ENSEAM-TRIMMING .IVIACHINE.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed April l6 1904. Serial 'No. 203,473.

To all whom, it may concern: I

Be it known that I, JOHN W. REILLEY, a citizen of the United States, residing at East Lynn, in the county of Essex and State of Massachusetts, have invented a new and useful Enseam-Trimming Machine; 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 invention relates to an enseam-trimming machine, and has for its object to provide a simple, inexpensive, and efiicient machine capable of rapidly and automatically trimming the seam formed by sewing the welt to the upper and to the inner sole.

A further object of the invention is to rovide a machine of this character adapte to trim or shave down the ridge formed by uniting the upper, the inner sole,-and the welt and to enable a smooth level surface to be produced for the reception of the outer sole without liability of injuring the stitches which connect the said parts.

The invention also has for its object to enable the cutting to be readily controlled to leave -sufficient material for the firm and secure attachment of the outer sole.

l Vith these and other objects in view the invention consists in the novel construction and arrangement of parts hereinafter de scribed and shown, and particularly pointed out in the appended claims.

In the drawings forming part of this specification, and in which like numerals of reference designate corresponding parts, Figure 1 is a plan view of an enseam-trimming machine constructed in accordance with this in-. vention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse sectional view. Fig. 4 is an enlarged detail sectional View illustrating the manner of adjustably mounting the guide-wheel. Fig. 5 is a detail view illustrating the manner of reci rocating the knife. Fig. 6 is a detail view illhstrating the manner of mounting the shoes on the rotary carriage.

Referring to the drawings, 1 designates a main frame which may be constructed in any suitable manner and which is provided at one side with suitable bearings for a vertical shaft 2, having fixed to its upper end a rotary table or carrier preferablyin the form of a circular frame and adapted to receive the boots and shoes to be trimmed, it being understood that in the use of the term shoe boots, slippers, and the like are contemplated. The rotary carrier is provided adjacent to its periphery with an approximately circular slot or opening 4, in which is adjustably arranged front and rear supports 5 and 6, and the latter project upwardly from the carrier, as clearly shown 1n the drawings. The rotary carrier is provided with a diametrically-arranged bar forming radial spokes or bars 4 and support: ing the outer portion or periphery of the carrier. The front and rear supports 5 and 6 are adapted to receive and support a shoe and its last, the front support being provided with a shank 7, adapted to fit in an opening or socket 8 of the last. The rear support is provided at the top with a concave part 9 to receive the last, which is arranged ina slightly inclined position, as shown, and which is capable of adjustment by moving the rear support backward or forward. The supports 5 and 6 are firmly clamped to the rotary carrier by means of horizontal clamping-screws 10, mounted in suitable perforations and piercing the outer ortion of the frame of the carrier and exten ing to and arranged to engage those portions of the su plorts 5 and 6 which are arranged within t e s 0t.

The rotary carrier may be of any desired size to produce a machine of the desired capacity, and in practice the heel of one shoe will be contiguous to the toe of the adjacent shoe, there being no intervening space between the shoes whereby the knife, hereinafter described, is prevented from dropping and accidentally injuring any of the shoes. The knife 11for trimming theenseam is provided with a pair of cutting portions, and it is mounted for reciprocation in a vertically adjustable or movable frame 12 of approximately rectangular shape, having depending arms '13 provided with guide-openings receiving the end portions of the knife 1 1. The frame, which carries the knife, besides being vertically movable, is pivoted to swing in a horizontal plane by a vertical rod 14to a post 15, which is provided with vertically-alined bearings or ears 16 to receive the pintle-rod. The ears 16 are mounted in slightly-elongated slots in the post 15, which permit a limited vertical movement of the knife-car rying frame.

Y The knife-carrying frame has laterally-extending arms 17 and 18, which are perforated by the said pintle-rod 14. The upper arm 17 is provided at opposite sides with notches arranged to be engaged by pivoted dogs 20, mounted on the upper ear or bearing 16 and arranged to engage the'said notches for adjustably holding the knife-carrying frame in its horizontal carrying frame is horizontally adjustable on its vertical pivot to enable it to be arranged properly with relation to the lasts of the rotary carrier. The lasts, which in practice may be of various styles and shapes, are set at an inclination to insure a positive cutting operation. The frame 12 by being mounted on the vertical pivot-rod 14 is capable of the said adjustment, and it is secured in its adjusted position by the said dogs 20.

The knife is arranged to engage a shoe at opposite sides for trimming the enseam, as before explained, and it is prevented from cutting too deep into the material by means of a combined guide and gage wheel 21, arranged to run on the sho es and mounted in a slot or bifurcation of a standard 22, which is secured at its upper end to a bar or arm 23. The bar or arm 23 is mounted in suitable guide-slot 24 of the knife-carrying frame and is secured in its adjustment by a suitable fastening device 25, consisting of a wedgeshaped pin or the like. The knife-carrying frame moves upward and, downward to the action of the guide-wheel as the same runs along the shoes, and the latter are trimmed as rapidly as the shoes can be applied to and removed from the rotary carrier. When the knife carrying frame is properly adjusted and the guide-wheel properly set, the machine in its trimming operation is entirely automatic.

Mounted on the lower portion of the vertical shaft 2 is a horizontal gear-wheel 26, which meshes with a vertical gear 27 of a horizontal shaft 28. The horizontal shaft 28, which is journaled in suitable bearings, has keyed or otherwise fixed to it a pulley 29, which is connected by a pinion 30 with a pulley 31 of a shaft 32'. The shaft 32, which is provided with a drive-pulley 33, has a third ulley 34, which is connected by a belt 35 with a pulley 36, and the latter is provided at its outer side with a wrist-pin 37 and is connected by a pitman 38 with'one arm of an L- shaped lever 39. The L-shaped lever 39, which is fulcrumed on a suitable support, is loosely pivoted to the adjacent end of the knife, w 'ch permits a limited vertical movement thereof and is adapted to reciprocate the-same. I Bythis arrangement ofthe gearposition. The knifeing the rotary carrier is operated to carry the shoes beneath the knife, and the latter is reciprocated to trim the shoes.

I desire it to be understood that various changes in the form, proportion, and minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim is- 1. In a machine of the class described, the combination with cutting means, of a carrier having a plurality of shoe-supports arranged to present the enseam to the cutting means, substantially as described. v

2. In a machine of the class described, the combination with cutting means, of a carrier having a plurality of shoe-supports arranged to present the enseam to the cutting means, and guiding means for limiting the depth of the cut, substantially as described.
