PANIC-BOLT.

Specification of Letters Patent.

Patented aprn 20, 1'909.

T 0 all whom it may concern:

Be it known that I, HENRY G. VOIGHT, a citizen of the United States, residing at New Britain, county of Hartford, State of- Connecticut,-have invented certain new-and useful 1m rovements in Panic-Bolts, of which the in owing is a full, clear, and exact de- My invention relates to locks and particularly to the so-called panic bolt constructron. r

The object of my invention is to rovide simple and efiective mechanism em racing certain features whereby many advantages are gained.

i In the drawings, Figure 1 is a fragmentary perspective view of a portion of a door illustrating my improved look as it appears when applied thereto. Fig. 2 is a section of the door showing the appearance of the look at 'gppositesides of said door. Fig. 3 isa view the inner side of the case showing the interior mechanism. Fig. 4 is a section on the plane of the line :t-e, Fig. 3, looking in the direction of the arrow. Fig. 5 is a detail view partly in section. I l

1 represents a door; 2 a lock case;

5 is an operating bar extending across the face of the door and arrangedto moveto and from the door, said bar being so connected that bolts 3-3 will be withdrawn when said bar is moved in either direction, that is, to ward or from the door.

- 6 is an outside bolt-o erating device in the.

form of an ordinary nob with .the usual mounting.

7 re resents the end of a cylinder look accessi is at the outside and for dead-locking the mechanism against operation by the knob 6, said dead-lockin mechanism being suchgthat, when locked, the bolts 3-3 may still be operated by the bar 5.

The bar 5 is carried at one end by a lever 8 mounted on pivot 9 in bracket 1. The other end of the rod 5 is carried by a link 8*. mounted on bracket 4 carried by the door, so that the bar 5 will stand across-the'face of the door, as best seen in Fig. 1.

The bolts 3-'3 may be provided with suitable guides or bearing, boxes 3 3 the latter being secured to the door near the top and bottom. In Fig. 5, the locking end of one of the bolts 3 is shown, and it will be I seen that contained within the housing or bearin 3 is a spring 10 which is so connectedthe with

same. ably provided for the lower bolt.

11 is a central pivot.

12. is a'walking beam pivoted thereon.

bolt 3 as to normally project the The same sort of a spring is prefer 1314 are links connecting opposite ends 2 of the walking beam 12 with theopposite bolts 3 -3 respectively, as by a toggle arrangement, said toggles being ofi center at all times and normally standing-as shown'in solid lines Fig. 3.

is a slide mounted in the lock case 2' and operatively connected as by in 16 with one end of the walking beam. he pin 16 may be carried by the end of the hnk 13 and passes through a radial-slot in the walking beam 12 and into a longitudinal-slot in'th slide 15. If theslide 15 is moved-upwardly from the position. shown insolid lines 3) to the position shown in dotted. lines, 1t 1 moves the pin 16 and all parts connected therewith. This movement is in a, direction to withdraw the bolts 83*;

17 is a pin carried by the link 14, which pin passes through a radial slot in the opposite end of the walkin beam 12'and also stands in a recess in a sli in yoke 18. This yoke is provided with suitab e guides in case 2.

19 is a roll back connected to and con-' trolled by the outside knob 6 in the usual manner, said roll back 1-9 engaging the tail of the sliding oke 18. in such manner as to permit said slide .to be drawn back by the operation of the knob 6. This movement of the sliding oke .18 through its connection with the we king beam 12 causes the retraetionoftheibolts 33. A

20 is a locking shoulder on the hub or roll rack 19, which is arranged to be engaged by the dead-lockin slide 21 mounted in the case 2 and arran ed o be shifted by a key inserted in thecylinder lock 7.

22 is a tumbler carried by the slide 21.

23 is a roll back arm mounted on a roll back 24, which, when the parts are assembled, is in operative engagement with the outside lock 7.

As shown in Fi 3, the roll back 19 is free however, the operator posite sides of a door; for independently re x;

the same means, the slide 21 is advanced to engage the locking nose 20 on roll back 19. Under these. conditions, of course, the outer knob can not be turned and hence access from the outside is prevented save by the use first of a proper key. i'hislocking ofthe roll back hub 19 does not, however, affect the operation of the bolts 33 by the bar 5, which may still be retracted should the walking beam 12 be operated.

Now, referring to Fig. 4, it will be seen that the slide 15 has a suitable bearing such as an anti-friction roller 25 at its fora ard side.

26 is a lever pivotally' mounted in the bracket 4, one end of said lever projecting under the roll 25. The lever portion 8 of the inside operating mechanism is provided tiith two horns S 8 which stand above and below the lever 26 and at opposite ends thereof. By reason of this arrangement, a movement of the operating bar 5 in either direction will tilt lever 26 so as to force the slide 15 upwardly, which movement, as be- I to retract the ho ts 3-3.

I By having the pin 16 stand in a longitudinal slot in the slide 15, the a alking beam may string on its axis .11 without moving the slide 15, thus permitting said walking beamto be operated by the shding yoke 18.

27 is a spring, operating to normally hold the slide 15 retracted in the position shown in solid lines Fig. 3.

What I claim is:

1. In a panic bolt, a bolt member, means for normally projecting the same, two separate operating means for arrangement on ope tracting said bolt, one means arranged to move toward or from the door for its operative movements and arranged on the inner side of the door, with connections between the last mentioned means and said bolt whereby either movement will cause the retraction of the bolt.

2. In a panic bolt, a bolt member, meansfor normally projecting the same, two separate operating means for arrangement on opposite sides of a door; for independently retracting said bolt, one means arranged to move toward or from the door for its operative movements and arranged on. the inner side of the door, with connections between the last mentioned means and said bolt whereby either movement will cause the rctraction of the bolt, and means for deadlocking the other bolt operating means witl1- out interfering with the operation of the other bolt-operating means.

3. In a panic bolt, a pair of op ositely ar ranged bolts, means for norms y causing said belts to remain projected, means for retracting said bolts comprising a Walking beam, links connecting the same with both of said bolts, an operating device connected with said walking be am and comprising a bar arranged transversely of the door, and means intermediate saidbar and said walking beam whereby movement of said bar toward or from the door moves said beam in a 7 0 direction to retract said bolts. 4. In a panic bolt, a pair of oppositely arranged bolts, means for normally causing said bolts to remain projected, means for re I tractin'g said bolts comprising a walking beam, links connecting the same with both of said bolt'sQan operating device connected with said walking beam and comprising a bar arranged transversely of the door, and means intermediate. said bar and said walk-.80 ing beam whereby movement of said bar toward or from the door moves said beam in a direction to retract said bolts, and including a reciprocatin slide, arranged adjacent to one endof the am. Y 5. In a panic belt, a pair of oppositely arranged bolts, means for normally causing. said bolts to remain projected, means for re tracting said bolts comprising a walking beam, links connecting the same with both of said boltsjan operating device connected with said walking beam and comprising abar arranged transversely of the door, means intermediate said bar and said Walking beam whereby movement of said bar toward or from the door moves said beam in a direction to retract said bolts, a second means for operating said bolts comprising a knob operatively connected with said beam, and means whereby said beam and operative connection .100

may move independently of the knob.

6. In a panic bolt, a pair of oppositelyarranged bolts, means for normally causing said bolts to remain projected, means for retracting said bolts comprising a walking beam, links connecting the same with both of said bolts, an operating device connected with said walking beam and comprising a bar arranged transversely of the door, means intermediate said bar and said walking beam whereby movement of said bar toward or from the door moves saidbeam in adirectiom to retract said bolts, a second means for operating said bolts comprising a knob operatively connected with said beam, means whereby said beam and operative connection may move inde endently of the knob, and means for deadocking said knob.
