March 4, 1930. KOKAY 1,749,491

CLAMP Filed March 26, 192'? W'Zmesses:

Patented Mar. 4, 1930 UNITED. STATES STEPHEN KOKAY, 01? CHICAGO, ILLINOIS CLAMP Application filed March 26, 1927. Serial No. 178,541.

My invention relates to a clamping device and more particularly to a quickly adjustable clamp, and the object of my invention is to provide a clamp as above indicated, which may be quickly and easily adjusted, a greatproportion of its range of action, and which is also provided with a fine adjusting means.

' Another object of my invention is to provide a clamp of the above indicated character which has a sleeve adapted to loosely engage the main portion of the clamping bolt for stiffeningthe same. and to prevent bending or buckling thereof.

My invention will be best understood by reference to the accompanying drawing forming a part of this specification and in which,

Figure 1 is a plan view partly in section of a clamping device incorporating my invention. I

Figure 2 is a side plan view of that disclosed in Figure 1.

' Figure 3 is a sectional view taken on approximately the line 33 of Figure 1.

Figure 4 is a sectional view taken on approximately the line 44 of Figure 1.

In the drawing and for the purpose of illustration I have shown the preferred embodiment of my invention comprising a main clamping jaw 5 having a clamping plate 6 integral therewith. The clamping jaw 5 is of the usual U shape construction, having a Y rounded portion 7 on one end through which the cylinder 8 is adapted to slide. The cylinder 8 is provided with a slot 9 and in this slot or keyway the end 10 of a set screw 11 is adapted to pass for preventing rotation of the cylinder 8 with respect to the member 7. Set screw 11 passes through an opening in the member 7 as shown in Figures 3 and 4.

The cylinder 8 is provided with notches 12 which are adapted to be engaged by a pawl 13, which is positioned in an opening 14 in one end of the U shaped jaw 5. The rearward end of said pawl is provided with a notch 15 into which a coil spring 16 is seated; the other end of said spring being positioned against a solid portion of said member and it is to be compressed in the openingl4 between the member 5 and the pawl 13 as shown 50 in Figures 3 and 4. The pawl 13 is provided held in its outwardly extending position as shown, by means of the spring 21 imprisoned between member 5 and the thumb cap 22. When it is desired to move the cylinder 8 with respect to member 5 it is only necessary to compress the plunger 20, causing the cam 19 to force the cam 18 backwardly against the spring 16 and, thereby, withdraw the forward end of pawl 13 from engagement in the notches 12 and, thereby, releasing the cylinder 8' so that it may be moved lengthwise through the portion 7, but the set screw 11 prevents rotary motion of said cylinder.

Through the cylinder 8 is a cylindrical opening 23 through which clamping bolt 24 is adapted to pass. One end of the opening 23 is threaded for screw thread engagement with bolt 24, and one end of bolt 24 is provided with ahead member 25 having a loosely titted cross-bar 26 passing through an open ing 27 therein for rotating said bolt. On the other end of the bolt 24 is provided a clamping member 28 having a ball socket 29 therein and having portions 30 secured about the spherical member 31 on the end of said bolt 24. As shown in Figures 1 and 4 a cover plate 32 is provided for the opening 14; said cover plate is provided with an inwardly extending shoe 33 for engagement with the side of pawl 13 for holding the same in place, and said cover plate 32 is held in place by suitable set screws 34 having screw thread engagement with member 5. i

From the foregoing description the operation of this device is believed to be obvious in that the clamping bolt 24 is movable relative to the cylinder 8 by means of screw thread engagement therewith, and the cylinder 8 is adjustable relative to member 5 by sliding through the rounded or cylindrical portion 7 thereof when the pawl 13 is released from engagement with the notches 12 as herein-before explained.

While I have described my invention in its rigv preferred form it is capable of variations without departing from the spirit of the in- V vention. I do not, therefore, wish to be limited to the precise details of construction set forth but desire to avail myself of such va-' riations and modifications as come within the scope of the appended claim.

I claim as my invention:

A clamp comprising a U-shaped clamping jaw having a clamping plate at one end thereof; a cylindrical opening through one end I thereof having a clamping bolt therethrough; a hollow cylindrical member surrounding said bolt and passing through said cylindrical opening; said member having screw thread engagement with said bolt;'notches in said cylindrical member; a pawl slidable in a direction at right angles to said cylindrical member and adapted to be yieldingly held in said notches; a manually operated push rod having a cam face engaging another cam face on said pawl for releasing said pawl from engagement with said cylindrical member; and a set screw engaging a slot in said cylindrical member for preventing rotary motion thereof. p

In testimony whereof I have signed my name to this specification. v 4
