To ALL To WHOMIT MAY concnam' Be it known that I, THOMAS CABOURG,oi` Paris, in the Empire of France, have invented a new and improved lBoot-Soling Machine; and I do hereby declare that the following is a full and exact description thereof, reference being made to the accompanying drawings, and to the letters of reference marked thereon.

The object of my invention consists in the construction of a machine which will form a'thread upon a continuous length of brass wire, and at the same time cause itto penetrate by screwing in any portion of leather or such like material, so as to unite them in one. For instance, if it he applied to unite the upper leather'or vamp of a b'ootor shoe with the sole orV soles, it is only requisite to present the materials to` be united to the tapped end of the wire, and the rotation caused by the machine will enable it to penetrate, without the necessity ofhaving any hole made in the leather to bejoined.

When suicient length is introduced, it is, by .means of mechanism, cut close to the edge ofthe material. The machine by which this is effected consists of a` pulley, `with a large groove, upon which the wire to be .tapped is wound. v h l This wire, when uncoiled from the pulley, passes through ahollow'axle, which gives it a motion'of rotation, l in a plane perpendicular to the direction of its course when unwound from the pulley. Y' Y h Hence, it has imparted to it a progressive spiral motion, and in this way enters the tapping-plate, andhasthe thread cut upon it.

From this plate it passes through a guide, and then enters into the leather or materials to be united, and, after'penetrating them to a suiiicient depth, it is cut by a painot' knives, which, by means of the motion ofthe wire, and the disposition of the knives, give it'an oblique cut, so as to form a sharp point upon the succeeding part o'i` the wire, which enables it to enter more easily `the material, when, in its turn, it is brought into position. The knives are brought into action by means of a series of levers and treadle, or by any 'other well-known means.

The machine is placed upon a frame, and may be worked by hand or othermotive-power. vIn using my machine, it is only requisite to apply lightly the leather, or 'other material to be united, to the end of the tapped wire, it not being necessary to`rs't pierce a hole, as is generally done. jFigure 1 represents an end vewof my machine.

Figure 2 being a side elevation, and Figure 3 a plan. y Y My machine is composed of a pulley, A, on which the wire to be tapped is wound, and is indicated by the dotted lines in v'fig'. 2. The axle of this pulley iss'upported "in bearings in the rectangular frame B, which is supported at one end by the upright, 0,' and at the other by the hollow axleD, which turnsin thel upright, E, which is itself fixed on a stand, firmly bolted to the main foundation-plato.

All `the mechanism connected with the knives is fixed tothe plate G, and is composed of a lever, K, one extremity of which terminates in a. hook, in connection with the rod P, the Vend of which is connected with the treadlo Q. The other extremity ofthe lever K-is formed with a. sort otvhook or fork, which embraces a stud, a, fixed in the vertical shaft L, which slides in the guides M N.

On this shaft are two lugs or ears I1 b, to which are attached the extremities of the rods T fll.l The other ends of these rods are connected with the curved levers U, whose upper extremities are terminated 'in a fork, c, for the'purposeof actuating the studs it', which are fixed in the shanks of the knives ff. Y

The whole of the series of levers is fixed to the plate G; which isviirmly bolted to the two pieces gg, which are cast with the support E.

The wire, on leaving the pulley A, traverses the length of the hollow axle D, and at its exit has the thread out o n it by the tapping-plate I, which is regulatedby the screw d.

After the tapped wire has left the plate I, it passes through a guide, e, and between the two edges of the knivesff, then, when wished, by acting or. thc end of the lever K .with the foot by means of the/treadle Q, the

knives are actuated simultaneously, and the edges having the form of an inverted V, they perform a. double out,

one to theA right against the-left to cut oi the tapped wire, andthe other oblique, for the purpose of making a point to the end ofthe wire. l i

These knives have their shanks formed square 4in section withintho guides L L', to prevent them from turninground when'acted on by the levers U U. The distance or movement of the knives is regulated by means of the screw N, fixed to the plate Gr. i i

The levers are coupled, soas to act simultaneously, by the rods T T, connected with the vertical shaft L.

The machine is put in motion by means of the handle' g, fixed on the axle of the toothed wheel R, which gears into the pinion S, which gives motion to the hollow axle D, and consequently the frame B, and the pulley A, on which iswound the wire.

During this rotation, the wire passing through the tapping-plate I, has'a thread on it, then, when it has i penetrated a'suficient depth into the leather or other material to be united, it is out, as has been already shovrn, by the application of force to the treadle Q.

The pressure is communicated to the-rod P,to the lever K, and consequently tothe rods T T, which acting on the curved arms U U, which communicate the motion te the knives, the latter are brought back to their nor'- mal condition by Ameans of thespring V, fixed on the frame of the machine. l

The actionl of these levers will be fully seen, referenceoeing had to fig, 1 of the drawings. rlhis machine can be constructed of any size, and actuated by steam, manual, or any convenient power.l

Figure 4 is a toothed lever, whichI connect to theframe, for the purpose cf resting the support A, Figure 5, to the boot or shoe during the operation of screwing ou the soles. Y Having now described my invention,*and how the same is or may be carried into effect, what I claim, and desire to secure by Letters Patent, isi l i A 1. The, construction and use of tho pulley A, on which is wound the wire to be tapped, substantially as herein described. j n i 2. The construction ofthe tapping-plate, substantially as described. y

3. Theconstruction, disposition, and simultaneous action ofthe knives, substantially as described, and more fully shown in the drawings. i V T. CABOURG.
