Application filed December To al@ whom t may concern.'

Be it known that I, AUGUST ERNST, acitizen of the United States, residing in the city of St. Louis and State of Missouri, have in-r vented a certain newand useful jDevice'for Holding and Locking Hinged Garagey Doors in Their Open Position, of which the follow-A ing is a specification. 4

My invention relates to a device for holding and locking a hinged garagedoor in itsl open position, and, has for vits object to provide simple A'means lwhiclrwill hold and lockY a hingedy garage door in its fopen position to preve'ntanypossible chance ofthe door being closed by a gust of windyor on its own accord. f i s `A further object of the kinvention is `tov provide a devicewhich will bev simple and inexpensive in constructionowing ,to the fact' that it can be made from pipe and pipe couplings, if desiredand which' will `be strong,`durable, out of the way and in everyl Way PlOve highly eiiicient forthe purpose intended. fw n scribed and finally pointed out `in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification wherein like characters of `reference denotesimilar parts throughout the several views:`

Fig. l, is a top plan view of a pair of hinged garage doors having my `invention applied thereto.

Fig. 2, vis a side elevation `of the device,'

, taken on line 2 2 of Fig. 1.v

, Fig. 3, is a plan view. of the devicejwith portions thereof removed'. '"1

Fig. 4, is a detail of a swivel oint between` the door and the door brace-rod. .y

Referring to the drawings, 1 indicates the side walls of a garage made 'from vsheet metal, or any other suitable material, "and, 2 represents a pair of doors hinged, as at 3. 4 represents the front wall of the garage above the doors 2, while 5 indicates a suitable cross piece, or support connected atopposite ends to the side walls 1 of the garage.

In carrying out the aim of my present invention, I employ a T-coupling 6 which is suspended from the cross-piece 5 by means of the .pipe connection 7 which is provided 1.2, 192:1.`v` serial No. 521,757.' f

yat its upperendv with a Inut 8. -The coupling 6 'is braced from the? front wall 4. by means of a pipe connection having afsuitable foot 10 which is fixed to the wall Las clearly shown-infF ig. K2;V 11 indicates av pipe connectiondepending from the coupling 6. 112 indicates a sleeve coupling which has screw V"threjiadedyconnection, as at'f13,.with the arm 145 ofthe sleeve 125so that itmay turn with relation tothe pipe connection 11. In other wordsythesleeve 12 'is rotatably suspended vfrorn the 'pipe connection 11, thus forming 21 SWlg'lloiht; asv 'is manifest. The sleeve 12 is horizontally disposed and slidably mounted-withinl the sleeve 12 ,isn a suitable brace-rod '15, preferably made from pipe. The forw-arduend' of thefbrace-rod `15 has screw threaded 'connectionwitli one arm lof'an L-pipeclouplingllv The other," arm 18' of the coupling is directed downwai-diy.` andhas screw-threaded connection,

as at 19, with' thef upwardly directed arm`20 of the bolt`21, which bolt'is fixed tothe door 2 by means of the? nut 22.- The: screw- 'threaded connection 19v acts as 'a swing-'joint which permits thevcoupling 17 to'turn :or vrotate uponl the arm 2Q when turned in' either directioinjasismanifest.` I i 'They rear ,free end of the braceerod 15 is provided'witha cap 23'which actsas a stop whenit engagesthe rearface24cof the 4*sleeve 12. n

`In"order` tolock the vdoor 2 in. its open position, as shown in dotted lines in Fig. 1, I remploy 'af locking device consisting 4of a ,tube 25 having screw-threaded connection at` one 'end with the horizontally disposed `arm 26 ofthe sleeve 12and provided atits 'opposite end witha cap 27 having anopening 28 for the passage ,of the'locking pin 29' which is provided at its outer end with an Ieye-head 30.' `l`The Vinner end'ofthe locking p iii'29 is guided by means ofthe rperforated plug 31,l vasv show/nin Fig. 3i Encircling the piii 2'9withi`n the tube 25, is a ycoiled expair sion spring32 for automatically fforcing the inner end of the locking pin 29`into the opening'o'r passage''of thev brace-rod F15 of which there may be one or more whenever the door 2 has been opened to a point toy cause the opening or passage 33 to register with the locking pin 29. The pin 29 prevents the door 2 from being closed until it is extracted from the opening or passage 33 of the brace-rod 15.

The means I employ for lextracting the pin 29 from the opening or passage33 of the brace-rod 15, consists of a suitable chain, or cord 34: which passes over a suitable pulley 35. One end of the chain or cord is connected to the eye-head 3070i the locking pin 29, while the opposite end of the chain, or cord 34 is provided with asuitable weight 36 for keeping the slack out of the chain, or cord. The pulley 35 is swivelly supported from a suitable bracket I37 ,which is suitably fixed to Athe side wall 1 of the garage.

When the garage doors v'are closed, as shown in full lines in Fig. 1, and it is desired to open them to their open position, as shown in dotted lines in Fig. 1, the operator merely pushes, or pulls the doors 2 open in the usual manner until they assume the position shown in dotted lines in Fig. 1. When the doors 2y have reached their open position, the opening or passage 33 of the brace-rods 15 have registered with the locking pins 29'and the springs 32 will force the inner ends of the pins'` 2,9 into the openings or passages 33, thereby `Yr*locking the brace-rods from movement-in either direction, hence holding the doors from being closed by a gust of wind, `as is manifest.

When it is desired to close the doors, the operator `merely pulls down on chain 34 thereby withdrawing the locking in from the opening or passage 33 of the brace-rod 15 which permits the doors to be readily closed, as is manifest.

It is evident from thev foregoing description that I provide a device for holding hinged garage doors open, that is simple in construction, easily installed, durable and highly efficient as it is certain in its operation under any and all conditions.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains.

I do not desire to be understood as limiting myself to nthe exact details of construction and arrangement of parts as herein described and illustrated, as it is manifest that variations and modifications may be made without departing from the spirit and sco e of my invention and the terms of the ollowing claims, hence I wish it to be understood that I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claims when fairly construed.

What I claim is:

1. In combination with a garage door hinged at one of its side edges, of an L-shaped bracket screw threaded at opposite ends and provided with a nut at its lo-wer end for securely connecting said bracket to the door, a horizontally disposed brace rod having its outer end screw threaded and its inner end provided with lock pin openings, a right angular coupling having screw threaded engagement with the upper end of the door bracket and with the forward end of the brace rod to permit swinging movement of the coupling and brace rod with relation to the bracket, a sleeve for slidably supporting said brace rod, a sleeve supporting member arranged above the brace rod, a screw threaded connection between said sleeve and said sleeve supporting member to permit the sleeve to turn with relation to its supporting member when the door is being opened and closed, a cap carried at the inner end of said brace rod adapted to engage the sleeve when the door is fully open and to act as a stop for limiting the opening movement of the door, a laterally directed housing carried by the sleeve, a locking pin passing through said housing, a coiled spring for controlling the locking movement of said pin, a chain connected to the outer end of said pin, a pulley over which said chain can ride and a weight fixed to the lower end Aof said chain.

2. The combination with hinged garage doors, of a brace rod for each door having a latch opening, an angular swing joint connection between each door and its respective brace rod, a horizontally disposed sleeve for slidably 'supporting each brace rod, supporting means arranged above each brace rod, a swing joint connection between said supporting means and the sleeve for slidably supporting the brace rods, a stop cap fixed to the inner end of each brace rod to limit the outward sliding movement of the brace rods, a spring controlled latch pin carried by each sleeve automatically receivable in the latch opening of each brace rod when they register for locking the brace rods against displacement in either direction thereby holding the doors in a locked open position and means comprising a chain, a pulley and a weight Jfor withdrawing the latch pins from the latch o-penings of their respective brace rods when it is desired to close the doors.

In testimony whereof, I have hereunto signed my name to the specification.

AUGUST ERNST.
