HORACE B. GHAFFEE, OF NEW` YORK, N. Y.
VISE.
Specification of Letters Patent No. 15,170, dated J une 24, 1856.
T all whom t may concern.'
Be it known that I, HORACE B. CHAFFEE, of the city, county, and State of New York, have invented a new and useful Impro-vement in Vises; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, said drawing being a vertical section of my improvement.
My invention consists in having a supplementary aw pivoted to the back or stationary jaw of the vise, the lower end of the supplementary jaw being connected, by a rod, with a weighted pawl, arranged as will be hereinafter fully sho-wn and described, whereby the pawl is made to catch into the rack which is attached to the lower end of the movable aw, when the jaws come in contact with the article which is to be clamped between them, the pawl serving as a selfacting stop to the rack and enabling the movable jaw to be screwed firmly up against the article to be held or clamped between the,
aws.
J To enable those skilled in the art lto fully understand and construct my invention, I will proceed to describe it.
A, represents the permanent jaw of a vise and B, is the movable jaw, which has a screw C, passing horizontally through it, said screw working in an internal thread in the stationary or permanent aw A. To the lower end of the movable jaw B, there is attached a rack E, which works through a mortise or slot in the lower part of the permanent jaw A. The above parts are con-` structed precisely similar to the ordinary parallel vises, and therefore do not require a more minute description.
To the permanent jaw A, a supplementary Y jaw E is pivoted, as shown at a. The lower part of the jaw E, extends downward nearly to the mortise or slot in the permanent jaw A, and a rod b, is attached to the lower end of the jaw E, said rod passing through a hole or opening o, in the jaw A and connected by a link d, with a pawl F which is pivoted to arms e, attached to the back side of the jaw A. The outer end of the pawl F, has a weight Gr, upon it, and the inner end, when the pawl is raised or moved toward a vertical position, will catch into the rack D. Thus, it will be seen, that when the article I-I to be clamped or held by the vise is placed between t-he jaws E, B, and when the screw C, is turned so that the article is grasped by the jaws, the upper part of the jaw E, will Vbe thrown back and the lower part will be thrown inward toward the jaw B, and the lower end of the pawl will be depressed and will catch into the rack D, as shown in red. The pawl, therefore, thus arranged, forms a self-acting stop for the rack D and allows the jaw B to be screwed rmly up against the article I-I.
Parallel vises hitherto constructed require the stop to be adjusted by hand. A pin is employed which is placed through holes in the rack at the outer side of the jaw A. Other devices are also employed, but they all require to be adjusted when the jaw B is brought up to its work. My improvement obviates this objection, as the stop is perfectly self-acting, the supplementary aw E, throwing the pawl into the rack at the proper time, and the weight G, throwing the pawl from thisJ rack when the jaw E is relieved from pressure.
Having thus described my invent-ion, what I claim as new and desire to secure by Letters Patent, is,
The supplementary jaw E, pivoted to the stationary j aw A, of the vise, and connected with the weighted pawl F, substantially as shown for the purpose set forth.
