EDWARD A. JARVIS, OF WEST NEW BRIGHTON, NEW YORK.

PARKING-LAMP.

To all whom it may concern i Be it known that I, Enwann A. Janvls. a citizen of the United States, residing at 'lVest New Brighton, county of Richmond,

State of New York, have invented certain new and useful Improvements in Parking- Lamps, of which the following is a full, clear and exact descnption.

This invention relates to improvements in parking lamps for automobiles; in other words. lamps used while'automobiles are i parked in lieu of the head and tail lights, thereby savmg considerable battery energy.

- "'Qne of the objects of my invention is to produce a combined electric parking lamp,

[that is to say, a lamp showing red from the rear and white from the front, and a movable mirror, the mirror to be used for dayred lens 11.

light driving to observe those behind, to

'gether with means to complete theci'rcult for a bulb, within the lamp, when the mirror is moved out of alinement with the lam when the lamp is to be used. Referring to the accompanying drawmg:

Figure 1 illustrates a vertical sectional view of a lamp embodying my improve-- ments;

Fig. 2 is an enlarged sectional view, the section being taken on a line 2--2 in Fig. 1;

Fig. 3 is a fragmentary vertical sectional view, the section being taken on a line 33 in Fig. 2;

Fig. 4 is a sectional view, the sectionbeing taken on a line 4-4 in Fig. 1;

Fig. 5 is a fragmentary vertical sectional view, the section being taken on a line 5-5 in Fig. 1;

Fig. 6 is a sectional plan view, the section being taken on a line 6-6 in Fig. 5; and

Fig 7 is a modified form of the switch portion of my invention.

As herein embodied. the lamp consists of a base 8 carrying a split expansible shell 9 to hold a front white lens It) and a rear The lenses 10 and 11' are held in annular channels 12 in said shell. The shell 2') at one end is rigidly secured to the base by a rivet 13 (in this instance), the other end being slotted as at l4 to straddle a clamping bolt 15, which passes loosely Specification of Letters Patent.

secured in clamped position by tightening the bolt 15. To remove the lenses, bolt 15 will be loosened and the shell spread open sufliciently to allow the lenses to be taken out. Theslot 14 permits the shell'to be spread. As can be seen. the base 8 is hollow and at its upper end supports a socket is for the bulb 15); The socket may be. secured in'place by molding, as indicated at 20, or otherwise. The mirror 21 is adjustablysecured to ahinge block :22 which in turn is pivotaily secured to the base 8: in this-instancel have pnovided ears 23, 2- between which the hinge block is located. In this instance, the mirror carries a brace 24 hav ing an arcuate extension 25 having a slot 26 for the passage of a locking bolt 27. said bolt engaging the block 522. The upper end of brace 24 carries a projection or keeper 2R having an opening therein to be engaged by,

a teat 29 carried by a latch 30 supported by the shell 9. The. radial point of the curved projection 25 will be located at about the point of contact of the upper surface of the keeper 29 and latch 30: hence said mirror can be adjusted toward or away from the lamp when bolt 27 is loosened. without interfering with the engagement of thelatch and keeper 29. As the axis of the bolt 27 is in alinement with the axis of the teat 29, the mirror'can be adjusted in a vertical plane'without interfering with the engagement of the latch and keeper. It will be apparent that the mirror is adjustable in a vertical plane as well as toward'or away from the lamp. Tn this instance, the base 8 carries a threaded nipple 31 to be engaged Patented Feb. 15, 1921. Application filed April 26, 1920. Serial no. 376.438.

to automatically close the circuit for the bulb 19 when the mirror is moved out of alinement with the lamp, when said lamp is to be used (see dotted lines in Fig.- 1). To this end I provide a switch operable when the mirror is moved down; in' this instance when lowered all the way. down.

block 22. As herein embodied the switch consists of a block of insulating material 34 carried by the base 8 and contacts 35 and 36, the contact 36 being movable and passing freely through the block. To place the contact 36 incircuit with the bulb, I provide I As herein illustrated the switch 15 operated by the hinge ductor having connected thereto one end of a second Wire 35}. The wires 38 and 39 will be connected to a source of e ectrical energy or battery 40 for vehicles having a two wire circuit. For a. one Wire or ground circuit (see dotted lines 41, Fig. 1), the Wire 39 will not be connected, as the base 8 will be a part of the circuit. When the mirror is lowered the hinge block-22 Will bridge the contacts 35 and 36 and the lamp will burn. Whether the circuit is two Wire or ground,

the yieldability of the rod will lend Sui? ficient spring action to the contact 36 to I maintain same in firm contact with the hinge block. When not in use the outer end of contact 36Will extend slightly beyond the outer end of contact 35. Instead of employ ing the contacts and 36,1 inayuse a single movable contact 42 in Fig. 7, Which-passes through a metal tube 43 but insulated therefrom by a bushing 44. The metal tube will have connected thereto one endof a circuit Wire 45. When contact 42 is forced in, the head 46 will contact with tube 43 thereby completing the circuit,fo1 the bulb. The contact 42 engagesthe rod 47 carried by the socket 48, the same as contact. 36 engages rod 37. The opposite circuit wire is indi cated by 49. The insulating block as may be held in place by means of a screw 50 (see lt will also be apparent that themirror can be adjustedWithout affecting the hinge block; hence, the switch and hinge block will always cooperate to close the circuit regardless of the'position of the mirror relative to the lamp, The Weight of the mirror will maintain the hinge block in contact with the switch contacts. I

Havmg described my invention, What i claim is 1. A casing for electric lamps, consistine;

of a split shell member, an annular channel at each edge thereof to releasahly engage a lens, a support, means to secure the shell at one end to said support and means to slidably connect the other end of said shellto said support.

2. A. signal device having a White front lens, a red rear lens, a mirror inovably mounted adjacent the signal device and nor mally concealing the red lens, an electric lamp to illuminate the red and white lenses,

an open circuit therefor, and means associ ated with the mirror to close the said circuit when the mirror 18 moved to expose the red lens.
