SAW SET.`

Application led. July 1,I

To all whom it may concern.'

Be it known that I, HENRY B. RiiYNoLns,

a citizen of the United States, residing at Lathrop, in the county of Pickens and State of Alabama, haveinvented certain new and useful Improvements in Saw Sets, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in saw-sets and more particularlyto a device.

of this vcharacter/for setting the teeth of cross-cut saws. y A

An important object ofthe invention is to provide in this .type of device a construction which isreadily portable and which may be readily secured to anysuitable convenient support, asa table, the trunk of a felled tree, or the like. t A further object of the vinvention is to,

provide a deviceof this character in which the construction is very simple and iii which all adjustments arereadilyeffected, so that the use of tools not readily had in lumbering camps andthe like is unnecessary to replacement ory adjustment of partsas, for

example, removal of the anvils orthe like.

A still further object` of the invention is to provide a novel and improved'means for maintaining the saw set rposition upon a convenient support.

These and other objects 1 attain by the construction shown. in the accompanying drawings, wherein for the purpose vrof illustration is shown a preferredembodiment of my invention and wherein l Figure 1 is aperspective of a saw set constructed in accordancewith my invention; l v

Fig. 2 is a longitudinal sectional view therethrough;

Fig. 3 is a transverse section therethrough; and` j y v Fig. l ,is a detail perspective showing the mounting of thelow'er vanvil member. A

Referringrnow more particularly tothe drawings, the numeral 10 indicates a base which is formed from a'length of bar yiron of suitable size, one end ofthe' bar being slotted, as at 11. Adjacent the opposite end of the bar, at points spaced longitudinally of the bar, vertical threaded openings v12 are formed. In these 'openings vare first threaded` the shanks of calks l13, so that the ends of the calks project beyondthe lower surface of lthe A'bar for al considerable dis' tance The calks are then vsecuredagainst 1924. Serial No, 723,556.

movement by means of threaded 4plugs 14C having screw-driver slots so thatf they may: be '.rotated. These plugs lock the calks against movement and insure a proper posi? tioni'ng thereof and at lthe same time permit mounting of the vcalks sufficiently loose to` permit of their readyremovalat 'any :time when they should be replaced. These calksmay .be driveninto any y supporting.'` surface, as desirable, to maintain tion thereagainst. f

At a point spaced slightlyfiom the furcated end of thebar 10 a socket -lis formed receiving the shank of a lower anvil.16. ThisY lower anvilv is provided uponits iside face with aH projecting rib 17, which engages the base 'in posiin a channel 118 formed in the rside `wallJ-'of the socket 15 to 'prevent rotation 'of the anvil. Theupper vsurface of the bar, be-

tween this socket and the slotted'end .11, is

provided with a further socket 19 inffwhich engages the lower end of a pin, the purpose of'which is to prevent displacement of a spring 2O.` v ,f i

This spring abuts one arm of a bent lever 21, which arm substantially' 'parallels' the i barf 10. Theotlier arm 22 roofjthe lever has areduced extensionf23` fitting in thev slot 11 and held in vposition therein by a pivot pin v24. This reduced extension has a tailfpoi tion .25 which, by its engagement with'tliesupport against which'the lower surface of the bai' 10 is placed, will limitjthe separation ofthe free end of the arm21lof theleverffrom the bar. i

This free end ofthe llevei is provided,

alignment with the anvil 16,'withwa bore 26, i

through lwhich vis ydirected an upper.' anvil member 27 forjcoaction with the lower anvill 16.A- This anvil is providedA adjacent its upper 'end with Aa'notch28. *'The free end of the arm 21, between the bore '26 and such end, is vertically slotted," as at'29, and hasv notch v28 of vthe upper anvil member 27- in 71'05 such manner asto supportY-the'upper sur.4 fa'ce of the anvil member above the `upper surface'of thelever arm-21 to afford a striking face; i This bolt likewise serves the purpose 'of clamping the arms,`formed by slottiii'g at 29, together sol that the upper anvil is firmly' secured in .position inl the socket; l

` Ai-gu-ideI -32`1is provide'dcontrolling' 'thev` position of the saw. with respect to the anvils vend of the sheet.

16 and 27. This guide is in the Vform of a sheet of metal having a central slot 33 receiving the arm 21 of the leverand the base, vthis slot opening through the lower At the sides of the slot, at the lower end theieof, the sheet is flanged,

as at 34, providing bar engaging wings fitx ting closely against the side faces of the bar, the upper ends of these wings having angular portions 85 overlying the upper surface of the bar. In the bar engaging wings are formed slots 36 extending longitudinally ofthe bar, and the bar has extended therefrom place to place, be prevented Thisy prevention of excessive movement c islikewise necessary when the surface upon which l the .barlO is placed is lrelatively soft, as

repeated engagement of the tail piece 25 of the extension 23 against a soft surface would tend to form or gouge an opening thereink permitting such excessive movement.

Inrthe use of the device the teeth of the saw are lplaced between the anvils and the head of the upper anvil 27 struck with a hammer to effect the setting. Priorto a setting yoperation the gauge is, of course, set so-that the teeth .will extend between the anvils the proper distance. It will be obvious that when a different pitch of anvil is j desired o1" when in use the anvils become battered orworn, it is a comparatively simple operation to remove the anvils and replace them. f l v It will furthermore be obvious that this construction is capable of a certain range of change and modification without materially departing from. the spirit of my invention and I accordinglyvdo ynot limit myself tosuch specic structure as hereinbefore set forth except as hereinafter claimed.
