RESILIENT TIRE.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed July 1, 1912. Serial No. 706,958.

ing a pneumatic inner tube, which is adapt-' ed to be inserted within the common type of outer casing.

Another object of-this invention is to construct an inner pneumatic tube which is spaced a art from an armor casing and is connecte therewith by means of spokes.

A further object of this invent-ion is to construct a combined armored and pneumatic tire wherein the armored portion of the tire is spaced apart from the pneumatic portion thus absolutely preventing any possibility of puncture to the pneumatic part of thetire.

A still further object of this invention is to construct a com ound member adapted to be fitted within tlEe ordinary outer casing, which member is constructed of an outer armor casing and an inner pneumatic tube spaced apart from the armor casing in relation to the tread portion of the tire.

Still other and further objects of this invention will in part be obvious and will in part be pointed out in the specification hereinafter, by referring to the drawings in which like parts are designated by like numerals throughout the several figures.

Figure 1 is a cross sectional view of the device in position in the ordinary outer casing on a wheel rim. Fig. 2 is a longitudinal detail sectional elevation of a portion of the device. Fig. 3 is a plan view detail of one of the inner segments. Fig. 4 is a sectional view taken on line 4-4 looking in the direction of the arrow on Fig. 3 with the spokes in position.

' It is old in the art of armored tires to arrange an armored casing between the outer tube and inner tube wherein the inner tube 5 is in direct contact with the entire surface of the armored casing. It is alsowell known 1n the armored tire art to arrange metallic plates or other armored construction'in the body of the outer tube. Both of these types of armored tires are objectionable for the reason that the continued shocks upon the outer tube have a tendency to displace or break down the intimate relation of the outer tube to the armored feature, and it is also difiicult to obtain an armor which is sufficiently resilient, at the same time absolutely non-puncturable. The present invention seeks to overcome the difliculties of the type of devices hereinbefore recited, by armoring a casing adapted to fit into the outer tube and spacing this armor apart from the pneumatic tube in such manner that it becomes substantially impossible to puncture the inner tube.

Referring now to the drawings and more particularly to Fig. 1, my improved construction comprises an armored casing 1,

which is composed preferably of layers.

The first layer 2 is preferably of heavy canvas, the second layer 4 of elastic rubber, the third layer 5 of heavy canvas, and the fourth or inner layer 6 preferably of heavy segments composed of fiber, that is wood fiber or pulp fiber, arranged in semi-circular sections, and this inner layer is adapted to carry a series of sockets 7 which are attached thereto by means of rivets or any convenient attaching device. The several layers of the armored casing l are cemented together by means of rubber cement or any suitable cementing material. Spokes 8, preferably wood, are fixedly mounted by means of rivets to the segmental fiber or fibroid segments 9 which rest immediately over the inner tube 10. ments 9 are inclined in such manner as to overlap, as is more clearly shown in Fig. 2.

The spokes 8 pass through openings 1n a 'fibroidtubular casing 11. It will be noted that the spokes 8 are fixedly attached to the segments 9 and are slidable in the sockets 7. The fibroid tubular casing. 11 is provided with an annular open space upon its interior periphery, and carries flaps of canvas 12 which-are adapted to cover this opening. The flaps of canvas are attached to the fibroid tubular casing 11 by means of eyelets 14 which perform the double function of securing the canvas flaps to the fibroid casing and of providing eyelets for the lacing string 15 which prevents the tubular casin from spreading when the inner tube is in ated with pressure sufiicient to carry the The ends of the segweight upon the tire. The casing 1 is adapted to fit within the ordinary outer casing 16, which is commonly used in connection with pneumatic tires. I desire it to be understood that the casing 1 is a separate'entity from the outer casing 16. I also desire it to be understood that the casing 1 comprises a container which carries all of the interior construction, including the spokes 8, the fibroid tubular casing 11, the inner tube, etc., and comprises a device which is intended to supplant the large inner tube which is commonly used in 006peration with the ordinary outer casing in the common well known construction of pneumatic tires.

In the device herein described, it will be noted that the inner tube 10, which comprises the container for the compressed air, is spaced a considerable distance from the outer casing, as is shown in Fig. 1, and it will also be noted that the casing 1 is of such a construction as will be very difficult to: puncture, and even though it were punctured, there is little danger of the puncturing element reaching to the inner tube 10. The outercasing, it will be noted when in service, will be compressed in such manner that a cross section will be elliptical with the major axis of the ellipse at right angles to the middle plane of the wheel. The casing 1 may be laced together on its inner periphery similar to the lacing of the fibroid casing, but i have shown my device preferably with the casing 1 sup ported entirely by means of the outer casing or tire 16.

The outer casing 1 is clamped upon an ordinary wheel rim 1? by means of retaining rings 18', in a manner well known in the art.

Having thus described my invention what I desire to claim is 1. In a device of the class described in combination, an armored casing, an armor tube within said casin inner tube within said armor tube, segments between a portion of said inner tube and said armor tube, spokes fixedly attached to said segments and extending through openings in said armor tube, and socket members carried by said armored casing and adapted to have slidable engagement with said spokes.

2. In a device of the class described in combination, an armored casing comprising a layer of. canvas, a layer of rubber, a second layer of canvas and an inner layer of fiber; an armor tube composed of fiber, arubber inner tube within said armor tube, segment members between said inner tube and said armor tube, and spokes extending between said segments and said armoredcasing. i

3. In a device of the class described in combination, an armored casing, an armor tube of less diameter in cross sectional area than said armored casing, an inner tube' within said armor tube, said armor tube being provided with an opening, canvas flaps adapted to overlie said opening, eyelets in said armor tube, and lacing members adapted to pass through said eyelets and prevent said tube from expanding when the inner tube is inflated, segment members between said inner tube and said armor tube, and a series of spokes extending between said segment members and said armored casing.

l. in a device of the class described in combination, an outer casing, sockets carried by said outer casing, a pneumatic tube within said outer casing, the external diameter of said pneumatic tube being less than the internal diameter of said outer casing,

spokes cooperating with said sockets, and means cooperating with said spokes to trans. fer thrusts upon said spokes to said pneumatic tube.
