Application July 7, 1947, Serial No. 759,316
This invention relates to a device for scaring birds, and more particularly to a device for scaring starlings. A primary 4object of the invention is to provide a bird scaring device to be mounted at a suitable Y the above mentioned character which is simple,
extremely durable, and well adapted to modern economical manufacture.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings, forming a part of this application, and in-which like numerals are employed to designate like parts throughout the same,
Figure 1 is a central vertical longitudinal section through the device, and looking toward the rear of the same,
Figure 2 is a front elevation of the device drawn on a reduced scale, and illustrative of its general appearance,
Figure 3 is a horizontal section taken on line 3-3 of Figure 1, and
Figure 4 is a horizontal section taken on line 4 4 of Figure 1.
In the drawings, where for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 6 designates a horizontal rectangular base, provided with a central upstanding projection or plug I integral therewith, and having corner `openings 8 to receive mounting bolts, or the like. The plug 'I is received by a depending tubular socket 9 formed integral with a generally vertical bracket or stand I0. This stand I comprises opposed upstanding arms II, joined at their lower ends by a horizontal web I2, and an upper horizontal annular flange I3 including an inner annular portion I4. The stand I0 and base 6 are detachably connected by means of a pin l5, or the like.
Rigidly detachably mounted upon the stand I6 is a vertical cylindrical tubular housing I6, hav- 2 claims.. (c1. 46a-124) opening I8. The housing I6 is open at its bottom, and has an vexternal horizontal annular flange I9 integral therewith, which registers with the flange I3. The housing I6 has a large forward vertical opening I9', giving ready access to the interior of the housing, and the opening I9 extends from near the top I'I to near the flange I9. The housing I6 is further provided with a pair of oppositely arranged horizontal arcuate slots 20 in the side wall of the housing, and these slots extend from the transverse center -of the housing to points near the rear of the same, see Figures 1 .and 3. The slots 20 are spaced downwardly from the top I1. The housing I6 serves as the body portion of the owl. A depending tail portion v2| is provided, and this tail portion is integral with the housing and joined to the same at the rear side of the flange I3, Figures 1 and 3. The tail 2I may incline rearwardly toward its lower end. An inspection door 22 is provided to cover the forward opening I9', and this door is offset forwardly and curved providing a forward portion 23 to simulate the breast portion of an owl. The door 22 is attached to the housing I6 by one or more hinges 24, and the door swings horizontally. A pivoted latch 25 is provided and y mounted upon the housing I6 adjacent to the edge of ,thetdoon and serves as a closure member for the door. A depending downwardly tapered extremity 26 is formed integral with the forward side of the flange I9. This extremity 26 is adjacent to the lower edge of the door 22, and with the forward portion 23 thereof simulates the front or breast portion of an owl.
Mounted upon the tubular housing I 5, by means of vertical hinges 21 and adapted to swing horzontally are wings 28. These wings are curved as shown in Figures 3 and 4 and surround the sides of the housing I6 when in the closed position. The wings are adapted to swing open topositions at or near those shown by broken lines in Figure 3. The lower tips of the wings preferably terminate near the web I2, and the tops of the wings are adjacent to the top I'I. The wings 28 together with the housing I6 and door 22 formthe likeness of an owls body. Formed upon the inner curved surfaces of the wings 28, 4adjacent to the slots 20, are split knuckles 29 carrying vertical hinge pins 30.
Disposed vertically within the lower part of the housing I6, and projecting downwardly between the arms II for a short distance is an electric motor 3 I, having a wire 32 which leads to a source of electric current. The motor casing is provided ing av horizontal 'top I'Iprovided with a central with mounting flanges 33 which engage upon the 3 inner annular ange I4. The motor is rigidly mounted upon the flange I4 by means. of screws 34. The annular clearance between the motor and the inner ange I4 is small, and the motor substantially closes the opening at the bottom of the housing l5 and aids in keeping foreign matter from the interior of the housing. The armature shaft 375 of the motor projects upwardly for a' short distance and is providedatitsierd with a sm'all'drive' gear"36 rigidlym'ointed thereon. Rigidly mounted upon the anges 33, and secured in place by the screws 34 is an inverted U-shaped bracket 37, having a hprzontaletop provided with a central clearanceopening 38 for the armature shaft 35. Rotatablxrmountedfupon the top of the bracket 31 is an idler gear39whi5h meshes with the drive gear 3E. ''lhisillerger 39 carries a small gear 49, disposed beneathgit and preferably formed integral therewith.
