' SHADE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 588,984, dated August 31, 1897.

Application filed November 12 1896, Serial No. 611,880. (No model.)

To aZZ whom it may concern:

Beit known that I, MORRIS D. GREENGARD, a citizen of theUnited States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Shade-Holders,of which the following is a full,

' clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in shade -holders for electric incandescent lamps; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims. 7 I

In the drawings, Figure 1 is a top plan View of my invention. Fig. 2 is a vertical section ontheline a: a: of Fig. 1. Fig. 3 is an elevation of a section of the outer face of the shadering. Fig. i is a section on line 1 y of Fig. 3, and Fig. 5 is a perspective detail of the shadeclamping wing.

The object of my invention is to construct a simple shade-holder whose frame shall be preferably constructed of a single piece of metal and the number of whose movable parts shall be reduced to a minimum, thereby producing a product which will be light, easy to construct, and cheap.

A further object is to simplify the general mechanical construction thereof,-as will be better apparent from a detailed description j of the invention, which is as follows:

Referring to the drawings, 1 represents the shade-ringthat is, the ring to which the shade is secured-the said ringhaving form ed integrally therewith a series of pairs of Webs 2, inclined to the general plane of the circle or perimeter of the shade-ring, one member of each pair of webs being connected at its yielding end, or that farthest removed from the shade-ring, with the nearest member of the next adjacent pair by a clamping-band section 3, the several sections forming collectively a clamping band by which the socket of the lamp can be seized or embraced. The shade-ring, the clamping-band, and connecting-Webs thus form a single integral frame, the said frame being cut or stamped from a single piece of metal. The members of each pair of webs are slightly separated from one another, this arrangement permitting their upper yielding ends-that is, the

each web is an operating or actuating lever 5, the free end of the short arm of which is pivotally secured to a lug 6, formed along the upper portion of the adjacent edge of the second member of the pair of webs, whereby upon tilting or swinging of the long arm of the several levers in the direction indicated by the arrow in Fig. 1 the yielding ends of the successive pairs of Webs will be brought together, thereby drawing together thebandsections and reducing the diameter of the clamping-band (see dotted position of the same in Fig. 1) and firmly embracing or seizing the lamp-socket. To retain the lever in its position after the clamping-band has been contracted, or, in fact, in any position to which it may betilted, and to thus prevent the clamping-band from expanding upon the release of the lever, I provide the long arm of the latter with a knob 7, which engages one of a series of depressions 8, formed at the base of the web carrying the lug 6, the resilient character of the said long arm always bringing the knob into engagement with said depressions. Of course any mechanical equivalent of this arrangement comes within the spirit of my invention.

Out from the depending flange of the shadering and disposed in the general plane of the circle or perimeter of the ring, but still adhering to the body of the flange, are a series of yielding friction-bands 9, each having a medial inwardly bent or looped portion 9', provided with a series of indentations 15 on its outer surface,for a purpose to be presently described. Gut also from the flange of the shade-ring and located opposite the looped portion of each friction-band and deflected outwardly from the periphery of the ring are the lugs 10 11, between each pair of which is pivotally mounted a shade-clamping wing 12, having an inwardly-deflected member 12, passing inwardly into the ring through an opening of the flange cut from said flange at the base of lug 11, the said member 12 serving to engage the shade introduced into the ring. Forming a part of the wing 12 and located oppositethe indentations of the friction-band 0 is a finger 13, adapted to ride over the indentations of said .band, this arrangement serving to retain the wing 12 and its inner member 12 in any position to which it is tilted and prevent accidental release of the shade from said wings. The means for effecting frictional engagement between the friction-band 9 and the finger 13 of the wing is only one of several constructions by which the said wing may be controlled, it being understood that any equivalent means comes within the spirit of my invention. \Vhen the clamping-wings are swung open, their inner deflected ends or members 12normal1y bear along the inner surface of the shade ring or flange thereof, as seen in dotted lines in Fig. l. The maximum distance to which the members 12 can be swung inwardly (for gripping the shade) corresponds to the position when said members are substantially in line with the radius of the circle of the shadering, (see Fig. 4,) the wing being limited in its movement in that direction and being prevented from passing beyond this point by the base of the member 12 coming in contact with the shoulder ll of the opening cut at the base of the lug 11 for the passage inwardly of the said member 12 of the oscillating wing,

It is apparent that my device might be altered in many details without departing from the spirit of my invention, and I do not limit myself to making the holder-frame of a single piece of metal.

Having described my invention, what I claim is- 1. In a shade-holder, a suitable shade-ring, a series of webs arranged in pairs carried by the ring, a series of clamping-band sections, connecting the free end of one member of each pair with the nearest member of the next succeeding pair of webs, a controllinglever pivoted to one member of each pair and having the free end of one arm thereof secured to the free end of the other memberof the same pair of webs, and means for retaining the said lever in any position to which it may be tilted, substantially as set forth.

2. In a shade-holder, a suitable shade-ring, a series of webs arranged in pairs the members of which are slightly separated from one another, a series ofclamping-band sections connecting the free end of one member of each pair with the nearest member of the next succeeding pair of webs, a controlling-lever pivoted to one member of each pair and having the free end of one arm thereof pivotally secured to the free end of the other member of the same pair of webs, and means for retainin g the said lever in any position to which it has been tilted, substantially as set forth.

Ina shade-holder, a suitable shade-ring, a series of pairs of webs carried by the same, a series of clamping-band sections connecting the nearest members of each pair of webs, a

lever pivoted to one member of each pair and having the free end of one arm thereof pivotally secured to the free end of the other member of the same pair, a knob carried by the actuating-arm of the lever, and a series of depressions formed along the second member of the pair of webs with which said knob engages, substantially as set forth.

4. In a shade-holder, a suitable shade-ring, means for securing the same to the socket of a lamp, a series of wings pivoted along the periphery of the ring for gripping the shade introduced thereinto, and suitable devices for frietionally holding the wings in any position to which the same have been tilted, substantially as set forth.

5. In a shade-holder, a suitable shade-ring, a series of wings pivoted along the periphery of the same for gripping the shade introduced thereinto, a finger forming a part of each wing, and a frietion-band cut from the peripheral flange of the ring against the surface of which the said finger is adapted to ride, substantially as set forth.

6. In a shade-holder, a suitable shade-ring, a series of wings pivoted along the periphery thereof, an opening cut from the flange of the ring through which one member of each wing is adapted to be inserted for gripping the shade introduced into the ring, a frictionband cut from the ring opposite the wing, a series of indentations formed along the outer surface of said friction-band, and a finger carried by each wing for riding over said indentations and thus retaining the wing in any of its tilted positions, substantially as set forth.

7. In a shade-holder, a suitable shade-ring, a series of pairs of lugs formed along the same, a wing pivoted between each pair of lugs, each wing having two members, an opening cut from the body of the ring for the free passage of the inner member of the wing, a shoulder bounding each side of the said opening against one of which shoulders the inner member of the wing is adapted to come in contact for limiting the tilting of the wing in one direction, a friction-band having a medial resilient looped portion cut from the body of the ring, a finger forming a part of each wing adapted to ride over the said looped portion, the inner member of the wing serving to limit the tilting of the wing in the opposite direction, substantially as set forth.

8. In a shade holder, a suitable shadeclamping wing comprising a pivotal axis, an

' outer actuating-arm, an inner deflected 1n ember adapted to seize the shade, and a tinger projecting inwardly, substantially as set forth.

In testimony whereof I ailix my signature in presence of two witnesses.
