IMPROVEMENT IN COMBINATION TOOLS.

Specification forming part of Letters Patent No. 132,90, dated November 12, 1872.

To all whom it may concern: y

Be it known that I, DAVID HEATON, of the city and county of Providence and State of Rhode Island, have invented a new and useful Improvement in the Combination Tool known as The Household Implement,77 and patented by Thomas Garrick May 9, 1871, of which the following is a specification, referring to the accompanying drawing making part of the same, in which- Figure lis a front view of the improved construction of said implement; Fig. 2 is a side view of the same and Fig. 3 is a view of the reverse side. Y

Similar letters mark like parts in all the figures.

My improvement consists in constructing the said implement, as herein shown and described, with a sliding clasp for coniining and holding the movable jaw of the adjustable wrenchiirmly in position parallel with the lixed jaw while in use.

The said implement is in two parts, A and B, which are separable for the use of either by itself, or co-operatively with the other, as for the purpose of a screw-driver, S, in the first instance, or as a hammer, H, and carpet-stretcher J, or box-opener B, in the second instance. "When, however, the two part-s are connected together a very convenient adjustable wrench is formed by the sliding of the movable jaw D toward or from the fixed jaw F on the part A. .This is accomplished by the engagement of one or more teeth ofthe movable par-t with the set of equidistant teeth f on the iixed part A,

and in order to make the said wrench more effectual anduseful I make the teeth with one perpendicular side and one inclined side as better adapted to resist the strain, and for the purpose of the better dividing the space into equidistant openings for the jaws to receive the different standard sizes of nuts; and I further provide a sliding adjustable clasp, C, which slides upon the inclined surfacei ofthe movable jaw and on the straight under surface g of the fixed-jaw part A, and by so doing firmly embraces and holds the two parts A and B together, and both prevents Vthe jaws from slipping and gives additional strength to the parts without requiring the forcible gripe of the hand upon both handles, as in the former construction without said clasp.

Vhen not in use the clasp rests, in the position shown in Fig. 2, against the projection k, Fig. 3, when the part B may slide freely on the part A, or the two parts be separated; but when the jaw D is set in the required position to fit upon the nut, by simply sliding the clasp firmly into the position shown by dotted lines in Fig. 3 the jaw D is held rigidly in place, as :much so as if the two jaws were solidly united together. l

I claim- In the construction of the implement, as shown, a sliding adjustable clasp, O, as and for the purpose specified.

DAVID HEATON.
