Another object-of this invention is to provide'an inseparable combination head rod'and pulleys J fixture having a locking mechanism which can secure anaw-ning head rod inposition without in any way cutting ing the awning fabric.

Another' obj 'of-this invention is to provide an insepara'lz le combination-"head rod or damagzsand pulleys fixture having aio'cking mechanismto secure an awning head rod in position and whichc'an' be'used for wooden head rods as well as for iron head rods, the locking mechanism serving merely to' hold the head rod iinjposition and does notexert any'clamping or "cutting actionon 'the rod or on the awning fabric.

"With these and other objects in view the invention will be hereinafter more particu- 3 larly descri-bedmnd thejconibination and ar-' rangement of parts will be shown in'the accompanying drawings and pointedout in the claim which forms part of this specification. it being understood that "various "40 changes in -the eform, proportion,'-size and minordetails of construction within the scope of the claim, may be 'resortedto g parting from the spirit or sacrificing any of the advantages' ofthe invention;

In the simplest forms of awning installations it is common practice to secure an {awn ing to abuilding'by means of screw eyes scre' vved into the window frame and passing through grommets inserted at equally spaced distancesalong the 'top edge of the awning. Figu'r'eB is a side view of a combination 100 several views, in which position. At the bottom of the head rod holder anetwo downwardly extending'arms I havingenlargem'ents at their lower ends upon which'pulley blocksmay be cast.

Thismethod requires five screw eyes and as many holes .in the window frame and is objected to becauseit results in the destruction of the framework. In the-modern installations, the awning fabric at thetop edge of the;:awning is wrapped around a metal or woodenhead rod and is secured thereto. Only two head rod holders are necessary and this avoids the necessity of making too many holes, and itis thismethod of installationzathat the present invention aims to improve. To install a window awning it is presently necessary to first, fasten a screw eye into the upper window sill; second, to hang a head rodholder on the screw eye; and third, tor

:hang one or two pulley blocks on the head rodhol'der. i must be mountedand demounted each year, these loosely.assembled'awning mounting devi'ce'scause constant annoyance by being inis-M placed and hardto handle and do not fully meet-the demand of the building industry for awning mounting hardware by means of which an aw-nmg may be quickly'andeasily' mounted and demounted without any danger 3 torthe mechanic or damagetothe awning fabric.

This invention provides an inseparable icombination head rod and pulleys fixture for awnings which takes the place of the three '1' or four separate and loosely assembled pieces.

Referencewill now be had to the drawings, wherein like numerals ofireference des-' :ignate corresponding parts throughout the Figure l is a perspective view of a head rod holder made in accordance with the subjectmatter of this invention and shows an awning head rod locked therein in operating Figure '2 isa front view of an assembled downwardly extending arms.

Inasmuch as window awnings head rod and pulleys fixture showing an awning head rod and part of the awning fabric in place.

Fi ure 4 is a front view of a head rod holder assembly partly in section, the section being taken as on line ww in Figure 3, and showing only one centrally placed downwardly extending arm from the head rod holder.

Figure 5 is a sectional view of this head rod holder assembly, the section being taken member in an open position.

As shown in Figure 1, there has been provided a bracket 1, having thereon two right angularly disposed pivot arms 2, 2, and a right angularly disposed seat 3. The pivot arms are provided with holes for. a pivot 4, which extends on each'side of the pivot arms a suflicient distance to enable a locking member 5, to be mounted thereon. A fragmentary section of an awning head rod 6, is shown resting on the supporting seat 3, and locked in position by the locking member 5, which encircles part of the circumference of the head rod. Two circular arms 7 and 8 integral with the bracket extend downwardly from the bracket, and these arms have enlargements at their lower ends. The en largements 9 and 10 are shown as semi-spherical, but may be semi-spherical, ball-shaped or disk-like, the object of the enlargements being to cast pulley blocks directly upon and in swivelling junction with them.

As shown in Figure 2, one single pulley block 11, and one double pulley block 12, have been cast directly upon the enlargements 9 and 10, at the ends of the arms 7 and 8, and are inseparably joined thereto. The pulley blocks can swivel around so as to face any direction from which the pulley rope may come, but under no circumstances can the pullev blocks be removed from the combination fixture without first breaking the metal of which the pulley block is cast.

As shown in Figure 3, the awning fabric 16 is wrapped around the headrod 6, and is secured thereto. 7 f

As shown in Figure 4, the lower end or the head rod holder bracket 1 is provided with a centrally placed downwardly extending arm 14, having an enlarged ball-shaped lower end 15, around which a pulley block may be cast in swivelling junction therewith. There has also been provided two countersunk are used for fastening the bracket'to the upper sill 18 of a window frame 19, the method of fastening being'vbest shown in Figure 3. Another hole 20 is provided at the center line of the bracket, and this hole serves as an auX- iliary in cases where the 'fixturemust be mounted upon a hook. The pivot l 'maybea copper rivet or a piece of copper wire, copper being used so that it will not corrode,

As shown in Figure 5, the locking member 5 is in an open position and the lock aperture 13 is free to receive a head rod.

It is to be noted that Figure 1 illustrates a head rod holder assembly, while Figure 2 illustrates a combination head rod holder and pulleys fixture. Two of these combination fixtures are mounted in a suitable posi tion on the upper window sill about six inches from each end of the window frame. The

'locki'ngmember 5 is rotated to the open posias on line g y in Figure 4, with the locking H tion shown in Figure 5, and the upper end of the awning containing the head rod 6 is thenmoved upwardly so that the head rod enters the lock aperture 13, and the locking memberis then rotated away from the window to the locked position shown in Figure 3. When this operation has been repeated at both fixtures, the upper end of the awning is mounted in place and will remain there in'one fixed position unless demounted by a mechanic. 7

To demount the awning the head rod 6 is pushed to the rear of the lock aperture 13, the locking member 5 is grapsed and rotated to the open position shown in Figure 5 leaving a clear opening for the awning to move away from the window. It is to be noted that the locking member does not exert any clamping act-ion. on the head rod, but merely encircles part or" its circumference and holds the head rod in position on the supporting seat.

The usual practice in the construction of pulley blocks for awnings is to cast the pulley block upon the arm of an eye member having a ball-shaped head around which the pulley block swivels, the eye serving to hang the pulley block loosely upon any kind of a hook. The present invention avoids the use of the swivelling eye member, the pulley blocks be-; ing cast directly upon the enlargements at the ends of arms extending downwardly from the head rod holder. 7

It is to be noted that the pivot at may be driven a tight fit into the holes of the pivot arms ,2, 2, and that the locking member 5 is free to rot-ate about the pivot,'-and that the pivot may be riveted or hammered over slightly at the ends.

It is thus seen that there has been provided a combination head rod and pulleys fixture for awnings in which the component parts are inseparably united as a unit, and which permits an awning to be quickly and easily 7 mounted and demounted, a combination head, holes 17, 17, in thebracket 1, and these holes rod. and pulleys rfi-xture having a locking mechanismwhich will notdamage the head rod or the awning fabric, and which presents a self-containedandfinished appearance and the cost of which is within the limits of commercial requirements.

.Having thus described my'invention, I

. claimas new and desireto secure by Letters Patent V In a combination rod and pulleys fixture for awnings, comprising a bracket casting for supporting a head rod, one or more downwardly extending arms having an enlargement at their lower ends, said arms being cast integral with the bracket, and oneor more pulley blocks cast directly upon the enlarged ends of the arm or arms and form an integral awning head rod and pulleys combination fixture in which the pulley blocks are inseparable from and in swivelling junction with the head rod holder bracket; substantially as described.
