c'RnYoN-HoLnER.

To all whom it may concern;

Be it known that I, HENRY T. BAILEY, a citizen of the United States, residing in North Scituat e', in the county of Plymouth and State of Massachusetts, have invented an Improvement in Crayon-Holders, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. I

The present invention relates to a crayon holder for use in schools, &c., the purpose of the invention being to obtainv a holder which will grip a crayon firmly near the point, and, at the same time, afford a smooth finger piece without external fastening devices which not only interfere with the hold of the user. but are also liable to be slipped out of place and to thereby release the crayon while theholder is'in use. i

'lheholdcr embodying the invention con-- sists of a series of clamping members tapered at their ends.rthese members being wholly inclosed in a casing having a corresponding internal taper, and extending for some distance beyond the point .of thecrayon, so as to afford a smooth surface along the part where the holder is gripped when in. use. 'lhis nember is longitlulinally movable with relation to-a suitable support for the internal gripping members, so that the tapered surfaces coiiperate 'in holding the crayon in the holder. in the construction shown. the longitudinal movel'nent is produced through the agency of a projection from the internal member which cooperates withan inclined slot connected with the external member, so that a portion ofa turn of thelatter, will draw the same up and clamp the crayon.

A further feature of theinvention consists in means for adjusting the position of the projection to compensate for Wear &c.-

Figure 1 is a view, partly in elevationand partly in longitudinal section of a crayon holder embodying the invention, the crayon being shown as" clamped; Fig. 2 is a similar I view of the same with the crayon shown as released; Fig. 3 is an enlarged sectional detail illustrating means for adjusting the projection from the innermember; and Fig.

4 is a further detail illustrating the same ('lrvice. s

The crayon holder"embodying the invention consists of a clamping member having longitudinal yielding arms a preferably formed. in one cylindrical piece by cutting Specification ot-Iietters Patent. Application filed August 4, 1906. -,S'erial No. 329,255.

slots longitudinally in the same, the said members. (.z having, at their outer ends, tapered portions If. These members a may be connected with an extension a of any length desired for the complete crayon holder.

*The cylindrical opening between the members a is of such size as readily" to admit the crayon A which is held in place, after being moved to the desired longitudinal position by means of an external engaging device I) which is in the form of a sleeve, and completely incloses the. members a and is of suificient length to afford a smooth handle port-ion.

The member i) is tapered 'at b to correspond to the tapered portion a of the members a, so that a longitudinal movement of one part with relation to the other will clamp or unclamp the crayon, as shown 'in Figs. 1 and 2. In order to produce such longitudinal movement by a simple and convenient expedient, the part which supports the member a is provided with a pin for projection o which extends through a slot b formed in the member I), the said slot being inclined, as shown, preferably terminating in a portion 7) which is substantially transverse to the axis of the holder. By turning the part b with relation to the inner portion, therefore, the pin will pass from the position shown in Fig. 2 to that shown in Fig. 1, thus producing suificient longitudinal movement to clamp the crayon A, and keep the same in position. Since it is desirable that I the projection 11* should be partially locked, that is to say, should rest. on a surfacewhich is not inclined, such a-sbt, it is desirable to provide for the long tudinal ad ustment of the projection a to compensate for wear,

'variation .in the size of crayons, &c. The

pin and slot, which constitute what may be v termed a locking device, are located near that end of the member 7) which farthest threaded in the internal member or' which may, if desired. have merely a frictional fit therein. it is obvious, therefore, that, by

turning the part II. on its axis, the position of the projection 11* may be varied, the part members,

(1 being herein shown as provided with a.

slot 1, so that it can be manipulated by means of a screw driver."

Claims. I

l. A cayon holder..'comprising :1 main portion having longitudinal clamping membersito engage n crayon; a projection from Y SilHl portion longitndlnally ad ustable with relation thereto; and an lncloslng member to inclose and cooperate with said clamping f nded with an inclined slot, snl'istnntially as and for the purpose described.

said inolosing member being proslot and a rotatable support for said pinto which said pin is ecce'ntriczilly related. I
