MACHINE FOR DRIVING FASTENINGS,

SPECIFICATION forming part of Letters Patent No.` 248,553, dated October 18, 1881.

Application filed September 15, 18H1. (No model.)

To all whom it may concern:

Be it known that l', JOHN O. BOND, of the city of Lynn, in the county of Essex and State of Massachusetts, have invented a certain new and useful Improvement in Machines for Driving Fastenings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming a part of this specification, in explaining its nature, in which the figure of the drawing is a perspective view of a machine employing my invention.

My invention consists in the employment of a yielding gage or guide, in connection with a device for driving fastenings, and a jack for presenting the boot or shoe to said'device.

Heretofore in peggin g and nailing machines it has been common to employ' in connection with said devices a gage which was made horizontally adjustable in relation to the nozzle of the pegging or nailing machine by means of a set-screw; but said gages, so far as I am aware, were not provided with any means whereby they were made automatically adjustable upon the contact of the last, carried upon the jack, therewith, the method of adjustment being to loosen the set screw or nut, move the gage to the desired place or position, and then fasten it there until it became desirable to relocate it.

For theelass of work with which I propose to use my improvement it is practically of no greatimportance 'whether or not the fastenings are located at auniform distance from the edge ofthe last or insole. Therefore it is not material that the gage be fixed. For ordinary pegging or nailing machines this is not so, because it is very essential that the fastenings have a uniform distance from the edge ofthe last or insole.

The special class of work for which I use this invention is the lasting of the uppers of boots and shoes, and the gage is used,in connection with the other devices named, not so much for the purpose of gaging the distance from the edge of the insole or last at which the fastenings shall be driven as to steady the work as it is being fed to the fasteningdriving devices.

In the drawing the machine for driving fastenings represented is that shown in the various patents granted George W. Copeland, Ilrastus Woodward, and Matthias Brock for driving` tacks from a flexible carrying-strip, and I make no claim therefor; neither do I make any claim to the jack shown in the drawing, as thesame, or material parts thereof, is to be made the subject-matter of a separate invention by anotherinventor. Itis sufficient to state that thejack has necessary movements for presenting the last to the taelring-maehine.

A represents the nozzle of the fasteningdriving machine, through which the fastenin gs are driven.

B represents the jack; C, the last, having an upper mounted thereon and supported by the jack.

D is the yielding gage. Preferably itis made narrow in width and of some considerable extent vertically, as represented. It is carried at the end of the horizontal arm d, which slides in suitable ways in the frame of the machine, and has the slots d', in which are the guide-pins or fastening-screws, which secure it in place and govern the extent of the movement. It also has, projecting downwardly, a spring, d2, which is fastened to it, and whose end d3 bears against the frame of the machine.A Of course the operation of this spring is to keep the gage substantially in the position shown in the figure of the drawingthat is, in the position nearest the nozzle and farthest ont from the frame of the machinetheset-screws acting as stops to prevent itfrom being thrown farther out. From this extreme position, upon the contact of the edge of the last or the insole thereon therewith, it is moved inwardly according as the emergency of the lasting operation may require. For instance; if the toe and side portions of the upper are being lasted, it is probable that the gage will not be moved back very far from its original position. Upon reaching the shank, however, it will become necessary to tip the last more, in order to tack the edge of the upper to the insole, and in so doing the gage will be forced backalittlemore. Ofcoursethesemovements are not always as above stated, and depend very largely upon the shape of the last.

In lieu of the spring d2 shown and described, any other suitable spring may be employed.

The position of the stop restricting the outward movements of the gage may be varied, so that the gage may be set to adistance nearer or more remote from the nozzle, it desired.

The gage may be made in one piece with its inwardly-projecting arm or separate therefrom without departing from the spirit of the invention.

The advantages of this invention have been described incidentally in connection with that of the construction. Y

Having thus fully described my invention, I claim and desire tosecure by Letters Patent of the United States- 1. 1n a machine for driving fastenings, the combination of the nozzle ot the fasteningdriving device, through which the fastenings are driven, with a yielding gage or guide, D,

having the position in relation to the nozzle 15 specitied, and adapted to operate substantially as set forth.

2. The combination ot' a nozzle of a fastening-driving device, through which fastenings are driven, a yielding gage or guide located 2o in relation to the nozzle as specified, and a jack and last for presenting the work to the instelling-driving device, all adapted to co-operate substantially as specitied.

JOHN O. BOND.
