JOHN B. HADAWAY, or SWAIVIPSCOTT, MASSACHITSETTS, AssIeNoR To UNITED SHOE MACHINERY COMPANY, or PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.
LEATHER-CUTTING MACHINE.
To all whom it may concern:
Be it known that I, JOHN B. HADAWAY, a citizen of the United 'States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Leather-Cutting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invent-ion relates to apparatus for the treatment of material such as leather, and is of special utility when embodied in a machine for scarfing sole leather in the production of taps used for repairing shoes, although I contemplate the use of my improvements in any field for which they may be adapted by their nature.
An important object of my invention is to provide a pair of cooperating cutting members and a support for the material to be treated so constructed and arranged as to permit adjustment of these instrumentalities in different angular positions to effect a scarfing cut of the inclination desired in any particular instance by the positive shearing action of the cutters, the support preferably serving primarily as means to present the material firmly to receive the scarfing stroke.
Another important object of my invention is to support the cutter or cutters so that they may be turned readily from the angular position for a scarfing stroke to the position for perpendicular severance, or cutting 01? of the material, which may involve a change of approximately 90 at times, and which, in accordance with my improvements, may be accomplished manually and freely by the operator without taking his hands from the material and the shear handle respectively.
In the preferred embodiment of my invention, I provide a stationary base having a substantially horizontal supporting table for the sole leather forming the tap stock, or for such other material as is to be treated, and I mount on pivot bearings near the ends of this table a frame rotatable about an axis which coincides as nearly as possible with the delivery edge of the supporting table, this frame carrying a pair of cooperating cutting members, such as a pair of shears, of which one may be fixed onthe frame with its edge adjusted to the axis, and the other specification of Letters Patent. Application filed March 8, 1910.
Patented Dec. 30, 191-3. Serial No. 547,955.
shear is mounted on a ing carried by the frame near one end. Thus, when the operator has grasped the handle of the pivoted shear with one hand and the tap with the other, he can swing the frame around to the proper angle, scarf the tap to give it the desiredinclination, and then Without removing his hands can swing around the frame into position for a vertical cut and trim the ta to give it a true edge.
Among other ob ects of my invention may be mentioned the provision of means to hold the frame in selected angular position; also means to aid the operator in holding the stock steadily in position for treatment.
The various features of my invention will be illustrated and described fully in the accompanying drawings and specification and pointed out in the claims.
In the drawings, Figure 1 is a view in perspective of a tap scarfer in the construction of which my improvements have been embodied; Fig. 2 is a similar view showing the operating parts in a different position relatively to each other; and Fig. 3 is a sectional view taken on the vertical plane 00 -41 Fig. 2, looking from left to right.
Inthe embodiment of my invention selected for illustration and description to enable ready and complete understanding of my improvements, the part designatedby the reference numeral 1 is one of the cutting members, 2 is a cooperating cutting member and 3 is the support forthe material 4, (see Fig. 3) shown as a tap of sole leather. These parts may be of any suitable construction and arrangement to secure the desired relative angular adjustment between the support and cutters. In the instance illustrated the support 3 takesthe form of a table cast integrally with a base 6, and the cutting mem-' bers 1 and 2 are movable relatively thereto, being mounted for that purpose on a frame 7, rotatable on pivots 8 and 9 supported in bearing lugs 10 and 11 extending up from the support 3 near each end of the table.
desired, suitable means may be provided to hold the frame 7 at any selected angle, as, for example, the key 12 with threaded bar-' rel 13 to be engaged with a threaded end 14 of the pivot 9 VJ hen the key 12 is run home, its barrel 13 engages the arm 15 of the frame 7 and crowds the arm against a collar 16 interposed between the arm 15 and the lug l1,
transverse pivot bearthus locking the frame frictionally against displacement from the selected position. Ordinarily it will be unnecessary to use such locking means, and the key 12 may e left relatively loose until needed. A split ring 120 may be provided to serve normally as a frictionally acting form of means to hold the frame 7 against displacement by gravity, or accident, from selected angular position.
The shear members 1 and 2 may be connected with the frame 7 in any suitable manner, and as one convenient form of mount for the movable shear 1, I have shown a transverse pivot bearing bolt 17 with retaining nuts 170, the bolt passing through the frame 7 at 18, and extending into position to receive the yoke 19 of a lever arm 20, to which the shear 1 is secured in adjusted position by suitable means, as the bolts 21, the lever having an operating handle 22, by which the operator can work the shear and can also rotate the frame 7 on its pivots 8 and 9. Stops 23 and 2 1 may be provided to limit the stroke of the cutter 1.
The frame 7 will preferably have a body portion 25 offset upon arms 15 and 150 to clear the delivery edge 33 of the supporting table 3, and to leave ample room for adjustment of the shear 2, the cutting edge 26 of which should stand closely adjacent to the axis of the pivots 8, 9, so that as the frame rotates the cutting edges of the shears 1 and 2 will operate as near as possible to the delivery edge 33, whatever may be the angular relation of the shears 1 and 2 to the table 3 (see Fig. 3). The shear 2 may be secured to the frame 7 by any suitable fastening means, such as the cap screws 27, and abutment screws 28 may serve also as one form of auxiliary devices to hold the shear 2 up to its work.
In order to present an uninterrupted surface for support of the work, I have shown the shear as set flush with the face of the body portion 25 of the frame, which is cut away leaving a ledge 30 to receive the shear 2, the latter having preferably slots 31 for the heads of the cap screws so that the latter will not project above the shear 2.
Suitable means may be provided to aid the operator to hold the work steady upon the supporting table, as for example a series of serrations 32 formed by milling the surface of the table near the delivery edge. The rear edge of the supporting table may be cut away, as at 34:, to give the finger or thumb of the operator access to the under side of the workpiece somewhat nearer to the cutting edge than would be convenient otherwise.
Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. Apparatus for treating material of the class described, said apparatus comprising a pair of cooperating cutting members; a support for material to be treated arranged to present said material for action thereupon by said cutting members; and means to vary the angular position of said support and cutting members about an axis which lies approximately in the plane of the support.
