MACHINE FOR PARING CURLED EDGES OF HAT-BRINIS.

SPECEFICATION forming part of Letters Patent N0. 587,943, dated'August 10, 1897.

Application filed December 2l, 1896. Serial No. 616,484. (No model.)

To all whom it may concern.-

Be it known that I, CARL EICKEMEYER, a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Machines for Parin g the Edges of Hat-Brims, of which the following is a specification.

This invention relates to improvements in the machines for paring the edges of hatbrims for which Letters Patent were'granted to Rudolf Eickemeyer, llo. 317,324, dated May 5, 1885, and No. 386,457, dated July 24, 1888. The machines described in these patents, while answering to some extent the purposes for which they were designed, did not meet, Without complicated changes, the requirements in paring the edges of hat-brims of various styles of curl. Hats whose curls are the same at the front and sides, as so-called flat curls, could be clamped and pared by the machine shown in the later patent, but where the curl is heavy or thick on the sides not only the clamps were, but also the rotary cutter was, of little use. Unless the brim was wedged up in the front and rear of the hatbrim, so as to make the path of the edge of the curl lie in a horizontal plane, the cutter would not work properly. My im proved machine is designed to obviate this difficulty, as it permits the paring of the edge of the hatbrim without requiring the edge to be leveled by Wedges by the use of a clamp by which the hat can be centered without the aid of the central chuck heretofore used. The inside faces of the clamps are knurled, so as to hold the outside edge of the curl rigidly in position, while the rotary cutter follows the edge of the brim and is adjustable to curls of any size from a iiat curl to the largest curl required. The mechanism for lifting the rotary cutter is operated automatically with the rotation of the hat bed-plate, on which the hat is pressed while being clamped. The slight pressure enables the hat to be clamped with its curl perfectly symmetrical on all sides. The path of the rotary paring-knives can be changed in one adjustment by the use of a main cam and suitable levers to full quarters, regular oval, or cut-out quarters on the hat-brim edge. By throwing the cutter out of cutting position when placing a hat on the bed-plate and clamping it thereto an eccentric operated by a crank is employed, said crank carrying in its interior a locking-pin which locks the cutters either in their outward orin their cutting position.

In the accompanying drawings, Figure l represents a vertical central section of my improved machine for paring the edges of hatbrims, in which one-half of the hat` is shown in clamped position, with the rotary cuttingknives in position for operation, while the knurled faces of the clamps are shown on the other side of the elevation. Fig. 2 is a plan view of Fig. l. Fig. 3 is a side elevation of the cutter-supportin g spindle and cross-head, partly in section and with bed-plate, oval cam-plates, and cutting knives removed. Fig. 4 is an end elevation of my improved machine, taken from the opposite side to that shown in Fig. 3; Fig. 4, a sectional detail of parts of Fig. 4. Fig. 5 is a plan view, with parts broken away, showing the cams, camholders, and forked cam-roller carriers and other accessories.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, a represents a hat after the brim edge of the same has been cur1edover a matrix in the curling-machine and the top of the edge ironed and set on a top-ironing and brim-edge-setting machine. After the matrix has been removed from the curl the hat a is placed on a clamping-plate a', which is fastened to a circular plate a2 by means of screws a3. The circular plate a2 is slotted to carry a cross-head a4, which in turn is supported on a vertical shaft a5. Between the clamping-plate a and circular plate a2 is interposed a circular cam-plate a, which is operated by a handle-lever a7 and clamped by a thumb-nut as in connection with a bolt co9 and arc-shaped guide-slot@10 in clampingplate a. The circular cam-plate a operates the clamping-fingers au, which are so improved that in connection with the paringknives the hat is properly centered Without the use of a central chuck or curl-supporting wedges. The clamping-iingers au increase gradually in height from -the plate a as the curl of the brim becomes larger or thicker to ward the sides of the curl and decrease gradually from the sides toward the opposite end IOC of the curl. The clam ping-li ngers-are knurled on their inner faces and clalnp the briin on the outer side. They are adjustable to any oval by set-screws @12, which are carried by supports @13, that are in turn attached to crossheads C011, guided in radial slots @L15 of the circular cani-plate d6.

'The vertical spindle a5 carries at itslower end a cam Z9, below which and forming a part of the saine are horizontal rails which forni guides for a cam-roller fork ZJ, that carries at its outer end a roller Z92, which turns on a bolt Z93, that is carried by a hub at the outer end of the fork Z9. On the hub of the fork presses a rod Z94, which is carried by a double bracket Z95, said bracket being rigidly fastened to a shaft Z96 by means of clamping-screws Z97. The shaft Z96 forms the fulcrurn for the double bracket Z95, which carries at one end a screw Z98, by which the cam-roller b2 can be released from the cam Z9, if desired. The shaft Z96 is su pported inbearings of the brackets c c, which extend laterally from the main frame c. The longitudinally-shifting rnotion of the shaft Z91 in its bearings c c is prevented by a collar 199, applied by a set-screw to one end of the shaft, adjacent to one of the brackets c, and by the hub of a lever Z910, that is attached by setscrews to the opposite end of the shaft Z96, adjacent to the other bracket c', as shown in Fig. 5. The outer end of the lever Z910 carries a pivot-pin Z111, which forms the bearing forthe lower end of a knuckle-joint Z912, to the upper end of which is pivoted a link 511, that is slotted at its upper end Z915. To the slotted upper end Z915 of the link Z911is'clarnped a pin 1916 by means of a thumb-nut Z917 and washers Z918, that are interposed between the slotted end Z915 and the thu1nb-nut Z91.7 and between said slotted end and a shoulder on the threaded pin Z916, as shown in detail in Fig. 4. The pin Z911 furnishes a bearing for a clamp Z919, the angevof which laps over the slotted end of a lever Z920 and is pressed against the same by a sleeve Z921, which is knurled at the out'- side, that it can be readily taken hold of in screwing the interiorly-threaded sleeve on the threaded shank of the clamp Z919, whichcarries the head of the pin Zils. The lever Z920 turns on a pin Z922, which is supported by brackets c4, projecting from an upright frame c1, as shown in Fig. l. The forward end of the lever Z920 is provided with a double fork Z928. (Shown in Figs. l and 2.)

The vertical spindle a5, located below the clamp-plates, carries above the cam Z9 a second cani d, below which, similar to cam Z9, are horizontal surfaces which form guides for a second cam-roller fork d', that carries at its outer end a roller-d2, that turns on a bolt d3, carried by a hub on the end of the fork d. Against the end of the hub of the fork presses a rod (Z4, which is supported by a double bracket d5, said bracket being rigidly attached to a shaft d6 by means of bolts CF. The shaft d6 forms the fulcruin or rock-shaft for the bracket d, which carries a set-screw d8, to

which a wire or cord c is attached that passes around a grooved pulley c on the rod Z91 and over a grooved pulley e2, carried by the frame c2. To the end of the cord e below the pulley e2 is attached a weight w, as shown in Fig. 4. The weight w exerts pressure on both double brackets b5 and d5, so that the camrollers b2 and d2 are constantly kept in contact with the faces of the cams Z9 and d, except when the screw Zas is used incases in which the brim edges of flat or nearly fiat curls have to be pared. v

The rock-shaft d turns in bearings of a bracket c1-and a boss c3 on the main frame c2. The shaft d6 is prevented from shifting in longitudinal direction by a collar dg, applied by a set-screw to one end of the shaft, and by the hub of a slotted lever d10, applied by setscrews to the opposite end of the shaft, as shown in Fig. 5. To the slotted lever d10 is clamped a pin e211, which is provided with a collar that is shiftable in the slot of said lever and that can be clamped in anydesired position in the same by a thumb-screw d12 and washer d13. The opposite end of the pin e111 forms the bearing for the end of a link d, which is shown in Figs. 3 and 4 in its iniddle or vertical position, in which position the slotted lever d10, although constantly in vibratory motion, does not affect the movement of the rotary cutter, so that consequently the brim edge is pared to a regular oval. Should the quarters requirecu tting or be left full, the lower end of the lever c 14 isV swung to one side or the other in the slot of the lever d10 and clamped at the desired point, according to the amount to be taken oft' or according to the amount to be left on the quarters of the hatbriin edge.

At the upper end of link d is a knucklejoint d15, the lower pin d'1 of which serves as a pivot for the link d14. The upper pin d of the knuckle-joint C115 forms, the pivot for the arm of a cranked lever d, which is fulcrunied to a transverse pin d1, supported by brackets c5, said brackets forming a part of the vertically-movable frarne c7. The cranked lever CZ1S has a downwardly-extending arm which is connected by a pivot-pin d20 with a. link C121, which is strapped to an eccentric e122 on a shaft CPS, that is supported in bearings of rearwardly-extending brackets a8 of a lever-frame C10, which is provided with bearings c11 and C12 for an inclined spindle 013, to the lower end of which the cutter-head c1l is applied. To the opposite end of the shaft 0123 is applied a crank-handle 24, which carries a spring-pressed locking-pin C125, to the end IOO IIO

of which is applied a kn urled wheel CPG. The

ylocking-pin (F5 is pressed into either one of to be turned through an angle of one hundred and eighty degrees until the locking-pin LZ25 engages in the rear hole d20.

Tothe inclined spindle G10 is splined a pulley cd15 in the usual manner, which enables the spindle to have a slight longitudinal movement independently of the rotary motion transmitted to it by a cam-belt from a counter-shaft ci? and fast and loose pulleys 010 and C17. The inclined spindle C13 carries the collars C18 and 010 at its upper end, between which is located agcross-head c20,'which in turn carries the guides 021, that prevent both the rotary movement and the longitudinally-shifting motion of the same independently of the guides or the double fork of the lever Z120.

The lever C10 is fulcrurned by suitable bearings to the conical ends of screws 022, about which it can be turned independently of the cross-head 020 and the double fork Z323 of the lever` Z920, the guides 021 of which are so constructed as to allow of a sliding movement radially with respect to the axis of the screws 002. The frame c7 is vertically adjustable for the purpose of permitting the changing of the initial position of the cutter-head. The adjustment of frame cT is accomplished by a screw 023, having a hand-wheel C04 in the upper part of the upright frame c7. The frame c7 is firmly clamped after adjustment by means of bolts 020, which engage slots of the bracket-frame C27, that carries the countershaft 015.

The adjustment of the oval mechanism so that the rotary cutter with relation to the hatbrim edge describes the desired ovalis accomplished by changing the relation of the axis of the vertical shaft a5, which has its vertical bearing in a hub carried by a plate K2, to that of the center of the circular guide K on plate K. Said circular guide K forms a bearing for a curved cross-head K3, the concentric surfaces of which engage in corresponding slots of the circular plate a2. The plate a2 is also slotted to form guides for the crosshead, to which motion is given by the curved cross-head, which is tangential. The said resultant motion, which is transmitted to the circular plate a2 by means of the two crossheads K0, produces the desired ovals, the eccentricities of which 'are proportional to the distance between the axis of the vertical shaft d5 and the axis of the circular guide K, which, when these two axes coincide, reduces the oval to a circle. The bed-plate a' being carried rigidly with the circular plate a2, the desired oval motion is therefore transmitted to the same. The proper adjustments are effected by means of a knurled hand-wheel K4 on a screw K5, having bearing in lug K0, which is carried by the plate K2. The screw K5 engages with the th reads in lug K0, carried by plate K, and the axial motion of said screw is prevented by collar KTand the wheelhub. The position of the described oval is adjustable by means of a hand-wheel Z,

mounted on shaft Z', which has a bearing in the lug Z2, carried by plate K2. ment of shaft Z', which carries screw-threads on its end, is prevented by a collar on the one side and the wheel-hub on the other. screw-threaded portion of shaft Z engages with the threads in the lug Z0, carried on the end of a boh'J which is rigidly fastened to the main frame of the machine.

The machine being adjusted for the required oval the lever Z215 is clamped in the required position with regard to the lever Z920 so as to lift the rotary cutter to correspond to the thickness of the c url to be pared. The desired style of quarters is produced by swinging the lever CZM to its required position and clamping it at the same time by means of thumb-screw d1?. The proper adjustment being made and the rotary cutter being in its released position the hat to be pared is clamped by turning the lever a7 and is held in the clamped position by thumb-wheel a8.

The rotary cutter is then swung into its aeting position by removing the locking-pin cZ25 from the hole CZQS (shown in Fig. l) and replacing the locking-pin in av corresponding hole arranged at an angle of one hundred `and eighty degrees from the same, thereby placing the cutter in the position shown in Fig. 1. By moving the plate K2 by means of the handwheel Z the hat-brim edge is moved to the cutting position. Further operation of the machine is merely the quick movement of the bed-plate a by hand through one revolution, during which revolution the hat-brim edge has been automatically and at the same time symmetrically pared, as desired. The cutter is then shifted to its released position, and by a simple reverse operation to that of clamping the hat is unclamped and the machine is ready to receive the next hat of the same style without any further adjustment.

Having thus described my invention, I claim as new and desire to secure by Letters Patent` l.
