assigner to United Shoe Machinery Corporation, Paterson, N. J., a corporation of New Jersey Original application July 7, 1934, Serial No. 734,129. Divided and this application March 5, 1936, Serial No. 67,342. In Great Britain July 29, 1933 18 Claims.
My invention relates to machines for operating upon the soles of shoes, it being especially applicable to apparatus by which rounding and channeling operations are performed.
D In an application for Letters Patent of the United States for improvements in Methods of and machines for operating upon shoe-soles, filed in my name in the United States Patent Oice on July '7, 1934, the serial number being l 734,129, and of which the present application is a division, is disclosed a novel method of producing about the forepart of soles what is known as an English channel and at the opposite sides of the waist or shank, an American channel. This American channel is formed by first cutting an English channel at the waist in connection with the operation upon the forepart, and thereafter deepening and widening the channel and rounding away a portion of the sole-margin until said channel opens through the edge of the sole instead of through the tread-surface. The rst, or English-channeling operation, may be performed by an apparatus of the character of that which is the subject of Letters Patent of the United States No. 1,030,606, Perry, June 25, 1912.
The transformation of this English channel at the waist-portion of a sole into an American channel may be by a modification of the machine of the Perry patent. It is an object of my invention to arrange, in such an apparatus, for the correct presentation of the previously channeled sole to the instrumentalities which are to further operate upon it. To this end, I cause the sole to be gripped, as between a feed-plate and a sole-support, in the desired relation to a channeling knife, the position of the work being determined by a crease-guide. Said work is then allowed, through movement of the guide, to be raised into operating position to receive the ac- L10 tion of the channeling knife and of a rounding knife. The former knife, lowered for the engagement, will increase the depth of the already cut channel and will widen the opening to give, when the channel is closed, a thinner sole-edge,
45 while the latter knife, by narrowing the solemargin, causes the emergence of the channel through the sole-edge. Sequential operation of the elements is preferably attained by a single member actuated by the operator, there being 50 illustrated herein for this purpose a treadle-rod.
This rod, acting through a second rod and connecting lever, rst eiTects the clamping ofthe work to be presented to the elevated channeling knife and temporarily maintained out of operating position by the crease-guide, and then raises the guide and lowers the channeling knife, the location cf the guide permitting the work to assume a position in which both the rounding knife and channeling knife may operate.
In the accompanying drawings is shown a particular embodiment of my invention,

Fig. 7, a view similar to Fig. 6, but showing the condition of the work after the machine has operated upon it.
As already indicated, my improved machine may be of the general character of that disclosed in the Perry patent. This machine comprises a reciprocating rounding or trimming knife 39, a block or sole-support 4l, an oscillating channeling knife 43 carried by the sole-support, afeed-plate 45, a crease-guide 41 and a stickerpoint 49. No forepart-guide is necessary. The machine is provided with two treadle-rods 5l and 53, respectively, for controlling the retraction of the sole-support 4I from the feed-plate 45 and for controlling the height'wise level of the sole-support 4I and of the crease-guide 41 with respect to the rounding knife 39. In the present machine, only one treadle (not shown) is provided. This is attached to the rod 53, and the rod 5I is connected with the rod 53 in order that the single treadle may operate both. Pivoted to the lower end of the rod 5I is a lever 55, which lever is fulcrumed at 5l on the column 59 of the machine. 'I'he left-hand end of the lever 55 (Fig. 2) is forked to embrace the rod 53, and, just above the forked end of the lever, this rod has a collar 6I secured upon it. The arrangement is such that depression of the treadle will another arm of which is formed as a depending hand-lever 65. The bell-crank-lever is secured to a rock-shaft 61, which also has fast upon it an arm 69 arranged to engage a lug 1| upon a sleeve 13. This sleeve is secured upon a shaft 15, which has a support 11 fixed at its forward end. The support 11 has mounted upon it a carrier-slide 19 on which the sole-support 4| is arranged for limited rocking movement in an arcuate guideway 8|. The extent of rocking movement is limited by a pin 83 (Figs. 4 and 5) in the slide entering a slot 85 in the sole-support. The shaft 15 is capable of slidingaxially in its bearing to move the sole-support toward and from the feed-plate 45, and a'spring 81 engaging its rear end tends to urge the shaft forwardly. The maximum permitted forward movement of the shaft 15 is limited by the engagement of a flange 89 upon the sleeve 13 with the front bearing 9| for the sleeve and the shaft 15. The shaft is rocked during the operation of the machine to communicate an oscillating motion to the sole-support 4| and so to the channeling knife 43. This rocking motion is obtained from a cam-actuated bell-crank-lever 93 (partly seen in Fig. l) slidably mounted upon the shaft 15 and carrying a pin 95 extending into a recess in an arm 91 formed on the sleeve 13. The construction of the elements just described is quite usual in rounding and channeling machines of the Goodyear type. Commonly in such machines, the sole-support normally occupies an advanced position and is only retracted from the feed-plate by depression of a treadle when it is desired to insert the margin of an outsole to be rounded and channeled. In the present machine, however, it is preferable to arrange the sole-support 4| normally in a retracted position. This result is attained by providing a tension-spring 99 attached at its upper end to a collar xed on the rod and at its lower end to a hook |03 in the column 59. The strength of the spring is such that it normally serves to overcome the action of the spring 81 and retains the shaft 15 and sole-support 4'| in retracted position. This position is controlled by engagement of the handlever 65 with an adjustable stop-screw |05 on the frame. The sole-support 4| is only advanced toward the feed-plate 45 to grip the work, when the rod 53 is depressed by its treadle and the rod 5| consequently raised through the lever 55.
The arrangement of the machine is such that depression of the rod 53 causes the sole-support 4| and channeling knife 43 to be lowered and the crease-guide 41 raised. The change of position of these parts upon depression of the treadle connected to the rod 53 will be appreciated by comparing Figs. 4 and 5. Mechanism for causing heightwise motion of the channeling knife upon depression of a treadle is old in rounding and channeling machines and is described in detail in the Perry patent. Consequently, this mechanism in the present machine will be but briefly described. The rod 53 has an adjustable collar |01 mounted thereon near its top and below the collar passes freely through a sleeve |09, which is pivoted at one end of a lever carried upon a rock-shaft 3. Such a lever is ordinarily employed in rounding and channeling machines of the Goodyear type, to cause the forepart-guide to be brought into or out of operative position. Since in the present machine the forepart-guide is not necessary, the actual work-engaging portion thereof may be removed, and the movement of its pivoted arm used only to effect the depression of the crease-guide 41. Such depression may be brought about by engagement of a, roll on the arm of the forepart-guide with a plate on the arm of the crease-guide. This is as in the Perry patent. At the end opposite the sleeve '|09, the lever carries a roll ||1 within a cam-slot ||9 in the lower end of a lever |2| fulcrumed on the frame at |23. The upper end of the lever |2| is provided with a guideway |25, in which a pivot-block is secured in adjusted position and is connected by a link |21 with an arm |29 extending downwardly from a rock-shaft |3I. This rock-shaft has a rearwardly projecting arm |33 secured thereto and joined by a link |35 and arm I|31 to usual mechanism for controlling the carrier-slide 19 and therefore the heightwise position of the sole-support 4| and channeling knife 43. The arrangement is such that turning of the lever in a clockwise direction (Fig. l) by a depression of the treadle-rod 53 will cause the carrier-slide with the channeling knife to be lowered with respect to the support 11.
The form of the channeling knife 43 will be apparent from Figs. 3, 4 and 5. The stem of the knife is secured to the sole-support and has a portion extending upwardly therefrom. The knife bends over forwardly and downwardly and its cutting edge |39 extends more or less vertically and may be about three-eighths of an inch in length, its lower portion extending below and a slight distance outside the top edge of the solesupport. The cutting edge is not quite straight, but is slightly curved to adapt it to make the channeling cut |1, 9 shown in Fig. 7. It has been found preferable to make the rocking movement of the sole-support 4| in the guideway 8| rather more restricted than is usual in rounding and channeling machines of the Goodyear type. This may be seen in the length of the slot 85 (Figs. 4 and 5).
A portion of a shoe to be operated upon by the machine of this invention is partially shown in Fig. 6 as being upon a last and having an upper 3, an insole 5, a welt 1, an inseam 9, an outsole and bottom-filling I3, the waist-portion of the outsole having already had formed in it an English channel .I5 from one end of the breastline to the other about the forepart. It is presented to the machine of the present invention at one end of the waist at one side of the shoe, as shown in Fig. 4. The flap of the channel formed by the cut |5 will preferably have been opened slightly, to permit the operator so to present the work to the machine that the channeling knife 43 enters readily into the cut. As seen in Fig. 4, before the operator depresses the treadle connected to the treadle-rod 53, the crease-guide 41 occupies such a lowered position that, until it is raised, the channeling knife cannot enter farther into the cut l5, and the outsole margin lies out of the path of the rounding knife 39. The operator now depresses the treadle, raising the rod 5|, and the spring 81 is allowed to advance the sole-support 4| against the treadface of the outsole. The work is thus so held between the crease-guide and feed-plate 45 and the sole-support that the blade of the channeling knife is retained in the cut I5. Upon continued depression of the treadle, when the rod 53 has been moved downwardly sufficiently for the collar |01 to contact with the sleeve |09, the channeling knife is lowered and the crease-guide elevated. The operator will keep the shoe pressed upwardly in-engagement with the crease-guide. The parts 4are now in operating position, as seen in Fig. 5, and the sole-edge is advanced in the path of the -rounding knife 39, which will trim off the surplus -margin as indicated by the line |43 (Fig. 5).
At the same time, the channeling knife will deepen the cut already made in the outsole to produce the American form of channel seen in Fig. 3 and will remove a wedge-shaped piece of material from the sole-edge, thus reducing the thickness. When the waist-portion of the outsole at one side of the shoe has been operated upon, the opera-tor will allow the treadle to rise and will remove the shoe, turn it over and operate similarly upon the YWaist-portion of the outsole at the other side. The effect of the operation will be to transform the English channel previously cut in the waistportion of the outsole into an American channel `and to 'simultaneously round the outsole and welt. Further, material will have been removed from the waist at each side, so that a desirable thin-edged appearance will be imparted to this portion of the outsole in the finished shoe.
