SPECIFICATION forming part of Letters Patent No. 445,046, dated January 20, 1891. Application filed May 10, 1890- Serial No. 351,214. (No model.)

T0 JZ wh/011?, 'it may concern:

lie it known that l, JAMES C. Cess, a citizen of the United States, residing at Mansiield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Bow- Sockets for Buggy- '.lops; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to bow-sockets for buggy-tops, and is an improvement in the class of bow-sockets employing wood fillers and steel strengthening or re-ent'orcing plates or strips in conjunction with the wood filler, substantially as shown and described, and particularly pointed out in the claims.

ln the accompanying drawings, Figure l is a longitudinal central section of one of my improved sockets, showing the relation of the parts when united for use. Fig. 2 is a plain elevation of the form of wood iilling used. Fig. 3 is a perspective view of the steel strengthening-plate having its upper end broken ott. Fig. 4 is a crosssection of Fig. l on line .as and Fig. 5 is a cross-section on line y y, Fig. l. Fig. G is a side view of a portion of one of the usual slatirons. Fig. 7 is a longitudinal section ot one of the forward sockets without the steel plate.

lt is well known that the point of strain and breakage in a bow-socket is at or about its junction with the slat-iron, where to secure symmetry in construction and appearance and to effect the union with the extremity of the solid slatiron the tube providing the socket for the board is tapered and reduced to very slender proportions. Being thus reduced in size the tubeis necessarily weakened, and hence the danger of breakage. For this reason various means have been adopted by different manufacturers to overcome or remedy this danger and to render the socket strong and firm at this point.

Myimprovement is of the nature ol the earlier inventions in this art, in which a slotted wood ller was employed and a steel strip centrally in said filler, and is designed to overcome certain defects in such structures and to improve and simplify the same.

AV represents the usual tube, secured to the Slat-iron B at its lower end and providing a socket at its upper end for the bow C. The strengthening means are located wit-hin this tube, and consist in a wood iiller D, having a central longitudinal slot or slit d extending from the lower end ot the short stem d to near the top of the filler. The said filler has a long stem (Z2 extending down to the slatiron and a short stem adapted to work in connection with the plate E, as clearly shown in Fig. l. The filler is further constructed with beveled or cutaway corners d3, giving it a hexagonal form and adapting it better to lill the tube to the best advantage to impart to it the additional strength a strong wood filler affords, and yet leaving it out of contact with the tube at its iiat sides, so as to leave room for the inside seam a of the tube.

H eretofore when a filler was employed which fully occupied the tube at all points it was necessary to cut a longitudinal groove in the filler to accommodate said seam, and this necessitated the special handling of each and every filler and a special machine to vform said grooves, which was expensive in time and labor.

By my construction I sacrifice nothing of moment in strength, have firm bearings along the beveled edges in the tubes, and avoid the necessity of forming the groove u.. Any common planer suffices to make the iiller as used by me after it has been sawed one way to the tapering form adapting it to the tube, and this also avoids the special machinery necessary to give the iilicr its original outlines before grooving, which was necessary when it was made oval in cross'sectiou like the tube.

E represents the steel or other firm metalv plato. rllhis plate has its lower end, where the greater stress naturally comes, pressed into a substantially semicircular form in cross-'secr tion, or in such `form or curvature as will adapt it to the surface of the Slat-iron B about the neck thereof beneath the tube A. Thus constructed, the said plate is set edgewise across the direction of strain or stress, and by reason of being curved in cross-section a plate ot' a given size is great-lyincreased in strength. This also places it in the proper form to make an eiective weld with the Slat-iron, and in practice the said iron, the plate E, and the out- IOO 'claim as new, and desire to side tube are firmly welded together, nralzing a union 'that is' ei'zceedingly firm and sufficient to withstand the most excessive strains without danger of breaking. The fiat portion ot' the plate E occupies the slit in the wood filler, and the short stem d terminates at, the bend in said plate, whilethe long stem (Z2 goes down to the Slat-iron. It will be observed that the curved portion of the plate Eis also bent outward to fit closely against the inside of thc tube, whereby the strength of each part is reenforced by the strength of the other.

The foregoing description relates more especially to the rear bows, which take the greatest strain of the set.. The forward bows are made wthoutthe steel plate and use only the wood filling.

Having thus described the invention, what I secure by Letters Patent, is-

l. In a bow-socket, the tube and filler and a plate having its upper end in the filler and its lower end bent outwardand cu rved, substantially as described.

2. In a bow-socket, a strengthening-plate having itslower end curved in cross-section and secured upon the outside of 'the Slat-iron,

an outside tube, and awood filler having` stems or niere'at'lengths adapted 'to said strengthening-plate, substantially' as described.

In a bow-socket, a wood filler having beveled edges and fiat sides and stems of Varying lengths, and a strengthening-plate having a flat portion resting between said stems and a curved portion attached to the Slat-iron, and a tube inclosing' the said filler and plate, substantially as described.

4. In a bow-socket, an outside tube and a strengthening-plate rigid with the spindle of the Slat-iron and curved therewith at its lower end, in combination with a {illernhaving a central slitinclosing the iiatupper portion of said plate, substantially as described.

5. In a bow-socket, the combination of the tube A, the slotted Eller D, and the plate E, bent and curved at its lower end, substantially as described.

Titness my hand to the foregoing specification this th day of April, 1890.
