To all whom it may concern:

Be it known that l, GI-IARLES P. S'rANnoN, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in Knife-Mountings for Sole-Rounding' Machines, of which the following description, in connection with the accompanying drawings, is a specification, like character-son the drawings representing like parts. v

The invention to be hereinafter described relates to solo rounding machines, and more particularly to the knife mounting in such machines whereby the sole is trinnned or out to the pattern, as usual in this class of inecliines.

It-ha-s been proposed heretofore to fixedly mount the knife or cutter upon :1 plate which was itself adjustable, so to czirry the cutting edge of the knife into proper relation with the axis of support or the knife carrier As will be readily apparent from such construction, the knife was not adjustable independent of esrry ing plate toward and from the axis of the knife carrier louse.

1n the present invention the aims and purposes have been to provide a construction whereby the knife or cutter might be readily adjusted independently of adjacent parts, in order to bring the cutting edge into proper POSilJ-l0l1,,21ll as will hereinafter more fully appear in connection with the follow ing description and accompany in drawings of one form of means for carrying the invention into pructicul effect.

In the drawin s: FHYIII'Q 1 is u detached detail View showing the knife mounting end the felulion of the knife to the patterns or clumps which hold the sole to be 'lrinnncd; Fig. 2 is u detail plun VlGW oi the knife and mounting indicated in Fig. i; Fig. 3 is it section on the line 3--3 of Fig; 1, the lower oortion of said section being broken away; lig. i is a detail perspective view of the knife; Fig. 5 is a detail perspective view of the knife washer; and Fig. (5 is a detail perspective view of the knife carrier block.

Referring more particularly to Figs. 1

and 2 of the drawings, the knife carrying I arm 1 is of usual construction and has piv- Otally mounted thereon the knife carrier block 2, said block being provided with lugs 4: 5 F 6 for receivinp' u in 6 E i 2 "9. w 7 0 CD 9 7 c 1 tin which serves as the pivotal support connect ing the carrier block 2 with the arm '1, as wi l be readily understood, the construction being such that the block 2 may swing upon its pivotal connection with the arm 1. The upper portion oi the block 2 is provided with u transversely extending shoulder 7, Fig. 6, forming shove the lug i a recess 8 for the reception of the knife and knife washer, us will presently appear.

The knife carrier block 2 is provided with a straight bearing surface 9 against which the s :lece 1.0 ol 'u washer ll, Figs. 2, 3 and washer being preferably pro vided near its lower portion with an offset or extending lip portion lladupted to engage a corresponding undercut portion 18 in the block .2 Figs. and G, the lower face of the portion 12 being adapted to slide on the oppo o hoe portion 01": the carrier block, as will be readily apparent.

The carrier block 2, near-its upper portion, is provided with islet 14, end the knife washer 1 is provided with a, corresponding slot 15, said slots being for the purpose of receiving eknife clumping screw 16 Fig. 3, us ,will hereinafter more fully uppeer.

The knife ispreiin'ubly formed as indicuted in Fig. 4 and comprises a base portion hev n corrugations or like projections and recesses l8 in one face thereof, said corrugations 18 being adopted to engage like corrugations 19 in the face of the knife wsshcrll, as imlicuted in Figs. 2, 4t and. 5. The knife hose 1? is also provided with a screw-tine .ded aperture or recess 20, adepted to receive the correspondingly screwthreuded end 21 of the screw 16 for holding the knife indiriduully in its adjusted position. Projecting upward from the knife hose 1! the k e blade or cutter 22, the edge c which is adopted to act upon the sole S held between the clamps or patterns P, Fig. 1.

From the construction thusferdescribed it will be uppurent than, upon loosening the screw 16, the knife may be readily unchnnped and reudjustcd with relation to the knife washer 11 to bring into engagement other corrugated ortions of the co-ecting surfaces of the knifebese and knife washer, and. that,.upon setting up the screw 16 and bearing the knife firmly against the knife washer, the parts may be held in their readjusted position. It will be noted that the knife washer 11-is not a carrier for the knife but rather an interposed washer having corresponding corrugated or projecting portions on its face which engage like corrugations or projecting portions on the adjacent face of the knife base, the purpose being to maintain the knife in proper adjusted and vertical position. By reason of the extended bearing portion 12 of the knife washer, all strain which is placed upon the knife or cutter 22 during the cutting" operations is transmitted to the knife carrier block and the knife and washer are thus maintained in their proper vertically disposed position with relation to the knife carrier block.

The knife carrier block is provided with an interiorly screw-threaded recess 24 which is engaged by an'adjusting screw 25, Figs. 1 and 2, the flanged head portion 26 of E which is adapted to engage the rearwardly projecting end 27 .of the knife washer 11, the construction being such that the flanged head portion of the screw 25 serves to hold the Washer in position, in addition to the clamping action of the knife clamping screw 16.

By making the knife'washer 11 independent of the knife, and the latter adjustable to ,carry the knife edge into proper position with respect to the axis of support of the knife carrier block independently of any movement of the knife washer, it will be obvious that the knife may be readily removed for the purpose of grinding and be adjusted, irrespective of any adjustment of the knife washer. Likewise, by having these parts ind pendent of each other and the knife .washer interposed between the knife base and the carrier block, different characters of knife washers, both as to size and disposition of the corrugations in the surface thereof, may be readily substituted the one for the other in order to enable the knife edge to be properly positioned with respect to the axis of the knife carrier block. For

instance if it be desirable to adjust the cutting edge 23 of the knife outward from the carrier block, or to the left Fig. 3, it is only necessary to substitute for the knife washer another of somewhat greater thickness, and if. it be desired to give greater nicety of adjustment of the knife edge 23 toward or from the axis of the carrier block, it is only necessary to provide a knife washer and knife base with the character of corrugations or projections and depressions suitable to this end, as will be readily understood by those skilled in the art.

In order that the knife carrier block, which as usual is spring pressed toward the work supports or patterns P, P, may have -a proper bearing surface against one of these work supports or patterns, a bearing spring 28 is provided, Fig. 2, said spring being clamped in place by a proper clamp ing screw 29 and the end portion of'said spring being carried around, indicated in Fig. 2, in front of the knife base 17 \Vhat is claimed is:

l. A knife holder for sole rounding nachines, comprising in its construction 'a pivotally mounted knife carrier block, a knife having a knife base provided with corrugations in one face, a knife washer having a corrugated face and interposed between thev knife base and the knife carrier block, and a screw engaging the knife base for drawing the knife base into holding relation with the knife washer and knife carrierblock.
