United States Patent 2,938,243 BIRDPROOFING DEVICE I Julius Stanley Peles, 523 W. 184th St., New York, NY.

Filed Nov. 13, 1953, Ser. No. 391,895

1 Claim. (Cl. 20-1) The present invention relates to birdproofing and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided a device which may be quickly and easily attached to a ledge or window sill of a building to be protected from starlings, sparrows,

- pigeons and the like and which is designed to prevent such birds, regardless of size, from alighting in the places protected by the devices of the present invention. In one form of the invention there is provided a novel base strip which is adapted to be horizontally attached to the building and which is provided with means for mounting thereon a plurality of vertically extending fingers. In the first embodiment of the invention, such means comprises a plurality of upwardly struck longitudinally spaced loops formed in the base plate and a horizontally extending foot receivable in such loop which foot is formed integrally with the lower end of its finger. The fingers are arranged upon the base plate in a novel manner whereby to prevent birds of different sizes from alighting thereon. In another form of the invention, the means for mounting the fingers upon the base plate consists of the provision of a horizontally extending foot integrally formed with each of the fingers and which foot is attached by a rivet in each case to the base plate.

It is accordingly an object of the invention to provide devices of the character set forth which are simple in construction, inexpensive to manufacture and yet effective and eflicient in use.

Another object of the invention is to provide, in a device of the character set forth, novel means for mounting upon a base plate forming a part of the invention a plurality of novel vertically extending fingers likewise forming parts of the invention.

A further object of the invention is to provide, in a device of the character set forth, a novel finger having means incorporated therein for the prevention of the secure grasping thereof by the claws of birds.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

Figure 1 is a perspective view of an embodiment of the invention,

Figure 2 is an enlarged fragmentary longitudinal sectional view of a base plate illustrated in Figure 1,

Figure 3 is an enlarged transverse vertical sectional view of the device illustrated in Figure 1,

Figure 4 is a sectional view taken along line 4-4 of Figure 3,

Figure 5 is a fragmentary side elevational view, partly broken away, of a modified form the invention may assume, and

Figure 6 is an enlarged fragmentary plan view of the device illustrated in Figure 5.

Referring more particularly to the drawing, there is shown therein an elongated horizontally extending base plate generally indicated at 10 preferably formed of flat metal and provided adjacent one of its longitudinal 2,938,243 Patented May 31, 1960 edges with a raised portion 11. In theraised portion 11 there is provided a series of longitudinally spaced longitudinally extending slots 12. The plate is likewise provided with a series of longitudinally spaced upwardly and transversely extending loops 13 which are preferably and as shown formed integrally with the plate 10 by striking the same therefrom.

There is also provided a series of relatively long vertically extending fingers 14, a series of like medium-sized fingers 15 and a series of relatively short fingers 16. Each of the fingers 14, 15 and16 is provided at its lower end with an integrally formed horizontally extending foot portion 17, the feet 17 each being receivable in one of the loops 13.

Particular reference to Figure 3 of the drawing will show that each of the fingers 14, 15 and 16 is provided with a main body portion 18 having parallel sides and an upper body portion 19 having upwardly and inwardly converging sides which terminate in a rounded upper end 20. To provide rigidity to the fingers, each is pro vided with a centrally disposed longitudinally extending corrugation or ridge 21 which extends from point adjacent the bottom thereof to a point adjacent the upper rounded end 20. Each of the fingers is formed of a fiat piece of metal having sharp or very narrow edges.

In order to assemble the device as is illustrated in Figures 1 to 4, inclusive, it is only necessary to afiix the plate 10 in a position to be protected as, for example, a ledge 22. This is accomplished by nailing the same to the ledge 22 by nails 23 which extend through some or all of the slots 12. Thereafter the fingers 14, 1S and 16 may be mounted upon the plate by inserting the feet 17 thereof into successive loops 13. In the preferred embodiment of the invention, each finger 14 is followed by a medium-sized finger 15 which is, in turn, followed by a relatively smaller finger 16 after which such series is repeated as many times as possible with the plate 10. Raised projections 17 on the feet will hold the fingers against outward displacement from the loops. Insertion past the loop as to projection 17 is possible due to the resilience of the metal foot 17, Fig. 3.

It will be seen that with such arrangement birds having long legs will be prevented from resting upon the ledge 22 by means of the relatively longer fingers 14 while medium-sized birds will likewise be prevented from resting by means of the fingers 15 and that smaller birds, such as sparrows or the like, will be prevented from resting by means of the relatively short fingers 16. Birds of all sizes will be prevented from grasping any of the fingers 14, 15 or 16 due to the fact that the portion 19 is provided with sides which slope downwardly and outwardly and would hence cause the claws of the bird to slip in a downward direction whereupon the bird would be forced to come into contact with the rounded point 20. Birds are also prevented or discouraged from grasping the various fingers 14 to 16, due to the fact that the edges of such fingers are sharp or relatively thin and would hence be uncomfortable to the claws of such birds.

In the form of the invention illustrated in Figures 5 and 6, the feet 17 of the fingers 14, 15 and 16 are each apertured for the reception therethrough of a rivet 24 whereby the same may be affixed centrally upon the plate 10, the latter being provided with suitable openings for the reception of the rivets 24.

In the last-mentioned form of the invention, it will be apparent that the birdproofing devices may be preassembled at a factory prior to shipping the same to the user whereas in the form of the invention shown in Figures 1 to 4, inclusive, the device may be assembled at the point of use. It will also be apparent that the arrangement of a plurality of series of short, medium and long fingers may be provided in the form of the invention shown in Figures 5 and 6. The device can be made of all types of metal, either corrosive or noncorrosive, and all types of wire, wood or plastic.

While but two forms of the invention have been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

A birdproofing device comprising ari elo'iigated, horiiontally-extending', substantially fiat, resilient base strip adapted to flatwise overlie the surface of a ledge, said base strip having a raised portion to afford resiliency to portions thereof, a series ,of longitudinally-spaced openings running along the raised portion thro'ugh which attaching nails are extended to secure the base strip to the ledge, a series of longitudinally-spaced, upwardlyextending, transverse loops running with the openings along the strip, and a plurality of relatively long, medium, and short vertically-extending fingers detachably secured under said loops, each of said fingers having a lower horizontally extending foot portion. with a raised projection thereon engageable with a side edge of the loop to normally retain the finger against lateral removal from the loop when in place thereunder, the resiliency of the raised portion of the base strip facilitating the insertion and removal of said foot portion under and from the loop to free the raised projection therefrom and an upper portion extending vertically and having a longitudinally-extending corrugation therein to stiifen the same, said upper portion having upwardly converging sharp side edges.
