SUPPORTING BASE FOR ELECTRIC SCISSORS Filed Feb. 9, 1942 willie/21 777. Codi/1d WifweAS I 7 M I M JV?/ Patented July 13, 1943 SUPPORTING BASE FOR ELECTRIC SCISSORS William M. Collins, Santa Monica, Calif., assignor to The Singer Manufacturing Company, Elizabeth, N. J a corporation of New Jersey Application February 9, 1942, Serial No. 430,113

Claims.

This invention relates to electric scissors and more particularly to supporting bases therefor, and has for one of its objects the provision of a relatively wide base which will support the scissors in an upright position so that they may be readily grasped for use, and on which base the scissors are resiliently supported to reduce vibration and noise when the base rests upon the cutting table.

Another object of the invention is to provide a base which will slide on the surface of the cutting table during the cutting operation to steady the operators hand, thereby making it possible to more readily cut on a marked line, and in which the cutting operation can be stopped at any point on the line and the scissors left in an operative position, relative to the material to be out, so that further operation can proceed with the minimum of effort, and without disturbing the material and the pattern resting thereon.

A further object of the invention is to provide means to deflect the material to be cut upwardly between the blades of the scissors, and to arrange the parts so that the base may be readily removed so that the scissors may be used to cut material that is suspended or draped upon a dress form,

With the above and other objects in View as will hereinafter appear, the invention comprises the devices, combinations and arrangement of parts hereinafter set forth and illustrated in the accompanying drawing of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Fig. 1 is a top plan view of the supporting base.

Fig. 2 is a side elevation.

Fig. 3 is a section taken along the line 33 of Fig. 1 and showing the base attached to the electric scissors.

In the embodiment of the invention selected for illustration, Ill represents a broad flat base made from a piece of sheet-metal, to which one end of each of two longitudinally aligned flat springs II and I2 are secured by means of rivets l3 and M. The free end of the springs are longitudinally slotted or bifurcated at their upper ends as indicated at l5 and I6 to receive the bolts I! and I8 which pass through suitable apertures in the horizontal flange IQ of the adjustable lower blade l9 carried by the depending frame portion 2| and formed with a cutting edge which coacts with the vibratory upper blade 25 of the electrical shears 2| constructed substantially in accordance with the disclosure of U. S. Patent No. 2,047,483, dated July 14, 1936.

Fixed to the base ill by means of the rivets 23 is a V-shaped sheet-metal toe-piece 24 which is inclined upwardly to direct the material between the blades 20 and 25 of the scissors. It will be observed that the front end of the lower blade I!) extends below and under the toe-piece 24 so that a smooth and uninterrupted surface is provided for directing the material to the cutting blades. Adhesively applied to the under face of the base l0, which is adapted to rest upon a table, is av thin sheet of soft rubber 26 and to the lower face of the soft rubber there is adhesively applied a layer of felt 21.

The spring arms H and I2 are sufficiently strong to support the scissors 2| and at the same time to permit them to vibrate freely so that they will not impart vibration and noise to the base 10. The layer of rubber 26 and felt 21 prevents the base from marring the table on which it is placed, and also acts to absorb vibration and noise.

It will be understood that the base Ill is broad enough and the springs II and I2 are so located on the base that the scissors will remain in an upright position at all times so that they may be readily grasped by the user.

The resilient connection between the base and the scissors also permits the operators hand to wobble or tilt sidewise relative to the direction of movement of the scissors and thus allows the base to rest flat upon the supporting surface at all times. Further if the scissors should inad vertently drop from the operators hand or accidentally strike the table or support the shock will be absorbed by the springs thereby preventing damage to the scissors.

Having thus set forth the nature of the invention what I claim herein is:

1. A supporting base member for a pair of electric scissors having an upper and lower blade comprising a fiat base adapted to rest flat upon a supporting surface and having an upwardly inclined toe-piece which is adapted to receive the front end of the lower blade of said scissors and direct the material to be out between the blades.

2. A supporting base member for a pair of electric scissors having an upper and lower blade comprising a flat base adapted to rest fiat upon a supporting surface and having an upwardly inclined toe-piece which is adapted to receive the front end of the lower blade of said scissors and direct the material to be out between the blades, and a resilient member interposed between said base and said scissors.

3. A power operated scissors including a frame, a lower blade mounted on said frame, a vibratory upper blade, a base member, a leaf spring interposed between said base and said lower blade, and means to connect said base member, leaf spring, and lower blade in assel bled relation.

4. A power-operated electric scissors having a frame, a lower blade mounted on said frame, a vibratory upper blade, a broad fiat base member adapted to support said frame and scissors in an upright position and spring means interposed 15 absorbing material applied to its under face,

and longitudinally aligned means on the upper face of said base member for removably securing the electric scissors to the base.
