CARL A. SHULTZ, OF KANSAS CITY, 'MISSOURI BUTTONHOLE-CUTTER.
SPECIFICATION forming part of Letters Patent No. 512,452, dated January 9, 1894. Applicationtiled December 19, 1892. Serial No. 455,727. (No model.)
To LLZZ whom, t may concern.-
Beit known that I, CARL A. SHULTZ, a citizen of the United States,residing at Kansas City, in the county of Jackson 'and State of Missouri, have invented certain new and useful Improvements in Buttonhole-Cutting Attachments for Scissors, of whichl the following is a speciiication, reference being had to the accompanying drawings, in which- Figure 1 is a side view of a pair of scissors carrying myimproved attachment. Fig. 2 is a vertical section on line 2 2 of Fig. 1; and Fig. 3 is a section on line 3-3 of Fig. 1.
My invention relates to devices for cutting button-holes in cloth.
Heretofore button-holes have been cut by means of a pair of scissors manufactured eX- pressly for that purpose, which scissors are commonly known as button-hole scissors.
The object of my invention is to provide an attachment which may be applied to scissors 0f the ordinary form, and which will adapt them for use in cutting button-holes, thereby avoiding the necessity of providing scissors of special construction. I accomplish. this object as hereinafter specified and as illustrated in the drawings. That which I regard as new will be pointed out in the claims.
In the drawings,-l indicates apair of scissors, having blades 2 and 3.
4 indicates a plate which is adapted to be attached to one ot' the scissors blades, as 2, and is provided with a cutting edge `5 which lies in position to engage the cutting edge of the opposite blade, as 3. In order to permit of regulating the size of the button-hole to be cut, the cutting edge 5 is arranged at an angle to the opposite blade 3, as shown in Fig. 1. The plate 4 is secured upon the blade 2 by means of a clamp 6, which as here shown is formed by bending one end of the plate 4 over upon itself and securing it to the main portion of the plate by means of an adjusting screw 7, as best shown in Fig. 2. I do not wish to limit myself, however, to this specific construction, as other methods of securing the The blade 2 of the scissors is designed to pass through the clamp 6, and the plate 4 is securely held in place by means of the screw 7 By this arrangement the position of the plate 4 upon the blade 2 may be adjusted as desired, and
the plate may be readily removed. At the inner edge of the plate 4 is provided a needle 8, which projects beyond the cutting edge 5 of said plate, as shown in Fig. 1. The needle 8 is fitted into a groove in the edge of the plate 4, and is securely but detachably held in place by a link 9 which passes through a slot 10 in the plate 4 and around the needle as shown in Figs. 1 and 3. The slot 10 lies at an angle to the edge of the plate 4, by which arrangement, by moving the link 9 in the slot it may be made to clamp the needle tightly in position or to release it. The length of the cutis regulated by a stop 1l, which consists of a bolt fitted into an inclined slot l2 in the plate 4, as best shown in Fig. 1. The bolt is held in position by a nut 13, as shown in Figs. 2 and 3. The slot 12 is so arranged and the stop 11 is so placed that as the scissors blades close the blade 3 will come in contact with the stop 11 and its motion will therebybelimited. Byadjustingtheposition of the stop 11 in the slot 12 the distance which the blades will travel before being stopped will be varied. The stop-adjusting slot 12, is arranged atan angle to a perpendicular line drawn from the cutting edge of the plate 4, whereby the required adjustment of the stop 11 can be eected without increasing the length of the plate, as would be essential for the purpose if the slot were arranged perpendicular to the cutting edge of the plate. The angle of the slot may be varied and if desired may be made substantially parallel with the cutting edge of the plate and this will accomplish the result above set forth, of obtaining the required adjustment of the stop without increasing the length of the plate.
The use of the needle 8 permits of accurate cutting, as the point at which the cutting is to begin may be very accurately determined.
The thumb screw 7, by means of which the sleeve 6 is secured upon the scissors plate, also serves to move the plate 4 laterally to adjust the position of the needle 8, as the portion 6 of the plate 4, which 4constitutesthe clamp or sleeve, is made somewhat stiier than the main portion of the plate 4 to permit of such adjustment.
As shown in Fig. 1, the inner edge of the plate 4, to which the needle 8 is attached, is slightly concave, by which construction the IOO temper of the needle serves to hold it in contact with the outer edge of the plate 4, the base of the needle being held firmly in position by the link 9, as above described.
The attachable and detachable needle is advantageous in that it can be removed and sharpened independent of the plate 4, thus avoiding the danger of injuring the cutting edge of the said plate, and further if the needle is broken it can be replaced by a new one it is more easily controlled than a needle formed with the plate, and the cutting attachment is generally more useful and durable with a detachable needle than Where a permanent needle is used, since breakage of the permanent needle renders the attachment useless.
By the construction of the cutter-plate 4, and the arrangement ot' the screw 7, the position of the needlepoint may be altered relatively to the cutting edges of the scissors blades 2 and 3, by the action of the screw. The elasticity of the metal composing the plate 4 is such that when the screw 7 is turned to loosen the clamp the point of the needle will be moved in one direction, whereas it' the screw is turned in the opposite direction the point of the needle will also be moved in the opposite direction.'
That which I claim as my invention, and desire to secure by Letters Patent, is-
1. A button-hole cutting attachment for scissors, consistingof a plate having means to secure it to one blade ofthe scissors and provided With a cutting edge, and a needle detachably secured to the plate for determining the point at which the cutting commences, substantially as described.
2. The combination in a button hole cutting attachment for scissors, of a plate having a cutting edge and bent round at one end to embrace one blade of the scissors, a thumb screw adj ustably connecting the bent end of the plate with the body thereof for clamping the plate to the scissors blade, and a point projecting from the cuttingedge of the plate for determining the place at which the cutting commences, substantially as described.
3. The combination in a button hole cutting attachment for scissors, of a plate 4 having an inclined stop-adjusting slot 12, a cutting edge 5, and a clamp for securing it to a blade of the scissors, and a stop 1l extending through and adjustable along the slot of the plate, substantially as described.
4. The combination in a buttou-holecutting attachment for scissors, of a plate 4 having an inclined stop-adjusting slot 12, a cutting edge 5, and a clamp for securing it to a blade of the scissors, a stop ll extending through and adjustable along the slot of the plate, and a screw-nut engaging the stop for clamping it in any desired position in the slot, substantially as described.
5. The combination in a button-hole cutting attachment for scissors, of a plate 4 having a cutting edge 5, and means for securing it to a blade of the scissors,adetachablc needle 8, and a link 9 carried by the plate and embracing the needle to detachably secure the latter in position, substantially as described.
