Description
W. HEATH. SNAP-HOOKS.
No. 193,950. Patented Aug. 7,1877;
WILLIAM HEATH, OF BATH, MAINE.
iMPRoveMEnT IN SNAP-HQOKS.\
Specification forming part of Letters Patent No. 193,950, dated August 7, 1877 application filed May 5, 1877.
To all whom it may concern Be it known that 1, WILLIAM HEATH, of Bath, in the county of Sagadaho'c and State of Maine, have invented certain new and useful Improvementsin Snap-Hooks and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
The nature of my invention consists in the construction and arrangement of a snap-hook, as will behereinafter more fully set forth.
In order to enable others skil'ed in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which the figure is a perspective view of my improved snaphook.
A represents the hook with shank B, at the end of which is formed a loop, G. In the front of the shank B, at its junction with the loop 0, is formed a groove, in which are placed two springs, D D, which are firmly riveted to the shank.
The end of the spring D very nearly meets the point of the hook A, just so close that it will go clear and work by the same both in and out.
In the snap-hooks now generally in use the ill spring runs by the point of the hook and underneath, so that it cannot be worked but one way, and then it has to be pressed down with the thumb or finger in order to get it unhooked. By my invention of having theend of the straight flat spring D coming nearly to the end of the hook, this difticulty is obviated and the spring will work both ways.
The outer spring D is shorter, and is simply applied to give additional strength to the mainspring D,
This snap-hook is mainly intended for drivingreins, but may also be used on other parts of the harness. It can be attached and detached very easily, and'is perfectly reliable.
Having thus fully described my invention,
what I, claim as new, and desire to' secure by
