JOSEPH LOOH, OF BROOKLYN, NEIV YORK.
ELECTRIC DOOR-OPENER.
Specification of Letters Patent.
Patented April 30, 1907.
Application filed Aprill7,1906. Serial No. 312,198.
To In whom it may concern:
Be it known that I, JOSEPH Loon, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Electric Door-Openers, of which the following is a specification.
This invention resides in certain features of construction by which a simple structure is obtained and one which when released will not prematurely re-engage.
This invention is set forth in the following specification and claim and illustrated in the annexed drawing, in which:
Figure 1 is a side elevation of a door opener embodying this invention. Fig. 2 is a view like Fig. 1 with p arts in a different position. Fig. 3 is a section along w w Fig. 1. Fig. i is a section along a; (E Fig. 1. Fig. 5 is a section along y 1 Fig. 1. Fig. 6 is a section along .2 2 Fig. 1. Fig. 7 shows a detent or dictator. Fig. 8 shows the armature.
A casing a adapted to be set in a door frame is shown with a catch or bolt 1) swinging on pivot c. A spring (Z returns the latch or bolt 1) to engaging ,or locked position. The catch has an arm or tail to which at e is pivoted a slide or connecting piece f. This slide pivoted to the bolt connects the bolt and a lever g. Said slide straddles the lever or its fulcrum part 7L and can slide on but rotates with the lever. The slit in the connection f has parallel or straight edges Fig. 5, and said connection straddles or slides on a similarly shaped part on the lever fulcrum. A sliding non rotary connection is thus made between the parts f and h.
The free end of the lever 9 can be locked or engaged by an armature i and when so locked the bolt 1) is held against motion by the connection f straddling the fulcrum ft of the locked lever g. When the armature is attracted or in other words when the magnet it has been energized, the lever g has been released and by a push or force suitably applied to and rocking the bolt Z) and its tail the slide f is caused to slip along or across the fulcrum it but without losing engagement therewith.
The armature comprises four lugs, namely the two hinge lugs 'i for hinge pin m, the stop lug i and the locking lug i The looking lug engages the lever 9 when looking the same.
When the armature is attracted by the magnet Fig. 2 the lug or look part i is moved to releasing position and the lever g is now free to turn or swing for the bolt 1) to be moved or swing to opening position.
To the armature at 0 is pivoted a detent or what might might be called a dictator comprising a stop or detent face p and a tail or releasing piece Q and a second tail or armature piece 1. The detent is shown in Fig. 7. When the armature i is attracted by the magnet the tail 7'' is likewise attracted and as the armature i moves to the magnet the face 2) of the detent comes to rest on a rib or shoulder piece 8 (Fig. 2) of the casing. If now the electric current is interrupted or the magnet It deenergized the armature i or its lock part i" is nevertheless held back or clear to leave the lever g and bolt b free to move or the door to be opened. The detent p is noticed in Fig. 2 holding the armature i clear.
As the lever g swings back with the opening bolt such lever impinges or presses on the swell or curvature at the free end. portion of tail Q and the detent is thus rocked about pivot 0 a sufficient extent to slip face p off the ridge or lug s from the position shown in Fig. 2 to that of Fig. 1. The armature i is now free and its spring or blade 25 moves such armature back for its locking lap i to be in position to again engage lever g.
The lock lap i is beveled in one direction to allow the lever g to retrrn to closing or looking position but said lever 9 cannot open until armature i has moved to releasing position.
I claim:
1. In an electric door opener, a magnet, an armature, a lever engaged by the armature, and a strike and a slide pivoted to the strike and made to straddle the fulcrum of the le ver for connecting the strike and lever.
2. In an electric door opener, a magnet and armatrre, a lever engaged by the arm ature, a strike, and a slide pivoted to the strike and made to straddle the fulcrum of the lever.
3. In an electric door opener,-a magnet and arm at re, a lever engaged by the arm ature, a strike and a connecting piece pivoted to the strike and made to slide on and nonrotatively engage the lever.
4. In an electric door opener, a magnet, a strike controlling the armatrre, and a dictator or holding device for the arnvatrre to hold sich armat re in releasing position with respect to the strike.
5. An electric door opener, comprising a magnet, a strike controlling armature, a holding device to keep the armature retracted With respect to the said strike, and a rib or stop for the holding device.
6. In an electric door opener a magnet,a Strike controlling armature, a holding device actuated by the magnet adapted to hold the armature in engagement With the poles of the magnet, and a rib or step for supporting the holding device when holding the magnet in disengaging position.
7. A door opener comprising a magnet, an armature and holding device both within the field of the magnet, said holding device adapted to hold the armature in engagement With the poles of the magnet and a strike engaged by the armature.
8. A door opener comprising a magnet, an armature, a holding device pivoted to the armature and attracted by the magnet, said holding device being adapted to hold the armature in engagement with the poles of the magnet and a strike engaged by the armature.
9. A door opener comprising a magnet and i armature with a holding device having an ar mature tail or portion. attracted by said. m agnet said holding device being adapted to hold the armature in engagement with the poles of the magnet.
10. A door opener comprising a strike and lever, an armature for ei'igaging the lever, and a holding device for the armature having a releasing tail or arm, said holding device being adapted to hold the armature in engagement with the poles of the magnet.
11. A door opener comprising a strike and lever, an armatrre for engaging the lever, and a holding device for holding the annatrre in engagement with the poles ol the magnet said holding device having a releasing tail or arm, said releasing tail being placed in the path of the lever, to move the holding device to releasing position by said lever.
In testimony whereof have hereitnto set any hand in the presence of two subscribing Witnesses.
