Specification of Letters Patent.

Patented Sept. 11, 191W.

Application filed December 19, 1916. Serial No. 137,897.

outer sash and locatedbelow the same and outwardly beyond the inner sash, in order to effectually prevent ingress and egress irrespective of the position of the lower sash allowing the latter to freely move to and from closed position.

The primary object of my present improvements is to provide a window guard which may be readily inserted in, and removed from, its operative position in order to provide for its use in selected windows of a series, and its change from one window to another, as desired.

A further object of my invention is to provide a guard, the several main guard bars of which may be effectively locked in operative position by the use of a single look, so as to necessitate the use of but a single key in securing the same in, and removing the same from, operative position.

A still further object of my invention is to provide a construction susceptible to considerable range of adjustment in adapting the same to spaces of varying widths and heights, and a still further object is to provide a strong and effective arrangement permitting of practically unlimited embellishment where beauty and design and artistic qualities are a consideration, above and be yond the normal strength and efliciency of the arrangement as a guard.

eferring now to the accompanying drawings illustrating my invention and forming a part of this specification, 1

Figure 1 is an elevation illustrating my improved guard in operative position.

Fig. 2 is an enlarged sectional view taken through the central portion of the guard substantially on the line 22 of Fig. 1;

Fig. 3 is a vertical transverse section taken substantially on line 3- of Fig. 1,

"Fig. 4 is a detail section through one of the socket fasteners and a portion of one of the guard bars.

Fig. 5 is an inside face view of one of the clamping plates.

Fig. 6 is a front elevation of the locking screw.

Fig. 7 is a side elevation thereof.

Referring'now to these figures, and particularly to Figs. 1, 3 and 4, my improved guard essentially comprises a plurality of radially extending guard bars 10, "each of which is threaded at 11 for some distance from its outer end, so as to adapt the same to screw within, and be adjusted with respect to, a tubular connecting member 12, the outer end of which member is permanently and pivotally connected by means of a rivet 13, or the like, to an angularly projecting stud piece 14 for engagement. within a socket fastening member 15.

As particularly seen in Figs. 1 and 4:, the socket fastening members 15 are secured in a series of equal number to the guard bars 10, at the upper and lower portions of the space in which the guard is to be erected, the two upper fastening members 15 being preferably secured. to the lower rail 16 of the upper sash, and the two lower fastening members being secured to the sill 17, all of the fastening members 15 being in the same vertical plane, and each having fastening screws 18 extending into the material of the parts to which it is connected and projecting through its inner wall only, so that the heads of the screws or fastening members 18 will be covered, as particularly seen in Fig. 4, when the respective stud piece 1 1 is introduced therein, so as to thereafter prevent unwarranted removal of the socket fasteners 15, while the guard bars 10 are in operative position as presently seen.

The inner ends of the several guard bars, clustered as they are at the center of the guard frame in operative position, are, in this position clasped by a pair of opposing clamping plates 19 and 20, each of which is provided with an inwardly projecting annular flange 21 around its outer edge, the flanges 21 having grooves 22 which when together, form channels for the reception of the inner ends ofthe bars 10, and there bein'g several such grooves adjacent the position of each bar in order that the incline;

tion of the several .bars 10 may be varied in with its outer end closed, and witlrits inner end provided with an internally threaded inwardly projecting flange 25 into which the externally threaded tubularbarrelw26 Off a clamping nut 27 is adapted-to screw, the nut bearing against the outer face on=the inner plate 19, as shown in Fig. 2.

The nut 27 is provided with a tubular barrel, in order to provide for the reception in this barrel of a lock generally designated at 28, of suitable type, having, for'instarice the radial bolts 29 adapted to:be'extended outwardly at points inwardly beyond the: flange 2 5 before mentioned; so as to pre vent the nut 27 from being turned tore leasethe: clamping plates-19 and 20 when the parts are in operative position. 7

It is thus obvious thatithe inner adjacent ends of the several radial guardbarslO are vclamped with sufiicient pressure to-prevent their rotation with-respect to the tubular, aduistingvmembers 12.before described, and that the means utilizedfor' the: purpose of clamping the bars 10 embody asingle lock requiringbut a single key for itsrelease in order thatthe'bars 10 may bereadily withdrawn from the window frameafter release of the clampingplates 19 and20, by withdrawing; the outer ends, carrying; the stud fasteners 14 from the socket fasteningmembers 15. a

It is further obvious that by the particw lar arrangement on ,the socket fastening members 15, as before described, thatiis the fastening of the upper twothereofto the lower rail of the upper sash,.thelattermay be either secured in closed position, or'in slightly lowered position providing. for-yen: tilgtion through the space above itsupper en I 7 It .is obvious that the spaces-between the several guard barslO may be filled inabya suitable framework, or I preferably utilize for this purpose the radially outstanding arms- 30, projecting outwardly between. the several bars 10, and to the outer-portionswof which are secured laterally spaced connect-u ing, rings 31, between which the bars 10 passso as to'wleave the latter free for: adjustment in the manner before described. The inner ends of the arms are preferably provided with reduced extensions 82,-engaged-lbetweerr the clamping plates 19. and 20in channels formedby recesses 33 and.the,flanges'- 21, similar to the recesses '22 before described; To the outer endsiof the arms=30.are also securedthe inner. portions of suitablescrolls 34, extending outwardly between" the rings 31 with their outer portions secured to the said rings 31 by clamps 35.

Itisobvious however, that the particular essentials-of the present invention being the use and means for this purpose including the radially projecting-1 guard bar's the: means by which the outer *endsithereofaare detachably held,, and the 'clainpinglconneetions betweentheir inner ends,,including the lock 28, through the combined userofall of which the: window guard isrendered practical, convenient, readily portable, andzefiectivenand efficient in use. i I
