Application 'file i June 6, 1914. Serial No. 843,523.
To all whom, it may concern Be it known that I, WILLIAM G. KENDAL citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Gurtain-Hooks, of which the following is a specification.
My present invention. relates to anew and useful form of fastening device and more particularly to a fastening device for use in securing the supporting cords of sash curtains, the object of my present invention being the provision of a simple fasteningdevice whichmay be readily applied to the sides or facing strips of the window casing to receive the ends-of either elastic or nonelastic sash curtain supporting cords and jto hold such cords against sagging, without the employment of any anchoring devices, such asknots inthe cord, or the liker A further object of my --invention is the provision of a fastener in the form of a hook having a threaded shank portion extending at right angles to the bisector of the bight portion of the hook in which the bill of' the hook is offset laterally at an angle to the plane of the body of the hook and its shank and further in which the bill of the hook extends above the line of the shank. By this construction, the insertion of the cord in the hook is greatly facilitated and strainexerted upon the cord 1 tendsto. increase the gripping action of the ho'okuponthe cord.
A still further object of my invention consists in constructing a hook so formed'that the cord maybe positioned directly between the bill and body portion of-the hook and extended in any direction therefrom, the outer face of the hook bill: being grooved transversely to receive the cord and prevent itsdisplacement if the cord is turned about the bill of the hook.
With these and other objects in view, my invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claim which forms a part, of this application.
In the drawings: Figure 1 is a perspective view of a pair. ofmy improved hooksin use as supports for a sash curtainybig. 2 is a side elevation of one of the hooks removed from the Window casing; Fig. 3 is a front elevation of the same hook; Fig.4 is atop plan view oflthe hook.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. y
The preferred embodimentof my invention comprises a fastener having accord engaging hook and attachingshank, the en tire fastener-being formed from a single lengthof relatively heavy and stiff resilient provided with screw threads 12 throughout thegreater portion of its length, As best shown in Fig. 2 of the drawings, thebill 10 of the hook extends at its free end-above the level of the shank 11, and as best shown in Fig. 3 of the drawings, tlliS billfiS offset or disposed angularly" with respecttothe plane of the body portion13ofthe hook and shank'll. The upper and=lower faces of theunthreaded portion of the shankl'l, adjacent the body portion13 of the hook, are flattened as shown at 14 in Fig. 4 in order that the hook may be readily grasped by a pair of pliers or a wrench to assist in threading it into place. For this reason it is unnecessary to grasp the hook proper in applying the fastener and all likelihood of springing the bill portion of the hook into the plane of the shank and body portion of the hook is therefore avoided.
Although, while not essential to the proper and effective workingof the fasteners,-I preferably construct the above fasteners in rights and lefts for use with sash curtains andother like devices in orderto insure somewhat more positive engagement with-the curtain cord, as will be later explained. That is, the bill portion of one hook Will, be directed toward the left. of
the shank, while the bill portion of the other will be directed toward the right, the
former being positioned at the left hand side of the window and the other at the right hand side. Also 1 preferably provide the intermediate portion of the bill ofthe hook with a transversely extending groove for a 'reason which w ll. behereinafterj explained.
In order to insure a clear understanding of the method in which my fastener 1s employed vas a. support for" sash curtains, I
have illustrated a pair of my fasteners so used, the fasteners being'threaded into the facing strips 16 at either side of the window casing 17 with thefree, ends of their b ll portions directed toward the outer edges of such'strips, that, is,;with the hook portion,
as a. whole, lyingin a substantially horizontalplane. v V 7 The sash curtain l8 is-provlded at its 7 upper edgewith a hem 19 through which is run the supporting cord 20, which is preferably circular in cross section and which may be either non-elastic or elastic as preferred, the latter usually belng found more efficient. The ends of the'cord are protected against ;,raveling. by beingbound with metal balls 21 or other like protectors. Aswill be 7 so appreciated, one'e'ndof the cord is wedged .in the .bight'portion of one fastener, after which the cord is drawn tight and wedged I a? 'in the bight portion of the other fastener.
. causing a still closer engagement of the cord 1 by the fasteners.
It is to. secure the full benefit of this feature that I prefer to construct the hooks in rights and'lefts, as previously' described.
If desired, the fasteners maybe attached to the window casing in such a manner that their bight portions are directed upwardly,
.in whichcase the cord is preferably secured in the fasteners in a slightly different manner, one'end of the cord being passed in- .wardly and wedged in the bight portion of the fastener at one side of the window and the cord then drawn about the bill of such I fastener to rest in the groove 15 and its other end drawnacross the bill of the other fas tener to rest in its groove 15 and then rebent or: turned and wedged in the bight portion of the latter fastener. This method ofsecuring the cord is of particular advantage in case an elastic cord is used as the elasticity of'the cord, by this method, is still further utilized to cause swinging of the bill pormovement through the hook.
tions of the fasteners into the planes of their body and shank portions to insure firm clamping or gripping of the cord. Also with this particular type of book construction, when the cord is applied in the above manner, the groove 15 holds the cord against "movement toward the mouth of the hook and the strain on the hook exerted by the cord swings the bill portion of the hook to additionally wedge the cord and hold it against This strain tending to additionally wedge the cord would, if it were not for the transverse groove, be apt to cause the cord to ride toward the throat of the hook and be released. Onthe other hand, the mere engagement of the cord in the groove, were it not for the angular disposition of the bill portion of the hook with respect to the plane of the other portions, would have practically no effect in wedging the cord in the hook.
It should be noted at this point that by extending the free end of the bill of the fastener or hook above the shank, as shown in Figs. 2 and 8 of the drawings, the application of the cord to the fastener is greatly facilitated as the cord may be merely drawn across the shank of the hook, stretched tightly,-and then moved outwardly slightly until it sinks into the bight portion of the hook. Y o
It will of course be understood, that I do not wish in any way to be limited to the specific details of construction, illustrated and described, as various changes, within the scope of the appended claim, may be made at any time without .in the slightest degree departing from the spirit of my invention.
The fastening devices will, preferably, either be formed of galvanized wire or the finished fastener will be galvanized, japanned, plated or otherwise coated to protect it from the elements.
The hooks, instead of being bent from wire, may be dropforged or cast out of brass or any other suitable metal.
Having thus described the invention, what is claimed as new is:
A fastening device formed from resilient wire bent to provide a V-shap'ed hook having a bodyportion, a bill portion and a shank portion extending at substantially right angles to the biseetor of the angle of the hook between the bill and body portions, the bill portion of the hook so formed, being bent laterally to extend at an acute angle to the plane of the body and shank portions of the hook and being formed in its outer face with a transverse groove adapted, when a cord is wedged in the V-shaped bight portion of the hook with that stretch of the cord subject to strain, wound about the bill of the hook to receive said wound portion of the cord,
whereby when the cord is under strain, the
groove Will hold the cord against movement In testimony whereof I aflix my signature toward the mouth of the hook and the strain in presence of two Witnesses.
on the hook Will swing the bill toward the WILLIAM G. KENDALL. [L. s.] plane of the body and shank portions of the Witnesses:
5 hook to additionally Wedge the cord and J OHN J. IRISH,
hold it against movement through the hook. LoUIs E. KAPPLER.
