of Washington, have are like in construction, hand- grip members 10 and 20 respectively To all whom it may concern: Be it known that I, THoMAsK. Preeo'rr, a citizen of the United States, and resident of the city of Seattle, county of King, State invented certain new and useful Improvements in Shears with Detachable Cutting-Blades, of which the following is a specification.
y invention relates to shears, and consists of a novel construction wherein the shears are provided with detachable and renewable blades, whereby the blades may be made of. a high quality of material and removed for sharpening or for replacement, and whereby the quantity of high quality steel required is reduced to a minimum.
The object of my invention "is to provide a construction whereby the cutting members may be made of thin sheet steel of high quality, which cutting members are removable as 'above stated.
Myhnvention comprises the novel features which will be'hereinafter set forth and then particularly defined by the claims;
In the I accompanying drawings I have shown my invention in the form of construction which is now most preferred by me. Figure 1 is a side view of a pair of shears made in accordance with my invention, the same being shown in a partly open position. Fig. 2 is a perspective view of one of the blade frame members. Fig. 3 is a corresponding perspective" of one of the thin steel blades which. constitute the cutting elements. Fig. 4 is a section on the line 4+4 of Fig. 1.- The frame of the shears is composed of two members, 1 and 2, which in the main each consisting of and blade members 11, 11, these'being pivoted by theusual pin 12.
The hand grip members 10, 20 and the part of the frame at that side of the pivot suitable construction. These need be made special in construction only as is hereinafter stated. Each of the arms 11 1s provided with a groove 13 extending lengthwise thereof in one side face, which one which is outermost when closed. Adjacent the hole the pivot pin 12 each blade is recessed for the reception of th corre sponding portion of the plate, which forms the cutting member.

frame, so as to, resist LE CUTTING-BLADES.
Patented Dec. 12, rate. 1916. SerialNo. 78,315.
The cutting members, one of which is shown in perspectivein Fig. 3, consists of a thin plate of sheet metal having a section 4, which 'orms-the face of the blade of the shears which is inward orfaces the companion blade. This extends along the corresponding face of the arm 11 and at the back edge thereof is bent to form a channel 40 back edge of the which closely embraces the frame bar or arm 11. The plate is then bent backward or toward the cutting edge 42 to .form a slight flange 41 which enters ther'ecess 13 of the frame bar 11. The plate 4 is put in place upon the arm 11 by, sliding the same lengthwise thereof. The main section 4 of this cutting vided with lugs 43, ward so as to engage member may be prowhich are turned upthe inner edge of the .arm 11 thereby assisting to sustain the strain produced by the cutting action. The inner end of the flat section 4 of the cutting member extends beyond the pivot of the shears, and is provided with a hole 44 for the reception of the pivot bolt 12.
By this expedient the parts are held against removal "as long as the pivot bolt or pin 12 The inner end of each plate 4 is provided with a notch 5, which notches are so disposed that when the shears are open, an opening is provided as shown in Fig. 1, into which may be inserted any small object which it is desired to out, as for instance a wire. This'p'rovides a means for cutting such objects outside of the ordinary. cutting edges'of the shears,and placed at a point that the leverage conditions are favorable. The oppos'iteedges of the plates 4 are also well supported by the ledges 22 of the the strain.
It is,obvious that with such a type of construction th cutting element may be made of thin sheet steel of a high degree of temper, 7 parts which are strong and not liable to be broken. The main frame would be cheap in construction, and it would be possible to remove the cutting blades for sharpening,- and to substitute therefor another set at any time desired. This makes it possible. to keep the shears in good repair.
The cutting elements may also be made of a much higher grade of material than it is while the frame may be made of I struction.
What I claim as my invention is:
1. A shears comprising pivoted frame members, each having a cutting members bent to embrace blade-carrying bar, the back 5 of the blade-carrying bars and terminating at this edge in an inwardly extending flange,
bars having a slot ng pivoted frame blade carrying bar,
cutting members bent to embrace the back of the blade carrying bars and terminating at this edge in an inwardly extending flange, the blade carrying bars having a slot receiving said flange and the blades having lugs engaging the front edge of the blade carrying bars.
Signed at Seattle, Washington, this 3rd day of February 1916.
