Specicaton of Letters Patent.
Patented April 20, 1909.
Application led November 30, 1908. Serial No. 465,317.
To all whom 'it may concern:
Be it known that I, HARRY A. EVERY, citizen of the United States, residing at Boston,
chusetts, have invented a certain new and useful Improvement in Insulated Tools for Marking with Metallic Leaf, of which the following is a specification, reference being had therein to the accompanying drawings.
In marking with metallic leaf such for instance as gold leaf, upon various objects, itis common to lay the metallic leaf u von the object to be marked, the metallic eaf having superimposed upon it a suitable backing of paper or other sheet material, and then to im ress u on the backing, either by a heated rol er or by a pointed instrument or other suitable tool which has been heated, the outline of the design that itis intended to transfer in metal to the object to be marked.
In order to cause the gold or other metallic leaf to adhere to the object to be marked along the line traced'by the marking instrument, it is necessary that the marking instrument should be heated, When this marking instrument is a hand tool, such for instance as a metallic pencil or stylus, it is necessary to have an insulated or non-heat conducting hand grip in order to avoid burning the hand, and also to serve to prevent too rapid radiation of the heat from the point of the tool. v
The object of my invention is to provide a marking tool for marking with metallic leaf having an insulated Enger grip for the purposes above set forth.
T from the following description taken in connection with the accompanying drawings, and the novel features are pointed out and clearly defined in the claim at the close of the speciiication.
In the drawings :Figure l is a plan of a tool embodying my invention. Fig, 2 is a longitudinal section. Fig. 3 is a plan of the insulating sleeve detached; Fig. 4 is a plan of the point and Fig. 5is a plan of the handle rod detached. Y
Referring to the drawings,-l represents the point of the toolwhich is made somewhat e invention will now be fully understood conical and is of metal, 1preferably steel, and is formed with a shan 2 extending rearwardly, the said shank being of considerably in the county of Suolkand State of Massaless diameter than the diameter of the rear end of the point l, thus forming a shoulder 3 at the junction of the shank with the rear end of the point. The shank 2 is` tapped out forming a screw-threaded socket 4. A metallic rod 5 ofthe same diameter as the shank 2 is formed with a reduced forward end having a screw-thread 6 which is adapted to screw into the tapped out socket 4. The rear end of the rod 5 is provided with a head 7 which may be either integral therewith as shown, or it may be a nut adapted to screw onto the rear end of the rod.
An insulating sleeve 8 of any suitable nonheat conducting material, but preferably asbestos or asbestos composition, is provided which is adapted to fit over the rod 5, the rear end of the sleeve abutting against the head 7 and the forward end of the sleeve abutting against the shoulder 3 when assembled. In order to assemble the parts, the rod is first inserted into the sleeve until the rear end of the sleeve abuts against the head l7 and then the shank 2 of the point is inserted'into the opposite end of the sleeve from the head 7 andscrewed onto the threaded end of the rod, bringing the shouldered end of the point back up against the forward end of the sleeve, thus clam ing the sleeve between the shouldered end of) the point and the head 7. The insulating'sleeve thus forms the hand and finger grip which entirely protects the hand and fingers from the heat even when the point is highly heated for use and also materially aids in preventing too ra id radiation of the heat from the rod and t ereby retards the cooling of the-point. The parts are easily assembled and detached.
at I claim is:
An insulated tool for marking comprising a metallic point member having a rearwardly l projecting shanliportion of reduced diameter forming a shoul er at its junction with the head, said shank having a ta ped out socket in its rearend, a metallic rodlhaving its main portion of the same diameter as said shank,
one end being reduced end adapted to screw 1 the sleeve between the seid shouldered end into said socket and having its other end proend the head of the rod. l0 vided with a head, and a sleeve of insulating n testimony whereof I affix my signature, materiel which is adapted to iit over said in presence o1 two witnesses.
