HAT-POUNCING MACHINE.

SPECIFICATION forming part of Letters Patent No. 625,699, dated May 23, 1899.

Application filed March 15, 1897.

To all whom it may concern:

Beit known that I, CHARLES I-I. REID, a

citizen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hat-Pouncing Machines, of which the following is a specification.

My invention relates to hat pouncing or sandpapering, and more particularlyto machines which perform the operation of pouncing or sandpapering hats or fabrics formed of felt automatically, and has for one of its objects the production of an automatic machine or device which will operate on every portion of the surface of the fabric alike by or through positive continuous movement of an endless belt upon which is placed or to which is secured'the pounce, powder, sand, or other material used in such operation, the speed of the belt and the movement of the hat or fabric in a directionthe reverse of the belt each being varied so that no part of the surface of the material operated upon will be cnt or worn away to a greater depth or degree than any other part of its surface operated upon.

I'Ieretofore in hat-pouncing machines provided with a hat-pouncing belt the spindle that carries the hat and the pouncing-belt have each been constructed to run at a uniform rate of speed. In this construction the tip of the hat-crown is subjected to a deeper cutting or pouncing than the body of the crown. I'V hen the rotation of the spindle is uniform, the surface of the hat in the area of the tip will be presented to the action of the pouncing-belt to an extent exceeding its acmoving in contact with the surface of the tip at a point where its circumference was eleven Serial Nol 627,679. (No model.)

for decreasing the speed of the pouncing-belt while it operates on the tip and means for increasing the speed of the spindle and the movement of the pouncing-belt supporting and swinging mechanism operated therewith, whereby the Vpouncing-belt is rapidly moved away from the surface of the tip of the crown toward its body or base, thereby preventing the tip from being cut too great a depth. I accomplish the same object when the ponncing-belt is carried in contact with the hat from the base of the crown to the tip by increasing the speed of the spindle and decreasing the speed of the pouncing-belt when the latter reaches the area of the tip. By thus providing for a diversity of motion for the spin-l die and for the pouncing-belt I am able to pounce the crown of the hat with great nicety, uniformity, and rapidity.

Another object of my invention is to provide an automatic hat-pouncing or sandpapering machine that a workman of ordinary skill and intelligence may operate readily and which will do its work with rapidity and economy. y 1

I accomplish the objects of my invention in the manner and by the means hereinafter described in detail, pointed ont, and claimed, reference being made to the drawings accompanying this specification, in which the same characters refer to like parts in all the figures of the drawings. Figure l is a side elevation showing the pouncing-belt in contact with the tip of a hatcrown supported on a block. Fig. 2 is atransverse section on line :n of Fig. l, showing the dog pivoted in the arm of the lever that holds the worm-wheel in engagement with the worm of the spindle.

showing block supporting the belt-pulley that drives the pouncing-belt. Fig. 8 is a crosssection of the pulley that carries one end of the pouncing-belt and also the belt-pulley that drives it. Fig. 9 is across-section of the pulley carrying the end of the pouncing-belt opposite the pulley that drives it. Fig. 10 is a cross-section on line z z, Fig. 6, showing the shoulder on the end of the sleeve that supports the weighted arm and the nose on the sleeve of the long arm of the angular lever which rocks or swin gs the pouncing-belt frame when the nose and shoulder interlock.

In carrying out my invention I provide a vertical standard A, having a flared circular base a to form a stable support, the upper end of the standard being provided with a horizontal platform or table B,form ed integral therewith or rigidly secured thereon. Two curved standards C C', having` their lower ends flared outwardly at right angles to form supports and receive means for attaching them to the table or platform B, rise vertically from the middle of the platform and are provided at the upper ends with collars or sleeves D D', which form bearings for a horizontal spindle E journaled therein. The outer' end of the spindle E is provided with a vertical frictional disk F, having a collar fformed concentrically therewith and extending fromv the outer face of the disk and closely fitting the spindle and being rigidly secured thereon by set-screws passing through threaded apertures in the collar and their ends resting in contact with the surface of the spindle. The opposite or inner' end of the spindle E has a block G, removably secured thereto by a chuck H, the jaws 7L 7L being opened and closed by the movement of a collar I, which surrounds the spindle near its inner end. This collar is moved back and forth on the spindle E and in and out of contact with the jaws 7b h of the chuck by a lever K, provided with a handle 7V' and pivotally connected to the collar at its lower end. The lever K is fulcrumed near its lower end between the arms l Z of a bracket L b v means of a pin Z passing through an aperture in the arms and in the lever, the shank or stem of the bracket L being secured by any suitable means to the top of the journal bearing or collar D@ The circumference of the spindle E between its journal-bearings D D is provided with a worm e, which meshes or interlocks with the teeth or spurs m, formed on the circumference of a worm-wheel M, vertically mounted within the curved standards G C on a short ,shaft N, rigidlysecured in an aperture in the lever rises vertically from the heel, where fulcrumed, to the height of the upper circumference of the spindle and has pivotally secured to its upper end one end of a connecting-rod or draw-bar P, pivotally attached at its other end to a lever Q, near the lower end thereof, the lower end of the lever being pivotally attached to the arms of the bracket L and its upper end having a handle q for operating it. The face of the standard C is provided with a projecting pin q', that snpports the outer end of the arm O when the lever is dropped.

The free end of the horizontal arm O of the lever has a lengthwise slot R through the side thereof and has pivoted vtherein a springpressed dog or pawl R, provided with a tail r, which projects parallel with and toward the inner end of the lever., A spiral spring S is secured between the tail r and the lever O. A pintle s passes through apertures in the lever above and below the slot and through the dog or pawl and holds the dog or pawl pi votally therein. The inner edge of the dog is provided with a nose T, which is thrown by the action of the spiral spring S into a recess t, formed in the facev of the standard C at a point opposite the center of the wormwheel when the latter is lifted by the lever into contact with the worm on the spindle. The face of the worm-wheel has attached thereon a beveled trip or wiper U, which engages with the dog R' when the wheel rotates and throws the nose of the dog out of the recess t and permits the lever-arm O to drop against the pin q', the rotation of the wheel ceasing the instant the lever draws it out of engagement with the wormed spindle.

A crank V, provided with a weight or counterbalance o at one of its ends, is rigidly secured midwayof its ends to the outer end of the shaft N and has pivotallyconnected with its light end W the end of alink w, the other end of which is pivotally attached to the short arm of a bell-crank or angular levery, pivotally secured at its elbow to the end of a shaft Z, journaled in a sleeve-bearing z, formed on the end of the arm of a horizontal bracket Z, secured to and supported at the side of the journal-bearing D on the upper end of the standard C. The bracket Zl projects outward from its point of attachment for a distance and -then extends parallel with the spindle E and terminates beyond the inner end of the block secured theretoand supports the mechanism operating the pouncing or sanding belt.

I Two loose grooved pulleys l 2 are journaled on va short shaft passing through the side of the arm of the horizontal bracket Z at a point thereon opposite the chuck Il on the spindle E. These pulleys l 2 receive a belt 3 4, which passes around pulley 3, rigidly secured to a frictional disk Z2, normally in frictional contact with the face of a disk Z3, mounted on a shaft journaled at each of its ends in a supporting-frame Z4, which frame may be se- ICO IIO

cured at any suitable or convenient point above the hat-pouncing machine or adjacent thereto. Secured to the side of the disk Z2, concentric therewith, is a pulley 4,which may receive a belt from a line-shaft or countershaft for imparting motion thereto. The disk Z2 is mounted on a shaft journaled at each of its ends in a supporting-frame pivotally attached to the frame supporting the disk Z2. The face of each of these disks opposite the pulley therewith is slightly rounded, and these rounded faces are held in contact with each other by a spring which presses the frame of the adjustable or movable disk Z2 toward the fixed disk Z3, the outer circumference of the face of disk Z2 resting normally in contact with the face of disk Z3 at a point nearthe shaft on which it is mounted. When the disks are in their normal position and disk Z3 is rotated, disk Z2 moves at a lower rate of speed than disk Z3; but when the frame carrying disk Z2 is swung so as tol change the position of the faces and bring the outer circumference of the face of disk Z3 in contact with the face of disk Z2 near its shaft, disk Z2 is rotated at its highest speed. Zhen the faces of the disks are in contact near their outer circumferences, their speed is equal. If the circumference of disk Z3 where it contacts with Z2 is twice the circumference of the face of the latter disk where it contacts, then one complete rotation of disk Z3 will cause two complete rotations of disk Z2. Any suitable means may be used for swin ging the pivotally-supported frame, such as a strap or cord attached thereto and within reach of the operator to vary the speed of the disk Z2. A full description of this speedvarying device is disclosed in Letters Patent of the United States No. 128,773, issued July 9, 1872. I do not, however, limit myself to the device here named for varying the speed of the pouncing-belt. I may use any suitable speedvaryin g device for that purpose in accomplishing` the objects of my invention. The belt is received by the pulley 1, runs thence to and around a grooved pulley 5, supported by the shaft Z, j ournaled in the sleevebearing c, and returns under and around the pulley 2, aXled with pulley 1, or vice versa, it making no difference which of the two pulleys first receives the belt 3 4. A grooved pulley 6 is formed in the face of the wheel that receives the power from the belt 3 4. The downwardly-projecting arm of the bellcrank 'lever y is provided with a sleeve 7, formed integral with its lower end and projecting inwardly. This sleeve 7 receives a shaft 8 therein on which are journaled two connected loose pulleys 9 10, rigidly formed on each end of a collar 11, the pulley 9 being of less diameter than 10. Pivotally secured at its lower end, on the outer end of the shaft 8, is an arm or standard 12, the upper end of which is provided with a collar 13,

through which passes and to which is rigidly' secured by a set-screw the longitudinal arm or shaft 14 of the frame, in which the pulleys are journaled that carry the pouncing or sandpaper belt 15. The arm 12 is held in a movable upright position by a depending weighted arm 16, that is attached by its upper end to a sleeve 17, secured on the inner end of the shaft 8, the sleeve being held in rigid contact with the shaft by a set-screw 18. The length of the weighted arm 1G may be adjusted on the sleeve by a set-screw. The

inner end of the sleeve 17 has formed thereon l the arm 12, supporting the pouncing-belt,when

the bell-crank is pulled back and forth by the link w, attached to the short arm .fr thereofand operated by the worin-wheel mechanism. The weighted arm draws the frame of' the pouncing-belt toward the block G. The frame, supported by the rocking arm or standard 12, consists of a cylindrical shaft 14, having brackets 22 23 attached to each of its ends in any suitable manner, and to which are journaled pulleys 24 25, carrying the pounciug-belt 15.

The pulley 24, secured to the bracket 22 at the outer end of the frame, is provided with a groove 26, which receives the belt-pulley that gives motion to the pouncing-belt. The construction of this pulley 24, and the sleeve on which it is journaled and secured to the bracket, is shown in cross-section in Fig. 8.

IOO i The construction of the pulley 25, journaled `A block 27, having two loose grooved pulleys 28 29, journaled opposite each other at its sides, is provided with an eye 30, through which the shaft 14 passes. The block is secured to the shaft by a set-screw 31. .These pulleys 28 and 29 receive and return a beltpulley 32, carried around the grooved pulley 10, mounted on the shaft 8, their use being to change the direction of the belt 32 from transversely of the belt-supporting france to a'direction parallel with the pouncing-belt. The belt 32 passes from the pulleys 28 29, mounted on the block 27, to and around pulley 24 and in the groove 26 therein and imparts motion to the pouncing-belt. The pulley 10, carrying the belt 32, is driven by a belt 33, carried from the grooved pulley 6, journaled to the shaft Z, supported in the sleeve on the end of the arm of the bracket Z. The grooved pulley 6 is rigidly connected with grooved pulley 5, which is driven by the belt 3 4, previously herein described.

Acollar 35, provided with a set-screw 36, is mounted on the shaft 14 and has formed eccentrically thereon an arm 37, the free end of which is beveled or rounded. This arm has secured to the outer side thereof a presserfoot or gage 38, curved at its lower end and carried around the end of the curved arm.

IIO

The straight part of the presser-foot or gage has a longitudinal slot therein to receive a set-screw 39, by which its length may be adjusted and its pressure against the article carried by the block G while undergoing the pouncing operation be limited, its use being for the purpose of holding the frame carrying the pouncing-belt at a proper distance from the block and of regulating the pressure of the pouncing-belt against the hat and preventing the belt from cutting too deep at any point during its movement vbetween the tip and the base of the hat-crown. The presser-foot or gage 38 travels immediately back of the rear edge of the pouncing-belt. The movement ofthe pouncing-belt as it runs in contact with the hat maybe from the tip upward and to the base of the crown on the upper circumference of the block or from the base of the crown down to the tip; but in the latter movement the gage will be in front of the pouncing-belt.

Motion is imparted to the operating mechanism which revolves the spindle by a bandpul1ey40, driven by a line-shaft or countershaft pulley. (Not shown in the drawings.) The band-pulley 40 is carried by a drivingpulley 4l, mounted on the outer end of a shaft 42, journaled in a bearing 43, formed on the upperend of a vertical standard rising to the height of the standard C, its base being secured to the floor, only the journalbearing 43 at the top of the standard being shown in the drawings. The opposite end of the shaft 42 is journaled in the side of the collar D. The shafty 42 is shown in broken sections in Fig. 3. This shaft 42 is provided with a frictional gear-wheel 44, the circumference of which contacts with the face of the frictional disk F on the end of the spindle E. The frictional gear-wheel 44 is provided with a collar 45, whichextends for a distance on each side thereof, but having a greater length projecting toward the drivingpulley. This collar has formed lengthwise of its interior circumference a spline or groove that receives a feather 4G, attached to the circumference of the shaft 42 longitudinally thereof. A cylinder 47, having a cam-groove 48 formed in its exterior circumference that winds to its outer end and returns to its inner end, making one complete revolution thereon, is rigidly attached to the shaft carrying the worm-wheel M at the end opposite its bearing-support. An arm 49, having an antifriction-Wheel 50 journaled at one of its ends and provided with two fingers 5l at its opposite end, that rest one on each side of the frictional gear-wheel 44 and loosely clasp the collar thereof, travels back and forth the length of the cylinder 47, with the antifriction-wheel 50 resting in the groove therein, the frictional gear-wheel 44 at the same time sliding back and forth on the revolving shaft 42 and with its periphery in frictional contact with the face of the disk F, thereby imparting a revolving motion to the spindle E,

to the worm-wheel M, and the gro'oved cylinder secured to the shaft of the worm-wheel. The speed at which the'spindle revolves varies uniformly from fast to slow as the frictional gear-wheel 44 moves from near the spindle, at which point the speedl is fastest, to the outer circumference of the disk, where it is slowest.

The pouncing or sandpapering belt l5 may be made of any suitable iexible fabric or material and the pounce or sand secured to the surface thereof by any of the various means used to cause such material to permanently adhere thereto.

A belt of felt or other material destitute of pounce or sand for burnishing the hat or article may be substituted for the pouncing or sand paperin g belt when desired, the construc- 'tion of the frame and the pulleys carrying the belt permitting of the ready removal of the belt therefrom and replacing it with another.

The weighted arm 16 when properly adjusted on the sleeve that supports it and when the sleeve is also properly adjusted on its supportingshaft swings the pouncingbelt frame toward the end of the spindle E, its movement in that direction-being limited by the contact with each other of the nose or shoulder formed on the sleeve that supports the weighted arm and the nose or shoulder on the sleeve formed on the end of the bellcrank lever y. This adjustment of parts may be so nicely made that the pouncing-belt will press on the article carried by the block G with any degree of force required, its pressure being limited only by the presser-foot or gage 38, which travels in the rear. The pouncing-belt frame may be swung away from the block by the hand of the operator, but little force being necessary when a nice adj ustment has been made.

It will now be understood from the description of my hat-pouncing machine that the means for rotating the spindle that carries the block on which the hat or other article to be pounced or sandpapered and the means for running the pouncing or sandpapering belt in contact therewith produce dissimilar rates of speed. The spindle may be set in motion at the point Where it will rotate at its lowest rate of speed and the pouncing-belt,

IOC

IOS

moving at its highest rate of speed, swung regulated that the cutting away of the surface of a hat at any point from the tip to the base of the crown, or vice versa, to too great a depth is prevented;

lnpouncing or sandpapering a hat from the tip to the base of the crown the spindle may be rotated at a high rate of speed at the tip and the pouncing-belt at its lowest rate of speed, the relative speed of the spindle and of the belt being maintained when the crown of the hat is oval. When the pouncing-belt reaches the body of the crown, the speed of the pouncing-belt is increased to operate on the increased area, while the speed of the spindle is decreased to give time to the pouncing-belt to perform its work. Any or every part of the surface of the hat operated upon by the pouncing-belt may be gone over a second time or as often as desired. When the base of the crown is reached, the movement of the pouncing-belt may be back to the tip.

The trip or wiper U may be movably secured to the face of the worm-wheel at any operative point thereon to engage with the dog R and drop the wheel out of contact with the spindle and at the same time rock the frame carrying the pouncing-belt away from the block.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is*
