:1 slave- Specification. of Letters Patent.

Patented Sept. 9, 1919.

To all 7.0/1.0! it may concern:

Be it known that I, Janus T. DOWDALL, a. citizen of the United States of America, residing at WVoodhaven, Queens county, New York State, have invented certain new and useful Improvements in Spool-Supports, of which the fOllOWlllg is a full, clear, and exact description.

This invention relates to spool-holders forsewing machines. My invention is directed toward the provision of an efficient support for spools of thread, such are-used for inamlfacturing garments or the like in large (1I'l2t1ll3llJlGS. Sewing thread for the above named purpose is supplied in the form of large spools or cops in the form of a coni-- cal spool. It is quite essential that thread for machines which are operated at high speed should be reeled off the spools or cops easily and without danger of catching. My

improved holder is designed to stand upon 7 or be supported over the table of a sewing machine and may be placed in a position best sulted to obtaln good results. 3

A further object of the invention is to provide a holder that can be adjusted to spools or cops of various sizes, and also one that can be cheaply manufactured.

Other features of improvement will be pointed out in the following specification and illustrated in the accompanying draw ing. wherein:-

Figure 1 is a side elevation of my improved spool holder;

Fig. 2 is an enlarged cross-sectional view taken on a line 22 in Fig. 1;

Fig. 3 is a diagrammatic detail view illustrating the manner of supporting a spool of thread;

Fig. 4 is a similar view illustrating the manner of supporting a 001) or conical spool of thread; and

Fig. 5 is a fragmentary side elevation of a modified 'lorl'n of holder.

As herein embodied my invention comprises a block or body member 6 to which the spool or cop engaging arms or members are connected. The spool. or cop engaging arms are indicated by 7 and 8 and are se cured at one end thereof, to angle members or frames 9 and 10, respectively, the frame members 9 and 10 being engaged by a rotatable operating spindle 11 provided with righthand threads 12, and left-hand threads 7 1,3 engaging threaded openings 141 and 15,

respectively, in the frames 10 and 9, respectively. The spindle 11 is rotated by means i of a handle 16, and will, when rotated, cause the arms 7 and 8 to approach or recede one from the other, a pin 17 being utilized to Fig. 3, or a conical cop indicated by 19,65

Fig. 4.

To rotatably support the spindle 11 and also to prevent longitudinal movement thereof, I provide the same, intermediate its ends, with an annular recess 20 (Fig. 2)

which is engaged by a tap-bolt 21. The tapbolt prevents the spindle from premature removal from the block 6 and at the same time permits the spindle to be rotated.

To grip the core of the spool or cop, I provide the outer end of each arm 7 and 8 with a tooth 22 sharpenough to engage or slightly enter the core of the spool or cop.

In combination with the spool 01' cop holder, I provide a thread guide 23 having an eve 2 1 alining with the axis of the block 6. The thread guide is adj ustably supported by a post 25 carried by the block 6 of the spool or cop-holdcr, a set screw 26 serving to maintain the guide 23 in adjusted p0- sitions. The holder and thread-guide are supported by a standard (in this instance) indicated by'27, said standard being provided with a base 28 to enable it to be maintained upon a table of a sewing machine in an upright position relative to the machine proper.

The frame members 9 and 10 not only support the arms 7 and 8, but also serve to act as a backing for a spool or cop, particularly a cop as illustrated in Fig. 4:.

As the core of these cops is tapered it would be diflicult to support them in a hori zontal position,-a osition which isdesirable for the unreeling of the thre'ad,un-

less some means is used to maintain them in said position while the arms or clamping members are being adjusted or applied thereto.

To mount a spool or cop it is but necessary to operate the s indle 11 to cause the arms orclamps 7 anc 8 to come together, after which the spool or cop is placed over the maintenance of said position.

said arms or clamps and forced against the frames 9 and 10, as illustrated in Fi 4. The frames 9 and 10 form the base of the clamp as a whole, and the axes of the arms 9 and 10 are located at a right angle to that portion of said frames against which the spool or cop is forced; hence after the spindle 11 is operatedv to move the arms 7 and 8 apart to gripthe core of the spool or cop, the said spool or cop will be maintained in a horizontal position, the backing provided by the frames 9 and 10 serving to aid in the By means of the above arrangement, the axis of the spool or cop will be maintained in line with the axis of the block' 6.

1 The above described arrangement of parts is particularly well adapted for cops or conical spools of thread. Instead of providing two movable arms I may provide thebloek 6 with a fixed arm 29 Fig. 5 and an arm 30 of angular frame members, a support therefor, a threaded spindle rotatably mounted on said support and engaging said frames,

dle in threaded engagement with the said frames and arranged to cause the arms thereon to approach or recedeonefrom the other, and a guide-pinin slidable engagement with the angular-frames.

3. A spool-holder comprising a support, a

block, angular frames movably associated therewith, spool-engaging arms projecting from the frames, a rotatable operatingspindle in threaded engagement with the said frames and arranged to cause the arms thereon to approach or recede one from the other,- a guide-pin in slidable engagement with the angular-frames, and means tollock the spindle against longitudinal movement. Signed at New York city, N. Y., this 11th day of September, 1918.
