Abstract
ABSTRACT OF THE DISCLOSURE
Stiff inner tubes of the type normally used on military vehicles which are designed to run "flat" are inserted into tires using a bulky apparatus in a vehicle maintenance building. The standard tire changer already mounted on a truck or other military vehicle can readily be modified to include an inner tube insertion apparatus. The tire changer includes a base, a frame at one end of the base, a vertically movable carriage on the frame for holding the tire in a vertical position, and a horizontally slidable carriage mounted on tracks on the base for movement towards and away from the frame. The insertion apparatus includes a slide on an inclined ramp for carrying the inner tube into the tire, and a force transfer arm connecting the horizontal carriage to the slide so that movement of the horizontal carriage toward the frame is accompanied by forcing of the tube into the tire.

Description
~223~15 This invention relates to an apparatus for inserting an inner tube into a tire, and in particular to an inner tube insertion apparatus for tires of the type designed for use when flat.
In this case, the word "tire" is intended to mean the carcass or casing which normally covers an inner tube. Vehicles of the type employed by our armed forces are equipped with wheel assemblies, which are designed to run flat, i.e. even when the air pressure drops in the tires. The inner tubes used in such tires are relatively thick and stiff, and consequently difficult to insert into the tires. The assembly presently used to place an inner tube in a tire is large, expensive and not capable of use on a conventional vehicle. Thus, a need exists for an inner tube insertion apparatus which can readily be carried on a vehicle for use in the field.
The object of the present invention is to meet such need by providing a relatively simple, lightweight inner tube insertion apparatus, which can be used on a tire changer already mounted on a truck or other vehicle. In other words, the I insertion apparatus is a kit which can be added to existing -tire chanters.
Accordingly, the present invention relates to a stiff inner tube insertion apparatus for use with a conventional tire changer of the type including a base, a frame on one end of the base, a first carriage slid able on the frame for vertical Jo ~LZ~35~5 movement thereon, tire support arms on the first carriage for holding a tire in a substantially vertical position above said one end of the base, tracks on the base, and a second carriage slid able on the tracks for movement towards and away from said one end of the base, said apparatus comprising ramp means pivotal connected to the other end of said base; slide means on said ramp means for supporting an inner tube above said second carriage;
and force transfer means for connecting said slide means to said second carriage whereby movement of said second carriage towards and away from said one end of the base results in corresponding movement of said slide means towards said tire to force the inner tube into the tire.
The invention will now be described in greater detail with reference to the accompanying drawing, which illustrates a preferred embodiment of the invention, and wherein:
Figure 1 is a schematic, perspective view from above and one end of an inner tube insertion apparatus, with parts omitted; and Figure 2 is a schematic, side elevation view of the I apparatus of Fig. 1 in use.
With reference to the drawing, the apparatus of the present invention is designed to insert an inner tube 1 into a tire 2. The inner tube 1 is of the heavy duty, military vehicle type which is designed to run flat, i.e. with little or no air pressure. For such purpose, the tube 1 is formed of heavy, fabric reinforced rubber, and consequently is relatively stiff Sue and difficult to handle. before normal insertion of -the tube 1 into a tire 2, a belt 3 is placed around the tube and pulled tight to bring opposite sides of the tube together. Thus, rather than being annular, the tube assumes a figure eight shape.
PRIOR ART MACHINE
The insertion apparatus is designed as a kit for use with a conventional tire changer of the type including a feat-angular base 4 and a pair of tracks 5 mounted on the base 4.
I The tracks 5 are defined by a pair of elongated metal tubes extend-in between sleeves 7, which arejfixedly mounted on the base 4.
A carriage generally indicated at 8 is slid ably mounted on the tracks 5 for horizontal movement thereon. The carriage 8 is defined by a rectangular body 9 and a sleeve 10 on each side thereof. A longitudinally extending row of pockets 11 is provided in the centre of the Bud. The carriage 8 is caused to move along the tracks 5 by means of a hydraulic cylinder 12 and a piston rod (not shown) extending out of one end of the cylinder 12 and connected to one end of the carriage 8. The other end of I the cylinder 12 is connected to a frame 13 including vertical posts 14. A carriage 15 is slid ably mounted on the posts 14 or vertical movement thereon. A turntable 16 and so-called wheel chuck arms 18 are mounted on the carriage 15.
APPARATUS OF TIE PRESENT INVENTOR
The ramp 20 is defined by a rectangular frame, including ,3S~5 sides 21, a bottom end 22 and a top end 23~ The bottom end 23 of the ramp is pivotal connected to one end 25 of the base 5 by a pin 26. The pin 26 extends through one of a row of holes 27 in a bracket 28 on the end 25 of the base 5, and through arms extending downwardly from the end 23 of the ramp 20. Thus, the position of the ramp 20 can be adjusted for use on machines of different sizes. Two fixed lugs 30 and one rotatable lug 31 extend outwardly from the other end 22 of the frame 20. The lugs 30 and 31 are generally L-shaped for gripping the beaded inner edge 32 of the tire 2. A hinge 33 in the lug 31 permits rotation of the outturned thereof, so that the lugs can be inserted readily into the tire 2.
The inner tube 1 is pushed into the tire by means of a slide 34, which is slid ably mounted on the ramp 20. The slide lo 34 includes an inverted L-shaped frame 35 with a tire engaging pad 36 on one side thereof. A pair of gussets 37 extend outwardly from the other side of the frame 35. A generally triangular top plate 38 is connected to the gusset 37 on each end of the frame 35, and the top plate 38 is connected to a similar bottom plate I 39 by nuts and bolts 40 (one shown). A force transfer arm 42 connects the slide 34 to the carriage 10. The arm 42 includes an inclined top end 43 extending upwardly between the plate 38 and 39 for engaging the shoe 34. An L-shaped bottom end 45 engages the carriage 10.
I The tube 1 is guided upwardly in the tire 2 by a deflector 1~23S~5 46. The deflector 46 is mounted on the outer ends of the wheel checkrooms 18. The deflector includes a plurality of radially extending arms 48.
In use r a tire 2 is mounted on the stand 13. The lugs 30 and 31 are placed in the tire 2 (Fig. 1). The wheel chuck arms 18 are raised with the vertical carriage 15 which pulls the tire open fig. 2). Then, the horizontal carriage 8 is moved towards the frame 13. Force is applied to the slide 34 through force transfer arm 42 to push the tube 1 into the tire I 2. Once the tube 1 has been partially inserted, the deflector 46 causes the tube to bend upwar~ly'into the top of the tire.
Continued movement of the carriage 8 towards the frame 13 results in complete insertion of the tube into the tire. the carriage 15 is then lowered so that the tire 2 can be removed.

APPARATUS OF TIE PRESENT INVENTOR
The ramp 20 is defined by a rectangular frame, including ,3S~5 sides 21, a bottom end 22 and a top end 23~ The bottom end 23 of the ramp is pivotal connected to one end 25 of the base 5 by a pin 26. The pin 26 extends through one of a row of holes 27 in a bracket 28 on the end 25 of the base 5, and through arms extending downwardly from the end 23 of the ramp 20.

I The tube 1 is guided upwardly in the tire 2 by a deflector 1~23S~5 46. The deflector 46 is mounted on the outer ends of the wheel checkrooms 18. The deflector includes a plurality of radially extending arms 48.
In use r a tire 2 is mounted on the stand 13. The lugs 30 and 31 are placed in the tire 2 (Fig. 1). The wheel chuck arms 18 are raised with the vertical carriage 15 which pulls the tire open fig. 2). Then, the horizontal carriage 8 is moved towards the frame 13. Force is applied to the slide 34 through force transfer arm 42 to push the tube 1 into the tire I 2. Once the tube 1 has been partially inserted, the deflector 46 causes the tube to bend upwar~ly'into the top of the tire.
Continued movement of the carriage 8 towards the frame 13 results in complete insertion of the tube into the tire. the carriage 15 is then lowered so that the tire 2 can be removed.
