t ie die-block to deliver heeLattaehing nails to the perforntions in said block.

A stationary block or projection 1-1 forms npzirt of the main trarne. At a point above this stationary block is arranged a verticallyJ movable block l2 adapted to slide'u-p and down in guides on the front ortion of the mnohine. (ln 'the top ol the block l2 is; supported the lower end of n vertical jack-screw 13, the upper end of whiclrworks in n female screw-thread in o jock-carriage 14, havin ways l5 on its up )er side on which' the jao 16 is adn )ted to slide out and in relative to the die-block Q. The jack-screw lf3 has g, pinionA l7 integral with its` lower end, the teeth of which pinion mesh in the. teeth of' n rack 18 whioh is adapted to slide horizontally in suitable guides. Seid ruck is operated by the try-.aille lever 19 to turn the )inion 17 and move the jack-carriage 14 an jack 16'upwardly until the. top of the sole t t the shoe Loaders 10 are pivoted on the 'first quarter revolution of the drivingheld in the jack is brouht in Contact with moving the jack upwardly automatic mech-.

anism may be employed in this machine to lace lan increased pressure on the jack durY lng the operation o driving the nails. This mechanism, may be also employed in the operation of spanking on the top lift. In the stationary block 11 is journaled a shaft 20,l and in the'movable block 12 is journaled 4a shaft 21', said shafts 20 and 21 having secured to them the cams22 and 23, respectively, having cam surfaces 24 and 25, and concen- v tric surfaces 26 and 27..' The said cams are operated from the rods 6 by means of levers 28, 29 secured, respectively, to the shafts 20 and 21, said levers 28, 29 being attached by links 30, 31 to adjustable blocks 32, 33 on rods 6. It will be understood that during shaft l, the cams 22, 23 are moved from the' position shown in Fig. 1, the engagement of the cam surfaces 24,v 25 in the movement of said cams serving to force upwardly the movable block 12 and the jackcarriage 14 to glace an increased pressure on the heel.'

uring the next quarter revolution of thev shaft 1 the concentric surfaces 26 and 27 are in contact, allowing the cams 22, 23 to rock without impartingurther upward movement to the jack, during which time the drivers descend and drive the nails into the heel' Dur-4 while the heel is held under pressure. ing the final halt revolution of the driving shaft the rods 6 and cams 22, 23 are returned to their normal position. Any suitable clutch mechanism may be employed to con-l 1 spanker plate 43 will be`brought evenly i1".

trol the rotation of the main shaft 1.

In the referred embodiment of my invention int e o eration of drivingthe nails I`v support the ieel obliquely with relation to the path of the nails by making the face of the die-block 9 inclined to the line of thev providing means to support the; ace in contact with the inclined f drivers, and heel with its face of the die-block. The inclination of the face jof the die-block may be conveniently secured by means of a removable wedge 34, Yhaving perforations 34 to register with those of the die-block. The inclination may bel changed by substituting for this wedge an other wedge. of different inclination. Any

suitable means for attaching the wedges to.; the die-block may be employed.

'lo support'the heel-with its upper face in contact with the inclinedface of the dieblock I may employ amovable work support 5 35 on the jack 16. This work support ishence with the face of the heel.

a ainst which the ends of' the nails are c enched.

To drive the nails tothe desired depth evenly over the entire heel the drivers may have their4 driving faces in a with the inclined face of the ie-block, and A conven ient form of nail driver block by which this arrangement may be obtained is shown in Fig. 2. In this construction the block is composed of two sections 38 and 39, the sec tion 38 having an inclined inner face and being 'perforated to receive the drivers, and the section 89 being ada ted to be secured above section 38 to hold the drivers in place. By making. th'e sections 38 and 39 with the same inclination as the face of the die-block the driving Vfacesyffthe drivers are brought into a' plane parallel to the face of the heel. In case a change is made in the inclination of the face of the die-block the drivers may be changed to correspond by substituting another driver block 1n which the lane of the driving faces is at the proper inc ination. It will be observed that the driver block is removably supported in the head 7.

The heel may be broughtinto osition to be nailed on the shoe by a rotata le carrier 40 having spring-pressed heel .clam s 41. On the carrier 4() are also rrounted t e top lift clamps 42 and spanker plate 43, The car' reir 40 is shown ivotally su ported on a member 44 carrid y the die-b ook 9. It is desirable to give the carrier -40 such a position relative to the die-block 9 that the contact with the inclined face of said dieblock when the carrier 40 is turned to bring a Atop lift into position above the heel, and that the plane'of the heel clamps will be substan-` tially parallel with said inclined face. This positionmay. be obtained by cm .loying a- .removable block 45 as an interme latel conlane parallel IDO 'f as obtained by the substitution of a block 45 and wedge 46 of suitable dimensions.

In the nail-driving operation illustrated on the drawings the nails 47 are driven in a par-V allel relation towards the rear of the heel and theirV points are clenched against the metal heel plate 35 of thework suppnrt. As the oints of the nail striliethe Vheel plate obiquely the lclenching operation -is accom plished with less liability of distorting or fracturing the nails, and, as will be observed, the oints of theA nails after clenching lie to- War s the rear ofthe heel.

i iace of the heel and a top lift may e spanked on the heel while the heel is in this condition. ln the o eration of spanking on the to Vlift the top ift clamps 42 carrying a top 4li t be# low the spanlier late 43ers brought into position beneath t ie inclined face of the die"- block or abutment 9 and aboveY the heel. T he heel is then brought into position by the treadle mechanism andthen pressed forcibly against the die-block by the cams 22, 23 so that the top lift is' s anked upon the exposed ends of the'nai s of the heel, as indicated in Fig. (i.

It will be seen that the top lift is forced u ion the ends ol thenails in a direction parallel to said nails.
