(o1 j.';a9 2'-,-3 )f invention r'elates to improvements in box strikesfor locks and has particular reference to an improved adjustable 'metal keeper box for locks. i The primary object of this invention is the provision of an improved keeper box for the bolts of locks which is practical in construction and may with facility be adjusted to vary ing sizes in order that the same may be accurately set intoplace in a mortise of the door jamb, and so that a manufacturer neednot carry a large variety offkeeper boxes of different lengths to suitmortise locks of various sizes. I
Other objects and advantages of this invention will be apparent during the course of the following detailed description.
In the accompanying drawing, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views,
Figure 1 is a cross sectional view taken through a door jamb and adjacent closure in which a mortise lock is positioned showing in the door jamb the improved adjustable box of the lock strike, adjusted to suit the size of the particular mortise lock used.
Figure 2 is a view similar to Figure 1 but showing the application of the same adjustable 30 strike box to a mortise lock of smaller size than that shown in Figure 1.
Figure 3 is a perspective view showing an extended position of the two telescopically related members or sections making up the adjustable keeper box.
Figure 4 is a transverse sectional view taken through the box substantiallyon the line 44 of Figure 2.
In the drawing, wherein for the purpose of illustration is shown only a preferred embodiment of the invention, the letter A may generally designate the improved adjustable keeper box adapted to be used in connection with a conventional strike plate B to make up the keeper or lock strike construction which is mortised in the door jamb C. With this improved lock strike a mortise lock D located in the closure or door E may be used in the usual manner.
Referring to the adjustable box A, it is to be understood that it is within the contemplation of this invention to have the strike completely adjustable. However, in the example shown, the lock plate B is not adjustable. The box A preferably consists of telescopically related sections 10 and 11. They each include aback-wall 12 and side walls 13 and 14 and one end wall 15. The adjacent telescopically related ends of the sections '10 and 11 are open and-the section 10 is adapted to be telescopically slid into the open end of the section 11 with'the walls 13 of the section in abutment; the walls 12 of the sections in abutment, and the walls 14 of the sectionsin abutment. In order to prevent relative tipping of the box sections and to insure-a true rectilinear movement of thesections for accomplishing thesliding adjustment to the desired size, the side walls 13 and 14 of the section 11' are provided with internal ribs' 20 extending from the open end of the section 11 along the said walls 13 and 14 for substantially over half the length of the section 11 parallel with and spaced from the inner surface of the wall 12. These ribs 20 are preferably stamped into the side walls; the entire box A being preferably constructed of stamped sheet metal, although the invention is not to be limited to any particular method of forming the box since cast metal boxes may be used in lieu of the stamped metal box. The sidewalls 13 and 14 of the box section 10 are provided with grooves 21 upon the outer side surfaces thereof, and preferably for theentire length of the section 10, in spaced relation from the back wall 12 and paralleling the same so as to receive in complementary manner the ribs 20 of the box section 11. Thus, when the sections 10 and 11 are assembled the ribs 20 slide in. the grooves 21 and maintain the walls of the box sections in intimate sliding contact against relative tipping of the said sections. The end walls 15 of the box sections are of course provided with attaching flanges 25 with slots 26 opening at the ends thereof adapted to receive retaining screws or like elements by means of which the sections of the keeper box are assembled upon the jamb.
A manufacturer of lock strike boxes is com- 'pelled to have many varieties and sizes of strikes for different size locks. With the improved adjustable keeper or strike box the prob lem for the manufacturer is materially simplifled since in lieu of carrying in stock some fifty or more sizes it will only be necessary to carry three difierent width sizes; the length of the box being adjustable for practically any height .or length of look. For the installation the im-- proved adjustable lock strike box is an improve ment in that the same may be made to fit efli ciently in the mortise of the jamb and the strike plate may be applied in proper relation thereto.
As to the assemblage the sections of the box are placed in the jamb cut-out or mortise as shown in Figures 1 and 2 of the drawing, and after application of the strike plate B the screws 30 will hold the box A in proper position. It is readily understandable that the lock plate may be made as part of thekeeper box although we prefer to use a separate strike plate for each box in the manner shown in the drawing.
The parts of the lock strike box will not be come disassembled during shipping and ham dling since the rib and groove construction of the sections enable themto be properly assembled in telescopic relation. 1
Various changes in the shape, size, and arrangement of parts may. be made to the form of invention herein shown and described, without departing from the spirit of the invention slotted openings of the box sections for attachment to a support for assembling the strike plate over the box sections with the latter held in definite relation.
2. A strike for locks comprising a pair of telescopically connected box sections each having a rear wall, side walls and an end wall, the adjacent ends of the sections being open and the said box sections at the frontbeing open in the same direction, means rearwardly of the front edges of said box sections connecting them for definite rectilinear sliding adjustment, all front edges of said sections lying in the same plane, a strike plate, and means for fixedly conmeeting the plate and the said box sections to a support with the plate in contact with the front edges of both of said box sections.
3. A mortise box forlock strikes and the like comprising a pair of telescopically connected sections each having a rear wall, side walls, and
one end wall, the adjacent ends of the sections being free of end walls and slidably connected together so that the size of the lock strike and the compartment thereof may be varied, the sections being open at the front to permit entrance of a lock bolt to the compartment thereof, said sections on the side walls rearwardly of the front edges having tongue and groove connections holding the same in nontipping relation to permit rectilinear adjustment.
