12 Claims. (Cl. 91-8) a a cement coated surface of'suitable carpet material, such as a burlap covered base of rubber, while the carpet material is being vibrated so that the vibration will cause the fibers discharged from the distributor to be imbedded endwise in the cement to simulate the pile of.a conventional woven carpet.

Another object is to provide a distributor provided with means for breaking up balls, pills, or other objectionable formations of the fibers.

Another object is to provide a distributor wherein the means for breaking up the balls, pills, etc., of fibers is in the form uof cooperating sawtoothed blades carried by spaced horizontal shafts that rotate in opposite directions.

Another object is to provide a distributor wherein the saw-toothed blades may be adjusted relavis simple in construction, economical to manufacture, easy to install andefiicient in operation.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 1 is a side elevation of a machine for making carpet and having a distributor embodying our invention;

Figure 2 is an elevational view of the distributor;

Figure 3 is an end view of the distributor illustrated in Figure 2;

Figure 4 is an enlarged vertical sectional view through the lower portion oi the distributor illustrated in Figures 1 and 2;

Figure 51s a sectional view taken substantially on the line 55 of Figure 4.

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

- As shown in Figure 1, th 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 ll.

Cooperating belts l2 and I3 respectively are employed for withdrawing the carpet material ill from a roll l4, and other conveyor means including a belt I5 is employed for advancing the carpet material through the adhesive applying mechanism H and over suitable rotary beaters it which vibrate the material after the adhesive substance is applied to the upper surface thereof.

tary sieve (not shown) located between the adhesive applying mechanism II and the distributor A onto the adhesive coated carpet material as it is vibrated so that such fibers will be imbedded in the adhesive coating to form the cemented pilecarpet. If desired the fibers supplied to the distributor. A constituting the second point of application may be excess fibers from the sieve mentioned constituting the first point of application. Moreover, such excess fibers may be mixed with a certainpercentage of freshly cut fibers for the second application.

Preferably the distributor A has a'casing 20 that is relatively narrow and elongated in configuration so as to extend transversely over the advancing carpet material It on the belt l5, hingedly mounted deflector plates (not shown) for directing a portion of the cut fibers toward opposite endsof the casing 20, and rotary sawtoothed blades 22 for breaking up balls, pills or other formations of the cut fibers.

The casing 20 is provided at its upper end with an inlet 30 through which the cut fibers are adapted to pass from a collector or other suitable source of supply (not shown), and has an open lower end 3i through which the cut fibers are adapted to be discharged onto the adhesively coated carpet material It. 32 are windows in one side of the casing 20 through which the operator can inspect the mechanism within the casing, and 33 are removable panels which may be in the same or another side of the casing to afford access to the interior thereof.

Preferably the upper portion 34 of the casing is inverted V-shape in configuration, and the inlet 30 is at the apex of the V, while the lower portion 35 of said casing is substantially rectangular shape in configuration.

The saw-toothed blades 22 are in the lower I blades on adjacent shafts 62.

Preferably adjacent shafts 62 are rotated in opposite directions at relatively high speed by mechanism (not shown) so that the saw-toothed blades 22 carried thereby will break up the fibers, especially balls, pills, etc., thereof coming in contact therewith and will distribute the broken up or loose fibers downwardly so that they will be discharged from the lower open end of the casing 20 onto the adhesive coated carpet material In use, the fibers may be supplied to the inlet 30 of the casing 20 by any suitable means (not shown). Upon reaching the lower portion 35 of the casing the fibers aforesaid will engage the rotating saw-toothed blades 22 which will distribute the same downwardly through the lower open end of the casing onto the advancing adhesive coated carpet material Hi. If some of the fibers-have gathered into balls, pills or other objectionable formations, the saw-toothed blades 22 will effectively break up such balls, pills, etc., so that the separated fibers in substantially free or loose condition will be distributed downwardly through the open end of the casing onto the cement coated carpet material. Thus, all of the i fibers discharged from the lower end 3| of the casing will be free and loose and will be distributedwith substantial uniformity onto the carpet material.

What we claim as our invention is:

l. A distributor having a casing provided at the top thereof with an inlet and provided at the bottom thereof with an outlet, and means within saidcasing for breaking up balls, pills and other formations of cut fibers admitted to the inlet so that the fibers as individual elements will be diswithin. said casing for breaking up balls. pills and other formations of cut fibers admitted to the inlet so that the fibers as individual elements will be discharged through said outlet, including staggeredly arranged rotatable shafts, toothed blades carried by said shafts, and means for rotating said shafts in opposite directions.

4.
