G. FREAD ELECTRIC LIGHTING FIXTURE Filed Feb. 4, 1926 INVENTOR Patented Aug. 14, 1928.
UNITED STATES PATENT OFFICE.
GUY FREAD, OF ENID, OKLAHOMA, ASSIGNOR F ONE-HALF TO JOHN MAINLEY, OF
ENID, OKLAHOMA.
ELECTRIC-LIGHTIN G FIXTURE.
Application filed February 4, 1926. Serial No. 86,055.
This invention relates to a device for holding electric light bulbs in a. fixed contact position, when the structure of the fix ture is subjected to vibration, as, for instance, in the head lights of automobiles, as
Well in many places Where electric lights are used in moving amusement devices, railway equipment, and so forth.
Other objects of the invention will appear from the detail description containedin this specification, and by reference to the sheet of drawings accompanying the same.
Figure 1 is an elevational view of the structure,
Figure 2 is a similar View, only partly in section, and V Figure 3 is an enlarged view of the yield in g contact holding member.
Looking to the drawings, an internally tapering housing 4:, is provided with a slot 5, and a flexible tongue 6, the inner face of which frictionally engages, and thus controls the movement of the base 7 of the electric light bulb 8, in addition to the control it receives from the studs 9 that take into the usual slots (not shown) commonly provided in the housing 4.
Insertable into this tapering housing 4:, is a corresponding tapering member 10, axially bored throughout to receive a sleeve 11, slotted at 12, and also a core 13 for the reception of the feed Wire to be held by the set screw 14. V
Yieldably mounted in this sleeve 11 is a contact 15 having radial studs 16 moving in and controlled by the slots 12, and urged forward to a limited movement by a spring 17, the dew of current from the Wire, not shown, being through the member 10, the spring 17 and into the contact 15.
This spring not only seeks to determine a contact between the contact 15 and the conclaim tact block 18 on the base 7 of the electric light bulb, but that block being held against axial movement by the studs 9 in the key slots, also acts as an abutment against which the contact bears, and causes the spring 17 to force the member 10 which is provided with a tapering Wall, corresponding to the internal tapering bore of the housing 4, to find a permanent lodgment in the taper, and prevent disassemblage 0t parts due to shock or vibration.
Thus it Will be seen that there is provided a highly efiicicnt and practical device of the 5" kind set forth and possessing a utility and eiiicicncy, especially desirable for the pur poses for which it is intended Having thus set forth the invention, I
In an eletric light fixture oi? the class described, the combination with a tubular housing having a tapered core and means for securing a light base therein; of a tapering block member :litted in said housing and pror jecting from the rear end thereof, said block member having a central bore, a removable core fitting in the rear endot the bore of said block member, means for securing said core in position, a guide sleeve titted in the forward end of the bore of said block member having longitudinal slots therein opposed diametrically, an elongated contact member slidably mounted in said guide sleeve, lateral. lugs on said contact member projecting in said slots and spring means between the rear end of said contact member and said core, as and for the purposes described.
In Witness whereof I have this Q'ith day of January, in the year of our Lord, nineteen hundred and tiventysix,signed my name at Enid, in the county of Garfield and State of Oklahoma.
GUY FREAD.
