JOHN '1. LYNCH, 0F TOLEDO, OHIO.

PENCIL.

Application filed August 18, 1919.

To all whom it may concern:

Be it known that I, JOHN T. LYNCH, a

citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Pencil; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates'to pencils, and has for its object the provision of an improved pencil of the type adapted to removably carry a lead point to permit a replacement of the point when worn, and also adapted to carry a plurality of leads or points for subsequent use.

The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,

Figure 1 is a central longitudinal section of a pencil embodying the invention. Fig. 2 is a similar view thereof, with the lead point holding member removed from the barrel, with its parts relatively moved to release a lead, with a lead point separated therefrom, and with the barrel partly broken away, and Fig. 3 is an inner end view of the lead point holding member with the parts thereof transversely separated.

Referring to the drawings, 1 designates the barrel or shaft portion of the pencil, which is bored or otherwise suitably fashioned in one end to form a chamber 2, which may serve as a receptacle or magazine for extra lead points 3.

The outer end of the chamber 2 is closed by a plug member or lead point holder 4, which is formed in two longitudinally separable parts or halves 4 and 49 that are provided on their inner or coacting sides, at their rear portions, with an interengaging longitudinallysliding tongue and groove connection 5. The rear or inner end of the plug member 4 is provided with an axial projection or stud portion 6, which is formed partly by each of the members 4. 4" and is adapted to fit snugly in the outer end of the chamber 2 to close the same and Specification of Letters Patent.

Patented Feb. 3, 1920. Serial No; 318,133.

to frictionally retain the parts of the penoil in assembled relation. The plug member 4 without the stud 6 is adapted to shoulder against the end of the barrel 1, being of a diameter substantially the same as that of the barrel, and the outer end portion of the plug member tapers to a point and is provided in its point with a lead point receiving socket 7. This socket is coaxial with the plug member and is longitudinally split by the division line of the member with its inner end preferably terminating short of the adjacent .end of the tongue and groove connection 5.

It is evident that by longitudinally sliding the parts 4 and 4 of the plug member, one relative to the other, the inner side of the portion of the socket 7 in one of the plug parts will be uncovered, as .sl10Wn in Fig. 2, to facilitate placing a lead point 3 therein, after which the plug parts may be moved back to their proper relation and placed in holding engagement with the barrel 1, as shown in'Fig. 1. The socket 7 is of suitable diameter to cause the lead point to have a close fit therein so that it will not fall out when the pencil is in use.

It is apparent that I have provided a simple and inexpensive pencil adapted to carry a' plurality of sharpened lead 02 and having a lead point holding head or member which is easily and quickly operable to release one lead point and to have other lead point inserted in holding position therein. It is also evident that the barrel serves to hold the parts of the lead point carrying or holder member in proper point holding relation, and that when the holder is so held it serves as a closure for the magazine or chamber 2 to retain the lead points therein.

I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims. V 7

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,

1. A pencil having a shaft with a socket in one end, a plug member for insertion into said socket slidable interengaging transversely separable sections held in assembled closed relation by insertion of the member in said socket two parts of the' point holding and having longitudinally and cooperating to form a lead point holding socket at the outer end of the member.

2. A pencil having zvberiel forming a. lead point holding chamber which is open at one end of the barrel, and a plug member for insertion into the outer end of said chamber to close-the same, said'plug memher having its outer end tapered and'formed with a, lead point holding socket coaxial nally intersecting said socket.

In Witness whereof I have hereunto signed 15 my'name to this specification;

JOHN T. LYNCH.
