Doon-Lock.
Specification forming' part of Letters Patent No. 2,4886, dated December 17, 1842; Reissued May '13,
185i, No. 201.
T0 all whom z' may concern: Y t
Be it known that I, JOHN P. SHERwooD,
of vSandy Hill, Washington county, and State of New York, have contrived and in-V vented some new and useful Improvements Not Known or Used Before, in the Construction Vand Manufacturing of Doori Locks, vand the` following is an exact and and covered bythe two face plates; the aperture for the bolt in: the .front end of said lock is :as wide as said end, i so that VVthe molder may dispense. with setting a core; anda stay marked S (withtwo screw holes through it) from.' c; to .171- inch wide and .from l?? to 3 inches'lon'g, risesionthe lower front corner of each face protectingthe bolt hole. This improvement facilitates and cheapens the casting of a. case,xby lowering the sides andV ends and doing away with the setting of a core. .It also fits` every outside case for either a right or left hand door, without turning the lock upside down; andz it renders the lock stronger and more -durable A glance at the drawing, shows its peculiarities and their use. The inside of the caseis' cast with common fixtures, such as friction plates, studs and braces to keep the bolt and other detached pieces in their respect-ive places. My second improvement is in making the bolt with notches, one on its lower, and one exactly similar, on its upper edge, so that in connection with the vibrating or co-nnect-ing bar A a horizontal motion is given to the bolt and also adapts it,A by simple reversion to a right or left-hand door. Each is out perpendicularly and extends through one third part of the"bolt,reducing the bolt, in the center, between the two notches, to one third of its original size.
F ig. l, shows the bolt, with its two similar and opposite notches, a, a; its back end, b, forked, so that it may pass a screw; and its front end, c, beveled to make one bolt answer for both lock and latch.
F ig. 2, exhibits the vibrating or connecting bar A, for moving the bolt which is of very irregular shape, and nearly fills the upper half of the case. Its lower front corner d, projecting downward is made to fit the notch a., in the top of the bolt for the purposeA of moving or fastening the bolt at pleasure. At its upper front corner, e. shows a small holefor a screwon which it vibrates, and near by f, shows a. large one .for-.the handle.
for one sliding car or` impelling weight, and :on the other side for twol sliding cars hereinafter described. On each side1of this bar, larethree studs, g, z., i, in height equal Vto the `original thickness of the bar, and` axcurved key-guard, 7c, not quite as highias thestuds which shield thelocking car. Stud g is at the .lowerback corner.; rnear the center,
and z' aboverand back ofv i.. Each stud fonl one side has a correspondingstud, similar .and similarly situate o n the opposite side: /i, ande, forman inclined track or way,z'
vbeing placed obliquely above @toward Vthe,
1 80 i ing studs n theopposite side of the Jbar front end of the case, and .as the correspond- `form a similar track or way we have `a Nearly all of the back endl ,of this bar is made quite thin, as at A2 leave.` ing space between it and the case, on one side=V double inclined track or way for the safety' y lcars. hereinafterdescribed)-` to pass up and down. .A little above thecorner studl g,.a lnotch, Z, opensfrom the backend of the bar,
toward a pointgbelowthegcenter' stud L,1a
isa
These studs add power to'this car and con- Y nect it with safety cars G G2, hereinafter described, in a way that holds the three cars fast together when locked. The large notch fn., gives room for the double-aotion-locking car B passing stud 71, of the connecting bar A. The sides of this notch n are in one part horizont-al and in another oblique or inclined. In onepart of its 'movement on the studslJ and g of said connecting bar it is horizontal, and, in another, inclined. rIhe studs L and g of the vibrating or connecting bar A, thus become at diiferentperiods, a horizontal and an inclined, track or way for the locking car B to move upon. The small notch 0 admits the key Fig. 5 by which the car is moved. An acute angular projection, p, near stud m, catches under a stud D on the side of the case E when locked as seen in Fig. 8 and fastens the car. The locking is effected by a compound and backward movement of this car B which is new and peculiar to my lock. Another car, eX- actly like this with similar action, may be attached to the other side of the connecting bar, if greater security be desired.
G Figs. 4 and 7 shows the shape of the two safety cars, which are exactly alike, excepting one (G2 Fig. 7) is twice as thick as the other, and the thicker one has a groove H over the key-guard, c, of the connecting bar A. A notch, g, in each of these cars G G2 receives one of the studs fm, of the locking car, when unlocked as seen in F ig. 6 and r is along opening for the studs L and t', of the connecting bar. In size one of these cars G is nearly twice as large as the locking-car B. One is on each side of the connecting bar A. The double-action locking car lays in a cavity of the connecting bar and under the thinnest safety car G2. The safety cars always move on the double inclined track or way, before described, and in a direction opposite to that of the locking car. They add strength and stability to the lockingcar, and prevent the locks being picked.
In the process of locking, the key is turned back, instead of forward as in other locks; the safetycars rise simultaneously to their utmost height; the double-action locking-car then moves horizontally, a sho-rt distance, after which it descends toward the back end of the case upon its inclined track OI' way formed by studs 7L, and g, the safety cars at the same moment descending toward the front end of the case, on the double nclined track or way formed by studs L and z',
before described, until each reaches its lowest point, and then all three' combine in firmly holding both the vibrating or connecting-bar, Vand bolt fast, as representedV in F 8 which shows the bolt as locked-the projection p being locked under stud D and the safety car G having dropped down behind stud m which locks the whole together. To unlock the bolt the safety cars be first raised. v
Fig. 5, represents the foi-.m of the 'ke ln locking, the aperture c', lvfof vthe key passesaround the guard 7c, of the connecting-bar A and the bit u, raises the safety l G must Y car. G? while at vthe same time the bit` t, l
entering the notch o, yof the double-.acting locking car B strikes the back side off-the Y Y 'L v notch and moves the locking car B at irst horizontally and then in a descending-back-` ward oblique, or inclined direction, until the projection y) of thecar becomesfast under and against stud D and holds the connecting-bar A and bolts c stationary. In unlocking,` a reverse movement is necessary-first raising the safety cars as before stated.
That I claim as my invention and .for which I desire to secure an `exclusive right by Let-ters Patent, is this: viz.
I claim the peculiarV construction and double action (upon an inclined and horizontal track or way) of the locking car'B as hereinbefore described; and the combination of the locking car B. and safety carsG G2, with oneianother and with the connecting or vibrating bar and bolt Aas within described,.- i' so as'to fasten the bolt C securelyandrpre- Y j i vent its being picked.
