THE HARDWOOD RECORD. 



AN IMPROVED SWAGE SHAFEB. 



The Pribnow swage shaper, recently 

 greatly improved in design and utility, 

 has. it is claimed, incorporated in its 

 maive-up the combined advantage of the 

 ■ fifteen years' practical experience of its 

 inventor and of suggestions from many of 

 the best filers in the country. The com- 

 bination of the convenient and accurate 

 adjustments between the adjustable damp- 

 ing or shaping jaws 9 and 10, the adjust- 

 able tooth gauge 4 and adjustable back 

 guide 15 is the feature which makes the 

 tool indispensable to the modern mill man 

 or saw filer. 



The clamping or shaping jaws 9 and 10 

 are made of the finest tool steel and tem- 

 pered by a special process which makes 

 the working parts very hard, fit to cut 

 glass, but still they will not chip nor 

 break. The forward end of the clamping 

 jaws is beveled and comes in contact with 

 the saw tooth in such shape that it forms 

 a perfect chisel point, a perfect clearance, 

 and widest at the extreme point. The 

 clamping jaws clamp the tooth the entire 

 length, which action supports the shaper 



screw 14 till the points average even on 

 both sides of the saw. A novel feature 

 of tooth gauge 4 and adjusting screw 6 

 and adjustable tooth gauge holder play 

 an important part in this act. 



The tooth gauge 4 bears the same num- 

 ber on the end as the gauge of the saw 

 operated on. This tooth gauge is a small 

 round bar made of too! steel, the working 

 end being accurately fitted to a standard 

 I'jrm to straddle the swaged point, and 

 the sides have the exact form of a finishes! 

 tooth. A system is adopted so that each 

 tooth gauge is marked on its end with 

 the gauge of saw it is intended for, so 

 that if a proper gauge shall be used for 

 the saw in hand the best results will ue 

 obtained. For illustration, a No. 16 wUl 

 work on a 10-gauge saw. but a No. Ju 

 will not work on a 16-gauge saw. 



To adjust the tooth gauge, if the fin- 

 ished point shall be too wide, loosen set- 

 screw 8 and turn thumbscrew C to the 

 light; if the finished point be too narrow 

 turn the thumbscrew to the left, and so 

 on until the point is just right; then 

 tighten setscrew S. Another simple and

in line with the saw and assures accurate 

 shaping of the swaged points. It is essen- 

 tial to have the swaged points line up 

 evenly on both sides -of the saw to assure 

 a straight cutting saw, this defect being 

 most noticeable on double edge band 

 saws. 



After the shaper is placed on the saw 

 and a test shows that the teeth do not 

 line up evenly on both sides, if the 

 points line too heavily on the left side 

 the clamping jaw 10 is moved ahead by 

 adjusting setscrew 14: if the points line 

 too heavily on the right side of the saw 

 the clamping jaw 10 is let back by set- 



\aluable adjustment of the tooth gauge 

 in relation to the clamping jaws is em- 

 bodied in the adjustable tooth gauge 

 holder. As a rule, on band saws the 

 htJder is left up, as shown in second illus- 

 tration, 2, but a slight movement down 

 will bring the tooth in contact with a new 

 wearing face of the clamping jaws and 

 not change the gauge of the finished point; 

 in othfr words, on circular saws it is con- 

 venient to adjust the shaping jaws to a 

 diflereiit pitch in relation to the tooth 

 and in connection with the adjustable 

 back guide 15. The sectional cut show? 

 a No. 5 shaper mounted on a large cir- 



cular saw. The second cut shows the 

 same shaper mounted on a common band 

 saw. 



As a lule, the back guide is long enough 

 to cover two teeth besides the tooth oper- 

 ated on. If this back guide (15) shall be 

 adjusted so that the inner point is in touch 

 with the point of tooth gauge 4 the shaper 

 will slide along easily on the saw and 



THE IMPROVED SHAPER 



can be operated with one hand and does 

 not need a handle to steady it on the saw, 

 although there is a handle on the opposite 

 side from the clamping lever 2 for the 

 convenience of the operator. Back guide 

 15 is adjusted by adjusting screw 18 and 

 held in place by setscrew 13, so the shaper 

 works equally as well on a circular saw as 

 on band and gang saws: no matter what 

 diameter or width the saws may be nor 

 how far between points, with the handy 

 adjusting screw 18 the shaper can be 

 tilted, to suit any pitch of tooth. 



Grinding gauge 16 (also shown complete 

 ill larger illustration) is furnished with 

 each shaper. The clamping jaws are 

 placed in it as shown at 17, and thus ac- 

 curately ground and always kept smooth. 

 The clamping jaws are reversible so that 

 all four corners can be brought into use. 



This tool is made in three sizes, lor 

 saws ranging from 6 to 24 gauge. Manu- 

 factured by E. C. Atkins & Co., Indianap- 

 olis, Ind., leading makers of saws and
