To lct'ZZ whom t 71mg/ concern:
Be it known that I, ALEXANDER CnAMoND, a citizen of the United States, residing at Lyons, in the county of Clinton and State of Iowa, have invented certain new and useful Improvements in Reversible Latches forRim- Locks, of which the following is a specification.
My invention relates to that class of locks ic in which the bevel of the latch may be reversed or changed to accommodate it to a door opening either to the right or to the left; and its objects are to provide a device and organization of this character wherein the construction is greatly simplified and the reversal of the latch readily and easily accomplished and without in any manner disturbing the internal mechanism of the case.
The invention consists in the construction, o combination, and arrangement of parts, all as fully hereinafter described, and pointed out in the claims.
In the accompanying drawings, forming a part of this specification, Figure l is an in- 2 5 terior View of a lock containing my improvements, the cap or top of the case being removed Fig. 2 is a sectional View on the line 2 2 of Fig. l. Fig. 3 is a detail view showing the latch-slide and latch-bolt in their relative 3o positions when assembled. Fig. et is a detail view similar to Fig. 3, but showing the latchbolt reversed on the latch-slide. Fig. 5 is a detail perspective view of the latch-slide, and Fig. 6 isa similar view of the latch-bolt. In carrying out my invention I employ a case composed of a shell A and a cap pieceA or top B of any desired description. The shell is provided with a suitable post a, which is internally threaded to provide a seat for 4o the screw that fastens the cap in position upon the shell. The post also provides a bearing for the springe', which operates the latch-slide in a manner hereinafter fully described.. Y i
TheletterCindicatesthelatch-slide,having a shank c, the head c', and a rear bifurcated portion or yoke c2, which receives the latch-operating mechanism. The shank and yoke of the slide are in the same plane, as shown in 5o Fig. 2, and thusform a smooth surfaceto slide` back and forth upon the under face of the lcase ordshell as the latch is shot or retract,- ed. T he metal of the case and cap is` drawn inwardly at a2 to form bearings for the barrel or arbor c/fwhich is provided with a square 5 5 `bore or channel to receive the shank or spindie of the knob in'the usual manner. The barrel or arbor is provided with two oppositely-projecting wings CL4, which constitute `the latch-operating mechanism cooperating 6o with the yoke of the slide, as hereinafter more fully described. The yoke c2 of the slide C straddles the inwardly-d rawn portion d2 of the shell. The ends of the yoke are bent at right angles to terminate in the upwardlyprojecting lugs c3, which are in the path of the wings al when the parts are assembled and coperate with the `wings when the barrel orarbor is turned in its bearings by the operation of the knob, whereby the slide is 7o operated to be retracted from the bolt-opening in the face-plate of the shell or case by the cam action of the wings upon the lugs. The forks of the yoke pass freely back and forth between the inner face of the case or shell and the wings c4, the yoke being therebyguided in its backward-arid-forward movements and 4retained at all times in proper position with respect to its associated parts. Theshank of the slide is provided with a lug 8o ci, preferably struck up from the body of the slide, to form a bearing for one end of the operating-spring c', which is placed around the post d, its other end bearing upon any suitable portion of the lock e or case. The slide is shot by the spring or is normally held in its forward position toward the bolt-opening in the end or face plate ofthe shell. The shank is also provided in front of the lug c1 with a pair of ears cibetween which the shank 9o of the latch-bolt rests, as more fullyhereinafterdescribed. The head c of the slide is slightly above the plane of the shank, the slide being slightly bent upwardly at the shoulder o for this purpose. tThe head of is somewhat greater in width than the shank of; the slide and forms with the shank a substantially T- shaped head. The head is provided with forwardly-projecting lugs c7, one at each end of its cross portion, which form a seat for the reroo ception of the head of the latch-bolt, as hereinafter fully set forth. The lugs c3, the ears SiO c5, and the shoulder c6 are formed by suitably shaping the metal of which the slide is composed, the lugs and ears being angular to the slide or projecting in planes at substantially right angles to the plane of the shank of the slide.
The latch-bolt D is composed of a suitable head d of the usual form and construction, having a bevel and a shank d', the shank being connected to the head at about its center, whereby a shouldei1 is formed by the body of the head upon either side of the shank. The shank is provided with two pairs of ears d2 d3, the former being located near the rear end of the shank and the latter slightly nearer the head, the distance between these pairs of ears being approximately the width of the ears c5 on the shank of the slide. The ears extend in pairs in opposite directions, as shown clearly in the drawings, and form a seat on each edge of the shank for the reception of the ears c5 of the shank of the latch-slide, whereby the slide and bolt are interlocked and the bolt may be readily reversed in either its right or left hand position and securely locked in place upon the slide in either of its positions. The ears cl2 d'of the shank of the bolt are angularly arranged with reference to the shank itself, projecting in planes at about right angles to the plane of the shank, the ears of one pair extending in one direction on one side of the shank and the ears of the other pair extending in the opposite direction upon the other side of the shank.
When the parts are in the position indicated in Fig. l of the drawings the shank of the latch-bolt is superimposed upon the shank ofthe slide, the ears c5 of the latter interlocking with the oppositely-projecting pairs of ears d2 d3 of the former. The ears d3 of the shank of the bolt in this position embrace the shank of the slide, while the ears c5 of the slide in turn embrace the shank of the bolt, thus holding the bolt and slide in alinement and compelling them to move simultaneously backward or forward, as if they were integral. The head d of the bolt rests in the seat formed between the lugs c7 of the head of the slide, as clearly shown in Fig. 3, thereby being held rigidly in position with relation to the slide. Vhen it is desired to reverse the latch, the cover or cap B of the case having been removed to expose the parts, as in Fig. 1, the latch-bolt is lifted from its position as shown in that ligure and is reversed or turned over and then reseated in place. In this reverse position the ears d2 of the bolt embrace the shank of the slide and the ears c5 of the slide embrace the shank of the bolt, these parts again being interlocked as before by reason of the position of the ears c5 betweenthe oppositely-extending pairs of ears of the shank of the bolt. The head of the bolt likewise rests in the. seat in the head of the slide, as clearly shown in Fig. e, and the parts are rigidly and firmly retained in their proper relations as before.
The head d of the bolt is of such thickness that in either of its positions its lower face is flush with the lower face of the slide C, the shouldered head of `the slide being of the proper height to form a rest for the shank of the bolt, as shown in Fig. 2.
The forward bevel edge of the head CZ projects normally through the opening in the edge or face plate of the case when in its forward position, and the relation of the parts is such that it is Withdrawn flush with the opening when retracted by turning the knob, but not entirely through the opening.
The barrel d3 is securely held in its bearings @2 in the shell and cap when these parts are assembled, being provided with slightlyreduced ends to rest within the bearings and projecting outwardly therethrough flush with the outer faces of the cap and shell.
The head d of the latch-bolt corresponds approximately in thickness with the inside width of the case and is thereby flush with the inner faces of the shell and cap-piece when they are assembled. The ears c5 of the latch-slide are approximately equal in height to the inside width of the case, and the ears d2 d3 of the latch-bolt together equal in height the same width, so that the parts when assembled are securely held against displacement between the inner faces of the shell and cap, as shown in Fig. 2, and the latch is re- .iained in substantially-horizontal alinement in either position and at all times. The tail of the latch-bolt preferably projects slightly over the lug c? of the slide in either of its positions, so as to come normally over the end of the vspring a and prevent its accidental displacement. The stop e is operated in the usual manner to permit or prevent the throw of the latch-slide. e
In a construction of this nature when the cover or cap of the case is removed the internal mechanism remains undisturbed while the latch-bolt is removed for reversal, the spring which rests upon the slide holding the parts securely in position. The latch-bolt and latch-slide interlock in either position of the former, which may be reversed by being turned over, the interlocking means being so arranged that the proper adjustment of the parts is secured and determined automatically and without any other change in the disposition of the bolt beyond its mere reversal. The slide and bolt are securely and effectively locked together in either position by the same means and constitute a strong and-rigid structure equal to an integral latch and slide, with the advantage of the additional function of providing a reversible latch.
It is obvious that changes and modifications of details may be made without in any manner departing from the spirit of my invention. For example, the form of the operating mechanism for the slide and of the parts of the slide coperatiug therewith may be changed by using anyotherequivalent means. Other changes may be made by those skilled in the art within the scope of my invention.
