Description

Patented Oct. 26, 1937 UNITED ES SHADE PULL Illinois Application July 27, 1934, Serial No. 737,146 5 Claims. (01. 15640) This invention relates to a shade pull, and a primary object of the invention is the provision of a device of this character, economical to manufacture, extremely durable and eflicient in operation and neat and attractive in appearance.
A further object resides in providing a shade pull comparatively plain in appearance and form so as to eliminate expensive and tedious operations, such as crocheting, for covering previous types of shade pulls, which will not gather dust or become soiled to an appreciable degree over a long period of time and which is extremely easy to clean.
Other objects will appear hereinafter.
The invention consists in the combinations and arrangements of parts, hereinafter described and claimed.
' The invention will be best understood by reference to the accompanying drawing which forms a part of this specification, and in which:
Fig. l is a front elevational view of the article of the invention operatively connected to a roller shade;
Fig. 2 is a side elevation of the device shown in Fig. 1;
Fig. 3 is a plan view of a strand of material which may be advantageously used to form the main body portion of the device, centrally cut away to illustrate the interior construction;
Fig. 4 is a plan view of the strand of the main body portion after the first bending operation in the process of manufacture in which the central portion is bent to form a curve preparatory to final bending operation which provides a loop formation;
Fig. 5 is a view of the final position of the strand or main body portion after the ends have been bent inwardly and placed in juxtaposed relation;
Fig. 6 is a top plan view taken on the line 6-4: of Fig. 5;
Fig. 7 is a perspective view of the securing end closure clip or cap adapted to embrace and secure the exposed ends of the strandfollowing the final formation shown in Fig. 5;
Fig. 8 is a View of the device with the closure and securing clip applied and prior to the clinching operation;
Fig. 9 is a View, similar to Fig. 8, showing the device after the clinching operation in which the closure clip is clinched centrally and longitudinally to tightly engage the ends of the main body strand;
Fig. 10 is a plan view taken substantially on the line ll0 of Fig. 9;
Fig. 11 is a horizontal sectional View taken substantially on the line ll-H of Fig. 9; and
Fig. 12 is an enlarged vertical sectional view taken substantially on the line l2l2 of Fig. 10.
Referring to the drawing, the preferred embodiment of the device comprises a main member or strand 6% of flexible material capable of being bent into the formation disclosed. In actual practice it has been found that a strand approximately five-sixteenths of an inch in diameter and approximately four and five-eighths of an inch in length provides a pull of proper size, although it will be understood that these dimensions may be varied as occasion or preference might require.
In order to obtain both flexibility and a certain 15 degree of resiliency in the pull loop, a material that has been found eminently suitable for the purpose is the present type of high tension insulated wire used for ignition purposes in automobiles. This material eliminates the objectionable clicking sound produced by materials such as metal, celluloid, bakelite or the like, when the pull is dropped or blown against a window pane. This material comprises a central twisted copper wire core l6,covered by a rubber or resilient composition I! and having a tightly woven braided covering l8 finished with a coating of shellac. This high tension wire may be then covered with a braid of cotton, silk or other textile material to give a finished appearance.
After the strandhas been formed as shown in Fig. 5 to provide a lower curved portion 19 and converging intermediate portions 2!) and 2|, ter- 7 minating in juxtaposed end portions 22 and 23 respectively, the closure end securing clip 24 is applied.
The closure end securing clip 24 is generally elliptical in cross section as shown in Fig. 7, is provided with an upper closed end and a lower open end whereby the member may he slid over the ends 22 and 23 to the position shown in Fig.
8, and the member is preferably chromium or nickel plated to enhance durability and appearance. After this operation the member 24 is preferably tightly locked in engagement by a clinching operation on opposite sides 25 and 26 to produce a longitudinal depression upon the opposite sides.
For securing the pull to a connecting cord, the closed end of member 2 3 may be provided with an opening 27. An open-eye needle carrying a looped connecting cord 28 is forced between strand ends 22 and 23, which is feasible because of the resilient and compressible character of the strand material, and cord 28 is then pulled through opening 2'! to bring the knotted extremity 29, which is larger than opening 21, in contact with the inner surface of the closed end of member 24. These parts then assume the relative positions shown in Fig. 12 and it will be noted that the convex surface of the closed end of member 24 serves to provide a space 30 for knot 29. This manner of attachment is exceptionally competent and efficient for the purpose and eliminates unsightly exterior knots or other fastening means.
i The device is then secured to the shade by passing the closed end of cord 28 through eyelet 3| and then passing the device through the closed end to bring the cord and-pull in the position, shown in Figs. '1 and 2, in the usual manner. It
disclosed and described but may be varied by adopting other curved or polygonal formations.
While I have illustrated and described the preferred form'of'construction for :carrying my invention into effect this iscapablecof variation and modification without departing from the sphere of the invention. I therefore do not wish tobe limited to the precise details of construction set forth, but desire to avail myself of such varia' tions and modifications as come within the scope of the appended claims. f
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
'1. A shade pull of the character described,
comprising a strand of flexible material bent to characterized by a transparent dirt resisting, waterproof coating for said loop, substantially as described.
4. A shade pull comprising a section of heavily insulated wire bent to form a loop'with its ends in parallel relation, a ferrule enclosing and securing said ends, an ornamental covering for said loop, a coating of transparent dirt resisting mate' WALTER HERRMANN.
