;. STEPHEN F. BRIGGS, OF MILWAUKEE, WISCONSIN, ASSIGNORTO BRIGGS AND STRAYITON CORPORATION, OF MILWAUKEE, WISCONSIN, A CORLPORATION OF DELAWARE LOCK -- Application filed June 23, 1928. Serial No. 287,794.
This invention has for an objectthe provision'of an improved lock of inexpenslve structure in which the lock cylinder and cylinder mounting head is protected against 1ntentional injury by an outer protective housing. s
A more specific object of this invention reand more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.
In the accompanying drawings, I have illustrated two complete examples of the physical embodiment of my invention constructed according to the best modes I have so far devised. forthe practical application of the principles thereof, and in which: H
' Figure 1 is a side elevational view, with parts broken away and in section, illustrating a lock structure embodying my inven tion, and Figure2 is a view similar to Figure 1 illustrating a slightly modified form of my in vention.
Referring now more particularly to the accompanying drawings, in which like numerals designate like parts throughout the several views, 5 designates a' lock cylinder mounting head having a central bore 6' extended throughout the major portion ofits length and closed atits inner end 7, there being a' transverse bore 8 communicating with the inner end of bore 6 and intersecting its axis. One end of the bore 8 communicates with the periphery of the mounting head 5 to permit thefprojection .therebeyond of the end 9 of a locking pinor bolt 10 reciprocally mounted therein; The bolt10 is preferably of cylindrical form having its medial portion milled or otherwise cut out, as at 11, and its inner end 12 counterbored to receive one end of a spring 13, the other end ofwhich abuts the closed end of bore 8 to normally urge the locking bolt outwardly of the head 5. The bolt is actuated against its spring 13 to retract its end inwardly of the periphery of the mounting head 5 by a cam or projection 14 on the inner end of a lock cylinder 15 of conventional construction and rotatable within the bore 6. The cylinder carries suit able tumblers 16 which are normally spring urged to engage in a longitudinal s1ot'l7 in the wall of the bore, the tumblers being retracted within the plane of the cylinderby the insertion of a proper key 18 in its conventional key opening,inot shown. A The outer end 19 of the cylinder extends beyond the outer end of head 5 and fitswithin a sealing cap 20 connected therewithefor rotation by a projection or lug 21 on the outer end of the cylinder and engaged in one end of the cap key slot or opening 22which aligns with the key receiving openingof the cylinder; The cap has an annular flange or shoul der 23 over which extends an'annularffiange or rib 24 struck inwardly from the outer end of a casing 25. 1 i
The inner end of the casing, in that form v of my invention illustrated in Figure 1, is laterally flanged, as at 26, and fitted within a counterbore 27 at the base of the outer reduced portion 28 of the head 5 and there secured by spinning or crimping the material thereover, as at 29. i v j In that form of my invention illustrated in Figure 2, the casing'25 is of the sameexing the shoulder of the cylinder, and a second shoulder on said member with which the flange of the mounting member is engageable to connect the member with the mounting member.
9. In a look, a bored mounting member, a flange on said mounting member, a rotatable cylinder in the mounting member bore having a shoulder, a member retained by the mounting member flange and having shoulders and means cooperating with the shoulder of the cylinder and said last named member to segure the cylinder in the mounting member ore.
1 In testimony whereof I have hereunto affixed my signature. 7
