(o1. vrt-"zzo" 1 '1l-hef:presentvv invention relates to new- and use improvements in. saw sets' of' a,> type as cov ered. in; my prior U.. S.. Letters Patent No. $141,695', dated. lllecernber‘Z’lv, 1938'.V An importantv object of the present invention is to~ provide a saw set of: the-` aforementioned character in which a tooth-setting jaw is pro~ vided having anA elongatedI head adapted to con" tact the beveled side; of. the tooth. for' exerting pressurey thereon during the saw setting` action., the head of the.` saw setting jaw being adapted fon use with fine. or' coarse. saw teeth and em. b‘odying means: for adjusting the.: head of; the set’ ting jaw in` accordance witlrtha character of the tooth being set.- ` A further object of the present» invention is to provide a springeactuated Wedge adapted to grip the side of the saw for holding the same ñrmly while the teeth are being set. A further object“l of the invention is to provide the section 2 and the section-2 has a ilat upper end disposed in abutting relation with the shoul der 5,_ aswell as a fiat inner face 6» for disposal in'face-to-face Contact with the ilat inner tace ‘I of the section> I. The sections»3 I1 and 2 are detachably secured to each other‘by: a bolt `8` which extends through the section I and is threaded in the section 2..v The lower" portions of each of the sections," are 10 reduced. and provided> with flat confronting-faces disposed in spaced-apart' relation- with respect to each other for receiving a- saw- blade 9' between the' same and the opposed face of. the section- I has ar recess I-Ilf formed therein and in whichl is slidably mounted a wedge block. Ict yieldably urged; downwardly toward. the lower end. of.Y the section. I` by a coil spring I-2 toset.- up frictional wedging action against the saw blade. The inner portion of the spaced confronting faces of the sections are formed with registering a device of this character of simple and prac ~recesses I3 and I4, respectively, the recess I3 hav tical construction, which is eiiicient and reliable ing a setting jaw I 5 mounted therein of elongated in operation, relatively inexpensive to manufac construction and formed with beveled upper and ture and otherwise well adapted for the purposes lower edges I6 and I'I, the beveling I6 being rela for which the same is intended. 25 tively wider than the beveling I7, as will be ap Other objects and advantages reside in the de parent from an inspection of Figure 1 of the drawing. hereinafter described and claimed, reference be The jaw I5 is formed on a square shank I8 ing had to the accompanying drawing forming slidably mounted in a complementary shaped part hereof, wherein like numerals refer to- like 30 passage I9 in the section I and projecting from Darts throughout, and in which: the shank I8 is a screw 20 on which a nut 2I is tails of construction and operation as more fully Figure 1 is a side elevational view of the saw threaded and retained in a chamber 22 in the set with parts shown in section and illustrating section I with the edges of the nut projecting the tooth-setting head in use. outwardly at opposite sides of the section I, as Figure 2 is an edge `elevational View thereof. indicated in Figure 2 of the drawing, to provide Figure 3 is a vertical sectional view taken sub finger-gripping means for the nut to adjust the stantially on a line 3_3 of Figure 1. head I5 into and out of contacting engagement Figure 4 is a transverse sectional View taken , with one side of the teeth 23 of the saw 9. substantially on a line 4-`-4 of Figure 1. Positioned in the recess I4 is an anvil 24 like Figure 5 is a vertical sectional view taken sub 40 Wise of elongated construction formed on its stantially on a line 5-5 of Figure 1, and illus square-shaped shank 25 from which a screw 26 trating the anvil-carrying section. projects for manipulation by a nut 2'I carried Referring now to the drawing in detail, where in the section 2 similar to the nut 2l of the sec in for the purpose of illustration I have disclosed tion I and adapted upon manipulation of the nut a preferred embodiment of the invention, the nu 45 2l to move the anvil toward and away from the meral I designates the jaw-carrying section, while the numeral 2 designates the anvil-carry ing section, The section I vis relatively longer than the sec tion 2, the section I tapering toward its upper r end, as indicated at 3, and terminates in a ñat surface to provide a striking head 4 to receive a head I5. As illustrated in Figure 3 of the drawing, one side ofthe wedge I I is provided with a laterally extending pin 28 projecting outwardly of the The section I is provided with a shoulder 5 at .section I through an opening 29 for releasing the wedge from the saw, when desired. In the operation of the device, the saw blade '9 is positioned between the spaced-apart con fronting faces of the lower ends of the sections the junction of the tapered portion thereof with t I and 2 and the wedge II is moved downwardly hammer blow by a suitable tool. - 2,409,311 4 3 by the pin 28 to cause friction gripping engage ment thereof with the saw. The teeth 23 of the saw are disposed between the head I5 and handle 24 so that upon striking a hammer blow upon the striking head 4, the the body, spring means engaging the wedge to urge the latter into friction gripping engage ment with the saw, said body having an opening therein adjacent the wedge, and a pin carried by the wedge and projecting outwardly of the beveled edge of the setting jaw I5 will bend the body through said opening and providing finger teeth of the saw against the anvil at the de sired angle. Either of the beveled edges I6 or l1v may be gagement with the saw. gripping means for releasing the wedge for en . 2. In a saw set, a body comprising spaced brought into contacting engagement with the 10 inner faces to receive a saw blade therebetween and a saw tooth receiving chamber at the inner teeth of the saw in accordance with the size of the teeth being set. It is thought from the foregoing description that the advantages and manner of operation of the device will be readily apparent to those skilled in the art. ' ' It is to be understood that' changes'~ may be» made in the construction and in the arrangement of the several parts as herein described and i1' lustrated in the accompanying drawing, provided 20 that such changes fall> within the scope of the ends of said faces, a tooth engaging jaw embody ing an elongated head mounted for lateral move ment within said chamber, an anvil mounted for lateral movement within said chamber and co operating with said jaw, means for adjustably moving said jaw toward and from said anvil, and means for adjustably moving said anvil toward and from said jaw. 3. In a saw set, a body comprising spaced in ner faces to receive a saw blade «therebetween and a saw tooth receiving chamber at the inner appended claims; ends ofthe faces, a tooth engaging jaw embody Having thus described the invention, what I ing an elongated head'mounted‘ifor lateral move claim is: 1. A saw set comprising a body havingspa‘ced 25 ment within said chamber, an anvil mounted for lateral movement within said chamber and inner faces'to receive av saw blade> between» the cooperating with said jaw„means for adjustably same, and avsaw tooth-receivingv chamber atïthe moving said jaw toward and from said anvil, inner ends of the faces, a tooth-engaging jaw means for adjustably moving said anvil toward positioned atv one sidel ofi saidy chamber, saidI jaw being of elongated constructiony withzits` opposite 30 and from said jaw, one of said faces being pro vided wíth an elongated recess adjacent its lower ends> beveled forl selective engagement with the end thereof, and a wedge yieldably and slidably tooth of the saw, an anvil-positioned in the cham mounted within said recess adapted for fric ber atthe oppositesid’eof the tooth, independent tional gripping engagement with the. saw when means for adjusting the jaw and the anvil rela tive to each other, said body having a striking 35 positioned within said faces to secure the latter against movement. head adapted for receivingl a- hammer' blow at one end thereof, a wedge slidably mounted in EDGAR PLATTER.
