BENJAMIN MOSER, OF BROOKLYN, NEW YORK.
LOCK.
ClI-ZGIPI-CATION forming part of Letters Patent No. 313,098, dated March 3, 1885.
Application filed May 1, 1884.
To all whom, it may concern:
Be it known that I, BENJAMIN Mos'na, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Locks, of which the following is a specification.
The invention relates to improvements in locks; and its nature and advantages will be pointed out in the detailed description hereinafter presented, reference being had to the accompanying drawings. in which- Figure 1 is a plan view (lookinginto its interior) of a lock embodying the invention. Fig. 2 is a vertical section on the line 1 2 of Fig. 1. Fig. 3 is a vertical transverse section on the line 3 at of Fig. 2. Fig. i is a bottom iace view of the button WV. Fig. 5 is a view of the key, the dotted lines illustrating the relative position of the wings a. when spread apart.
In the drawings, A denotes the outer casing, within which are arranged the bolts B G, one being at each side of the casing, and the two being connected adjacent to their points by the cross-bar D, the horizontal center of which is removed, forming an elongated slot E.
The points of the bolts B G are adapted to move through slots or apertures formed in the end wall of the casing A, while the rear ends of said bolts, (lettered F G, respectively,) are of suitable form and length, and are each provided with a post, H, a lug, I, and a shoulder, B.
The posts H H serve as bearings for the ends of the spring J, which is secured at its central portion on the post K and exerts a forward tension on the bolts through the posts H II. The bolts B 0 are given their sliding movement, to permit or prevent the opening of the door by the arm K, which has a slot, L, in its end encircling the post H on the bolt 0, and'is actuated by the rotation of the knob-spindle. The bolts B 0, being connected by the bar D, have a simultaneous movement.
Adjacent to the inner edges of the bolts B (l are pivotally secured the oscillating levers M, the front ends of which have upon their inner edge the notches N, while the rear end of said levers M have posts 0 andlugs P, which (No model.)
latter are on the outer edges of thelevers, and arranged in convenient relation to engage the lugs I atthe proper time, as hereinafter described. The rear ends of the levers M are given a tension toward the adjacent portions of the bolts B C by means of the spring Q, the central portion of which is wrapped around the post K, while its ends bear against the posts 0, connected with the said levers M.
Between the front ends of the levers M is applied a bar, It, which is connected with a slide, S, located upon the outer face of the casing A by a pin, T, passing through the elongated slot V. The ends of the bar R are suitably conformed to enter the notches N, formed in the front ends of the levers M, at
the proper time, and to slide therefrom when the bar is moved forward by the operation of theslide S.
The bar R and slide S may be secured at the end of their forward movement,or be freed so as to move back and forth without obstruction, by means ofthe button 7, which is pivotally secured directlyin rear of the slide S, and has two flattened faces at different distances from its center, and either of which maybe thrown in contact with the end of the slide, whereby the extent of the movement of the bar R and slide S may be controlled at will. When the slide S is drawn to the extreme ofits forward movementflt carries the bar It with it and frees the oscillating levers M from any contact with the bolts B O, and said slide may be locked in this'forward position by turning the button V, so that its flattened face X most distant from its center will come behind the same.
WVhile the slide S, bar R, and levers M are in the position just described, the bolts B C may be moved freely by the knob-spindle alone, and the lock may then be employed as an ordinary latch. \Vhen, however, the buttonW' is turned so that its face nearest the center comes in contact with the end of the slide S, the ends of the bar Itwill enter the notches N, and permit the spring Q, to throw the rear ends of the levers M outward against the cor responding ends of the bolts B O, in which operation (the bolts being at their forward position) the lugs P on the levers M will pass behind the lugs I on the bolts B (land thus serve to lock the said bolts until, by the operation of the key from the outside of the door, as hereinafter described, the forward ends of the levers M are spread apart, so as to disengage the lugs I P, or until some one at the inside of the door moves the slide S, and thereby moves the bar R forward, which has the same effect as the key, so far as the movement of the levers M is concerned.
Upon the forward portions of the levers M are provided the correspondinglugs Z, which are arranged to be engaged by the two wings a of the key I), as hereinafter described.
Between the forward ends of the levers M, and immediately in rear of the bar R, are provided the standards 0, connected at their base by a cross-bar, d, the purpose of the standards being to receive the wards or combination of pieces c, said pieces being provided with notches f to rest over the cross-bar d. The
pieces 6' are provided, also, with notches g, which pass over the bar R, and the front ends of the said pieces terminate adjacent to the inner face of the cross-bar D, while their rear ends extend a suitable distance in rear of the standards 0, as shown. The pieces e are substantially the same, with theexception oftheir rear ends, which are cut to present when the pieces are in face-to-face contact an irregular upper surface, as shown in Fig. 3. The upper edges of the rear ends of the pieces 0 are of varied height, and a portion or all of same are beveled. The pieces 6 may vary in thickness, or be otherwise different from each other, so that when their relations are altered from that illustrated in the drawings a new key will be required to operate them. The set of pieces illustrated is but one of the many coinbinations or arrangements that may be devised, each necessitating alterations in the key for moving its parts.
In Fig. 7 I illustrate the key which is employed for operating the series or combination of pieces-e. It consists of the bladeb and pivoted levers or wings a, the inner edges of which parts a converge at a point adjacent to their pivots k, and have the inclined faces lettered Zm, respectively. Thelower ends of the wings or levers a project outward, as indicated, and are provided on their lower edges with wefts a, when desired. When the lower ends of the levers a are together, the upper ends of the samewill project beyond the side edges of the blade b, as indicated in Fig. 7, and when the upper ends of the levers a are moved toward each other the lower portions of same will spread apart, as indicated by dotted lines in Fig. 7. The lower edge of the blade of the key is provided with wcfts t, which pass over and engage the irregular surface formed upon the rear portion of the series or combination of pieces 6. It is plain that the wefts in the blade I) must perfectly fit said irregular surfaces, otherwise only a portion of the pieces 0 will be affected by the key. A key-hole guide or flattened sleeve, u, will be provided, in order that the key may be inserted from the outside of the door, for the purpose of reaching the combination 'of pieces e and spreading apart the levers M. The sleeve 21. will be of slightly greater width than that of the blade b, and when the key is to be insert ed therein the lower ends of the wings a will be moved toward each other, so as to enter the sleeve, and when said key has been sufficiently inserted for the upper edge of the sleeve to strike the outwardly-inclined upper portions of the wings a the lower ends of the said wings will be gradually forced outward from each other, and will come in contact with the projections or lugs Z on the levers M, and cause the forward ends of the said levers to move outward, whereby they will release the crossbar B and effect the disengagement of the lugs I P. The introduction of the key in the manner described also has the effect of engaging the irregular surface presented by the upper rear ends of the combination of pieces 0, and by pressing said rear portions the front ends thereof are elevated, so as to come directly opposite to the elongated slot E, formed in the crossbar D, connecting the two bolts.
When the elements of the lock are in the condition just described, it will be plain that the bolts may be moved into the casing A so as to unfasten the door by the rotation of the knob-spindle. In the normal condition of the series 0 their forward ends are depressed by means of suitable springs, to, against the casing A in rear of the lower edge of the crossbar D. When the rear ends of the pieces 6 are depressed, their front ends will be elevated so as to be in line with the slot E and permit the movement of the bolts B O, as aforesaid. It will be obvious, however, that the key must be suitably constructed to properly engage every one of the pieces 0, for otherwise some of said pieces would either remain in their normal condition, or their front ends would ascend too far, and. thus come in rear of the upper edge of the cross-bar D, while others would possibly come in line with the slot. Thus it will be seen that the lock under such a condition of affairs could not be opened.
Hereinbefore I have described the condition of the parts of the look when the same will operate as an ordinary latch, which is when the slide S is drawn and secured at the end of its forward stroke. XVhen the slide S is at the end of its back stroke, the lugs I P will be engaged and the front ends of the combination of pieces 0 will be in rear of the lower edge of the cross-bar D, whereby the boltsB C will be doubly locked, for it is plain that to unfasten the door the lugs I P must be thrown apart, and at the same time the front ends of the combination of pieces 6 sufficiently elevated to pass through the slot E. One ofthe series of pieces 6 has its lower rear edge resting upon the face of the casing A, so that when the key is inserted this piece being immovable, will arrest the key at the proper point to permit the slot E to move overthe front ends of the full IIO combination of pieces. When the slide S and bar R are moved forward, the combination of pieces 6 is elevated thereby, so as notto interfere with the proper movement of the bolts B C.
When the device hereinbefore described is used as a latch, the slide S need only be held forward until the lugs I B have passed each other and the combination of pieces 6 has en tered the slot E, which occurs immediately after the bolts B G havebeen started inward from the nosing A. Upon releasing the slide S (the bolts B 0 being on their back stroke) the spring Q, forces the lugs P on the levers M in front of the lugs I on the bolts B C and moves (owing to the inclined faces in the notches N) the slide S back to its former po sition. The effect of this operation is that the bolts can only return forward about one-half their stroke, being prevented from further movement by the lugs 1? coming in front of the lugs I. \Vhen the door to which the lock is applied is being closed, however, the protruding ends of the bolts B O strike the nosing A and are driven into the casing, and then when the door is finally closed the spring J has sufficient force to cause the lugs I to pass the lugs P, whereby the bolts B 0 look the door, and are themselves immediately deadlocked by the lugs B springing in rear of the lugs I. The lock is thus an automatic deadlocking latch.
It will be found very difficult to pick the lock described, for ifthe levers M are forced outward farther than the required distance, their front ends will pass behind the shoulders B and relock the boltsat this point. Thus even though the lugs I P become unlocked, the front ends of the levers and shoulders B will secure the bolts under the condition specified. The fact also that a portion of the combination of pieces 6 is beyond the sides of the keyhole will prevent any successful tampering with the lock.
To open the lock, the levers M must not only be properly spread apart, but it is also necessary that the combination of pieces 6 be successfully elevated. Thus one part of the lock acts as a check upon the other part until all parts are properly operated, which I consider impossible without the express key prepared by the manufacturer for the special lock to be opened.
The nosing A is of the usual construction, with the exception of the pins G on its edges and the elongated screw-holes D at its ends. The pins 0 when driven into the wood will hold the nosing in place until the lock may be tried or the screws applied, and the elongated screw-holes permit the nosing to be set nearer the look when the wood to which it has been secured has shrunk, and this without chang ing the hole made in the wood by the screw. The edges surrounding the elongated holes D will be flat, and a screw having a head whose under side is fiat will be used in securing the nosing in place.
I reserve the right to adapt the lock for use upon doors, boxes, trunks, 8m, and to modify the construction thereof within the scope of my invention.
