RESPIRATOR.

Appncanbn' ined Aprn so, 192e. serial No. 105.652.

vWhile adapted for general use where the inhalation of s creened and purified air is a desideratum, my respiratory apparatus is designedespecially as protective means for the use of furriers and others handling and working on fur goods,tl1e object being, primarily, to insure the elimination of hair, dust, microbes, germs and vother possible contaminations of air p rior to inhalation. and, secondary, to purify the filtered air b y contact with charcoal which acts as a disin? fectant and as an absorbent of chemical impurities in the atmosphere involved, all as' hereinafter fully set forth; the invention consisting essentially in the specific construction, combination and arrangement of the component parts of the apparatus described and claimed, whereby the above named results and other incidental advan- 520 tages are attained. n

In the accompanying Adrawings ll illus'- trate a practical embodiment of the essential features of my invention in a respirator designed primarily for the use of furriers; although l do not limit myself to such use exclusively, nor ,to the identical construction and arrangement of component parts shown by way of exemplification, since changes may be made in minor details, and equivalent mechanical expedients resorted to, with like results, and without departing from the spirit and intent of my invention in this respect. i

l/Vith this understanding Fig. l may be designated as a perspective view illustrating the positioning of my res:l

pirator on the head of a user;

Fig. 2 isa perspective view of the nose guard and supporting band; Fig. 3 is a. perspective'view of the cranial suspender, filter' boxes, etc.;

Fig'.4 4 is abroad-side elevation, full size, of one of the perforate iilter boxes;

Fig. 5 is a narrow 'side elevation thereof; Fig. 6 is a section taken upon plane of v line 6?-6, Fig. 4;;5

Fig. 7 is a broadgside elevatioIn/of one of the lter boxes with the eoverffjj removed, with' the charcoal contents removedl in part;

box partitions. Y

The nose guard G, is formed of chamois leather or other suitable soft pliable ma# -size detailA in Figs. i to 8 inclusive.

Fig. 8 isa detail view of one offthe filter terial, and is provided with a stiii'ener y,

imbedded therein to straddle the bridge ot the nose of the wearer. The said nose guard Gr, is held on the head of the wearer by an elastic supporting band g', provided with an adjustive buckle g?, and with a pad g3, for the back of the heaththe side mem` bers of the band g, beinfr designed to rest on the ears kof the wearer thereof, as indicated in Fig. 1, of the drawings.

F, F, arethe filter boxes, shown in 'flll l O each of these boxes F, F, isl pivotally at; tached a yoke Y, having a medial suspender rod y, which is slidably supported in a frictional sleeve s, on one extremity of the cranial suspender S, designed to straddle the head ofthe wearer as illustrated in said Fig. l, of the drawings, the filter boxes F, F, being thus positioned against the cheeks of the wearer.

The filter boxes F, F, are connected with the nose guard Gr, below the nostril portions thereof by means of ducts D, each duct consisting of a medial pipe section d, provided with rubber coupling tubes d', d', by which it is attached to a filter nipple 7*', at one extremity and to a nose guard nipple y g4, at the other extremity.

Drain tubes dx, for the reception of condensed moisture resultant from exhalation, areconnected with the medial pipe sections of the ducts l), asy shown in Figs. l and 2, said drain tubes d", being provided with removable end closures as indicated.'

The outer' or base plate f, of each filter box F, is perforated, and is formed with aV central perforated cylindrical partition f2, for the inlet and outlet of air, the removable disc kpartition f3, being also perforated forl the same purpose. f4, is an imperforate back cover late for the retention of the charcoal filling o, within the compartment between it and the partition disc f3, as shown more particularly in Fig. 6, of the drawings. f5, is a reticulated screen 'which is inter osed between the charcoal 0, and the filter nipple f, as illustrated in Figs. 6 and 7, .of the drawings.

What ll claim as my invention and desire to secure by Letters Patent, is

A. respirator of the characterv designated rbehind the helixes 4,.

comprising a nose guard and elastic supporting head band provided With an adju'stive buckle and real` head pad, perforate lter boxes, ducts connecting said filter vboxes with said nose guard, drain tubes pendent' from said ducts, each ilter box being `formed with a central perforate tubular air inlet, with a perforate partition f andan imperrforate cover and containing a cranial suspender and means for adjust-A ablysupporting said lter boxes thereon,

substantially inthe manner and for 'the purpose set fort-h.
