JOINTING-MACHINE.

Patented'Aug. 24, 1915.

Application filed August 27, 1910. Serial No. 579,241.

To all whom it may concern Be it known that I, JAMES CAVANAGH, a citizen of the United States, residing at Boston, in the county of Suffolk and State of f Massachusetts, have invented certain Improvements in Jointing-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 shaving along the edge of the shank begin-.

ning a short distance forward of the breast and extending back to the breast, the plane of the cut generally making an obtuse angle with the plane of the shank, and then severing the shaving by a cut in the plane of the heelbreast substantially at right angles to the previous cut. tion neatly and quickly requires considerable skill.

It is the object of this invention to provide means whereby an unskilled operator may perform this operation with ease and accuracy and to this end is provided a belt knife, driven at high speed from any suitable source of power and provided with the necessary guides and guards so that a shoe may be readily placed in such predetermined positions with relation to the knife that the cuts described as incident to the hand operation may be made with despatch and without the exercise of any particular skill or attention on the part of the operator.

One feature of the present invention consists in means for positioning and guiding a shoe transversely of the knife to raise a jointing shaving along the edge of the shank portion of the. sole. As shown the knife is arranged for movement in the direction of its edge .tofacilitate the cutting operation, and the guiding means is arranged at an 55 angle to the plane of the operating portion To perform this operaof the knife and is made adjustable to vary the angle between the edge and bottom faces of the shank portion of the shoe sole. Preferably two guides are provided, one for use in treating each side of the shank, and the guides may, as shown, be arranged for simultaneous adjustment. Guards to protect the upper from the action of the knife are provided which may have acting faces reversely inclined to the knife with relation to the guides.

Another feature of the invention consists in a member for positioning and guiding the shoe in front of the knife with its heel breast substantially parallel to the plane of the knife and with the plane of the tread face of the shank of a shoe at an angle to the knife edge, whereby the edge of the shank is presented to the knife. The positioning member is provided with two oppositely inclined faces making oblique angles with the knife edge against which the shank is positioned alternately when operating upon the two opposite edges of'the shank. Preferably the positioning means is mounted for movement toward the knife edge whereby the shoe is guided to bring the edge of the shankinto operative relation to the knife. As shown the movement of the positioning and guiding member is against a spring which comes into action during the latter part of the cutting operation and warns the operator by the increased resistance offered that the end of the cut is being reached so that he will exercise caution in completing the cut and avoid cutting too deeply. Means 1s also provided adjacent to the guiding surfaces of the member for preventing movement of the shoe in response to the drag of the knife caused by its movement in the direction of its edge, and this means also limits sliding movement of the shoe over the guiding surface.

Another feature of the invention consists in the combination of a knife and two means 100 adjacent to the knife for use alternatively in guiding the shoe during separate cuts for effecting a jointing operation upon the shoe. Suitable guards are provided for the knife which expose the knife edge at the operating 105 and the guiding and positioning means may I50 ing for a pin to be used-as a wrench in ad-' ljusting'the screw. Theblook'18 carries a- -2tl1b-Shaft'26, upon' whi ch is, the idler 28 beadjacent to the breast faceof the heel.

be located upon the same run of the knife, which run is preferably arranged in a horizontal plane. By one of the separate cuts made by the machine a shaving is raised,

along the shank portion of the shoe sole, the shaving being attached to the sole at a page e other out is made in the plane of the heel breast or parallel thereto to separate the shaving from the sole. By the machine of the present invention these separate cuts may be made upon either side of the shoe and in any order.

These and other features of the invention will appear from the following description when read in connection with the accompanying drawing which represents one embodiment thereof and will be pointed out in the appended claims.

In the drawings :Figure 1 of the drawings is a perspective view of an embodiment of the present invention; Fig. 2 represents the portion of a shoe operated upon by this device; Fig. 3 is a diagrammatic representation of the shoe and the operative parts of the jointing device for raising the shaving shown in Fig. 4. Fig. 4 is a representation of the shank portion of a shoe similar to Fig. 2 showing. the jointing shaving raised but not severed. Fig. 5 is a diagrammatic representation of the operation of severing the shaving.

As represented in Fig. 1, the numeral 1 designates the base of the machine upon the opposite ends of wh ch are standards carrying bearings for shafts 2. and 4, upon which are journaled wheels 6 and 8. About these wheels 6 and 8 passes a'belt knife 10 which is driven by a-pulley 12 on the shaft 2 driven from any suitable source of power by a belt 14. Between the wheels 6 and 8 is located a support 16 in the lower part of which is arranged a tension device for the belt knife, comprising a block 18 arranged for sliding adjustment in a slot 20 formed in the support 16 and held in position by a screw 22, threaded through block 18 and abutting against the support 16 at the top of slot 20. For convenience, the screw is provided with the thumb .nut 24,-which has the usual openzneathwhichthe belt knife passes. By this arrangement it isxobvious that thetension upon the belt "knifemay be regulated by ad- I justing the block 18fup.and down by means of'screw 22 and nut.24.

' Guard plates 30 and 32 are provided above the'baseof the machine to prevent any sha'vings or chip's-of leather from falling upon tical plane of the knifes path. The plate 30 extends from the upper edge of plate 32 obliquely upward under the upper run of the knife where it is fastened to the support 16 .to-cover the lower run of theknife,

- as may be seen best at the right-hand end of Fig. 1, and divert the chips away from the lower run. I

a The upper run of the belt knife passes cut is determined with the aid of mechanism now to be described and which is repreguard plate 36 secured to the support 16 is located above the knife and has portions cut away at 11, 11 to expose the knife 10. Upon this guard plate rests the upper guard 38 which, in order that the depth of cut may be varied, is adjustably secured by a screw 42 and a slot 44 to a yoke 46, secured to the main support 16. Also carried by the yoke 46 are sole resting and guiding plates'48 and 50 which. are held for adjustment about their lower edges by links52 connected to cars 54 on the underside of the plates and to a screw 56 which is threaded through a nut 58. This nut is held from vertical movement in the the plane of the shank. The course of this 7 sented in the left hand half of Fig. 1. The

support 16 and by rotating it the sole plates 48 and 50 may be simultaneously adjusted to various angles relatively to the knife 10. Adjacent to the plates 48 and '50 and beneath the same is located a stop 60 against which the breast of the heel abuts, when the jointing OlltIiS completed. l

The operation of the mechanism just described will be obvious froman inspection of F ig. f; in connection with Fig. 1. j

The shoe to be operated upon is..placed with its shank against the sole plate 48 and the shank edge against the portion of the knife between the base of the sole plate 48 and the upper guard 38, the knife edgebedistance from the breast of the heel. 'The shoe is now slid forward on the plate 48v While the knife 10 makes a cutalong the shank toward the heel breast, theoperation of the knife being limited by thebreast of the'heel comingin contact withtthe' s'top v60.

The shoe is now shifted, itsisliank placed in contact with the sole plate some the o eration repeated upon the other" side o the shankby sliding it against the portion ,of the belt knife between the base of 'the'sole plate 50 and the upper guard 40. Each'side vof the shoe is now in thecondition represented in Fig. 4 and it remains to remove the shavings now held to the shank on the opposite sides of the shoe by a portion of leather atthe point 5 of Fig. 4. This part of the operation is performed by mechanism to bedescribed.

Referring now to the right'hand side of Fig. 1, a continuation of the guard plate 36 attached to the support 16 projects forward over the knife covering the same except along its forward edge at 11 where it is cut away to expose a portion of the edge of the knife. Above the knife is a guide plate 68 which is supported for movement transversely of the knife. Upon the rear side of plate 68 is an upwardly turned flange which is secured to a rod 70 which passes through a-boss 72 extending from the rear side of the support 16. Within the boss 72 is a spring 74, the outer end of which rests against the boss and the inner against an enlargement 76 of the rod 70. By this means the plate 68 is forcedforward andresiliently held for back ward movement. The nut 7 8 upon the rod 70 forms an adjustable limiting stop for the forward movement of'the plate 68. The forward portion of the plate 68 is pointed to form guiding edges 82 and 84 which are preferably inclined to the knife edge at about the same angle that the plate 48 or 50 has to the plane of the knife, whereby the shank is positioned by said inclined edges substantially perpendicular tothe position in which it was guided by said plates 48, 50

. respectively and the shaving will be cut off clean.

- The mechanism just described 1s used for the removal of the shavings made by the previous operation. The shoe is placed with the breast of the heel resting against the under side of the plate 68, the support 16 being cut away to permit this presentation of the'heel under the knife 10, and with its shank resting against one of the forwardly inclined edges thereof, for example, the edge 82 preferably high enough on the inclined edge so that the shoe is out'of touch with the knife. At the rear ends the guide edges so- .soinewliat and as'the shoe slidinto this 82 and 84 are curved outwardly and forwardly to the points 83 and- 85. In these curve'd portions' the knife 10 is exposed curved portion the knife engages the shav- 7 ing vandcuts into it. Theshoeis then slid "not project forwar along this inclined edge until the portion of the knife exposed by the cut-away. portion of theknife guard 36 engages the shav ng and separates it. Afterthis the operation is repeated by sliding the shoe-along the other inclined edge 84 of guide68 unt lthe other shaving is detached by the knife in a similar manner. IfC,1 however, the knife does the shoe and guide transversely of.

. in the direction of travel of the knife.

far enough withrelation to the" guide to completely sever the 'jointing shaving, backward pressure upon theknife will move the guide plate against the spring 74 and allow action of the knife to the extent provided by the cut-away portion of the guard 36, thus insuring complete severance of the shaving. The curved or hooked portlons of the guide at 83 and 85 serve, moreover, to prevent displacement of the shoe The portions 83 and'85 engage about the edge of the shoe shank and prevent its following the drag of the moving knife. portions are provided upon both sides of the guard so that the knife may be driven in either direction. The guard plate 36 serves to support the guide 68 and to limit the depth of the cut made by the knife.

It will be noted that with the adjustment shown in Fig. 1 the initial cut for severing the shaving can be made without pressing back the guide 68. Preferably, however, the adjustment of the guide is such that the completion of the cut is effected only when pressure enough is applied to force the guide backward. By this arrangement the operator is warned, by the resistance of the guide, of the fact that the limit of the cut is being reached and he instinctively will then exercise the'caution needed to avoid cutting too deep. Moreover the increased pressure will serve to steady the shoe and will tend to insure that it is positioned squarely against the guide for making the cut at the angle for which the guide is designed.

It is, of course, obvious that either of the steps of the operation may be performed first; it may be found more convenient to make the cut in the plane of the heel breast first and then the jointing cut, the final result being the same in either case.

Other changes in manner of operation and in the design and arrangement of mechanical parts may be made without departing from the spirit of the invention.

The following claims are designed to define the invention but are to be construed as limited in scope only by the state of the prior art.
