DOMENICO AUDINO, OF BUFFAIJQ' NEW YORK SPOOL RACK Application led December 4, 1929. Serial No. 411,447.

cessive garments or portions of a garmentvv being sewed 1n a glven machin-e, and 1t 1s desirable to have the different spools of silk accessibly disposed, :so that the operator can quickly supply the sewing machine'with the required thread. Such a rack also prevents the threads from being soiled or tangling,

and by providing means forv locking the` spools in the rack, prevents the unauthorized detachment of the spools therefrom, avoiding loss or theft.

The objects of the invention are to provide an improved spool holder or rack of simple and rugged construction vformed to support a relatively large number of spools in compact order while occupying itself a relatively small space; also to provide a rack or support of this character on which a plurality of spools can be mounted, so that anyone of the spools can be moved to a common' operative position from whence uniform delivery of the thread can be had; also to provide an improved rack in whichthe spools are supported side by side, and which permits collective movement of all of the spools thereon to enable any spool to be removed for replacement by another spool, or a selected spool to be brought to a predetermined operative position; also to construct a spool rack in which the spools are arranged side by side in a row, and which permits one or more selected spools to be shifted out of said row to an operative position; and also to provide a spool rack having a plura'lity'of individual spool spindles and a guldeway in which the spindles are loosely., mounted 12o-move along the same, and'v to provideV means permitting the spindles to be shifted out of said guideway for placing a selected spool in operative position.

Other objects are to provide a spool rack having improved and simplified means for locking or securing the spools in place on the rack and which means can be readily actuated Vto permit insertion or removaly of the spools; also to provide a rack having individual spool spindles of novel construction` for rotatably supporting the spools; also to provide the rack with a series of spool spindles which, while being all of the same size 'and construction, are adapted to support spools of different lengths; and alsoto providetherackwith spindles for this purpose which are constructed so that the operator can readily see the size and color numbers or designationsof the thread on the ends of the spools while in place on therack.

l Other objects are to -construct a spool rack in which a number of spools are loosely mounted, vand which permits two or more spools to be shifted and supported in operative positions whereby a corresponding number of threads maybe simultaneously delivered todiderent points; and also to improve spool racks in the other respects hereinafter setforth and claimed.

In the illustrated embodiment o'f the invention, the improved spool rack comprises a pair of spaced frame members 10 rigidly secured together by meansA of a plurality of spacing rods or members 11 of suitable construction.

These frame members 10 are preferably in the form of narrow upright plates or castings, each of which is provided with an inwardly facing peripheral Ouide groove or channel 12, preferably of endless or continuous form including opposite, relatively elongated upright parallel side portions 13 connected by upper and lower transverse end portions 14 of semi-circular or other form.

Means are provided for mounting a plurality of spools A on the rack, so that they extend transversely of and are retained between the frame members 10 with their axes disposed horizontally and parallel, one with the other, as shown in Figuresl-S.

For this purpose, eachspool A is mounted on an individual spindle or support B of such length and construction that its opposite ends b form journals extending into the opposed channels 12 on the frame members, and are slidable lengthwise thereof.

Preferably each of the spindles B is provided adjacent its ends or journals b With circular enlargements, rollers, or spool retaining parts 15, so spaced that when a plurality of these spindles are mounted on the rack, they will be disposed side by side or in a row with the peripheries of said rollers 15 in contact, with the spools A disposed between said flanges. Y

It will be seen from the foregoing that when a plurality of the spindles B with the spools A are mounted on the rack, the entire series of spindles and spools may be shifted lengthwise along or around the guideways 12, so as to bring any desired spool toa required position.

Preferably the rack is provided with means enabling any selected spool shifted in this manner to be supported in a common operative position. In the construction shown for this purpose, the frame members or uprights 10 are provided with a pair of opposed projecting arms 2O each having formed therein a lateral guide portion or channel 21 which communicates with the guide channels 12 in said uprights, and are formed to receive the journals Z) of a spool spindle B. When, therefore, it is desired to place a particular spool into operative position, this spool may. be grasped by the operative and by exerting pressure thereon in a direction lengthwise of the guide channels 12, the remaining spools A on the rack may be displaced, their spindles B sliding along said guideway until the selected spool is brought opposite the lateral arms 20, whereupon the journals Z) of its spindle B may be guided into the lateral channel portions 21 in said arms.

The outer ends of the lateral guide channels are preferably formed with depending portions or seats 22 for receiving and rotatably supporting the ends of a spindle, so that a selected spool A can be maintained in an operative position and prevented from shifting back into the guideways 12 of the raclr while in use.

While one thread is being delivered to and used on a sewing machine, for example, it is desirable that another thread be delivered to and wound on a bobbin by the same machine, or for any other desired use.

For this purpose the spool rack can be provided with one or more additional pairs of opposed lateral projections 25, similar to the projections 20, and which are provided with channel portions 26 communicating with the guide channels 12 and terminating in seats 27. By this arrangement, one or more spools A mounted on the individual spindles B, can be selected from the group of spools on the rack, shifted to and operatively supported in said seats.

In order to guide and tension the thread or threads being delivered for use, the spool rack may be provided with suitable guide and tension devices, preferably associated with each pair of lateral projections 20 or 25. Two of such devices are shown for this purpose, each of which comprises a transversely extending bail ormember 28 having an intermediate transverse portion 29 and opposite side arms 30. The opposite ends of the device are loosely pivoted in holes 31 in said laterally projecting arms, and preferably above the seats 22 or 27. The transverse portion 29 is provided with a small hole 32 through which the thread from the adjacent operatively mounted spool is passed. The transverse portion 29 of the bail or device is located at some distanceV from its pivotal connections 30 so that the weight of the member acts to tension the thread.

Any suitable means may be provided to permit the spools A, each mounted on their individual supports or spindles B, to be placedin or removed from the spool rack, and securely retainedA against unauthorized removal or displacement therefrom. For example, in the -construction shown in Figs. 2,

4 and 5 one of the frame members 10 is divided transversely near its upper ends, as vat v35, so as to provide a movable portion 36 vertically movable bolt or latch member 39,

see Fig. 4, which, when the movable member is in upright operative position, enters a recess 4() therein, and prevents the same from swinging about its hinge relatively to the stationary part. The upper portion 14 of the guide channel 12 is formed in said movable frame portion 36, and is continuous with the upright side portions 13 ofV this guide channel in the stationary part of the frame member 10. Thus, by unlocking the movable member 36 and swinging the same about its hinge 37, as shown in Fig. 5, the spool spindles with or without the spools thereon can'be readily inserted into or removed from the guide channels 12 of the rack.

In the modified construction shown in Figs. 9-12, the upright side members 10a are formed or provided with projections at their upper ends. Eachr of these projections is formed with a groove or channel 51 extending from the outer edge thereof to and in communication with the guide grooves 14a in which the spool supports B are arranged.

The'grooves or channels 51 are normally obstructed by a transversely extending locking rod or member 52, one end of which is received in a closed seat 53 in one of the members 10a, while the other end is received in a hole 54 extending through the other member 100i.- The rod or locking member 52 when in its locking position, as shown in Figs. 9 and 11 in which itextends crosswiseV of the spool holder eifectually prevents the journals of the spool holders from being moved out of the lateral grooves or channels 51.

In order to retain the rod 52 in its spool holder retaining or locking position, a suitable lock 56 is riveted or otherwise rigidly arranged in a cavity 57 in one of the members 10a so that the bolt 58 thereof, when projected, can be engaged in a transverse notch 59 in the then adjacent end of saidrod 52, thus preventing endwise movement of the rod. The cylinder 60 of the lock extends through a hole in a removable cover plate 61 so as to be accessible for actuating the bolt 58. By actuating the lock 56 the-bolt 58 thereof may be retracted from the notch 59, thus permitting the locking rod 52 to be moved endwise to the position shown in Fig. 10,' in

which position the lateral groove or channel portions 51 are unobstructed, thus permitting the spool holders B to be removedor inserted.

In order to maintainnotch 59 ofthe rodl 52 in operative relation to the bolt 58of the lock, the rod may be provided with a lengthwise groove 62 into which a fixed pin or projection 63 on the spool rack extends. The inner end of the locking rod 52 may be provided with a projection or pin 65 disposed in the slot 62 thereof and which, when the rod is moved to its unlocking position, engages the stationary pin 63 to prevent the rod from being entirely removed. Means of any other suitable construction may Vbe provided for locking the spool holder to retain the spool supports in place thereon and prevent unauthorized removal of the Vspool supports or theft of the spools.

Since spools of diiferent kinds and sizes of thread often vary in length, it is desirable to form the supports or spindles B so that such different sized spools can be mounted thereon, while at the same time permit-- ting the rollers or fianges 15 of said spindles to be retained in alinement so as to contact one with another, as before described. For this purpose, and to enable the spools to be placed on the spindles between the rollers 15 thereof, each spindle B, see Fig. 7, is made in two sections, one of which includes an axial tube or sleeve 40a to which the hub 41 of one of the rollers or iianges 15 is rigidly secured with an end of said sleeve projecting beyond the roller to provide one journal b of the spindle. The other part of the spindle comprises an axial rod or portion 42 of a diameter such that it will telescope with said sleeve 40a. To this rod 42 is secured the hub 43 of the other roller 15 of the spindle with a part 100 projecting outwardly to form the other ournal Then the two parts are telescoped, one within the other, the roller 15 on the rod 42 abuts against the open inner end of the sleeve 40a. Thus, the intermediate portion 105 of the sleeve 40a, which is of the same length in all of the sleeves, acts as a spacer preventing inward relative movement of the rollers 15 of each spindle, while the rollers 15 in turn are prevented from outward movement, when 110 mounted on the rack, by engagement with the inner faces of the frame members 10. These rollers being disposed between the ends of the spools and said members 10 act to hold the spools out of contact with the latter. 115 Thus, spools A of any length within the limits of the sleeves 40a can be accommodated on the spindles B, see Fig. 1, by separating the two parts of a spindle and inserting the. tubular portion 40a into the hole in a spool A, and then passing the other portion 42 into said sleeve from the opposite end of said spool.

Also by forming the spindles or supports B with the rollers 15 disposed close to the frame 125 members 10, the spindles are prevented from being turned obliquely across the space between said frame members to a position where they might be forced out of the guideways as might` be the case, for example, were a dles B are made of somewhat greater diameter than that of the largest spool ordinarily used on the spool rack. Consequently, the spools will be held out of Contact one with another with their axis uniformly spaced,

' regardless ot varying diameters and lengths ot the spools, and the group otl spindles on the rack can roll one on another when shifted along the guideway. in this way the desired spools can be selected and brought to operative position with little effort due to the rolling action of the spindles upon each other, particularly when moving transversely across the upper or lower ends of the rack.

It is often the case that when using spool raclrs or supports of this character that a number ot diiterent threads varying only slightly in color and size are present on the rack at the same time, so that it is diilicult for the operator to select the correct thread or 'threads toi' the work in hand. 1t is desii-able, therefore, to provide moans enabling the operator to be able to positively identity the thread on each spool A on the rack as by the size and color numbers or other designations usuaily present on the ends of the spools. For this purpose, one or both rollers or flanges l5 ot each spindle B is made ot open or skeleton form, or is otherwise constructed to provide one or more sight openings 45. Thus, bv merely rotating a spindle or spoel, the size andcolor numbers on the end of the latter can he brought to view through an opening 45, outwardly oi the edges of the uprights l0, as shown in Figs. 2 and 8.
