'To all whom it may concern:

Be, it known that l, JULIUS JUDnLsoN, a citizen of the United States of- America, residing at New York city, New York, have invented certain new and useful improvements in Driers, of which the following is a specification.

The present invention relates to improvements in driers, and has especial reference to the class of driers constituted of one or more drier frames ,adapted to supportthe articles to be dried, said' drier frames being movable into and out of a containing casing.

The invention contemplates the improvement of existing driers in numerous structural details, certain of which will bepointed out in comparison with the existing stilte of the art'.

Une object of the invention, and perhaps the most important one, is to facilitate the vreciprocation of the drier framein its casing. Heretofore the means generally em- A played for such movement of the frames consisted of overhead pipes upon which rollers, secured to the drier frames, were de signed to revolve. These overhead lpipes are usually of considerable lengthand weight, and are anchored in the ceiling or some other :fairly substantial supporti They are unsightly, and 0W' to the considerable weight placed thereon they frequently bend or tearloose from their retainingsupport necessitating `frequent and expensive repairs. Moreover such overhead pipes occupy space which could, as a rule, be more advantageously employed forV other pur' poses. Attempts have been heretofore made to eliminate these overhead pipes by supply .ing the lower part of the front door of the drier -trame with rollers, but this method has been entirely abandoned as a failure. The nonsuecess of this method of construction is due partly to the fact that owing' to uneven iioors the drier frameswould not run true and would frequently catch in being drawn out. of or pushed baclr` into the casing, and partly to the fact that considerable heat was permitted 'to escape from the casing when 'one of the frames was drawn out.

7lscvercome the several lobjectionable teatures above pointed out, by providing a sim- Specieation of Letters Patent.

ple and eflicient drier frame suspension system, contained within the casing, whereby the drier frames may be smoothly and easily moved out of and into the casing, eliminating all overhead pipes, and causing the drier frame to run absolutely true. In general terms, the mechanism for accomplishingathis consists of suitable supporting means, such as upper and lower T-rails, upon which ball bearing rollers run, the latter being held and guided by flexible curved arms secured to the drierframes. In addition to these fea'- tures-I also prefer to provide upon the front ydoor of each drier frame a suitable ball bearing roller which is both vertically and horizontally adjustable,y whereby the roller may be so fixed as to allow for any unevenness or inequalities of the .floor and still run smoothly.

Another object of my invention` is to prevent the escape of heat iroln the interior oi the casing when one or more of the drier 'f1-anios are d 'awn out therefrom. A drier 'frameconsists oflafront and rear upright, door,` or section, several feet apart, carrying spaced clothes supporting and drying pipes, upon which the articles to be dried are suspended. As now constructed the front door is considerablyl wider than the rear door or section. due to the fact. that the frames Wabb'le" orfinterferewith each other when pushed 'in or out, and unless the rear sec tions lwere narrower than the front sections, the 'frames would catch when moved. As

u` result, when a frame is pulled out of the\.-

casingits entire length, the rear door or sectionr does not coverl ythe entire width which had been theretofore occupied or spanned by the front door and hence a very considenable quantity of heat is permitted'tofescnphy atv .both longitudinal edges of the rear door.

` According to my invention, both the front and rear doors of the frame are made precisely the same width, and I am enabled to do this because of the fact that, when einploying` the suspension system above referred to, the drier frames run absolutely true,

no one encroaching on, or interfering with,

the other, 'and `Jihen the ralnes are drawn only. or pushed 1n they run 1n a perfectly straight line, so that when a frame 1s drawn ont its entire length the rear door will extend the entire Width theretot'ore occupied b v the front door and completely prevent escape of heat troni the drier. It has also been eustoniary to provide a wooden guide bar at the front of the drier, which bar was perforated to receive and guide the lower most pipe in eaeh drier iframe. )wing to the high degree ot heat developed within the drier, these wooden bars were a source of danger from tire, and another object of niy invention is to eliminate the use of a har ot' 4this hind, the same becoming superfluous when luy suspension system iseniployed.

Other objects of my invention, and the details oi? construction thereot will become; ap )arent troni the following deseription by ar of the aeronipanying drawings, where inlignre l is a side elevational view ot a drier, having one side wall of the easing removed lo show the interior construction, one drier frame being partly drawn out et, and the other entirely within, the easing; Fig. 2 is a side elevational view, parts being shown in Section, of the flexible upperl arm and roller secured to the traine; Fig. il is a rear elevational view of the strurture shown in Fig. Fig. 4 is a side elevational view of the roller adapted /to be secured to the bottoni of the front, door or section; Fig. 5 is a horizontal sectional view on the line 5-5 oit' Fig. l; and Fig. 6 is a rear elevational view of Fig. Ll.

In the embodiment of the invention herein illustrated, lrdesignates a preferably rec; tangnlar casing having heating coils 2 beneath the saine, the lower wall 3 of the casing being construeted as a screen, the heat troni the Coils 2 passing upwardly therethrough and the drippings from the articles beingl dried falling through the saine.

Designed t0 be, contained within the casing, and to be reeiproeated relatively there to, are a plurality of drier `trames, eaeh of the stern of the T extending upwardly. Se;

eared near the upper party of each rear upright 5 is a comparatively short bitureated bar l0 (Figs. 2 and which supports a ball bearing roller 1l designed ,to run on the T rail 8. The roller ll. is mounted upon a spindle l2 which is engaged by the bifurcated iexible arin 13. jointed approximately at. its iniddle through tlieinediuni ol nut. and bolt` l-l and having its other end 'l5 suitably secured to one oi the drier pipes tl.
