SAW-SET.

Specification of Letters Patent.

Patented Feb. 28, 1911.

Application filed July 12, 1909. Serial No. 507,165.

To all whom it may concern:

Be it known that I, LoYD N. MEADOWS, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented a new and useful Saw-Set, of which the following is a I specification.

My invention relates to saw sets, and has for an object to provide a device of this character which will be adjustable to either a fine or coarse toothed saw.

One of the difficulties experienced with the usual form of saw set is that the set jaw strikes so near the point of each tooth that there is not a suiiicient set given to the tooth to prevent the saw from dragging when in operation.

My present invention overcomes this difficulty by the pro-vision of a disk-like anvil having a bevel formed on its periphery which differs at various points so that the rotary setting of the disk provides an adj ustable abutment for the set jaw of the too-l and which so positions each tooth in relation to the set jaw that it will be sprung from its base rat-her than from its point as in the usual form of saw sets.

vWith the above advantages and other objects in view which will appear as the nature of the invention is better understood, my invention consists of the novel details of construction and combination of parts illustrated in the accompanying drawing, described in the following specification and set forth in the appended claims.

ln the accompanying drawing, Figure 1 is a longitudinal sectional view of my improved saw set. Fig. 2 is a plan view of the same. Fig. 3 is a cross section through the line A-B of Fig. 1 looking in the direction of the arrow head. Fig. l is a sectional detail view through the longitudinal diameter of the gage disk. Fig. 5 is a similar' View taken at a right angle to Fig. L1.

In a more detailed description of my in- -vention in which like characters of reference designate similar parts in the views shown, 5 designates the fixed handle of the holding jaw which terminates in a head 6 having a longitudinal slot 7 in which the curved or movable handle 8 of the working jaw is pivoted. 0n the end of the handle 8 is formed the actuating or set jaw 9 which is substantially pyramidal in facial contour so as to adapt it to set teeth of various sizes and lengths. The set jaw is preferably removably secured in the end of the handle in order to facilitate its removal for repairs.

The head 6 terminates in a frame 10 whose ' sides 11 and 12 are recessed at their upper edges to form ledges 13. A screw 16 takes inwardly through the outer end 15 of the frame, and is adapted to bear against a supporting member and to adjust it longitudinally within the frame. Said member comprises an upper section 17 having lateral ribs 18 engaging the ledges 13, and a lower section 14 having lateral ribs 19 engaging beneath the lower edges of the sides 11 and 12. Passing loosely upward through both sections of the supporting member is a screw 20 having a winged head 21 fixed to its lower end beneath a washer 25 as shown, and its threaded upper portion extending' loosely through a circular boss 230 (depending from the center of an anvil 23) and engaging threads in a nut 22 fixed in said anvil. By these means the latter may be clamped upon the supporting member and the sections of said member simultaneously clamped upon the sides of the frame 10 by tightening up the screw 20, and when said screw is loosened the supporting member can be adjusted longitudinally within the head by the screw 16 and the anvil can be adjusted rotarily upon said member. The edge 24 of the anvil is formed on a bevel which differs at vari- ,ous pointsi around its periphery as seen in Figs. 11 and 5, and opposite such points its upper face is marked by index numerals some of which are shown in Fig. 2. In practice the index ligure on the anvil which corresponds to the number of teeth to an inch as usually stamped on the saw blade, is disposed toward the setyjaw 9 in order to bringthe proper point in the beveled edge 24 into position beneath said jaw so that it will coact therewith, after which the screw 16 is adjusted to bring said beveled edge more or less underV the set jaw according to how much of the length of the saw teeth it is desired to set.

For holding a saw blade seated upon the upper surface of the anvil a clamping member 26 is provided. The clamping member comprises a body portion 27 having downturned edges 28 which slidingly fit the sides of the head 6 and extend forwardly in prongs 29 and 80 which have their lower surface ofthe anvii/ andY prevent the saw from jumping or sliding when the pressure of the set jaw is brought to bear'upon its teeth. Y Y t Formedrin the body portion 2770i the clamping memberL isV a longitudinal slotfSl engaged Aby Vthe shank of aj thumb screw 32 seated in the head 6. The object of this con struction isto'V provide an adjustableV clampin'g'fmember that will securely clamp saws of different thicknesses inposition.. during the operation of the tool, thisv being eiected A `by( loosening-the thumb screw and sliding Y, thev clamping member lengthwise upon the tweenfthe beveled active edges of the prongs head. 6, thereby increasing the distance bei Y Vandv theanvil so that saws of various thick- V'nesses may be inserted therebetween.'

`VInorder tolimit the pressure ofthe set jaw upon the teeth'of the saw'blade, a stop .screw 33'is engaged thro-ugha slot't formed Vin the handle of the holding jaw and screwed p intor,.-afthreaded opening in the `actuating with 'the' forward yend of the slot preventing.

' of theholdingandactuating aw and serves to normally'ihold thefhandles spaced apart. i` A Y connectionwith'the accompanying drawing,

From the-foregoing description, taken in it is'thought that the construction and operg ation/of my invention will be easily understood without a moreextended explanation, 35V f *the form,proportion andminor details ofl it being understood that various` changes in vconstruction may be made without sacrificing any of `the advantages ordeparting fromthe spirit of the invention.

n VVhatis claimed is:

J l. Ina sawk set, the combination with two,a

pivoted'handles, and aset jaw `carried by one ot'V them; of a-head on the other -forming 'an open frame, a supporting'member i Y opies'of thisip'atent may be obtained for 'composed of two sections' having ribs mountfed slldably within the frame, a screw through. vrthe end of the'frame for adjusting said mem- .ber longitudinally therein, a disk-like anvilhaving its periphery beveled differently at various points, and a screw passing loosely through the sections of the supporting member at right anglesto said other screw and its threads connected with said anvil.

2. In a saw set, the combinationwith two pivoted handles, and a set jaw carried by one of them; ofa headzon the other forming an open frame whose sides have ledges along their upper edges, a supporting membern composed/of two sections mounted slidably within the frame, ribs on the upper section engaging said ledges, ribs on the lower section engaging beneath the edges of the frame, means for adjusting said memberlongitudinally within the frame, a disk-like 'anvil having its periphery beveled differently at various points, and a screw passing loosely through the sections of the-supporting member and its threads connected with said anvil. 3. In a saw s et,'the combination wlth two pivoted handles, and a set jaw carried by `one of them; of a head on the other forming anopen frame, av supporting member composed of two sections mounted loosely within the -:tra1ne, ribs'on the sections slid,- ably engaging saidlframaa;diskslilre anvil having itsv periphery beveled diiferently at rvarious points, a boss depending from its center and j ournaledin the upper section, a nut seated inthe anvil, anda screw passing loosely through both sections and said boss engaging said nut.
