A. L. BUSCHMAN PLURAL LAMP S OCKET Filed Jan. 10, 1925 Patented June 30, 1925.
UNITED STATES 'ABRAHAM L. BUSCHMAN, on NEW YORK, N; Y."
"PLURAL LAMP SOCKET.
Application filed January To all whom it concern;
Be it known that I, ABRAHAM L. Boson- MAN, a citizen'of the United States, res1d- York, have invented an Improvement in Plural Lamp Sockets, of which the. follow: ing is. a specification. p l v The present'invention relates to an improvement'in plural lamp sockets, one object being to reduce the number of parts and simplify manufacturing and assembling operations without detracting from;
the eifectiveness of the device for its intended purpose. I
One embodiment of my invention is illustrated in the accompanying drawings in which f Figure 1 is a central longitudinal section, Figure 2, a side elevation with parts broken away,
Figure 3, a detail View in perspective o'fl a-lamp receiving shell, and
Figure 4, a detail in perspective of an insulating washer.
The form 'of lamp socket shown in the drawings includes a base 1 of porcelain or other suitable insulating material, preferably capable of being formed when in a plastic, state. At one end of the base 1 is a plug 2, while theopposite end provides a housing' for connected shell "receiving recesses, 3 and 4. Passageways Sand 6 extendlongitudinally through the base from said recesses toward the plug 2, their exterior ends opening adjacent to the base of said plug.
A central opening 7 receives a bolt 8 which:
retains a contact or terminal washer 9 at its outer end and supports a twin contact piece 10 at its inner end. l
Each recess housesa threaded lamp re-- ceiving shell 11 which is preferably formed with a lamp receiving opening at oneend and a connector 12 at the other or inner end, said connector being integral with said .shell and made of materialpunched out or displaced from the normal contour ofthe walls'thereof.
The outer end of plug 2 is formed with a recess 13, cooperating with a cap 14 having a central opening and adapted to retain a threaded contact 15 in operative position on the plug 2.
In assembling, the shells 11 areinserted in their respective recesses with the connectors 12 extending through the passageways 5 and 6 respectively. The . free end 10, 19 25. Serial No. 1,545.
of'each connector isthen bent back. upon itself and over a detent or key 16 which (is preferably a flexible strip of metal such" ing in the city, county, and State of New.
as brass, and 'is positioned with its ends resting at either side of the outer end of the corresponding passageway, thus in ef-' form in effectconti'nuations of the passageways 5 and 6 respectively. When the free vends of the connectors 12 are bent over the keyslfiltow'ard the plug 2, the channels provide spacefto accommodate the extra thickness of metal thus produced at this point.
'After the connectors. are anchored or se-. cured in position as described, the threaded contact-15 is slipped down on the plug2 'and'into contact with the ends ofthe connectors 12 where it is secured in part by more firmly fixed inposition by applying a similar cement between their exterior surfaces and contiguousisurfaces of the recesses 3and 4. i i
The threaded contact 15 is further secured in operative position by means of the insulating cap 14 through which is passed the bolt 8. f Fiber'or other suitable insulating washers 18 are positioned in contact with the inner ends of the shells 11 being retained in place by means of the twin contact piece 10,.the respectivearms of which extend slots 19 in the washer 18.
From the foregoing description it will be apparent that my improved plural lamp .socket construction makes it possible to supthrough ..FT
ply an effective device for the intended fpur plicity make it possible'to produce ahigh grade fixture at a reasonable cost.
I claim as my invention:
1. In a plural lamp socket, the combination of an insulating base comprising a hollow portion having shell receiving recesses and a plug integral with said hollow portion, connector-receiving passageways in 65- molded in opposite'sides of the plug 2 and y said base each communicating with one of said recessesand extending therefrom toward-said plug, a threaded lamp receiving shell in eachrecess, a threaded contact on thelplug and a connector in each passage-.
way between said contact and each shell consisting; of an integral portion of said shell displaced from material forming a.
2. In a plural lamp socket, the combination' of an' insulating base having a plug at one end, interconnected shell receiving recesses at the other end, and connector receiving passageways each communicating with oneof' said recesses and extending therefrom toward said lamp receiving shell in eac recess, a threaded contact on the plug, and a connector in each passagewaybetween said contact and each shell consisting of an inte ral portion of said shell displaced from t e material -forming a wall thereof and, having itsfree end extending beyond theouter end ,of said passageway, and a detent vdisposed across ug, a threaded? said passa eway and engaging said free end 7 position. y
In testimony whereof, I have signed my to retain t e connector 1n contact engaging name to thisspecification this 2nd day of January, 1925. i
