The Coe Veneer Knife Grinder. 



No phase of knife grinding presents so many 

 difficulties as does the grinding of veneer 

 knives. There is a vast amount of difference 

 between grinding a short planer and a four- 

 teen-foot veneer slicer knife. If a grinding 



The heavy cross-head on which the grinder 

 mandrel runs slides between parallel planed 

 ways, insuring for the stone an exact line of 

 travel without end-play or vibration. It is 

 fed back and fortn along the knife by heavy 

 steel feed screw. The machine is entirely 

 automatic in every way, and can be set so the 

 stone will only travel the length of the knife, 

 though this be much shorter than the full 

 length of the machine itself. The knife bar 

 to which the knife is attached while being 

 ground is one solid piece of iron, heavily 

 reinforced and incapable of spring. It is held 

 absolutely rigid during grinding so that there 

 is no possible chance for vibration. It is so 

 arranged as to permit a perfect adjustment 

 of the knife, and is fed toward the stone by

machine is not absolutely perfect in construc- 

 tion or operation, a cracked or burned blade 

 results, and the owner sustains a loss of any- 

 where from $50 to $350. 



For a number of years the Coe Manufactur- 

 ing Company tried to find a machine which 

 would satisfactorily grind its famous veneer 

 knives, but without success, and it was finally 

 driven to design one of its own to accomplish 

 the desired results. This machine should be 

 of particular interest to veneer manufacturers 

 operating slicers, as these knives are ex- 

 tremely hard to grind, and until the appear- 

 ance of the Coe machine on the market, have 

 never been satisfactorily ground. By using this 

 method perfect grinding is assured, and the 

 yearly knife bill greatly reduced in conse- 

 quence. 



In designing the machine illus- 

 trated in the accompanying cuts. 

 the Coe Manufacturing Company 

 broke away from old ideas and 

 worked along new and original 

 lines. The company believes this 

 machine to be the only one which 

 will always grind a perfectly 

 straight, true edge, and it is guar- 

 anteed to produce a perfect cutting 

 edge on the knife. This means 

 veneers of uniform quality and 

 thickness, and is an important 

 point for the manufacturer to con- 

 sider. 



In most machines the knife is 

 bolted to a carriage, which travels 

 back and forth past the grinding 

 wheel. At either end of the route 

 the knife carriage overhangs the 

 base of the machine several feet. 

 This construction cannot be made stiff enough 

 to keep the knife from springing, consequently 

 grinding is uneven and poor veneer results. 



In the Coe machine the stone travels back 

 and forth, while the knife is held rigidly in 

 place. There is no overhanging; the base of 

 the machine is as long as the machine itself. 



cut steel screws. The feed is entirely auto- 

 matic, and can he adjusted from 1-1000 of an 

 inch to 4-1000 of an inch for each travel of 

 the stone. The grinding mandrel is adjust- 

 able, so that the operator can grind either a 

 straight or hollow ground bevel. The frame 

 is made exceptionally heavy and strong, as can 

 be seen from the cuts. Cut steel gears are 

 used throughout, and on the mandrel drive a 

 rawhide pinion is used so that the machine 

 is practically noiseless. No belts or ropes are 

 used, except for the main drive: the machine 

 is self-contained and compact. It will grind 

 either wet or dry and to the full length of 

 knife up to 16S inches. Its long list of users 

 may l)e of interest to prospective buyers, as it 

 shows the popularity of this machine with 



A Handsome Gift. 



A remarkably fine example of inlaid work 

 in the form of a ruler was recently pre- 

 sented to Speaker Cannon at Washington. 

 The presentation w.as made by Congressman 

 Mann, of Chicago, on behalf of the skilled 

 woodworkers and artisans of the Pullman 

 Car Company, Pullman, 111. The ruler was 

 composed of 1,864 pieces of wood in mar- 

 quetry work, put together in a most artistic 

 manner. The expert artisan responsible for 

 this beautiful piece of work is Peter Lenzen. 

 The wood contained in tlie ruler comprises 

 hundreds of different varieties, and in its fin- 

 ished state shows nearly all the colors of the 

 rainbow. 



New Sulphur Process for the Preservation 

 of Wood. 



United States Consul K. M. Bartleman. of 

 Seville, Spain, gives an interesting outline of 

 a new process for the preservation of wood. 

 This question has been the subject of much 

 discussion and experimentation, and a new 

 system will doubtless prove of interest to many. 

 Mr. Bartleman says : 



"All the wood preservative methods now em- 

 ployed are defective in so far as they make use 

 of solutions the evaporative nature of which 

 makes their action upon the wood effectual only 

 for a certain time. The new method in ques- 

 tion, which has been patented in Germany, goes 

 further and utilizes a fixed body which becomes 

 solid upon being instilled into the pores of the 

 wood. This substance is sulphur, the physical 

 properties of which offer interesting advantages, 

 being fusible at about 115°, a temperature which 

 the wood can support without any perceptible 

 change. The sulphur is applied in liquid form, 

 and in hardening completely fills up all the 

 interstices of the fibrous tissue. 



"Although sulphur oxidates easily if subjected 

 to a high temperature, at a medium tempera- 

 ture it remains impassive, resisting not only 

 the influence of water, but also that of acids, 

 concentrated or diluted, and alkaline solutions, 

 if cold. The reason why the utility of sulphur 

 in the direction indicated had not been recog- 

 nized ere now was on account of its small 

 mechanical resistance, pure sulphur being very 

 brittle and pulverous. But as wood possesses 

 the quality of mechanical resistance of which 

 sulphur is devoid, the compound of these two 

 bodies may, under the proper conditions, 

 easily acquire valuable industrial properties, 

 as, for instance, the vulcanized caoutchouc, 

 which wood, impregnated with sulphur, re- 

 sembles a good deal. 



"To protect wood by means of sulphur the 

 following must be observed, viz: Sulphur is

fused in a befitting receptacle, making use of 

 steam to avoid an excess of heat, which de- 

 teriorates the sulphur. Into this liquid, and 

 at a temperature of about 140^, are steeped

 ment, care being taken to immerse them com- 

 pletely. The foam which gathers at first.
