IMPROVEMENT IN TOP=FROFS FOR CARRIAGES.
Specification forming part of Letters Patent No. 124,991, dated March 5, 1872.
SPECIFICATION.
I, ANSON SEARLS, of Newark, county of Essex, State of New Jersey, have invented certain Improvements in Top-Props for Garriages,77 for which the following is a speciiication:
The nature and objects of my invention consist in the construction ot' top-props for carriages; and relates, iirst, to such a construction ot' the bow-plates as to strengthen the weak parts, and cause them to sit iirm on the bow where it maybe placed; second, to the construction of wha-t is known to the trade tion 'ot' cost is obtained and the appearance and strength at the same time improved by making the base tubular; third, to casting the nut with a semi-solid head, and with holes in the rim, into which the solder may run; fourth, to the combination of a lock-nut and the usual capped nut with the joint-bar standard for securely holding the prop-joints.
Figure l is a view of the prop and the nuts K and E. Fig. 2 is a longitudinal view of the same and of the silver cap S. Fig. 3 is aview ot' the base ot' the prop or bow-plate b, showing the concave forni of the base of the plate and the rim c. Fig. 4L is a transverse section of the plate b, at the-line showing the rim e and the concave form. Fig. 5 is a view of the nut E, cut awa-y so as to show a sectional view of the iiange B and the usual form otl casting by making the hole largestv at the top It. Fig. 6 is a transverse section of the nut E at the flange B, showing slots or holes h. Fig. 7 is a view ot' the nut E, when made with semi-solid head, with the smallest end ot the hole at the. top T and the rim j.
Common top props are usually made by casting the joint-bar standard and the bowplate in one piece, the standard having a ring or iiange around it to form the inside shoulder of the Ijoints. The improved props have been made by leaving off the ring or ange and passing a cap over the standard, so that it forms the inside shoulder ot' the prop-joints,` and also serves to cover 1 he hole in the leather when the bowplate is attached under the leather.
My improvement consists in attaching to the outer end ot the cap c the standard a., and to the sides ot' the base ot' the cap c the wings or plates Z1. The whole is cast in one piece and attached to the bow outside ot' the leather by screws passing through the wings B and leather into the bow. The usual plate and standard is not used in my improvement. The cavity d forming the cap c gives great strength to that part and renders it lighter and cheaper cast than the old `common prop,
. and gives it all the ornamental appearance of any improved prop. The base of bow-plates have'been made at and when attached to the bow do not sit iirm, from the fact that the bow at that place is not always iiat, and is sometimes covered with a yielding substance that allows the plate to roll. My improvement consists in making the base of the bowplate concave and providing it with a rim or raise, c, Figs. 3 and 4, on either side of the base of the plate that extends past the screwholes or entirely around the edge of the plate. The plate, whenput Aon the outside of the leather, as with common topprops, bears on the rim or edge e. The rim c may encircle the screw-holes to still further equalize the strength of the parts. The lock-nutK is used for the outside bearing ot' the prop-joints, and the nut E is screwed up jam against it. The two nuts E and K, combined with the standard a, make a secure bearing i'or the propjoints. The prop-nuts are usually made so that the hole runs straight through them, as shown in Fig. 5, and in such a manner that if screwed up a little too far the silver cap will be punched by the end of the prop or seat-rail and sometimes forces oi the cap. To remedy this I make the hole H in the outer end of thc nut smaller than on the inside, allowing a hole large enough at '.I, Fig. 7, for the core to prick through, and thereby assist it to stand while the nut is being cast. The nut is drilled out and tapered, leaving it with a semi-solid head, so that when screwed up the end of the prop cannot pass through and punch the silver. I also make the ange B, Fig. 6, with holes or slots b, through and into which the solder runs in capping, so that 4. The bow-plate b, when made conca-ve. on the base or provided with the rims e, substantially as described, and for the purpose set fort-h.
5. The semi-solid head-nut E.
6. The mit E, when provided with the holes h in the flange .B7 for the purpose set forth.
