MACHINE FOR TRIMMING AND CHANNELING THE SOLES 0F SHOES.
SPECIFICATION forming part of Letters Patent No. 225,729, dated March 23, 1880.
Application filed January 10, 1880.
To all whom it may concern Be it known that I, JASON SMITH, of Rockland, county of Plymouth, and State of Massachusetts,have in vented a new and useful Improvement in Machines for Trimming and Channeling the Soles of Shoes, of which the following is a specification.
My invention relates to certain improvements in machines for trimming and channeling the soles of shoes, in which the sole to be operated upon is clamped to a form or pattern resting upon the disk of a horizontal revolving plate, and by means of a compound flexible arm a carrier-block, carrying both a trimming and a channeling knife, is held against the edge of the pattern in such a way that as the form is revolved against the knives the sole is both trimmed to the shape and size required, and the channel to receive the stitches is cut at the required distance from the edge and of suitable depth and form, both operations being performed at the same time and by a single revolution of the disk.
The mechanism which I employ to accomplish this purpose is illustrated in the drawings accompanying this specification, in which- Figure 1. is a side elevation of my invention. Fig. 2 is a plan, showing the top of the revolving plate with the form to receive the sole and the cam-groove surrounding it, also the position of the compound flexible arm and the knife-carrier block, the overhanging part of the frame with the clamping apparatus being removed. Fig. 3 is a cross-section taken on a horizontal line to include the center of the disk and the center of the knife-carrier block, as indicated by the dotted line in Fig. 1. Fig. 4 is an enlarged view, showing the position of the difierent parts of the flexible arm and. the roller within the cam-groove, also a front view of the knife-carrier block, with the knives in their position when at work. Fig. 5 is an enlarged perspective view of the knife-carrier block complete. Figs. 6 and 7 show the construction of the pattern that gives shape to the sole.
The frame A is made of a suitable form to receive the revolving plate B, and may be secured to or made a part of any suitable table, and the plate B may be geared to be operated The plate B is shown with handles projecting from its periphery; but these will, of course, be unnecessary if the machine is operated by power. It may also be pivoted to the frame by being mounted upon the end of a shaft, or in any other suitable manner.
The pattern Z1 rests upon the form I), and is placed centrally upon the disk B, and is surrounded by the cam-groove e, which is made to conform somewhat nearly to the shape of the sole of a shoe, as shown.
To an offset on the frame A the arm at is pivoted, and at its free end has a stud, d, fitted, the lower end of which receives a roller that moves within the groove 6. The arm or lever c embraces the stud d, swinging loosely thereon, and by means of the spiral spring (1 its long end is pressed inward or against the pattern b. The tension of the spring is regulated by the position of the clasp (P, to which one of its ends is secured, as shown in Figs. 1 and 4.
The knifecarrier block Gr consists of two parts, the upper part, 9 being fitted to slide upon the pins hh, that are secured to the lower part, 9, and is held down upon the latter by the action of the springs 71. It. Within a recess made in the part g a cam or dog, i, (see Fig. 3,) is secured to the shaft i, and by means of the handle '5 the part g is raised, thus raisin g the channeling-knife when entering the work.
The trimming-knife may be said to consist of three parts-the knife proper, It, the part which forms the gage to rest against the pattorn and guide the knife, and the shank by which it is secured'to the stem 9.
The knife 70 may be made integral with the other parts, or it may be made separate and be secured to the gage in any suitable manner. The shank is inserted into a slot within the stem g, as shown by the dotted lines in Fig. 4.
The position of the knife-carrier block when at work is at a right angle with the edge of the pattern at the point of contact, and'the gage k is placed centrally with the stem 9 in its line of motion around the pattern, with the knife is at a slight distance back of the center, thus giving the knife a little drag, by which it is held more closely against; the edge of the pattern, and the motion of the whole carrierby steam-power instead of by hand, if desired.
block is more steady than if the edge of the knife were exactly over the center of the stem g.
The channeling-knife l is fitted to the part 9 and is placed so that the cutting-point projects beyond the trimmingknife as much as the required distance of the channel from the edge of the sole. Its cutting-edge is inclined at an angle to give the proper form of channel, and a gage, Z, regulates the depth of the cut. The channeling-knife is secured in its place by suitable screws, and the gage l is clamped between the knife 1 and the part 9, as shown in Figs. 4 and 5.
The pattern b has two or more holes, which embrace corresponding pins that project above the surface of the form I), and is provided with barbs or points that project above its two surfaces, thus admitting of its being used either side up, and consequently both rights and lefts can be made with the same pattern. Inasmuch as the sole is always put upon the shoe with the grain side out, with the channel upon the outer side, it is necessary that the sole should be placed upon the pattern with the grain side up, as the channel is made upon its upper surface. It is therefore desirable that there should be no barbs in the clamp, as it would leave indentations on the grain side to mar the surface.
By putting the barbs into the pattern I am enabled to use a clamp having no points, and therefore avoid scarring the finish surface of the work.
The clamp b is fitted to turn loosely upon the lower end of the spindle D which spindle has a reciprocating motion within the end of the frame above the disk, as shown. A spiral spring around the spindle is arranged to raise it, with the clamp b above the pattern, except when held down by the action of the handlever m.
I To operate the machine, the sole, cut roughly to a form somewhat nearly of the shape required, is laid upon the pattern b, and the clamp b is pressed down upon it by means of the hand-lever m. The channeling-knife, having previously been raised, is let down so that the point of the knife rests upon the surface of the sole. The disk B is now revolved against the knives, or in the direction shown by the arrow, and with the gage k bearing against the edge of the pattern and the gage 1 upon its upper surface, the sole is trimmed to the exact size and shape, and a channel of a uniform depth and distance from the edge is made at the same time by a single revolution of the disk B..
It will be observed that the angle at which the arm 6 is presented to the edge of the pattern is such that when the disk is revolved the resistance offered by the work of the knives causes the gage k to hug closely to the pattern, and that therefore the knife-carrier block is not dependent entirely upon the strength of the spring (I to keep the gage against the pattern while at work; also, that when at work the downward pressure of the part 9? is borne entirely by the gage l, which rests upon the surface of the sole, and as it moves over the surface the part g rises or falls with the gage and knife lin passing over inequalities in the thickness of the leather, and thus adjusts itself to the thickness of the sole, and insures a uniform depth to the channel.
I am aware that machines for trimming soles to a pattern have been used wherein a single knife is carried around the pattern also, wherein the sole is clamped to a stationary pattern while the knife is moved around the same.
What I claim as my invention, and, desire to secure by Letters Patent, is-
1. A machine for trimming and channeling the soles of shoes, consisting of the revolving plate B, secured to and operating upon a suitable frame, and having upon its disk a form or pattern to receive the sole, and of the knifecarrier block Gr, secured to a flexible arm, whereby it is held in such proximity to the pattern that as the plate A is made to revolve on its axis the knives within the carrier-block will be presented to the work so as to both trim the sole to the size and shape of the pattern and to cut a channel to receive the stitches at one and the same operation, substantially as shown and described.
2. The knife-carrier block Gr, pivoted to the arm 0, and consisting of the pivoted part 9, with the trimming-knife Is and gage 7c, and the part 9 connected therewith, and having a self-adjusting vertical movement, as shown, and having the channelingknife l and gage Z, all arranged and operating to trim the sole to pattern and cut the channel at one operation, substantially as shown and described.
3. In combination, the revolving disk B, with the form 7), pattern b, and cam-groove c, the knifecarrier block G, attached to the compound flexible arm d and e, and swiveled clamp b all constructed as shown, and operating so that the sole b will be trimmed to the shape and size of the pattern b, and the channel to receive the stitches made at the same operation, in the manner shown and described.
