The tube 8 is provided with a slot 24 arranged to registerV with a corresponding sl'otin the block 6 throughy which tacks are Vfed from a tack tube 26 leading from the usual tack separator. l

v .The tack driver l0 is carried by a driver bar 28 which is movablelengthwise in a guide member 30, the driver bar being connected at its upper end to anupwardly and downwardly movable driver head-32 the con- .struction and operation of whichware more fully set forth in my copending application.

' A spring 34 acts between the upper end of the driver b 'arj 28 and a pin 36 onthe guide :member to assist in imparting upward or retractive movement to the driver vbar. yIt

' will be understood that when, the member 32 l() to drive the tack. Y

is moved downwardly it imparts operative movement to the driver, bar and the driver `The tack holder, is positioned initially with its tack fingers 14 suiciently elevated downwardlytoward the heel seat, for ex` .to be clear of the wipers 4 in their movements over the heel seat, as shown in Fig. l, and 1n the tack drivlng operation is moved ample to theposition illustrated in Fig. 2.

Forv the purpose of such control of the tack Y holder thereismountedin aguideway in the member 30 at vone side of the driver bar tor movements in directions parallel to the direci .v `tions of movement of the driver bar a slide 38 Y which hasprojecting downwardly therefrom a plate 4() the lower endot which is bent into "position to enter aslot 42ormed inl one side I of the tube 8. The slide 38 is pressed downwardly by means of a'spring 44 and a plungagainst the wall ofthe recess in the member 3() in which the slide 38 is mounted. The

er 46 which are mountedA within a socket in the slide, the plunger bearing upwardly slide 38 `has thereon a projection 48 `which extends into a Vslot formed in the driverv bar 28 and in the upward or retractive movef ment of the driver bar is engaged byv -a shoulder 50 on said bar. to-` impart upward;

In the construction hereinshown such downward movement ot the tack lholder is limited by engagement of a projection V52 on the slide-38with a shoulder 54 formed Von the member 30. The tack holder vis thus Y Y Leashes moved yieldingly toward the` work, under control of the driver bar, by the action of the spring 44 and moved away from the work by 'positive engagement of thecdriver bar Vwithft-he projection-48.
