J. B. CROSBY, OF BOSTON, MASSACHUSETTS. Letters Patent No. 87,473, dated March 2, 186 9.

' IMPROVED NAILING- on PEG-GING-MACHINE.

The Schedule referred to in these Letters Patent and making P 1: 0! the same.

county of Suffolk, and State of Massachusetts, have invented an Improvement in Nailing or Pegging-Ma- I chines; and I do hereby declare that the following,

taken in connection with the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practise it.

I In that class of machines designed for making use of wire-like material, from which short lengths are cut, and driven into the soles of boots and shoes, to secure them to their vamps, it is a desideratnm to cut, before driving, each fastening, from the wire-like material, of a length proportioned to thethickness of the material where the fastening isinserterh-in order to prevent waste of the pegging ornailing-materiah to save labor in getting rid of inwardly-projecting peg or nail-ends, and to leave the inner surface of thecinner sole smooth and tree from projections. a

I accomplish this by making use of what is well known, in sole-sewing machines, as a horn, modifying it so that its salient end issolid, like an anvil-face, and arranging the horn so that it can move toward and from the presser-foonor the end of the nail or pegtube of a pegging or nailing-mechanism, and so that the thickness of the sole of aboot or shoeis calipered between the horn-end and the end of the peg or nailtube or the presser-foot, thehorn receiving and resisting the blows or thrusts necessary for the insertion of the pegs or nails, and being so arranged and connected with the mechanism whichfeeds the wire-like pegging or nailing-material, as to vary the successive feedingmovements of the wire, and cause them to supply to the cutting and driving-mechanism lengths corresponding to the varying thickness of the sole at the parts that are brought successively over the end of the horn, which is inserted in the boot or shoe, with, its anvil-face bearing against the inner surface of the inner sole.

In the drawings--- Figurelshows, inside elevation, a machine embodying my invention;

Figure 2 being a front elevation of the machine; and

Figure 3 being a partial rear elevation of the same.

a represents the standard of a nailing or peggingmachine, adapted to cut from wire-like material, pieces attached, a born, 0, so that the horn end can be moved" toward and from the end of the peg or nail-tuhe, or the presses-foot d. I

The horn is fixedon the shaft c, which is guided in bearings ff, fixed to the standard a, the lower end of the horn-shaft being stepped in a groove in the weighted lever b.

In the head g, of the pcgging or nailing-machine, are joinnalled two parallel shafts, on which are fixed two grooved wheels, h i, so that when the wire-like material, which is preferably supplied from a reel attached to the machine, is introduced into the bite of the grooved wheels, it will be fed down to the cutters when motion is given to the wheels h 'i, or either of them, in the proper direction.

On the other end of the shaft of Wheel h is pivoted an arm, j, one end of which is vibrated at the proper times and to the necessary extent, by connection with the shaft, which works the pegging or nailing-mechanism, which is not shown, as it constitutes no part of my present invention.

To the other end of arm j is pivoted a pawl, 70, which meshes into and turns a ratchet-wheel, l, fixed on the shaft of the wheelie There is also pivoted on said shafii, a shield, m, which projects over part of the ratchet-wheel teeth, so that if any part of the projection comes beneath the end of the pawl, in its stroke, the action of the pawl on the ratchet-whcel is diminished The shield on has an arm, by which, through the link a, it is connected to the weighted lever b, so that the position of the part of the shield which projects over the ratchet-teeth, with reference to the pawl, is dependent upon the position of the born with reference to the tube or presser-d.

To adjust the parts thus ,working in combination, the link it is made adjustable in length, and is also made adjustable as to the distance of its connection from the axis about which the shield turns.

- It will be seen that as the horn-end approaches the end of tube or presser (I, the shield is advanced under the pawl, thus lessening the length of the wire fed to the sole, and, as the horn-end is removed. from the creasing the feeding-movement of the wheel h, and the length of the wire supplied to the sole;

By suitable adjustments, by the means described, the feed of the wn'e n'ke material can'be made equal or slightly in excess or in diminution of such distances. I claim the combination of the vertically-moving born with the feeding-mechanism of the wire-like material, so that the feed of said material shall be in pro portion to the thickness of the stock at the points at which fastenings are to be inserted, substantially as described.

tube-end, the shield recedes under the pawl, thus in-- to the distance between the ends of the horn and tube,
