SPOOL-HOLDER.-

SPECIFICATION forming partof Letters Patent No. 476,883, dated June 14, 1892.

Application filed February 15 1892. Serial No. 421,538. (No model.)

To all whom it concern.-

Be it known that I, MICHAEL G. KUHN, of New York, in the county and Stateof New York, have invented certain new and useful Improvements in Spool-Holders; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates particularly to that class of spool-holding devices which are designed for use in manufacturing establishments where a number of spools are served out to an operator for use upon a sewing or other machine, and are intended to prevent the removal of a spool by the operator While permitting the thread to be drawn off freely until the supply is exhausted.

The objects of the invention are to improve the construction of such devices, to facilitate the removal and replacing of spools by the proper person, to render the device more durabio, and to provideanovel tension device which may be regulated readily by the operator.

The invention consists in the combination and arrangement of parts, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of my improved spool-1'ack, showing the same unlocked and opened for the removal or replacing of spools and showing several spools in position. Fig. 2 is a plan view of the same, showing it closed and locked. Fig. 3 is a similar section of the form in which I prefer to construct the rack.

The base or frame A of the rack is of suitable size and shape to support the desired number of spools, as hereinafter described, and is adapted to be secured to a machine or to rest upon a table. Side plates B B are hinged or pivoted to each side of the base A, and each side plate B has fixed thereto a nu mber of spindles G O, which are adapted to re ceive and support the spools D D. A lockingbar E is connected at one side to one of the side plates and at, the other end is adapted to engage the other of said side plates and to be locked thereto by a locking device F, and a latch G may be allixed to the base to engage the side plates B and hold them in place temporarily until the locking-bar can be secured in place. The spindles C are of such length as to prevent the removal of the spools therefrom when the rack is closed, as shown in Fig. 2. Each spindle O carries a tensionspring l-I, whose pressure upon the spool may be regulated by an adjusting-screw I from the outside of the rack. The spindle is made hollow, as at c, to receive the spring, and is slotted, as at c, to permit the spring to bear upon the spool. In this case the adjusting-screw I is tapped axially into the outer end of the spindle and bears against the end of the spring, which may be bent to give a hearing, as shown. The locking-bar is by preference carried above the spools, as shown in Fig. 3, and is provided with eyes 6 e for the thread in its passage from the spools, thereby making it possible to dispense with independent guides.

As shown in Figs. 1 and 2, pillars K are erected upon the middle line of the base A, and each is formed with an eye It to receive the ends of each pair of opposing spindles 0 when the rack is closed. It is not necessary, however, that the spindles should receive the support of the pillars K, if they are properly secured in the side plates. If it is desirable that the opposing ends of two spindles in alignment should be united, it is preferably accomplished without the use of the pillars by such means as are shown in Fig. 3, wherein a pin L, carried in the end of one spindle, is adapted to enter a recess in the end of the opposing spindle. The pin may be permitted to slide, bein g pressed forward by a spring, as shown.

In the construction shown in Fig. 1 the side plates are represented as connected to the base A by a pivotal joint aat one end. They might, with the same effect, be connected along the side of the base by a hinge-joint a, as shown in Fig. 3.

If it is desired to provide for the support of a single row of spools, the base A may be made of a corresponding width, and a single plate, either fixed or movable, may serve as an abutment for the ends of the spools and as a point of attachment for the locking-bar.

I am aware that a spool-holder comprising a frame, a longitudinally-extending partition havingtransversely-projectingspool-spindles, sides fitted to slide laterally on the frame, and a locking device to retain the movable sides in position has been shown in a patent bearing date earlier than my application; but I do not claim such construction herein. By hinging the side plates upon the base instead of providing rods upon which they may slide I have produced a spool-holder which is simpler in construction, more easily and cheaply manufactured, and more readily manipulated for the purpose of removing and replacing spools.

I claim as my invention 1. The combination of a fixed spool-holding spindle, hollow and slotted, as described, a support therefor, a laterally-yielding spring placed longitudinally Within said spindle, and an adj listing-screw tapped into said spindle axially and adapted to bear against the end of said spring, substantially as shown and described.

2. In a spool-holder, the combination of a base, a side plate supported by said base, but movable with respect thereto, a spool-supporting spindle fixed to said side plate, said spin- (lle being hollow and slotted, a laterally-yielding spring placed longitudinally within said spindle, and an adjusting-screw adapted to bear against the end of said spring, substantially as shown and described.

'3. In a spool-holder, the combination of a base, side plates having a hinged or pivotal connectionwith said base, spool-supporting spindles fixed to said side plates, and a locking-bar connected with one of said side plates and adapted to engage the other, said lockingbar being formed with guide-eyes for the thread from the spools, substantially as shown and described.

4. In a spool-holder, the combination of a base, side plates having a hinged or pivotal connection with said base, spool-supporting spindles fixed to said side plates, the corresponding spindles on the opposing plates being in alignment, a pin carried by one of said corresponding spindles and adapted to enter a recess in the other, and means to lock the plates in position, substantially as shown and described.

5. In a spool-holder, the combination of a base, side plates having hinged or pivoted connection with opposite sides of said base, spo0l-sn pportin g spindles fixed to both of said side plates, the corresponding spindles on the opposing plates being in alignment and adapted to engage and support each other at their free ends, and means to lock the plates in position, substantially as shown and de scribed.

In testimony whereof I have signed my name to this specification in the presence of two subscribin g witnesses.
