Spieri'licationorniing part of Letters :Patent Nef 213.051.. date-d ,Mn rch l1, llgrapplication filed February To all rwhom -it may concer-n 4 Be it known that I, Gnnsrnic H. POND, of- New York, in they county of N ew York and State of New York, have invented certain newand useful 'Improvements in Locks; and I do hereby declare that the'following,` is'afull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make andiise the same, reference being had to the accompanying drawings,
and to letters of reference 'marked thereon,
which forni a part of this specification- Figure l being` a plan view of my improved lock with the inside plate removed and showin g the wires for the conduction o f the electric current, the a-rrangcnient ofthe springs which are employed for closing and breaking the current he slidinnr holt with the non-conductine 'ein its end ,tli'c "tuinblcrs which are pivoted thereto, the springs for holding them. in position, the dog` which holds the bolt in its unlocked position, and the position of the keys used with the lock, the parts in the figure bein g shown in the positions they assunicwhen the door or other device upon which they are placed locked. Fig. 2 is also a plan view showing the parts above alluded to in the posi tions which they assume when unlocked. ldipgu is a transverse section showing the p0; sirion ot' the keys with reference to the lock. Fig. 4 is a perspective view'of'the sliding or locking bolt and the forni which is given there to; and Fig. is an elevation of one of the.' tunihlers and a portion ot its spriuv. Similar letters denote like part-s in all of the iigure's.
'lhis invention relates to locks for various purposes where itis desirable to have a current ot' electricity pass through them at times, and where it is necessary to break or discontinue said current at other times.; and it consists in constructing' ,such a. lock in such a manner that when the locking-bolt is thrown outward, or into a position to. lock the door or other device to which it may be applied, the current of electricity will flow through .it unbroken, but so that when lthe'locking-bolt is thrown inward, or into a position to unlock the door, the current will be breken and re' niain. thus until. the locking -bolt is again .thrown into a posit-ion to lock.
,Theriuvcntion further consists in certain combinations and arrangements of some ot" the parts of which the lock is composed, which features render it applicable to various purposes, such as securing the doors of safes,
inoney-drawers, lire-alarm sinal-boi;es,A and,
inshort, to any device in which it is desirable to have a current of electricity pass, and where it is desirable to slierten the circuit, econoniize the force .required to keep up the longer circuit, or give notice that the lockhas been tampered with.. v
In constructing this'type of locks I use any suitable sized plate A, 0f the usual or any required material, it having upon one of its surfaces flanges A, which serve to inclose the operatingparts of the lock. To the edges of thcseiiangfni or to some proieotions from the plate Aanother plate, 2x2, is secured, the lastnained plate completing; the inclosnre of the mechanism operated by the keys, and also of the circuitfbreaker.
To the plate A or to the anges Al there are secured, by screws or otherwise, blocks of any material which is a nonconductor of Ielectricity, and to these metal springs B B are sccured in such a manner that their outer or free ends shall come in contact, or nearly so, when they are in their normal position, or when not ,separated by the sliding bolt hereinafter to' be described. These springs sustain such a relation to the sliding or locking holt that when said bolt is'in its locked position, as
- shown in Fig. 1 of the dra-wings, their outer ends will be allowed to come in. contact and thus permit the'currcnt of electricity to ilow throughithe structure, it being brought thereto and taken therefrom by means of conductingwil'esl) and D, but so that when the lockingbolt is thrown back into its unlocking position, as shown in Fig. 2, it shall separate their outer or `ifree ends to such an extent as to make a break inthe' current, and thus for the time being prevent any flow of electricity through the structure.
The wires above alluded to may be connected to any line'leading from a battery used for other purposes, or they may be connected witl` a local battery expressly for operating the lock. 4 f
The sliding or locking;` bolt C, above alluded v to, is shown in Figs'. l, 2, and 4, and consists of abar of mehl, the outer end of which is of snicientthicknessand width to give it .the required strength, that portion thereof which is within the lplates of the lock being rcdncedin thickness, as shown in Fig'. Il, in order that the tunlilers which serve to retain it in position niaf'ff'be pi'voted thereto, for
'fusedthroughl the material of which the lock is made'.- Ata suitable point betweenthe vtwo ends of non, o .themas .farmed in resi-under 4 {sur-face a'peculiarlfy-for1ned recess, C, as shownin Fig. 4,- the object, being?" to provide 'f'a'spaeeginto which' a `nih formed on the key j fshallgenten and thusasfthdl'key is turned, p force the holt-outwardf 0111,54 iward, as occasion y may require. Thisbol't `isalso provided with 'a slot, C, the length of `which isfsuicient to A kpermit the bolt-to movethe required`distancc.-
[It also has formed inits upper edge a'reeess,

" J The tumblers referred t are lettered Eva'nd` 1 1E?, and consist of plates of metahfwhich are pivoted to the looking-bolt C, and move hori zontallywithit. vNear their free ends thesev `tuinblers are provided with a slot, E?, vwhich .corresponds with-C4 in bolt C, ex`cept .that
from its upper surface there is projecting downward a pin or portion of the plate let tered E4, the purpose of which. is to engage with a stud, A3, which is fast upon the inner surface of plate A of the lock, and thus prevent the retraction of the boltlC without the use of the key. These tumblers are forced downward at their free ends, so as to cause 'them to engage with the stud Afby means of springsl? F, which are attached to them, and
hear-against the projection on holt G, -as
For aiding? in the outward or locking movement of bolt G, a spring, G, is attached to the plate A, one end of which bears against the projection of said bolt, which causes itto be pressed' upon` as said bolt is retracted, and
consequently to aid in throwing the bolt ontward.
BEST AVAlLABLE COW To provide for holding the holt in its nnloeked position, and. to prevent it from or-ing moved from that position by the key which. unlocks it until such time as a second hey is brought into requisition, there is placed hy vthe side -oi the locking-bolt a trap-tumbler, lai, which is pivotcd toA the loch-plate in such a manner ,that its free end may 'ne 'raised n3-1a key, 'it being forced downward hyrincans of a spring, H'. Upon the under surface of tumbler there is formed a projection, which,
when the loehingjbolt C and the tumble-rs E 'and E1 are thrown backward, or into theposi tion in which they are placed when the door is unlocked, falls into a notch, E, formed in their-upper edges, and thus holds the holt in its unlocked position, and renders it impossible to force the bolt G forward untilthe key I is inserted and the trap-tumbler lifted out of the notch E3. f
,It-Will be seen that Athis arrangement. oi' parts renders it impossible for' any one person -tounloek and again loelr any-dooraor device to-which this lock' is attached, unlessin possession of hoththehej's. o Havingjthus described 'my inventionpwhar claim, and desire to secure by Letters 'Patr-.nn l l1s- 1. In'fcoxnbination with a lool; for various purposes, electrical connections, substantiallji -as described, and a flook'ng-holt-having upon. one of its ends a non-conducting substance.

The trap-tumbler H, when constructed and arranged substantially as and for the purpose setforth.
3. The combination of the locking-ooit (f), tumblers E El, trap-tumbler H, and stud A, theparts beingarranged to opera-"eeI substantially as and for the purpose set forth.
