Description

Patented Aug. 29, 1939 s UNITED STATES PATENT OFFCE Freeland Spool and Bobbin Corp., Hazleton,

Pa., a corporation of Pennsylvania Application September 27, 1937, Serial No. 166,030

3 Claims.

This invention relates to certain new and useful improvements in pin boards for holding bobbins and quills, the object being to provide a pin board which is exceedingly simple and cheap in 5 constructionl and one in which the pins are secured in the cross strips of the board in such a manner that the strips are secured together and the pins rigidly secured within the strips.

Another object of my invention is to provide a pin board which can be used for either holding bobbins or quills, means being provided in the form of a spring for engaging the bore of the bobbin or quill so as to firmly secure the same in position on the pin after being placed thereon.

Another object of my invention is to provide a construction of pin board which is especially adapted to be used for holding bobbins but can be readily converted into a quill board by the addition of the spring means carried by the pin,

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof deined by the appended claims.

In the drawing,

Figure 1 is a perspective view of a pin board constructed in accordance with my invention;

Figure 2 is a vertical section through a pair of cross strips showing a pin extended through the registering openings with a collar thereon before the shoulder has been swaged over the collar to secure the parts together;

Figure 3 is a similar view showing the collar swaged over to secure the parts together; and

Figure 4 is a vertical section through a pin and the cross strips showing the frictional means in the form of a spring secured in position.

in carrying out my invention I employ a rectangular frame l formed of a piece of wire bent into the desired shape and having its ends secured together in any desired manner, such as welding or the like. 'Ihe bars of the frame are connected together by intersecting cross strips 2 and 3, the ends of which are secured to the bars of the frame in any desired manner, such as bending the free ends of the cross strips around the bars of the frame.

The cross strips are provided with openings which register with one another through which pass headed pins li provided with reduced upper end portions 5 forming shoulders 6 as clearly shown in the drawing.

Disposed over the pins are collars 'l which engage the upper cross strips and over which the shoulders E are swaged as shown at 8 for securely fastening the cross strips together and the pins in position within the cross strips so as to form an exceedingly simple and cheap method f locking the cross strips together and the pins in position within the cross strips whereby these pins will be held rigidly in position to receive the bobbins.

In Figure 4 I have shown a pin board constructed as described above provided with spring means for engaging the bore of the bobbin or quill.

To convert a pin board for bobbins into a pin board for quills, or to provide frictional means for either holding bobbins or quills on the pin board, it is only necessary to provide the lpins 9 adjacent the upper ends with transverse openings l and insert a substantially inverted V- shaped spring member Il, the free ends of which are extended through openings I2 formed in the upper cross strips. The ends of the inverted V-shaped spring are bent outwardly as shown at I3 for securing the ends in position whereby spring means is provided for holding the bobbins and quills.

The pin is secured in position within the cross strips in the same manner as disclosed in the preferred embodiment of my invention.

In the preferred embodiment of my invention, a pin board is disclosed without frictional means for preventing the bobbin or quill from rotating thereon while in Figure 4 I have shown a pin board constructed with frictional means in the form of a spring so as to prevent the quill or bobbin from revolving on said pin.

In constructing a pin board in accordance with my invention, it is only necessary to swage the shoulder of the pin into engagement with the collar se as to secure the. parts together and the pin in position and when it is desired to form a pin board with frictional means for preventing the bobbin or quill from rotating on the pin, it is only necessary to aperture the free end of the pin and the upper cross strip adjacent the lower end of the pin which allows the substantially inverted V shaped spring member to be inserted through the aperture of the pin and have its free ends pass through the aperture or the cross strip and secure it by bending the ends outwardly.

What I cla-im is:

1. A pin board comprising a frame, intersecting apertured cross strips having their ends secured to said frame with the apertures registering with one another, headed pins extended upwardly through said apertures p-rovided with reduced upper portions` forming shoulders adjacent their lower ends, collars disposed on said pins engaging the upper cross strips below said shoulders, the upper cross strips being provided with an aperture to each side of said lower cross strip, said pins being provided with transversely disposed apertures adjacent the upper ends and substantially inverted V shaped springs disposed in the apertures of said pins having their free ends extended loosely through the apertures of the upper cross strip' and secured therein by bending said ends outwardly.

2. A pin board comprising a frame provided With overlapping intersecting cross strips connected together by pins, said pins being provided With transversely disposed apertures adjacent their upper ends, the upper cross strip: being provided With apertures to each side of the lower cross strip and inverted substantially V shaped springs arranged in the apertures of said pins having their free ends ,extending loosely through the apertures of said cross strips and secured.

3. A pin beard comprising a frame provided with overlapping cross strips connected together by pins, said pins being provided with apertures adjacent their upper ends and inverted substantially V-shaped springs arranged in the apertures of said pins having their free ends loosely mounted in said cross strips.
