Definitions
- Our invention relates to an improved machine for trimming and channeling the soles of boots and shoes, its objects being to provide a simple and highly-efficient device in which the knives may be independently and easily and quickly adjusted to adapt the machine to various designs or styles of boots or shoes while the machine is in motion and the boot or shoe is being operated upon, to increase or diminish the width of the extension or projecting edge of the sole as is reuired in different designs and shapes and a so as is necessary for the reason that the extension upon most boots or shoes is greater upon one side than the other, and, further, to permit the correct shaping of the sole in the shank.
- Another object of the invention is to provide a feeding device for feeding the sole against the cutters and which operates upon that portion of the sole that is afterward severed from the body portion, thus leaving the latter perfectly solid and free from unnecessary abrasions or cuts.
- Still a further object of the invention is to provide for a quick adjustment of the guard to permit the ready insertion and removal of the boot or shoe; and still a further object is to provide an adjustable guard to facilitate both rapidity in cutting and as a guard against mishaps due to quick work or carelessness on the part of the operator.

Application filed November 9, 1905. Serial No. 286,546.
To all whom, it may concern:
Be it known that we, WILLIAM EDWARD SMALL and ROBERT CAMPBELL, citizens of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Shoe-Sole Trimming and Channeling Machines, of which the following is a specification.
Our invention relates to an improved machine for trimming and channeling the soles of boots and shoes, its objects being to provide a simple and highly-efficient device in which the knives may be independently and easily and quickly adjusted to adapt the machine to various designs or styles of boots or shoes while the machine is in motion and the boot or shoe is being operated upon, to increase or diminish the width of the extension or projecting edge of the sole as is reuired in different designs and shapes and a so as is necessary for the reason that the extension upon most boots or shoes is greater upon one side than the other, and, further, to permit the correct shaping of the sole in the shank.
Another object of the invention is to provide a feeding device for feeding the sole against the cutters and which operates upon that portion of the sole that is afterward severed from the body portion, thus leaving the latter perfectly solid and free from unnecessary abrasions or cuts.
Still a further object of the invention is to provide for a quick adjustment of the guard to permit the ready insertion and removal of the boot or shoe; and still a further object is to provide an adjustable guard to facilitate both rapidity in cutting and as a guard against mishaps due to quick work or carelessness on the part of the operator.
With these briefly-stated objects in view the invention also comprises certain details of construction and peculiar combination and arrangement of parts, as will be fully set forth in the following specification and pointed out in the claims, reference being had to the drawings, in which Figure 1 illustrates in perspective our invention complete. Fig. 2 is a face view. Fig. 3 is a central sectional elevation drawn on about the line 3 3 of Fig. 2. Fig. 4 is a detail perspective view looking at the rear of themachine. Fig. 5.is a detail horizontal section drawn on the line 5 5 of Fig. 3. Fig. 6 is a detail sectional plan view of the bracketarm carrying the knife for trimming or cutting the edge of the sole. Fig. 7 is a detail side view of the feed-wheel and the bracket to which the channeling-knife is secured. Fig. 8 is a detail face view of the feed-wheel and knife for cutting or trimming the edge of the sole and illustrating its position in relation to the foot. Fig. 9 is a detail view of the bar carrying a presser-roll that holds the sole of the shoe against the foot. Figs. 10, 11, and 12 are detail views of the arm carrying the channeling-knife, the channeling-knife, and the bracket in which the said arm operates. Fig. 13 is a detail view of the knife for trimming the edge of the sole and the arm to which it is connected, and Figs. 14: and 15 are detail views of the presser-foot.
In the manufacture of boots and shoes the uppers are first sewed to the welts, and the soles are then cemented upon the welts and after being allowed to thoroughly dry are turned over to the operator to be stitched, after which the heels are secured in position. Then the shoe is ready for polishing and the final touches necessary to a finished article; but before the heels are secured in position the soles are trimmed and channeled preparatory to stitching, it being understood that the channels are cut eXteriorly to provide a recess for the loops of the stitches, and the lip produced by the channel is bent down over the stitches, completely covering them, which leaves the bottom perfectly smooth and flat, and to facilitate this work is the purpose of our invention.
A complete understanding of the mechanism of the machine by which we attain the aforesaid results will be readily understood from the following description, taken in connection with the drawings, in which like reference characters indicate corresponding parts in all figures, and by reference to the drawings it will be seen the frame comprises a base A, that is supported upon a suitable stand B, and A is a front or face plate projecting vertically from the forward edge of the base, the vertical edges of which are increased in thickness, as at A and upon the upper ends of the said portions are bolted plates A, which with the front plate and the edges of the thickened portions provide guideways in which is slidably retained a head C, having a hub C proj ecting rearwardly from the upper end thereof and through an opening a in the face-plate, and journaled in the hub is a shaft D, having at its forward end a toothed feed-wheel D and at its opposite end a gear D which is meshed by a suitable drive-gear. (Not shown.)
The head C is normally held at the upper end of the face-plate by means of a spring C held between. a lug c at the base of the head and a tension-nut (1, held upon a threaded sleeve a projecting up into the spring, and from a lug a extending from the base A at the lower end of the face-plate and projecting through the spring and sleeve, and connected at its upper end to the lug c is a bolt M, to the lower end of which is connected a link to which is secured a rod or chain a whose lower end is connected to a treadle a, and it will be understood that by depressing the treadle the face-plate and the parts carried thereby will be drawn downwardly for the purpose as will appear later on.
Projecting rearwardly from the upper end of the face-plate and upon each side of the opening a are brackets a uponwhich and the upper end of the faceplate is held a block a having a channel a in its upper surface in which operates a bar E, whose forward end projects downwardly, as at E, and then forwardly in a horizontal plane to provide a presser-foot E which extends over the periphery of the feedwheel. In the lower side of the foot is ournaled an antifriction-roller E against which the upper portion of the sole that projects from the shoe-upper engages. The extreme end of the foot being rounded forms a smooth contacting surface against which the shoe-upper engages. The upper face of the bar E is provided with rack-teeth E", that are meshed by a pinion E, carried by a shaft journaled in lugs e, projecting up.- wardly from a plate E", that is bolted to the top of the block. One end of the shaft proj ects beyond. the end of the block and carries a crank-arm to which is connected a chain or rod 6, whose opposite end is connected to a foot-treadle 6 The rear end of the bar terminates in a downwardly-extending aper tured portion E through which projects a threaded bolt E, carried by the block, and upon the bolt is a regulating-nut E, that is engaged by the downwardly-extended portion to limit the forward movement of the bar when the treadle is operated.
Extended forwardly from the sliding head are parallel brackets C having channels along their upper inner edges in which operates a slide-bar F, that is securely held in place by a plate C bolted to the brackets, and to the front edge of the bar is secured a vertically-disposed bracket-arm F, having undercut flanges F forming guides designed to receive flanges G carried by an armG and by which the arm is slidably held to the face of the bracket-arm. The rear upper end of the arm is cut out to provide a shoulder g, and in the cut-out portion is formed a dovetail groove 9 in which operates a correspondinglyshaped tongue 9 formed upon a slide or plate G to which is held a channel-cutting knife-blade G said blade projecting upwardly at a slight angle from the plate and has its free cutting end bent upwardly and forwardly, as at G A slotted bar G is adjustably held to the side of the arm G by screws 9 and has its upper end provided with a lateral extension projecting over the top of the bar and to which is journaled a presserroller G, which projects under the presserfoot and is disposed directly in front of the cutting edge of the channel-knife.
To the lower end of the arm G is connected a threaded bolt G which extends down through a foot F projecting forwardly from the lower end of the bracket-arm, and sur rounding the bolt is a spring G which bears at one end against the foot and at its opposite end against a tension-nut G, threaded upon the bolt. This spring is designed to normally hold the arm G upwardly, so that the roller G will engage the lower side of the sole to press and hold it into engagement with the presser-foot, and in order to limit the upward movement of the arm I employ setnuts G ,which engage the under side of the foot F The bar F projects through an opening f in the head and through an elongated opening f in the face-plate, and to its rear end is pivotally connected a plate F", the vertical edges of which are retained in grooves H, formed in the vertical portion H of an L- shaped lever crank-arm H that is pivotally held between brackets 0, projecting rearwardly from the face-plate of the frame, and connected to the horizontal member H of the crank-arm is a rod or chain h, that is also connected to a foot-treadle h. To the member H is connected a spring h that is designed to hold the arm in its normal position and to return it to its normal position when pressure on the treadle is released.
H and H indicate stop-screws carried by extensions of the brackets 01, and are designed to. engage the horizontal member of the crank-arm to limit the movement when the arm is operated by the treadle.
Connected to one of the plates A is a plate I, having a dovetail tongue 71 upon its front face which operates in a similarly-shaped groove formed in the rear end of aforwardlyprojecting bracket-arm J, and in the side of the bracket-arm J and at its forward end is arranged a dovetail groove j, in which is held a dovetail rib 70, formed upon an elongated block K, the side of which opposite the arm having a dovetail groove 7c, in Which fits a similarly-shaped rib Z, formed upon a plate L, to the face of which is bolted or otherwise secured an upwardly and outwardly extending arm L, that extends over the peripheral edge of the feed-Wheel, and to the free end of the arm is secured a knife-blade M, that is designed to engage and cut or trim the edges of the sole. As shown in the drawings, the upper end of the cutting edge of the knife-blade rests within a recess produced in one edge of the foot E Projecting from the plate I is a threaded stem I, upon which operates a thumb-nut I held in a bracket j carried by the bracket-arm J, and by turning the nut the bracket-arm, and consequently the knifeblade M, will be moved away from the presserfoot E A similar adjustment N is provided to regulate the vertical movement of the block K, and a similar arrangement O is also provided for adjusting the plate L horizontally, and it will be understood by these various adjustments we are enabled to adjust the knife-blade M to any desired position with relation to the presser-foot and feed-wheel that may be desired according to the work to be done.
The operation of our machine is as follows: The shoe-sole after having been cemented to the welt is readily inserted between the presser-foot and the feed-wheel by pressing down upon the treadle a, which draws the head and the parts carried thereby downwardly to increase the space between the feed-wheel and the foot, and when the treadle is released the spring C will elevate the head and throw the feed wheel or disk into engagement with the sole, which being constantly revolved will immediately begin to draw or feed the sole against the knifeblade M, which trims the edge of the sole, and also into engagement with the channelingblade G which makes an incision in the lower face of the sole and immediately adjacent the edge. The sole is thus guided through the machine until the entire surface is operated upon, and as it is often desired to increase the width of the extensions upon one side of the shoe and also decrease it at the shank the bar E is forced outwardly at the desired points by pressing upon the treadle e which throws the foot against the side of the shoe-upper, and consequently forces the shoe away from the cutters, thereby increasing the distance between the end of the presserfoot and the cutting-blades, consequently leaving a larger projection or extension upon the side of the shoe. It may be stated that the sole is first inserted in the machine at the shank and the presser-foot is left in the position shown in the drawings, which maybe termed its normal position,for the reason that the extension of the sole is always narrowest at the shank; but as the sole is being fed through the machine the operator presses upon the treadle e throwing the foot outwardly, which engages the side of the shoeupper and forces it away from the cutters, thereby increasing the Width of the extension, and as the channels of the shank of the sole are cut farther from the edge than at the fore part it is necessary to provide arrangement for adjusting the bracket-arm carrying the channeling-knife we employ the crank arm, which is connected to the bar that supports the bracket-arm, as shown and described, and it will be readily understood that by pressing upon the treadle h the crank will be tilted and the bar F projected through the head, which, carrying the bracket-arm, will draw the channel-knife away from the trimming-knife M, and thereby increase the diritance of the channel from the edge of the so e.
In practice we propose to make the top part of the face-plate of the frame much nar rower than the lower portion, so that the boot or shoe may be readily guided through the machine without contacting therewith.
From the foregoing it will be seen we provide an exceedingly simple device for the purpose hereinbefore stated, and it will be particularly noted that any style or shape of shoe or boot may be trimmed or channeled.
without any special adjustment of the machine other than the bracket-arm J and the parts carried thereby, as it will be understood that other adjustments may be accomplished while the machine is in motion and the sole operated upon by merely operating the treadles.
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
1.
