ALBERT E. GRAY, OF GOODLAND, INDIANA.

S-RI'M FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Sept. 18, rare.

Application filed September 1, 1916. Serial No. 118,097.

To all whom it may concern:

Be it known that I, ALBERT E. GRAY, a citizen of the United States, and resident of Goodland, in the county of Newton and State of Indiana. have invented certain new and useful Improvements in Sand-Rims for Automobiles, of which the following is a specification.

The present invention relates to vehicle wheels and has particular reference to new and useful improvements in demountable supplemental rims ortreads for use in connection with a vehicle wheel, the primary object being to provide a simple and improved rim or tread for permanent or detachable association with motor vehicle wheels to afl'ord additional tread surface therefor when in use insoggy or sandy earth.

It is well known to those skilled in the art that when heavy loads must be transported over bad roads and through plowed fields or over soft earth the heavy motor trucks now in use encounter their greatest obstacle, the ordinary wheels becoming embedded in the earth. This is particularly true when used in cross country work or in military use.

My invention contemplates the provision of demountable rims which may be quickly and easily attached to the existing types of motor vehicle wheels, whereby to provide a greater tread surface and consequently reduce the liability of the wheels becoming mired.

A further object of my invention is to provide demountable rims which may be associated with the various types of motor vehicle wheels now in use, various modifications of my improved rim serving to adapt the same to various types of wheels now in use.

A further object of my invention is to provide a rim of the class referred to which is simple in construction, strong and durable, cheap to manufacture and economic in use.

Other objects and advantages to be derived from the use of my improved demountable extension tread will appear from the following detail description and the claims, taken with an inspection of the accompanying drawings, in which Figure 1 is a fragmental side elevational view of a vehicle wheel show ng the preferred form of my improved extension rim applied thereto;

Fig. 2 is a vertical sectional view of the same;

Fig. 3 is a View similar to Fig. 1 of the modified form of my invention;

Fig. 1 is a transverse sectional view of the same;

Fig. 5 is a view similar to Fig. 3 showing a still further modified form of my invention;

Fig. 6 is a transverse sectional view of the same; and

Figs. 7, 8, 9, 10, 11. 12, 13, 14 and 15 are transverse sectional views of various modifications of the extension rim shown in Figs. 1 to 6.

Referring more particularly to the drawings and specifically to Figs. 1 and 2,wherein similar characters of reference designate like and corresponding parts, 1 designates the felly of the wheel, 2 the spokes and 3 the rim. The usual tire 1 is carried by the rim 3. Of course,any approved type of heavy duty tire may be associated with the rim, the form shown being only one illustration of the same.

In the form of my invention shown in Figs. 1' and 2 a pair of rings 5 and 6 are provided, said rings having a plurality of rightangular bracket members 7 and 8 carried by the inner peripheral surfaces thereof, bolts 9 serving to hold the brackets rigidly to the rim. The brackets extend beyond the inner periphery of the folly 1 and are provided with apertures through which one of a plurality of bolts 10 is adapted to pass, the bolts 10 having locking nuts 11 on the free ends thereof. Spring locking washers 12 are inserted between the heads of the bolts and the brackets and between the nuts and the brackets. Upon reference to Fig. 1 it will be noted that the rims 5 and 6 are divided as at 13, the bracket at this point being slightly wider than the other brackets to receive a plurality of bolts 14: to engage both of the abutting ends of the rim.

Referring to the modified form of my invention illustrated in Figs. 3 and 4: the usual felly 15 is shown correspr ding to the felly 1 illustrated in Figs. 1 and 2. The usual rim and tire are mounted upon the felly 15. In this form of my invention the extension treads are designated 16 and 17 and are right-angular in cross section to through which bolts 25 pass, said bolts engaging rings 26 and 27, said rings being right-angular in cross section and carrying the tread rings 28 and 29, being riveted thereto as at 30. The demountable tire carrying rim is designated 31 and is mounted outside of the tread rings 28 and 29 as best shown in Fig. 6. I

In the drawings the tread rings have been shown of equal widths, but, of course, it Will be understood that the inner tread rings, that is, the ring adjacent the body of the vehicle must necessarily be slightly narrower than the outside ring. However, this does not materially affect the operation of the device.

Referring specifically to Fig. 7 the felly is designated 33 and is provided with a plurality of transverse openings 34. A demountable rim 35 is provided, said rim carrying a tire 36. A wedge ring 37 is interposed between the outer periphery of the felly and the inner periphery of said rim 35. The tread rims are designated 38 and 39, the same being provided with annular flanges 40 and 41 through which the free ends of the bolt 42 pass, said bolt being arranged in one of the said openings 34. Of course, it is to beunderstood that there are a plurality of bolts arranged around the felly of the wheel. As indicated at 43 the corners of the tread rims 38 and 39 engage under the rim 35 and serve to retain the same in position on the felly.

Referring to Fig. 8 I provide a felly 44, the same being relatively wider than the ordinary felly and provided with a wear or "tread plate 45 of an equal width. The tire carrying rim is designated 46, no tire being shown therein. An interior plate 47 is provided, said plate having a plurality of bolts 48 extending radially therefrom, the free ends of said bolts being riveted at 49'to the wear plate 45. A pair of retainin rings right-angular in cross section and designated 50 and 51 are provided, a plurality of bolts, only one of which is shown and designated 52 passing through said retaining members.

It will be noted that by providing a wider felly and placing a tread plate thereon very good results may be obtained by either permitting the tire to remain on the rim or removing the same.

Referring specifically to Fig. 9 the felly is designated 53 and is provided with a protecting plate 54. The tire carrying rim 55 is provided, the same being formed with lateral annular extensions 56 and 57 performing the function similar to the tread rings hereinbefore referred to.

Referring to Fig. 10 it will be noted that this form is a slight modification of the form shown in Fig. 8, an elongated felly 58 being provided on which the tire rim 59 is mounted carrying the tire 60. A wear or tread plate 61 is provided on the felly 58 for an obvious purpose.

Referring to Fig. 11 I provide a relatively wide felly 62 provided with a wear plate 63. The tire carrying rim 64 is mounted on the plate 63, said tire carrying rim being slightly narrower than the felly. A pair of tread rings 65 are mounted adjacent the free marginal edges of the felly 62, a plurality of bolts 66 extending through the felly and said rings to retain the latter in opposite position.

In Fig. 12 I have shown a felly 67 provided with a wear plate 68 and a tire carry= ing rim 69. The felly 67 is provided with a plurality of transverse openings 70 to re,- ceive retaining bolts 71, said bolts extending through one side of a pair of channel- irons 72 and 73, said channel-irons forming the extension tread surface.

Referring specifically to Fig. 13 the felly 74 is shown provided with a plurality of transverse openings 75. The tire carrying rim and tire are shown and designated 76 and 77, respectively.

A pair of tread rings 78 and 79 are provided having. brackets 80 and 81 riveted to the under sides thereof. Ring members 82 and 83 are interposed between the brackets and the sides of the felly to engage the rim 76 and retain the same on said felly. A bolt 84 extends through the opening and engages with the brackets and 81. It Will be noted that in this form of my invention the tread members serve a double function, that is, act to prevent sinking of the tire and also to retain the demountable rim on the felly.

Referring to Fig. 14 I haveshown a further modified form of my invention for use in connection with heavy duty trucks, wherein more than one tire tread surface is employed. In this figure I have illustrated a felly 85 having a tire rim 86 thereon in which are mounted a pair of tires 87. The tread rings are formed preferably of pressed steel having tread surfaces 88, bracing portions 89 and flange portions 90, one of a plurality of bolts being shown and designated 91, said bolts passing through. the flange portions 90 for retaining the said rings in position on the felly.

Referring to Fig. 15 I have presided a Wheel having the tread surfaces associated therewith, the wheel being cast entirely in tegral. The felly of the wheel has been designated 92, the body portion 93 and the tire $1111 94 on which ma be mounted atire 95. A pair of annular rlngs 96 and 97 are cast integrally with the felly 92 and extend therefrom acting as additional tread surfaces. It is not thought that any lengthy discussion of the uses of my improved demounta'ble tread is at this time necessary, in view of the fact that the operation of the same is self-evident. However, I desire to direct articular attention to the extreme simplic- 1ty of all of the forms of the invention, but few of the same requiring any modification of the wheel to facilitate application of the demountable tread. -The forms of my invention shown in Figs. 1 to 6 are preferred, particularl in view of the fact that the same may e adapted to any of the existing types of automobile wheels without materiall alterin the structure of the wheel. Slig t alterations in the structure of a wheel felly would be necessary in the structure shown in Figs. 7, 12, 13 and 14. In the remaining views the structures require difi'erent types of wheel fellies which necessarily means a change in structure. However, all of the structures embody the same principle, and it will be noted that when in normal use the flanges forming the tread rings do not interfere in any manner with the running or" the vehicle.

The form of felly shown in Fig. '10 is particularly adapted for use in connection with light trucks and the like. Thus it will be seen that regardless of the type of truck or the load my improved demountable auxiliary tread may be readily associated with the driving and steering wheels.

From the above description taken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, operation and advantages of my invention may be had, and while I have shown and described the device as embodying a specific structure, I desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination wlth a felly, having a double tire rim thereon, of a pair of annular flange members having tread surfaces and bracing portions, said members being adapted to abut said felly, said members being provided with annular flanges, and a plurality of bolts extending through'said flanges and engaging the inner peripheral face of the felly to maintain said members in abutting relation with the felly.

2, The combination with a felly, of a pair of tread rings, a portion of said rings adapted to abut the side of said felly, lateral extensions extending from the upper edge of the felly engaging portions providing tread surfaces, bracing portions connecting the free ends of the lateral extension and the felly engaging portions, the bracing portions adjacent the felly engaging portions being flattened to form annular flanges, and a plurality of bolts extending through said flanges and engaging the inner dperipheral face of the fell-y to maintain sai members in rigid position for a purpose specified.

In testimony whereof, I afix my signature hereto.

ALBERT E. GRAY.
