenty- 

 seven hours, and two-inch hemlock in one hun- 

 dred and eight hours. 



The Williams Piano Company, Ltd., of 

 Oshawa, Canada, in referring to the Grand 

 Rapids new vapor process in a letter under date 

 of April 27, states that from the use cf these 

 kilns it has attained remarkable and economical 

 results. The company says it dries inch chest- 

 nut, birch, elm, poplar and maple easily in 

 ninety hours, and has dried two-inch elm and 

 spruce in ninety-nine hours, two-inch maple in 

 one hundred and four hours, and ail other woods 

 in proportionate time. This is done with ex- 

 haust steam only. The lumber comes from the 

 kilns soft and straighter than when put in the 

 kilns, the company reports, and there is abso- 

 lutely no checking from drying.

The Linderman Automatic Dovetail Glue 

 Jointer 



The past few years have seen such wonderful 

 development in machinery of all kinds that in 

 order to receive any great attention, apparatus 

 must now be of exceptional merit. Such a ma- 

 chine is being put on the market in large and 

 rapidly increasing numbers by the Linderman 

 Machine Company of Muskegon, Mich. This 

 contrivance, known as the Automatic Dovetail 

 Glue Jointer, is a vast improvement over all 

 other tools for accomplishing the work that it 

 does. It joints and joins lumber automatically 

 at one operation ; it takes the lumber from the 

 cut-off saw without the usual preparation, joints, 

 glues, unites automatically and edges the com- 

 plete panel to width at one operation. This, it 

 will be readily seen, is a great saving in labor. 



lumber, glue and time. At least half the time 

 required for stock to remain in clamps while the 

 glue set under the old method is saved by the 

 use of this machine. 



The new tapering wedge-dovetail glue joint, il- 

 lustration of which is shown herewith, is the 

 latest and most commendable achievement of the 

 Linderman concern, and is perhaps causing more 

 comment among woodworking men at the pres- 

 ent time than any method exploited for a con- 

 siderable period. This is not without reason, for 

 this machine insures perfect joining automat- 

 ically at one operation, forcing the glue into the 

 pores of the wood instead of allowing it to es- 

 cape. 



The tapering-wedge dovetail glue joint is 

 made in the same manner as the straight dove- 

 lail joint. The lumber is fed into the machine 

 from both ends on two endless beds traveling 

 toward the center, where it Is taper-wedged 

 jointed, glued, united and forced out to the 

 center operator automatically. He edges the 

 composite panel to width at one operation. . 



In uniting the tapering-wedge jointed boards, 

 they do not fit tightly but slide together loosely 

 until they are a few inches from the end. This 

 allows the glue to stay in the joint, the wedge 

 dovetails drawing the boards together quickly, 

 forcing the glue into the pores of the wood and 

 practically welding them together with a perma- 

 nent clamp. 



Exhaustive practical tests of this tapering- 

 wedge dovetail have been made at the company's 

 factory and at a prominent chair manufacturing 

 concern, and it has been demonstrated that this 

 is the strongest joint ever made, as it is impos- 

 sible to break a panel in the joint, showing that 

 it is stronger even than the natural wood. 



Interested persons can get samples of the 

 lapering-wedge dovetail joint on application to 

 Ihe Linderman Machine Company at Muskegon, 

 .Mich.
