To all whom it may concern.

Be it known that I, Nnnrm O'HENAULT, a

citizen of the United States, residin at' Butte, in the county of Silver Bowfand tate of Montana, have invented certain new and useful Improvements in Milliners. Shears;

and I do declare the following to be a full,

' clear, and exact description of the invention,

such as will enable oth'ers skilled in the art 10 to whichit appertainsto make and use the same.

My invention relates to improvements in milliners shears, such as those shown in my U. S. Patent Nos. 617,018 and 1,432,246. The shears shown by each of these patents corn.-

prise briefly a pair ofpivoted blades, apalr of handle-carrying shanks projecting rearwardly" beyond the blade pivot, a pair of needle-gripping lu'gs carried by the'handles, a

lateral enlargement on' one of the shanks, and

a forwardly projecting lug carried by this enlargement, the other shank being receiv able between the last lug and the first-named shank when the handles are moved toward each other. One object of the present invention is to improve upon shears of the general type above setfforth, by providing the inner side of the last-mentioned lug'with a cam which. co-operates with, the" shank; above identified as the .other shank, for the I purpose of'contracting tubular clasps which are used in making hat-frames, for the purpose ofconne'cting the ends of certain stifi wires, used principally in reinforcing wide hat brims. The camand the other shank press oppositely against the clamp when the latter is inserted between them, and a further object of the invention is toprovide co-acting cam surfaces on the handle-carried lugs,

40 which surfaces are operable to force one shank laterally with respect to the other,

thus forcing the clasp-contracting lugs and.

the co-acting shank V tightly toward each other during the contracting operation of the clasp. These co-actin'g cam surfaces on the handle-carried lugs are also of great advantage in gripping needles to pullthem through the work, to remove them from or apply them to a sewing machine, for grasping numerous other articles used in the art of hat making. and for holding the points of the blades against each other when using such points.

With the foregoing objects in view, the in vention resides in the distinct improvements hereinafter fully pointed out and claimed,

a and illustrated in thejaccompanying draw lngs.

Figure l'is a perspective view showin'g the shears opened and a wire-connecting clasp about to be engaged'with the cam of the claspco'ntracting lug; V

Flg. 2 1s a View similar to Fig. 1 but 11- blades pivoted together at 2 and provided with shanks 3 and 8 pro'jectingrearwardly beyond the pivot, said shanks carrying han dles 4 and 4 At 5 and 5 wire receiving and bending grooves are shown, and at 6 and 6" wire cutters have been illustrated. V The shank3 is vprovided with a lateral enlarge ment 7 in "the inward pathof the shank 3 and a lug 8 projects forwardly from said enadjacentinner side of the shank 3 so that the shank 3 is easily receivable between the two. Short necks 10 and 10? project rearwardly from the handles 4 and t 'and are provided with "co-operable lugs 11 and 1 1%v The general structure above described. is substantially shown in the patents above re- I ferredt 'but the lug 8 has been made much heavierto resist strain to which it is'now subjected, and the formationof the lugs 11' and 11 have been improved, as hereinafter. set fortln Formed in the inner side of the lug 8, is a 'largement .7, saidlug being spaced from the V transverse, preferably v-shaped groove-9' which opens through the upper edge of said lug and preferably decreases gradually in depth toward its lower end. This groove constitutes a cam which is adapted tocooperate 'Wlth', the adjacent portion of the shank 3 to contract a tubular clasp O, for connecting the ends-of wires W. In perform- 7 I ing this operation, the wire ends are insertedinto'the clasp and this clasp is disposed between the lug 8 and the adjacent portion of the shank 3, as illustrated in Fig. 1, the clasp being then positioned in'the groove 9. When the shears are now closed, a portion of the shank 3 co-operates with the cam 9 in exerting inward pressure on opposite sides of the clasp, thus effectively contracting .the latter to bind it tightly upon the ends of the wires.

For the purpose of forcing the shank 3 toward the lug 8 and vice versa, when a clasp is being contracted, I form the lugs 11 and 11 with oblique cam surfaces 12 and 12 shown more particularly in Fig. 4. These surfaces contact with each other before the shears have completed the contracting operation upon. the clasp, but they do not come into appreciable contact until after the blades 1 andl have almost closed.

Thus, while the cam surfaces'in question will not interfere with proper operation of the blades land 1, they will force the shank 3 toward the right and the shank 3 toward the left, thus exerting sufficient pressure against the clasp C to insure its efiective contraction. The surfaces 12 and 12 are also co-operable' with each other to hold the points of theblades against each other when cutting with said points, and are useful for the purpose of grasping needles or any other articles, such as pieces of wire used in making hat frames. The angular relation of the surfaces in question, with respect to the shears, is such that said surfaces may be very conveniently used for a number of purposes, one particular adaptation, being for the removal and insertion of sewing-machine needles.

It will be seen that I have distinctly improved upon shears of the type covered by my previous patents. Excellent results may be obtained from the construction shown and it is therefore preferably followed, but within the scope of the invention as claimed,

minor changes may be made.

I claim: 7

.1. An improvement in 'milliners shears having pivoted blades, handle-carrying shanks extending rearwardly be 0nd the pivot of the blades, a lateral en argement on one shank in the inward path of the other shank, and a forwardly projecting lug on said enlargement between which and said having pivoted blades, handle-carrying. H

shanks extending rearwardly beyond the pivot of the blades, a pair of co-operable lugs projecting rearwardly' from. the handles, a lateral enlargement on one shank in the inward path of the other shank, and a third lug projectingcforwardly from said,

enlargement in, spaced'relation with said one shank'to permit reception of said other I shank between the latter and said third lug; said improvement comprising a cam at the inner side of said third lug to co-act with said other shank 1n contracting a tubular .Wlleconnecting clasp, and a pair of oblique cam faces on said co-operable lugs, said cam faces being co-active in forcing said second shank toward said thirdlug when clasp is being contracted, and in grasping needles and other articles.

4. An improvement in shears having crossed pivoted blades, handle-carrying shanks projecting rearwardly beyond the blade pivot, and co-operable lugs extending rearwardly from the handles; said improvement comprising co-acting cam surfaces on said lugs active to laterally'shift the blades and handles andhold the points of the former against each other.

In testimony whereof I have hereunto afiixed my signature. 7
