HAT-SIZING MACHINE.

SPECIFICATION forming part of Letters Patent No. 463,339, dated November 17, 1891.

Application filed J' anuary 17, 1891. Serial No. 37 8,096. (No model.)

To all whom, it may concern:

Be it known that we, WILLIAM SIMMoNDs,

'of Yonkers, in the countyof Vestchester and State of New York, and CHARLES LINEGAR, of Yonkers, in the county of l/Vestchester and State of New York, both citizens of the United States,` jointly have invented certain new and useful Improvements in Hat-Sinin g Machines, of which the following is a specification.

- Our invention relates to that class of machines in which a number of hats in a soft condition and before the formation of their brims are wrapped in a cloth and passed be` 'work progresses and to regulate their pressure on the work by springs or weights adjustable by hand.

One of the principal objects of our invention is to start with an adjustable normal pressure, the rolls being at a definite distance apart, and gradually automatically to dimin-l ish such distance as the operation progresses. Our improvements consist 1n certain novel constructions, organizations, and comblnations of instrumentalities hereinafter claimed,

which not only enable us to attain this object, but to produce a cheap, simple, and effective machine.

The accompanying drawings show so much of a three-roll hat-sizing machine embodying all our improvements as is necessary to illustrate their subj ect-matter. Some of these improvements may, however, berused without the others and in machines differing within certain limits in their details of construction from those herein shown. Unless otherwise indicated, the parts are of usual construction.

Figure l represents a vertical central longitudinal section through the machine on the line 2 2 of Fig. 2, which is a front elevation.A

That end of the -machine at which the operator stands we term the feed or frontend, and the opposite the rear7 end. That side on the right of the operator facing the machine we call the right side, and the opposite the left forwardvend. `"A pressure-roll D is mounted' in bearings in a frame D', swinging in a verticalplane around a rock-shaft or pivot d on the rear of the main frame. The pressureroll D is shown as lying above and between the sizing-rolls C C'. This pressure-roll D, being mounted in the yielding frame D', is free to rise and fall relatively to the fixed rolls. The normal pressure of this yielding rollD is regulated by an adjustable tension device, such as a spring or weight. The drawings show this device as consisting of an arm cl2,

projecting from the rear of the frame, onf

which arm an adjustable weight Dgslides, the pressure it exerts thus depending on its distance from its pivot d. The rolls may be provided with ns, lags,.or ribs of variousforms properly to work the hats. XVe prefer short, straight, central ribs c, parallel with the axis, as shown, the ends of each of these ribs being overlapped by ribs c', also parallel to the, axes of the rolls. Links c e' are shown on each side of the machine as pivoted to the swinging pressure-roll frame D at their upper ends, their opposite ones being linked to corresponding side bars E E', rocking on piv-I ots c2 on the frame and connected bya crossbar E2, thus constituting a pressure-frame which may be controlled by the foot of the operator. A rod F is pivoted to the table and has a forwardly-projecting arm f, which au tomatically engages with the cross-piece E2 when the pressure-frame is fully depressed. This rod constitutes a stop to hold the roll D in its elevated position and also to hold the automatic stop mechanism or roll-lowering devices out of operation, as will be hereinafter described.

An intermediate cross-rod G on the pressure-frame carries a swinging arm G', having a polygonal socket g, in which the correspondingly-shaped lower end -of a screw-spindle g' its. The rounded screw part of this rod works in a corrosponding socket in a hub H, turning in bearings in a bracket H', screwed to the under side of the table and carrying aratchet-wheel 7L on its upper end, which ratchet-wheel is actuated by a pawl c' on a IOO rocking lever l, actuated by a pitman t" and crank-wheel I on a shaft J. A latch-lever K, rocking on a pivot 7.: and connected by a link 7o with the pressure-frame, serves to free the pawl from the ratchet-wheel at the proper time. When thus free, the screw spindle g' can be raised or lowered by turning it in its bearings by means of gears m m', actuated by a hand-crank M. A spring k2 normally holds the latch-lever out of contact with the pawl, and a loop k3 on the link 7c allows the pressure-frame to rise without affecting the latch, which only operates when the pressureframe is depressed to its full extent. The organization, it will be observed, is such that when the cross-piece E2 is not held down by the foot of the operator or by the stop F the weight of the presser-roll frame is sufticien t to overcome that of the side bars E E and to cause the presser-roll to fall, and that when the spindle gis screwed up it merely removes the pressure that holds these side bars down and permits them to rise when actuated by the weight of the supplementary or presser frame.

The various parts may be driven in wellknown ways. A belt or chain j from a pulley N is shown as driving a corresponding pulley J on the crank-shaft J. The roll C is also driven from the pulley N by a belt n in a similar way, and another belt n from this roll drives its companion roll C. The pulley C ,by means of a chain n', drives an idler N', and a chain from this pulley drives the yielding or pressure roll D. The rolls are caused to revolve in the direction indicated by the arrows.

The operation of our improved apparatus will readilybe understood from the foregoing description.

The hats in usual condition are fed in between the fixed rolls C C and the pressureroll D, the adjacent surfaces of which rolls all turn in the same direction from front to rear, as shown by the arrows, Fig. l, and the hats are felted or lfulled, as usual. The ratchetwheel turns the hub step by step correspondin gly with the revolution of the rolls, and thus screws the spindle g up into the hub. This permits the front part of the pressure-frame E to rise and allows the pressure-roll D to descend accordingly. lVhen the spindle ghas risen to its full extent, the pawl is lifted by depressing the front part of the pressureframe and the stop F allowed to engage with the cross-bar E. The ratchet-wheel and hub are their turned backward by the gears m m and hand-crank M. The depression of the pressure-frame -also lifts the pressure-roll D for the insertion ot a new batch ot" hats to be treated. lVhen ready to start the machine again, the stop F is disengaged by the foot of the operator. lVhen the attendant leaves the machine, he depresses the pressure-frame, allows t-he stop F to engage with the bar E2, and the descent of the roll D is delayed until he returns. By forcing the'stop Fout of enl gagement with the pressure-frame the gradual descent of the roll D again takes place.

Our improved organization enables the pressure-roll to operate with an adjustable definite pressure and gradually to approximate the, (ixed rolls as the operation progresses, the stop restraining this approximation being gradually retracted automatically, as above explained. Meanwhile the pressureroll is free to yield to inequalities in the hats operated upon, which it obviously could not do were the stop mechanism rigidly connected with it.

Having thus fully described the construction, organization, and operation of our improved hat-sizing machine, what we claim therein as new and as of our own invention l. rlhe combination, substantially as hereinbefore set forth, of 4sizing-rolls, a presserroll movable laterally relatively to said sizing-rolls, stop mechanism connected with the presser-roll, and means for actuating this mechanism to permit the presser-roll to move connected with the pressure-roll for permit ting it to move toward the sizing-roll, but which allows the pressure-roll to move freely away from the sizing-rolls, and means for actuating the stop mechanism to permit the presser-roll to move gradually toward the sizin g-rolls.
