United States Patent CRAYON HOLDER Thomas C. Estes, Dallas, Tex.

Application February 9, 1954, Serial No. 409,229

2 Claims. (Cl. 120-19) This invention relates to a crayon holder and more specifically provides a device for holding all types of crayon, chalk or other such marking material.

An object of this invention is to provide a crayon holder which is simple in construction, easy to use, well adapted for its purposes and relatively inexpensive to manufacture.

A further object of this invention is to provide a crayon holder which may be easily refilled and used for holding various types of crayons or chalks which are disagreeable because of their soiling qualities and which are brittle and easy to break which causes excess waste of such materials.

Yet another object of this invention is to provide a crayon holder which has a novel means for clamping the crayon in the holder and independent means for providing a longitudinal adjustment of the crayon in the crayo holder.

A still further object of this invention is to provide a crayon holder having an improved clip thereon for positioning the holder in a persons pocket or the like wherein the crayon or chalk will not engage the pocket of the person carrying the chalk.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accom- M Figure 3 is a detail section taken substantially along section line 3--3 of Figure 1 pocket clip construction;

Figure 4 is a side elevational view showing the crayon holder of the present invention; and

Figure 5 is a vertical section taken substantially along section line 5-5 of Figure 2. showing the end construction of the U-shaped clamp and the spacer between the clamp for retaining the legs of the U-shaped clamp in spaced relation.

Referring now specifically to the drawings, it will be seen that the numeral 10 generally designates the crayon holder of the present invention including a tubular sleeve 12 having an open end 14 and a removable cap 16 forming a closure for the other end of the sleeve 12. The open end 14 is generally reduced slightly from the over-all area of the sleeve 12 and includes an outwardly flared portion for guiding movement of a crayon 18 positioned therein. Positioned adjacent the open end of the sleeve 12 is a bar 20 secured thereto by a suitable welding or riveting and being generally parallel to the tubular sleeve showing the details of the ice 12 in spaced relation thereto and terminating in a free end portion. A'gripping member 22 is slidably positioned in an aperture 24 adjacent the free end of the bar 20 and a gripping washer 26 is positioned on the inner end of the gripping member 22 and a knurled head 28 is secured to the outer end thereof. A coil spring 30 is disposed around the gripping member 22 and abuts the upper surface of the washer 26 and the undersurface of a washer 32 thereby urging the gripping washer 26 and the gripping member 22 towards the sleeve 12 for gripping the edge of a persons pocket or other supporting material. It will be understood that the coil spring 30 provides a greater latitude of supporting material than the usual spring clip utilized for supporting a crayon holder.

Positioned in the longitudinal side of the tubular sleeve 12 is a slot 34 having a closed end adjacent the opened end 14 of the sleeve 12 and being open at its other end. The open end of the slot 34 is closed by the removable cap 16 for a purpose described hereinafter. Positioned and slidable in the tubular sleeve 12 is a U-shaped clamp 36 having free legs portions 38 and a bight portion 40 formed into a pair of legs 42 having a curved bight portion 44. The free legs 38 have generally concave facing surfaces for receiving the periphery of the crayon 18. Alined apertures 46 are provided in the legs 42 and a screw-threaded member 48 is freely positioned in the apertures 46 and the screw-threaded member 48 has an enlarged headed portion 50 at its inner end and extends outwardly through the slot 34 and terminates in a knurled head portion 52. A pair of upstanding lugs 54 on the outer surface of one of the legs 42 receives and captures a nut 56 which is threadably engaged with the clamp screw 48 wherein the leg portions 42 and the leg portions 38 are moved inwardly and outwardly in relation to each other by manipulation of the knurled head 52. A spacer 58 is positioned between the legs 42 and surrounds the screw member 48 for limiting the inward movement of the legs 42 and the inward movement of the legs 38 in an obvious manner.

As illustrated in Figure 2, the legs 38 are generally shown in an unbiased condition whereby the inherent resiliency of the clamp 36 permits the clamp screw 48 to tighten and loosen the legs 38 for clampingly engaging crayons 18 of varying sizes. The clamp screw 48 is shown in loosened position for purposes of clarity. The crayon 18 is positioned in the clamp member 36 when the clamp member 36 is at the open end 14 of the sleeve or withdrawn from the open end of the slot when the cap 16 has been removed thereby eliminating breakage of the crayon when positioning in the sleeve. Once the crayon is securely positioned in the clamp member 36, there is usually no necessity for loosening and tightening the clamp member 36 except for renewal of the crayon. By rotating the knurled head 52 of the bolt 48, the headed end 50 and the nut 56 will engage the opposite surface of the leg members 42 of the clamp member 36 thereby urging the leg members 38 together and the inherent resiliency of the device will generally spread the leg members 38 apart when the bolt 48 is loosened. However, if desirable, the clamp member 36 may be loosened within the sleeve with very little canting inasmuch as it will be noted in Figure 5 that the peripheral edges of the legs 38 and the inner surface of the sleeve are substantially concentric and positioned closely adjacent each other.

A plate 60 having an aperture 62 in one end thereof is positioned around the shank of the screw-threaded member 48 and the opposite end of the plate 60 is provided with a returned bent portion 64 having aligned apertures 66 therein for receiving a screw-threaded securing means 68. The screw-threaded member 68" has a headed end portion 70 on the inner end thereof and an enlarged knurled head 72 at its outer end for manipulation thereof. 'The'returned bent portion 64r6rrnpaeea parallel portions for receiving a nut 74 threadably engaging the r a e m e at an a @Pfitilh? flange 76 on the remote end ofthe returned bent portion 64 engages the nut '74 thereby capturing the relation to the plate 6.0. 1 friction washer 78 surrounds screw-threaded member 68 and a coil compression spring 80 is positioned between the knurled head 72 and the washer "Z8 urging the washer "Z8 .a gainst'"the sleeye 12 adjacent the slotfid. It will be seen that the plate 69 surrounds the shank of the screw threaded rriembe and sleeve 12 adjacent the slot It be seen that the plate .60 surrounds the shank of shrew-threaded member 4 and bridges the slot wherei m i p rla tion of the knurled head '72, the plate 6Qrnay be securely to the fileege 12 thereby securing the 'tl-sbaped clamp'36 in longitudinally adjusted relation in the tuhuiar sleeve 12. It will be een that by removal of 3 the entire mechanism mat 319 rem ved the eby t e the Iease'of replacement of the The operation of the device'willlbe readily understood. The removable cap 16 is removed and the .screw thteaded members 68 loosened 'therehy pennitting the tilshaped clamp 36 to be remo ied froni memb ui sleeve 12 By manipulation of the" screw-threaded inernher' the crayon 18 'niayhereplaced'and the Ushaped clamp 36 returned into the sleeve 12 with the of the

It will be seen 'thatthe device or present inyention prevents the usual soiling of a persons clothes thatutilizes such chalk or crayon. The device willfb'eespecially useful in schools, lumber yards or the like wherever this type of crayon or chalk may be utilized, The reduced end portion 1 4 provides a secondary support for the crayon 18 thereby preventing the brittle crayon from Being "brokenas usually happens thereby causing the waste of the crayon or chalk 18.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the enact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
