MACHINE FOR SHRINKING FELT ARTICLES.
Application filed June 23, 1923. Serial No. 647,312.
'1'0 all whom it may concern: 7
Be it known that I, VVILLTAM A. LORENZ, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in a l\lachine for Shrinking Felt Articles, of which the following is a specification.
This invention relates to machines for shrinking and felting hat bats and the like and has as its aim to provide in an apparatus of this sort an improved arrangement of parts, and various features of novelty and advantage.
More particularly, the object of the invention is to provide a machine for shrinking and felting hat bats and the like which is characterized by its simplicity and economy in construction, its compactness in arrangement, its effectiveness in operation, and the ease and facility with'which certain adjustments may be made.
The above and other objects of the inven.
tion are obtained in the structure shown in the accompanying drawings, by way of illustration. In these drawings:
Figure 1 is a top plan view of the machine, a portion of one of the belts being broken away, and the pipes for delivering hot water onto the bats being omitted;
Fig. 2 is a side elevation of the machine; and
Fig. 3 is a diagrammatic showing of the machine in vertical section, on line 3-3 of Fig. 1.
Referring to the drawings in detail, the
machine is illustratedas having a frame of suitable construction and which, in the present instance, comprises a pair of side frames 10 tied together in any approved manner. circularly arranged within the frame are a plurality of guide rolls between which the bats are passed in an unrolled condition substantially in the path of a circle. In the present instance, the rolls are arranged in staggered relation so that, while the path of the bats is generally circular, it is also somewhat wavy, resulting in the bats being progressively bent to and fro as they are passed through the machine. These rolls support and guide one or morebelts,
in the present instance two such belts being shown by way of illustration; More articularly, the guide rolls consist of circularly arranged supporting rolls 1-1 constituting a circular track-way for the belts, and deflecting or wave rolls 12 interposed between the supporting rolls 11 and adapted to bear upon the belts and depress the same between the supporting rolls. One of the belts, which, in the present instance, is designated by the numeral 13, is a relatively short one and travels over and is directly supported by the supporting rolls 11. The other belt 1 1, for a portion of its length, overlies and engages the working face of the belt 13. Thus,- the belts are paired, so to speak, providing, what may be called, a double belt arrangement in that the belts travel together in a circular path between guide and deflecting or wave rolls.
In the present illustrative embodiment, the belt 13 at the forward end'of the machine, is passed about a roller 15 which is outside of the circle in which the guide rolls 11 and 12 are disposed so as to provide a horizontally extending receiving portion 16 on which the bats, such as the one indicated by the "numeral 17, are. placed. The outer belt 14: is in the form of a pair of loops, so
to speak, the inner loop being guided by the guide rolls 11 and 12, and the outer loop being carried about the rollers 18. This belt 1 1 has, at the forward end of the machine and immediately beneath the bat receiving portion of the belt 13, a horizontally extending delivery portion 19 from which the bats are taken after they pass through the machine and replaced by the operator on the receiving portion 16 of the belt 13. It will be noted that the horizontally extending portion 19 passes about a roller 18' spaced in advance of the roller 15. The belts may be placed under suitable tension in any desired manner, as by mounting the rollers 15 and 18' on weighted levers 23. Preferably. at least one of the belts is provided with a multiplicity of kneading knuckles so that, as the bats are passed through the machine, they are each kneaded or manipulated at a multiplicity of points, which action greatly facilitates the shrinking and felting operation. For example, the outer or working face of the belt 13 may be provided with such knuckles and, by preference, these knuckles are elastic, and-to this end they may be formed of rubber. The face of the belt 14 which engages the working face of the belt 13 in the present instance is smooth I but, if desired, the contacting faces of both of the belts 13 and 14 may be provided with elastic kneading knuckles.
By way of example, the gudgeons 25 of the supporing rolls 11 are shown as being journalled in suitably fixed bearings provided in the side frames 10, and the deflecting rolls 12 are rotatably supported in the free ends of crank levers 26 appropriately pivoted as, for instance, on the gudgeons 25 of the guide rolls. The levers 26 are pivotally adjusted so as to move the deflecting rolls towards and away from the supporting rolls in order to increase and decrease the waviness of the path which the bats take as they pass between these rolls. If the bats are relatively soft, the wave rolls are adjusted so that the bats are subjected to a .lesser bending movement to and fro, and if the bats are relatively hard, the wave rolls are brought in further between the supporting rolls so as to increase the \vaviness of the path and accelerate the shrinking and felting action. This adjustment of the wave rolls is accomplished by a pair of rotatable members, one on either-side of the machine, in the present instance these members being in the form of disks 27 journalled on the opposite ends of a shaft 28, journalled centrally of the machine. The disks, as will be seen most clearly from Fig. 2, are provided at their peripheries with radial slots 29 which slidingly receive the inner ends of the levers 26. For the purpose of simultaneously adjusting these disks 27, each is provided with asegment 30 n'ieshing with respective pinions 31 secured to a shaft 32 the end of which maybe squared to receive a handle whereby it may be turned. 1Vith the arrangement described, it will be clear that to adjust the wave rolls relative to the supporting ones and thereby vary the waviness of the path of the belts, it is merely necessary to turn the shaft 32 and thereby simultaneously swing the levers 26 to the desired extent. This adjustment can be made while the machine is operating and, therefore, without interrupting the manipulation of the bats within the machine.
Preferably, the guide rolls 11 and 12 are driven, and to this end, the gudgeons 25 of the supporting rolls have fixed to them gears 35 meshing with a large common gear 37 fixed to the shaft 28 and driven in any suitable manner, as by means of a drive gear 38. If desired, two gears 37 may be provided, one on either side of the machine, and alternate supporting rolls will be provided at one end with gears 35 meshing with one of these gears 37 and the intervening supporting rolls may be provided with gears 35 meshing with a gear 37 on the other side of the machine. Such an arrangement is shown in the drawings by way of illustra tion. The deflecting rolls may also be driven, and to this end I have shown these rolls as having gears 30. meshing with the gears 35.
A constant flow of scalding hot water is supplied to the bats as they are passed through the machine in order to obtain the desired shrinking action. In the present instance, this water is delivered from the pipes -11 down onto the top of the belts. In order that the water may reach the bats positioned between the belts, the belts are perforated, as indicated at 42. The water will run through the perforations of the belt which is uppermost but, as the perforations of one belt will rarely register with those of the lower belt, the water will not drain off immediately through the lower belt. I have found, in actual practice, that by thus providing the belts with holes or perforations, shrinking of the bat is greatly accelerated, because the hot water is properly supplied thereto.
The operation of the device will be clear from the foregoing description. It is understood that the bats are placed on the receiving portion 16 of the inner belt 13 and are then passed in a circular path between the supporting and deflecting rolls and, as the bats are so passed, they are repeatedly bent to and fro, subjected to a kneading action at a multiplicity of points, owing to the elastic knuckles on the belt 13, and are maintained in a saturated condition by the water delivered onto the belts and through the perforations thereof. After the bat has made one pass throughthe machine, the operator may take it from the portion 19 of the outer belt and position it again on the receiving portion 16 of the belt 13, and the operation may be repeated until the bat is shrunk to the desired extent.
It is, of course, obvious that my invention is susceptible of various modifications and changes which are within the spirit of the invention without departing from the scope of the following claims, it being understood that the present disclosure of my invention is by way of illustration only and it is not to be taken as restrictive of my conception.
