Pin rail assemblies spanfthe posts. Each pin raiLas'sembIy includes a pair of pin rails permanently interconnected at each end of the assembly by.a plate. The pin rail assemblymay be assembledwiththe posts by being'lowered thereonto as a unit and may berernoved 'frorn the posts by being raised therefrom as a unit.

3,409,141 Patented Nov. 5, 1968 bers aforesaid are connected together to provide a rigid horizontally extending frame supported on a pair of swivel casters and 32 disposed respectively at the front and rear thereof and a pair of fixed casters 34 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 40 is aifixed to the mobile base frame 10 by means of an angle bracket 50.

s Theframework 38 also comprises a plurality of vertically spaced assemblies 54, each carrying pins adapted for mounting a group of pirns. Each assembly includes it 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 top and bot- 1 tom with turned in portions struck therefrom to form yam,'as for example, rom" one part of a 'mni to another. I v

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 time. Other objects offthelinvention will become. apparent when the following descriptiontis: read with reference to the accompanying drawings, in which: y FIGURE 1 is a frontview of a pirn truck constructed inaccordance with the invention;, V I 1 FIGURE 2 is a .side,view of the pirn truck shown FIGUREI; j p f.

FIGURE'lS isa section through an adapter shown in phantom in FIGURE 13/ enlarged section Oil line vrn vtn tongues 68 slidably fitted between the flanges 44 of the associated post 40. Each plate 66 rigidly secures together the associated end portions of the members 56 and positionsthe members 56 with their webs 58 disposed in planes which converge upwardly, as shown. Each plate is provided with a hole 72, and projected through a lock washer 74 and the hole 72 is a screw 76 threaded into anut 78. The nut is of a depth slightly less than the clear distance between the inturned portions 48 of the flanges I k 44, and diagonally disposed corners of the nut are yarn packages of a different. size and number at another rounded, as at 79. One face of the nut is provided with laterally spaced parallel grooves 81 which receives marginal areas of the inturned portions 48 of the flanges-44. The bottom of each groove 81 is provided with a series of transversely extending teeth 84 which firmly engage the opposed edge of the associated inturned portion 48.

Each member 56 mounts a plurality of pins 80, each of which has a. threaded portion 82 extending from a flange 85 at the base thereof and between the flanges 60, of the member 56. The portion 82 is threaded into a nut 86 non-turnably captured between the flanges 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. The body of the pin is tubular and tapered from a large diameter at the base of the pin to a smaller diameter at the opposite extremity thereof. Fitted over the main body of the pin, next to the flange 85, is a collar 87. The pin 80 in its entirety, including the nut 86, preferably is made of nylon.

On each side of the truck is a tubular handle bar 88 which is rectangular in shape. Referring to FIGURES 4 to 6, each bar 88 is secured to the associated post 40 by a pair of clips 90. Each clip has a semicircular main Referring to the drawings, a pirn'truck constructed body part extending about the tube and terminating at one end in a portion 92 extending tangentially therefrom. At the opposite end is an ear 94 disposed at right angles to the portion 92. The portion 92 is recessed on opposite sides, as at 96, to provide shoulders 98. The recesses 96 accommodate the flanges 44 of the post 40 and the shoulders 98 are opposed respectively to the inturned portions 48 of the flanges 44. The clip is adjustably secured to the post 40 by a bolt 100 extending through the car 94 and threaded into a nut 78.

In the use of the truck, pirns or bobbins of yarn, designated P, 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 about its axis in a 3 direction to loosen its grip on the channel member 56. Then the pin 80 and nut 86 are shifted as a unit to the desired position, whereupon the pin 80 is turned about its 'axis in the opposite direction to retighten the connection. Each assembly 54 is adjustably fixed in position. To shift the assembly 54 vertically, the screws 76 are turned out sufficiently to loosen the grip of the nuts 78 on the posts 40. Then the entire assembly 54 is raised or lowered as desired, whereupon the screws 76 are turned in again to retighten the connections. It will be noted that one or more of the assemblies 54 may be conveniently removed as a unit from the framework 38 or added thereto to accommodate different sizes of yarn packages and different numbers thereof. For example, as illustrated, nine assemblies 54 are employed. Each assembly mounts ten yarn packages in all. This arrangement accommodates a total of ninety yarn packages. However, if desired, nine assemblies 54 may be employed, with each assembly mounting eight comparatively large yarn packages. Thus a total of seventy-two comparatively large 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. 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.

For example, referring particularly to FIGURE 10, pins 80 may be removed and replaced by pins 102, which are similar in every respect to pins 80, except that the collar 87 is omitted. A package of yarn (not shown) may be mounted directly upon the pin 102. On the other hand, the cylindrical core 103 of a yarn package P may be fitted over an adapter 104, which in turn is mounted upon the pin. The adapter is provided with a centrally disposed annulus 106 at the outer end thereof fitted snugly over the tapered body of the pin. Extending radially outwardly from the annulus 106 are a pair of diametrically opposite wings 108 and a pair of diametrically opposite wings 109 equally spaced about the annulus and extending therefrom toward the base of the pin. Intermediate the opposite ends of the adapter are a pair of axially spaced webs 110 and 112 interconnecting the wings 108 and 109. The pin extends freely through the webs. The portions of the wings 109 extending rearwardly from the web 112 about the flange 85, while the portions of the wings 108 extending rearwardly from the web 112 are shaped, as at 114, to snap over the flange 85 of the pin. The adapter 104 preferably is made of nylon.

Referring particularly to FIGURE 11, the adapter 104 may be replaced by an adapter 116 capable of mounting the package P The adapter 116 is provided with an axially extending tapered tubular sleeve 118 which fits snugly over the tapered body of the pin 102. Equally spaced about the sleeve 118 and extending longitudinally thereof are a pair of diametrically opposite wings 120 and a pair of diametrically opposite wings 121 equally spaced about the sleeve 118. Intermediate the opposite ends of the adapter are a pair of axially spaced webs 122 and 124 interconnecting the sleeve 118 and the wings 120. The portions of the wings 121 extending rearwardly from the web 124 are adapted to abut the flange 85, while the portions of the wings 120 extending rearwardly from the web 124 are' adapted, as at 126, to snap over the flange 85 of the pin 102. The adapter 116 preferably is made of nylon.

Referring particularly to FIGURE 12, the pin 80 may be removed and replaced by a pin 128. Threaded over the base end of the pin is a nut 130. Underlying the nut is a flat washer 132 and underlying the flat washer is a cylindrical spacer 134 preferably made of nylon. The washer is seated upon the flanges 60 of the associated member 56, and the spacer extends freely between said flanges. The end of the pin extending beyond the spacer is threaded into a nut 78. Extending about the washer is the axially extending cylindrical portion of a flange 136. The pin mounts a package of yarn P wound on a spool 138 fitted over the pin. The spool is provided at one end with a base flange 140 seated against the flange 136 and at the opposite end with a flange 142.

Referring to FIGURES 13 to 15, the pin 80 maybe removed and replaced by a pin 144 provided with a cylindrical main body 146. Equally spaced about the -cylindrical body and extending longitudinally thereof are four wings 148 terminating at the base of the pin in a web 150. Extending axially from the web 150 is an externally threaded tubular portion 151 by means of which the pin may be adjustably secured to the member 56, with its web 150 seated against the flanges thereof. The wings 148 are stepped to provide shoulders 152 of minor radial depth, 154 and 156 of intermediate radial depth and 158 of maximum radial depth. The pin 144 mounts a package of yarn P wound on a spool 160 fitted over the pin and provided with an insert 162 fitted over the outer end portion of the pin. The inner end portion of the spool 'fits over the shoulders 158.

An adapter 164 having a'centrally apertured wall 166, an axially extending inner flange 168 and an axially extending outer flange 170 may be fitted over the end of the pin 144. The outside diameter of the adapter 164 corresponds to the distance between oppositely facing shoulders 154 so that the cylindrical spool of a yarn package (not shown) may be fitted over said shoulders and adapter. The pin 144 and the adapter 164 preferably are made of nylon.

In mounting an assembly 54 on the posts 40, the assembly is lowered over the posts 40 to the desired position thereof. The nuts 78 are then held with their grooves 81 extending horizontally, and then inserted between the flanges 44 of the posts. After positioning the nuts with their threaded openings in registry with the openings 72 in the plates 66, the bolts 76 are projected through the lock washers 74 and the openings 72 and threaded into the nuts 78. As a screw 76 is turned into the nut 78, the nut turns till the corners that are not rounded engage the flanges 44 of the posts. When this occurs, the grooves 81 are in registry with the edges of the inturned portions 48 of the flanges 44. When the screw 76 is threaded fully into the nut 78, the teeth 84 at the bottom of the grooves 81 are firmly engaged with the edges of the inturned portions 48 of the flanges 44. The vertical position of the assembly 54 may be adjusted by loosening the screws 76, moving the assembly as a unit to the desired position thereof and then retightening the screw 76. It will be noted that above the base frame 10, the posts are tied together solely by the assemblies 54. Therefore, the assemblies 54 may be assembled with the posts 40 by lowering them thereonto each as a unit, and may be removed from the posts 40 by raising them each as a unit. In other words, it is not necessary to disassemble a frame 54 in order to assemble it with or remove it from the posts 40.

In addition, it will be noted that the members 56 are open ended channel members. Thus the number of pins mounted thereon may be readily varied'by slipping the pins on and off endwise.

It is unnecessary to provide the specific channel iron construction for the adjustable pirn rails 56' for it will be apparent to those skilled in the art that manydiiferent shapes 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. v
