I 3 JIM Em flz all Witnesses v Inventor Attorneys 'MEANS iron SHAPING THE RnKERgTEnTii or sAWsf 7 To all whom it may concern! I I Be it known that I, JQSEPH' M. E iERIoK, a citizen ofthe United States, residing at Salem, in the county of Marion and State of; Oregon, have invented anew andfuseful; Means for Shaping the Baker-Teeth :of

Saws, of which the following specification. gr r c The presentinventlon apperta ns to-saW sets, and aims 'toprovide anovel andTiin; proved device of; that o character" adapted especially for use with, crosscutsaws. 3

It is the Object of the inventionto provide an implement jof the nature indicatedl having novel means for" engaging and "accommodating the saw, having novel means i,

for shaping the "rakerteethp having novel means for holdingafile" to file the points of the ftee'th," and having [other] improved features to thereof.

With the foregoi 1g and other c ots; in view which will appear "as the description proceeds, the invention "resides'in the combination and arrangement of parts and in thedetails of construction --hereinafter de scribed and claimed, it" being -nnderstood. I I

In carrying out the invention,,there*is provided an elongated body which will'bef e referred to as disposedlongitudinally of the implement, said bodybeing preferably cast from suitable-metal and having a base plate 2 at one end to fit either side offin saw. The plate has the laterally projecting wings 3 projecting toward opposite sides, and similarly projecting secondary wings 4 between the ends of the body, while the wings 3 arelocatednear the lower end of the body. 'The body 1 is provided at its other end with an outstanding boss 5 having a longitudinal axis arranged approximately 3 g V sideoftheplate. enhance the utility andeflioiency p p A i i l i l ap'plled to the saw,;and to facilitatetheap-g ie. .1 @1311 be e i ste l gitudinal y,oi themselves and ul y a ou diithebqlt w 12 as gpivots, in orderlthat the hooks l i I is pl ced against one side of thelsawblade i view, showing a portion Specifieationof Lttersfiatentfi p te tdju y 2, 1913f Qlipplieation filedMarch15,191 7,'S erlaIi\To.i55,042., l i 5:

points 'offthe saw teeth, the wings 4: are provid'edf with rearwardly projectinglugs 17v 5- I threaded;v Thus, when' a' file orielongated. abrasive member 19: is placed'against the H faces of" the bars 7 adjacent to their rear f edges',;the screWslS can be screwed toward thefile to clamp it against said bars, as seen through which clamping screws 18: are

in Fig.2. Then, when themembers are removed or reversed. so that their hooks 14' will not interfere with the movement of the device, the device can be reciprocated. along the saw with the bars 7 "sliding along the points of the teeth and with theplate 2 I sliding along one side of the blade. The file 19 is thereby carried along the points of they teeth for filing the points thereof, and the device can be applied to both sides of the saw, as will be apparent.

The boss 5 is provided with a'longitudinal 22 has ahead 23 upon its outer end adapted to be struck by a hammer or' other suitable implement. An adjustable nut'21'is thread- "ed upon the plunger 22 between the head 23 and boss 5, and a coiled wire "expansion" spring 25 surrounds the plunger and is confinedbetween the nut 24: and the bottom of the counter bore 21 whereby to move the ;plunger"- 22 outwardly or upwardly by adjusted to regulate tl le tension of the;

i the plunger22 is a swage 26 slidable along spring tension. The spring 25 is seated in the counter bore 21, andthe nut'2 1 can be spring. Engaged upon. the inner end of the body or frame 1 between the boss 5 and the plate 2; The swage 26 is secured tOLthe plunger 22 "by means of a set screw 27 or otherwise, and is provided with beveled por "tions"2 8"to engage the points of the raker tooth 15 andbend them apart and bring themin-to proper position. Thus, when the device is applied to the saw, a's'indicated in Fig. '3, thehead 23 being struckwith a hammer, will force the swage26 against'the tooth '15 between the points thereof, and the beveled portions 28 wil-l'setthe points of said-teeth, the blade being retracted from the toothby the spring 25."

The device is also provided with means for bending the teeth toward opposite sides to setflthem, and for 'this'purp'ose, the body or" frame'member 1 is provided .at that end which "hasthe boss 5, with an outstanding anvil 29- opposite to the boss. The anvil 29 has a surface 30 against which the saw blade or tooth is adapted 'to "rest, ai'id'be-"j you'd the surface 30, the anvil has an inclined surf-ace 31 sloping from the surface '30, asf

seen in Fig. 4. Above-the surface 31 is mounted a swage member or head 32 having lugs 33 pivoted to lugs 34C upstanding from the anvil 29 A spring 35 tends to raise or move the member'32 away from the surface 31, andthemember;32 is provided with a beveled portion 36 to move adjacent to and parallel ;with the surface 31 when the 1ne1nber 32 is struck by a hammer or other suitable implement.- By placing the saw upon the anvil with the pointed end .of the tooth overhanging the surface 31, the member 32 can be struck by a hammer, and will hand the point of the tooth against the surface 31 The saw can'be reversed to bend the teeth toward opposite sides'as will. be ob vious.

Having thus described the invention,.

what is claimed asnew is 1. A deviceof the character described, embodying a body having-a plate, clamping elements carried by said plate, slotted hold ing members adjustably engaging said elements and having portions to engage a saw at oppositesides of a rakertOOth, and a swage movably carried by the body and engageable with r the end of saidtooth.

device of the character described, having plate to bear againstone side of a saw and a memberin a plane, at right angles' to said plate to contact with the points of the saw teeth, means engageable with-the saw for positioning said plate relative thereto, and a swage movable against the end of one tooth.
