3,026,137 Patented Mar. 20, 1962 3,026,137 7 LATCH BOLT CASING ANCHOR Fred J. Russell, 3800 Don Felipe Drive, Los Angeles, Calif. Filed Dec. 9, 1958, Ser. No. 779,134 8 Claims. (Cl. 292-337) The invention relates to locks and latches and has particular reference to latch bolts frequently identified as tubular type latch assemblies wherein there is provided a housing for the latch bolt mechanism separate and apart from the remaining portion of the lock which is interconnected with the lock upon installation of the several parts in a door.
This is a continuation-in-part of co-pending application Serial No. 707,931, filed January 9, 1958, now abandoned.
One of the problems which regularly confronts installers of typical cylinder lock sets is the necessity for having to provide a non-circular latch face and for having to attach the latch face to the door edge with wood screws.
It is accordingly among the objects of the invention to permit mortising for the face of the latch bolt casing by use of a step drill.
Another object of the invention is to provide a new and improved anchor for a latch bolt casing which resiliently "braces between the latch bolt casing and the edge of the side hole in the door itself, thereby fastening the latch bolt casing to the door in a firm and dependable fashion in advance of mounting the operating mechanism in place.
Still another object of the invention is to provide a new and improved latch bolt casing anchor which mounts the latch bolt casing independently in the door quickly and easily without need to secure the latch bolt casing face to the door edge by means of wood screws or other means.
Still another object of the invention is to provide a new and improved anchor mechanism for latch bolt casings which is sulficien-tly simple in its operation to permit acceptable installations to be made without special skill being involved.
Still further among the objects of the invention is to provide a new and improved latch bolt casing anchor which is sufiiciently resilient to compensate for variations in side hole locations in the door.
With these and other objects in view, the invention consists in the method of operation and the construction, arrangement and combination of the various parts of the device whereby the objects contemplated are attained, as hereinafter set forth, pointed out in the appended claims and illustrated in the accompanying drawings.
In the drawings:
FIGURE 1 is a side elevational View of a latch bolt casing anchored in place by use of one form of the invention in a typical door and which employs the method hereinafter described.
FIGURE 2 is a horizontal sectional view taken on the line 22 of FIGURE 1.
FIGURE 3 is a cross-sectional view taken on the line 3--3 of FIGURE 1.
FIGURE 4 is a perspective view of an anchoring element of the type used in FIGURES l, 2 wd 3.
FIGURE 5 is a side elevational view of a latch bolt casing anchored in a door by use of a second form of the invention.
FIGURE 6 is a transverse sectional view on the line 6-5 of FIGURE 5.
FIGURE 7 is a perspective view of the form of anchoring device used in FIGURES 5 and 6.
FIGURE 8 is a view similar to FIGURE 5 showing the device in a partially assembled condition.
In the embodiment of the invention'illustrated in FIG- URES 1, 2, 3 and 4 there is shown a fragmentary section of a door 10. A transverse substantially cylindrical bore 11 extends from one face 12 of the door 10 to another face 13. A hole forming a second and smaller bore 14 extends inwardly from an edge 15 into and communicating with the bore 11. With respect to the bores just described, they are formed in a conventional manner and have the same relationship as has been in use fora considerable period of time for the mounting of door locks of the cylinder lock type with which this disclosure is concerned.
A latch bolt assembly including a casing 16 is here shown as being substantially cylindrical in cross-section and has an annularplate or flange 17 located at its outer end in a position such that it bears against the bottom of a depression 18 in the edge 15 of the door.
In the latch bolt casing is a reciprocating latch bolt 19, the mechanism of which is substantially conventional.
In the form chosen for the purpose of illustration there is shown as part of the latch bolt assembly an extension comprising parallel plates 20 and 21 which may be secured together by some appropriate device such as a rivet 22 in order to contain a hub 23 to which may be attached a conventional IOU-back cam 24.
The parts identified are those which comprise any one of a number of substantially conventional cylinder latch bolt mechanisms. In the interest of clarity, the operating mechanisms featuring knob and spindle have been omitted.
In order to anchor the latch bolt casing in the position illustrated in FIGURES 1,2 and 3, a loop such as that illustrated in FIGURE 4 and identified by the reference character 25 may be employed. The loop shown by way of illustration is of relatively stilf resilient wire and is provided with bent ends 26 and 27 and includes an areaate portion 28. In'the plate 20 are provided apertures 29 and 3t) into which the bent ends'26 and 27 are inserted. When the loop is assembled with the latch bolt casing the ends 26 and 27 are first inserted into the respective apertures and the loop is then sprung sufiicient to permit the arcuate portion 28 to be pressed into the position shown in FIGURES 1, 2 and 3. As there illustrated, the arcuate portion is received within the innermost end of the smaller bore 14, thereby locking it in place and bears against the junction of the inner end of the small bore 14 with the larger bore 11. 1
When this form of the device is assembled, the latch bolt casing is first inserted in position, as shown in FIG- URES l and 2. It should preferably be pressed as far in as it can be and until the plate or flange 17 is within the depression 18 and bears against the appropriate edge portion 15 of the door. 'I'he loop 25 is then applied as has just been described and when once in position the resiliency resident in the loop will tend to force the extension embodied in the plates 20 and 21 inwardly or in a direction from left to right, as viewed in FIGURES l and 2. This will tend to press the plate or flange 17 against the edge of the door and will firmly anchor the latch bolt casing in proper operative position wherein the requisite operating mechanism can be attached in a substantially conventional fashion.
In a form of the invention illustrated in FIGURES '5, 6 and 7 the same latch bolt casing is mounted in the hole or bore 14 with plates 20 and 21 extending into the midportion of the bore 11.
In order to anchor the casing 16 and attendant 'parts in the position shown there is provided in this instance a wire spring 32 which is shown in perspective view in FIGURE 7. The spring preferably consists of a single length of wire wherein the Wire is turned to form a loop 33 at the mid-portion surrounding a ho1e34. The diameter of the hole 34 is slightly larger than the outside diameter of a rivet end 31 so that the loop 33 can be slipped comfortably over the end of the rivet whereupon the rivet is peened over at its ends to fasten the loop in place. Another fastening method is to force loop 33 to expand over the larger head of the rivet and then to be retained by said rivet head.
When the casing including the latch bolt assembly with the spring 32 attached is to be anchored by use of the spring 32, the spring arms are pressed together and the casing is inserted into the small bore 14 in the same manner as previously described so that the plate or flange 17 is received in the depression 18 and the plates 20 and 21 extend into the bore 11 placing the hub in a substantially central position. The spring 32 slides freely through the small bore as shown in FIGURE 8 until it is entirely within the large bore 11.
Once in position the arms 35 and 36 spring outwardly away from each other and the rounded corners 38 and 40 are forced outwardly into engagement with the wall of the bore 11. As described the spring anchors with sufficient firmness to hold the casing in its proper position until a spindle (not shown) of a conventional door lock can be passed into and through the hub 23, after which the latch bolt casing cannot be removed in the absence of removal of the spindle. On those occasions where it may be desired to remove the casing, removal can be acomplished by the simple expedient of collapsing the arms 35 and 36 against each other by manual pressure aftert he spindle has been removed, and the spring ends started outwardly through the small bore 14, permitting extraction of the casing 16 and its attendant parts.
From the foregoing description of two types of spring member for removably anchoring a latch bolt assembly and casing in a door it can be understood that the physi cal embodiments of devices shown exhibit a method of attachment or anchoring by a spring-like agency, the important aspect of which consists of making use of walls of the bore normally made to receive the parts and pressing against oppositely positioned areas of the door in order to force and retain the latch bolt in position by such agency.
It will be understood from the foregoing description in company with the disclosure in the drawings that there has been provided a latch bolt casing which assumes substantially conventional forms and proportions such as may normally be employed and which needs no special design or construction other than the simple expedient shown in order by use of a simple anchoring element to be firmly anchored in place upon the material of the door itself.
