AUTOMATIC CATCH FOR GARAGE DOORS.

Application filed July 2,

This invention relates to door catches, and has for one of its objects the provision of a novel, simple and inexpensive device of this character especially adapted for use in connection with a garage door and adapted to automatically engage the door when it reaches its fully opened posit-ion for the purpose of holding it in such position.

A further object of the invention is the provision of a door catch of the character stated which may be readily secured in place for use and which shall be capable of withstanding rough usage.

The invention consists of the construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawing, wherein:

Figure 1 is a view in side elevation of a door catch constructed in accordance with my invention, the same being illustrated in the act of holding a garage door in opened position;

Figure 2 is a top plan View of the parts shown in Figure 1, and

Figure 3 is a detail perspective view of the catch.

Corresponding and like parts are referred to in the following description, and designated in the several views of the accompanying drawing, by similar reference characters.

In the drawing 1 designates a garage door and 2 the bottom cleat thereof.

In accordance with my invention a post 3 is driven into the ground adjacent the free edge of the door 1 when the latter is in opened position, and to this post is pivotally secured the catch which is designated in its entirety by the numeral 1. The catch 4 comprises a bolt 5 which is secured by a pivot 6 to one side of the post 3. The bolt 5 projects forwardly beyond the front side of the post 3 and is provided at its forward end with an upwardly extending retaining head 7 having a vertical inner end 8 and a downwardly and forwardly inclined upper side 9. A weight 10 extends upwardly from the inner ent of the bolt 5, and is of substan tially sector formation in contour. The pivot 6 passes through the weight 10, and the latter is provided with an arcuate slot 11 arranged concentrically with relation to the pivot 6. A screw 12 or the equivalent thereof is carried by the post 3 and passes through the slot 11, and is adapted to limit the upward swing of the bolt 5 under the influence 1925. Serial No. 41,164.

of. the weight 10. A screw 13 or the equivalent thereof is carried by the post 3 and passes through the slot 11 and is adapted to limit the downward movement of the bolt 5 when the door 1, during the movement thereof from closed to opened position, con tacts with and rides over the inclined side 9 of the head '7 and when the bolt is depressed to release the door.

The weight 10 normally holds the bolt 5 in a horizontal position, and whenthe bolt is in this position the upper end wall of the slot 11 contacts with the element 12 and the lower end wall of the slot is spaced downwardly from the element 13. It will thus be seen that during the movement of the door 1 into opened position, the bolt 5 is adapted to be depressed to permit the door to pass rearwardly beyond the head 7. lVhen the door reaches this position the weight 10 returns the bolt 5 to and holds it in normal position, with the result that the door is engaged and will be held opened until released. To release the door 1 it is only necessary to depress the bolt 5 far enough to carry the head 7 below the lower edge of the door, and this may be done by placing the foot upon the inclined side 9 of the head 7 and exerting a downward pressure thereon.

In order to insure the prompt return of the bolt 5 to normal position after it has been depressed by the door 1, the weight 10 is provided with an impact end 14 which is formed by cutting away a portion of the front edge of. the weight as indicated at 15. The door 1 contacts with the impact end 14 immediately after passing the head 7 and due thereto an upward swinging movement is imparted to the bolt 5.

From the foregoing description, taken in connection with the accompanying drawing, it should be apparent that the catch is positive and quick of action, that it will automatically engage and retain the door in opened position, and that it may be readily moved into door-releasing position when it is desired to close the door.

While I have described the principle of operation of the invent-ion, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the invention as claimed.

hat is claimed is:

An automatic door catch comprising, in combination with a support, a straight bolt pivoted to the support and provided at its forward end withannipw'ardlyextending retaining head having a downwardly and forwardly inclined upper side, a weight carried by and extending upwardly from the rearward end of the bolt and provided with an arcuate slot concentric to the pivot of the carried 'by'the support and passing through said slot of the weight. 7

In testimony whereof I afi'ix my signature.
