upon a carriage which oscillates in a substantially vertical plane about a fixed axis. Normally the toolholder is stationary relative to its carriage and the acting face of the tool is oscillated in an arc. When it is ded to give the tool a straight path, a device 'ought into operation which maintains he acting tool-tace in a straight line subs itiaily tangent'to its normal curved path. 5 Jul discussion of possible modifications will {he postponed until the specific mechanism l shown in the drawings has been fully described. v

provides thev recesses 18 for the-stops Q q tion by the propriately positioned recesses 13 on the ,means of the oppositely acting depressing 1 spring k. (see Fig. 3) and elevating springs i Z Z. The depressing spring lei'sconveniently given the form of a coil spring which abuts at its upper end upon a seat 10 supplied by the bottom of an adjusting screw 11 which threads into a part of the carriage b; and at provided by the arm 2'. The elevating springs Z Z, one on each side of the arm 2', are attached at one 1 end to the carriage and at the other end to said arm. A tool-holder m is supported on the outer end of the-supporting arm and is arranged to partake of such yielding as the arm 71 may have under the influence of the springs 7c and Z Z.

A cylindrical sleeve n rigid with the arm constitutes the immediate support for the' tool-holder which is so mounted as to be rotatable onsaid sleeve. The outer end of the sleeve n is screw-threaded to accommodate a nut 0 which serves to prevent displacement of the tool-holder lengthwise of The tool-holder being rotatable about the sleeve 11, it is desirable that some means be supplied for holding it in one or more predetermined positions. To this end a non-rotatable pin 2 is provided, extending through the sleeve 11., and having on its inner end rigid stops q g which project into ap tool-holder tosecure the latter against rotation. The stops qq are held in engagement with the recesses 13 by means of a spring 1', encircling the outer end of the pin 19, which abuts at one end against the sleeve n and at the other end against a head 8 on the pin 12. When it is desired to rotate the tool-holder, the head .9 is pressed inwardly to move the pin 1- and withdraw .the stops 9 g from the recesses 13, whereupon the holder is released and may be rotated at will.

For purposes presently to be elucidated the tool-holder comprises a body member and an auxiliary member B. The body member A supplies the hub of the toolholder which rides on the sleeve n, and also (see Fig. 4). A stud t projects fromthe body member to aiford means for attachingan edge setting tool T as shown in Fi 3. The auxiliary member B is bifurcated, iaving two parallel fingers C C arranged to fit easily in appropriately formed ways D D in the body member. (See Fig. 5). Thus the auxiliary member B is permitted to move relatively to the body member A. This in one direction by th'e C C contacting with the heads of screws to u, carried by the fingers C C, which" overlie steps 14 on the body member as shown in Fig. 6.. Sprin s E E are linterposed between seats ,stationary on the carria 'e A walls of the plate 00 provi ed respectively on the body member and the auxiliary member to cushion the movement of the latter relative to the former (see Figs. 5 and 6). springs are positioned in sockets 'u v ontthe body member. The effect of said. springs For convenience these E E is to ofier a yielding resistance to movement of the auxiliary member towardthe sleeven. A stud w for attaching a second edge setting tool WV is carried by the auxiliary member diametrically opposite to the corresponding stud t on the body member. By rotating the holder through one hundred eighty degrees from the position shown in Fig. .3, the tool W on the stud w will be removed fiom its lowermost station, which is l the'operative position for either tool, and

will be replaced by the tool T. It is customary to use different tools for setting shank edges and forepart edges and for the purposes of this particular machine it is preferred to attach the forepart tool W to the stud w and the shank tool T to the stud t, and either may be brought readily into operative position as already described. \Vhen the shank tool T is in' use the tool-holder is g 1), (except as it he moved immaterially under the inand the ath to edge; it is T 0 Hill liue iice' of the springs'lc and'l Z), tool-face moves 1n a convex curved suit the concave outline of the sham but when the forepart tool W is in use desired to give the tool a straight path.

this end a straight-path device is employed comprising a concave cam-face F an .a cooperating lug G. The cam-face F isconveniently supplied u on an edge of a plate arigidly secured to t e outer end of the nonrotatable stud a. The end of said stud a.

may be split and provided with a screw- 3 threaded aperture to receive ascrew y having a frusto-conical head which, when screwed inwardly on the stud a, serves to spread its split end to grip the. encircling tSsee Fig. 3). The lug (l, as shown in the Marin s, projects upwardly from the surface oft A and is rigid therewith. The lug is so positioned that its upper face contacts with the cam F when the stud w is lowermost and the forepart toolis in operative osition (see Fig. 3). The lower face of t e late a: is inclined on both sides of the cam- 1 to supebody member ply cams 2 which'serve an end presently to v lows: In setting a shank edge the shank tool T is lowermost. ,The lugGr. is out of engagement with the cam F which. therefore has no oflice and the tool oscillates in' a curved path. Thefsprings 7;: and -Z Z perm tthe tool to" yield in response to; irregularities on the we to absorb some shank edge and also se of the vibration oceasione'dby therapid movement of the tool. When it is desired to set the fore'part edge'the tool-holder is is thus given 2:

rotated, already described, to bring the toreparl tool Vi into operative. position and to bring the lug G into engagement with the cam F. the rotation of the toolholdor the loo; G- strilccs one of the inclined cams .2 2 whichi lacing rigid, causes said lug as it is further rotated to he depressed, thereby dopressingr tho entire tool holder and its sup porting: arm '5 thc tension of the springs Z, 7, until the lug G; leaves the cams and enters the concavity of the cam F, Whereupon said lug is forced into close. contact with said cam l by the springs Z Z acting through the supporting; arm i and he toolholder in. Thu when the tool-holder has been rotated 1 one hundred eighty degzcc. from its initial 3* rion tho forepnrt tool ll has been curried .nlo operative position and the 1 h dcvice has been properly assembled ,or giving the tool the rectilinear motion Which ensues from the folloivii'uz causes. The CUll It? remains stationary as the lug G o llates by reason of the osrillatii'ln of the e arms j j embracinglhc tool-lml-ilcr be con them. As the lool'holder approaches an extreme of its travel (indicated dian-rnmmi'icnlly by a line '15. '5" the lug G curried along a graduallv dcsccnding portion of the cam face F.

This forces the tool holder outwardly tor-:avd the out j j against tho itei When the tug (l reaches t extreme of its movement lt Wiil havehccn depressed to the position indicatcd by the line it; (Fig. 7), and at the same time tho tool I will have been depressed to the position shown by line 17'. The line i? is substnntiall tangent to the curved path 18 which would he taken by the tool, in the coin-so of normal oscillation with the. arms j j, if the straightdinc device were eliminated. As the tool-holder leaves its extreme position and begins its return movement he tool returns gradually to its initial position relativc to the guide-arms j in moving to its other cxtrcmc, the lug G is again depressed, the. acting face of the tool W being maintuinod all the while in the path indicated by the lill: 17, except as it may he removed therols-om inunuterially by tho springs E E yielding as licreinufici' d scribed. The tool rcciprocating movcincnt, and in llaii term reci irocating movement, as used in this specification and tho appended claims, is meant a backward and i'orward movem nt in is right line. By again rotating tho tool-holdw about the sleeve n the shank tool may he brought into notion and the straight-path oevicc disorganized so as to ho of no el'tcct. When the parts are in proper position for setting a forcpart edge it is cvidcnt; that. thc tool-holder itself is prcvented from yieldingupivardly by the rigid plnte .1 eu srag ing the lug (i; but the springs E- E, interposod between the body member A and the auxiliary member B of the tool-holder, serve as a yielding cushion for the forepart tool and in that regard per form the same oliice for the torepart tool which is performed for the shank the springs 7.: and Z Z.

The specific mechanism shown in the drawings has been presented for illustrative purposes only. and shows but a singl'e cn'n bodimcnt of the invention. Obviously a tool of any sort could be attached to the stud u:, and the cam F might be so slinpcd as to give to said tool any desired path. Several cams of ditlercnt sorts mightbe provided as shown, for example, on a platc X in Fig. 8. Said plate X might be. substituted for the plate :1! shown on the machine in the drawings. and the cams "20, 21 and (can ried by said platc X) could be introduced respectively, into engagement with the lug G, or other device, by looscning the screw 1 moving the plate Xso as to bring the desired cam into propcr station and then tightening' the screw 1 ()t' (-oursv othcr m nus for securing the plate X in position might be employed. such arrangement as the non-rotatable pin p with its stops 7 could be arranged to cnproperly positioned reccsses on the plate X. Also the cam might be carried otherwise than on a plate of this sort. Al though it is thought more convcnient to cmploy two tools of different varieties it is cvi dont that one tool could be omitted, and With the arrangement of the plate X just described the remaining tool could be given any desired paths of movement. All such modifications as are here suggested, and many others which will be readily apparent to those skilled in the art, are to be consid ered as included within the proper scope of this invention as itis defined in the subjoined claims.
