T 0 all whom it may concern:

Be it known that I, JOHN G. Boss, a citizen of the United States, residing at South Easton, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Channeling- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in channeling machines.

In the manufacture of welted boots and shoes the insole is usually provided with a channel in its marginal portion and the edge of the sole is split to form a lip for the reception of stitches.

The present invention relates to improvements in machines for performing one or both of these operations upon a sole or an insole, and its object is to simplify and improve the construction of such machines in the respects hereinafter pointed out.

Other objects of the invention will be noted in connection with the description of the illustrated embodiment thereof.

To the above ends the invention consists in the improved channeling machine hereinafter described and defined in the claims.

In the drawings illustrating the preferred form of the invention Figure 1 is a front elevation of the machine; Fig. 2 is a left hand side elevation; Fig. 3 is a right hand side elevation; and Fig. 4 illustrates the manner in which the knives operate upon the insole.

The illustrated embodiment of the machine comprises as its operating instrumentalities a channeling knife 1 and an edgeslitting knife 2, together with a work support 3 and suitable mechanism for actuating these parts to cause them to feed the work and cut the channel and the slit. The work support 3 is in the form of a truncated cone mounted on a stem 4 journaled in a bracket 5 on the frame of the machine. The work support is mounted unyieldingly, the necessary adjustments for different thicknesses of work being embodied in the parts by which the knives are supported and actuated. The work support, therefore, forms a rigid support for the work and cannot yield to the thrust of the channeling knife. The work support performs the operation chine and connected with the slide by a pinand-slot connection, as shown in Fig. 2. The lever 9 carries at its upper end a cam roll engaging a cam 10 upon the shaft 11 of the machine, and the cam roll is held against the cam 10 by a spring 12 connected with the lever 9 and the frame of the machine. To prevent retrograde movement of the work support a friction washer 13 is pressed against the stem 4 of the work support by a screw 14.

The channeling knife is arranged to vibrate transverse with respect to the line of feed so as to cut the channel by a succession of chopping cuts which overlap to form a continuous channel. The knife is adjustably fixed as shown in Fig. 3, by means of screws 15 engaging a horizontal slot in the knife, to a knife carrier 16 which is mounted on a lever 17 by means of screws 18 engaging a slotin the knife carrier so as to permit vertical adjustment of the knife carrier. The lever 17 is pivoted at 19 upon a head 20 so as to have an oscillating movement, and the ever the thickness of the work may vary,

the head 20 is arranged to rise and fall, carrying the pivot 19 and, the parts mounted thereon with it, and such rising and falling movements are controlled by a presser .foot 26 fixed to the head 20 and bearing upon the surface of the work. The head 20 is adjustably connected by a horizontal shank 27 withan arm 28 pivoted at 29 on the frame of the machine and pressed downward so as to hold the presser foot in engagement with the work by a spring 30 connected with the frame of the machine by an adjusting screw 31. The shank 27 is slotted at 50 and a binding screw 51 passing through the slot fixes the shank in place. By means of an adjusting screw 52 passing through the head 20 into the arm 28 the head may be adjusted horizontally when the binding screw 51 is loosened, and in this way the position of the center of oscillation of the knife carrier may be adjusted horizontally so as to vary the distance between the channel and the slit and determine the thickness of the between substance. The link 21 connecting the lever 17 and the slide 23 permits rising and falling movements of the lever 17 and parts carried thereby without interference with the vibrating movement transmitted to the channeling knife, and since the relation of the presser foot 26 and the pivotal support 19 of the channeling knife is fixed the knife cuts always to the same depth below the presser foot, and thus its action is uniform whatever the thickness of the work. The vertical adjustment of the knife carrier 16 on the lever 17 in connection with the vertical adjustment of the presser foot permits the distance between the channeling knife and the pivot 19 to be changed and in this way the center of oscillation of the knife carrier may be adjusted vertically and the radius of oscillation of the channeling knife may be varied to vary the form of the channel which is cut, and the depth of the channel may be adjusted by moving the presser foot 26 Vertically upon the head 20, the presser foot being for this purpose connected adjustably to the head by screws 32 engaging slots in the shank of the presser foot, as shown in Fig. 3. It will be obvious that the form of the channel which is out can also be varied by the horizontal adjustment of the head 20 and transverse adjustment of the channeling knife 1 on the knife carrier 16. A horizontal adjustment of the head 20 followed by a transverse adjustment of the knife 1 changes the angle of the cut with relation to the adjacent surface of the work support. In order to prevent accidental contact between the channeling knife and the work support when no work is in the machine a stop screw 33 is arranged to limit the downward movement of the arm 28. The edge-slitting knife 2 also operates by a succession of reciprocations transverse to the line of feed so as to slit the soles by a series of overlapping cuts. The edge-slitting knife is mounted on a slide 34 having bearings in a carrier 35 and it is actuated by a lever 36 pivoted on the frame of the machine and connected with the slide by a pinand-slot connection. The upper end of the lever 36 carries a cam roll engaging a cam 37 on the shaft 11, and the cam roll is held against the cam by a spring 38 connected with the lever 36 and the frame of the machine.

In order that the position of the slit in the edge of the insole may be varied, means are provided for adjusting the distance between the edge-slitting knife and the surface of the work support. The carrier 35 is pivotally connected at 39 to the frame of the machine and its forward end may be raised and lowered so as to change the path of movement of the edge-slitting knife. As it is usually desirable that the thickness of the feather may be constant, an adjustable stop screw 4.8 is provided, against which the carrier 35 may rest during the operation of the machine, being drawn downward by a springt connected with the carrier by a screw 45, so that the distance between the edge-slitting knife and the work support remains constant as adjusted. If, however, it is desired to make the lip of the insole of constant thickness, it is necessary to determine the position of the edge-slitting knife by the position of the upper surface of the work, and in order that this may be done when desirable a presser foot 10 is secured to the carrier by means of adjusting screws 41 and 42 acting to draw the shank of the presser foot against a pin 13 on the carrier 35. The presser foot is drawn against the surface of the insole by the spring 4 1 and maintains the edge-slitting knife at a constant distance from the surface since the carrier 35 is free to rise and fall with the presser foot. l/Vhen the machine is operating in this manner the stop screw 48 is lowered so as not to interfere with the movements of the carrier, but it may serve as a stop to prevent contact between the edge-slitting knife and the work support when there is no work in the machine.

An edge gage 46 for gaging the depth of the cut produced by the edge-slitting knife is adjustably mounted on the carrier 35 by means of screws 47 engaging slots in the shank of the edge gage.

In the operation of the machine the work is held by the operator upon the inner surface of the work support, being pressed thereagainst bythe presser feet 26 and 40, and the rotation of the shaft 11 causes the knives to engage the work simultaneously and then to simultaneously retreat therefrom, and while the knives are out of operative engagement with the work the work support is rotated through a small angle to feed the work for the next out. As the thickness of the work varies the presser feet cause the supporting and actuating mechanisms for the knives to rise and fall so that the paths of movement of the knives and the cuts produced thereby have always the same position relative to the upper surface of the work.

A machine in which the channeling knife and the edge-slitting knife vibrate transversely to the line of feed has previously been proposed, and it is not intended to claim such a machine broadly, the present invention being directed to the improved means for feeding and supporting the work and controlling the movements of the knives. The several adjustments of the channeling knife and its actuating and supporting mechanism permit the arrangement of the knife to cut a channel of any desired dept-h, form, and position. The use of a yielding support for the channeling knife permits the use of an unyielding work support and edge-slitting knife carrier, where it is desired to make the feather of constant thickness, whereby the construction of the machine is simplified, and it is new, so far as the applicant is aware, to mount a channeling knife vibrating transversely with respect to the line of feed upon a carrier arranged to yield in accordance with the thickness of the work, whether in combination with a fixed or a yielding Work support.

The invention is not limited to the details of construction and operation described in connection with the illustrated embodiment thereof, but may be embodied in other forms broadly defined in the claims.
