Description

tnitrd giant NQPETRE, or NEW-Yonah. Y.'
Letters Patent No.v 95,507, dated October 5, 1869.
IMPROVEMENT IN coMBINED LATCH A ND LOCK. f
The Schedule referred to in these Letters Patent and making part of the salue.
To all whom it may concern.:
Be it known that I, N. PETR, 'of the city, county, and State of New York, have invented certain new and useful Improvements in Locks; and Ido hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specifica'- tion, in Which- Figiue l represents a plan of the interior of the lock, as it appears when the bolt is connected to and can be worked by the door-knob or its co-operative parts.'
Figure 2 represents a' similar plan, as it appears when the bolt is disconnected from the knob or-its co-operative parts,'and cannot bemoved thereby.
Figure 3 represents a section through the lock, at the red line y y ofiig. 1.
Figure 4 represents a section through the lock, taken at the red line x a; of iig. l.
Figure 5 represents a perspective view of the bolt and lits tail-piece removed from the look, and turned over, so as to show its under part.
Figure 6 represents the key of the lock, in perspective.
Similar letters of reference, where they occur 'in the separate iigures, denote like parts of the lock in all of the drawings'.
This invention relates to that class of locks which I have denominated latch-looks, or locks wherein, by means of a ky and hub-eccentric, a bolt is so operated as to be put into connection with the ordinary door-knob, or thrown out of connection with said knob, as to make it a lock or a latch, as may be desired, the same bolt acting for either.
And my invention consists, first, in so combining the bolt and knob-levers as that the raising of the bolt-lever by the eccentric or its equivalent, actuated from the exterior by a key, shall move the knob-lever out ofthe way of the cam or tappet-arms on the hub Y through which the shank of the knob passes, anda reversed movement of said bolt-lever allow it to'come into ation with said tappets again.
An myginvention further consists in the construction of the stop against which the bolt-lever is thrown when moved by the eccentric, and the opening in the said lever, so that as said lever,is moved up against said stop, it will project the bolt further out of the lock.
To enable others skilled in the art to make and use myinvention, I will proceed to'descrbe the same with reference to the drawings.
The lock `herein represented is a mortise-lock,-but the same devices may be applied in Wholeor in part to other locks, and I do not, therefore, restrict my invention to mortise-locks.
The lock-case A and the face-plate B maybe made' l), a boltelever, D, which extends tar enoughv into the lock-case to act and be acted upon, as will beexplained.
The central portion of the bolt-lever D is cut away, so that, as shown in iig. 1, it may move on, and be guided by the stop E, which is secured to the lockcase, and a cani-slot, l, is. formed' in said cut-away or open part, so that as the/bolt-lever is raised up, as shown in rig. 2, and the cani-slot comes z gainst the slot E, the bolt will be projected further out of thc lock-case than itis in its connected condition or posif tion with the knob-lever G, as seen in iig. l.
On the under side of the bolt-lever there isa projection, e, that takes into the notch Il ot the'eccentrir.- H, when said-notches come opposite to said projection; but neither the projection or depressions, no1' indeed the eccentric, are absolutely necessary; for any other means of raising up and' letting down said boltlever by means of the key (such as tumblers, wedges, or levers) will accomplish the` saine generalfpurpose as the eccentric does, and 1', therefore, mention it as the instrument for n'ioving the lock-lever, but do not limit my invention'to its use especially.
The bolt-lever has, upon its rear portion, ahook, e, which takes over a pin, f, in thc knob-lever Gr, when the .two levers are allowed to come together, and which unites them for joint act-ion until again separated.
And belowisaid hook, and' on the under side of the boltflever, as better seen at g, in its turned-over posi tion, Vin fig. 5, there is a recess and plane, which takes in the lower end of the knob-lever G, and operates it, as will be hereafter explained.
Underneath the eccentric H there is a plate-spring, h, which has a projection, yi, upon it, which takes into vthe notches d in said eccentric, when theycome' opposite to it, and this spring may thus hold the eccentric in either of its positions by frictional pressure, whichis easilyovercome by the key when the eccentric is to be turned.
The knob-lever G, as I term it, is pivoted to the case at j, and a spring, k, behind it, tends `constantly to press said lever toward the bolt-lever D.
The hub I, through which the shank containing the knob or knobs J passes, has upon it three arms` or tappets l. lA portiou'of the perimeter of each ot" these tapets is rounding, as at on, so as to work lagainst or in the rounded depression n, in the knob- The bolt-lever D is pivoted to therbolt c at the'4 point b, the pivot being in the form of a screw, and openings Vq q are made in the sides of the lockcase, opposite to said screw, so that 1t may be taken out, the bolt turned over, and the screw or pivot replaced, without opening up the lock to reverse the bolt.
The bolt c is kept in a position for smoothly moving between its guides a a, by a spring, lr, while the boltlever D can be moved out of the plane of the movement ofthe bolt, and both bolt and lever are moved out of the case, to an extent, by the spring s.
The lower portion of the knob-lever G is made thin and wedge-formed, so as to freely move under and into the recess g of tbe bolt-lever, when the two levers are allowed to connect with each other.
WVhen the bolt-leveriD is moved up by the ,eccent-ric, or other means employed therefor, its ledge or plane g, moving against the rounded and lower end of the knob-lever G, forces back'said knob-lever, throwing it out of connection with the bolt-lever, as shown in iig. 2, and when the bolt-lever is 'let' down, the spring k, reacting, moves the knob-lever toward the bolt-lever, and the hook'e and pin f connect, and the i case, defines the proper working-position of the key in the eccentric. o Having thus fully described my invention,
What I claim therein as new, and desire to secure by Letters Patent, is i l. The combination of the bolt and knob-levers, with a raising-mechanism, operated by a key from the exterior of the lock, so that the raising of the boltlever shall disconnect it from the knob-lever, andv .move the latter out of the reach of the tappets on the hub that the knob-shank passes through, substantially as and for the purpose described. o
2. The combination ofthe stop E with the open or slotted bolt-lever, and the cam-opening Flleading l therefrom, so that `the raising up of the bolt-lever shall project the bolt further from the lock-case than itis when simply actingas a latch, substantially as described. o
