WALTER HUNT OF NEW YORK N. Y. ASSIGNOR TO WM. RICHARDSON AND JNO.
Specification of Letters Patent No. dated April 10 1849.
To all whom it may concern:
Be it known that I WALTER HUNT of. the city county and State of New York have invented a new and useful Improvement in
5 the Make or Form of DressPins of which the following is a faithful and accurate description.
The distinguishing features of this invention consist in the construction of a pin made
10 of one piece of wire or metal combining a spring and clasp or catch in which catch the point of said pin is forced and by its own spring securely retained. They may be made of common pin wire or of the precious
See Figure 1 in the annexed drawings (which are drawn upon a full scale and in which the same letters refer to similar parts) which figure presents a side view of said pin
20 and in which is shown the three distinct mechanical features viz : the pin A the coiled. spring B and the catch D which is made at the extreme end of the wire bar C extended from B. Fig. 2 is a similar view
25 of a pin with an elliptical coiled spring the pin being detached from the catch D and thrown open by the spring B. Fig. 3 gives a top view of the same. Fig. 4 is a top view of the spring made in a flat spiral coil.
30 Fig. 5 is a side viewof the same.
Any ornamental design may be attachedto the bar C (see Figs. 6 7 and 8) which combined with the advantages of the spring and catch renders it equally ornamental and
at the same time more secure and durable 35 than any other plan of a clasp pin heretofore in use there being no joint to break or pivot to wear or get loose as in other plans. Another great advantages unknown in other plans is found in the perfect convenience of 40 inserting these into the dress without danger of bending the pin or wounding the fingers which renders them equally adapted to either ornamental common dress or nursery uses. The same principle is applicable 45 to hairpins.
My claims in the above described invention for which I desire. to secure Letters Patent are confined to the construction of dresspins hairpins &c. made from one 50 entire piece of wire or metal (without a joint or hinge or any additional metal except for ornament) forming said pin and combining with it in one and the same piece of wire a coiled or curved spring and a 55 clasp or catch constructed substantially as above set forth and described.
