TEE-FASTENING DEVICE.

Application filed September 15, .1911. Serial No. 649,515.

To all whom it may concern:

Be it known that I, Ronmir CARR WALL, of Philadelphia, in the Stem of Pennsyl- Vania, have inventeda certain new and useful Improvement in Tire-Fastening Devices, whereof the following is a specification, reference being had to the accompanying drawm IVIy invention relates to means for fastening pneumatic tires upon vehicle wheel rims and particularly to a divided retaining ring flange and means for securing it upon a wheel rim,

' As hereinafter described, my invention includes a divided ring flange having inwardly projecting wedges at its ends, and wrench holds at its inner circumference near said ends, fitted to a rim having a slot to receive said wedges and fulcrum sockets affording access to said wrench holds; a lever wrench adapted to fit in said fulcrum sockets in engagement with said wrench holds, whereby said ring may be constricted upon said rim; and, means normally retaining said ring on said rim.

My invention includes the variousnovel features of construction and arrangement hereinafter more definitely specified.

In the drawing :Figure I is a side elevation of a wheel folly, rim and retaining ring conveniently embodying my improvement. Fig. II is a sectional view taken on the line II, II, in Fig. I. Fig. III is afragmentary side elevation of a wheel rim and retaining ring embodying a modified form of my invention. Fig. IV is a sec tional view taken on the line IV, IV in Fig. III.

In the form of my invention shown in Figs. I and II; the metal rim 1' is fitted in concentric relation upon the wooden felly 2 to which it is conveniently secured by the screws 3. Said rim is provided with the removable ring flange 5 which is divided as indicated at 6 in Fig. I and has inwardly projecting wedges 7 at its ends extending in a plane transversely to its axis, with complementary recesses 8 in the contiguous edges of saidwedges; wrench holds 10, adjoining said ends, and conveniently oppositely inclined ratchets atthe inner circumference of said ring. Said ring has the stud 11 rojecting radially inward @intermediate of its ends 11 fitted to the socket 12 in said rim 1, the latter havirw a slot 14 to receive said wedges 7, and fa cram sockets 15 afi'ording access to said ratchets 10. The screw 17 which extends in said recesses 8 norinallyretains said ring on said rim by engagement with said telly as indicated in Fig. II. Upon removing said screw 17 the ring 5 may be detached from the rim 1 by springing its ends outwardly with the lever 18 which may be conveniently engaged in the notches 20 in said rim. To replace said ring its stud 11 may be engaged with the socket 1.2 in said rim 1 and its ends sprung apart, with the wedges 7 in alinementwith said slot 14. Thereupon, the ring ends may be alternately shifted circumferentially to constrict said ring 5 upon the rim 1 and seat said wedges in said slot, by engagement of said lever 18 with the ratchets 10 through the fulcrum sockets 15. Itmay be observed that when the ends of said ring 5 are shifted circumferentially as above described and the wedges 7 pressed radially inward to the position shown in Fig. I, said wedges respectively bear upon the opposite ends of said slot 14 in the rim and thus prevent retraction of the ring from its constricted positionto which it has been shifted by the lever 18; the angle of said wedges in contact with said rim being such that it is necessary to move them radially outward to release them. However, the screw 17 prevents their accidental displacement.

In the form of my invention shown in Figs. III and IV, the metal rim 21 is provided with the removable ring flange 22'- which is divided as indicated at 23 in Fig. III and has inwardly projecting wedges 25 at its ends extending in a plane transversely to its axis, with complementary recesses or openings 26 in alineinent in said wedges; the latter being fitted in the slot 27 in said rim 21 so as to present said openings within the latter as indicated in Fig. IV. Said ring 22 is normally retained on said rim by the cotter pin 28, one limb of which extends through said openings 26; the opposite end of said pin being bent as indicated at 30, forming a spring catch to engage the edge of the contiguous wedge 25 and prevent ,accidental removal of said cotter pin. Said rim 21 is not provided with notches to receive the lever 18 like the notches 20 shown inFig. I; but, said ring 22 is provided with notches 31 to engage said lever'whereby its ends may be sprung outwardly to remove it from said rim 21. Said ring 22 is also conveniently provided with wrench holds 32 similar to'the wrench holds 10 in. the ring 5, and, like the latter accessible for engagement with the lever .18 throu 'h fulcrum sockets 33 in said rim 21. Sai' ring 22 is also conveniently provided with the stud 3i projecting radially inward intermediate of its ends and fitted to the socket 35 in said clai 1. A tire fastening device including a divided ring flange having inwardly projec ing wedges at its ends extending in a plane transversely to its axis, with complementary openings in the contiguous edges of said wedges, oppositely inclined ratchets at the inner circumference of said ring adjoining its ends, and a stud on said ring projecting radially inward intermediate of its ends; a rim having a slot to receive said wedges, a socket for said. stud, and fulcrum sockets affording access to said ratchets; a folly in concentric relation with said rim within the latter; and,a cotter pin extending in said complementary openings, normally retaining said ring on said rim; said pin having means to resiliently engage said ring includ ing an inwardly turned end overlapping the contiguous wedge.
