`This invention relates to electrical fittings for floor outlets. Floor outlets are made to extend a few inches above the floor, and in its proper relation to the upright tubular support, and protect it from injury.
Another ob'ect is to unite the metalliccover -of the tting to the tubular Yupright with a sleeve by engaging'means that will act a's a clamp holding the fitting securely onto the top of the upright.
A further object is to utilize the sleeve in Aconnection with a bifurcated fitting cover turning when the sleeve is turned.
A further object is to provide accessibility to the binding posts of the fitting by a lowering of the sleeve without disturbing the relation of the other members.
Other objects will appear from the following description of an embodiment of the invention, in connection With the accom panying drawings, in which Figure 1 is a vertical section and side view of a floor outlet.
Figure 2 is a section and side View onl the line 2-2 of Figure 1.
Figure 3 is a'perspective viev7 of one half of the cover casing.
Figure 4 is a perspective view of the tubular riser or upright.
Figure 5 is'an axial section of a modification.
Figure 6 is a section in side View, at right angles to the view of Figure 5., f
A conduit as shown at 1 is laid under a floor 2, and has at various points uprights or risers 3 which are in the forni of short nipples that are screwed or otherwise secured to the underfioor conduit 1, and rise for a distance of a few inches above the floor. The riser 3 is preferably made with a collar or flange 4 at the upperend (see Figure 4). At 5 is shown a T-shaped insulating fitting which 'may be in the form shown in Figures 1 and 2, where the upper portions are provided with receptacles for terminal jacks, as shown at 6, with depending binding posts 7 that reach down into the hollow lower legs S of the fitting, or as .shown in Figure 5, the fitting 5a may be a plain T with vertical and horizontal openings through which wires maybe led from the underfloor conduit out into the open. These fittings are preferably made invtwo halves split on a vertical median plane, alignment being secured by havingtheir contacting surfaces provided with corresponding dowels and sockets.` At 9 are shown thel two halves of the verticallydivided T-shaped metallic housing or casing. These housing .parts are shaped as shown in Figure 3,' and are characterized by an interior horizontal wall that closely fits the exterior contour of the insulating fitting. while the lower part 10 is formed with a screw-thread on its outer periphery which is adapted to engage with an internal screwthread'on a metallic sleeve 11, which has at 11a an inturned flange, to engagekbeneath the iange 4 of riser 3, these flanges forming interlockin means between the sleeve and housing. he lower end of the fitting rests upon the upper end of the riser, and is drawn into close contact therewith by the engage- `ment of flanges 4 and 11a on the tightening of the screw-threads on 10 and 11. To prevent the fitting from turning when the sleeve 11 is turned, interlocking means are provided between the iitting and the riser, which, in the example shown, takes the form of projections l2 on the fitting, and slots 13 on the riser. A screw 141: in the upper end of the housing 9 may he used to hold. the two parts of the housing together, and the halhousings are further clamped together by vthe collar l1 when screwed into position. The collar 11 is made to screw up against a shoulder on the lower part o'l2 the housing 9 when the parts are in clamped together pothat has the binding posts 7, are provided with openings 15 through which access may be had to the binding posts for the-making of electrical connections when the sleeve, ll is lowered. To allow full vertical ampli! (nde to the openingsl, theymayextend above the lower edge of the housing as shown, the lower screw-threaded end of the housing being notched to expose the full height of said o enings. It will be noticed that the,l fitting 1s in its yfinal osition when such connections are made, t e subsequent, screwing on of the sleeve not affecting in any way the osition of-the fitting.
While in tiie embodiment shown, screwthreads and collars or flanges have been mentioned as means of engaging the collar ll with the casing 9 and the riser 3, it is to be understood that other well-known equivalents may be used instead.
l. An outlet fioor riser comprising in combination, a tubular supporting member, a sleeve slidably mounted on the supporting member, interlocking means between the sleeve and the supporting member, a metallic casino* divided vertically into two halves and having lower portions adapted to engage the sleeve and be .held together thereby, and an insulating fitting between the two halves of the said casing and clamped in position by the engaging of the lowe'l` portion of the casing with the sleeve.
2; An outlet Hoor riser comprising in combination, a tubular supporting member, an
` internal threaded sleeve slidably mounted on the supporting member, interlocking means between the sleeve and the supporting member, a metallic casin divided vertically into two halves and aving screwthreaded lower portions adapted to engage the screw-threads of the -sleeve and be held together thereby, and an insulating fitting between the two halves of the said casing and held in position by the tightening of the screw sleeve on the screw extensions of the casing. 3. An outlet floor riser comprising in combination, a metallic tubular supporting member having a lcollar at its upper edge, an interiorly screw-threaded sleeve slidably mounted on the supporting member 'having a collar engaging the collar on the said'snpporting member, a metallic casing divided vertically into two halves and 4having screwthreaded lower portions adapted to engage the screw-thread of the sleeve and be held landau insulating fittingI h dbetweenjthe two halves of the said casingandnadapted to Abe clamped against the upper edge of thesaid support by the tighty:-
ening of the screw sleeve on the screw exten sions of the casing.-
sleeve slidably mounted on thecsupporting.1
member, mterlocking means between the sleeve and the supporting member, a metallic casing divided vertically into two halves and having lower portions adapted to engage the sleeve :and `be held together thereby, and an insulating fitting between the two halves of the said casing and held in position by the engaging of the lower portion of the cas` ing with the sleeve, the said'fitting and the said supporting member interlocking to pre-` vent the turning of the fitting relative to. the support.
5. An'ontletriser comprising in combination, a metallic tubular support, a sleeve slidably mounted on :the support, a vertically divided metallic" casing, a T fitting of insu` lating material clamped between the two halves of the casing and extending down to the support, means on the sleevecooperating with means on. thecasing and on the support to clamp the fitting between the casing and the support.
6. A11 outlet riser comprising in combination, a metallic tubular support, a sleeve slidably' mounted on the support, a, vertically divided metallic casing, a'T fittingof insulating material clamped between the two halves of the casing and extending down toy the support, means on the sleeve cooperating with means on the casing and on the snpport to clamp the fitting between the casing and the support, with means on the upper end of the support and lower end of the fitting for preventing the turning of the fitting.
7. An outlet riser comprising in combination, a metallic tubular support,'fjal sleeve slidably mounted on the support, a vertically,
divided metallic casing, a T fitting of insulating material clamped between the two halves of the casing, and extending down to the support, means on the sleeve cooperating with means on the casing and on the support to clamp the fitting between the-casing and the support, the lower end of the fitting having binding posts' and side openings in the zone'of the sleeve for access to the binding posts.
