IMPRVEMBNT IN HARNESS-TRIMMINGS.

TO ALL WHOM IT MAY CNCERN:

A Be it known that I, MILTON A. FIsK, of- Springfield, in the county ot" Hampden, an d State of Massachu- Betts, have made and invented certain new and useful Improvements inthe Manufacture of HarnessTrimmings j and I do hereby declare the following to be a full, clear, and exact `description thereof, reference being-had to the annexed drawings, making-a part of this specification, in which- Figureris a. plan of the head or trimming, and

Figure 4 a section ofthe same', showing the insertion of the loop.

In the manufacture of harness-trimmings, sheet -brass or other metal is usually employed, from which such trimmings are struck up by means of dies, of any desired form oi' pattern, and the larger varieties strengthened by filling the-insides thereof with lead or some similar substance.

To the inside of these trimmings is attached, by means of solder, a stem or loop of wire, usually of brass or iron, whereby they are secured to harnesses, and the outside thereof is usually washed ori plated with a thin covering of silver, or some whitemetal or amalgam,lto impart an improved appearance. But such trimmings, being made of thin, 'light material, that they'may' the more readily receive the impression of the dies, are easily jammed or indented, and are often entirely detached fromthc stem or loop by failure oi" the solder to adhere; and'again, the wash or plate soon wears ed. when they assume a sullied, tarnished appearance.

My' invention, which has the same general appearance as the trimming above described 'when new, is designed to remedy the defects thereof, that is, to vproduce a trimming not casily jammed or indented, te which 'the loop is firmly attached, and whichwill preserve a clean,.white appearance, even after the wash or plate is wor'n oil'. p v I To enable others sl-rilled in the art to practise my invention, 'I will describe the construction thereoiaud my method of proceeding in manufacturingthe same. I

The head or trimming a a, I make of a round or circular form, about one inch and a halfl in diameter, as seen in g. 3, the face or outer surface thereof being convex, while the back or inner` surface is concave, and provided with slight sockets or projections around and 'for the support of the loop c c, as seen in fig. 4. By this method of construction I obtain great strength and durability without increase of heft or cost. vThe loop c c I construct of ordinary brass or iron wire ot' a size suilcient for strength, bending thewire a short distance from the head or trimming, nearly at'right angles, and the same again near the ends, as seen in'fig. 4L But as thehead or-ornnmenta a is of a thickness and of a metal or amalgam that could not be struck up with a die, I cast or run the same in a mould prepared for that purpose, and instead of soldering the loop c c to the head or ornament aa, I east or run such head or ornament on to such loop, thus producing the head or ornament a' a, and attaching thereto the loop c c in a irm and secure manner at one and the same operation.

,'The moulds which I employ are constructed of brass, ordinarily and on nearly the' same principle as a common bullet-mould, except that one of the jaws, which open laterally, is constructed to open through-the centre thereof horizontally, and provided with two small openings to each matrix to allow` the insertion of the loop co. Thematrix for the head or ornament is formed on the faces of the jaws ot" the mould which open laterally, and of any design desired, andthe opening for the melted metal or amalgam being on the top or upper side of the moulds, the matrix is so arranged that the melted amalgam, when poured in, strikes the outer-edge or circle of the head or ornament a aiirst. i

In the preparation of'the amalgam used for casting the head or ornament a a, I make use of. lead, antimony, and tin in the following manner and proportions: I melt' eight (S) parts ot' tin; and raise it to a red heat; I next add twelve (llparts of antimony, and as soon as the ant-imony is thoroughly dissolved, I add one hundred (100) parts of lead. When all are melted and thoroughly mixed, the amalgam is `then ready for use or casting. And it ils a peeuliarity of the amalgam prepared ,es above described, that it will run around the loop c c, penetrating and filling every crevice, figure, and interstice of the matrix, thus producinga very superior article of manufacture, und at the same time preserving a very smooth, clean appearanceund I do not know of any other metal or amalgam that `will answer lthe purpose of my invention so well as that herein set forth.

The moulds being properly prepared, I insert thev loop c c in the openings provided therefor', projecting the 'ends of the loop into the matrix suiciently to allow the melted amalgam to run round them' freely. I then pour in the metal-cir amalgam, and allow the same to coolor harden. I then remove the trimming from the mould, when it is ready-for cl'eaning,vand washing or plating with silver in the ordinary manner, if desired.

l Trimmings manufactured in the manner herein specified, I consider superior in quality, durability, and appearance to those manufactured-in the ordinary manner. Y l

I do not claim to have invented any new amalgam or composition, nor do I claim to have invented any article o f manufacture absolutely new in kind Vand unheard of before.

My invention relates to the improvement of an old manufacture, and consists in the construction of a rosetteor harness-trimming of,amn.terial and in a manner never before, to my knowledge, employed in such manufacture, the result of which is both a better and cheaper article, constituting an improvement ofthe trado.

Having thus described my invention and the methodof constructing the same, vwhatI claim as new, and for which I desire to' obtain Letters Patent, is- I As a new article of manufacture, a rosette or harness-trimming, when constructed as herein. described, and' for thepurpose speciied.v l
