R. I. MILLS.
ADJUSTABLE'SHADE.
APPLICATION FILED MAR. 1. ms.
1,274,925.. I Patented Aug. 6,1918.
RICHARD I. MILLS, OF ROOSEVELT, UTAH.
ADJUSTABLE SHADE.
Specification of Letters Patent.
Patented Aug. o, 1918.
Application filed. March 1,1918 Serial No. 219,894.
To all whom it may concern:
Be it known that I, RICHARD I. MILLS, a citizen of the United States of America, residing at Roosevelt, in the county of Duohesne and State of Utah, have invented certain new and useful Improvements in Adjustable Shades, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to an adjustable shade for lamps and the like and has for its object the production of a simple and ellicient means whereby the sides of the shade may be swung outwardly to a position for increasing the radiancy of the lamp upon which the shade is used.
Another object of this invention is the production of simple and efficient means for holding the hinged portion of the shade against accidentally swinging to a closed position.
With these and other objects in view this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed.
In the drawings:
Figure 1 is a side elevation of the lamp shade, certain portions thereof being shown in dotted lines as swung outwardly.
Fig. 2 is an enlarged vertical section through one side of the lamp shade.
Fig. 3 is a top plan view of the top plate, or blank from which the top plate is formed.
Fig. 4 is a plan view of the blank from which one of the side sections or plates of the upper portion of the lamp is formed.
Fig. 5 is a plan view of the blank from which one of the lower hinged sections of the lamp shade is formed.
Fig. 6 is a section taken on line 6-6 of Fig. 1.
Fig. 7 is a section taken on line 7-7 of Fig. 1.
Fig. 8 is a section taken on line 88 of Fig. 1.
Fig. 9 is a horizontal section taken on line 9 9 of Fig. 2.
By referring to the drawings it will be seen that 1 designates the top plate which is provided with centrally located parallel shades 2 having a plurality of radiating shades 3 extending therefrom which shades are adapted to bend upwardly for fitting snugly upon the lamp socket 4.
The lamp shade is formed rectangular or square and comprises a primary pair of side plates 5 and a pair of auxiliary side plates 6. Each of the plates 5 and 6- are provided with overhanging flanges 7 fittin snugly over the top plate 1 and being soldered or otherwise fixed thereon. The side plates 6 are provided with side flanges 8 which side flanges 8 overhang the side plate 5 as shown clearly in Fig. 1 of the drawings. The lower edge of each side plate 5 and 6 is provided with a plurality of elongated slots 9 for producing a plurality of tongues 10. The alternate tongue 10 is folded backwardly upon itself and constitutes a hinge 11 for fitting over the pintlepin 12.
A pair of primary hinged plates 13 are secured to the plates 5 and a pair of auxiliary plates 14 are secured to the plates 6. These plates 14 are provided with under hanging flanges 15 which under hanging flanges 15 extend under or ungder-lap the edges of the plate 13. Each plate 13 and 14 is provided with a plurality of slots 16 formed near the upper edge thereof for dividing the upperedge of the plates 13 and- 14 into a plurality of tongues 17. Each alternate tongue 17 is bent backwardly upon the top of this respective plate for forming a hinge and fitting snugly over and upon the pintle pin 12. In this manner the upper plates 5 and 6 will be fixedly hinged to the plates 13 and 14 or either to the alternate tongues 17 and the plates 13 and 14 and the alternate tongues 10 of the plates 5 and 6 extend parallel with the top of their respective plates, and tongues of the upper plates fitting between the tongues of the lower plates, the edges of the tongues frictionally engaging each other thereby causing the side plates 13 and 14 to be swung and easily held in an adjustable position with respect to the plates 5 and 6. It will be seen that any one of the plates 13 or 14 may be swung outwardly, to suit the convenience of the operator.
What is claimed is A lamp shade, comprising a top plate, on
" tending through the bent back tongues of .In testimony whereof I hereunto aflix my in parallelism With its side plate, shade ing to their ends, constituting stops for plates provided With alternating sets of limiting the pivotal movement of the shade 10 tongues, similarly constructed to the sets of plates when swung to their normal position,
tongues of the side plates, a pintle pin exsubstantially as shown and described.
the side and shade plates for pivotally sesignature.
curing saidplates together, and the tongues 7 provided with the straight portions extend- RICHARD I. MILLS.
Copies of this patent m ay be obtained for five cents each, by addressing the Qommissioner of Patents. Washlngtomifl. C.
