METHOD OF AND APPARATUS Application filed Kay 22,.

My invention relates to a method of and ap aratus for producing mattresses.

n accordance with my method, I contemplate taking the linters from a linter gin and introducing the same to the screen drum of a condenser. Instead of obtaining the lintersfrom a linter gin that is ginning the cotton seed, I ma introduce into this gin previously baled lmters, and regin the same to aerate it, or may pass the baled linters through a willow or opener and pass this reginned or aerated liners to the condenser. I also contemplate reginning or aerating cotton and cotton waste, thereby using cotton fibre which has been reginned or aerated. The layer of cotton fibre or linters, thus ginned or reginned, or aerated, is removed from the condenser drum or screen and passed over a lapper which arranges the same in layers, in a stepped manner, upon a continuously traveling endless belt, producing a felt. The felt thus produced is built up to the proper thickness for a mattress and may be torn or cut at suitable points, producing a section of felt of the desired length for the mattress. This cut section of felt may now be suitably, com pressed and fed into the tick or casing of a' mattress, which is removed from the stufiing machine and transferred to the sewing machine. A new tick is at once placed uponthe stuiling machine. I also contemplate a somewhat simplified method, in whidh the fglt is first compressed and fed into the tick, and then torn, or cut when the tick is filled. By virtue of this method, I am enabled to handle the linters or cotton fibre, directly from the condenser, and supply the same into the tick, in a continuous and expeditious 40 manner.

In the accompanying drawings forming a part of this specification, and in which like numerals are em loyed to designate. like parts throughout t e same, Figure 1 is a plan view, partly diagrammatic, of apparatus embodying my invention, parts broken away,

Figure 5 is a similarview of a further 1 modified form of mattress making machine, Figure 6 is a side elevation of a further modified form of the invention, and,

Figure 7 is a side elevation of the combs. In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a cotton or linter gin or regin, preferably of the construction shown in my copendmg application for method of ro- 1 ducing felt from cotton and linter fibre, led February 15th, 1924, Serial No. 693,136. This gin is adapted to remove the linters from the cotton seed, and to aerate the same. Leading into the top of the linter gin casing 10 is a suction pipe 11,'leading to the easing of a condenser 12, within which is rotated the usual screen drum 13. The casing has communication with a suction fan or blower 14. The linters or'cotton fibre accumulates upon the upper surface of the screen drum 13, and is removed therefrom "by rollers 15, and the layer of linters or cotton fibre is then passed upon a lapping machine 16. This lapping machine embodies an endless conveyor passed over a frame 17, pivotally supported at 18, to swing in'a vertical plane. The movable end of the frame is pivoted to thecompanion frame 19, and this companion frame has its 0 posite end sup ported by wheels 20, whic travel upon a track 21. The usual means is employed to cause the lower/ end of the frame 19 to travel back and forth upon the-horizonta1 track 21, whereby the frame sections 19, at g their upper ends, reciprocate vertically; By this means, the layer of linters or cotton fibre is distributed in layers, in stepped relation, upon a continuously traveli endless belt 22. The construction of the apper 1 is generally that shown in the ordinary camel-back lapper, although other forms of lappers can be used. g

The endless belt 22 is preferably slightly inclined, and is adapted to dischargethe felt I produced thereon by the lapping operation, upon a gravity operated conveyor, which is inclined and embodies a plurality of idler The vity operated conveyor, Figure 3, may o be in the form of an 1 an 1nclined bottom 23f and sides 23 he felt slides down this inclined chute. Prior to the passage of the felt upon this gravity conveyor, the felt is preferably torn or cut into a desired length. This is accomplished by passing the felt between upper and

lower rollers

24 and 24; and 25 and 25'. The rollers 24 and 24' are not vertically movable and are driven at the same speed. The

rollers

25 and 25 are vertically movable, and rotate in the same direction as the rollers 24 and 24', but at a higher rate of speed. When the

rollers

25 and 25 are moved inwardly so that they engage with the cotton felt, they pull, tear or break the same at this point, producing the section 26, of the desired length to pass into the mattress casing. The gravity conveyor is convenient, inasmuch as it produces a slight intermittent feed of the felt section and the-mattress stuffing machine, .thus giving sufiicient time tick and to place another casing or tick thereon.

The gravity conveyor discharges upon an endless conveyor 27, included in a mattress stuflingma'chine. The endless conveyor 27 is preferably horizontally arranged, and above it is an inclined endless conveyor 28, the conveyors traveling in the direction of the arrows. The conveyors 27 a d 28 are therefore arranged in a Wedging r lation, tapering forwardly, toward the nozzle 29.

This nozzle is preferably slightly transversely tapered, increasing in width forwardly. The nozzle receives thereon the open end or side of the tick or casing, which is supported upon the rolling table 30 when filled. The section of felt thus passed between the

endless belts

27 and 28, is compressed, and fed through the nozzle 29 into the tick, and supported upon the table 30. The table is then rolled to the sewing machine, and the open end of the stuffed tick is sewed as it passes under the sewing machine, after which the table 30 is returned to the stuffing machine, to receive another tick filled with felt from the nozzle 29. The next out section of felt will then be fed to the stulfing machine and into the mattress ticking.

In Figure 4 I have shown a slight modification of the mattress stufiing machine. In this modification, the upper inclined endless belt 28 is dispensed with, and a coacting cylinder 28 substituted therefor. The felt is pressed between the cylinder 28 and the 55 endless belt 27 and is fed through the nozzle 29.

In Figure 5 I have shown a further modification of the stufiing machine. I The

endless belts

27 and 28 are dispensed with, and the rollers 23 of the gravity conveyor passed directly to cylinders 31, which serve to compress the felt and force it through the nozzle All other parts of the apparatus remain the same.

In Figure 6.1 have shown a further modito remove thepreviousl-y stuffed casing ormattress casing and sewing the same.

fication of the invention. The gravity conveyor, and the cutting of the felt before it passesthereon, is dispensed with. The endless belt 22, upon which the layers of linters or cotton is lapped, discharges through a passage between the belt 22 and a compression roller 31, which serves to compress the felt and force it through a nozzle 32, having the mattress casing thereon, which is later supported by the table 30, as it becomes filled with felt. Arranged near the discharge end of the nozzle 32 are upper and lower vertically

movable combs

33 and 34. These combs are normally arranged out of engagement with the mattress casing and above and below the discharge end of the nozzle. After, a suitable amount of felt is thus fed into the casing, the casing is removed from the nozzle, and thecombs 33 and 34 moved inwardly and penetrate thefelt. The upper con b may be employed to hold the felt against movement while the lower comb may be moved toward the table 30, thus tearing or breaking the felt.., The invention is in no sense restricted to this particular means of cutting, tearing. or breaking of the felt, as other means may be employed, such as rollers, blades or the like.

It isto be understood that the forms of my invention herewith shown and described, are to be taken as preferred embodiments of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to, without departing from the spirit of my invention, or the scope of the subjoined claims. v
