4 Claims. ((11. 15-246.5)
This invention relates 'to a device for removing'leaves and other foreign solids from the floor of a'swimming pool and the like.
One of the objects of this invention'is the;provision of a'simple, economically made, rugged, and easily manipulated device for removing leaves, and other foreign solids from the bottom of swirnming pools, and which device does not require any power driven parts nor water or air under pressure, in order to operate it for accomplishing the desired results.
At the present time expensive vacuum type cleaners are employed for removing the silt andrelatively fine foreign matterfrom the floors of swimming pools. Large leaves and many other solids are too "bulky to readily pass through the restricted'throat of a 'cleaner'of this type, and the throat and other parts of the cleaner tend to: become clogged, thus rendering'thecleaner inoperative, orv else noticeably impairing its efficiency.
'One of the objects of this invention is theprovision of a relatively cheap and simple device that is adapted to quickly and easily remove from the floor of a pool such solids as would impair the efliciency ofthevacuum cleaner type of cleaner. Since cleaners of the vacuumactuated type are now used more frequently thanis required, in order to remove certain larger solids that may quickly be removed with the cleaner of this invention, the provision of the present cleaner will reduce the necessity for using the vacuum type cleaner, except at such rare inter vals as may occur when very fine silt or the likesettles out of the water. -Such silt usually .comesfrom dust, hence is slow in accumulating.
The difficulty of using a mechanical device for removing leaves and other solids from a pool,is.mainly due to the fact that the leaves on-the floor of the pool, when influencedby the current produced in moving'the device through the water tend to float awayfrom the device, or to swirl into the-current that follows the .device .in its movement through the water.
The present invention overcomes the above difliculties. The user merely moves the device over the floor. of thepool to the leaves or materialto be removed andthe leaves will readily enter the device and be caught, and-any leaves or other material onthe floor and at the sides of .thepath of the device will remain undisturbedfor beingquickly caught upon moving thedevice to them.
One ofvthe objects of the inventionis fthe provision of arcleaner that will have the advantagesabove described. .Otherobjects and advantageswill:appearin the;descrip- .t-ionland .drawings, one .of whichi-s the provision of :a cleaner that is quickly and easily adjustable for eflicient ly removing; difierent sized leaves .and. the. like, from a pool. Where a swimming pool is located -nnder or near trees,.-;such as sycamore trees,-the leaves falling :intothe poolwill be many, times larger: than the, leaves. from many other typesoftrees, such as elm etc.

Fig. 2 is a side elevational view of the cleaner .of Fig. 1.
'Fig. 3 is an enlarged front elevational view ofzthe cleaner of Fig. 2.
Fig. 4 is a side view of the bag on the cleaner, only part of the cleaner being shown with said partin section and the bag being in section where it isconnectedwith the cleaner.
In detail, the cleaner illustrated in the drawings comprises what may be called a scoop, and which sscoop has a bottom 1, top 2 and opposedside walls generally designated 3, 4, (Fig. 3 The front or leading :end of the scoop is open, and the rear or trailing end-is a1so open, thusproviding a through open ended passageway,
The words front, rear, leading, and .trailingand words .of similar meaning are used with reference :to the normal movement of the device, in which the front" or leading end, is'theend'that leadsduring-snchmovement, while the rear and trailing-end is the opposite end.
The top and bottom 'walls are preferably similar in outline with their side edges along the side walls extending convergently from the leading marginal portions of the said top and bottom walls. Said leading marginal portions 5, 6 (Fig. 1) arepreferably :substantiallyhori- 'zontal and opposed, except that the leading marginal portion 6 of the bottom-wall is a blade adaptedto slide overthefloor of the poolalong its leading e dge,=:and.to slant slightly upwardly from such floor in a rearward direction from theleading edge thereof.
,The'rear' or trailing ends of the upper end lower walls preferably terminate in marginal portions 7, is having flanges 9 extending downwardlyfrom the side vedges of thetop wall 2, and flanges 10 extending upwardly ,,from theside edgesof the bottom wall 1. These flanges also extendalong the side edges'of the leading and trailing marginal portions of the top and bottomwalls.
The top and bottom walls 2, lrpreferablyextend diver gently relativevto each other in direction-from the from marginal portions 5, 6 toward the ;rear marginal sportions- 7 8 so'thatthe open rear end of the ,scoopiissubstantially greaterin vertical width'thanthe spacing :between the forward edges of thetop andxbottom Walls when the walls are at their minimum distance apart. The .spacingbetween the side walls ;at the rear :end of.the scoop is preferably no less than-the vertical spacing,:and it may-be greater if desired.
The maximum vertical width 'of'theflanges :at"the;for- Ward end of the: scoop is preferably substantially :equal'to the-minimum vertical spacing between the;for ward'marginal; portions, .which,-in a practical example, may-be; approximately twoinches, and the width of the flanges is -suflicient to insure their lapping at opposite .sides 'ofit-he scoop when the forward ends ofthetop andbottom-walls arernoved apart to their maximum "spacing, :as 'will be described.
The flanges 9, 10 atteach of the sides io'f-thescoopgare pivotally connected at their rear ends by horizontal coaxial pivots 12 (Fig.2) to permit the front er leading ends of thetop and bottom .walls to be spaced apart different distances. The flanges 9 are formed with arcuate slots :13 concentric'with said pivots .and through which bolts .14 carried by the flanges v10 extend. .A wing nut.15-.on
each .nut clamps the flanges together to .hold thetop and bottom walls spaced apart thedesireddistanee when the nuts 15 are tightened.
Therear end of the scoop is supported in elevatedposi .tionfor movement o'fthe scoop over the 'floor o'f a pool by means of wheels 16 on the ends of an axle 1'7'that,'in
turn, is secured to the bottom wall 1. The blade 6 at the leading end of the bottom wall will rest on the floor of the pool when the scoop is moved over the floor so as to enable, the blade to slide under leaves and other foreign material on said floor.
The inclination of the bottom wall 1 is relatively slight when the blade 6 is against the floor so that the forward movement of the scoop is suflicient to cause leaves and the like to readily slide over the bottom wall 1 and out of the rear end thereof.
The rear or trailing end of the scoop provides an outlet, the walls of which are the rear marginal portions 7, '8 of the top and bottom walls, and the parallel opposed rear end portions of flanges 9, 10. The top and bottom walls of the outlet may be formed with ridges 18 (Fig. 4) and the forward end of a horizontally elongated open work mesh bag 19 extends over the rear end of the scoop and past said ridges. Any suitable means may be provided for releasably, yet snugly, securing the forward end of bag '19 over the walls of the scoop outlet. One such means would be a relatively heavy elastic cord 20 around the mouth of the bag and carried by the bag.
The mesh openings of bag 19 are relatively large so as to permit water to pass therethrough with very little resistance, but sufficiently small to catch and to hold leaves, twigs etc. A bag 22 having smaller mesh openings is preferably over the rear end of bag 19, so that bag 22 will catch and hold much finer particles than will be held by bag 19. While the mesh openings in bag 22 are sufficiently small to catch and to hold some silt, it is not the intent that the present device remove the fine silt from the fioor of the pool. But it will remove the larger particles.
Both bags 19, 22 are preferably of buoyant material, hence will not scrape on the bottom of the pool in a manner that would tend to cause objectionable wear on their lower sides. They could, of course, be made of metal cloth, if desired, and in such instance would tend to hold their open shape.
Secured to the forward marginal portion of the top wall 2, at a point centrally between its ends is an elongated handle 24. The joint 25 connecting the handle with said marginal portion is a universal joint permitting swinging of the handle relative to the scoop in any direction. This joint may be a ball and socket joint or any other type of joint permitting universal pivotal movement of the handle relative to the scoop.
At each outer side of the forward end of the scoop is a vertically positioned, rearwardly extending plate 26, each plate being pivoted at its lower forward end to the scoop at the lower forward end of the latter. Coaxial pivots 27 so secure the plates 26 to the scoop for vertical swinging of the plates rearwardly of the pivots. Plates 26 preferably extend slightly divergently relative to each other in direction rearwardly of the pivots, and their lower edges are substantially straight so they will ride on the floor of the pool. The pivots permit the plates to accommodate themselves to irregularities in the surface contour of the pool, and they extend rearwardly from the pivots 27 a substantial distance to insure against leaves and the like along the sides of the path of travel of the scoop from swirling to positions behind the scoop and below the latter as the scoop is moved forwardly. Usually this distance is substantially less than the horizontal length of the scoop, but past the point where the bottom of the scoop leaves the floor when the wheels support the scoop on the floor with blade 6 against the floor.
In operation, when leaves or any other foreign material is observed on the floor of a filled pool, it is merely necessary to lower the scoop to the fioor and to scoop the leaves into the leading open end of the cleaner. If this operation were to disturb leaves alongside the path of travel of the scoop, the operator would be compelled to wait until the. leaves so disturbed were to again settle to the bottom before making the attempt to again scoop them up. Such a delay could well run into many minutes, and the advantages derived from the use of the cleaner would be lost. However, by reason of the plates 26, the leaves are not disturbed and the cleaner can be freely moved over the floor of the pool in any direction to eificiently pick up foreign solids.
The detailed description of the device is not intended to be restrictive of the invention, but it merely describes a preferred form thereof.
I claim:
