HAT-POUNCING MACHINE.

SPECIFICATION forming part of Letters Patent No. 540,445, dated June 4, 1895. Application filed October 16. 1 893- I Serial No. 488,206. (No model.)

T on whom it may 00700677215 Be it known that I, JOHN B. HOWE. a citizen of the United States, and a resident of Danbnry,in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Hat-Pounoing Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in hat-pouncing machines, and is designed to treat a large variety of hats, both as to size and quality; and has for its object to provide a durable and light running machine which will not require the services of a skilled operator; to provide mechanism whereby the speed of the pouncerheights of hats; and to provide means whereby the lineof travel of the pouncer over the hat is both circular and oblique with relation to the center thereof, thus bringing the entire surface of the sand paper into play during the pouncing of each hat.

For the purpose of fully illustrating my improvements, I show them applied to a machine which is similar in many respects to that shown in my former patent, No. 490,788.

In the drawings, Figure 1 is a side elevation of a pouncing-machineembodying my improvements, a small portion of the framework being broken away. Fig.2 is an elevation taken from an opposite side from that of Fig. 1, the hat being omitted. Fig. 3 is a cross-section of the machine on the line 1) o of Fig. 1. Fig. 4 is a cross-section on theline w w of Fig. 1. Fig. 5 is an enlarged longitudinal vertical section of the tension on the line 00 0c of Fig. 6. Fig. 6 is a cross-section on the line y y of Fig. 5. Fig. 7 is a similar cross-section, showing the parts in a changed position. Fig. 8 is a side elevation of a friction-wheel which I employon the tension mechanism and which is shown in Fig. 5. Fig. 9 is a plan. view, partly in section, of the pouncer-lever, head, and other attached parts. Fig.

10 is a'detached side view of the pouncerhead and hat, showing the line of travel of the pouncer over the hat. Figs. 11, 12, 13,

and 14 show detached views, in detail, of

parts attached to the pouncer-lever, Fig. 13 being a section taken on the line 2* z of Fig. 9. Fig. 15 shows aplan view of the machine, the pouncer-head, lever, and connecting parts being removed. Fig. 16 is a detailed perspective view of the bracket, having a slide mounted therein and pertaining to the speedregulating mechanism. Fig. 17 is a detached View of the lever 90 used in connection with the clutch mechanism.

Fig. 18 is a longitudinal vertical section on a line u u of Fig. 15.

Similar numerals indicate like or corresponding parts in all the views of the drawings.

The main frame 1 of the machine is similar in essential features to that shown in my former patent above mentioned, as are also the

main drivingshafts

2 and 3, and the oval lathe 4. A bevel gear 5 upon the shaft 2 meshes shaft 12, and splined thereto so as to be ro-,

tated with such shaft, and yet have an endwise movement thereon. Said wheel 11 is also provided with the elongated hub 11 which latter extends through a hole provided in the,

upper end of the slide 14 and is secured there to by means of the collar 11 This arrangement allows said friction wheel to freely rotate, while its movements over the face of the disk wheel 10, to and from the center thereof controlled by the crank 16 through the medium of the rod 15, the rear end of which is operatively connected to the before mentioned guided slide 14 (see detailed Fig. 16) which in turn carries said friction wheel 11. Upon the shaft 12 is keyed a bevel pinion 17 which to regulate the speed of the pouncer 23, is

meshes with and drives another pinion 18 on a short vertical shaft 19; and, attached to said vertical shaft 19 is a short flexible shaft 19 which is connected with the shaft 36 in the pouncing lever 10, and serves to drive the pouncing head.

It will be seen from the foregoing, that if it is desired to either increaseor decrease the speed of the pouncer head, the operator has simply to manipulate the crank 16, a movement of which toward the rear, as in Fig. 1,

will increase the speed of' the pouncer head, while a movement toward the front will have an opposite efiect. This change of speed is essential in changing from one grade of hats,

to another.

Upon the feed shaft 8 I place an angle arm 21 which is provided with a cam groove 20 in the hub thereof. Said arm as will be seen is splined to its shaft and is subject to a sliding movement thereon by reason of its cam groove 20 engaging a terminal pin 20 of a stud 20 made fast to the frame. The purpose of this angle arm is to support the pouncer lever and head and control them in one of their movements. It will thus be seen that any rotary movement of the shaft will be imparted to the angle arm, and that a sliding movement of the arm by reason of said rotary movement, and the engagement of its cam groove with the before mentioned terminal pin, will be communicated to the pouncer head operating upon the hat. The feed shaft 8 begins its slow rotary movement from the position shown in Fig. 1 (see also Fig. 10) in which views it will be observed that the rotary pouncer head begins its operation central with the center of the top of the hat crown. The shaft 8 in its movement rotates to the right, viewing Fig. 1 in front at left end see also Fig. 4, carrying with it the angle arm, pouncer lever, head, the. As said head travels over upon the side of the hat,it will be observed, (see circles Fig. 10) that its center has been drawn rearward from the center of the hat by reason of the connection between the cam groove in the angle arm, and the stud, as previouslydescribed. It will also be understood that the practical amount of work of the head is increased upon the sides of the hat crown since the head is then cutting away from its center. This is advantageous since the hat requires more work upon its sides than upon the top and quarters.

In order to properly adjust the pouncer head 23, and its lever to the various heights of hats, I have provided the following means viz: Upon the angle arm 21 is secured a bracket 22 (Figs. 2 and 9) which is provided with

arms

22 and 22*. To the arm 22 is pivotally connected an operating lever 23 shown in Figs. 2 and 13, which is provided with orifices 2i and 25, to receive the hub 19 of the pouncer lever, and fulcrum pin 25 respectively, for the purpose of permitting a length- -.Wise movement of the operating lever 23.

and 27. Around the stud 26 is coiled a spring 26*" which abuts against the arm 22", the latter being provided with a series of notches in which the stud 27 may be seated. It will be seen that a forward movement of said lever 28 will disengage the stud 27 from its seat, after which said lever may be tilted on its pin 25, so as to adjust the hinge connection of the pouncer lever 19 to and from the feed shaft 8. The angle arm 21 is provided with an oblong opening 28; and fitted loosely therein is asliding block 29 to which is fixed a stationary shaft 30, forming a fulcrum for the pouncer lever. In order to counterbalance the weight of the pouncer lever 10, and secure any required pressure of the pouncer upon the hat at the beginning of an operation, and to force the pouncer from the hat at the completion of the operation, I have provided mechanism, as shown in Fig. 9, consisting of a torsional spring 3i, one end of which is secured to a collar 32, arranged upon the hub 1.) of the pouncer lever, and the other end of which is secured to a lever 33 provided with a hub extending around the fixed shaft and meeting the hub of the pouncer lever about midway, the spring being disposed to encircle the two. In order to retain the desired tension ofthe spring, I have titted to the lever 33, in a suitable guide-way Fig. 11 a spring-actuated slide 34 having a lug Fig. 12 which engages the teeth of the ratchet 35 fixed to the said shaft 30. It will be seen that by the handle the lever 33 can be turned in either direction and can be secured at any point by means of the above mentioned locking slide. By turning the handle to the left, as shown in Fig. 2, the tension of the spring is increased, thus lessening the pressure of the pouncer upon the hat; whereas by turning the handle in the opposite direction, the tension is decreased, and the pressure upon the hat increased. The above means of adjustment dispense with a multiplicity of. weights, and insure an even and accurate adjustment of the pouncer upon the hat.

The pouncer head 23, is mounted upon a hinged bifurcated pouncing lever 19, and re ceives its power from the flexible shaft 1S) through a short shaft 36 which is housed within the shank 36 of the head. This shaft is provided atone end with a knuckle joint, by means of which the flexible shaft is connected thereto, and at the oppositeend it carries a bevel pinion meshing with the bevel pinion of the head.

It will be observed that the shank 36 of the pouncer head 23" is loosely fitted into a bore of the lever 19 and is secured therein by means of a collar 37 upon the end of said shank. This construction permits a slight: oscillatory movement of the pouncer head and shank 36 within the lever 19, so as to more readily adapt its position to the conformation of the hat. In order to steady the pouncer and prevent it from tilting while pouncing the side of the hat, I employ a spring parallel with the surface of the hat crown while pouncing the quarters and sides thereof, said spring 38 being connected at one end to a collar 37 upon the pouncing lever, and to a stud 39 upon the pouncer head. The tension upon this spring 38 may be adjusted at will to accommodate the shape of the hat crowns, by the collar 37. (See Fig. 10.)

From the above description it will'be seen that as the pouncer descends from the tip to the side crown of the hat there is a tendency upon the part of the counterbalancing de vices above described to decrease the pressure upon the hat owing to the fact that the weight of the pouncing, head, already partially overcome by the counterbalancing device, is no longer exerted on the hat in a vertical plane; whereas the pressure should be increased since the hat requires more Work upon the side than the tip, and therefore I have provided automatic means (see Figs. 5, 6, and 7) for increasing the pressure as desired upon the side crown of the hat as the pouncer head descends from the tip along the side crown thereof in its operation, the construction being as follows: On the vertical shaft 3 is a Worm 4O transmitting power to a gear 41, upon a shaft 42, which is hung in a bracket 42 near one end, and is journaled in a suitablebearing in the-bracket 9 at the other end. The gear 41 which is loose upon the shaft is provided with a hub having an internal clutch face 43' forming one member of a clutch, of which the other member is shown at 44 and is 'splined to the shaft by a operation.

key 44 This clutch forms the operating connection between the shaft and the driving mechanism. 44 of the clutch is loosely journaled in the end of a sleeve 45 which is splined to a sleeve 46 loose upon the shaft and having an arm 47. The sleeve 45 is provided with a cam groove 45 to receive a guide-pie 46, said pin being firmly held in a projection from the bracket 42*. The sleeve 46 is loose upon the shaft and may be rocked in either direction by means of the rod 48. (See Figs. 4, 5, 6, and 7.) Said rod is connected with a lug 49, on the arm 50, of the shaft 8. It will thus be seen that when the arm 50 is elevated to a vertical position as in Figs. 1, 2 and 4, the rod will be forced down,and by means of its conn ection with the arm 47, will operate the latter together with its sleeve, and the sleeve 45 mounted thereon, thereby causing the engagement of the clutch members. At the lower end of the rod 48 is suspended a weight 51 which serves to counterbalance the weight of the bifurcated arm 50 and the pouncing lever supported therein while descending in their The connection between the rod 48 and the arm 47, (see'Figs. 1, 6 and 7) consists of a sleeve 48 loosely secured within a slot 47 a of said arm 47, and is provided with a hole through which the rod is'free to move The extremity of the member vertically. Upon the rod, above and below the sleeve 48 are secured adjustable collars 48 which engage said sleeve and operate the arm 47 at each movement of the before mentioned rod 48.

Referring to Figs. 1 and 4, it will be clear that the adjustable collars 48 do not fit snugly against the sleeve 48 and may be set at any desired distance apart, thus allowing the lat ter a slight movement while the rod travels a considerable distance, the arm of the sleeve 46 being engaged only at the extremities of the movement of the rod 48.

Upon the shaft42, is a sleeve 52 secured in place by set screw 53, and upon this sleeve is mounted a winding drum 54 which supports a loosely mounted wheel or disk 55 provided a clutch, and adjacent thereto is a sleeve a lever 62. The lower end of this lever is hinged to a rod 63 suitably secured to the framework, and the other end of the lever is attached to a sleeve 64 having a pin fitting in a groove cam 65 upon the rock shaft 66 which is parallel with the shaft 8. It will be seen that a partial rotation of this rock-shaft 66, and the cam 65 will operate the sleeve 64 andits lever 62, bearing the roller 62, which engages collar 61 of the clutch sleeve 60, thereby causing the engagement and disengagement of the clutch members thus making or breaking the connection between the shaft 42 and the winding drum 54.

A smallchain 67 is secured at one end to the pouncing lever, passes over a recessed wheel 68 on the shaft 8, extends downward and around within the groove of the before mentioned wheel or disk 55, and is secured'to the said wheel at 69. The function of this chain is to communicate pressure to the pouncer lever from the winding drum as follows: With the parts of the machine in the positions shown in Fig. 1, the several clutches being connected, the rotation of the shaft 42 in direction of the arrow, Figs. 5 and 6, will communicate motion to the winding drum, thereby winding the torsional spring 57 causing an increased pressure which will be conveyedjto the pouncing head through the medium of the disk and chain which latter will be wound upon the disk. This pressure will obviously increase with the rotation of shaft 42 and the drum, by reason of connections as previously described, and the spring will tighten until the completion of the pouncing operation, when the arm 50 will engage the stud on the trip-lever 70, (see Fig. 4) thereby disengaging the latter from the notched disk 70 of the shaft 66, when the said shaft will by means of a weight 71 secured thereto, rock back to its normal position as previously described. The connection of the lever 62 with cam 65 on shaft 66 will cause the disengagement of the clutch sleeve 60 from the winding drum, the release of the latter allowing the retraction of the before-mentioned spring 57. During this time the other clutch 43 44 on the same shaft is being opened by the connection of the rod 48 with the arm 47, whereby at the completion of each operation these parts hecome idle and the gear 41 revolves loosely upon its shaft 42. The function of the enlargement 56 on the disk 55 is to insure the retraction of the disk as the pouncing lever is raised on the beginning of the pouncing operation. ferent heights of hats and yet retain the same relative tension for each, and it will be seen that when the lever is raised and the pad is placed on top of the hat, the weight upon the disk will be suificient to take up any slack in the chain and maintain the winding drum 54 at a certain position with relation to the disk 55.

In order to prevent the shaft 42 from retraction at the moment of the disengagement of the clutch members, I have placed at one end of the shaft a friction clutch (Figs. 5 and 8) consisting of a housing 72 which is secured by a set-screw to the shaft, and a disk 73 fitting within the housing and having inclined notches on its periphery, forming between the disk and housing a series of recesses in which are arranged small rollers 75. The disk 73 is provided with a hub extending outward from the shaft and keyed to a stationary part of the framework 1, whereby the disk is fixed and the clutch just described will allow the shaft to revolve in one direction only.

Upon the main driving shaft 2 is loosely mounted a driving wheel 76 which is adapted to be locked to the shaft by a common form of friction clutch not shown in detail. The means for operating the slidable member 76 of. this clutch comprise a hand crank 77 secured to a rock shaft 78, said shaft being mounted in brackets 78 of the frame and bears a cam 7 8 the groove of which is engaged by a stud 79 of one of said brackets 78. (See Fig. 15.) A vertical lever 79 pivoted to a stud of the frame connects this rock shaft with one end of a horizontal lever 90, the 0pposite end being pivoted to the machine at 90. Said lever 90 bears a stud 91 which is connected with the movable member of the clutch.

In order to operate the slides of the oval lathe and secure a proper adjustment of the same, I fasten upon the shaft 8 an adjustable It is necessary to provide for dif cam 96 connected with a rack 95 which is, in turn, connected with a small pinion 94 on the rock shaft 93 journaled in suitable brackets of the framework, and upon this rock shaft is a grooved cam 92 engaging a pin upon one end of the lever 92; said lever being pivoted at 92 to the machine and having its opposite end 92 connected with the slide ofthe lathe.

It will be manifest from the foregoing that as the shaft turns, the connections described ,will cause the lathe to be thrown from its center at any predetermined time.

The feed shaft 8 is driven from the vertical shaft 7 at the top of which latter is a worm 100 which meshes with a worm gear 101 upon a horizontal shaft 102, the latter carrying at its outer end a worm 103 meshing with the gear 104 upon a short vertical shaft 105. The shaft 105 is provided at its upper end with a bevel pinion 106 meshing with the pinion 107 of the sleeve 108 on the feed shaft 8. Said sleeve is loose upon the shaft and is free to rotate thereon with aslow movement at such times when the remainder of the machine is in operation. Upon the inner end of this sleeve is formed one member 108 of a clutch of which the other and slidable member 109 is splined to the shaft. (See Figs. 1 and 18.) It will be seen from this construction that the sleeve 108 can be running while the shaft 8 jonrnaled therein may be idle, and that the slidable clutch member 109 is operated by reason of its lever connection 110 with a cam 111 upon the rock shaft 66, and further, that by said operation and engagement of the movable clutch member a slow rotary movement is imparted to the feed shaft 8, which in its travel carries with it the angle arm 21 and its connecting parts, including the pouncer head, together with the arm 50 and its operating connections. It will be understood that the rotary movement of the shaft 8 is but one quarter of a rotation, which is sufficient to move the pouncing head down'from the tip to the brim of a hat.

The operation of the machine is as follows: The parts are in the position shown in Figs. land 4, that is, the

arms

50 and 21 are in a vertical position, thus holding the pouncing head upon the tip of the hat. Shaft 66 has been turned by the crank ac and held by the trip lever 70, which turning has closed the clutch 108 109, through lever 110 and cam 111, and has closed the clutch 54-60, through lever 62 and cam 65. The vertical position of arm 50 necessitates closing of clutch 43+44 through cam 45, arm 47, rod 48 and crank 49. With the parts thus positioned, the machine is started by turning crank 77, Fig. 2, thus operating lever 79 from pin 79, and through said lever and intermediate devices closing the clutch 76-76. When the machine is thus started the main shaft rotates the lathe shaft 3 carrying the hat-block by the bevel gearing, the shaft 3, by worm 40, worm-wheel 41 and clutch 43-44, transmitting motion to shaft 42, which in turn, imparts motion to IIO drum 54 and disk 55, through theclutch member 60. p The main-shaft also rotates shaft 7, through bevel gearing 5'-6, which shaft 7 in turn imparts a slow rotating movement to shaft 8, through the worm and worm-wheel 100' and 101 and other intermediate gearing to the'clutch 108 109; The shaft 7 also imparts rotary motion to the flexible shaft 19 through the friction wheels '10 andjll, shaft 12 and gearing to shaft 19, which latter is .connected to said flexible" shaft, the latter shaft being connectedto shaft 36 which latter crown, the tension device on the pouncing lever will overcome the weight of the head, because such weight is longer exerted in a vertical plane, with the. result that such head will fly away from the hat-body. To overcome this effect and to place an increased pressure on the side-crown where it is most needed, the

mechanism shown in Fig. 5 is provided, and operates as follows: As soon as the devices above described are'started to operate, the clutch-part rotates the drum 54 slowly in the direction of the arrow, Fig. 5, gradually wrapping the spring 57 on the drum, the spring in turn rotating the disk 55 in the direction of arrow, Fig. 6, thus gradually winding chain 67 on the disk in the groove thereof, the chain passing over deflecting wheel 68 and connecting with the pouncing lever, as shown in Fig. 1. Manifestly, as the arm 50 moves in a direction opposite to the pull ex-' erted by the drum on the chain, the latter will draw the pouncing head against the side-' crown with a gradually increasing though yielding pressure. When the arm 50 has carriedthe pouncing head down to the base of the hat-crown, said arm strikes a pin on the tripping lever '70, the outer end of which, upon sufficient pressure, releases the shaft 66, which rocks back to its normal position through the medium of the weight 71. As the shaft 66 assumes its normal position, it causes, through i the described mechanism the opening of the clutches 60-54'and 108 409, thus stopping rotation of shaft 8 and releasing the drum. The tripping of lever 70 is the signal for the operator to reverse the motion of the shaft 78 by crank 77 and thus stop the machine. It will be observed that the downward movement of arm 50 gradually elevates rod 48, the collars on which allow, according to adjustment, a predetermined movement without affecting the sleeve 46. Eventually, however,

the same, turning the sleeve 45 carrying the cam groove 45*, until, as the arm 50 reaches its lower limit, the cam groove 45 and pin 46 have caused the retraction of v the clutch-member 44, thus stopping shaft 42. The springdrum flies back to its normal position and unwinds the chain from disk 55, thus'releasing the pouncing lever of pressure. The counterbalancing device on the lever causes the latter to carry its head away from the hat, and the weight 51, at the lower end of rod 48, exerts a pullto return arm 50 to its vertical position. The same movement of rod 48 causes the upper collar 48" to act on arm 47 and force it to its lowest position, which movement, through the described means again closes the clutch 4344 in readiness for operation. Veight 56 takes up any slack in chain 67 which may occur after the parts have assumed their normal inoperative position; and the gravity of the pouncing head reasserts itself, as the arm 50 assumes its vertical position, and is counterbalanced by the tension device carried by the pouncing lever.
