IMPROVED MACHlNE FOR TRIMMING THE EDGES 0F BOOTS AND SHOES.

Speciiication forming 'part of Letters'Pa'tent No. 80,828, dated August ll, 1868.`

To all whom it may concern:

Be it known that I, RICHARD C. LAMBRT, of Raynham, in the county of Bristol and State of Massachusetts, have invented a new and useful Machine for Trimming or Paring and Smoothing or Beading the Edge of a Shoe or Boot; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure I is a topv view, Fig. 2 a front eleva tion, and Figs. 3 and 4 are vertical sections, of it.

In such drawings, A denotes the frame of the machine, the inner face of each side c a being grooved in manner as represented at b b in Figs. 3 and 4. These grooves are to receive the supporting rollers or wheels o c and d d of a jack or carriage, B, such wheels being arranged on it in manner as represented in Fig. 5, which is atop view of such carriage or jack as separate from the frameA. An clon gated gear is affixed to the carriage and jack, and engages with a circular gear, D, supported by a vibrating lever, E, and made to engage with a pinion, F, arranged upon such lever and upon a cranked shaft, G. A spring, e, acting against the rear arm of the lever E, operates to keep the gear D in engagement with the elongated gear G while the two are in movement. j

Within the carriage B is a sole rest and pattern, f, which is to support the sole of a shoe, S, during the operation of paring such sole, and is to serve as a pattern to guide the paring-cutter while in operation. The shoe is forced against the sole-rest by means of two screw clamps or pressers, H I, arranged within the carriage or jack in manner as represented. The -clamp I-I consists of a rotary nut, g, and a stationary screw, h. The clamp I consists of a saddle, 7c, and a rotary screw, Z, the latter being screwed into the part m of the jack. By revolving the cranked shaft G vertical, endwise, and rotary movements will be im,- parted to the jack.

Each end part of the elongated gear C is a circular segment. When either of these segmental portions comes into operation with the gear D, two cylindrical bolts, a a, are shot into corresponding recesses, o o, made in the journals of the wheels of the'jaek, there being such a recess in the journal of each of the Wheels of the jack. These bolts, while in either pair of recesses, prevent the journals thereof from having any lateral motion eX- cepting that of revolving on their axes. The bolts at proper periods are shot forward by springs p p, rections and held out of action with. the jack by means of two cam-bars, qq, xed to the jack and operating against sliders r r, supported within the frame A, and connected with the bolts by screws s s. The said bolts, with their springs, are arranged in cases t t, fixed to the frame A.

A bent lever, K, so pivotcd to a standard, a, erected on the frame A, as to be capable of being swung or vibrated horizontally, has a spring, o, applied to its shorter arm and iixed to the said standard, the spring operating to force the longer arm ofthe lever in a direc tion toward the gear D. Within the said longer arm-that is, within a space, w, formed therein-another or hand lever, L, is arranged, and is fastened at its rear end to the arm, so as to be capable of being moved vertically. The lever L is jointed to a slide-rod, M, so applied to the lever K as to be capable of playing vertically within it. The said rod proj cci's upward from a cutter-head carrier or frame, N, which carries a paring-knife, x, anda gage or guide, y, and it may also have applied lto it a tool or device for either smoothing or smooth ing and creasing the sole-edge. The guide or gage y runs between the sole and the uppei leather of the shoe, and, by being pressed against the sole, keeps the paring-knife from cutting into the upper-leather. The cutter frame or head N rests directly upon the pe riphery of the pattern f, which gages the depth of cut of the knife w, and causes it to cut in accordance with the pattern.

The back part of the heel of the solel is not pared by the machine, as the attendant, while the back part, a', of the jack may be revolving under the cutter, should keep the lever L raised', so as to prevent the guide y from running in contact with the part c'.

With the said machine a sole, when sewed or secured to the upper of a sh e, may have its edge pared. and smoother or pared,

and are moved in the opposite dismoothed, and creased, with great facility and y, a paring-knife, m, or the same and another accuracy. tool or implement for smoothing o1" finishing I claimthe edge of a sole of a shoe. The combination of the jack or shoe-holding x 'carriage B, the pattern, the stop-boltsn n, and RICHARD (1' LAMBERT the cutter-carrier N, provided With mechan- Witnesses: ism for operating them, substantially as speci- R.
