tho manufacture and construction of thousands 

 of machines of the same class. It displaces the 

 previous widely copied N'o. 2 tenoning machine 

 made by this company, and. while retaining all 

 the valnalilp features of its predecessors, lias 



metal ; those for the teuou-head spindles are 

 six inches long next to the heads and five 

 inches long on the outer ends. The belt eom- 

 peusating tightener of the spindles is also self- 

 adjust ing to all positions of the belt. The copes 



The special advantages in the line of new 

 construction and improvement are certain t» 

 make the present machine as great a favorite 

 with the trade as have been Its predecessors.

added many hitherto unanticipated improvements. 

 It is especially suited for tenoning sash, door 

 and blind work, for use in the cabinet depart- 

 ments of car shops and for all general cabinet 

 and joinery framing. The frame is of iron, 

 massive and pedestal in form, with base 30x34, 

 wide enough to support all projecting parts. 

 The extension for supporting the table is curved 

 from the operator so as to admit of following 

 the work through the cutters, and a chute is 

 cast within the frame for directing the shavings 

 to the outside. 



The table is the chief advantage, being an 

 improvement over any hitherto made, and is 

 the feature which gives superiority to the ma- 

 chine. The principal advance in construction 

 Is the application of the roller bearing. The 

 table must always move square across the ways 

 because the rollers are connected together and 

 kept square or parallel by a guiding or riding 

 frame. Therefore, if the rolls move at one end 

 they must also move at the other, and hence 

 the whole carriage must move, no matter where 

 it is taken hold of or how much weight is upon 

 it. A man could sit upon the table and the 

 operator could take hold of the outer end of 

 the gauge bar, and with two fingers move the 

 table in either direction, perfectly sijuare the 

 entire length of the ways. The rolls next to 

 the cutter head are grooved to prevent end 

 motion, and all are protected perfectly from 

 shavings. They are also provided with leather 

 scrapers for removing any accumulating dust. 

 The table is quite heavy, so that it cannot spring 

 when clamping the work on, and has a traverse 

 movement of thirty-three inches, the roller bear- 

 ing moving only slightly more than one-half 

 that distance. The end of the table or carriage 

 next to the cutters is provided with a covering 

 that extends below and adjusts to a projection 

 on the ways, so that the table cannot lift up 

 when operating. The table is provided with the 

 usual clamp for holding the material and also 

 with a gauge bar of usual dimensions. 



The headstocks are substantial and movable 

 up and down by two screws so arranged that 

 they may be moved in either direction, both at 

 one time or separately, thus perfectly controlling 

 the size and position of the tenon. The cutter 

 spindles are all made of high carbon steel, 

 turned and ground accurately to perfect round- 

 ness. The bearings are all compensating and 

 self-lubricating and lined with the best Babbitt 



are attached to the main headstocks and adjust 

 with them, but they have both vertical and 

 lateral adjustments controlled by suitable screws 

 with hand wheels. The tenon-heads may be 

 used double or single and have Tl-o-inch cutting 

 circle. When the machine is fitted with double 

 heads it will cut tenons as long as six inches ; 

 when fitted with single heads it will cut tenons 

 only as long as 3 ','2 inches. The upper and 

 lower heads expand or separate to take in stock 

 as thick as five Inches, and the table movement 

 will, admit to cut tenons on stock as wide as 

 20 Inches by 1 inch thick. By passing material 

 through twice tenons may be cut as long as 

 eight inches. The knives are placed on the 

 heads so as to make a smooth drawing cut, and 

 are readily ground to the required shape. A 

 cut-off saw may be applied to the rear. The 

 usual equipment is supplied with this machine, 

 consisting of wrenches, cutter heads and cutters. 



Concerning the Atlas Engine Works. 



Perhaps the foremost builder of high-class 

 power plants in the United States is the Atlas 

 Engine Works of Indianapolis. It is said that 

 this company builds the most complete line of 

 engines and hoilers made by any one manu- 

 facturer in the world. . 



The H.iRDwooD Record is in receipt of the 

 company's latest bulletin. No. lai. on the At- 

 las single valve engines, which is now ready 

 for distribution. It will be found a very inter- 

 esting and instructive document for all users 

 of engines, and can be had from the com- 

 pany on application. 



Incidentally, there have been several changes 

 in the executive force of the Atlas Engine 

 Works of late. Death has overtaken E. T. 

 Hannam, the inventor of the Atlas water tube 

 boiler, one of the best known of the com- 

 pany's power plant equipments. Mr. Hannam 

 died on Saturday, Aug. 18, at Chicago, of heart 

 disease, and at the time of his death was 

 assistant manager of sales of the water tube 

 boiler department. 



J. P. Johnston, recently sales manager for 

 the Weber Steel Concrete Chimney Company 

 of Chicago, has become sales manager of the 

 water tube boiler department of the Atlas 

 Engine Works, with headquarters at Indian- 

 .ipolis. 



The company's Chicago sales offices which, 

 for several years have been located in Suite 

 930-902 Fischer Building will, upon the com- 

 pletion of the new addition to this structure 

 in November, be iticreased by the addition of 

 several large offices. Frank H. Baker Willi 

 continue as the manager of the Chicago office 

 and will be assisted by J. F. Davis, formerly 

 located at the company's Pittsburg office. 



Howard E. Troutman. for several years man- 

 ager of the Chicago office of the Buckeye En- 

 .gine Company, has become the sales manager 

 of the Corliss and high-speed engine depart- 

 ment of the Atlas Engine Works, with head- 

 quarters at Indianapolis, and J. M. Broucher 

 of the Brownell Company, Dayton, C, goes 

 to the big Indianapolis concern as assistant 

 general manager of sales. 



New One-Knife Shavings Grinder. 



In the cut below is shown the new oneknlfe 

 shavings grinder or hog, designed for cutting 

 up shavings ffom hardwood flooring scrapers. 

 The machine has been put on the market by A. 

 F. Bartlett & Co. of Saginaw, Mich., manufac- 

 turers of the well-known sawmill hog or edgings 

 grinder and other sawmill machinery. The ma- 

 chine is attached to the scraper by a hood and 

 (onnected directly with the blower system. As- 

 the shavings pass through the hog, they aTfr 

 cut up in such a manner that they can be easily

together with a countershaft, with tight and 

 loose pulleys. 



The machine shown In the illustration is 

 known as No. 225Ce. The style Is double heads 

 with two copes and the weight 2,000 pounds. 

 The floor space required is 6 feet 8 Inches by 

 .5 feet, and the average horsepower Is from

blown to the dust collector or directly to the 

 boilers. The machine Is built in one plec?, 

 allowing a free delivery to the blower pipe. It 

 has a hinged door on top which allows the oper- 

 ator to get a good view of the working parts 

 and to make any necessary adjustments, and has 

 au outside bearing which makes it a very smooth 

 running machine.
