AMERICUS MERIDA BARNETI, OF ELKTON, KENTUCKY, ASSIGNOR OF ONE- HALF TO JOHN B. WRIGHT, OF SAME PLACE.

SHEARS.

SPECIFICATION forming part of Letters Patent No. 337,917, dated March 16, 1886.

' Application filed December 17, 1885. Serial No. 185,9ll.

To @ZZ whom, it may concern,.-

Be itknown that l, AMnnioUs MERIDA BAR- NETT, a citizen of the United States, residing at Elkton, in the county ot' Todd and State of Kentucky, have invented a new and useful Improvement iu Scissors, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in 1o scissors; and the novelty consists of the peculiar construction, combination, and adaptation ofthe various parts, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

The primary object of my invention is to provide a pair of scissors with detachable and reversible handles to adapt either end of the blades for use, both ends of the said cutting-blades being sharpened orprovided with 2o cutting-edges, whereby when one end of the cutting-blades becomes dulled, through use or otherwise,the handles or thumbguards can be detached and reversed, so as to adapt the other sharpened edges of the reverse ends of the blades for use.

A further object of my invention is to provide novel means for securing the handles to the blades in a secure and iirin manner, and to combine simplicity, strength, and durability 3o of construction with thorough elfectiveness of operation and cheapness ot'mannfacture.

In the accompanying drawings, Figure l is a perspective view of a scissors embodying my invention. Fig. 2 isalike view with thehandles reversed. Fig.3 is across-sectional view on the line a: of Fig. 1. Fig. 4 is a detail view of one of the blades. Fig. 5 is a detail view of the pivoted blades with the handles removed. Fig. 6 is adetail view of one of the detachable handles. Fig. 7is a detailview of one of the handles with apivoted securinglatch.

Referring to the drawings, in which like letters of reference denote corresponding partsiu all the iigures, A B designate the cuttingblades, which are pivoted together near one end, so as to provide a pair of cutting-blades at each end, which are of unequal lengthsthat is to say, the pair of blades a at one end (No model.)

are considerably longer than the blades b at 5o the opposite end. Each of the blades of each pair are tapered or pointed toward their extreme ends, as shown, and they are provided on opposite side edges with sharpened cuttingedges, to adapt either side edge to be used for cutting.

Each of the blades A B is provided with two upwardly-projecting lugs, c c', which are arranged on opposite sides of the pivot b of said blades A B, and extend in the direction do of the longitudinal axis of the blades. Thesi-J lugs are tapered or pointed toward their ends, and on their vertical faces at their bases they are provided with curved orinclined grooves c2, for the reception of the spring-armsdof the 6;, detachable handles D. These handles D each comprise a shank, d', a thumb-guard, cl2, of the ordinary or well-known form, and the spaced-apart spring-arms d, all of which arc preferably formed of one piece of metal for 7o strength and durability. The inner edges of the arms dare curved or inclined to correspond to the shapes of the grooves in the lugs c c, and when it is desired to fit one of the handles D to one of the lugs c or c the ends of the spring-arms are fitted against one ofthe pointed ends of said lugs within the groove therein, and it is then forced inwardly, the spring-arms yielding to the inclination ofthe lugs and closely fitting and encompassing the same within the grooves thereof'.

If desired, the handles may have linger guards or lugs cast or formed thereon, to prevent the fingers ofthe user from being cut by the blades.

The pivotb of the cutting-blades A B may be the ordinary pin,which is headed down on the outer faces of the blades at the ends, or it may comprise a pin having two spring-arms and a fastening wedge or key at one end, this latter device being particularly useful and desi rable when the blades are to be separated for purpose ofsharpening them.

In Fig. 6 I have shown a pivoted latch, E, for locking the handle to the lug c or c ofthe 9: blades, to prevent the accidental detachment of the handle from the cutting-blades and provide a very firm and secure connection be- Ail tween the parts; but in lieu of this latch a spring-catch may be provided for connecting the parts.

The shorterblades,b,are especially designed for cutting button-holes; but if it is found desirable the blades a binay be formedrof .equal length.

1t will be seen from the foregoing description, taken in connection with the drawings,

that when one ofthe pairs of blades a b vhave y I ,tached and reversed, and the-blades very .readily sharpened.

The device is very cheap and strong, is siniple in its construction, and thoroughly ei'etr-ive'forvthe purposes designed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a scissors, the combination, with the pivoted blades having the lugs c c', provided with grooved faces, of thedetachable andreversible handles D, having th'espring1arms d,

to closely fit the lugs, -substantially as described.

2. The combination of the pivoted blades having the lugs, the detachable and reversible handles having the spring-arms, and a pivoted latch carried by the handles, substantially as described.

In 'testimony-that-/Ielairn the foregoing as my own I have hereto aixed my signature in presence of two witnesses. l
