To all whom it may concern.-

Be it known that I, Inn J. Wnrxnnno, a citizen of the United States, anda resident of Chicago, county of; Cook, and tate of Illinois, have invented certain new and useiul lmprovements in Processes for Forming and stutling Compartment-Mattresses, of which the following is a'full, clea'rpandv exact description.

The invention relates to processes for forming and stu'fiing compartment mattresses and-eonsits in the ieatures of improvement hereinafter set forth and more.

particularly pointed out in--the appended claims. i

In the drawings which illustrate a ma chine for carrying out the improved process, Figure l is a plan view illustrating the manher of filling the compartment mattress and in which a portion of the mattress is broken away. Fig. 2 is a cross-section on the line 2-2 of Fig. 1. Fig/8 is a partial plan View of'the machine showing the sec compartment mattress.

'tional carrier: in retracted position. Fig. i is a perspectire view partly 1n section of a In iorming an ordinary mattress, the tickmg of cotton fiber or the like, and the filling material is then placed-under compression and is held in place by tufting the mat tress, i. 6., by connecting the opposite side Walls of the ticking by tufting stitches In a compartment or tuftless mattress, the 0pposite side Walls of the ticking are connected along parallel lines-to form a series of long, narrow compartments extending be-f tween the opposite side edges of the mattress and such compartments are subsequently stufied or filled, and in such constructions, the filling material is held under compression and against displacement within the narrow compartments. 7 Inasmuch asthe' mattress is not tufted, after it is filled, the material must be inserted within the narrow compartments under considerable pressure, so

the same. Heretofhre such compartment mattresses have beciii stufied by filling one pm-ting uprights 3. The horizontal andlonpresent invention,

is filled with material, such as layers vember 10, 1911, SerialNo. 661.410. as to snugly and compactly fill 7 puckered over .a row of spouts which are spaced apart'to receive the portions of the ticking which separate the eompartments bet veen them, and the charge of filling material is compressed and is deposited within the compartments by means of a sectional carrier which 1s adapted to be projected through the row of spouts.

In the drawings, Fig. *1 illustrates one form of coin 'iartment mattress in which theopposite side walls "1. are connected togetherat the edges of the mattress by edge walls 6, and between the edge Walls by .a series of partition walls 0, these partsbeing formed of suitable fabric. The connected partition walls serye the place of the ordinary tufting stitches tohold the filling material (Z under pressure and against displacement. But, of course, the partition'walls cannot be placed in position after the mattress is filled, but must be sewed to the side Walls along the lines 6 before the filling material is placed in the ticking. Preferably, the partitions c and the compartments extend transversely of the mattress between the side edges thereof andv the ticking is firstconr pletcd, except that the ends of thecompartincnts are left open at one of the side edges. The ticking is then preferably puckered. over a row of spouts which are spaced apart to admit the pa'rtitionso between them. The

divided into sections Within a suitable sec-- tional carrier and the latter is then advanced through the spouts andinto;the compartments of the tick to simultanebusly de posit all of the com-pressedsectionsjofthe I charge Withinthe same. a

By preference,

the sectional carrier is-mechemically operated. -The drawings illustrate a machine which is set forth and claimed in an application filed by me No- The body of this machine is mounted on a frame comprising side bars 1 connected by cross bars 2 and mounted 'upon suitable supgitudinal crossbars l and 2 support a floor or bed 1 and vertical side Walls 5, the latter beingfixed to posts (3 that extend upwardly from the horizontal side bars '1. The bet vided with flaring inner ends.

and side walls 5v form-a box-like body for receiving a-charge of filling material sufiicient to com )letely fill the mattress.-

A horizon al series or row of spouts are arranged at one end of the box-like body.

These spouts are preferably rectangular in section and have top and'bottom walls 7 and- 8 and opposite vertical sidewalls 9. The. spouts are spaced apart from one another, as,

" to the posts 6 at the adjacent end of the ma chine frame. The spouts are also preferably braced and held in position by a bar 11 which extends between the. end posts 6 and which extends over and is secured to the inner portions of the topwall 7 of the row of spouts.-

The bed plate Fl of the boxdike body is preferably provided with a. sheathing 12 of .sheet metal, and this sheathing is preferablyextended through the spouts'and over the bottom walls 8 thereof, as shown in Fig. 2. 5

Thespouts are of such size and are so spaced apart that the compartment ticking, ,when puckered overthe same. fits snugly thereon with the partition walls a between the spouts. The inner open endportion of theticking is preferably clamped to the spouts by a'pair of bars 13 which extend transversely above and below the spouts and "are connected by a series of bolts 14 arranged between the spoutsand'having thumb nuts 15 on their upper ends.

The sectional carrier comprises a sliding cross-head or bar 16 which is mounted upon the floor or bed 4 between the side walls 5. Upper and lower sets of thin flexible presser boards are connected' to the sliding crosshead or bar 16. The lower presser boards 17 are fixed to the bar 16 and the upper presser boards 18 are connected thereto by hinges 19. The upper portions are arranged in line with the lower boards, so that the carrier is divided to correspondwith the transverse row of spouts and to the compartments of the ticking. When the carrier is advanced, onepair-:01 boards is adapted to pass throughcach of the spouts, as indicated in Figs. 1 and 2.

The sectional carrier is -meehanical1y driven hyconnecting the cross bar 16 to a pair of drive chains. In. the form shown. these chains 20 extend over sprocket wheels 21 on shafts 22 at opposite ends of the machine frame. The'upper portions of the chains pass through slots 23 formed in the bed 4 and are connected to the cross-head 16 realises by bolts 24. In the form'shown, the shaft 22 at the front" end of the machine is provided with a large s rocket 25 which may l e driven in opposite directions from any suit' 'able source of ower. Whenthe sectional. as

carrier is comp etely withdrawn from. the spouts, the upper sets of prcsser boards 25-. can be raised and the entire charge of fillin material is plac'md within the box-like bod;-- of the machine upon the lower boards 12".

--Theupper boards are then lowered to coin .formed in brackets 28 fixed to and project in upwardly from the side walls 5. Prefer ab y, also, an additional pressure roller 29 as arranged adjacent the inlet ends of the spouts.

The charge of material isdivided into sec time either before or as it is advanced'inti" the ticking. In the machine illustrated, a my series of circular knives- 30 are mounted upon a cross shaft .31 that is journal'ed at it end in suitable brackets rising from the side bars 1 of the machine frame. These knives are ar'rangedin line with the v shapcd the at fiectors 10' between the inner ends of the. spouts and the loweredges of the knives ex tend through slots 32 in' the machine. first erably, also, as shown, the pressure roller is provided with notches 33 kc clear th edges of the knives. The shaft 31 is rcvided at one end with a pulley 34 on w icl: passes a belt 35. By this means the knives are continuously rotated during the opera tion of the machine. p

In carrying out the improved process, the compartment ticking is first completely formed. as described. except that the'com partments are left open a'lont', orient the side edges thereof. The ticking is then drawn overand puckered upon the transiuuei. row of'spouts with the partitions'o between 1 the spouts. The pressure rollers 25 are then removed an'dthe upper boards 18 of the sectional carrier, which has previously been i s withdrawn. are raised and the charge of material sufficient to stuff the entire mattress placed within the box-like body of the ma chine. he upper-presser boards are their. lowered lo compress the charge and the rollers 26 are replaced into position to hold the charge under compression, and the sectional carrier is then advanced tomove the presser boards through'the spouts and into the courpartments of the ticking. The charge is di-' vided into sections, either by therotary cutters 30 as it is advanced or, before it is advanced. by aid of the longitudinal partition hoards arranged within the box-like body of the.maohinc frame. As the sections of the teem throu h walls l "of the charge. Furthermore, the 'flarin deflectors atrthe inner ends of the side we ls-of the spouts serve to separate and compress the sections of: the charge.in lateral direcllfrtion.v Preferably,however, the pressure is relieved to some extent upon the sections of the charge as they pass from the spouts? As e the; sections of i the charge make their exit from the"s puts, they will expand laterally,

since they are confined against lateral; exl pension only by the sidewalls of the'spouts.

Furthermore, as the presser boards refthin and flexible-the expansive-tendency of the compressed filling material willspring the free ends of the boards apart, as indicatedin Fig. 2 of the drawings andthus', in a, measure; permit the charge to expand verti- ,"celly. This expansion of the charge sections I cannot .ihtehfre \vith'the proper filling of, .25 thecompartments. since by pucke'ring'the tick upon the spouts; the charges are deposited inthe extreme inner ends-of their 'com-- i artments as they emerge from the spouts;

his expansion otthe charge sections, as

80 they are deposited within the compartments of the ticking,"is advantageohs, since .itis necessary to relieve the pressure on the charge before theeseetional carrier is withdrawn.

- pletely inserted within thecompartments-of the ticking. the filling material will have'exp a nded along its side edges sufiiciently to engage the partition of the ticking with 40 sufficient friction to prevent the charge sec: tions being 'withdrawn with the clamping boards, this action heingassisted by the springing apart of the clamping'boards at 1 their free ends thereby not only relieving. the pressure to permit the "withdrawal" of the carrier whileflth e charge is' frictionally v sustained in place, but permittingthe simulv taneous withdrawal of I all portions of the carrier. This avoids complichtion of-mech- 6'0 anism which Would-be reqir'lred -if it was. necessary-to withdraw the carrier; portion- -carrier and of the charge are advanced the spouts, the; upper and lower and-8 of-the latter engage the upper.
