Application filed May-'1, 1916. Serial No. 95,471;

Be it known ,that I, Anonna H. HARRIS, a citizen of the United States, residing. at Barberton, in the 1 county of. Summit and State of Ohio, :have invented certain new and useful Improvements, inDemountable Rims, of which-the following is a specifi cation.

In the modern ,tor'm ot demountable rim which is extensively used, wedge lugs or. wedge rings are forced between the telly band and the .rim baseand-thus hold and This method of mounting the rim has provenunsatisfactory for several: reasons, and it; is the p'ur'w pose of my invention tocorrect and obv ate theseevils. y l

' The wedge rings orwedge cla mounting a rim on a telly band, a ter a considerable use, will become stuck to the telly band and rim by rust and mud, making it quite difficult to "remove themtinthe operation of demounting thelrim; Furthenthe rims are apt to squeak particularly when held on by wedge clamps and not a continuous ring. In the construction. herein 'shown, each objection has been obviated.

The drawings accompanying this specification and forming a part hereof in which like reference numerals refer to like parts:

Figure 1, is a cross section of a rim mount: ed in place by my improved clamping ring.

Fig. 2, is a front vietv of the clamping mechanism removed from the rim.

Fig. 3, is a fragmentary perspective view of a telly and telly band showing one of the seats for the clamp.

The construction invented by me comprises a toggle clamp which may be forced in by a nut on a lateral bolt, and upon being forced in exerts a considerable pressure tending to force the rim to its final position on the telly band.

In the drawings 1 represents the ordinary wood telly of the wheel and 2 the telly band shrunk or secured in any suitable manner to the outer face of the telly. The telly band comprises a flat portion indicated at 3 and an inclined surface or ledge 4: which is arranged at'the rear-of the wheel with reference to its position on an automobile. A suitable number of transverse bolts 5 are passed through the telly, the heads of the bolts 6 resting against plates 7 at the rear of the telly. A. flange 8 may be formed on mps used in i the upper part of plate 7 and serves to back up the telly band 2. j

The front edge of the telly band 2 may be beveled off at a number of places as shown at 9, the beveled portions corresponding in .number and being located over the transverse bolts. To the inclined face 9 in the form shown in the drawings may be attached the under inclined face of a tapering projection 10 formed on a plate 11, the main portion of which is seated against the front If desired, the plate 11 may be formed integral with the telly band3 either as a continuous flange or as a series of plates, and carries an integral boss or projection 11 received in a socket in the telly and provided with an integral screw threaded bore which is adapted to be mated with the screw threads on the bolt. By this construction the bolt 6 serves as an additional means for holding in andsupporting the plate 11. l

The rim or rim base13-is formed with a continuous projection {or head 14 on its under surface, the under side of the bead being tapered to correspond to the inclined face 4 of the telly band, the purpose of this construction being to allow the back of the rim 2. wide bearing space on the telly band. In the front of the rim approximately above the front: end of the telly is formed on the under side of the rim a second rib or bead 15. Where the rib or bead-rises from the rim base, there is formed a curved socket or fulcrum 16, the purpose of which will presently appear.

The rim shown in the drawings is formed with a gutter 17 at its front side, which is adapted to take a locking ring to hold a removable flange, the type of rim being commonlyknown as a Q. 1). rim. This construction is not essential, however, and the rim can be made as a plain clencher or a straight side if desired.

The rim and telly having been described, I will point out the novel and effective means which I use to center the rim to the wheel. This comprises what -might be termed a toggle clamp, which is formed of two members 18 and 19 joined in hinge relation by a pintle 20 being passed through the center of the knuckles 21 and 22 formed side of thetelly. At its lower end, the part a I V integral with the parts 18 and 19 respectively. The lower end of the member 18 bearing portion 25, in the center of which is formed cally.

The operation of the device will be clear from the foregoing description. In mounting the rim, it is passed over the felly until the bead 14 contacts with the inclined surface 4: of the felly band. The toggle members 18 and 19 which are drawn by the pintle 20 to form a complete clamping unit are then set in position with the portion 23 in the socket or fulcrum 12 and the portion 24 in the fulcrum 16, the slot 26 being passed over the projected end of a bolt 6. The

a slot 26 slightly elongated vertinut 27 is now threaded on the projecting end of the bolt and each nut about the wheel is tightened equally. By this means the pressure tending to straighten the toggle will exert a positivecentering and tightening action on the rim base.

It is obvious that various'modifications and changes may be. made in the device shown without departing from the spirit of the invention. The specific form of the toggle may be changed and the points to which'the power is applied may be altered operating transversely of. the wheel and means for operating the toggle to center i and hold the rim on the wheel.

2. The combination of a rim and a wheel structure, a rim securing means comprising a fulcrum on said wheel, a felly band adapted to form a seat for said rim, a toggle lever contacting said wheel structure at said fulcrum only, and means for operating the lever to force the rim to its seat.

3. The combination of a rim, and a wheel provided with a seat for one side of said rim, of a rim securing means comprising a fulcrum at the side of said wheel opposite said seat, a second fulcrum on said rim, a toggle spanning said fulcrums, and means to straighten the toggle to force the rim to its seat.

4. The combination of a rim, and a wheel provided with a seat for one side of said rim, of a rim securing means comprising a fulcrum at the side of said wheel opposite said seat, a second fulcrum on said rim, a toggle spanning said fulcrums, one of the members of said toggle being provided with a slot, a transverse bolt passed through said wheel and said slot, and a nut on said bolt bearing against said member.
