Specification of Letters Patent.

Patented Oct. 11, 1910.

Application filed July 5, 1910. Serial No. 570,347.

To all whom it may concern:

Be it known that I, CHARLES KAISER, a. citizen of the United States, residing at Greenpoint, Brooklyn, New York State, have invented a new and useful Improvement in Lead-Pencils, of which the following is a specification.

My invention relates to that kind of lead pencil in which the lead core is contained in a wooden sheath; and it has to do with the construction of the sheath.

The usual wooden sheath is composed of two longitudinal sections, which when put together form a pencil stick of cylindrical, oval, polygonal or other desired cross section, and which are grooved in their meeting faces to receive and hold the lead.

It is the object of my invention to obtain in a sheath of this kind, in an inexpensive and simple way, the effect of masaic work or inlaying, without detracting from the strength and practical homogeneity of the sheath. To this end the sheath consists of two wooden sections each having its meeting face composed of a veneer glued to, and having a tongue and groove connect-ion with, the body section, thus insuring solid and permanent connection between the two-the groove for the reception of the lead being formed in and lengthwise of the two veneers. The veneers may, either or both, be composed of a single continuous wooden strip of desired color, or they may, either or both, be composed of a plurality of transverse strips of contrasting color, the grain of these strips running lengthwise of the pencil stick just as does the grain of the ordinary wooden sheath. The outer edges of these strips of contrasting color appear upon the exterior of the sheath, and according to the varying sizes and relative arrangement of said strips many different ornamental effects may be obtained simulating mosaic and inlaid work and the like. WVhen the veneers are composed each of a single continuous strip of contrasting color, that color will appear as a continuous solid color line on the completed pencil stick. I

To enable others skilled in the art to understand and use my invention I will now proceed to describe the pencil and the method of producing the same, in connection with the accompanying drawings forming part of this specification, in which Figure 1 is a perspective view of a lead pencil embodying my invention. Fig. 2 is a cross section on line 22 Fig. 1. Fig. 3 is a View of the two sections of which the sheath is composed, the same being separated and laid with their meeting faces exposed. Fig. l represents two boards which, when put together form a blank of the shape and size from which usually six pencils are producedsaid boards being prepared in accordance with my invention, and being represented with their meeting faces exposed. Fig. 5 is a perspective view of the same when put together to form the complete blank, with six lea-d cores inserted and held in place. Fig. 6 is an end elevation of the blank, Fig. 5, with dotted circles indicating the lines on which the blank is divided up into six pencils. Fig. 7 is a view of a portion of the continuous wooden strip which forms the exterior layer of each board. Fig. 8 is a view of one of the comparatively narrow transverse strips which form-the inner or meeting face veneer of each slot, in case said veneer is made up of a plurality of strips. Figs. 9, 10, 11 are views of pencils having differently ornamented sheaths produced in accordance with my invention.

Figs. 1 to 8 inclusive representa pencil in which the veneered faces of the two boards from which the pencil is made, are composed of alternate narrow stri s of light and comparatively dark wood as, for example, cedar and bass wood)the light strips in the one veneer being so located as to be opposite the dark strips in the other veneer. Fig. 4 represents the two completed boards from which six pencils at a time are made.

The outer layer A of each board is a solid thin strip of wood (6. g. red cedar) of length and width required for the making of the six pencils. The inner layer or veneer face B of each board is made up of thin cross strips of wood of contrasting color as above specifiedlight strips a and comparatively dark strips 6.

The inner faces of the outer solid layers A are longitudinally grooved as at 0, and the outer faces of the'veneer strips a Z) are correspondingly tongued as at (if, so that when laid together on the outer strips A, their tongues cl will enter the grooves c in the latter. There are six of these tongues and grooves in each board one for each pencil. This tongue and groove connection between the veneer strips and the outer solid wood backing A, forms, in conjunction with the glue used to join the two, a very strong and permanent union between the two.

In and lengthwise of the veneer faces of the two boards are formed the grooves e for the usual lead cores Z, six in number. These groovese are located in the inner face of each veneer, so as to substantially regis ter with the tongues (Z on the outer face of the veneer, the tongue serving to thicken the veneer at this pointsutficiently to allow a lead groove of proper depth to be formed, without danger of splitting or cutting through the veneer. It is usual to fit and secure together the veneer strips and their outer solid backings A, while the inner faces of the veneer strips are in unfinished condition, as seen for example in Fig. 8 where one of said strips is shown with unfinished face. After the strips are fitted to and secured to their backing A, the veneer face thus produced is smoothed and dressed down, and grooved as at 6. After the two veneer faced boards have been thus grooved, the leads are placed in the grooves, and the two boards are then glued together, forming a blank such as shown in Fig. 5. This blank is then, by the use of well known cutting and planing appliances, divided into six pencils, as indicated by the dotted lines in Fig. 6.

One of the pencils produced from the blank just described is represented in Figs. 2, 3wherein the same letters of reference are used as in the other figures, to indicate corresponding structural features, and wood layers.

The arrangement of the diiferent colored veneer strips illustrated in ig. t, produces, as seen, a pencil having on diametrically opposite sides of the sheath a longitudinal line of checkered pattern, simulating inlaid work.

Figs. 9, 10, 11, represent some of many other patterns which may be produced by varying the dimensions or relative positions, or both, of the veneer strips. In Fig. 11 the veneered faces are composed each of a solid continuous veneer strip of white wood, forming corresponding longitudinal solid-white lines on opposite sides of the pencil sheath.

In all essential respects however the structural characteristics of the pencils, as respect the tongue and groove connection between the veneers and outer layers A, the grooves in the veneers for the leads, etc., are the same in all the pencils.

Having described my invention and the best way now known to me of carrying the same into practical efiect, what I claim and desire to secure by Letters Patent is as follows:

1. A lead pencil the wooden sheath of which consists of two sections each composed of a continuous outer backing and a veneer facing glued to, and having a longitudinal substantially central tongue and groove connection with, the outer backing, the veneer faces of the two sections being glued together and having formed in them the groove which receives and holds the lead.

2. A lead pencil the wooden sheath of which consists of two sections each composed of a continuous outer backing, and a veneer facing composed of a plurality of comparatively narrow cross strips, placed together edge to edge, glued to, and having a longitudinal substantially central tongue and groove connection with, the outer backing, the thus-formed veneer faces of the two sec tions being glued together and having formed in them the groove which receives and holds the lead.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES KAISER.
