Referring more in detail to the drawings: As required, detailed embodiments of the present invention are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms that are different from those illustrative embodiments presented herein. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting but merely as a basis for the claims actually defining the scope of this invention. In this regard, his to be recognized thattransporting structures, in accordance herewith, maybe embodied in various forms and, furthermore, that such transports ing structures may be towed by any suitable prime mover and that the structure of the frame may be formed in any manner to provide a suitable rigid and sturdy construction. However, the disclosure hereof is presented only as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriate detailed structure.

In the disclosed embodiment of the present invention, the reference numeral 1 generally designates a transporting structure for transporting material in coils, on reels or drums and particularly coils of hot wire, strip, and the like, and includes a generally U-shaped mobile frame 2 having a forward end portion 3 suitably connected to a prime mover or tractor 4 and an elongated ram 5 positioned between-transversely spaced

side members

6 and 7 of the mobile frame 2. One end 8 of the ram 5 is mounted on a ram support 9 operatively connected to the mobile frame 2 for movement of the ram 5 between a retracted position 10 and an extended position 1 1.

The illustrated mobile frame 2 including. the forward end portion 3 and the transversely spaced side mem bers 6 and 7 extending rearwardly therefrom may be formed of suitable structural elements, such as plates, angles, and the like, to form generally box-shaped members which are effective to support substantial loads, such as in the nature of 80,000 pounds (80,000 lbs.) or greater. The forward end portion 3 and the

arms

6 and 7 each have top and bottom members 12 and 13 respectively and suitable laterally spaced side wall members 14and 15. The frame 2 is suitably supported on wheels and may have two or multiples thereof. In the illustrated structure, the

side members

6 and 7 have wheels 16 and 17 respectively rotatably mounted thereon and adjacent an exterior side wall, thereof intermediate the ends thereof. It is preferable that the wheels 16 and 17 have suitable

pneumatic tires

18 and 19 respectively mounted the the mobile frame 2 and the load thereon.

The coils or rolls of material are received from a'roll- Y tended position 11, and also from objects that may be adjacent a path of travel. 7

In the illustrated structure, the wheel guards or housings 20 and 21 each have a frame portion 24 formed of suitable structural members, such' as beams, angles, channels, and the like, whichcooperates with an exteeon for supporting rior surface and a rear end of the

respective side members

6 and 7 to thereby enclose the

tires

18 and 19. A suitable side plate 25 is secured to the

side members

6 and 7 and the rearwardly extending

portions

22 and 23 of the wheel guards or housings 20 and 21 and extends upwardly therefrom to provide a cover or guard for the upper portion of the

tires

18 and 19. Top plates 26 extend outwardly from an upper edge of the side plates 25 to provide a cover for at least a portion of the tread portion of the

tires

18 and 19.

The forward end portion 3 of the mobile frame 2 is suitably connected to the prime mover 4 and in the illustrated structure, said prime mover may be a two wheel tractor and the connection has parts operative to effect relative movement therebetween. In the illustrated embodiment, upper and

lower ears

27 and 28 extend forwardly from the forward end portion 3 of the mobile frame 2 and are preferably centered on a longitudinal central axis of the mobile frame 2. The

ears

27 and 28 are suitably pivotally connected to upper and

lower frame portions

29 and 30 respectively of the prime mover 4 whereby the mobile frame 2 is hingedly connected to the prime mover 4 and is highly maneuverable about the pivotal mounting of the

frame portions

29 and 30 on the upper and

lower ears

27 and 28.

A pair of transversely spaced ears 31 and 32 are mounted on the forward end portion 3 and centered on the longitudinal central axis of the mobile frame 2 for pivotally supporting one end of

extensible power members

33 and 34 respectively which are operatively connected to the power system of the prime mover 4 and have the other ends thereof pivotally mounted on the prime mover 4. Operation of the

extensible power members

33 and 34 by extending one and retracting the other is effective to move the mobile frame 2 about the pivotal mounting of the

frame portions

29 and 30 on the

ears

27 and 28 respectively.

The ram support 9 is positioned between the

side members

6 and 7 of the mobile frame 2 and is adjacent the forward end portion 3 of the mobile frame 2 and has the one end 8 of the elongated ram supported thereon and extending outwardly and rearwardly therefrom. Movement effecting means extend between the mobile frame 2 and the ram support 9 for supporting the ram support 9 and for effecting movement thereof relative to the mobile frame 2 for moving the ram 5 between the retracted position and the extended position 11.

The illustrated ram support9 may be cast or fabricated of suitable structural members, such as plates, beams, angles, channels, and the like, to form a substantially rigid structure having a bore 35 adjacent a lower edge 36 thereof and laterally centered in the ram support 9 to receive the one end 8 of the ram 5. A lift arm 37 has one end thereof pivotally mounted on the ram support 9 adjacent the lower edge 36 thereof and in the illustrated structure, pivotal mounting means 38 and 39 on an axis that intersects the axis of the aperture 35 and is normal to the axis of the ram 5 for pivotally supporting portions 40 and 41 respectively of the lift arm 37. Bars 42 and 43 are on the ram support 9 and extend upwardly from an upper edge 44 thereof for pivotally mounting one end of power means in the form of extensible members 45 and 47 respectively for raising and lowering and retracting and extending the ram 5. An intermediate portion of the ram support 9 has pivotal mounting means 47 and 48 for pivotally supporting one end of ram tilting means in the form of

extensible members

49 and 50.

The lift arm 37 and the

extensible members

45 and 46 and 49 and 50 support the ram support 9 and the extensible members are arranged in spaced sets of pairs and have one end pivotally mounted on the ram support 9 and the other end pivotally mounted on the forward end portion 3 of the mobile frame 2, as later described, to effect movement of the ram support 9 and the ram 5 thereon between the retracted position 10 and the extended position 11 and to tilt the ram 5 above and below the horizontal, as later described.

The forward end portion 3 of the mobile frame 2 has a generally upright rearwardly facing surface having upper and

lower edges

51 and 52 respectively and the ram support 9 is a generally upright member which is moved generally parallel with the rearwardly facing surface of the forward end portion 3. The lift arm 37 extends between the lower edge 52 of the forward end portion 3 and the lower edge 36 of the ram support 9 and has respective opposite ends thereof pivotally mounted adjacent the

lower edges

52 and 36 of the forward end portions 3 and the ram support 9 respectively whereby the ram support 9 has the lower edge 36 thereof moved in a generally arcuate path relative to the lower edge 52 of the forward end portion 3 whereby lowering the ram support 9 and the ram 5 thereon extends the ram outwardly from the forward end portion 3 and raising the ram support 9 moves the ram support 9 and the ram 5 thereon toward the forward end portion 3 thereby retracting same.

The extensible members 45 and 46 are operative to raise and lower the ram support 9 and each have the one end thereof pivotally mounted on the ears 42 and 43 extending from the upper edge 44 of the ram support 9 and the other ends thereof pivotally mounted on the forward end portion 3 adjacent the lower edge 52 thereof whereby extension of the extensible members 45 and 46 raises the ram support 9 and retraction of the extensible members 45 and 46 lowers the ram support 9 and the ram 5 thereon.

The

extensible members

49 and 50 are operative to tilt the ram 5 above and below the horizontal while the ram 5 is in the extended position 1 l or the retracted position 10 or any position therebetween, such as to load and unload the coils or material. The

extensible members

49 and 50 each have the one ends thereof pivotally mounted on the ram support 9 intermediate the upper and

lower edges

44 and 36 respectively thereof and the other ends are pivotally mounted on the rearwardly facing surface of the forward end portion 3 adjacent the upper edge 51 thereof. Extension of the

extensible members

49 and 50 effects tilting of the ram 5 below the horizontal and retraction of the

extensible members

49 and 50 effects tilting of the ram 5 above the horizontal.

Heretofore, ram members for supporting hot coils of wire, strip, and the like, were centrifugally cast steel which was extremely expensive to form. The ram 5 of the coil transporting structure 1 is substantially less expensive to form, such as in the nature of 10 to l5, percent of the cost of centrifugally cast steel. The ram 5 is formed of an elongated tubular member 53 having diammetrically opposed longitudinally extending

coil support portions

54 and 55 suitably secured, as by welding, on an exterior surface of the tubular member 53. The

coil support portions

54 and 55 extend along the exterior surface of the tubular member 53 to positions adjacent respective opposite ends thereof. In the illustrated structure, the

support portions

54 and 55 are on the top and bottom of the tubular member 53 whereby the coil engages same and the interior of the coil is spaced from the portion of the tubular member between the s upport portions. This arrangement provides thick upper and lower wall portions with great of the tubular member 53 and has an exterior surface I having portions thereof alignablewith exterior surfaces of the tubular member 53 and the

coil support portions

54 and 55.

In using a coil transporting structure, constructed as illustrated and described, the prime mover 4 positions the ram 5 of the coil transporting structure 1 in position to receive rolls, reels or coils of hot wire, strip, and the like. The

extensible members

49 and 50 are operated to upwardly tilt the free end of the ram 5 above the horizontal to move the coils along the ram and toward the ram support 9. When the ram 5 has been loaded, the prime mover 4 is operative to maneuver the coil transporting structure 1 to a position for storing the coils until sufficiently cooled for further handling. It is preferred to operate the extensible power members 45 and 46 to raise the ram 5 and move the ram support 9 to a retracted position while transporting the coils. When it is desired to remove the coils from the ram 5, the

extensible members

49 and 50 are operated to lower the free end of the ram 5 below the horizontal thereby effecting movement of the coils along the ram 5. Operation of the

extensible power members

33 and 34 is operative to maneuver the mobile frame 2 both while the prime mover 4 is stationary and while the prime mover 4 is tilting the mobile frame 2 to thereby position the ram 5 in a desired position to receive or unload the coils.

It is to be understood that while I have illustrated and described one form of my invention, it is not to be limited to this specific form or arrangement of parts herein described and shown.
