RACK FOR BOBBINS.

movers.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed June 23, 1915. Serial No. 35,821.

To all whom it may concern:

Be it known that I, BENJAMIN F. Cun'rrs, a citizen of the United States, and a resident of Dayton, in the county of Campbell and State of Kentucky, have invented cer tain new and useful Improvements in Racks for Bobbins, of which the following is a specification.

My invention relates to supports or racks; and its object is to hold a plurality of sewing-machine bobbins in such a manner that any one of the bobbins may be conveniently removed from the rack without removing the other bobbins therefrom; thereby avoiding the tangling of the threads on the bobbins as occurs in the ordinary methods of storage with the bobbins thrown loosely into a drawer or other receptacle.

Another object of my invention is to cover and protect the bobbins.

My invention consists in the combination of parts and in the details of construction and arrangement of parts as will herein be more fully described and claimed.

In the drawing: Figure 1 is aplan view of a device embodying myinvention; Fig. 2 is a front elevation of the same; Fig. 3 is a vertical cross section on the line w-m of Fig. 1, showing the device attached to a table by a clamp; Fig. 4 is a front elevation of the same with a cover thereon; and Fig. 5 is a vertical cross section on the line g 1 of Fig. 4.

As shown herein, and as I prefer to construct my invention, there is a back 1, on the rear and lower side of which are mounted clamps 2, by means of which it may be clamped to the edge of the sewing-machine table or other table or object where it may be convenient to mount the device for ready access thereto. Fixed on the front of this back 1, near the respective ends thereof, are forwardly projecting brackets 3; and extending horizontally from these brackets inward toward each other, and in alinement with each other, are the studs 4 with their ends separated to leave a space 5 between them. Upon these studs 4, the bobbins 6 are mounted by slipping the central openings of the bobbins over the studs. c

The space 5 is wide enough to admit sidewise the widest bobbin that is to be stored upon the rack to bring the central opening of the bobbin opposite the ends of the studs 4, whereupon the bobbin may be slidto the left or right along either one of the studs 4; and when a number of bobbins 6 are on either stud as shown, any one of the bobbins may be removed by sliding it to the space 5 between the inner ends of the studs 4 and then slipping the bobbin out through this space. If the desired bobbin is between other bobbins, those at the side near the space 5 may be slid on past the space 5 over onto the other stud 4 until the de sired bobbin is brought opposite to the space 5. In order that the bobbins may thus slide from one stud 4 to the other with facility, a guide plate 7 is secured to the back and curves down under the studs 4 at the middle of the device under the space 5, being substantially concentric with the studs 4 and at a radial distance from them about equal to the radius of the largest bobbin that is to be stored upon the rack. The sides 8 of this guide plate 7 are preferably curved downward to facilitate the passage of the bobbins onto the plate. In addition to this provision, each of the studs 4 preferably has its end 9 tapered adjacent to the space 5,

so that if a bobbin does drop down slightly,

owing to its being radially smaller than the space left between the studs and the guide plate 7, the central opening of the bobbin will still pass onto the opposite stud 4, and the bobbin will rise over this end 9 and pass onto the stud as desired.

When the device is secured on the edge of the work table, the bobbins may be exposed to injury by dropping tools or other objects upon them, and to protect them against this, I prefer to provide a cover 10 extending throughout the length of the device and having a hinge 11 connecting it to the upper edge of the back 1, this cover being of arc-shaped cross section and curving down over the top and front of the rack, covering the bobbins thereon, the lower part of the middle of this cover resting against the upper outer edge of the guide plate 7. 100

For access to the bobbins, this cover 10 may be conveniently thrown back on its hinge 11; and after the desired bobbin is taken from the rack the cover 10 may be as conveniently thrown down over the rack again. Nhen the rack is secured to the edge of a table, as shown in Fig. 6, it may project above the upper surface of the table some what, thereby forming a barrier against the sliding of shears or other tools ofi of the table.

The back 1 is preferably made of wood.

Instead of having the clamps 2, the back 1 may simply be screwed to the edge of the table. The brackets 3 may be of sheet metal and screwed to the back 1. The studs 4 may be riveted in the brackets 3. The guide plate 7 is preferably of sheet metal, with its upper part hooked over the upper edge of the back 1 and curving down and forward as hereinbefore described, there being nails or

screws

12 and 13 passing through the sheet metal into the back 1 at the rear near the top and in front lower down as shown. This plate 7 may be bent to guide bobbins of different radial dimensions, and the studs 4 may be spaced to admit bobbins of difi'erent widths.

I l/hen the plate 7 is made of sheet metal, as shown, and adapted to be easily bent, the cover 10 will have the additional function of guarding this guide plate against being bent out of shape by dropping any object thereon. It will be understood that where it is not desired to use the complete cover for covering the bobbins, a guard may be provided for this guide plate limited to the region of the guide plate and adapted to be thrown back in the same manner that the cover is thrown back.

It will be understood that the construction of my improved device is susceptible to considerable modifications as to the 'details thereof, and therefore I do not wish to be understood as being limited to the precise construction herein specifically shown and described, but

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

1. In a rack for bobbins, two studs in alinement, each adapted to enter central openings in bobbins, and fixed with their adjacent ends spaced apart a sumcient dis tance to allow a bobbin to be slid off and away from either one of the studs, and means to guide such a bobbin from one of said studs to the other across said space.

2. In a rack for bobbins, two studs in alinement, each adapted to enter central openings in bobbins, and having their adjacent ends spaced apart a sufiicient distance to allow a bobbin to be slid off and away from either one of the studs, and a guide opposite said space, in such proximity thereto as to guide such a bobbin from one of said studs to the other across said space while said ends are spaced apart as aforesaid.

3. In a rack for bobbins, two studs in alinement, each adapted to enter central openings in bobbins, and having their adjacent ends spaced apart a sufiicient distance to allow a bobbin to be slid off and away from either one of the studs, and a guide curving under said studs opposite to said space, substantially concentric with the studs and at a radial distance therefrom substantially equal to the radius of the largest bobbin to be held on said rack.

41:. In a rack for bobbins, two studs in alinement, each adapted to enter central openings in bobbins, and having their adjacent ends spaced apart a sufficient distance to allow a bobbin to be slid off and away from either one of the studs, and a guide curving under said studs opposite to said space, substantially concentric with the studs and at a radial distance therefrom substantially equal to the radius of the largest bobbin to be held on said rack, the sides of said guide being curved downward, whereby a bobbin may slide up on said guide when approaching said space between the studs.

5. In a rack for bobbins, an elongated flat back, forwardly projecting lugs on said back near its ends, studs fixed in said lugs and projecting toward each other and in alinement with each other with their ends spaced apart, each of said studs being adapted to project into the central opening of a bobbin, and the bobbin being adapted to be slid along said studs to said space, and said space being wide enough to allow the bobbin to be slid off and away from said studs through said space, a guiding means fixed on the front of said back and curving upwardly under said studs substantially concentric therewith and under said space between the studs, at a radial distance from said studs substantially equal to the radius of the largest bobbin to be held on said rack, to guide a bobbin in passing from one stud to the other across said space.

6. In a rack for bobbins, an elongated flat back, forwardly projecting lugs on said back near its ends, studs fixed in said lugs and projecting toward each other and in alinement with each other with their ends spaced apart, each of said studs being adapted to project into the central opening of a bobbin, and the bobbin being adapted to be slid along said studs to said space, and said space being wide enough to allow the bobbin to be slid off and away from'said studs through said space, a guiding means fixed on the front of said back and curving upwardly under said studs substantially concentric therewith and under said space between the studs, at a radial distance from said studs substantially equal to the radius of the largest bobbin to be held on said rack, to guide a bobbin in passing from onestud to the other across said space, the sides of said guiding means being inclined downwardly to facilitate the passage of a bobbin up onto said guiding means' as it slides along either one of said studs.

7. In a rack for bobbins, two studs in alinement, each adapted to enter central openings in bobbins and having their adjacent ends spaced apart a sufiieient distance to allow a bobbin to be slid off and away from either one of the studs, and a sheet metal guide plate opposite said space, adapted to be bent into greater or less proximity to said space to guide such bobbins of different radial dimensions from one of said studs to the other across said space while said ends are spaced apart as aforesaid.

8. In a rack for bobbins two studs in alinement, each adapted to enter central openings in bobbins and having their adjacent ends spaced apart a suflicient distance to allow a bobbin to be slid off and away from either one of the studs, a sheet metal guide plate opposite said space, adapted to be bent into greater or less proximity to said space to guide such bobbins of different radial dimensions from one of said studs to the other across said space while said ends are spaced apart as aforesaid, and means for guarding said guide plate against being bent out of such proximity as it is bent into as aforesaid.
