Specification of Letters Patent.
Patented Aug. 9, 1921.
Application filed October 25, 1919. Serial No. 339,385.
T 0 all whom it concern:
Be it known that I, Jo ns ANDREW Mo- KAY, a subject of the King of Great Britain, and resident of New York city, in thecounty of New York and State of New York, have invented certain new and useful Improvements in Electrical-Fittings Connections, of which the following is a specification.
The present invention relates to electrical fixtures connections and is more particularly an improvement on the structures shown in Letters Patent Nos. 1,300,286 and 1,307,869, and being a continuation in part of my application Serial No. 242,915, filed July 1, 1918. In the two patents aforesaid are disclosed fitting having an inclined socket member and a removable fitting having a pivotally supported terminal member engaging the socket member. By the construction there shown practically the entire load of the removable fitting including the canopy and fixture is sustained by the contact members of the two fittings. The present invention is especially useful where the parts are heavy or the suspension takes place from above, although it has a universal adaptation in the class covered by the invention. The present invention, therefore, provides means independent of the electrical contacts for sustaining the load of the parts without sacrificing any of the advantages of the construction shown in said patents.
In the accompanying drawings the invention is disclosed in several concrete and preferred forms in which Figure 1 is a longitudinal sectional view, showing one form of the invention:
Fig. 2 is a sectional view on the line 2- 2 of Fig. 1:
3 is a sectional detail view on the line 3-3 of Fig. 2:
Fig. 4 is a perspective view of the terminal member carried by the removable fitting, partly broken away and in section:
Fig. 5 is a longitudinal sectional view of a modified form of permanent fitting embodying the invention:
Fig. 6 is a view partly in elevation and partly in section of the permanent fitting shown in Fig. 5 and its complementary removable fitting:
Fig. 7 is a sectional view on the line 77 of Fig. 6:
Fig. 8 is a sectional view on the line 8-8 of Fig. 6:
Fig. 9 is a sectional view on the line 99 of Fig. 6.
Referring to the form of the invention shown in Figs. 1 to l inclusive, 1 is a ceilmg box that constitutes, together with its appurtenant parts, the permanent fitting. This fitting, as here shown, is essentially characterized by a socket member or block 2 of insulating material recessed to receive socket contacts 3 secured by means of screw 4 and having each a binding post 5. 6 indicates the leads, from the source of power, that are connected to binding posts 5. Block 2 is suitably sheathed, as at 7, and is provided with supporting guides 8 that are substantially parallel to the ceiling from which the fixture is suspended. 9 is the removable fitting consisting here of a carrying member 10 having side walls 11 arid guides 12. Pivotally mounted by trunnions 13 extending into side walls 11 is a terminal member 14; of insulating material provided with contacts 15. The carrying member also supports bushing 16 for a fixture (not shown) and wires 17 extending from contacts 15 through said bushing to the fixture.
The fittings are brought together by slidingly engaging guides 8 of block 2 and guides 12 of terminal member 9, contacts 15 at the same time entering socket contacts In this manner, the weight of the fixture is sustained by the slidingly engaging guides rather than by electrical contacts. 18 indicates a spring latch carried by block 2 that snaps in behind terminal member 14 and locks the parts in position.
In the modifications shown in Figs. 5 to 9 inclusive, 19 is a wall or ceiling box which, together with its appurtenant parts, constitutes the permanent fitting located in wall or ceiling 20 and substantiallyfiush with the surface thereof. This fitting is characterized by a socket member 21 of insulating material pivoted at 22 and normally held in closed position flush with the wall or ceiling by means of spring 23. When in its closed position, knife blades 2d are out of engagement with contacts 25 to which the leads 26 are connected. When, however, it is desired to attach a fixture to the fitting, socket member 21 is swung around its pivot 22 and brought into an inclined position that causes it to protrude from the wall. Socket member 21 has sockets 32 connected to blades 24 is a terminal member of insulating material having contacts 31 to which wiring 33 from the fixture is suitably connected. Terminal member 30 is provided with trunnions 34 extending into slots 35 of fitting 28 so as to mount it pivotally and slidingly therein,
said fitting being provided with guides 36 complementary to guide 27. I
The fittings are brought together by bringing guides 36 into sliding engagement with guides 27, contacts 31 at the same time entering sockets 32. A set screw 37 carried by fitting 28 is used to lock the two fittings together by having it enter an aperture 38 in the socket member.
I claim:
1. An electric fixture connection comprising: a permanent fitting having a socket member comprising electrical contacts connected with the feed wires, a removable fitting, complementary guides on said fittings independent of the contacts and slidingly ens gaged to support the removable from the permanent fitting, and a pivotally mounted terminal member carried by the removable fitting engaging the socket member when the two fittings are slidingly engaged.
2. An electric fixture connection comprising: a permanent fitting having an inclined socket member comprising electrical contacts connected with the feed wires, a removable fitting, complementary straight guides on said fittings independent of the contacts and slidingly engaged to support the removable from the permanent fitting, and a pivotally mountedterminal member carried by the removable fitting engaging the socket member when the two fittings are slidingly engaged.
3. An electric fixture connection comprising: a permanent fitting having an inclined socket member comprising electrical contacts connected with the feed wires, a removable fitting, complementary straight guides on said fittings independent of the contacts and slidingly engaged to support the removable from the permanent fitting, and a slidingly and pivotally mounted terminal member carried by the removable fitting engaging the socket member when the two fittings are slidingly engaged.
4e. An electric fixture connection comprising: a permanent fitting, a socket member pivotally mounted on said fitting to occupy a position substantially flush with the surface in which the fitting is located or a position inclined thereto, supporting guides on said socket member occupying a position substantially parallel to the surface aforesaid when the socket member is in its inclined po sition, a removable fitting, guides insaid removable fitting to slidingly engage the guide on the socket member, and a pivotally mounted terminal member carried by the removable fitting engaging the socket memher when the two fittings are slidingly engaged. V
5. An electric fixture connection compris ing: a permanent fitting, a, socket member pivotally mounted on said fitting to occupy a position substantially flush with the surface in which the fitting is located or a position inclined thereto, supporting guides on said socket member occupying a position substantially parallel to the surface aforesaid when the socket member is in its inclined position, a removable fitting, guides in said removable fitting to slidingly engage the guide on the socket member, and a slidingly and pivotally mounted terminal member carried by the removable fitting engaging the socket member when the two fittings are slidingly engaged. I
6. An electrical fixture connection comprising: a permanent fitting having a socket member with electrical contacts, a removable fitting, complementary guides on said fittings independent of the contacts and slid ingly engaged to support the removable from the permanent fitting, a pivotally mounted terminal member carried by the removable fitting and engageable with the socket member, and means for locking said fittings together.
Signed at New York city, in the county of New York and State of NewYork, this 7 22nd day of October, A. D. 1919.
