Application filed'hpril 3, 1911. Serial No. 618,503.

To all whom it may concern:

'Be it known-that I, JAMEsIS. Damn, it citizen of the United States,- residing at South Vienna, in the county of .Clark and 5 State of Ohio, have invented certain new and useful Improvements in Scissors, ofwhich thefollowing is'a specification, reference being had therein to the accompanying drawing.

object of the invention is to provide an ad justable stop to limit the movement of the cutting blades and enable the amount of this movement to'be regulated to maintain the cutting edges and points in proper relation one to the other. 7

It is a further object of the invention to provide such a stop which willbe concealed from view and will have no. projecting parts.

' L In the accompanying drawings, Figure is a side elevation of a pair of scissors em-' bodyingmy inventionfFig. 2'is, a side elevation of the inner side of one of the blades;

and 'Fig. 3.is a: similar view of the inner side of the other blade. 7

In these drawingsI haveillustrated one embodiment of my invention and have shown the same as applied to a pair of scissors such as are commonly used by bar-' bers, but it will be apparent that the invention can be applied to scissors or shears of various types. The scissors here shown are of the usual construction comprising the two intersecting blades 1 and 2 pivotally connected one to the other by a pivot screw 3. It will be noted that the inner faces of the blade members 1 and 2 are fiat throughout their length and have no shoulders or 40 projectingstops of any kind. The shanks of the blade members are slightly offset to bring the finger rings, indicated at 4 and 5, into substantially the same plane, but these rings-never come into engagement one with limit the movement of the intersecting blades about their'pivotal centers I have provided One of the blades with a recess, one end of which forms a stop and have provided the 59 other blade with a part adapted to enter the recess in the first blade and engage the stop to limit the relative movement of the blades. In the present instance I have shown the blade 2 as provided with a recess 6 tour and extends about the pivotal center of the blade. This recess has one end wall straight to form a shoulder, and, if desired, a wear plate, such as indicated at 7 may be mounted in that end of'the recess. The part carried by the other blade liadapted to enter the recess 6 in the blaile 2, preferably consists of a ball 8 mounted in a recess 9 in the inner surface of the blade 1 and of a diameter approximately twice the depth of the recess 9. The recess 9 is preferably elongated to allow the ball to have movement therein and-an adjustable stop is provided to limit the movement of the ball in one direction. This stop is here shown as comprising a screw 10 mounted in the edge of the blade 1 and having its inner end extending into the recess 9. By adjusting this screw the amount of movement permitted to the ball 8 is limited, and, consequently, the amount of movement permitted to the blades before the ball comes in contact with the fixed stop of the recess 6 maybe regulated.

It will be noted that I have provided the .throughout their length as the edges thereof gradually wear away from repeated sharpenings; and furtherI have eliminated the projecting parts or shoulders common to scissors and shears and often very objectionable, particularly in the case of barbers scissors. It will be further noted that the construction is an exceedingly simple one,

.requiring a minimum number of parts and having these parts of such a character that they can be provided very cheaply and will be subjected to little or no wear; and further, having the. parts ofsuch a character that the adjustment is. positive and very strong and not likely to become broken or disarranged. It will. also be noted that the finger rings 4 and 5 are connected with the shanks of the blades at points off their centers and near the inner edges thereof. This arrangement, particularly in the case of the ring 5, enables the finger which is inserted in the'ring to be supported in substantially the same plane with the other fingers, which rest upon the shank and upon the rearwardl rojecting lip, thus providing a finger su p iort which does not distort the fingers or tire the same.

While I have herein shown and described one form of my invention it will be understood that this form is chosen for the purpose of illustration only and that I do not Wish to be limited to the details of construction shown anddescribed, for obvious modifications will occur to a person skilled in the art.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. Scissors comprising a pair of intersecting blades pivotally connected one to 'the other, one of said blades having a recess in that side thereof adjacentto the other of said blades, a ball movably mounted in said recess, and an adjustable stop carried by the other blade to coiiperate with said ball to limit the movement of said blades about said pivotal connection.

2. Scissors comprising a pair of intersecting blades, a pivotal connection between said blades, one of said blades having an elongated recess therein and having a part forming a stop, the other of said blades also having an elongated recess in the inner surface thereof, a ball mounted in the recess in said second blade adapted to project into the recess in the first-mentioned blade, and adjustable means for limiting the movement of said ball.

3. Scissors comprising a pair of intersecting blades, a pivotal connection between said blades, one of said blades having an elongated recess therein and having a part forining a stop, the other of said blades also having an elongated recess in the inner surface thereof, a ball mounted in the recess in said second blade adapted to project into the recess in the first-mentioned blade, and a set screw mounted in the edge of said second blade and extending into the recess therein.

4. Scissors comprising a pair of intersecting blades, a pivot pin connecting said blades one to the other, one of said blades having a substantially semicircular groove arranged about said pivot in and having one end thereof shaped to orm a stop, the other of said blades having an elongated recess superadjacent to the first-mentioned recess, a ball mounted in the recess in said second blade and projecting into the recess in the first blade, and a set screw extending into the recess in said second blade to limit the movement of said ball therein.

In testimony whereof, I aflix my signature in presence of two Witnesses.
