s Claims. (Cl. 232==35 Tli'epresent invention rlate'sto an automatic mailbox signal and more particularly to a rural mailbox signal which may be mounted on any conventional mailbox and which moves aut'omatically'to signalling position in response to actuation or the door of the rural mailbox.
'Itis well-recogni'z'ed'thatthe owner of a rural mailbox has no knowledge of when mail or other matter has been deposited inhism'ailbox by the mail carrier. In anticipation of "the mail delivery, the owner usually "makes repeated trips to the mailbox to'ascertain whether "or not mail has "been deposited. 'He can many times seethebox 'fromwithin liis home, but unless he-actually 's'ees'the'mailrnan depositthe mail he remains in ignoactuated to signalling position without any extra effort on'the part ofthe mailman. Additionally, such a signal should be capable of being associated withany conventional mailbox in a simple manner preferably without the requirementof any tools or -the alternation of the mailbox in any manner.
Accordingly, it is an object of the present invention to provide an improved mailbox signal whichmay readily be associated with the mailbox, without the necessity of altering any .part of a-conventional=mral mailboxand preferably without the requirement of any toolswhatever.
It is another object of thepresehtinvention toprovide a-simple folded signalling devicefor a mailbox which will be actuatedto a signalling .position by an exceptionally simple mode of operation, as relative movement occurs between two parts of a mailbox.
It is a further object of the present invention to provide an improved signal for a mailbox-which'will operate automatically when the mail carrier performs the single necessary op eration of actuating the cover of the mailbox While depositing mail therein. I
Still another'object of the presentinvention is to provide an improved mailbox signal which is clearly visible 'at a substantial distance from the mailbox when in the signalling'position and yet which is completely hidden and fairly well protected from the elementsof nature when in the non-signalling position.
Another object of thepresent invention resides in the provision of improved operational parts for a mailbox signal so as to increase its operational reliability and secure successfulperformance under any weather conditions and at the same time to simplify the manufacturing and assembling procedures.
It is another object of the present invention to provide an improved gravity actuated mailbox signal which can readily be attached to any existing mailbox.
Further objects and advantages of the present invention will become apparent as thefollowingdescription 2,808,982 Patented Oct. 8, 1957 proceeds and the features of novelty which characterize the invention will be pointed out with particularity in the c'laims'annnexed to and-forming apart of the specification.

Referring now tothedrawings, thereis generally 1 illustrated a'folded signal securedto amovabl'c portion of the'mailbox, which signal is automatically actuated to itssignallingposition by the-action'of :gravity'when the-mailbox cover is opened. The signalm'ay be secured to the mailbox in different ways-'asdescribed'in Idetai-l hereinafter. The :folded signal includes a signalling element which is pivotally connected at its'lower endwhen in the non-signalling position to the rest of the signal so that under the force of gravity it will automatically pivot about its lower end and depend downwardly to a signalling position.
Referring specifically now to the drawings, there is illustrated in Figs. 1 through 5, inclusive, a first embodiment of the automatic mailbox signal of the present invention. This signal generally indicated at 10 is associated with the cover 11 of a conventional mailbox 12. As will be understood, the rural mailbox 12 of the conventional type consists of an elongated closed receptacle for the storage of mail and other matter whose parallel, rectangular longitudinal sides extend upward to form a half cylindrical top. The back end of the receptacle is closed by an end wall (not shown) while the bottom is closed by a wall 13. The front open end is closed by the cover 11 which is adapted to be pivoted at its lower end about a hinged pivot pin 11a between a closed, substantially-vertical position as shown in Figs. 1 and 3 of the drawings to an open, substantially-horizontal position as shown in Fig. 2. Preferably the mailbox 12 is provided with suitable latching means for maintaining the cover 11 in the closed position. Such latching means preferably comprises cooperating spring clips 14 and 15, secured to the cover 11 and box 12, respectively, which are readily releasable means conventionally employed with such mailboxes.
The rural mailbox automatic signal 10 of the present invention illustrated as associated with the mailbox 12 includes a signalling element 16 pivotally mounted by hinge means 17 to an intermediate support element 18, hereinafter referred to as intermediate element 18, which, in turn, is pivotally connected to a signal mounting element 19, hereinafter referred to as mounting element 19, suitably secured to the mailbox 12.
In order to afiix the mailbox signal 10 to the cover 11 of said mailbox 12, without the use of any tools and without altering the mailbox in any way, the mounting element 19 is illustrated as a U-shaped wire element having the ends of each arm of the U formed into a closed loop 19a. These closed loops 19a provide pivotal connections with the intermediate element 18 which is provided with cooperating openings 18a to receive the loops 19a. The arms of the U-shaped support adjacent the bight portion are folded back to form a pocket 20 best shown in Fig. 5 of the drawings clampingly to receive therein the lower edge of the cover 11 of mailbox 12. Preferably, the mounting element 19 is formed of somewhat resilient or spring wire to insure good clamping action with the cover 11. It will be apparent that the mounting element 19 can be secured to this cover 11 merely by forcing the lower edge of the cover into the pocket 20 which comprises an upward movement of the mounting element 19 as viewed in Fig. 1 of the drawings. The resilient nature of the mounting element 19 will cause it firmly to grip the cover 11 as if it were integrally united therewith.
To provide a folded signal the intermediate element 18 is pivoted at its upper edge to the mounting element 19. When the cover 11 is closed as shown in Fig. l the intermediate element 18 hangs vertically parallel to the cover 11. When, however, the cover 11 is open as shown in Fig. 2 the intermediate element 18 again hangs vertically but now it is substantially perpendicular with the cover 11. In other words, the intermediate element 18 hangs freely and remains in a consistently, substantially-vertical position during the pivotal rotation of both the mailbox cover 11 and the attached mounting element 19. In short, the angle of incidence between the intermediate element 18 and the cover 11 will range from to 90 as the mailbox cover 11 is pivotally rotated from its closed, substantially-vertical position to its open, substantially-horizontal position.
To pivotally connect the lower edge of the signalling element 16 as viewed in Figs. 1 and of the drawings,
which is illustrated as a generally rectangular member, but which might have any other shape, to the intermediate element 18 the hinge means 17 are provided which merely may be wire loops extending through cooperating openings 16a and 18b in the elements 16 and 18, respectively, at the adjacent edges thereof. The hinged relationship of the elements 16 and 18 provides the folded signal of the present invention which may assume a folded or overlapping non-signalling position or an unfolded or extended signalling position.
When the mailbox cover 11 is in a closed position and the signal 10 is in the folded non-signalling position, the signalling element 16 is disposed in a substantially vertical plane, between the cover 11 and the intermediate element 18 which intermediate element hides it from view. The force of gravity maintains the element 18 vertical under these conditions and prevents the signalling element 16 from moving out of this non-signalling position. When, however, the cover 11 is moved to the open position, the intermediate element 18 tends to stay vertical with the result that it swings away relative to the cover 11 and no longer restrains the signalling element 16 between it and the cover 11, whereupon the signalling element 16 pivots about pivot means 17 to the extended or unfolded position shown in Fig. 2 of the drawings. Even after the cover 11 has been moved to the closed position as shown in Fig. 3, the signalling element 16 in its unfolded signalling position extends below the bottom of the mailbox 12 and provides notice to all that a mail delivery has been made or at least that the cover 11 has been actuated.
Preferably the signalling element 16, at least on the surface exposed when in its signalling position, but usually on both surfaces, is provided with a readily visible surface. These surfaces might be colored a bright, readily visible color or preferably there might be applied thereto some paint or fabric which can be seen for substantial distances. Such material is indicated in somewhat of an X pattern and designated at 22 in the drawings.
The mailbox signal 10 may be easily reset to the nonsignalling position of Fig. l by a simple manual operation. When the mailbox cover 11 is in the closed position one can merely pivot the signalling element 16 about hinge means 17 behind the element 18. When the mailbox cover 11 is in the open position one can similarly pivot the signalling element 16 behind the intermediate element 18 and then hold these elements in this position while moving the mailbox cover 11 from its open position to its closed position.
In view of the detailed description included above the operation of the folded signal means 10 will readily be understood and hence no further discussion will be included herewith. It will be appreciated, however, that a very simple signal means is provided which can be attached to a mailbox in a simple manner without the requirement of any tool. The operation of the signal is positive and resetting is very simple. It can readily be applied to any new or old mailbox.
It will be understood that the intermediate element 18 of Figs. 1 to 5 is merely a support for the signalling element 16 and it need not take the rectangular form illustrated. Thus, in Figs. 6 to 9, of the drawings there is illustrated a modification of the mailbox signal 10 generally designated as 10 in which every element with the exception of the intermediate element 18 is the same as in the preceding embodiment. The corresponding parts of Figs. 6 to 9 are designated by the same reference numerals as in the preceding figures. Instead of the intermediate element 18 which merely acts as a support for the signalling element 16 there is provided another intermediate element in the form of a pair of parallel wire-like elements 23 and 24 provided with loops 23a and 2441, respectively, at the upper ends and loops 23b and 241'; at the lower ends, respectively, thereof.
mounting element 19 by engagement with the loops 19a of mounting element 19 as clearly shown in Figs. 6, 7 and 9 of the drawings. The loops 23b and 24b similarly make hinging connection with the lower edge as viewed in Figs. 6 and 9 of the signalling element 16 by engaging the openings 16a therein. The functional operation of the parallel members 23 and 24 is identical to the functional operation of intermediate element 18 described heretofore.
In the arrangements described thus far the mailbox signals 1t) and are designed for frictional attachment to any conventional rural mailbox which can be accomplished without the use of tools and without altering the mailbox in any way. For factory installation of the foldable signal of the present invention the mounting element 19 could have many forms, one of which is shown in Figs. 10 to 13 of the drawings. This signal generally indicated by the reference numeral 25, is identical with the signal 10 just described except that instead of the mounting element 19 a mounting element 27 is provided. The corresponding parts of Figs. 10 to 13 are designated by the same reference numerals as in Figs. 6 to 9 of the drawings.
As illustrated, the mounting element 27 is of somewhat V-shape with the apex of the V formed into a loop 27a and the ends of the arms of the V each provided with a loop 27b. The loop 27a may be secured to the cover 11 of the mailbox by a rivet screw or other fastening means specifically indicated as a bolt 29. The loops 27b are hingedly related to the parallel supports 23 and 24 just as these supports were hinged to the mounting element 19 in the preceding embodiment. It will be understood that the mounting element 27 might be dispensed with and instead loops from the cover 11 could be punched out to hinge with the intermediate element which intermediate element could be the members 23 and 24 of the intermediate element 18. Moreover, the mailbox signal 25 can be attached by the mailbox owner to an existing box merely by drilling a small hole in the cover 11 and attaching the signal with the bolt 29. The functional operation of the mailbox signal 25 is identical with that described for the signals 10 and 10.
In Figs. 14 to 17 of the drawings there is illustrated still another embodiment of the present invention employing a foldable signalling element with modified means for securing the same to a mailbox. This signal generally designated at 30, comprises the intermediate support element 18 of Fig. 1 hingedly related to the signalling element 16 by the hinge loops 17. Instead of the mounting element 19 an entirely different mounting element 31 is provided comprising a plate 31a and an extension member 31b one end of which is secured to the plate 31a and the other end of which is terminated in a hook 32. This hook 32 is adapted to receive therein the lower edge of the mailbox cover 11. Unlike the mounting element 19 this hook alone will not secure the mounting element 31 to the cover 11. To further secure the mounting element 31 there is provided a tension spring 34 having one end connected to the plate 31a and the other end connected to a hook member 35 which is shaped to readily engage the latch memher or spring clip 14 which is conventionally provided on rural mailboxes. The tension spring therefor maintains the hook 32 in engagement with the lower edge of the mailbox cover 11 thus firmly supporting the mailbox signal 30 in position. Suitable hinge member 36 hingedly relate the intermediate element 18 and the plate 31a. The mailbox signal 36, except for the means of supporting the same from the mailbox, functions in exactly the same way as in the preceding embodiments.
It will be appreciated that the intermediate element 18 which is always visible provides an excellent surface to which the mailbox owners name may be applied. In Figs. 14 and 15 of the drawings there is illustrated the indicia 40 which can be applied directly to the plate or intermediate element 18 or which may be on a separate plate 41 suitably secured to the intermediate element 18.
While there have been illustrated several embodiments of the mailbox signal of the present invention, it will be apparent that numerous changes and modifications thereof will occur to those skilled in the art. It is aimed in the appended claims to cover all those changes and modifications which fall within the true spirit and scope of the present invention.
