SPECIFICATION forming part of Letters Patent N o. 705,444, dated July 22, 1902. Application filed April 1, 1902. SerialNo. 100,926. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM RICHARD, a citizen of the United States, residing at Bloomville, in the county of Seneca and State ofy Ohio, have invented new and useful-Improvements in Shears, of which-the following is a specification.

My invention relates to shears; and the object of the same is to construct an improved device of this character which will always remain tight and be elastic'in its action and be provided with means for adjustment.

The novel construction' employedby me in carrying out myinventionisgfully described in this specification and claimed, and illustrated in the accompanying drawings, forming a part thereof, in which- Figure 1 is a plan View of my device. Fig. 2 is a detail of the bolt. Fig. 3 is a longitudinal section through the bolt on the line 3 3, Fig. 1. Fig. 4 is a detail of the spring. Fig. 5 is a detail of the nut. Fig. l6 is a detail of a modified form. Fig. 7 is a detail of thel washer.

Like numerals of reference designate like parts in the dierent views of the drawings.

The numeral 1 designates one blade of a pair of shears, and 2 the other blade. These blades are apertured at 3 and are secured together by a bolt 4, having a head 4a. A slot 5 is cut in the bolt, and a small rigid pawl 6 is formed in one end of the'slot. spring 7, having diverging arms 7a, is mounted in the slot 5 and bears a rack 8 on one arm 7 a, which rack is engaged by the pawl. A.

groove 9 is formed in the blade 2 and is e11-l gaged by the arm 7a to prevent its being de. ranged when operatin g the shears. From the construction shoWn fit is obvious that the pressure between fthe bladesrl and 2 can be blade 2.

A' V-shaped' regulated by changing the position of the spring 7.

In the modified form illustrated in Fig. 6 a bolt 10 is employed having a head 10a and a threaded shank 101. A rubber washer 11 is slipped on the bolt and ts snugly against the A spiral spring 12 surrounds the bolt 10 and bears on the washer, and a nut 13, having a concave face 13, serves to hold the spring 12 in place. The force of the spring 12 can be regulated by the use of the nut 13.

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having thus described umyinvention, what I claim asnew, and desire to secure by Letters Patent, is-

1. In a pair of shears, the combination with a pair of apertured blades, one of said blades having a groove thereon extending transversely the aperture therein, of I a bolt pass- 'ing through said aperture, saidl bolt having a slotted shank bearing a'pawl, and a V-shaped spring Ibearing a rack and mounted to engage said pawl and said groove, substantially as described.

2. In a pair of shears, the combination with two apertured blades,of a bolt passingthrou gh said apertures, said bolt having a slotted shank bearing a pawl, and a V-shaped spring bearing a rack engaged by said pawl, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses. i

WILLIAM RICHARD. Witnesses:

C. A. WEIDAN, J. S. CARLIN.
