UNITED STATES PATENT OFFICE.

WILLIAM B. COULTER AND JOHN CHURCHILL, OF BRISTOL, CONNECTICUT.

THUMB-NUT.

SPECIFICATION forming part of Letters Patent No. 244,379, dated July 19, 1881.

Application filed February 19, 1881. (N0 model.)

To all whom it may concern:

Be it known that we, WILLIAM B. COUL- TER and JOHN CHURCHILL, of Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Thumb-Nuts; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in thumb-nuts.

Heretofore th uinb-nuts have ordinarily been made of cast-iron, the nut portion of which is first drilled and then tapped. This construction of thumb-nut is expensive, owing to the time, and expense required in drilling and tapping the cast-iron; and the object of our invention is to obviate these objections and difficulties met with in the manufactureof thumb'n'uts.

With these ends in view our invention consists, essentially, in the combination, with a nut, of an inclosing-shell provided with'thumbprojections, said shell being firmly secured to the nut.

Our invention further consists in certain features of construction, as will hereinafter be described, and pointed outin the claims In the accompanying drawings, Figure l is a view, partly in side elevation and partly in vertical section, of a bolt having our improved construction of thumb-nut applied thereto. Fig. 2 is a view in perspective of the shell or casin g which is applied to the nut. Fig. 3 is a plan view of the under side of the shell or cas- Fig. 4 is a view in perspective of the complete thumb-nut.

A represents an ordinary wrought-metal nut, and B the bolt to which the nut is applied.

The nut A is transformed into a thumb-nut by applying thereto the shell C, which is preferably made of malleable cast-iron, though it may be made of other material, if desired. The shell or casing C is composed of the fiat sides a, which fit against the sides of an ordinary nut, and the bottom. b, upon which the nut is seated, said bottom portion being perforated at c for the passage of the bolt. Two sides of the shell 0 are provided at their upper edges with the prongs or projections d, of any desired form, size, and number, which are bent over against the upper face of the nut, and thus retain it against displacement. The shell has thumb-pieces e 6 cast solid therewith. Thus it will be observed that the ordinary form of nut may be quickly transformed into a thumbnut at very slight expense. The inclosing shell 0, having a firm bearing on the sides and V the upper and lower faces of the nut, is firmly held in place, and is equally as durable as if made integral therewith. The shell may, of course, be made to fit a nut having any number of sides. Again, we would have it understood that we do not confine our invention solely to thumb-nuts, as a hand-wheel with but one Wing or handle on it may be made in the same manner and would fall within the scope of our invention.

Itis evident that slight changes in the form and construction of parts might be resorted to without departing from the spirit of our invention, and hence we would have it understood that we do not restrict ourselves to the exact form and construction of parts shown and described; but, Having fully described our invention, what we desire to claim as new, and secure by Letters Patent, is-

1. An in'casing-shell provided with a receptacle for a nut, an opening for a bolt, wings, (one or more,) and projections adapted to be bent over against one face of the nut and secure it against displacement, substantially as set forth.

2. The combination, with a nut, of an inc-asin g'shell provided with thumb-pieces or proj ections and furnished with projections or prongs which are bent over against one face of the nut, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 15th day of February, 1881.
