SPECIFICATION forming part of Letters Patent No. 664,885, dated January 1, 1901.
Application filed May 2, 1900. Serial No. 15,228. (No model.)
To aZZ whom it may concern:
Be it known that I, JAMES JOSEPH MC- GRATH, a citizen of the United States, and a resident of Brookhaven, in the county of Lincoln and State of Mississippi, have invented new and useful Improvementsin Silk-Clamps, of which the following is a full, clear, and exact description.
The invention has for its object to provide a clamp adapted to bind a bolt of silk and retain the folds in proper position while exhibiting the goods.
In carrying out my invention I provide main clamp-arms and auxiliary inner clamp-arms to obtain a clamping action at two distant points, the inner clamp-arms being of novel form to prevent them from making an impression on the silk when several bolts are superposed.- This special arrangement of these inner clamp-arms is to be particularly ob served as forming an important element in eifecting the purpose of the device without danger of deteriorating the silk.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a perspective View representing my improved clamp applied to a bolt of silk, the latter being shown partly open to display the goods. Fig. 2 is a side elevation of the clamp on a larger scale, showing its position on the bolt; and Fig. 3'is a perspective View of the clamp detached from the bolt.
The main clamp-arms A are formed in a single piece of suitable spring metal, united at the U-bend a, and have sufficient length to take a proper bearing on the bolt D. The inner clamp-arms B B are continuous with the main arms and extend inwardly toward the U-bend a. One auxiliary clamp-arm B, it
will be observed, extends considerably beyond the companion arm B, and its projecting end I) is oifset toward the arm B, providing an extended surface beyond the said arm B and forming at the base of the offset part a depression I) at a point adjacent to the end of the shorter arm. The result of this arrangement is that neither of the auxiliary arms will be pressed into the silk when several bolts are superposed, and as the inner clamp-arms relieve or modify the clamping action of the ends of the outer arms the bolts and clamps will lie so nearly fiat as not to produce indentations in the silk. In exhibiting the goods the clamps preserve the original folds and will prevent the formation of additional creases, which without the clamp are a frequent occurrence and a cause of deterioration of the goods, necessitating a lowering of the selling price.
Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A clamp for silk and the like, comprising main clamp-arms, and auxiliary clamp-arms carried by the main clamp-arms and ranging in the opposite direction, said auxiliary clamparms being of unequal length and the longer one being offset, presenting a depressed portion opposite the shorter arm and affording a broad projecting end beyond said shorter arm.
2. A clamp for bolts of silk and the like, comprising main and auxiliary clamp-arms, the main arms being convergent to form clamping-surfaces, the said arms being curved outward at the outer ends and being returnbent, forming the auxiliary arms, the latter ranging inward from the outwardly-curved ends of the maixrarms, the inner ends of the auxiliary arms forming clamping-surfaces.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
