Patented Jan. 6, 1942 IJNITED STATES.- PATENT OFFICE-=1 I I 2,269,005: v HOLDER FOR MARKERS on RAZOR BLADES Isidore A. Chaikin, Great Neck, N. r. Application JuneZ, 1941,"'soria1 No. 396,262

. 14 Claims. 101. 120-13) My invention relates particularly to a holder for marking chalk. used by tailors and: dressmakers or for holding safety razor blades for ripping seams, as well as to provide a device for accomplishingthe following purposes and objects:

' A holderfor a marker of. wax-like material which prevents the marker from being bent and deformed by the heat and pressure of the hand of the user.

A holder which may use a greater partof the marker to reduce waste.

A holder which may also be used to. sharpen the marker to make a better line.

A holder which holds the marker from slipping. 1

A holder which may also hold a safety razor blade in place of the marker.

A holder easily opened and applied to holding chalk or other things.

I accomplish these and other objects by the construction hereinafter described and shown in the accompanying drawing forming a part hereof in which:

Fig. 1 is a perspective view showing the application of my device.

Fig. 2 is a, front elevation, the back being similar.

Fig. 3 is a front elevation of a modification.

' Fig. 4 is a section at 4-4, Fig. 2.

Fig. 5 is a fragmentary detail in which a part of a safety razor blade has been added.

Fig. 6 is a section at B6, Fig. 5 and Fig. 2.

Fig. 7 is a perspective view of a typical marker or tailors chalk and a part of my holder.

Similar reference characters refer to similar parts throughout the drawingand in the specifications to follow.

My holder is particularly adapted to hold the wax-like chalk mostxcommonly used in marking fabrics, and which is ordinarily used by tailors,

dressmakers, and for manufactured articles made of fabric. The chalk, a common term for this marker, is softened by the heat of the hand and soon becomes bent, twisted and otherwise deformed.

The surface of the marker is slippery and difficult to hold and by the use of my holder, the

seams and for other purposes and is instantly removable.

Referring to the drawing, the construction of my holder may be followed. The side members I and 2 are preferably hinged to each other 3 along the edges 4 and 5 which are provided with by holding either firmly in place between the side members I. and 2 which clamp and securev the hinge bosses Ii. which. are rolledover. and

around into cylindrical form to engage the hinge of the side members I and 2 and. projecting be-' yond the edges 4 and 5, I have provided the handle levers III and. IIiwhi'ch, when pressed toward each other open the side members, causing them tojmove. apart or away from each. other against the tension of the torsional spring I2 which is coiled around said hinge pin I and has its ends resting against the inner surfaces of the handle levers I9 and II which are preferably curved transversely, and the side marginal edges I3 are fia'ngedqinwardhy to stiffen said handle levers and also preventthe' ends of the torsional spring.

from becoming disengaged. The torsional spring operates the side members to close them and to hold them closed on. the marker I4 orrazor.

blade I5.

To permit the marker. to be nearly covered by said side members and to provide air spaces I4 between themarker and said members, each.

Between the pads and. the edges-I6 and IT of themembers I and 2, I have provided the inwardly depending toothed. flanges 22 and 23 whichare pressed inwardly from the metal of the side members thereby forming the slots 24..

The end teeth. 25 are spaced longitudinally to engage the ends 26 of the. slot 21 of the safety razor blade I5 and the toothed flanges 22 and:

23 are spaced apart to suit the width of said slot 21, thus holding said. razor. blade in place between. theside members I and2 which clamp the razor blade firmly in place.

The. intermediate teeth 28 are preferably openly spaced to engage and penetrate and grip the marker I4. The teeth" and flanges thus are positioned to either engage the slot of a safety razor blade or the material of the marker, therethem by means of the tension of the spring, I2

1 and further by the pressure of the. thumb and:

fingers on the pads 2| and22.

In Fig. 3, I have shown a modification which is provided with side members a and b hinged c at the end 01. The handle levers fproject beyond the hinge c at the end. The slot'g and.

toothed depending flanges may be positioned at the center of the members and knurled pads h and i may be positioned at both sides of the slot 9.

I have herein disclosed, in detail, a preferred construction embodying the underlying principles of my invention. To those skilled in the art to which this invention pertains, modifications may be apparent, and I do not wish to be limited to the details herein disclosed, which are to illustrate rather than to limit the scope of my invention, which is set forth in the appended claims. I r

I claim:

1. In a holder, a pair of hingeably secured side members having a sharpened edge opposite the hinge and a slot having toothed inwardly depending flanges positioned near to and parallel with said sharpened edges, and a pair of lever handles integral with said side members projecting beyond said hinges.

2. In a holder, a pair of hingeably secured side members having a sharpened edge opposite the hinge and a slot having toothed inwardly depending flanges positioned near to and parallel with said sharpened edges, and a pair of lever handles integral with said side members projecting beyond said hinges to open said side members when pressed.

3. In a holder, a pair of hingeably secured side members having a sharpened edge opposite thehinge and a slot having toothed inwardly depending flanges positioned near to and parallel with said sharpened edges, and a pair of lever handles integral with said side members projecting beyond said hinges, and a torsional spring having its ends bearing against the inner surfaces of said lever handles to close said side members.

4. In a holder, a pair of hingeably secured side members having a sharpened edge opposite the hinge and a slot having toothed inwardly depending flanges positioned near to and parallel with said sharpened edges, and a pair of lever handles integral with said side members projecting beyond said hinges, and knurled pads positioned between said slots and said hinges.

5. In a holder, a pair of hingeably secured side members having a sharpened edge opposite the hinge and a slot having toothed inwardly depending flanges positioned near to and parallel with said sharpened edges, and a pair of lever handles integral with said side members projecting beyond said hinges, and knurled pads positioned between said slots and said hinges facilitating a grip between the thumb and fingers, and spring means cooperating with the thumb and fingers in clamping a marker or razor blade between said side members.

6. In a holder, a pair of hingeably secured side members having a sharpened edge opposite the hinge and a slot having toothed inwardly depending flanges positioned near to and parallel with said sharpened edges, and a pair of lever handles integral with said side members projecting beyond said hinges, and knurled pads positioned be tween said slots and said hinges facilitating a grip between the thumb and fingers, and spring means cooperating with the thumb and fingers in clamping a marker or razor blade between said side members, said marker or razor blade being released and removable by pressing said lever handles.

7 In a holder for a slotted razor blade or waxlike marker, a. pair of hinged spring operated side members, each having a pair of toothed depending flanges to suit the slot in said razor blade or to engage and penetrate said marker.
