siGNAr. LAMP.
Application filed. a... 24," 1922. Serial No. 570,670.
To all whom it mwyooncemr Be it known that I, Cnanms E. GODLEY, a citizen of the United States, and residing at Detroit, in the county of Wayne and 6 State of Michigan, have invented a new and Improved Signal Lamp, of which the following is a specification.
This invention relates to the construction of a lam for the rear-ends of motor ve- 10 hicles an its object is to provide a simple and efiective combined tail-lamp and rear signal lamp which can be made at low cost, and which may be used to illuminate the roadway, rearwardly and laterally, of the 15 vehicle. V
In the accompanying drawing Fig. 1 is a front elevation of this improved signal lamp. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a section on the line 20 3-3 of Fig. 2. Fig. 4 is a plan of an insert which constitutes the separate compartment for the-signal lamp Fig. 5 is a section on the line 5-5 of ig. 1. Fi 6 is a bottom plan of a connector lug. ig. 7 .is 25 a section on the line 77 Fig. 3.
' Similar reference characters refer to like parts throughout the several views.
The body of this lamp has a back 1, sides 2, and 3 which merge into the semi-cylindrical top 4 and bottom 5. The front edge of the body is bent out to form the flange 6 which ends in an end 7 parallel to the sides, top and bottom of the body. The lamp may be attached to an desired bracket or support by means of b0 ts 8 mounted in the back 1. An openlng .9 may be cut in the bottom to permit light to fall on a license plate, this opening bein by a small sheet 10 of celluloid Wl'llCh is held in position by the ears 11. V
A cylindrical insert consisting of the shell 14, back and front flange 16 may be mounted in the upper part of the body, the body and the insert having inter-engaging ribs 17 and 18 respectively. The flange 16 may be formed with a groove to receive the packing cord 19 a inst which the lens 20 is pressed by the oor, the cord preventing entrance of dust and also preventing the lens from rattling.
Mounted on the lower portion of the shell 14 is a connector tube 22 formed with bayonet slots 23 to receive the pins 24 on the covered bases 25 of the light bulbs 26 and 27. The
two bases have central projections 28 adapted to be engaged by the spring contacts 29 carried by an insulatin plug 30. These contacts have transverse y corrugated ends 31, or are otherwise deformed to receive these projections 28 and are thereby held in position. A short thimble 33 is attached to the side of the body at' an opening therein to receive this plu and the thimble is preferably formed wit a rib 34 adapted to enter the groove 35 in this plug to insure the plug being inserted properly. The con nector tube 22 is referably lined with a shell 36 of insulating material to prevent the contacts 29 from touching the sleeve. The bases of the lamp bulbs are grounded on this sleeve. i
The ange 6 on t e body below the insert is also grooved to recelve the packing cord 43 against which the lens 44 is held by the cover. The upper lens 20 is preferablycircular while the upper part of the lower lens is cutaway to fit the upper lens. The lower lens is preferably convex outward as shown in Fig. 2. The cover or door is formed with a flange 45 to fit around the edge 7 of the body and with an inwardly curved edge 46 to engage the two lenses. It also comprises a preferably semi-cylindrical cross piece 47 which extends over the adjacent ed es of the two lenses. I
y desired means may be employed to. secure the cover in position. I prefer to bulge out the sides 2 and 3 and secure nuts 48 n the spaces thus formed by soldering or welding, which nuts are adapted to receive the screws 49 which extend through the cover. y
Referring now to the insert it will be noticed that its shell 14 is formed with two 7 inclined to the axis of the shell 14 that the reflector 53 will project the light downward and laterally of the line. of the vehicle. It is usually desirable to illuminate the roadway at the left of the vehicle when that is being backed and for this reason I prefer to have the reflector mounted in the manner shown in Figs. 2 and 4;.
The switch mechanism for these lamp bulbs may be of any well known construction and none is therefore shown. Any well known switch may be connected into the circuit to the lower light bulb. I prefer to connect two self opening switches in arallel into the circuit to the upper bulb. ne of these switches will be connected so that it is closed when the control lever is shifted into reverse position so that the upper light will illuminate the roadway as a backing light when the vehicle is run rearwardly. The other switch may be so connected as to be closed whenever either the clutch lever or brake lever is pushed in, as is now the case with most stop lamps. Drivers differ as to which is preferable.
