Definitions
- a carpet roll unloading and transporting assembly comprising an elongated. rectangular frame with legs extending downwardly from the corners and 31: :g dg terminating in castors.
- An electrically driven drum is [58 5 provided at one end of the assembly which winds and 1 0 1 85 unwinds a pair of cable members to raise and lower l rolls of carpeting for transporting or cutting off of por- [56 R I Gt 6 tions for use.
- One of the cables is used in the assembly 1 UNITE]; g zzflis PZTENTS for unloading of rolls of carpeting from a truck.
- Our invention provides equipment which, in one piece of apparatus, will provide an unloading tool for removal of carpeting from trucks and the like and will also readily move large rolls of carpeting throughout a store or other facility safely and economically.
- the assembly is such that it can readily move down very narrow aisles and turn very sharp corners. Thus, it maximizes the amount of useful space in a storage area.
- the invention accomplished all these purposes through the use of a rectangularly-shaped frame member having a length several times its width, with leg members extending from the four corners of the rectangular frame and terminating in castors at the base thereof.
- the legs are constructed to readily change to any desired length and will ordinarily be from six to nine feet in length. They are constructed in such a manner as not to require cross bracing therebetween, a fac tor which adds to the versatility of the assembly for purposes that will be described more completely hereinbelow.
- a motor and cable-winding drum is provided at one end of the assembly, having two cables independently wound thereon. The first cable is adapted to extend directly downwardly from the drum to act as a hoist member on one end of the frame.
- a second cable is considerably longer than the first and extends, when fully extended, well beyond the opposite end of the assembly, so as to permit winding about rolls of carpeting in the back of a truck or the like.
- the assembly can be utilized to pull carpeting away from the bed of a truck and into position for hoisting into the center of the frame assembly for transportation to other parts of the store.
- a plurality of cross bar members are provided having hook means attached thereto for mounting of pulley members.
- the pulley members are adapted to releasably engage the longer cable-to provide the second lift member for elevating carpeting for transportation, cutting or other purposes.
- a removable cutting bar is also provided.
- FIG. I is a side elcvational view of the apparatus in accordance with our invention showing its use in two different manners;
- FIG. 2 is an end elevational view of the apparatus in accordance with FIG. 1 illustrating an additional use
- FIG. 3 is a perspective view of a cutting bar for utilization in the manner described in FIG. 2;
- FlG. 4 is a schematic illustration of a two-member cable winding drum.
- FIGS. 1 and 2 there is illustrated a carpet unloading and transporting assembly in accordance with our invention.
- Thisassembly consists of an upper portion of elongated rectangular configuration generally designated 10, which is advantageously,
- the rectangular frame described is one with a length of about 17% feet X 40 inches in width.
- the angle irons are joined at the corners of the rectangular frame by appropriate means such as welding to square steel tubing 11, which may be of a size 2%X2'kX3/l6-inch, with an overall length of about 14 inches.
- the side rail angle iron members have been exaggerated as to their width dimensions relative to the scale of the rest of the assembly.
- the corner post members 11 have a steel cap welded across the upper portion thereof to present a closed end tube. Telescoping partly into and extending downwardly from the corner post tubes 11 are leg members 12, which are advantageously formed from 2 2X3/16-inch steel tubing.
- leg members 12 will depend upon the needs of the user, but will ordinarily be of a length. of 6 feet or longer.
- Tube members 12 terminate in a. castor assembly 13, which includes a wheel member 1-4.
- the upper portion 13 of the castor assembly is shown as a rectangular steel tube of similar dimension to member 1 1 and into which member 12 telescopes.
- a fastening means such as set screws may be utilized in members 11 and 13 to hold the leg members 12 within the tubulations. As can be seen, the set screws are not required, as the weight of the assembly will hold the tubes in their respective positions.
- Switch box 17 is shown as having two buttons which operate electric motor 15 in either a forward or reverse direction. Not shown is a means for supplying electric power through switch box 17 to motor 15. A simple plug-in to an extension cord, would be one such means.
- Motor 15 is connected to cooperate with a gear box 18, which in turn is in operable engagement with a drum member 19.
- support bars 20, 21 and 22 Attached at various positions along the length of frame 10 intermediate the long sides thereof are support bars 20, 21 and 22. These bars are fixedly mounted to the angle irons of the longitudinal sides of frame 10. Bars 20, 21 and 22 have a means such as a hook 23 attached thereto, which is adapted to engage and hold a pulley member 24. As shown in FIG. 1, pulley 24 is mounted at the furthest end from the motor and drum assembly.
- a pair of independently wound cable members 25 and 26 are in engagement with drum 19 and are wound and unwound by the rotation of the drum. Cable 25 extends vertically downwardly from drum 19 and engages a steel rod 27, which extends through a carpet roll 28 and provides support therefor.
- Cable 25 is provided at the end thereof with a means such as a permanent loop 29 for slipping around the steel rod 27.
- Cable 26, in solid line, extends from drum member 19 through pulley 24 and down to the opposite end of rod 27 to provide a second lift point for the carpet 28. It can now be readily understood that carpet 28 may be either raised or lowered by rotation of drum 19 through power supplied by motor 15.
- Carpeting comes in a variety of lengths, and normally is sold in 6-foot, 12-foot or 15-foot lengths. In the form shown in FIG. 1, a 15-foot length of carpeting is illustrated as being raised. For shorter lengths of carpeting, it is desirable that the cable 26 engage steel rod 27 at a point near the carpeting, rather than at some end remote from the actual carpeting. There is less tendency to bend rod 27 if the support points are near the carpeting, as the carpeting and its inserted liner gives some support against bending. Therefore, we have provided additional points for pulley member 24, such as cross beams and 21, appropriately positioned to take into account the varying carpet lengths. By positioning a pulley either permanently or movably to the other support positions, one can readily accommodate different lengths of carpeting rolls.
- a truck having a tailgate 31 In a second use of the assembly of our invention, there is illustrated a truck having a tailgate 31.
- the assembly in accordance with our invention is moved into position against tailgate 31 so that legs 12 are in contact therewith.
- Cable member 26 has been slipped off of pulley 24 and has een extended outwardly into the back of truck 30 and looped about a roll of carpeting.
- the permanent loop 29 may be used to form a slip noose arrangement for engaging the end of the carpeting.
- the motor is then activated to pull the roll of carpeting out from the body of truck 30 and in between the upstanding legs 12.
- FIG. 2 there is illustrated an assembly in accordance with our invention wherein a roll of carpeting 28 has been elevated to a point above a cutting bar 32, shown in greater detail in FIG. 3.
- the cutting bar is detachably mounted to the legs 12 by means such as studs 33, which are adapted to engage keyholes 34 of member 32. It should be noted at this point that legs 12 have no obstructions therebetween at the lower portions thereof. This permits the entire assembly to be rolled about and to pass over rolls of carpeting such as illustrated in FIG. 2 from a sideward motion of the frame, as well as to extend over single rolls of carpeting longitudinally. As the cutting bar is only used a portion of the time, it is desirable that it be readily attachable and detachable.
- FIG. 3 there is illustrated a preferred form of cutting bar, which involves a plate member having secured thereto an elongated cylindrical tube 35, having a slot running the length thereof at the upper surface.
- Brace members 36 are provided at the ends of the tube to hold it rigidly in place and to prevent it from rotating.
- a length of carpeting has been unwound from roll 28 and lapped over the cutting bar 32.
- a length of carpeting may be removed by a cutting tool such as knife 37, utilizing the cutting tool guide 32 to make a straightline cut.
- rolls of carpeting may be piled as illustrated, or they may be removed from the pile regardless of their position therein.
- the assembly 10 may be positioned over the rolls of carpeting and a steel rod 27 inserted therethrough any member such as 28, 28' or 28".
- the drum Upon activation of electric motor 15, the drum will wind up cables 25 and 26 and raise the desired roll of carpeting up into position above the pile of carpeting so that it can he moved to some other position or have a section of carpeting cut therefrom.
- the rod sections should be formed of steel tubing having a telescoping member fixedly fastened to one end thereof for insertion into a cooperating adjacent section of tube to provide the desired overall length. We have found that individual sections of about four-foot lengths may be joined in such a manner to give any desired length.
- FIG. 4 there is illustrated in schematic form a drum assembly consisting of two separate members which are adapted to cooperate.
- cable 25 will be unwound and either deposited on the surface or be of such a length as to be rewound on drum 19 as cable 26 is extended.
- FIG. 4 illustrates one means of separately winding cables 25 and 26, so that they either cooperate in movement with one another or can be independently wound and unwound.
- shaft 38 extends rotatably through support members 39 and has positioned thereon two drums 40 and 41.
- Drum 40 is fixedly attached to shaft 38 by some appropriate means such as welds.
- Drum member 41 is journaled onto shaft 38 and is free to rotate thereon.
- a spring member 42 is positioned along shaft 38 to bias member 41 into engagement with fixed drum 40.
- clutch means such as a gear ring so that both drums will rotate simultaneously when in engagement.
- drum 41 is pulled along shaft 38 out of engagement with the clutch means by appropriate means (not shown).
- drum 41 is disengaged so as not to rotate with drum 40.
- the cables can then be positioned relative to one another as desired.
- Any appropriate means may be utilized to hold the cable members onto drums 19, 40 or 41, such as a hook member 43.
- the most desirable cable is a one-half-inch diameter nylon rope.
- a one-half-inch nylon rope has a tensile strength of about 5,000 pounds.
- the nylon rope has proved to be most satisfactory for this purpose, as it is clean, requires no lubrication, and does not have a tendency to fray and interfere with handling of materials, as is the case with steel cable. Likewise, it is relatively inexpensive and does not tend to kink.
- a manually movable carpet roll unloading and transporting assembly capable of handling a variety of carpet roll sizes, comprising:
- a rectangular frame member having a length several times the width thereof and having a plurality of cross bar members between the long sides thereof and intermediate the ends, said cross bar members having means for mounting a pulley therefrom;
- leg members in engagement with and extending substantially vertically downwardly from the corners of said rectangular frame and terminating in castors, said legs defining obstruction-free openings therebetween over the major portion of their length;
- a drum rotatably mounted to said frame member adjacent one end thereof with its axis of rotation transverse to the long sides of said frame;
- pulley means attached to at least one of said cross bar members remote from said drum, said pulley means constructed to releasably engage a cable;
- nylon rope cable mounted to said drum to provide two free ends of cable, the first of said free ends of cable extending downwardly from said drum to at least the base of said legs in the unwound condition to provide a first vertical lifting means at the drum end of said frame, the second of said free ends extending from said drum in a first operative position over said pulley means and downwardly therefrom to thereby provide a second vertical lifting means at a position remote from said drum end and extending directly from said drum between and beyond the legs of the opposite end of said frame so as to provide a means for drawing a carpet from the bed of a vehicle into a position intermediate said leg members; and
- a manually movable carpet roll unloading and transporting assembly capable of handling a variety of carpet roll sizes, comprising:
- a frame member having a length several times the width thereof, said frame member including at least one longitudinal support member having means for mounting a pulley member therefrom;
- leg members in engagement with and extending substantially vertically downwardly from the corners of said frame and terminating in castors, said legs defining obstruction-free openings therebetween over the major part of their length;
- a drum rotatably mounted in supportive relation to said frame member near one end thereof, with its axis of rotation transverse to the longitudinal axis of said frame;
- pulley means supported by said longitudinal support member at a point substantially removed from said drum member, said pulley means constructed to releasably engage a cable
- nylon rope cable mounted to said drum to provide two free ends of cable, the first of said free ends of cable extending downwardly from said drum to at least the base of said legs in the: unwound condition to provide a first vertical lifting means at the drum end of said frame, the second of said free ends extending from said drum in a first operative position over said pulley means and downwardly therefrom to thereby provide a second vertical lifting means at a position remote from said drum end and extending directly from said drum between and beyond the legs of the opposite end of said frame so as to provide a means for drawing a carpet from the bed of a vehicle into a position intermediate said leg members; and
