Application April 25, 1950, Serial No. 157,856

6 Claims. 1

This invention relates to improvements in pointer for fusible crayons, candles and the like,

The main objects of this invention are;

First, to provide a pointer for fusible crayons such, for example, as those formed of colored wax or pigment bearing wax, in which the crayon is effectively pointed without cutting or shaving away any of the material.

Second, to provide a device for pointing fusible or plasticizable crayons, candles or the like, the use of which results in uniform points or tips.

Third, to provide a device of the above stated character which may be economically produced and is highly efficient for the purpose.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing, in which:

Fig. l is a perspective view of a pointing device embodying our invention.

Fig. 2 is a vertical central section thereof, a crayon being shown in full lines, the wiring bein also indicated in full lines.

Fig. 3 is a vertical section of a modified form or embodiment of my invention adapted for the pointing of candles as well as crayons.

Fig. 4 is a fragmentary view mainly in vertical section of a modified form or embodiment of our invention as embodied in a crayon pointer.

The embodiment of our invention illustrated in Figs. 1 and 2 comprises a body member I provided with an integral base 2 having a trough 3 at one end thereof. This body member is desirably formed of plastic and is shown in one piece but in practice it would be made up of sections 20! and 2112 joined together by a fused joint as indicated at 4. The chamber 5 is of such dimensions as to receive the shaper member 5 desirably formed of insulating material. The opposed walls 1 and 8 of the body member have recesses 9 and H3 therein receiving the ends of the shaper member. The shaper member illustrated is spool-like in shape and has a heating element ll of the resistance type wrapped around the same. The wall 8 of the body member has an opening l2 therein flared outwardly at I 3, this opening being aligned with the recess ID in the wall and receiving the reduced end I 4 oi. the shaper member. The shaper member has a conical recess l5 adapted to receive a crayon IS.

The circuit connections for the heating element H are indicated at H, the body member being provided with a chamber [8 closed by the plate [9. The circuit connections to the heating element are formed before the casing is closed. One of the purposes in thus forming the casing is to prevent children or others contacting or disturbing the heating element. In use the current is turned on to the heating element and the shaper heated to such temperature as will fuse the crayon to be pointed. The crayon is then inserted in the recess l5 and manipulated back and forth with rotative movement which results in the partial fusing or plasticizing of the tip portion of the crayon and in efiect molds it into the desired point. a

The diameter of the shaper cavity I5 at its outer end is desirably approximatel the diameter of the crayon 0r candle or other object to from flowing out of the recess and retains it to properly mold into the point. The trough 3 is provided so that in the event the crayon or other object is unskillfully manipulated and the material allowed to flow out of the recess it will be caught by the trough; however, a little experience soon enables the efiective pointing of crayons or the like without this occurring and without loss of material.

It is contemplated that the economical procedure is to point a number of crayons after the shaper becomes properly heated, for example this work may be done by a janitor or caretaker in schools or the like.

In the modification shown in Fig. 3 the shaper 2!! is provided with one shaping recess 2| adapted to receive work such as a candle 22. The other end of the shaper is provided with a recess 23 adapted to receive a crayon. The recesses 20 and 23 are connected by the opening 24 through which the wick 25 ma extend. In this case the recess 2! is shaped to produce a concaved taper.

In the embodiment shown in Fig. 4. the shaper 26 is provided with a metal core 21 which is secured in the insulating block portion 26i of the shaper by means of the screw 28. The screw 28 is formed integrally on the metal core 2'! and threadingly engages the hole provided therefor in the insulating block 26L The shaping recess 29 is formed in the metal core 21 and is adapted to receive crayons or other work indicated at 30.

The device of our invention not only enables the effective pointing of work formed of fusible or plasticizable material but it results in a very will enable those skilled in the art to embody or adapt our invention as mayybe :olesi-red.v

Having thus described our invention, whattwe claim as new and desire to secure by Letters Patent, is:
