ADJUSTABLE SHADE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 439,769, dated November 4, 1890.

Application lefl November 15, 1889, Serial No. 330,467. (No model.)

.To all whom t may concern.:

Be it known that I, JOSEPH E. BoHNER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Adjustable Lamp Shade Holders, of which the following is a specification.

In the type of shade-holders to which the present invention belongs, the holder, rings, or hoops are provided with suspension bars or rods hooked at their upper ends to engage over the top edge or rim of the lamp-chimney and furnish a suspension-support from such point for the holder and shade. In such holders, as heretofore constructed, no provision was made whereby the holder-ring could be adapted to support shades of any other than those having a uniform size or diameter of neck, and consequently different sizes of such holders were necessary to suit the various sizes of shade-necks found on the market 5 nor was any provision made whereby the holder could be adjusted vertically, so as to compensate for different heights of lamp chimney or shades, and so enable the position of the shade to be adjusted with relation to the iiame or light, so as to give the proper and requisite shading.

In the present improvement the above defects are avoided in a very perfect manner, and a shade-holder formed in which a ready and effective adjustment of the shade in a vertical direction can be eifected as well as the circumferential contraction or expansion of the holder ring or hoop in aV horizontal plane to fit any ordinary size or diameter of shade-neck.

The construction of shade-holder by which I attain the above result is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my improved shade-holder; Fig. 2, a detail sectional elevation illustrating the application of the same; Fig. 3, an enlarged detail horizontal section of the holder ring or hoop, illustrating the means for securing the ring ends together at the required circumferential adjustment;

of the means forV securing the ends of the holder ring or hoop together; Fig. 6, a detail elevation of one of the suspensiouarms, illustrating a modified means for vertically extending or contracting the same, so as to effect a vertical adjustment of the lamp-shade. Fig. 7 is a detail elevation, partly sectionized, of a modified form of the attachment of the shade-supporting arms to the holder-ring.

Similar letters of reference indicate like f adjustment may be effected by the spring or elasticity of the ring or hoop itself. I prefer, however, to employ a positive means to secure the ring at its required circumferential adjustment, and such positive attachment may be effected by providing one end of the ring or hoop with a series of perforations a and the other end with an inturned forwardly-projecting hook or tooth a' to engage in the proper one of said perforations to hold the ring to its required circumferential adjustment, as illustrated in Figs. l and 3, a rocking movement of said ends upon the tooth a as a fulcrum being prevented by an inturned lip a2 on the one end engaging in one of the perforations in the other end, as shown in Fig. 2. Again, one end of the ring or hoop may be formed with an elongated slot a3 to effect an attachment of the ends of the ring or hoop together, and, if desired, the attachment may be rendered more positive by forming the surface in contact with corrugations, as illustrated in Fig. 5. I do not, however, confine this part of my invention to either of said modes for attaining a positive IOO attachment, as any other well-known equivalent appliance maybe substituted therefor To enable the suspension-bars B being set d to, so as to enable the holder ring or hoop AY to be adjusted up or down with relation to the flame or light to compensate for different heights of lamp chimney or shades met with in the-market, and this vertical adjustment loetween the parts I prefer to accomplish in theffollowingmanner:

The lower ends of the suspension-bars R are made with corrugations B' and fit within a Vertical cavity or channel in the saddle or clip piece C, the outer wall of which cavity is formed'withcorrugations c, that correspond with the-corrugationson the end of the suspension-bar, so that the two will locktogether whenl brought in contact, and they are held in such condition by the holder ring or hoop A passing through the clip-piece back of the suspensionbar, asclearly illustrated inFigs. 2 and 3. With this construction the clipj piecel C is required to'be removed from the holder ring or hoop before an adjustment of the parts can'be effected. I do'not, however, limit thislpart of my invention to theabove meansfor effecting a relative adjustment between thev hooked ends of the suspensionarms and the holder ring or hoop, and any 'other'substitute means for the above may be employed instead without departing from the spirit of my invention. For instance, each of the suspension-bars can be made in two parts h2 bratftached together by a clip b4, in which engages the hook or tooth h6 on the other part,

as clearly'indicated in Fig. 6. At their upper ends the arms B are formed with upward ly-extending parts E to constitute a support above the chimney for a vessel for heating water, dro., as indicated in Fig. 3.

The supports or shoulders of the holder ring orhoop A, on which the shade rests and is supported, consist in the present invention`of aV series of arms D, hinged to the pendent ends'of the clip C, their body portion beingv curved outwardly to form outwardly-projecting rests or shoulders cl for the lampshade; whilev their free vor lower ends are curved inwardly to rest against the lampchimney. With this construction the weight of the lamp-shade will always force the free end of the arms Dinto contact with the sides of thelampchimney to afford afirm support for the lower end of the shade-holder and prevent wohblingof the shade and holder in use.

yI'n'the manufacture of my improved holder the arms D may be hinged directly to the holder ring or hoop A, independent of the clips C, without departing from the spirit of my invention, and in case where this hinged feature is -not required the ring orhoop A can be provided with any of the ordinary forms of iiXed arms or shoulders heretofore used, it being preferable in such cases that the arms form an integral part of the clip C.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A lamp-shade holder comprising a series of suspension-bars hooked at the upper end to engage over the top rim of the lampchimney, outwardly-projecting shade-supporting arms D, and a circular holder ring or hoop attached to the suspension-bars, andv formed with unattached ends, so as to be capable of circumferentialadjustment to fit different diameters of shade-necks, essentially as herein set forth.

2. A lamp-shade holder comprising a series of suspension-bars hooked at theirupper ends to engage over the top :rim of the lampchimney, a circular holder ring or hoop l formed with unattached ends, so: as to be capable of circumferential adjust-ment to lit different diameters of shade-necks, and clip= pieces C, securing the suspension-bars to the holder ring or hoop in a ci-rcumferentialljrd adjustable manner, essentially as herein deA scribed.

3. A lamp-shade-holder comprising al circular holder ring or hoop and aseriesof suspension-bars hooked at their upper ends to engage over the top rim of the `lamp-chimney, the ring or hoop being made adjustable in a verticalv direction with relation tothe hooked ends'of the suspension-arms, in the manner substantially as described, and for the purpose set forth. y

4. A lamp-shade holder comprising a series of suspension-bars hooked'at their upper ends to engage over the'top rim of the lampchimney, a holder ring or hoop formed with unattached ends, so as to be capable of circumferential adjustment to iit different di- ;ameters of shade-necks, and clip-piece C, slid- .ing on the ring or hoop and having vertical i channels to receive the lower ends of the suspension-arms, the ends of such arms and the outer walls of the'channels vbeing corrugated,

f and the holder-hoop arranged'to pass through the clip at the rear of the suspension-arms, essentially as set forth.

5. A lamp-shade holder comprising a series of suspension-bars hooked at their upper ends to engage over the top rim-of the lampchimney and a circular 'holder` ring or hoop attached thereto and formed with unattached ends, so as to be capable of circumferential adjustment to iit different diameters of the shade-necks, the one end being provided with a series of perforations a and at the other with an inturned forwardly-extending tooth a', essentially1 as set forth.

6. A lamp-shade holder comprising a series of suspension-bars hooked at their upper IIO IZO

ends to engage over the top rim of the lampchimney and a circular holder ring or hoop attached thereto and formed with unattached ends, so as to be capable of circumferential adjustment to fit different diameters of the shade-necks, the one end being provided with a series of perforations a and at the other an inturned forwardly-extending tooth a and an inturned lip a2, adapted to engage different perforations a, essentially as set forth.

7. A lamp-shade holder comprising a series of lsuspension-hars hooked at their upper ends to engage overV the top rimof the lamp-A chimney and extending upwardly to form projections E, that constitute a support for a Vessel for heating Water, ne., and a circular holder ring or hoop attached to said arms and formed with unattached ends, so as to be capable of circumferential adjustment to it different diameters of shade-necks, essentially as set forth. l
