PORTABLE POWER CHANNEL-FLAP LAYER.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed September 12, 1906. Serial No. 534,247.

To all whom "it may concern:

Be it known that I, WILLIAM H. Hoornn, a citizen of the United States, and a resident of Lynn, in the I county of Essex and State. of Massachusetts, have invented an Improvement in Portable Power Channel- Flap Layers. of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to machines known in the art as channel flap layers, adapted to pressinto place and smooth out the channel flap of boot and shoe soles after the attachment of the sole to the upper by stitches or other fastenings applied in the channel of the sole has been completed. In the manufacture of boots and shoes after said stitches or other fastenings have been inserted in thechannel formed in the out sole, the channel flap or lip is cemented and then relaid or turned down into its original position to cover and protect said fastenings. In the operation of nearly all channeling machines, however, as at present constructed, the channeling tool usually commences its channel cutting or forming movement on and at the right side of the shank portion of the sole or at the loft viewing the tread face thereof and works forward, following the edge of the sole to and around the toe, and back to a corresponding point on the opposite side of the shank, the flap thus being turned up and always laid 'back in one direction.

The operation of the channeling tool, however, also causes the flap to be moved slightly longitudinally of the 5.110, pushing its outer edge slightly forward or in rear of the position normally occupied in the channel, or, to express it differently, the flap is turned up not only transversely or at right angles to the face of the sole, but somewhat obliquely thereto and in the direction in which the channel tool operates, or in cases where the latter is fixed and the shoe moved, opposite to the direction of such movement. The same results are also produced where a flap or lip turning device is used for opening the channel, either in conjunction with the channeling tool or independently and furthermore the flap thus cut or turned is more or less wrinkled or puckered, and, as the sole is set or tempered preparatory to cutting the wrinkles thus formed in the flap are set by the drying of the sole and are difficult to remove. When the flap is relaid, after the fastenings have been placed in the channel, if the work is done by a machine the sole is presented to the action of a grooved roller or other tool, the ribs or working faces of which act to turn down the cemented channel flap into the channel on one side of the shoe in the opposite direction to that in which it was turned up in the action of the channel cutting or flap turning tool, thereby smoothing out the wrinkles therein. On the other side of the sole, however, the flaplaying tools while turning down the flap into the channel either do not relay it into its original position, or turn it down oppositely to the direction in which it is turned up, that is to say, oppositely to the oblique direction referred to. On this side of the sole therefore the flap is relaid with more or less wrinkling or puckering, and particularly also about the toe of the sole, and increasing or intensifying the wrinkles on said side or already in the flap. In order to efficiently relay this flap it should be turned down not only upon one side but all around the sole uniformly and oppositely to the oblique direction in which it was turned up, so that each and every part of theflap will be returned to its normal place or position in the sole, and the wrinkles put into it in channeling or turning the flap up smoothed out or removed during the flap laying process.

One of the objects of my invention is to provide a flap l laying device which, commencing its operations at a point where the channel tool ceases to act or where the channel ends at the left side of the shank or heel portion of the sole, viewing the bottom thereof, will turn down the channel flap all the way around to the beginning of the channel at the opposite side of the shank in the reverse direction to that in which it was turned up. Furthermore, machines previously constructed have been provided with flap laying or turning devices mounted to rotate about a fixed support, and the shoe has usually been presented by hand to bring it in flap laying relation to said flap turning device. I have discovered, however, that the channel flap is more ad vantageously and efficiently turned down in the oblique directions referred to and relaid into its normal sole position by mounting the shoe upon a fixed support while the flap laying devices are brought into any desired operative relation with the sole of said shoe and moved progressively thereover.

Another feature of my invention therefore relates to a portable power means for supporting and operating the channel flap layers while permitting them to be moved freely over the sole and at any desired angle relative thereto.

All of the above, however, with other objects and features of my invention will be best understood and appreciated from the following description when taken in connection with the accompanying drawings of a preferred embodiment of my invention, selected for the purposes of illustration, the scope of said invention being more particularly pointed out in the appended claims. V

Referring to the drawings: Figure 1 is an elevation of the right side of an organized machine embodying one form of my invention and selected for purposes of illustration only; Fig. 2 is a detail in front elevation of the portable power channel flap layer used in connection therewith; Fig. 3, a plan view thereof; Fig. 4, a horizontal section on the line 4-4, Fig. 2; and Fig. 5, an enlarged detail thereof to show the construction and arrangement of the rollers.

Referring now to Fig. 1, A represents a sole pressing machine which may be of any desired shape or c'on struction but in the particular embodiment of my invention hertin selected for illustration is preferably substantially the same as shown in Letters Patent to me No. 684,239, dated October 8, .1901, to which reference may be made if desired. This machine is of the sole beating out type, having a jack, J, on which the shoe is supported and which carries it into operative relation with the molds by which the shoe sole is laid or leveled. Above this machine (see Fig. 1) is the portable power channel flap layer B which, in the present embodiment of my invention, comprises a suitable movable carrier suspended by hangers 1 from an overhead support, provided with channel flap rollers 2 and 3 supported thereby in convenient operative relation to the normally stationary jack of the beating out machine.

It will be understood by those skilled in the art that with channel flap laying machines as at present constructed the shoe is presented by hand to whatever type of flap laying devices are employed, the latter usually being mounted upon a rotary shaft journaled in a fixed support. If, however, the shoe is mounted on a fixed support and the flap layers made movable relatively thereto, each shoe must be mounted upon the jack to be operated upon and removed at the conclusion of the flap laying operation, so that more or less time would be lost in what is termed jacking and un- 'ackin the shoes. To prevent such a loss of time and also that required to move shoes from the usual flap laying machines to a sole laying or leveling machine, and therefore to economize the time spent in the operations of flap and sole laying and leveling, with a consequent reduction in the cost of manufacture, I have in the present instance utilized the jack of the beating out machine as a support for the shoe, upon which it is mounted prior to the beating out action of the machine. By this arrangement the operative after once jacking the shoe can immediately use the portable power channel flap layer to relay the channel flap of the sole and then operate the beating out machine to level the same without any loss of time. Referring now particularly to Figs. 2 and 3, said hangers 1 are formed as a yoke. the arms 4 of whichpivotally support horizontal boxes or bearings 5 in which a drive shaft 6 is journaled, said shaft having at its right end the usual fast and loose pulleys 7 and 8 respectively, adapted to be connected with a convenient power shaft (not shown). This shaft also forms the pivotal support for a counterbalance lever 9 from the front end of which the roller carrier, presently to be described, is suspended. This counterbalance lever, as here shown, is pivoted by its hub-like bosses 10 on said drive shaft 6 and intermediate said boxes 5 so as to permit it to rock or swing freely thereon, but preventing movement laterally or longitudinally of said shaft. This lever is also provided, as herein shown (Fig. 3), with a longitudinal recess or slot 11 for a pulley 12 fast on said drive shaft 6 and rotating therewith. At its front end said pivoted lever 9 is provided with a forked head 9 (Fig. 3) pivotally mounted thereon by a horizontal stud or pivot pin 9 to permit said head to rock freely thereon, the forwardly extending arms 13 of said head having suitable bearings 14 for a countershaft 15. Between the arms 13 said countershaft 15 receives a pulley 16, fast thereon and connected by a belt 17 with the driving pulley 12 on said driving shaft, the rotation of which rotates said pulley 16 and thereby the countershaft 15. This countershaft extends through its bearings 13 and at its outer ends is provided with pulleys 18, fast thereon and rotated simultaneously with said shaft. IIhese pulleys are connected by belts 19 (see Figs. 1 and 2) with grooved pulleys 20 at the outer ends of said channel flap rollers 2 and 3, by which the latter are rotated, the left belt 19 being crossed to rotate the roller 2 in opposite direction to that produced by the right belt 19 on said roller 3. Each of these rollers is loosely mounted on a flexible and pivot shaft 21 (Figs. 4 and 5) comprising two parts abutting at their inner ends which is secured at its outer ends in sockets formed at the inner ends of suitable handles 22 (Figs. 2 and 4) of convenient shape to be grasped by the hands of an operative for moving said shaft and the rollers 2 and 3 mounted thereon to a desired operative position, the rounded inner end of one section of said shaft fitting into a recess 22 of converse shape formed in the inner end of the opposite abutting section to form a flexible connection, so that the operative face of the rollers may be adapted to fit the contour of the tread face of the different styles of shoes. For normally holding the two parts of said shaft 21 in alinement I have herein provided a coiled spring 25-, connecting the rods 25 of said carrier. That this handled shaft and its flap laying rollers may be moved back and forth over the sole of a shoe mounted on said jack and simultaneously tilted vertically and swung laterally, I have, in the present instance, provided suitable oscillatory or suspension means herein shown as a horizontally swinging vertical carrier, which as has been stated is suspended from the front end of the counterbalance lever 9. This carrier comprises a pair of arms of links 23 (Fig. 2) provided respectively at their upper and lower ends with telescoping rods 24, 25, adjustabl'y secured therein. The lower ends of the rods 25 are provided with eyes 26 through which theends of said shaft 21 extend and are supported. In the present instance each of these eyes is larger in interior diameter than the shaft which it supports, each of said eyes moreover being placed between the inner end of the adjacent handle 22 and the hub of the adjacent roller pulley, such construction permitting of slight longitudinal movement of the rollers 2 and 3, loosely mounted on said shaft, but preventing more than a limited longitudinal displacement of said shaft relative to its carrier. By this arrangement of a loose connection between the shaft and its carrier, said shaft and its rollers have sufficient movement relative to the carrier to permit either or both ends of said shaft to be elevated or moved laterally or obliquely to bring the rollers into operative position relative to the shoe sole or work to be operated upon.

To similarly connect the upper end of the carrier with the counterbalance lever 9, referred to, the upper ends of the rods 24 are provided with similar eyes 27 which, in the present instance, are supported upon headed horizontal pivot pins or studs 28, carried at the outer front ends of horizontal arms 29 removably secured to said forked head 9. The interior diameters of these eyes are also larger than the horizontal pins 28 on which they are supported, so that the carrier may not only be swung back and forth to progressively move the flap laying rollers over the shoe sole, but simultaneously to permit oscillating or rocking and swinging the carrier laterally, both vertically and horizontally, by simultaneously or separately moving said handles 22 in opposite directions, thereby providing for additional movement of said shaft and its rollers to bring one of said rollers into any desired operative position relative to the shoe sole and flap to be operated upon. For adjustably securing the rods 24 and 25 in said links 23, the ends of the latter are provided exteriorly with screw threads and also split longitudinally,

the split ends receiving between them the ends of said rods which are slid vertically therein to the desired position, the threaded portion of said links 23 being provided with clamping nuts 30 which may be turned to clamp the split ends against said rods to hold them in desired position, or to express it differently, for varying the effective lengths of the carrier arms 23, which may be adjusted at will and as desired to normally maintain the axis of the rolls in a desired horizontal or oblique position. As said supporting arms are suspended from the front end of the lever 9 (Fig. 1) means are also provided for counterbalancing said lever and the weight supported thereby; said means comprising, in the present instance, a counterbalance weight 31 slidably mounted on the rearwardly projecting arm 32 of said lever and secured in any desired position'by set screws 33. By moving this counterweight back and forth on its supporting arm, the center of gravity of the system may be correspondingly moved forward or in the rear of its fulcrum to change the effective lengths of the lever arms, so-that the weight of the roller supporting arm of the lever will normally overcome that of its opposite end, depressing said rollers, or, with the rearward movement of the said counterweight, elevate the same. By adjustment of said weight 31., the lever may be norm ally maintained in horizontal position or either end may be maintained in a depressed position but in practice said weight is adjusted to a position such that the roller end is normally depressed and to produce more or less pressure upon the rolls and the work operated upon, the amount of pressure being increased as the weight is moved toward the fulcrum and decreased as it is moved away from it. The pivotal mounting of the lever upon said driving shaft 6 permits it to be elevated or depressed by hand respectively to raise it out of contact with the sole or to force or permit it to be depressed upon the sole of the shoe mounted on the jack beneath it. The eyes 26 and 27 being considerably greater in internal diameter than the said shaft 21 or the studs 28, permit of considerable lost motion at both ends of the carrier which with the pivotal otherwise, relative to any desired portion of the sole and tilted and moved at will during the operation thereof.

When not in use, or during the subsequent leveling operation of the beating out machine, the roller shaft 21 is supported adjacent its ends in forwardly extending bracket arms 38, secured to a stationary part of said beating out machine A.

Referring now to Fig. 5, the rollers 2 and 3 are sepa rated sufiiciently to permit of rotation thereof without interference, a loose idler or ring 34 having a slightly convexed edge being interposed on said shaft 21 between and to separate the opposed ends-of the rollers and constituting not only a rest for the sole but a pro-, tector or covering for the adjacent edges of the rollers, thereby preventing injurious action thereof upon the sole during the flap laying operation. Each of these rollers, as herein shown; is of general frusto-conical form having a slightly curvilinear periphery tapering towards one end, said periphery in the present instance being formed with continuous spiral grooves 35 (see Fig. 5) and intervening continuous spiral ribs 36, though obviously my invention is not limited to any particular number of ribs or grooves. As herein shown (see Fig. 5) the tapered ends of said rollers abut the idler 34 but as the rollers are loosely mounted on the pivot shaft 21 their positions may be reversed to bring the tapered ends outwardly with the portions of greater diameter in the center, the pulleys 20 being adapted to be removably secured to either end of said rollers. The edges of the ribs are herein shown as slightly rounded, to prevent any tendency to cut the flap or bottom of the shoe sole upon which they operate and to make the rollers lighter, the groove 35 in each roller is provided with a series of holes 37 (Fig. 5). When rotated, these rollers cause their ribs to act upon a channel flap and move the same longitudinally of the rollers and transversely to the direction of rotation, i. e., in a direction to lay the said flap upon or flush with the sole' from which it was cut and turned up, and also directly opposite to the oblique position in which it was turned up by the channeling tool or the usual flap turning device. This operation will be best understood by referring to Fig. 4, where S represents the sole of the shoe, supported upon the jack J, having the channel flap turned up and the rollers 2 and 3 rotating in the directions indicated by the arrows in said figure. As the right roller 2 (Fig. 4) is brought to bear upon the flap at the end of the channel on the left side of the shank of said sole S, the action of its rib on said flap will cause said flap to be turned down in a direction opposite to that indicated by the small arrow on said flap in which it was turned up. By swinging the carrier forward the roller 2 lays down the flap continuously in the manner just described to the toe end of the sole. When this point is reached the carrier is swung laterally with a twisting motion about the toe end of the sole and then the roller shaft is rocked longitudinally and vertically by elevating its left end and depressing the right (Fig. 4) to remove the roller 2 from and to bring the roller 3 into operative relation with the flap at the right side of said toe. The rib of said roller 3 being rotated in a reverse manner or oppositely to that of the roller 2 then engages the flap on this side of the sole to press it to place, the combined rotary and longitudinal effect of the beginning of the channel is reached at the right side i of the shank portion of the sole, at which point the channeling commenced. As will be apparent from an inspection of Fig. 4, the progressive movements of the rollers over the sole, that is, toward the toe on the left side and oppositely on the right side, are also opposite to the direction in which the flap was bent forward or back of its normal position when cut or turned up from the channel, so that this movement of the carrier and its rollers greatly assists in laying the flap down in the right direction.

In operating with my machine, a shoe is first mounted upon the jack J of the leveling machine, in the position indicated at J in Fig. 1, that is, with the jack in its outer horizontal position, in which it is normally carried and in which a shoe is conveniently applied to or removed therefrom.

Assuming the shoe to be suitably jacked or secured to the jack to prevent movement thereon, the operative next grasps the handles 22 carrying the channel flap roller shaft and rollers and moves the same to a position indicated in Fig. A, in which the ribs of the roller 2 are brought to bear upon the channel flap at the end of the channel. The rotation of this roller 2 causes its ribs to engage the flap at the left side of the sole, viewing the tread face (Fig. 4), and turn or lay it down in the manner described. In performing this operation, the operative depresses the left handle 22 while elevating the other, not only to bring the roller 2 into operative contact with the desired portion of the shank of the sole but to prevent the roller 3 from engaging the opposite side of the shoe. The rollers are next swung forward toward the operative, or toe of the shoe by hand, tilting the same as desired to cause the ribs of said roller 2 to lay the flap continuously down to the toe end of the sole. At this point the operative gradually swings the roller shaft and said rollers laterally to bring the ribs of the other roller 3 into engagement with the flap at the right side of the sole (referring to Fig. 4) and by a continuous move ment of the roller carrying shaft causing the oppositely rotating roller 3 continuously to lay the flap into its original position in the sole until the commencement of the sole channel is reached. This operation will ordinarily be sufficient, the channel flap being laid continuously from the end to the commencement of the channel and restored to its original position in the sole by a single oscillation of the carrier and removing the puckering or wrinkling resulting from the channeling or flap turning operation. Obviously, however, the rollers may be moved over the sole any desired number of times, or caused to dwell at any portion thereof until the flap is thoroughly smoothed out and efiiciently laid.

By'varying the position of the counterbalance weight 31 the rollers may be caused to bear with more or less weight on the sole shoe in addition to that produced by the pressure of the hands of the operative, which may be desired in working upon certain types of soles.

The carrier, with its rollers, may also be advantageously moved horizontally over the sole from the rear of the shank towards the toe end thereof, the curvilinear taper of the rollers inwardly and their rotationin opposite directions permitting the flap on each side of the sole to be laid simultaneously with but a single forward movement of the rollers, which however, may be repeated as often as desired. When operating in this manner to lay the flap simultaneously upon both sides of the sole, the flexibility of the shaft 21 permits varying the concave periphery presented by the two rollers so that different types of soles may be operated upon, the coiled spring 25 connecting the rods 25 at the lower end of the carrier normally maintaining the two sections or parts of the shaft in alinement but yielding to permit flexing it in any direction, usually vertically.

It should be understood, furthermore, that while I have described the channel flap layer as operating upon the fiap of a shoe channel continuously from the end to the beginning of the channel, the commencement of which was at the right side of the shank, obviously the machine is equally adaptable in operating upon soles in which the channel is cut in a reverse direction. In the latter case the rollers are rotated in the opposite direction to that described herein and the roller 3 is first brought in operative relation to and upon the shoe sole while the carrier is swung forward toward the toe, the roller 2 then being brought into flap laying position as described and the carrier swung rearward to its initial position, thus laying the flap continuously from the beginning to the end of the channel and in the opposite direction to that in which it was cut or turned so that it is restored to its normal position in the shoe sole.

By supporting the rotary rollers horizontally in a carrier which can at once be swung longitudinally, vertically, laterally and obliquely, the combined movements permitting the rib of either roll to be brought into any desired position relative to the shoe sole and the flap it is to lay, and caused to dwell thereon or to move progressively and under any, desired pressure to produce the efficient results desired. By employing a counterbalance, moreover, the expenditure of. energy required of an operative in manipulating the shoe under the suitable pressure required to effectively lay the flap is avoided, as the sole of the supported shoe normally sustains the weight of the rollers and their carrier.

While I have shown a jack of a beating out machine for supporting the shoe to be operated upon, obviously, any other sole pressing machine provided with a jack maintained in substantially horizontal position, or any other type of shoe supporting means may be employed, my invention not being limited in this respect, the term jack as used in the claims being generic in sense and including any form of shoe support, whatever be its construction.

My invention furthermore is not limited to the particular embodiment thereof herein selected for illustration and description only, nor to the specific constructions, details and terms used, the latter being used in a broad or generic sense and not in their specific nature, and I Wish it to be understood that minor changes may be made in the construction and arrangement of parts within the spirit and scope of my invention.

Having thus described the specific embodiment of my invention, I claim and desire to secure by Letters Patent:

1. In an organized machine of the type described, a horizontal pivoted lever, a vertical carrier pivotally connected therewith having a horizontal shaft provided with handles to facilitate swinging the carrier, flap laying members mounted on said shaft, and means for rotating said members in different directions.
