It may be remarked here that iny practice -it is` desirable and. convenient to provide tliefitrenclr gutters withabottom` outlet at each-spaced interval of twenty. feet. By so doingtherewillv be ample drainage capacity Y totalrecare of, rapid and voluminous overflow;v From -an inspection 'of the drawings, itwill be readily understood that the barrier structure 30,;n0t only' serves as an outer'brim -for the water of the pool, but also serves'as means for directing the drainage fromv the Asurface of the inclined floor'37 into the outer trench gutter 34. As previously intimated, the trench gutters are Continuous about the pool. The bases of these gutters, however,

preferably do not have longitudinal-inclination, the drainage to the bottom outlets being ac'complishedby meansv of insert pieces or tiling e6 set or otherwise arranged so as to slope towardthe interval bottom outlets.l *Inthis connection, by referring to Fig. 13, wherein there is illustratedby way of eX- ample a swimming poolin plan, the reference characters L: indicate the low points ofthe trench gutter where'the'bottom outlets are located,l while the'reference Characters H indicatev thev high vpoints lin the Vgutter from which the water drains tothe low points and henc'eto the bottom outlets.

In carrying the invention into effect, as disclosed in Figs. 1 and 2., the opposing side Walls of each of the trench gutters 2S and 34 are providedwith shoulders 47 forming seats for vsuitable removable drainage cover units '48.'- Asillustratedin 5,'these drainage covers may be formed with inwardly sloping top vportions 4800 provided with apertures 48.7)

or,-iff=desired, they may be'produced withV in'\\'"aid`ly sloping port-ions 48a@ which direct the' water into a central elongated slot 4852).' From an inspection" of Fig. 1, it will befunderstood" 'that the removable perforated v f'lrainage"covers for the trench gutter 28con- V'stituteineflect a continuation of the sitting ledge Lportion 28 ofthe coping Aunits.1 This affords af highly convenient and sanitary form of: construction, since upon the removal of the drainage covers, the trench gutters Vcan be thoroughly cleanedA byv means of a mop .as Villustratedv 'at-49(Fig. 2)v or by means of a hose as {iO-which may be employed as means for cleaning* by the medium vof water or steam. Y* The drainage covers, when positioned in theirseats, manifestly cover-'over the trench gutters so thatfthe bathers cannot step or fall 'into the latter and thereby injure themselves. YAn important advantage'of' the' pool construction herein described resides in the'fact that.. since the Water level isat or close to the crestof the life rail 22, theba'thers may easily and-.readilygfrom a swimming position upon theA surfaceofthe, water, advance-onto the l fs'itting ledge, wlierethey may either sitor stand4 asf they desire- In Figs.A 3 and 4, there iis,shownfafmodified form of'construction in rthe floor, directs .thewater into the inner, trench gutter whose construction 1s substanfv tially the same asfthat shown-infF-igs. 1 and 2. wWith this construction the waterprooling is, arranged as inthe previous instance over the entire outer surface of the retaining wall 17. The construction of the coping units,'inner trench 28 and'removable perforated drainage covers 48, and as well the location ofthe bottom outlets for the trench gutter 2S, :are all the same'pas hereinbeforedescribed.' In Fig. 10, there isillustrateda construction substantiallysimilar to that shownin Figs. 1 and 2, exceptthat in this instance each bottom outlet for theouter trenchy gutter-16 is connected with,y the corresponding line. pipe 43 ,through which the'water flows fromthe inner trench gutter. rlfhere is disclosed a sieve containing outlet head orthimble ehavi'ng -a stemV passing through the base of the outer trench gutter and as well through the waterproofing forithreaded;connection with the' flanged fitting 56 whereby,as inthe instance previously described, theV waterproolin'g is compressedrso as to effect a water tight oint.

Associated With the fitting- 56 :is a pip-e joint having `connection with a suitableT-'piece 58 incorporated in thepipe line 43. By this arrangement, the water-collected in the outer `trench gutter is drained .into the same pipe line which carries olffthe water from the inner trench gutter 28. Y f Y In Figs, 1112, 15 and 1G, there is disclosed a'construction in which the inner trenclrgutg ter Yis made in the formlof a deep trench gutter '59 havingample,capacity*toy provide fora continuous inclinationY of the insert `members 1 1 .fand 12)'froml a high point as Hf at one. end of the pool toa single low point illustrated at L at the opposite end. of the pool. `Located at the low point L. is a spillwayoutllet structure`61` Fig; 12) which leads to piping Ycommunicating with the sewer. The construction of the coping course.'A of the barrier or outer brun. 52 and of the perforated removable drainage covers 48is substantially -An advantage of this :deep trench, construction is thatit avoids Ythe cost and expense vof theintervally spaced bottom outlets, the one spillway outlet VK61 lsuticing to carry otlv the entire overflowjwater .from the pool and as wellthedrainage water fromtlie surface of-,the floor.

facing and other parts', may be constructed vor prodiiced'out of concrete, or' out of any inaterial whatseever, irrespective of its nature or kind, whether tilingterra cotta., brick,

' concrete orinetal, usable or eapableof being used with advantageous results.v Y y `While several desirable and satisfactory? embodiments of the invention have been dis' closed herein, it will nevertheless be understood that the improved pool constructionis susceptible to still further modifications in the form, construction and relative arrangement of its several parts. Reservation, there fore, is made to the right and privilege ofl adopting all such'legitima'te changes as 'may be fairly embodied within the spirit scope of the invention as claimed.
