PATENT JOHN H. FERGUSON, OF DAYTON, OHIO.
MECHANISM FOR HOLDING SAWS.
Application filed March 28, 1921.
To all whom it may concern:
Be it known that 1, JOHN H. FERcUsoN, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Mechanism for Holding Saws, of which the following is a specification, reference being had therein to the accompanying drawing.
My invention relates to a mechanism for holding saws while the teeth of the saw are being filed and adjusted.
The object of my invention is to provide a saw clamp that will automatically and resiliently embrace the saw so that it may be inserted with one hand into the clamp and will remain there without the necessity of using both hands, one for inserting the saw and the other for clamping the clamp upon the saw. Anothe object of my invention is to provide resilient supporting means for the clamps which may be positioned in any desired manner, having their lower ends brought close to one another or moved far away from one another being pivoted upon the clamps. The object of this is to provide room for the handle of the saw and to adjust the position of the clamps relative to any obstructions which may be upon the work bench. This greatly facilitates the attachment of the saw clamp to a window sill, to a work bench or any ledge, as the points of attachment may be regulated with respect to one another in the distance that separates them.
It is another object of my invention to provide a means of adjusting the clamping means to one another and for positively engaging the clamping means with the saw at the same time permitting of this adjustment of the supporting means about this positive adjustment of the clamping means.
Referring to the drawings:
Fig. 1, is a perspective of the complete mechanism; and,
Fig. 2, is a section on a vertical line through the supporting means and the clamping means, as well as the saw which is shown held in position.
In detail, 1 and 2 are the clamps embracing between them the saw 3. 1 has an aperture 4 in which a nose 5 projects and turns freely. This nose 5 is carried by one of the bifurcated resilient arms 6 of a support. This support is U-shaped and has a second arm 7 in Serial No. 456,313.
which is threaded screw 8 with a handle 9 that has a nose 1O projecting into an aperture 11 in the clamping means 2. This nose 10 turns freely in 11 but the shoulder 13 on the screw 8 abuts against the clamping means and serves to force it inwardly when the screw is threaded inwardly in 7 by the turning of the handle 9. One of the arms, constituting the bifurcated supporting means, has an outwardly and laterally projecting lug 1 1 on its upper portion and a similar lug bent in the opposite direction as at 15. This lug 15 has an eye 16 which is internally threaded and into which a locking screw 17, turned by a handle 18, is mounted. The support to which the saw clamp is attached is fitted between 14: and 15 against the edge 19 and clamped by 17 when 18 turns it in 16.
While I have shown and described certain features as constitutin m invention it will b y 7 Having thus fully described my invention,
what I claim as new and desire to secure by Letters Patent, is
1. In combination, a pair of parallel clamping plates having apertures therein, a U-shaped member with resilient arms at one end thereof having a nose on one of said arms inserted in one of said apertures and turning loosely therein, said member also having a threaded member with a nose thereon projected into another of the apertures of another plate, and having a shoulder on said threaded member engaging with the exterior of said plate, means of actuating said threaded member, and a second U-shaped member so pivotally connected at the other end of the plates, whereby a saw may be clamped between the parallel clamping plates and the clamping effect upon said saw increased against the resistance of said arms of the U-shaped members.
2. In combination, a pair of parallel clamping plates having apertures therein, a U-shaped member with resilient arms at one end thereof having a nose on one of said arms inserted in one of said apertures and turning loosely therein, said member also having a threaded member with a nose thereon projected into another of the apertures of another plate, and having a shoulder on said threaded member engaging with the exterior of said plate, means of actuating said threaded member, a second U-shaped member so pivotaliy connected at the other end of the plates, and means to attach said bifurcated members to a support and means for positively locking said bifurcated members to said support, whereby a saw may be clamped between rheparaiiel clamping plates and the clamping effect upon said saw increased 10 against the resistance of said arms of the U-slmped members.
In testimony whereof,1 affix my signature.
JOHN H. FERGUSON.
