IMPROVEMENT IN CHANNEL OPENERS AND MOLDERS FOR BOOTS AND SHOES..

Specication forming part of Letters Patent N o. 168,045, dated September 21, 1875; application filed July e9, 18754.

To all whom it may concern:

Be it known that l, THOMAS L. MILLER, of the city and county ot' Philadelphia, in the State of Pennsylvania, have inventeda Gombined Channel Opener andMolderof Shoe- Soles, of which the following is a specification: Y

My invent-ion consists mainly in the combination of a revolving channel-opener with a wheel having a square edge, which revolves in apl-ane at right angles to that ofthe opener, for forming the marginal surface outside of the channel, a like wheel, having a square edge, revolving in a plane' at right angles to the latter wheel, for guiding the edge of the sole, thereby regulating the Width ofsaid marginal surface, and gaging the distance ofthe channel from the edge of the sole 5 and a wheel with a round edge revolving in a plane at right angles to the-said gage-wheel, which presses toward the channel-opener, and the wheel which l'orms the marginaly surface for bending the sole, as hereinafterfully described.l

The channel-opener is on one end of a rod, which is situated in the bore of a revolving shaft, which also contains a wire spring, which forces the channel-opener forward after the operation of opening'the channel and molding the sole, and the bending wheel has been thrown outward from the solethereby relieving the sole from its connectionwith all the wheels, to be' readily removed from the channel-opener, the throwing back ofthe said bending-wheel heilig eifected by the movement of a lever, with which the shaft of the said wheel is connected.

In the accompanying drawings, Figure l is a plan view of the combined channel opener and iuolder. Fig. 2 is a side elevation of the saine. Fig. 3 is a longitudinal 'section of the sole F. l

Like letters of reference in all the figures iudica-te the same parts.

A is a stand, with which the several part-s i ofthe machine are connected. Its uprights a a are slotted to receive th`e bearings ofthe horizontal revolving' shafts B B1 B2. U is a revolving channel-oponer on the outer end of the stein D, situated in the bore d ofthe shaft B. E is a wheel on the vertical stud-shaft B3, whose projecting edge f bears against the sole k, whichpasses through the cheeks l l ofthe stand'A. .This wheel has a rounded edge for molding the part m of the sole. The lever J" Y is adjustable, by means of the nut K, on the upper end of the rod L, which projects upwardl rom the top of thestandard A, whereby to vary the dist-ance'between the periphery of the wheel I an'dthat of the wheel E, to regulate the thickness of the sole at its edge. M is a springfwhich surrounds the' rod l, and bears the free end of the lever upward against the nut, but yields' sufficiently to the reaction of the sole, to prevent a too compact condensation of the same. l

The shaft B2, which inthe present arrangement of thegearing is the driving-shaft, has a band-wheel, N, which connects by means of the band O withl the Wheel N on the shaft B, A

for revolving the'chanuel-opener C.

Motion is communicated from the driving; shaft B2 to the shaft B1, by means ofthe spurwheels P and P on saidshafts, respectively, to revolve the gage-wheel'H, which in its revolutions revolves the wheel E, by its inner side, at the periphery of the wheel, bearing against the peripheral surface of the rabbet 'm of said' wheel E. The molding-wheel I is revolved by means of the geared connection of its shaft B4 with the driving-shaft, through the miter-Wheels Q and Q.

The stem D of the channel-opener has a slot,y n, (seen in Fig. 2,) which extends over the pin' p, whose ends are fast; in the shell of the shaft B, to admit of th'e inward movement oftheK stem. R is a treadle-strap, whose ends are hung on the rod q, which passes through the free end of the lever J When a sole is to be placed in the machine for opening the channel and molding its edge,

the free end of the lever is borne down, whereby the wheel I is thrown backward out of the way, for connecting the channel-opener with the channel. Then the lever is allowed to come into the position shown in Fig. 2, pressing the wheel I hard upon the sole, and causing the opposite side of the latterto bind hardagainst the edge of the wheel F, the spring M yielding to the pressure until the channel-opener is forced into its position. (Seen in Fig. 2.) Then, as chev crank S is turned in either direction, the wheels E, H,1and I, and the chan nel-openerC, are revolved, and the sole car- I claim as my invention- 1'. The combination of the channel-opener C, gage-Wheel H, and molding-Wheels E and I, arranged and operating in relation to each other, substantially as and set forth.

2. The combination of the Wheel I and shaft B4 with the lever J, substantially as and for the purpose set forth.

3. The combination of the spring M with the hollow shaft B, and channel-opener C, as

and for the purpose set forth.
