AWNING 5 Sheets Sheet 5- Filed June 6, 1934 Patented Sept. 24, 1935 UNITED STATES PATENT OFFICE My invention relates to a special type of awning of the general character illustratedand described in Letters Patent No. 1,941,308. issued to me on December 26, 1933; and comprises. more particularly. an awning structure made up of an assembly of parts. wholly or partly of metal. so arranged as to control the sun's rays being continuously directed upon a predetermined area beneath the awning structure and during the time of changing of the sun's altitude from horizon to zenith. while at the same time permitting a subdued light and ventilation to pass into the protected area. as clearly pointed out in my aforesaid Letters Patent.

More specifically considered. the purpose of my present improvements is to enable an awning structure of the type referred to above to be speedily built up by assembling a series of spacin! parts. with or without key forms. in proper relative association-with longitudinal ray controlling strips orslats which. together with longitudinal finishing or bounding strips. may be clamped in said relative positions by long bolts or tie rods, and whereby the inclined transverse supporting frames of the awning structure are largely made up of said spacing parts combined with the longitudinal ray controlling strips. the latter of which may be either of metal or wood. as preferred.

As pointed out in my aforesaid Letters Patent No. 1.941.308, the longitudinal awningstrips or slats are desirably made in "groups" of different depths and spaced equi-distant apart (Figs. 1. 2 and 3); or. as an alternative. said strips may each be of gradually increasing depth and of uniform distance apart (Fig. 12) or still further the strips may be spaced at different distances apart while being made of uniform depth (Fig.

13). to obtain the desired relative positions of the longitudinal strips or slats for controlling the sun's rays. In my present invention, the particular manner and special means for causing the assembly of the longitudinal stripsin one or other of the said relations. for regulating the control of the sun's rays, is an important part of the improvements. more particularly, because they permit the results desired by merely selecting the proper elements and-assembling them.

according to formula. in connection with the bolts or supporting means in predetermined relation.

Referring to the drawings: Fig. 1 is a. side elevation of an awning structure embodying my improvements and as applied to a window, the

Referring to Fig. 1. it will be seen that the awning structure is made up of a plurality of parallel strips or slats 2 arranged laterally atan angle and separated from each other byspacing members 3 of the character shown in Fig. 4, the thickness of which spacing members, gradually decreases from the lower end of the awning successively upward to the upper portion thereof. as clearly shown in Figs. 1, 8 and 12. said parts being clamped in proper relation by means of tension or tie rods 4. These tie rods 4 extend through the aperture 5 of each of the spacing finishing strips I 2 members I and also through apertures I in the longitudinal strips or slats I. The ends of the tie rods extend through longitudinal rolled metal and I respectively arranged along the upper and lower edges of the awning, and also extend through triangular-shaped abutment portions I and II which act as filling pieces between the finishing strips I and I and the adjacent faces of the spacing members I. It will be understood that by this assemblage arrangement of the strips I, spacing members I, and finishing strips I and I, the said parts are all clamped together by the tie rods I in the relative positions shown and provide a plurality of transverse inclined supports at two or more places along the length of the awning structure, as shown in Fig. I for example. It will also be understood that the abutment parts I and III may be co-extensive longitudinally with the rolled finishing strips 1 and I, if so desired, and in that manner increase the strength 0! the awning. From a reference to Figs. 1, I, I and 6, it will be seen that the width of the supporting structure, made up of the spacing members I, the bolts I and the finishing members I and I, is relatively narrow as compared to the length of the awning and. as above stated, may comprise two or more of such supports for any given length of awning. Furthermore, the spaces between the strips or slats I along the. length of the awning provide opportunity for air ventilation and passage 0! light, but restrict the passage of the sun's rays except upon a predetermined area beneath the awning structure, as fully described in my aforesaid Letters Patent No. 1,941,308.

The longitudinal strips or slats I are made of wood and may be reinforced, if so desired, by metallic edge pieces Ic, as shown in Fig. 2a, but I do not restrict myself in this respect as any other form or character of reinforcement may be employed for protecting the wooden strip or slat against warping.

As a suitable means for supporting the awning structure, the latter may be held in an inclined position, such as shown in Figs. 1, I and 12, by struts I I hinged at their lower ends to the window frame, as at II. and at their upper ends to lugs II projecting downward from one of the spacing members I. Aside from the support of the awning by the struts I I, the upper end of the awning has two of its spacing members I also provided with downwardly extending lugs II which are bolted. as at II, between two inclined brackets II. These brackets II have heel extensions II connected in spaced relation by rivets II, II and II, one of the rivets II being received in a hook-like recess III of a wall bracket II while the other rivet II acts in conjunction with the edges Ilia of the bracket II to lock the rivet I'l down into the recess II. As will be seen from Fig. 6, two inclined brackets II are employed, one upon each of the outer side walls of the wall bracket II, said wall bracket being secured to the window frame structure by means of the screws II. In this manner, the awning is supported at its upper end to the window frame and the weight of the lower end is sustained by the struts II. as before explained. In making the connection between the brackets II and the lugs II of the spacing mem-- bers I, the bolts II are extended through elongated slots II on the brackets II, such slots being of sufilcient length to permit the use of the bolts in connection with spacing members I of various thicknesses, such as would compensate for variations as shown in the awning of Figs. 1, 8 and i2.

As distinguished from the continuous transverse inclined support of the awning structure of my former patent hereinbefore referred to, my present improvements employ a series of spacing members I arranged alternately with the longitudinal strips or slats I, and which, by means of the tension belts or tie rods I, are clamped together in association to insure the parallel spacing of said strips from each other and so as to control the passage of the sun's rays; and at the same time the assemblage of the strips or slats and the clamping bolts or tie rods is such as to make the transverse suspension frames so produced rigid in character and capable of being made of any length and breadth desired. In carrying out this part of my invention, the spacing members I are threaded, according to formula, upon the bolts I alternately with the strips or slats I, and this is made possible by reason of the slotted character of the spacing members, as indicated at I, and by the apertures I through the strips or slats where they are clamped between the spacing members, as shown more particularly in Fig. 2. It will be seen that the strips or slats, as well as the spacing members, are arranged gradually in closer relation from the lower end of the awning to the upper end thereof, to definitely control or regulate the passage of the sun's rays through the spaces between the strips or slats upon a predetermined area beneath the awning structure, as graphically illustrated in dot and dash lines in Fig. l; but I do not restrict or limitmyselt in this respect as said strips or slats and spacing members 'may be arranged in grouped or other relation as fully set out in my aforesaid Letters Patent and also referred to in the present specification. It is, therefore, to be understood that the illustrations herein of the relation between thespacing members and longitudinal strips or slats are by way of examples only.

Referring again to the assemblage of the strips or slats with the spacing members and the cooperation of these parts in forming the supporting structure for the awning, I will point out that in threading the strips or slats, and also the spacing members, upon the tie rods I, the lugs II and II on the spacing members form additional supports for the strips or slats by providing grooves into which the edges of the strips or slats are received and definitely positioned. For instance, the lower edge of one of the longitudinal strips or slats fits into and is supported by the groove II of the spacing member I immediately preceding such strip, while the upper edge of the said strip or slat fits into the groove II of the following spacing member I and aids in supporting such member I, as shown in Fig. 2. In this manner, the tie bolts I are directly attached to the strips or slats and through said strips or slats are indirectly attached to the spacing members. The bolts are further attached to the spacing members by means of the finishing strips I and I and by association with the latter to the abutment parts I and II. When the strips or-slats I and spacing members I are threaded upon the bolts I, the tightening of the nuts II upon said bolts causes all of the parts to be drawn towards each other and cooperate in assuming a definite rigid relation whereby the awning may be handled and moved as a unit. This rigidity is enhanced by the presence of the finishing strips I and I as well as by the presence of the members I and II. -The spacing members, when of the form shown in Fig. I, are best formed by die casting or may be made in any other suit able or desirable manner.

While I have described the general construction and functioning of the parts which enter into the make-up of the awning per se. as shown in Figs. 1 and 2. I have not limited myself as to the composition or make-up of the longitudinal strips or slats or the spacing members, as these parts may be varied or modified in numerous particulars. some of which modifications I have herein illustrated and will now describe by way of examples. Furthermore. it will be understood that the general assemblage of the spacing mem-- bers. longitudinal strips or slats. finishing strips and abutment portions upon the ,tie rods or bolts.

is similar in all .the modified awning structures illustrated: and I will. therefore. in describing these modifications point out only wherein such modifications are found without-referring again to the general assemblage of the several parts making up the awning structure.

As a preliminary statement. I may employ longitudinal ray controlling strips composed either of wood or of metal. or combinations of these. as desired. The strips when formed wholly of wood, with or without the protecting edge pieces shown in Fig. 2a, are indicated at 2 in Figs. 1. 2. 6, 8. 9, l2 and 13, and will need no further description. The metal strips as employed in Figs. 7. 17 and 18 will be more fully described when referring to the modifications employed in the particular figures.

Referring to Fig. 7. it will be seen that the construction of the awning is similar to that shown in Figs. 1 and 2. with the singleexception that metal strips or slats are employed instead of wooden strips in the make-up of the awning structure. said metal strips being indicated at In and are threaded upon the tie rods or bolts 4 in conjunction with the spacing members in the same manner as are the wooden strips or slats 2. These metal strips 2a are spaced apart by the use of spacing members 3 of the same general character as that shown in Fig. 4 and employed in connection with the awning structure illustrated in Figs. 1 and 2. and operate in the same manner for regulating and controlling the sun's rays as do the wooden strips or slats.

Considering now the various modifications of the spacing membersemployed in connection with my present improvements, the following features are pointed out:

In Figs. 8 and 9. the spacing members are each made up of two parts la and lb. the former being of a box-like construction and the latter as a flat lid therefor. When these parts areassembled upon the tie rods and in connection with the longitudinal strips or slats I. the said parts 3a and 8b will be interposed between two adiacent strips or slats so as to. space them apart to the desired extent. The box-like portions la are made of varying thicknesses. similar to the spacing members 3 of Figs. 1 and 2, and this is accomplished by changing the channel depth of the part 3a. The lid part 3b requires no change in form. It is. however. provided with lugs extending down upon the outer sides of the part 8a to prevent side shifting of said part. The part to has at its'upper end a flange II extending forward of its closed surface and .also has lug portions 18 extending backward from the lower edges of the side walls for supporting the plate to (Fig. 11). said plate 3b having a fiange- 2'! which. in turn. supports the longitudinal strip or slat 2. The spacing members. comprising the parts In and lb of Figs. and 11, may be made as castings. but are preferably formed as stampings from sheet metal.

- Referring now to Figs. 12 and 13. the spacing members employed in this construction are of 5 shouldered grooves between which the longitudinal strips or slats are clamped. and are also provided with lugs 32 about mid-way of their length. said lugs fitting into spaces It and 34. respectively. in the spacing members 30. as shown in Fig. 13, to prevent shifting of the plates 30 and the spacing members So. In the construction of Figs. 12 and 13. it will be seen that the spacing members which are to be attached to the inclined brackets ll. instead of having the lugs formed integral with the body of the members them- 5 selves (as shown in Figs. 2 and 9. for example). have the lugs formed upon separate side flanges ll attached to the plates 30. as shown in Fig. 15. and these plates are. therefore. mechanically connected to'the brackets II substantially-as in the case of Figs. 2 and 9. It will also be seen that where these special members are employed. the spacing members 30 fit between the side flanges 35.

In Fig. 17, the construction therein shown is 5 similar to that shown inFig. 13, with the s ngle exception that the wooden strips or slats 2 of Fig. 13 have been substituted by metallic strips 2a of the character shown in Fig. 7. I I

Referring to Figs. 18 and 19. it will be seen that 40 in thevconstruction shown in these figures. a still further modified form of spacing member 3d and also a modified metallic strip or slat 2b are employed in the make-up of. the awning structure illustrated in these figures. v More specifically referring to these modified spacing members and metallic strips or slats. it will be seen that said strips or slats are provided with zigzag body portions 36. as shown in 'Fig. 18. which fit into notches l1 and cooperate with lugs 38 on the spacing member 8d. It will further be seen that in this construction of Fig. 18, the spacing members which are secured to the inclined bracket I! have the lugs for such attachment extended downward from the said spacing members, as in the ease of Fig. 2. for example. The zigzag portions 38 of the strips or slats act as supports between the strips or slats and the spacing members.

While I have shown adesirable bracket construction for supporting the awning in an inclined manner and securing it to the window frame. such cession to produce theproper relative assemblage of said parts; and may in this manner include in such assemblage the ray controlling strips or slats. and also the different sizes or proportions Y of. the spacing members with or without the key forms 32, as shown in Fig. 18, for example.

In storing the awning structure during the winter season, I may either disassemble the structure making up the awning and store the several parts; or the strut Ii may be disconnected at its hinged point I! and turned upward into engagement with a clip II and the awning, as a whole, allowed to swing about its axis 20 to a vertical position; or the awning structure may be disconnected from the wall bracket and hung up in a storage place, as preferred.

Furthermore, it will be understood that the severalconstructions of awning structure herein described may be reversed in their order of assemblage and inclination when the structure is to be used on that side of a wall which receives the sun's rays in its travel from zenith to horizon, to obtain the same desired results as are secured when the sun's altitude is changing from horizon to zenith.

Of course the awning illustrated and described herein may be modified and changed in many ways without departing from the invention herein set forth and hereafter claimed.
