GEORGE E. WHITESIDE, OF EAST POINT, GEORGIA.
DEMOUNTAIBLE RIM.
Specification of Letters Patent.
Patented Jan. 3, 1922.
Application filed July 23, 1920. Serial No. 398,599.
To all whom it may concern:
Be it known that I, GEORGE E. WHITESIDE, a citizen of the United States, residing at East Point, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Demountable Rims, of which the following is a specification, reference being had'therein to the accompanying drawing.
This invention comprises a demountable rim. 'VVhile its application is unrestricted, it is-especially adapted for use in connection with the wheels and tires of motor and the like vehicles.
It is contemplated among the objects of the invention to provide a rim of this character which will be standard in the sense that it may be used with and fit any of the felloes or wheels at present in extensive use without notching or otherwise changing their construction in order to conform to the rim.
Other objects within the scope of the invention are to provide a rim made in several sections and interconnected so that it may be readily collapsed and assembled; quickly-applied to tire casings without the aid of special tools or the aid of skilled labor; which will have a minimum number of parts dea signed to be constructed and assembled in accordance with the most approved manufacturing methods, and which will, in a word, comprise a simple and practical device for these purposes.
Still other objects are to produce an improved form of interlocking between the edges of the rim'at the point of fastening whereby any movement in either an axial or radial direction is prevented when the parts are locked, and wherein a lockino; device is provided with means for'positively positioning the ends of the sections when looking and positively moving one out of alignment with the other when unlocking both movements being accomplished without the aid of additional tools.
Other objects and advantages will in part be apparent and in part be brought out more fully inthe description which follows.
A. drawing illustrating an embodiment of the invention is hereto appended, the followin views being shown':
Tig. 1 is a view in side elevation of the device in assembled position, portions being shown in section;
Fig. 2 is a view in perspective showing in detail a form of locking device;
Fig. 3 is a view in longitudinal section through a portion of the device; and
Fig. 4 is a view in bottom plan of a fragmentary detail illustrating a locked arrangement of the meeting ends of the sections.
In these views, 1, 2 and 3 designate sectionspf a demountable rim of the usual channel-shaped variety. Section 2 is, at its opposite extremities, connected to sections 1 and 8, respectively. The means here shown comprise a knuckle 4:, formed by folding back a flap formed on the end of one of the sections and spot welding it to the portion of the section with which it contacts. Two flaps are generally similarly, formed on the part which is to be connected, so that when assembled there will be an eye extending through the aligned flaps and within which a pin or the like 5 may be inserted. This constitutes a hinge joint between the sections, the portions of which are formed directly by stamping and bending a portion of the sections themselves, and the folding back of the flaps and Spot welding them to form the hinges eliminates the use of rivets, or
other securing means, and insures a composite structure 7 with no additional parts to become loose and rattle.
The other ends of sections 1 and 3 are adapted to be secured together in a. manner which will insure against displacement in a radial or axial direction and prevent circumferential expansion. To this end,-the underneath portion of the channel sections is provided with corrugations or notches 6 (Fig. 4:) which are preferably in the form of. projections on one part and corresponding depressions in the coacting part. The arrangement here shown comprises projections on the end of section 1 coacting with corresponding depressions in the end of section 3. lVhen assembled as shown in Fig. 4, the parts will be locked against movement in an axial direction or from side to side on a wheelfelloe.
Means are also provided for positively locking the ends of connected sections 1 and 3 against radial movement when they are 1n locked position; and as here shown, such means comprise corrugations or notches? on v the sides of the sections. These, as just described, also have the form of lugs or projections on one section coacting with and fitting into correspondingly shaped depression on the other section, so that when assembled, as shown in Fig. 1, they will be prevented from relative movement in a radial direction.
A combined locking instrumentallty and section-separating means is associated With' the free or outer ends of sections 1 and 3, just described, and, as here shown, include an actuating lever 8'pivotally secured at one end to the end of one of the sections. The manner of connecting is by means of a pin 9 which passes through an opening 10 in the end of the lever and through eyes formed on a knuckle 11 on the end of the section to which it issecured.
In connection with this line there is provided a means of first imparting to the abutting ends of the section when assembled a circumferential movement to disengage the corrugated portions 7 of the sections. This is done at the initial movement of the lever, and, as here shown, is effected by means of a cam 12 having a notch 13 cut across its face, leaving ribs or projections 14: and 15 along the face thereof, one of which, 14, normally engages an end portion of one of the sections when closed. Movement of the lever to the position shown in F ig. 3 forces the ends of the sections apart and initiates a relative movement of the sections radially. This radial movement is started by projection 14 and completed by the other projection 15 on the. cam, the latter being adapted to engage the inner ortion of the section against which it is earing and positively move it out of alignment with the end of the next abutting section. When the end has passed out of alignment the entire sections 1 and 3 may be swung on their pivots inwardly for dismounting. To facilitate the initial movement of the lever, it-is provided at'its opposite end with under-cut portions 16 for the insertion of a wedge as the pressure of projection 14 against the end of section 1 normally'holds the lever flat against the under side of the-rim. A pin 17 is also provided in the outer end of lever 8 and fits in an opening in the rim when the lever is in closed position. This locks the sections against circumferential movement.
To give an initial spreading movement to the ends of sections 1 and 3 when assembling, lever 8 is provided at a point near itspivotal connection to the end of section 2 with a notch 18. This notch engages the end edge of section 1 before it comes in contact with projection 14 on cam 12 and initiates the spreading of the sections. Continued movement of lever 8 to open position forces the end out of the notch and into contact with projection 14in the cam face.
The hinges and lever are of approximately equal thickness and. constitute bearing points for the rim or the felloe. The rim is also provided with a valve guide and retainer 19, here shown punch drawn from circumferential movement between the felloe' and the rim.
What I claim is:
1. A demountable rim comprising a plurality of sections connected together for swinging movement inwardly; and means for locking the sections in assembled position as acomplete rim, said means including a lever pivotally mounted on an end portion of one of the sections, and a cam portion in th lever, said cam bein provided with a notch adapted to receive an end portion of a section when in locked position.
