` Ewige GEORGE W. WEISS, OF NEW YORK, N. Y.

v SPOOL-HOLDER FOR SEWING-MACHINES.

To all LU/7mm t may concern.'

lic it known that I, Grenen W. I/Vnss, a citizen of the United States,.and resident of New York city, in the county of New York and State of N ew York, have invented certain new and useful Improvements in Spooll-Iolders for Sewing-Machines, of which the following is a full, clear, and exact description.

rlhe invention relates to spool holders for sewing machines in which av plurality of spools of thread or silk of different sizes and colors are supported on the machine to enable the operator to use either one of them at will, and has for its object the construction of an in'iproved spool holder, in which a plurality of spools can beheld with .no danger of falling off, and in which the full and empty spools can be easily and quickly replaced or removed without loosening any screws, catches, or fastening devices of any kind.

.f1 further object of the invention is to provide a pin cushion on the holder in such a way that it will not interfere with the operation either of the spools or the sewing The invention involves various features of the attachment which will be described more fully hereafter and particularly pointed out in the claims. Reference iste be had to the accompanying drawings forming a part of this specificati on, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front view of my invention applied to the sewing machine.

Fig. 2 is a plan view of Fig. 1 on the line QMQ..

Fig. 3 is a sectional view of Fig. 2 on line 3 3.

Fig. 4 is a view of the lower plate of Fig. 1 with tubes l attached.

Figs. 5, 7, 8 are sectional views of modified forms of friction devices.

(l is a view of a spool holder in which the spool pins are fastened to the lower plate.

Fig. 9 is a sectional view of Fig. 8 on the line 9 9.

In the annexed drawings I have shown only a part o-f the sewing machine head as '1, and spool pin as 2, it being understood that this attachment can be applied to any sewing machine.

In the construction of my improved spool holder I provide a plate 3 to which is se- Speecation of Letters Patent.

cured the tube 4, the upper end of which is slotted about half of its length as shown at 5, in Fig. 4L, with `four slots. These slotted ends are pressed toward each other so that the hole in the tube at the ,slotted end'becomes smaller as shown in Fig. t. The slotted ends being pressed in causes a friction pressure on the spool pin. I/V hen the tube t is placed over the spool pin on the sewing machine the slotted, end grips the pin with suliicient force to hold the spool stand on the pin securely without any screws, catches, or other locking devices, so that it cannot turn with the vibration of the machine, or fall ofi: when the machine head is dropped into the table on drop head sewing machines.

I further provide another plate G to which the spool pins 9 are secured. To this plate 6 I also secure a tube 7, the end of which is also slotted and pressed toward each other, to make the hole in tube smaller at the slot ted'end, to cause a friction pressure. rlhe tube in plate 6 is large enough to lit over the tube in plate 3. The spools are placed on pins 9, and the slotted tube 7 is pressed Patented J une 5, 1917., Application mea Api-i1 so, 1915. serial No. 24,934.

over the tube 4t on plate 3., The slotted end of tube 7 also holds with a friction pressure caused by the slotted tube being pressed in. By this construction the plates 3 and 6 are held 'together by pressure without any screws, catches or fastening devices of any kind, with the spools between them, so that they will not change their position unless moved by hand.

'Io the upper part of plate 6 I attach a pin cushion 11, of any well known style. The spool pins 9 that are attached to the plate 6, are made just long enough so that when the plate 6 is put on plate 3, there will be a space between the ends of pins and plate 3. This is for the purpose of allowing the coils of thread that may fall from spool to slip on? under the spool and not catch. In some cases it may be desirable to secure the pins 9 to plate 3, as shown in Fig. 6, instead of plate 6.

In Figs. 5, 7, 8, I have shown modified forms of devices to cause the friction pressure between the spool pin 1 of the sewing machine and plate 3, and also between plates 3 and 6, Fig. 5 being constructed with a friction device attached to .plates 3 and 6, but the tubes 12 of which the friction device is made are both the same size, so that each friction device will grip the spool pin di rectly, as shown, the two friction devices meeting on the spool pin, and not one fitting Fig. 7 is constructed of two tubes, one fitting over the other, as in Figs. 1, 2, 3 and 6, but the tube secured to the lower plate 3 is plain and has no friction device. I obtain the friction on lower plate 3 by putting a spiral springk 14 on top of tube 13 on plate 3.

On top of spring 14 I put a washer 15 to hold spring on. This gives friction pressure on lower tube and plate. This also fixes the lower plate permanently to the machine. Upper plate 6 and tube 7 are made with friction pressure the same as shown in Figs. 1 and 3. In Fig. 8, I provide fiat steel springs 18 and 19 that are secured to the inside of tubes 16 and 17. The tubes 16 and 17 must be made large enough to permit of the insertion of springs 18 and 19 as shown in Fig. 9.

While this device is readily 'attachable and detachable from the sewing machine, I do not wish to limit myself to this feature as it might be rdesirable to permanently affix it to the machine, in which case I would affix it as shown in Fig. 7. The bottom plate `3 should be large enough so that the spools cannot slip off the pins at the bottom, and if the pins are on the plate 6, the plate 6 will have to be large enough to prevent the spools from coming on. The spool holder` constructed in this way makes a simple, compact, efficient device, holding the spools in a secure manner without screws, pins,

locks or catches of any kind.

With this friction device, any spool can instantly be brought into position to be used on the sewing machine.

I am aware that spool holders have been made that were attached to the sewing machine with screws or bolts or nuts. rlhisI do not claim.

yI do not wish to limit myself to the particular construction shown and described as various modifications may be made without departing from the kspirit of the invention.

What I claim as new, and desire to secure by Letters Patent is:

1. The combination in a spool holder of upper and lower plates, frictional devices to secure the two plates to the sewing inachine with a space between, spool pins carried by one of the plates, and a pin cushion attached to one of the plates. f

2. The combination in a spool holder of upper and lower plates, a frictional device on each plate forsecuring it to the sewing machine with a space between the plates to contain the spools, spool pins secured to the upper plate, said pins terminating short of the lower plate for the purpose of allowing the coils of thread toslip off under the spool.
