the gasket faced edge et the holder the only i i chamber wall contacting part, as shown in Fig. l.
Spring lingers lo oi sheet-metal provided on the outer :tace oli the holder above and below its opening :for bearing et the outer wall of the chamber il when the dust-guard is inserted therein, and serve to force the gasket faced edge ci holder irmly against the opposite wall the chamber. These ngers are shown as being secured to the holder by projecting tongues lo from the opposite side edges thereof through registering slots. in the holder members 8, 9 and bending such :iingers over the edges oi the slots.
The telescoping o'l the outer edge porv tions of' the holder members 8, 9 and thlling of the recess 13 with the gasket l prevents dust and dirt from entering an collecting between the holder members. l case any dirt should from any cause ente;I or accumulate within the holder chal ber it is permitted to pass thereirom tafough one or more openings l? in the inner holder side at the bottom portionoj the chamber 5. To facilitate such disc larg lig-action bottom portion of the chamber wail in which the openings 17 are disposed is downwardly inclined in both directions toward the center, so that a jarring action oi the holder will tend to worlr the dirt toward the discharge openings.
The collar o, which is preferably oi pressed or vulcanized iiber, is smaller in size than the chamber o of the holder to enable the collar `to have limited vibratory inovements therein 'transversely oi its openingl axis, and the outer edges of the collar are preferably substantially rectangular in torna or of some other suitable shape adapted to Yprevent a complete rotation of the collar within the chamber. The collar is flat in form and is oi a thickness to adapt it to snugly lit between the side walls ott the holder recess 'or irictional Contact there with, whereby the collar is yicldingly held in suspension by the holder in any position to which it may be moved by the vibratory action of the journal, rEhe suspending of the collar in this manner prevents itV vfrom bearing, by reason ci its weight, on the journal., and prevents an oblong wearing ci the collar opening. lt also reduces the wear of the parts 'to a minimume To adapt the holder portions l0, l0 to have a yielding or resilient bearing against the collar, the space therebetween is norm ally less than the 'thickness of the collar o to cause a slighL springn ing apart of said portions by the collar when inserted therebetween.
llt is :found in practice that the l'rictional sliding action of the collar within the chainber is facilitated by providing each wall oi the chamber with an initial recess or groove @nasa-inra serves to strengthen such walls as by tongueand--groove dovetailedfjointsf` at the corner portions of the collar, as shown at .'19, that such sections, when disposedwithin the holder, work together as a unit, the same as though the collar, were in one piece. The making of the collar in this manner ctie/cts a very material saving in the cost of manufacture, especially if vulcanized fiber used, such. material is expensive, and the waste incident to the cuttingv out of the collar ooonings would be considerable.
'ihe collar 6 is made yieldingly eXpansibleby' providing a loose connection be tween i'nembers of' one of the joints 19, as at 191, which permits a limited outward movement ci the interengaged parts of the joint. This feature is found in practice be quite important, as it allows for an easier insertion. of a journal through the collar than would otherwis be the case,
The tendency of the collar is to remain in its contracted form with the ends of the sections in abutment, as the normal size of the collar opening is suiiicient to '.tit loosely around` a journal of standard size and there will be no binding of the collar on the journal, unless it is rusted or slightly larger than the standard.
l wish it understood that my invention is 'not limited to any specific construction or arrangement of the parts as numerous modifications can be made within the spirit thereof.
Having thus described my invention, what l claim new, and desire to secure by Letters Patent, is,-
l. ln a dust-g' xrd, a holder having opposing side members cooperating to form a collar-receiving chamber and having' the outer edge portion VLhereof projecting one without the other .o the same ldirection transversely oi' theholder body to form an endless edge bearing {ia-nge.
2. ln a dust-guard, a holder having opposing side members cooperating to form a collar-receiving chamber and having outer edge portions thereoicooperating to form a transversely opening gasket receiving recess.
3. ln a dust guard, a holder having opposing side members provided with registering journal receiving openings, said members being spaced apart at their inner edges to .form a collar re eiving chamber, the side members without said chamber being rigidly .especially where the journal might be rusted.A
