SPECIFICATION forming part of Letters Patent. No. 383,254, dated May 22, 1888.
Serial No. 2:36AM. (No model.)
To all whom. it may concern:
Be it known that 1, WILLIAM SnuMoNDs, a citizen of the United States, and a resident of Yonkers, VVcstchester county, State of New York, have invented certain new and useful Improvements in Hat-Stretching Machines, of which the following is a specification.
In another application for Letters Patent, filed July 16, 1887, under Serial No. 244,447, I have described an improvement in hatstretching machines, by means of which the finishing of the crown-tip ofa felt hat is accomplished si multaneousl y with the operation ofstretching and developing the brim; and I therein claim a crown-tip flattener so constructed and operated as to be automatically laterally reciprocated on the crown-tip of a hat held in the stretching machine.
Now, this invention also relates to means for removing the marks of the tipstretching machine from and flattening the crown-tips of hats; and it consists of a fiattener arranged to bear on the crown-tip of a hat held on the former of a brimstretching machine, and r tated or caused to move in circular paths on the crown-tip, and thereby roll or rub down the marks or irregularities due to the tip stretching operation to which the hat has been previously subjected; but to describe my pres ent invention more fully I will refer to the accompanying drawings, in which-- Figure 1 is a side elevation of a hat-stretch ing machine embodying my improvements. Fig. 2 is a central section of the upper part of the machine. Fig. 3 is a section on the line Z Z, Fig. 2. Fig. 4 is an elevation ofa modification in the construction of the tip-flattener. Fig. 5 is aplan view of the same. Fig. 6 is a central section of the upper part of the machine, showing a rotating flattener of modified form and modified actuating mechanism. Fig. 7 is a plan View of the same, and Fig. 8 is an underneath view of the tlattener.
The machine here shown to which my improvements are applied is similar to that shown in my beforementioned application; so a brief description thereof will here suffice.
The main frame comprises side pieces, a a, cross-plate a and top plate, (0*. The central 5o shaft, 12, fitted to slide vertically in bearings in the frame, carries the hat holder or former c and stretching-ribs d d. This shaft b is raised up by the treadle e, and the ribs (1 (l are spread out by means of thehand-lever g. The stretching-fingers ff are hinged to the top plate, a, and are actuated from the vertically-reciprocated plate It by means of the links it. This plate It, supported by the rods 1' i, is actuated from the main shaftj through the medium of the link and lover system t M and cocoa 6o trio j.
The erowntip-flattening device shown at Figs. 1, 2, and 3 consists of the conical roller 70, carried by the arm is, secured to the shaft 1, which is held in a vertical position directly 6 5 over the axis of the former a in the light frame Z, connected to the top plate, a, of the frame. The upper part of the shaft Z passes through the sleevebcaring m, and is caused to rotate therewith by means of an ordinaryspline and groove. Said sleeve-bearing m receives motion from the main shaftj of the machine by means of the belt m, which passes over the pulley m formed on the sleeve-bearing, the pr illeym on the shaftj, and the guidepulleys m m.
The spring Z on the shaft Z, between the collar Z and the under side of the sleeve bearing m, holds the roller 7t down on the crown-ti p of the hat with a yielding pressure.
The roller 7c is arranged on a radial line on the crown-tip, with its end extending beyond the center thereof, the object of which is to insure that all parts of the erown tip shall receive a sufficient amount of rolling or rubbing action, and as the central part of the tip is generally the most deformed it receives from the roller 70 more rubbing action than the other parts, because the end of the roller which lies beyond the center of the tip will revolve in moving over the goods in an opposite direction to its direction of travel thereon, as said roller will be caused to roll on the goods in rotating by reason of the extent of its bearing on the radial line. The arrows :0 x indicate the di- 5 rection of rotation of the roller and the arrow y the direction of rolling. Asubstantiallysimilar result maybe obtained by making the flatteningroller shorter than the radial line of the crown-tip, as shown at It, Figs. 4 and 5, Ice and setting the vertical shaft Z eccentric to the axis of the former c. In this case the path of rotation represented by the dotted circle covers a part only of the crown-tip; but the roller is caused to act on all parts thereof, as the hat is turned around on the former a during the process of stretching the brim by the other parts of the machine; and it will be observed that the central part of the tip receives the most rolling action from the roller 70, because said roller during each rotation passes over this part of the hat.
A trencher or other form of tip-flattener may be made to extend entirely across the crown-tip and be rotated thereon. Such a device is shown at Figs. 6, 7, and 8, consisting of a disk, 0, having radial ribs 0 0 connected at the center. This disk is carried by a shaft, Z, held in the frame Z and provided with the spring 2 in a manner similar to the beforementioned flatteners.
In these views, Figs. 6, 7, and 8, are shown means by which the crown-tip flattcner is reciprocally rotated, the same consisting of the cord or chain p, connected at one end to the vertically-moving plate It and at the other end to the pulley r, formed on the sleeve-bearing r, and a coil-spring, s,joined at one end to the sleeve-bearing r and at the other end to the frame 1.. This spring acts to keep the chain 1) taut and to impart rotation to the shaftl and attached devices in direction opposite to that imparted by the downward movement of the plate h.
Having now described my invcntion.what I claim, and desire to secure by Letters Patent, 1s
1. The combination, substantially as set forth, with a machine for stretching hat-bodies, containing a former upon which the hat is held, of an automatically-rotated crown-tip flattener carried by the machine and arranged to bear and act upon the crown-tip of the hat, its axis of rotation being at right angles to the crown-tip.
2. In combination, a machine for stretching hat-bodies, containing a former upon which the hat is held, an automatically rotated spring-acting shaft held in the machine perpendicular to the crown-tip of the hat on the former, and a roller carried by the shaft and arranged to bear on the hat.
3. The combination, with the former of a hat-stretching machine, of a conical roller automatically rotated on a center coincident with the aXis of the former and arranged to bear on a radial line of the crown-tip of a hat held upon the former from the edge thereof to a point beyond the center, substantially as and for the purpose set forth.
4. In a machine for developing and stretch ing hat-bodies, in combination, a former upon which the hat is held, expanding ribs projecting therefrom, pivoted fingers for stretching the brim, a vertically-moving finger-plate connected to the fingers, a vertical shaft arranged perpendicularly to the top of the former, a roller carried by the shaft arranged to bear on the crown-ti p of a hat placed upon the former, and a rotating shaft of the machine connected to the roller-shaft.
Signed at Yonkers, county of \Vcstchester, State of New York, this 25th day of November, A. D. 1887.
