Said casing receives a plied in an attempt t0 destroy the lock. i radial bolt 5 having an end portion outwardly It isimportant to note that the above mentione projecting through the peripheral face 1b, and construction has been designed for application spaced slightly from the shoulder 2. Said bolt, to both spare wheels and running wheels, and in 45 which is preferably a sheet-metal stamping, has order to accommodate the latter wheels of modan approximately central opening 6 in which is ern design, it has been so constructed as to prodisposed a coiled spring 7, urging the bolt outvide a minimum outward extension of the wheel wardly. The inner end of said spring seats upon hub shell 12 to thus minimize possibility ofthe shoulders 8 formed in the casing 4 at front hub cap striking against objects during the op- 50 and back of the bolt 5. The bolt opening 6 exeration of the vehicle of which it forms a part. tends inwardly beyond said shoulders to receive Particularly in view of the fact that in modern a pin 9 terminally and eccentrically carried by a wheels of the type shown the wheel axleorspinlock barrel 10, containing any suitablev and welldie 15, as the case may be, depending upon known arrangement of key-actuable tumblers whether it is a driving wheel or not, may extend 55 to and even beyond the outer edge of the shell l2, and where the wheel is not a driving wheel the hub 16 may be provided with a grease sealing cap 17 enclosing the outer end of the axle 15 and the securing nut 18 and projecting outwardly beyond the end of the axle 15, the problem of preventing an excessive outward projecting of the hub cap beyond the outer end of the hub shell offers certaindifllculties of attainment that have heretofore not been met. A
It will be observed that these problems have been met in the construction described by positioning the lock casing 4 and the lock barrel 10 carried by it radially-between the shaft 15, hub 16 and/or cap 17, and the inner edge of the ange 13, thus permitting the casing 4 and barrel 10 to project axially inwardly of the outer ends of these parts in spite of the fact that they may project axially outwardly beyond the end of the hub shell 12. Although this feature renders the casing 4 and lock barrel 10 an eccentric mass which would cause hopping of the associated wheel when running at high speeds, the possibility of such an undesirable effect is eliminated by the provisionv of the counterbalances 11a.
'I'he reinforcing ribs 3, in order to enable achievement of the advantages above set forth, are curved' in the manner shown so as not to interfere with the proper reception of the axle 15, hub 16 and/or cover 17 as the case may be in the hub cap, and it will be observed in the particular construction shown that the counter weights lla are formed as a part of the ribs 3, thereby reinforcing the same and enabling less metal to be used in the whole structure, and additionally the ribs 3 and counter-Weights are formed as extensions of the teethor lugs 11, or the teeth or lugs 11 as extensions ofv them, and therebyserve to reinforce them in a material and efficient manner.
while a is apparent that the'iuustrated embodiment of my `invention is well calculated tol adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to and change within the spirit and scopefof the subjoined claims. f
What I claim is: y
1. In combination, a rotatable wheel hub shell having' an open end, an inturned flange portion on said shell defining said opening, a wheel axle positioned centrally of said shell and terminally projecting axially approximately into the plane of the inner margins of said flange, a cover for said opening, rigid means fixed to said one side thereof and arranged for interlocking engagement withl said flange to lock the adjacent portion of said cover against axialdisengagement with respect to saidflange, a lock barrel mounted on the diametrically opposite side of said cover from said means and projecting inwardly from the outer face thereof to a point axially inwardly beyond the end of said axle, a bolt carried by said cover in position to engage said flange and operable through said barrel to releasably lock said opposite side of vsaid cover against axial displacement with respect to said flange, and means carried by said cover for counterbalancing the off center weight of said locking means during rotation of' said shell and cover.
2. In combination, a rotatable wheel hub shell having an open end, an inturned flange portion on variation, modification o cover at said shell defining sai-d opening, awheel axle positioned centrally ofsaid shell and terminally projecting axially'app'roximately into the plane of the inner margins of said flange, a covei` for-said opening, rigid vmeans fixed to said cover 4at' :one
side thereof and arranged for interlocking`enthe adjacent gagement with said flange to lock portion of said cover against axial disengagement with respect to said y the inner face of said cover at that edge thereof diametrically opposite said means and extending axially inwardly of said shell between said-shellY and axle, a lock barrel housed within saidzpro-J/ on said shell defining said opening, a wheelaxle positioned centrally of said shell and terminally projecting axially approximately into the' plane of the inner margins-of said flange, a cover for said opening, rigid means ilxed vto said cover at one side `thereof and arranged for interlocking engagement with said flange to lock the adjacent portion of said cover against axial disengagement with respect to said flange, a protuberance on the inner face of said cover at the edge thereof diametrically opposite said meansand extending axially inwardly of said shell between said shell and axle, a lock barrel mounted on the diametrically opposite side of said cover from said means and projecting inwardly from the outer face thereof to a yond the end of said axle, a bolt carried by said cover in position to engage said flange and operable through said barrel to `releasably lock said opposite sideof said cover against axial displacement with respectrto said flange, and means carried by said cover for counterbalancing the .off
center weight of said locking means duringrotation of said shell and cover, the last mentioned means projecting into the space radially between said shell and axle.
4. A hub cap adapted to be secured to` the yin flange, a protuberance on' point axially inwardly beturned end flange portion of av wheel hub shell comprising a body portion,l rigid means fixed to y said body portion 'at one side thereof and arranged for interlocking engagement with'said hub flange to lock the adjacent part of said body portion against axial displacement with respectto said flange, a lock barrel mounted on the di-` ametrically opposite side of said body portion from said means and projecting inwardly from the outer face thereof, a bolt carried by said body portion in position to engage said hub flange and operable through said barrel to releasably lock said opposite side of the body portion against axial displacement with respect to said flange, and means carried by said body portion for counterbalancing the off-center weight of said locking meansgduring rotation of said hub shell and body portion. y l
