IMPROVEMENT IN SOLE TRIMMING AND BURNISHING MACHINES.

Specification forming part of Letters Patent-No. 130,212, dated August 6, 1872..

To all lwhom it may concern:

Beit known that I, OHARLEs W. GLIDDEN, of Lynn, in the county of Essex and State of Massachusetts, haveinvented certain Improvements in Trimming and Burnishing the Edges of the Soles of Boots and Shoes 5 and I do hereby declare that the following, taken in connection with the drawing which accompanies and forms part of this specication, is a description of my invention sufiicient to enable those skilled in the art. to practice it.

The invention relates to the construction or organization of a machine'for trimming the edges of soles of boots and shoes, and to that class of such machines in which the shoe being mounted upon a suitable jack has its edge presented to the trimming device, the shoe having a reciprocating oblong and semi-rotative movement, to bring the entire length of each side from heel to toe, and the entire pesuccession, and by a continuous movement of the shoe, to the action of the trimming tool or tools.

- In my construction I use an oblong gear-1 plate, the line of teeth of which has a curved form corresponding to the general form in outline of a sole, which gear-plate I drive or feed by a pinion placed above it on a shaft rotating a shaft, which is supported upon a link connected to avertical slide, and said slide being pressed up by a weighted lever, so thatthe link may partake of or conform to the irregular movement of the gear-plate, and said plate shall be held up to the pinion and kept in engagement therewith by the upward pressure upon the link, the plate having in its rear face a groove near its edge and equidistant therefrom, into which a stud-pin enters, said pin and groove maintaining the proper relation between the gear-plate and the pinion, and the weighted lever rendering thc movements of the plate uniform and preventing strain upon the pin and groove-walls. The gear-plate shaft extends from the center of the plate, but the shoe is jacked upon a pin (extending from an arm of said shaft) which is in line with the heel or the heel part of the shank, as the jack-- pin must pass lthrough the open or leg part of the boot or shoe, and, the shoe being thus jacked, its movement corresponds to the movement of the gear-plato. To the sole-edge of the shoe thus jacked and moved are applied the trimming devices, and the guiding and guarding devices, by which the depth of cut and the uniformity of edge with relation to the upper are insured.

For carrying these devices I use a compound arm, to one member of which, swinging on a horizontal-pin, I pivot a vertical pin carrying a horizontal bearing, upon which are pivoted two other members, one of which carries guides for keeping the cutters in position to trim the edge and rand, and the other of which carries the edge cutter or cutters, both of the latter arms swinging or yielding horizontally, so that guides and cutters can follow the curvatures of the face of the sole, and both swinging or yielding vertically to follow the edge curvatures of the sole or the upper adjacent thereto, and the edge-cutter and the guides and randcutter also having provision for being relatively set for adjusting the angle of the face of the edge to be formed.

For the arms carrying the guides and cutters, arms may be substituted carrying guiding and edge-burnishing wheels; and the invention consists primarily in the combination of the gear-plate made and mounted as de.- f

scribed, and carrying a shaft to which is fixed the shoe-holding jack, of compound arms, carrying guiding and trimming or burnishin g devices so arranged that the said devices have irregular movements conforming to{the movements of the edge to be trimmed or burnished, and are automatically held to such edge to effect said trimming or burnishing.

The invention also embraces other features of construction relating to'the arrangement of the guides and cutters, and of the burnishingwheels and guides, the construction of the jack, &c.

The drawing shows a machine and mechanism embodying my invention.

A shows the machine in side elevation. B is a plan of the machine. C is a front elevation of it.

a denotes a post, upon which the various parts of the machine are supported. At the front of this post is a vertical slide, b, moving on a guide-rail, c, and having jointed to its front a link, d, to the upper end of which link is pivoted the gear-plate e. ,This plate is made with the oblong sole-shaped gear f, and has in its rear side the correspondin gly-shaped groove g, into which extends the stationary pin h projectin g from the plate t' of the post. The pivotpin j extends from about the center of the gearf, and has at its front end an arm, k, from which the jack-pin l extends, said jack having secured upon it the shoe m, the edge of which is to be trimmed or burnished. Over the gearplate c is a gear-pinion, a, xed on a drivingshaft, o, rotating in stationary bearings at the top of the post, the rotation of the gear imparting the longitudinal and rotative move- Inents to the gear-plate to cause the jack to be similarly moved in order to present the whole length of sole-edge to the action of the trimming or burnishin g mechanism. The slide b is jointed by a link to the front end of a lever, p, pivoted to the post, and having its rear end weighted, the stress of the weight keeping the gear-plate in position or up to the gearpinion, so that the gear-plate and jack may be properly guided by the groove g and pin 71 without tendency of the pin to bind in the groove, or of the jack vto sag by its weight. rEhe jack to which the shoe is secured is peculiar, and is shown in detail at D, E, F, and G. Said jack has two plates, q i, ,(which may be called heel and sole plates,) the plate q being jointedto an arm, s, extending from a tubular support, t, and the plate l' from a similar arm, a, extending from the support t. Said support t is pivoted to a bearing, c, by a pin, w, and sliding in the support is a rod, x, having pins extending from it through slots in the support t, upon which pins are friction-rolls y rolling in guide-grooves c in the bearing t, said slots being eccentric to the pivotal pin fw. The outer end of the slide-rod .r is pivoted to the adjacent ends of the two plates q i, as seen at D and G, and when the support and sliderod are in line with the pin l the two plates are in -line, as seen at D, while when said support and rod are swung around to a right-angular position to said line the movemento'f'the rolls yin the eccentric slots z draws in the sli\- rod x and brings the plates to the relative auf guiar position seen at G. To the front of the sole-plate r an upper stretcher, c2, is pivoted, said stretcher having a roll, b2, traveling on the arm u, and when the plates are brought into angular position this stretcher is thrown toward the plate r, as seen at G, while by straightening the plates it is thrown from the plate 1", as seen at D. When the shoe is to be jacked the support and slide are swung around until the plates assume the position seen at G, and the shoe can then be easily drawn over the plates, and, when so drawn over, the support and slide are thrown back to bring the plates into the position seen at D, and the plates, in straightening, will expand or stretch against the shoe-upper and directly against the sole, so that, by the combined movement of the plates and stretcher, the shoe will be rigidly and immovably fastened upon the jack. When the slide u comes into line with the pin l a spring-bolt, c2, iiies into the notches d'2 and locks the slide-rod support t, bearing u, and plates r q in relative immovable position. The trimming or burnishin g mechanism is supported upon an arm, f2, mounted on a horizontal bolt or pin, g2, extending through the end of a stationary arm, h2, which projects from the top of the post a. To vary and adjust the angle of presentation of the said mechanism the arm f2 is made capable of vertical movement upon the bolt g2, and the sleeve by which it is mounted upon the bolt bears, at its inner end, against a lever, 112, also mounted on said bolt, the sleeve being tightened and held against the lever by suitable nuts upon the bolt, between one of which and the adjacent end of the sleeve is placed a suitable washer. The lever extends toward the post a, and carries at its inner end a spring-latch, k2, which enters a notch, Z2, in a plate, m2, which plate may be made adjustable in position by means of a nut and screw, n2, and a slot, 02. The nut p2 being loosened, the trimming or burnishing mechanism is set or adjusted to the desirable presentation thereof with reference to the soleedge to be acted upon, (the lever-latch k2 being in its notch,) and the nut is then tightened. This being effected, the mechanism may be raised from the shoe or from working position to apply or remove a shoe by drawing out the latch k2 and lifting the lever if", the 1ever i2 and arm f2 swinging as one. The burnishing or trimming mechanism is attached to the arm f 2 by means of a pin, q2, which extends down from a horizontal sleeve or bearing, r2, and through a vertical bearing, s2, at the end of the arm f2, the pin g2 and its bearing T2 swiveling in the bearing s2, and being tightened by a screw and nut, t2. a2 denotes the edge-trimming cutter fixed upon the arm ft2, the shank of which arm is formed as a cylindrical pin or shaft, j, journaled in the bearing r2, in which it may be confined and more or less tightened by a screw, m2. For convenience the arm ma-y be provided with a series of cutters, u2, extending from a ring, y2, fastened upon the arm by a nut, z2. rI he cutter stands horizontally, or approximately so, and its cutting-edge extends over the edge to be trimmed from outside ofthe sole, and the depth of cut is gaged by a guide-foot, a3. This foot is, at the bottom of a shank, b3, connected to an arm, c3, which arm extends from the cutter-arm c2, the arm c3 being preferably connected with the arm u2 by means of a sleeve, d3, fitting upon the pin jz, upon which it is fastened in position by a screw, e3, which screw permits the arm to be adjusted in angular position with reference to the cutter-arm c2. The gage-foot rests upon the upper at the seam, and thereby gages the depth of cut of the edge-trimming knife from said upper, and, to trim to amore or less projecting edge, the foot is made adjustable in height, its shank b3 passing through an arm, f3, extending from a pin, g3, which pin g3 passes through a vertical sleeve, h3, at the end of the arm c3, and is pressed down by a spring, i3.

is provided with two guide-rollers, k3, at the a sleeve, f4, that carries a grooved pulley, g4,

The pivot q2 enables the guide and cutters to follow the lateral irregularities of the sole, and the pivot g2 enables them to follow the peripheral irregularities thereof, and to keep the cutters and guide'against the edge the pin g3 bottom of two projections, Z3, from a plate, m3, which plate m3 has ears n3, by which it is hung to pivots o3, extending from opposite ends of the pin g3. A tail-piece, p3, of the plate has a spring, g3, that bears against the bearing h3, and when the parts are in position to operate the gage presses upon the inner side of the sole and the rolls upon the outer side thereof, the rol ler-frame swivelin g in conformity to the irregular or curved form of the sole-face, but keeping the gage at all times in position.

In connection with the gage and edge-cutter a rand-cutter, r3, may be employed, said cutter or cutter-head being xed to or forming the bottom of the pin g3. The cutter-head may beformed with a shoulder that rests upon the sole-edge or upon the edge-cutter, and has a vertical lip, s3, on the inner face of which lip is the blade r3 that trims the rand, the blade being presented to the face of the rand toward the upper. .In the burnisher mechanism the arm e3 has extending through it a shaft, carrying at its outer end a bevel-gear, a4, meshing into and driving a bevel-gear, b4, on a shaft, c4, which shaft carries another bevel-gear, d, meshing into and driving a beve gear, e4, on

which, by a band, h4, is connected to a pulley, i4, on a shaft, 164, carrying a burnisher-roll, Z4, which roll is made with a cylindrical or other shaped peripheral surface, m4, to run in contact with the outer edge of the sole, and two lips or flanges, n4 o, that embrace the edge and burnish the top and bottom of the sole irnmediately adjacent to the edge, the flange o4 being preferably made as a ring sliding upon the shaft, and pressed up against the sole by the stress of a spring, p4. The shaft of the roll n4 is journaled in a frame, g4, that swivels horizontally on the shaft, so that the roll and its flan ges accommodate themselves to the curves as well as to the varying thickness ofthe sole; and to guide the roll or keep it properly presented the frame g4 is provided with two friction-rolls, r4, that bear upon the outer face of the sole, (one on each side of the point of aetion of the roll m4,) these rolls turning on pins extending up from a slide-plate, 84, that slides in the frame and is pressed up to the roll by the stress of a spring, t4. When the frame is pressed down to hold the burnisher to the soleedge the pressure upon the gears would tend to make them bind; to obviate which I use friction-rolls a4, (turning on pins extending from the frame,) which bear upward against a disk, fw", and, rolling against the same, enable the frame to freely swivel without affecting the gear-train.

By means of a machine having the general organization set forth, and with a trimming and burnishing mechanism substantially like those described, the edges of the soles of boots and shoes may be rapidly, evenly, and effectively trimmed and iinished.

Heretofore it has been always customary, in

machine trimming or burnishing the heels of boots or shoes, to present the boot or shoe to the trimming or burnishing mechanism upon a last; but in this invention the last is entirely dispensedwith so far as relates to these operations, the stretcher-plates or jack-plates holding the shoe as rmly as it could be held by a last, and its application and removal to and from the jack being effected very quickly and with the utmost ease.

In the series of cutters @L2 the cutting-edge may be made so as to form diiferent bevels and to gage the action of the rand-cutter as the foxing of the toe of a shoe meets the cutter. I employ a device, represented at J, in which, at the side of the cutter r3, is a spring foot or gage, 004, that rides upon the upper. At each side of this foot is an auxiliary foot, 1/4 a, the shank of which slides in al box, a, and is jointed to a conn eetor, bs, said connector being pivoted at c6, and throwing down either foot when the other one is pressed up. Normally, the position of the two feet 1/4 a4 is just above the point of the gage-foot x4; but when the foot in advance strikes the foxin g the other foot is'pressed down, thereby raising the gage x4 and the cutter before they reach the foxin g.
