Description
APP~RATUS FOR WIPING WASH~D V~HICLES
The present invention relates to vehicle wiping ap-paratus for use in automatic carwash systems, and primarily relates to apparatus for wiping and drying vehicles emerging from the wash area of an automatic carwash system and which results in more ef~icient wiping of the vehicle.
DESCRIPTION OF THE PRIOR ART
The following patents all relate to wiping and drying assemblies for use in automatic carwash systems:
Canadian Patent 872,346 June 1, 1971 Weigele et al Canadian Patent 1,012,711 June 28, 1977 Evans U.S. Patent3~683,441 August ].5, 1972 Fromme U.S. Patent3,765,043 October 16, 1973 Lesser U.S. Patent3,914,818 October 28, 1975 Fromme U.S. Patent4,166,302 September 4, 1979 Kim U.S. Patent4,166,303 September 4, 1979 Fromme The apparatus described and claimed in U.S. Patent ~,166,302 is yenerally similar to the arrangement of the present invelltion and over which the present invention is an improvement.
In the assembly of U.S. Patent 4,166,302, the width of the path of wip.ing movement is only the width of the sequentially aligned wlping towels with the result that to ensure that all of the ve-hicl.e is contacted by the towels, the rate of the movemen-t of the towels and/or rate of movement of the vehicles must be relatively slow.
With the apparatus of this U.S. Patent, and to provide as wide a wiping sweep as possible, the wiping towels are relatively wide which increases their bulk wi.th the result that the necessary Elexibility to contact and wipe all portions of a vehicle is ~0 ~
lost. Additionally, the excess bulk of the towels may on occasion result in damage to portions, hood ornaments, antennas, of the vehicles being wiped.
DESCRIPTION OF THE PRESENT INVENTION
The present invention provides an improvement to known apparatus which will enable increased rate of movement of drying towels and/or increased rate of movement of vehicles through the wash while at the same time ensuring that all possible portions of the vehicle are wiped.
The present invention accomplishes these advantages by increasing the width and area of wiping sweep for each pass of the drying towels by staggering the positioning of various of the towels laterally with respect to the path of movement of the towels.
Additionally, and by staggering the positioning of the various of the towels laterally with respect to the path of move-ment, each towel may be of less width (and hence less bulk) than towels conventionally used and this ensures that each towel more easily conforms to the shape of the vehicle for better wiping while minimizing the possibility of damage to windshield wipers and ~0 antennas, and with the added advantage of increased visibility for the occupant of the car and the carwash attendant.
Moreover, and by maximizing the sweep for each path of movement of the towel, it is possible to minimize the space re~uired for the installation of the assembly with reduced cost for installation and maintenance.

DETAILED DESCRIPTION OF ACCOMPANYING DRAWINGS
The accompanying drawings will now be described in detail and wherein like reference numerals refer to like parts.
The assembly consists of an endless track 2 of oblong configuration having rounded ends which is elevated to a height to permit the passage of washed vehicles thereunder and which is supported in such elevated position by suitable frame members 4, ~0 cxtending downwardly from the ceiling of the carwash building.
Carried by the endless track 2 are chain link support brackets 6 having roll,ers 8 which engage with the endless track.
A rod 10 (see Figure 2) extends vertically downwardly from each bracket 6, and each rod 10 pivotally carries the respective ends of links 12 which together form an endless chain shown generally at 14 in Figure 1.
Each link 12 has a number of vertically elongate openings 16 which conveniently have a two-fold purpose, the first providing means Eor supporting the drying towels (which will be discussed in detail below) and the second for providing means for imparting 591~
movement to the endless chain 14 in the direction of arrows 18 as shown in E~igure 1. The elevated framing 4 carries a motor 20 with related speed reduction mechanism 22 which drives a cogged wheel 24 (shown only partially in Figure 1) which is ro-tatable about a vertical axls and whose cogs (not specifically shown) engage in the top portions of the openings 16 to cause movement of the endless chain. A similar cogged wheel (not shown) which is not motor driven is provided at the other end of the endless track to provide support and guidance for the endl~ss chain 14.
Suspended from the links 12 are a plurality of vertically elongate drying cloths or towels shown generally at 26. With res-pect to Figure 6, each towel may conveniently consist of an upper strip of carpet (or the like) material 28 which carries two individual lengths, upper 30 and lower 32, of chamois material, or chamois~type material, secured thereto. For replacement and cleaning, the lengths 30 of chamois material are preferably re-movably secured to the strip of carpet material 28 and this can conveniently be done through the use of hook-and-eye fastening matcrial of the type well known as VELCO (registered trade mark).
~he upper length 30 of chamois material is secured only at its top to the strip oE makerial 28 and the VELC~O securement may be overlaid by a flap 34 of carpet material which covers the joint to yuard against the chamois length being pulled away from the carpet strip as it is drawn over a vehicle. Conveniently, the lower end of the upper length 30 of chamois material overlies the top edge of the lower length 32 avoiding the necessity of having to provide a related flap of carpet material.
When the towels are all suspended in the manner as shown in Figure 17 and the endless chain 14 is driven for move-ment in ~he direction of arrows 18, an automobile to be wipedand dried is then moved or drawn in the direction of arrow 35 through the moving towels to e~fect the wiping and drying as is convenkional.
During their drying contact with a vehicle, the chamois lengths 30, 32 remove moisture from the vehicle and this mo.isture can conveniently be extracted from the chamois lengths by conven-tional.ly passing the strips over a vacuum tube 36 which is connected to a vacuum source 38. The portion of the tube facing the oncoming towels may be provided with an elongate slip or openings ~not specifically shown) through which moisture from the towels is drawn by suction action as the towels pass over and in contact with the vacuum tube as shown in Figure 1.
By positioning various of the towels 26 in relatively staggered relationship with respect to the endless chain 14 a broad path of wiping sweep can be obtained using relatively narrow towel strips to obtain the advantages ouf the invention as dis-cu.ssed above.
One suitable method of positioning the towels in re-latively staggered relati.onsh.ip is shown in Figures 2, 4, and5, and as shown in Figures 2 and 5, a carpet strip 26' can be centrally positioned with respect to its supporting chain link 12 by means of a center support rod 40 carried by the chain link and which extends on each side thereof to be received within openings provided on each side of the strip as shown in Figure 5.
Towelling strips 26" are then positioned on each side of the chain links as shown in Figures 2 and 4, by the provision of pro-jecting support :rods 42 having inner ends secured to the chain links with the strips 26" being suspended adjacent the outer ends of the rods in convenient fashion such as by inserting the rods 42 through upper openings 44 provided in the strips as shown in Figure 6. The projecting support rod ~2 may be threaded to receive washers ~4 and nuts 46 to hold the strips in position as shown in Figure ~.
Figure 3 is a top schematic view illustrating a pre-Eerred sequential positioning of adjacent strips on the endless chain, but it will be appreciated that other sequential position-ing could be employed without departing from the scope of inventive concept. In Figure 3, two strips 26' are centrally positioned with respect to the endless chain 14 followed by a strip 26" positioned laterally offset to one side of the chain, followed by two further centrally positioned strips 26', then followed by a further strip 26" laterally offset from the chain on the other side; this repeating secluential order being followed throughout the length of the chain.
It will be appreciated, however, that other sequential arrangements could be employed such as by providing only one centrally positioned strip 26' between laterally offset strips ~0 ~6".
The relatively narrow width of the chamois lengths (which may be of the order of 6" wide by 21" long) allows them to have less bulk to more easily conform to the shape of the automobile for better wiping and drying. By way of example, each link 12 of the chain may be approximately 12" long, carrying three strips 28 with six lengths 30, 32, with the strips being approximately equally spacecd. The first strip on each link is centered, the seconcl strip is laterally offset to one side of the link about lQ" Erom center and the third strip is centered. In the next link 5~i~
the offset strip is on the other side and this arrangement provides a wiping path having a width in the neighbourhood oE 20" which provides for greater flexibility in wiping and visibility as discussed above.
In practical application, the endless track 2 may be of the order of 14' long by 2' wide from which 90 towelling strips 28 each carrying two chamois lengths 30, 32, are suspended, providing 180 chamois wiping lengths.
The present invention relates to vehicle wiping ap-paratus for use in automatic carwash systems, and primarily relates to apparatus for wiping and drying vehicles emerging from the wash area of an automatic carwash system and which results in more ef~icient wiping of the vehicle.
