JOHN S. BIRCH, OF NEIV YORK, N. Y.

PENCIL OR CRAYON HOLDER.

SPECIFICATION forming part ofLetters Patent No. 276,659, dated May 1, v1883.

' Application filed September 8, 1882. (No model.)

T 0 all whom it may concern:

Be it known that I, JoHN S..BIRCH, acitizen of the United States, and residing at New York city, in the county and State of New York, have invented new and useful Improve- Figure 1 is a longitudinal sectional: elevation of my improved pencil or crayon holder. Fig. 2 is a similar section of the same, with a modified form of the binding-spring that keeps the pencil or crayon in position. Fig. 3 is a transverse section of Fig.1 on the linear :r, and Fig. 4. is a transverse section of Fig. 2 on line y 3 s t I make the case a, of any approved size, larger than the pencil or crayon b, except at the end 0, where the point of the pencil projects, which I make in reduced size to fit the pencil closely, but so as to allow the pencil to slide freely. In the upper part of the case the pencil .is centered in a cap or pusher, (I, having a little socket, e, for the end of the pencil, and fitted to slide freely up and down in the case, with a light coiled spring, f, about it to push the pencil down when required. Near the point end 0 of the case I have a bindingspring, g, through which the pencil or crayon passes, and by which the pencil is pressed laterally to bind it, so that the spring f will be incapable of pushing it out of place. The bindingpressure of the spring may bear the pencil againstthe case in the point 0, or against a supportingbar, h, lodged in the case near the spring, or any equivalent contrivance may bevused. 'lhen the bar h is not used the spring may have a projection, t, on one or both sides to touch the inside of the ease-when suficient pressure is brought to hear on the pencil to prevent it from being overpressed by the spring. These projections also serve to prevent the bindingspring from springing through the case too far when the pencil is not in, and so obstruct the putting of it in. The

spring y will be roughened in the surface where the pencil passes through it to resist the spring fto the bestadvantage. The pencil may also be roughened in its surface for the same purpose. The springg consists of a fiat strip or wire, bent in a kind of-loop, as shown, in the middle portion, with extended end portions hearing along the inside of the case, while the loop at the middle extends across the case and througha notch, in, in the side opposite to where the said end portions bear, and forming a finger bit or stud,j, projecting just enough above or outside of the case to be pressed inward slightly by the finger to relieve the pencil or crayon of pressure whenever it is desired to allow the spring f to push the pencil forward and project the point; also to relieve the pencil of all pressure while the pencil is being put in the case, which is done by sliding it in through the point 0, back.

It is to be noted that the spring 9 is located with respect to the point of the pencil-case just where it is most convenient for the user to apply the forefinger to the push-bit withoutchanging the pencil from the position in which it is held for use, except, perhaps, to slightly revolve it to bring the push stud under the finger, so that at any time, when he may want to change the point by shifting it in or out, he needs only to put his finger on the bit j and pushing the slide (1- press the point on the paper, if it projects too far, to push it back, or lift the point slightly oh" the paper if he wishes it to be projected farther out. s

For the purpose of extending the pencil when the point breaks off, which is of frequent occurrence, the contrivance will be found much simpler, quicker, and more convenient than any other, and owing to the fact that it does not hold the pencil by gripping it with sharp jaws at the point where it projects from the case, as in many other holders, the points of the pencil will not break oft as easily or as frequently as in other holders.

The construction is also simple, for it will It is desirable to have the parts of the spring around the hole for the pencil to incline toward said hole, as indicated at K, so that when the end of the pencil is presented from either way to the hole of the spring it will be guided thereto, and may thus be more readily passed through the spring, especially when the spring is made of a flat strip.

The flat form of spring is preferred because it affords two points of bearing on the pencil, which insures greater friction with less transverse strain to the pencil than a spring with one bearing-point.

The springfmay be fastened to the side of the case at l by solder or other means, and the case may be extended above the spring for a pen-holder or other device, or it may have a cap to close it.

, The binding-spring 9 may be used without the spring for pushing out the pencil, if desired, the gravity of the pencil, or a thrust of the case by the hand, being depended on for that purpose, as in other pencil or crayonholders; but I prefer to employ it because it acts automatically and facilitates the operation.

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

1. The combination, with case a and pencil b, of a binding-spring, g, constructed substan tially as herein specified, and having a bearing on the inside of the case a, a hole for the pencil b, and a bit, j, projecting through a 5 notch in the case, substantially as described.

2. The combination, with the case a and pencil b, of a binding-spring, g, substantially as herein specified, and a bearing support or stop for limiting the pressure of the spring on the I pencil, substantially as described.

3. The combination, with the case a and the pencil b, of a binding-spring for the pencil secured in the case, without being fastened to it, by resting at the ends on the interior of the case, and by a portion of said spring projecting through a slot or notch of the case, and forming a finger-bit for relaxing the pressure of said spring on the pencil, substantially as described.

4. The combination, with the case a and pencil b, of the binding-spring, bent across the case, substantially as specified, perforated for the pencil, and having two separate and distinct points of contact with the pencil, substantially as described.

5. The combination, with the case a and pencil b, of a binding-spring, ,0, having a bit,j, projecting through the case, and also having a stop, 6, arranged with relation to the pencil and the case, substantially as described.

6. The combination ofaspring,f, and pusher d with the case a, pencil b, and a binding spring, g, constructed substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
