To all/ whom tracy concern.:
Beit Imaan that L EliwAeD A JGHNSQN,
a citizen vof thefUnited States, residing at Enid, in the countyfof Gareld andl State of Oklahoma, hare invented certain new and useful improvements in Shears, of which the following is a. speciiiation.
My invention relates to new and useful improvements in cuttingK shears, and as its principal object aimsgto `provide a pair. of shears, the cuttingblades ofwhich consist of sleeve members which are slidably mounted on pivoted jawsa'nd'are adjustable, whereby they may be employed inthernanner of ordinary cutting shearsl or may loe quickly converted to perform the oiices of button-hole scissors.
A further object is to provide in connection with the sliding sleeve blades a graduated scale upon which may be read the dis`A tance inwardly from the edge of the cloth or garment at which the button hole will be cut.
An object of equal importance with the foregoing is to construct the shears of this invention with such regard to number, `prioportion and arrangement of Aparts that they may be cheaply manufactured, will be durable and eicient in their action, and may be easily and quickly converted to serve either as ordinary cutting shears or as button-hole scissors.
The above and additional objects are accomplished by such means as are illustrated in the accompanying'drawings described in the following specification, and then kmore particularly pointed out in the claims which are appended hereto and .form a part ofithi's application.
With reference to the drawings, wherein there has been illustrated the preferred embodiment of this inyention as it is reduced to practice, and throughout the several views of which similar reference numeralsdesignate corresponding parts,
Figure l is a perspective view showing my invention with the blades in open position;`
Fig. 2 is a side elevation, showing the blades in open position. ln this figure the elevation is taken from the opposite sideA of the scissors from Fig. l; llig. 3 is a section on the line 3 3 of Fig. l; lig. t is a longitudinal section taken through the blades with these members in closed position; Fig. 5 is-,a detail perspective View of one of the remoyable sleeve blades; and Fig. 6 isa detail perspective lview of the blade vreceiving armsof the scissors. in openposition.
rilhe shears embodying my invention include apeir of-blade receiving arms l0 and l1, which are `.enlargeclat one end to produce theterminal plates l2 and 13, respectively. These members 12 and 13 are pivot-ally united byan ordinary screw or similar element, indicated at le;
Handles of the well known 4type are formedon the terminal plates l2 and 13, as indicated, at l5 and '16, respectively.y
The blade receiving arms l0 and ll are, as best shown in Fig. 6, reduced in width and in thickness toward their free terminals, producing the three sections A, E and C. lt will bessenI that thesections A. of the arms '10 and il arevof'less width and thiclrness than the plates l2 and i3, andthattheir outer faces are spaced from the outerfaces of the members l2 and i3, while their inner ness than the section l5, there are formed at 4 the junction of these sections the shoulders i8 and 18. lt will further be seen that inasmuch as the sectionB is of less width than the section A, and the section C is of less width than the section B, there .will be formed at the junction of the longitudinal edges of the sections the shoulders 182 and 183. rlhese various shoulders are formed on the. armsl andll in order to abut similarly formed internal 'shoulders of the. cutting blades so that the blades will belirnited in their. sliding. movement on thereceiving arms, and mayA he properly positioned thereon.
These cutting blades, individually designated in Figs. l and 2 by the numerals 19 and 20, Vare formed of tempered sheet metal, although they may, of course, be cast if this method be found more desirable and cheaper. As stated, these blade members i9. andl @02ers formed in thenatnreofsleeves,
each including, as best illustrated in Fig. 5, side walls-21 and 22 vand a cover flange 23. The side walls 21and 22 are tapered or reduced in width toward-their forward ends so that the channels defined by the side walls 21- and 22 and top flange 23 are restricted toward the forward terminals of the blades, whereby the sleeves may be snugly fitted on the blade receivingA arms and 11, as shown in Fig. 3 particularly.
It will be noted upon reference to Fig. 5 that the channels which are formed in each of the blade members are' so reduced toward the foward terminals of the blades that they form three chambers D, E and F. It will also be seen that the chamber E is less in width than the chamber D, while the chamber'F is of less width than the chamber E. There are thus produced threeA chambers, each corresponding in outline to the shape of the sections A, B and C of the blade receiving arms. reference particularly to Figs. 1 and 2 that the shoulders 18,18', 182 andr183. all abut corresponding shoulders which are formed at the juncti'onsof the three chambers D, E and F, which are defined by the side walls 21 and 22 and top Aflange 33 of the blades.
The lower edge of the side wall 21 vis. slightly beveled, as indicated at 24, so that a sharp cutting edge 25 will be formed at the yjunction of themembers 21 and 22. It
may-be well to explain at this point that the sleeve members or cutting blades 19 and 85 rial so that, when placed on the arms-10 and 11, they will grip thesejmembers, being thus held against wabbling or shifting during the manipulation of the scissors.
A's ameans for holding the sleeves'19 and 20 in position on`the arm members 10 and 11, .the wall 21 of each sleeve member carries a rearwardly extending attaching vplate 26 which issubstantially rectangular, in shape, and is formed at the upper edge portion of the member 21, as best shown in Fig. 5.
This member 26 is longitudinally slotted, as
indicated at 27, so that it may receive a set- -screw 28 which is vthreaded in the member 12 or 13, as the case may be. The ange 23 extends along the upper edge of the member 26, and engages the upper edge of the terminal plates 12v or 13, depending',- of course, uponl which arm receives the particular cutting blade.
When the shears are to be used as are ordinary cutting shears, the cutting sleeves 19 and 20 arel positioned on' the arms 10 and 11 yso that the rear edges 30 and 31 of the B0 inner walls 21 of-the two sleeves 19and 2O engage againstthe shoulders 17. The setscrews 28 are then threaded into the members 12 and.13 to iirmly bind or clamp the attaching plate 24 thereagainst. The cutting sleeves or blades being thus held in It will be noted now upon' 2O are formed of relatively resilient matesl position on the pivoted -arms 10 4 and 11, the operator may usethe shears in the usual manner by grasping the handles 15 and 16.
Should it be desired, however, to quickly convert the shears into button-hole scissors,
it is only necessary to slide the sleeves forwardlyY on-the arms 10 and 11 so that the rear edges 30 and 31' ofthe sleeves will be spaced from the shoulders 17 of the arms 10 and 11. When the blades are -thus positioned, as shown'in Figs. 1 and 2, it will be readilyseen that the rear points or corners 32and--33 of the blades may be eliciently employed incutting button-holes.
It is, of course, desirable to provide mea'ns- 'may be threaded intoor out of the member 13 to vary the length f the cut which may lbe made by the rear edges or corners 32 and 33 of the' blade.
-As a means for enabling the operator to determinethe distance from the edge of the cloth or garment at which the vbutton-hole will be cut, the lower edge of each attaching plate 26 is provided with a graduated scale which, when read in connection with the arrows embossed or otherwise formed `on the members 12 and 13, as indicated at 36, indicate the distance -which separates the rear edges 30 and' 31 of the blades from the shoulders 17. Inasmuch as the operator will pass the edge of the garment in between the blades until the edge engages with the shoulders 17, it is obviousY that the distance of the proposed buttonholefrom the edge of the' cloth'or garment may be readily ascertained by means of the graduations onthe members 26.
From the foregoing description, it will be noted that I have provided a pair of scissors which may be quicklyA and easily converted into button-holescissors, and further that a new and sharp pair of cutting blades may be substituted for' worn-'out blades by merely removing the screws 34. Inthis manner, the user of the shears may always have a sharp instrument,and may send the dull or worn-out blades to be re-sharpened in the same manner as do users of safetyrazors.v
In reduction to practice, it has been found l that the form of this invention illustrated in the drawings, and referred to in the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, Without sacrificing any of the advantages of this invention, as defined in the appended claims.
