A. G. STRATHERN. PLATE HOLDING ULAMP. APPLICATION FILED SEPT. 11, 1910.
1,01 1,660. Patented Dec. 12,1911.
ALEXANDER GEORGE STRATHERN, OF GARTSHERRIE, GOATBRIDGE, SCOTLAND.
PLATE-HOLDING- CLAMP.
Specification of Letters Patent.
Patented Dec. 12,1911.
Application filed September 8, 1910. Serial No. 580,995.
To all whom 'it may concern:
Be it known that I, ALEXANDER GEORGE STRATHERN, .a subject of the King of the United Kingdom of Great Britain and Ireland, and residing at Gartsherrie, Coatbridge, in the county of Lanark, Scotland, have invented a certain new and useful Iinprovement in Plate-Holding Clamps, of which the following is a specification.
This invention has for its object to provide an improved construction of automatically acting clamp for engaging and holding iron or steel plates or like articles when lifted or moved from point to'point.
In the accompanying drawings Figures 1 and 2 are elevations at right angles to each other showing one form of the improved clamp. Figs. 3 and 4 arelike views to Figs. 1 and 2 but show a modification.
Referring to the drawings, the clamp com-' prises a block A which is suspended bya link or lever B pivoted to it at C and connected by a pin D to a shackle E or chain link. The block A is provided with'depending portions forming between them a' space A into which the plate or other article may be passed. One of the depending portions of the block is preferably bifurcated as at- F and in said bifurcated depending portion is pivoted an eccentric or cam piece G which is onnected by a link or links H with a shackle pin D, as shown in Figs. 1 and 2, or with the lever B connected to said pin, as shown in Figs. 3 and 4, so that the weight of the block A and the plate or other article carried by it tending to operate the connections between the cam piece G and the shackle E tilts said cam piece so that it grips and clamps any article located in the space A between the de ending'portions of the block. The inside fiice of the depending'portion J of the block opposite the cam piece G is preferably serrated or roughened or fitted with a removable wearing piece as at K to insure that the plate or other article will be firmly gripped.- H aving now described my invention what I claim and desire to secure by Letters Patent of the United States is A plate holding clamp comprisinga, suspending member, a block having depending portions between which the plate is passed, one of said depending portions being bifurcated, a member pivoted to the block and connecting the block to the suspending memher, a cam member pivoted to said bifurcated depending portion and cooperating with the other of said depending portions,
and a connection between the cam member and said first named pivoted member.
In testimony. whereof I have slgned my name to this specification in the presence of two subscribing witnesses.
