The'arrn 19 yhas-its other end fitted on the squaredrpart 21 of the rod v 16 andV locked thereon by the nuts 22 and-23. In 'order'to adjust the tension-ofthe hack-Y saw 17 the army 18 is preferablycoimected by the pivot 24C to one end ofthe arni 25 which latter has its other 'end fitted; and suitably locked on the squared part 26 at the upper part of the rod 16, and a suitable screw 27 is mounted on the arm 25 and has its lower endpart lpassed freely through the slotted rear end28of the arm 18 and provided with

abutnients

29 and 30 adapted to; bear against therear end part ofthe arm 18 when'rthe screw-27 is adjusted by turning it onv the arm 25.

To the wristpin 31 disposed-on one, side 1 hasconnected thereto the @sprocket wheel 35 which is driven :by the sprocket chain 36 andis 'secured Atothe sha ft 37l which isi Vsuitably mounted iii the bearing-38 which is mounted on the brack'etr39V on theflower` part ofthepostlO.V v k; As shown in'this Ainstance the heely clamp# ing device consists of the upper vplate 40 andl the 'lower' 'plate 41, `which "plates are adapted to fit in the crease between the heel seat and the heel of the shoe 42; the lower plate 4l being secured by screws 42 to the.

bar 43, and the upper plate 40 being disposed on one side of the eccentric cam 44 which is mounted on. the stationary pivot 45: and is provided with the operating handle 46. The bar 43 is preferably formed with the upright extension 47, and with the horizontal forward extension 48 at the upper end of upright extension 47.. j

The pivot 45 is connected to the forward end part of the extension 48. A facing-.491 of;l rubber` or other suitable materialisE provided. on the. cam 44 to prevent slipping on or mai-'ring of the heel et'.I the shoe 42 when the camr isin engagement with. theV heel.,

The heel clamping deviceis mounted. on thezdovetailz guideO to one end of which ad.-

jacent to the hacksaw 17 is suitably securedk ed in a. guideway which is provided.I inthe.

table. 5lA which latter is connected by thel pivot. 52. toj the table 53 which has on its. underside the dovetail guide 54. which is. slidably tted. in a corresponding guideway in the shelf 5,5 whichis preferably pivotall-y connected to the post l0. As shown, the shelf 55 has suitably secured toits underside the lug 56 which is provided with thehandle 57 and is: mounted on the pivot 58 in the bifurcated upper end ofy the. post l0.A

The gui-de 50 and heel clamping device carried thereby is moved transversely to the tableV 53 and towardor away from the hacksaw( 17 by the. lever 59 which. has. its rear endfconnected by the pivotl 60 to the lug 6l on the table 511.7 and is provided;- with a han.- dle 62 on. its forward end.; sa-id lever 59y being provided. with-.a longitudinal slot 63- into which extends a pin 64 attachedto the guide. 50.. When the guide is. adjusted in position by the lever 59 it is locked in position by means of the projections 65v which are provided on the underside of the lever 59 and are adapted to fit inthe notches 66 which are provided in the upper part of the table 5l.

The latter has. on its underside the dog. 68 which is mounted on the pivot 6.9 and has one end thereof adapted to tit inthe notches 70; provided. in the end of the lateralextenf sion7l ofthe table; 53. A spring72 is ein terposed between the handle 67 and the dog 68 andv is adapted to press the dog 68 into engagement with theextension 7l to lock the tablejl in adjusted position.

The handle 57 can: be: locked in adjusted position by means of the dogf-73 which is slidably mounted on the spaced lugs .74 and 75 on the handle 57 and is adaptedtoenga-ge the teeth 76 on the post10;the dog 73 being at the forward end of thershelf. 55 and is.

coimected-vv to the-table 53 by the curved link 83 which has one end pivotally connected to the angular levervSO- and has its,4 other. end connected to .the pivot 84. on; the` table. 5.3i.

From the. foregoing,` description. the; con-.Yy struction, operationV and` advantages. of; the.-

apparatusz will be understood by those.

skilled inthe art.` It willi be seen that the.

heelA or the shoe42 is placed on. the platei4l, to: have the; latter disposed in the creasel hay tweenv the: heel and the. heel seat of; the. shoe,

and then. the. handle 4 6 isY pulled upwardly to have thepl-ate 40 disposed inthe. crease and. thereby the.y heelcl-amping devicel according to; they amount that. it is desired. to cut. olii of the heel.` It itY isfdesired'. tof'makevan angular cut longitudinally of theheel, the tabley 5l can. be turned horizontallyby the handle 67 to have. the heel. disposed at-the desired angl-etez the--hacksa-.w 17. It itA is der sifredto make an angular cutitransverselfy of. the. heel, the. shelf. 55.. can be tilted to..have the heel disposed at vthe desired angle.- to the hacksaw 1 7.V By. operatingthe lever 80 the table 53 can be moved to eiiect movementoi the,- heel. past the hacksaw. 17 to have the latter cutv the heel.

The construction which hasr beenparticuf larly illustrated and. described adm-its oli niinor changes and modifica-tionse-wherefore they right is reserved to all such changes and modications as do not depart from. the spirit and scope of the invention whichis defined in the appended claims.
