This invention relates generally to carpet mak ing machines for manufacturing carpet of the type disclosed in United "State's 1Patent No. 2,187,140, datedJanuarylfi, 1940, and constitutes a division of our applicationifiled October 28., v

One of the essential objects jof the invention is, to provide an improved distributor Iorfeeding cut fibers, such as cut ,hairand the like, onto a cement coated suriacev of suitable carpet material, such as a burlap covered base of rubber,.whil e the carpet material is being vibrated so that the vibration will cause the fibers dischargedfrom the distributor to, [befimbeddedl.endwise, in the cement to simulate th pile, 'otva conventional wovencarpetgiy 1 Another object is toprovide a distributor wherein fibers admitted to the'u ner portion thereof are adapted to be distributed substam tially uniformly to thel'ower portion thereof} Another object is to provide a distributor having anelongated casing. adaptedto extend transversely over advancing cement coatedcarpet material and having means withintheupper portion admitted thereto casing.

g H a Another object is toprovide a distributor wherein the directing means justihentioned. is adapted to be adjusted to various positions fonvarymgthe distribution of the fibers; and is capable 'bfl'being locked in any desired adjustedposition ,Another object is; to; prlovide i l-a distributor wherein the directing means,includesia'pluiiaiity toward opposite ends. of the of hingedly mounted deflector hates whammy accompanying drawings, wherein Figure 1 is a side elevationof a machine for making carpet and having a distributor embodying our invention; I

Figure 2is an elevational-view. J of the distributor; Figure. 3 is an end viewof the distributor illustrated in Figurfizk v -.-Figure *4 is a vertical sectional view through the-upper portion of the distributor illustrated .in Figures landZia of the casing for directing'portions of the fibers Figure 5 is a View partly in vertical section of the structure illustrated in Figure 4, and showing by dotted and full lines different positions of adjustment for the pivoted deflector plates.

Referring now to the drawings, Ais a distributor embodying our invention and constituting a part of a machine illustrated generally inFigure 1 for manufacturing carpet of the cemented pile type.

As shown in'Figure l, the'carpet material l0 such as burlap covered rubber, is advanced through the machine with the burlap side thereof uppermost so that the upper surface of the burlap may be coated or covered with an adhesive substance or cement as the material passes through an adhesive applying mechanism l l. Cooperating belts I2 and 13 respectively areemployed for withdrawing the carpet material H! from a roll I4 {and otherfconveyoi means including a belt I5 is employed for advancingthe carpet material "through the 'adhesive applying mechanism l l and over suitablej' rotary beater-s I6 which vibrate the material after the 'adhe sive substance is applied to'the upper'surfaee thereof.

Cut fiberssuch as cut'hair or the likef tre discharged from the distributor'A, and from a rotary sieve (not shown) located between the adhesive applying'mechanism H and the distributor A onto the adhesivec'oated carpet] material as it 'is vibrated so that such fibers will be imbedded in the adhesive coating to form the cemented pile carpet. If desired the-fibers supplied-to the dis- 'tributor A constituting the secondpoin't "of "application; may be excess fiberls'from the'sieve-mn tioned constituting the first 'point oi application.

Moreover, such excessffibers maybe mixed with a certain percentage of freshly cutv fibers'for the second application, g j I fl Preferably the distributor A has" a cas ngfifi tha'tfis relatively narrowfand elongated inconiigu'ration so as tofeirtend transversely o'verthe advancing carpet material jl0 "on the belt l5 hingedly mounted deflector plates'zl for directing a,v portion ofthe cut fibers' toward, oppos e ends of the casing 20:, and 'ijot'aryi'saw-toothed blades (not shown) for breakin 1 D balls, pills or other formations of 'the cut fibers. v The casing 20 is provided at its upper end with an inlet 30 through which the, cut fibers'j jare adapted to p assfroma collector or othersuitable I source ofsupplyinot shown), and hasan open lower end 3l through which the cutfibei sjare adaptedtto be discharged onto the adi i ejsii qly coated fcarpet .material are windows in. b s' 9 i i 'fl 'll'i mig w e t e roperator caninspect the mechanism within the I casing, and 33are removable panels which may be in the same or another side of'the casing to afford access to the interior thereof.

Preferablythe 'uppe portion:34 ;ofthe casing is inverted V-shape in.- configuration; and the .inlet3t is at the apex of the V, while the lower portion 35 of said casing is substantially ree tangular shape in configuration.

The deflector plates 2| are in I the "upp er E36? 7 tion 34 of the casing and are-adapted todirect Tithe inlet toward certain areas of the outlet, a

some of the fibers from the-inIet-EEG tow'ard oppoe site ends of the casing 28. Preferably thes'plates' 2| are hinged attheir upper ends upon horizontal pivot shafts 36 carried bydth e casing and are pivotally connected adjacenttheir, lower ends, a to links 31 that extend laterally from and are' pivoted to levers 38 and 39 respectively'lgeyed or otherwise non-rotatably mounted on shafts 4i!" and 4| journaledinbrackets 42 and 43 carried by the casing. Meshing pinions :44 and 45 are fixedto the shafts 4!! and 4!, and a-hand lever 45 is fixed to the shaft 49-. {Thus when the hand lever 46' is swung in thearc of a circle, the pinions 44 and 45; will cause the shafts 48.;and 4| to rotate in unison and therebyswingl the levers 38 and :39,, links- 31 and deflector plates ;2|;'simul taneously as indicated by full and dotted lines 7 in Figure 5. A plate 41 is rigidly secured to the bracket 42 beside the hand'lever45 and has an arcuate slot; 48 therein substantially concentric to-the axis of theshaft 40, while a bolt 49 extends through the slot-48 in the plate 41 and through thehand lever 45 and is engaged upon theeouter 5" side of. the latter by-a winged-nut 59. Hence thewinged nutfifl may be adjusted on ,the bolt 49 a to holdfthehand lever 45 in adjusted position,

In use, therfibers may be supplied tovthe inlet 30 0f thejcasing 20 by any suitable means (not shown) Portions of these fibers will be directed by the deflector platesZl toward opposite ends of the casing 20, disposed over opposite side edges 7 of theadvancing carpet material III, while other portions of the fibersrwill fall between the pivots '36 at the center of the-casing. The deflector plates" 2| may beswung to the desired inclined pair of shafts carried by the casing, meshing gears on said shafts, levers fixed to said shafts, Jinks connectingthe levers to said plates, an op- ;erating. lever fixed to one of said shafts, and

* lme'anszengag'eable with said operating lever to holdithe-levers, links and plates against move- I ment.

3;; 'distiifpdtdsiiavin a casing provided at the op'thereof withi a'n inlet and provided at the bottom thereof with an outlet,'and means within the casing for distributing toward opposite ends of position by;the hand lever 46 and then may be 5 held in suchadiusted position by, tightening the winged nut 50, Upon re'achingthe lower portion 1 35 of the'casing the fibers aforesaidwill engage the rotating saw-toothed. blades (not shown) which will distribute the same downwardly through the lower opengend of the casing onto theiadvancing adhesive eoatedmarpet material l0; Ifisome of the fibers have gathered; into balls, pills: or other objectionable formationsthe sawtoothed blades (not shown) -fwill effectively break up such balls, pills, etc.',.so thatrthe. sepal'aitedfibers in substantially free or loose condition will be distributed downwardly lthroughgthe open end of the casing onto thecementpoat'ed carpet material, ,Thus,] all of the fibers dis charged from the lower end13l of the casing will belfree and loose and will be distributed'with sub- 565 stantialuniformity ontov thejcarpet material What we claim as our invention is:
