To secure the locking member assembly in the cylinder, portions of .the cylinder are swedged over notches in the outeredgesoi thetcageside wallsasat 21. I k
If desired, a single-spring l9.- located atthe center of the locking bar may: be used, asillustrated in Figure 6, in placeof the twosprings l9, In this embodiment of the invention, the over: hanging tongues l8 on the end wallsof the cage by engaging the stepped portions I 1 ';serve to limit the movement of the bar with respect to thecage under action of the spring tW-when the locking means is removed from the cylinder andthus takes the place of the tangli projecting into the aperture l5. v, I p 5 In the embodiment of the invention illustrated inFigures 7, 8 and 9, thelocking means consists of a bar 28 slidableradially in a pocket formed in the cylinder .to be projected by the key op-f erable tumblers into operativellocking engage-,- mentin the' groove 26. I To retainthe locking bar 28.,assembled with the cylinder, a retaining member 30 in the form of a U-shaped clip having spring arms,fis en} gaged over the central portion of the bar and received in guide'grooves 3| in the side walls of the pocket 29. As stated, the arms of the retain: ing member 35 are spring tensioned and oneof the arms'has a hook 32, which engages over an abutment 33 at the inner end of one of the grooves 3|, the. extremities of the arms being-inclined as at 34 to facilitate engagementof theretaining member with thecylinden p a The central portion of the bar 28 adjacent=the retaining member 30 is cut out as at 35 anda spring 36 is confined between the bottom of the cut-out portion 35 and theclosed:outer.end-31 of the retainingmember, so that the bar 28 is yieldably urged inwardly towardlthe key operable tumblers. w To improve the operation of the lockand pre clude sticking, the bar 28 males at its inner edge a roller 38 which engagesitheadjacent edges of the tumblers and thereby reduces the degree of friction between the tumblers 'and the-locking bar. a To mount the roller; trunnions 39 extend from its opposite ends to be received in notches 40 When projected formed in arms 4| projecting from the bar, and to retain the roller assembled with the bar, the inner ends of the arms of the retaining member 30 are extended inwardly as at 42, the space therebetween being less than the adjacent reduced diameter of the roller so that when the retaining member is in its normal position, the roller is held against detachment from the bar.
Obviously, the provision of the roller reduces the iriction in the engagement between the locking means and the tumblers and thus aflords a smoother operating lock."
, In the embodiment of the invention illustrated inFigures 10, 11 and 12, the cylinder construc- Jtion as well as that of the, mounting member, is the same as described in conjunction with the f embodiment of theinvention illustrated in Figurefl but the locking means per se is of different construction.
The springs l9 are comparatively, light and Thelocking means in this embodiment of the inventionis indicated generally by the numeral 45. It comprises a solid locking bar 45 substantially rectangular in cross section with one edge 41 vr-shaped tofit in the V-shaped notches of the key operable tumblers; Like the locking bar l2," which is employed i'nthe modification shown in Figure 1, the bar 46 has its opposite ends stepped as at 48 to provide-abutments or projections against which expansive" springs "49' en'- gage to= yieldingly I urge the 'locking bar toward the tumblers. i
The-opposite endsof'the springs bear against walls 50 and 5! which form-part of a housing orr'cage 52 stamped from a single piece of sheet metal; a
TheLhousing or cage 52 is substantially channel-shaped in-cross section-with its web cut out to permit the projection of the locking bar 46 therethrough. Theportionsof'the webof the housing orcage which remain at the opposite ends of the opening through-which the bar projectsiform' the walls" and 5|; The distance between -the'v inner edges of these "walls 'is but slightly greaterthan the length of the; adjacent portion fofthe' bar and as clearly-shown in Figure 10, the opposite ends of this portion of the bar have'overhangingledges 53 to engage the wallst50 and-Stand prevent disassembly'ot the locking bar from the housing or cage. I
Assembly of the 'pa'rtsisefiected by forming the wall 50'with 'a tongue 54"whl'ch, prior to assembly. is bent out'of' the plane of the channel web to increase the distance' between' the inner edges or thewalls'50 and 5 l and permit the passageof .the'locking bar therebetween. 'Mter assembly,-'the tongue 54 1s bent back into" place to'engage'under the'adja'cent ledge 58. It is to "be observed that the housing or cage 52has a-flan'geSSabout its'entire periphery and that at its-opposite ends' it has sidew'ise projectionsii'to-add strength to the structure and permit its formation from a single *piece of sheet I v v The assembly of the 7 locking means withthe cylinder-is efiected in-a manner similar to that hereinbefore described. The "cylinder wall is provided with a pocket conforming in size and shape to" thesize of the housing 52 into which the housing is pressed, and if desired the cylindermay'be staked overthe' ends of the housing as shown in Figure 11'.
