Specification of Letters Patent.

' Application ma u mimr 1:, mo. Serial No. senses.

Patented July 25, 1911.

To all whom it may concern:

Be it known that I, Wrnnmm A. Harvey,- a citizen of the United States, and resident of Scranton, in the county of Laekawanna and State of Pennsylvania, have invented certain new and useful Improvements in specification.

This invention relates to a lamp which is portable in the sense that both the lamp and the source of electricity are self-contained and can be located at will at any desired place to be illuminated,- but which is nevertheless provided with controlling circuits and switches accessible from a remote point in order that the illumination may be established and extinguished prior to and after leaving the place of illumination; the lam being also preferably provided'with a loca switch by which it maybe cont-rolled at the lamp proper and also with a relatively movable independent lamp having its individual controlling switch and adapted to be moved about for directing illumination to points not reached by the definitely located main lam The invention will be fully understood upon reference to the accompanying drawings, in which,

Figures 1, 2, 3 and'4 illustrate the lamp proper without the external circuits, sai figures being, respectively, a front view, a side view partly in section, a top plan view, and a horizontal section. Figs. 5 and 6 represent by vertical section and by rear view on an enlarged scale, the reflector and support for the bulb of the located lamp. Fig. 7 is a sectional view of the insulating mounting for the binding posts and the local switch of the located lamp. Fig. 8 is a detail view of the remote switch. Fig. 9 is a section on the line 9-9, Fig. 8. Fig. 10 is a schematic view of the located lamp, the local and remote switches therefor, of the relatively movable lamp and its switch and of the common source of current, and Fig. 11 is a detail view of the combined cell embracer and-spacer.

1 represents the main lamp, which it is desired to adapt not only for locating in a place where electric eqllaiipment is not already present, but whic also is desired to be portable, for which reasons the lamp is constructed in the form of a suitable receprounded by a suitable reflector 3, carrying handle 4 and a suspending handle 5 preferably located so that the lamp may be hung overhead.

. The rece tacle 1 contains a suitable source of electricity preferably embodied in dry cells '6 and 7, or '6 and 7. The reflector 3 forms a 'reentrant wall of the receptacle 1, :and thus acts as a separator for the cells 7. If a single cell 6 is used, it lies between the :cells 7 in a manner to cod rate with the re- Hector 3, keeping the ce ls 7 spaced a art and said cell 6 is in turn embraced and eld in place by a resilient cradle or seat 8. But if two rear cells 6 are employed along with the front cells 7 they abut against the front .cells 7 to holdthem in place and are themselves spaced apart and held against lateral displacement by means of a cell spacer 8', introduced between them (see dotted lines Fig. 4). For conveniently adapting the re- =ceptacle to thus receive and pro erl hold either three or four cells, atwi l, t e em- 'bracer 8 and s acer 8 are provided in a sin- ,gle structure Fsee Fig. 11) and made to extend at right angles to each other so that when hinged tothe wall of the receptacle by bearing straps such as 8", the device may be :swung through an arc of 90 to bring either the embracer or the spacer into position of use; either of the parts lying against the wall when the other part is in position of use, and thereby preventing its displacement. The bulb or socket 2 is supported by .a vertical bar 9 of insulating material supported by brackets 10 attached above and below the reflector 3, thereby providin a laterally reduced support for the soc et, which avoids infringing upon the battery space and afi'ords rigid support for the socket.

For suitably connecting the lead wires from the battery and the lamp among themselves and with the external circuits, binding posts 11 and 12 are mounted upon the insulating plates 13, 14, on the top wall 29 0f the lam receptacle. Binding post 11 is connected y wire 15 with one pole of the battery 6, 7, which is in turn connected by wire 16 with one pole of the lamp 2, while the other ole of the lamp is connected by wire 17 with the binding post 12. A third bindin post 18 is connected with the battery wire 16 in order to ada t the terminals for the attachment of an in ependent external cireuit 19, 20, for feeding a relatively movable lamp 21; which may be controlled by an independent switch 22.

The main lamp is controlled either'by a local switch 23 which may be provided by the setscrew 23 and spring tongue 23", or said main lamp may be controlled through an exterior circuit 24, 25 leading from a remoteqswitch 26.

Switch 26 is preferably constructed of a relatively long resilient contact 27 having an arm 27 extending transversely toward and. downwardly to a plane beneath the swinging switch arm 28 which is thereby adapted to ride up on the arm 27. This provides a very cheap and eflicient and very durable switch, which may be held in the hand or hung or laid about in any convenient position. The mounting for this switch 26 comprises a suitable base 526 and a cover plate 26 both of insulating material. The cover of the receptacle is represented at 29, preferably constructed with down-turned flanges fitting over the main body of the receptacle and connected therewith throu h a stud 29 and a screw 29. The u per e ges of the sidewalls of the receptac e are provided with inturned flanges 1 to stiffen the walls and receive the cover. The interior of the receptacle is preferably lined throughout with an insulatm material 1".

A combined portabIe and hanging electric lamp of the character described with its 10- cal and remote controlling switches, affords a verycheap and convenient means of illuminating dark places not permanently equipped with connections for electric or other lights, and the provision of the extension or relatively movable lamp circuitgreatly increases the range of use for a device of this kind, in that it permits illumination of dark corners or adjacent compartment's.

I claim 1. An electric lamp comprising a suitable receptacle having a reflector providing a reentrant wall and batteries contained within the receptacle and spaced apart by said reentrant wall.
