I. HLGIP FINGL GASTER FOR TRUNKS.

Iva- 23,672. Patent ed Apr. 19, 1859;

ISAAC I-I. GIFFING, OF NE YORK, N. Y.

MODE OF ATTACHING GASTERS TO TRUNKS.

Specification of Letters Patent No. 23,672, dated April 19, 1859.

T 0 all whom it may concern:

Be it known that I, Isaac H. GIFFING, of the city and county of New York and State of New York, have invented a new and Improved Caster for Trunks or Boxes; and I do hereby declare that the following is a full and exact description, to wit:

The nature of my invention consists in providing a suflicient space between the plate and roller so that a band or strap of metal. (such as is now in use for strengthening trunks or boxes) may be passed. freely between the plate and roller, also making a flange continuously along the whole length of both sides of the plate in order to prevent the plate from twisting and also for the purpose of additional strength.

To enable others skilled in art to make and use my invention, I will proceed to describe its construction and operation.

I take a plate of iron or other strong metal about of an inch in thickness about 3 inches long and about 2-1- inches wide. I then mark two parallel lines along said plate lengthwise about of an inch from each edge see drawing No. 1. I then bend the plate at right angles along both lines and in the same direction so as to form a flange about of an inch high on both sides (or edges). I then mark off a line about an inch from one end and sloping downward toward the back of the plate so as to leave a flange of an inch high at one end and of an inch high at the other, see drawing No. 2. I then cut or file both flanges according to said sloping lines and file the highest part of the flange circular at the end, see drawing No. 2. I then drill two or more holes in the center part or back of the plate (for the purpose of fastening it on the trunk or box). I then drill a hole through the highest part or end of both flanges near the edge and so as to raise the roller from the back of the plate a sufficient distance to allow the strap or band (before mentioned) to pass along between the two flanges and also beneath the roller and between it (the roller) and the plate freely, the roller being placed between the flanges so as to project beyond the edges of the flange a suflicient distance. I now pass a strong Wire through the two flanges and roller, riveting both ends of said wire firmly, see drawing ITO. 3, or I may cut the plate of iron aforesaid in proper shape and then bend the flanges or else I may mold and cast the plates in the shape or form all as before described. The before mentioned dimensions are to be varied according to the size or strength re quired. The manner of using said caster is, to rivet, nail or screw the plate (through the holes in the back) on the trunk or boX then pass the strap or hand between the flanges, beneath the roller and between that and the plate, then bend the strap up to the side or end of the trunk and fasten there firmly by nailing or screwing or they may be both fastened together at one time.

I do not claim the roller or strap separately as they have been used 011 trunks for many years.

What I do claim is,

The method herein described of constructing and attaching casters to trunks.

I. H. GIFFING.
