3 Claims. (on. lit-s29) This patent matures from .the refiled application on the invention subject matter disclosed in an application 591,247, filed February 5, 1932, which has been abandoned.

The object of the invention is to provide a ment; and generally to provide a direction signal which is of simple form, susceptible of cheap manufacture and of a character to reduce to a minimum the liability to disarrangement of its parts.

With this object in view, the invention consists in a construction and combination of parts, of which'a preferred embodiment is illustrated inthe accompanying drawings, in which:

Figure 1 is aperspective view of the invention.

5 Figure 2 is a sectional view on the plane indicated by the line 2-2 of Figure 1.

Figures 3 and 4 are sectional views on the planes indicated by the lines 3-3 and l-t respectivelyof Figure 2. v

Figure 5 is a perspectiveyiew of the combined compartmental and reflector units.

' Figure 6 is a perspective view of the cover unit.

The improved signal or indicator comprises a housing I generally of diamond shape in elevation and drawn from sheet metal so that the top, bottom, and walls and back blend into each other. The open face of the casing is closed by a cover unit 2 which is formed by the marginal flange 3 telescoping over .the inset or rabbeted marginal portions of the walls of the casing l. The cover unit is punched to provide an opening 5, which defines the arrow head 6 at one side and a similar arrow head 1 at the other, the two being connected by a stem portion 85A transparency, preferably glass, is carried against the inner face of the cover unit within the flange 3 thereof, this transparency being extended to cover the openings II and I2 which are formed in the cover member in the areas between the arrow heads 6 and l and above and below the stem portion 8 respectively.

' The several light units are mounted in the casing respectively behind the arrow heads 6 and 1 and the openings ll and. i2, and to this end there is provided a plate l3 formed with upwardly and downwardly extending arms as well as laterally extending arms. The upwardly and downwardly extending arms I5 and "5 respectively carry the sockets I! and I8 designed for the reception of the bases of the lamps l9 and 20,which are retained in the sockets by the conventional pin and bayonet slot connections 2i.

' The plate i3 is centrally depressed and in this depressed portion is secured to the back wall of the housing I as indicated at l3a. A block of insulation 23 is seated in the depressed portion of the plate, and to it are secured by means of the fasteners 22a and 2222 the contacts 22, which are in the form of spring strips whose extremities bear on the center contacts of the lamps.

ter are engaged with the extremities of the spring contacts 3! and 32 which are mounted on the block 23 by means of screws 3| a and 3H) and 32a and 32?) respectively. This arrangement provides a ground connection for all of theseveral sockets, so that a common return to the sources of current is provided. That the lamps may be selectively lighted, each of the spring contacts is connected with a suitable lead, and several leads or conductors 34 being brought into the casing through an opening 35 in the rear ..wall thereof, which opening is continued through the

insulating block

2,3.

The division of the casing into compartments is accomplished by the use of combined reflector and partition member 31, which is in one piece, being punched from sheet-metal and thereafter drawn into the conformation shown so that a reflecting surface 413 is provided of parabolic curvature adjacent the axis of the reflector which is coincident with the center of the open ing M, which is a clearance opening for its attendant lamp. The combined reflector and partition member 31 is'provided with lateral portions 42 and t3-contacting at the edge M, the space above the extensions defining the compartment back of the opening II in the cover unit and the space below defining the compartment behind the opening l2 of the cover unit. The remote ends 45 of the unit 3! follow the contour of the remote ends of the cover unit and casing. The member 3'! is directly secured to the cover unit 2 by means of fasteners 41 which pass through openings in the cover member through similar openings in the ears 46 on said units, engaging nuts 48 behind said ears.

Screws 49 inserted through the flange 3 of the cover unit at its remote ends are threadingly engaged with the Wall of the casing in the rabbeted portion.

When the cover member or unit is removed, the

compartmental member 31 is removed with it, so.

that in replacing or adjusting the lamps, free access is had to all parts of the casing. When the cover member is replaced, the lamps Z8 and 29 pass through the openings 4| and the member 31 thus provides one compartment for each lamp, while the lateral extensions 43 and 42, besides dividing the casing generally horizontally, extend the compartments of the

lamps

28 and 29 into the connecting shank portion of -the arrow heads. Thus, as the lamps are selectively lighted, either ar ow head and its adjacent stem portion is 11:- luminated or those areas of the transparency behind the openings H and I2,

The invention having been described, what is claimed as new and useful is:

l. A reflecting unit for direction signal's provided with a plurality of parabolic reflecting compartments, said unitand the reflecting compartments being in a unitary structure, and

stamped and drawn from, sheet metal, whose wall has a definite configuration simulating a pair of direction arrows with one end of each of the arrow stems adjacent the other.

2. In a direction signal, a casing having a closed rear wall and an open front, a removable cover for the open front provided with an opening defining a pair of arrows with one end of each of the arrow stems adjacent the other, a partition unit in said casing and having reflecting parabolic compartments, said unit being in a unitary structure stamped and drawn from sheet metal and whose wall has a definite configuration simulating a pair of direction arrows with one end of each of the arrow stems adjacent the other and conforming to the pair of arrows defined by the opening in the cover, said compartments having clearance openings for lamps.

3. In a direction signal, a casing having a closed rear wall and an open front, a removable cover for the open front provided with an opening defining a pair of arrows with one end of each of the arrow stems adjacent the other, a partition unit in said casing and having reflecting parabolic compartments, said unit being in a unitary structure stamped and drawn from sheet metal and whose wall has a definite configuration simulating a pair of direction arrows with one end of each of the arrow stems adjacent the other and conforming to the pair of arrows defined by the opening in the cover, said compartments having clearance openings for lamps, and. means adjacent each other near the center of the length of the unit and being integral parts of the wall of the unit and carrying devices to secure the unit to the cover.
