CHARLES W. COLLINS, or SEATTLE, WAsgrnoToN IOVAIQLE FLOOR FOR B ATHING-POOLS.

To Il w/Lom/ it may concern lle it( known that I, CHARLES W. COLLINS, a citizenfof the UnitedStates,- residing at Seattle, in thecounty of King and State of ll'ashingtolll, have invented certain new and useful Improvements in Movable Floors for Bathingflools'of which the following is' a specification. K

-1,he object of thisinvention is to provide swimming-tanks, bath"houses, or analogous places'ivith safety appliances in the'na-ture cfa Hooror platform 'which may be raised to' elevate drovvniiigpersons above the Water surface.

'llhe inyention consists in the novelconstruction andI adaptation ot devices', as will behereinafter described'and claimed.

The operation of the 'aforedes'eribed de" vices is as follows: Assuming the Weight or .'tank 12 to be inithe position in Whichit is" illustrated fulllinesin Eig. 1,v the lines 18 vand 2:2 il 3"areunconstralned with' re' .spectltovthe-patform 10 and the latterirests .mits lovverm'ost position, as lindicated"'by lfull hesnpn'the bottom of thepool, 4and vvith li'tli'e`ap'ron" 11 extended, "as shown. The tank is releasably held in such elevated posi! tion through the venpjagement `of the lugs 27 to 'the posit-ieri indicated by broken lines C,

Wherenponthe apronll Willoccupy the B ositin. `Mo're particulaily,as the tank sills, the lou'fer end of the plat-form `is irst horizontal position 'bvieason of the line '2 3 being primarily lno'pera'tively drawn through the .hole 25 of thebarll until the bar encounters the attachment ZU whereu )on all the lines become operative and the platform is thereafter raised in a"horizonti-l position. i

raiseduntil the platform is brought into a When it is desired to restore the platform to its original position, the valve 14 is olpened for the discharge ofthe water from t e tank 12, the weight of the platform then overcomes that of the tank-and the platform i sinks with a corresponding rise of the tank. The. tank lugs 27 are engaged by the hooked levers 29 and the tank refilled with water in preparation for future use. Should it be desired to employ the platform at a depth less than that .in which it is shown by full lines (Fig. l) the hooked levers 29 are withdrawn from the lugs 2T and after the tank falls sufficiently to present the hooks of arms J 28 tothe hooked levers, the same are engaged. The platform may advantageously be used at its lesser depth when the pool is being used by juveniles or beginners in the practice of swimming. From either of the desire -not to 'be restricted to the particu.

lax` arrangement of tank and y*line connections here shown, as it is evident that changes may be made in the appliances without departing from the spirit of the invention as set forth in the following claims. What I claim, is-

1.. In apparatus of the class describedfthe combination with a vertically movable platform, a water receptacle, hoisting connections between the platform and said receptacle, means to supply water to the recepftacle, a valve for the discharge of water from the receptacle, and means for releasably securing said receptacle in predeterf mined elevated positions. 2. In apparatus of the class described, a platform, a weight, means to releasably secure said weight in elevated position, and connections between said weight and the platform whereby the falling of the weight will cause one end of the platform t'o be primarily raised and subsequently raise the entire platform so that the same will project above the surface of the water. l 3. In apparatus of the class described, the

f combination of a vertically movable platform, a weight, hoisting lines for the platfermand connected with the weight, means -for releasablv securing said weight at various heights whereby thc platform may be supported at various depths within the water, and when the weight is released the latter will serve to raise the platform above .the water.

#11,. The combination with a swimming pool, of a movable floor section therefor noi'- nuilly inclineddownwardly, and WeightedV connections between the two ends o f the floor section and weight whereby when the weight is released and allowed to drop, the floor section will be primarily elevated to a horizontal position and then moved bodily upward.

5. A swimming poolfcomprising an clined bottom' provided for a portion of its length with a movable floor section resting thereon, a weight disposed at one end of the' pool, hoisting ropes connected at one end to ,the lower end of the floor section and having the opposite ends passing through said weight and securedat the bottom thereof, a second set of hoisting,- ropes connected at one end to the upper end of the floor 'section and terminating in a single line which freely passes through said weight and normally extends a distance below the saine, said weicht when lowered a refletermined disf tance adapted to elevate t ie lower end of the floor section to horizontal'positon and upon partially lowered to cause the platform to assume a horizontal position and'when Coinpletely lowered to elevate the platform above the water level.

'7.,The combination With a Swimming pool having a movable Hoor section, of moans for controlling the movement tliereof comprising a vertically 'movable weight, spaced `lugs carried by said 'weiglit,j and hook levcrsmounted on stationary su ports adapted to selectively engage Isai lugs whereby the elevation of the movable Hoor section is controlled.

S. An apparat-us of the class described comprising` a movable platform, a Weight having a rope,connection therewith, said eight consisting of a tank having a centrally-disposed well compartment through which the rope connectionl passes, and means carried by one end of the rope to engage the lower end of the weight to cause the platform to be elevated when said weight is lowered.
