Messine Fos.. hairline shoes Specification forming part of Letters Patent No. dllhb, dated Deceinhcr 8, 1.863.

To all whom t may concern:

Be it known that JonN HAMILTON BROWN, a .resident ot' Boston, in the county',V

of Snttolk and `State of lliiassaclnisetts, have invented a new and useful or Improved Machine for Naiiing Shoes ;A and i do hereby den elevation, Fig?. alongitndinal section, Fig.

a horizontal section, 5 a iront endelevation, and Fig. (i a rear end elevation, of it. 'Fis 7 is e horizontal section 'taken through the ratchet and pawl oi' the nail strip carrier. Fig.. 8 is a transverse and vertical section oi' the handle, it being taken in the plane ot' the rearirace oi' the stock.

Iiiyirnprcved handvmachine 'ornaiiing shoe soles not only has its shear or cutter arranged with respect to the nail-driver and nailstrip carrier substantially in manner as hereinafter described, lont has combined with the said shear or cutter' and the nail-driver a mechanism-viz., a cam and lever-which, through the downward movement of the naildriver, will he caused to force the shear forward or against the nail-strip in a manner to sever a nail therefrom, l'lho'said machine also contains a mechanism for feeding the nail-plate along as tast as may he desirable for the separation of nails from it. The inachine also contains other improvements, 'to he hereinafter explained.

In the drawings, e. denotes a tubular handle, projecting upward from a channeled.` stock, B, whose inner face is furnished with a straight groove or channel, a, leading downward from. the here of the handle. rlhe said face is also provided with a socket for the reception of a shear or. cutter, G, which slides freely in a longitudinal direction, both toward, away from, and across the channel a, and has a frictionroller, b, applied within its rear part. Against the peripheryot the said frictionroller a cam, @,fornied on a leverq D, operates, the cani serving,` to torce the shear forward during a depression of the leverL rlhis lever D has its fulcrunl 'at d, it being supported hy' the stock B. Furthermore the lever at its inner end is jointed to the lcwerend of a connecting-bar, e, whose upper end 'is jointed to a nail-driver, E, which works within the handle A and the channel a, The shank or part f of the driver is tubular from its -head gi4 to itslower end, and contains a helical spring, h, whose foot rests on a stationarybearer, i, which projects upward from the stock Bj. The spring, 'nyits reaction against the head of the bearer, serves to elevate the driver within the handle and stock, and this immediately after each downward movement of the driver.,

rthe advantages of arranging the spring wit-hin the driver, and providing such spring with a bearer to work up into the shank of the driver, while the latter may he in'theact ot being driven downward, are that'. it not only enables the driver "to he :nado ot' less diameter, hut the spring to operate with less friction than would be thecasc were the springJ coiled around thc drivere A. tubular carrier, lr, for supporting the strip G, ci copper or metal, from which the nails are to be cnt, eX tends from the inner i'aceot the stock, and-at its innerend opens' directly into the channel a. thereof. .lhe said carrier is furnished with a feed-roller, H,which projects therein in such. manner that its periphery rests against one side ot'` the nail-strip. A pressure-roller, 1 supported. by a spring, K, so operates againstthe opposite side of the nail-strip as to press the said strip in close contact with the feedy roller. a ratchet, la, is ixeduon the shaft Z ot the feed-roller, and furnished with a slideu pawl, m, which is forced up to the ratchet by a spring, n. rlhis pawl slides longitudinally within the carrier, and has a projection or cam, o, which so extends from it as to be in the path of the har c during the downward movement of the latter.1 A spring, p, fixed to the outer side of the carrier, bears against the cam o and serves to move the pawl in a direction opposite to that which it may receive -from the pressure of the bar e against its cana ately after a nail may have been severed from the strip.

nthe channel a.

taken place, the nail, bythe further descent `In operating with this machine a workman is to hold it in one hand and by its handle, he having in his other hand a hammer or a mallet. Holding the machine with the foot of stock on the part of the sole into which it may be desirable to inserta nail,he striltcswith the hammer or mallet a blow on the vtop of the nail driver, which, being driven downward within the handle and stock, will cause the shear to be advanced against the nailstrip, and to sever therefrom a nail or that part of the said strip which may project into As soon asc/this may have of the driver, will be forced downward lthrough the said channel and into the sole. In the meantime the pawl of the ratchet of the feedvwheelwill be pressed hack and will vslip 011 lthe teeth of the latter. gofthe driver by the helical spring within it, which will follow, the nailstrip and the shear During thc elevation will 'not only be forced into their normal positions by tle Vreactiony of the spring N, but. the nail-strip will be afterward advanced into the channel this `latte-r movement of thenailstrip being caused by t-hereaction of the springp against the pawl of the ratchet, the same producing a rotary movement ofthe feed-wheel, such as will canse it to advance the strip into the channel ai.'

The above-described hand-machine is an automatic one, in'so far as by a blow on the driver, by whichsuch driver may be forced downward, not onlyiwilla nail be separated from the strip and be driven out ot the machine and into a sole, but on elevation ot the driver by its spring the strip and shear will bc moved laterally, and the strip will be ad- \anced in manner as hereinbeforedescribed.

I claimy l. The improved machine as-not only having its shear or cutter arranged with respect to the nail-driver and nail-strip carrier, substantially in manner as described, but as having combined with the shear` and nail-driver a mechanism-viz., theJ lever D yand cam c, or the mechanical equivalent thereof-which, through or by the downward movement of the said driver, shall be caused to force the shear forward against the nail-strip in a manner to cause a nail by the conjoint action of the channel a and thevsaid shear to be separatedfrom the strip.

2. The improved machine as not only s'o made, but as provided with a feeding mechanism, constructed, arranged, and applied to the nail-strip carrier, substantially as and so as tobe operated by means as described.

3. The arrangement and combination of the sprin N, either with or without the auxiliary lcarrier L, with the nail carrier, the channeled stock, and the shear, made to operate with such stock, as specided.

4. ldo not claim the combination of a spring with the nail-driver for the purpose of elevating it within the handle; but I claim, in the nailing-machine, not only the arrangement of the spring within the driver, but its combination with a bearer to work within such driver, snbstantiallyas' speeied.
