SPECIFICATION forming part of Letters Patent No. 542,183, dated July 2, 1895.

A lidatio fi November 3,1894. Seria1No.52'7,787- (No model.)

Be it known that 1, RUFUS PUTNAM Bow DOIN, a citizen of the United States, residing at Wilmington, in the county of New Hanover and State of North Carolina, have invented a new and useful Scissors, of which the following is a specification.

This invention relates to an improvement in that class of scissors wherein means are provided for imparting to the blades a draw, to the end that they will be capable of cutting the material with which they are used upon the application of less power, and also regulate the blades in their movements.

to the end that they may be made capable of applying increased leverage; and the invention consists in the combination of a longitudinallyslotted blade pivoted to a companion-blade through the medium of said slot, whereby the slotted blade is made capable of a combined longitudinal and swinging movement, and in pivotally connecting to each blade a rod which serves to guide and such an arrangement the slotted blade moves with a movement partaking equally of the longitudinal movement and the swinging movement, which results in a draw in the cut. The connecting rod, which is pivotally connected to the blades at its respective ends, is an important element of the invention, its function being to make the movements of the slotted blade regular and uniform, for without it the slotted blade would play idly upon the pivoting-spindle and would not perform that regular reciprocal and swinging movement which is essential to the effective operation of the invention. 7

In the drawings, Figure 1 represents a perspective view of a pair of scissors constructed after the manner of my invention, they being shown open; Fig. 2, a side elevation of the device, it being shown in a closed position; Fig. 3, a detail perspective of the slotted blade of the scissors, the view being shown as taken from the inner side thereof; Fig. 4, a section taken through the screw or spindle for holding the blades together.

The reference-numeral 1 indicates one blade of the scissors, and 2 the remaining blade. Each blade is provided with the hand-grasps 3, as usual, and the blade 2 is formed, near its shank, with a longitudinallyelongated slot 3, which has its inner sides formed with .rabbet-grooves 4:, capable of receiving the head of the screw 5, which screw is passed through the blade 1 and made rigid thereon. By this construction it will be seen that the blade 2 is capable of a limited longitudinal movement on the blade 1 in addition to its swinging movement, which is found. in all scissors. Formed in the blade 2 and at the inner side thereof, just rearward of the slot 3, is an indentation 6, in which the arm 7 is located and rigidly secured by riveting it to the blade 2. This arm lies flush with the inner side of the blade 2, so that the blades of the scissors may snugly engage each other. The arm 7 projects upwardly from the blade 2 and perpendicular from the same and has the arms 10 and projection 11 and by which the pivotal connection of the parts is efiected.

The use of myimprovement does not differ from the use of any other pair of scissors; but it will be observed that the operation thereof is radically different. Owing to the slot 3 and rod 9, the blade 2 is made to move on the blade 1, or viceversa, with a combined longitudinal and swinging movement, which gives rise to the draw in the cut and which at the same time adds leverage to the appliance and makes it easier to operate. The function of the rod 9 is performed by the said-rod swinging in the arc of a circle on the projection 11, which guides the blade 2 and causes the same to have its longitudinal movement.

Without this rod the blade 2 would play idly and disjointedly, so that the slot 3 would be ICO the blade 1, as this is the usual method of operating a pair of scissors. It will be obvious, however, that the description fits the reverse just as well, and therefore no further explanation of this point is necessary.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having described the invention, I claim In apair of scissors, the combination of two blades one of which is provided with a longitudinally elongated slot, a pin passing through said slot andinto the reinainingblade whereby said blades are connected so as to be capable of sliding one upon the other, an arm secured to the inner side of the slotted blade in rear of the slot, and a rod arranged outside of the plane of the blades and having one end piv- RUFUS PUTNAl.\'[ BOWDOIN.
