B. E. BARNES AWNING OPERATOR Oct. 3, 1950 Filed July 19, 1947 Patentecl Oct. 3, 1950 UNITED STATES PATENT OFFICE AWNING OPERATOR Bruce E. Barnes, Youngstown, Ohio Application July 19, 1947, Serial No. 762,078
This invention relates to mechanical apparatus for raising and lowering conventional window awnings and the primary object of the invention is the provision of a simple yet dependable assembly operable from inside the window for raising and lowering the awning and which does not require any modification of existing and/or conventional awning structures for its application. The most commonly used window awning is a sewn canvas canopy like device which is fastened along its upper edge to the window frame or trim in a more or less permanent manner and which has at least its lower and outer edge secured to the outer reach of a U-shaped bracket which is pivotally secured to the sides or jambs of the window at points spaced downwardly from the top of the window. To raise the awning it is common practice to employ a rope or cord and a system of pulleys so that by simply pulling downward on a length of cord the frame referred to is pivoted upwardly against the building thus raising the awning. The present invention provides an improved and materially simplified device for taking up and paying out the awning operating cord whereby theawning may be readily raised and lowered by.manipulation of an element inside the building.
A further object of the invention is the provision, in apparatus of the general character out lined above ofan improved operating lever or crank which may be permanentl attached to the assembly and which yet may be readily moved to an inconspicuous recessed position in the window frame when not in use.
Another object of the invention is theprovision of an improved ladder-chain arrangement for raising and lowering the pivoted skirt frame of a cloth awning.
The above and other objects and advantages of the invention will become apparent upon consideration of the following detailed specification and the accompanying drawing wherein there is disclosed certain preferred embodiments of the invention.
In the drawing: a I a Figure 1 is a plan view, partly in section of an awning operator constructed in accordance with the principles of the invention;
Figure 2 is a side elevation, partly in section, of the assembly of Figure 1; and
Figure 3 is a plan view, partly in section, of a modified form of awning operator constructed in accordance with the principles of the invention.
Referring now to the drawing in detailv and more particularly to Figures 1 and 2 thereof the 5 Claims. (01.254-186) reference numeral ll! desi nates an exterior trim board of a conventional window frame while the reference numeral l l designates an interior trim board of the window frame assembly and, as is well known, the space intermediate these trim members is commonly taken up by the jamb of the wind-ow frame. In some instances this jamb may be of box-like construction to accommodate counterweights if the latter are used in the assembly. In either construction it is entirely practicable to drill a hole entirely through the jamb and trim boards from the interior to the exterior, of the building and in accordance with my invention such an aperture is utilized to accommodate an operating shaft for the awning operating device whereby the awning may be raised and lowered by a person standing inside the building. The manner and apparatus in and by which this is accomplished will now bedescribed in detail.
In the embodiment of Figures 1 and 2 I provide a reel iii to receive the awning-operating cord [3 and, as shown, the reel i2 is fixed on a shaft M journaled in brackets l5 extending outwardly from a base plate l 6 which in turn is rigidly secured to the board l0 by means of wood screws or the like, not shown. The plate It may be provided with an integral tab which is bent forwardly at I? and upwardly at I8 to provide an outboard bearing mount for a shaft 19 mounting a worm 20. Shaft i 9 is also journaled in an aperture formed in the base portion of the member H5 in alignment with the bearing aperture formed in upturned portion l8 of the member [6 and the shaft I9 is provided with an elongated squared portion projecting a considerable distance inwardly of the base member it into the aperture in the window frame jamb described above. Meshing with the worm 20 is a worm wheel 29 which is keyed onto the shaft id and it should be apparent that upon rotation of the shaft IS the drum IE will be rotated at a reduced speed to take up or pay out the cord l3, depending on the direction of rotation of the shaft IS. The gears 25) and 2! are preferably die-cast products and, if desired, they may be enclosed in a suitable housing although this is not completely necessary due to the weather resistant nature of various metals most suitable for die-casting. Likewise, the other exposed parts of the assembly are preferably formed of suitable corrosion resistant metal by die-casting or other economical production methods.
Secured in the aperture in the trim board. 5 l is a sleeve 22 having an integral flange 23 overlyin the interior face of the board II and a short inwardly projecting portion 24. Rotatably and slidably mounted in the sleeve 22 is a tubular member 24 having a reduced and squared inner end portion 26 to slidably receive the squared projection of the shaft I9. To limit the inward sliding movement of the tubular member 25 a ring 21 is brazed or welded to its outer periphery for engagement with the inner end of the sleeve 22 as shown in Figure 1,
Pivotally secured to the end of member 25 opposite the portion 26 is a crank arm 28 having a longitudinal bore passing through it from end to end to receive a coil spring 29 and the two steel balls 30. Pivotally connected to the free end of crank arm 28 is a handle 3| havin an end enlargement 32 and the diameters of the arm 28 and handle 3| are generally commensurate with the diameter of the tubular member 23. Further, the axes of pivotal interengagements of the arm 28 with the tubular member 25 and the handle 3| are parallel so that these three parts may be relatively oriented as shown in Figure 1 to form a crank handle to rotate the member 25 and consequently the shaft [9 or alternatively, so that these three parts may be pivoted into alignment with each other and slid longitudinally through the sleeve 22 as shown in Figure 2. To assist in maintaining these three parts in either of their alternative relative positions there is provided on the end of member 25 a block 33 having indentations 34 spaced 90 apart and adapted to be en gaged by one of the two spring-pressed steel balls 353. A similar block 35' is provided on the end of handle 3i opposite enlargement 23 for coaction with the other of the two spring-pressed steel balls 33. The enlargement 23 on the handle 3! not only limits the inward sliding movement of the collapsible crank assembly but also provides a convenient thumbhold for the withdrawal of the collapsed crank from its recessed position in the sleeve 22 when it is desired to utilize the awning operator.
By referring to Figure 1 it will be apparent that with the parts positioned as shown, rotation of the crank comprised of the members 28 and 3i will drive the shaft l9 and also the reel i2 by reason of the squared interconnection between shaft l3 and the member 25. Thus the awning to which the operating core I3 is attached may be readily raised or lowered from inside the building and this is true regardless of whether or not the window sash is open, Upon completion of the desired manipulation the crank may be straightened out or collapsed by pivoting the arm 28 into alignment with the member 25 and the member 3| into alignment with the member 28 after which the collapsed or straightened assembly may be slid through the sleeve 22 until the enlargement 32 engages the projection 24. This longitudinal movement of the collapsed crank assembly is made possible, of course, by the sliding interconnection between the shaft l9 and the member 25. With the parts recessed as shown in Figure 2 of the drawing only the enlargement 32 and the flange 23 of the sleeve 22 is visible from the inside of the building and this appears simply as a decorative button.
In the embodiment of the invention shown in Figure 3 a sprocket wheel 34 and a ladder-type of chain 35 in mesh therewith replace the reel l2 and cord 13 of the embodiment of Figure 1. To maintain the chain in mesh with a considerable portion of the periphery of the sprocket 34 I provide a pulley 36 which is journaled in suitable lugs, not shown, formed integral with and projecting outwardly from the bottom edge of the base plate I6 for rotation about an axis generally parallel with the axis of rotation of the shaft l4. As shown, the pulley 36 is positioned forwardly of the axis of the sprocket 34 While the chain reach extending upwardly from the sprocket 34 is on the back face of the sprocket. It will be understood that the upward extension of the chain is entrained over a pulley mounted at the head of the window and thence extended to engage the outer bar of the U-shaped awning frame. Alternatively, the chain may extend upwardly to connect with the awning cord only a sufficient distance to enable the travel of the chain over the sprocket 34 to raise and lower the awning its full extent. Thus, upward movement of the chain 35 lowers the awning while downward movement of the chain raises the awning. The excess chain which accrues upon raising of the awning may be housed in a suitable enclosure positioned below the pulley 36 or it may simply be allowed to dangle as at 31.
To rotate the sprocket 34 I preferably utilize the worm wheel 2| and the worm 20 as in the case of the embodiment first described, but in the specific device illustrated in Figure 3 somewhat longer shaft 38 is employed to mount and drive the worm 20. This shaft 38 is of sufficient length to extend entirely through the sleeve 22 thus providing an interior projection for reception of a conventional crank handle 39. As shown, the shaft 38 is preferably square in cross-section and, of course, the mounting aperture in the crank 39 is likewise of square contour so that an effective driving interconnection is established simply by slipping the crank handle onto, the inwardly projecting end of the shaft 38. The crank 39 is loosely mounted on the end of the shaft 38 so that it may be readily removed when desired. It should be understood, however, that the collapsible crank assembly of the embodiment of Figures 1 and 2 may as well be employed in place of a more conventional operating arrangement of Figure 8.
It should now be apparent that I have provided improved mechanical apparatus for raising and lowering conventional window awnings which accomplishes the objects initially set out. The apparatus of the invention is simple in design, economical to produce, and readily applicable to existing and/ or conventional window frames and awning structures. Further, the invention pro-- vides practicable arrangements for operating the awnings from inside the buildings while yet providing for the recessing or removal of the interior operating apparatus whereby the architectural beauty of the interior of the building structures is not interfered with. The above specifically described embodiments of the invention, however, should be considered as illustrative only as obviously many changes may be made therein without departing from the spirit or scope of the invention. Reference should therefore be had to the appended claims in determining the scope of the invention.
