vMy invention relates to machines for securor other cleaning implements, and an ob'ect of my invention, among others, is thepro uction of a machine of this class that shall be particularly efiicient for such urpose.

One form of machine embo ying my invention and in the construction and use of which the objects herein set out, as well as others,

-may be attained, is illustrated in the accompanying drawings, in which- I Figure 1 is a plan view of my improved machine. Figure 2 is a View in side elevation with parts underneath omitted.

Figure 3 is a view similar to Figure 1, but with some of the upper parts removed to illustrate construction of parts underneath.

Figure 4 is a detail view illustrating the relative arrangement and operationof the wire feed disc and the assembly wheel on a plane denoted by the dotted line 44 of Figure 3.'

Figure 5 is a detail view, scale enlarged, illustrating the means for securing the fibers to the binding 'strips on a plane denoted by the dotted-line 5--5 of Figure 3.-

Figure 6 is a detail View illustrating a binding strip with corrugated sides for straightening up the fibers.

In the accompanying drawings the numeral lO indicates a table of any suitable construction and upon which my improved machine may be supported, said machine comprising a base plate 11 for machine arts that are secured to and rest thereon. hese include supports 13 secured to and rising from the plate 11 near opposite sides thereof and a driving wheel supporting bracket 14 secured to the side of one of said supports to receive a driving wheel supporting stud 15 secured to and projecting therefrom and having a driving wheel 16 with a driving inion 17 secured thereto rotatably mounts on said stud, the driving wheel being suitably arranged in any desired manner to receive a belt as a means for driving it. The pinion 17 meshes with a driving ear 18 on a feed shaft 19 mounted atone en in a feed shaft supporting bracket 20 secured to the side of one 7 of the supports 13, said feed shaft alsobeing rotatably mounted in feed shaft supporting blocks 21 secured to the base plate 11, and as shown in Figure 3 of the drawin Feed belt supporting arms 22 are adjusta 1y pivotally supported at the ends of the supports 13 opposite said feed shaft, and feed belt sup porting studs 23 project from said arms toward each other to receive pulleys around whlch pass supporting feed belts 24, the opposite ends of said belts being supported by .pulleys secured to the feed shaft 19.

Retaining feed belts are supported to overlie the belts 24 to retain material, as fibers, thereon, these belts 25 being supported at one end on pulleys mounted at 0 posite ends of a retaining belt supportin shaft 26 located in a shaft supporting brac et 27 adjustably secured to a supportin bar 28 attached at its opposite end to t e sup orts 13, the opposite ends of the belts 25 eing supported on pulleys mounted on stud shafts projecting toward each other from retaining shaft supporting arms 29 secured to and pro jecting from the inner side of the supports 13, and as shown in Figure 1 of the drawings. Core feed supporting arms 30 are mounted at one end on the bar 28, the opposite ends of said arms receiving the ends of a shaft rotatably supporting a sleeve to be hereinafter specifically referred to and to which a core supporting feed disc 31 is secured, said disc having a peripheral groove to receive a wire 32 that is incorporated as a core in the structure that is formed in the machine. A- guard 33 is located about a portion of the periphery of the disc 31jto retain said wire in the groove in the disc, and a tensioning device 34 of any suitable construction may be employed to preserve a proper tension on the wire 32.

In the operation of the machine thus far described a binding strip 35, of V-sha e in cross section, and of indefinite lengt is passed into and through a tube 36, emerfi'ng therefrom and adacent to an assembly w ee 37 mounted upon and to rotate independently of the shaft '19. This assembly wheel comprises an important feature of my invention and it has an assembly groove 38 and fiber adj usting teeth 39 arranged in two rows, one row on each side of the groove 38. These teeth are preferably pointed and taper to a wider dimension at their bases, and the strip is projected into and through said-groove on one sideof the wheel 37.

The delivery ends of the feed belts 24 and 25 are located adjacent to'th assemblywheol 37, and fiber guides 40 are secured to the fiber shaft supporting blocks 21, and project upwardly on opposite sides of the assemby wheel 37, these guides being inclined in a direction crosswise of said wheel to engage the fibers as they are moved along and bend them so that their opposite ends on the outer sides of the wheel 31 will be closed toward each other, said fibers being held at their centers by the wire 32 within the groove in the binding strip 35 during such bending operation.

The binding strip 35 with the fibers held by the wire 32 therein is drawn through a groove in the assembly wheel 37 by mechanism to be presently described, said wheel being rotated by the movement of the strip 3 along and within the groove in the wheel. As

the fibers are moved into the angle between the approaching curved surfaces of the bottom of the groove in the wheel 37 and the wire 32 there is a tendency for the fibers to be crowded backwardly and the teeth 39 are,

therefore, provided to counteract this tendency and maintain the fibers in or restore them to an upright position. Other means may be provided to effect this result, for instance, as by corrugating the wall of the bind ing strip 35 in the direction of depth thereof and as indicated by the numeral 69 in Figure 6. i

Compressing wheels 41 are secured to shafts 4 243 rotatably supported by a. bearing block 12 secured to and rising from the top of the table 10. The shaft 42 has its hearing formed directly in the block 12 while the shaft 43 is mounted in a bearing in an adjustably mounted block 44 located in an opening in the block 12 and with its lower end resting upon the table 10. Gibs 45 overlie the upper end of the block 44 and form the upper side of a guideway in which the block 44 has a slight movement to compensate for various thicknesses of material passing between the wheels 41. The opening in the block 12, just hereinabove referred to, is closed at one side by a cover plate 46 that is secured to said block as by means of screws. A hearing bracket 47 is secured to said block 44, and a compressing wheel driving shaft 48 is mounted in bearings in the lower ends of the plate 46, the bracket 47 and a similar bracket 63 secured to and projecting from the side of the block 12, as shown inv Figure 3, and below the bottom thereof. Said shaft has bevel pinions 4950 in mesh with bevel pinions on the lower ends of the shafts 42 and 43. The pinion 49 has a hub rotatably mounted in the bracket 47 and said pinion is splined to the shaft 48 so that in the adjusting movement of the block 44, saidblock, the shaft 43, and bracket 47, as well as the intermeshing pinion, move as a unit.

The shaft 48 is driven by a. bevel pinion thereon in mesh with a bevel'pinion on a con- 'necting shaft 51, the latter having a gear 52 in mesh with a pinion on a driving shaft 53 mounted in bearings on the table 10 and driven as by means of a belt engaged with a driving pulley 54 secured tosaid shaft.

An adjusting bar 55, secured at one end to the block 44, passes loosely through a hub 56 on the cover plate 46, said bar at its opposite end being loosely secured to an adjusting lever 57 pivotally mounted in bearings 58 in a bracket secured to the side of the table 10, and as shown in Figure 1 of the drawings, said lever having an arm projecting under the table to the opposite side thereof and havshown. The bar 55 is mounted loosely enough to permit the lever 57 to swing on its pivot, and the arrangement just described provides means for pressing one of the wheels 41 into yielding contact with the structure passing between said wheels and being formed thereby, so that one of said wheels may yield to compensate for any variation in thickness of the material passing between the wheels, and yet at the same time exert pressure enough to accomplish'the purpose for which it is designed.

The formed strip60, comprising the binding strip 35, the wire 32 and the bristles or fibers 61, all tightly compressed with the fibers and wire firmly secured within the binding strip, passes through a guide 62 after which it may be disposed of in any suitable manner, as by being cut into such lengths as may be desired for the formation of brushes or similar articles.

A feed disk supporting shaft 64 hereinafter mentioned is permitted a vertical adjustment by reason of the pivotal support of the arms 30, the disk 31 in operation resting upon the wire in the groove in the disk and said wire resting upon the fibers in the binding strip 35. The fibers within the binding strip therefore receive the weight of the disk, the shaft 64 and the arms 30 and parts carried by said shaft and including a guard support 65 carrying the guard 33 and a block 66 supporting the arm 67 at the end of which the tensioning device 34 is'located.

Stops 68 in the form of screws project downwardly from the upper ends of the supports 13, against the shaft 64, and these stops may be employed to prevent the disc 31 from moving too far away from the binding strip 35 and the fibers therein, said stop screws therefore preserving the proper amount of pressure of the feed disc upon the mass underneath it.

The wheels 41 are provided withperipheral teeth that engage the fibers to prevent backward inclination thereof at the time of compression of the fibers in the stri 35 and in a manner similar to that hereinbe ore described as to the wheel 37, the teeth of the wheels 41 meshing one with'the other, and as shown in Fig. Bofthe drawings, this comprising another important feature of my invention.

"In accordance with the revisions of the patent statutes I have descri d the principles of operation of my invention, to ther with the apparatus which I now consi er to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention ma be carried out by other means and appli to uses other than those above set out.
