`Application filed October 8, 1920. Seria] No. 415,581.

To all whom t may concern.' y

Be it known that I, THOMAS BENsoN, a citizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Cord Tighteners for Awning Operators,

of which the following is a specification.

The objeotof thisinvention is to provide a cord tightener for awning Operators whereby .theawning may be raised and lowered from theinside of the building and without the necessity of the window or the like be` ing opened for the entry of the elements.4

With this and other objects in view as will be more speciiicallyfpointed out in the Afollowing specification and claims, reference.

'willjbehad to the accompanying drawing forming a part of this specification. and wherein like numerals of reference designate corresponding parts throughout the several views, in which a Fig. 1, is an elevation of a fragment of a window with awning lowered viewed from the inside of the building,

Fig. 2 is a vertical transverse sectional view thereof,

Fig. 3 is a front elevation view of the cord tightener,

Fig. 4 is a Side elevation view of Fig. 3,

Fig. 5 is a horizontal Sectional view taken through Fig. 4 on the line 5 5,

Fig. 6 is a front elevation of a fragment of the window viewed from the inside of the building, and

Fig. 7 is a longitudinal vertical sectional view through the cord guide.

Referring to the drawing, reference numeral 1 denotes the wallof a building, in which is set the usual window frame 2, having the usual guide strips 3, 4 and 5. Between the guide strips 3 and 4 slides the lower window sash 6, while between the .guide strips 4 and 5 slides the upper Sash 7.

lhe strip 3 extends down the sides of the sash and across the top thereof, and in a like manner extend the other guide strips 4 and 5. The awning 8 is attached in the usual manner as by fastenings 9 to the building and has the usual operating cord 10 passing through the usual screw eyes 11. lnstead of the operating cord extending down the outside wall of the building and there fastened, the Same passes from said eyes 11 through a tubular guide 12, thence down the inner face of the window framing where it is adjustably attached to a cord tightener 14 which is slidably adjustably mounted on?.

a ratchet rod 15, Secured at its Opposite ends to .the window framing. The guide Strip sections 3 at the top and one side of the window framing are out out for the accommodation of the cord guido.'`

member 12, as illustrated in Fig. 6, and similarly are the guide strips 4 and l5` cut away. This permit-S the cord guide member to be placed in the extremecorner of the window frame and there secured byscrewswl the@V heads of which are aermitted to pass through the outer wall of the cord guide due to the enlargedv openings 17, and said openings 17 receive the screw driver inplacing these screws. In Fig. 6, it will further be notedI that the upper sash 7 (and the lowerfsash also if desired) is notched or cutout 'as at 18 in Yone corner for the accommodation'of the cord guide `member,and by this conand between the guide strips 4yand; 5v at the top, no openin is presented for entrance of struction, when the upper sash is fully raised@ and easy passage of the awning operating n' cord 10 through the cord guide member 12, said member is equipped at its front end with a roller 20, in the plane of the lower wall of the guide member and journaled between two downwardly extending ears struck from the body of said cord. guide member. Also, at its rear end, other rollers 22 are provided in the plane of the side walls of the cord guide member and journaled between extensions 23 of said cord guide member.

The cord tightener 14 comprises two sections 24, 25 secured together by transverse bolts 26. Upon one of the sections, in the drawing, section 24, is mounted a cleat 27 to which the awning operating cord 10 is secured; and in the lower end of one of these sections, shown in the drawing as Section 24, is insertedv a screw eye 28 which serves as a handle for adjusting the cord tightener on the rod 15. At intervals, the rod 15 has ratchet teeth 29, to hold the cord tightener in adjusted position, through the medium of a pawl 3() pivoted to the other said section 25 of the cord tightener. This pawl operates in a recess 31 and is normally en gaged with said rod 15 due to being under the tension of a spring 32 attached to said pawl and to a screw or pin 33 and located within a recess 34. When the two section.

24 and 25` are secured together, the inner wall f member 24 closes the open side of the recesses 3l and 34. Embedded within the sections 24 and 25 at both the upper and lower ends are guide lingers 33, the projecting ends of .which are L-shaped and facing each other to embrace the ratchet rod 15.

In operation, when it is desired to raise the awning, the cord tightener is pulled downthe'ratchet rod 15, by releasing the pawl and inserting a finger in the screw eye 28, or thepawlneed not be released since it will ride over the ratchet teeth of the rod vand when the awning has been fullyl raised will enter behind one of the ratchet teeth and retain the awning in raised position. To lower the awning, the pawl 30 is disengaged from .the ratchet teeth 29 and the cord tightener permitted to ride up the ratchet rod until the awning is fully lowered. By regulating the position of the cord tightener along the ratchet rod with respect to the position of the awning before attaching the cord to .the cleat 27, engagement of the pawl with the ratchet teeth at the proper time is insured,

Of course it will be understood that it is the intention to alter and modify the structural details within the scope of the claims, andto-makesuch other minor changes as will improve and perfect the invention.

Nhat is Vclaimed as lnew and desired to be secured by Letters Patent is l. A cord tightener, comprising a ratchet rod and a slider mounted thereon, said slid- :n

and a cleat on one of said sections for the L attachment of the cord. Y

2. A cord tightener, comprising a ratchet rod and a slider mounted thereon, said slider comprising two matching sections, each section being provided with an L-sha-ped finger and the ngers closing about said rod when the sections are'matched, one of said sections being provided with a recess, a spring pressed pawl mounted pivotally within said recess, the other of said sections closing said recess when the sections are matched, a cleat on one of said sections for the attachment of the cord, and a screw eye inserted into the lower end of one of said sections as a handle.y

In testimony 'whereof'l have hereunto set my hand in presence of two subscribingwitnesses.
