9 Claims.

This invention relates to improvements in'drying tables which are commonly equipped with a plurality of heated forms for shaping, setting and drying hosiery and other like articles, and it'spurpose is to provide improved apparatus comprising means for ventilating and cooling the apparatus and the'surrounding atmosphere during the drying operation.

In drying tables as heretofore constructed it has been usual to provide long containers or pans extending along opposite sides of the assembly for containing the wet articles and the drying forms have been mounted in one or more longitudinal rows located between the pans and preferably at a higher level, the operators occupying positions on the outer sides of the pans whereby they were enabled to remove the Wetv articles.

from the pans and place them on the forms. The drying forms are commonly heated by steam or electricity to very high temperatures, for example, 250 Fahrenheit or more, and the heat arising from these forms and from the supply pipes leading thereto has caused high air temperatures in the region of the apparatus, with the result that the work of the operators has been very difiicult and uncomfortable particularly during warm weather.

The principal object of the present invention is to overcome the above mentioned difiiculties by providing an improved drying table having means for reducing the atmospheric temperature in the regions occupied by the operators. A further object is to provide a drying table in combination with means for causing a circulation of air or other medium adapted to maintain a comfortable atmospheric condition in the region of the table. Another object of the invention is to provide a drying table having a plurality of heated drying forms and comprising means for causing currents of air to be projected from one or more sides of the table'toward the oper ators, preferably in a, plurality of zones at different heights. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specification taken with the accompanying drawings in which one embodiment is illustrated. In the drawings,

Figure 1 shows a side elevation of the improved drying table with parts thereof broken away;

Fig. 2 shows an end elevation of the drying table, looking toward the right as viewed in Fig. 1;

Fig. 3 shows a vertical sectional view taken on the line 3-3 of Fig. 1; 1 i

Fig. 4 shows an end elevation of the drying table, looking toward the left as viewed in Fig. 1;

Fig. 5 shows a top plan view of the steam traps and associated pipe connections which are illustrated in the lower part of Fig. 4;

Fig. 6 shows a top plan view of the connections for supplying live steam to the drying forms and for removing exhaust steam therefrom, parts thereof being broken away; and

Fig. '7 shows a partial side elevation of theconnections illustrated in Fig. 6 with a portion thereof illustrated in vertical section.

As illustrated in the drawings, the invention comprises a'pair of long pans or containers ll),

of rectangular vertical cross section, which are mounted on opposite sides of the apparatus and are supported on cross frame members ll of angle bar form secured upon the upper ends ofvertical legs l2 having their lower ends secured by setscrews IS in enlarged fittings M which rest upon the floor or other support l5.

The pans H] are spaced apart, as shown par-' ticularly in Figs. 3 and 4, forming an intervening space l6 above which there is mounted a housing ll adapted to contain the conduits for sup plying steam to the drying forms l8 which are mounted in two rows extending above and longiof the housing I1, and also through the sleeves and'the top flanges of the frame members I I, be

ing engaged at their lower ends by washers 2 2' and nuts 23.

The means located inthe housing IT for supplying steam to the drying forms I 8 and withdrawing the exhaust steam therefrom comprises two longitudinal parallel units 25 each including an inner conduit 26 located within and spaced from an outer conduit 21.

21 are secured upon the cross bars 2| located in the housing I! and each outer conduit has se-i cured thereto by a series of studs 28 and nuts 29 the !base flanges l8 of the drying forms IS SO that both the outer conduits 21 and the drying forms are rigidly supported and held in station-' ary position with respect to the housing IT. The

drying forms l8 may be of any desired form'but The outer conduits are illustrated as being constructed in accordance with the invention described and claimed in the application of Arthur S. Mann, Serial No. 544,181, filed July 10, 1944. now Patent No. 2,433,470. Each drying form i8 is hollow and has mounted therein a pipe 30 of substantial diameter which is enlarged at its lower end and which communicates through ports 21* with the annular chamber of the conduit 27 around the inner conduit 28 of that unit. The inner conduit 26 has connected thereto a small pipe. 3! which extends through one of the apertures 21 and through the pipe 39 so that live steam may be conveyed therethrough to the interior oi -the drying form, while the exhaust steam willbe re;-

turned through the annular space between the pipes 30 and 3| to the annular chamber ofthe conduit 21 around the conduit 26'. Each drying form illustrated in the drawings comprises a de.-

tachable toe portion l8; 2. foot portion l8", a

conveyed through the pipe 3| into the interior of the detachable toe portion w ofeach drying form sothat this portion of the formi directly heated andthe detachable toe portion may be interchanged with other toe portionsto adapt the'form to the drying of hosiery of different sizes, but this feature does not form a part of the present invention.

Thesteam for heating the drying forms I8 is supplied to the inner conduits 25 of theunits: 25: by steam supply pipes 33 which are located in the housing [1 between the units 25,. as shown particularly in Figs. 3 and 6, the space wi-thin'the housing around the units 25 and the pipes Sibeing occupied by a body of heat insulating material 34'. The supply pipes 33 extend through the housing I! from the right end thereof, as viewedin Fig. 1, and their left-hand extremities are: connected by elbows 35 with hollow fittings 36 which embrace and form fluid tig-htconnections; with the adjacent ends of the conduits 26 and 21, as shown in Figs. 6 and 7, each fitting having an enlargedinner end to receive the extremity of the outer conduit 21 and a reducedouter end' which is fitted by the inner conduit 26. The live steam thus enters the-conduits, 26-

at the ends thereof which are'farthest. removed from-the source of supply and the steam 'then flows in these conduits 2.6 toward the right-hand end otthe apparatus, as viewed in Fig. 1, during which some steam is supplied to each of thedryingforms I8 connectedto each of the conduitsifi. As this operation goes on, the exhaust steam and condensate which flow downwardly through the pipes 30 of the drying forms =i.8-- pass into the: outer conduits 2T andare exhausted from the right thereof, as illustrated in Figs. 1, 6 and'l.

At'the. right hand of the apparatus, the portionoi the live steam in the conduits 25 which has not. been discharged into. the drying. forms and. the exhauststeam and condensate which. are contained within the outer conduits 21 are discharged through iittings 31 into. exhaust connections-includingpipes 38, connected byv elbows 3% to. the outer ends. of the fittings 31 and to.- the. ends of the conduits .26. for conveyin away the unused live steam, and pipes 413. connected directly to the fittings 3.!v for conveying awaythe exhaust steam and condensate from the discharge. ends. of theouter conduits 21.

The steam supply pipes 33 lead through apertures in the right-hand end wall of the housing I! and are connected by elbows 42 with transversely extending pipes 43, shown in Fig. 6, which are in turn connected by elbows 44 and pipes 45 with the casings of valves 45 having operating handles 146 which: maybe operated to; regulate the flow of steamthrough the valvesi rom a supply pipe 50, shown in Fig. 4, which is connected toeach of the valves 46 through the pipe connections The valves 46 control the flow of steamthrough the two units within the housing and the pressure of the steam may be controlled by suitable regulators connected in thesupply-line-for the purpose of regulating the temperature ofthe drying forms IS.

The verticallyextending exhaust pipes 38 and l'll'pass downwardly between the pans Ill at the right-hand end of the apparatus, as viewed in Fig. 1, and are connected to vertical pipes 52 througha. series of elbows 53 and pipes 54, as shown in Figs. 4, 6 and, '7. The vertical pipes 5-2 are thus arranged to extendparallel to each other at the right-hand end. of the apparatus andtheir lower extremities areconnected to strainers 55- having angularly disposed branch portion connected through. elbows '56. withthe drain cocks. 57. The body portions of the strainers 55,: are connected through pipes 58. and elbows lid-with the traps and the upper part of: each trap .is connected through a pipe 6! with. a. horizontal pipe 63, shown, in Fig, 5, through which the ex-. haust steam is, conveyed away tov suitable condensing apparatus or the like. By means of. this. system, the, exhaust. steam and. water are withdrawn from the, discharge ends of the-con.- duits126 and 21 which constitute the. heating units 25' located within thehousing ll.

As shown particularly in Figs. 2 and3, the housing I! is somewhat narnowerthan the; space,- 16 between the. pans'or containers i0 and its lower wall is depressed slightly below the level of the upper edges of the pans i0. thus providing; come.

paratively narrowerv longitudinal slots through which air be. discharged iromthe space-l5: for

the purpose of cooling the atmosphereand D D- which. are attached to'the lower portions of the side walls of the housing I1.

The. air under pressure which is discharged, through the slots- 85. is-supplied to these slots through the space Hi from an ain'chamber 61: formed Within a casing 68 of rectangular. cross section which. is secured to the inner sides of the.' legs [2. This. casing has side walls fi9rwhieh terminate at. their upper edgess-inzflang es-fiw arranged to seat against thebottom wallsofthe pans l0 and these side walls areprovidedat their lower edgeswith-inturneclflanges 69' which support the bottom wall l0. At points somewhat above the. bottom: wall 10, the .side Walls 69 are provided with oppositely disposed slots H which extend throughout the length of the housing 68 and which are bounded along their edges by the flanges 68 formed on the side walls of the casing. These slots are preferably located substantially at the. elevation of the knees. of the operator-softhat; air discharged therethrough Willi have; the desired coolingefiect in regions somewhat below the level of the pans l0. At its right-hand end, the catsing 68', which'is coextensive in length'withthe pans I0, i'siprovided with an end wall lz'through which extend the connections 54 leading t t P 1 6852. 1% i 1 5 :heating medium toksaid drying forms, arhousing At the left-hand end of the apparatus, as'viewed in Fig. 1, the casing 68 is connected to a fan casing15, of rectangular cross section, which communicates on its inner end with the chamber Bl of the casing 68 and which is closed on its upper fan 18 driven by an electric motor 19 which has its frame mounted upon supporting blocks 8D carried by the bottom wall of the fan casing, as shown in Fig; 2. Electric current is supplied to the mo tor '19 by conductors BI and certain of these con -i ductors are carried through the fan casing to'a controlling switch 82 operated by a push-button 82 which projects through the side wall of the fan casing, as illustrated in Figs. 1 and 2.

When the drying table is in use, the fan 18 is put in operation, thus drawing air through the screen 11 and projecting it under pressure through the chamber 61 from which a part of the air passes upwardly through the space l6 and is discharged through the slots 65 toward the upper portions of the bodies of the operators who are engaged in removing the wet hosiery :or other articles from the pans In and placing these articles upon the drying forms I8. At the same time, other portions of the air delivered under pressure to the chamber 61 are discharged through the longitudinal slots H in the region of the knees of the operators, thus eifectively dissipating the heat arising from the drying forms and the steam supply pipes leading thereto so that a comfortable room temperature may be maintained alongside the pans or containers I0, even in warm weather.

Although one form of the invention has 'been shown and described by way of illustration, it will be understood that it may be constructed in various other embodiments coming within the scope of the appended claims.
