A. 4G. FITZ. TREEING MACHINE.
(Application led Oct. 21, 1898.,
(No Model.)
Arent AMOS G. FITZ, OF AUBURN, MAINE.
TREElNG-IVIACHINE*l SPECIFICATION forming part of Letters Patent No. 626,828, dated June 13, 1899.
Application tiled October 21,1898. Serial No. 694,189. (No modelJ la device upon which the last, either alone or with the boot or shoe thereon, may be quickly and rigidly secured, from which it may be quickly and easily removed, and which may be readily adjusted to bring all parts of the shoe into a position convenient for manipulation by the operator. It is adapted to be used with lasts having the usual spindle-hole and a special spindle-hole angularly disposed relative to the former.
In the drawings herewith accompanying and making a part of this application, Figurev l is a perspective view of my improved machine, and Fig. 2 is a central vertical section of the upper portion of the same.
Same letters refer to like parts.
In said drawings, A represents a base upon which is mounted a standard B, upon which is supported a table C. In a suitable bearing I), mounted on said table or standard, is a rotatable shaft E, having on one end a'n arm F. Extending through said shaft and arm and adapted to reciprocate therein is a spindle G, one end projecting through the free end of the arm and having its eXtreme end H bent at an angle to the main portion of the spindle. The other end has a swivel connection I with a chain or equivalent device J, traveling over a pulley or sprocket K, and thence passing down through a slot L in the table and being connected to a foot-lever M, mounted on pivot-pin X, by means of which the spindle G may be drawn back into the position shown in dotted lines in Fig. 2 when desired. The spindle is held normally extended in the position shown in the drawings by means of a spring R, which surrounds the spindle and lying between the shoulders S on the spindle and the nut T, inserted in the shaft E, in such manner that the tension of said spring tends to force the spindle outwardly. The spindle L is concentric with the shaft. The arm on the shaft is integral therewith and extends from the center outwardly toward or beyond the circumference of the shaft. Ata suitable distance from the spindle on the end of the shaft is a spur I-I, adapted to enter the ordinary spindle-hole in the heel portion of a last. The last is provided also with a-hole c, extending diagonally to the spindle-hole b, to receive the bent end of the spindle of the treeingmachine.
For convenience the bearing in which the shaft is mounted may be formed of two parts having corresponding flanges V on either side, the two parts being secured together by means of bolts V, passing through said flanges. By adjusting these bolts the friction of the shaft in its bearing may be increased or diminished to regulate the force required to turn the shaft in its bearing. The shaft may be held against endwise displacement in its bearing by flanges U, extending outwardly at either side of and close to the bearing, as seen in Fig. 2.,
interposed between the foot-lever and chain J is a section of coil-spring having sufficient tension to hold the foot-lever firmly locked when the clip N is brought into engagementl with the ratchet on the bracket O. y
Other means may be employed to impart a reciprocating motion to the spindle G and other means employed for locking the footlever without departing from the spirit of my invention.
My device is adapted to be used both with whole and divided lasts.
The operation of my improved device in the well-known process of treeing boots and shoes is as follows: The last, provided with the usual vertical spindle-hole and the auxiliary spindle-hole extending diagonally to the former, is first placed in position upon the spindle of the treeing-machine, the bent portion of the spindle entering the diagonal hole in the last while the spindle is in its normal position. (Shown in Fig. 2 in the drawings.) The foot is then placed upon the operatinglever, pressing it downwardly, whereby the spindle is drawn through the rotary shaft,
IOO
bringing the boot nearer the shaft until the spur on the end of the arm of the shaft enters the spindlehole,thus locking the last securely to the end-of the shaft, as shown in dotted lines in Fig. 2. The spindle may be locked by bringing the clip on the foot-lever into engagement with the ratchet on the bracket. Vhile thus locked the shoe may undergo the usual manipulation Without danger of being forced from the spindle. The swivel connection of the opposite end of the spindle allows the spindle to be freely rotated With the shaft. The arrangement of the spindle concentric with the shaft and the location of the usualV spindle-hole to the rear of the diagonal hole reduces to a minimum the change in the elevation of the toe and heel of the shoe caused by rotation of the shoe with the shaft during the operation of treeing, thusmaking it much more convenient for the operator.
To remove the last, release the foot-lever, when the spindle Will be automatically forced outward to its normal position by the spring, thus withdrawing the spur from the spindlehole and allowing the last to be easily removed.
The advantages of my improved treeingmachine, among others, are the facility With which the last may be placed in position or locked in position on and removed from the machine, the adjustability for purposes of manipulation while thus locked on the inachine, and the slight change of position due to the rotation of the shaft on which the last is supported.
Having thus described my invention and its use, I claiml. In a freeing-machine, a suitable supporting-framework, a rotatable shaft mounted thereon, a reciprocating spindle mounted in said shaft, one end bent at an angle tothe main portion, a spur on said shaft, and means for reciprocating said spindle.
2. In atreeing-machin'e, a suitable supporting-frame a shaft rotatably mounted on said frame and provided With an extended arm, a spindle adapted to reciprocate in said shaft and arm and having its free end. bent at an angle to the main portion thereof, a spur in the end of said arm, an ,operating-lever, a swivel on the end of said spindle, means connecting said foot-lever and swivel for operating said spindle in one direction and aspring tending to im pel it in the opposite direction.
3. In a treeing-machine, a suitable supporting-frame, a shaft rotatably mounted thereon, a spindle concentrically mounted in and adapted to reciprocate in said shaft and having one end bent at an angle to the main por-A tion, a spur eccentrically set in the end of said shaft and adapted to cooperate with said spindle to hold the last, the bent end of the spindle lying normally beyond the end of the spur,and means for reciprocating said spindle. 4. Ina treeing-machine, a suitable supportingframe, a shaft journaled thereon, a reciprocatingspindle mounted in said shaft and having its end bent at an'angle to the main portion, a spur on the end of said shaft adapted to coperate with said spindle to hold a last, means for reciprocating said spindle, means for locking said spindle when forced back and means for holding the locking-lever with a yielding tension.
In testimony whereof I affix my signature, in presence of two Witnesses, this 18th day of October, 1899.
AMOS Gr. FITZ.
