CHARLES W. GLIDDEN, OF LYNN, MASSACHUSETTS.

. IMPROVEMENT IN NAILING OR TACKING MACHINES FOR BOOTS AND SHOES.

Specification forming part of Letters Patent N o. 197,213, dated November 20, 1877; application filed v April 30, 1877'.

To all whom it may concern: I

'Be it known that I, CHARLES W. GLID- DEN, of Lynn, county of Essex and State `of Massachusetts, vhave invented an Improvement in Nailing or Tacking Machines forBoots and Shoes, of' which the following is a specication: f

This invention relates to nailing or` tacking machines for boots and shoes.

.This machine uses a comb-like tack-strip,`

preferably Tv-shaped in cross-section, each tack or nail being severed singly from the strip just as it is to be driven.

In other machines -using a comb-like tack or nail strip the strip has been moved in the strip-guide by means of afeeding mechanism; but in this invention the strip-guide is pushed backward from the nail tube or foot, preparatory to' each descent ,of the driver, 'thereby moving the guide along the strip, the latter Y being held so as not to movebackl with it.

Figure l represents, in sectional elevation,

a hand tacker or nailer provided with my in- A sleeve-like handle, f, surrounding and moving longitudinally 'over the head, has pivoted or otherwise secured to it, at h, a strip-guide,

g, shown as curved and provided with-a T- shaped passage for the tack-strip. v

- When the sleeve fis held up from the shoulder i, as in Fig. l3, the end of the strip-guide, then in its highest position, projects forward into the opening 1jin the foot d far enough to place the point ofthe rst tack at the lower end of the strip beyond the upper cutting-edge of the stationary knife 7c, forming one side of the tack or nail tube passage.

When the sleeve is lowered, as in Fig. 1, the strip-guide, descending with it, places the iirst one of its Y- tacks within lthe passage ein the foot, and in line with the driver. i As the 'bar b descends, a cam thereon acts -upon a movj able stud and throws the strip-guide back,

. moving it over the nail-strip. The strip-guide,

as the nail reaches its lowest position, may be prevented from moving forward towardthe knife far enough, as the sleeve rises, to cause the end of the strip to strike the knife and push lback the strip by means of a springwedge, fm, which slips in behind the arm Z2 of the strip-guide, and between it and the head, and which remains there until the sleeve and strip-guide rise far enough to lift the end tack of the strip above the knife. When the guide rises far enough for its shoulder 2 to pass the wedge-the point of the tack or nail then being above the knifethe stripguide moves forward to pass its nail or tackbeyond the knife-edge. The nail, pressed down into the driver-passage beyond the knife, acts to hold the strip in place while the guidev is moved back. rlhe tack-head-forming portion of the strip, resting upon the knife, is severed by the driver, which, in its descent, strikes the head of the tack or nail in line with it. The tack or nail so severed is driven, by the further movement of the driver, into the boot or shoe. The spring o holds the headforming portion of the strip down in place in the strip-guide.

Instead of vibrating about a pivot, .the stripguide might be supported in guideways, and be reciprocated longitudinally therein.

I claiml. The combination, with the head,of the movable sleeve and attached rising and falling strip-guide, substantially as described.

2. The combination, in a tack or nail driving machine, of a strip-guide and mechanism to move it backward over the tack or nail strip, substantially as described.

3. A stationary knife and a tack or nail driver, in combination with a rising and falling strip-guide adapted to place the point of the tack or nail beyond the knife and into the driver-passage, substantially as described.

In testimonywhereof I have signed my name to this specification in\the presence of two subscribing witnesses.

CHARLES W. GLIDDEN.
