Claims. .1

This invention relates to :a combination bobbin retainer and thread dispenser.

In machine and hand sewing processes it is always required to have two types of thread holders, a bobbin for the sewing machine and a spool for hand sewing. The bobbin must be necessar ly much smaller than the spool since the former must adapt itself to the construction and space limitations in a machine, Whereas the latter :must besuificientlyiarge to be conveniently handled manually. It is an important object of y present invention to obviate the need for such two diflerently sized and constructed thread holders by providing a unitary retainer which will be adapted to rotatably support therein a bobbin arranged for ready removal for use in a sewing machine, .and which can never h l ss conveniently serve the function .of the conventional spool for hand sewing. And in this aspect of my invention it is within my contemplation to provide a retainer member adapted to operatively hold tive of my invention, it a further important object to provide a cover member for the retainer which not only serves as a closure therefor, but which is so constructed as to provide a braking effect upon the bobbins within the retainer, by

a simple manual manipulation. It is my further object, in this connection, to enable the braking device to be operatively released with am-inimum of manual effort, wherebythe threads on the bobbins will immediately be ready for withdrawal,

therein .;a plurality of bobbins of different colored utmost convenience and with least effort. And

in this aspect of my invention it is a further object to provide the device of my invention with a supporting base on which are peripherally disposed a plurality of cutting devices coactively arranged with respect to thread-terminal holding means, so that upon each severing operation of a thread that had been drawn out, the terminal thereof will be maintained in slight frictional engagement with the said base. And it is my further objective, in this connection, to so space the various thread-terminal retaining means with respect to the bobbin holding means as to provide adequate exposed thread lengths for convenient manual grasping.

In conventional devices for manually drawing out thread on a spool, binding means are employed to hold the thread against movement W l the severin operation takes place. Most of these devices employ clamping elements which are in direct en agement with the thre d. t .irict l hold it in place, such engagement ;generally :prosiucing pinching. picking, barring :0 fraying of Still another object of my invention is to enable the cover member operatively to accommodate a pin cushion or other sewing accessory thereon without interfering with the operative manipulation of the braking mechanism through the cover.

It is also an object of my in-ventionto provide the said retainer with means to rotatably support a plurality of bobbins in the manner aforesaid, and yet which will also enable the employment of the retainer for housing other accessories such as pins, scissors and sewingaccessories.-

.And it is within my contemplation to provide a relatively inexpensive, compact andattractive device capable of performing the functions and objectives hereinabove mentioned.

VOther objects, features and advantages will appear from the drawings and the description hereinafter given.

In the form of my invention illustrated in Figures 1 to 6, the casing member I has hingedly attached thereto, at It, the cover member I7, the latter having a catch element i8 engageable with a coacting portion of the casing member if: in conventional manner. The casing member comprises a. flanged base l9 and a retainer member 20, the latter being formed by the annular wall 2| proportioned for coactive interlocking engagement with the lateral wall 22 of the cover Extending upwardly from the floor 23 of the retainer portion 20 are a plurality of spindles 24 disposed circumferentially within said retainer portion. In the preferred form of my invention, the central portion of the casing I5 is slightly raised in the form of boss 25. The said spindles 24 are adapted to rotatably receive thereover the bobbins 26, and are each proportioned to extend below the uppermost flange 21 of the bobbin mounted thereover. And the boss 25 is proportioned to clear the bottom flanges 28 of the bobbins, to enable them freely to rotate. The peripheral wall 22 of cover member ll has a stepped bottom edge 29 which is proportioned to interfit the correspondingly stepped upper edge 30 of wall 2| of the casing. The upper wall 3| of the cover is of flexible material, preferably stiff and resilient, so that it could be manually depressed to the position shown in Figures 4 and 5, and adapted to return to its original position shown in Figure 3 upon a release of the manual pressure. The said wall is so shaped and proportioned that in its normal raised position shown in Figure 3, the under-surface thereof will be out of contact with the bobbins 23 or the flanges thereof. Upon a manual pressure applied to the upper surface of said wall 3|, whereby it will be brought into the position shown in Figures 4 and 5, the wall 3| will be in engagement with the flanges 21 of all the bobbins for frictionally holding them against rotation, in a manner which will more clearly hereinafter appear.

The peripheral flanged portion 32 of base l3 contains, at spaced intervals along the peripheral edge thereof, the open ended slots 33, proportioned to receive therein threads from the bobbins 26. Disposed within the body of flange 32 and extending into the slots 33 are the blades or severing elements 34, the cutting edges thereof extending outwardly for operative engagement with threads disposed within said slots. In adjacent relation to each of said slots 33 are the notches 35 in the upper edge of wall 2|, so that for each slot 33 there is a corresponding notch 35 thereabove. The said notches 35 are preferably placed adjacent each of the bobbins 26, so that for each bobbin there is a corresponding notch.

In operatively employing this device, the threads of the bobbins are drawn through the notches 35 and placed within slots 33, whereby exposed thread extensions 33 are disposed peripherally about the device. If there are different colored threads, there will be an exposed and readily visible array of colored threads adapted to be manually grasped for withdrawal from the retainer and severing. The flange portion 32 extends sufliciently far outwardly beyond the wall 2| to provide a length of each extension 36 adapted for convenient grasping.

It will be observed that (see Figures 3, 5 and 6) when the threads have been drawn through the notches 35, there is no contact of the thread with the bottom edge 23 of the cover I], thereby enabling the thread to be pulled out to any desired length without restriction, the pulling out action causing the bobbins to rotate on spindles 24. When it is desired to pull out a thread, the terminal portion thereof is raised above the holding slot 33, as indicated by terminal portion 36a of Figure 3, and n outward pull applied. When the desired length has been withdrawn, the terminal portion of the thread is again inserted within slot 33, ready for the severing operation. At this point a downward pressure is applied to the upper wall 3|, whereupon it will serve as a flexible diaphragm to engage all the flanges 21 of the bobbins 26. This action causes a braking eiiect upon the bobbins, whereby they will be prevented from rotation. The terminal portion of the extended thread within slot 33 is then brought into cutting engagement with the cutter 34, whereupon the thread will be readily severed.

It is important to note that the braking action of the bobbin has made it unnecessary to apply any pinching action upon the thread during the cutting step, the bottom edge 29 of the cover being at all times out of'engagement with the thread in notch 35, the thread being held against movement only by the action of cover wall-3| upon the flanges. In this way no nickin burring or fraying of the thread occurs, as would be the case where the holding force wouldbe applied directly in contact with the thread. And upon a release of the pressure on cover 3|, it will return to its normal non-braking position shown in Figure 3, the extended portions 36 of the threads being in position to be grasped for a repeated similar operation.

In the form of my invention illustrated in Figures 7 to 9, the casing 31 is provided with a base portion 38 and a retainer portion 39 formed by the annular wall 40, the flanged portion of the base containing a plurality of spaced slots 4| and blades 42 substantially as in the form first above described. This device has no spindles like 24, but in its place contains a plurality of recessed portions 43 within which the lower flange 44 of each of the bobbins 45 rests. Said recessed portions are formed by the central boss 43 and the peripheral bosses 41 extending upwardly from the floor and inwardly from wall 40 as clearly shown in the drawing. The cover member has a lateral wall 49 in interlocking engagement with the lateral wall '43, substantially in the manner described with respect to the first form of my invention, the said wall 43 containing a plurality of spaced notches 50 through which the threads accuser 5.. li l extend, in the manner aforesaid. Upon an outward pull upon a thread, the bobbin will rotate within the casing, the severing action being effected in'the'manner above described.

In-th-is form of my invention, there is a separate diaphragm 52 which is disposed within the inner annular recess .53 of cover 148, the diaphragmhaving the flexible and resilient properties of the wall}! above described. The said diaphragm 52- may be attached to the cover in any known manner, the particular form illustrated showing a plurality of peripheral extensions 54 which are "first inserted into spaced portions 55 of the cover (see Figure'l) andsthen".

rotatably moved to a locking position in the form of a bayonet lock.

The upper wall 56 of cover member 48 has on the innencentral portion thereof the actuating boss :51 which is engageable with the diaphragm 52. Upon applying a pressure to the said upper wall 56 (see Figure 9) the diaphragm will come into engagement with the upper flanges 58 of the bobbins, thereby exerting 'thereupon a braking efi ect; in the manner aforesaid. This arrangement will eliminate the need of resiliency in the wall 56., flexibility being suificient for said wall because of the resilient property of diaphragm 52. other respects the operation of this form of my invention is like that of the first form described. It has still a further feature in that the said boss 36 has a hollow central compartment 46a to receive pins and other sewing accessories.

In the form of my invention illustrated in Figure 10. a diaphragm 59 is employed substantially in the manner shown in the form of Figures '7 to 9. However, the wall 60 of the cover member 6| may be rigid, and adapted to support thereupon a pincushion 62. Attached to the diaphragm 59 is the post 63 of the button member 64, the finger-engaging portion 85 of which being preferably above the uppermost level of pincushion 62, where it is maintained due to the resiliency of diaphragm 59. When it is desired to operatively brake the bobbins, a downwardly pressure is applied to member 64, and the diaphragm will engage the upper flanges of the bobbins to hold them against rotation. Thus this form of my invention has the main features of the forms above described, with the additional feature of a necessary sewing accessory applied to the cover member.

In all the forms above described, it is preferred that the upper flange of the bobbins extend above the lateral edge of the wall forming the casing, such as the walls 2| and 40, thereby enabling the diaphragm portion of the cover freely to contact the upwardly extending bobbins.

The structure of my invention, in its various forms, thus enables a conventional bobbin adapted for use in a sewing machine to be employed for hand sewing also, merely by operatively disposing such bobbins within the casing of my device. The thread is readily withdrawn and cut because of the combination of elements in a self-contained and attractive unit. And should it be desired to use the bobbin for a sewing machine, all that need be done is to open the cover and readily remove any selected one.

In the above description, the invention has been disclosed merely by way of example and in preferred manner; but obviously many variations and modifications may be made therein. It is to be understood, therefore, that the invention is not limited to any specific roan; or man-i ner of practicing same, except insofar .as such limitations are specified in the appended claims.v
