1'0 (ZZZ whom it may concern.-

Be it known that I, JOHN Enms CUTLAN, a subject of the Queen of Great Britain, residing at 46 Market Square, \Vellingborough, in the county of Northampton, England, architect and surveyor, have invented certain new and useful Improvcmentsin Machines for Driving livets or Nails into the Soles of Boots or Shoes, (for which I have received Letters Patent in Great Britain, No. 7,893, dated May 19, 1884,) of which the following is a specification.

This invention relates to improvements in machines for driving rivets or nails into the soles of boots or shoes, whereby I am enabled to quickly and regularly drive nails or rivets into either the inner sole or outer sole in the mamifactnre of boots or shoes.

In order the better to explain my invention audthe manner of carrying thesameinto practice, I will proceed to describe the same with reference to the accompanying drawings.

Figure 1 shows a side elevation of my improved macbinc. Fig. 2 shows a front view elevation. Fig. 3 shows enlarged detail view of the gripping device for locking the support or rest. Fig. 4 shows enlarged view, in elevation, ofthe nail feeding and driving apparatus. Fig. 5 is a transverse section of the nail-reservoir. Fig. 6 is a plan,partlyin seetion,of the nail'reservoi r and slide for regulating the supply of nails or rivets.

Similar letters of reference indicate corresponding parts throughout, and for brevity I shall hereinafter refer to both nails and rivets as nails, and similarly to both boots and shoes as boots.

()nthc standard: is mounted the fly-wheel y, as shown, driven by means of a treadle, .r, and eonuectingrod in, the trcadlc as always be ing brought into position ready to start the machine, as shown in Fig. 2, by means of the spring 90.

On the shaft of the fly-wheel g the toothed wheel 9 is firmly sccured,and this again gears with and drives the second toothed wheel, v, on the main shaft 1;, from which shaft'u the whole of the parts ofthe mechanism are driven or actuated as follows: The plunger a (sliding in bracketarms 2' J on the standard 2 and carrying the punch or driver a',fiXed therein) has rcci n'ocatory upward and downward mo tion imparted thereto by means of the connectiug rod or link I), on the crank-pin c, on the outside of the double cam o, fixed on the shaft 1;. This revolvingcam cgivcs motion to the slide-bar d by means ofthe connecting arm c, on which is mounted theproiection c,which rides against and is actuated by the doublecam surface 0. (See Fig. 4.)

To the upper part of the plunger 11, and free to turn thereon, is mounted the armf, which again is connected by mcansof the forked rod f to the nail-rcservoinf, to which it is secured on centers/"K Fig. 5 shows the nail reservoir fflhaving two compartments, f and f, (for two different lengths of nails) each compartment having a slot, f and f", respectively, in the bottom thereof wide enough to allow only the nailshanks to drop through, and in Fig. 6 the nail feeding device is shown, this being a plate. f]. having a slot, g',(si milar to the slots and f.) down which the nails are fed from one of the said slotsf andf", either of which can be brought opposite the slot g by the catch g, while the nails are prevented from coming out of the slot out of use by the stop or catch 1/, held in position by thesprings y.

The slide-bar d has fixed thereon the slotted plate or slide it, (advantageously formed in two parts, as shown in Fig. 6,) having the feedslot i, which, by the action of the cam 0, permits one nail at a time to pass from the groove or slot y into the tube or conductor 0, down which it falls into the holoj, immediately under the punch or driver a. This hole is formed in the spring catches I; and I, which are mounted on axes It" and Z, and arev forced to Openoutward by the driver a coming down, but normally kept closed together by the spring M, as shown in Fig. 4, the fecd'tube o and the parts I. andl bcingdivided and made so as to open together on hinges o o' for convcniencc in cl auing out or repairs.

On the shaft c, Fig. l, is also mounted an eccentric, p,whicb,by means of the connectingrod 1) and arm q, Fig. 2, causes the partial revolution of the axis a, having on the end thereof the toothed wheel 11, which gears with and revolves the feed-regulating wheel 8, mounted on the support a, which support is also adjustable by means of the regulating screw s.

On the shaft 1) is also mounted a second eccentric, it, (see Fig. 3,) with a connecting-rod, t attached to a crank-arm, t, (with a spring, 1'. inserted and combined therewith,) for gripping and firmly holding the upright pin t, which travels through its otherend, I, this pin it at its lower end resting against thelevcrbar I, which forms the support for the rest a", upon which the work is laid.

The operation of the machine is as follows: Referring to Fig. 1, the work is placed on the rest a by depressing the lever-bar or support 1.", which is t'ulcrumed at f, and at its other end, t, presses up the rod t and springthereon, as by thus depressing the lever arm the rest a drops down therewith and leaves space to lay the soleor other work on the rest. The lever-arm I." is then released and the reaction of the spring on the rod 1 presses the arm i" up again and with it the rest a. The machine is now put in motion,and at each revolution the plunger a is moved up and down. This also, by means of the forked arm f, rocks the nailreservoirf (which is hinged to the plate g so as to cause some of the nail-shanks to drop through the slot] orf, and thence pass into the slotgin plateg. The slide it is then moved across by the slide-bar (l, actuated by the cam c, and the slot i in the slide h, Fig. 6, as it is moved across, allows only one nail to pass down and upon the bottom of the slot t, coming over slot 5 This nail then drops down the tube or passage 0 and falls with its point downward into the hole j, directly under the driver a. Atthis moment, before the driver comes down onto the nail, the ecccntrict, Fig. 3, forces down the arm 1 and firmly grips the upright rod t at the point t and holds the same rigidly. Thus the lower end thereof offers a firm resistance to thelever-armt, which therefore makes an immovabtcsupport for the restc' The driver a now comes down onto the nailhead and forces said nail through the loose jaws k and I, which open outward accordingly, and the nail is driven into the material lying on the now immovable rest a. As soon as the driver a has reached its lowest point the eccentric f and its connecti ns release the grip on the rod 1, and the teed-wheel s is then immediately caused to act by the co centric p, which is in such a position as to be just then commencing to lift; the eceentricconnectingrod 1), by which it raises the arm havingaspring-pawl at the end thereof, which pawl,when the arm (I is forced down,runs over the teeth a on the end of axis 1/, (see Fig. 1,) and this pawl engages with the teeth 11* on the axis 14, and so partially revolves the said axis )1 and toothed wheel 1: on the end thereof, and thislatter again gives a partial revolution to the wheel s, against the milled or toothed edge of which the work is pressed, which is thus fed forward aftereaeh nail has been driven in, the distance apart at which it is desired to d rive the nails being regulated more or less by altering the position of the lower end of the rod 1) in the slot (1 of the arm (1, (see Fig. 2, and thus causes more or less travel of the arm q, and consequently imparting more or less fcedanotion to the wheel 21. By turning the screw s", Fig. 1, round the supports and feed regulating wheel s are drawn away from or moved toward the rest (6 and opening j, through which the nails are driven, and so regulates the distance from the edge ofthe material at which it is desired to drive in the nails.

If desired, an indicator or counter, 'lt, may be mounted, as shown in Fig. 1, the main axis v passing through the top thereof, and so actir ating the train of wheels of the counter, and thus showing the number of nails used, as at each revolution of the axis 0 a nail is fed down and driven into the work.

Having thusdescribed my invention, I claim as new and desire to secure by Letters Patent 1. In a boot-nail driving machine, the colnbination, with the plate 9, having the slot 1 and an aperture, 0, of the slide h, having the slot at an angle totheslot g, and also having the slot transversely to the slot y, substantially as set forth.

2. Ina boot-nail-driving machine, the combination, with the slide it, having the sloti therein tin-supplying one nail at a time under the nail driver, ofthe cam c, the plunger 1, the nail-driver a, the rocking nail-reservoir f, and the forked arm f, the said plungerarocking the naitreservoir by means of said forked arm f substantially as set forth.

In a boot nail-driving machine, the conr bination, with a cam,c, nail-reservoirf nailfeed-regulating slide h, and slotted plate g, of a tube, 0, plunger a, carrying the nail-driver a at its lower end and having the forked arm I' connected to its upper end for rocking the nail'reservoir, and the loose jaws k and I, kept closed by spring in, substantially as set forth.

4. A bootnail driving machine worked with the main actuating-axis '0, having the two eccentrics fand p and the double cam c thereon, a nail-driver actuated from the occentric t, and the regulating-wheel operated with the cccentricp, and a naitfeeding device operated by the doublecam c, substantially as set forth.

5. A boot-nail driving machine constructed with a gripping device consisting of an arm, I, actuated by eccentriet through the rod 1, having spring I inserted in the slotted end, an upright rod, 1, gripped at I", and the lever-arm t", which supports the rest at the moment the driver (1. driving in the. nail, substantially as set forth.
