It is customary in practice where a metal beam or transom bar is secured in the frontof a building, to provide properly spaced openings therein for the securing bolts for the awning support, and it has been found that occasionally corresponding bolt holes in a hanger will not properly register with such holes in the beam or if they do it may be found that the hanger is not occupying an exactly vertical position. VJith the construction above described it will be apparent that the provision of large openings or horizontal bifurcations in and at opposite sides of the hanger will permit of a slight swinging adjustment of the latter and thus per mit the bolts to be utilized in clamping the hanger firmly in the position desired. The above arrangement however in order to guard against accidental swinging slippage of the hanger, possibly because of the bifurcations or elongated openings for the bolts 5, makes provision through the use of the bolt 7 and nuts 8, to anchor the hanger on one of the fixed bolts, against such lateral slippage, in a very simple and effective manner.

The cylindrical head of the hanger is provided with a horizontal transverse bore 9 which is of double conical form, that istapers inwardly from each end as at 9. The lower part of the head is attenuated as com-- pared with its upper part (see Figure 2)- so that the lower portion of the head, indicated at 10, shall be relatively narrow. he bracket is formed below the head and in the attenuated portion mentioned with a transverse opening 11 below the narrow portion 10 of the head, and back of said portion, the web is formed with a flanged opening 12.

A bolt 13 extends rearwardly and central- 1y through the attenuated portion of the hanger below the head thereof, through the opening 11 and into the opening 12, and within the latter-is engaged by a retaining nut or the like, and the bolt bears a journaled or swivelled relation to the hanger that when turned it shall have no end-wise movement, and threaded upon said bolt within the opening 11 is a collar or nut 1 provided at its opposite sides with cylindrical trunnions 15. I

Fitting snugly within the conical bore of the head at one side, is a conical clamping element 16 having a peripheral flange 17 bearing against tne opposing side of the head of the hanger. Said element is tubular and its inner bore is reversely tapered relative to its outer surface, the smaller end 18 of the bore being adapted to snugly accommodate a pivot clamping bolt hereinafter mentioned, and the inner end of the clamping element 16 is provided with diametrically opposite notches 19 and saidelement is provided with a depending lug 20 fitting partly in the opening 11 adjacent the narrow portion 10 of the head, and said lug is provided with an opening 21 in the horizontal plane of the bolt 13.

A clamping element 22 in opposition to clamping element 16 is of conical form and fits snugly in the opposite side of the head 2 and is provided with diametrically opposite tongues 23 engaging the notches 19 of element 16 to insure proper relation of said elements when applied to the hanger head, and said clamping element 22 is provided with a depending lug 24E slightly wider than the opening 11 so as to bear against the attenuated portion of the hanger head. The lug 24- has a projecting portion 25 to fit into the opening 11, and extending through said projecting portion is an opening 26 in alinement with the opening 21 of lug 20 of clamping element 16, said opening- 26 being adapted to receive the other trunnion of the collar or nut 14,. as shown clearly in Figure 1,, the arrangement being such that the turning of the, bolt 13 in one direction or the other shall efl'ect forward or rearward movement thereon of. the nut. or collar 14, as shown clearly in Figure 4, the arrangement being such that the turning of the bolt 13 in one direction or the other shall effect forward or rearward. movement thereon of the nut or collar 14: and thereby, through the trunnions of the latter, effect rotatable adjustment of the two clamping elements, and in this connection itv will be noted that the interlocking of the body portions of said clamping elements together through the engaging tongues 23 and notches 19, is primarily for the purpose of automatically alining the openings 21 and 26 for engagement by the trunnions of the nut or collar '14, and thus facilitate the operation of setting up the awning. The lug 2 1 is provided in its outer facev with arecess divided by a pair of central ribs or partitions 27 into a pair of similar chambers 28.

A U-shaped bracket 29 fits against one side of the hanger head and the corresponding end of the clamping element 22 and is provided with a conical boss 30 fitting snugly in and projecting through the clampingelement 22 and into the clamping element 16, and is also provided at its lower end with a plurality of radial ribs. 31, three being shown. The engagement of the middle and rearmost ribs 31 with the respective recesses 28' of lug 24; of clamping element 22. holds the U-shaped element in a certain position relative to said clamping element. If a different relative position'is desired, the said parts should be fittedtogether will the middle and front ribs 31 engaging said recesses 28. This arrangement is adapted. to set the arm, hereinafter identified, to dispose the awning at a greater pitch or inclination than the first named adjustment. It will thus be apparent'that the parts are adapted for use with all so-called lateral arm awnings, regardless of the extent of projection thereof beyond the building line.

The boss 30 of the U-shaped bracket is provided with a central bore enlarged at its outer end to form angular socket 32 to accommodate thehead of a horizontal pivot and clamping bolt 33 extending through said boss and the clamping 'menn ber 16, and mounted upon the threaded end of the bolt is a nut 34 bearing against exposed face of the clamping element or member 16 so as to clamp the same and the U-shaped frame firmly together, and thus relieve the adjusting bolt 13 of that duty after the parts have been disposed in their final working positions. It will'be apparent that quick and relatively wide adjustments are effected through the interlocking relation between the U-shaped bracket and the clamping member 22, and that the final fine adjustment necessary to insure the exact pitch of the awning desired, is effected through adjustment conjointly of the two clamping members or elements and the U-shaped bracket, and after such final adjustment is effected through'the operation of the bolt 13, the nut 34 is screwed home tightly so as to relieve the bolt '13 of unnecessary strain, as above stated.

The U-shaped bracket carries a substantially vertical pivot bolt 35 extending through the metal socket portion 36 of the lateral folding arm customarily employed in this type of awning support. The head of the pivot bolt 35 is provided with n. peripherally notched enlargement 37, and a dog or detent 38 is secured to the U-shaped bracket and adapted to engage one of the peripheral notches .of said enlargement, and at the same time overlap said enlargement so that the pivot bolt 35 may be retained in position without using any retaining as. vice at its lower end, such asa nut, cotter or the like. A spring for unfolding the folding arm is mounted on the pivot bolt and secured thereto at one end and at the other end bears against the arm. This construction is not disclosed in this application, as it is covered by one of my applications now pending, it being desirable to state however in this connection that the tension of the sprin can be varied by the turning of the pivot bolt, and held at the desired tension by engagement of the dog or detent with the notched periphery of the enlargement of the head of said pivot bolt. This feature is not detailed in this application, as it also forms a part of the application hereinbefore mentioned. Furthermore the particular mounting of the arm on the U-shaped bracket has nothing to do with the con- 1 struction whereby the U-shaped bracket is adjusted rotatably and secured at any desired point in such adjustment.

As the various adjust ients have been set forth in connection with the description of the construction oft-he device, it is not deemed necessary to recapitulate reference to the operation whereby the pitch ofthe arm may be varied or whereby the vertical position of the hanger shall be secured.

Figures 9 tol inclusive, illustrate a construction for securing the hanger in position, which in principle, corresponds to that appearing most clearly in Figure 3, except that through a wedge or cam action, the bolt which by adjustment laterally anchors the hanger against lateral shifting, and also serves to apply rearward clamping pressure on the hanger.

In sheet 2, the front face of the back wall of the hanger is provided with vertically spaced horizontal ribs 39, one above and the other below the respective bifurcation 4, and the front face of the backwall between said ribs tapers or slopes outwardly as at 40, and the web ofthe hanger is provided with a pair of openings ll, one above and the other below and at equaldistances from the horizontal plane of the center of the bifurcations. I

Fitting slidingly through the respective openings l1 are angle-bolts 7a corresponding to bolts 7, and said bolts pro ect inwardly respectively from the inner ends of perforated heads 8a fitting snugly upon the bolts 5. In this case, the bolt heads 8a taper inwardly to correspond with and flatly fit the tapered faces 40 of the hanger. In other words, the heads 8a constitute wedges between the tapered faces of the back wall of the hanger and the heads of bolts 5, so that inward adjustment of bolts 7w shall cause their respective heads to apply rearward clampingpressure on the hanger, it

being noted that the front faces of the heads 80 are parallel with the rear or untapered face of the back wall of the hanger and the rear sides of the heads of bolts 5, so that the full area of the heads of the lattercontact with and apply force flatly upon the heads 8d. The upper and lower edges of the heads 8a are parallel with and adjacent the opposing sides of the upper and lower ribs 39, so that the latter serve as guides for the heads 8a in their inward or outward sliding adjustments. The heads 8a also have elongated bosses 42 at their outer sides, slidably fitting the bifurcations these bosses giving the heads 8a a relatively extended contact on the bolts 5, and of course, increase the strength and rigidity to the heads. It will be noted, in this connection that by equipping one of the bolts 7a with nuts at both sides of thehanger web, as bolt 7 is equipped in Figure 3,the other bolt 76: may be dispensed with. It is preferred however to use the duplicate construction as illustrated on Sheet 2, using one bolt 8a, to effect adjustment oi the hanger in one direc tion and. the other to efiec reverse adjustment ot th hanger. li here two bolts 8a are employed, one is reversed relative to the other. It is therefore necessary, if the bolts 8e are of interchangeable construction, that the bolt shank shall be offset relative to the longitudinal of the head, shown. It will be seen that if the arm 36, when in folded position, sags or slopes downward toward its free end, it can be readily brought to a horizontal position by such adjustment of the bolt or bolts 80., as shall effect proper lateral swinging adjustment of the respective hanger. If a pair of the bolts 8a are employed, it will be necessary of course, to adjust both, one to effect the swinging movement and the other to permit or accommodate such adjustment.

From the above description, it will be apparent that I have produced a lateral arm awning support which embodies the features of advantage set forth as desirable in the statement of the object of the invention and which may obviously be modified in minor particulars w'thout departing from the principle of construction and mode of operation involved or from the spirit and scope of the appended claims.
