VENTILATING SHADE-ROLLER. V

To all whom it may concern 1 i r Be it known that I, HARRYT. S'rAaTs, a citizen of the United States, andresidmg at vTownsend, in the county of New Castle and State of Delaware, have invented. certain new and useful Improvements in Ventilating Shade-Rollers, of which the following;

is a specification. 1 i g Thlsinvention relates to new anduseful improvements in shade rollers and more particularly to that class'adapted to be used for,v ventilating purposes. I An object of this invention is the prov sion of a shade roller for, ventilating purposes that will eliminate the useof brackets,

- rods, and all fixtures now used in combination with the ordinary shade roller to produce a means whereby ventilation may be produced by, lowering the uppersash of a w ndow and also lowering the shade roller I to the same height, therebyflpermitting ventilation above both. 7

.Astill further objectlof this lnvention is i thefprovision of a shade roller for ventilating purposes, whereby the upper sash of a window may be loweredand theentire shade and roller lowered likewise, and at the'same time permitting the shade to be operated upon the roller therefrom.

, \Vith the above 'and other objects in wow,

, this invention resides in the novel features of 'construotlon, formation, combinations,

and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which: Figure 1, 1s a front elevatlon of a window with my ventilating shade rollerrapplied roller with; shade removed, Fig. 3,,is' a per-1- spective of the guide arm, and operatingv lever, Fig. 4c, .is a longitudinal sectional thereto, Fig. 2, is a front elevation of my View ofmyfroller, Fig- 5, is a top plan view of the main shaft, with tubularxcasing therep on, Fig. 6, is a top plan fragmentary view I of :a portion of my roller with parts broken I away, F ig. 7, is a side elevation ofthe cap- 7 ping plug, with platethereon and Fig. '8,

1s a. front elevation'of the same.

Referring to ;the accompanying drawings, bysimilar characters of reference, the numeral 10 denotes in general my ventilating shade roller, which comprises the customary roller 11 to which the shade 12 is applied.

' This roller 11 consists of the customary hollow casing; end 12 and solid end 13, the lat- =yter end having a longitudinal recess ,14,

formed vtherethrough, of greater diameter being produced .to permit the said shaft to freely rotate therein,.without contacting with theinner face of the recess, while the.

outer end of this solid portion 13 has a crimped cap A mounted thereon, and which holds substantially in position a metal plate C, having a suitable aperture formed therein for the reception of the main shaft 15, thereby producing a bearing for the same and by means of which the shaft is pre-.

vented from contacting withthe previously mentioned inner face of the recess It This shaft 15 runs longitudinally through the casing 17 of suitable length to conform withthan the'diameter of the main shaft 15, this that of the coil spring 18, mounted thereon, 1

one end of which is secured thereto as at 19,

while the opposite end of the same is. se- 5 cured to the tapering end 20 of a capping plug 21 and secured thereto as at 22. This capping plug 21 being tapered at one, end to,

conform vwith'that of thethicknessof the tubular casing 17 mounted upon the main shaft 15, thus snugly contacting with. the

same as at 23, while the opposite end of this plug has a metal plate B secured thereto which is larger in diameter than the body portion of the cappingplug 21, thus prewidth so as to neatly cap the outer end of the hollow casing end l2jasat25, whilethe bodyportion of this plug 21is of a suitable ducing a 'flange 24c ther'eonof a suitable.

length and thickness as designated, by "the numeral 26 so as toextend for :a limited dis-l tance into the hollow casingv 12 and fit snugly therein, the samebeing securely held therein by means of screws 26; thus it will be readily seen that this plug is-stationary inthe casing, 12, and cooperates with the roller 11, both being rotatable uponthe main shaft 15, but the movement ofboth being limited as desired by dogs27 and 28,-secured to the outer face of the metal plate B of the capping plug 21. Thiscapping plug 21' also, has a longitudinal recessform'ed therethrough for the reception of the main shaft 15 and of greater diameter than the end 13 previously mentioned, while the 'metal' mounted thereon at oneof the extended ends same, this being produced for the same pur r pose as that of the recess formed in the solid.

plate B is secured to the 'cappingfplug'21 by any suitable means and has formed therein a suitable aperture to produce another hearing for the'main' shaft 15, whichalso pre- 7 vents the same fromcontacting with the inner face of the recess formed in the said plu'g,.thus producing a bearing for the saidshaft at each end of the roller 11. r Rotatable upon the main shaft an thereof is a sleeve 29, having a guidearm' 3O extending-upwardly therefrom and termih nating into an outwardly extending: arm 31,"

V 7 having an enlarged portion 32 formed thereon with a longitudinal slot 33 formed there.-

in,through which passes a cord 34 to be later describedr 'lhissleeve 29 has notches 35 and 36 formed therein, the notch 35, being notched in an oppositedirection to that of the notch 36, this notch cooperating'with the dogs 27 and 28, mounted upon theface' of the 7 metal plate B of capping plug'21,. whilethe opposite notch 36 cooperates with the dogs 37 and 38, mounted upon the inner face of a -""s pool 39; thus itwill be readily'understood that the first mentioned dogs. 27 and 28 oper-'-" ate in the opposite direction -to'that oftha I last :inentioned-i dogs '37 rand-38. I This spool 3.9 is mounted upon "the extended end of the 'main shaft 15 in advance 'of'the sleeve 29,

andsubstantially secured thereto by means of a set screw 40, while mounted at theop-fl posite' end of the main shaft '15 andqin ad- Vance of the solid end 13' and ca-p A of'th'e V roller 11' is another spool41 'also1substantially mounted upon the extendedjend of the main shaft 15 and secured theretoby means of another set'screw 42. The, spool 39 has a,

flange 13 extending-outwardly from the in ner face thereof thereby producinga cup same movement with the dogs 27 and 2 8-by like inner face, this flange 43'having'a tendmay to limit the backwardmovement of the dogs 37 and 38 operating therein, while the means of V a band 44 'whichfencirclesthe hollow casing end 12 andextends sjlightlyin advance of the cappingplug 21 as at This band'is of a double thickness at th s point,- beingicrimped to further assist in securely holding the capping plug 21 in position.

' JThe spools; 39 and 11 are for the recep tion of cords 34 and 3 1, bothof whichhave one end secured thereto by suitable means, while the opposite ends extend upwardly from the spools and arejsec'ured' to the win dow frame byscrew eyestdor the like, thus it will be seen that the saidscrew eyes are the only fixtures needed with which to apply my shade roller to a windowframe; The cord '34 extending upwardly 'from'the spool 39 passes through the slot 33 formed in the out wardly extended arma3l of thje guide arm 30-,

When it is desired to 'have the roller-re turned'to itsrespective position atthetop of the window, upon releasing the ,dogragain,

the roller iwinds backto its respective position, traveling upon the cords '34: and-3&1, this movement being" caused by the tension, of the'coil spring, cooperating with the main shaft 15, this shaft having the spools upon l which the cords 3 4 and 3tfy 'wind thereon, V and thesaid' spools being-substantially se l 1 i cured thereto by set screws Thus 'itwill be clearly; understood "that this roller iiwill operate *and travel {up and down the cords 34 and 341; in the vsame manner that the-ordi andhave wound thereonfasuitable' amount of cord or the like, of suitable strength-to 1' i permit the operationlof my roller for ve ntila-tinga windowof anylength and the 801 5 operation of my roller will now and-here p ently, the operator 'uponpulling the cord 48,

e Operation in raising and lowering the= roller independently does not interfere? in any way with the shade operating upon the 1 roller, as the' same'may be operatedin the i customary manner therefrom -by m'eans of the'idogs 27 and '28,: cooperating withfthe i notch 35 in the sleeve 29"togetherv with the .v coil springalso having tension on the roller 11 pr p r, owing to the factithat one'endof g' thesaid spring is secured to the capping plug, which is substantially mounted within:

the said roller and secured thereto, thus 'prof;

while the roller does not rotate upon the 1 shaft until the shade is to be'operated, then ducing the same function as that produced by the ordinary shade roller; now on the market.

It is to be remembered thatthe spools 39 and fl both being substantially mounted on the main shaft, will rotate with the same, the main shaft rotating within the roller 11,

the roller rotates upon 'the'shaft andoperatesv independently therefrom. r 1

It is now thought-that the; above description together with the accompanying drawings should readily give those familiar with this art, a clear explanation as to the operation of this roller, and it should be understood in this connection that various minor changes in the details of construction can be resorted to Within the scope of the appended claims, without departing from or sacrificing any of the advantages of this in-' vention.

' .From the foregoing disclosure taken in connection with the accompanying. drawings, it will bemanifest'that a ventilating shade roller is provided, which will fulfil all of the necessary requirements of such a roller.
