IMPROVEMENT IN vSOLE-CHANNELINC- MACHINES.

Specification forming part 4of Letters Patent No. 141,025, dated July 22, 1873 application led February 15, 1873.

To all whom it may concern:

Be it known that I, CYRUS C. BALLOU, of the city and county of Albany and State of New York, have invented certain Improvements upon the Ghanneling-Machineof Joseph B. Johnson, patented July 28, 1863, of which previously channeled in the old and usual way.

The nature of my invention consists in combinin g, with the tubular and angular cutters of the machine, certain devices for automatically laying back and pressing down the flap of the channel at the same time that the channel and groove are cut, thereby completing, at one operation, the channeling and preparing the soles ready for the sewing-machine. It also consists in constructing the plows as herein described.

As shown in the drawings, A is the head of the machine. B is a guide, attached to the 'head by means of screws b b, which pass throughy slotted holes in the guide, and allow of its adjustment. Projecting backward from the lower part of the guide a guard, C, is con structed, in the form shown, which enters into the space formed in the angular knife and plow, and serves to give direction to the fold of the flap as it is passed backward from the knives. D is the angular knife, which requires to be adjusted at the proper distance below the foot of the guide B, for producing the required thickness of the flap. E is the plow, having a peculiarly-curved surface, as shown, by means of which the turning back of the lap is completed. 4It has a recess formed in its face, into which is inserted the tubular knife'or groover F, for cutting the grooves for containing the stitches that secure the sole to vthe shoe. The groover upon its face is made to conform to the curved form of the face of the plow, and is retained in its position by the pin f. G G are bolts for securing to the head A the knife D and plow E, in both of which provision is made for their proper adjustment by means of the slotted holes g g. H is a roller, attached to the head of the machine by means of the bracket I. It stands directly behind the plow, and presses down the ap, after it has been turned back by the plow, in such a thorough manner as to prevent its being caught bywthe needle of the sewing-machine while attaching the sole to the shoe. j

This roller also serves as an upper feed-roller, thereby enabling me to dispense withthe roller usually placed upon the machine for that special purpose. The plow J, shown in Fig. 5, is made without a grooving-knife.V lt is substituted in the lmachine for the knife I) and plow E, and is intended to be used upon soles that have been channeled and grooved in the old and usual way, for turning back the flaps so as to pass under the roller H. It is provided with the projecting point K, which enters the groove for the purpose of removing the core left by the groover when previously channeled, as above stated, and at the same time it guides the sole in its proper direction.

By constructing the plow E with a detachable groover, F, as hereinbefore described, I am enabled to make them more perfectly than if made together; and it also has the further advantage of permitting the groover to be renewed at pleasure when it becomes defective from use, or any Aother cause, without involving the expense of renewing the plow.

The work accomplished by my improvement has heretofore been performed by hand after the soles have been channeled by the cha-nneling-machine, and for this work alone from four to ve operatives were required to open and lay back the work done by each channeling-machine. In this way the work was very imperfectly done, the soles being frequently injured by being indented by the hammer used for this purpose.

By the use of my improvement, it will be readil y seen that the same number of soles that eould only be channeled. and grooved by the nmeliine heretofore, can now be completed ready for the sewing-machine in 2t more pereci nimmer, in the saine time, and, by dispensing; with the services of the extra operatives, at a reduced cost.

l do not broadly claim the use of the an gular and tubular knives l'or the purpose of channeling the soles of shoes, as I am aware that they have heretofore been hnown mui useuior tnls purpose; but

What I cla-iin as my invention is- 1. The combination of the guide B, knife D, and groover F, with the plow E and roller H, when arranged to operate as and for the purpose speeitied.

2. The plow E having a detachable groover, F, constructed substantially in the manner and for the purpose specified.

3. The plow J having zt projecting point, K, as and for the purpose herein set forth.
