Specification of Letters Patent No. 3,916, dated February 20, 1845.

To all 'whom t may concern: p

Be it known that I, JAMES W. NEWBERRY, of the Kensington district of the Northern Liberties, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful improvement on the tool or instrument called a shoemakers shoulder iron for setting and polishing the edge or forepart of the soles of boots and shoes; and I hereby declare the following to be a full and exact description.

The nature of my invention consits in so regulating by means of a screw and burs the extent of the surface designed for polishing, and the space for regulating the forepart or edge of the soles as to adapt it to size or thickness of any sole thus making one instrument answer for polishing and setting to a proper thickness-by well regulated guards-and sized sole, in which respect 1t difers from thecontrivance now 1n use- Ato wit-the present contrivance being the use of a separate instrument or tool for each sized sole, whereas my invent-ion makes one instrument or tool answer for any and every sized sole. i

To enable others skiled in the art to make and use my invention I will proceed to describe its construction and operation. The accompanying draft-plate No. 1, represents the instrument detached. The main arm B, is of iron (as is all the other parts of the instrument except the handle which is of wood) about an inch long and about inch square, from which project two parallel arms at right angles with B, marked 5, 6 and 5, each about ofan inch in length and about that distance from each other. On a line parallel with the under side of arm 6, at the opposite side, B bevels upward until it comes to a peak about i of inch above the top of arm on a line with the inside of B.

B and Z), b, are intended to support the instrument in general and slide A in particular, and bevels downward from the under side of arm Z9, b, until it joins the spiral stem which is inserted in the handle, the space formed by B b and b b forms 3 sides of a hollow square into which A, a square slide, intended to hold the screw D and suport guard a, t-s with exactness.

a is a projecting guard or arm about i of a inch in width, of the same thickness as slide A, to which it is connected by an elthe sole, and with the peak at the top of .B, which is inserted in the seam between the uper and the sole, regulates the thickness of the sole. Arm b is an half inch oval on the top, and of the same thickness as the space between guard a and slide A into which space it ts with exactness when the instrument is brought together; and is designed to polish the edge of the sole by pressing in against it and passing it there around.

In the angle formed by the peak at the top of B and arm b, is a small `head about the lg of an inch in size which is intended to compress the upper edge of the sole in the operation of polishing and setting it.

D is a screw about one inch in length and of an inch in diameter, firmly embedded in the inner side of slide A about the center thereof, and is designed to pass through the main arm B at E, which is a screw hole answering to the size of the screw, by means of which and the burs C, C, the instrument is connected, regulated and kept firm. a

C, C, are two burns about inch in di ameter and g of an inch thick which are screwed on screen 1), the one inside and the other outside of arm B. By turning these burs the parts of the instrument are brought nearer together or more widely separated, and thereby regulating the distance between the end of arm or guard a and the peak at the top of B which is the space used for polishing the edge of the sole. By this means the instrument is regulated so as to adapt it to the size of the thickness of any sole, thus making one instrument to answer for setting and polishing any size sole, while the burrs if one `be rmly secured against the inside and the other against the outside of arm B serves to keep the in strument rmly conected and the polishing and setting space true, after it is set and while in use. When thus set and regulatedV the instrument is used as the common shoulmanner described, the distance of these tWo der iron is used. parts being regulated substantially in the I claim as my invention and desire to semanner set forth. cure by Letters Patent- JAS.
