serssons on sHEARs.
Patented July 6, 1909.
Serial No. 417,727.
To all whom it may concern:
Be it known that I, JOHN H. KRoUsn, a citizen. of the United States, residing at Napoleon, in the county of Henry, State of Ohio', have invented certain new and useful Improvements in Scissors or Shears, of which the following is a description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates to scissors or shears; and the objects thereof are to provide an improved fastening bolt for pivotally securing the blades of the shears together, which bolt shall be capable of ready and ehiective adjustment to thereby keep the cutting edges in proper contact; and to provide a detachable and adjustable operating member or thumb hold whereby the distance the cutting edges pass by one another may be regulated and the shears thereby so adjusted that the points of the blades will always come together. Another advantage following from the use of a detachable thumb hold is that different sizes of thumb holds may be used with a given pair of she ars, and, furthermore, a given pair of shears may by means of my detachable thumb hold be readily and conveniently adapted for rightor forleft-handed persons.
In the drawing accompanying and forming a part of this application: Figure 1 is a view of a pair of shears to which my improvements are shown as applied, said view being principally in elevation; Fig. 2 is a sectional view taken along the blades of the shears and passing through the improved fastening bolt as indicated by the line a-t Fig. l 3 Fig. 3 is a perspective view of my improved bolt Whereby the blades of the shears are pivotally secured together. Fig. 4 is a view similar to Fig. 2, but in which a modified form of fastening bolt is shown, and, Fig. 5 is a sectional view illustrating the means whereby the detachable thumb hold is secured in place.
In the drawing, l and 2 are the blades of a pair of shears which blades are pivotally connected together intermediate their ends and have operating portions or members 3 and 4 adapted to be grasped by the fingers and thumb of the operator. l refer to the operating member 4 as an adjustable thumb hold, as when the shears are in use the operator will place his thumb within said. member, and this member 4 is detachably and adjustably secured. to the blade member as follows:
The said blade member is bent at right angles, as at 5, the bent over portion lying in the plane in which the blade oscillates when the shears are in use, as will be understood; and the thumb hold 4 is provided with a boss 6 having an opening 7 through which the bent portion 5 of the blade 1 passes.
8 is a set-screw for securing the thumb hold 4 in position, and 1.8 is a groove formed in the portion 5 into which the lower end of the set screw 8 enters.
With the above construction it will be evident that the farther the member 4 is moved to the left, Fig. l, the farther the points of the blades will pass each other before the member 4 engages the other operating member 3, and that by varying the position of the member 4 upon the bent portion 5 of the blade l the shears may be so adjusted that the points of the blades will always just come together or pass each other slightly, and a proper cutting action thereby secured. A further advantage following from the use of a detachable thumb hold as 4 is that different sizes of thumb holds to suit the requirements of different operators may be provided and attached. to a given pair of shears, and: a further advantage following from the use of a detachable thumb hold is that a given pair of shears may be supplied with a thumb hold adapted for a rightor a lefthanded person, as it will be understood that the thumb hold is interiorly beveled and shaped so as to fit the hand and thumb of the user, and that the required forms of y thumb hold for the right and for the left hand will be reversed.
Figs. 2 and 3 show my improved bolt whereby the blade members are pivotally connected together, and whereby they may be adjusted to keep the cutting edges in contact to thereby secure a proper cutting action of the shears. The said bolt comprises a body or shank portion 9 square or angular in cross-section, and a head portion 10 of cylindrical form, which latter portion forms a bearing for the blade member and is the only portion of the pivot or bolt which is subjected to wear. The head portion l0 has a bearing within a cylindrical recess 11 forme in the blade 1, which recess has an inwardly projecting ledge l2 forming the bottom of the recess 1l. and against which the under side of the cylindrical head portion 10 bears.
1,3 is an opening extending from the bottom l 0 ol the recess 11, the diameter whereof is slightly greater than the maximum diameter of the square body portion 9 of the bolt so as not to come into Acontact therewith. 14 is an opening through the blade member 2, the
form of which opening' corresponds with the cross-section of the body portion 9 of the bolt, and is square in the form shown in the drawing'. 15 is a screw engaging a threaded opening in the portion 9 oi the bolt, and the peripheryT of the head ol: said screw engages the blade 2 as will be understood from Fipg. 2.
fith a bolt constructed as above described it is evident that the body portion 9 will move with the blade 2, because of the engagement oi: the squared body portion with the correspondingly shaped openingl in the blade member 2, and it is also evident that the head portion 1() oi' the bolt is the onlyy portion thereof' that is subjected to wear.` The blades may be drawn together by means v of the screw 15, it being understood that a` slight space is left between the end of the body portion 9 and the under side of the head of the screw 15; and the screw 15 will notr tend to work loose when the shears are in use as there is no relative movement between the screw-head and the yblade 2.
cess 11 and the blades become worn so that the end of the body portion 9 comes into contact with the under side ol the head of the screw 15, thereby interfering with further adjustment, the bolt may be removed and the end of the part 9 filed or `around oil, whereby further capability of adjustment is secured without aiiecting the cutting qualities of the shears.
instead oi forming the fastening bolt with a square shank as 9 I may obviously use any form of construction of shank whereby the fastening bolt is caused to move with the blade member 2. I illustrate suoli a modiiication in Fig. 4 in which the shank oi2 the fastening bolt 115 is round and is provided with a slot 16 linto which the end of a set screw 17 enters. It will be seen that with this construction the fastening' bolt is caused to move with the blade member 2 by means of the engagement of the set screw 17 with the slot 1.6, and that the set screw when tightened ai'iords additional means for holding' the fastening bolt securely in position.
Having thus described my invention and explained the mode of operation thereof, l claim and desire to secure by Letters Patent:
1. In shears, blades provided. with cooperating` cutting portions and with operating` members which come into contact with one another when the shears are closed; a pivot intermediate said operating members and cutting portions for securing said blades together, and means whereby one oi' said operating members may be adjusted rel-atively to the remaining portion of the blade with which it is connected to kthereby regulate the :extent to which said cutting edges pass one another in the operation of the shears.
2. 1n shears, a blade member; an operating member means whereby Vsaid operating member may be adjusted in a direction at right angles to said blade member and in the plane of movement thereof when lthe if after long,- use the bottom 12 of the rej shears are in use; and means for securing said operating member in position upon said blade member.
3. In shears, a blade member having one of its ends bent at right angles and extending in the plane of movement of said blade when the shears are in use; an operating member supported by and movable upon the bent portion of said blade; and means for securing said operating member in position upon the bent portion of said blade.
This specification signed and witnessed this 1th day of February A. D. 1908.
JOHN H. KROUSE.
