JOHN B. HADAWVAY, OF BROCKTON, MASSACHUSETTS.

SHOE-SEWING AND WELT-BEVELING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 579,146, dated March 23, 1897.

Application filed August 5, 1896.

To all whom, it 111,0,7 concern: a

Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residing at Broelo ton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Sewin g and Welt-Beveling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to shoe-sewing machines and more particularly to such machines having welt-beveling cutters arranged to bevel the welt of a shoe during the operation of sewing on the outer sole, such as disclosed in Letters Patent of the United States issued to me November 5, 1895, and numbered 549,125 and 5e9,124, respectively.

In the machines of the patents above referred to the welt-beveling attachments were carried by and dependent for their operation upon parts of the stitch-forming mechanism with which they were combined.

In the machine of Patent No. 549,124 the .Welt-beveling cutter is mounted upon and actuated bythe slide carrying the awl as the same is retracted preparatory to puncturing the Work for a new stitch, and upon the said retraction thereof the cut-ting of a portion of the welt is performed.

In the machine of Patent No. 549,125 the welt-beveling cutter is mounted upon the work-support, and upon a movement of the aWl laterally while in the work to feed the same past the needle during the sewing operation it acts to force the Work against the cutting edge of the knife, thus beveling a section of the welt substantially corresponding to or slightly greater than the length of the feed.

The constructions contained in the patents above referred to, while giving good results in operation and enabling the welt to be beveled during the stitching operation instead of beveling the same by hand or by a separate machine after the sewing had been completed, as was the practice prior to my inventions, are open to the objection that additional stress and strain are put upon the work-feeding mechanism by the necessity of carrying and Serial No. 601,772. (No model.)

actuating the Welt-beveling mechanism or the machine liable to get out of order and to wear out more or less in a shorter time than before the welt-beveling mechanisms were added thereto.

The objects of the present invention are to remove the objections above noted and to generally improve the construction and operation of the machine and to produce a combined shoe -sewing and welt-beveling machine in which the work-feeding mechanism and Welt-beveling mechanism shall be entirely independent of each other.

To this end the present invention consists of a combined shoe-sewin g and welt-beveling machine in which the welt-beveling mechanism is distinct from and derives its movements entirely independently of the workfeeding mechanism; and it further consists of the devices and combination of devices which will be hereinafter pointed out and claimed.

I have illustrated myinvention as embodying the stitchforming and work -'feeding mechanism substantiallyas shown in my patents above referred to, and such stitch-forming mechanism may be that of the Goodyear sole-stitching machine, which is the subjectmatter of Letters Patent of the United States No. 473,870, issued to the Goodyear Shoe Machinery Company as the assignce of Zachary T. French and William 0. Meyer, dated April 26, 1892, or any other suitable shoe-sewing machine with which my welt-beveling mechanism is adapted to be combined.

The present invention is illustrated in the accompanying drawings, in which similar letters refer to similar parts throughout the sev eral views, and in which- Figure 1 shows a plan of a portion of a shoesewing machine with the welt-beveling mechanism applied thereto. Fig. 2 is a side view thereof, looking toward the right in Fig. 1. Fig. 3 is a front elevation, parts being in section. Figs. "1h, 5, and 6 are respectively a plan, a front elevation, and an end view of the carrier for the welt-bevelin g knife. Figs. 7, S, and 9 are respectively a plan, a front guard k.

elevation, and an end view of the bracket and guide for the knife carrier. Figs. 10, 11, 12, and 13 are respectively a top plan, an inverted plan, a front elevation, and a side elevation of the knife; and Figs. 14 and 15 are respectivelyafront elevation and an inverted plan of the presser-foot.

In the machine of the drawings, B is the feed-slide, having at one end the upright stand 13, which carries in its upper end a stud upon which is loosely mounted the awl-carrying segment a, to which is secured the awl a A is a portion of the fixed frame of the head of the machine, in which is set the fixed stud 1'), upon which is loosely mounted the needle-segment I), having secured thereto the curved and hooked needle 11 and also there is mounted 011 said stud the needle-guard b.

The presser-foot lever e is mounted upon a pivot set in some fixed portion of the machine and operated as in the Goodyear machine hereinbefore referred to and has secured to its end the presser-foot 6 as shown.

To the frame A is secured the worlcsupport d, the upper surface of the forward end of which is cut away at d, as in the machine shown in Patent No. 549,124, before referred to, to accommodate the welt-beveling knife.

D represents a stand mounted upon and extending from frame A in which is formed a bearing D for the shuttle-driver D A represents a portion of the main shaft, and E a cam thereon, all of which parts, except as hereinafter noted, may be and conveniently are of the construction of similar parts in the said Goodyear machine.

0 represents a suitable bracket which supports and guides the welt-beveling mechanism and which is secured to the stand D, adjacent to the bearing D, by any suitable means, such as the screws 0. The bracket 0 is provided with a suitable supporting and guiding device for the knife-carrier. In the machine of the drawings this supporting and guiding device consists of the parallel rods or bars a, secured to and projecting from the base of bracket 0.

H represents a knife-carrier comprising the block h, having the smooth bearings h, adapted to fit and be reciprocated upon the guide .rods or bars a, and which at its inner front end is provided with the bent arm 72?, to the end of which is secured the knife 7c and knife- The end of arm 712 is provided with the horizontally and vertically disposed ribs or bosses 7L3 7%, which take into corresponding recesses in the rear faces of the shanks of the knife and knife-guard 7.: and k, which are secured thereto by the screws R the ribs and recesses insuring a correct positioning and secure fastening of the knife and knife-guard to the arm 712. The arm h extends outward and forward, as shown in Fig. 1, in such a position that the knife and knife-guard will be reciprocated back and forth within the cut-away portion d of the work-support d.

-m a short shaft f upon which is pivoted the lever G. The lever G is provided with the bearings g, which are fitted to the ends of the shaft f, upon which it is free to oscillate.

The lower end of lever G is forked or recessed at p, as shown in dotted lines, Fig. 3, and embraces a block or roll q, mounted upon a stud 0" upon the backof block 71. of the knifecarrier H, and the upper end of said lever is inclined, as shown, and is provided with a stud 25, upon which is an antifriction-roll t, which rests against and is acted upon by the face of cam E. A spring a, secured at one end to a stud n and at the other end to a stud n upon the upper end of lever G, tends to hold the roll t in contact with the face of cam E.

The above-suggested arrangement is such that upon a revolution of shaft A and cam E the face of said cam, acting upon the roll t, will impart an oscillating movement to lever G and through the connection of lever G with carrier H cause a reciprocation of said carrier and the knife 7c, mounted on the arm h thereof, thus causing said knife to bevel a section of the edge of the welt at each rotation of cam E as the sewing operation which unites the sole to the welt proceeds.

The operation of the stitch-forming and work-feeding mechanism of my machine is the same as that in the machines of the patents hereinbefore referred to and need not be specifically described herein, inasmuch as in my invention the welt-beveling mechanism is operated entirely independently thereof.

It will be noted that the bottom face of the presser-foot e is provided with a series of teeth or serrations e for the purpose of insuring a more positive holding of the edge of the sole and welt during the operation of the machine.

It will be noted that in the present invention the welt-beveling mechanism, being distinct from and deriving its movements entirely independently of the work feeding mechanism, the parts of the work-feeding mechanism are relieved from the extra stress and wear which resulted from mounting the welt beveling cutters upon and actuating them by the work-feedin g mechanism or from an arrangement in which the work-beveling cutter is stationary and the work forced against the same by the feed to make the cut.

Having fully described my invention and its mode of operation, I claim as new and desire to protect by Letters Patent of the United States 1. In a shoe-sewing machine, the combination with the stitch-forming and work-feeding mechanism, of welt-beveling mechanism actuated independently of the work-feeding mechanism, substantially as described.

2. The combination, with shoe sewing an v mechanism, of \velt-beveling mechanism comprising a carrier, a knife-carrying arm projecting therefrom, a suitable support and guide for said carrier and means to actuate the same, substantially as described.
