MEANS OF ATTACHING CLIPS TO WRITING INSTRUMENTS Filed April 29, 1948 INVENTOR- .Rczrmondfllhmie A Zinrney Patented Nov. 22, 1949 MEANS OF ATTACHING CLIPS TO WRITING INSTRUMENTS Raymond A. Lanoie, Providence, R. I., assignor to Lew Mfg. 00., a corporation of Rhode Island Application April 29, 1948, Serial No. 24,016

3 Claims.

This invention relates to a writing instrument and more particularly to the means of attaching a clip to the writing instrument.

Clips have been variously formed for attaching to writing instruments in various ways. Usually there is provided a much more complicated arrangement for attachment than that which is herein provided. This complication usually results in more work being done either on the clip or on the instrument prior to assembly or in the assembly. Further, when parts are bound together adjacent a tapered part of a tube, a bulging frequently occurs.

One of the objects of this invention is to provide a simpler means of attaching the clip to the writing instrument.

Another object of the invention is to provide a means for attaching the clip to the writing instrumentso that the clip will not rotate with reference to the writing instrument.

Another object of the invention is to provide a rugged attachment so that the clip is firmly and securely attached to the writing instrument without bulging the instrument.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

Figure 1 is a perspective view of a pencil equipped with a clip which is secured in the manner provided for by this invention;

Figure 2 is a perspective view in exploded relation of the various parts which enter into the attachment;

Figure 3 is a perspective view showing the tubular member of the writing instrument with the clip positioned therein preparatory to the securing means being in place;

Figure 4 is a sectional view illustrating the securing means in place;

Figure 5 is a view similar to Figure 4 but taken at right angles thereto; and

Figure 6 is a sectional view of a modified securing means.

In proceeding with this invention I turn inwardly the end of a tubular member upon which the clip is to be mounted and notch the edge thereof. A clip having a head is then fitted beneath this inturned edge with the shank extending outwardly through th? notch which prevents the clip from being rotated axially of the tubular member. The clip is then secured in place by positioning the head against the flange with one part of the securing means engaging the flange and the other part engaging the head to hold the parts in position by binding upon the flange.

With reference to the drawings, l0 designates generally the writing instrument, which in this case is shown as a pencil. This instrument has a tubular member II which is turned inwardly at its upper end, providing a flange l2, there being a notch l3 in the flange at one location thereof. A clip designated generally 14 is provided with a shank portion [5 to extend along the tubular member II and a head IE which is generally circular in formation with an opening l'l' therein. The size of this circular formation is greater than the opening left after the flange I2 is formed, so that the head l6 cannot pass through the flange by axial movement relative to the tubular member. In assembly the head It of the clip may be positioned through the flange [2 by tilting it at an angle to the axis and passing the head through the notch l3. The clip is then positioned as shown in Figure 3 with the shank l5 parallel to the tubular member II which positions the head l6 beneath the flange l2.

A nut l8 having a threaded opening 29 and screw driver slot 20 is positioned in the tube against the head l6 as shown in Figures 4 and 5. A screw 2| having a threaded shank 22 and a large head 23' is then passed through the opening I! in the head l6 and its head 23, which is of a size larger than the opening in the flange I2, is brought against this flange l2 on the outer edge thereof, and by rotation of the nut within the tubular member by means of a screw driver, the nut may be brought up snug to draw the head against the flange and hold it securely in position.

The nut I8 is of a size no greater than the interior diameter of the flange l2 and thus less than the taper of the tube or barrel at its end portion so as not to exert an expanding pressure on the barrel at the taper.

In some cases the inner member Ill is not threaded and the headed shank 22 is riveted over as at 25 to hold the parts assembled.

I claim:

1. In combination a writing instrument having a tubular member with an inwardly extending flange at one end having a notch therein, a retaining clip having a shank in said notch with a head in a plane generally at right angles to the shank and of a size engaging the inside of said flange with the shank extending along said tubular member and means to bind said head to said flange.

2. The combination of claim 1 wherein said binding means comprises a nut and a screw having a head of a suificient size to engage one of said parts to be bound.

3. The combination of claim 1 wherein said binding means comprises a nut within said member and a screw having a head to engage said flange.
