To (tZZ xix/mm, it may concern.-
Be it known that I, GEORGE N. PARKER, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Electric Door- Strikes, of which the following is a specification, reference being had therein to the accompanying drawings.
My invention relates to improvements in that class of devices known as electric dooropeners that are generally applied to the main doors of flats and apartment-houses, and which are adapted to be actuated to unlock or release the latch of the door by the energizing of an electromagnet located within the door-frame and connected by suitable electric circuits with one or more distant points, as from the different rooms or apartments in the building, in which are placed push-buttons or equivalent circuitclosers for controlling and operating the door-opener which releases the latch and allows the door under pressure from a spring to be swung open.
The invention consists in the combination of elements and in certain parts of construction entailed in the combination of said elements to obtain the desired result.
A full understanding of, the invention can best be given by a detailed description of a preferred construction embodying the various features of the invention, and such a description will now be given in connection with the accompanying drawings, and I attain my object by the mechanism there illustrated, showing such preferred construction, and the features forming the invention will then be specifically pointed out in the claims.
In the accompanying drawings, Figure 1 is a front elevation of the electric door-opener. Fig. 2 is a side elevation of the door-opener with the latch block or keeper pressed back. Fig. 3 is a rear view of the front plate of the casing. Fig. 4 is a transverse section of the same on the line 3 3 of Fig. 3. Fig. 5 is a side elevation of my electric door-opener with part of the casing removed. Fig. 6 is a section on line 6 6 of Fig. 5.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The invention here shown has only to do with that part of an electric door-opener located within the door-frame, and when set up within the frame the only parts visible would be the front plate a of the casing cl and the latch block or keeper 1* and contiguous parts which are in the recess or slotted portion m of the plate a. The door-frame is cut away or mortised to admit the casing d, and the front plate a should be inserted sufficiently to be flush, or substantially so, with the front of the door-frame, and the escutcheon y, attached to the side of the frame by screws or other suitable means, will be flush, or sub stantially so, with the side of the door-frame.
The plate a is provided just above the recess m with the elongated opening I; for receiving the bolt of an ordinary look. It is frequently desirable in apartment houses that night-locks be used, and for this reason I use a compact and simple electric dooropener, to the inner back of the frame of which is secured an electric magnet of the ordinary form, which runs parallel with the sides of the frame, and having the front plate provided with the opening I) and the screwholes 0. The plate a is recessed or cut away from one side nearly to the opposite side, and the sides of said recess, beginning at their outer edge, are inclined rearward, as at n, and an inclined surface Z of the plate a connects their inner edges, which inclined surface Z extends across the inner edge of the recess m.
The casing d is attached to the front plate a by screws 'L, inserted through the scre\ -holes h of the raised portions a. (See Fig. 4.)
The front plate a is recessed, as at n, to allow the free ends of the arms 8 full play when not resting on the armature of the magnet.
In the electric door-opener which I use these arms 8 are pivoted near their notched ends. The armature t is pivoted at its lower end upon the pin it and is provided with the back-stop or buffer or to keep it within magnetic distance of the magnets to u. The armature is normally kept away from the magnets u and u by the spring 12. (Clearly seen in Fig. 6 of the drawings.) A yoke 7" when thrown forward by a spring w of any suitable kind allows the arms 8 to be thrown forward, so that the studs 1*, projecting outward from each side of the yoke 1', will engage in notches s in the arms 3 and tilt them'for Ward. As the arms 8 are tilted forward the spring 1) forces the armature away from the magnets a a; but when the armature is drawn up, so as to release the arms 8, then the door can be easily opened, as the door-latch will readily tilt the arms .9 past the armature t and allow the door to open.
In the yoke 1", I use a series of balls 0, which extend partly outward through recesses in the yoke r, and as this yoke is pivoted at an an le to the line of motion of the door-latch, yie ding readily to the pressure applied to the latch, the balls allow easy motion and prevent catchin of the latch; The yoke immediately bac of the portion containing the balls 0 is grooved or hollowed out, as at g, to receive the latch, and the inclined surface Z of plate a acts as a buffer and prevents the latch from striking the rear wall of the casing (1.
Through the rear side of the casing d extends the two binding-posts e, of insulating material, to the upper one of which is attached a circuit-wire f and to the lower one is attached the other circuit-wire 9, said binding-posts being set in the rear side wall of the casing d and are attached on their inner side by wires to the magnets.
Having thus described my invention, I
claim as new and desire to secure by Letters Patent 1. In an electric door-opener, a frame having a front plate provided with a latch-recess having inclined edges extending rearward from the three sides of the recess, and provided with an elongated groove above the recess for receiving a lock-bolt, ayoke having outward-extending studs, notched arms pivoted between the yoke and the inner sides of the frame and engaged by the studs, and an electromagnet and its armature within the frame, substantially as shown and described.
2. In an electric door-opener, the combination with a frame and a yoke r, of a series of balls rotatably held by the yoke for a striking-surface, a series of arms pivoted between the yoke and the walls of the frame, and studs extending from the yoke into the arms, substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
GEORGE N. PARKER.
