DOOR OPERATING- AND CONTROlhLmG ltfiEfilR'ANl'Sll/L adras.

To all w/ wmz't may concern: I

Beit known that L'Cimrsr ANnnRsoN, a citizen ,of the United States, residing at Two Harbors, in' the county of Lake and State of Minnesota, have invented 'certainnew and useful Improvements in Door-Operating and Controlling Mechanisms, of which the following is a, specification, reference being had.

therein to the accompanying drawing. Y

My invention relates to improvements indoor operating and controlling mechanisms the primary object of which is to provide a simple and inexpensive device whereby a door may be opened-or closed from any desired point apart from the'door itself.

Another object of .the present improvement is to construct a device whichi's adapted to be operated at a point any desired'dis tance from the door'to which it is applied and unlatch the said door and either'open it or close it.

My present invent-ion, is applicable to nearly any form of swinging door, yet it is intendedto be applied more particularly to doors such as are 'found in depots, hotels, or publiclouildings where many people are- 7 passing out, and is especially adapted for the. use of those persons who are heavily burdened, such as with two satchels' or bundles of any sort where the turning of a knobto unlatch'the. door and push it, frequently occasions the resting'of one or both burdens. I

The device may be used to good advantage in connection with furnace doors where it is desired to keep the door open but a very 2 is a top plan view of the door and door operating portion of the device showing a part of the door frame'in section.

Referring now to' the drawings in detail in which like reference numerals designate similar parts, 1 represents the door shown in- Fig. 1 in closed position and adjacent the side of the door frame 2. The door in.

' this figure is shown latched anda catch bolt 3 of the lock is shown mounted upon or within the door. It is not considered neces Specification of Letters Patent.

tending bracket plate is made preferably of metal and formed with a base portion 7 arranged right .anglesthereto and integral mounted upon the shear arm 19 at .16, the lower end of the rod 17 being pivot- Patented July 63, ltti ltttw Application filed December 9, 1914. Serial ."tl'o. 576,316.

sary to illustrate any particular term ct look, as it is well known that there are great many varieties of door locks comprismg a hor zontally reciprocal belt which springs into an opening within the door frame when the door is closed. lntlie illus tration here the opening in the door frame into Which-the reciprocal bolt 3 of the door 1 moves is numbered 4: and is protected in the door frame by the usual escutcheon platel5.

Referring now to-my improved operating and. controlling device, a horizontally ex- 6 is provided which therewith. This portion provides means whereby the bracket 'is securely fixed to the door frame 2 by means of screws 8. The portion '3" is 'arranged so as to be directly opposite the recess 4t in'the door frame into which the bolt. '3 of the door lock reciprocates. A tubular housing 9 of either round or rectangular cross section is carried by and integral with the base portion 'l' of the bracket 6. This tubular portion er tends on'each side of the base portion 7, the inner end of which tubular portion communicates with the recess it in the'door frame. A'trip bolt 10 is reciprocally mounted within this tubular housing 9. The means for reciprocating the trip bolt 10 comprises shear arms 11 and 12 which are pivotally connected at 13. The other end of the arm 11 is pivotally connected to the trip loolt 10 and the other end of the shear arm 12 is ,pivotally mounted upon the bracket plate 6 at the point 14.

The means for trippingthe bolt consistsof an operating device apart from the door and comprises a rod 17 which is pivotally the point ed to a vertically reciprocal. rod 18 at the point 61. The lower end of the rod 18 is designed to extend down through the floor .20 and is pivotally connected at 21 to the arm 22 of a bell-crank lever 23. The epposite arm 2% of this bell-cranklercr 23 ispivotally connected at 25 to a rod 26. The

bell-crank 93 is pivotally suspended in a opposite end' of the rod 26 is pivotally attached at the point 28 to the arm 29 of a second bell-crank 30 which is pivotally sussuitable dependingbracket 27 securely at tuched to the under side or the floor 20. The

ire

3 pended at 31 upon a depending bracket 32,

also attached to the under side of the floor 20. This bracket may be placed at any desired distance from the door and door frame and the rod 26 may be of any desired length and, 1n fact, a wire line or chain might be used in place of the rod and made to lead oversuitable pulleys and thereby connect this bell-crank directly to the end of the rod 18. The'other arm 33 of the bell-crank is pivotally connected at 34 to the lower end of a pitman 35 which extends upwardly through a suitable hole 36 in the floor 20. This pitman extends above the floor a suflicient distance to be readily accessible to the foot of the operator for depressing the'same and thereby release'the latch 3 as will be more fully hereinafter pointed outand also open the door by means hereinafter to be described. i

A liasp 37 is pivotally mounted at 38 adjacent the upward protruding pitman 35 whereby the pitman may be retained in its depressed position when desired by slipping the end of the hasp over the end of the pitman after the latter has been depressed and this operation be readily accomplished by the otherwiseidnoccupied foot of the oporator.

' The means for opening the door comprises a mechanism attached to the upper end of the vertically reciprocal rod 18. The upper end 39 of this rod 18 ispivotally connected at 40 to the arm 41 of a bell-crank 42 which is pivotally supported at 43 upon a bracket 44 securely fixed tothe inner face of the door frame 2 and adjacent the upper end of the door 1 for the purpose hereinafter to be described. .The opposite arm 45 of the bell- Zcrank 42 is pivotally connected at 46 to a horizontally reciprocal rod 47 which extends through a suitable hole48 in the door frame to a point approximately opposite the middle of'th'e door. At this point the end of Ithe rod 47 is pivotally and longitudinally loosely connected to the short arm 49 of another bell crank '50 which is 'pivotally mounted in any suitable manner at 51 .upon or within the horizontal wall or cap of the 'door frame. In the present case I have illustrated it pivotally mounted within a recess 52 formed for the purpose.

The long arm 53 of the bell-crank extends horizontally to a point approximately opposite the hinge of the door where 1t 1s pivotally connected as at 54 to one end of a 7 rod 55, the opposite end of which rod is pivotally connected at 56 to the upper edge of the door 1. The point of connection with the door and the rod 57 I prefer to be the center of the door as-this point of connection will give the most desirable motion to x the door when operated upon.

The connection of the rod 47 with the arm i9 of the bell-crank 50 is made flexible or loose longitudinally the rod'by means of a pivotal pm 57 being mounted within a horizontal slot 58 formed within the end of the rod 47. A flexible connection is provided .the door, thus permitting the bolt 10 to be thrust inwardly sufficient to force out the bolt 3 from its engagement with the door frame and therebyunlatching the door just prior to its being acted upon by the continued movement of the rod 47 when it engages the crank 50 and through the mechanism hereinbefore described act upon the door to open it.-

The means'for closing the door after the foot of the operator has been released from the pitman 34 comprises a' spiral spring 59 which is attached in any desired manner to the rod 18 as by means 'of the member 60 which is here illustrated as being pivotally attached at the point 61. The other end of the spring 5.9 may be attached to the bracket 44 by means of a suitable hook 62 or any other convenient means. The sprin 59 being normally contracted, it is evident that the mechanism will thus be held in the inactive position illustrated in the drawings, but when pressure is applied to the pitman 35 and the door then unlatched and swung open against the spring 59 as soon as the pressure is removed the said,spring will restore the mechanism and door to its ori inal position. Upon the return motion the 'momentum of the door together with the spring will always be sufiicient to perform the final act of closing, at least sufiicient for the bolt 3 to assume its proper position in the recess 4 of the door frame. As is evident, the entire mechanism is designed to be installed within the wall of the building adjacent the door frame, and entirely out of sight except the rod 55, the upper end of'the pitman 35 and the hasp for the same.

It is apparent from the dbove description that I have provided a device which by one movement of the foot or hand of the operator (if thepitman 35 were sufiiciently extended) the door may be unlatched and swung'open from'a point any desired distance apart from the door.

Having thus fully described my invention what I claim and desire to secure by Letters Patent isi 1. A door controlling and operating device comprising a" right angular bracket having one of its legs secured to the doorframe, said leg'having a tubular portion extending through the door-frame and its inner end adjacent the latch bolt oil the door, a member reciprocally mounted ithin the said tubular portion, two levers piv-' oted together, 'one end of one lever pivoted. to the reciprocating member and one and or a the other lever pivoted to tho-leg oi the at right angles to therdoor-frame, a vertically recip' rocating rod mounted adjacent the door, frame, a link having one end vpivoted to one right angular brace extending means connected to and actuated by the vertically movable rod for releasing the latch bolt of the door, means for opening the door connected to the upper end of thevertically movable rod, said means comprising a bell crank lever pivotally mountedupon the door-frame. and having one of itscnds con-1 nectedto the vertically movable rod, a link extending parallel to the upper edge of the door and having one end pivotally connected to the bell crank lever, thcother end of the said longitudinally entemhng lever-having an elongated-slot therein,- a second bell crank lever mounted adjacent the upper "edge of the door, one arm of the bell crank lever considerably shorter. than the other. arm, the short arm of the said bell crank lever having a lug slidably mounted Within the slot of the longitudinal lever, another link having one end pivotally connected to the longer arm of the last-mentioncdjbell crank lever and its'other end pivotally con nected to the top edge of the door at ap proximately the center thcreo.t, ,thc door unlatching mechanism operated in advance of the opening mechanism due to the play in the longitudinal slot'in the end oil the lever extending longitudinal and parallel to the top of the door.
