1 Claim.
This invention relates to certain new and useful improvements in bobbins or the like, the object being to provide a bobbin which is specially light in construction yet very strong and durable.
Another object of my invention is to provide a bobbin composed of parts which are so 'constructed that they can be quickly assembled and When assembled means is provided for preventing the collets from turning in respect to the heads and barrel.
A further object of the invention is to form an interlocking connection between the barrel and heads to prevent the heads from turning in respect to the barrel thereby removing the strain from the connecting rivets.
Other and further objects and advantages of the invention will hereinafter be set forth and the novel features thereof dened by the appended claim.
In the drawing:
Figure 1 is a longitudinal section through a bobbin constructed in accordance with my invention.
Figure 2 is an end view.
Figure 3 is a transverse section; and
Figure 4 is a perspective View of one of the collets.
Figure 5 is a detail section.
Figure 6 is a side elevation of a modified construction of collet.
My improved construction of bobbin or the like is composed of a circular wooden barrel A, stamped sheet metal heads B, collets C and connecting rivets D.
The Wooden barrel A is provided with a central bore A enlarged at its ends to form circular recesses A2 and provided with rivet receiving bores A3 enlarged atrtheir ends to form conical recesses A4. Each head B is formed of a thin stamped sheet metal disc having its marginal portions bent laterally, axially and inwardly to form a reinforced peripheral edge B to prevent the same from being distorted in use and handling. The disc is provided with a central opening B2 to receive the collet C. Stamped on the v.
outer face of the disc around the opening are a plurality of conical sockets B3 to receive the heads D of the rivets D. The conical sockets form conical projections B4 on the inner face of the disc which extend into the conical recesses A4 of the bores A3 to form an interlocking connection between the barrel and heads to prevent the heads from turning in respect to the barrel thereby relieving the strain on the rivets, enabling the use of smaller and lighter rivets for connecting the heads to the barrel.
Each collet C is formed of any suitable light material and is tubular in shape having an annular flange C at its inner end adapted to fit `,snugly in the circular recesses A2 formed in the barrel at the end of the central bore A. The peripheral edge of the fiange C' is distorted by knurling to form projections as shown at C2 which embed themselves in the wall of the recess A2 to prevent the collets from turning in the barrel and head. The tubular collet passes through the central opening of the head beyond the reinforced edge B' of the head to form a bearing for the bobbin.
By constructing the bobbin with heads having means for forming an interlocking connection between the heads and barrel and with collets which embed themselves into the barrel I am able to form the heads of much thinner metal than is the general practice, thereby reducing the Weight of the bobbin without sacrificing the durability of the bobbin as the torsional strain of the collets is carried by the barrel instead of the heads and the torsional strain of the heads is also carried by the barrel instead of the connecting rivets, whereby I am able to use lighter and smaller rivets.
In Figure 6 I show a collet E constructed to be used in a bobbin or the like having the standard thickness of head. The collet is knurled above the ange as shown at E' to engage the wall of the central opening of the head to prevent the same from turning axially in respect' to said head.
While I have only illustrated a bobbin or the like having a solid barrel I Wish it to be clearly understood that the construction of collet herein shown can be used in bobbins or the like constructed of a hollow tubular barrel with a central tubular core. I also do not `wish to limit myself to the particular manner of knurling or roughening of the collets.
What I claim is:
As a new article of manufacture, a bobbin or the like comprising a Wooden barrel having a central bore enlarged at its ends to form circular recesses, said barrel being provided with a plurality of rivet receiving bores enlarged at the ends to form conical recesses, stamped metal heads arranged over the ends of said barrel having formed on the outer faces conical sockets providing conical projections on their inner faces extending into the conical recesses of the barrel collets having annular flanges at their inner ends provided with knurled edges seated in said circular recesses vof the barrel and extending through openings in said head of the same diameter as the collets, the inner faces of the heads surrounding said openings and engagingl the anges of said collets, and rivets extending through the bores of said barrel having conical heads formed on their ends seated in the conical recesses of the heads.
