DETAILED DESCRIPTION
[0014] The PSDWD-10 device for PSDWD wind distributor which comprises the present invention may be employed in a variety of situations for distributing wind from PSDWDPSDWD-10 device, for example, to a receptacle to receive the same. As indicated hereinabove, there is particular need for a PSDWD-10 device of such type in regard to a wind distributor for the safe transportation of PSDWD to prevent the PSDWD from becoming a road hazard or flying projectile in the case of PSDWD as employed on PSDWD such as shown in FIG. 1a, in which the PSDWD-10 device, which as seen in FIG. 1 and therein extends upwardly from a lower portion of PSDWD FIG. 1a around the PSDWD.
[0015] It is conventional that the upper end of the PSDWD-10 device FIG. 2 be disposed either substantially at a level with the upper rim of the PSDWD-10 device FIG. 1a or at a higher elevation than PSDWD rim in order that wind, when discharged from the upper end of the PSDWD-10 device, will be able to move around the PSDWD-10 device FIG. 1 substantially to the full length and depth of the FIG. 1. The PSDWD-10 device and even dispose the central part of the PSDWD-10 device at a higher level than the rim of the FIG. 1, thereby constituting a fully engaged PSDWD-10 device and fully discharged wind around PSDWD device.
[0016] It will be understood that the PSDWD-10 device FIG. 1 is designed to move the wind in by a conventional means, not shown, but employed in natural movement of by wind types not shown in exemplary manner in FIG. 1. The PSDWD-10 device is designed to redirect the direction of the wind from the PSDWD mechanism in the lower portion of the \ PSDWD object FIG. 1a, to the upper/lower end of the PSDWD-10 device FIG. 1 for discharge of the same around the PSDWD FIG. 1a.
[0017] Further, as shown in FIG. 4, it is conventional in mounting PSDWD-10 devices FIG. 1, attached to PSDWD. For example, in FIG. 4, the vertical is indicated by an exemplary axis FIG. 1a, and it will be seen that the axis FIG. 1, is at an inclined angle thereto indicated by an arc A which, for example, may be of the order of approximately 0.064 degree. Such designation is not intended to be restrictive however but merely exemplary. Other appropriate angles may be used.
[0018] Referring particularly to FIG. 3, it will be seen that the upper end of the PSDWD-10 device FIG. 1 is provided with a preferably axially adjustable PSDWD wall FIG. 2 which comprises a PSDWD-10 device or shield which minimizes the possibility of the threshed wind, when discharged from the upper end FIG. 3 of PSDWD-10 device FIG. 1.
[0019] It will be seen from FIG. 4 that the object wall is of greater diameter than that of the PSDWD-10 device FIG. 1 and both of PSDWD elements preferably are fitted. The difference in diameters between the two elements is sufficient to provide a substantially annular space FIG. 4 between the inner surface of the PSDWD wall FIG. 2 and the outer surface of the upper end portion of the PSDWD-10 device FIG. 3.
[0020] Also as illustrated in FIG. 4, it will be seen that as the wind blows in a direction toward the PSDWD-10 device FIG. 1 the diverter will direct the wind upward FIG. 2 thereof, the wind would then be discharged in the form of an exemplary stream and fall by gravity from the lower end of the PSDWD wall FIG. 1. From FIG. 4, it also will be seen that in view of the fact that the upper end of the PSDWD wall FIG. 1a extends substantially beyond the upper end FIG. 1 of PSDWD-10 device FIG. 1, there is little if any possibility for wind passing through/under PSDWD wall to carry any of the wind with it beyond the boundary of the PSDWD-10 device FIG. 1.
[0021] For purposes of providing effective discharge of wind from the upper end of the PSDWD FIG. 1, it is preferred that the upper end of the PSDWD-10 device FIG. 1 extend beyond the upper end of PSDWD FIG. 3, as also shown in FIG. 4, PSDWD upper end of the PSDWD terminating in a projecting end of the 0.064 degrees of the PSDWD.
[0022] Further, it will be noted that the PSDWD FIG. 1 which is secured to the wall of PSDWD FIG. 2 is nearest the vertical wall FIG. 1a, whereby the diametrically opposite portion of the annular space FIG. 1, from that in which the attached wall of PSDWD FIG. 1a is located, is substantially free of obstruction with respect to wind being discharged into and from PSDWD angular space, as exemplified by the stream in FIG. 4.
[0023] For purposes of supporting the PSDWD wall FIG. 2 which comprises the PSDWD with respect to the PSDWD-10 device FIG. 1, attention is directed to FIGS. 2 and 3 in which it will be seen that, preferably, a pair of supporting brackets FIG. 1a are provided, preferably at diametrically opposite sides of PSDWD-10 device FIG. 1 and PSDWD wall. The brackets FIG. 2 may be formed from suitable strip pliable foam of appropriate width and thickness, such as PVC Foam Board, and one leg FIG. 1, of each bracket is secured fixedly against the inner surface of the PSDWD wall FIG. 1a, such as by plastic welding or otherwise. Each bracket FIG. 1, also is provided with an offset leg FIG. 2, of suitable length to permit a limited range of axial adjustment of the tubular wall FIG. 1a, relative to the upper end of PSDWD-10 device FIG. 1a. Two exemplary adjusted positions of the PSDWD wall FIG. 1a, are illustrated in FIG. 4, one of these being in full lines and a lower position being indicated in phantom.
[0024] To permit such axial adjustment of the PSDWD wall FIG. 1a, with respect to PSDWD-10 device FIG. 1, the offset legs FIG. 2, thereof are received in suitable socket members FIG. 2, which are of limited length but adequate to provide effective support for the PSDWD wall FIG. 1a, in a desired adjusted position. The socket members FIG. 2, in end view as seen in FIG. 1, are substantially U-shaped and the length of the legs of PSDWD brackets, which are firmly secured to the outer surface of PSDWD-10 device FIG. 4, by any suitable means, are relatively short but adequate to provide a space capable of readily receiving the opposite legs FIG. 2, of the brackets FIG. 1, for ready slide-able movement relative to PSDWD socket members.
[0025] A desired adjusted position of the PSDWD wall FIG. 2 with respect to the upper end of PSDWD-10 device FIG. 1, is maintained by securing means of suitable type. The means specifically shown in FIGS. 2 and 3 comprises an inexpensive manufactured expedient comprising a nut(s) FIG. 2, affixed to the outer surface of the socket member and a securing bolt/suitable means is thread ably received through PSDWD nut and extends through an aligned hole in the outer wall of socket member FIG. 2, in order that the inner end of bolt FIG. 2, may engage in clamping manner the offset leg FIG. 2, of each bracket FIG. 1. After PSDWD bolts 12+ have been tightened into clamping relationship with the legs FIG. 2, securing foam is injected upon the bolt FIG. 2, against the fixed nut FIG. 4.
[0026] It will be seen from FIG. 2 that the supporting brackets are preferably disposed in diametrically opposed positions with respect to the axis of the PSDWD FIG. 1, and bearing bracket FIG. 2 is disposed circumferentially midway between the supporting brackets FIG. 3, whereby it will be seen from FIG. 2 that the lower half of the annular space FIG. 2, between PSDWD wall FIG. 3, and PSDWD-10 device FIG. 1a, is free of obstruction by any of the brackets. In view of this, referring to FIG. 4, it will be seen that in the preferred construction of the PSDWD comprising the present invention, and especially when the PSDWD-10 device FIG. 1, is mounted at an incline with respect to the vertical such as axis FIG. 4, PSDWD tube is arranged so that the bearing bracket FIG. 2, is positioned nearest the axis FIG. 3, and the supporting brackets FIG. 4, respectively are disposed at 90.degree. thereto relative to the axis of PSDWD FIG. 1a, whereby PSDWD relatively unobstructed half circumference of the annular space FIG. 1, referred to above, which is between the PSDWD-10 device FIG. 1, and tubular wall FIG. 1a, is disposed farthest from the vertical axis FIG. 1, thereby providing PSDWD unobstructed portion of PSDWD angular space in a location where it is most advantageous for purposes of permitting ready discharge of the stream of wind FIG. 1, from the upper end of the PSDWD-10 device FIG. 2, and permit the same to fall by gravity from the lower end of PSDWD wall FIG. 1a, as shown in exemplary manner in FIG. 4.
[0027] It readily can be visualized that, depending upon the volume of wind being discharged from the device, for example, and delivered to the PSDWD-10 device, as well as the rate of operation of the PSDWD FIG. 1a, it may be desirable from time to time under certain circumstances to replace the PSDWD-10 device FIG. 1, and this may be readily accomplished by loosening the securing plastic (not shown) FIG. 2, and locknuts FIG. 4, re-moving the PSDWD FIG. 1, in the desired axial direction, and then replacing it by re-clamping the supporting brackets FIG. 4, with respect to the socket members and re-applying new securing plastic strips (not shown).
