This invention relates to bolts, commonly known as panic bolts, as employed for emergency eXitdoors and for similar purposes, and of the type in `which the release of the bolts is automatically effected by the pressurer of a crowd towards the door which ordiv The obj ectl 0I the innarily bars its passage. vention is to facilitateV the production of the said bolts whilst ensuring the ethcacy of the same. Y
The invention comprises the employment in combination with a pair of bolts or sliding bars adapted to be moved in opposite directions, of an actuating member which operates with a sliding movement and engages the said bolts or bars through the medium of projections and inclined slots.
same are not right and left handed, but the same bolt or the same form of bolt can be used 0n either side of the one actuating member. In the accompanying` sheet eli' explanatory drawings Figure l isa sectional sideelevation, and Figure 2 a plan of an emergency door bolt constructed in accordance with this invention, the bolts being shown in the withdrawn position. f j f Figures 3, 4 and 5 are perspective views illustrating the interengaging portions of the two bolts and the actuating member. Y
In the construction of a panic bolt as shown, for use with an emergency exit door, the device comprises as is usual a pair ot sliding bars, bolts or shoots a, of which one secures the unper and the other the lower end of the door. The adjacent ends of the'said bolts are preferably cranked or cut away for the admission between them of the inner end of the push piece or bolt actuating member the Vouter end of which is connected in any ordinary manner with the usual bar or railc extending across the inner side of the door to receive the pressure resulting in the release oI' the bolt Jfor the use of the emergencyor panic exit.
On the inner face of each of they said cranked portions of the bolts there is provid` ed an oblique projection Z extending in anY inclined direction 'across the bolt. Y The cranked ends of both bolts are precisely similar, there being no right and left handed dispositions of the projections When a pairv Also the invention comprises the constructionr of. the vparts so that the said bolts or the engaging ends of the*V I claim as new and desire gage oppositely inclined slots el on such member, so that a sliding movement of the -a'ctul Vating member in a vdirection at right angles tothe plane -of the door produces opposite longitudinal movements ofthe bolts.
" The adjacent ends of thebolts and actuating member are carried by Va suitably shaped andclosely fitting body part 7 adapted to be ksecured to the inside face of the door.`
Y Tofenable the actuating members'to be operated by a watchman or other authorized' person Jfrom the outside of the" door, the end of theactuating member ZJ opposite the bar c may be adapted in any convenientl manner for operation by a suitable key or like appliance inserted through an aperture in the front ot .the door. Obviously the mode of engaging the key and actuating members may be et i'ected in a variety oi ways. For example, a
screw threadjconnection, or` a bayonet joint connection may be used. In the construction f shown theforward end g of the part b is screw-threaded. To this end'canbe detachablyv connected an internally screw-threaded tool t (Figure 5) by which a pull or push can be'imparted'to Z9 from the outer side of the door. i
I-Iavingn thus described my invention whatv Patent is`:- c Y l. In emergency door bolts, the combination comprising a slidable actuating member 'formed on a pairof opposite sides with oppositely inclined slots, a pair otsimilarly to secure by 'Letters form-ed slidablebolt members movable in op posite directions atright angles to the. ac-v 1 tuating member, an oblique integral projection on each bolt member'adapted to engage one of the inclined slots of the actuating substantially as described;
2. In emergency door bolts as claimed in claim l, the combination with the actuating member of means whereby the said niember Y may also be actuated by detachable means from the outside of the door, substantially as described.
In testimony whereof IV have name to this specification. CHARLES YEOMANS HOPKINS.
