UNITED STATES PATENT OFFICE.
BERNARD HOLZ, OF CLEVELAND, OHIO, ASSIGNOR TO THE FRANKELITE COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.
HARP OR LAMP-SHADE HOLDER.
Application filed May 29, 1924. Serial No. 716,638.
To all whom it wm concern.
Be it known that I, BERNARD How, a citi- Zen of the United States, and resident of Cleveland. in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Harps o-r Lamp- Shade Holders, ofwhich I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
The objects of the invention are to provide an improved harp or lamp shade holder and improved method of constructing the same by means of which all cost of machining is avoided, the cost of production is materially lessened, and the speed of construction is greatly accelerated.
The invention includes a simple and practical form of harp preferably stamped from a strip of cold rolled steel and completed for shaping in one operation after which it is only necessary to bend the same into its final form to adapt it for use.
The. invention comprises the harp and the peculiar mode of construction of the same, illustrated in the accompanying; drawings,
hereinafter more fully described, and specitied in the claims.
In the accompanying drawings Figure 1 is a side elevation of the device. Figure 2 is an edge elevation thereof. Figure 3 is a plan of the upper portion thereof. Figure l is a bottom view thereof, Figure 5 is a plan of the. extended metal strip before it has been bent into shape, and Figure 6 is an edge elevation thereof.
In these views A is an integral metal strip or band bent into the form of a harp and having a loop at the upper end and having its lower extremities C, C formed into over lapped registering looped eyes. The upper end of the loop is flattened at B, and the inwardly curved arcs formed at the ends of this flat portion form bearings for the lamp shade S which rests therein. Outwardly curved arcs E, E are oined to the inwardly curved arcs and form the sides of the harp.
A hole F for the insertion of a screw F or other fastening device is punched centrally through the flat portion of the loop. The screw F, shown in Figure 1, serves to attach the shade cover S to the harp. The
lower extremities of the harp are longitudinally split at G, G, and the sides of the Figure 5 the appearance of the finished band is shown after it has been stamped and punched at- F and the base portions have been split at their ends at G and spread apart to form loops or eyes H all of which may be accomplished in one operation in suitable punching and slitting dies.
In F igure 1 the harp is shown after it has been shaped for final use and the shade and lamp havebeen secured in position thereon. In this manner the production of the harp may be speeded up, and harps may be constructed in large quantities for a fraction of the cost that would be necessary if machined parts were employed.
Having described the invention what I claim as new and desire to secure by Letters Patent is: I
1. In a shade holder a harp shaped fiat metal stamping, having a flat upper end provided with an opening for receiving a binding screw, the extremities of said flat portion on either side of said opening terminating in inwardly curved arcs forminp bearing surfaces for the upper edge of said shade, the sides of said harp extending thence outwardly and downwardly and terminating in flattened overlapping and register-mg eyes.
2. In a shade holder a harp shaped metal stamping provided with a central straight portion having inwardly curved seats at its ends, adapted to support the shade thereon. the sides of said loop being thence extended outwardly and downwardly and having their lower ends turned inwardly and overlapping each other, said lower ends being longitudinally split and separated to form registering eyes, said straight portion being provided with an opening to receive a shade holding means. 1 A
In testimony whereof, I hereunto set my hand this 30th day of April 1924.
, BERNARD HQLZ.
