PaitentedApr. 8, 1913.-

Application filed September 21, 1912. 'Serial No: 721,710.

The invention relates to improvements in demountable rim locking apparatus and has particular reference to a lock provided with a supporting means rigidly mounted on a fixed annular rim, a means mounted in said rim and engaging said lock for placing into position a float ring capable of expansion and contraction for holding permanently into position a demountable rim structure.

In the following is described in connection with the accompanying drawings one embodiment of the invention the features thereof being more particularly pointed out hereinafter in the claims. I

In the drawings Figure 1 is a cross sectional view of the fixed rim and demountable rim and a vertical-sectional view partly in elevation of the locking means thereof;Fi'g. 2 is a faceelevation of said locking means illustrating the position the same assumes in connection with the fixed rim; Fig. 3 is a detailed face elevation of the locking head; Fig. 4 is a plan view of said locking head, and Fig. 5 is a detailed elevation of a modified form of-floating ring lockingmeans.

Similar numerals of reference indicate similar parts throughout the several views.

In the drawings (1) indicates a felly having rigidly mounted thereon a fixedrim (2) having formed therein at its front edge an annular groove (3) and at its rear edge a compound retaining wall (4) (5) indicates the base member of a demountable rim provided at its rear edge with a reinforcing flange (G) engaging retaining wall (4:) on fixed rim (2.) and said demountable rim (5) havingformed thereon adjacent to-said reinforcing flange (6) a supporting or retaining shoulder (7) adapt-- ed to receive a supporting tire'retainmg ring Said rim (5) has formed therein at its forward edge a depending channel (9) 1 provided with a lower engaglng locking surface (10) resting on the edge of rim (2) ata point where said rim (2) depends lnto groove and immediately ad acent to said depending channel (9.) an upwardly progect-lng' annular r1b.(1.1) and at the'extreme outer edge of said rim an overlapping flangeor housing (12). Said up wardlv pro cct1ng annular rib (11) receives one of said flanges (11) being-adapted to said flanges being adapted to engage the upper outer surface of the overlapping flange or housing (12) of rim (5). This only strengthening the supporting facilities of the separable tire ring (13), but further insures the supporting facilities ofthe rib (14) as well as the outer body of rim (5) in its entirety.

separable ring (13) is split and at such split ends a spring pin (15) is inserted through suitable apertures therein engaging a corresponding aperture in rib (11.) for holding the same permanently into place on the base member (5) of the demount'able rim. Fixed rim (2) has formed therein an aperture adapted to receive the depending end (17) of lug (18) which is spot welded .on the under surface of the base member (5) of the demountable rim, the object of which is to prevent the circumferential creeping of the demountable rim structure as a whole.

and free to move annularly with relation thereto a floating-ring (19) provided with free ends having cut therein a slot (20) adapted to receive one end of levers (21) 'which are pivotally mounted therein the other ends of saidlevers (21) being pivot; ally mounted as at (22) in the flanges of locking head (24;).

The locking head (21) has formed therewith a laterally projecting supporting body (25) having cut therein an aperture (26) adapted to receive a locking sleeve (27) provided with a hexagonal head (28) said sleeve being internally threaded to engage the threaded supporting stud (29) the upper end of said stud being flattened out as in (30) and spot welded to the inside surface said threaded stud becomes a rigidly supporting means as associated withthe fixed rim.

The base wall of groove (3) has cut thereseparable tire retaining ring which is. provided with two depending flanges (11-);

projectinto channel (9) and the other of type of structure provides a means of not- Annular groove (3) has mounted therein of the wall of groove at which point in apertures th ugh which the flanges o aft sub-seal the inside engaging surfaces of both the fixed run and demountable run, as well as-the looking meanstherefor,

With reference to Fig of t is drawings the float-ing'ring (19} has formed on its re spective ends thereot depending lugs (32) having mountedin their lower ends thereof levers"'(33 pivotally mounted together at their ends (3 i),'one of said lugs (32) havingpivotally mounted herein a earn lock (35) at (36). flSaid cam lock (35) has formed,

therein an aperture (87) adapted to receive the'endof a suitabletooliorexpanding and contracting the floating ring (19) with r'elation to; ,fix'ed rim anddemountable rim.

' It is o vious that the devices herein shown and de'soribed may be widely varied without departing from the spirit of the invention, i

What we claim and desire to secure by Letters Patent of the United States is 1. A devicebf the character described comprising a fixed rim having formed thereinat one-edge an annular groove and at its opposite edge a retaining reception shoulder, a floating ring mounted in said annular groove and freeto move circlnnferentially with relationther'et links mounted in the ends of said floating ring, a supporting stud rigidly mounted on the outer surface of groove "of said fixed-rim, a locking sleeve movable on said stud, a locking head carried by said locking sleeve provided with flanges adapted to project into said annular groove having associated therewith means for reeeiving the opposite ends of said links carrierl'hy said floating ring.

2. A- device ofvthe character described noes m1 comprising a fixed annular rim provided at ried by said locking sleeve provided with upwardly'projecting flanges provided with means adapted to receive the opposite ends of said links carried by said floating ring,

said locking head being adapted to cover the apertures of said fixed rim when in its locked position.-

3. A device of the character described including a locking means for demountable rims comprising a supporting stud rigidly mounted on the outer surface of a fixed rim, a locking sleeve movable vertically on said supporting stud,-a locking head carried by said locking sleeve movable vertically therewith having formed thereon vertically projecting flanges, a floating ring mounted in said fixed rim and free to move circumferentially a limited distance with relation thereto and provided with free ends, links pivotally mounted in the free ends of said ring, the opposite ends of said links being 'pivotally mounted in said vertically projecting flanges on said locking head.

In testimony whereof we have hereto signed our names in the presence of two subscribing witnesses.
