UNITED LEWIS M. KELLOGG, OF LOS ANGELES, CALIFORNIA.

DRUM PRESS non FABRIGATED MATERIALS; v

' Application filed January l2, 1923. SerialrNo'. 610,396.

To all 107mm t m my concern Be itl known that I, LEWIS M. KELLOGG, a citizen of the United States, residing at Los Angeles, inthe county of Los Angeles and State of California, have invented newand useful Improvements in Drum Presses for Fabricated Materials, of which the following is a specification.

My invention relates to improvements in presses adapted to compress firmly fabricated materials which have been put together with glue or other binder and which require time and pressure for the glue or binder to set, the objects being to provide a press having capacity to continually receive and compress thefabricated 'material as it is dis? charged from a loom or other manufacturing machine; another object being to provide a press having a compressing means which glue or binder will not stick to and which can be .easily cleaned; still another object being to provide a rotating press having a compressing medium which clamps the fabri.

cated material between perfectly flat and unyielding surfaces; the device being adapted, more particularly, to `press thin ply wood or a wood fabric woven from thin ribbons of wood and glued in the lap of the warp and weft, with waterproof glue, whichrequires immediate and continued pressure.

With reference to the drawings- Fig. 1 is a side elevation of the entire device including a loom.

Fig. 2 is a top view of the device as shown 35 in elevation in Fig. 1, with the loom omitted.

The present invention comprises a compression drum l, having a shaft 2 rotatably mounted in bearings 3, 3 which are secured to a concrete foundation 4, and a reel drum 5 having a shaft 6 mounted in bearings 7, 7 secured toa concrete foundation 8.

The drum 1 is adapted to be rotated/by' a worm gear 9 rotatably mounted upon the shaft 2, there being a lclutch 10 slidably mounted upon the shaft 2 adapted to engage the hub of the gear 9 and through which the` foundation 4 and `support a frame 16, 16, which carries a beam 17 and a pressure roller 18.4 The roller 18 bears against the drum on one side andthe beam 17 carries a plurality of shoes 19, which bear against the drum on the opposite side, there being a retractile spring 2O disposedbetween each shoe and the beam. Upper and lower arms 21, 21 extend. from the shoes 19'and rest slidably upon the beam17. The roller 18 is carried in slidably mounted bearings, inthe frame 16, 'which are moved towards the drum by retractile springs as shown.

The drum 1 is adapted to bewound with spring steel or brass bands 22, the ends'of which are fixed to the drum, the bands pass-,l l I l ing under a rubbing block 23 and overa. guide roller 24. The guide roller 24 is priovided with thin metal discs 25 between each band which keep the bands separated and in proper alignment. l

The reel drum 5 is composed ofa plurality of narrow band wheels each of which isv rotatably carried upon the shaft 6. Arms 26, 26 are vpositively mounted upon the shaftfA and carry a bar 27 between the spokes of` the band wheels forming'the drum 5. Between the bar 27 and a spoke of eachl band wheel is a retractile spring 28 so. that a, movement `of the band wheels is caused by, or resisted by the springs 28 and bar 27.

Upon the shaft 6 two friction brake wheels 29, 29 are positively mounted. Brake levers 30, 30 and 31, 31 are pivoted at theirbottom 85 ends in the foundation 8, two of .which bear oppositelyV upon each of the brakewheels. Each pair of brake levers is pulled together at the top by bolts 32 and 32, there beingtension spring 33 and 33 upon the bolts as shown. i The ydrum 5 is rotated by a worm 41 ycarp ried upon a shaft 42 having a band pulley 43, the shaft being mounted inbearings 44, 44. The worm .41 meshes with a ,worm "wheel4 45 which is rotatably carried by the shaft 6, there being a clutch 46 adapted to slide upon the shaft 6 to engage the hub of the worm gear and thereby cause a rotation of the shaft. f

v The other ends of the bands 22 are fixed y one to each of the band wheels of the drum each band is fixed one to each of the band` wheels of the drum 5 and nearly the entire length of the bands is then wound there' upon. 'The other ends are then carried under theV rubbing block 23 and over the guide roller 24 and fixed to the drum 1 in proper alignment. v

A loom is positioned between the two drums as shown, the bands 22 passing under the loom. Briefly the loom comprises a frame 34 at one end of which is carried warp reels v`35, in the center holding frame guides 36 and a shuttle37. The warp is indicated by lines 38 and a weft 39 is shown in the shuttle, the weave being indicated by the numeral ,40 discharging into the windings of the compression drum.

In the operation of the device the brake levers v30, 30, and 31, 31 bear firmly enough to properly resist the rotation of the band wheels of the drum 5 and maintain the steel bands at a proper tension. The clutch 42 is released from the worm wheel 41 and the clutch 10 is engaged with the worm wheel 9 of the drum 1.

A power belt over the pulley 14 will then y rotate the drum 1 to wind up the bands from ofi" the drum 5. The fabricated material 40 is then fed to the drum 1 between the layers of the winding bands, the drum 1 being ro I tated just fast enough to take up the material as it isdischarged from the loom.

The shoes 19 and roller 18 which bear upon the drum 1 act to rub down the bands so that they present an even face alignment and aid in compressing the fabric and, while the V'bands are being rewound upon the reel drum,

to hold a tension on them so that the rewinding will proceed evenly.

After the required length of the fabric is wound upon the compression drum the fabric is then cut off and an extra turn or two of the bands is wound upon the drum toiinsure the last of the fabric being properly compressed. The drum is then left to Vstand the required length of time for the glue to set when it is unwound, the bands upon the reel drum and the sheet of compressed fabric upon a separate reel to dry or otherwise disposed of. This last operation `of unwinding the compression drum is effected by disengaging the clutch 10 of the drum 1 and engaging the clutch 46 of the drum 5 when, with a power belt over the yoflice on the other side of the bands.

pulley 43, the reel drum is wound up against the resistance of the roller and shoes 'on the drum l. For this operation the pressure of the levers 30, 30 and 31, 31 on the brake wheels 29, 29 may be relieved.`

The rubbing member pressing against the drum 1 acts to clean the bands on one side, in winding and rewinding, f any foreign particle which might come O the fabric and the rubbing block 23 may perform the same The bands may be greased slightly to prevent glue and the like from sticking to them.

rl`he shoes 19 of the drum l may be replaced with a roller should the rubbing element drag too strongly on the bands in the compression of some fabrics.

A single wide band is impractical to use in place of the plurality of narrow bands for it is pointed out that the press must be made wide enough to receive fabric of a width of from four to ten feet and such Va wide single sheet of metal would be hard to make up without buckling and developing uneven pressure in winding, hence for such a purpose the narrow bands must be adapted.

It is to be understood that the width and number of the bands used forms no part of my present invention and that many changes might be made in the invention as shown without departing from the spirit thereof as claimed.
