l .Application IiJanuary 12,1904. serial-N0. 188,692. (Nomade.)

To all whom it may concern,.- V

Be it known that I, WILLIAM A. FAGAN, a subject of'Great Britain, residing in thecity and county of San Francisco, State of California, have invented certain new and useful Improvements inDoor-Releasers; and I do hereby.. declare the following to be a full, clear,`and exact description 'of the same.

`The present invention is designed foruse in connection' with flats or apartmenthhouses or houses wherein it is desired to release the lock-- catch of the front vdoor or outer door from aV distant point, thei object being to provide against the necessity of having to travel from a distant pointor to descendthe stairs for the purpose of releasing the outer door in order that the-same may b e opened' for a person'desiring admission, the invention residing in the meanswhereby thedoor-catch isjmechanically released and the door slightly-opened from a distant point through the mediumof a system of crank-levers and wire connections..`

To comprehend vtheJl invention, reference should be had tothe drawings, wherein-y `Figure 41` is an inside view'of a'n ordinary door, the ldoor-casing being partly broken away and sectioned in order to illustrate the location of the releasing device and the opener,

together with the connections for the opera. tion yofl said'devices. tional end' view of the casing, illustrating'the position of the releaser and the opener. Fig.`

8 is an enlarged broken. detail view of the door, the `casing lbeing in vertical section. Fig. 4 is an enlarged detail view ofthe releaser viewed from the opposite side from that disclosed by Fig.3 of the drawings, and'Fig. 5

the opening device for the door. The numeral 1 designates an ordinary ou'te door for ahouse, and 2 the casing therefor, to

which the door is hinged.

Within the side 2 of the casing is fulcrumed is an enlarged detail view in end elevation of the lever`3, which is connected to the 4ful-- accompanying.` sheet of.

Fig. 2 is a vertical sec spectively, tothe pillars 4' 6". The opposite arm of thecrank-lever 6 is'fconnectedby wire 8 to one Aend of the longitudinally-movable re- .leasing-bolt 7', which bolt works through the catch-opening of the lock-plate 8', fitted within the side' 'of the lcasing 2, Figs. 1,5 3, and 4 of the drawings'. Y The releasing-bolt 7' is held in place by means of the screw-stud 82, which studpasses through a slot 9 cutin the said bolt and screws into the lock-plate 8'. The Alockplate 8' is formed with an inclined shoulder 9',

upon which `bears and rides a roll 10, secured to one face of the slide-releasing bolt-7', Figs. 3 and 4 of the drawings. The louter or-- free end of the releasing-bolt 7', when the door 1 is closed, bears against the door-catch 10'. By this construction it is obvious that as the inner end of the vslide-bolt 7' is drawn upward the roll 10 working upon -the face-of the inclined shoulder 9 will force the said slide-bolt outward atan inclination. -As thusk moved the pressure of the releasing-bolt against the door-catch 10' will'forcethe catch outward beyond the catch-opening of the lock-plate 8' or back into the lclr, thus releasing the locked door and leaving same free to be opened by pulling upon the door-knob 11.' "So long as the upward or pulling strain continues on the wire 8 to maintain the releasing-bolt moved outward the door will be held releasedj It will be understood that the stud 82 acts as the fulcrum for the slide-releasing bolt 7'.

To. indicate that the door'is'rel'eased, an`

opener is provided which Will force outward the doora slight distance the moment the locke' catch has been released. lhis'deviceis operated mechanically by they movement of the releasing-boltwand is so constructed as to remove all` strain from thefloor when closed.'y The opening device is located within the side '3' of the door-casing, near the bottom thereof,

swings tranverse of the casing, the roll 14'` IOO carried thereby working within a transverse slot l15 cut in the face of the plate 13.y The projecting end of this roll when the crank-lever is inward its full distance fits within a socket or recess 15' cut in the rabbet 16 ofthe door-casing. Said roll rests against a bearingplate 16, secured to the edge of the door, so that the pressure of the roll upon the door during the opening thereof will not injure the surface of the woodwork.

The described device is actuated to open the door as the door-catch is released by the upward pulling strain exerted upon the wire 17, forming connection between the releasingbolt 7 and the bell-crank lever 12, acting to swing the crank -lever 12 outward transversely, causing the projecting roll 14', bearing against the edge of the door, to gradually force the door open a slight distance as the roll is thrown outward within the slot 15 of the plate 13. As the pulling strain which actuates to operate the releasing-bolt ceases the tension of the'spring 13 forces the crank-lever 12 inward or in a reverse direction, so as to restore the same to its normal or closed position. eXerts'a downward pull upon the wire 17 in order to draw the releasing-bolt 7 inward or restore it to its normal position. At the same time the tension of the spring 17', which forms a connection between the crank 6 and the doorcasing, Figs. 1 and 2 of the drawings, restores thelever 3 and cranks 4 and 6 and their connections to normal position. When the parts are thus restored to their normal positionrthe door 1 is free to be closed, which may be done automatically or otherwise. In the present case an ordinary pneumatic door-closer 18 is employed to close the door. However, the feature of closing the door forms n0 portion of the present invention. Hence no consideration need be given thereto.

The described mechanism for releasing the door-catch and opening the door is operated by means of the wire 18. One end of this wire is attached to the lever 3, Fig. 1 of the drawings, its opposite end terminating at whatever distant point from which itis desired to operate the releasing and opening mechanism. This wire 18 for the purpose of the present case shall be termed the main house-wire, meaning thereby the wire to be actuated from any fixed distant point within the house by the person desiring to operate the mechanism to release and open the door.

Having thus described the invention, what is claimed as new, and desired to be protected byLetters Patent, is-

1. The combination -with a door, of an inwardly-movable slide-'bolt for actuating the lock-catch thereof to release the door, devices for causing the slide-bolt to travel at aninclination to the lock-catch of the door, a transverselymovable device for partly opening the door so released, connection between the This movement of the crank-lever 12 releasing slide-bolt and the opening device by which the opener is positively actuated with the movement of the releasing slidebolt to release the lock-catch, and connections between the releasing slide-bolt and a distant point for operating the said slide-bolt and its connected device to release the door and open the same.

2. A door releasing and opening mechanism, the same comprising a longitudinally-movable releasingbolt for acting against the lockcatch of the door, devices for causing the rcleasing-bolt to travel at an inclination during longitudinal movement thereof to release the lock-catch, a transversely-movable device for opening the door when released, connection between the releasing-bolt and the opening device for the door so that the releaser and opener operate substantially simultaneously, a house-wire actuated from a distant point, connection between the house-wire and the releasing-bolt, and means for restoring the parts to their-normal position when the housewire is released.

3. Adoor releasing and opening mechanism, the same consisting of a longitudinally -movable releasing-bolt, devices for causing the same to travel at an inclination during the longitudinal movement thereof, a house-wire operated from a distant point, connection between the said wire and the releasing-bolt, and means for restoring the parts to their normal position when the house-wire is released.

4. In a releaser for doors, the combination with the door-casing, a lock-catch plate fitted therein, a releasing-bolt slidably connected to said plate, a roll carried by the bolt, an ineline surface on the plate upon which the roll of the bolt works to move the same outward, a house-wire, connections between said wire and the releasing-bolt, and means for restoring the parts to their normal position when the housewire is released.

5. In a releaser and opener for doors` the combination with the door casing, a lockcatch plate iitted therein, a releasing-bolt slidably connected to said plate, a roll carried by the bolt, an inclined surface on the plate upon which the roll of the bolt works to move the same outward, a transverse]y-movable device for opening the door when its lock-catch is released, said device bearing against the door when closed, connection between the opening device and the releasing-bolt, a house-wire, connections between the house-wire and the releasing-bolt,V and means for restoring the parts to their normal position when the housewire is released'.

In witness whereof I have hereunto set my hand.
