STRIKER OR KEEPER FOR LOCKS Filed Oct. 4, 1933 INVENTOR Herman Hansen M M ATTORNEYS Patented Aug. 3, 1937 PATENT OFFICE STRIKER OR KEEPER FOB LOCKS Herman Hansen, New York, N. Y., assignor to Francis Keil & Son, Inc., a corporation of New York Application October 4, 1933, Serial No. 692,159 23 Claims. (Cl. 292-340) This invention relates to a. strike or keeper construction receiving the bolt of a lock and more particularly to a construction of this character adapted particularly for heavy-duty lock and keeper constructions or installations.

One of the objects of this invention is to provide a keeper construction which will be capable of rapid and inexpensive manufacture and which will be well adapted to meet the varying conditions of hard practicaluse. Another object is to provide a construction of the above-mentioned character which will be durable in construction, capable of rapidity and ease of installation and capable of being readily and reliably set not only to meet variations in types of bolt or lock constructions with which the keeper is adapted to coact but also to meet variations in the requirements of the particular installation, such as variations in the degrees of offset between the plane ofthe door and the plane of the frame or wall in which the door is set. Another object is to provide a keeper construction that will realize such objects as those above noted and yet be tamper-proof and safe in action and construction. Other objects will be in part obvious or in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the application of which will be indicated in the following claims.

In the accompanying drawing in which is shown one of the various possible embodiments of this invention,

Figure 1 is a top plan view of a keeper and lock installation as the same is seen when viewed downwardly, with the top swinging toward the observer;

Figure 2 is a central longitudinal vertical sectional view of a striker construction such as that shown to the left in Figure 1;

Figure 3 is a view as seen from the top in Figure 2 or as seen from the top in Figure 1, and

Figure 4 is a view like that of Figure 2 illustrating another embodiment of certain features of my invention.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Referring now first to Figure 1, there is there shown a wall or frame Ill having a door-opening which is closed by the door H suitably hinged (not shown) to the wall or frame I0. Illustratively, the membersJll-ll may be considered to be parts of a large refrigerator chamber. The door may be interfitted with the wall or wall opening in any suitable manner and it may or may not have a wall overlapping flange H in either case, the relation between the plane ll of the outer face of the door I I and the plane lo of the outer face of the wall or frame I0 must be considered and dealt with in interrelating a keeper or striker on the member l0 and a lock with a bolt on the member II, to achieve the desired coaction between the keeper and the bolt. One of the dominant aims of the invention is to meet the widely varying practical relations that exist between a door and door frame and still achieve proper coaction between the striker and bolt.

Illustratively there is mounted upon the outer face of the door II a lock construction which may be of any suitable construction and which for purposes of illustration may include a suitable casing or frame l2, suitably secured to the door II, and provided with a bolt I3 adapted to be controlled or actuated in any suitable manner; illustratively the bolt H is a latch bolt and is pressed outwardly of the casing l2 by means of a spring (not shown) and is adapted to be withdrawn by a handle, such as the handle I4 movably mounted with respect to the casing l2, as by a pivot pin Hi.

The bolt I3 is to coact with a keeper construction which includes a keeper member I6 positioned in the path of movement of the bolt l3 when the door H is swung toward closing position and a frame or supporting structure, generally indicated at H, for the keeper member IS, the bolt I3, where it is a latch bolt, being, by reason of its spring mounting, adapted to be forced inwardly into the casing l2 as the bolt l3 strikes the keeper member l6, so as to by-pass the keeper member I6, whereupon the spring or other mechanism forces the bolt I3 into the position shown in Figure 1, in back of or underneath the keeper member 16. The latch bolt l3 has a curved face I3 to bring about the desired coaction with the keeper member l6 to achieve retrograde movement of the bolt and if desired a roller ill (see also Figures 2 and 4) may be mounted in a recess IS on a small shaft 20, to be struck by the curved face l3 of the bolt l3 and to coact therewith in forcing the bolt into the casing and thus achieve a by-passing of the keeper member I6 itself.

The keeper member I6 is preferably of relatively short vertical height and is preferably of substantial length in a direction toward the lock construction I2, thus extending crosswise (as viewed in Figures 1, 2 and 4) of the supporting frame structure I1, being, moreover, so related to the latter that its spacing from the plane IIJ of the wall or door frame I0 may be changed, at will, in a manner more clearly described hereinafter.

The supporting structure I1 includes a base member 2I adapted to rest against the plane l0 of the part 'I 0 to which the keeper construction is to be secured and has integrally formed therewith two laterally spaced upstanding members 22 and 23 (Figure 3), the spacing of these members providing a vertically extending slot 24 facing toward the right, as viewed in the drawing, and a vertically extending slot 25 facing toward the left, as viewed in the drawing. If desired, the members 2223 may be curved toward each other, at their left-hand portions, as viewed in Figure 3, as is indicated at 22 and 23, respectively, in order thus to make the slot 25 of lesser dimension than the slot 24.

The keeper member I6 extends into both slots 24 and 25 and is received between the vertical spaced members 22-23, being suitably shaped to fit into the large slot 24, with the roller-carrying part projecting to the right out of the slot 24, and having a vertically extending rib I6 received in the slot 25. With such interfitting of the keeper member I6 with the members 2223, the member I8 is held against rotation by the vertical axis and is reliably guided in whatever up and down movement relative to the supporting frame I1 that is given it, as hereinafter described.

Referring now more specifically to Figure 2,

there is bridged across the members 22-23 and integrally formed therewith a web 26 preferably of substantial thickness; web 26 is providedwith a threaded vertically extending opening 26 in which is threaded the threaded end 21 of a combined supporting and adjusting member 21 whose other and upper end 21 is also threaded, being threaded into a threaded hole I6 provided in the under face of the keeper member I6 and extending thereinto throughout a substantial extent, as is indicated in Figure 2.

The respective halves or end portions of the member 21 are oppositely threaded; for example, the portion 21 may be given a right-hand thread and the portion 21 may be given a left-hand thread, of any suitable or desired pitches. Illustratively, the portion 21 may have a coarser or greater pitch of thread than the portion 21 as indicated in Figure 2.

Intermediate of the threaded ends and hence, when assembled, intermediate of the keeper member I6 and the web 26, member 21 is provided with a collar portion 21, the latter being in turn provided with a suitable number of radially extending openings, two of which, 21 and 21, are indicated in Figure 2.

Accordingly, if a suitable bar or rod is fitted successively into the radial openings 21, 21 etc., and the member 21 correspondingly rotated, the member 21 partakes of movement of translation relative to the supporting structure I1 and the keeper member I6 partakes of motion of translation relative to both the member 21 and the frame structure I 1, and, depending upon the direction of rotation of member 21, these motions of translation are either up or down. But in either case, the up and down movement of the keepermember I6 is a compound movement and, due to the threaded relation therewith of the threaded portion 21 of the member 21, a greater up or down movement is given the keeper member I6 than is given the member 21 for any increment of rotation imparted to the latter. Thus a rapid change in the spacing of the keeper member I6 from the plane III of the frame or wall III to which it is secured and hence a rapid determination of the desired relation of the keeper member I6 to the bolt I3, to meet the conditions of installation or the varying offsets between door and door frame met with in practice, achieved. j

Moreover, the member 21 aids in maintaining a,

rigid and properly alined relation of the keeper member IS with the supporting structure I1, throughout the range of change of position of one relative to the other, while the relatively wide slot 24 (see Figure 3) permits ready access to the apertured collar 21 and permits'of a wide angle of swing of the rod or implement used to rotate the member 21. Moreover, when the door II is closed, as shown in Figure 1, the lock construction or casing I2 and related parts, and particularly the bolt I3, are in position to block access to the operating collar 21, thus precluding tampering with the keeper member I6 when the door is closed and the bolt I3 locked against movement as by any suitable key-controlled mechanism.

In order to preclude up and down movement of the member 21, as well as to preclude rotation thereof, I provide a disk-like member 28 (Figures 1, 2 and 3) provided with a rib 28 (Figures 2 and '3) that extends into the slot 25 between the spaced members 22-23, member 28 being thus precluded from rotation so that its lateral portions 28 and 28 (Figure 3 and see also Figure l) are dependably held in engagement with the outer or lateral faces of the spaced members 22--23, respectively; member 28 is apertured (Figure 2) and through it passes a screw 29 that is threaded into the keeper member I6.

Having set the keeper member I6 at the desired relative position to the supporting frame I1, the screw 29 is tightened up, whereupon the members 22 and 23, and particularly the portions 22 and 23, respectively, thereof, are securely clamped between the keeper member I6 and the disk-like member 28, member I6 being thereby anchored against further up or down movement relative to the supporting frame l1, and thus also coacting with the member 21 to rigidly support the elongated keeper member I6 and to eifect a reliable transmission from the keeper member I6 to the supporting structure I1 of any strains, stresses, or blows that are caused by the coaction of the bolt I3 with the keeper member I 6.

Conveniently, also, I provide a set screw 30 (Figure 2) threaded into the web 26 and adapted to abut against the threaded portion 21 of member 21 in order to rigidly lock the latter to the supporting frame I1 and thus cause the member 21 better to support the keeper member I8 and to take part in transmitting to the frame I1 any such stresses or blows as are above mentioned.

Any suitable means may be employed to secure the frame structure I1 to the wall III but in accordance with certain other features of my invention, I prefer, in order to achieve certain other important results and advantages, to employ a securing arrangement which I describe in detail hereinafter.

Turning now to Figure 4, the keeper member I6 above described will be seen to be again pres- I ent and also the supporting structure I1 thereof,

as also above described; however, interposed between the web 26 and the base portion 2| of the frame structure I1 is a threaded collar 32 provided with suitable radially extending openings, two of which 32 and 32 are shown in Figure 4, whereby a suitable rod or implement may be inserted and the threaded collar 32 rotated, the slot 24 between the spaced members 22 and 23 permitting access to the collar 32 and permitting of a relatively wide angle of swing of the implement.

The web 26 has a vertically extending round hole 25 in which is slidably received a rod or post 33 having a threaded portion 33 extending through and in threaded engagement with the threaded collar 32, base portion 2| of the frame 1 having an aperture 2 into or through which the post or rod 33 may pass; the upper end 33 of the rod 33 enters into a hole l6 on the underside of the keeper member 6 to which it is rigidly secured in any suitable manner, as by way of a pin 34, for example.

Accordingly, rotation of the collar 32, in the manner above described, effects a raising or lowering of the keeper member l6 relative to the spaced members or parts 22-23 of the frame |1, depending upon the direction of rotation of the collar 32, and thus the desired setting of the keeper member I6 may be achieved, whereupon the screw 29 may be tightened up to bind the keeper l6 to the frame structure 1. as will now be clear. Furthermore, the collar 32 snugly fits in the recess |1 between the parts 2| and 25 and aids in holding the keeper member IS in the set Position.

Any suitable means may be employed to secure the keeper structure ,-|6|1 to the wall but, as above noted in connection with the form of my invention shown in Figure 2, I prefer to employ, in order to achieve certain other important features and results, a special kind of fastenmg.

Considering now these other features of certain aspects of my invention as those features are typified in the embodiment shown in Figure 4, I provide the wall Ill with a hole Ill passing entirely through the wall, hole Ill being in alinement with the hole 2| in the base portion 2| of the frame l1; the rod 33, where I desire to achieve these additional features, is provided with an extended portion 33 which passes through the hole Ill and conveniently this portion 33 forms a threaded extension of the threaded part 33" with which the threaded collar 32 coacts as above described.

The extension and hence the extreme end of the rod 33 is thus made to project beyond the inner face of the wall III and onto it is threaded a nut 35, a washer 36 being interposed between the nut 35 and the wall Ill".

The setting of the striker member l6 relative to the frame structure U (Figure 4) proceeds in the manner above described and when the setting is completed and the set screw 29 driven home, the nut 35, provided with a forked handle 31, whose arms engage on two sides of the nut 35 and are pivoted thereto by pins 38, is then tight ened up.

Upon tightening the nut 35, a number of highly advantageous actions result. Firstly, the keeper construction |6|1 is securely clamped or mounted onto the wall I0, the base portion 2| thereof being provided with a suitable number of downwardly directed studs, two of which are shown in Figure 4 at 2| and 2|P, being received in suitable holes drilled into the outer face of the wall I0 and thus precluding rotation of the keeper construction |6|1 about the axis of the securing and clamping rod 33.

Also, the clamping action achieved by the manipulation of the nut 35 is such that the wall Ill and the base portion 2| are clamped between the nut 35 and the threaded collar 32, the clamping pressure thus exerted through the collar 32 acting virtually to lock the latter against manipulation or rotation. Also, any stresses, forces or strains exerted upon the door or upon the bolt |3 to force or swing the door II in opening direction will be seen to be transmitted by the keeper member l6 directly to the rod 33, the latter thereupon acting as a tension member and thus the full strength of the wall ||l itself is brought into play in resisting any attempt to force the door open.

Still referring to Figure 4, should a person he accidentally or intentionally locked inside the chamber of which the door N forms a part, the imprisoned individual has accessible to him the handle 31 which, when manipulated in a direction to remove nut 35 from the innermost end of the rod 33 results in freeing the rod 33 and the keeper structure |6|1 at its outer end so that the imprisoned individual may thereupon either push the rod 33 through the hole III or simply push the door open, thus detaching keeper structure |'6-|1 and rod 33 from the wall and permitting easy opening of the door and escape from imprisonment.

Recurring now to the form of my invention shown in Figure 2 and considering now the preferred manner of attachment thereof when I desire to achieve the above-mentioned additional results and advantages, the wall M is again provided with a hole II) in alinement with an aperture 2| in the base portion 2|, and the member 21 has secured thereto or integrallyformed therewith an extension or rod portion 21 threaded as at 21 throughout a substantial portion of its length, the free end of the rod-like extension receiving the nut 35 which, as is the preferred arrangement as noted in connection with Figure 4, is provided with the permanently-secured handle 31.

After having set the keeper member i6 relative to the frame structure H, as earlier above described in connection with Figure 2 and the parts locked as by the screws 29 and 30', it will be seen that the locking of the parts also holds the extension 21 against rotation, particularly due to the actiorfof the set screw 30, and ac cordingly the nut 35 may now be tightened up and the structure |6-|1 rigidly secured in place, the wall In being reliably clamped between the nut or washer and the base portion 2| of the frame |1.

Here again, numerous advantages and coactions are achieved. A very substantial rigidity is achieved and the keeper member I6 is thus well adapted to stand the shocks and strains and stresses to which it is subjected in normal use. Furthermore, any abnormal stresses such as would be incurred if it were attempted to force the lock construction, are transmitted from the keeper member Hi to the member 21 andby the latter to the wall l0, member 21 functioning as a tension member and acting also to relieve the frame structure H from being subjected to such abnormal strains. Also, the safety-release feature above pointed out in connection with Figure 4 is hereby achieved in that a person locked inside may easily manipulate the handle 31 to cause a detachment of the keeper structure ||i|1 from the wall Ill and thus permit quick access to liberty.

Thus, it will be seen that there has been provided in this invention a keeper construction in which the various objects above noted, together with many thoroughly practical advantages are successfully achieved. It will be seen that the construction is thoroughly practical, is strong and durable, and is capable of inexpensive manufacture. Moreover, the construction will be seen to be foolproof though readily and quickly capable of meeting. the many varying conditions of practical use, be such conditions caused by differences in degrees-of offset of doors with respect to door frames or walls, or by differences in latch or lock constructions that may be related to the keeper, or by warping, shrinking, or other structural changes in the course of the life of the door or walls with which the parts are associated.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
