DOORSTOP Filed Sept. l2, 1934 Inventor Attorney Patented Nov. 5, 1935 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to improvements in door stops and has for its particular object to provide a device of this character which is simple in construction, easy to manipulate, positive in its action, and inexpensive.

A further object is to provide a compact device which may be folded and lies close to the door. These and other objects hereinafter set forth are obtained by the means illustrated in the accompanying drawing, in which:

Figure 1 is a fragmental perspective showing an open door of a garage or the like and showing the door` in connection with the supporting frame of the usual type and also illustrating the improved door stop in use and holding the door open.

Figure 2 is a perspective view of the base plate.

Figure 3 is a perspective view of the cover plate for holding the door stop in its proper position on a door.

Figure 4 is a perspective view of the prop-rod or brace member constituting the principal feature of my invention.

Figure 5 is a perspective View of a clip for holding the rod in out-of-use position.

Figure 6 is a side view cfa portion of the door stop showing the manner of assembly and support for the rod; and Figure 7 is a view similar to Figure 6 showing a slight variation in the construction of the base plate.

In doors of the garage type, or barn doors, or doors for many types of buildings that are swung on hinges, it is frequently necessary to secure the doors in an open position to permit ingress or exit of vehicles of various kinds. It is also essential to so support these doors that they will not bang or move when in open position and in the means provided it is essential that the door be properly supported in its open position against heavy winds or other factors that would cause them to close at some inopportune time or bang in such a manner that the hinges and door would be affected or broken.

With this in mind, I have devised a simple structure having a minimum of parts, yet a positive and simple action that may be evident to anyone having occasion to prop a door in an open position.

My device, therefore, consists of a supporting prop or brace member which is secured to a door, near the bottom thereof, by suitable supporting plates which also form a part of my invention and which provide freedom of action of the prop member for either a holding position or a nonuse position.

The prop-rod consists of a rod or shank I0 of suitable length having a T or cross head1 I formed at one end and a spade-shaped ground contact end I2 having a fairly sharp edge I3 and prefer-- ably a notch I4 for engagement either with the 5 ground or a concrete driveway or oor, as the case may be.

As a means for securing the prop-rod in a pivotal manner to a door, through the use ofv a T- head II, a pair of plates illustrated in Figures 2 l0 and 3 are utilized, the plate I6 constituting a base plate secured adjacent to the wood frame of the door and a cover plate II superimposed on the plate I6. The plate I6 is provided with screw or bolt holes I8, while the plate I'I has correspond- 15 ing and registering holes I9. The plate I6 also is formed with a central, horizontal ridge or bead 20 for contact with the T-head II and the cover plate is also rigid, but to a greater extent as 2I and also carries a slot 22 formed vertically into 20 the plate II through which the shank Il) may be free for pivotal movement in the several positions that will be assumed by the said prop-rod when in use or out of use.

In forming the slot 22, a portion of the metal 25 is removed and a portion of the metal, as 23, is left and bent outward as best indicated in Figures 3 and 6 to form a positive stop for the proprod I0 to insure that the rod at all times will remain at a position angular to the vertical or the 30 door structure.

In some instances it is desired, also, to form the member 23 of greater length and bending the ure 7, so that a slight spring action is provided 35 y to insure resiliency and a slight movement of the prop-rod IIJ with respect to its set position when wind or other force strikes the door and causes a, slight movement thereof. This insures that the prop-rod in its engagement with the 40 ground or a driveway will be more positive in its holding action and through repeated movements of the door will not be liable to permit the door to close.

In assembling the structure that I have thus 45 described, a good illustration of such an assembly is shown in Figures 6 and '7.

The T-head of the prop-rod I0 is inserted through the slot 22 of the cover plate I1. The cover plate is then engaged with the backing and support plate I 6 and the structure as thus assembled is then screwed to the door at a suitable place near the bottom thereof. The spade-end I2 of the prop-rod is slightly bent downward and inward so that a fairly sharp edge is presented for contact with the ground or with the driveway. When it is desired to hold a door open the rod is positioned in the manner shown in Figure 1, whereby the terminal end I2 will contact with the ground or drive, at Whichtime the door will be supported against any closing movement. It may be pushed open as far as desired and thereafter will be supported by the prop member.

When the door stop is not desired for use a suitable clip formed after the manner of Figure 5 may be used and placed above the door stop fastening plates, as shown in Figure 1 and this acts as a keeper for the prop as indicated in the dotted lines of that figure.

Having thus fully described my invention, what I claim as newand desire to secure by Letters Patent is:

In a door stop, the combination of a prop-arm pivotally supported on a door, said pivot support comprising a ribbed base plate and a ribbed and slotted covering plate superimposed on the face plate and supporting a T-head on the prop-arm, and said slot permitting a vertical pivotal movement of the prop-arm.
