AUTOMATIC DOOR-OPERATING MECHANISM.

To all whom it may concern:

Be it known that I, EDWARD A. BACHMANN, a citizen of the United States, residing at Fort Atkinson, county of Jefi'erson, and State of lVisconsin, have invented new and useful Improvements in Automatic Door- Operating h Iechanism, of which the followmg is a specification.

- erence to the accompanying drawings, in

which- Figure 1 represents a vertical section of a portion of a garage, showing a side View of the mechanism through which motion is communicated from a moving vehicle to the doors of the building. Fig. 2 is a front view of a garage, showing the doors closed in connection with the door operating device, which device is diagrammatically shown, and Fig.3 is a plan view of the device also shown in part diagrammatically.

Like parts are identified by the same reference numerals throughout the several views.

While my device is adapted to be used in connection with other classes of buildings and operated by the movement of other vehicles, for brevity of description the device is referred to as being adapted to be operated by a moving automobile for opening and closing garage doors.

1 represents a portion of a garage and 2 represents the front doors which are adapted to be automatically opened and closed by the movement of an automobile. The doors 2 are adapted to be suspended from the track 3 by hangers 4: of ordinary construction, which hangers are provided with rollers 5 adapted to run backwardly and forwardly on said track as said doors are opened and closed. The doors 2 are adapted to be drawn open by the cables 6 which are preferably connected with the upper ends of said doors by the hangers 4, and extend Specification of Letters Patent.

from thence over the pulleys 7, 8, 9 and 10, and are connected at their opposite ends with the front end 11 of the sliding carriage 12, while said doors are adapted to be drawn toward each other in the position shown in action of the cables 13, which cables 13 pass over the pulleys 13 H, 15 and 1.6, and are connected at their opposite ends with the opposite end 17 of said carriage 12. Thus it will be obvious that as the carriage 12 is moved toward the garage, said doors 2 will be thrown apart and opened, and while the carriage is moved in the opposite direction, said doors will be closed. The carriage 12 is adapted to be moved forwardly by an approaching automobile, one of the'axles of which is adapted to contact with the vertical arm 18 of said carriage, and said vertical arm is retained ina vertical position so as to be broughtinto contact with the axle of the automobile as the latter approaches the same in either direction, by the engagement of the upper ends of the dogs 19, 19 with the shoulders 20, 20 connected with the lower end of said being pivotally connected 12 by the bolt 21. When, however, the carriage 12 has been moved-forwardly by the automobile far enough to have caused the doors 2 to open, the front end of the bracket 22 is adapted to contact .wit the lug 523 formed on one side of the rear dog ,19, whereby said dog is thrown out of engagement with the opposing shoulder 20 0' said arm, when said arm is released and permit ted to turn rearwardly upon its pivot 21, whereby the automobile is free to pass over the carriage 12 Without further When the automobilehas passed over the carriage 12, the arm 18 Will be drawn back to its vertical position by the spiral springs 24, 24, which springs are connected at one of their ends with said arm, and at their opposite ends to the side of the carriage 12. 'The dogs 19, 19 are normally retained in place against the shoulders 20 by the spiral spring 25, the respective ends of whic spring are connected with said dogs respectively, said spring being adapted by its recoil to bring the upper ends of said dogs toward each other and against the upper sides of said shoulders.- Th lower ends of said dogs 19 are pivotally connectcarriage 12 by the wit-h the carriage arm, the lower end of said arm ill supporting pivotal bolts 26, 26. 27 is a'track upon which said carriage 12 is adapted to'move toward and from the garage.

It will now be understood that as an automobile app'roachesthe doors 2, said doors will be thrown apart through the mechanism described, whereby the automobile is free to ass said doors 2, when the front 1 axle of tie automobile is adapted to contact with roller bearings 31, 31 b tension of said s rin s bein substantiall r P f g 3 t ti;

.original position. When 28 of the carriage uniform, whereby sai standard is normally retained, as shown, in a vertical position. The lower end of said standard is rovided with a. air of laterally projecting s oulders 32, 32 or engagement with the upper ends at the respective dogs 33, 33, and said dogs are pivotally supported at their lower ends from the sides of said carriage 29 on the pivotal bolts 34, 34. It will now be understood that as the automobile is drawn into the garage and against said vertical stand ard, as stated, said carriage 29 will be carried forwardly by the movement of the automobile until the stationary bracket 35 is brought in contact with the lug 36 formed on one side of the rear dog 33, whereby the rear dog 33 will be thrown out of engagement with the rear shoulder 32, thereby releasing said vertical standard 28 when the autagmobile will be free to pass over saidcarriage 29 without further moving the same. As the carriage 29 is thus drawn rearwerdly by the action-of theautomobile, motion is communicated therefrom through the cables 3? and 13 to. the front edge of said doors, 2, whereby said doors are drawn together and closed in rear of the automobile, while by the same movement of said rabies 37 and 13 by which said doors are drawn together, the carriage 12 will be drawn. back to its the automobile has thus passed over the vertical standard 29, said standard will be brought back to its vertical position by the recoil of said spiral springs 24, when it will be retained in such position by the action of the dogs 32, preparatory to sing acted u on againby the movement of the automo ile as the same is withdrawn from the garage. As the automobile is moved outwardly above the carriage 29, one of its axles is caused to contact with the front side carriage of the vertical standard 28, whereby the carriage 29 is caused to move rearwardly again by the movement of the automobile,

and 'whereby movement is communicated from said carriage 29 to said doors 2 through the cables 38 and 6, which cables are connected with the'outer edges of said doors, whereby said doors are separated and opened preparatory to permittin the automobile to pass from the garage. Vhen the carriage 29 has moved forwardly a short distance, the rear end of the bracket39 is brought in contact with the lug 40 formed upon one side of the rear dog 33, whereby said dog 33 is brought out of en agement with the lugs 32 and whereby said vertical standard 28 is free to be inclined forwardly, thus permitting the automobile to pass over said 29 and from thence out through the doors which have previously been opened. By the forward movement of the carriage 29, last described, motion is communicated therefrom through the cables 38 and 6 to the other carriage 12, wherebysaid carriage12 is drawn toward the gara e preparatory to being again acted" upon y the moving automobile. As the automobile moves outwardly over the carriage 12, the

front axle is again brought in contact with the opposite side of said vertical standard 18, said standard being retained in a. rigid vertical position in connection with said carriage 12 through the action of said dogs as previously described, whereby said carriage will be caused to move rearwardly with the automobile until the doors 2 have been again closed When the doors 2' have been thus closed behind theautomobile, and the carriage l2 hasbeen thus carried outwardly away from the garage, the bracket whereby said dog is brought out of engagement with the 0 posite shoulder 20 of said vertical standar when said standard is re- 38 is caused to contact with the lug 39 formed upon one side of the front dog 19,

leased and permitted to be inclined forwardl by the action of the automobile axle,

where y the automobile is free to a ain pass over said carria e 12. Thusit wi 1 be obvious that by the orwardand backward movement of said carriages 12 and 29, said doors 2 are automatically 0 of the approaching automo He and closed in rear of the same as it enters the garage. Also that said doors will be opened in front of the'automobile and'closed in rear of the same as it passes from the garage.

Having thus described myinvention,what I claim as new, anddesire to secure'by Let- .ters Patent isk 1. 'In a device of the described class, the combination of a pair of slidable doors, a pair of reciprocating carriages, flexible con nections communicating between the respective ends of said reciprocating carriages and ned in front I said doors, pivotall connected witheach 0 sad carriages, means connected with said carriages for normally retaining said standards in a vertical position, a carriage supporting track for each of said carria es, and means connected with said track or automatically releasingsaid vertical standards as they approach the limit of their movement in either direction.

2.' In a device of the described class, the combination of a' pair of .slidable doors, a pair of reciprocating carriages, a cable'connected between one end 0 said carriages and one side of said doors, adapted as said carriages are moved in one direction to open I zsaid doors and as said carriages are moved in combination of the. opposite direction to close the same, a standard pivotally connected with each of said carriages, means connected with said carriages for normally retaining said standards in a vertical position, a carriage supporting track for each of said carriages, and means connected with said track for automatically releasing said vertical standards as they approach the limi of their movement in elt er direction.

3. In a device of the described class, the a pair of slidable doors, a pair of reciprocating carriages, flexible co nections communicating between the respective ends of said reciprocating carriages and said doors, whereby said doors are auto.-
