HAT-POUNCING MACHINE.

SPECIFICATION forming part of Letters Patent No. 556,400, dated March 17, 1896.

Application filed August 8, 1894. Renewed July 20, 1895. Serial No. 556,628. (No model.)

To aZZ whom it may concern.-

Be it known that I, GEORGE R. CLARKE, a citizen of the United States, residing at Montell, in the county of Uvalde and State of Texas, have invented certain new and useful Improvements in Hat-Pounoin g Machines, of which the following is a specification.

My invention relates to the class of machines employed in pouncing felt hats, and the object of the invention is to provide a machine which will automatically pounce the hat-body whatever maybe its contour, means being provided for setting the pouncer or pouncing-roll to bear uniformly on all parts ofthe convex surface to be pounced. v

The invention will be hereinafter fully described with reference to the accompanying drawings and its novel features carefully defined in the claims.

In the drawings, Figure 1 is a front view of a machine embodying my invention, and Fig. 1 is a detached view showing the belt shifting lever in a position different from that seen in Fig. 1. Fig. 2 is a side view of the machine, the right-hand side being represented. Fig. 3 is a plan of the machine. Fig. 3 is a horizontal section at line :0 in Fig. 4.. Fig. 4 is a vertical section of the machine,

'taken in the plane indicated by line 00 x in Fig. 2, and Fig. 4 is a plan view of the wheel 28 detached. Figs. 5, 5, and 5" are detail views on a larger scale than the principal views, illustrating the construction of the pouncer or pouncing-roll.

1 designates the frame of the machine, here represented as a hollow pillar of cast-iron.

2 is the driving-shaft, rotatively mounted in bearings on the base of the pillar and bearing a tight pulley 3 and loose pulley 3 Mounted rotatively on the top of the pillar (at 4 in Fig. 4) is the carrier 5 for the hatblock and hat to be pounced. This carrier is capable of oscillating to and fro about a vertical axis through a quarter-rotation,or ninety degrees, and has a pendent tubular shaft 5 The axis of the tubular head of the carrier 5 is at right angles to the axis of the shaft 5 and as here shown the former is horizontal and the latter vertical. Rotatively mounted in the carrier is the shaft 6, which carries the hat-block 7 and the hat thereon. This shaft 6 is tubular and carries a clutch 8 to hold the block and a hand-wheel and screw 9 for operating the clutch. In Fig. 4 the clutch is shown and the hat-block omitted. I need notdescribe this clutch further than to say that it has three jaws with arms looselyhinged at their inner ends to a collar on a shaft or spindle 9 fixed in and forming a continuation of the screw 9, and that when the screw 9 is drawn back the jaws of the clutch are caused to clamp on a pin in the hat-block, the clamping being produced by inclines on the arms of the jaws, which play through apertures in a clutch-plate 8 The shaft 6, called the block-shaft, is rotated through the medium of a bevel gearwheel 10 on said shaft, which gears with a bevel-pinion 11, fixed on the upper end of a shaft 12, rotatively mounted in the axis of the carrier-shaft 5 and extending down to the bottom of the pillar or frame, where it has a step-bearing. The shaft 12 is driven from a counter-shaft 13 in the base of the pillar through the medium of miter-gears 14, and the counter-shaft is driven from the main shaft 2 through the medium of gearwheels 15 and 16 on the respective shafts.

Preliminary to the further description of the construction I will say thatwhile the block-shaft (i, with the block and hat, is rotating the carrier. 5 turns slowly about its vertical axis through a quarter of a rotation, carrying the hat under a rotating pouncing roll or head, which thus traverses the surface of the hat-body from the center of the crown to the band. This pouncing-roll is carried in a hinged frame and the roll is moved in and out to conform to the position and contour of the hat-body through the medium of a cam-plate 011 the carrier 5 and intermediate mechanism to be'described.

17 is the frame which carries the pouncingroll 18. The frame 17 has hinge-bearings below at 17 Fig. 1, on the main shaft 2. At its upper end is mounted a counter-shaft 19, which is driven from a pulley 20 on the main shaft through the medium of a belt 21 and a pulley 22 on the counter-shaft 19. The

pouncing-roll 18 is secured to an obliquelyarranged shaft 18 mounted in bearings on the frame 17 above the counter-shaft 19, Fig. 1, and carries a beveled friction-pinion 18 driven by a friction-wheel 23 on the counter-shaft 1.). A weight 17 on an arm on the frame 17 supplies the yielding pressure which tends to keep the pouncing-roll pressed up to the hat on the block.

Pivoted in the frame 17 by means of pivotbearings at 24% is a guiding-lever 24, the upper end of which bears on the surface of the hat on the block, and the lower end of which is provided with a set-screw 24, which bears on a cone 25. This cone is fixed on a cross shaft or bar 25 mounted in the frame and adapted to slide endwise to a limited extent. This shaft is moved in one. direction by means of a spiral spring 25 and in the other direction by a device best seen in Figs. 1 and On the lower end of an upright rockshaft 26, mounted on the frame, is secured an arm 26 carryinga roller 26*, which bears on the face of a disk or plate 25 on the shaft 25 and on the upper end of said shaft 26 is secured an arm bearing a roller 26, which bears on a cam 27, fixed on the carrier 5 and moving therewith. This cam will have a form suited to the style or contour of the body of the hat on the block, and as the carrier turns slowly around the cam 27 and spring will move the cone 25 under the set-screw in the lever 24. in such a manner as to swing the frame 17, and with it the pouncing-roll, and cause the latter to follow that contour of the hat which would be seen in a sectional plane passing down longitudinally through the axis of the hat-body. The movement of the frame 17 is effected by the guiding-lever 24., which bears on the hat at its upper end. lVhen the larger part of the cone 25 is pushed under the lever, the fulcrum is on the hat and the frame 17 is pushed outwardly,carrying the pouncing-roll with it. On the other hand, the lever 24 serves to adapt the pouncing-roll to the elliptical contour of the hat-body, Fig. seen in a crosssection of the same; In this case the cone 25 becomes the fulcrum and the frame 17 is pushed outwardly by the higher part of the hat-body passing under the upper end of the lover. The end of the lever which bears on the hat may be padded or cushioned, if this be found necessary to prevent. injury to the hat.

I will now describe the mechanism which slowly rotates the carrier 5 through a quarter of a rotation, referring especially to Fig. 4.

Mounted loosely and rotatively on the shaft 12, between the miter-gear 14 thereon and the lower flanged end of the hollow shaft 5 is a spur-wheel 28, which gears with a pinion 29, fixed on the upper end of a long wheel-boss rotatable 011 a spindle on the frame, and fixed on the lower end of the said wheel-boss or sleeve is a spur-wheel 31, which gears with a pinion 32, rotatively mounted on the shaft 12. The pinion 32 is rigidly connected to or integral with a spur-wheel 33, and this spurwheel gears with a pinion 34,, mounted rotatively in a frame 35, adapted to turn or rotate about the shaft 12 as an axis. The pinion 31 is integral with a spur-wheel 36, which gears with a pinion 37, fixed on the shaft 12, and is integral also with a pinion 34 which gears with a spur-wheel 33 fixed in or to a part of the frame of the machine. This wheel 33 forms a step-bearing for the shaft 1.2.

The gearing just described being of a differential character, I will give the number of teeth which I prefer to employ in the several wheels as a guide in constructing the machine.

Wheel 28 has sixty teeth, wheel 29 has fifteen teeth, wheel 31 has fifty teeth, wheel 32 has twenty-five teeth, wheel 33 has thirtythree teeth, wheel 33 has thirty-two teeth, wheel 36 has thirty-two teeth, wheel 34 has sixteen teeth, and wheels 34. and 37 have each sixteen teeth. The pinion 37drives the wheel 36, which causes the frame to rotate about its axis owing to the pinion 34 revolving about the fixed wheel 33 but as the wheel 33 has one more tooth than the wheel 33 the wheel 33 will be driven slowly and will drive the wheel 28 through the wheels 29, 31, and 32. In order that the wheel 28 may drive the shaft 5 of the carrier 5, I provide a locking rod or bolt 38, mounted to slide vertically in guides in the flanges on the shaft 5 the lower end of said bolt being adapted to engage one of four holes or sockets 28 in the wheel 28, Figs. 3, at, and 4. The upper end of the bolt is coupled to one arm of a lever 39, Figs. 2 and 4, fulcrumed on a rigid operating-arm 40 on the carrier 5. The bolt may have on it a spring 38 to shoot it at the proper time.

I will now describe the means for shifting the driving-belt 3 to the tight pulley 3 and the means for automatically shifting said belt to the loose pulley 3 andthus stopping the machine when the pouncing operation is finished.

Mounted to slide longitudinally in bearings at the base of the frame is a belt-shifter a1,

havingan eye 41 at its extremity, through which the belt 3 plays, and coupled at its lower end to this sliding shifter by a collar 41 and link 42 is a shifting-lever 42, Figs. 1 and 1, fulcrumed on the frame 1. Fig. 1 shows the parts as they appear when the belt is on the loose pulley and the machine at rest. By pushing the upper end of the lever l2 over to the left (in Fig. 1) the belt 3 will be shifted onto the tight pulley and a strong spring 41." on the shifter tl will be compressed. To hold the lever in this position against the tension of the spring I employ a toggle device 43, the two links of which are pivoted one to the lever and the other to the main frame. \Vhen the shifting-lever is pushed over to the left, the toggle will assume the position seen in Fig. 1, and as the three pivotal points will then be in line the lever will be held. On one of the links is an arm tB which now stands upright and at right angles with the link. If this arm be pushed over to the right,

(in Fig. 1 the toggle will be broken and the spring 41 will instantly shift the belt over onto the loose pulley and stop the machine.

Means are provided for effecting the shift:

ing of the lever 42 and the release of the toggle 43 by the rotation of the carrier 5. This consists of two studs 44 and 45, (see Fig. 3,) which project out laterally from the base of the carrier 5. The stud 44 engages the end of the lever 42 and shifts the belt onto the tight pulley when the operator sets the carrier around to its operative position, and the stud 45 strikes and trips the toggle when the carrier shall have reached about the end of its travel.

The operation of the machine is as follows: The block with the hat upon it is secured to the block-shaft 6 by the clutch 8 and drawn up firmly to the chuck-plate 8 by the screw 9. In doing this the frame 17, carrying the pouncing-roll, is pushed back out of the way. The parts will then stand as in the drawings. The operator now grasps the operating-arm 40, depressing the lever 39 so as to withdraw the bolt 38 and free the carrier from the wheel 28, and swings the carrier around until the bolt engages the next socket 28 in the wheel 28 This will bring the tip or crown of the hat under the pouncing-roll. In doing this the stud 44 engages the lever 42 and moves it over in such a manner as to shift the belt 3 onto the tight pulley and to compress the spring on the shifter. The toggle 43 will also be set, as in Fig. 1, so as to hold the lever. The machine is now in motion, the pouncingroll and hat rotate axially and the hat swings round slowly about the axis of the carrier back to its first positions, the pouncing-roll passing thus over the surface of the hat from the tip to the band. When the parts return to their first position the pin or stud 45 strikes the upright arm of the toggle, releases the lever 42, and allows the spring 41 to instantly shift the belt and stop the machine.

I will now explain the preferred construction of the pouncing roll or head 18, with especial reference to Figs. 5, 5, and 5. In substance, this is a hollow roll with a removable sheet of sandpaper or the like wrapped about it, the ends of the strip of paper being tucked into a slot in the face of the roll and secured by a grip inside of the latter. Fig. 5 is an end view of the roll, showing the'grip open, and Fig. 5 is a similar view showing the grip closed. Fig. 5 is a longitudinal axial section of the roll. The shaft 18 has on its extremity an end plate 18, and the hollow roll 18 is open at its outer end and has a long internal boss and a longitudinal slot 18 in its rim. The plate 18 is furnished with a pin To open the clamp and at the same time bring the slot 18 opposite to the clamp, as in Fig. 5, there is a pin 18, projecting from the inner face of the closed end of the roll 18 and arranged to engage and open the jaw 18 when the roll is rotated about the shaft in the direction of the arrow in Fig.5. hen the ends of the sandpaper are properly inserted in the clamp, the spring 18 is allowed to close the clamp and rotate the roll 18 to the position seen in Fig. 5. The paper may be readily removed when worn out and replaced by a fresh sheet.

The pouneingroll rotates in the same direction as the hat on the block, and it is set obliquely to the axis of the hat and block in order to prevent the sandpaper at the ends of the roll from coming in contact with the convex surface of the hat and marking it.

The form of the guiding-lever 24 is indicated by dotted lines in Fig. 2. The purpose of the set-screw-24 in this lever is to adjust the pouncing-roll accurately to the surface of the hat.

The cam 27, which serves to adjust the pouncing-roll to the surface of the hat during the movement of the carrier 5, may be readily changed-that is, cams of different forms may be employed to suit hats of different forms and styles.
