JOHN J. REQUA, or NEW YORK, N. Y.

CAUSTlC-PENCIL HOLDER.

To (all whom it nuty concern:

Be it known that I, JOHN J. REQUA, a citizen of the United States, residing at the borough of Brooklyn, city of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Caustic-Pencil Holders, of which the following, taken in connection with the accompanying drawings and the letters of reference marked thereon, is a full, clear, and exact specification.

This invention has relation to holders for caustic-pencils such as are employed by physicians and others for cauterizing and analogous purposes. These caustic-pencils usually consist of rather short points of caustic material, such as nitrate of silver and other substances, which are brittle and liable to be broken and otherwise damaged and thereby rendered inapplicable for proper and efiicient use.

The principal object of my invention is to provide or produce a simple, cheap and efficient form of holder for caustic-pencils Wherein the pencil point will be sustained in ayielding manner so that it will not be liable to be broken on being dropped or by being carelessly handled and so that the pencil may be easily carried about in the pocket or in a case without being subjected to damage in the usual ways.

A subordinate or an additional object is to provide a caustic-pencil with which a Wound or other surface may be touched in a yielding manner, whereby the pencil may be more efficiently used, and this with less shock to the patient and less liability of being itself broken or damaged should the patient jump or start under the application.

To accomplish all of the foregoing objects and to secure other and further advantages in the matters of construction, operation, adaptation and use, my invention involves the mounting of the caustic-pencil point in a flexible or yielding seating which in turn is secured in a suitable handle, and certain novel and useful arrangements or combinations of parts and peculiarities of construction, as will be herein first fully described and then pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a view in elevation showing my improved causticpencil holder with the cap or cover removed and the pencil point exposed as for use. Fig.

Specification of Letters Patent.

Application filed November 16,1905. Serial No. 287,573.

Patented June 11, 1907.

2 is a vertical View, the upper portion being I in section, showing the holder with the cap or cover in place thereon, as when the device is to be carried about upon the person or otherwise, and showing the usual coating of wax or other similar protective substance upon the pencil point to prevent deterioriation until it is necessary to remove it for use of the pencil. Fig. 3 is a horizontal section on a plane through line of Fig. 2.

In all these figures like letters of reference, wherever they occur, indicate corresponding parts. 1

A represents a caustic-pencil point of the ordinary form and size and made of any of the usual materials.

B is a suitable handle which may be of wood or rubber or suitable material.

According to my invention the pencil point, A, is mounted in the end of a tubular section, C, and this is flexible or yielding and preferably made of rubber in which the pencil point is securely mounted by the applica tion of a little glue or other adhesive substance. The receiving end of the handle, B, is most conveniently bored out as indicated to supply a suitable cavity for the reception of the flexible piece C, the same being connected with the handle so as to maintain the pencil point at alittle distance from its extremity to provide for the slight yielding of the pencil point when mounted in place and in ac cordance with my invention. The tubular section C may be conveniently secured within the cavity in the handle by a little glue or other adhesive substance applied at any point. I however prefer to make the flexible section of diameter a little smaller than that of the cavity in the handle and to secure the flexible section in place at its inner extremity, as at a, thus affording a longer length of tubular section which will yield under the effect of vibration or touch of the IIO brought in contact with any object will yield as far and as easily as its flexible mounting will permit, and this flexibility may be varied as may be found necessary or desirable by varying the consistency of the tubular section C.

A removable cap or cover E is to be mounted upon the end of the handle as is usual in other forms of caustic-pencil holders, and within this, it will be observed that the pencil point may vibrate to a considerable extent without danger of being broken by contact with the interior of the cap or cover. This permits the improved pencil holder to be carried about without danger of being damaged when it is not in use.

The flexible section C may obviously be mounted in connection with the handle in other ways than the particular one shown, and instead of being made in the form of a tube it might be of solid elastic or easily flexible material, and other immaterial variations in the particular formation of the parts may be made without departing from the scope of the invention.

Being constructed and arranged substantiallyin accordance with the foregoing explanations, the improved holder for causticpencils will be found to admirably answer all the purposes or objects of the invention hereinbefore alluded to.

Having now fully described my invention, What I claim as new herein and desire to secure by Letters Patent, is

1. In a holder for a caustic-pencil, the combination of a handle, a caustic-pencil point, and a flexible holder for said point, the handle being provided with a cavity in its end, and the flexible holder being secured in place in the lower part of said cavity and capable of vibrating therein, substantially as and for the purposes set forth.

2. The herein described holder for a caustic-pencil, comprising a handle provided with acavity, a yielding holder connected with said handle, a caustic-pencil point mounted in the end of the yielding holder, and the removable cap or cover, all being combined and arranged substantially as and for the purposes set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
