N.C., assignors to Cocker Machine & Foundry Company, Gastonia, N.C., a corporation of North Carolina Filed July 15, 1966, Ser. No. 565,595 6 Claims. (Cl. 211-13) ABSTRACT OF THE DISCLOSURE The upper end portions of laterally spaced posts are interconnected by a horizontally extending member to form a framework of inverted U-shape carried by a mobile base. Pin rail assemblies span the posts. Each pin rail assembly includes a pair of pin rails interconnected at each end of the assembly by a plate. The pin rails and the plates may be quickly assembled for being mounted upon the framework and quickly disassembled for removal from the framework.

This invention relates generally to manually propelled industrial trucks and particularly to improvements in such trucks used for transporting pirns or bobbins of textile yarn, as, for example, from one part of a mill to another.

An important object of the invention is to provide a pirn truck which has enhanced flexibility in use.

Another object is to provide such a truck with mounting assemblies readily adjustable for accommodating yarn packages of a given size and number at one time and yarn packages of a different size and number at another time.

Other objects of the invention will become apparent when the following description is read with reference to the accompanying drawings, in which:

FIGURE 1 is a front view of a pirn truck constructed in accordance with the invention;

FIGURE 2 is a side view of the pirn truck shown in FIGURE 1;

FIGURE 3 is a section on line IIIIII in FIGURE 2;

FIGURE 4 is an enlarged section on line IVIV in FIGURE 2;

FIGURE 5 is an enlarged section on line VV in FIGURE 1; and

FIGURE 6 is an exploded perspective view of an as sembly for mounting a group of pirn mounting pins.

Referring to the drawings, a pirn truck constructed in accordance with the invention includes a dirigible mobile base in the form of a frame, generally designated 10. The frame 10 comprises longitudinally extending opposite side members 12 and 14, transversely extending front and rear members 16 and 18 and transversely extending intermediate members 20, 22, 24 and 26. A centrally disposed lon- =gitudinally extending member 28 overlies the members 16, 20, 22, 24, 26 and 18. The members aforesaid are connected together to provide a rigid horizontally extending frame supported on a pair of swivel casters 30 and 32 disposed respectively at the front and rear thereof and a pair of fixed casters 3-4 and 36 disposed respectively on opposite sides thereof.

Extending upwardly from the mobile base frame 10 is an open framework, generally designated 38. The framework comprises a pair of laterally spaced posts 40, each provided with a web 42 and a pair of flanges 44. Each flange 44 is turned inwardly toward the other, as at 46, and then turned toward the web, as at 48. The lower extremity of each post is aflixed to the mobile base frame 10 by means of an angle bracket 50. The upper end portions of the posts 40 are interconnected by an inverted T -bar 52.

The framework 38 also comprises a plurality of vertically spaced assemblies 54, each carrying pins adapted "ice for mounting a group of pirns. Each assembly includes a pair of channel members 56, and each member 56 is provided with a web 58 and a pair of flanges 60. Each flange 60 is turned inwardly toward the other, as at 62, and then turned toward the web, as at 64. At each end of the assembly 54 is a plate 66 provided with a pair of vertically spaced lugs 68 slidably fitting between the flanges 48 of the associated post 40, and with two pairs of vertically spaced lugs 70 respectively fitting into corresponding ends of the channel members 56 and disposed to hold the channel members in inclined positions, as shown. The plate 66 is provided with a hole 72, and projected through the hole and through a flat washer 74 is a screw 76 threaded into a nut 78 non-turnably captured between the flanges 44 of the post 40. The portions 48 of the flanges 44 overlie the nut 78 and secure the same against being pulled out from between the flanges 44. Each member 56- is provided with a group of pins 80, each of which has a screw 82 extending from the base thereof and through a flat washer 84 and between the flanges 60 of the member 56. The screw 82 is threaded into a nut 86 non-turnably captured between the flanges 60 of the member 56. The portions 64 of the flanges 60 overlie the nut 86 and secure the same against being pulled out from between the flanges 60. It will be noted that the pins are inclined at an angle of approximately fifteen degrees relative to the horizontal.

On each side of the truck is a bumper bar 88 of inverted U-shape. The lower extremities of the legs of the bumper bar, designated 90, are rigidly secured to the mobile base frame 10. Referring to FIGURE 4, a fitting 94 provided with vertically spaced lugs 96 fitting between the flanges 44 of the post 40 has the leg connecting part 92 of the bumper bar extending therethrough. A screw 98 extends through the fitting 94 and the leg connecting part 92 of the bumper bar and is threaded into a nut 100 non-turnably captured between the flanges 44 of the post 40.

In the use of the truck, pirns or bobbins of yarn, designated I, are fitted over the pins 80, thus affording a bank of pirns or bobbins of yarn P on each side of the framework 38. Each pin is adjustably fixed in position. To shift the pin horizontally, it is turned in a direction to loosen its grip on the channel member 56. Then the pin =80, screw 84, Washer 82 and nut 86 are shifted as a unit to the desired position, whereupon the pin 80 is turned in the opposite direction to retighten the connection. Each assembly 54 is adjnstably fixed in position. To shift the assembly 54 vertically, the screws 76 are turned out sufliciently to loosen the grip of the plates 66 on the posts 40. Then the entire assembly 54 is raised or lowered as desired, whereupon the connections are retightened. It will be noted that one or more of the assemblies 54 may be conveniently removed from the framework 38 or added thereto to accommodate different sizes of yarn packages and different numbers thereof. For example, as illustrated, eight assemblies 54 are employed. Alternate assemblies mount four yarn packages in all, while intervening assemblies mount six yarn packages in all. This arrangement accommodates a total of 40 comparatively large yarn packages. However, if desired, nine assemblies 54 may be employed, with each assembly mounting eight comparatively small yarn packages. Thus a total of seventy-two comparatively small yarn packages may be accommodated. In addition, the arrangement of pins 80 on one side of the framework may be different than that on the other side to suit requirements of the work. Furthermore, pins that are in use may be removed readily and pins different in size and/or shape may be substituted therefor to carry yarn packaged differently.

The bumper bars 88 are provided to protect the pirns from injury in the event that the truck runs into some obstruction, and to brace the framework 38 in its upright position.

It is unnecessary to provide the specific channel iron construction for the adjustable pirn holders for it will be apparent to those skilled in the art that many variations may be substituted without departing from the spirit of this invention. In addition, equivalent elements may be substituted for those specifically shown in the drawings and described herein, parts may be reversed, and certain features of the invention may be used independently of other features, all without departing from the scope of the invention as defined in the appended claims.
