  DESIGN FOR A MILITARY SCARF-PIN.
  
  SPECIFICATION forming part of Design No. 11,820, dated June 15, 1880. Application filed April 19, 1880.
  
  To all whom it may concern:
  Be it known that we, Clayton H. Case, a citizen of the United States, and residing at Hartford, in the county of Hartford and State of Connecticut, and William Riker, a citizen of the United States, residing in Clinton township, in the county of Essex and State of New Jersey, have jointly invented and produced a new and original Design for a Military Scarf-Pin, of which the following is a specification, reference being had to the accompanying illustration, which is a front view of the same.
  The letter a denotes an annulus or circlet, which may bear any appropriate legend or motto, or it may bear none. From the base periphery start a series of radial star-points, b.
  At the top of the annulus is the representation of a double-bladed battle-ax, c, the handle of which terminates in a spear-point, c'.
  At the bottom of the annulus is a dovetail-shaped piece, d, and to the small lug, d', depending from it a company letter, as A, B, &c., may be hung.
  The center of the annulus may be filled by an initial letter or monogram, as, in the present instance, the monogram "C. N. G.," standing for "Connecticut National Guard."
  The number of the regiment, as, in the present case, " 1," may be superimposed upon the circlet.
  We claim—
  1. The design for a scarf-pin, consisting of the annulus a, the peripheral star-points b, and the double battle-ax c, substantially as described, and shown in the accompanying illustration.
  2. The design for a scarf-pin, consisting of the annulus a, the peripheral star-points b, the double battle-ax c, the dovetail d, and the monogram within the annulus, substantially as described, and shown in the accompanying illustration.
