PORTABLE ELECTRIC-LIGHT FIXTURE. 7
I Specification of Letters Patent. I Patented May 28,1912. Application filed October 13, 1910. Serial No. 586,887.
To all whom it may concern:
Be it known that I, LEROY A. WILLIAM- SUN, of Boston, county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Portable Electric-Light Fixtures; and I do hereby declare the following specification, taken in connection with the accompanying drawin s, forming a part of the same, to be a full, 0 car, and exact description thereof.
My inventlon relates to an improved form of portable electric light fixture of the same general character as the fixture forming the subject of my Letters Patent, No. 914,772, dated March 9, 1909. p I
It is the object of-the present invention to provide a form of portable electric light fixture which is extremely simple in construction and cheap to manufacture. a
To that end, the invention consists in the novel construction, arrangement and combination of parts hereina er described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a side elevation of my improved form of portable fixture showing the same in use. Fig. 2 is a similar view showing the fixture out of use and with one side verse sectional view through the center of Referring to the drawings, A represents the casing and B an attaching plug which is preferably made as a part of the casing. J ournaled in the walls of the casing A. is a hollow hub a, in which is a spring b..' The outer end of the spring I) is fastened to theis fastened to a stud d which passes throng the-hub a and is secured at eachend to t e walls of the casing. In the hub a is a transverse partition e which is provided upon one side with ratchet teeth 1 which are arranged and adapted to engage the teeth upona ratchet-wheel g WhlCh is splined u on the stud d. The stud dis provided wit a longitudinal slot h and surrounding said stud a coiled sprin i,'one end of which bears against the rate et-wheel g and the other end of which bearsagainst one ofthe walls of the casing A. Mounted to-slide longitudinall'y in the stud d is a in l, the inner end of which is connected to t e ratchet-wheel g. On one end of the hub a are two metal rings a which are in frictional enga ement with two metal rings a on the e of one of the wallsof' the casing A, The metal rings a are connected bya quantity of lamp cord 9'" wound on'the hub a to a lamp socket is, a
and the metal rings a are connected by wlres j to the plug B.
The operation of the device is as follows:
Remove the lamp from the stationary fixture and insert plug B into said fixture. Then draw lamp socket 7: out of casing A and insert the lamp taken'from the stationary fixture therein. Then draw as much of the cord y out of the casing as is desired. 'As
the cord is drawn from the casing the hub a will revolve and thereby wind up the spring b and when the desired amount of cord has been withdrawn the hub will be held against movement from the action of the spring by the ratchet wheel 9. When now the user has ceased using the device he simply pushes in the pm Z, thereby throwing the ratchetwheel out of engagement with the ratchetteeth f and the hub' a will be revolved by the spring I) in a direction to wind up'the cord and draw the socket is into the casing.
As soon as the socket is is partly or wholly within the casing,pressure is removed from the pin Z and the spring 71 will force the ratchet-wheel 9 back into contact with the ratchet-teeth f and the hub a will thus be locked against further revolution in a direction to wind up the cord.
What I claim as my invention and desire'to secure by Letters Patent is: e
1. In a device of the character described, the combination, with a suitable casing, of an attaching plug upon the exterior thereof, a hub mountedto revolve upon the interior of said casing, a quantity of electric lamp cord wound on said hub, a lamp socket attached to one end of said cord,means connecting the other end of said cord to the attaching plug, spring-actuated means for relamp socket on one end of said cord, and means connecting the other end of said cord to the attaching plug.
8. In a device of the character described, the combination, with a casing, of an attaching plug upon the exterior thereof, a hollow hub mounted to revolve within said casing; a spring arranged to revolve said hub, a transverse dpartition upon the interior of said hub provi ed with a series of ratchetteeth, a stationary stud extending through said hub, a ratchet-wheel mounted to slide on said stud and normally held in enga ement with said ratchet-teeth by means 0% a spring surrounding said stud between said ratchet-wheel and the casing, a pin slidably cord having one end mounted in said stud and having its inner end connected to said ratchet-wheel, two metal rings upon the exterior of said hub arranged to contact with two metal rings upon the interior of the casing, wires conmeeting the metal rings upon the casing with the attaching plug, and an electric light connected to the metal rings upon the hub and the other end connected to a lamp socket, said cord being arranged and adapted to be wound upon the revolving hub.
