1S ll. LEWY, OF NEW YORK, Y., ASSIGNOR TO CHARLES H. LEVY AND MEYER JONASSON, OF SAME PLACE.

SPECIFICATON forming part of Let-ters Patent No. 448,528, dated March 17, 1891.

Application tiled October 18, 1890. Serial No. 368,609. (No model.)

To @ZZ whom z'f may concern:

Be it known that I, CHARLES H. LEWY, a subject of the Emperor of Germany, at present residing in the city of New York, in the county and State of New York, United States ol' America, have invented a new and useful Improvement in Spool-Holders, of which the following isa full, clear, and exact description.

My invention relates to an improved spoolholder, and has for its object to provide a ro tatable table adapted to con tain a n iiinber of spools, each capable of independent rotation, and also to provide a means whereby the spools, while free to turn, cannot be removed from the table except by a person or persons possessing the key of the locking device einployed in connection with the spool-holder.

A further object of the invention is to provide a means for expeditiously and conveniently removing1 empty spools from the table and substituting therefor filled spools, and to construct a device in a simple, durable, and economic manner, capable of being inanipulated successfully by any person ot' ordinary intelligence.

The invention consists. in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters ot reference indicate corresponding parts in all the views.

Figurel is a side elevation of theiinprovement with parts in section and as applied .to the arm of a sewing-machine. Fig. 2 is ai1inverted sectional plan view of the saine on the lines 6 6 of Fig. l, and Fig. 3 is a detail perspective view of a guide used iii connection with the spools.

The prime object ol' the inventionis to pron vide a convenient spooldiolder intended lo take the place of the ordinary spindle or piii now usually employed on sewing-machine arms to support the spool carrying` the needle-thread. rlhe spool-holder supports a series of spools, each of which can be brought in such a position as to conveniently feed the thread to the eyes, take-ups, or other devices employed for leading the thread to the sewing-needle.

A further object of the invention is to econoinize in the use of spcolcotton and spool-sill: by providing a device in which the filled 5 5 spools may be placed,veach being capable of independent rotation and locked in the device until all of the threads have been removed fiom the spools, thus avoiding the loss of spool thread or silk by the misplacement ot' 6o the spool or by entanglement of the threads, which loss is experienced to a serieus extent by large manufacturers of garments.

An upright rod, post, or standard lO is provided atits lower-end with a thread 30, screwing in the arm B of a sewing-machine. The upper end of the standard is provided with a cap l2. Near the threaded lower end of the standard l0 -is secured a cup-like socket 31, provided with a locking-,pin 32, preferably 7o spi'ingac-tuated and adapted to engage one of a series of apertures 34, formed in the rim of a collar 33, mounted 4to turn loosely on the said standard and in the said socket, to be I locked therein at any desired point by the said locking-pin 32. The collar is secured to the under side of a table i6 of any desired contour and turning with its collar on the standard 10. A series ot' upright pins or spindles 29 is secured to the table,- which pins 8o constitute the axes of the spools A and correspond in number to the apertures 34 in the collar 33.

A cover or locking-plate `1S, ordinarily of like contour as the table, is located above the 8 5 latter and is adapted to revolve around the standard and to be supported-on a fixed collar 35 of the standard lO. The under side of the plate 18 when in alowerinost position extends within a short distance of the upper 9o ends ot' the spindles 20 and spools A, as plainly shown in Fig. l.

rIlle cover or plate 1 8 may be locked iii place when in a lowermost or uppermost position by a suitable locking device, preferably a lock 22, secured'to the Linder side of the plate 18 and provided with a sliding bolt 2l., adapted to engage apertures or annular 1e cesses formed in the collar 35 and the upper `end of the standard l0, respectively. '.llieii-ov bolt 2l is preferably actuated b v a suitable key 23.

In connection with each spindle '29 a threadguide 36 is employed, which consists in a metal strip bent to form a horizontal base member d, having an eye il produced therein for the reception of the spindle and an upright, member (Z2, which is carried inward at its junction with the base member at an angle essentially corresponding to the angle ot' the spool-head, as shown at dg, the remainder of the memberbeingperpelidicular. The perpendicular section of the member (lf3 is provided with a longitudinal slot 57, extending from thc top downward, through which slot the thread from the spool is adapted to pass. rlhe guide not only serves as a check upon the rotation of the spool but also prevents the outer layer of thread from falling down upon or over the spool-head and becoming tangled around the spindle. A guide, il*` desired, may be attached to each of the spindies.

In operation7 when the threads have been drawn from the spools in order to replace the empty spools with filled ones,the bolt 21 is shot backward from engagement with the collar 35, and the cover-plate is slid upward upon the standard and the bolt is shot into the upper channel l5 of thc standard 10 to hold the cover-plate in an uppermost position. The empty spools may now be readily removed from their spindles and filled spools may be substituted. \Vhen the table has been refilled with full spools, the cover-plate is unlocked from upper end of standard 10 and lowered and secured in its normal position. The space between the table and coverplate is sufficient to permit Vthe spools to rise upward when the thread is drawn therefrom, but is not sufcient to permit the spools to be removed from their spindles. \Vhen the device is applied to the sewing-machine, the table lo' is unlocked by withdrawing the pin 32 from the apertured collar 33, so as to permit turning ot' the table until the desired spools stand to the left toward the front end of the sewing-machine to deliver the thread to the eyes or take-up mechanisms on the head ot the sewinganachine arm. As soon as the desired position is reached, the locking-pin is again engaged with the corresponding apertures 3l to lock the table in place on the standard 10. When the coverplate 18 is locked on its lowermost position on top of the spindles 29, and the table 16 is prevent-ed from turning by the spring-actuated pin 32 engaging the apertu red collar, then the thread from the spool used at the time is not liable to get entangled in the other spools or the parts of the device, and the spool itself is retained in place on its spindle, an upward movement being prevented by the locked cover-plate and a sidewise motion by the locked table.

It frequently happens that when the thread is quickly pulled or pulled with a jerk the spool tends to move up on the spindle; but a displacement from the latter cannot take place, owing to the position ofthe cover-plate, Furthermore, such a pull or jerk would cause the table to turn on the spindle were it not for the looking device which holds the table securely in place. The thread can be readily un wound from its respective spool and passed directly to the head of the sewing-machine, for which the device is principally intended.

Having thus described my invention, I claim as new and desire to secure by Letters Patentln a device of the character described, the Combination, with a fixed standard, of a table mounted to turn on the said standard, spindles secured in the top of the said table,a collar Secured centrally on the under side of the said table and provided with apertures corresponding to the number of spindles on the said table, and a spring-pressed lockingpin supported on the said standard and adapt-ed to engage one of the apertures of the said collar to hold the spool to be used in proper position, substantially as shown and described.

CHARLES Il. LEWY.
