SECURITY POOR HOLDER Filed Aug. 17, 1945 2 Sheets-Sheet? IN VEN TOR.

Patented Feb. 1o, 1948 UNITED STATES PATENT GFFICE 2,435,861 SECURITY noon HOLDER Wylie S. Wlkison, Bayard, N. Mex. Application August 17, 1945, Serial No. 610,912 7 Claims. (Cl. 292-341) This invention relates to a door holder and it is one object of the invention to provide a door holder adapted to be applied to a door and a door frame and by means of which a door may be held open various degrees and prevented from being blown shut r open out'of the desired position.

Another object of the invention is to provide a door holder so formed that it may be actuated with one hand and readily moved to secure or release the door.

Another object of the invention is to provide a door holder which, when applied to a door and a door frame for use, will not detract from the appearance of the door.

Another object of the invention is to provide a door holder which consists of a small number of parts and is quite simple in construction and may be manufactured at small cost.

The invention is illustrated in the accompanying drawings wherein:

Figure 1 is a view in elevation showing the improved door holder applied to a door and a door frame in position for use.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a view taken along line 3-3 of Figure 1.

Figure 4 is a fragmentary sectional View taken along line 4-4 of Figure 1. y

Figure 5 is a fragmentary top plan view of the door holder, an opened position of the door being indicated by dotted lines.

Figure 6 is a View in elevation of Figure 5.

Figure 7 is a fragmentary sectional View taken along the line I-'I of Figure 6.

This improved door holder is applied to a door I and the upper portion of a door frame 2 and when so applied constitutes means for holding the door opened as far as desired and preventing the door from blowing shut.

A bearing bracket 3 is attached to the upper portion of the door frame S and has an ear 4 to which an arm or bar 5 is connected by a bolt B. The arm or bar 5 projects from the door frame and through its outer end passes a bolt I 'carrying a circular block 8 having teeth about its peripheral edge face. The bolt I not only connects the block with the arm but also prevents the block from turning relative to the arm. The lower portion of the bolt projects downwardly from the block and passes through a slot 9 formed in a bar I0 longitudinally thereof. The bar I Il may therefore have sliding movement radially of the block and also pivotal movement about the bolt.

The bar I0 is shifted longitudinally in order to move the tooth II of a latch I2 into and out of engagement with the toothed block or disc 8. This is accomplished by door-carried mechanism including rods. I3 and I4. The shaft or rod I3 extends across the upper end of the door and slidably mounted through a bracket I5 carried by the door, the front end of rod I3 being pivoted to an arm I 6 projecting outwardly from the upper end of shaft I4. The shaft or rod I4 extends vertically adjacent the free side edge of the door and has its lower portion rotatably mounted through a bracket I'I and terminating in a crank handle I8 by means of which it may be rotated and impart swinging movement to arm I6 for shifting the rod I3 longitudinally. A curved plate or strip I9 is secured to the door and extends transversely of rod I4 between the rod and the door and serves as a wear plate for the rod and also as a brake for preventing too free turning of the rod. The inner end of rod I3 is pivoted to the inner end of a link or lever 20 pivotally mounted between ears 2l of a bracket 22 by a pin 23, and this lever 20 carries an upstanding block or post 24 carrying an arm 25 at its upper end. The arm 25 projects outwardly from the block 24 and its outer end is pivotally connected with the inner or rear end of rod I3 by a pin 26. Shifting of the rod I3 longitudinally In one direction will cause the bar I0 l-o be shifted longitudinally in a direction to move the latch I2 away from the disc 8 and permit free opening or closing movement of the door. After the door has been moved to the desired position. the rod I4 will be turned by its handle I8 to shift the rod I3 longitudinally in the opposite direction and the latch will be moved into engagement with the toothed disc or keeper and the door will be securely held against movement out of the desired position of adjustment. Since the rods I3 and I4 extend parallel to and close to the marginal edges of the door, the device may be applied to doors having glass panels, and this arrangement of rods also disposes the rods and mechanism controlled thereby in such position that they will be inconspicuous and not detract from the appearance of the door.
