Definitions
- This invention relates to methods and means for making hat bodies.
- An object of this invention is to make felt hat bodies from the initial operation of depositing the for on a suitable form up to but not including the operation of felting the fur, and to do this without going through the manual operations which were heretofore necessary.
- Another object of this invention is to provide a machine in which hat-forming cones are mounted for movement one after another into a plurality of different positions or stations at which the various operations of depositing the fur to form a bat, wetting the bat, and removing the bat from the forming cone may be performed.
- a further object of this invention is to provide a machine of the kind referred to wherein the bat-forming, bat-wetting and bat-stripping operations respectively, or any of these, are performed automatically, preferably in timed sequential operation so that the bodies may be formed up to the felting stage without manual operation.
- an operator may be placed at each of the stations referred to to control the bat-forming, bat-wetting, and bat-stripping if desired, and even control the seriatim movements of the forming cones into and out of the various stations.
- the present invention includes the method of making hat bodies which consists in bringing the cones seriatim to a plurality of working positions and performing the operations at the various stations above referred to, or any group of them.
- Fig. 2 is a horizontal section of the station at which the fur is deposited on the forming cone, taken on the line 2-2 of Fig. i.
- Fig. 3 is a plan view of part of the machine, showing, in dot-and-dash lines, the gates at the fur-depositing station open to receive a cone and to permit the passage of the fur-laden cone to the wetting station.
- Fig. 4 is a horizontal section of part of the machine, taken on the line 4-4 of Fig. 1.
- Fig. 5 is a plan view of the machine showing the turntable for carrying the forming cones from station to station and omitting the showing of the fur-depositing and wetting mechanism.
- Fig. 6 is a side elevation of the part of the machine at the stripping station showing the wetted body in position to be stripped from the cone, and showing, in dot-and-dash lines, one position of the mechanism for removing the cone from the turntable preparatory to stripping the body from the cone.
- Fig. 7 is a view similar to Fig. 6, but showing the cone removed from the turntable and the body in the act of peeling or stripping from the cone.
- Fig. 8 is a diagrammatic view of the contact mechanism for automatically controlling the various operations on the machine.
- Fig. 9 is a horizontal section of the rotating table of the machine taken on line 9-9 of Fig. 1.
- the hat bodies are made on forming cones l0 made of perforated metal and having a rounded apex.
- a plurality of cones ID are employed, and these are moved from station to station, preferably automatically, to receive the fur, to have the hat of fur wetted, and to have the wet bat stripped from the cone.
- as many cones as desired may be employed, and these may be moved from station to station in any suitable way.
- the cones are mounted on a turntable H having rollers I 2 riding on a track on a main frame member l3 supported on standards l4 having feet I 5 which may set on a floor or on the bottom of 'a pit.
- the turntable H is preferably circular and at its center has a hub l6 passing through a bearing I! at the center of the main frame IS.
- the fur-depositing, wetting and stripping stations are evenly spaced around the main frame l3, and the turntable H is rotatable to bring each cone 16 to the various stations successively, and to leave the cones at the various stations for a suflicient time to permit the required operations to be performed.
- the turntable may, according to the present invention, be moved step-by-step for this purpose in any suitable way.
- the mechanism shown for accomplishing this step-by-step movement includes a ratchet wheel l3 having four teeth I3 a worm 30 driven by a worm wheel 3
- a worm 32 on a shaft of a motor 33.
- the motor 33 is constantly operating, and through the train of worm wheels and worms above-described slowly rotates the crank 26, with the result that the pawl 26 and its arm 22 are caused to swing about the pivot 23.
- the crank rotates in the direction of the arrow and, as it rotates from the position shown in Fig. 4, it moves toward the pivot point 23 and thereby causes the movement of the arm 22 to accelerate.
- the pawl 26 is moved 90 and, since it engages a tooth l3 on the ratchet I6, advances the turntable II for 90.
- the continued rotation of the crank 26 causes the direction of operation of the pawl arm 22 to be reversed, and during this time the crank pin is further removed from the pivot point 23, resultingin a slow return movement of the pawl. It is during the return movement of the pawl that the operations of depositing the fur, wetting the bat, and stripping the bat are performed. By the time these operations have been finished, the pawl 20 is again in position to engage a tooth

This invention relates to methods and means for making hat bodies.
An object of this invention is to make felt hat bodies from the initial operation of depositing the for on a suitable form up to but not including the operation of felting the fur, and to do this without going through the manual operations which were heretofore necessary.
Another object of this invention is to provide a machine in which hat-forming cones are mounted for movement one after another into a plurality of different positions or stations at which the various operations of depositing the fur to form a bat, wetting the bat, and removing the bat from the forming cone may be performed.
A further object of this invention is to provide a machine of the kind referred to wherein the bat-forming, bat-wetting and bat-stripping operations respectively, or any of these, are performed automatically, preferably in timed sequential operation so that the bodies may be formed up to the felting stage without manual operation.
In the broader aspects of the invention, an operator may be placed at each of the stations referred to to control the bat-forming, bat-wetting, and bat-stripping if desired, and even control the seriatim movements of the forming cones into and out of the various stations.
Accordingly, it will be understood that the present invention includes the method of making hat bodies which consists in bringing the cones seriatim to a plurality of working positions and performing the operations at the various stations above referred to, or any group of them.
The practical advantages of having a single unitary machine for performing the various operations in hat-making up to the operation of felting are self-evident, but it may be noted that a great saving is effected in labor expended, and, besides, when the operations are performed automatically, a greater uniformity of product is assured, and this may be maintained at whatever standard of quality is desired. In addition, the bodies may be made more rapidly by the machine provided by the present invention than if made by hand.
Other features and advantages will hereinafter appear.

According to the present invention, the hat bodies are made on forming cones l0 made of perforated metal and having a rounded apex.
A plurality of cones ID are employed, and these are moved from station to station, preferably automatically, to receive the fur, to have the hat of fur wetted, and to have the wet bat stripped from the cone. In the broader aspects of the invention, as many cones as desired may be employed, and these may be moved from station to station in any suitable way.
According to the present invention, however, the cones are mounted on a turntable H having rollers I 2 riding on a track on a main frame member l3 supported on standards l4 having feet I 5 which may set on a floor or on the bottom of 'a pit.
The turntable H is preferably circular and at its center has a hub l6 passing through a bearing I! at the center of the main frame IS.
The fur-depositing, wetting and stripping stations are evenly spaced around the main frame l3, and the turntable H is rotatable to bring each cone 16 to the various stations successively, and to leave the cones at the various stations for a suflicient time to permit the required operations to be performed.
The turntable may, according to the present invention, be moved step-by-step for this purpose in any suitable way. The mechanism shown for accomplishing this step-by-step movement includes a ratchet wheel l3 having four teeth I3 a worm 30 driven by a worm wheel 3| which,
in turn, is driven by a worm 32 on a shaft of a motor 33. The motor 33 is constantly operating, and through the train of worm wheels and worms above-described slowly rotates the crank 26, with the result that the pawl 26 and its arm 22 are caused to swing about the pivot 23. The crank rotates in the direction of the arrow and, as it rotates from the position shown in Fig. 4, it moves toward the pivot point 23 and thereby causes the movement of the arm 22 to accelerate. During this movement the pawl 26 is moved 90 and, since it engages a tooth l3 on the ratchet I6, advances the turntable II for 90. The continued rotation of the crank 26 causes the direction of operation of the pawl arm 22 to be reversed, and during this time the crank pin is further removed from the pivot point 23, resultingin a slow return movement of the pawl. It is during the return movement of the pawl that the operations of depositing the fur, wetting the bat, and stripping the bat are performed. By the time these operations have been finished, the pawl 20 is again in position to engage a tooth |3 on the ratchet.
The forming cones ID are not supported directly on the turntable II, but rather are elevated above it, on cylinders 34. At the top of each cylinder 34 there is a flange 35, see Figs. 1 and 7, on which there is mounted for rotation a ring 36. The inner surface of the ring is tapered downwardly and is adapted to engage a similarly shaped base 31 to which the cone I0 is secured. I
There is a frictional flt between the cone base 31 and the ring 36, so that each cone, with its base,
may be removed from the ring 36 when desired and yet, when it is supported on the ring, will rotate with it. As stated above, the machine of the presen invention has three operating stations. The furdepositing station is indicated generally by A, the
wetting station by B, and the stripping. station by C. As shown, these stations are spaced 90' apart around the main frame l3, but it should be understood that any suitable spacing of the stations may be employed. Also, as shown, there are four cones i6 and mounting structures therefor. These likewise are spaced 90 apart in the ma- .chine illustrated. At station D no work is performed, except that of moistening the cone so that when it arrives at station A the fur will adhere to it. For this purpose, there is provided at station .D a constantly operating spray 206 throwing a very little mist onto the cone.
Fur depositing At station A there is provided a chute 36, supported on standards 33, carried by the main frame, and this is connected to a stack 46 through which a predetermined quantity of fur' is allowed to fall at the proper time so that the fur may settle on the cone.
To insure the fur settling on the perforated cone ill in an even layer, suction is employed. For this purpose, the cylinder 34 which supports the cone and its base 31, is provided with a sheet metal box 4|, the top of which is open and has its edge lying close to the base 31 of the cone. At one side the box 4| has a duct 42 radially extending with relation to the cylinder 34 and the turntable The duct 42 has a flange 43 which engages a flange 44 on a duct 45 when the cone is located at station A. The duct 45 leads to the interior of an impeller-type blower 46 which has an exhaust duct 41. When the flanges 43 and 44 are engaged, the air is drawn down through the fur-depositing stack 46, the chute 36, through the perforated cone l6, through the box 4| and ducts 43 and 44 so that the falling fur is drawn upon and held to the cone in an even layer. A duct 45 is slidably mounted and resiliently urged by a spring 46 so that the flange 44 is engaged with the flange 43. When the turntable moves, however, the duct 45 is cammed back permitting the flange 43 to pass the flange 44.
During the depositing of the fur on the cone III at station A, the cone is completely enclosed by the chute, and means are provided by the present invention for permitting the cone to enter and leave the chute. For this purpose, side walls 43 of the chute are made in the form of gates. In the form of the invention herein shown, the gates 43 are eachpivoted on a shaft 56 on a solid rear portion 5| of the chute and close against a solid front wall 52 of the chute, see Figs. 2 and 3.
Each of the shafts 56 is provided with an arm 53.
and the arms 53 have links 54 connecting them to a lever 55 which in turn has a link 56 connecting it to an armature 51 of a solenoid 53. Before the turntable moves, the gates 43 are opened and they stay open while the cone on which fur was deposited travels from station A to station B, while the cone from which the bat has been stripped travels from station D to station A. The manner in which the solenoid 56 is operated will be described below.
While the cone is receiving the fur falling through the .chute 38, it is rotated so that the fur willbe deposited more evenly on it. For.
this purpose, the ring 36 on which the base 31 of the cone rests is provided with an annular row of teeth 53 meshing with a gear 60 on a shaft 6| journaled in the cylinder 34 and having a worm wheel 62 meshing with a worm 63 on the shaft of an electric motor 64, see Fig. 1. Each of the motors is connected by wires to brushes 65 in position to engage contacts 66 carried by the base l3, see Fig. 4, so that when any cone is at station A, the brushes engage the contacts and cause the motor associated with that particular cone to operate and rotate the cone.
It is desired to hold the fur in an even layer on the cone III while it travels from station to station, and for this purpose each of the boxes 4| is provided with a conduit 61 leading to the hub l6 of the turntable where the various conduits 61 join. The hub I6 is hollow and Joins with a hollow standard 63 at the center of the turntable and forming part of the base member, and this isconnected at the bottom by a duct 63 connected to a blower not shown. Air is continuously drawn through the'hollow standard 68 and conduit 61, and thus provides suction within the hollow cone in to hold the fur thereto.
Only a slight amount of suction is necessary station to station, but a large amount is needed carrying the counterweights 81.
during the fur-depositing operation at station A, and this is the reason for the provision of the blower 46.
In order that the air drawn in through the conduits 61 will not enter through the large. duct 42 while the cone is being transferred from one station to another, a flap valve 10 is provided in each conduit 42; the reduced atmospheric pressure in the box 4| causes the flap to remain against a stop 1| in closed position. Likewise, to prevent the blower 46 from drawing air back through the conduit 61 when in fur-depositing position, the latter is provided with a flap valve 12.
Fur wetting After the fur is deposited on the cone at station A, the turntable II moves and the cone is brought to station B where the fur which is deposited thereon and held thereon by suction, is wetted. At station B, there is provided a spraying device having a standard or support 14 secured to the main frame I3 and carrying at its upper end a hollow perforated cone 15. The cone 15 is mounted on a non-circular rod 16 slidably mounted in arms 11 at the upper .end of the bracket, and the rod 16 is provided with gear teeth 18 meshing with a gear 19 mounted on a shaft and also carrying a gear 8| meshing with a rack 82 connected to an arm 83 on a rock shaft 84. The rock shaft 84 has an arm 85 carrying a rod 86 having a. weight 81 thereon to counterbalance the weightof the rod 16. The rock shaft 84 has another arm 88 connected by a link 89 to an armature 90 of a solenoid 9 I. When the solenoid 9| is operated, the shaft 84 is rocked, causing the hollow cone 15 to be lowered over the bat on the cone I0 so that the fur, of which the bat is composed, will be held against shifting on the cone I0 during the spraying operation. Supported on the rod 16 is a spray head 92 having depending perforated tubes 93 located at spaced points around the hollow cone .15 and connected at their bottoms by a ring 94. The spray head 92 is connected by a flexible hose 95 to a fitting 96 carried by the bracket 14. This fitting is connected to a valve 91 and a supply hose 98. The valve 91 has an arm 99 connected to the rod 86 by a pin-and-slot connection I00 Thus, when the perforated cone 15 and the spray are lowered over the bat of fur on the cone I0 and approach their final position, the valve 91 is opened to cause water from the supply pipe 98 to be sprayed on the cone 15 and through the cone against the fur. The water supplied to the spray -is preferably boiling-hot. To prevent the water issuing from the spray pipes 93 from unneces-' ,sarily wetting the machinery, the cone and sprays are enclosed within a conical cover IOI.
During the spraying operation, air within the cone I0 is continually withdrawn and sucks through the bat the water which is sprayed thereon, thus insuring the complete and thorough wetting of the bat.
Water entering the box 4| passes down through theconduit 61 and hollow standard 68 to the conduit 69, and a suitable water trap not shown is provided between the conduit 69 and the blower which is also not shown. Surplus water flowing off the bat is allowed to flow into the box 4| 7 through one or more drain holes I02.
After the bat is fully wetted, current through the solenoid is interrupted allowing the weights turn movement, due to the fact that the valve 91 is spring-biased to off position, the valve is shut oil before the cone and spray have moved substantially'away from the bat. After the spray has moved up to its inactive position, the turntable and cone moves 90, and this brings the wetted bat to the stripping position C, see Fig. 5.
, Stripping As will be seen from a comparison of Figs. 6 and 7 at station C, the cone I0 with its base 31 is picked up from the cylinder 34 and the turntable and is flipped over so that the wetted bat may be stripped from the cone.
To permit this to be done, the base 31, as stated above, has va-frictional fit in the ring 36 so that the cone and its base may be. lifted out of the ring. To do this, a fork I03 is provided and is so positioned that its tines may enter an annular groove I04 in the base 31 of the cone. In
.doing so, the tines expand, and when they are located within the groove I04, they firmly grip the base and hold it against movement relative to the fork. The fork is pivotally mounted on a shaft I05 carried by the upper end of a rocking frame I06 which in turn is pivoted at I01 on the base of the machine. The rocking frame is counterbalanced by weights I08 so as to normally occupy the position shown in Fig. 6. When the wetted cone arrives at station C, the frame I06 is pulled to the right as shown in Fig. 6, by a link I09 connected to the armature IIO of a solenoid III so as to occupy the position shown in dot-and-dash lines with the fork I03 gripping the base of the cone.
This rocking movement is such that the base is tilted up on one side so that it occupies the position shown in dot-and-dash lines in Fig. 6. 40 With the cone thus grasped, the rocking frame I06 returns to its full-line position shown in Fig. 6, and, at the same' time, the fork I03 is rocked on the axis of the shaft I05 so that when the frame I06 reaches the position shown in Fig. {5 7, the cone has been flipped over and is upside down. To thus fiip over the cone, the shaft I05 is provided with a pinion II2 engaged by a rack 3 connected to an armature H4 of a solenoid H6, and also connected to a rod H6 54 v having a spring II1 tending to return the rod, armature and rack to their normal positions shown in Fig. 6. When the cone is flipped over,
-a loose ring II8 surrounding the base of the cone and held thereto by pin-and-slot connections 9, is allowed to fall by gravity. This causes the lower. edge of the wetted bat to be turned outwardly and the weight of it causes it to turn downwardly as shown in Fig. '7. From this position, the body strips itself by gravity 60 from the cone and in doing so turns inside out and falls into a suitable receptacle.
To guide the fork I03 into proper position in the groove I04, the frame I3 of the machine has a pair of stationary arms I2I on which the as lower edge of the tines rest. I When the fork swings from the dot-and-dash line position to the dotted line position shown in Fig. 6, an arm I22 on the fork engages a pin I23 on the swing-' ing frame. 70
After the body has stripped from the cone I0 with the parts shown in the positions they occupy in Fig. 7, the solenoid H5 is deenergized, permitting the cone and the fork to swing back and at the same time the solenoid III is energlued to swing the rocking frame I! back toward the frame of the machine. when the parts reach this position, the base 31 of the cone is deposited on the ring I. and the fork I03 withdraws from the annular groove I02 leaving the cone in proper position on the turntable. When this operation as well as the fur-depositing and wetting operations have been concluded, the table turns and this brings the cone ill, from which the body had previously been stripped, to station D where it remains out of service until it is moved to station A. While it is at station I), the cone may be moistened by the spray 2, so that it will be sufilciently damp to receive the fur.
In the above description it has been stated that the gates 49 at station A, the sprinkler 13 at station B, and the stripping mechanism at,
station C are operated by solenoids. It should be imderstood, however, that in the broader aspects of this invention, these parts may be operated in any suitable manner and by any suitable means, and, in fact, they may be operated by hand having an operator at each station to open and close the gates and to raise and lower the sprinkler, and to remove the cone from the'turntable, if desired. However, it is preferable and advantageous to have these operations performed automatically and in coordination with the movement of the turntable and with the operation of each other. For this purpose, electrical means are provided for operating the various mechanisms in coordination with the means for advancing one cone after another through the diflerent stations.
Accordingly, as shown in Fig. l, and as diagrammatically indicated in Fig. 8, the shaft 21, which controls the step-by-step movement of the turntable, carries a contact drum I 24. Current is supplied to the contact drum from a main supply line I25, through a brush I26 to a sleeve I21 carrying a plurality of contact disks adapted to be engaged by contact fingers leading to the various solenoids. As shown in Fig. 8, there is a contact disk I having a raised contact portion for engaging a contact finger I29, connected by a wire I to the solenoid 58 which opens and closes the gates 49. This raised part of the disk I28 occupies that portion of the disk which is located'in position to be engaged by the contact finger I29 while the turntable is moving from one position to another. On the sleeve I21 there is another disk III having a raised portion adapted to engage a contact finger I32 connected by a wire I" to the solenoid 9| controlling the spray. There is another disk I34 carried by the sleeve I21 having a raised portion adapted to engage a contact finger I35 connected by a wire I" to the solenoid III which controls the movement of the swinging frame I08 of the conefiipping mechanism. There are two raised portions on this disk I at spaced intervals, one
to cause the rocking frame to be moved in so that the fork I02 may receive the cone, and another raised portion to mo e the rocking frame in when the fork lll is to redeposit the cone on the turntable. There is another disk I31 carried by the sleeve I21 and this is adapted to engage a contact finger I38 connected by a wire I to the solenoid IIiwhich controls the rotation of the fork Illlfrom the position shown in Fig. 6 to that shown in Fig. 1. Each of the solenoids is connected by return wires to the return supply line I" on the main source of supply.
It will be noted that all of the raised portions ing the movement of the turntable from one.
position to another. and that this movement,
because of the accelerated action produced by the crank 26- and slotted arm 22, occupies only one-quarter of the rotation of the shaft 21.
The main feed lines I25 aand I" are connected to a source of current supply by a. switch I, see Fig. 1.
To avoid a condition where the suction effect produced within the hollow cones would practically be destroyed at the time and by the removal of the body and cone from the turntable at the stripping station, a stationary sleeve I42 is provided within the hollow standards .58 and this extends up into the turntable structure. It has two holes so disposed that one aligns with the conduits 81, leading to the cone which is in fur-receiving position, and the other aligns with the cone which is in bat-wetting position. The solid walls of the sleeve I42 match up with the conduit 61 which lead to the "cone at the stripping station and the cone-spraying station and thus prevent air entering the open box H or the empty cone at station D from afiecting the suction within the other cones.
Variations and modifications may be made within the scope of this invention and portions of the improvements may be used without others.
