UNITED STATES MILTON ZUBEBI, OF NEW YORK, N. Y.

MULTIEPLE-SPOOL HOLDER.

Application filed. August 12, 1922.

T 0 (a l whom it may concern:

Be it known that I, MILTON ZUBER, a citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful. Improvements in Multiple-Spool Holders, of which the following is a specification.

My present invention relates primarily to multiple spool holders, and although it has its preferred application in the textile industry for holding a plurality of spools of thread in convenient position against loss and for convenient access at will to the thread of any selected spool, many of the preferred features are applicable in any relation where access is desired at will to any one of a plurality of reels, spools or other magazines of thread, wire or other material.

It is an object of the invention to provide a spool holder of particularly simple rugged and inexpensive construction for supporting spools without danger of entangling the threads or other material thereon and which shall permit access readily and conveniently to any selected spool.

Another object is to provide a holder of the above type which shall be suited to mounting any desired number of spools in position and in which the spools can be readily removed or replaced when exhausted.

In a preferred embodiment, the spool holder comprises a built up construction, including a plurality of spool. support bracket arms mounted upon a support, the spool held at one end by each arm being maintained in position by the coaction of one of the other arms against removal when the device is locked.

In a preferred specific embodiment, the bracket arm members are telescoped over a cylindrical support rod and successive arms are keyed with respect to each other, the arms extending outward from the support rod in a plurality of groups, each group in a common plane, the telescoping bracket portions for each group constituting spacers between successive arms in each other group.

In a preferred inexpensive construction, the support rod is a simple vertical tube, the bracket members are composed of T fittings telescoped over said tube and the bracket arms are pipe elements fitting into the stems of the T fittings and flattened at their outer ends for support of the spools. A look is Serial No. 581,311.

provided above the uppermost of the bracketarms to prevent separation of the keyed connection between successive arms, so that the spool members will all be locked in position and may be released upon opening of the lock member to raise any bracket arm for separation thereof with respect to the associated spool therebelow which can then be removed for replacement.

In the accompanying drawings in which is shown one of various possible embodiments of the several. features of the invention,

Fig. 1 is a side elevation with parts broken away of a preferred embodiment of the invention, shown in section, and:

Fig. 2 is a plan view thereof.

Referring now to the drawings, I have shown a spool holder comprising a base, pedestal or support 1 preferably. provided with lugs 2 by which it may be screwed to a table, bench or other support. Preferably threaded into the upper end of the base is a support tube or rod 3. In the preferred specific embodiment, a plurality of fittings 1, 5, 6 and 7, 10, 11 and 12, are telescoped over the support rod, each fitting having a key 8 integral therewith in the lower edge thereof fitting into a corresponding keyway 9 in the upper edge of the adjacent fitting immediately therebelow. Fittings 4, 5, 6 and 7 in the specific embodiment are shown as ordinary T fittings, within the stems 13 of which are threaded and secured short lengths of pipe 14 flattened as at 15 near the outer ends thereof to constitute spool supporting platforms. The telescoped fitting 5 which extends toward the left together with the collar fitting 10 constitute a spacer between fittings 4 and 6 extending toward the right, to afford the required gap between the free ends of arms 14 and 14 for accommodating a spool as at 16. Similarly the telescoped fitting 6 with collar fitting 10 constitute a spacer between fittings 5 and 7 for accommodating a spool (not shown) therebetween. Each spool. is preferably mounted upon a in, axle or rod 17 having a head 18 pressed lnto a corresponding aperture 19 on the fiattened portion 15 of the arm therebelow and extends upward therefrom, the upper free tapered end 20 of each pin extending in the assembled construction into a corresponding depression 21 in the lower end of the in head immediately thereabove, Spool pins of the type described, it will be seen, are secured into the arms of fittings 4, 5, 6 and 7 in the specific embodiment shown.

A special crown fitting 12 is telesooped over the upper end of the rod and has a key connection 22 with the spacer collar 11 immediately therebelow. Crown fitting 12 has pipe stem. extensions 23 similar to those heretofore described, affording sockets 24 at their ends for-coaction with the upper ends of the spool pins 17.

The device described is releasably locked by a lock cap 25 telescoped over the free end of the support rod above the crown fitting 12, the cross pin 26 through the support rod extending into an elongated slot 27 in the cap to limit the elevation thereof. The cap is normally retained in its lowermost or locked position by a spring latch. member 28 fitting into corresponding notches 29 in the inner wall of the support tube near the upper end thereof, said latches being releasable by means of a key (not shown) insertable through a keyhole 30.

It will be seen that the multiple spool support described is of particularly simple and inexpensive construction. The keys and 'keyways are readily produced by a simple 'milling operation upon standard T fittings and. theflattening of the spool supporting rod eirtensions is readily effected by means of a punch press operation. It will be read ily seen that by inversion of a T fitting for coaction of its keys with a corresponding keywayof an adjacent identical fitting. the arms of said two fittings will extend as shown at 4:, 5 in opposite directions from the support rod, as desired.

The spool holder, it will be seen, is a builtup construction assembled by telescoping the successive identical T fittings and spacer collars over the support rod, applying the locking cap and as a final operation, applying the lock pin 26 in position. To charge the multiple spool holder, it is merely necessary to release the latch 28, elevate the cap to the limit allowed by the slot 26 which permits elevation of any one of the fittings to release its keyway connection to those therebelow, to permit ready displacement thereof about the support rod 3 as an axis to expose the upper end of the spool anchoring pin immediately :therebelow. By this means, it will be seen that a spool can read ily he slipped over each or any required number of the support axles, whereupon, the bracket arm immediately thereabove can be restoredto its original position and when they have all been restored, the cap 25 can be snapped back to locked position. If all of the keys are not in proper coaction with their keyways the-locking cap is in .a posit1on higher than raised locking position. It

will therefore be seen that the locking cap cannot be snapped to locking'position until.

until lock 28 is opened by an authorized person in possession of a key.

In use, the operator grasps the thread on any selected spool and draws thereon in the usual manner for sewing either by machine or by hand. Upon drawing on the thread,

the tension thereon will effect rotation of the entire assembly of bracket, support arms and spools about the spool support 3 as an axis to bring the selected spool into most convenient position relative to the operator, without danger of entangling with respect to the threads on the other spools,. which maintain their position relative to the selected spool.

In order to prevent spinning of any spool about its axle, it is preferred to provide dished springs 31 encircling axle pins 17, to exert friction or braking force upon" each spool, by forcing it against the bracket arin immediately thereabove. By this operation, friction will be exerted upon the spool, such that when the tension is applied to the thread thereof, the spool will firstbe drawn. together with the entire assembly of sleeve fittings and projecting arms to the position in which the tensed thread is in the plane of the support rod. By reason of the braking effect of springs 31. tension suddenly applied to the thread will not cause spinning of the spool about the axle and will avoid any consequent danger of entangling the thread. y

When a spool is to be replaced after exhaustion thereof or for substitution of different type or color of thread. the opera tor opens the look 28, raises the cap 25, raises the arm 14 immediately above the exhausted spool. thereby releasing the free end of the corresponding spool support axle 17, and after laterally shifting the arm about the support rod. he can remove the spool from its pin. The operation of re placement, resetting and locking the'devioe will. be obvious from the foregoing.

The embodiment shown in the drawings is merely a simple preferred form of the in vention. It will, of course, be understood that by providing additional fittings and a longer support rod, the spool holder may be i built up to any elevation desired. It will be moreover understood that the bracket arms may be extended in three or more planes at corresponding angles. It will also be apparent that, if desired. the entire group of bracket arms and their telescoping portions may be formed as a single integral sleeve about the support rod or may be formed in rious objects of the invention and is well suited to meet requirements of practical use.

As many changes could be made in the above construction and many apparently widely different embodiments of this inven tion could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
