neon swnvs dnp'licatiqn filed December 4,v 1.922.. s xier No. 604,891..
To all whqmtr concern/91., I
Be it known that I, Lon s. scnoetaorr, a citizen of e. Un ted. S ates, residing; at Madison, in the. county of. Dane and-State of W scons n, have inventedcertainnew and useful Improvements. in. Door Swings, of whic the following, is a specificat on.
M invention relates to. deer s ing i which t e force mechanically: applied to onerate. the doors is: pivotally located; in the angle of. travel of th door ;v and; theobjects of my inv ntion are, first. to .ap-p yfthe,
power n e. angle: f rave of thefdoorz second, toprovide a su-itahle power located in the angle oftravel, which will-move-the door apart of the. d stance and then complete the movement; third,,,to, provide a suitable powerloca ed in the angle of the ra el, which while, approaching the center, will store up power to be utilized for completing the travel fourth, to provide suitable power to move thedoor the desired distance, and means for checking. th momentum and cushioning at the end of the travel; and fifth, to provide meansfor electrically con trolling the doors from; any oneof a plurality of stations. v i
I attain these objects by two methods shown in the accompanying drawings in which 1 Fig. 1 is a plan;
Fig. 2 is a front elevation;
Fig. 3 is a side elevation of the air engine;
Fig. 4 is a partial vertical longitudinal section of the same, on line A-B, Fig. 3;
Fig. 5 is a plan of the engine, on enlarged scale, connected to one door when open, and a portion of the rod 8 which connects the two doors together.
Similar numerals refer to similar parts throughout the several views.
The bracket 1, is secured above the door and an air engine 2, is pivotally connected to the base of same, and a piston rod 3, disposed within the cylinder is pivotally connected to the inner end of a lever 4, this lever swings upon a pin 5, disposed through the outer end of the bracket and is free to move in the direction of the cylinder, but obstructed in the opposite direction by a set screw 6, through the inner end of a lever 7, which also swings upon the pin 5. A rod 8 is pivotally connected to the inner end of lever 4, in the direction of the edge of the door. An adjustable link 9, is dis osed on the outer portion of the lever 7, an one end of arod 10,, is pivotally secured thereto, and the opposite end is loosely mounted on a. post 11,;Secured to, and extending upward. from the door. A, pair of extension springs 12, areanchored to, thewall above the door at one end, andextend outward 1 Onboth sides of the lever 7, to a bar 13:, which extends across theouter edge of the same andmay beseated in notches 14, as. required for obtaining the proper tension.
When using double swinging doors, thesecend door is operated. from a bracket 15, secured to the wall the. same asbracket 1, with a;v lever 16,"pivotally disposed at the outer end, said, lever is. provided with notches '14,
In. operation, valve, lever 23, is tripped by the magnet 22,'air being admitted to the cylinder 2, pushes out piston 26, which is connected by piston rod 3, to lever 4. This lever 4, comes into contact with the set screw 6, in lever 7, and is also connected pivotally to rod 8, which in turn is connected to lever l6, by the slide connection 18. The movement of'the lever 4, pushes out lever 7, and lever 16, which are connected by rods 10, to the doors 27, and 28,. This movement also elongates springs 12,. As the doors pass the central position, by momentum, the springs 12 contract pulling the lever inward as it is pivoted at 5 to the outer end of the stationary bracket 1, thereby the springs complete the movement of the doors whether in opening: or closing, for the air engine only swings the door to the center of travel, momentum carries it past thatrpoint, and
the contracting of the elongated springs will carry it thebalance ofthe way.
A meansis shown for opening and closing the inlet valve 20 in the following man ner; uponeach outward stroke of the piston 26 it meets the inner end of the curved bumper pin shaft 24 and forces it a distance in the direction the piston is traveling, thereby carrying thebumper pin 24 against the plate 23, the plate 23 meeting the stem 20 closes port 19 against admission of compressed air, and synchronously opening the exhaust port 25 and locking the plate 23 back of the latch 23* by a brass spring 22, resting against the core of the magnet 22. Therefore it is seen that by closing an electric switch any place within a circuit will energize the magnet 22 and draw the plate 22 to the magnet raising the latch 23, freeing the valve 20, which will be pushed outward by the air pressure in port 19, allowing compressed air to enter, the cylinder through the ports 19 and 21, and will push the piston outward, when it will meet the bumper pin shaft 2% and as before explained close the compressed air port 19, open the exhaust port25 allowing the com pressed air to escape fromthe cylinder 2, as indicated by the dotted line markedBO in Fig. 3, and set the latch 23 for the next operation.
Each door can be opened or closed manually without disturbing or moving any of the rest of the mechanism. When operating door 27, lever 7, moves, leaving lever l, and piston rod 8, in their original positions. When the door is closed the set screw 6, through the inner end of the lever comes back into contact with the lever 4, restoringit to its original position. Operating door 28, lever 16, moves link 17, sliding it along nut 18, thus rod 8, the lever l, and piston rod 3, are not disturbed. g
My invention primarily, was the discovery of the advantage in placing the operating force in opening and closing doors pivotally in the angle of travel of the doors, and I have shown'one method in Figs. 1, 2, 8, and l, of the drawings, and another in Figs. 5, and 6, knowing that there are other connections that may be used.
Having thus described claim.
1. In a door'swing, the pivoting of the opening and closing force in the angle of travel, by means of the combining of an air engine and springs, whereby the engine moves the door through a portion of its travel, and the springs complete the travel.
2. In a door swing, an air engine with the inlet valve electrically opened from anyone of a plurality of'stations, and contact closed, an adjustable restricting screw in theexmy invention, 1,
haust' port, to regulate compression cushioning .on the return ofthe piston, the operating force of said engine, located pivotally between afstationary bracket and the door, in the angle of travel of the door.
3. In a door swing, the pivoting of the opening'and closing force in the angle of travel, by means of an air engine, using compressed airon one side of the piston only, to move the door through a portion of its travel, and an auxiliary force to complete the travel.
In testimony whereof'I aflix my signature in the presence of two subscribing witnesses.
