REBISCHKE; 0F LITTLE FALLS, MINNESOTA GARAGE DOOR OPENNG MECHANISM Application filed March 14, 1930. Y Serialk No.v 435,848.

The present invention relates to a mechanism for opening garage doors and has for its prime object to provide a structure whereby an automobile may be run up to the garage doors and engage an apparatus which will release the garage door opening mechanism so that by backing Vthe automobile the doors will swingoutwardly and open thereby eliminating the necessity of the driver getting out of the automobile to open the doory as is the common practice.

A still further vvery important object of the invention is to provide a door opening mechanism of the character above mentioned capable of use for doors ,swinging inwardly or outwardly.

Another very important object of the invention resides in the provision of a mechanism' of this nature which is simple in its Il construction, inexpensive to manufacturel and install, thoroughly etlicient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

W ith the above and numerous other objects in view as' will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

ln the drawings: i

Figure 1 is a vertical transverse section through a garage showing the inner sides of the doors with our improved mechanism associated therewith,

Figure 5 is a side elevation of the cam` lever,

Figure 6 is a fragmentary view of the upper bolt showing the adjustable connection between the sections thereof.

Referring to the drawings in detail it will be seen that the letter A denotes a garage with a pair of doors D hingedly mounted as at 8 to swing outwardly to an open position.

On the inside of the doorway of the garage at the top thereof are brackets 5 with links 6 pivotally connected thereto. 4Links 7 are pivotally connected with the links 6 and eX- tend inwardly and are pivotally connected with links 8 pivotally engaged with brackets 9 on the doors D.`

Springs l0 are anchored on the brackets 5 and to the pivots between the links'7 and 8 and tend to normally swing the doors outwardly to open position. Y

An upperV bolt 11 is formed of a pair of sections adjustably connected together as in-V dicated at' 12so that thelength of the bolt may be changedtomeet circumstances. This boltjll `is slidable; throughfbrackets 14 on the inside of'one door Dadjacent the free edge thereof. A lowerfbolt 15 isrslidable on the inner surface of theother door D adjacent the free edge thereof and is mounted in brackets B. l ".1 y y A lever 17 is pivotally mounted intermediate its ends as at 18 on said one door D as the pin and slot connection 19 with the lower endof the bolt 11. AnV end of the lever 17 is engaged under a lateral extension 20 on the lower bolt/15.. A spring 21 normally holds the bolt 11.in` a locking position' that is upwardly `while a spring 22 normally holds the bolt 15 in a locking position that is downwardly.

Obviously by rocking the lever 17 the bolts 11 and 12 may be retracted to unlocked position so that the doors will swing open; One of the doors is provided with a slot 22 adjacent'the lever 17. 1

A bracket 2i on the outside of the door having the slot'22'pivotally supports a lever 25 having acurved cam arm 26 extending through-the slot 22 under the lever 17. A spring 27 engages with thelever. 25 to hold the` bottom eivfl thereof normally swung'outwardly. A pivoted ratchet bar 28 is on thel doorandis urged upwardly by a spring 29 into engagement with the lowerlend 'of the lever V25 to holdit in any position to which it may have beenswung.

lThe automobile approaches the doors of the garage and the bumper engages` the lever 25 pushing this lever inwardly so as to cause the cam arm 26 to rock the lever 17 thereby retracting the bolts ll and l5. The lever 25 is held in the position to which it is forced by the bumper of the car by means of the ratchet bar 28 as will be apparent. The automobile is then backed away from the door and the doors swing open to their normal position.

While we have herein shown and described our invention associated with a garage door swinging outwardly, it is to be understood that we do not wish to limit ourselves to an outwardly swinging door as obviously the invention can be used with hinged doors swinging either inwardly or outwardly.

It is thought that the construction, utility, operation and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.

The present embodiment of the invention has been described in considerable detail merely for the purposes of exempliiication since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit 0r scope of the invention as hereinafter claimed or sacrilicing any of its advantages.

Having thus described our invention, what we claim as new is:

l. In combination with a door, and devices for fastening the same in a closed condition including a roclable element, a lever, means for pivotally mounting the lever on the door, said lever having an extension projecting through a slot in said door, and normally directly engaging said rockable element, spring means anchored to the door and engaging said lever for normally urging the same in one direction about its pivot, a rack bar pivotally mounted on said door and spring means impinging against said rack bar for retaining said lever in a predetermined position against the action of said first-mentioned spring means.

2. The combination with a door having a slot, of door fastening elements carried by the door, an actuating lever for moving said elements to a door releasing position, means for pivotally mounting said lever on said door, spring means normally urging said lever in one direction for releasing said door fastening element, a rack bar pivotally mounted on said door, and a second spring means urging said rack bar into engagement with one end of said lever for retaining the same in a predetermined position, said lever being capable for engagement with a vehicle whereby the lever may be moved by the vehicle out of engagement with said lever.

3. A vehicle actuated latch control means for the latching elements associated with a garage door, comprising a lever pivotally mounted on the door and having an offset longitudinally curved end portion projecting through a slot in the door for engagement with a movable part of the door latch means, a spring member interposed between the free end of the lever and door for normally spacing said end of the lever relative to the door, a rack bar pivoted at one end to the door, and a spring element anchored to the door and engaging the rack bar for urging the latter into engagement with said free end of the lever for retaining the lever against movement under the expanding action of said first-mentioned spring immediately subsequent to a contraction or eXpansion of said first-mentioned spring.

In testimony whereof we afliX our signatures.
