MACHINE FOR MANUFACTURING HARD FIBER. IN FLAT FORM.

Specification of Letters Patent.

Patented June 20, 1911.

Application filed November 29, 1910. Serial No. 594,642.

To all whom it may concern:

Be it known that I, GEORGE WV. TEMPLE, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and use ful Machine for Manufacturing I-Iard Fiber in Flat Form, of which the following is a specification.

My invention relates to a new and useful machine for manufacturing hard fiber in flat form and consists of means for suitably feeding the material in a flat condition to a reciprocating support, with suitable means for taking up or providing for the slack at each end of the movement of the table in order that'there will be no inequalities in the finished product nor waste of the material.

It further consists in providing a novel feeding device which is automatically elevated as the material is fed to the reciprocating support and means for supporting the said feeding device.

It further consists of novel means for gripping the material in order to take up the slack.

It further consists of novel means for holding the feeding device in elevated position.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

Figure 1 represents a sectional view on line wa', Fig. 5, showing the machine for manufacturing hard fiber in one form, embodying my invention. Fig. 2 represents, in elevation, a portion of the parts shown in Fig. 1, showing the same in a different position. Fig. 3 represents a sectional view on line yg Fig. 5, of a portion of the mechanism for supporting the feeding device. Fig. 4 represents a plan view in detached position, of the means employed for gripping the material. Fig. 5 represents a sectional view on line zz, Fig. 1. Fig. 6 represents a plan view of a portion of the machine showing the device for shifting the belt in order to provide for the reciprocations of the table or support. Fig. 7 represents a sectional view on line a-a, Fig. 5. Fig. 8 represents a perspective view of one corner of the table or support showing a latch employed. Fig. 9 represents a side elevation of a guide employed, in detached position. Fig. 10 represents an elevation of a collar or tumbler employed, in detached position.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings: In the manufacture of hard fiber as heretofore employed, the material is wrapped upon a cylinder and chemically treated in order that the layers of the material will be suitably united to form the finished product. After the same is in proper condition, the material is cut in order to remove the same from the cylinder and as the material has hardened it will be in a curved condition. It is thus necessary in order to adapt the same for proper use, to flatten the material by any suitable means. This causes a buckling or separation of the layers of fiber from each other or renders the ends thereof unequal, which must thereafter be cut, so resulting in a loss of material and a considerable waste thereof.

My invention is designed to overcome these defects and to form the material initially flat so that none of the material is wasted and a perfect product results.

In the drawings I have shown one embodiment of my invention which will operate successfully in practice, but it will be evident that changes may be made in the construction, the arrangement of the parts may be varied and other instrumentalities may be employed which will come within the scope of the invention and I do not there fore desire to be limited in every instance to the exact form as herein shown and described, but desire to make such changes as may be necessary. 7

1 designates the frame of the machine, which may be of any suitable construction and which is adapted to support the various parts of the mechanism which are mounted thereupon in any suitable or desired manner. Suitably journaled in the frame 1 is the power shaft 2, to which power may be applied in any desired manner, in order that with respect to each other that one or the other will always be in engagement with the tight pulley so that by shifting these belts, by any suitable means, the shaft 2 will be rotated first in one direction and then in the other.

8 designates a gear suitably carried on the shaft 2 which is in mesh with a rack 9 carried by a table or support 10 which is guided or movably supported upon the frame 1 in any suitable manner, in order that the movement of the shaft 2, through the medium of the gear 8 and rack 9, will reciprocate the said support or table 10 backward and forward on the guides and beneath the feeding means. In the present instance, the table is supplied or provided with a groove or depression 11 adjacent the edges thereof which is adapted to receive the excess chemical or compounds, as will be hereinafter described. In order to provide for the shifting of the belts 6 and 7, I have here shown mounted upon the table, adjacent the opposite ends thereof, the pins 12 and 13, which are movable in the path of and adapted to engage with one arm of a bell crank lever 14, pivotally supported at 15, the opposite end of said bell crank lever being in engagement or connected with a rod or bar 16, having means for engagement with the belts 6 and 7, in the present instance said rod being provided with lugs or fingers 17 for this purpose. It will be understood as the table 10 reciprocates, that at the proper time one of the pins 12 or 13 reaches the arm of the bell crank lever 14 and will move the same in the direction in which the table 10 is moving. This movement of the lever 14 shifts the belts 6 and 7 and, as shown in Figs. 5 and 6, the belts being so shifted in order that the belt 6 is in engagement with the pulley 3 loose on the shaft 2 and the belt 7 is in engagement with the pulley 4, fixed upon the shaft 2. This will cause the belt 7 to actuate the pulley 4 and shaft 2 in order to cause the latter to rotate in a reverse direction and thus move the table 10 in the opposite direction from its position seen in said Fig. 6, this movement continuing until the pin 13 at the opposite end of the table 10 strikes the arm of the bell crank lever 14, which will reverse the position thereof, pulling over the belts 6 and 7 when the belt 7 will be in engagement with the pulley 5 loose upon the shaft 2, while the belt 6 is in engagement with the tight pulley 4, whereupon the rotation of the shaft 2 is reversed in order to cause the table 10 to move in the opposite direction until it again reaches the position seen in Fig. 6, when the pin 12 actuates the bell crank lever 14 to again reverse the movement of said table 10. Carried upon a suitable portion of the frame 1 above the reciprocating support or table 10, in the present in stance, are brackets 18 which are suitably positioned and formed to receive and support a bar or roller 19 which carries a roll of the material 20, to be treated.

21 and 22 designate suitable rollers carried in a suitable manner upon the frame and 23 designates a tank suitably supported by the frame 1 with respect to the rollers 21 and 22 and which is adapted to receive the chemical compound or solution 24 with which the material 20 is treated in order to saturate the same and impregnate it with suitable material or chemicals in order that the same will be in condition to accomplish the result desired. Pivotally supported in the tank 23 is a' gate 25, which is provided with bars 26 and also with the two bars 27, which act as scrapers and which are situated adjacent the upper end portion of the gate 25, it being understood that the ma terial from the roller 19 is passed over the roller 21 beneath the bars 26 and between the scraper bars 27 and over the roller 22. It will be understood that the bars or scrapers 27 are so positioned with respect to each other in order to impart a squeezing or scraping action to the material as it passes between the same, in order that excess compound may be drained or removed from the material and fall back into the tank 23. By the above means it will be seen that the material which is passing beneath the bars 26, on the gate 25, will be caused to pass through the chemical compounds or solution 24 in the tank 23. I have mounted the shaft 28 at a suitable point on the frame 1, which is connected by toggle levers 29 with the gate 25 and I provide a handle 30 for rotating said shaft 28 in order to actuate the levers 29 in order to raise and lower the gate 25, should the same be necessary. In order to feed the material to the table 10 and fold the same properly in layers thereupon, in a fiat condition after having been treated with the solution 24, I provide the two rolls 31 and 32, said rolls being carried upon the shafts 33 and 34, which are carried upon or supported by the sliding guide members 35 and 36 which are movably mounted and guided by a suitable portion of the frame 1, in the present instance, upon the uprights 37 and it will be understood that the said guide members 35 and 36 are suitably mounted upon the uprights 37 in order that the rolls 31 and 32 will contact with the upper surface of the table 10 when the same is empty and that the said rolls 31 and 32 and shafts 33 and 34, together with the guide members 35 and 36 and other parts of the feeding mechanism, will be raised as the material is fed to the table 10, so that the rolls 31 and 32 will always engage with the material to feed the same to the table.

In order to rotate the mile 31 and 32 at the proper time and in the proper direction, depending upon the direction of movement of the support or table 10, I have loosely mounted upon the shafts 33 and 34 the gears 38 and 39, said gear 38 having pins 40 and 41 thereon at suitable points, while the gear 39 is provided with pins 42 and 43 at suitable points thereon. Meshing with said gears 38 and 39 is a gear 44 which is connected with a shaft 45 in any suitable manner, in the present instance by a slot or keyway 46 which is of suitable length in the shaft 45, as will be apparent from Fig. 1, in order to provide or permit of the up and down movement of the gear 44, which is provided with a suitable feather or key seated in said slot 46, while retaining the same in engagement with said shaft 45. The gear 44 is journaled between two ears 47 carried by one of the guide members, in the present instance, guide member 35, in order that said gear may be raised and lowered with the rest of the feeding mechanism. The shaft 45 is provided with a beveled gear 48 which is in mesh with a bev eled gear 49 carried by the power shaft 2, whereby reverse rotative movement will be imparted to the shaft 45, depending upon the movement of the power shaft 2, so that the gear 44 will be rotated first in one direct-ion and then in the other at the proper time, causing a reverse rotation to the gears 38 and 39. Suitably mounted on the shafts 33 and 34 and connected therewith are collars 50, one of which is provided with a pin 51 adapted for engagement by either of the pins 40 or 41 on the gear 38 and the other collar is provided with a pin 52 adapted for engagement by either of the pins 42 or 43 carried on the gear 39, it being understood that by these means I provide for a certain amount of lost motion, since as the gear 44 is rotated in one direction, depending upon the movement of the table 10, the gears 38 and 39 are rotated until one or the other of the pins 40 and 41 or the pins 42 and 43 contact with either of the pins 51 and 52, respectively, in order that move ment will be imparted to the shafts 33 and 34 and so to the rolls 31 and 32.

53 designates rods or bars, one of each of which is suitably supported adjacent each of the rolls 31 and 32 and in the present instance the bars 53 are carried by the supports or arms 54 which are provided with weights or weighted port-ions 55 which are adapted to hold the bars 53 and return the same to their normal position, as seen in Fig. 5 and in position above the roll 32, as seen in Figs. 1 and 2, said arms being freely supported upon the shafts 33 and 34, respectively. Intermediate the rolls and the supports, that is the arms 54, for the rods 53, I provide means which is adapted at the proper time to engage with the supports 54 in order to throw down the rods 53 or move the same into the position seen with respect to the rod 53, which is adjacent the roll 31 in Fig. 1. In the present instance, I have provided each of the rolls with pins 56, which are adapted to engage, after the rolls have moved a certain distance, or for example made one revolution, with a collar 57 which is also provided with a pin and said collar is thereby rotated until the pin thereon engages with a second collar 58, which is thus brought into rotation and which latter collar will finally engage with a pin 59 carried on the supports for the rod 53 for rotating the same and will so lower the proper rod 53 to cause the same to engage with the material at the end of the stroke or movement of the table 10. This will remove the material 20 from the roll 31 or 32, whichever it has been in engagement with and will cause a portion thereof to extend beyond the table or support 10 and so provide a slack in the material, which slack will be taken up and the material properly presented to be folded upon the table 10. In order to provide for the take-up of the slack, I have provided, in the present instance, two gripping members 60 and 61 which are suitably mounted in order to be rotated to grip the material and as here shown the members are mounted upon the disks 62, which are carried by a shaft 63 suitably journaled in the frame of the machine, in the present instance, in suitable journals on the uprights 37 The normal position of these gripping bars 60 and 61, is that seen in Fig. 1, with the material 20 passing freely therebetween. Mounted on the shaft 63 is a sprocket 64, around which passes a chain 65, which also passes around a sprocket 66, in order to provide for the proper rotation of the shaft 63 so as to reverse the position of the gripping bars and cause the same to engage the material 20, as in the position seen in Fig. 2. Connected with the sprocket 66 is a crank arm 67 which is engaged at the proper time by one of the pivoted latches 68, one of which is carried adjacent each end of the table 10 in order that as the table moves forwardly the crank 67 will be engaged by one of the latches 68 and will move up upon the same, thus imparting a suitable revolution to the sprocket 66, which will so actuate the chain 65 as to rotate the sprocket 64 and cause the gripping bars 60 and 61 to grip the material therebetween, pulling up the slack, and will place the material in position to be properly received upon the table at each reverse movement thereof, the relative movement of the material 20 being readily apparent from an examination of Figs. 1 and 2. After the crank has passed the latch 68 it will fall or be immediately lowered by any suitable means, in the present instance, by reason of the weight 69 carried by the sprocket 66, which will impart suitable movement to the chain 65 to rotate the gage the guide members 35 and 36 as they move upwardly and presenting a support ing surface thereto. In the present instance I have provided the movable members movably supported by the frame 1 of the machine, the upper face of which is inclined as at 71, to engage with an inclined lower face 72 of the guide members 35 and 36, said movable supporting members 70 having a rack 73 thereon which engages with a gear 74 carried on a shaft 75, which latter is provided with a weight 76 so connected with said shaft that when there is no pressure on the members 70, that is to say, as the guide members 35 and 36 are moved upwardly, the weight will cause a rotation of the shaft 75 which will actuate the gear 74 to move the supporting members 70 inwardly in order to cause the inclined upper face 71 to engage and remain in engagement with the suitable face on the guide members, 35 and 36. After the guide members have been elevated to their topmost position I have provided means for removing the supporting members 70 from beneath said guide members 35 and 36 and in the present instance I have shown a handle 77 for this purpose. In some instances it may be of advantage to provide a heating medium to the roller 21 and in the drawings I have shown a pipe 78 which is adapted to lead to a suitable source of heat supply and which communicates with the interior of the roller 21 and I may also desire to heat the material of the rolls 31 and 32 and I have shown pipe 79 for this purpose.

If desired, I may employ a means for supplying a suitable amount of heat adjacent the table or support 10 and in Fig. 5, I have shown a plurality of steam pipes 80 situated. beneath the table for this purpose, it being understood that the same are suitably connected wth a heat supply. I have shown the latches 68 adjustably supported 011 the table 10 and I can provide for the proper movement by making the number of teeth on the small sprocket 1 in suitable relation to the number of teeth on the large sprocket 66, which will impart a suflicient throw to the chain 65 to impart a suitable amount of revolution to the sprocket 64.

The operation of the device is as follows: The chemical compounds or solution to which the material is to be treated is placed in a tank 23 and the material 20 upon the roll 19 having been placed upon the yoke or supports 18 is fed over roller 21 beneath bars 26 and between the scraper 27 and so over the roller 22 down between the gripping bars 60 and 61 and into position to be engaged by one or the other of the rolls 31 and 32. Motion is imparted to the shaft 2 in order to impart movement to the table 10 and at the same time to the gear 1% in order to rotate both the rolls 31 and 32 in the proper direction. The end of the material, it will be understood, is so located, by hand at the beginning that, as stated it is in position to be engaged by the proper roll 31 or 32. As the table 10 advances, the end of the material is situated between the table and one of the rolls, which latter imparts sufhcient pressure which together with the chemicals in the material, will tend to hold the material upon the table while the c0I1- tinned forward movement of the table and the rotation of the proper roll will feed down the material from the roll 19, through the tank 23. WVhen the movement of the table is reversed the other roll will feed the material to the table while the chemicals will cause the layers of material to adhere together. In this way the material is fed down from the tank 23 and is caused to be laid in layers flat upon the table 10, as seen in Fig. 1. WVhen the table is in this position it will be understood that the same has just completed a stroke or travel in one clirection and is in a position ready to be started upon its return movement, that is, in the direction indicated by the arrow in said Fig. 1, it being understood that the pin 12 on the table 10, shown in Fig. 6, has engaged with the elbow lever 14 in order to shift belts 6 and 7 in the proper position for this return movement. The shaft 2 will then be rotated in order to impart suitable movement to the gear 8 and through the rack 9 to move the table 10 in the direction indicated by the arrow.- At the same time the gear 49 rotates gear 48 and thus the shaft 45 in order to rotate the gear 44 and thus the gears 38 and 39. By this movement the pin 41 is moved from its position, seen in Fig. 1, to cause the same to engage the right-hand side of the pin 51 while the pin 43 carried by the gear 39 will move around to engage with the right-hand side of the pin 52, immediately upon which motion will be imparted by means of these pins to the shafts 33 and 3 1 andas the gears are rotated, motion in a reverse direction is imparted to the shafts 33 and 3 1. It will be understood that the lost motion with respect to the rolls 31 and 32 as the table 10 begins a fresh stroke, is provided in order to allow the rolls 31 and 32 to remain stationary until the material 20 is substantially under the center of the roll about to be engaged and it is at this time that the pin 43 on the gear 39 will strike the right-hand side (in the position seen in the figures) of the pin 52, causing the collar and shaft 34 and the roll 32 to revolve, moving in the same direction as the table 10. The same movement or operation takes place on the opposite side when the table 10 reverses its movement in the opposite direction. If the rolls 31 and 32 should commence to turn as soon as the table reverses its movement, the material, being adhesive, would cling to the surface of the rolls and would be pulled and stretched causing an uneven fold of the material 20 upon the table 10. As the shaft 33 is rotated thepin 59 on the support 54, will be released from its engagement with the collar 58, whereupon the weight on the support will elevate the rod 53, removing it from engagement with the material 20, that is, from its position seen in Fig. 1. At the same time the forward movement of the table 10 causes the latch 68 at that end of the table to engage with the crank 67 and so will rotate the sprocket 66 and through the medium of the chain 65 will rotate the sprocket 64, which will impart a suitable amount of revolution to the disks 62, causing the bars 60 and 61 to grip the material, elevating the same in order to take up the slack, occasioned by the engagement of the rod 53 with the material 20 and will move the material over adjacent the roll 32, the bars being in the position seen in Fig. 2. As soon as the crank 67 passes the latch 68, the said crank will fall and the chain will be actuated by the weight 69, so that the bars 60 and 61 will be caused to return to the position seen in Fig. 1, releasing the material and causing the same to be engaged by the roll 32 which is rotating in the proper direction, to press the same down upon the top of the layer of material which has already been fed to the table 10. In the meantime, as the roll 32 rotates the pin 56 carried thereby will, say after one revolution of the roll, engage with the collar 57, which will thus be carried around'with the roll 32, say until another revolution has been completed, when it engages with the next collar 58 which will thus be carried after another revolution of the roll 32, at which time the pin 59 will be engaged and will cause the bar 53 of the roll 32 to be immediately lowered, engaging with the material 20, removing the same from engagement with the said roll 32 and pressing the same downwardly int-o a like position as that seen in Fig. 1 only upon the opposite end of the table, at which time the pin 13 engages the bell crank lever 14, shifting the belts causing the table to move in the other direction when a like operation of the parts takes place.

It will be understood that as the material is fed to the table and piled up thereon, that the rolls 31 and 32 and the operating parts connected thereto will be automatically raised and be in position to always move upon the top surface of the layers 011 the table and as the guide members 35 and 36 are elevated it will be understood that the movable supporting members 70 will be automatically forced inward in order to act as a suitable support for the guide members 35 and 36 and prevent any undue strain thereupon.

As previously stated, it will be understood that the scraping member 27 removes the excess compound or solution from the material 20 to be treated and that the gutter or groove in the table 10 will receive any excess compound from the material and the same can be collected and returned to the tank 23 for reuse.

From the above it will be seen that I have provided means for automatically feeding the treated material to a reciprocating support in order that the same will be fed flat and will be pressed upon the table in a flat condition in layers and I have provided means for taking up the slack in such a manner that the material will always be fed fiat without wasting of the same and in an even condition in order that substantially the entire product resulting from the use of this machine will be practical and capable of use.
