Definitions

  • ABSTRACT A street sweeping broom which is comprised of a rotary helical brush strip tightly secured about a rigid cylindrical core.
  • the brush strip is of generally conventional construction and includes a plurality of reversely bent bristles with the bights thereof being maintained within a channel member by an anchoring wire and by the crimping of the channel member at spaced locations along the length thereof.
  • Each of the ends of the helical brush strip is secured to a guide member which also supports the coil directly adjacent to the end of the brush strip.
  • a ring having a plurality of circumferentially spaced slots is secured to each end of the core, and the guide members are attached to the rings by means of an inclined, inwardly projecting tang which allows movement of the guide member in only one rotational direction upon the ring.
  • ratchet-type mechanisms are provided to secure each end of the brush strip to the core which mechanisms act to automatically take up any slack in the brush strip during the usage thereof in order to maintain it in tight engagement with the core.
  • a typical construction for a rotary power brush such as might be used on street sweepers for example, comprises a generally cylindrical core member about which a helical brush strip is tightly wrapped.
  • the brush strip includes a channel having a tightly bunched, continuous series of reversely bent bristles secured therein.
  • the bristles are arranged to be secured within the chan nel at their bight portions by means of an anchoring wire or cable which extends the full length of the brush strip.
  • an anchoring wire or cable which extends the full length of the brush strip.
  • one end of the brush strip is fastened to the core by means of a slack accumulator device which comprises a flexible cable attached to the end of the brush strip and to the end face of the core so as to allow the brush strip to rotate in one direction if slack develops along the length thereof but preventing it from rotating in the opposite direction wherein it would unwind from the core.
  • a slack accumulator device which comprises a flexible cable attached to the end of the brush strip and to the end face of the core so as to allow the brush strip to rotate in one direction if slack develops along the length thereof but preventing it from rotating in the opposite direction wherein it would unwind from the core.
  • the attachment of the aforementioned cable to the end face of the core can be loosened, and the brush strip can be pulled tighter about the core to remove such slack before reclamping the cable to the core.
  • the brush strip can be maintained in a fully tightened condition on the core so as to prevent damage to the strip such as mightoccur if the'end of the strip were permitted to move freely on the core and strike its retaining mechanism.
  • the rotary sweeping brush structure shown in this patent also includes a helical brush strip which is arranged to be rigidly secured about a cylindrical core element. However. no channel means are provided upon .the surface of the core element for holding the brush strip coils in place. Instead,
  • the brush strip are provided with.
  • oneway clutch devices which provide for an automatic positive takeup of any slack in the brush strip as soon as it occurs.
  • the need for the channel is allegedly obviated since the automatic take-up provided .by the brush strip mounting means will maintain the brush strip in, tight engagement with the core at all times.
  • Slack accumulator devices are mounted upon the ends of the Gould et al core, and the ends of the brush strip are provided with extensionstgrooved or threaded in actual practice) which are adapted to move through such slack accumulator devices in one direction while being restrained from movement in the opposite direction. As the brush strip is tightened about the core the extension at the end thereof moves past the slack accumulator device and extends freely adjacent to the end of the core.
  • the apparatus of the present invention comprises a rotary sweeper broom structure which, like the broom structure shown in prior U.S. Pat. No. 3,750,225, is provided with means for allowing an automatic continuous take-up of the slack which inherently develops in brush strip coils that are helically wrapped upon an underlying, generally cylindrical core element.
  • a rotary sweeper broom structure which, like the broom structure shown in prior U.S. Pat. No. 3,750,225, is provided with means for allowing an automatic continuous take-up of the slack which inherently develops in brush strip coils that are helically wrapped upon an underlying, generally cylindrical core element.
  • Such continuous take-up of the slack is arranged to be truly unlimited, and, in fact, no hand tightening of any sort is required when the brush strip is initially placed on the core element prior to the use of the brush under load conditions, i.e., in a street sweeping situation.
  • the coiled brush strip can be merely slipped into place loosely over the core and attached loosely at its ends to the ends of the core, and then the assembled broom can be placed directly upon the powered street sweeper ready for use. Rotation of the brush in place and under load then provides the proper tightening of the brush strip coils.
  • no helical track means is generally required to keep the brush strip coils in the desired uniformly spaced relationship.
  • the brush strip is arranged to be held in place on the core by at least one ring member which is attached directly to the core at one end thereof.
  • This ring member includes a series of spaced steps or recesses which extend circumferentially about the entire cylindrical surface of the ring member.
  • a guide member is securely attached to the end of the brush strip adjacent to the ring member and is arranged to ride upon the surface of the ring member as the slack is removed from the brush strip.
  • the guide member is provided with means that successively engages the spaced stops on the face of the ring member so as to permit relative rotational movement therebetween in one direction but preventing such relative rotational movement in the opposite direction.
  • the end of the brush strip can rotate endlessly about the ring.
  • the guide member is provided with means for slidably securing the brush strip coil at a position spaced one coil length from the end of the strip; this serves both to assure that the guide member will always be properly aligned with the ring member so that binding or jamming will not occur and to assure that the end coils of the brush strip will be properly positioned at the end of the core.
  • the present invention possesses several distinct advantages over the prior art rotary coiled brushes, particularly the device shown in the aforementioned prior U.S. Pat. No. 3,750,225.
  • the guide member is slidably attached to the brush strip one coil length from the end of the strip so that the end two coils of the brush strip are maintained in the proper closely spaced position close to the edge of the core where full and effective sweeping is essential.
  • the guide member in the present invention will always be aligned with the ring member whereby binding or jamming will not take place so as to prevent the desired slack take-up movement from occurring.
  • Another important advantage of the rotary brush structure of the present invention is that even after full slack take-up there is no free unsuported end of the brush strip which might become entangled in the dirt shoes or other mechanisms at the sides of the rotary broom structure.
  • the novel slack accumulating device of the present invention thereby comprises the aforementioned ring member and guide member, and such slack accumulating device may be provided at each end of the core if the brush strip is subject to loading in either rotary direction. Also, although it is preferred to attach the ring member to the core and the guide member to the end of the brush strip, it is possible to reverse this arrangement, i.e., attach the ring member to the end of the brush strip and the guide member to the end of the core, and still obtain the major advantages of the present invention.
  • FIG. I is an isometric view of one end of a rotary coiled broom which embodies the present invention with the coils of the brush strip thereof being broken apart and separated from the core for the purposes of illustration.
  • FIG. 2 is a fragmentary longitudinal section of the end 'of the rotary coiled broom shown in FIG. 1.
  • FIG. 3 is a reduced section taken along the line 3-3 of FIG. 2 with the brush strip being removed from the guide member to which it is attached for the purpose of clarity.
  • FIG. 4 is an enlarged section taken on the line 4-4 of FIG. 3 and illustrating the ratchet-type connection of the guide member with the underlying ring member.
  • the rotary broom of the present invention will be seen to comprise a generally cylindrical core 10 about which is wrapped a helical brush strip 12, the brush strip extending the full length of the core in rather closely spaced coils (as is conventional).
  • An axle I3 is arranged to support the core Upon a street sweeping machine (not shown) in the conventional manner.
  • the brush strip is entirely conventional in construction and comprises a coiled metallic supporting channel 14 within which is received a plurality of reversely bent and closely bunched bristles 16 that extend throughout the length of the brush strip.
  • Each of the bristles is secured at the bight thereof within the supporting channel 14 by means of an anchoring wire 18 which. in the described embodiment of the invention. is a twisted pair anchoring wire as disclosed in prior US. Pat. No. 3,137,021.
  • the bristles are additionally retained in the channel by intermittently spaced crimped portions 19 (FIG. 1) spaced along the outer side edges of the channel 14.
  • the improvement representing the present invention basically comprises the provision of means whereby at least one end of the brush strip 12 is secured to the end of the core I0 so that continuous positive accumulation of slack within the brush strip is obtained.
  • a cylindrical ring member 24 is loosely assembled about the end surface of the core.
  • This ring member comprises a relatively large cylindrical flange portion 26 and a relatively short cylindrical flange portion 27 which flange portions are separated by a radially outwardly extending track portion 28.
  • the short flange portion 27 is positioned directly adjacent to the end of the core and is provided with a series of apertures 30 spaced about its circumference. Selected ones of the apertures 30 are arranged to receive cotter pins 32 (as shown in FIG. 1) in order to permit the attachment of the ring member to the core.
  • the large flange portion 26 of the ring member includes a continuous series of uniformly spaced slots 34 which extend about the entire cylindrical surface of the ring member.
  • the end of the brush strip 12 is arranged to be securely attached to a clip or guide member that is arranged to ride upon the track portion 28 of the ring member 24 and is provided with means whereby it is permitted to move in only one rotary direction upon the surface of the ring member.
  • This guide member as best shown in FIGS. 2 and 3 of the drawings, comprises a clip which has a generally U-shaped body portion 42 arranged to receive the end of the brush strip.
  • the side walls of the body portion 42 of the guide member are provided by a plurality of tabs 44 the upper ends of which are bent transversely (as shown in FIG. 1) into closely spaced adjacent relationship to securely lock the guide member about the channel 14 of the brush strip and within the radially extending bristles 16.
  • a pair of reversely bent ears 46 extend laterally outwardly from the body portion 42 of the guide member and are adapted to be slidably received upon the track portion 28 of the ring member so that the guide member can freely slide about the circumference of the ring member.
  • a pair of flanges 48 at the ends of the guide member extend laterally in the opposite direction from that of the ears 46 and, shown in FIG. 2 of the drawings. underlie and serve to slidably support the brush strip at a position spaced one coil length from the end of the strip. This arrangement serves to properly main tain the end coils of the brush strip close to the end of the core where they are needed.
  • flanges 48 are bent so as to extend radially outwardly and thus serve to maintain the coils of the brush strip on the guide member. It will also be recognized that the flanges 48 may extend along the core 10 for a distance sufficient to support several coils of the brush strip if it is desired to bunch the coils at the end of the core.
  • the body portion 42 thereof includes a radially inwardly struck tang 50 which extends rearwardly to the direction of travel of the guide member and at an inclined angle thereto.
  • This tang is arranged to successively become engaged in the spaced slots 34 of the ring member as the guide member is slid about the circumference of the ring.
  • the configuration of the tang is such that it will pass over the slots when the guide member and the brush strip held thereby are moved in one rotary direction (indicated by the arrow in FIG.
  • a second guide member or clip (FIGS. 1 and 2) is secured to the brush strip at a position spaced or one-half a coil length, from the end of the strip.
  • This second clip 60 comprises a generally U-shaped member one side wall of which is formed by a tab 62 that is bent transversely at the upper edge so as to overlie the channel 14 of the brush strip and lock the brush strip thereto.
  • the guide member 60 also includes a pair of laterally extending reversely bent ears 64 adjacent to the tab 62 for permitting the guide member 60 to ride upon the track portion 28 of the ring member in the same manner as that of the first guide member 40. It will be recognized that if the guide member 40 is provided with flanges 48 which are lengthened so as to support several coils of the brush strip, then the second clip 60 must be widened accordingly.
  • the aforedescribed means for securing a brush strip about a core ofa rotary sweeper broom may be utilized on virtually any conventional coiled brush strip-core construction.
  • the guide member 40 is attached to the end coils of'the brush strip as shown and is merely placed upon the radially extending track portion 28 of the ring member.
  • the operator who is to do the actual changing of thebrush strip will therefore be provided with a replacement brush strip which has attached thereto (on at least one end thereof) a guide member and a ring member in assembled relationship.
  • To mount the brush strip upon the core it is then necessary to merely attach the ring member 24 to the end of the core with the cotter pins 32 as shown.
  • the brush strip tightens upon the core when the brush is subjected to loading (i.e., brushing) forces, the pull on that portion of the brush strip which is engaged by the supporting flanges 48 of'the guide member will force the guide member downwardly upon the ring member.
  • the end of the brush strip which overlies the projecting tang 50 will always be in secure engagement with the ring member, and the guide member will always be aligned properly with the ring member to prevent binding therebetween.
  • the ring member is merely removed from the end of the core by loosening the cotter pins 32, and a similar attachment means or fixed eon nection at the other end of the core is also removed. Then, the brush strip is allowed to unwind slightly so that it becomes loose enough on the core so as to permit the entire brush strip assembly to be slid axially from the core.
  • the brush strip may be tightened on the core merely by applying a sweeping load to the bristles of the brush strip.
  • a preferred way of tightening the brush strip upon the core when the rotary broom is to be used in a powered street sweeper is to mount the assembled core and brush strip on the street sweeper machinery with the brush strip being in the aforementioned loosened condition upon the core.
  • the coils can then be spaced by hand in the desired arrangement on the core as they will be free to slide axially on the core at this time.
  • the broom-core is next accelerated rapidly while it is elevated above the ground surface.
  • the rotary coiled broom assembly of the present invention provides a means whereby a conventional helically coiled brush strip can be tightened in place upon the conventional supporting core element. Since the slack adjustment mechanism of the present invention provides an endless amount of adjustment and does not leave a freely extending end or projection of the brush strip, there is no requirement whatsoever for initial hand tightening of the brush strip upon the core during the broom assembly. Thus. the operator need do no more than merely slide the brush strip upon the core, attach some cotter pins or the like, and then mount the assembly upon street sweeping equipment with the coils in the proper spacing and such street sweeping equipment will then be ready to operate.
  • the take'up device of the present invention also eliminates the necessity for providing a helical track or similar fixed spacing means upon the surface of the core.
