6 Claims.

The present invention relates to an electrical door actuating mechanism and particularly to a mechanism by which the doormay be automatically opened and closed.

In the use of an electric motor for actuating a door, the provision of an automatic clutch mechanism which permits the door to be opened or shut or held in any desiredposition independently of the motor is desirable, and the principal object of the present invention is, accordingly, to provide, in an electrical door closer, a suitable clutch structure so that the door may be opened more rapidly than actuated by the motor or may be held in any position without interfering with the rotation of the motor.

The present invention also provides structure by which the motor is brought to rest when the door reaches closedposition, and mechanism by which the direction of movement of the door actuating arm is reversed so that the door automatically closed after having been opened. The invention also provides for opening the door from its closed positionby an electrical circuit controlled bya switch remote from the actuating mechanism. 7

Like reference characters refer to ike parts throughout the drawings. V

Referring first to Fig. 1, a driving motor I is secured to the frame 2 of, the device and has a shaft 3 to the end of which a gear4 is'secured.

The shaft It! has secured thereto a sleeve l5 which is held against rotation relative to said shaft by a pin IS in said shaft which engages a slot I! in the sleeve- The slot l1 permits a limited axial movement of the sleeve on the shaft and the lower end of the sleeve is provided with gear teeth l8 which engage, when the sleeve is in its lower position, with corresponding gear teeth 28 on a member 2| rotatably mounted on the shaft and supported against downward movement on said shaft by engagement with the hub of the worm gear 8.. The

member 2! is provided with bevel gear teeth 22' which engage with corresponding teeth 23 on a bevel gear 2% journaled on a horizontal stud. 25 secured to the frame.

The sleeve i5 is provided with gear teeth 26 at the upper end thereof which correspond to the gear teeth l8 above, and which engage, when thesleeve is in its upper position shown, with corresponding gear teeth 21 on a member 28 secured by a key 39 to a'sleeve 3| surround-' ing the shaft H1. The member 28 has bevel gear teeth 32 on the periphery thereof in engagement with the gear teeth on the bevel gear The sleeve I5 has an annular groove 33 in the outer surface thereof which is engaged by pins 34 and 35 on parallelly extending arms 36 and 31. Said arms, which'extend on opposite sides of the sleeve, are journaled at one end on a horizontally extending bolt 38 secured to the frame and. the opposite ends of said arms are connected to each other by a pin 43. A link 4| is pivotally mounted on the pin 40 and secured by a pin 42 at its opposite end to a vertically slidable bar 43. Vertical movement of the bar 43, which is procured by mechanism hereinafter described, positions, selectively, the gear teeth 18 in engagement'with the gear teeth 20.

The sleeve 3| which surrounds the shaft l extends upwardly from the member. 28 and throughthe bearing I 2, which engages the upper end of the member 28 for retaining said 'memher in proper position. The "sleeve 31' has an 1 annular member 44 axially slidable on the sleeve and secured against turning movement thereon by a key 45. The lower surface of the 'member V neath the gear 48 is journaleda gear 5,0having thereof. 7 V

the upper end of the bearing l2 and is accord a large diameter hub on the uppersurface The under side of the gear- 50 engages ingly held against vertical movement on the sleeve. p t p The upper end of the hub of the gear 50 is .provided with V-shaped notches 5| on qppos'ite sides. thereof for engagement with the ends of depending lugs 52 on a platej53fhaving asemi: circular recess 54 which receives the member. I Theinner edge of the plater53 engages in an annular groove 55 provided by the member 44 to'support said member and plate against rela tive axial movement. The lugs 52 project downwardly through openings 56, Fig. 4, inrthe gear 48 for engagement with the notches j5l. A

spring 5?, which surrounds thesleeve .31 between the member 44. and a collar'58,which is secured to'the upper end of thesleeve, normally holds the cogs .46; and 41", in engagement. 'A'

A vertical stud J83, Figs 1, supported by the frame has a gear-t4 journaled thereon forengagement .,Mth the gear 48. A sleeve 85 of fibrous or other frictionalmaterial surrounds the 2 V stud '03 below the gear and is held against turn-I;

The gear 48, however, is held resiliently against turning movement by the braking gear 84, the tension of the spring 86 being such that the gears 60 and BI may be turned relative to each other against the tension of the spring I6. Since the gear 48 is held against turning movement and the gear 50 is positively rotated from the gear 6| to which the arm 80 is secured, a relative turning movement between the gears 48 and 50 takes place, thereby shifting the notches 5I out of alinement with the depending lugs 52, thereby elevating the plate 53 and accordingly raising the member '44 to separate the cogs 46 and 41. The arm 80 may then be shifted in either direction or into any position desired regardless of the movement of the mem-- ber 44. When no further movement of the arm 80 occurs, the spring I6 urges the arms I and H together to re-aline the pins 64 and 65,

thereby reestablishing the original relation bea plate 95 of. insulating material mounted on the frame and said arm has a leaf spring 96 secured therein, the end of said spring engaging an arm 91 pivoted on a pin 98 on the plate 95. Said arm 97 is normally urged counterclockwise by a spring I0, and the end of said arm carries a block of insulation IOI in which a contact I02 is mounted. The contact I02, when the arm 9'! is moved clockwise by the cam 90 acting through the arm 93, engages a stationary contact I03 supported on the plate 95 and electrically connected by a strip of conducting material I04 to a screw I05 to which a lead I06 is secured. The contact I02 is connected by a resilient connector 101 to apin I08 which is electrically connected by a strip of conducting material IIO to a screw III by, which the end of a lead H2 is secured to the member II 0. The reduced portion of the cam 90 normally engages the arm 93 when the arm 80 is in the dot-dash line position Fig. 8, (the door then be ing closed), so that the contacts I02 and I03 are separated, thereby cutting ofi the power sup-1 ply to the motor I. A slight opening of the door, which involves a clockwise turning movement of the arm 80 as above stated, brings the full-size portion of the cam 90 into engagement with the arm 93, thereby'rocking said arm and the arm 97 and bringing the contacts I02 and I03 into engagement for energizing the motor I. As the door returns to closed position, the reduced portion 92 of the cam again moves into alinement with the arm 93 to permit the contacts I02 and I03 to separate under the action of spring I00. As indicated in Fig. 8, the end of the spring 96 engages the arm 91 adjacent the pivotal support thereof and procures a rapid movementof the arm 91 into or out of circuit closing position, therebyeliminating any arcing effect between the contacts.

For reversing the direction of movement of the arm 80 when the door is in open' position 'which engage pins MI and I42 on the arms I31 and again when the'door'is in closed position, the sleeve 63 carries a plate II3 having its hub II4 secured against turning movement on the sleeve by a set screw I I5. A second plate I I6 having anopeningIII therethrough to receive the sleeve 63 overlies the plate H3 and is secured against turning movement relative thereto by a screw II8 which projects through an .arcuate 1 slot I in the plate II6. Movement of said plates relative to each other provides for adjustment of the angular spacing between a radial lug I2! on the plate H3 and a radial lug I22 on the plate II6; said angular spacing between said lugs determines the extent of movement of the door.

As indicated in Figs. 1, 3 and '7, the frame 2 has upwardly'extending pins I23 which support the insulating plate 95, above referred to,'in spaced relation to the frame, and also support, in spaced relation to the plate 95, a plate I24, 20 j; the latter providing spacedguiding brackets I25 in which a bar I26, comprising a pair of flat strips. I26a. and I261) secured together, is horizontally slidable. Said bar has a projecting lug I2'I carrying a downwardly projecting pin I28 which is in alinement with the radial lugs HI and I22. The bar I26 also has a small projection I29 on theunder strip I26b which engages an. elongated recess I3 in a horizontally slidable flat bar I3I, the latter being supported on'edge by the brackets I25. The bar I26 is provided with rack teeth I32 on one .edge thereof which engage with a gear I33 journaled on a stud I34 on the plate I24. The gear I33 is in mesh with a gear 535 on a stud I36 also mounted on the plate I24. Each of the gears I33 and I has arms I3.I and'I38 respectively, secured thereto,.

and the ends of said arms are connected together by a. spring I40, the opposite ends of and I38 respectively. The spring I40 tends to retain the arms, and accordingly the gears, either in the position shown, or, upon movement of the bar I26 forwardly, Fig. 3, in response to engagement of the pin I28 with the lug I22 during clockwise turning movement of the sleeve 63, to' shift the bar I26 after the latter. reaches its mid position with the axis of the spring I40 in alinement with the axes of the studs I34 and I36 into the dot-dash line position of Fig. 3. The gears I33 and I35 actuated by the spring I40 constitute a quick throw mechanism which is operable to shift the bar I26 in either direc: tion'after the latter is moved to its mid position by the radial lugs I2I or I22.

Referring now to Fig. 6, the bar I 3I has a projecting lug I43 which carries a vertically extending pin I44 (see also Fig. 7), the latter engaging a latch I45 pivotally mounted on a pin I46 on the plate I24. A spring I4I normally urges the latch I45 counterclockwise into positive engagement with the pin I44, and said latch is provided with spaced recesses I48 and I49 connected by an arcuate surface I50. Said recesses resiliently retain the bar 'I3I either a in the position shown in Fig. 6 or in the opposite end position indicated in dot-dash lines in which position the pin I44 engages the opposite recess The lower edge of the bar I3I is provided with rack teeth I5I which engage with a gear I52, Fig. 3, on'one end of a shaft I53, journaled in brackets I54 and I55 on therframe. -The bracket I55 has a guideway I56 which receives the vertically slidable bar 43 above referred to, and the latter is provided with rack teeth I51 for en gagement-with a gear I58 on the end of the shaft 153.. Shifting movement-"ofi-the barI26 in response to engagement between the pinIZB r and either of the lugs I2I' or I22 .procures ;.a

corresponding shifting :of the bar; .Ii3 I which, through the medium of the. sha.ft*l53, procures a' corresponding: vertical movement of the bar.

43, thereby shifting .the sleeve or clutch member I5 on theshaft I0.

As above' stated, the motor" I is energi zed as 77 soon as the door is slightly open by the turning of the cam 90. The structure shown also .pro-

vides' for energizing the motor while :the door is completely closed, thereby opening the door from the closed position without the necessity fora pa'rtialmanual @opening' of theidoorr This feature is;particularly. useful in connection with apartment house I doors having an electrically controlled'latchyby which the door is unlocked Referringinow to'Figi 9, the frame 2 support a solenoid 150 mounted :on'a bracketl-IBIfFig.

'1. The solenoid is positioned beneath the'plate' 95. and actuates an armature I62 pivoted on a pin I 53' on the frame. "The armature has a re silient finger'IMextending therefrom and. en gaging adepending pin I65 secured, as shown in Fig. 1', to the arm 91. -Energization of the solenoid procures attraction; of thearmature I 62 an'd a corresponding clockwise movement of the arm 97 to bringthe contacts I02 and I03 into engagementpthereby closing the electrically.

One type of electricalIcircuit-for actuation of the door closer is shown in Fig. 10. Referring to this figure, the motor I is connected by a lead I56 through a manually controlled-switch I6] to a supplyleadISBP The other terminal of the trolled switch I13 to the supply wire I10.

motor I is connected by the lead I08; above referred to, to the screw =I05 which is electrically 7 connected to the contact I03. ThemoVable contact on'the arm 91 isconnectedthrough the I screw I II and the lead'll2 to a -supply wire I10.

' In complete automatic opening of ,the door" without the necessity for a slight manual openmg thereon the switch 1: which controls the m,

solenoid I50 is closed, energizing said solenoid and causinggattractio n of the armature I62; thereby bringing the contacts 102 and I03 into 1 engagement for energizing themotor. Sincethe door latch isreleasedot this time byany suit- 7 able well-known mechanism, the rotation of the motor I procures an opening of the door and a subsequent closing thereof in the manner above set out. As soon as the door starts-to open, the'cam so holds the contacts I02 and I03 in engagement so that the door will continue its automatic opening'and subsequent closing, even if the switch H3 is opened. 7 1

In order to have the door stay open in any adjusted position, the switch I67, by whichthe supply of power to the motor is manually controlled, is opened, thereby stopping the rotation of the motor l. Since the gearing described cannot be actuated by a turning movement of the arm 89, the latter-is held stationary and no unintended movement of the door occursregardless of the position of the door at the time.

When the switch I61 is open, so that the motor i is not rotating, the door on which the device is mounted may still be opened and closed manually. As above pointed out, when the arm 80 is rotated manually as by opening or closing of the door with the member stationary, the turning movement of the arm 83 procures a corresponding turning movement of the gear 6i and the gear 50 which meshes therewith.

Since the gear 48 is held against turning movemitted by reason of the separation of the cogs 46 and 41, the spring 16 returns the pins 64 and 65 into radial alinement, thereby reestablishing the original relation between the gears 48 and 56 so that the cogs 46 and 41 are again in engagement for a positive driving of the arm 80 from the motor 1.

While the motor is rotating and the door is held against movement temporarily, the cogs 46 and 41 are again withdrawn from engagement with each other to permit the motor to rotate without moving the door. The door is necessarily held against movement with a sufficient pressure so that the torque on the arm 80 is great enough to overcome the tension of the spring 16 to permit a relative rotation between the gears 60 and GI and a corresponding relative turning movement between the gears 48 and 5!! which, as above stated, elevates the member 44 and separates the cogs 45 and 41. The motor I may then rotate with a corresponding rotation of the member 44 without transmitting any rotation to the arm 80 until the pressure on the door is released and. the action of the spring 16 again returns the gears 48 and 50 to their original position to permit the member 44 to return to the position shown with the cogs 46 and 41 in engagement. The operation of the automatic clutching mechanism, above described, is the same when the door is manually opened or closed at a greater rate than the automatic rate of movement of said door by said motor. In this case, the increased torque on the arm 80, as a result of the manual turning movement of the door, is transmitted to the gear 59 which is turned relative to the gear 48, the torque on the arm 80 being suflicient to overcome the tension of the spring 16 so that the the positive driving engagement between the; 5

driving member 44 and the driven armBG when the torque on said arm is increased to a predetermined amount greaterthan the torque on the driving member 44 and said mechanism automatically reestablishes the driving C01'l1'l6C-51'0 tion between the member 44 and the arm 80' when the torque on said arm is decreased to the proper amount. It will be apparent that by an adjustment of i the lugs l2! and I22 and the position of the-l5 cam 98 relative to the-arm 89, the device :may be. adapted universally for opening and closing a door either inwardly or outwardly relative to the device; that is, the device maybe positioned -on either side of the door regardless ofwhich 2O direction the door opens.

The switch I13 which procures automatic opening, of, the door fromclosed position may,

as will be apparent, be actuated either bysoundresponsive means or light-responsive means. This arrangement is particularly applicable to garage doors so that the doors will be opened automatically by sounding of the horn on the automobile or by the influence of the headlights of the automobile on the light-responsive means,

the'latter being energized or activated by the lights for closing the switch H3 through any suitable mechanism such asa relay device and thus automatically opening the door.
