UNITED STATES HAROLD S. WILSON, OF IRVINGTON, NEW JERSEY.

DOOR HOLDER.

Application filed November 2, 1923. Serial No. 672,275.

swung open and hold the door open by t'rictional means until the joint of the toggles is broken.

The object of this invention is to provide a few parts but efficient and easy latching and also an easy intentional releasing of the stop by an upsetting oi the alignment of the tog gles.

My invention is illustrated in the accompanying drawings in which Figure 1 is a perspective view of the holder holding a door open. Figure 2 is a section showing the holder on a door in open and in closed position. Figure 3 is a perspective view or part of one of the toggles and Figure 4 is a crosssection taken on line 4- l in Figure 2.

In the drawing, 10 indicates the door frame and 11 indicates the door which are equipped with a door holder comprising a toggle 12 and a toggle 13 which are hinged together as at 1 1-, this hinge being short of one end of the toggles so that one toggle has a projecting end 15. The toggle 12 is fastened to the door Frame so that it can swing. In the drawing, this fastening consists of a pivot 16 which secures the toggle 12 to a plate 17 fastened by screws 18 or other means, to the upper part of the door frame.

The toggle 13 is pivoted to the door as by means 01"? the bracket 19 to which it is secured by a pivot 20. The projecting end oi: the toggle 12 has a stud'21 which preferably has a roiznded bottom surface, its projecting part being toward the toggle 13. The toggle 13 has a hole or other form of recess 22 which is placed so that it receives the stud 21 when the r": are aligned. On the toggle 13 adja centto the hole 22, and in the path oi the stud when it is swung over the toggle 13, is a groove 23. This groove is shalloweron the end adjacent to the hole 22 and deeper at its outer end 24 so that, as will be evident trom Figure 4, when the toggles are being swung together and the stud 21 engages the groove 23, the groove exerts a cam action and the necessary distortion of the toggles 1s easlly accomplished to the point where the stud 21 snaps into the hole 22. A stop 25 usually formed integral with the toggle 13, prevents any excessive swinging oi the door forcing the toggles beyond'their aligned position.

To provide for a ready closing of the door by breaking the joint of the toggles, I fasten the chain 26 to the shorter toggle 13 on the side opposite that on which the stop 25 is located and run this chain through an eyelet 27 on the door which is on the same side of the toggle '13 as the fastening 28 of the chain so that when the handle 29 is pulled, the toggle 13 is not only pulled toward the door and the door toward the toggle, but the toggle is pulled downward enough to distort it slightly to enable the rounded face of the stud 21 to ride easily into the groove 23 and then once the alignment of the toggles has been brokenythe door can be easily swung to closed position in which the toggles assume the position shown in full lines in Figure 2.

It will be evident that minor changes such as a pulley in place of the eyelet 27 and other slight imodifications, can be introduced without departing from the scope of the invention;

I claim:

The combination of a door casing and a door, with an arm pivotally secured at one end to the door, and a second arm pivotally secured at one end to the casing, the arms being horizontally disposed the arn'is being pivoted together so that onehas a short proj ecting end, a stud in said end, the other arm having a hole to receive the stud and having a groove leading to the hole, said groove being deepest at its outer end and shallowest at the hole to cause a cam actionto cause a slight distortion of the arms when the stud passes through the groove to the hole, and a chain secured to the arm having the groove and near said groove and is slidably secured to the door so that when the chain is pulled the arms are slightly distorted and their align ment broken and the closing of the door thereby initiated.

In testimony that I claim the foregoing, I have hereto set my hand, this 12th day or October, 1923.
