Int. Cl. A47f 7/00 U.S. Cl. 211-49 11 Claims ABSTRACT F THE DISCLOSURE A framework is mounted on wheels so as to be readily movable. A plurality of support portions are mounted on the framework and are normally inclined with respect to horizontal so that cheeses or cones supported thereby will move toward one end thereof. The support means for cones includes at least two elongated guide portions adjustably mounted to accommodate different size cones to ensure proper rolling movement thereof. In a modified form of the invention, further support portions are mounted on the framework and are inclined oppositely to the first-mentioned support portions and at a greater angle with respect to horizontal for receiving empty starters or bobbins.

BACKGROUND OF THE INVENTION The present invention relates to movable support means commonly called cheese trucks and employed in the textile industry for moving and loading or unloading cheeses and cones with respect to textile machines.

Movable support means for cheeses and cones have been used for many years in the textile industry for loading and unloading operations with respect to a machine. For example, such support means are employed for moving a full package including a central starter or bobbin having thread wound thereon to a loom in the weave room where an operator removes the packages from the support means and applies them to the loom. This is often ineiecient when employing prior art arrangements since it is sometimes necessary for the operator to walk around the truck or reach through the side of the truck, which cannot be accomplished due to the space restrictions between adjacent machines.

Such support means are adapted to receive both cheeses and cones. The cheese generally has a substantially cylindrical outer configuration, while the cones are substantially frnsto-conical in shape. These cones come in different sizes and the taper thereof may be within a relatively wide range. A particular problem arises when such cones are carried by a movable support means and are designed to roll downwardly along suitable support portions thereof. The cones tend to roll in circles and will bind in the support portions which are generally of channel-like shape. As a result, the cones do not roll properly along the support portions and will not automatically be disposed in proper position for handling by an operator.

Additionally, when it is desired to unload a package from a machine and place it on the support means while further placing empty bobbins on the machine from a support means, special handling trucks have been employed in the prior art for loading while other trucks are employed for unloading. Accordingly, two trucks have been required for carrying out this dual function operation resulting in an ineicient arrangement and excessive fatigue of the operator.

Additionally, such prior art movable support means have been excessively heavy and bulky in construction.

Patented Mar. 10, 1970 SUMMARY oF THE INVENTION The present invention employs a framework which carries support means including at least two elongated support portions which are spaced from one another. At least one of these support portions is adjustable relative to the other cooperating support portion to vary the spacing therebetween. Accordingly, this adjustable spacing may be varied as required in accordance with the size and taper of the cone to be supported thereby to ensure that the cones will roll properly along the support portions and will not bind. The cones are thereby allowed to roll freely and are properly guided in their movement so that they will be disposed in position automatically to be readily grasped by an operator standing at one end of the support means.

Additionally, the support portions of the present invention which comprise two elongated support portions substantially reduce the amount of friction between the cheeses or cones and the associated support portions, while at the same time serving as means for accurately guiding movement particularly of cones supported thereby.

In a modified form of the present invention, an arrangement is provided wherein a single movable support means is adapted to be employed when carrying out the dual function of unloading and loading a machine from one end of the movable support means. This reduces the number of support means required and also substantially cuts down on the amount of effort required by the operator so as to minimize fatigue.

This modified form of the invention enables the same number of full packages to be loaded onto the support means as the number of bobbins which are carried by the support means and are adapted to be mounted on the machine.

The present invention provides a lightweight, yet compact and rigid movable support means. Means is further provided for protecting threads on the corners of cheeses or cones supported at the end portions of the support means, and a novel wheel arrangement is provided whereby the support means may be readily tilted to place it in proper operative position.

In still a further modied form of the invention, the support portions of the guide means at one end thereof are provided with reinforcing means in the form of gusset plates or the like so that this end of the guide means serves to provide steps upon which an operator can climb thereby forming a ladder so vthat as the package is rolled down 'toward the operator on t'he rea-r and he is loading them into a creel which is considerably above his head, the effective ladder means simplifies his loading problems.

An object of the present invention is to provide a' new and novel movable support means for cheeses and cones as employed in the textile industry, and which is lightweight and compact in construction, and further which willproperly feed cones from one end thereof to the other, and further whichv enables loading and unloading operations to be carried out'at the same time from one' end of the support means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings wherein like reference characters designate corresponding parts throughout the several views, a first form of the invention is illustrated in FIGS. 1-4 inclusive. As seen particularly in FIGS. 1 and 2, the movable support means includes an open framework having a base portion including opposite longitudinally extending parallel side members and 12 which are interconnected at the opposite ends thereof by

end members

14 and 16 disposed in spanning relationship between

members

10 and 12. All of these members may be formed of a suitable material such as stainless steel, galvanized iron, aluminum, Fiberglas, rigid plastic or the like which will provide a strong structure 4which is of lightweight construction. The members may be suitably interconnected with one another in accordance with the material used to provide a rigid framework.

A pair of

cross frame members

20 and 22 extend between the

side frame members

10 and 12 and are rigidly aflixed thereto in parallel relationship and spaced from the

opposite end members

14 and 16 respectively. A further pair of

cross frame members

24 and 26 extend between the

side frame members

10 and 12 at the medial portion of the base of the framework.

A member 28 is secured between

cross frame members

24 and 26 and supports intermediate portions of cross brace members 30 and 32, the ends of which are secured to

side frame members

12 and 10 respectively. This overall arrangement provides a very rigid and yet lightweight construction.

A swivel 4wheel assembly indicated generally by reference numeral 40 is supported by frame members 1-4 and 20, and a similar swivel wheel assembly indicated by reference numeral 42 is mounted between

frame members

16 and 22 at the opposite end of the framework.

Wheel assemblies

40 and 42 may also be mounted for rotation about xed axes rather than being of swivel type in some cases. A pair of

wheel assemblies

44 and 46 are mounted for rotation about lixed axes and are supported by the

frame members

24 and 26. As seen most clearly in FIG. l, the diameter of the wheel assemblies 44 and 46 which are identical with one another is greater than the diameter of the -wheel assemblies I40 or 42. These wheel assemblies form an anti-friction means which enables the support means to be readily moved from place to place, the larger diameter central wheel assemblies permitting the support means to be readily tilted in either direction so that one or the other ends of the support means can be lowered as desired.

Four

upright members

50, 52, 54 and 56 extend vertically from the four corners of the base of the framework, these latter members being channel members as seen most clearly in FIG. 2. Four cylindrical or

tubular members

60, 62, `64 and 66 also extend upwardly from the base of the framework

adjacent members

50, 52, 54 and 56 respectively, these cylindrical members providing a rub guard or bumper means to prevent damage to the framework.

As seen most clearly in FIG. 3, an uppermost pair of troughs or channel members 70 are provided, these members being spaced laterally with respect to one another and as seen in this gure are secured to the inwardly facing surfaces of the

upright members

50 and 52 in any suitable manner as by Welding or the like. As seen in FIG. l, this pair of channel members 70 slope downwardly from the right-hand side of the support means toward the left-hand side thereof, or in other words they are inclined with respect to horizontal. Similar pairs of

troughs

72, 74, 76 and 78 are disposed in parallel relationship to the rst described pair of troughs 70 and are similarly supported and oriented with respect to the remaining portions of the framework. Any suitable number of pairs of troughs may be employed in accordance with the plant space available and the size of the package to be utilized.

As seen in FIG. 1, the left-hand end of the channel members 70 may be supported by a cross member 80 which may comprise a rod having the opposite ends thereof rigidly aixed to the

upright members

50 and 52. Similarly, the right-hand end of the channel members 70 is supported by a rod 82 extending between the

upright members

54 and 56. Cross members 84 similar to cross member l serve to support the left-hand end of the remaining channel members, and cross members 86 similar to cross member 82 serve to support the right-hand end of the remaining channel members.

As seen in FIGS. 3 and 4, each of channel members 70 includes a base wall 90 having integral side walls 92 and 94 extending substantially normally therefrom and terminating in generally cylindrical tubular

upper end portions

96 and 98 which are adapted to receive cylindrical rods therein. The construction of all of the channel members and the associated support portions as hereinafter described is identical, and accordingly, the specic structure of the uppermost channel members and the associated structure will suffice for a description of all of the similar components of the apparatus.

A rod member 100 is supported within the tubular portion 96 and extends outwardly therefrom and is curved at the outer end thereof to join with a laterally extending portion 102 which serves as a stop means for a purpose hereinafter described. This portion 102 in turn joins with a rod portion 104 extending within the tubular portion 98 of the other of the two channel members 70 as may be seen most clearly in FIG. 3. A further pair of

rod members

106 and 108 are received within the

tubular portions

98 and 96 respectively of the two channel members and have the ends thereof rigidly secured to the portions 102.

As seen most clearly in FIGS. l and 2, a plurality of inner guide means 110 are secured between the adjacent pairs of channel members, these inner guide means being of generally triangular configuration so as to guide cheeses or cones into the channel members. As seen most clearly in FIG. 2, further outer guide means 112 are secured between the outer edge portions of the various channel members and the adjacent upright members to also serve to effectively guide cheeses or cones into the channel members when inserting same from the righthand end of the apparatus as seen in FIGS. l and 2.

As seen most clearly in FIGS. 3 and 4, the support means for supporting cheeses or cones on the structure includes guide means comprising a pair of elongated support portions and 122 supported by each of the channel members 70. These

portions

120 and 122 are of tubular construction, and as seen most clearly in FIG. 4 include depending

lugs

124 and 126 respectively which extend downwardly through slots `and 132 provided in each of channel members 70 adjacent the end thereof and extending laterally of the structure. Nut and washer assemblies 134 and 136 are threaded on the lower threaded ends of

lugs

124 and 126 as seen in FIG. 4 for securing the elongated guide portions in a particular spaced relationship with respect to one another.

Similar slots

140 and 142 are provided through the opposite end portions of the channel members 70 for enabling the opposite ends of the

elongated guide portions

120 and 122 to be similarly adjusted. The

guide portions

120 and 122 will ordinarily be disposed in parallel relationship with one another, and the spacing therebetween can be altered in accordance with the size and taper of the cones to be supported thereon.

It should be understood that each of the channel members of the support means is provided with pairs of similar slots adjacent opposite ends thereof, and similar guide portions 146 as seen in FIG. l are disposed within each of the channel members to support cones therewithin. As noted in FIG. 1, the stop means 12 is disposed beyond the ends of the support portions120 and 122 to serve as a stop means to enable cones or cheeses supported by the apparatus to be limited in their downward movement on the support portions. Similar stop means 148 is provided in association with each of the remaining channel members of the apparatus.

Various cones are indicated by phantom lines 150 supported in operative position on the apparatus, and various cheeses 152 are indicated by phantom lines in operative position in the apparatus. It is apparent that the full packages can be loaded at the right-hand end of the apparatus as seen in FIG. l and will automatically roll downwardly into the operative position shown in FIG. l at the left-hand end of the apparatus for removal therefrom.

As seen in FIG. 4, a cone may be so supported by the

support portions

120 and 122 that it will roll in a straight line downwardly along the inclined support portions and will not tend to bind, Accordingly, the adjustable support portions enable the apparatus to be adjusted so that it can effectively receive and guide rolling movement of cones of varying size and configuration. Furthermore, these spaced support portions in association with both cones and cheeses provide line points of contact which minimize friction as lthe cheeses or cones roll downwardly therealong.

It should also be noted that in some instances the guide means including the

support portions

120 and 122 may be removed, particularly when generally cylindrical cheeses are used, for example.

Referring now to FIGS. -8 inclusive, a modified form of the invention is illustrated wherein the support means includes the same basic components as discussed in connection with FIGS. 1'4, and similar portions have been given the same reference numerals primed. Additional structure is incorporated in this form of the invention for enabling the structure to carry out a dual function.

It will be noted that the framework arrangement is substantially identical with that peviously described in that the same base means and upright members are provided, although these upright members in Vthis casemay comprise bars instead of channel members, but nevertheless the corresponding members serve the same function. A plurality of

supportI channels

70', 72', 74 and 76 are provided, the only principal difference being that these pairs of vchannel members are disposed with a greater lateral spacing therebetween for a purpose hereinafter described.

It should also be noted as seen particularly in FIGS. 5 and 6 that the upper ends of the various channel members have stop means 150 associated therewith which is substantially identical with the stop means 102 and 148' provided at the opposite endsv ofthe structure, these stop means in this form ofthe invention simply comprising U-shaped portions extending'fr'o'm thechannel members at opposite endsthereof. n

In this form of the invention, additional protective means in the form of U-Shape members r154 and 156 -are supported upon the opposite ends of the base means of the framework and extend outwardly beyond the stop means as clearly seen in FIGS. 5 and 6. This protective means serves to protect the threads on the corners of cheeses or cones supported by the apparatus.

As seen in FIG. 5, the uppermost cross members 82 and the two cross members 86' disposed immediately therebeneath extend in spanning relationship between the

upright members

54 and 56. On the other hand, the two cross members 86 shown in the lowermost positions in FIG. 5 each consist of two spaced portions which extend between the upright members 54', 56' and the

members

160 and 162 respectively as seen in FIG. 7, these

members

160 and 162 serving to support additional support means hereinafter described.

Similarly, the three lowermost cross members 84 as seen in FIG. 5 extend in spanning relationship between the upright members 50 and 52', while the uppermost cross members and 84 each consist of two spaced portions extending between the upright members 50', 52 and vertical

parallel members

166 and 168 corresponding to the members and 162 provided at the opposite end of the framework.

The lower ends of

members

166 and 168 are rigidly secured to the cross member 84 which is at the central portion of FIG. 5, and the lateral portions of

members

166 and 168 are rigidly affixed to the associated channel members to securely affix all these members in operative relationship with respect to one another. The

members

160 and 162 at the opposite end of the framework have the upper ends thereof rigidly secured to the cross member 86' in the vertical central portion of the framework, and similarly the side portions thereof are rigidly secured to the associated channel members to provide a lightweight strong framework arrangement.

As seen particularly in FIG. 5, additional support means comprises four

elongated support portions

170, 172, 174 and 176 which are inclined in the opposite direction with respect to the channel members 70', 72', 74', 76' and 78 and are further disposed at a greater angle with respect to the horizontal. These

support portions

170, 172, 174 and 176 are rigidly secured to the associated

members

160, 162 and 166, 168 so as to be fixedly secured in the operative relationship illustrated.

As seen most clearly in FIGS. 7 and 8, the support portion includes an intermediate corrugated portion 180 having

tubular portions

182 and 184 formed integrally with the opposite edges thereof. These corrugations provide two substantially V-shaped slots 181 for receiving empty bobbins.

Rod portions 186 disposed within the

tubular portions

182 and 184 join with an integral stop means portion 188 as seen most clearly in FIG. 6, this stop means portion extending outwardly beyond the end of the support portion 170.

Referring to FIG. 7, the support portion 172 is of substantially the same construction as support portion 170', and similar parts have been given the saine reference numerals primed, it being understood that each of the

support portions

170, 172, 174 and 176 are substantially identical, and accordingly, similar reference numerals primed have been applied in connection with-each of the components of the

support portions

172, 174 and 176. As in the lother forms of the invention, the number of support portions or troughs employed may be varied as desired. i

As seen in FIG. 7, cones are illustrated by phantom lines 190 as disposed in various operative positions within the framework and supported by the support portions 120' and 122. It is apparent that the cones may assume various operative relative positions dependent upon the size and configuration of the cones.

With the arrangement as illustrated in FIGS. 5-8 inclusive, empty bobbins may be disposed within the

various support portions

170, 172, 174 and 176 so as to be available at' the right-hand end of the apparatus as seen in FIGS. 5 and 6. Full packages will be placed upon the various support portions associated with channel members 70', 72', 74', 76 and 78' so as to roll downwardly toward the left-hand end of the support means, while the operator picks up the empty bobbins from the lower ends of the additional support means to put them into operative relationship with a machine. The steep angle of the

support portions

170, 172, 174, and 176 ensures that the empty bobbins will slide downwardly therein to be at the right-hand end of the support means.

It is apparent that the opposite end of the support means may be employed when an operator is disposed for example at a twister frame wherein the empty bobbins are placed in the upper ends of

support portions

170, 172, 174 and 176, while full packages are removed from the first-mentioned support portions.

The

second support portions

170, 172, 174 and 176 are so designed as to hold the same number of empty bobbins as the first-mentioned support portions are adapted t support full packages.

Referring now to FIGS. 9-11 inclusive, still another modified form of the invention is illustrated. This strue ture is substantially identical with that shown in FIGS. -8 inclusive, and the same parts have been given the same reference numerals primed.

The only difference in this form of the invention is the provision of reinforcing means at one end of the guide means of the structure whereby said one end of the guide means may serve as steps upon which an operators weight is adapted to be supported, thereby effectively forming a ladder.

As seen in FIGS. 9-11, the first three troughs on the lower end of the outside troughs of the device are provided with reinforcing metal gusset plates indicated by reference numerals 200. These gusset plates are welded in the position illustrated and serve to reinforce the portions 1'48' of the guide means, the outer ends of portions 148 serving as stop means as aforedescribed.

The gusset plates are each welded along an upper edge thereof to a longitudinally extending rod portion of one of the parts 148', while a portion of the vertically extending edge of each of the gusset plates is welded to an adjacent portion of the supporting framework. In the case of the outer gusset plates, they are welded to the upstanding portions 50 and 52', while the inner gusset plates are welded to the cross members'84.

It is apparent that these gusset plates will sufficiently reinforce the end portions of the guide means so that they may support-the weight of an operator whereby these end portions may be used as a ladder when it is desired to load packages into a creel which is considerably above the head. of the operator.

It is apparent from the foregoing that there is provided according to the present invention new and novel movable support means for cones and cheeses and the like which is lightweight, compact and yet strong and rugged in construction, and which will properly feed cones therewithin; and which further enables loading and unloading operations to be carried out at the same time from one end of the support means.

As this invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, the present embodiment is therefore illustrative and not restrictive, and since the scope of the invention is defined by the appended claims,` all changes that fall within the metes and bounds of the claims or that form their functional as well as conjointly cooperative equivalents are therefore intended to be embraced by those claims.
