The. prime object-of the invention, there- 'fore, is to produce a simple, strong,durable,

and efficient construction which willuposi tively lock the bracket against slippage as distinguished from the ordinary frictional. lock now customarily depended upon to hold the brackets in proper relation.

, Another object of the invention is to produce a lock which is not limited in'its operation to predetermined .settings of, the bracket as is true with certain types of ratchet-toothed or notched constructions sometimes used for thus purpose.

A further object of the'winvention'is to produce a locker fastening device ofthe character mentioned which may be used on window brackets or plates, to which the perforations as shown at 6, and instead of "having their-opposite facesparallel as com-V mon in the art, have their outer faces tapered downwardly in opposite directions fromthe hanger brackets aresecured, where the window has no suitable transom bar or other sup port, to whichthe lateral arm awningmay be secured. 7 p a i With the generalobjects named inview and others as will hereinafter appear, the invention consistsin certain novel and useful features of construction and organization of parts," as hereinafter described and claimed; and in order that it may be fully understood, reference is to be had to the accompanying drawings, in which away, and illustrates a construction adapted for securement. to a transom bar or other part of the front of a building.

Figure 8 is a bottom plan view ofthe wedge shown in Figures 6 and 7. 1

In the said drawings, where like reference characters identify correspondingparts in all of thefigures, referring first to the construction shown in Figures 1 to 3 and 6 to SI inclusive, 1 represents a transom bar or the front of a building on which a bracket member '2'is pivotally mounted by means of a bolt 3, whereby the bracket may be oscillated around the pivot bolt to any desired angular relationship." The bracketQ is formed at P its lower end and on opposite sides of its center web, with outstanding ears 4 perforated for engagement with clamping bolts 5 threaded into the transom bar or building The ears i are slotted or'have elongated center web 7 outwardly to the ends of the ears 4 asshown at Sin Figures 1 to 3 inclusive, the edges of said wedge surfaces 8 being strengthened or or flanges 9.

Cooperating wedges for contact with the wedges 8 bear afix ed relation to'the buildstiffened by marginalbeads ing front or transom bar asthey' are perforated as at 10 and are carried by the bolts 5. These wedges comprlse inclined or wedge surfaces l1,and are reverselypositioned as regards'the wedges 8, so that the wedges when in operative position are respectively positioned with the thick and thin'partsin cooperative relation. Thewedge surfaces 11 are received between the beads 9 of the ears l, and on the under or lower sides are formed with guide or thickened portions 12 received within the slots 6 in said ears 4.

With a construction such as described, it will be evident that by loosening the bolts 3 and 5 to the desired degree, or by hammering or tapping the lower corner of the bracket 2, provided the wedge restraining such movement has been previously loosened, the bracket 2 can be set to the desired angle around its pivot 3, and then by screwing home the bolts 5, the later the bolt 3, the wedges 8 and 11, being in reversed relationship, thick portion to thin portion respectively, are engaged and provide positive fixed abutments to prevent movement of the bracket in either direction, it being evident that the bracket cannot lose its adjustment due to wind vibration or the like, unless turning movement is imparted to the bolts 5 to back them out of their threaded sockets. It will be evident also that the adjustment of the bracket is infinite in that it is not restrained to predetermined positions as with ratchet teeth or the like, and that it is absolutely positive, as above pointed out, as distinguished from a mere frictional clamp engagement between the bolts 5 and the bracket ears 4.

In Figures 4 and 5, 12a illustrates a corner plate for securement to a window frame by engagement of bolts in openings 13, when there is no transom bar or other suitable support for the reception of a hanger bracket 1 corresponding to bracket 2. In this construction the plate 12a is reversible so that it may be used in either the right or left-hand upper corners of afwindow. The plate 12a is formed on its opposite sides with pairs of reversed wedges 1 1 and in said wedge surfaces is provided with tapped openings 15 for the reception of cap screws or clamping bolts 16.

Adapted to be pivotally secured to the plate 12a is a hanger bracket 17 corresponding to the bracket 2 above-described, except that it is reversely mounted in that its pivbearing a fixed relation to said support, a

otal point is on a bolt or cap screw 18 engag 7 ing a tapped opening in the plate 12a, and

at its upper end it is formed with a pair of outwardly extending ears or portions 19 corresponding to the ears 4 of bracket 2. The cars 19 on their bottom or rear sides are formed with oppositely tapered wedge surfaces 20, the thinner portions of the wedge surfaces coinciding with the outer edges of the ears 19, said wedges being of substantially the same area and being adapted for cooperative relation with the reversed wedge surfaces 14 formed on the opposite sides of the plate 12a. The wedges 20 are formed with elongated slots 21, through which the clamping bolts, 16 project. It willbe evident that in this construction, the bracket 17 may be oscillated to any desired position of adjustment and then locked by screwing home the bolts or cap screws 16 in a manner identical with that of the construction first above-described, and that the result will constitute a positive look as in said first construction since reversed wedges are in cooperative relation, the left hand wedges and the right hand wedges, respectively resisting right and left movements of the bracket. It is to be pointed out that the opposite sides of the plate 1211 are duplicates, that is the openings extend clear through the plates, and the wedges, etc., coincide on the opposite faces of the plates, so that either face of the plate may be exposed and used, according to whether it is fastened to the right or left upper corner of a window frame. In this construction washers 22 are preferably interposed between the heads of the cap screws and the bracket.

It is believed the construction and mode.

of operation of the wedge lock has been sufficiently described and that recapitulation is unnecessary; and it is to be understood that while I have described and claimed the preferred embodiment of the invention, I reserve the right to make all changes within the spirit of the invention and without the ambit of the prior art.

I claim 1. The combination of a support, reversely port, a hanger movable on the support and;

formed with reversed wedge surfaces for cooperative relation with the first-named wedge surfaces, and means to hold said hanger with its wedge surfaces in engagement with the first-named wedge surfaces.

3. The combination of a support, a wedge hanger movable on said support and having a wedge surface reversely arranged with regard to and adapted to contact with the firstnamed wedge, means to maintain said wedges in contact to prevent movement of the banger in one direction, and mechanism to prevent movement of the hanger in the other direction.

4. The combination of a support, reversely disposed perforated wedges in fixed relation to the support, a hanger pivoted to the support and provided with slotted reversed wedge surfaces, the wedges and slots of the hanger being adapted respectively for cooperating with the wedges and perforations of the first-named wedges, and clamping bolts extending through said slots and perforations and clamping the parts together.

6. The combination of a support, reversely disposed perforated wedges in fixed relation to the support, a hanger movableon the support and provided with reversed slotted wedgesurfaces, the wedges and slots of the hangerbeing respectively adapted for cooperation with the first-named wedges and slots,

and clamping bolts extending the slots and perforations.

7. A plate for supporting window awnings and having a pair of reversely arranged wedge surfaces, a hanger pivotally secured to said plate and beingformed with a pair of reversely, arranged wedge surfaces for cooperative engagement with the corresponding surfaces of'the plate, and means for clamping said wedge surfaces to prevent movement of the hanger in either direction.

8. A plate for supporting window awnings and having a pair of reversely arranged perforated wedge surfaces, a bracket hanger V pivotally secured to said plate and being formed with a pair of slotted reversely arranged wedge surfaces for cooperative ens gagement with the corresponding POIlSlOIlS of the plate, and clamping bolts extending through the slots in the hanger and having threaded engagement with the perforations in the plate.

In testimony whereof I affix my signature.
