TO ALL PERSONS TO WHOM THESE PRESENTS SHALL COME:

Be it known that I, ENOGII WAITE, of Franklin City, in the county of Norfolk, and State of Massachusetts, have invented an improved Machine for Making Fibrous Bats for Iadding or for being Felted; and I do hereby declarethe same to be fully described in the following specification, and represented in the accompanying drawings, of which--A Figure 1 is a top view.

Figure 2, a longitudinal section; and

Figure 3, a transverse section of it.v

Figure 4 is a front end elevation, showing the endless apron and the machinery for actuating the striker, to be hereinafter described.. i

This machine is similar in many respects to others in use for the samel purpose, that is to say, it not only has two cai-ding engines placed at right angles to each other, but an endless apron to remove a bat from one of such machines. It also has a mechanism hy which a fibrous hat or series of such is taken from the other carding engine and laid on the longer bat transversely, the same being in order that the fibres of the two bats may cross one another at right angles or thereabouts.

The difliculty which has been experienced with the machines heretofore used for so making bats for being felted or otherwise employed, has been to operate the two carding engines and the endless apron at the right speeds to cause the transverse bats to be laid at the exact or proper periods of time, and without lapping upon one another upon the longitudinal bat. To overcome this diliicult3v and insure correct deposits of the transverse bats, I so combine the two sets of feed-rollers of the two bats, by mechanism as hereinafter described, that they nins't always move in unison, or with the requisite speeds for the correct deposit of the transverse bats on the longitudinal but, however the speed of the endless apron carrying the longitudinalbat may vary. I have also a new or improved mechanism for removing the transverse bats from the carding engine and depositing them upon the longitudinal bat. i

In the drawings, A and B represent portions of the frames of the two carding engines, which, when in use, are disposed at or about at a right angle to one another. C is the endless apron proceeding from the main carding engine, and destined to receive the bats discharged from its doffer. This endless apron is supported by and travels on two rollers, I) D', the journals ofthe latter roller being sustained by a frame, F, lbetween which and the main' frame A of the cnrding engine, and so as to extend4 over and across the endless apron, and from the frame B of the auxiliary carding engine, is another frame, G, constructed as shown in the drawings. The doifer of the auxiliary cai-ding engine is shown at II. In advance of it is a feeding-drum, I, surmounted by a pressure or' top roller, K. The comb of the dofer is not represented, it being common to the carding engine. In covering the doier with itscnrd teeth or clothing, such is not to go entirely around it, but there is to be a narrow space extending across the surface ofthe doii'er from end to end of it, in which there is to be no clothing or teeth, the circumference of a cross-section of the doifer, minus the width of the said space left unclothed, being equal, or about equal, to the width of the endless apron. The feeding-drnm or relier I, which receives the bat from the doier, (such hat bei. combed olf the doifcr and received upon 'the said roller L) has a diameter about equal to or a little greater than that of the doffer. A pulley, a, iixed on the shaft ofthe feedingroller I, has an endlcss band, b, running around it, and a pulley, c, fixed on the shaft of the roller D of the endless apron C. The said band b, in its course from one pulley to the other, is bent at or about at rightangles around a guide-post, CZ, or against two friction-rollers arranged thereon. Thus itwill be seen that there is such a connection between the endless apron, carrying and driving-roller, and the feeding-roller of the auxiliary carding engine, that the` proportions of their speeds will always be alike, whatever may be the speed of the endless apron. Thus, if at any time the speed of the main carding engine `should be increased or diminished, the speed of the delivery-roller of the auxiliary cartling engine will be increased or diminished in like proportion, so as to cause it to deliver the transverse bats at the proper velocity for them to be deposited on the hat of the apron without improper overlapping of any one of such transverse bats on that next to it and previously laid. There is also another pulley7 e, fixed on the shaft of the feed-roller I. A crossed endless band,f, goes around this pulley and another pulley,f, iixed on the shaft gof the driving-roller K of the transverse batearrier, or apparatus or mechanism for removing each transverse hat and transferring it to its proper position over and for being deposited on the endless apron. This apparatus is composed of two rollers, K L, two endless belts, M M, and a series of card-clothed bars, N N, tc. The belts work-around the two rollers, and the bars extend from one roller to the other, and are arranged at or about at equal distances asunder. The outer surface of each of the bars iste be covered with card teeth or card clothing, as shown at L.

The next part of the machine to be described is the striker, or that by which each transverse web or bat, after having been brought directly over the bat on the endless apron by the bars N N, tc., is forced off the teeth of such bars and deposited on the bat of' such endless apron. This apparatus may bc thus explained: The said striker, shown at O, is composed of a har, t', and a series of other bars, cfc c, extending from such bar z at right angles, and into thev space within the transverse carrier, each of such bars le being provided with a projection, Z, to extend from it as represented I prefer to hinge each of the said projections directlyr to its bar, as shown in the drawings, in order that they may present no impediments to the movements ofthe carrier. The bar 2' of the striker is supported by and so as to be capable of being moved vertically between two guides or standards m m, projecting upward from the frame G'. The striker is depressed at the proper times by the action of a spring, P, fixed to the frame G, and bearing upon the striker, the arrangement of such spring being as represented in iig. 1. A notched wheel, R, fixed on the shaft of the inner roller of the carrier, operates with a lever, S, whose fulerum is extended from the frame G. The longer arm of the said lever extends underneath and against a stud, m2, projecting from the striker. The notched -wheel operates on the lever so as to cause it not only tol raise the striker upward and hold it so elevated the proper length of time, but releases the lever so as to enable the spring to suddenly depress the striker in a manner to cause it to force a transverse bat off the carrier and down upon the bat of the endless apron. The shafts of the doffer H, and the feeding-drum I, are provided with pulleys n o, around which an endless crossed belt, p, travels, the same being to cause the speed of the doffer to vary with that of the feeding-drum, in` order that the bat may be delivered to the feeding-drum' at the proper rate in proportion to its speed, whether such be accelerated or retarded by the endless apron.

Having thus described my invention, what I claim as constituting the same, is as follows:

I claim the combination of the endless apron C and the feeding-drum I of the auxiliary earding engine by or with mechanism whereby the speed of the said drum may be controlled by or increased or diminished with that of the apron, substantially as and for the purpose specified.

I also claim the endless carrier and the striker, made and arranged in manner, and provided with mechanism for operating them as described.

And I particularly claim the application of the projections of the striker to their bars by hinges or mechanical equivalents therefor, in order that the projections may vibrate or move relatively to the bars, so as not to impede the motion of the carrier.

I also claim the combination of the endless apron C, the feeding-drum I, and the doifer H, by or with mechanism whereby the speeds of bothvthe drum and doifer are varied with that of the endless apron, the same I being for the purposes or objects substantially as explained.

ENOCH WAITE.
