S. BENTLEY, OF JANESVILLE, WIS- CONSIN, ASSIGNORS TO SAID HANSON.
CLAMP.
SPECIFICATION forming part of Letters Patent No. 749,732, dated January 19, 1904.
Application filed. May 14, 1903.
To all whom it may concern.-
Be it known that we, HENRY M. HANSON and CHARLES S. BENTLEY, residents of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Clamps; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to an improved clamp, the object of the invention being to provide an improved clamp which will be quick acting in releasing and clamping and which will be extremely, simple in construction, comparatively cheap to manufacture, and mechanically perfect for the uses for which it is intended.
With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a View in side elevation, illustrating our improvements. Figs. 2 and 3 are views of the opposite ends thereof, and Fig. 4 is a bottom plan view.
1 represents the bar of my improved clamp, having notches 2 in its lower edge, and a movable tail-block 3 is located on this bar and a cross-pin 4: passed through the bar at one end to prevent the accidental removal of the tailblock. The tail-block is cast with an opening to receive the bar and has a cross-pin 5 at its lower edge to be moved into any of the notches in said bar and be held therein by a spring 6, which latter is secured to the block and bears against the upper edge of the bar, so that when the block is forced down or forward the pin can be released from the notches and the block moved up to the work, when the pin will engage the notch nearest to the work. On the opposite end of bar 1 our improved head-block 7 is located and comprises a casting having an angular bore to receive bar 1 and cast with an arched opening 8 in one side and an elliptical slot 9 in the other side oppo- Serial No. 157,117. (No model.)
site the same. The upper portion of said head block or casting forms an elongated internally -screwthreaded bearing 10 for the clamping-screw 11, which isdisposed parallel with bar 1 and has a swiveled head 12 on its inner end and a handhold 13 on its outer end.
In the arched opening 8 in head-block 7 a cam 14: is located and has a hollow lug 14 mounted in an opening in bar 1, and a rivet 16 is passed through this hollow lug and cam and through a washer 17 against the opposite face of bar 1 to pivotally secure the cam in position, and said cam has an arm 18 to facilitate its operation.
The operation of our improvements is as follows: The work is placed between the tailblock 3 and head-block 7 or, more correctly speaking, the latter are placed on opposite sides of the work, and the tail-block 3 moved up against the work as far as possible. The cam 14 is now operated to move the swiveled head 12 against the work and the screw turned by means of handhold 13 to securely clamp the work. When it is desired to release the clamp, the arm 18 on cam 17 is given a sharp blow with a wooden instrument to move the head-block 7 far enough to release the work, when the clamp will immediately drop therefrom, thus providing a quick release, which is an improvement on anything of this character heretofore known.
Various slight changes might be made in the general form and arrangement of the parts described without departing from our invention, and hence we would have it understood that we do not restrict ourselves to the precise details set forth, but consider ourselves at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of our invention.
Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is
1. In a clamp, the combination with a bar and a tail-block thereon, of a head-block mounted on said bar and having an opening in one side, a pin secured to the bar and projecting into said opening, a cam mounted on said pin and cooperating with a wall of the opening in the head-block and an adjustable clamp mounted in said head-block.
2. In a clamp, the combination with a bar and a movable tail-block thereon, of a headblock comprising a casting having a bore to receive the bar and open at its opposite sides, a cam pivotally secured to the bar in one of said openings and engaging the walls of said opening, and clamping means carried by the head block.
3. In a clamp, the combination with a bar and a movable tail-block thereon, of a headblock comprising a casting having a bore to receive the bar and an opening in one side, a cam mounted in said opening in engagement with the vertical walls thereof, a hollow lug on the cam pivotally secured to the bar, an arm on the cam, and a screw-plunger carried by said head-block.
4. In a clamp, the combination with a bar having notches in its lower edge and a tailblock on the bar having a cross-pin to engage in said notches and a spring to hold the pin therein, of a head-block on the opposite end of the bar, comprising a casting having a bore to receive the bar and openings in its opposite sides,a cam mounted in one of said openings and engaging the vertical walls thereof, a hollow lug on the cam mounted in an opening in the bar, a rivet passed through said hollow lug and through a washer against the face of the bar, an arm on said cam, an elongated internally-screw-threadedbearing integral with said block, a screw in said bearing disposed parallel with the bar, a swiveled head on one end of said screw and a'handhold on the other end of said screw.
In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
HENRY M. HANSON. CHARLES S. BENTLEY.
