SHOE-UPPER-BEADING MACHINE.

Specification of Letters Patent.

, Application filed December 14, 1908. Serial No. 467,437.

To all whom it may concern:

Be it known that I, LOUIS WV. Gr. FLYNT, a subject of the King of England, residing at Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Shoe-Upper-Beading Machines, of which the following description,-

in connection with the accompanying drawmgs, 1s a specification, like reference characters onthe drawings indicating like parts n the several figures.

, or cord.

In the operation of upper beading as ordinarily practised the upper and lining are first sewed together wrong side out, and are then turned right side out and'their edges, when thus turned, are subjected to the action of a hammer to finish such edges. This hammer, whether it be operated by hand or by power, must necessarily have applied simultaneously to every portion of its working surface a pressure which will be sufficient to effectively form the bead, and when a seam is presented to the hammer the entire pressure thereon is applied to a greatly reduced area with the result that the stitches are liable to be ruptured and the upper in-.

jured. For this reason upper beading machines employing hammering devices, as formerly constructed, have been objectionable. Upper beading has also been performed by subjecting the edges of the upper to the acanvil, or work support, due to a rolling mo,

tion of the hammer, will not injure the seams of uppers and may be run at a high rate of speed without imposing an undue amount of initial strain upon the machine,

and will produce a superior quality of work.

the hammer and anvil, and thereby assists this manner delivers a series of applications of pressure to the work and thereby obtains all the desirable results following from the action of a hammer, but assuch pressure is applied to relatively small areas of the work in succession, the force is insufiicient to break the stitches in the seams, but is nevertheless sufficient, when applied in a series of impulses of high frequency, to bead the edge of an upper very effectively. Such a tool, together with its operating mechanism, constitutes an important feature of this invention, and I intend to'claim the same broadly. In order to give the tool or hammer the movements above defined, preferably such hammer is so constructed and arranged for operation that its working face represents a portion ofthe surface of a cone rolling on a plane surface, in this case the anvil, the hammer first approaching the anvil with its face inclined to the plane thereof, then rolling across the anvil, and finally receding therefrom with its face inclined thereto in a direction opposite to that of its inclination when it approached the anvil. These move ments are preferably imparted to the hammer by means of a crank whose pin is an gularly disposed with relation to its shaft, the hammer being carried by a sleeve surrounding the crank pin which is journaled therein. The sleeve may be provided with a projection carrying an anti-friction roller which will be guided in a slot formed in the casing inclosing the sleeve, to restrain the tendency of the hammer against rotation with the crank pin and to confine its field of operation to the face of the anvil. Such restraining means also serves to effect a suitable amount of sliding movement between in feeding the work. The cone, of which the hammer represents a portion in its movements to and from and across the anvil, has its apex at the point of intersection of the axis of the crank pin and the axis of the shaft carrying such pin, and all of such movements are produced from this point as I a center; and owing to the hammer being confined to movements in the plane of the anvil by the means described, it will be seen that the movement of any point in the face thereof will describe a curve in the surface of a sphere whose radius is equal to the distance of said point from the apex of the A tool which is arranged to be operated in cone. This construction and arrangement for imparting to the hammer its desired op eration is another very important feature of my invention.

When the hammering device having the improved characteristics as above defined, is used for upper beading, I preferably associate therewith a turning iron, also of improved construction, and, as shown, this turning iron is slidably mounted in a horn and so positioned with relation to the hammer and anvil that the operations of turning and hammering the upper may be carried on simultaneously, the feeding effect of the hammer serving to draw the work from the turning iron toward the anvil. This arrangement I also regard as a feature of importance in this invention.

In the embodiment of the invention selected for illustration the turning iron is preferably caused to operate through the instrumentality of a bell-crank lever, one arm of which is actuated by a cam, or the like, secured to the hub of a pulley having bearing on the main driving shaft which causes the hammer to operate, and a clutch is so arranged for operation with these parts as to connect said pulley to the main shaft, or todisconnect it therefrom, at will. In order to interrupt the operation of the ham mer, and to also simultaneously therewith interrupt the operation of the turning iron, suitable means, as a bell-crank lever, is so arranged relatively to the clutch actuator and the bell-crank lever which causes the turning iron to reciprocate, that upon a proper movement thereof one of its arms will actuate the clutch and its other arm will move the bell-crank lever of the turning iron to a position beyond the influence of its operating cam. This arrangement constitutes still another important feature of my invention.

The turning iron is, as herein shown, connected with its bell-crank lever by means of at spring-pressed pin which is mounted in the end of the said lever and has a tapered end to enter an aperture in the turning iron. A spring contained within a casing in the frame of the machine is suitably arranged to bear upon a pin and cause the same to enter an aperture in the arm of the bell-crank lever and engage and lock the spring-pressed pin. This also constitutes a simple and effective construction for maintaining the bell-crank lever for the turning iron in yielding engagement with its operating cam, and, furthermore, a construction which permits easy removal of the turning iron to replace it with another of a different size or shape. The cam for actuating the bell-crank lever for the turning iron is shown as acting upon a movable cam ring mounted upon ablock carrying a pin, which pin bears upon an adjusting screw carried by an arm of said lever, whereby the projection of the turning iron above the upper end of the horn may be adjusted, to compensate for wear, etc.

The main driving shaft, in the machine selected for illustration of this invent-ion, carries a worm or other gear which meshes with a similar gear 011 the hammer crank shaft, and the upper portion of the casing is formed into or provided with an oil reservoir from which the oil may be distributed by a curved tube which leads through the gear on the main shaft, into said reservoir. As the tube revolves with the gear the oil is drawn up by centrifugal force and distributed to the several gears, and to the shaft bearings.

Another important feature of my invention consists in an improved construction of anvil, for use in this and similar machines, the same being herein shown as cup-shaped and mounted to slide, adjustably, in a portion of the frame of the machine, and being also provided with cushioning means, and with a suitable device to effectits adjustment, whereby the position of the anvil relatively to the hammer may be changed to accommodate stock of varying thickness, as well as to compensate for wear.

Other important features, combinations of parts, and details of construction will be hereinafter more particularly described and claimed.

Referring now to the accompanying drawings, Figure 1 is a View in side elevation of a machine embodying this invention, with parts thereof in section. Fig. 2 is a detail view in elevation of the hammer and its operating crank, parts of the hammerearrying sleeve being broken away to show the crank pin and its bearings. Fig. 3 is a detail view, partly sectional, showing a portion of the turning iron and its driving means. Fig. 4: is a view in cross section on the dotted line a, m, Fig. 1. Fig. 5 is a detail view, showing in elevation the upper part of the machine from the direction indicated by the arrow in Fig. 1. Fig. 6 is a diagrammatic view showing the several positions assumed by the hammer and its crank during a single cycle of operations. Fig. 7 is a perspective view of the hammer and anvil, illustrating, diagrammatically, the cone of which the hammer face forms a portion, and the plane upon which it rolls.

The frame of the machine A is provided with a flange A, designed to rest upon a bench or other suitable support, and this flange as shown is arranged to support the, machine so that the main driving shaft is approximately inclined at an angle of 100 to the bench. The driving shaft B is preferably supported for rotation in the frame A upon ball bearings 12, b, and said shaft, as shown, carries at its upper end the worm gear C which meshes with a worm gear of fly wheel 6*, shown as surrounded,partly,

by a casing 6 which acts as a guard to pre vent injury to the operator.

The opposite end of the shaft E carries an angularly-disposed crank-pin G, and said crank-pin is surrounded by the sleeve F constituting a portion of the hammer F. The crank pin carries at or near its ends the cones g, g','and the sleeve of the hammer is lined with a bushing g bet-ween which and the cones are formed raceways forqthe balls g to form a ball bearing. The hammer head projects from its sleeve at an angle, as shown, the face f of the hammer presenting the same angle to a line f drawn perpendicular to the axis of the crank pin as the angle formed by the intersection of the lines 7, P, which coincide, respectively,

with the aXes of the crank shaft and crank pin, as shown in Fig. 2.

The hammer sleeve carries at a point. on the opposite side to that occupied by its head, a spindle upon which is rotatably;

mounted an antifriction roller f, to play in a slot h formed in a hood H. This hood is supported upon a bushing e which surrounds and forms a bearing for shaft E and projects from the forward end of theframe of the machine, the hood being shown as clamped to the bushing by screws h. The hood II is furthermore provided with an opening ]L2 at its under side to accommodate the projecting arm of the hammer, and is closed at its forward end by a detachable cap h It will thus be seen that the hood not only serves as a means to guide the antifriction roller f, but also as a cover to protect the bearings of the hammer. The cap [b is preferably providedwith a depending guard 72, shown as surrounding the hammer head and whose function is to protect the hands of the workman from injury by coming in contact with the hammer.

The anvil I is located, as'shown, in position to support the stock to be operated upon by the hammer. Said anvil is, preferably, cup shaped and is slidably mounted in a cylindrical portion of the frame A, located below the hood H. The rod 2' is provided at its forward end with a disk i which is located within the hollow port-ion of the anvil, and cushions i, i, are located upon opposite sides of said disk and serve to yieldingly oppose the blows of the ham mer, the cushions and disk being retained in place by an externally threaded plug i which engages an internal thread inthe ed opening in the plug i and its end engages an inclined face formed in the rod 71 to hold said rod and hence the anvil I in different positions of adjustment relatively to the face of the hammer. At one side of the anvil I is a guide k which is adjustably secured to the frame A by a set screw 71. said guide serving to assist the workman in locating the work between hammer and anvil.

Referring toFigs. 1, 3 and 4: of the drawings, it will be seen that the turning iron J is mounted for reciprocation within a horn j, the latter being suitably secured to the main casing, or, if desired, itmay be cast therewith. The turning iron is provided wit-h an aperture at'or nearits lowerend to be entered by the tapered end of a spring-pressed pin 74 mounted for movement within a casing is, which is cast with, orsecured to, an arm of a bell-crank lever K. A screw-cap j is threaded into an aperture in the horn, directly opposite the aperture in the turning iron entered by the spring-pressed pin. The bell-crank lever K is pivoted to the frame A at 7c, and has a depending arm provided with a threaded opening which is engaged by aset-screw if, under the control of a check-nut 70 The main driving shaft B has thereon a pulley M to the hub of which is secured. a cam L, herein shown as provided with four rises, and mounted to slide in suitable guideways in the frame is a block Z carrying a cam roller Z, which is arranged to be engaged and actuated by the cam L, and a pin Z fast to said block passes through an opening in the frame A, andengages a projecting end of the set screw Z2 j A casing N, formed in the frame A, contains a spiral spring N which is confined between. a cap a and a plunger 12. The plunger'n carries a pin M, which is adapted to be forced by the spring N through an aperture in the side of the casing Z0, and into engagement with the spring-pressed pin 70 in said casing, thereby to frictionally lock said pin against movement. A slidable cam n mounted below the plunger n, serves to permit the plunger and its pin to be raised. The cap a may be connected with the casing N by abayonet slot or equivalent connection, whereby the spring may be removed for repairs or the like.

The amount of projection of the turning iron J above the upper end of the horn j may be adjusted by means of the set-screw 72 and check-nut 70 in the depending arm of the bell-crank lever, to compensate for I wear. The turning iron may also be re moved and replaced with another one of different size or shape, or a worn out one may be replaced by a new one, by first sliding the cam n and raising the springpressed plunger 12- carrying the pin 02 thereby releasing the pin I0 and then re moving the screw cap j and forcing the pin 6 out of engagement with the aperture in the lower part of the turning iron. The turning iron is then lifted out of the horn and a new one inserted, the pin being first forced back until the aperture is in position to be engaged thereby, then released, and finally the cam 11 is disengaged to permit the pin a to again come into engagement with and thereby lock the pin 72 The driving pulley M is loosely mounted on the shaft B, and power is applied thereto from any suitable source by a belt M which, as shown, passes over idler pulleys rotatably mounted in a bracket projecting from the frame A. The pulley M is connected to the shaft B to rotate the same by a clutch m, herein represented as a friction clutch surrounding said shaft and free to slide thereon, but held to rotation with the shaft by a key m which is fixed in a slot in the upper end of the clutch but is freely movable in a slot through the driving shaft B. The bottom face of the clutch is provided with a disk of leather, or like material m to contact with the face of the pulley, and a spiral spring m surrounds the shaft B and is confined under tension between a collar m thereon and the clutch m, whereby the clutch may serve to transmit power from the driving pulley if to the shaft B.

A bell-crank lever O is pivoted at 0 in a slot formed within a projection from the frame A, and has an arm 0 located in position to engage a hard metal shoe 79 on the depending end of the bell-crank lever K, and an arm 0 in position to engage the end of a rod 0 slidably mounted in a recess in the shaft B, and having its opposite end connected with the key m A spring-pressed plunger 0, movable in the casing A, forces the two arms of the bell crank lever O away from the lever K and rod 0 respectively, and holds the arm 0 normally in contact with a cam 0 the same being rotatably mounted in the frame A and provided with an operating handle 0 By turning the cam 0* through its handle 0 the arm 0 of the bell-crank lever presses against the rod 0 thereby forcing said rod against the key m thus compressing the spring m and raising the clutch from contact with the pulley M; at the same time the arm 0 of the bell-crank O is forced against the lower arm of the bell-crank lever K, compressing the spring N, and removing said arm beyond the range of action of the pin Z The upper portion of the frame A is formed into an oil reservoir A which is closed by a removable cap A and the gear C carries a curved tube 0, which, as shown in Fig. 1, leads froma point near the bottom of the oil reservoir to the upper side of said gear. WVhen the gear C is rotated rapidly the oil is carried up the tube by centrifugal force, and flows through spiral grooves in the shaft E to the front shaft bearings, whereby said bearings are kept thoroughly lubricated.

lVhen the machine is at rest the cam 0 occupies a position to raise the arm 0 of the bell-crank lever 0, thereby holding the clutch out of contact with the face of the pulley, the arm 0 then contacting with the bell-crank lever K and holding the same be yond the path of movement of the pin Z To start the machine the handle 0 is raised, thereby permitting the depending arm of the bell-crank lever K to come in contact with the pin Z and the clutch member m to engage the pulley, power from the belt M then causing the shaft B to rotate the shaft E, and the hammer, through the connections described, to deliver to the work a series of applications of pressure in rapid succession, the action of the working face of the hammer being similar to that of a cone rolling on a plane, whereby the pressure delivered to the work on the anvil is caused to progress from one side of the anvil to the other, the effect of the restraint exerted upon the hammer by guiding the roller 7" in the slot h resulting in confining its lateral movements to a path corresponding to the face of the anvil, and in causing a slight slipping movement between the hammer and anvil to thereby feed the work. The same movement of the bell-crank lever O carries its arm 0 out of contact with the bell-crank lever K, to permit the actuation of the latter by the cam L through the cam ring Z and pin Z to thereby reciprocate the turning iron, the operations of turning and hammering being effected simultaneously, and the feeding action of the hammer serving to draw the work from the turning iron toward the anvil.

Referring to Fig. 7 the line f represents the axis of shaft E, and the line f the axis of the crank pin G. The plane of the face of the anvil I is represented in perspective by the ellipse 2' i 2', i and the base of the cone of which the face of the hammer forms a part in its movements toward and from the anvil is represented by the ellipse f f f f, the apex of the cone f being at the point of intersection of the lines f? and 7.

The difierent positions assumed by the hammer and its crank pin in operating through a single cycle are illustrated diagrammatically in plan in Fig. 6, the face of the hammer in this view being represented as slightly curved, beinga portion of the surface of a cone. Assuming the hammer and crank pin to be in the positions represented by solid lines, if the crank shaft is revolving from left to right the hammer moves from the position to in the direction of the arrow on the right to the position 00, gradually turns as it approaches the anvil I, and rolls across the same as the crank continues to rotate, and recedes from the anvil in the direction of the arrow on the left, with its face presented at an angle to the plane thereof which is opposite to that presented to such plane when the hammer approached the anvil, as represented at y, and, continuing to turn in the same direction, the hammer reaches theposition indicated at 2, and thence moves to the position indicated: at w again to repeat the cycle. In following the course of the hammer, as shown in thisview, it will be seen that any movements toward and from the anvil, traces an ellipse in the surface of a sphere.

While a hammer having the characteristics herein described is peculiarly fitted to effectively perform the operation known as I do not in any sense intend to belimited to such use of the invention, as there are many other operations for which it is obviously well adapted, and to which it may be applied, as will be readily suggested to those skilled in the art.
