Description

Y @gleiten tittes aten't @frn IMPROVED' SNAP-HOOK.

TO ALL WHOM IT MAY GONCERN;
Be it known that I, ENoCH GOVERT, of Farmer Village, in 'the county of Seneca, and State of New York', have invented e, new and improved Snap-Hook; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and usethe same, reference being had to the accompanying drawings, forming part `of this specification.
This invention 'relates to an improved snap-hook, and consists in having thesprng which operates the closing-har countersunk in the shank of the hook. In the accompanying drawings- A Figure 1 is a front view of my improved hook, and
Figure 2 a section thereof at line :z:
Similar letters of reference indicate like parts.
A is the hook; a its shank; B the closing-bar, operated by the spring C, countersunk-in the' shank a, and secured by the lips closing over, as shown at b, iig. 2. The spring is thus securedfrominjury, cen be readily replaced in case of damage, and the clasp hook on my improved principle can be constructed more cheaply than by any other methods now in use. The spring'C is upon thetep of the closing-bar, whereby the formation ot" a space beneath such barfor the operation efe spring from Athe under side is prevented, suchincreased space having a tendency to weaken the body, and hy`becoming filled with dirt prevent the free operation oi' the closingbar. By my invention the top is entirely closed, and the introduction of dirt eii'cctually prevented at all times. When the spring becomes broken it is not necessary to remove the closing-bar for the application of a new springhas in the case of the snaphoohs of ordinaryrmanufacture, but by slipping it from beneath the lips b, a new spring can be applied with ease and facility.
I claim as new, and desire to secure by Letters Patcntl i The spring C applied te the top of the closing-bar B, and. secured in position hy means of the lips b, whereby the introduction of dirt beneath the spring is pre-vented, and said spring adapted to beremoved from the hook A without removing the closing-bar, as herein shown and described.
ENOCH GOVERT.
