COUPLING MEANS FOR DEMOUNTABLE-RIM SECTIONS.

Specification of Letters Patent.

Patented Sept. 25, 191%.

Application filed November 29, 1916. Serial No. 134,053.

To all whom it may concern Be it known that I, FREDERICK B. CUM]?- STON, a citizen of the United States, and a resident of Blooming Grove, in the county of Navarro and State of Texas, have invented a certain new and useful Improvement in Coupling Means for Demountable- Rim Sections, of which. the following is a specification.

One of the principal objects of my present invention is to provide an improved coupling means for circumferentially. divided demountable rim sections, in the nature of a lockingplate slidably carried on the under side of one of the sections, and having hooks adapted, when the sections are put together, to overhang a portion of the opposite section, and, to be shifted for engagement with keeper lugs carried on the under side of the opposite section.

Another object of the invention is to provide an improved device of the class described, which will be extremely simple, durable, efficient in operation, and inexpensive to manufacture.

With these and other objects in View which will become apparent as the description proceeds, the invention resides in the construction, combination, and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawing in which like characters of reference indicate like parts throughout the several figures, of which Figure 1 represents a view in section taken radially through a rim constructed according to my invention; I

Fig. 2 represents a partial plan view showing the locking plate in position for cou pling the rim sections together, the view being taken looking toward the under side of the rim; 1

Fig. 3 represen s a view in perspective. showing the rim sections separated and illustrating the arrangement of the lugs carried by the rim sections;

Fig. 4 represents the locking plate;

Fig. 5 represents an enlarged sectional view, taken transversely on the plane indicated by the line 55 of Fig. 2.

Referring more particularly to the draw-- ing, a wheel felly is indicated at 5, and i ilas rim is divided circumferentially into a permanent section 6 which may be suitably sea view .in perspective of cured to the felly 5, and a removable sect on 7 whlch may be shifted laterally ofl of the felly and away from the section 6, in

a manner well known, when it is desired to remove the tire indicated at 8, or the inner tube thereof.

Secured on the under or inner face of the rim 7 along a line spaced from the inner edge 9 thereof, is a plurality of spaced lugs 10. These lugs are riveted or otherwise suitably secured to the section 7, as indicated in Fig. 5. The lugs 10 serve as guide means for a locking plate, indicated generally at 11, which plate is adapted to bridge the joint between the rim sections when the latter are placed together, and is adapted to be shifted longitudinally for engaging a plurality of spaced keeper lugs 12. welded or otherwise suitably secured on the under face of the rim section 6, with hook portions on said plate 11. a

The plate 11 is provided adjacent one 13 formed V edge with a series of alined longitudinally extending slots 14. corresponding in number to the lugs 10 and through which slots said lugs extend. The lugs are provided with beveled lateral edges 15, and the lateral edges of the slots 14: are likewise beveled so that the plate will thus be retained in disengagement from the rim section 7. The slots 14 are substantially twice the length of the lugs 10, whereby to allow a limited longitudinal movement of the plate 11 relatively to the rim section 7. I

The hook portions 13 of the plate are defined by a series of L-shaped slots 16 p ro-. vided in that portion of the plate which The lateral overhangs the rim section 6. reaches of the slots16extend clear to the edge of the plate, so that the keeper lugs 12 may be introduced into the slots 16 when the section 7 is being placed in position upon the fell it being understood that the laterally extending portionsof the slots 16 are spaced apart distances corresponding to the distances between the lugs 12. The keeper lugs 12 are beveled on all four edges, andall of the edges of the slots 16 are also beveled, so that the plate 11 will be held down against the under surface of the permanent rim section 6 at all times that-the lugs 12 are engaged within the slots 16.

It will be understood that. when the rim sections are to be connected together, the plate 11 will be shifted to assume the dotted line position indicated in Fig. 2, and the Itiihrsection'? will be so positioned with respect. to' the section 6 that the bevel edged tongue 17, provided on the rim section 7,

2e pered as shown, the recess 18 into which it extends beinglikewise tapered.

will be opposite the bevel edged recess 18 provided in a lug or thickened portion19 of the rim'section 6. The section 7 will then be moved against the section 6, so that the tongue 17 will enter the recess 18, and at the same time the lugs 12 will. enterinto the lateral portions of the slots 16. lVhen the sections are closed, the plate 11 will be shifted into the full line position indicated in ig. 2, thereby engaging the lug 12 in the longitudinally extending portions of slots 16,

and hence engaging the hook portions 13 of the plate over the lugs in such manner as to prevent lateral displacement of the sections 6 and 7 relatively to each other.

The tongue 17 extends laterally beyond the inner edge 9 of the section 7, and is ta- This tongue,

in engaging with the lug or thickened portion 19, prevents creeping movement of the rim sections relatively to each other, and hence will prevent any possibility of disengaging the hooks 13 and'lugs 12 through a creeping movement of the rim sections.

"A plurality of the locking devices 'is arranged at spaced intervals around the perimiter of the rim, and in order to accommodate the locking devices, the telly 5 is pr0- .Vided on its periphery with recesses 20 of suitable length to allow of the accommodw tion of the locking devices and to allow the plates 11 to be shifted into and out of lockmg position. The recesses 20 are of sufficient depth to conveniently accommodate the locking devices, and in order to close these recesses, the telly is provided with removable metallic lugs or blocks 21 removabl y thereof, as

naaneae may be inserted in the recesses 20, for shifting the plates 11.

Although I have described the preferred embodiment of my invention, I may desire to make such changes in the construction, combination, and arrangement of parts do not depart from the spirit of the invention and the scope of the appended claims. 7

1. The combination with a circumferentially divided rim, of a plurality of bevel edged guide lugs carried on the under side of one of the rim sections, a securing de-- vice for the rim sections comprising a plate having bevel edged. guide slots engaging the said guide lugs, said slots being of a length greater than the length of the guide lugs, said plate adapted when the sections are placed together to overlie the opposite rim section on th'e under side thereof, a plurality of bevel edged keeper lugs carried by said opposite rim section on its under side, said plate being provided'with bevel edged angular slotsadapted to be engaged over the keeper lugs whereby to couple the rim sections together, and enacting means between the rim sections for guiding them together and for preventing creeping movement of the sections relatively to each other.

2. The combination with a circumferentially divided rim, of a securing device for the rim sections comprising a plate adapted to bridge the jpint between the rim sections when the latter are placed together, cooperating guide means between the plate and one of the rim sections for normally supporting the plate on said section and allowing longitudinal shifting movement of the plate, a plurality of keeper lugs carried by the opposite rim section, a plurality of hook portions formed on the plate and adapted when the latter is moved in one d1- rcction to engage over the keeper lugs for preventing separation of the rim sections, and coiiperating guide means between the rim sections for properly guiding them together and for preventing creeping movement of one rim section relatively to the other.
