Oct. 18, 1932. L. A. BEARDSLEY PIN BOARD Filed May 29, 1931 lnvsu'ron Patented Oct. 18, 1932 UNITED STATES FPATENT OFFICE LESTER A. BEARDSLEY, OF NORWICH, NEW YORK, A SSIGNOR 'I'O NORWICH WIRE WORKS, INC., F NORWICH, NEW YORx A CORPORATION OF NEW YORK rmiaolmn Application filed May 29,

This invention relates to certain new and useful improvements in pin boards and more The main object of the invention is to pro- Vide a pin board or frame which can be economically produced and is of strong, rigid and lasting construction adapted to effectively support bobbins for steaming or other processing.

A further object resides in the construction of frame which permits, when desired, of forming the parts thereof from aluminum to eliminate any chance of the yarn or thread being contaminated by rust.

Other objects and advantages relate to the details of the structure and the form. and

the relation of the parts thereof, all as will i str psii at each intersection are formed with more fully appear from the following description, taken in connection with the accompanying drawing, in which Figure 1 is a perspectiveview of a pm board of this invention.

Figure 2 is a cross section on line 2-2,

Figure 1.

Figure 3 is a cross section on line 33, Figure 1.

Figure 4 is an enlarged'section through the lower portion of one of the pins and the overlying cross strips illustrating the manner of rigidly securing these parts together.

The pin board, as here illustrated, comprises a frame 1 which may be formed of frame. A secondary set of cross strips 5 are provided extending between the opposite ends 6 and 7 of the frame beneath the primary wire bent into the desired form as, forin- 1931. Serial No. 540,920.

strips 2 butin contact therewith at their inthese strips are secured to each other and t0 a pin 8 in a new and novel manner to produce an improved construction.

For this purpose, the upper strips 2 at each intersection are formed with an opening 9 which may as shown, be of cylindrical form and of uniform diameter throughout. As'distinguished from this, the underlying openlngs 10 registering with the respective openings 9,, but these openings or holes 10 are reamed with a taper so as to provide a substantially frusto-conical surface.

Each pin 8 is formed near its lower end with a. radial enlargement or shoulder 11 havinga fiat bottom surface adapted to rest snugly upon the strip 2, and the portion of the pin below the shoulder 11 may, if desired, be slightly reduced in diameter as compared 7 with the diameter of the body of the pin and is of a size adapted to fit tightly in the opening 9 and extend into the t pered opening 10 in the strip 5. I

With this construction of parts, a rigid and permanent securement of the pin to the strips 38 2 and 5 is effected by riveting the lower end of thepin 8 and enlarging it in this manner so as to fit tightly in the tapered opening 10, drawing the shoulder 11 tightly against the strip 2 and rigidly securing the strips together at each intersection. This construction of connection or mounting of the pins rigidly secures the pins to both of the cross strips 2 and 5, and at the same time, secures the two strips together at each intersection thereby n reinforcing and strengthening the entire frame construction.

'The lower ends of the pins 8 after riveting, as perhaps best shown in Figure 4, may if necessary, be smoothed off in any suitable manner so that their enlarged lower ends constitute an unbroken smooth continuation of the lower surface of the strips 5 so that the strips 5 may constitute effective supports for the frame upon which it slides readily and easily.

I claim:

1. A pin board comprising a frame, primary and secondary sets of cross strips secured to the frame and intersecting each other, said strips havingregistering openings at their intersections, and the openings in the. secondary strips having a tapered wall, and pins having shoulders resting upon: the primary strips and their lower portions extending through said registering openings and their lower ends enlarged to fit tightly within said I tapered wall to firmly unite the pin and the sets of cross strips together.

2; A pin board comprising a frame, a primary set of cross strips having their ends bent upwardly around the frame, a set of secondary strips underneath the primary strips extending at substantially right angles to the, primary strips and having their ends bent upwardly around the frame, said sets of strips having registering openings at their intersections, the openings in the secondary strips having a downwardly and outwardly inclined Wall, and pins having shoulders resting upon theprimary strips, and portions beneath the shoulders extending through said registering openings and the lower ends of said pins being riveted to the secondary strip and fitting tightly within said tapered walls. In witness whereof I have hereunto set my hand this 14th day of May, 1931.
