.To all whom it may concern:

' Be it known that I, JOSEPH W. SoHLoss, a citizen of the United States, residing at the city of New York, in the borough of Manhattan and State of New York, have invented certain new and usefulImprovements in Featherbone-Making Apparatus, of which the following is a full, clear, and exact description. 7

My invention relates to the manufacture of featherbone, and particularly to appara-' tus for completing the manufacture after the quills have been bundled together into a strip and wound in the usual manner. As is well known, the treatment of the strip in completing the manufacture entails three operations, first the sizing or subjecting the strip to a bath in a glutinous fluid, second, the drying of the sized strip, and finally, the rolling and compressing of the dried strip into its final form.

A general object of my invention is to provide an apparatus for this. purpose which will be simpler and more compact than those in general use, and which will be more. reliable in its operation. In the form heretofore used the apparatus has a sizing tank through which the strip is guided in a generally horizontal direction,

and a heated drying box having a slit in one end through which the sized strip enters after the surplus glue is removed, and having two power driven rollers over which the strip passes back and forth horizontally until dried, and a rolling machine outside the box through which the dried strip passes after it comes from the box. L machine is commonly provided with'heated The rolling rollers between which the strip passes and is heated asfit is compressed.

The passage of the strip through the air after it emerges from the drying box, when it is momentarily more or less cooled, and then the sudden subjection of it to therelatively great heat of the rolling machine, frequently deleteriously affects the strip, ren-'v dering it brittle, and an object ofmy invention is to obviate this disadvantage.

I have found that a superior product can be obtained if the strip is rolled while still at the temperature of the drying box before it is permitted to undergo any change in temperature, and I have further found that if this is done the heating may be dispensed with during the rolling operation. In accordance with my invention, therefore, I

place the rollers of the rolling device inside the drying box in position, 'to receive the dr ed strip as it comes off the'drum, and the driv ng means for the rollers are preferably outsldethe box and connected to the driving means for the drum so that the drum and rollers are driven at the same peripheral speed. In addition to rendering the device more compact and dispensing with heatmg means for the rolling machine, this 'construction has the advantage of producing a more unlform and resil ent article.

Ishall now describe the embodimentsof my'invention illustrated in the accompanying drawings, and shall thereafter point-out my invention in claims.

Figure 1 is a side elevation of a complete apparatus embodying my invention. "Fig. 2 1s afront elevation of the same with the reel removed and a portion of the frontof the drying box broken away. Fig.3 is a vertical sectional elevation, the section through the drying box being'taken on line of Fig. 2, and the section through the sizing tank being taken on line 3--3 of Fig. 2." i L Th'esizingtank comprises anopen receptacle 1. in which the sizing fluid is contained, the flanged ends of which rest upon a tank 2 which contains heatedwater.. The water is poured in through a stand pipe 3 which communicates with a pipe 4 entering the tank,

the height of the water in the tank being indicated by its. height in'the stand pipe 3. In order to heat the watenin the tank 2, two perforated gas pipes ,5 are provided un .derneath the tank which connect with the common pipeG communicating through pipe 7 with the gasmain 8, suitable cocks being provided 1n the pipes 5 to control the flow of gas. A door 2 affords access "to the nclosed gas pipes 5 underneaththe tank 2 .A frame 9 rests. upon the sidesof'thereceptacle 1, being secured thereto by thumbscrews 10, and has three guide-rollers '11 disposed in thesi'zing fluid, underwhich the strip 12 passes and is thereby guided through the sizing bath.

In order to remove any surplus glue from the material after passing through the bath,

the strip passes through 'a-suitable device.

such as a wringer, disposed [on the; sizing tank and. in the formshown having two a rubber rollers 13, the lower roller being mounted 1n stationary bearings and the upper roller being mounted in, bearing After passing through the wringer, the

sized strip enters the drying box 15 through a slit not shown in its front wall near the lower end at its right side. The drying box is what 1 term an upright box, being considerably elongated and standing on end with its longest sides vertical, and is located adjacent the sizing tank. Two horizontal arallel drums extending substantially the full width of the drying box are journaled in bearings on the sides of the drying box, one above the other, the lower drum 16 being disposed near the bottom, and the upper drum. 1'? being disposed near the top of the drying box. The lower drum 16 is power driven being provided on the left end of its shaft outside the drying box with a pulley 18 which may be driven by a belt or in any other suitable way. The upper drum 1'? may also be power driven but generally this is unnecessary.

The sized strip after entering the drying box is passed successively and continuously around the two drums, as shown, two suitable guidemembers 19 being provided, one near "each drum, which are attached at their ends to the sides of the drying box and have a plurality of fingers extending in the path of the strip and properly spacing the several I turns.

In order to remove'any glue from the drum 16 which may have been transferred to its surface from the freshly sized strip, a scraper 20 is provided which extends the length of the drum 16 and rests upon its periphery at such an angle as to scrape off the glue; This scraper 20 is attached to a transverse rock-shaft 21 journaled in the sides of the drying box, and a weighted -lever-arm 22 is attached to the r0ck-shaft so that its weight serves to yieldingly hold the scraper 20 against the surface of the drum 16.

p In order to supply heat to the drying box to dry the strip of material as it is rotated over the drums, a stand pipe 23 is provided along the vertical side of the drying box opposite the side at which the freshly sized strip enters. inner side perforated, as shown in Fig. 3, and communicates at its lower end with a pipe 24 leading from a gas heater 25. Air is drawn into this heater by a fan26, and this air is heated by burning gas emer ing from a plurality of perforated pipes 2 at the bottom of the heater which communicate with the gas main 8, as shown in Fig. 2. It is apparent that the heated air will pass through the upwardly-inclined pipe 24 and into the stand pipe 23 and thence through This stand pipe 23 has its the perforations into the drying box, this natural circulation being assisted by the fan '26. It will be noted that the strip as it dries approaches the stand pipe 23 in its passage around the drums, and it is therefore subjected to increasing heat as it dries out and its thorough drying is thereby assured.

After the drying operation is completed and the strip comes 05 from the drum 16, J

passing through a slot provided for this purpose in the scraper 20, as shown in Fig. 3, it enters the rolling machine and is rolled and compressed before it passes out of the drying box, thereby finishing the article without subjecting it to any sudden changes in temperature. The rollers 28 and 29 of the rolling machine are mounted upon the inner ends of two parallel shafts 30 and 31 which extendhorizontally into the drying box in front of the lower drum 16 at the end from which the dried strip passes ed the drum, and these shafts bear in frames 32 and 33 outside of the drying box which are supported upon a bracket 3d on the side of the box. The lower shaft 31 is mounted in stationary bearings and the upper shaft 30 is mounted in vertically-adjustable bear- 'i-ng blocks, the vertical position of which is controlled by adjusting screws 35, suitable locking nuts 36 being provided to lock the screws in adjusted position. By these means the roller 28 may be made to approach its complementary roller, more or less, and the compression upon the dried strip be thereby adjusted.

The roller 28 has a circumferential tongue which fits into a complementarygroove in the periphery of the roller 29, and the dried strip as it comes off the drum 16 is passed through the groove in the roller 29 and is compressed andshaped. It is apparent that the tongue and groove may have either transversely flat or curved engaging surfaces, as is desired.

The rollers 28 and 29 are driven in opposite directions, by intermeshing pinions 37 on the shafts 30 and 31, the lower shaft 31 being driven from the drum 16 by a sprocket chain 38 which passes around a sprocket wheel 39 on the end of theshaft 31 and around a sprocket wheel 40 on the-end of the drum shaft. Thesprocket wheel- s 39 and 10 are so proportioned in size, that the rollers 28 and 29 are driven at the same rate, that is, at thesame peripheral speed as the drum 16, and the tension upon the strip as it passes through the rolling machine is therefore the same as it is when passing over the drums.

After passing through the rolling machine, the finished. strip emerges from the drying box through a slit 41 in front of the box, and from thence to a suitable reel 42 on which it is wound, the reel being driven by a belt 43 which passes around a pulley 44 on the shaft 30 and over a pulley 45 on the reel, the friction of the belt being such that it will slip as the size of the roll of featherbone increases on the reel, and will therefore at all times rotate the reel just fast enough to Wind up the finished strip.

The drying box is provided on its front with hinged doors 456 which meet at the middle and are provided with suitable locking means, and which extend from the top well down toward the bottom of the box, the lower part of the front being provided with a removable portion 47 secured in place by slide bolts, in the usual Way, thus the front of the drying box can be opened and access readily had to its interior.

It is obvious that various modifications may be made in the construction shown in the drawings and above particularly described, within the principle andscope of my invention. I

I claim p 1. Featherbone making apparatus comprising a drying box provided With a source of heat, a plurality of drums rotatively mounted therein and arranged to receive and convey a continuous strip of sized material passed successively around them, a rolling device disposed within the drying box and arranged to receive the dried strip as it comes from the drums, and means for driving one of the said drums and the rolling device at the same rate.

2. Featherbone making apparatus comprising a drying box provided with a source of heat, a plurality of drums rotatively mounted therein and arranged to receive and convey a continuous strip of sized material passed successively around them, guide members adapted to properly guide the strip over the drums, a rolling device disposed within the drying box and arranged to receive the dried strip as it comes from the drums, and driving means for therolling device arranged outside the driving box.

In Witness whereof, I subscribe my signature, in the presence of two witnesses.
