AUTOMATIC DOORl-OPRATIN G MECHANISM.

Specication of Letters Patent.

Application led December 27, 1910. Serial No. 599,435.

To all whom t may concern.'

Be it known that I, ROBERT HOPE-JONES,

in the count of N'- `agara and State of New York, have invented certain new anduseful .Improvements in Automatic Door-Operating Mechanism; and I do hereby declare the following to be a and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon. v

The present invention has for its object to provide a mechanism for automatically operating doors and-adapted particularly to be used in connection with multipanel revolving doors, whereby the latter maybe caused to move in advance of the operator.

A further object of my invention is to p rovide an operating or driving mechanism adapted to operate intermittently and con` trolling devices therefor actuated by the operator for setting said mechanism into operation or arresting it, as may be required.

To these and other ends the invention consists in certain improvements and combinaparts all as will be hereinafter more fully described, the novel features being pointed out inthe claims at the end of the specification. l .In the drawings: Figure l is a side elevationy partly-inv section of a revolving door provided with operating and controlling mechanism constructed in accordance with my invention, Fig. 2 is a top plan view thereof; Fig. 3 is a detail diagrammatic the circuit larrangement of the controlling mechanism; and Fig. 4 is a sectional view taken on the line IX-4* of Fig. 1,l showing one of the contact making members.

lower end in ra ity. .of panels, dicated .by A,

doors lradiate from a central shaft G on which theyare supported, said shaft being ournaled near its upper end and at the the top H and the bottom I of the casing. In the operation of doors of this and arrested are mounted upon the top H Fig. 2. The several character a person stepping into the casing at one side or the other pushes the door or panel immediately in front of him, such as the door A or C, causing all of the doors to revolve until the particular panel which is ahead of him passes beyond the segmental side of the casing and rovides an exit space. In the construction o doors of this character it is customary to employ four panels which are arranged at right angles to each other and in order to provide ample space for the accommodation of an adult person and permit him to walk through the casing and use his normal length of step, it is necessary to make the doors of considerable Width and in order to obtain a substantial structure, the doors are necessarily quite heavy. It is also customary to provide the doors with plate glass panels and in many instances, especially in the more ornamental structures, the frame work or sash is made wholly of metal, consequently the structure as a Whole is ponderous and somewhat dificult to operate, especially if the door is in position of rest and each person desirin to pass through the doorway is require to start it in motion.

To facilitate the operation of the door, so that it may be rotated -intermittently at the volition of the operator, I have provided an operating mec anism which will be actuated whenever he attempts to push a dooi ahead of him and the controlling devices by which the driving mechanism 1s started so arranged that the door or doors will continue to revolve as long as the operator follows it in the direction of its movement and exerts a slight pressure upon the operating member. The controlling devices also embody an arresting memI ber which is thrown into operation in the event the person operating the door should halt or so retard his movement that the door following him engages a In carrying out my invention I have of the door casing a driving mechanism consisting of a worm 1 and a gear wheel 2, the former being driven from any convenient source of power,: preferably an electric motor, indicated by 3.

he gear wheel 2 is journaled loosely upon the upwardly projecting end of the vertical door shaft G and imparts rotary movement thereto 'in one direction by means of a ratchet wheel 4 keyed to the shaft with portion of his body.

which a driven connection is maintained by means of a spring operated dog or pawl 5, this connection causing the doors to be moved in one direction and also permitting them to move in the same direction at an increased rate of speed, should an operator impart momentum to the doors greater than the rate of speed at which they may be operated by the driving devices. Also mounted on the shaft Gr and rigidly connect- -ed thereto is a brake wheel 6 encircled by a brake band 7, one` end of which is connected, as indicated at 8, to an arm 9 of a bell crank lever 11, its opposite extremit 10 being attached to an arm 9i of the ell crank lever whiclnispivoted. at 12 to the bracketl cured to the shaft G is a disk 17 of insullating material provided on one of its faces with concentric collector rings 18, 19 and 20 with which respectively engage wipers or brushes 21, 22 and 23 pivotally supported in stationary brackets 24, 25 and 26 secured to the top H of the door casing. The shaft G is preferablyl tubular and passing down' vvardly therethrough are the conductors 18", 19x and 20X fromeach 'of which leadva plurality of branch wiresconnected to the contacts controlled by the operating and arresting plates or ,members mounted on the several door panels, as will be further described.

Arranged on the rear face of each dooror panel is the operating member or push plate,

indicated in the diagrammatic illustration Fig.` 3 by the reference letters A', B, C and D. In the forward face of each door is a similar plate which maybe located at any desired position to engage some portion of the body ofa person with which it may be brought into contact, but. preferably arranged at the lower or bottom edge of the door in such position -that 1t may be actuated byfengagement with a persons heel in the event their step is faulty or retarded. In Fig. 3 these arresting members are lndicated by A2, B2, Czand D2. The detail construction of the members just referred to is shown in Fig. 4. The operating members or push plates are preferably arranged in recesses in the rear faces of the doorpin which they Vare yieldingly supported by springs 27 normally tending to project them into engagement with the overlapping edges of' the stop plates 28. Within the door re` cessis a block 29 of insulating material through the center of which passes a stud 30 in electrical connection with a leaf spring in the present instance.

having the ends 31 and' carrying insulating studs 33, 34, and adapted to engage the vcontact points 35 and 36 which are als'osup- From ported on the insulating block 29. this arrangement of the parts it will be seen that slight pressure applied uponthe plate or member A will move the latter inwardly against the tension of either or both of the springs 27 permitting the contact spring at one or both ends to engage the contacts 35 and 36. Thepush plateV may be guided upon studs or pins, as indicated at 37.

`The push plates just described are adapted to close the circuit of the door operating motor either directly or by closing an auXiliary circuit provided With an electromagnetic device for causing the operation of the motor, the latter arrangement being shown On referring now to the diagrammatic figure of the drawings, 1 have there illustrated the duplication of various contacts referredto in the descrip'- tion of Fig. 4 as they appear on the several door panels and in each case-they are indicated by the numerals before applied, but each of these is supplied with the proper exponentl a, b, c, orV d, according to the particular panel A, B, C` or D on which the parts are respectively located.' 1n this illustration-it will be seen that the conductor 18x is connected by the wires 180,' 181, 182 and v with the contacts 35-36,

183 respectively,

of .the sets lof normally openvcontacts operated by the sev- Current for operating the motor 3 be obtained from any suitable source supplied over the line wires X and Y,I and interposed y in the circuit between the source supply and the motor is a normally open switch comprising the contacts 40 and 41, the latter being mounted on the switch4 arm`42piv'oted on .the binding post 43 and retracted into inoperative position by a spring 44. Leading from the line wire Y to the contact 40 is a conductor y and from the binding post 43v to one ofthe brushes of the motor 3 is'the conductor y which is continued fromxthe other brush of the motor, as indicated at 2, to a contact ys which is normally engaged by aspring contact plate y* carried by the brake operating lever 13. The contact plate yi isconnected to the linewire X by the conductor w.- l

The switch arm 42 for closing the motor circuit is actuated by the magnet or solenoid 45, the armature or core 46 of which is con-- nected to the switch arm 42. One terminal, of ythe solenoid 45 is connected to the line wire Y by a conductor m2 and from the othei tacts on the doors are,

terminal thereof a conductor w3 leads to the brush 21, which bears on the ring 18. The line wire X is connected by a conductor m4 to the brush 22 which bears on the ring 19. The conductors 1 v#519" leading to the conas previously described, connected to the collector rings 18 and 19,' fromV this it will be seen that the solenoid 45 isl arranged in a circuit comprisi g all of the various sets of contacts, so that it may be energized by pressure upon vany one of the push plates, as will be understood.

The energizing of the solenoid 45 effects the `operation of the switch L12 and the closing of the motor circui .The operation of the mechanism so far described, will now be clearly understood. A

If pressure on the arresting plate is removed the circuit through magnet 15 is'broken, permitting the spring 16 to release the brake and close the motor circuit at the contacts ya, yt, thereby continuing the motion of the door. main switch 50 is interposed in the main liney to shut ofi the current in case of any failure of the controlling mechanism to operate properly, in which eventthe ratchet 5 will permit the doors to be rotated in the usual .mannen Door operating mechanism'construc'ted in accordance with my invention, is simple in 'construction and consists of' few parts which structures of the maybe readily applied to are now in use.
