ROUGH-ROUNDING AND CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 625,633, dated May 23, 1899. Application filed April 9, 1895. Serial No. 545,115. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK L. ALLEY, a citizen of the United States, residing at Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a new and use-' ful Improvement in Rough -Rounding and Channeling Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

The object of the present invention is to provide in machines of the above class means whereby the same are adapted to operate upon the soles of shoes finished with an edge of varying width-such, for example, as that commonly termed a Scotch or Baltimore or an extension edge-and Isecure the abovesuggested results by means of a single gage arranged to perform the double function of a stationary and movable gage, as hereinafter more specifically set forth and claimed.

This invention as applied to the machine shown and described in United States Letters Patent to H. Briggs, No. 463,967, dated November 24, 1891, and to Briggs and Dancel, No. 511,263, dated December 19, 1893, is illustrated in the accompanying drawings, in which- Figures 1 and 2 are respectively aside elevation and top plan view of the machine shown and described in said Letters Patent, showing my invention as applied thereto. is an enlarged plan View, partially in section, showing my improved work-gage and a portionof its operating mechanism. Fig. 4 is a section on line X X, Fig. 3; and Fig. 5 is a longitudinal vertical section through the work-gage.

Similar letters and figures of reference refer to similar parts throughout the several views.

In the drawings, 1 represents a suitable bed-plate upon which the working parts of the machine are mounted and which may be con- I ble 2, a four-motion feed 3, a feed-clamp 4,

pivoted on the shaft 5, a vibrating channeling-knife 6, an oscillating rough -rounding knife 7, and the power-shaft 8, carrying the cams 9, 10, and 11 by which the working parts are actuated, all of which, together with their connecting mechanisms, are fully shown and described in the Letters Patent before cited and form no part of the present invention.

The reference-letter b represents the throatplate',which is pivotally mounted upon a shaft 15 in line with the shaft 5, and is provided with a socket 12, which is engaged by a pin 13 on the feed-clamp 4:, the arrangement being such that the plate I) has a' verticallyswinging motion with the feed-clampet for the purposes setforthin said Letters Patent. The throat --plate. I) is provided with a cuttingthroat bZinwhich works the oscillating rounding-knife 7, making the cut substantially as shown and described in'said Letters Patent.

The reference-letter 1) represents the movable gage, which in the form of my invention shown in the drawings is also pivotally mounted upon the shaft 15, and, as shown, has a vertically-swinging movement with the plate I) about shaft 15 as an axis. The gage b is movable longitudinally along the throat-plate b, and provision is made for such motion in the pivotal connection between the gage b and shaft 15 conveniently as follows: To the gage b is rigidly secured a link 16, arranged to slidealong a block 17, which guides the longitudinal motion of link 16 and is mounted upon shaft 15, aboutwhich it is free to rotate. The block 17 is rigidly connected to or made intogral with a plate 18, mounted upon the shaft 15 and free to rotate with the block 17 thereon. The plate 18 is rigidly connected by a bracket 40 with the throat-plate b. A plate 48 is secured'to the outside of block 17 and, with the plate 18, holds the link'16 laterally in position.

The gage b is conveniently provided with the horizontal extensions or gibs 19 19, which embrace the throat-platelb, the above-described arrangement being such that the gage b is swung vertically by the vertical swinging movement of throat-plate b as imparted thereto from the clamp 4, and at the same time the gage b is free to move longitudinally along the throat-plate b for the purposes hereinafter described.

In said patented machine the outer end of the throat-plate was arranged to form a stationary gage, against which the shoe was held and which determined its inward position. In my present invention I have dispensed with an independent stationary gage, as above proposed, and have so arranged the movable gage that it controls the position of the shoe during the entire operation of the machine, engaging the same in its outward and inward and all intermediate positions, as hereinafter described.

In the form of my invention shown in the drawings I have secured the above-described result by extending the outer end I) of the gage Z) across the outer end of the throatplate I), which is preferably cut off adjacent to its throat b the end 11 forming a longitudinal extension thereof. As shown in the drawings, the end I) of the gage b is shaped and held in position to enter the crease between the upper and welt and bear upon the inseam; but I do not desire to limitthe present invention to such construction, as it is evident to one skilled in the art that the gage may be formed and arranged to bear upon the last without involving any departure from the present invention.

It will be understood from the foregoing description that the gage l) is movable independently of the throat-plate and feed transversely to the direction of the feed to move the shoe toward and from the rounding-knife, and to actuate the gage during the operation of the machine I have adopted the following as being a convenient form of mechanism.

. 21 and held in position by the collar 23.

To the bed-plate 1 is secured a bracket 20, which carries a vertical sleeve 21, preferably rigidly secured thereto. Through the sleeve 21 extends arod 22,'free to rotatein said sleeve Near the upper end of the rod 22 is' secured a laterally-projecting arm 24, which is pivotally connected with the connecting-rod 25, which is pivotally connected with the link 16 on the gage b of the gage B. In practice I find it preferable to secure the arm 24 upon the rod 22 by means of a collar 26, preferably integral with arm 24 and held in position upon the rod 22 by a set-screw 27, by means of which the lateral inclination of the arm 24 may be regulated. The rod 22 is conveniently vention shown in the drawings is necessarily used only to rotate rod 22 in one direction, rotation in the opposite direction beingimparted thereto by means of a suitably placed spring 28. The spring 28 may conveniently consist of a coiled spring coiled about the rod 23 and having'one end secured to the sleeve 21 and the other to the rod 22 or a suitable collar 29, rigidly mounted on said rod.

The extent of the rotation of rod 22 and the angular mot-ion of the arm 24 may be conveniently limited by the following device: The collar 23 carries a horizontally-projecting arm 30, which turns alongaflange 31 on the sleeve 21. The flange 31 is provided with the projecting lugs 32 34, which project in the path of the arm 30 and which limit its swinging motion. The extent of the swinging motion of arm 30 permitted by lugs 32 34 may conveniently be rendered adjustable by means of thead j ustm ent-screw 33,which has athreaded bearing in the lug 34 and is arranged to come in contact with the arm 30 as it approaches said lug. The spring 28 acts to hold the arm 30 in contact with the lug 32, and when in such position the relative inclination of the arms 30 and 24 is such that the gage b is held substantially in the position shown in Fig. 3, with its outer end 1) against the outer end of the throat-plate b.

The operation of my invention as adapted to the machine shown in the drawings is described as follows: The parts being in the position shown in Fig. 3, in which they are held by the action of spring 28, the feed-clamp 4 is raised by its operating-lever raising the throat-plate Z) and gage b by means of the pin 13. A shoe is then placed upon the work-supporting table 2 with the projecting edge of its sole between the feed 3 and the clamp 4, and the clamp 4, with the gage I), brought down thereon and the machine set' in operation. As the shoe is fed along and rough-rounded and channeled by the channeling and roughrounding knives it is held by the operator against the gage Z), which, as hereinbefore described, bears against the inseam and determines the position of the path of the knives relative thereto. When a place upon the shoe is reached where it is desirable to widen the edge left upon the outsole',the operator presses outward with his knee upon the lever 37, and thereby rotates the rod 22 against the tension of the spring 28, moving the arm 30 toward' the lug 34 and advancing the arm 24, which, by means of the, connecting-rod 25, slides the link 16 along the block 17, moving the gage b along the throat-plate b, and thereby moving outward the end b of the gage b, which bears against the inseam. This outward motion of the gage b forces the inseam farther from the cutting-path of the rough-rounding knife 7, and said knife cutting farther from the inseam leaves a wider portion of the sole projecting beyond the samethat is, widens the'edge at that point. If, as in the machine of the drawings, the relative position of the channeling and rough-rounding knives remains unchanged, then when the edge is widened, as above explained, the channel will be cut a corresponding distance farther from the center.

By means of the set-screw 33 the limit of the out motion of the gage b is determined, and consequently the limit of increase that can be made in the width of the edge. By means of lever 37 the change in the width of, the edge may be made gradually or abruptly, as the operator may desire. As the operator releases the lever 37 the gage 11 returns to its original position,and the original width of the edge of the outsole is again secured by the operation of the rounding-knife.

Having thus described my invention and its mode of operation, I desire to say that the same is clearly distinguishable from any device involving the combination of independent movable and stationary guides, and that such construct-ion forms no part of the present invention. I, however, do not consider the present invention as limited to the details of mechanism herein shown and described; but

I claim as novel and desire to secure by Letters Patent 1. In arough-rounding and channeling ma chine, the combination with the throat-plate, of a movable gage forming an independentlyadjustable longitudinal extension thereof, substantially as described.

2. In a rough-rounding and channeling machine, the combination with the throat-plate, of a movable gage forming an independentlyadjustable longitudinal extension thereof, and means for actuating said gage, substantially as described.

3. In a rouglrrounding and channeling machine, the combination with the throat-plate, of a movable gage forming an independentlyadjustable longitudinal extension thereof, and an operatinglever and suitable connections for actuating the gage, substantially as .eration of the machine, and movable in one direction with and in another direction independently of the feed mechanism, substan tially as described.

5. In a machine for operating on the soles of boots and shoes, the combination with a suitable feed mechanism, of a single gage shaped and held in position to enter the crease between the welt and the upper, arranged to guide the shoe during the entire operation of the machine and movable in one direction with and in another direction independently of the feed mechanism, substantially as described.

6. In a machine for operating upon the soles of boots and shoes, the combination with the rounding and channeling knives, of a single movable gage arranged to engage the crease between the upper and the welt to guide the shoe during the entire operation of the machine, and means under the control of the operator to move said gage transversely to the direction of the feed of the work during the operation of the machine to vary the position of the cut made by said knives, substantially as described.

In testimony whereof I have hereunto set my hand,this 3d day of April,1895, in the pres ence of two attesting witnesses.

FREDERICK L; ALLEY.
