VHITE, a tained in the material undergoing comprescitizen of the United States,residingat Waco, sion may pass through said perforations and in the county of McLennan and State of Texas, out through the interior of the rollers, so as 55 5 have invented certain new and useful Imnot to interfere with the compressing action. provements in Mattress-Stufling Machines; The pass or space between the rollers is and I do hereby declare the following to be a designed to be varied according to the thickfull, clear, and exact description of the invenness of the tick to be filled.

The tick is roo 5o consists of two hollow rollersAA,Which may adapted to be drawn over the tick-holder, be corrugated and provided with perforations crimped together, as shown in Fig. l, and as it is fed with the stuffing material it is graduw ally pushed back from the tick-holder, as shown in Fig. il, and out upon a supportingtable G. The extreme lower forward end of the tick extends beneath the cross-piece or scraper d3, which therefore serves to guide the material into the tick.

lVhen the tick is to be stu ffed with unbaled or loose material, said material may conveniently be inserted within a suitable box ll, Fig. i), having in its bottom an endless conveyor-belt 7i, which passes over idler-rollers m ml m2 and about the roller A', from which it derives its power.

The conveyor, it will be noted, extends entirely through the pass of the rollers A A and beyond the mouth of the tick to the end of the table G, thereby absolutely insuring the eilicient delivery of the material into the tick. The conveyor thus serves not only to feed the material to the compression-rolls, but also to convey the same after compression and feed it to the tick. This construction not only affords a more direct and positive feed than where the material is projected by the rolls only, but, in addition, it prevents the dropping of material between the exit side of the roller-pass and the end of the tick. This is a matter of importance, especially where loose material is employed for stuffing, as illustrated in Fig. Sl.

When it is desired to fill the tick from bales of cotton that have been wound in a rollerpress upon a core having projecting journals, I locate said journals preferably in elongated bearings n, formed in supports N, located at opposite sides of the conveyor-belt i, Figs. land i2. The bale r in this arrangement rests directly upon theconveyer. As the conveyer moves, therefore, the bale is simultaneously unwound and the unwound layer carried forward toward the compressor. This forwardly-moving layer serves as the unwinding and forwarding` conveyor of the bale r in advance of it, and so on, the bales r2, I1"), tbc., being nnwound and their layers carried forward in like manner to the coinpressor by the moving layers beneath them.

For the higher grade of mattresses stuffed in accordance with my invention I preferably use cotton as the stuffing material, but in some instances, for purposes of economy and where a cheaper grade of mattress is to be produced, I may employ, in conjunction with the lower and upper layers of cotton, an intermediate layer or layers of some cheaper material, such as hay, excelsior, or the like.

The layers of stuiiing material as they approaeh the compressor enter the ilaring mouth of the condenser and are drawn upward by the rotating compressing-rollers, in conjunction with the conveyer-belaand in the compressed condition are fed upward into the open mouth of the tiek, which has been stretched upon the tick-holder in a crimped condition. As the material enters the tick .it gradually pushes the tick'from the tiekholder, filling it regularly and evenly with a compact filling of the stul'ling material. IVhen the tick is completely filled, the moving body of stuffing material has entirely pushed the tick in its filled condition off the tick-holder and upon the receiving-table. The machinery is then stopped by the operator, and it now becomes necessary to separate that portion of the body of stuffing material that has entered the tick from the remaining portion. For this purpose I make use of what I will designate as a dividen This divider, in the form shown 'in the drawings, consists of two sets of fingers t t', depending from cross-bars o n", which cross-bars are provided with supporting-arms w w. The arms uf' a-re connected to a rock-shaft to2, and the arms w are sustained in guides or bars wi, proj ccting upwardly from the arms to', so that the entire divider may be swung upwardly into the position indicated in Fig. i and sustained in that position when out of use by means of a chain e', engaging with a hook e" upon themachineframc- 'lransverscly of the arms uf' is journaled a shaft having pinions a, which engage with racks upon the under side of the arms fw, and on the outer end of the shaft z2 is a hand-wheel L" for rotating the shaft and its pinions.

'When the tick has been filled, as hereinbefore described, the divider is brought down into the position indicated in Fig. G and the teeth if t enter the stuffing niiaterial, as indicated in Fig. 4:. The operator thereupon re volves the shaft ,z2 and its pinions by means of the handavheel ,214, and consequently the teeth t are caused to move away from the teeth t', thereby pulling the body of stufiing material apart and separating the portion that is within the tick from the remaining portion. The iilled tick may thereupon be removed and another tick may then be drawn over the tick-holder for a second operation.

In feeding loose material through the condenser, under pressure, it will sometimes occur that a greater quantity of material is for a time at one side of the box, which would tend to tilt the cylinder A at one end, thereby straining the machinery and causing it to work with more friction and greater dii'iiculty. To obviate this diiiculty, I give a positive motion, alike at both ends,to the movable cylinder A. This is eil'ected by mounting a shaft k2 in the frame (l, said shaft being provided with pinions 7.5,iixed thereon and engaging with racks 7u upon opposite sides of the yoke B, so that one end of the movable cylinder will be at the same elevation as the other whatever difference there may be momentarily in the distribution of the material fed between the rolleipass.
