Application {iled October 3', 1905.V Serial No. 281.1Il8.

Be it known that I, WILLIAM Pnn'iiMAN Brame, a citizen of the United States, and a resident of Moberl in the county of Randolph and State o Missouri, have invented new and Improved Shears, of which the following is a full, clear, and exact description.

This invention relates to shears and it consists, substantially, in the details of construction and combinations of parts hereinafter more particularly described, and pointed out in the claims. Y

The invention has reference more es ecially to shears for cutting or trimming bo ts, wires, wire nails, and the like; and one of the princi al objects of the invention is to provide s ears of this kind of an embodiment to overcome numerous disadvantages and objections encountered in the use of many other shears of the kind hitherto devised.

-A further object is to provide shears ofthe character specified which is simple in construction and comparatively inexpensive to manufacture besides being thoroughly effective and reliable in use and possessing the capacity for long and repeated service.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, in which- Figure 1 is a side view of shears embodying my improvements, and Fig. 2 is a view of my im roved shears looking at the saine from eit er side of Fig. 1, the full lines indicating the closed position of the handles and blades and the dotted lines the open position thereof.

Before proceeding with a more detailed description it may be stated that in the form of my improvements herein shown I employ shears of the character referred to comprising specially-constructed' handles or levers having special cooperating movable fulcra, together with special connections at such fulcra for maintaining the desired relation therebetween. Specially-constructedblades are employed for the shears, having the inner ends thereof in movable relation with the corresponding ends of the handles or levers, the opposite edges of the blades or levers being parallel and beveled or sharpened for a suitable proportion of length of the blades or levers from their outer ends, special means being employed for maintaining the cutting portions of the blades or levers in movable relation with each other.

Reference being had to the drawings by *y of one of the blades 7 of the shears.

'the designating characters thereon, 1 represents ymy improved shearsin entirety, the same comprising handles or levers 2, which are curved outwardly from each other in the 'direction kof the free ends thereof, asshown, j

such ends being provided with grips or handgrasps 3 for enabling the operator to grasp the shears for the purpose of manipulating the same. Theinner ends of said handles or levers 2 are formed with short arms 4,

lied to one of them, are divergent, as s own in ig. 2, each of said arms being provided with integral par-allel jaws 5a, spaced from each which when the handles or levers 2 are brought l 'together as far as permitted by a sto 5, ap-

other for a suitable distance and supporting between them a pin or rivet 6, on which is loosely or pivotally mounted the inner end The inner ends of the blades are normally slightly divergent in the direction of the handles or levers, while for a suitable distance from the outer ends of said blades the inner or opposite parallel edges 8 thereof are beveled or sharpened for the purpose of eecting the cutting or trimming of bolts, Wires, and similar metallic objects, as will presently be explained. Also for a suitable distance from the outer ends thereof the blades 7 are movably connected together at either side by means of parallel links 9, said links being themselves connected together by means of l pins orrivets 10, extending through suitable openings therefor in the said blades 7.

The inner ends of the handles or levers 2 are rovided with cooperating intermeshing toot ed segments 11, the teeth of which engage each other, as shown in Fig. 2, said segments constituting practically movable fulcra between the said handles or levers 2. Parallel links 12 are employed for movably connecting together the inner ends of the handles or levers 2, so as to maintain the toothed segments in operative relation to each other, these parallel links 12 being themselves connected together by means of pins or rivets 13, passing through suitable openings therefor in the segments and constituting practically the working centers for said segments.

The stop 5 for limiting the extent to which the handles or levers 2 may be brought together in operation is preferably provided with a set-screw 14, so as to enable adjustment thereof to be made in conformity with thev widening of the normal distance between ICO IIO

. in parallelism, as shown in dotted lines in Fig.

2, thereby causing the blades '7 to swing upon the centers provided therefor by the pins or, rivets 10. In this way the cutting edges of the blad es are caused to be separated a suiiicient distance to enable the bolt, wire, or other object to be inserted therebetween for the purpose of trimming or cutting off the same, as may be desired. To effect the cutting of the object, the handles or levers 2 are carried together with a sufli- .cient amount of force, whereupon the operation of the parts is caused to take place reversely to that first above described, as will be readily understood.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. Shears, comprising handles having intermeshing teeth and pivotally connected Awith each other intermediate of their ends,

and blades pivotally connected with each .other and with the inner ends of the handles.

2. Shears, comprising handles having intermeshing teeth and pivotally connected with each other intermediate of their ends, and blades pivoted to the inner ends of the handles and having a link connection with each other adjacent their cutting edges.

'3. Shears, comprising lever-handles having intermeshing toothed segments, links pivotally connecting the lever handles, blades pivoted to the inner ends of the leverhandles, and links pivotally connecting the blades, adjacent to the cutting edges thereof.

4. Shears, comprising lever-handles provided adjacent to their inner ends with intermeshing toothed segments, parallel links pivotally connecting the inner ends of the lever-handles, blades having diverging inner ends pivoted to the inner ends of the leverhandles, and parallel links pivotally connecting the outer ends of the blades.

5. Shears, comprising lever-handles having intermeshing teeth and pivotally connected with each other intermediate of their ends, blades pivotally connected with each other and with the inner ends of the leverhandles, and an adjustable stop on one of the lever-handles.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
