Appneation ined :rune 19, 1925. serieu No. 38,247.

This invention relates to electric ixtu'res or brackets, upright or horizontal; and has special reference to adjusting and securing ineens ior such iixtures'or brackets.

(hie object of the invention is to improve the general construction ot 'devices of this character.

A second object of the invention is to provide improved clamping means for securing such bells in vertically adjusted position on its shaft or tube.

ln the equipnient of homes with electric lighting .fixtures it is common to use ceiling bells or rosettes and it frequently happens that the pipe, used as a conduit for the lamp wires, loosens at its connection with the conduit in the ceiling or that the light bell twists and loosens on such pipe. At other 'times the ceiling bell loosens on the pipe.

fr third object of the invention is to proride an improved construction of these parts "ich that the ceiling and light bells are firmly xed on the pipe.

lilith the above and other objects in View as will be hereinafter apparent, the invention consists in general of certain novel details o1C construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifr cally claimed.

ln the accompanying drawings like characiers of reference indicate like parts in the sereral views, and:

Figure 1 is a vertical median section through a bell showing the same supported on a pipe in accordance with the present invention. y

Figure shows a modified view of the adjusting clamp.

Figure shows a detail at right angles to Figure 1 and disclosing the clamps in a second modification.

Figure is an enlarged plan view o1 the clamp in the form shown in Figure l, the pipe being` shown in dotted lines.

Fi `ure 5 is a section on the line 5-5 of igure l.

Figure 6 is a bottom plan View showing one member of the clamp as disclosed in Figure 1.

Figure 7 is an enlarged bottom plan view ol the modification shown in Figure 3.

Figure S is an enlarged detail side view the clamp 'shown in Figure 3. Figure 9 is a section through alight and ceiling bell showing the manner of securing the parts together.

Figure 10 is a side elevation thereof.

Figure 11 is a sideelevation showing the manner of using the device.

ln the present disclosure ot the invention there is shown in Figures 1' to 8 a bell 10 which may be of any desired shape. This bell is mounted for vertical sliding movement on a pipe 11. The bell, as is common in such articles, is formed by a suitable pressingl or spinning operation and is provided with a centrally disposedaperture through which the pipe passes, the bell being ireely slidable on the pipe unless restrained by suitable clamping means.

in each of the instances here shown the peculiar' clamping means employed consists off a sleeve 12 slidably mounted on the pipe 11 and provided, intermediate its ends with a flange or collar 13, the aperture in the bell being of proper size to enable it to fit over the upper end of the sleeve and have the portions of the bell surrounding the aperture rest on said collar. The upper end of the sleeve, above the collar is threaded so that a nut 1st having a flange 15 may be screwed thereon and thus clamp the bell between the flanges 18 and 15. By reason of this construction, the sleeve, nut and bell move on the pipe as a unit.

In the forms shown in Figures 1, 2, t and 5 it will be seen that the sleeve 12 is generally of cylindrical cross section, but is provided with an angularly disposed oliset portion 1G which has, in one of its sides, a threaded opening for the reception of a set screw 17 which may extend through the side ot the bell, as shown in Figure 1, or may have an angular head 18, as shown in Figure 2. In the first case, see Figure 1, the set screw is operated by an ordinary screw driver, while in the second case, see Figure 2, a suitable wrench is applied thereto from within the bell. In the other form of the device the lower part of the sleeve is split to provide arms 19 and a contractile portion separated from the nut by a slot 20. These arms may be drawn together by a screw 21.

In each case it will be observed that the sleeve and belt together with the nut may slide freely on the two until the screwv is tightened up. It is to be noted that the arrangement shown in Figures l, 4 and 5 is such as to make the screw bite eccentrically into the pipe. It is important in devices of this character that the pipe support is not deformed because such deformation would prevent adjustment of the sleeve on the pipe. Accordingly, the eccentric arrangement of the set screw 17 gives a proper grip between the sleeve and the pipe without forcing the pipe wall inwardly, as would be the case if such pressure was exerted on a radially disposed screw. ,Correspondingly in the forms shown in the Figures 7 and 8, the grip is obtained around the pipe,j thus avoiding a deformation.

It will be obvious that whatever the length of the pipe 11, the bell, its sleeve and nut may be adjusted vertically of such pipe and there held by proper operation of the screw.

In Figures 9 and l() it will be seenthat there is provided a ceiling bell 22 which is connected to the bell 10 by a pipe ll. The clamps being like those previously described. Thus, by clamping these two bells in adjusted position the device becomes a practical unity and all twisting of wires by loose joints between the bells is prevented.

It will be obvious that the bell may be applied to the clamp by stamping or forcing the bell into position on said clamp, or it may be brazed or soldered thereto.

There has thus been provided a simple and efficient device of the kind described and for the purpose specified.

It is obvious that minorchanges may be made in the forms and construction of thel invention without departing from the Inaterial spirit thereof. It is not, therefore, desired to confine the invention, to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new is:

l In combination, a pipe hanger for lamps, a sleeve slidable on said pipe hanger, a bell carried by and enclosing a portion of said sleeve, and a clamping screw carried by the sleeve within the bell to clamp the same in adjusted position on the pipe, said clamping screw extending through the sleeve in eccentric relation to the pipe whereby to bite into the pipe at one edge of the screw, said bell being provided with an opening aligned with said screw to permit manipulation of the screw from the exterior of the bell.

In testimony whereof I affix my signature.

JACOB B. BANDER.
